Description

  The present invention relates to a waistband and an absorbent article. More specifically, the waistband and the absorbent article can be easily exchanged in a posture in a lateral position, can stably fix the absorbent main body, and the excrement of the wearer The present invention relates to a waistband used for an absorbent article that is difficult to leak and an absorbent article using the waistband.

  Conventionally, as a diaper for care, a tape type diaper, a pants type diaper, etc. are known. As the tape-type diaper, for example, a top sheet composed of each part of a front body, a crotch part, and a back body, arranged to cover the surface of the absorber and the absorber, and at least a part of which is made of a liquid-permeable material And a back sheet made of a liquid-impermeable material and arranged to extend from the left and right side edges of the back body, fixing the front and back bodies And a fastening tape for doing this are known.

  And such a diaper is replaced | exchanged suitably, for example, if an example of the replacement | exchange procedure of a tape-type diaper is given, it will replace | exchange as follows. First, after putting the wearer's right side down (right-side position), a new diaper is inserted under the wearer's body (between the wearer and the bed). Next, after returning to the right supine position, that is, making it face up, put the wearer's left side down (left-side-down position), and pull out the opposite side of the diaper that was just inserted. . Next, after the front body of the diaper is addressed to the wearer, the front body and the back body are fixed by attaching a fastening tape disposed on the back body to the front body.

  Although the tape-type diaper can be exchanged by such a procedure, this exchange work has a problem that the burden on the wearer and the exchanger is large. Therefore, there was a need to reduce the replacement work. Such needs were not limited to tape-type diapers, but also to pants-type diapers.

  Therefore, as a diaper that meets the above needs, there is a diaper (absorbent article) that includes an absorbent body and a waistband that is attached to the wearer's stomach and holds the absorbent body in the crotch of the wearer. It has been proposed (see Patent Documents 1 to 3). For this absorbent article, only the absorbent body that collects urine and feces should be replaced as necessary. Once worn (worn), the waistband is removed when taking a bath, for example, but it becomes dirty. Other than can be used without replacement.

  The absorbent article described in Patent Documents 1 to 3 has an advantage that the burden of changing diapers is reduced for both the wearer and the exchanger when the wearer who can freely change the posture is used. . However, the absorbent articles described in Patent Literatures 1 and 2 are still worn in diaper replacement when used by a wearer who does not have freedom of joints due to stiffness and whose posture change is not easy. There is a problem that the burden on the operator and the exchanger is large.

  Thus, a diaper (absorbent article) that is difficult for the wearer and the exchanger to feel the burden even when the wearer cannot easily change his position has been desired. Specifically, since there are many cases where a wearer whose posture change is not easy spends in the lateral position, an absorbent article that can be easily replaced while being in the lateral position has been desired.

  In response to the above requirements, the absorbent article described in Patent Document 3 has an advantage that it can be easily replaced even in the lateral position. However, even with the absorbent article described in Patent Document 3, after the absorbent main body is fixed to the waistband, the absorbent main body may be difficult to be stably fixed to the waistband.

That is, it is understood that modifications and improvements as appropriate to the following embodiments are also within the scope of the present invention based on ordinary knowledge of those skilled in the art without departing from the spirit of the present invention. Should be.

[1] Waistband:
Figure 1 is a plan view showing one embodiment of a c Est band is a plan view of the waistband 10a from the side in contact with the wearer. A waistband 10a shown in FIG. 1 has a strip-shaped nonwoven fabric 11 and a stretchable material 12 attached in a stretched state along the longitudinal direction of the nonwoven fabric 11, and a shrinkage region in which the nonwoven fabric 11 is shrunk by the stretchable material 12. 14 and a belt-like body 17 having a non-shrinkable region 15 other than the shrinkable region 14, a hook material 20 of a mechanical fastener attached to one end in the longitudinal direction of the belt-like body 17, and a longitudinal direction of the belt-like body 17 The engaging part 21 which can be engaged with the hook material 20 located in the other edge part is provided. And the strip | belt-shaped body 17 consists of the ventral part 24 and the back | dorsal part 25 which are divided by the center part of the longitudinal direction, and the central part of the ventral part 24 and the central part of the dorsal part 25 are respectively A non-shrink region 15 is located. And the both ends of the longitudinal direction of an absorptive main body can be each fixed to the non-shrink area | region 15. FIG. In FIG. 1 to FIG. 12, common constituent elements are denoted by the same reference numerals.

When such a waistband is used as a waistband of an absorbent article, it can be easily replaced with the body in the lateral position, and the absorbent main body can be stably fixed, and the excrement of the wearer Can be obtained. That is, the waistband is, the central portion of the central portion and the dorsal portion of the ventral side portion, respectively, since the absorbent body is arranged uncontracted area to be secured, a wearer of the central portion in the longitudinal direction After being applied to one iliac side, it can be worn by engaging both ends on the other iliac side of the wearer. Therefore, it can be easily replaced even in the lateral position. Moreover, since the part which fixes the both ends of the longitudinal direction of an absorptive main body is not shrink | contracted, ie, the wrinkle extended in a transversal direction is not formed in a non-shrink area | region, a wearer is along this wrinkle. It is possible to prevent the excrement from leaking. Furthermore, since the wrinkle is not formed in the non-shrinkable region, the absorbent main body can be stably fixed.

[1-1] Band:
The belt-like body provided in the waistband of the present invention has a belt-like nonwoven fabric and a stretchable material attached in a stretched state along the longitudinal direction of the nonwoven fabric, and a shrinkage region where the nonwoven fabric is shrunk by the stretchable material, And it has a non-shrink area | region other than a shrinkage | contraction area | region. The belt-like body is composed of a ventral part and a dorsal part divided by a central part in the longitudinal direction, and a non-contracted region is located in the central part of the ventral part and the central part of the dorsal part, respectively. is doing.

[1-1-1] Nonwoven fabric:
As the belt-shaped nonwoven fabric, for example, a dry nonwoven fabric or a wet nonwoven fabric made of a thermoplastic resin such as polyethylene, polypropylene, or polyester can be used. Specific examples include spunbond, SMS, and air-through nonwoven fabric. Among these, spunbond can be suitably used because of its high strength. Moreover, since an air through nonwoven fabric is excellent in a touch feeling, it is preferable to use it as a raw material of the surface of a strip.

  Although the width | variety of the transversal direction of a strip | belt-shaped nonwoven fabric can be suitably set with a wearer's body shape etc., it is preferable that it is 30-150 mm, for example, and it is still more preferable that it is 50-100 mm.

[1-1-2] Stretch material:
The stretchable material is attached to the nonwoven fabric in a stretched state along the longitudinal direction. By arranging this stretchable material, it becomes difficult to form a gap around the waist when worn, and urine leakage from around the waist can be prevented. Moreover, the fitting property of a diaper becomes favorable and can prevent the diaper slipping down.

  As the elastic material, the same elastic material as that used in conventional disposable diapers can be suitably used. Specifically, flat rubber made of natural rubber, thread rubber made of elastic yarn of synthetic rubber (urethane rubber, etc.), elastic net, elastic film, elastic foam (urethane foam, etc.) and the like can be mentioned.

  In the case where the elastic material is, for example, a flat rubber made of natural rubber or a thread rubber made of elastic yarn of synthetic rubber, the elastic material is preferably attached at a stretch rate of 120 to 400%, and attached at a stretch rate of 200 to 300%. More preferably. By attaching with an extension rate in such a range, a sufficient stretching force can be applied to the wearer without applying an excessive tightening force.

  Examples of the attaching method of the stretchable material include a hot melt adhesive, other highly fluid adhesives, a heat sealing method such as heat sealing, and a method using welding using ultrasonic waves.

  The band-shaped body has a contracted region in which the nonwoven fabric is contracted by the elastic material and a non-contracted region other than the contracted region, and the non-contracted region is a region where the nonwoven fabric is not contracted. Accordingly, the non-shrinkable region may be a region not provided with the elastic material 12 like the waistband 10a shown in FIG. 1, or the non-shrinkable region 15 of the waistband 10b shown in FIG. After attaching the stretchable material 12 from one end to the other end in the longitudinal direction of the nonwoven fabric, the stretchable material 12 attached at a predetermined position is cut by a cutting roll or the like, and the shrinkage force of the stretchable material 12 is reduced. It may be a region that does not reach the nonwoven fabric.

[1-2] Hook material:
The hook material provided in the waistband of the present invention is attached to one end of the belt-like body in the longitudinal direction, and is a convex member of a mechanical fastener (also referred to as a planar fastener). And this hook material can be fixed by mechanical coupling | bonding with the loop material which is a recessed part material. As the hook material, for example, a material having a large number of protrusions (such as hooks, mushrooms, hooks, etc.) formed on the surface is used.

  Such a hook material is attached to the surface of the base material. Examples of the material of the hook material include polyolefin (polyethylene, polypropylene, etc.), polyester, aliphatic polyamide (nylon (registered trademark)), and others. These thermoplastic resins can be used. In particular, polyethylene and polypropylene can be preferably used.

[1-3] Engagement part:
The engaging part provided in the waistband of the present invention is engageable with the hook member located at the other end in the longitudinal direction of the belt-like body. For example, a front patch made of a loop material can be used as the engaging portion. Moreover, since the hook material mentioned above can be engaged also with the material which has fibrous surfaces, such as a woven fabric, a nonwoven fabric, felt, and a pile, besides a loop material, it consists of these materials as an engaging part. A sheet material may be used.

  There are no particular restrictions on the size and shape of the hook material and the engaging portion. For example, the length of the belt-like body 17 in the short direction, such as the hook material 20 and the engaging portion 21 of the waistband 10a shown in FIG. A rectangular shape having the same length is preferable.

  In the waistband of the present invention, it is preferable that a first mark capable of recognizing the central portion is attached to the central portion in the longitudinal direction of the strip. Such a first mark has an advantage that the positioning of the waistband is facilitated. That is, in order to allow the wearer in the lateral position to wear the waistband, first, the central portion of the waistband in the longitudinal direction is disposed on one side of the wearer's iliac bone. At this time, it may be difficult to determine whether or not the central portion of the waistband in the longitudinal direction is located on one side of the wearer's iliac bone. Therefore, the above-described difficulty can be solved by attaching the first mark.

  The first mark is not particularly limited as long as it becomes a mark of an exchanger. Specifically, a mark such as a line, a point, a character, or a symbol can be used. The first mark may be formed by printing or colored hot-melt coating, may be formed by embossing a belt-like body, or may be affixed with the above shape. Specific examples of the line include a substantially U shape, a substantially V shape, and a straight shape. Specific examples of the point include a semicircle, a circle, an ellipse, a triangle, a quadrangle, and a polygon. Here, the points include those formed uniformly and those formed by gathering small dots such as dots. The waistband 10a shown in FIG. 1 is an example in which a linear first mark 30 is formed by printing in the middle of the longitudinal direction of the strip 17 in parallel with the short direction of the strip 17. The waistband 10f shown in FIG. 9 is an example in which a rectangular first mark 30 is formed by printing in the middle of the longitudinal direction of the strip 17 in parallel with the short direction of the strip 17.

  In the waistband of the present invention, it is preferable that a second mark capable of recognizing the non-shrinkable region is attached to the non-shrinkable region. By such a 2nd mark, there exists an advantage that the position which fixes an absorptive main body can be confirmed easily.

  As the second mark, there is no particular limitation as long as it becomes a mark of an exchanger, but specifically, a mark having a shape such as a line, a point, a character, or a symbol can be used. . Further, the second mark may be formed by printing or colored hot melt coating, or may be formed by embossing the belt-like body as long as the effects of the present invention are exhibited. You may paste things. Examples of the lines and points can be the same as those exemplified in the first mark. The waistband 10a shown in FIG. 1 is an example in which a substantially U-shaped second mark 31 is formed by printing along the outer peripheral edge of the non-shrinkable region 15 as a whole. Moreover, the waistband 10f shown in FIG. 9 is an example in which a semicircular second mark 31 is formed in the non-shrinkable region 15 by printing.

  The waistband of the present invention preferably further includes a covering sheet that can cover the end of the fixed absorbent main body when the end of the absorbent main body is fixed to the non-shrinkable region. When such a covering sheet is provided, for example, when the absorbent main body is fixed to the wearer's clothing side surface, it is possible to prevent the absorbent main body from being caught by something and coming off. Moreover, excrement, such as urine and stool that oozes out from the longitudinal end of the absorbent main body, can be covered. That is, when excrement such as urine and feces is excreted in the absorbent main body, the absorber normally absorbs excrement, but the excrement enters the longitudinal end of the absorbent main body. There is a risk of bleeding from the end. Even in such a case, it is possible to prevent excrement from leaking outside by providing the covering sheet.

  As a covering sheet, a nonwoven fabric, a film, paper, these composite sheets, etc. can be used, for example. Among these, a hydrophobic nonwoven fabric and a bonded product (composite sheet) of a hydrophobic nonwoven fabric and a film are preferable. For example, FIG. 3 is an example which shows the waistband 10c further provided with the coating sheet 35 which can coat | cover the edge part of an absorptive main body, and is the top view seen from the wearer's clothing side surface.

  In addition, the covering sheet may be formed by folding a part of the nonwoven fabric forming the band-shaped body, or may be a sheet in which a sheet different from the band-shaped body is fixed to the band-shaped body.

  When the covering sheet is further provided, it is preferable that a fixing means for fixing the covering sheet to the band-shaped body is disposed between the covering sheet and the band-shaped body. Examples of the fixing means include an adhesive material and a hook-and-loop fastener. When using an adhesive material, it is preferable to arrange the adhesive material on the absorbent main body side. And it is preferable to arrange | position the flat raw material suitable for adhere | attaching an adhesive material, for example, a flat film, on the coating sheet located in the non-adhesion side. Moreover, when using a hook_and_loop | surface fastener, it is preferable to arrange | position the hook material of a hook_and_loop | surface fastener to the absorptive main body side, and to arrange | position the engaging part of a hook_and_loop | surface fastener to the strip | belt-shaped body side. When the reverse is selected, that is, when the hook material is arranged on the band-like body side and the engaging part is arranged on the absorbent main body side, the hook arranged on the band-like body when the absorbent main body is removed from the band-like body This is because the material may hit the wearer and cause discomfort.

  FIG. 3 shows an example of the waistband 10c in which the hook-and-loop fastener engaging portion 27 is disposed on the belt-like body 17 side, that is, the wearer-side surface of the covering sheet 35.

  In the waistband of the present invention, it is preferable that a notch or a slit is formed in the non-shrinkable region from one end in the short direction toward the other end. If wrinkles parallel to the longitudinal direction of the absorbent main body are generated, it may cause leakage and the like, and thus it is preferable to prevent the generation of wrinkles. And in order to prevent the generation | occurrence | production of the said wrinkle, it is preferable to always pull an absorptive main body to a transversal direction, and a non-contraction area | region is extended in the longitudinal direction of a strip | belt-shaped body by forming a notch or a slit ( Widening) is possible. Thus, there is an advantage that wrinkles are less likely to be formed in the absorbent main body fixed to the non-shrinkable region.

  The shape of the notch is not particularly limited, and examples thereof include a substantially V shape, a V shape, a U shape, and a U shape. Moreover, the shape of a slit can mention a straight line, a waveform, etc.

  The length of the notch or slit in the short direction of the strip is not particularly limited, but the longer one can effectively prevent wrinkles generated in the absorbent main body. Specifically, the ratio of the notch or slit length (L2) in the short direction of the strip is 5 to 50% with respect to the short length (L1) of the strip. Is preferable, and it is still more preferable that it is 20 to 40%. If the ratio is less than 5%, the widening effect may not be obtained. On the other hand, if it exceeds 50%, the strength of the belt-like body may be insufficient and breakage may occur.

  For example, the waistband 10a shown in FIG. 1 has a substantially V-shaped notch formed in the non-shrinkable region 15 from one end in the short direction toward the other end. The length L2 of the belt-like body 17 in the short direction is 30 mm, the length L1 of the belt-like body 17 in the short direction is 120 mm, and L2 / L1 = 25%. Moreover, the waistband 10e shown in FIG. 6 is an example in which a linear slit 38 is formed in the non-shrinkable region 15 from one end portion in the short direction toward the other end portion.

  It is preferable that the band-shaped body of the waistband of the present invention has a rupture portion that can break the band-shaped body. Forming the rupture portion in this way has the advantage that it is easy to remove the waistband by rupturing the rupture portion, so that it does not take time to replace the waistband.

  As a fracture | rupture part, a perforation, a junction part, etc. can be mentioned, for example. Here, the joining portion refers to a portion in which a belt-like body is formed from two belt-like pieces, and the belt-like piece is melted and joined by heat sealing or ultrasonic sealing. A joining part can be formed by the method similar to the method for joining the front body and the back body of the conventional underpants type diaper.

  For example, the waistband 10a shown in FIG. 1 is an example in which the joint portion 42 is formed as a breakable portion that can break the belt-like body.

  In the waistband of the present invention, it is preferable that a concave portion or a convex portion is formed on the surface of the band-shaped body that is in contact with the wearer. When such a concave or convex portion is formed, the contact area between the wearer's skin and the waistband is reduced, so that even when worn for a long time, skin troubles such as rash can be prevented. There is an advantage.

  The shape of the recess may be, for example, a circle, an ellipse, a triangle, a quadrangle, a polygon, or a groove. Moreover, a recessed part can be formed by embossing a strip | belt-shaped body. Moreover, the strip | belt-shaped body in which the recessed part was formed can be obtained by overlapping the sheet | seat which has a through-hole on the sheet | seat which does not have a through-hole.

  If the concave and convex portions are surfaces of the belt-like body that are in contact with the wearer, the position to be formed is not particularly limited, but corresponds to the side of the wearer assuming that the wearer is in a lateral position. It is preferable to form near the center in the longitudinal direction of the belt-like body. Forming the recesses or projections in this way has the advantage that skin troubles can be effectively prevented.

  The waistband 10a shown in FIG. 1 is an example in which a large number of circular recesses 43 are formed in the back side portion 24 of the band-like body 17 on the side in contact with the wearer. Further, the waistband 10b shown in FIG. 2 is a surface of the belt-shaped body 17 on the side in contact with the wearer, and a large number of circular recesses 43 are formed near the center and both ends in the longitudinal direction of the belt-shaped body 17. This is an example.

  Examples of the shape of the convex portion include a hemispherical shape, a cylindrical shape, a cubic shape, and a polygonal column shape. In addition, for example, when a columnar body such as a quadrangular column is disposed to form a convex portion, the longitudinal central axis may be disposed parallel to the surface of the belt-shaped body or may be disposed vertically. .

  It is preferable that a plurality of through holes are formed in the belt-like body of the waistband of the present invention. By forming a plurality of through holes, there is an advantage that the breathability of the waistband can be improved. That is, even when worn for a long time, it is difficult to get stuffy, and skin troubles such as scabs can be prevented.

  The position where the through hole is formed is not particularly limited, but is assumed to be formed in the portion corresponding to the side of the wearer, that is, in the vicinity of the center in the longitudinal direction of the belt-like body, assuming that the wearer is in the lateral position. Is preferred. Forming the through hole in this way has an advantage that the air permeability of the waistband can be effectively improved.

  Examples of the shape of the through hole include a circle, an ellipse, a triangle, a quadrangle, and a polygon.

  For example, the waistband 10 a shown in FIG. 1 is an example in which a plurality of circular through holes 44 are formed in the ventral portion 24 of the band-like body 17. The waistband 10b shown in FIG. 2 is an example in which a plurality of circular through-holes 44 are formed in the vicinity of the center and both ends in the longitudinal direction of the band-like body 17.

In the waistband of the present invention (first invention) , a pocket forming sheet is attached to at least one of both ends in the longitudinal direction of the strip, and an opening is formed toward the central portion in the longitudinal direction of the strip. pockets that have formed. When pockets are formed in the belt-like body in this way, there is an advantage that the exchange of the waistband is further facilitated. In other words, in order for the wearer in the lateral position to wear the waistband, first, it is necessary to pass one end of the waistband in the longitudinal direction between the wearer and the bed. At this time, an instrument such as an insertion plate may be used in order to easily pass the gap. Then, when the said pocket is formed, after inserting the one end part of the said instrument in a pocket, there exists an advantage that it becomes easy to let the said one edge part of a waistband pass through the said clearance gap using the said instrument. . In the waistband of the present invention (first invention), it is preferable that a string capable of pulling the strip in the longitudinal direction is attached to at least one of both ends in the longitudinal direction of the strip. When the string is attached in this way, there is an advantage that the exchange of the waistband becomes easier. In other words, in order for the wearer in the lateral position to wear the waistband, first, it is necessary to pass one end of the waistband in the longitudinal direction between the wearer and the bed. Then, after passing the said string through the said clearance gap, there exists an advantage that it becomes easy to let the said one edge part of a waistband pass by pulling the passed string.

  The pocket forming sheet may be the same as the belt-shaped non-woven fabric or may be different. When different ones are used, non-woven fabrics, films, papers and the like that are usually used for sanitary materials can be used in sheet form.

  The pocket forming sheet can be attached to the belt-like body by a method such as an adhesive, heat sealing, ultrasonic sealing, or stitching.

  For example, the waistband 10d shown in FIG. 4 has a pocket-forming sheet 46 attached to the end of the belt-like body 17 on the side where the engaging portion 21 is attached, and is directed toward the center of the belt-like body 17 in the longitudinal direction. This is an example in which a pocket in which an opening 48 is formed is formed. FIG. 5 is a cross-sectional view showing an AA ′ cross section of the waistband 10d shown in FIG. 4, and a gap is formed between the belt-like body 17 and the pocket forming sheet 46, and a pocket is formed. Show.

Waistband of the present invention (second invention), at least one of the longitudinal ends of the strip, string capable of pulling the strip in its longitudinal direction that are attached. When the string is attached in this way, there is an advantage that the exchange of the waistband becomes easier. In other words, in order for the wearer in the lateral position to wear the waistband, first, it is necessary to pass one end of the waistband in the longitudinal direction between the wearer and the bed. Then, after passing the said string through the said clearance gap, there exists an advantage that it becomes easy to let the said one edge part of a waistband pass by pulling the passed string.

  The string is not particularly limited as long as it can pull the belt-like body in the longitudinal direction, and for example, a braided string, a twisted thread, a ribbon, and the like can be used.

  A string can be attached to a strip | belt body by methods, such as an adhesive agent, a heat seal, an ultrasonic seal, and a sewing, for example.

  For example, the waistband 10e shown in FIG. 6 is provided with a string 47 capable of pulling the belt-like body 17 in the longitudinal direction at the end of the belt-like body 17 on the side where the engaging portion 21 is attached. It is an example. FIG. 7 is a cross-sectional view showing a B-B ′ cross section of the waistband 10 e shown in FIG. 6, and shows that a string 47 is attached to the surface of the band-like body 17.

  As for the waistband of this invention, it is preferable that the fixing | fixed part which can fix an absorptive main body is attached to the non-contraction area | region of a strip | belt-shaped body. As the fixing part, for example, the same fixing means as described above can be used. For example, the waistband 10f shown in FIG. 9 is an example in which two hook-and-loop fastener engaging portions 60 are provided on the clothes-side surface of the non-shrinkable region 15 of the belt-like body 17.

Such an absorbent article can be easily replaced in the position in the lateral position, the absorbent main body is stably fixed, and the excrement of the wearer is difficult to leak.

  Moreover, as for the absorbent article of this invention, it is preferable that the at least one edge part of the longitudinal direction of an absorptive main body is detachably fixed to the non-contraction area | region of the waistband of this invention. In this way, if the absorbent main body is detachably fixed to the waistband, it is possible to replace only the absorbent main body. There is an advantage that it does not take time and effort.

  FIG. 9 shows an embodiment of the absorbent article of the present invention. The absorbent article 100 shown in FIG. 9 covers the waistband 10c shown in FIG. 3, the absorbent body 50, and the surface of the absorbent body 50. The absorbent main body 55 includes a top sheet 51 made of a liquid-permeable material and a back sheet 52 made of a liquid-impermeable material. And. And the hook material 26 for absorbent main bodies is attached to the surface by the side of the back seat | sheet 52 in the both ends of the absorbent main body 55. As shown in FIG. Since the belt-like body 17 of the waistband 10 c is made of a nonwoven fabric, the absorbent main body hook material 26 can be engaged with the belt-like body 17. Therefore, the both ends of the longitudinal direction of the absorptive main body 55 are fixed to the non-contraction area | region of the waistband 10c so that attachment or detachment is possible. In addition, the thing similar to the hook material 20 attached to the strip | belt-shaped body 17 can be used suitably for the hook material 26 for absorptive main bodies.

  FIG. 10 is a front view showing a use (wearing) state of the absorbent article 100 shown in FIG. 9. That is, the state is shown in which the other end portion in the longitudinal direction of the absorbent main body 55 is fixed to the non-shrinkable region 15 after the hook material 20 of the waistband 10c and the engaging portion 21 are engaged. As shown in FIG. 10, the absorbent article of the present invention remains in the lateral position because the hook material 20 and the engaging portion 21 of the waistband 10 c are engaged on the side of one side of the iliac of the wearer. Can be easily exchanged from posture.

  Further, the waistband 10c shown in FIG. 10 is provided with a cover sheet 35 that is separate from the band-like body 17, and the cover sheet 35 fixes the end of the absorbent main body 55 to the non-shrinkable region. The end of the fixed absorbent main body 55 can be covered. Thus, when the edge part of an absorptive main body is coat | covered, it can prevent that an absorptive main body gets caught in something and remove | deviates. Moreover, excrement, such as urine and stool that oozes out from the longitudinal end of the absorbent main body, can be covered. FIG. 11 is a cross-sectional view showing a cross section CC ′ of the waistband 10c shown in FIG. 10, and as shown in FIG. It is attached. When the covering sheet 35 is fixed to the absorbent main body 55 by the covering sheet hook material 27, it is possible to prevent the covering sheet 35 from turning over and failing to perform its function.

The absorbent article 101 shown in FIG. 12 covers the waistband 10f shown in FIG. 8, the absorbent body, and the surface of the absorbent body. An absorbent main body 155 having a back sheet made of a liquid-impermeable material, and a top sheet partly made of a liquid-permeable material, and a back sheet made of a liquid-impermeable material. ing.

  Two hook tapes 63 (four in total) are attached to both ends of the absorbent main body 155 so as to extend in the lateral direction of the absorbent main body 155. One surface of the hook tape 63 is provided with an absorbent main body hook material 26 that can be engaged with the engaging portion 60 provided on the band 17 of the waistband 10f. When the absorbent main body hook member 26 and the engaging portion 60 are engaged, the both ends of the absorbent main body 155 are detachably fixed to the non-shrinkable region of the waistband 10f. Further, third marks are formed at both ends of the absorbent main body 155. By forming the third mark, there is an advantage that alignment of both end portions of the absorbent main body 155 is facilitated. As the third mark, a mark having the same shape as the first mark already described above can be formed by the same method.

[2-1] Absorber:
The absorber is a member for absorbing and holding the wearer's urine. The absorber is made of an absorbent material because it needs to absorb and retain the wearer's urine and body fluid.

  Examples of the absorbent material constituting the absorber include conventionally known absorbent materials usually used for disposable diapers and other absorbent articles, such as fluff pulp, super absorbent polymer (Super Absorbent Polymer; hereinafter referred to as “SAP”). And a hydrophilic sheet. It is possible to use wood pulp or non-wood pulp defibrated as fluff pulp, sodium polyacrylate as SAP, tissue, absorbent paper, hydrophilized nonwoven fabric as hydrophilic sheet preferable.

  These absorbent materials are usually used as a single-layer or multi-layer mat. Under the present circumstances, 1 type may be used independently among the said absorptive materials, and 2 or more types may be used together. Especially, what used together about 10-500 mass parts SAP with respect to 100 mass parts of fluff pulp is preferable. At this time, the SAP may be uniformly mixed in each mat of fluff pulp, or may be arranged in layers between the layers of the multilayer fluff pulp.

  It is preferable that the absorber is interposed at least in part between the top sheet and the back sheet. Usually, the absorber is interposed between the top sheet and the back sheet by being sandwiched between the top sheet and the back sheet and sealing the peripheral edge thereof. Therefore, the flap part in which the absorber is not interposed is formed between the top sheet and the back sheet at the peripheral part of the absorber. The absorber is interposed in at least a part between the top sheet and the back sheet. More specifically, the absorbent body is interposed at least in the central portion (inseam portion) in the longitudinal direction of the absorbent main body. In addition, the absorber may be arrange | positioned over the both ends of the longitudinal direction of an absorptive main body.

  It is preferable that the absorber is entirely wrapped with a hydrophilic sheet. Such a configuration has an advantage that SAP can be prevented from leaking from the absorber and shape stability can be imparted to the absorber.

  Although there is no restriction | limiting in particular about the shape of an absorber, The shape used in the conventional disposable diaper and other absorbent articles, for example, a rectangular shape, an hourglass type, a gourd type, a T shape etc. can be mentioned. The absorbent article 100 shown in FIG. 9 is an example in which an hourglass-type absorber is used as the absorber 50.

  In addition, a sheet (second sheet) for diffusing liquid such as urine and body fluid may be incidentally disposed on the surface side of the absorber (for example, between the absorber and the top sheet). . When this second sheet is attached, due to the wearer's posture, etc., even when the space on the back side of the top sheet is not sufficiently formed, the absorption rate of urine, body fluid, etc. is difficult to decrease, and the absorption rate decreases. It is possible to prevent leakage of urine and body fluids.

  Examples of the material constituting the second sheet include hydrophilic and liquid-permeable materials such as woven fabric, non-woven fabric, porous plastic, and fluff pulp. Examples of these constituent materials include polypropylene, polyethylene, polyester, rayon, pulp, and composite fibers thereof. As the pulp, crimped fibers such as curly cellulose fibers can be suitably used.

[2-2] Top sheet:
A top sheet is a sheet | seat arrange | positioned so that the surface (surface of the wearer side at the time of wear) of an absorber may be coat | covered. Since it is necessary for the absorbent body to absorb the wearer's urine, at least a part (all or a part) of the top sheet is made of a liquid-permeable material. Usually, at least near the surface of the absorber, it is made of a liquid-permeable material that can permeate the wearer's urine and body fluid. As long as at least a part is made of the liquid permeable material, the entire top sheet is not necessarily made of the liquid permeable material.

  Examples of the liquid permeable material constituting the top sheet include a woven fabric, a nonwoven fabric, and a porous film. Among these, it is preferable to use a non-woven fabric made of a thermoplastic resin such as polypropylene, polyethylene, polyester, or nylon and subjected to a hydrophilic treatment. There is no restriction | limiting in particular also about the kind of nonwoven fabric, The conventionally well-known nonwoven fabric manufactured by various manufacturing methods, such as air through (card hot air), card | curd embossing, and a spun bond, can be used suitably.

[2-3] Backsheet:
A backsheet is a sheet | seat arrange | positioned so that the back surface (surface of the wearer's clothing side at the time of wear) may be coat | covered. The back sheet is made of a liquid-impermeable material in order to prevent the wearer's urine from leaking outside the diaper.

  Although there is no restriction | limiting in particular about the arrangement | positioning method, For example, the structure which arrange | positions the back seat | sheet 52 so that it may correspond with a top sheet like the absorbent article 100 shown in FIG. 9 is employable. However, it is not always necessary to adopt such a configuration. From the viewpoint of preventing leakage of urine absorbed by the absorber, a back sheet made of a liquid-impermeable material is disposed at least in a portion where the absorber is present. May be.

  Examples of the liquid-impermeable material constituting the back sheet include a liquid-impermeable film made of a resin such as polyethylene. Among these, it is preferable to use a microporous polyethylene film. This microporous polyethylene film has a large number of fine pores of 0.1 to several μm, and is liquid-impermeable but has moisture permeability, so it is possible to prevent stuffiness inside the absorbent article. There is an advantage.

[2-4] Solid gathering:
The absorptive main body of the absorptive article of the present invention may be provided with a three-dimensional gather in order to prevent side leakage of urine excreted by the wearer. The three-dimensional gather is a member for preventing side leakage of the urine excreted by the wearer, and is a leak-proof wall configured to stand up three-dimensionally. By forming such a three-dimensional gather, the three-dimensional gather becomes a breakwater, and leakage from the opening around the leg of the absorbent article or the like (so-called “lateral leakage”) can be effectively prevented.

  The structure of a three-dimensional gather can employ | adopt the structure used for the conventional disposable diaper and other absorbent articles. For example, a material in which a stretchable material for a three-dimensional gather is arranged on a part of the water-repellent sheet material, and a gather (gutter) is formed on the sheet material by the three-dimensional gathered elastic material can be suitably used.

  The three-dimensional gather may be formed of a sheet material that is completely different from the top sheet or the back sheet, but may be formed by folding the top sheet or the like.

  In order to prevent leakage from the crotch part, this three-dimensional gather may be formed at least in the center part (inseam part) in the longitudinal direction of the absorbent main body, but extends over both ends in the longitudinal direction of the absorbent main body. It may be formed. For example, the absorbent article 100 shown in FIG. 9 has a pair of three-dimensional gathers 57 continuously formed from one end to the other end in the longitudinal direction along the longitudinal direction. This is an example in which a three-dimensional gather elastic material 58 is provided at the tip. Note that at least one pair of solid gathers must be formed, but two or more pairs may be formed.

  The three-dimensional gather may be an inward gather that tilts toward the inside of the absorbent article, or may be an outward gather that tilts toward the outside of the absorbent article. Further, a three-dimensional gather (a so-called C-fold gather, Z-fold gather, or the like) in which a bent portion or a folded portion is formed in a part of the height direction can also be used.

[2-5] Leg elastics:
In the absorbent main body of the absorbent article of the present invention, it is preferable to arrange an elastic material for the leg periphery at a site corresponding to the leg periphery. By arranging the leg-stretchable material, a gather (leg gather) rich in stretchability can be formed in the leg-surrounding opening. Therefore, it is difficult to form a gap around the leg, and urine leakage from the opening around the leg can be effectively prevented. Further, when the leg stretchable material is disposed, the leg stretchable material contracts on both sides of the absorbent body when the absorbent article is replaced, so that the vicinity of the crotch portion is deformed into a bowl shape and a recess is formed. For this reason, urine and a bodily fluid accumulate in the crevice, and exchange of an absorptive article can be performed easily, without spilling a urine and a bodily fluid.

  As the leg-surrounding stretchable material, the same stretchable material as the above-described waistband belt can be used in the same manner.

  For example, the absorbent article 100 shown in FIG. 9 is an example in which leg gathers are formed by arranging two leg-stretchable elastic members 59 made of thread rubber linearly along the longitudinal direction of the absorbent main body 55. . In addition, it is not necessary to arrange | position the leg periphery elastic material linearly, for example, you may arrange | position in a curve along the curve of the leg periphery opening part of an absorptive main body.

  In the absorbent article of the present invention, the absorbent main body may be fixed to the surface (contact surface) with which the wearer of the waistband contacts, or the absorbent main body on the clothing side surface (clothing surface) of the wearer. May be fixed. If it fixes to a contact surface, exchange is easy, and if it fixes to a clothing surface, it can prevent that an absorptive main body will come off easily when it catches on something.

[3] Method of wearing absorbent article:
The absorbent article of the present invention can be suitably used for a wearer whose posture change is not easy. An example of the wearing procedure will be described below for a wearer whose posture change is not easy, in order to perform the exchange while keeping the lateral position. First, it arrange | positions so that the surface of the side which touches the wearer of a waistband may become an upper surface. Next, the end of the waistband on the side where the absorbent main body is not fixed is passed between one side of the wearer and the sheet. At this time, if the waistband 10d shown in FIG. 4 or the waistband 10e shown in FIG. 6 is used, the end portion can be easily passed.

  Next, the end of the waistband passed between the wearer's flank and the sheet is pulled until the first mark attached to the band of the waistband is located near the wearer's flank. Next, the both ends of the waistband are engaged with the other side of the wearer. Next, after moving the waistband engaged with both ends to the ventral side, the absorbent main body is passed through the wearer's crotch, and the end of the absorbent main body is fixed to the non-contracted region of the waistband. Then, the edge part of an absorptive main body is coat | covered with a coating sheet. In this way, the wearer can wear the absorbent article of the present invention.

[4] Method for manufacturing absorbent article:
The manufacturing method of the absorbent article of this invention is demonstrated and illustrated about the case where the absorbent article 101 shown in FIG. 12 is manufactured.

  First, the waistband 10f is manufactured. In order to manufacture the waistband 10f, first, a long nonwoven fabric is prepared. Next, a hot melt adhesive is applied to a boundary portion including a boundary line located closest to one end portion of the nonwoven fabric in the lateral direction when the nonwoven fabric is divided into four equal parts in the lateral direction. At this time, hot melt adhesion is not applied to the portion that becomes the non-shrinkable region 15. Next, the stretchable material 12 is disposed in the stretched state along the longitudinal direction of the nonwoven fabric on the one end portion side of the nonwoven fabric. Next, with the central axis in the longitudinal direction of the nonwoven fabric as a base point, the other end side portion in the short direction of the nonwoven fabric is folded and overlapped with the one end side portion on which the stretchable material 12 is disposed. To obtain a strip-like body. Specifically, the width of the obtained strip-shaped body is preferably 120 mm.

  Next, of the obtained strip-shaped body, a portion to which the hot melt adhesive is not applied, that is, a portion that becomes the non-shrink region 15 is subjected to pressure and heat treatment with an embossing roll. The elastic material 12 of the part which becomes becomes cut. In this way, a non-shrinkable region 15 is formed to obtain a long belt-like body in which the stretchable material 12 is interposed between two nonwoven fabrics.

  Next, a nonwoven fabric provided with holes in advance is bonded to one surface of the obtained long band-shaped body (the surface on the wearer side of the waistband 10f). Next, a plurality of linear marks (first marks 30) are printed on the one surface of the long band by an ink jet printer, and a semicircle mark (second mark) is printed on the other surface of the long band. A plurality of marks 31) are printed. Next, a rectangular engagement portion 60 is attached to both sides of the second mark 31 on the other surface of the long band-shaped body (the surface on the clothing side of the waistband 10f).

  Next, the rectangular hook member 20 is attached about 5 mm downstream from the intermediate position of the adjacent ones of the plurality of first marks 30 provided on the one surface of the long belt-like body. Next, at a position about 5 mm upstream from the middle of the first mark 30 provided on the one surface of the long belt-like body, a rectangular engagement portion 21 is formed on the other surface of the long belt-like body. Is attached.

  Next, a substantially triangular shape (substantially V-shaped) at the bottom at the same position as the second mark 31 provided on the one surface of the long band-shaped body, that is, the same position in the longitudinal direction of the long band-shaped body. Make a notch. This incision is formed on the edge side opposite to the central axis that becomes the base point when the nonwoven fabric is folded, and has a height of 30 mm from the edge (length in the short direction of the long band-shaped body), 20 mm This is the bottom side (length in the longitudinal direction of the long belt-like body).

  Next, the long band-shaped body is cut at a portion of the distance between the engaging portion 21 and the hook member 20 that has a shorter distance to obtain the band-shaped body 17.

  Note that the assembly order of the waistband 10f does not have to be the order described above, and may be before or after.

  Next, the absorbent main body 155 is manufactured. In order to manufacture the absorbent main body 155, first, a long backsheet as a material for the backsheet is prepared. Next, an absorbent body wrapped in a hydrophilic sheet is laminated on the surface of the long backsheet, and leg-stretchable materials are disposed on both sides of the absorbent body. Next, a long sheet material, which is a material for the top sheet, is laminated so as to cover the absorber to obtain a long laminated body.

  Next, a long water-repellent sheet material for three-dimensional gathers is attached with one end folded back and two stretchable members for three-dimensional gathers sandwiched between the two, and the long water-repellent sheet. Get the material. Next, the obtained long water-repellent sheet material is disposed on both sides of the absorbent body of the long laminate with the three-dimensional gather elastic material inside, and then fixed to the top sheet.

  Next, the portion extending outward from the back sheet is folded back and fixed to the back side of the back sheet to form a long absorbent main body. Next, hook tape 63 for fixing to the waistband 10f is attached to the long absorbent main body to obtain a long absorbent main body with a hook. The hook tape 63 is obtained by attaching an absorbent main body hook material to a tape-like base material, and is provided at four locations on both sides of both ends in the longitudinal direction of the absorbent main body. The hook tape 63 is preferably folded and temporarily fixed to the inside, that is, the three-dimensional gather sheet side, in order to prevent troubles such as being caught in the processing machine. Next, the obtained long absorptive main body with a hook is cut | disconnected between each absorber, and the absorptive main body 55 is obtained.

  In addition, the 3rd mark 62 can be previously printed on the back sheet at intervals equal in length in the longitudinal direction. When this third mark is provided, alignment with the second mark 31 is facilitated, and when the long absorbent main body with the hook is cut, the third mark 62 is used as a mark to cut at that position. Can be cut easily.

  After manufacturing the waistband 10f and the absorbent main body 155 as described above, by fixing one end or both ends in the longitudinal direction of the absorbent main body 155 to the non-shrinkable region 15 of the waistband 10f, The absorbent article of this invention can be manufactured.
