Description

The present invention relates to absorbent articles.

2. Description of the Related Art Conventionally, an absorbent article is known that has an absorbent core and a waist elastic member that is arranged in a state of being stretched in the width direction in a waist region (see, for example, Patent Document 1).

The waist elastic member has a continuous elastic member and a discontinuous elastic member. The continuous elastic member extends continuously in the width direction from one outer side of the waist region to the other outer side. The discontinuous elastic member does not extend continuously in the width direction at least in the region overlapping the absorbent core in the thickness direction.

The shrinkage of the continuous elastic member and the non-continuous elastic member allows the waist region to fit the wearer's body, thereby suppressing the waist region from slipping toward the crotch side. On the other hand, since the contractile force of the waist elastic member is reduced in the region where the discontinuous elastic member does not extend continuously in the width direction, it is possible to suppress the contraction of the absorbent core in the width direction. As a result, the absorption area of the absorbent core is ensured, and excretion is suppressed from leaking from the waist opening side.

JP 2013-123447 A

The absorbent article of Patent Literature 1 has leg elastic members that are arranged outside the absorbent core in the width direction in the crotch region and that are arranged in a state of being stretched in the front-rear direction. Contraction of the leg elastic member pulls the crotch region toward the wearer's body. However, the crotch region could not be pulled up sufficiently, and the crotch region tended to hang down due to the weight of the absorbent core that had absorbed the excrement, especially after excretion. When the crotch region hangs down, the absorbent core is separated from the wearer's body, and there is a risk of side leakage of excrement.

Accordingly, the present invention has been made to solve the above-described problems, and in an absorbent article having a continuous elastic member and a discontinuous elastic member in the waist region, the leakage of excrement due to sagging of the crotch region is suppressed. An object of the present invention is to provide an absorbent article that can be

(1) Overview of Embodiments At least the following matters will become clear from the description of this specification and the accompanying drawings.

An absorbent article according to one aspect includes a waist region configured by a front-back direction, a width direction orthogonal to the front-back direction, a thickness direction, a first waist region and a second waist region, and the first waist region. and a crotch region sandwiched between the second waist region in the front-back direction, an absorbent core containing an absorbent material and disposed in the crotch region and at least the first waist region, and the width in the waist region a waist elastic member arranged in a state of being stretched in the direction; and a leg elastic member arranged in a state of being stretched in the front-rear direction, which is arranged outside the absorbent core in the width direction in the crotch region. and a member. The waist elastic member includes a continuous elastic member that extends continuously in the width direction from one outer side of the first waist region to the other outer side of the first waist region, and a continuous elastic member that extends at least in the center of the waist region in the width direction. and a discontinuous elastic member that does not extend continuously in a direction. The leg elastic member overlaps the continuous elastic member in the thickness direction outside at least one of the discontinuous elastic members in the front-rear direction.

Since the area overlapping the continuous elastic member in the thickness direction is brought into close contact with the body side of the wearer due to the contraction of the continuous elastic member, it is less likely to slip toward the crotch region. In addition, the leg elastic members arranged in the first waist region are easily fixed at positions overlapping the continuous elastic members in the thickness direction. As a result, the leg elastic members arranged in the crotch region are pulled up toward the first waist region by contracting the leg elastic members. Since the crotch region is pulled up by pulling up the leg elastic member, the crotch region can be suppressed from sagging and can be brought closer to the wearer's body. In addition, since the continuous elastic member overlaps the leg elastic member outside the discontinuous elastic member in the front-rear direction, the discontinuous elastic member overlaps the leg elastic member inside the continuous elastic member in the front-rear direction (that is, on the crotch region side). It is possible to suppress the contraction of the first waist region in the width direction and secure the absorption area. Therefore, it is possible to suppress lateral leakage of excrement due to drooping of the crotch region while suppressing contraction of the first waist region in the width direction.

According to a preferred aspect, the waist elastic member may have a second continuous elastic member continuously extending in the width direction from one outer side portion of the second waist region to the other outer side portion. The leg elastic member may be arranged at a position not overlapping the second continuous elastic member in the thickness direction in the second waist region. As a result, in a sleeping posture in which the first waist is on the upper side and the second waist region is on the lower side, the position of the end of the leg elastic member on the side of the second waist region is not fixed by the second continuous elastic member. The contraction of the leg elastic members makes it difficult for the crotch region to be pulled down toward the second waist region, while the contraction of the leg elastic members makes it easy for the crotch region to be pulled up toward the first waist region. As a result, the crotch region can be easily brought closer to the wearer's body in the sleeping posture, and side leakage of excrement due to hanging of the crotch region can be suppressed.

According to a preferred aspect, the first waist region may be a front waist region arranged on the abdomen side of the wearer. The wearer often sleeps (is laid) on his or her back with the ventral side facing up. Therefore, by making it easier to pull up the crotch area to the abdomen side by contraction of the leg elastic members, it is possible to easily suppress side leakage of excrement due to hanging down of the crotch area in the sleeping posture.

According to a preferred aspect, the waist elastic member may have a second continuous elastic member continuously extending in the width direction from one outer side portion of the second waist region to the other outer side portion. The leg elastic member may be arranged at a position overlapping the second continuous elastic member in the thickness direction in the second waist region. This makes it easier to fix the leg elastic members in both the first waist region and the second waist region. Therefore, the crotch region can be pulled up to both the first waist region and the second waist region by contraction of the leg elastic members, and especially in a standing posture, side leakage of excrement due to hanging down of the crotch region can be easily suppressed. .

According to a preferred aspect, the continuous elastic member may have an overlapping continuous elastic member overlapping the absorbent core in the thickness direction. The leg elastic member may overlap the overlapping continuous elastic member in the thickness direction. As a result, the absorbent core, which overlaps the overlapping continuous elastic member in the thickness direction, is brought into close contact with the wearer's body side due to the contraction of the overlapping continuous elastic member, and is less likely to slip toward the crotch region. Due to the weight of the absorbent core (especially the absorbent core that has absorbed excrement), it is possible to prevent the entire absorbent core from slipping toward the crotch region. In addition, the non-continuous elastic member prevents the absorbent core from shrinking in the width direction on the inner side of the overlapping continuous elastic member in the front-rear direction (that is, on the crotch region side), and the absorbent area can be secured.

According to a preferred aspect, the continuous elastic member overlapping the leg elastic member in the thickness direction may be composed of a plurality of elastic members spaced apart in the front-rear direction. The leg elastic member may overlap two or more elastic members among the plurality of elastic members in the thickness direction. The leg elastic members arranged in the first waist region are more easily fixed to the first waist region by overlapping two or more overlapping continuous elastic members in the thickness direction. As a result, the leg elastic members are contracted, so that the leg elastic members arranged in the crotch region can be easily pulled up toward the first waist region, and the crotch region can be easily pulled up.

According to a preferred aspect, the first waist region is a front waist region arranged on the abdomen of the wearer, and the second waist region is a rear waist region arranged on the back of the wearer. It's okay. The absorbent article includes a front exterior body arranged in the front waist region, a back exterior body arranged in the rear waist region, an outer portion of the front exterior body in the width direction, and the back exterior body. and a side joint that joins the widthwise outer portion. In the front waist region, the continuous elastic member overlapping the leg elastic member in the thickness direction extends rearward from the front edge of the side joint portion by 5% to 20% of the total length of the absorbent article in the front-rear direction. may be placed. Thereby, the continuous elastic member can be provided in the region of the lower end of the wearer's abdomen where the depression is likely to be arranged. Since the recess at the lower end of the wearer's abdomen tends to create a gap between the wearer and the front exterior body, the absorber can be easily bent in the front-rear direction along the recess at the lower end of the wearer's abdomen.

According to a preferred aspect, the length in the front-rear direction of the portion where the leg elastic member overlaps the first waist region in the thickness direction is such that the leg elastic member overlaps the second waist region in the thickness direction. It may be longer than the longitudinal length of the overlapped portion. As a result, the leg elastic members are brought into closer contact with the body side by the first waist region, so that the leg elastic members are more easily fixed in the first waist region. As a result, the leg elastic members contract, making it easier to pull up the leg elastic members arranged in the crotch region toward the first waist region, and the absorbent core can be brought closer to the wearer's body.

According to a preferred aspect, the continuous elastic member overlapping the leg elastic member in the thickness direction may have the greatest contractile force among the waist elastic members. As a result, the region where the continuous elastic member is arranged has a strong force to be brought into close contact with the body side of the wearer due to the contraction of the continuous elastic member, so that it is difficult to slip toward the crotch region. This makes it possible to firmly fix the leg elastic members while suppressing the first waist region from shifting toward the crotch region.

According to a preferred aspect, the contractile force of the continuous elastic member overlapping the leg elastic member in the thickness direction may be greater than the contractile force of the leg elastic member. Thereby, the leg elastic member can be firmly fixed at the position where the leg elastic member overlaps the continuous elastic member in the thickness direction. The contractile force of the leg elastic member can firmly pull up the crotch region and suppress the sagging of the crotch region.

According to a preferred aspect, the absorbent article may have an absorbent body containing the absorbent core. The absorbent body may have a low basis weight region in which the absorbent material has a lower basis weight than the surroundings. The overlapping continuous elastic member may overlap the low basis weight region in the thickness direction. Since the rigidity of the low basis weight region is lower than that of the surrounding area, the contractile force of the continuous elastic member overlapping the leg elastic member in the thickness direction is less likely to be hindered by the rigidity of the absorbent body. Due to the contraction of the continuous elastic member, the absorbent core in the low basis weight region can be brought closer to the wearer's body side, and the first waist region can be fitted to the wearer's body. In particular, since the absorbent material in the low basis weight region has a lower basis weight than the surrounding area, the absorbent body in the low basis weight region is relatively less likely to swell even if the absorbent body absorbs excrement. Therefore, even after excretion, the contraction of the continuous elastic member is less likely to be inhibited, and the first waist region can be fitted to the wearer's body even after excretion. As a result, it is possible to suppress leakage of excrement from the waist opening side while suppressing the first waist region from slipping toward the crotch region.

According to a preferred aspect, the discontinuous elastic member further includes an outer discontinuous elastic member arranged outside in the front-rear direction relative to the continuous elastic member overlapping the leg elastic member in the thickness direction. you can As a result, on the outer side of the continuous elastic member in the front-rear direction, the first waist region fits to the wearer's body side without being tightened on the center side in the width direction of the waist region, while the outer side of the wearer The contraction of the discontinuous elastic member allows the first waist region to fit around the wearer's body.

The continuous elastic member 55C continuously extends in the width direction W from one outer side portion of the front waist region S1 (or the rear waist region S2) to the other outer side portion. Of the continuous elastic members 55C, the continuous elastic member 55C arranged in one of the front waist region S1 and the rear waist region S2 is called a first continuous elastic member, and the continuous elastic member 55C arranged in the other is called a second continuous elastic member. You may call it an elastic member. For example, the continuous elastic member arranged in the front waist region S1 is the first continuous elastic member, and the continuous elastic member arranged in the rear waist region S2 is the second continuous elastic member.

The continuous elastic member 55C may have an overlapping continuous elastic member 55CO and a non-overlapping continuous elastic member 55CN. The overlapping continuous elastic member 55CO may overlap the absorbent core 31 in the thickness direction T on the outer side in the front-rear direction L of at least one of the non-continuous elastic members 55N. In the embodiment, the overlapping continuous elastic member 55CO overlaps the absorbent core 31 in the thickness direction T outside the inner non-continuous elastic member 55NA in the front-rear direction L, which will be described later.

As shown in FIG. 5, in the embodiment, the continuous elastic member 55C overlaps the leg elastic member 75 outside at least one of the discontinuous elastic members 55N in the front-rear direction L. In the embodiment, the overlapping continuous elastic member 55CO overlaps the leg elastic member 75 in the thickness direction T. As shown in FIG. As an example of the continuous elastic member 55C overlapping the leg elastic member 75 in the thickness direction T, the overlapping continuous elastic member 55CO will be described below. The overlapping continuous elastic member 55CO may overlap in the thickness direction T with the low basis weight region LR. On the other hand, the non-overlapping continuous elastic member 55CN does not need to overlap the absorbent core 31 in the thickness direction T. In addition, in the embodiment, the non-overlapping continuous elastic member 55CN does not overlap the absorbent main body 20 in the thickness direction T. As shown in FIG. The non-overlapping continuous elastic member 55CN may include an elastic member that overlaps the absorbent body 20 in the thickness direction T. As shown in FIG.

The overlapping continuous elastic member 55CO may be composed of a plurality of elastic members spaced apart in the front-rear direction L. In the embodiment, the overlapping continuous elastic member 55CO is composed of four elastic members.

The overlapping continuous elastic member 55CO is 5% of the total length of the absorbent article 1 in the front-rear direction L (from the front edge to the rear edge of the absorbent article 1) from the front edge 16F of the side joint portion 16 in the front waist region S1. may be positioned 20% posterior to the In the front waist region S1, the overlapping continuous elastic member 55CO is 20% to 90%, preferably 40% to 90% forward of the entire length of the side joint 16 in the front-rear direction L from the rear edge 16R of the side joint 16. It may be positioned 70% forward, more preferably 45% to 65% forward.

The continuous elastic member 55C may have an inner continuous elastic member 55CI. The inner continuous elastic member 55CI is arranged inside in the front-rear direction L from an inner edge 811E of the front-rear fixing portion 811, which will be described later. As in this embodiment, the overlapping continuous elastic member 55CO may have an inner continuous elastic member 55CI. Therefore, the inner continuous elastic member 55CI may overlap the absorbent core 31 in the thickness direction T. In addition, the inner continuous elastic member 55CI may overlap with the low basis weight region LR in the thickness direction T.

Like the overlapping continuous elastic member 55CO, the inner continuous elastic member 55CI extends rearward from the front edge 16F of the side joint portion 16 in the front waist region S1 by 5% to 20% with respect to the entire length of the absorbent article 1 in the front-rear direction L. may be placed. Similarly, in the front waist region S1, the inner continuous elastic member 55CI extends forward from the rear edge 16R of the side joint 16 by 20% to 90%, preferably 40%, of the total length of the side joint 16 in the front-rear direction L. 70% anterior to, more preferably 45% to 65% anterior to.

The inner continuous elastic member 55CI may be composed of a plurality of elastic members adjacent in the front-rear direction L. In this embodiment, of the four elastic members forming the overlapping continuous elastic member 55CO, the two elastic members arranged inside in the front-rear direction L are the inner continuous elastic member 55CI. Therefore, the inner continuous elastic member 55CI has a first inner continuous elastic member 55CIA and a second inner continuous elastic member 55CIB. The first inner continuous elastic member 55CIA is arranged on the innermost side in the front-rear direction L among the inner continuous elastic members 55CI. The second inner continuous elastic member 55CIB is adjacent to the first inner continuous elastic member 55CIA outside the first inner continuous elastic member 55CIA in the front-rear direction L.

Among the waist elastic members 55, the contractile force of the inner continuous elastic member 55CI may be the largest. Further, the contractile force of the first inner continuous elastic member 55CIA among the waist elastic members 55 may be the largest.

In this specification, the contractile force of the elastic member can be measured, for example, by the following method. The length H0 in the width direction W of the effective length portion of the elastic member is measured with the absorbent article 1 stretched to the maximum in the front-rear direction L to such an extent that wrinkles in the absorbent article 1 are no longer visible. Next, the elastic member is removed from the absorbent article 1, and the length H1 in the width direction W of the effective length portion of the elastic member is measured. Then, the contractile force of the elastic member can be calculated from "contractive force=H0/H1".

The continuous elastic member 55C may have an elastic sheet 55CS continuously extending in the width direction W from one outer side of the front waist region S1 to the other outer side. The stretchable sheet 55CS is a sheet-like elastic member. The length of the stretchable sheet 55CS in the front-rear direction L may be, for example, 5 mm or more. The elastic sheet 55CS may be made of, for example, an elastic resin film, an elastic non-woven fabric, or a combination thereof.

The stretchable sheet 55CS has stretchability at least in the width direction W and is arranged in a stretched state in the width direction W. As shown in FIG. The stretchable sheet 55CS may be arranged in the thickness direction T between the first front sheet 51F and the second front sheet 52F. The stretchable sheet 55CS may be arranged closer to the skin surface side T1 than the string-like or string-like waist elastic member 55 .

The elastic sheet 55CS may be fixed to the first front sheet 51F and/or the second front sheet 52F by the side joints 16 at the outer side portion of the elastic sheet 55CS in the width direction W while being stretched in the width direction W. . In addition, the stretchable sheet 55CS is formed such that at least a portion of the main surface of the stretchable sheet 55CS is bonded to the first front sheet 51F and/or the first front sheet 51F and/or the stretchable sheet 55CS by an adhesive portion (not shown) such as a hot-melt adhesive (HMA) or a sonic seal. and the second front seat 52F.

The discontinuous elastic member 55N does not extend continuously in the width direction W at least at the center of the waist region in the width direction W. The center of the waist region in the width direction W is a region extending from at least one outer end of the absorbent core 31 to the other outer end.

Compared to the region where the discontinuous elastic member 55N continuously extends in the width direction W, the contraction force in the width direction W is reduced in the region where the discontinuous elastic member 55N does not extend continuously in the width direction W. there is As a method of providing a region in which the discontinuous elastic member 55N does not extend continuously in the width direction W, for example, the following method can be used.

In a first method, the contraction area may be reduced by not placing the non-continuous elastic member 55N in a stretched state. For example, an adhesive (for example, hot melt adhesive (HMA)) for fixing the discontinuous elastic member 55N is placed in the region where the discontinuous elastic member 55N is arranged in a stretched state to reduce contractile force. An adhesive for fixing the non-continuous elastic member 55N is not disposed in the area where the elastic member 55N is to be stretched (hereinafter referred to as the low-shrinkage area LER). As a result, the discontinuous elastic member 55N is fixed in a stretched state in the area where the adhesive is applied. In the region where the adhesive is not arranged and which is sandwiched in the width direction W by the regions where the adhesive is arranged, the discontinuous elastic member 55N is maintained in the stretched state. By cutting the member 55N, the cut discontinuous elastic member 55N contracts. Thereby, the discontinuous elastic member 55N having contractility (that is, in a stretched state) is not arranged in the low-contraction region LER, and the low-contraction region LER can be provided. Therefore, the discontinuous elastic member 55N does not extend continuously in the width direction W in the low contraction region LER.

Note that when the low-contraction region LER (hereinafter referred to as the first low-contraction region LER1) is provided by the above-described first method, the discontinuous elastic member 55N may have fixed portions and non-fixed portions. A fixed portion is a portion that is arranged in an extended state. The unfixed part is the part that exists in the natural state without being fixed in the stretched state.

In a second method, the contractile force of the discontinuous elastic member 55N may be reduced by cutting (chopping) the discontinuous elastic member 55N fixed to the low contraction region LER at a plurality of locations. As a result, the discontinuous elastic member 55N does not extend continuously in the width direction W. As shown in FIG. In this case, even if the discontinuous elastic member 55N is fixed in the stretched state, the contractile force of the discontinuous elastic member 55N is reduced. In addition, since the non-continuous elastic member 55N with remaining contractile force is arranged (fixed) in the low-contraction region LER (hereinafter referred to as the second low-contraction region LER2) provided by the above-described second method, The contractile force of the second low-contraction region LER2 is generally greater than the contractile force of the first low-contraction region LER1.

The discontinuous elastic member 55N may have an inner discontinuous elastic member 55NA and an outer discontinuous elastic member 55NB. The inner discontinuous elastic member 55NA is arranged inside in the front-rear direction L from the overlapping continuous elastic member 55CO. The outer discontinuous elastic member 55NB is arranged outside in the front-rear direction L of the overlapping continuous elastic member 55CO.

As shown in FIG. 5, in the embodiment, the inner discontinuous elastic member 55NA does not extend continuously in the width direction W by the first method, thereby providing the first low-contraction region LER1. The inner discontinuous elastic member 55NA having contractility in the width direction W is not arranged in the first low contraction region LER1. Inner non-continuous elastic members 55NA are arranged on both outer sides in the width direction W of the first low contraction region LER1.

On the other hand, according to the second method, the outer discontinuous elastic member 55NB does not extend continuously in the width direction W, so that the second low contraction region LER2 is provided. An outer discontinuous elastic member 55NB is arranged in the second low contraction region LER2. The contractile force of the outer discontinuous elastic members 55NB arranged in the second low-contraction region LER2 is greater than the contractile force of the outer discontinuous elastic members 55NB arranged outside the second low-contraction region LER2 in the width direction W. is also low.

Next, the leg gathers 70 will be explained. The leg gathers 70 are gathers provided outside in the width direction W of the absorbent core 31 . The leg gathers 70 may be provided around the leg openings 18 and around the leg openings 18 . Further, it may be provided on the non-skin surface side T2 from the leg side gathers 80 .

The leg gathers 70 are pulled up toward the wearer's body by contraction of the leg elastic members 75 . The leg gathers 70 have leg elastic members 75 . The leg elastic members 75 are arranged outside in the width direction W of the absorbent core 31 in the crotch region S3. The leg elastic member 75 is arranged in a state of being stretched in the front-rear direction L. As shown in FIG. The leg elastic member 75 extends in the front-rear direction L at least in the crotch region S3. The leg elastic member 75 is arranged in the front waist region S1. The leg elastic member 75 may be arranged in the rear waist region S2.

As shown in FIG. 7 , in this embodiment, the leg elastic members 75 may be arranged on the leg side seats 47 . The leg elastic members 75 may be arranged in the thickness direction T between the leg side sheet 47 and the back sheet 42 . Further, the leg elastic members 75 may be arranged so as to be sandwiched between the leg side sheets 47 in the thickness direction T. As shown in FIG. Among the plurality of leg elastic members 75, some leg elastic members 75 (for example, the leg elastic members 75 arranged on the outermost side in the width direction W) are sandwiched between the leg side sheets 47 in the thickness direction T. may be placed. The leg elastic members 75 may be fixed to the leg side sheets 47 or may be fixed to the back sheet 42 . Therefore, the leg gathers 70 may be composed of the leg side sheets 47 in addition to the leg elastic members 75 . The leg gathers 70 may be composed of the leg elastic members 75 , the leg side sheets 47 and the back sheet 42 . Note that the leg elastic members 75 are arranged on other sheet members (sheet members other than the back sheet 42 and the leg side sheets 47) arranged outside the absorbent core 31 in the width direction W in the thickness direction T. may have been

As shown in FIG. 5, in the embodiment, the leg elastic member 75 overlaps the continuous elastic member 55C in the thickness direction T outside at least one of the discontinuous elastic members 55N in the front-rear direction L. The leg elastic member may overlap in the thickness direction T with the overlapping continuous elastic member 55CO. The leg elastic member 75 may overlap in the thickness direction T with two or more elastic members among the plurality of elastic members forming the overlapping continuous elastic member 55CO. In FIG. 5, the leg elastic member 75 overlaps in the thickness direction T with four overlapping continuous elastic members 55CO. In addition, the leg elastic member 75 overlaps the inner continuous elastic member 55CI in the thickness direction T. As shown in FIG. In addition, the leg elastic member 75 may overlap the discontinuous elastic member 55N in the thickness direction T. The leg elastic member 75 may overlap in the thickness direction T with the inner discontinuous elastic member 55NA. The leg elastic member 75 may be arranged at a position not overlapping in the thickness direction T with the outer discontinuous elastic member 55NB.

The leg elastic member 75 may overlap the elastic sheet 55CS in the thickness direction T as the continuous elastic member 55C. Therefore, in the front-rear direction L, the inner edge in the front-rear direction L of the elastic sheet 55CS may be located inside the outer edge in the front-rear direction L of the leg elastic member 75 .

In addition, the leg elastic member 75 may be arranged at a position not overlapping the continuous elastic member 55C in the thickness direction T in the rear waist region S2. The leg elastic member 75 may overlap the non-continuous elastic member 55N in the thickness direction T in the rear waist region S2, or may be arranged at a position where it does not overlap.

As shown in FIG. 5, the length L1 in the front-rear direction L of the portion where the leg elastic member 75 overlaps the front waist region S1 in the thickness direction T is such that the leg elastic member 75 overlaps the rear waist region S2 in the thickness direction T. It may be longer than the length L2 in the longitudinal direction L of the portion. When the leg elastic member 75 overlaps the front waist region S1 and does not overlap the rear waist region S2 in the thickness direction T, the length L1 is longer than the length L2 because the length L2=0.

The overlapping continuous elastic member 55CO that overlaps the leg elastic member 75 in the thickness direction T may have the largest contractile force among the waist elastic members 55 . When overlapping continuous elastic member 55CO is composed of a plurality of elastic members, one of the plurality of elastic members may have the largest contractile force among waist elastic members 55 . Of the overlapping continuous elastic members 55CO that overlap the leg elastic members 75 in the thickness direction T, the overlapping continuous elastic member 55CO (the innermost continuous elastic member 55CIA in FIG. 5) located on the innermost side in the front-rear direction L has the highest contractile force. Large is fine.

Moreover, the contractile force of the overlapping continuous elastic member 55CO overlapping the leg elastic member 75 in the thickness direction T may be greater than the contractile force of the leg elastic member 75 . The contractile force of one or more overlapping continuous elastic members 55CO among the overlapping continuous elastic members 55CO may be greater than the contractile force of the leg elastic member 75 . The contractile force of all overlapping continuous elastic members 55CO may be greater than the contractile force of the leg elastic member 75 . Alternatively, the contractile force of the leg elastic member 75 may be greater than the contractile force of the overlapping continuous elastic member 55CO overlapping the leg elastic member 75 in the thickness direction T.

Here, as shown in FIG. 8A, the leg elastic member 75 does not overlap the continuous elastic member 55C in the thickness direction T in the conventional absorbent article. In this case, in the front waist region S1, a sufficient force is not applied to the leg elastic members 75 toward the skin surface side T1, so the positions of the leg elastic members 75 are difficult to fix. For this reason, the leg elastic member 75 tends to separate from the body or to move rearward in the front-rear direction L. Therefore, contraction of the leg elastic members 75 causes not only a force directed toward the front waist region S1 but also a force directed toward the rear waist region S2 to act on the leg elastic members 75 . As a result, as shown in FIG. 8A, when the wearer raises the leg in the supine sleeping position, the leg elastic members 75 arranged in the crotch region S3 are sufficiently pulled up toward the front waist region S1. Therefore, as shown by the outline 20L of the absorbent main body 20, the crotch region S3 is likely to be maintained in a drooping state. In this case, since the absorbent core 31 is separated from the wearer's body, excrement may leak sideways. In particular, after excretion, the weight of the absorbent core 31 that has absorbed excrement causes the crotch region S3 to sag, so that the excrement that the absorbent core 31 could not absorb may leak in the width direction W in the crotch region S3.

As described above, the leg elastic member 75 overlaps the continuous elastic member 55C in the thickness direction T in the embodiment. Due to the contraction of the continuous elastic member 55C, force is applied to the leg elastic member 75 toward the skin surface side T1. Therefore, as shown in FIG. It becomes easy to be fixed at the position P1 overlapping in the thickness direction T. As a result, the leg elastic member 75 contracts, and a force F acts on the leg elastic member 75 in the direction toward the position P1. Therefore, for example, as shown in FIG. 8B, when the wearer raises the leg in a supine sleeping position, the leg elastic members 75 arranged in the crotch region S3 are pulled up toward the front waist region S1. . As shown by the outline 20L of the absorbent main body 20 in FIG. 8A, the crotch region S3 is pulled up by pulling up the leg elastic member 75. In FIG. As a result, sagging of the crotch region S3 can be suppressed, and the absorbent core 31 can be brought closer to the wearer's body.

Furthermore, since the region overlapping the continuous elastic member 55C in the thickness direction T is brought into close contact with the body side of the wearer due to the contraction of the continuous elastic member 55C, it is difficult to shift toward the crotch region S3. In addition, the continuous elastic member 55C overlaps the leg elastic member 75 outside the inner non-continuous elastic member 55NA in the front-rear direction L. In the region where the inner discontinuous elastic member 55NA does not extend continuously in the width direction W, the contractile force is reduced compared to the portion where the inner discontinuous elastic member 55NA extends continuously. It is possible to suppress the front waist region S1 from shrinking in the width direction W on the inner side in the front-rear direction L (that is, on the crotch region S3 side) of 55C (overlapping continuous elastic member 55CO in the embodiment), and to ensure an absorbent area. . Therefore, it is possible to prevent the front waist region S1 from shrinking in the width direction W, and to prevent side leakage of excrement caused by the drooping of the crotch region S3.

Further, the leg elastic member 75 may be arranged at a position not overlapping the continuous elastic member 55C in the thickness direction T in the rear waist region S2. As a result, as shown in FIG. 8A, in a sleeping posture in which the front waist region S1 is on the upper side and the rear waist region S2 is on the lower side, the end portion of the leg elastic member 75 on the side of the rear waist region S2 is aligned with the rear waist region S2. Since the position is not fixed by the continuous elastic member 55C of the region S2, the contraction of the leg elastic member 75 makes it difficult for the crotch region S3 to be pulled down toward the back waist region S2, and the contraction of the leg elastic member 75 causes the crotch region S3 to move toward the front waist region. It can be easily pulled up to the area S1 side. As a result, in the sleeping posture, the front waist region S1 can be easily brought closer to the wearer's body, and the lateral leakage of excrement due to the drooping of the crotch region S3 can be suppressed.

Further, the first waist region where the leg elastic member 75 overlaps the continuous elastic member 55C in the thickness direction T may be the front waist region S1. The wearer often sleeps (is laid) on his or her back with the ventral side facing up. Therefore, by making it easier to pull up the crotch region S3 to the ventral side by contraction of the leg elastic members 75, it is possible to easily suppress side leakage of excrement due to hanging down of the crotch region S3 in the sleeping posture.

Also, the leg elastic member 75 may have an overlapping continuous elastic member 55CO. As a result, the absorbent core overlapping the overlapping continuous elastic member 55CO in the thickness direction is brought into close contact with the body side of the wearer due to contraction of the overlapping continuous elastic member 55CO, so that it is difficult to shift toward the crotch region. The weight of the absorbent core 31 (in particular, the absorbent core 31 that has absorbed excrement) can prevent the entire absorbent core 31 from slipping toward the crotch region. In addition, inside the overlapping continuous elastic member 55CO in the front-rear direction L (that is, on the side of the crotch region S3), the inner discontinuous elastic member 55NA prevents the absorbent core 31 from shrinking in the width direction, thereby ensuring an absorbent area. can be done.

Further, the leg elastic member 75 may overlap in the thickness direction T with two or more elastic members among the plurality of elastic members forming the continuous elastic member 55C. The leg elastic members 75 arranged in the front waist region S1 overlap two or more continuous elastic members 55C in the thickness direction T, so that they are more easily fixed to the front waist region S1. As a result, the leg elastic members 75 contract, so that the leg elastic members 75 arranged in the crotch region S3 can be easily pulled up toward the front waist region S1, and the crotch region S3 can be easily pulled up.

Further, in the front waist region S1, the continuous elastic member 55C overlapping the leg elastic member 75 in the thickness direction T extends from the front edge 16F of the side joint portion 16 to 5% to 20% of the total length of the absorbent article 1 in the front-rear direction L. % backwards. Thereby, it is possible to provide the continuous elastic member 55C in a region of the lower end of the abdomen of the wearer where the depression is likely to be arranged. Since the recess at the lower end of the wearer's abdomen tends to create a gap between the wearer and the front exterior body 50A, the absorber 30 (absorbent core 31) is moved in the front-rear direction L along the recess at the lower end of the wearer's abdomen. It can be made easy to bend. As a result, in the front-rear direction L, the absorbent body 30 can be arranged along the abdomen that protrudes from the recess at the lower end of the abdomen of the wearer, and the absorbent body 30 can be fitted to the wearer's body in the front-rear direction L. .

Further, the continuous elastic member 55</b>C overlapping the leg elastic members 75 in the thickness direction T may have the largest contractile force among the waist elastic members 55 . As a result, the area where the continuous elastic member 55C is arranged has a strong force of being brought into close contact with the body side of the wearer due to the contraction of the continuous elastic member 55C, so that it is difficult to shift toward the crotch region S3. This makes it possible to firmly fix the leg elastic members 75 while suppressing the entire absorbent core 31 from shifting toward the crotch region S3.

Further, the contractile force of the continuous elastic member 55</b>C overlapping the leg elastic member 75 in the thickness direction T may be greater than the contractile force of the leg elastic member 75 . Thereby, the leg elastic member 75 can be firmly fixed at a position where the leg elastic member 75 overlaps the continuous elastic member 55C in the thickness direction T. The contractile force of the leg elastic member 75 can firmly pull up the crotch region, thereby suppressing the sagging of the crotch region S3.

Further, the continuous elastic member 55C overlapping the leg elastic member 75 in the thickness direction T may overlap the low basis weight region LR in the thickness direction T. Since the rigidity of the low basis weight region LR is lower than that of the surrounding area, the shrinkage force of the continuous elastic member 55C is less likely to be hindered by the rigidity of the absorber 30 . The contraction of the continuous elastic member 55C allows the absorbent core 30 in the low basis weight region LR to be brought closer to the wearer's body, and the front waist region S1 to fit the wearer's body. In particular, since the low basis weight region LR has a lower basis weight of the absorbent material than the surrounding area, the absorbent body 30 in the low basis weight region LR is relatively less likely to swell even if the absorbent body 30 absorbs excrement. Therefore, even after excretion, the contraction of the continuous elastic member 55C is less likely to be inhibited, and the front waist region S1 can be fitted to the wearer's body even after excretion. As a result, it is possible to suppress the leakage of excrement from the waist opening 17 side while suppressing the shift of the front waist region S1 toward the crotch region S3.

In addition, the discontinuous elastic member 55N may further include an outer discontinuous elastic member 55NB arranged outside in the front-rear direction L relative to the continuous elastic member 55C overlapping the leg elastic member 75 in the thickness direction T. As a result, on the outer side in the front-rear direction L of the continuous elastic member 55C overlapping the leg elastic member 75 in the thickness direction T, the center side in the width direction W of the front waist region S1 is not tightened toward the wearer's body, and the front waist is stretched. While fitting the region S1, the contraction of the outer discontinuous elastic member 55NB allows the front waist region S1 to fit along the wearer's body on the lateral side of the wearer.

Next, the leg side gathers 80 will be explained. The leg side gathers 80 are gathers that can stand up on the skin surface side T1. It may be provided closer to the skin surface side T1 than the leg side gathers 80 are. The leg side gathers 80 may have fixed portions 81 and standing portions 82 .

The fixing portion 81 fixes the leg side seat 47 . Specifically, the fixing portion 81 fixes a portion of the leg side seat 47 to which the leg side elastic member 85 is fixed to a member located on the non-skin surface side T2 of the portion of the leg side seat 47 . . In the embodiment, the third portion 473 of the leg side seat 47 is fixed to the fourth portion 474 by the fixing portion 81 . The fixing portion 81 may be configured by, for example, an adhesive portion such as a hot melt adhesive (HMA) or a sonic seal.

The fixing portions 81 include a front-rear fixing portion 811 that fixes the leg side seat 47 outside the standing portion 82 in the front-rear direction L, and a width fixing portion that fixes the leg side seat 47 outside the standing portion 82 in the width direction W. 812 and . The front and rear fixing part 811 may have a front fixing part arranged in the front waist region S1 and a rear fixing part arranged in the rear waist region S2.

In the embodiment, the front-rear fixing portion 811 has an inner edge 811E on the inner side in the front-rear direction L. As shown in FIG. 55 C of continuous elastic members are arrange|positioned inside the front-back direction L from the inner edge 811E of the front-back fixing part 811. As shown in FIG. Specifically, the inner continuous elastic member 55CI is arranged inside in the front-rear direction L from the inner edge 811E of the front-rear fixing portion 811 . Further, the overlapping continuous elastic members 55CO other than the inner continuous elastic member 55CI are arranged outside in the front-rear direction L of the inner edge 811E of the front-rear fixing portion 811 . In addition, the front-rear fixing portion 811 has an inner edge 811S on the inner side in the width direction W. As shown in FIG. The inner edge 811S of the front-rear fixing portion 811 may be arranged in the low-contraction region LER where the discontinuous elastic member 55N does not extend continuously in the width direction W.

As shown in FIG. 6, the absorbent core 31, the standing portion 82, and the inner continuous elastic member 55CI may overlap in the thickness direction T. As shown in FIG. Further, when the absorbent core 31 is provided with a compressed portion, the compressed portion, the standing portion 82 and the inner continuous elastic member 55CI may overlap in the thickness direction T.

As shown in FIG. 7B , the standing portion 82 can be raised by contraction of the leg side elastic member 85 . The standing portion 82 can be raised using the boundary between the standing portion 82 and the fixed portion 811 as a base point. Specifically, in the width direction W, the standing portion 82 can be raised with the inner edge of the width fixing portion 812 in the width direction W as a base point. It can stand up with the edge 811E as a base point. However, as will be described later, when the continuous elastic member 55C (inner continuous elastic member 55CI) is arranged inside in the front-rear direction L of the inner edge 811E of the front-rear fixing portion 811 in the front-rear direction L, the contraction The portion can stand up from a position SP overlapping the inner continuous elastic member 55CI in the thickness direction T as a base point.

The leg side elastic member 85 is arranged on the leg side seat 47 while being stretched in the front-rear direction L. As shown in FIG. In this embodiment, the leg side elastic members 85 are sandwiched between the leg side sheets 47 . The leg side elastic member 85 may be composed of a single elastic member, or may be composed of a plurality of elastic members spaced apart in the width direction W. As shown in FIG. In this embodiment, it is composed of two elastic members. The leg side elastic member 85 may be configured by a string-like or string-like elastic member extending in the front-rear direction L. As shown in FIG. The leg side elastic member 85 is arranged on the leg side seat 47 while being stretched in the front-rear direction L. As shown in FIG. In this embodiment, the leg side elastic members 85 are sandwiched between the leg side sheets 47 . Specifically, it is arranged between the second portion 472 and the third portion 473 of the leg side seat 47 . The leg side elastic member 85 may be fixed to at least one of the second portion 472 and the third portion 473 of the leg side seat 47 .

The contractile force of the inner continuous elastic member 55CI overlapping the leg side elastic member 85 in the thickness direction T may be greater than the contractile force of the leg side elastic member 85 .

Here, as shown in FIG. 9A, in the conventional absorbent article, the continuous elastic member 55C is not arranged inside the inner edge 811E of the front-rear fixing portion 811 in the front-rear direction L. As shown in FIG. Therefore, as usual, the standing portion 82 stands with the inner edge 811E of the front-rear fixing portion 811 as a base point. Therefore, the vicinity of the inner edge 811E of the front-rear fixing portion 811 is likely to separate from the wearer's body, and a gap G is likely to occur between the absorbent article and the wearer's body. Therefore, there is a problem that the excrement that has diffused on the absorbent body 30 toward the waist area tends to spread in the width direction W, thereby causing side leakage.

As described above, in the embodiment, the continuous elastic member 55C has the inner continuous elastic member 55CI that is arranged inside in the front-rear direction L from the inner edge 811E of the front-rear fixing portion 811 . As shown in FIG. 9B, the inner continuous elastic member 55CI is arranged inside in the front-rear direction L of the inner edge 811E of the front-rear fixing portion 811, and therefore inside the front-rear fixing portion 811 in the front-rear direction L. The standing portion 82 located and the inner continuous elastic member 55CI overlap in the thickness direction T. As shown in FIG. Therefore, at the position where the standing portion 82 and the inner continuous elastic member 55CI overlap, the standing portion 82 can be brought into close contact with the body. As a result, it is possible to prevent excrement from reaching the outer side of the standing portion 82 in the front-rear direction L, and prevent excrement from diffusing in the width direction W from the outer side of the standing portion 82 in the front-rear direction L. can be suppressed. On the other hand, inside the position SP where the standing portion 82 and the inner continuous elastic member 55CI overlap in the front-rear direction L, contraction of the leg side elastic member 85 allows the standing portion 82 to stand with the overlapping position SP as a base point. Excrement spreading in the width direction W on the absorbent body 30 can be blocked.

Furthermore, due to the contraction of the continuous elastic member 55C, the region where the continuous elastic member 55C is arranged adheres closely to the wearer's body. On the other hand, since the discontinuous elastic member 55N does not extend continuously in the width direction W inside the inner continuous elastic member 55CI in the front-rear direction L, there is a low contraction region LER where the contraction force in the width direction W is low. . As a result, the inner side in the front-rear direction L of the inner continuous elastic member 55CI is relatively easily separated from the body side. As described above, it is possible to suppress leakage of excrement that has diffused on the absorbent body 30 toward the front waist region S1 side.

In addition, the inner continuous elastic member 55CI may be composed of a plurality of elastic members adjacent in the front-rear direction L. As a result, the standing portion 82 can be brought into planar contact with the body, and the standing portion 82 can be firmly fixed at the position SP where the standing portion 82, the inner continuous elastic member, and 55CI overlap. Therefore, it is possible to prevent excrement from reaching the outer side in the front-rear direction L of the upright portion 82 . As a result, it is possible to prevent excrement from diffusing in the width direction W from the outer side in the front-rear direction L of the upright portion 82 .

In addition, among the waist elastic members 55, the contractile force of the inner continuous elastic member 55CI may be the largest. By increasing the contractile force of the inner continuous elastic member 55CI, the upright portion 82 can be brought into close contact with the body. As a result, it is possible to prevent excrement from diffusing in the width direction W from the outer side in the front-rear direction L of the upright portion 82 . In addition, by bringing the standing portion 82 into close contact with the body, the inner portion in the front-rear direction L of the overlapping position SP between the standing portion 82 and the inner continuous elastic member 55CI becomes more likely to separate from the body side. This makes it easier to raise the standing portion 82 with the overlapping position SP as a base point, and can block the excrement spreading in the width direction W on the absorbent body 30 .

In addition, among the waist elastic members 55, the contractile force of the innermost continuous elastic member 55CIA may be the largest. The innermost continuous elastic member 55CIA can be tightly attached to the body, and excrement can be prevented from reaching the outer side in the front-rear direction L beyond the innermost continuous elastic member 55CIA. In addition, since the standing portion 82 rises from the position SP where the standing portion 82 and the innermost continuous elastic member 55CIA overlap, the contracting force of the innermost continuous elastic member 55CIA is maximized, so that the standing portion 82 can be raised. It is possible to block the excrement spreading on the absorbent body 30 in the width direction.

In addition, the inner continuous elastic member 55CI may overlap the low basis weight region LR in the thickness direction. As a result, the rigidity of the low basis weight region LR becomes lower than that of the surrounding area, so that the contractile force of the inner continuous elastic member 55CI is less likely to be hindered by the rigidity of the absorber 30 . In particular, since the low basis weight region LR has a lower basis weight of the absorbent material than the surrounding area, the absorbent body 30 in the low basis weight region LR is relatively less likely to swell even if the absorbent body 30 absorbs excrement. In particular, in the present embodiment, the grammage of the low grammage region LR is 0, so swelling of excrement can be suppressed. Therefore, even after excretion, the contraction of the overlapping continuous elastic member 55CO is less likely to be inhibited. Therefore, the contraction of the inner continuous elastic member 55CI allows the region overlapping the inner continuous elastic member 55CI in the thickness direction T to be brought closer to the body side of the wearer. Therefore, it is possible to prevent excrement from reaching the outer side in the front-rear direction L of the inner continuous elastic member 55CI. In addition, the erecting portion 82 can be easily erected, and the excrement diffusing in the width direction W on the absorbent body 30 can be blocked.

Also, the absorbent core 31, the standing portion 82, and the inner continuous elastic member 55CI may overlap in the thickness direction T. As a result, the upright portion 82 is brought into close contact with the body side due to the contraction of the inner continuous elastic member 55CI. The upright portion 82 on the inner side in the front-rear direction L is upright. A portion of the standing portion 82 that serves as a starting point for standing up the leg side gathers 80 is supported by the highly rigid absorbent core 31, so that the position of the portion of the standing portion 82 can be stably fixed. Therefore, the upright portion 82 on the inner side in the front-rear direction L can be made easier to stand up than the portion of the upright portion 82 .

Further, the compressed portion, the standing portion, and the inner continuous elastic member 55CI may overlap in the thickness direction T. As a result, a portion of the standing portion 82 that serves as a base point for standing up the leg side gathers 80 is supported by the highly rigid pressing portion of the absorbent core 31, so that the position of the portion of the standing portion 82 is stably fixed. can. Therefore, the upright portion 82 on the inner side in the front-rear direction + can be made easier to stand up than the portion of the upright portion 82 .

In addition, the inner edge 811S of the front-rear fixing portion 811 may be arranged in the low-contraction region LER. Accordingly, since the contraction force in the width direction W is low in the low shrinkage region LER, the absorbent core 31 is less likely to shrink in the width direction W, and the front-rear fixing portion 811 is less likely to move inward in the width direction W. As a result, a space for containing excrement in the width direction W can be secured, and diffusion of excrement beyond the standing portion 82 can be suppressed.

In addition, the inner continuous elastic member 55CI may be arranged 5% to 20% behind the front edge 16F of the side joint portion 16 with respect to the entire length of the absorbent article 1 in the front-rear direction L in the front waist region S1. Thereby, the inner continuous elastic member 55CI can be provided in the region where the depression at the lower end of the abdomen of the wearer is likely to be arranged. Since the recess at the lower end of the wearer's abdomen tends to create a gap between the wearer and the front exterior body 50A, the absorbent core 31 can be easily bent in the front-rear direction L along the recess at the lower end of the wearer's abdomen. can. Therefore, due to the contraction of the inner continuous elastic member 55CI, the region where the inner continuous elastic member 55CI is arranged comes into close contact with the wearer's body (specifically, the depression at the lower end of the abdomen). As a result, it is possible to prevent excrement from reaching the outer side in the front-rear direction L of the upright portion 82 . On the other hand, inside in the front-rear direction L of the inner continuous elastic member 55CI, the absorption core 31 is bent in the front-rear direction, making it relatively easy to separate from the body side. As a result, the erecting portion 82 can be erected from the vicinity of the recess at the lower end of the abdomen, so that the excrement diffusing in the width direction W on the absorbent body 30 can be blocked.

The contractile force of the inner continuous elastic member 55CI overlapping the leg side elastic member 85 in the thickness direction T may be greater than the contractile force of the leg side elastic member 85 . Thereby, the leg side elastic member 85 can be firmly fixed at a position where the leg side elastic member 85 overlaps the inner continuous elastic member 55CI in the thickness direction T. The contractile force of the leg side elastic member 85 allows the erecting portion 82 to be firmly erected.

Note that the stretchable sheet 55CS as the continuous elastic member 55C may be arranged inside the front-rear direction L of the inner edge 811E of the front-rear fixing portion 811. The edge may be located inside the inner edge 811E of the front-rear fixing portion 811 . As a result, the erecting portion 82 can be erected with the inner edge of the stretchable sheet 55CS in the front-rear direction L as a base point, so that the excrement diffusing in the width direction W on the absorber 30 can be blocked. In the region where the stretchable sheet 55CS and the thread-like or string-like overlapping continuous elastic member 55CO overlap in the thickness direction T, the standing portion 82 can be brought into close contact with the body, so that excrement moves in the front-back direction L rather than the standing portion 82. can be prevented from reaching the outside of the

(4) Modifications Next, each modification will be described.

In the absorbent article 1 according to Modification 1, the leg elastic members 75 may be arranged at positions overlapping the continuous elastic members 55C in the thickness direction T not only in the front waist region S1 but also in the rear waist region S2. This makes it easier to fix the leg elastic members 75 in both the front waist region S1 and the rear waist region S2. Therefore, the crotch region S3 can be pulled up to both the front waist region S1 and the rear waist region S2 by the contraction of the leg elastic members 75, and especially in the standing posture, side leakage of excrement caused by the drooping of the crotch region S3 can be suppressed. can be done easily.

In the absorbent article 1 according to Modification 2, the inner continuous elastic member 55CI may be composed of all the continuous elastic members 55C overlapping the absorbent core 31 in the thickness direction T. That is, all the overlapping continuous elastic members 55CO may be arranged inside in the front-rear direction L of the inner edge 811E of the front-rear fixing portion 811 in the front-rear direction L. As a result, the contraction of the inner continuous elastic member 55CI can bring the absorbent core 31 into close contact with the wearer's body, thereby preventing excrement from reaching the outside of the absorbent core 31 in the front-rear direction L. In addition, since the inner continuous elastic member 55CI is arranged inside the inner edge 811E of the front-rear fixing portion 811 in the front-rear direction L, excrement reaches the outside in the front-rear direction L with respect to the standing portion 82. can be further prevented. As a result, it is possible to prevent excrement from diffusing in the width direction W from the outer side in the front-rear direction L of the upright portion 82 .

Accordingly, the descriptions herein are for the purpose of illustration and description, and are not intended to have any limiting meaning with respect to the present invention.

Although the case where the front waist region S1 is the first waist region and the rear waist region S2 is the second waist region has been described above, the present invention is not limited to this. The back waist region S2 may be the first waist region, and the front waist region S1 may be the second waist region. In this case, when the wearer raises the leg in the prone sleeping posture, the leg elastic members 75 arranged in the crotch region S3 are pulled up toward the rear waist region S2. By pulling up the leg elastic member 75, the crotch region S3 is pulled up toward the rear waist region S2. As a result, sagging of the crotch region S3 can be suppressed, and the absorbent core 31 can be brought closer to the wearer's body.

Although the overlapping continuous elastic member 55CO is mentioned above as an example of the continuous elastic member 55C overlapping the leg elastic member 75 in the thickness direction T, this is not restrictive. For example, the continuous elastic member 55C that overlaps the leg elastic member 75 in the thickness direction T may be the continuous elastic member 55C that does not overlap the absorbent core 31 in the thickness direction T. The continuous elastic member 55C overlapping the leg elastic member 75 in the thickness direction T may overlap the absorbent main body 20 (eg, the topsheet 41 and the backsheet 42) in the thickness direction T without overlapping the absorbent core 31. . Alternatively, the continuous elastic member 55</b>C overlapping the leg elastic member 75 in the thickness direction T may not overlap the absorbent main body 20 .

Although the case in which the leg side seat 47 is made of one sheet member has been described above, the present invention is not limited to this. For example, the leg side seat 47 may be composed of a plurality of seat members. For example, the leg side seat 47 on one side in the width direction W and the leg side seat 47 on the other side may be composed of different sheet members. Further, for example, the second portion 472 and the third portion 473 of the leg side seat 47 may be configured by different sheet members. Therefore, the leg side sheet 47 may be composed of a plurality of laminated sheet members.

In the above description, a film may be arranged outside the absorber 30 in the width direction W. For example, in the thickness direction T, a film extending in the width direction W may be arranged between the leg elastic member 75 and the fourth portion 474 . Alternatively, instead of the fourth portion 474, a film may be arranged. As a result, excrement can be prevented from seeping out from the film to the non-skin surface side T2, so leakage of excrement can be suppressed.

Although the case where the low basis weight area LR is 0 has been described above, the present invention is not limited to this. The basis weight of the absorbent material in the low basis weight region LR may be greater than zero. For example, the basis weight of the absorbent material in the low basis weight region LR should be lower than the basis weight of the absorbent material of the absorbent core 31 arranged in the crotch region S3.

Although the case where the continuous elastic member 55C has the inner continuous elastic member 55CI arranged inside in the front-rear direction L from the inner edge 811E of the front-rear fixing portion 811 has been described above, the present invention is not limited to this.
