In Patent Document 1, a thread-like elastic material is exemplified as the waist elastic material, but by using an elastic sheet instead, the front body exterior body and the back body exterior body (girth part) can be worn on the surface. Can be adhered to. Therefore, it is possible to make it difficult for the traces of the stretchable material to remain.

However, after fixing the stretchable sheet to the non-stretchable sheet in the stretched state, if the end of the stretchable sheet is not fixed to the non-stretchable sheet, the end of the stretchable sheet may be turned over. This is because, for example, in a production line, even if tension is applied to the stretchable sheet between the transport rollers and the stretchable sheet is transported while being stretched, there is a slight difference in how tension is applied depending on the position from the transport roller. It is considered that the stretchable sheet shrinks locally and turns over. It is also considered that the elastic sheet is easily turned over when the elastic sheet is expanded and returned in the width direction intersecting the stretching direction of the elastic sheet.

In particular, when the end of the elastic sheet on the waistline opening side (waist opening side) is turned up and folded back, the elastic force increases by the amount of the folded back elastic sheet. As a result, the elastic force around the waist becomes larger than the designed force, and it becomes difficult to widen the waist opening when worn.

The present invention has been made in view of the above-described conventional problems, and an object thereof is pants in which unintentional curling of an end portion of a stretchable sheet provided in a waistline portion on the waistline opening side is suppressed. A type absorbent article is provided.

Hereinafter, as a pants-type absorbent article according to the present invention, an embodiment will be described by taking a disposable diaper for infants as an example. However, the pants-type absorbent article according to the present invention can be used not only as a disposable diaper for infants but also as a disposable diaper for adults, a sanitary shorts, and the like.

=== Configuration of pants-type disposable diaper 1 ===
FIG. 1 is a perspective view of a pants-type disposable diaper 1 (hereinafter, “diaper”). FIG. 2 is a plan view of the diaper 1 in the expanded and expanded state. FIG. 3 is a sectional view taken along line II of FIG.

In the pants-type state shown in FIG. 1, the diaper 1 has a vertical direction and a horizontal direction, and has a waistline opening BH and a pair of leg openings LH. In the vertical direction, the waistline opening BH side is the upper side and the crotch side is the lower side. In addition, as shown in FIG. 3, the direction in which the materials that make up the diaper 1 are stacked is referred to as the thickness direction, the side in contact with the wearer in the thickness direction is referred to as the skin side, and the side that does not contact the wearer is referred to. It is called the non-skin side.

In addition, the diaper 1 has an absorbent main body 10, an abdominal waistline portion 20, and a back waistline portion 30, which are three members having a rectangular shape in plan view. The abdominal girth 20 is applied to the wearer's abdomen, and the back girth 30 is applied to the wearer's back.

In the unfolded diaper 1 shown in FIG. 2, the ventral waistline portion 20 and the back waistline portion 30 are arranged such that their longitudinal directions are along the left-right direction of the diaper 1. The end of the absorbent main body 10 on one side in the longitudinal direction is arranged in the center of the abdominal waistline portion 20 in the left-right direction, and the length of the absorbent main body 10 is long in the center of the back waistline portion 30 in the left-right direction. The other end in the direction is arranged.

In the unfolded diaper 1 shown in FIG. 2, the absorbent main body 10 is folded in two at approximately the center in the longitudinal direction so that the longitudinal direction of the absorbent main body 10 is along the vertical direction of the diaper 1, and the absorbent main body 10 is in the left-right direction. Both side ends of the abdominal waistline portion 20 and both side ends of the back side waistline portion 30 are joined by heat welding, ultrasonic welding, or the like to form a pair of joint regions 2 and thus are shown in FIG. It is a pants-type diaper 1.

As shown in FIG. 3, the absorbent main body 10 includes an absorbent body 11, a liquid-permeable topsheet 12 arranged on the skin side of the absorbent body 11, and a non-skin side of the absorbent body 11. The liquid impermeable back sheet 13 and the exterior sheet 14 arranged on the non-skin side of the back sheet 13.

The absorbent body 11 has an absorbent core 11A that absorbs and holds excreted liquid such as urine, and a liquid-permeable core wrap sheet 11B that covers the absorbent core 11A. Examples of the absorbent core 11A include liquid absorbent fibers such as pulp containing a super absorbent polymer (SAP) formed into a predetermined shape.

As shown in FIG. 2, leg elastic members 15 are provided on both sides of the absorbent main body 10 in the left-right direction, and the diaper 1 fits around the legs of the wearer. The leg elastic members 15 are fixed in an elongated state in the longitudinal direction of the absorbent main body 10, for example, between the exterior sheets 14 that are folded back in the left-right direction to form two layers. Examples of the leg elastic member 15 include a thread-like elastic member and a stretchable sheet.

As shown in FIG. 3, the abdominal waistline portion 20 and the back waistline portion 30 respectively include inner layer sheets 21 and 31, outer layer sheets 22 and 32 laminated on the inner layer sheets 21 and 31, and a plurality of thread-shaped elastic members. 23 and 33.

The outer layer sheets 22 and 32 are arranged on the non-skin side of the inner layer sheets 21 and 31. The inner layer sheets 21 and 31 and the outer layer sheets 22 and 32 are arranged on the non-skin side of the absorbent main body 10. However, the upper end portions 221 and 321 of the outer layer sheets 22 and 32 are folded back to cover the longitudinal end portions of the absorbent main body 10 from the skin side.

The inner layer sheets 21 and 31 and the outer layer sheets 22 and 32 alone are non-stretchable sheets that do not substantially have stretchability in the left-right direction of the diaper 1. As the inner layer sheets 21 and 31 and the outer layer sheets 22 and 32, use SMS non-woven fabric (spun bond/melt blown/spun bond non-woven fabric), spun bond non-woven fabric, air-through non-woven fabric, plastic sheet, perforated plastic sheet, and laminated sheets thereof. You can

The plurality of thread-like elastic members 23, 33 are arranged side by side in the vertical direction between the inner layer sheets 21, 31 and the outer layer sheets 22, 32, and are fixed in a stretched state in the left-right direction. Therefore, the abdominal waistline portion 20 and the back waistline portion 30 expand and contract in the left-right direction to fit the wearer's waistline. Examples of the thread-like elastic members 23 and 33 include thread-like elastic members such as rubber and spandex.

In the back waistline portion 30, the thread-like elastic members 33 are arranged from the upper end portion to the lower end portion. On the other hand, at the upper end portion of the abdominal waistline portion 20, the thread-like elastic member 23 is not arranged, but instead, the elastic sheet 24 that expands and contracts in the left-right direction is arranged. In the present embodiment, the lower end portion of the elastic sheet 24 and the thread-like elastic member 23 are arranged so as to overlap each other in the vertical direction, but they do not have to overlap.

In this way, by disposing the elastic sheet 24 without arranging the thread-like elastic member 23 on the upper end of the abdominal waistline portion 20, the upper end of the abdominal waistline portion 20 comes into close contact with the wearer on the surface. Therefore, local tightening is suppressed, and it is possible to make it difficult for traces of the elastic member to remain. In particular, since the baby's abdomen is protruding, it is preferable to suppress the tightening of the abdominal girth 20.

The expandability of the upper ends of the waist portions 20, 30 greatly affects the ease with which the waist opening BH is widened when the diaper 1 is worn. The stretchable sheet 24 has a property that it is easily stretched from its natural state and is difficult to shrink from its stretched state. Therefore, by disposing the elastic sheet 24 on the upper end portion of the abdominal waistline portion 20, it becomes easy to widen the waistline opening portion BH when the diaper 1 is worn, and after the waistline portions 20 and 30 are fitted to the wearer. Tightening of the abdomen can be prevented.

The stretchable sheet 24 includes, for example, a spunbonded nonwoven fabric, an air-through nonwoven fabric, a needle punched nonwoven fabric, etc. composed of elastic fibers having a mass of 10 to 40 g/m ² , and more preferably a mass of 15 to 30 g/m ^2. A stretchable fibrous nonwoven fabric manufactured by a known manufacturing method can be used. The elastic fiber is made of a thermoplastic elastomer, rubber or the like as a raw material, and particularly when a thermoplastic elastomer is used as a raw material, it is possible to perform melt spinning using an extruder like an ordinary thermoplastic resin. Further, the fibers thus obtained are easily heat-bonded and are suitable as a stretchable fibrous nonwoven fabric. Examples of thermoplastic elastomers include styrene-based elastomers, olefin-based elastomers, polyester-based elastomers, and polyurethane-based elastomers. These can be used alone or in combination of two or more. The stretchable sheet may have elasticity in at least the left-right direction, and may have elasticity in two or more directions. The stretch ratio of the stretchable sheet 24 in the left-right direction is preferably about 1.2 times to 3.0 times.

===End of the elastic sheet 24 on the waist opening BH side===
FIG. 4 is a cross-sectional view of the abdominal waistline portion 20 during manufacturing. FIG. 5 is a cross-sectional view of the abdominal waistline portion 20 in a product state. FIG. 6 is a plan view of the ventral waistline portion 20 shown in FIG. 4. 4 and 5 are diagrams schematically showing the configuration of the abdominal waistline portion 20, and the thickness of the abdominal waistline portion 20 is drawn thick. The same applies to the sectional views described below. Further, in FIG. 6, the thread-shaped elastic member 23 is omitted.

As described above, the abdominal waistline portion 20 includes the inner layer sheet 21, the outer layer sheet 22, and the stretchable sheet 24. In the state of being manufactured (FIG. 4 ), the outer layer sheet 22, the inner layer sheet 21, and the stretchable sheet 24 are laminated in order from the non-skin side in the thickness direction.

As shown in FIG. 6, the inner layer sheet 21, the outer layer sheet 22, and the elastic sheet 24 each have one end 21a, 22a, 24a and the other end 21b, 22b, 24b extending in the left-right direction. In the product state (FIG. 5), one end 21a, 22a, 24a of each sheet is located above the other end 21b, 22b, 24b.

The inner layer sheet 21 and the outer layer sheet 22 are joined by an adhesive agent (not shown) applied between them. The inner layer sheet 21 and the outer layer sheet 22 correspond to the non-stretchable sheet of the present invention. Hereinafter, the inner layer sheet 21 and the outer layer sheet 22 are collectively referred to as a non-stretchable sheet.

In the state in the middle of manufacturing (FIG. 4 ), the position of one end 21 a of the inner layer sheet 21 and the position of one end 24 a of the elastic sheet 24 are aligned in the vertical direction. The outer layer sheet 22 extends above the inner layer sheet 21 and the stretchable sheet 24.

In the product state (FIG. 5), the outer layer sheet 22 is folded back downward with the positions of the ends 21a and 24a of the inner layer sheet 21 and the elastic sheet 24 being the folding positions F. The part 221 of the folded back outer layer sheet 22 covers the longitudinal end of the absorbent main body 10 from the skin side. Further, the folded back portion 221 of the outer layer sheet 22 is fixed to the stretchable sheet 24 and the absorbent main body 10 by the adhesive 42.

An adhesive 41 such as a hot melt adhesive is applied between the non-stretchable sheet (the inner layer sheet 21 and the outer layer sheet 22) and the stretchable sheet 24. The elastic sheet 24 is fixed to the non-stretchable sheets 21 and 22 by the adhesive 41. As shown in FIG. 6, the application area of the adhesive 41 is a rectangular area in plan view. The application area of the adhesive 41 corresponds to the fixing portion of the present invention. Hereinafter, the application area of the adhesive 41 is also referred to as the fixing portion 41.

The adhesive 41 may be partially applied to the application area of the adhesive 41, or the adhesive 41 may be applied to the entire area. As the application pattern of the adhesive agent 41, known patterns such as a stripe pattern, a spiral pattern, an Ω pattern and the like can be exemplified. The planar shape of the application area of the adhesive 41 is not limited to the rectangular shape. Further, the fixing portion is not limited to the adhesive 41, and may be a welding region in which the stretchable sheet 24 is fixed to the non-stretchable sheets 21 and 22 by heat welding, ultrasonic welding, or the like.

As shown in FIG. 6, the fixed portion 41 has one end 41a and the other end 41b extending in the left-right direction. In the product state (FIG. 5), one end 41a of the fixed portion 41 is located above the other end 41b. The fixing portion 41 is provided so as to straddle one end 24a of the elastic sheet 24 in the vertical direction.

Specifically, in the mid-manufacturing state (FIG. 4 ), the fixing portion 41 is provided between the stretchable sheet 24 and the inner layer sheet 21, and passes over the one end 24 a of the stretchable sheet 24 and the skin of the outer layer sheet 22. It is also provided on the side. Therefore, in the product state (FIG. 5 ), a part of the fixing portion 41 is also folded back as the outer layer sheet 22 is folded back, and the fixing portion 41 covers one end 24 a of the elastic sheet 24 from above. There is. Therefore, in the product state (FIG. 5), the fixing portion 41 is provided so as to straddle one end 24a of the stretchable sheet 24 in the vertical direction.

Since the fixing portion 41 is provided in this manner, the portion of the stretchable sheet 24 on the side of the one end 24a is fixed to the non-stretchable sheets 21 and 22 up to the one end 24a. Therefore, during manufacturing, it is possible to prevent the portion of the stretchable sheet 24 on the side of the one end 24a (that is, the end portion on the waistline opening BH side) from being unintentionally turned over by the shrinkage force of the stretchable sheet 24.

The stretchable sheet 24 being turned up means that the end portion of the stretchable sheet 24 rises in the thickness direction or the end portion of the stretchable sheet 24 is folded back up and down due to the folding start point extending in the left-right direction of the diaper 1. Is to end up. If the ends of the stretchable sheet 24 are folded back and the stretchable sheets 24 are stacked, the stretchable force in the left-right direction increases by the amount of the stretched sheet 24 that has been folded back.

Therefore, by suppressing the folding back of the portion of the elastic sheet 24 on the side of the one end 24a, it is possible to prevent the lateral stretching force of the abdominal waistline portion 20 from becoming larger than the designed force. .. Therefore, the easiness of opening the waistline opening BH when the diaper 1 is worn can be maintained, and tightening of the wearer's abdomen can be prevented.

The expandability of the upper ends of the waistline portions 20 and 30 greatly affects the ease with which the waistline opening BH can be expanded. Therefore, when the elastic sheet 24 is provided on the upper end of the abdominal waistline portion 20 as in the diaper 1 of the present embodiment, the folding back of the part of the elastic sheet 24 on the side of the one end 24a is suppressed. Will be effective. By doing so, the ease of expanding the waistline opening BH can be maintained.

The elastic sheet 24 is provided on the upper end portion of the abdominal waistline portion 20 means that at least a part of the elastic sheet 24 is closer to the center CL (see FIG. 5) of the abdominal waistline portion 20 in the vertical direction. Is also located above. More preferably, all of the stretchable sheet 24 is located above the center CL of the abdominal waistline portion 20.

Further, in the product state (FIG. 5 ), the portion on the side of the one end 22 a of the outer layer sheet 22 is folded back downward. The length in the vertical direction from the upper end 20a of the abdominal waistline portion 20 to one end (here, one end 22a of the outer layer sheet 22) of the non-stretchable sheet folded back is defined as the length L1. On the other hand, the vertical length from the upper end 20a of the abdominal waistline portion 20 to the one end 24a of the elastic sheet 24 is zero. This length (zero) may be shorter than the length L1.

That is, the one end 24a of the elastic sheet 24 may be located above the one end 22a of the folded back outer layer sheet 22. By doing so, the elastic sheet 24 will not be located too downward. Therefore, the fit of the upper end portion of the abdominal waistline portion 20 can be maintained.

Further, the fixing portion 41 fixes the one surface 24A (non-skin side surface in FIG. 4) of both surfaces of the stretchable sheet 24 to the non-stretchable sheets 21 and 22, and other than the first area 411. Second region 412 of The second region 412 of the fixed portion 41 is continuous with the first region 411, and extends beyond the one end 24a of the stretchable sheet 24 and is fixed to the non-stretchable sheet (here, the outer layer sheet 22). Area.

In the state of being manufactured (FIG. 4 ), the first region 411 of the fixing portion 41 is located between the stretchable sheet 24 and the inner layer sheet 21 and is not exposed. On the other hand, the second region 412 of the fixing portion 41 provided on the outer layer sheet 22 is exposed on the skin side. If the second region 412 of the fixing portion 41 is exposed to the skin side in the product state, the solidified adhesive agent 41 contacts the wearer, and the comfort of the abdominal waistline portion 20 deteriorates. Further, although not shown, even when the second region 412 of the fixed portion 41 is exposed to the non-skin side, the tactile comfort of the abdominal waistline portion 20 from the outside is deteriorated.

Therefore, it is preferable that at least a part of the second region 412 of the fixed portion 41 is not exposed. More preferably, not all of the second region 412 of the fixing portion 41 is exposed. That is, the second region 412 of the fixing portion 41 may be located between the materials that make up the diaper 1.

In the present embodiment, the second region 412 of the fixing portion 41 is covered from the skin side by the region 221 of the outer layer sheet 22 folded back. In other words, the second region 412 of the fixed portion 41 is located between the folded back portion 221 of the outer layer sheet 22 and the stretchable sheet 24 and is not exposed. Therefore, it is possible to suppress a decrease in the wearing comfort of the abdominal waistline portion 20 and a decrease in the touch feeling.

The configuration of the abdominal waistline portion 20 is not limited to that shown in FIG. For example, a configuration in which the inner layer sheet 21 is folded back together with the outer layer sheet 22, a configuration in which only the inner layer sheet 21 is folded back, and a configuration in which the inner layer sheet 21 and the outer layer sheet 22 are not folded back. And so on. Therefore, the material that covers the second region 412 of the fixing portion 41 from the skin side is not limited to the outer layer sheet 22. For example, the inner layer sheet 21 folded back downward, or another sheet other than the non-stretchable sheets 21 and 22 may be used.

Further, in the product state (FIG. 5 ), the portion of the stretchable sheet 24 on the side of the one end 24 a is not folded back downward. That is, the method for manufacturing the diaper 1 does not have a step of folding back the portion of the stretchable sheet 24 on the side of the one end 24a in the vertical direction. Further, the fixing portion 41 straddling the one end 24a of the elastic sheet 24 prevents the elastic sheet 24 from being turned up.

Therefore, the number of the stretchable sheets 24 to be laminated is one at the upper end of the abdominal waistline portion 20. That is, the stretching force in the left-right direction at the upper end portion of the abdominal waistline portion 20 is appropriately suppressed. Therefore, when the diaper 1 is worn, the waistline opening BH can be easily expanded, and tightening of the wearer's abdomen can be prevented.

On the other hand, in the product state (FIG. 5), the portion of the fixed portion 41 on the side of the one end 41a is folded back downward. That is, the manufacturing method of the diaper 1 has a step of folding the fixing portion 41 downward together with the outer layer sheet 22.

Therefore, the fixing portion 41 is laminated in the thickness direction at the upper end of the abdominal waistline portion 20. That is, the number of layers of the adhesive 41 is two, and the rigidity of the upper end portion of the abdominal waistline portion 20 is enhanced. Therefore, when wearing the diaper 1, it becomes easier to grip the upper end of the abdominal waistline portion 20, and it becomes easier to pull up the diaper 1. Further, it is possible to prevent the upper end portion of the abdominal waistline portion 20 from being turned up and to have a crease during packaging, and to prevent the appearance of the diaper 1 from being deteriorated.

=== Modified example ===
7 to 10 are sectional views of modified examples of the abdominal waistline portion 20. 9A and 10A are views of the abdominal waistline portion 20 during manufacturing. The other drawings are views of the abdominal waistline portion 20 in a product state.

In the abdominal waistline portion 20 of FIGS. 7A, 7B, and 8, as in FIG. 5, the portion of the stretchable sheet 24 on the side of the one end 24a is not folded downward. However, one end 24a of the elastic sheet 24 is located below the upper end 20a of the abdominal waistline portion 20. The fixing portion 41 that straddles one end 24a of the elastic sheet 24 in the vertical direction suppresses the part of the elastic sheet 24 on the side of the one end 24a from being turned up.

7A, 7B, and 8, in the abdominal waistline portion 20, the vertical length L2 from the upper end 20a of the abdominal waistline portion 20 to the one end 24a of the elastic sheet 24 is the abdominal waistline portion. It is shorter than the vertical length L1 from the upper end 20a of the sheet 20 to the one end 22a of the outer layer sheet 22 (L2<L1). That is, the elastic sheet 24 is not located too downward. Therefore, the fit of the upper end portion of the abdominal waistline portion 20 can be maintained.

Further, in the abdominal waistline portion 20 of FIG. 7B, similarly to FIG. 5, the portion on the side of the one end 41a of the fixing portion 41 is folded back downward. Therefore, the rigidity of the upper end portion of the abdominal waistline portion 20 is enhanced.

On the other hand, in the abdominal waistline portion 20 of FIGS. 7A and 8, the portion of the fixing portion 41 on the side of the one end 41a is not folded back downward. Therefore, in the upper end portion of the abdominal waistline portion 20, the fixing portion 41 has one layer, and the upper end portion of the abdominal waistline portion 20 is soft.

Further, in the abdominal waistline portion 20 of FIG. 8, one end 24a of the elastic sheet 24 and one end 41a of the fixing portion 41 are located below the upper end 20a of the abdominal waistline portion 20. Therefore, in the upper end portion of the abdominal waistline portion 20, there is a region where the elastic sheet 24 and the fixing portion 41 are not located. Therefore, the upper end of the abdominal waistline portion 20 is even softer.

When the upper end portion of the abdominal waistline portion 20 is soft, it is possible to prevent the upper end (edge) 20a of the abdominal waistline portion 20 from stimulating the skin of the wearer. Further, in the natural state of the diaper 1, the upper end portion of the abdominal waistline portion 20 is likely to be frilled. Therefore, the user can get the impression that the diaper 1 is soft and comfortable to wear.

In the abdominal waistline portion 20 of FIG. 9B, the portion on the side of the one end 24a of the elastic sheet 24 is folded back downward. Therefore, in the state of being manufactured (FIG. 9A), the stretchable sheet 24 extends above the inner layer sheet 21 similarly to the outer layer sheet 22. Then, the method for manufacturing the diaper 1 includes a step of folding the elastic sheet 24 together with the outer layer sheet 22 downward. Therefore, the number of the stretchable sheets 24 stacked on the upper end of the abdominal waistline portion 20 is two. Therefore, in the abdominal waistline portion 20 of FIG. 9B, the stretching force in the left-right direction is increased as compared with the abdominal waistline portion 20 of FIG. 5 and the like.

Also in the abdominal waistline portion 20 of FIG. 9B, the fixing portion 41 straddling the one end 24a of the elastic sheet 24 suppresses the portion of the elastic sheet 24 on the one end 24a side from being turned up. Therefore, the number of laminated stretchable sheets 24 is three or more, and the stretchable force of the abdominal waistline portion 20 can be prevented from becoming larger than the designed force.

Further, in the abdominal waistline portion 20 of FIG. 9B, an adhesive for fixing the stretchable sheets 24 to each other is not provided, and a portion of the folded back stretchable sheet 24 on the side of the one end 24a and an unfolded stretchable portion. The surface facing the part of the property sheet 24 is not fixed. Therefore, the space 24B is formed between the folded back portion and the non-folded back portion of the elastic sheet 24, and the cushioning property of the upper end portion of the abdominal waistline portion 20 is high. Therefore, it is possible to improve the skin contact with the wearer.

In addition, in the abdominal waistline portion 20, the portion where the elastic sheet 24 is provided has a smoother surface than the portion where the thread-like elastic member 23 is provided, and the finger is less likely to be caught when the diaper 1 is pulled up. However, in FIG. 9B, the elastic sheet 24 has two layers, and the space 24</b>B formed between the elastic sheets 24 increases the thickness of the upper end portion of the abdominal waistline portion 20. The thickened portion becomes a handle, and the diaper 1 can be easily pulled up.

Also in the abdominal waistline portion 20 of FIG. 9B, the vertical length L2 from the upper end 20a of the abdominal waistline portion 20 to the one end 24a of the elastic sheet 24 is from the upper end 20a of the abdominal waistline portion 20 to the outer layer sheet. It is preferable that the length L1 up to one end 22a of 22 is shorter than the vertical length L1 (L2<L1). By doing so, the length of the folded elastic sheet 24 does not become too long, and the region where the elastic sheet 24 has two layers can be reduced. That is, the stretching force in the left-right direction of the abdominal waistline portion 20 can be appropriately suppressed.

Further, the elastic sheet 24 may be fixed by the fixing portion 41 to the portion 221 of the outer layer sheet 22 folded back like the ventral waistline portion 20 of FIG. 10B. It is preferable that the stretchable sheet 24 and the inner layer sheet 21 that are folded back are fixed by an adhesive 43.

In this case, in the state of being manufactured (FIG. 10A), the lower end 24a of the elastic sheet 24 becomes the one end 24a of the elastic sheet 24, and the fixing portion 41 extends downward beyond the lower end 24a of the elastic sheet 24. There is. By doing so, in the product state (FIG. 10B ), it is possible to prevent the stretchable sheet 24 from being turned over at the portion on the side of the one end 24 a (that is, the end portion on the waist opening BH side).

===Regarding the crotch end of the elastic sheet 24===
11 to 15 are explanatory views of the crotch-side end portion of the elastic sheet 24, and are cross-sectional views of the abdominal waistline portion 20 in a product state.

The fixing portion 41 for fixing the stretchable sheet 24 to the non-stretchable sheets 21 and 22 may be provided, for example, as shown in FIG. 10B described above, by straddling the other end 24b of the stretchable sheet 24 in the vertical direction. Good. In this case, it is possible to prevent the portion of the stretchable sheet 24 on the side of the other end 24b (that is, the crotch end portion) from being turned up.

Further, as shown in FIGS. 5 and 6 described above, the fixing portion 41 may not be provided so as to straddle the other end 24b of the elastic sheet 24 in the vertical direction. That is, the fixing portion 41 does not have to be provided at the portion of the elastic sheet 24 on the side of the other end 24b. In this case, as shown in FIGS. 11 to 15, the portion of the elastic sheet 24 on the side of the other end 24b is turned up by the contracting force of the elastic sheet 24.

This is because in the manufacturing process of the diaper 1, a small difference occurs in how tension is applied to the stretchable sheet 24 during transportation after the stretchable sheet 24 is fixed to the non-stretchable sheets 21 and 22, and thus the stretchable sheet 24 is stretched. It is thought that 24 is locally contracted to turn over. In addition, it is considered that the elastic sheet 24 is also turned up when the elastic sheet 24 is expanded and returned in the width direction intersecting the extending direction of the elastic sheet 24.

The part of the elastic sheet 24 on the side of the other end 24b overlaps with the absorbent main body 10 or is located near the absorbent main body 10. Therefore, the portion of the elastic sheet 24 on the side of the other end 24b is not only flipped up and rises in the thickness direction, but is also easily folded back upward from the lower end 41b (the other end) of the fixing portion 41.

In addition, when the elastic sheet 24 is folded back, it may be folded so that a folding line extending in the left-right direction is formed, or folded back so that the lower end of the elastic sheet 24 is curved as shown in FIG. 11A and the like. It may be curled, that is, it may be curled. In addition, in the drawings before FIG. 9, in order to prevent complication of the drawing, a part of the elastic sheet 24 on the side of the other end 24b is not folded back.

The part of the stretchable sheet 24 on the side of the other end 24b is folded back to form two layers, so that the stretchable force of the crotch-side end of the stretchable sheet 24 in the left-right direction can be increased. That is, the stretching force of the part of the abdominal girth 20 that overlaps the absorbent main body 10 or a part in the vicinity thereof can be increased. Therefore, the displacement of the absorbent main body 10 (the absorbent core 11A) can be suppressed. For example, it is possible to suppress the sagging of the absorbent main body 10 that has absorbed the excreted liquid. Therefore, the fit of the absorbent main body to the wearer can be maintained even after excretion, and leakage of excrement can be reduced. In addition, the wearer does not feel uncomfortable, and walking is easy.

In addition, the elastic force of the crotch-side end of the elastic sheet 24 is less likely to affect the ease of spreading the waistline opening BH than the elastic force of the end on the waistline opening BH side. Therefore, even if the crotch-side end of the stretchable sheet 24 has two layers, the easiness of expanding the waistline opening BH can be maintained.

Further, the folding back of the crotch-side end of the elastic sheet 24 utilizes the contracting force of the elastic sheet 24. That is, the manufacturing method of the diaper 1 does not have a step of folding back the portion of the stretchable sheet 24 on the side of the other end 24b. Therefore, it can be said that the elastic force of the crotch-side end portion of the elastic sheet 24 can be increased without complicating the manufacturing method of the diaper 1.

In addition, the pants-type diaper 1 has a pair of joint regions 2 in which both side ends of the abdominal waistline portion 20 and both side ends of the back side waistline portion 30 in the left-right direction are welded to each other. As shown in FIG. 6, the stretchable sheet 24 is preferably provided so as to extend to the outside of the formation position of the joining region 2 in the left-right direction. Then, it is preferable that the joining region 2 is formed in a state in which the portion on the other end 24b side of the elastic sheet 24 is folded back upward. By doing so, the folding back of the portion of the elastic sheet 2 on the side of the other end 24b is maintained.

Next, with reference to FIGS. 11 to 15, a vertical position of a portion where the elastic sheet 24 is folded back (hereinafter, also referred to as a folded portion 241) will be described. The folding|returning part 241 is specifically the part from the part 24c of the elastic sheet 24 which contacts the other end 41b of the fixed part 41 to the other end 24b of the elastic sheet 24.

In the abdominal waistline portion 20 shown in FIGS. 11A, 12A, 13A, 14A, and 15A, the folded portion 241 of the elastic sheet 24 is located on the non-skin side of the absorbent main body 10. On the other hand, in the abdominal waistline portion 20 shown in FIGS. 11B, 12B, 13B, 14B, and 15B, the folded portion 241 of the elastic sheet 24 is located on the skin side of the absorbent main body 10.

Then, in the abdominal waistline portion 20 of FIGS. 11A and 11B, the folded-back portion 241 of the stretchable sheet 24 is located above the upper end 10 a of the absorbent main body 10. That is, the folded-back portion 241 does not overlap with the absorbent main body 10 in the vertical direction.

In this case, the folding|returning part 241 can make the site|part of the abdominal girth part 20 near the absorptive main body 10 contact|adhere to a wearer. Therefore, the displacement of the absorbent main body 10 (the absorbent core 11A) can be suppressed. Further, the elastic force of the folded-back portion 241 is less likely to be hindered by the highly rigid absorbent main body 10.

12A and 12B, in the ventral waistline portion 20, the folded portion 241 of the elastic sheet 24 is located below the upper end 10a of the absorbent main body 10 and above the upper end 11Aa of the absorbent core 11A. is doing. That is, in the up-down direction, the folded-back portion 241 overlaps with the upper end portion (top sheet 12, back sheet 13, exterior sheet 14, core wrap sheet 11B) of the absorbent main body 10 but overlaps with the absorbent core 11A. I haven't.

And the folding|returning part 241 of FIG. 12A is located in the non-skin side rather than the absorptive main body 10. Therefore, the folding|returning part 241 can make an upper end part of the absorptive main body 10 contact|adhere to a wearer from the non-skin side, and can suppress the position gap of the absorptive main body 10 (absorptive core 11A).

On the other hand, the folding|returning part 241 of FIG. 12B is located in the skin side rather than the absorptive main body 10. Also in this case, the folding|returning part 241 can make the site|part of the abdominal girth part 20 which overlaps the upper end part of the absorptive main body 10 contact|adhere to a wearer, and the position gap of the absorptive main body 10 (absorptive core 11A). Can be suppressed. Further, in FIG. 12B, the elastic sheet 24 covers the upper end 10 a of the absorbent main body 10 from the skin side together with the outer layer sheet 22. Therefore, it is difficult for the wearer to feel the contact with the upper end 10a (edge) of the absorbent main body 10, and it is difficult for the wearer to feel the foreign body.

In addition, the region of the absorbent main body 10 in which the absorbent core 11A exists has higher rigidity than the region in which the absorbent core 11A does not exist. Therefore, in the case of FIGS. 12A and 12B, the elastic force of the folded-back portion 241 is less likely to be hindered by the highly rigid absorbent core 11A.

In the abdominal waistline portion 20 of FIGS. 13A and 13B, the folded-back portion 241 of the elastic sheet 24 is provided so as to straddle the upper end 10a of the absorbent main body 10 in the vertical direction. In this case, the number of materials can be gradually changed around the upper end 10a of the absorbent main body 10.

Specifically, from the upper side to the lower side, an area in which the elastic sheet 24 is one layer, an area in which the elastic sheet 24 is two layers (folding portion 241), and two layers of the elastic sheet 24 (folding portion). It is possible to sequentially increase the number of materials in the region where the absorbent main body 10 is laminated in 241). Therefore, a step difference and a difference in rigidity between the region where the absorbent main body 10 is present and the region where the absorbent main body 10 is not present are reduced, and it is difficult for the wearer to feel a foreign body.

In particular, in FIG. 13B, the folded portion 241 of the elastic sheet 24 covers the upper end 10a of the absorbent main body 10 from the skin side. Therefore, the wearer is less likely to feel the upper end 10a (edge) of the absorbent main body 10 than in the case of FIG. 12B, and is less likely to give the wearer a feeling of foreign matter.

14A and 14B, the folded-back portion 241 of the elastic sheet 24 is located below the upper end 11Aa of the absorbent core 11A. That is, the folded-back portion 241 overlaps the absorbent core 11A in the vertical direction.

And the folding|returning part 241 of FIG. 14A is located in the non-skin side rather than the absorptive core 11A. Therefore, the folding|returning part 241 can adhere|attach the absorbent core 11A to a wearer from the non-skin side, and can suppress the position gap of the absorptive main body 10 (absorbent core 11A). Further, since the absorbent core 11A absorbs the excreted liquid and becomes heavy, the portion of the absorbent main body 10 where the absorbent core 11A is present is most likely to be displaced. Therefore, in FIG. 14A, the site|part of the absorptive main body 10 which is easy to be displaced can be brought into close contact with the wearer.

On the other hand, the folding|returning part 241 of FIG. 14B is located in the skin side rather than the absorptive core 11A. Also in this case, the folding|returning part 241 can make a wearer adhere|attach the part of the abdominal waist part 20 which overlaps with the part of the absorptive main body 10 which is most apt to be displaced, and the absorptive main body 10 (absorbent core). 11A) can be suppressed from being displaced. Moreover, in FIG. 14B, the elastic sheet 24 covers the upper ends 10a and 11Aa of the absorbent main body 10 and the absorbent core 11 from the skin side. Therefore, the wearer is less likely to feel the upper ends (edges) 10a and 11Aa of the absorbent main body 10 and the absorbent core 11, and is less likely to give the wearer a feeling of foreign matter.

In the abdominal waistline portion 20 of FIGS. 15A and 15B, the folded-back portion 241 of the elastic sheet 24 is provided so as to straddle the upper end 11Aa of the absorbent core 11A in the vertical direction. In this case, the number of materials can be gradually changed around the upper end 11Aa of the absorbent core 11A.

Specifically, from the upper side to the lower side, a region where the upper end of the absorbent main body 10 and the one-layer elastic sheet 24 are stacked, the upper end of the absorbent main body 10 and the two-layer elastic sheet 24 (folded back). The number of materials can be increased in order from the region where the portion 241) is laminated, the region where the absorbent core 11A is present in the absorbent main body 10 and the region where the two-layer stretchable sheet 24 is laminated. Therefore, the step difference and the difference in rigidity between the region where the absorbent core 11A exists and the region where the absorbent core 11A does not exist are reduced, and it is difficult for the wearer to feel a foreign body.

In particular, in FIG. 15B, the folded portion 241 of the stretchable sheet 24 covers the upper end 11Aa of the absorbent core 11 from the skin side. Therefore, the wearer is less likely to feel the upper end (edge) 11Aa of the absorbent core 11A than in the case of FIG. 14B, and is less likely to give the wearer a feeling of foreign matter.
