A pants-type disposable diaper in an embodiment embodying the absorbent article of the present invention will be described with reference to the drawings.
[Boxer pants-type disposable diapers]
As shown in FIG. 1, a pants-type disposable diaper 10 (hereinafter simply referred to as “diaper 10”) is a boxer-pants-type diaper, for example, a front body sheet 10F having a rectangular shape following the shape of the abdomen of a human body. The back body sheet 10R having a rectangular shape, for example, following the back shape of the human body, and the absorbent main body 11 that connects the front body sheet 10F and the back body sheet 10R are provided. In addition, in FIG. 2, the front structure of a boxer underpants type disposable diaper is shown.

  The front body sheet 10F and the back body sheet 10R are joined at the left and right ends in the waistline direction to form a side joint 10J. In addition, the front body sheet 10F and the back body sheet 10R are provided with slits 10S toward the upper end portion at the left and right center portions in the waistline direction at the lower end portions that are located in the crotch of the wearer. A crotch joint 10I is formed around the slit 10S. The joined front body sheet 10F and rear body sheet 10R constitute a waistline portion 10W on the inside, and a waistline opening 10A that surrounds a portion around the waistline of the human body at the upper end portion. Further, left and right ends and lower ends of the front body sheet 10F and the back body sheet 10R, and both sides of the slit 10S are configured as a pair of left and right leg-hole covering portions 10C having a cylindrical shape that covers the thighs of the human body. doing. The pair of leg-hole covering portions 10C constitutes a pair of left and right leg-hole openings 10L having a shape surrounding the crotch portion at the lower end portion.

  The front body sheet 10F and the back body sheet 10R are made of a liquid-impermeable material or a nonwoven fabric formed of a liquid-permeable material. The nonwoven fabric is composed of synthetic fibers formed of a material selected from at least one thermoplastic resin such as polyolefin (polyethylene, polypropylene, etc.), polyester, aliphatic polyamide, and the like. Further, the front body sheet 10F and the back body sheet 10R may be made of a stretchable nonwoven fabric or the like. In the diaper 10, the absorbent main body 11 has a function of absorbing and holding excrement exclusively. Therefore, the front body sheet 10 </ b> F and the back body sheet 10 </ b> R are liquid impermeable materials or liquid permeable materials. Any of these materials may be used.

  In the front body sheet 10F and the back body sheet 10R, an upper elastic member 12U is disposed along the waistline direction in an upper region near the waistline opening 10A in the waistline part 10W. Further, the lower elastic member 12D is disposed along the waistline direction in the lower region located below the upper region. The upper elastic member 12U constitutes a waist gather, and the lower elastic member 12D constitutes a tammy gather. Tammy Gather, together with West Gather, will make the diaper fit and anti-slip effect even better. In addition, the elastic member 12L is also arranged in the leg periphery covering portion 10C along the leg periphery direction to improve the adhesion between the leg periphery covering portion 10C and the thigh portion, and the excrement also suppresses leakage. Yes.

  As shown in FIG. 3, the absorptive main body 11 as a crotch formation part is provided with the top sheet 13 which has liquid permeability, the absorber 14, and the back sheet 15 which has liquid impermeability. The top sheet 13 is disposed on the inner side in contact with the wearer's skin, and the back sheet 15 is disposed on the outer side. And in the diaper 10, it has overlapped in order of the back sheet | seat 15, the absorber 14, and the top sheet | seat 13 from the outer side. In addition, you may arrange | position a nonwoven fabric in the outer side of the back seat | sheet 15 in order to improve a touch feeling.

  The material forming the top sheet 13 is one or more materials selected from, for example, a woven fabric, a non-woven fabric, and a porous film. The top sheet 13 is made of, for example, a non-woven fabric having liquid permeability composed of fibers of thermoplastic resin such as polypropylene, polyethylene, polyester, and nylon and subjected to hydrophilic treatment. . The material for forming the back sheet 15 is, for example, a polyethylene resin film having liquid impermeability. The back sheet 15 has a large number of fine holes in order to ensure air permeability.

  The material which forms the absorber 14 is an absorptive material such as fluff pulp, a superabsorbent polymer, a hydrophilic sheet, for example. The absorber 14 has an elongated band shape so as to straddle the front body sheet 10F and the back body sheet 10R. The absorber 14 may be provided with a depression corresponding to the wearer's neck at the center of both side edges along the longitudinal direction. The absorbent body 14 is wrapped with a core wrap sheet made of nonwoven fabric or tissue, and is disposed and bonded between the top sheet 13 and the back sheet 15.

  As shown in FIGS. 3 and 4, the absorbent main body 11 configured as described above includes a front adhesive region 17 that is bonded to the inner surface of the front body sheet 10F at the front end in the longitudinal direction. In the rear end portion on the opposite side to the portion, a rear adhesive region 18 is provided that is bonded to the inner surface of the rear body sheet 10R. The front adhesive region 17 is disposed in a region substantially corresponding to the wearer's abdomen, and the rear adhesive region 18 is disposed in a region substantially corresponding to the wearer's back and buttocks. Further, a crotch region 19 is formed between the front adhesive region 17 and the rear adhesive region 18. The front adhesive region 17 and the rear adhesive region 18 are bonded to the front body sheet 10F and the back body sheet 10R by an adhesive 33 such as a hot melt adhesive. The crotch region 19 is a non-bonded portion with respect to the front body sheet 10F and the back body sheet 10R.

  Here, the rear adhesive region 18 has a larger area than the front adhesive region 17. The rear side adhesion region 18 in the absorbent main body 11 is a region corresponding to the buttocks, and is a region that holds bulky stool with respect to urine. Therefore, the rear-side adhesive region 18 has a larger area than the front-side adhesive region 17, thereby increasing the adhesive force to the rear body sheet 10R, and the other end portion side of the absorbent main body 11 being peeled from the rear body sheet 10R. Is suppressed.

  Further, the front adhesive region 17 and the rear adhesive region 18 are edge portions adjacent to the crotch region 19 and project in the crotch region 19 at the center in the width direction, and are provided with a crotch adhesive region 21. The both sides of the crotch adhesive region 21 are crotch non-adhesive regions 20. In addition, it is preferable that the front-end | tip part of the crotch adhesion area | region 21 of the front side adhesion | attachment area | region 17 and the front-end | tip part of the crotch adhesion area | region 21 of the back side adhesion | attachment area | region 18 are not connected.

  The diaper 10 configured as described above is worn by inserting a wearer's leg through a pair of leg opening 10L. In the state worn by the wearer, the crotch region 19 of the absorbent main body 11 is exposed from the crotch, and the wearer's crotch is in contact. The crotch region 19 is a crotch non-adhesion region 20 with respect to the front body sheet 10F and the back body sheet 10R. Therefore, the pair of leg hole openings 10L are large, and the wearer can easily put their legs through the leg hole openings 10L. The absorbent main body 11 is bonded to the front body sheet 10F and the back body sheet 10R with an adhesive 33 in the crotch bonding region 21. Therefore, even when the wearer moves the hip joint such as walking or bending and stretching the leg, the crotch region 19 is dragged by the movement of the leg covering portion 10C and the front body sheet 10F and the back body sheet 10R. It becomes difficult to shift. Thereby, it becomes difficult to make a clearance gap between the crotch region 19 in the buttocks of the wearer, and excrement is difficult to leak.

  Moreover, when a sitting posture continues using a wheelchair etc. for a long time, a wearer's body may slide down with respect to seating parts, such as a wheelchair, and the diaper 10 may slide up on the stomach side conversely. . Even in such a case, since the diaper 10 includes the leg periphery covering portion 10C, the lower heel portion of the wearer can be prevented from being exposed and the sitting posture continues for a long time. Even if there is, excrement is difficult to leak from the crotch.

According to the diaper 10 as described above, the effects listed below can be obtained.
(1) The absorptive main body 11 is adhered to the front body sheet 10F and the back body sheet 10R in the crotch adhesion region 21. The crotch adhesive region 21 is narrower than the front adhesive region 17 and the rear adhesive region 18. Therefore, it can suppress that a pair of leg periphery opening part 10L becomes small, and it can suppress that a wearer becomes difficult to put a leg.
(2) The front body sheet 10F and the back body sheet 10R are bonded to each other in the crotch bonding region 21. Therefore, the crotch region 19 is less likely to be displaced with respect to the front body sheet 10F and the back body sheet 10R, and excrement can be prevented from leaking from the neck and the like.
(3) The rear side adhesive region 18 has a larger area than the front side adhesive region 17, and the other end side of the absorbent main body 11 is peeled off from the rear body sheet 10R by increasing the adhesive force to the rear body sheet 10R. This can be suppressed.

[Boxer pants-type disposable diaper manufacturing method]
Below, the manufacturing method of the diaper 10 comprised as mentioned above is demonstrated.
As shown in FIG. 5, a front body sheet body 31 and a back body sheet body 32 are supplied to the production line continuously from each original fabric. The front body sheet body 31 as the front body sheet portion is a continuous sheet body constituting the front body sheet 10F, and is sent out from the original fabric. The back body sheet body 32 as the back body sheet portion is a continuous sheet body constituting the back body sheet 10R, and is sent out from the original fabric. Moreover, the absorptive main body 11 is manufactured by another manufacturing line.

  FIG. 6 is a cross-sectional view for explaining the positions of the first region to the fourth region of the front body sheet body 31 and the rear body sheet body 32. The front body sheet body 31 and the back body sheet body 32 are supplied such that the lower end portions constituting the crotch side end portions of the diaper 10 overlap. In FIG. 6, the left side in the figure is the front body sheet body 31, and the right side is the back body sheet body 32. And here, in the back body sheet body 32 as the first sheet portion, the region where the rear adhesive region 18 of the absorbent main body 11 is adhered by the adhesive 33 is the first region 34A, and the first region 34A. A region including the lower end portion on the crotch side that is continuous with the second region 34B. Further, in the front body sheet body 31 as the second sheet portion, the region where the front adhesive region 17 of the absorbent main body 11 is adhered by the adhesive 33 is the third region 34C, and the crotch which is continuous with the third region 34C A region including the lower end portion on the side is a fourth region 34D.

  As shown in FIG. 7, in the production line shown in FIG. 5, the third region 34 </ b> C and the fourth region 34 </ b> D in the front body sheet body 31 are not folded and are in a straight state, and The second region 34B is folded back to the opposite side of the absorbent main body 11 with respect to the one region 34A. And the 2nd field 34B of sheet body 32 for back body is piled up and down with the 4th field 34D of sheet body 31 for front body, and each lower end part is also arranged. In addition, the lower ends of the second region 34B and the fourth region 34D may partially overlap the first region 34A. In such a state, the front body sheet body 31 and the back body sheet body 32 are conveyed on the production line, and then straddle the boundary 35 between the front body sheet body 31 and the back body sheet body 32. An absorbent main body 11 is arranged.

  Specifically, the absorbent main body 11 has the front body sheet 31 and the back body so that the longitudinal direction is perpendicular to the transport direction of the production line and straddles the boundary portion 35 at the position of the crotch region 19. It arrange | positions on the sheet | seat body 32 for use. At this time, the front adhesive region 17 of the absorbent main body 11 is adhered to the third region 34C of the front body sheet 31 by the adhesive 33, and the rear adhesive region 18 of the absorbent main body 11 is adhered to the adhesive 33. Is adhered to the first region 34A of the back body sheet body 32. At the same time, the crotch adhesive region 21 of the front adhesive region 17 and the rear adhesive region 18 is also bonded to the front body sheet body 31 and the back body sheet body 32 by the adhesive 33.

  Thereafter, the front body sheet body 31 and the back body sheet body 32 are folded back so that the absorbent main body 11 is folded in two. Specifically, the front body sheet body 31 and the back body sheet body 32 are folded back at the boundary portion 35, so that the absorbent body 11 faces the wearer's skin side. Folded in half. The bent portion 29 (see FIG. 4) of the absorbent main body 11 is positioned on the upper side by the inseam dimension from the lower end portions of the front body sheet body 31 and the rear body sheet body 32.

Next, the front body sheet body 31 and the back body sheet body 32 are joined at a portion corresponding to the crotch joint portion 10I by a joining means such as heat seal joining or ultrasonic seal joining. Thereafter, a slit 10 </ b> S is formed in a portion corresponding to the crotch joint portion 10 </ b> I so as to hang down in the crotch direction from the bent portion 29 of the absorbent main body 11.
Next, a portion corresponding to the side joint portion 10J (the outer edge portion of the leg-hole covering portion 10C) is joined by a joining means such as heat seal joining or ultrasonic seal joining. Thereafter, a portion corresponding to the side joint portion 10J is cut by a cutter.
As a result, a waistline opening 10A is formed at the upper end, and a leghole cover 10C and a leghole opening 10L are formed on both sides of the absorbent main body 11.

According to the manufacturing method of the diaper 10 as described above, the effects listed below can be obtained.
(4) In the production line, the absorbent main body 11 is arranged so as to straddle the boundary 35 between the front body sheet body 31 and the back body sheet body 32, and the front body sheet body 31 and the back body sheet body 32. Are bonded almost simultaneously. Therefore, the absorptive main body 11 can be accurately bonded to predetermined positions of the front body sheet body 31 and the rear body sheet body 32. In addition, even after the absorbent main body 11 is bonded, even if the absorbent main body 11 is conveyed at a high speed, the position of the absorbent main body 11 can be suppressed from shifting with respect to the front body sheet body 31 and the rear body sheet body 32.

  (5) The leg-hole covering portion 10C and the leg-hole opening 10L of the diaper 10 can be easily provided only by forming the slit 10S. The crotch dimension, which is the length from the bent portion 29 of the absorbent main body 11 to the leg opening 10L in the diaper 10, is the lower end portion of the second region 34B of the back body sheet body 32 and the front body sheet body 31. By aligning the lower end portion of the fourth region 34D, the length of the overlapping portion of the second region 34B and the fourth region 34D can be obtained.

In addition, the said embodiment can also be suitably changed and implemented as follows.
In the example of FIG. 7, the relationship between the front body sheet body 31 and the back body sheet body 32 may be reversed so that the right side in the figure is the front body sheet body 31 and the left side is the back body sheet body 32. .

  -As shown to Fig.8 (a), 2nd area | region 34B of the sheet | seat body 32 for back body parts is return | folded by the side opposite to the absorptive main body 11 with respect to 1st area | region 34A, The fourth region 34D is also folded back to the opposite side of the absorbent main body 11 with respect to the third region 34C. At this time, in order to secure the length (inseam dimension) of the leg periphery covering portion 10C, the distal end portion of the second region 34B is overlapped with the first region 34A, and the distal end portion of the fourth region 34D is the third region. 34C. In this case, the length of the second region 34B and the fourth region 34D from the folded portion to the tip portion is the crotch dimension of the diaper 10.

As shown in FIG. 8B, the third region 34C and the fourth region 34D of the front body sheet body 31 are straightened without being bent, and the second region 34B of the back body sheet body 32 is It is folded back toward the absorbent main body 11 so as not to overlap the one region 34A. As a result, the second region 34B overlaps the fourth region 34D. In this case, the folded portion of the second region 34 </ b> B needs not to overlap the first region 34 </ b> A bonded to the absorbent main body 11. In this example, the second region 34B and the fourth region 34D overlap, but the lengths of the second region 34B and the fourth region 34D often differ. In such a case, the length of the second region 34B and the fourth region 34D is cut by cutting with a cutter to form the leg opening 10L for the crotch of the diaper 10.
In FIG. 8B, the relationship between the front body sheet body 31 and the back body sheet body 32 is reversed, and the right side in the figure is the front body sheet body 31, and the left side is the back body sheet body 32. Also good.

  As shown in FIG. 8C, the third region 34C and the fourth region 34D of the front body sheet body 31 are not bent and are straightened, and the first region 34A and the first region 34A of the rear body sheet body 32 The two regions 34B may also be straight without being bent. In this case, the second region 34B and the fourth region 34D overlap. The fourth region 34D of the front body sheet body 31 located on the side closer to the absorbent main body 11 is the first region 34A of the rear body sheet body 32 located on the side away from the absorbent main body 11. It is necessary not to overlap. Further, the second region 34B may overlap with the third region 34C. Then, when the front body sheet body 31 and the back body sheet body 32 are overlapped, the second area 34B and the fourth area when the front end of the second area 34B and the front end of the fourth area 34D are aligned. The length of 34D is the length of the crotch of the diaper 10. When the tip of the second region 34B and the tip of the fourth region 34D are not aligned, the length may be adjusted by cutting with a cutter.

  As shown in FIG. 8D, the front body sheet body 31 and the rear body sheet body 32 may be a single sheet body 36 instead of separate sheet bodies. In this case, the left side in the figure is the front body sheet part 36A, and the right side is the back body sheet part 36B. The sheet body 36 includes a front body sheet portion 36A and a back body sheet portion 36B, and is folded twice at the center.
