  FIG. 1 is a view of a sanitary napkin according to the present invention, as viewed from the skin side, which is a wearing surface of a wing type sanitary napkin provided with a wing mechanism provided to be fixed to underwear such as shorts. For convenience of explanation, the sanitary napkin is extended in FIG. 3 shows a cross section AB in the horizontal direction of FIG. 1, and FIG. 5 shows a section between the vertical cross sections CD in FIG. In the sanitary napkin 2, the liquid-permeable surface sheet 5 that allows the body fluid that directly hits the skin to permeate and the absorbent body 4 that absorbs the body fluid discharged from the body such as menstrual blood and the underwear such as shorts are usually faced. The three-stage structure of the liquid-impermeable back sheet 3 is fixed. Further, standing gathers 7 are provided at both ends of the sanitary napkin 2 toward the skin side to prevent side leakage of body fluid such as menstrual blood. A description of the elastic member constituting the sanitary napkin 2 and a detailed description of the material of the liquid permeable top sheet 5, the absorber 4, and the liquid impermeable back sheet 3 are omitted. In the present invention, from the viewpoint of convenience, the surface in contact with the human skin is referred to as the sanitary napkin surface side, and the surface in contact with underwear such as shorts is referred to as the sanitary napkin back surface side. The part excluding the wing part 6 is called a sanitary napkin body.

  The shape of the outer periphery of the liquid-impermeable back sheet 3, which is the back side of the sanitary napkin 2, forms a round around the outer periphery including the napkin body portion and the wing portion 6 as shown in FIG. 1. An absorbent body 4 is provided on the liquid-impermeable back sheet 3, and the shape of the absorbent body 4 is smaller than the napkin 2 of the main body, and is provided inside the napkin main body. The width of the absorbent body 4 extends to the outer ends of the standing gathers 7 provided on the left and right on the sanitary napkin 2. The front and rear lengths of the absorber 4 are shorter than the liquid-permeable surface sheet 5 and are indicated by broken lines in FIG. The liquid permeable surface sheet 5 is provided on the absorber 4, and the outer peripheral shape of the liquid permeable surface sheet 5 is the same as the outer peripheral shape of the liquid impermeable back sheet 3. Standing gathers 7 are provided at two left and right positions on the liquid-permeable back sheet 5. The shape of the standing gather 7 is elongated in the vertical direction from the front end to the rear end of the main body napkin, and the gather mechanism 7 has a gather function by folding a piece of gathered fabric into a plurality of layers. ing. In the wing type sanitary napkin equipped with a general wing mechanism 6, an adhesive is provided on the surface of the liquid-impermeable back sheet 3 facing the underwear such as shorts for the purpose of fixing to the skin side of the underwear such as shorts. It has been applied. With this adhesive, the sanitary napkin 2 is fixed to the skin side of underwear such as shorts so that the sanitary napkin 2 does not shift. Further, the wing type sanitary napkin provided with the wing mechanism 6 is provided with trapezoidal wing portions 6 provided at the left and right ends of the sanitary napkin main body. The function of the wing portion 6 is that when the body of the sanitary napkin is fixed to the skin side of the underwear such as shorts, the wing portion 6 is folded back so as to sandwich the underwear such as shorts and is applied to the wing portion 6 facing the underwear such as shorts. It is fixed to underwear such as shorts with an agent. A pair of compressed grooves are provided on the left and right sides of the napkin main body in the longitudinal direction, that is, in the longitudinal direction, and are formed in an elliptical shape at the abdomen end and the buttocks end. In the description of the present invention, this compressed groove is referred to as a first compressed groove 10 for convenience.

  A first embodiment will be described with reference to FIGS. The 1st pressing groove 10 is provided in the right-and-left both-sides edge part of the sanitary napkin main body 2 with the 1st pressing groove 10 compressed toward the absorber from the body fluid-permeable surface sheet in the length direction, respectively. ing. When a sanitary napkin 2 is worn by a woman, the center is sandwiched between first compressed grooves 10 provided on both side edges of the sanitary napkin, which are provided with a wing mechanism 6 when the sanitary napkin 2 is viewed from the vertical direction. In the vertical direction, the female local part, which is the excretory organ, is facing. The 2nd pressing groove | channel 11 squeezed toward the absorber 4 from the bodily fluid permeable surface sheet 5 is provided so that the longitudinal direction of this female part may be followed. The length of the second compressed groove 11 in the vertical direction is the approximate length in the female local vertical direction facing each other. The front and rear ends of the second compressed groove 11 are the ends of the second compressed groove 11, and the two front and rear ends of the second compressed groove 11 are semi-elliptical body fluid-permeability. The 3rd pressing groove | channel 12 squeezed toward the absorber 4 from the surface sheet 5 is provided. The ventral front end of the second compressed groove 12 is open to the abdomen so as to follow the first compressed groove 10 provided on the left and right sides of the sanitary napkin 2. On the other hand, the rear end of the second compressed groove 11 is open to the rear side along the first compressed groove 10. The groove width of both the second pressing groove 11 and the third pressing groove 12 is set in the range of 0.1 mm to 2 mm. The set value is determined by the intended use of the wearer. In FIG. 2, each pressing groove 8 of the 1st pressing groove, the 2nd pressing groove, the 3rd pressing groove, and the 4th pressing groove is shown with sectional drawing. In FIG. 2, it is a pressing groove | channel of the state which extended the sanitary napkin 2 flatly before mounting | wearing with a body. When the sanitary napkin 2 is attached to the body and the sanitary napkin 2 is bent in accordance with the body, the width of the groove is narrowed so that the groove portion of the compressed groove 8 is crushed.

  Next, the effect | action and effect of the 2nd pressing groove 11 are demonstrated. As shown in the cross-sectional view of the sanitary napkin shown in FIG. 1 when stretched flat, the first compressed groove, the second compressed groove, the third compressed groove, and the fourth compressed groove are body fluids. It is squeezed toward the absorber 4 from the liquid-permeable surface sheet 5, and as shown in FIG. The valley is U-shaped. In general, when wearing underwear such as shorts, the shape is elliptical when viewed from above the shorts, but the shape changes depending on behavior changes such as standing, sitting and walking. Even if a woman wears a sanitary napkin 2 in underwear such as shorts during menstruation, and wears underwear such as shorts on the same, the same tendency occurs. In the sanitary napkin 2 provided with the conventional 1st pressing groove 10, the 1st pressing groove 10 compressed in the right and left on the front-side body fluid-permeable surface sheet 5 of the sanitary napkin 2 is provided, and 1st pressing is carried out. By narrowing the width of the groove 10, the sanitary napkin 2 is easily bent to improve adhesion and prevent menstrual leakage. A woman wearing the sanitary napkin 2 is not always in the same posture, and changes in behavior are constantly remarkable, standing, sitting, walking. At this time, it is difficult to follow with only the first compressed groove 10, and twisting occurs at the central portion with the lapse of wearing time and wrinkles occur. If unnecessary wrinkles occur around the female local area, which is a menstrual discharge organ, a gap is created by the wrinkles, and the discharged menstrual blood may follow the gap between the wrinkles and cause a menstrual leak. In addition, the wrinkles near the center of the sanitary napkin 2 are liable to cause lateral displacement of the sanitary napkin, and may cause menstrual leakage from the sanitary napkin 2. It is difficult to deal with everything with the conventional first compressed groove 10 alone. The second compressed groove 11 of the present invention focuses on the vicinity of the center where the female local part which is a menstrual discharge organ directly faces. The 2nd pressing groove 11 compressed toward the absorber 4 from the bodily fluid permeable surface sheet 5 is provided so that the longitudinal direction of a female part may be followed, and the length of the vertical direction of this 2nd pressing groove 11 is set. The length of the women's local area facing each other is the approximate length. By setting the width of the second compressed groove 11 within a range of 0.1 mm to 2 mm, the second compressed groove 11 can have a U-shaped valley like the first compressed groove 10. The center of the sanitary napkin 2 is formed by forming a situation where the U-shaped valley of the second compressed groove 11 is narrowed and is easily bent even in the region sandwiched between the first compressed grooves 10 on the left and right. By forming an escape path between the body fluid-permeable topsheet 5 and the absorbent body 4 in a part, the sanitary napkin 2 can be easily formed into an elliptical shape that forms an arc between the lateral directions A-B of the sanitary napkin 2 as shown in FIG. Can create a state. As shown in FIG. 3, if the state between the lateral directions A and B of the sanitary napkin 2 can be easily formed in an elliptical shape that forms an arc, the sanitary napkin is accompanied with a change in the behavior of the woman wearing the sanitary napkin 2. The structure can follow any elliptical shape between the two lateral directions A-B. By this effect, the close contact with the female local area in the vicinity of the center of the sanitary napkin 2 is enhanced, and the prevention of menstrual blood leakage can be improved.

  Next, the effect and action of the third compressed groove 12 will be described. The 3rd pressing groove 12 provided in the ventral front end of the 2nd pressing groove 11 as an example is demonstrated. Drawing 4 is a figure explaining the operation and effect of the 2nd pressing groove and the 3rd pressing groove in the abdomen side when a woman wears a sanitary napkin. As shown in FIG. 4, the third compressed groove 12 is compressed toward the absorbent body 4 from the body fluid-permeable surface sheet 5 that is semi-elliptical with the end of the ventral front end of the second compressed groove 11 as a base point. A third compressed groove 12 is provided. The 3rd pressing groove 12 is made into the form opened to the abdominal part side so that the 1st pressing groove 10 provided in the front side right and left of the sanitary napkin 2 might be followed. The width | variety of the groove | channel of the 3rd pressing groove 12 is set in the range of 0.1 mm-2 mm. The set value is determined by the intended use of the wearer.

  An example will be described in which a woman wearing a sanitary napkin walks with a large change in behavior. When starting to walk, the skin is slightly curved and twisted between the legs that have been raised before and the legs that have not been raised, that is, the crotch area. When the right foot comes out, the skin is slightly bent and twisted in the crotch area, and when the left foot comes out, the skin is bent and twisted slightly to the left. This happens alternately when walking. The sanitary napkin 2 is thicker than fabric made of cloth such as shorts and is less flexible than a single cloth. In this way, when walking continues, wrinkles are naturally generated to follow the surface of the sanitary napkin 2 in contact with the skin. The wrinkles vary depending on the wearer's situation or wearing condition of the sanitary napkin 2. When unnecessary wrinkles occur, gaps are created by the wrinkles, and menstrual blood discharged from the female local area follows the wrinkle gaps to cause menstrual leakage. In addition, unnecessary wrinkles of the sanitary napkin cause lateral displacement of the sanitary napkin 2, which also causes menstrual leakage. The third pressing groove 12 of the present invention focuses on what force is generated on the surface of the sanitary napkin 2 having poor flexibility when the skin is curved by walking or the like. FIG. 4 shows a state in which a woman wearing the sanitary napkin 2 walks out of the right foot when walking, and the physiology of the present invention when the right foot moves forward and the skin is slightly curved in the arrow direction K is twisted. Explains the action of the napkin. The third pressing groove 12 has a valley corresponding to the amount compressed from the body fluid-permeable surface sheet 5 toward the absorber 4. The valley is U-shaped. When walking and twisting the crotch slightly, the center of the crotch is the largest and weakens as it moves away from the foot. In the present invention, by providing the second pressing groove 11 and the third pressing groove 12, it can be divided into three as shown in FIG. These areas are called G area, H area, and J area. When the skin is slightly bent and twisted in the arrow direction K, the G section is twisted the most, and the U-shaped groove of the third compressed groove 12 at the boundary with the H section facing the third compressed groove 12 Compression and middle breakage can occur and a buffering effect can be obtained. At the same time, in the third compressed groove 12 at the boundary between the H section and the J section, compression and folding occur in the U-shaped groove in the same manner, but it is weaker than the compression of the third compressed groove where the G section and the H section are in contact. Become. It is intentionally divided into three by the third compressed groove 12 and absorbs the compressive force in the U-shaped groove of the third compressed groove 12, and plays a role of a buffering effect that supports in the H area and the J area. . Therefore, the G section is most twisted and becomes weaker from the H section to the J section. By intentionally providing the U-shaped groove of the third compressed groove, unnecessary wrinkles can be suppressed on the surface of the sanitary napkin 2 even if the skin is slightly curved and twisted in the arrow direction K, and is unnecessary. The effect of preventing menstrual leakage due to gaps caused by wrinkles and the lateral displacement of sanitary napkins can be obtained. In the case of the left foot, the situation is exactly the reverse, and the G section described above is replaced with the J section and the J section is replaced with the G section.

  A second embodiment will be described with reference to FIGS. The wing-type sanitary napkin 2 shown in FIG. 1 is provided with a wing portion 6 having a trapezoidal shape provided at both left and right ends of the sanitary napkin main body. The trapezoidal shape of the wing portion 6 is such that the outer vertical direction is a straight line parallel to the sanitary napkin body, but the wing portion 6 is shorter than the vertical distance in contact with the napkin body. . The wing portion 6 is in contact with the napkin main body in a straight line obliquely outward from the front and rear ends in the longitudinal direction. The point i on the extension line of the front and rear ends of the wing portion 6 that is obliquely cut at both front and rear ends of the wing portion 6 is in contact with the body fluid-permeable surface sheet 5 of the sanitary napkin 2. The wing part 6 is located on the left and right of the sanitary napkin 2 and the front and back of the wing part 6 extends to contact the body fluid-permeable surface sheet 5 at a total of four points, two on the left and right on the abdomen and two on the left and right on the buttocks. There are i points. The left and right i points located on the abdomen side are connected to each other by a curved line that draws an arc on the outside, and a fourth squeezing groove that is squeezed from the body fluid-permeable surface sheet 5 toward the absorber 4 is provided. Also on the butt side, i points at two places on the right and left sides of the butt side are connected by an arc-shaped curve on the outer side, and a fourth squeezed groove 13 squeezed from the body fluid-permeable surface sheet 5 toward the absorber 4 is provided. The width | variety of the groove | channel of the 4th pressing groove 13 is set to 0.1 mm-2 mm, and it determines with a wearer's use application regarding a setting value. The shape of the groove of the fourth pressing groove 13 is a U-shaped valley as shown in FIG.

Next, the operation and effect of the second embodiment will be described. FIG. 5 is a cross-sectional view taken along the line CD in FIG. FIG. 5 is a diagram assuming that the sanitary napkin 2 is worn by a woman. The fourth compressed groove 13 serves as a half-fold function with the fourth compressed groove 13 as a boundary, and the sanitary napkin is divided into three parts at the front middle part and the rear part as shown in a cross-sectional view between CDs. It becomes.
There are undulations before and after the local area of the woman facing the sanitary napkin 2. The napkin 2 is divided into three parts, the front middle part and the rear part, so that each sanitary napkin 2 corresponds to the undulations of the body facing each other. Further, the crotch portion of the body on which the sanitary napkin 2 is worn by a woman draws an arc, and the sanitary napkin 2 itself forms an arc in accordance with the body by dividing the sanitary napkin 2 into the front middle part and the rear part. It has a form like this. A woman wearing the sanitary napkin 2 is not always in the same posture, and changes in behavior are constantly remarkable, standing, sitting, walking. When the sanitary napkin 2 is worn, the shape between the CDs becomes elliptical, but the shape change is likely to change with the action of the woman. As the wearing time elapses, wrinkles are generated on the sanitary napkin to cope with the change in shape. If the load on the sanitary napkin 2 can be received and the wrinkle generation point can be suppressed or induced by intentionally forming a structure divided into three at the front middle part and rear part by the fourth compressed groove of the present invention, it is not possible. The menstrual blood that has been discharged due to the necessary wrinkles can suppress leakage of menstrual blood that occurs through the gaps of the wrinkles. In addition, the sanitary napkin 2 is less likely to be displaced due to unnecessary wrinkles of the sanitary napkin 2, and menstrual leakage that accompanies the displacement of the sanitary napkin can be suppressed.

  The present invention is used in the industry for manufacturing sanitary napkins.
