<Embodiment 1>
EMBODIMENT OF THE INVENTION Below, the diaper based on Embodiment 1 of this invention is demonstrated with reference to drawings. Note that the configurations of the following embodiments are illustrative, and the present invention is not limited to the configurations of these embodiments.

FIG. 1 is an example of a perspective view of a pants-type disposable diaper for adults (hereinafter simply referred to as "diaper") according to Embodiment 1. In a diaper, the longitudinal direction (also referred to as the front-rear direction) is the direction that connects the front body, which is arranged to face the wearer's abdomen, and the back body, which is arranged to face the wearer's back. Between the front body (on one side in the longitudinal direction) and the back body (on the other side in the longitudinal direction) (at the center in the longitudinal direction) is an inseam that is placed at the wearer's crotch (located opposite the crotch). Department is located. Further, when the diaper is worn by a wearer, the side facing the wearer's skin is defined as the skin side, and the side opposite to the skin side is defined as the non-skin side. Further, the direction connecting the skin side and the non-skin side is defined as the thickness direction, and the direction perpendicular to both the longitudinal direction and the thickness direction is defined as the width direction (also referred to as the left-right direction). In addition, viewing from the thickness direction is considered to be a planar view. The diaper 1 has a length along the longitudinal direction and a length along the width direction perpendicular to the longitudinal direction, and is worn on the wearer's crotch. Moreover, the terminology used in this application regarding direction shall mean the direction corresponding to the front, back, left, and right of the wearer when the diaper 1 is worn by the wearer. For example, in the present application, the left-right direction refers to the direction that corresponds to the left and right sides of the wearer when the diaper 1 is worn by the wearer.

In this embodiment, as an example of an absorbent article, a cylindrical structure having a waist opening through which the wearer's abdominal circumference can be inserted and a pair of left and right leg openings through which the wearer's left and right lower legs can be inserted. A pants-type disposable diaper is illustrated. Furthermore, in this embodiment, a pants-type disposable diaper for adults is exemplified, but the "absorbent article" in the present application is not limited to pants-type disposable diapers for adults. The term "absorbent article" as used herein includes pants-type disposable diapers for children.

The diaper 1 has an inseam region 1B that corresponds to the crotch region that covers the genitals (inseam) of the wearer when worn, and a region that corresponds to the front body of the wearer's waist and covers the abdomen side of the wearer. It has a front body region 1F for covering the wearer's back, and a back body region 1R for covering the back side of the wearer, which corresponds to the back body in the wearer's torso. Here, the front body region 1F is located on the front side of the crotch region 1B, and the back body region 1R is located on the rear side of the crotch region 1B. Since the diaper 1 in this embodiment is a pants-type disposable diaper, the side seal portion 3SL that joins the left edge of the front body region 1F and the left edge of the back body region 1R to each other, and the side seal portion 3SL of the front body region 1F. A side seal portion 3SR is provided that joins the right edge and the right edge of the back body region 1R to each other. By the side seal parts 3SL and 3SR, a torso opening 2T (an example of the "waist opening" of the present disclosure) is formed in the diaper 1 by the upper edge of the front body region 1F and the upper edge of the back body region 1R. has been done. Further, in the diaper 1, a left lower leg opening 2L is formed on the left side of the crotch area 1B, which is not joined, and a right lower leg opening 2R is formed on the right side of the crotch area 1B. It can be said that left and right lower limb openings 2L and 2R are formed in the diaper 1 by the side seal parts 3SL and 3SR. The diaper 1 is configured such that the wearer's left lower leg is inserted through the left lower leg opening 2L, the wearer's right lower leg is inserted through the right lower leg opening 2R, and the wearer's torso is inserted into the torso opening 2T. When worn, the front body area 1F is placed on the wearer's abdomen side, the back body area 1R is placed on the wearer's back side, and the left lower leg opening 2L and right lower leg opening 2R are placed on the wearer's thigh. It is fixed to the wearer's body in a state surrounding the body. Since the diaper 1 is fixed to the wearer's body in this manner, the wearer can move freely while wearing the diaper 1. Note that the left lower limb opening 2L and the right lower limb opening 2R are examples of "left and right leg openings" of the present disclosure.

In the diaper 1, absorbent bodies capable of absorbing and retaining liquid are arranged mainly around the crotch region 1B. The diaper 1 also includes a left lower leg opening that surrounds the thigh of the wearer's left lower leg in order to prevent a gap from forming between the diaper 1 and the wearer's skin as a liquid outflow path. Three-dimensional gathers 3BL are provided in 2L, three-dimensional gathers 3BR (not shown in FIG. 1) are provided in the right lower leg opening 2R surrounding the thigh of the wearer's right lower leg, and waist gathers are provided in the region surrounding the wearer's abdominal circumference. 3R and tummy gathers 12 are provided. Further, leg gathers 3LF and 3LR (leg gathers 3LR are not shown in FIG. 1) are provided at positions surrounding the base of the wearer's legs. Note that the leg gathers 3LF are provided in the front body region 1F, and the leg gathers 3LR are provided in the back body region 1R. In FIG. 1, only the leg gathers 3LF are illustrated. The three-dimensional gathers 3BL, 3BR and the waist gathers 3R are contracted by the elastic force of the elastic member and are brought into close contact with the wearer's skin. Further, the leg gathers 3LF and 3LR prevent a gap from being created between the wearer's groin and the diaper 1. Therefore, the liquid discharged from the wearer's genitals is absorbed into the absorbent body of the diaper 1 without leaking from the diaper 1.

Note that the diaper 1 can be used in combination with an inner pad (not shown). The inner pad is a generally rectangular absorbent article that includes an absorbent body and absorbs the wearer's exudate. When the diaper 1 and the inner pad are used in combination, the inner pad is placed on the skin side of the diaper 1 so as to come into contact with the wearer's discharge hole. The drained liquid is first absorbed by the inner pad, and only the drained liquid that cannot be absorbed by the inner pad reaches the absorbent body of the diaper 1 and is further absorbed. Therefore, even if the amount of discharged liquid is large, leakage of the discharged liquid from the diaper 1 can be prevented. Further, if the amount of drained liquid is small and the inner pad can absorb all of it, even if the drained liquid is drained, only the inner pad needs to be replaced, which can reduce the cost of assistance. Moreover, the diaper 1 can be used for a long time by reducing the frequency of changing the diaper 1.

FIG. 2 is an example of an exploded perspective view of the diaper 1 according to the first embodiment. The diaper 1 has a cover sheet 4 and an inner cover sheet 5. The cover sheet 4 and the inner cover sheet 5 are approximately hourglass-shaped (gourd-shaped) sheets that are bonded together to form the outer surface of the diaper 1, and have an end on the front body region 1F side and an end on the back body region 1R side. Other than that, they are the same shape and almost the same size. When worn by a wearer, the cover sheet 4 is laminated on the wearer's non-skin side, and the inner cover sheet 5 is laminated on the wearer's skin side. An elastic member for forming waist gathers 3R, tummy gathers 12, and leg gathers 3LF and 3LR is provided between the cover sheet 4 and the inner cover sheet 5. In this embodiment, a rubber thread is used as the elastic member. Note that as the elastic member, an elastic member such as a band-shaped rubber can be appropriately selected in place of the rubber thread.

The cover sheet 4 and the inner cover sheet 5 may be made of, for example, a nonwoven fabric made of a liquid-impermeable thermoplastic resin in order to suppress leakage of waste materials. Here, examples of the liquid-impermeable thermoplastic resin include polyethylene (PE) and polypropylene (PP). Hereinafter, the absorbent body 8 and the combination of the absorbent body 8 with the back sheet 6, top sheet 9, and side sheets 10L and 10R will be referred to as an interior body, and as a concept corresponding to the interior body, the cover sheet 4 on which rubber thread is arranged and Together with the inner cover sheet 5, it may be expressed as an exterior body (an example of the "exterior body" of the present disclosure).

The diaper 1 includes a backsheet 6, an absorbent body 8, and a topsheet 9, which are laminated in this order on the wearer side surfaces of a cover sheet 4 and an inner cover sheet 5. The back sheet 6 is a substantially rectangular sheet that has a length in the longitudinal direction that reaches from the front body of the wearer via the crotch to the back body, and has a predetermined width in the width direction perpendicular to the longitudinal direction. . The absorbent body 8 and the top sheet 9 are both sheet-like members having a substantially rectangular appearance like the back sheet 6, and are placed against the back sheet 6 with their longitudinal directions matching the longitudinal direction of the back sheet 6. They are stacked in order. The back sheet 6 is a sheet made of liquid-impermeable thermoplastic resin in order to suppress leakage of discharged materials. Further, the back sheet 6 is provided with minute holes. This hole allows ventilation while preventing liquid permeation. The holes are provided, for example, in a region that overlaps with the absorber 8. Further, the top sheet 9 is a sheet-like member that is placed on the wearer's skin side so as to cover the water-absorbing surface of the absorbent body 8. This top sheet 9 has liquid permeability in part or in whole. Therefore, when the diaper 1 is worn, liquid discharged from the wearer passes through the top sheet 9 that can come into contact with the wearer's skin and passes through the absorbent body 8.
penetrates and is absorbed there. Examples of liquid permeable sheets include woven fabrics, nonwoven fabrics, and porous films. Moreover, the top sheet 9 may have hydrophilicity.

The absorbent core 8 has an absorbent core 8c and a core wrap sheet 7 that wraps around the absorbent core 8c. The absorbent core 8c has a substantially hourglass shape with a constricted portion. The absorbent core 8c absorbs water into the gaps between short fibers of cellulose fibers such as pulp fibers, rayon fibers, or cotton fibers, or short fibers made of synthetic fibers such as polyethylene, polypropylene, or polyethylene terephthalate that have been subjected to a hydrophilic treatment. It has a structure that holds particulate absorbent resin (polymer absorbent material) such as SAP (Super Absorbent Polymer), which is a hydrophilic polymer with a crosslinked structure that can absorb and retain water. When the absorbent core 8c absorbs the liquid discharged from the wearer, it swells the absorbent resin held in the gaps within the short fibers and retains the liquid within the short fibers. The absorbent core 8c can have an appropriate shape depending on the purpose. Examples of the shape of the absorbent core 8c include a rectangular shape, an elliptical shape, and various other shapes. In this embodiment, the absorbent core 8c is formed of one mat, but the absorbent core 8c may be formed of a plurality of mats.

The core wrap sheet 7 is a thin liquid-permeable sheet, and by wrapping the absorbent core 8c with the core wrap sheet 7, the SAP of the above-mentioned absorbent core 8c becomes difficult to mix into other structures. Moreover, deformation of the absorbent core 8c is suppressed. The core wrap sheet 7 can be made of pulp fiber, and tissue paper can be used as an example. The core wrap sheet 7 may be a single sheet, but includes an upper sheet placed on the skin side of the wearer, and a lower sheet placed on the non-skin side of the wearer and wrapped around the sides and skin side of the absorbent core 8c. It may be composed of two side sheets. When the core wrap sheet 7 is composed of two sheets, a structure in which the widthwise end of the upper sheet is wrapped by other sheets (for example, side sheets 10L, 10R, back sheet 6, and top sheet 9, which will be described later) It may be . Note that the absorbent body 8 is wrapped in the back sheet 6 and the top sheet 9, and since these sheets can also prevent the absorbent body from losing its shape, the core wrap sheet 7 may not be provided.

The backsheet 6, absorbent core 8, and topsheet 9 all extend from the front body region 1F to the back body region 1R. Therefore, when the backsheet 6, absorbent body 8, and topsheet 9 are laminated to cover the wearer's genitals (crotch), both longitudinal ends of the backsheet 6, absorbent body 8, and topsheet 9 are covered by the wearer's genitals. It is located on the ventral and dorsal sides of the body. That is, the wearer's genitals are covered with the absorbent body 8 from the ventral side to the back side of the wearer. Therefore, even if the wearer discharges the liquid from the body in either a posture with the belly facing down or a posture with the back facing downward, the discharged liquid will come into contact with the absorbent body 8 via the top sheet 9. I will do it.

Moreover, the diaper 1 has long and narrow band-shaped side sheets 10L and 10R for forming the three-dimensional gathers 3BL and 3BR described above. The side sheets 10L and 10R are provided on the long sides of the top sheet 9. Rubber threads 10L1 and 10R1 are bonded to the side sheets 10L and 10R in a stretched state along the longitudinal direction. Therefore, the edge 4F4 of the cover sheet 4, which is the left edge of the front body region 1F, and the edge 4R4, which is the left edge of the back body region 1R, are joined to each other to form the side seal portion 3SL (see FIG. 1). The edge 4F5 of the cover sheet 4, which is the right edge of the front body region 1F, and the edge 4R5, which is the right edge of the back body region 1R, are joined to each other to form a side seal portion 3SR (see FIG. 1). As a result, when the diaper 1 is in the completed state as shown in FIG. 1, the side sheets 10L and 10R are pulled in the longitudinal direction by the contraction force of the rubber threads 10L1 and 10R1, and are pulled along the folding lines 10L2 and 10R2. Stand up from the top sheet 9 along the line. As a result, three-dimensional gathers 3BL and 3BR are formed that prevent liquid from flowing out from the left lower limb opening 2L and the right lower limb opening 2R.

Here, in the side sheets 10L and 10R, when the three-dimensional gathers 3BL and 3BR are formed, the interval in the width direction between the respective standing lines of the three-dimensional gathers 3BL and 3BR is provided to such an extent that an inner pad can fit therein. Note that the method of joining the edges 4F4 and 4R4, and the edges 4F5 and 4R5 is not particularly limited, but can be performed by, for example, heat sealing, high frequency sealing, ultrasonic sealing, or the like.

Furthermore, the diaper 1 includes an end sheet 11F that is laminated on the wearer side surface in the front body region 1F of the cover sheet 4, sandwiching the back sheet 6, the absorbent body 8, the top sheet 9, and the side sheets 10L and 10R. It has an end sheet 11R that is laminated on the wearer side surface in the rear body region 1R of the cover sheet 4. The end sheets 11F and 11R are strip-shaped sheets that are stacked on the cover sheet 4 and the inner cover sheet 5 at one end side in the longitudinal direction of the top sheet 9. The end sheets 11F and 11R are non-water permeable non-woven fabrics, and mainly reinforce the cover sheet 4 and the inner cover sheet 5 at the region of contact around the waist of the diaper 1. Moreover, an adhesive is applied to each of the end sheets 11F and 11R, and the end sheets 11F and 11R are bonded to the inner cover sheet 5 by the adhesive. The end sheets 11F and 11R are placed closer to the skin side than the laminate formed by the back sheet 6, absorbent body 8, top sheet 9, and side sheets 10L and 10R, and are worn with the ends of the laminate in direct contact with the skin surface. prevent people from feeling uncomfortable.

FIG. 3 is an example of a diagram schematically showing a state in which the diaper 1 according to the first embodiment is unfolded and stretched. FIG. 3(A) schematically shows the internal structure of the diaper 1 in an expanded and stretched state when viewed from the left side. FIG. 3(B) is a plan view of the diaper 1 in an expanded and stretched state.

As shown in FIG. 3, the thread rubber 4F3 (an example of the "second elastic member" of the present disclosure) forming the leg gathers 3LF is connected to the right lower leg opening 2R into which the wearer's legs enter when the diaper 1 is assembled. and along the edge of the left lower leg opening 2L on the front body region 1F side. The rubber thread 4F3 is bonded to the cover sheet 4 and the inner cover sheet 5 in a stretched state. The rubber thread 4F3 is provided so as to cross in the left-right direction in the crotch region 1B on the front body side. In the places where the rubber thread 4F3 is provided so as to cross in the left-right direction, the rubber thread 4F3 and the absorbent body 8 overlap in the thickness direction of the diaper 1. Further, the widthwise central portion of such a transverse region corresponds to the urethral opening of the wearer when the diaper 1 is worn. In addition, in the area|region where the absorber 8 overlaps in the thickness direction, the arrangement|positioning form of the thread rubber 4F3 is not limited to crossing as shown in FIG. 3. It is sufficient that the extending direction of the rubber thread 4F3 has a widthwise component, and preferably the widthwise component of the extending direction of the thread rubber 4F3 is larger than the longitudinal component.

On the other hand, the rubber thread 4R3 (an example of the "third elastic member" of the present disclosure) forming the leg gathers 3LR is provided along the edge of the right lower leg opening 2R and the left lower leg opening 2L on the rear body region 1R side. . The rubber thread 4R3 extends outward in the width direction of the diaper 1 from the absorbent body 8 along the left and right lower limb openings 2R and 2L on the back side of the wearer. The rubber thread 4R3 is bonded to the cover sheet 4 and the inner cover sheet 5 in a stretched state. In the crotch area 1B on the rear body side, the tip of the rubber thread 4R3 faces in the width direction. Further, the rubber thread 4R3 is cut at the center in the width direction, and the rubber thread 4R3 on the left side and the rubber thread 4R3 on the right side are not connected.

Further, the inner cover sheet 5 and the absorbent body 8 are appropriately bonded with adhesive via the back sheet 6 from the front body region 1F to the back body region 1R. However, as shown in FIG. 3, the inner cover sheet 5 and the absorbent core 8 are not bonded to each other in a region crossed by the rubber thread 4F3 in the front body region 1F (referred to as a non-bonded region 15). Actually, in the non-adhesive region 15, the inner cover sheet 5 and the back sheet 6 are non-adhered. In this embodiment, the non-adhesive area 15 is provided throughout the overlapping area of the crotch area 1B where the thread rubber 4F3 and the absorbent core 8 overlap.

One end of the cover sheet 4 is folded back along folding lines 4FF and 4RF shown in FIG. The above-mentioned waist gathers 3R are bonded to the front body region 1F of the cover sheet 4 with the thread rubber 4F1 stretched, and are bonded to the back body region 1R of the cover sheet 4 with the thread rubber 4R1 stretched. is formed. The rubber threads 4F1 and 4F2 are provided in the order of the rubber thread 4F1 and the rubber thread 4F2 from the folding line 4FF side along the folding line 4FF which will form the upper edge of the front body region 1F when folded back. Similarly, the tummy gathers 12 are bonded to the front body region 1F of the cover sheet 4 with the rubber thread 4F2 stretched, and to the back body region 1R of the cover sheet 4 with the rubber thread 4R2 stretched. It is formed by Similarly to the rubber threads 4F1 and 4F2, the rubber threads 4R1 and 4R2 are also folded from the folding line 4RF side along the folding line 4RF that forms the upper edge of the back body region 1R when folded back. They are arranged in this order.

Therefore, the rubber threads 4F1 and 4F2 are provided on the cover sheet 4 such that the longitudinal direction, which is the direction of expansion and contraction, is in the left-right direction of the diaper 1. Further, the rubber threads 4R1 and 4R2 are provided on the cover sheet 4 such that the longitudinal direction, which is the direction of expansion and contraction, is oriented in the left-right direction of the diaper 1. Therefore, when the edge 4F4 and the edge 4R4 are joined to each other and the edge 4F5 and the edge 4R5 are joined to each other, the thread rubber 4F1, 4F2 and the thread rubber 4R1, 4R2 form a substantially annular shape that goes around the trunk opening 2T. It forms a telescopic member and exhibits the function of contracting the trunk opening 2T in the direction of the waist circumference. That is, the rubber threads 4F1, 4F2 and the rubber threads 4R1, 4R2 exhibit contractile force to bring the diaper 1 into close contact with the wearer, thereby preventing a gap from being formed between the diaper 1 and the wearer's abdominal circumference. The rubber thread 4F2 and the rubber thread 4R2 overlap with the absorbent core 8 in a part of the crotch region 1B side. Note that the rubber threads 4F1 and 4F2 and the rubber threads 4R1 and 4R2 are examples of the first elastic member in the present disclosure.

The rubber threads 4F1 and 4R1 are provided so as to extend in the left-right direction along the upper edges of the front body region 1F and the back body region 1R shown in FIG. The rubber threads 4F2 and 4R2 are provided in parallel with a predetermined interval. The rubber threads 4F1 and 4R1 relatively strongly tighten the abdominal circumference of the wearer above the rubber threads 4F2 and 4R2 when the diaper 1 is worn. The rubber threads 4F1 and 4R1 have the function of keeping the diaper 1 in close contact with the wearer to prevent the wearer from shifting the wearing position, and to prevent fluid from leaking from the abdomen or back. The rubber threads 4F2 and 4R2 relieve the feeling of pressure on the wearer caused by the contraction force of the rubber threads 4F1 and 4R1.

The cover sheet 4 is folded back along folding lines 4FF and 4RF and extends to the region where the rubber thread 4F1 and the rubber thread 4R1 are arranged, and the folded portion reinforces the region where the rubber thread 4F1 and the rubber thread 4R1 are arranged. . The end sheets 11F and 11R (see FIG. 2) are provided in the arrangement area of the rubber thread 4F2 and the rubber thread 4R2 where the cover sheet 4 folded back at the folding lines 4FF and 4RF does not extend. The placement area is reinforced.

Note that in the present application, the state in which the sheets overlap is not limited to a state in which the sheets are overlapped in full contact with each other, but is a concept that includes a state in which parts of the sheets overlap. For example, the end sheets 11F are stacked such that a portion of one end in the longitudinal direction of the back sheet 6 touches a portion of the cover sheet 4. The diaper 1 is formed by stacking a back sheet 6 and a top sheet 9 with an absorbent body 8 between them, as well as a cover sheet 4, end sheets 11F and 11R, an inner cover sheet 5, and side sheets 10L and 10R. , it can be said that it has a laminate in which a plurality of these sheets are stacked.

Here, the diaper 1 according to this embodiment is a pants-type disposable diaper. The pants-type diaper 1 is assumed to be removed from the wearer's crotch by peeling off the side seal parts 3SL and 3SR shown in FIG. 1 when the wearer takes it off or when the wearer takes it off himself. . Generally, it is assumed that the side seal parts 3SL and 3SR are pulled and peeled off from the ventral side (front body region side) with the ventral side of the diaper 1 facing upward. Therefore, in the diaper 1 according to the present embodiment, at least one of the longitudinal ends of the side seal portions 3SL and 3SR is located on the front body region 1F side in a steady state. The steady state is, for example, a state 1 minute after the trunk opening 2T is pulled in the width direction to the maximum length for 10 seconds and then the external force is removed. The steady state can be regarded as the state of the diaper 1 in the worn state. Further, the steady state may be a state in which the diaper 1 is folded along a fold line in the width direction of the crotch region 1B (usually in a state in which it is stored in a package).

In the diaper 1 according to the present embodiment, the side seal parts 3SL and 3SR are located on the front body region 1F side, so when the side seal parts 3SL and 3SR are peeled off to the ventral side and the back side, the side seal parts 3SL and 3SR are It is easy to visually recognize the starting point for peeling off the 3SR, and it is possible to peel off the 3SR by pinching the exterior body on the dorsal side and ventral side of the starting point while wearing the 3SR and pulling it from the ventral side. In this way, the diaper 1 according to the present embodiment can include the side seal parts 3SL and 3SR that are easy to pull and peel off from the abdominal side.

<Example 1>
Next, Example 1 of this embodiment will be described. FIG. 4 is a plan view schematically showing the diaper 1 according to this embodiment in a state where it is unfolded and stretched. In this embodiment, in order to arrange the side seal portions 3SL and 3SR on the front body region 1F side in a steady state, the exterior body on the front body region 1F side is wider in the width direction than the exterior body on the back body region 1R side. Form the length short. Thereby, when the side seal parts 3SL and 3SR are formed, the side seal parts 3SL and 3SR can be arranged on the front body region 1F side.

<Example 2>
Next, Example 2 of this embodiment will be described. In this embodiment, the side seal portions 3SL and 3SR are arranged on the front body region 1F side by making the thread rubber 4F3 higher than the draft rate of the thread rubber 4R3. Here, the draft rate (%) of the rubber thread is expressed as a percentage obtained by dividing the length (cut length) when the rubber thread is assembled into a diaper by the natural length of the rubber thread. The rubber thread is incorporated into the diaper 1 in a stretched state in order to exhibit contractile force. Therefore, the draft rate becomes a value larger than 100%.

The elastic force of the rubber thread can be increased by increasing the draft rate. By making the elastic force of the rubber thread 4F3 arranged on the side of the front body region 1F larger than the elastic force of the rubber thread 4R3 arranged on the side of the back body region 1R, the side seal parts 3SL and 3SR are attached to the front body region 1F. It can be pulled to the side, and the side seal parts 3SL and 3SR can be arranged on the front body region 1F side.

<Example 3>
Next, Example 3 of this embodiment will be described. In this embodiment, the rubber thread 4F3 is provided so as to cross the crotch region 1B in the width direction without cutting the rubber thread 4F3 at the crotch region 1B, and the rubber thread 4R3 is cut at the center of the crotch region 1B. However, by not having a contraction force in the region overlapping with the absorbent body 8 when viewed in the thickness direction, the outer body is contracted toward the center in the width direction on the front body region 1F side than on the back body region 1R side, The crotch side end portions of the side seal portions 3SL and 3SR in the longitudinal direction can be arranged on the front body region 1F side. In addition, in this example, the length of the outer body on the front body region 1F side and the outer body on the rear body region 1R side in the width direction of the diaper 1 is substantially the same.

The left and right rubber threads 4R3 may be arranged so that the rubber threads 4R3 do not have a contractile force in at least part of the region overlapping with the absorbent body 8 when viewed in the thickness direction. For example, the rubber thread 4R3 may have a contractile force intermittently in the region overlapping with the absorbent body 8, or may not have a contractile force at the center in the width direction, but may have a contractile force outside the center. You can also For example, by disposing the thread rubber 4R3 intermittently in the region overlapping with the absorbent body 8, the contractile force can be intermittently exerted in the region.

Here, by adjusting the length between the left and right rubber threads 4R3 (hereinafter referred to as "the width between the rubber threads 4R3"), it was confirmed that the side seal parts 3SL and 3SR could be arranged on the front body region 1F side. The conditions for the rubber threads 4F3 and 4R3 were as follows. Note that the width between the rubber threads 4R3 is the width of the portion between the left and right rubber threads 4R3 where no rubber thread 4R3 exists.
(1) The numbers of rubber threads 4F3 and 4R3 were 2, 3, 4, and 5.
(2) The thicknesses of the rubber threads 4F3 and 4R3 were 620 dtex, 780 dtex, 940 dtex, and 1240 dtex.
(3) The draft ratio (%) of the thread rubber 4F3, 4R3 was set to 160%, 180%, 200%, 220%, 240%, and 260%. Note that the draft rate (%) of the rubber thread is expressed as a percentage of the length (cut length) when the rubber thread is assembled into a diaper divided by the natural length of the rubber thread. The rubber threads 4F3 and 4R3 are incorporated into the diaper 1 in a stretched state in order to exhibit contractile force. Therefore, the draft rate becomes a value larger than 100%.
The results of checking all combinations of conditions (1) to (3) are shown in Table 1 below. In addition, in all conditions, the width of the absorber 8 between the left and right rubber threads 4R3 was such that the width of the core wrap sheet 7 was 180 mm, and the width of the absorbent core 8c was 100 mm.

As shown in Table 1, by setting the width between the rubber threads 4R3 to 40 mm to 200 mm, the side seal portions 3SL and 3SR can be positioned on the ventral side. In addition, when the width between the rubber threads 4R3 is narrow, the rubber threads 4R3 do not have a contractile force in at least a part of the region overlapping with the absorber 8 when viewed in the thickness direction. The widthwise inner side of the rubber thread 4R3 may extend to a position where it overlaps the absorbent core 8c when viewed in the thickness direction.

<Example 4>
Next, Example 4 of this embodiment will be described. In this embodiment, the rubber thread 4F3 has a larger width direction component of the diaper 1 than the rubber thread 4R3. As a result, the exterior body is contracted closer to the center in the width direction on the front body region 1F side than on the back body region 1R side, and the crotch side ends of the side seal portions 3SL and 3SR in the longitudinal direction are arranged on the front body region 1F side. be able to.

In addition, it is preferable that the lower (crotch side) end of both ends of the side seal parts 3SL and 3SR in the longitudinal direction is arranged closer to the front body region 1F than to the back body region 1R. When the wearer peels off the side seal parts 3SL and 3SR, when the wearer grasps the lower end of the side seal parts 3SL and 3SR, the arm moves from an extended state to a bent state, allowing the wearer to move from the bottom to the top. This is because the side seal portions 3SL and 3SR can be peeled off. With this configuration, even an elderly person (elderly person) who is a care recipient can easily peel off the side seal portions 3SL and 3SR. Conversely, if the upper end of the longitudinal ends of the side seal portions 3SL, 3SR is placed closer to the front body region 1F than the back body region 1R, the wearer himself/herself can easily attach the side seal portions 3SL, 3SR to the front body region 1F side. When peeling off the side seal parts 3SL and 3SR, it is easier to hold the upper ends of the side seal parts 3SL and 3SR than the lower ends. It is necessary to move the side seal parts 3SL and 3SR from a bent state to an extended state, making it difficult to peel off the side seal parts 3SL and 3SR.

In addition, in this embodiment, the exterior body on the front body region side (front body exterior body) and the exterior body on the back body region side (back body exterior body) are integrally formed, but the exterior body on the front body region side The exterior body and the exterior body on the rear body region side may be provided separately.

<Example 5>
Next, Example 5 of this embodiment will be described. FIG. 5 is a plan view of the diaper 1 in an expanded and stretched state. Note that the same constituent elements as those of the first embodiment described above are given the same reference numerals, and the explanation thereof will be omitted.

In the area where the thread rubber 4F3 crosses from side to side in the crotch area 1B on the front body side, the inner cover sheet 5 and the absorbent core 8 are not bonded together (referred to as a non-bonded area 15). Actually, in the non-adhesive region 15, the inner cover sheet 5 and the back sheet 6 are non-adhered. In this embodiment, the non-adhesive area 15 is provided throughout the overlapping area of the crotch area 1B where the thread rubber 4F3 and the absorbent core 8 overlap. The non-adhesive area 15 is provided over the entire width of the interior body including the backsheet 6.

Moreover, FIG. 5 illustrates the adhesive portion between the interior body and the exterior body. The diaper 1 includes a first adhesive part 30, a second adhesive part 31 (an example of the "adhesive part" of the present disclosure), and a third adhesive part 32 as adhesive parts that adhere the inner body and the outer body.

The first adhesive part 30 is arranged on the front side of the non-adhesive area 15, and includes a plurality of linear adhesive parts that extend in the width direction of the diaper 1 and are spaced apart from each other in the longitudinal direction of the diaper 1. It has 30A. The plurality of linear adhesive parts 30A are formed by applying hot melt adhesive between the inner cover sheet 5 and the back sheet 6, which are between the exterior body and the interior body. Note that the plurality of linear adhesive portions 30A are formed to have a width slightly narrower than the entire width of the interior body.

The second adhesive portions 31 are disposed on the rear side (inseam side) of the non-adhesive area 15, and are provided in plurality extending in the width direction of the diaper 1 and spaced apart from each other in the longitudinal direction of the diaper 1. It has a linear adhesive part 31A. The second adhesive part 31 is an adhesive part that adheres the outer body and the inner body in the crotch region 1B. The plurality of linear adhesive parts 31A are formed by applying hot melt adhesive between the inner cover sheet 5 and the back sheet 6, which are between the exterior body and the interior body. The plurality of linear adhesive parts 31A are formed to have a width narrower than the entire width of the interior body, and a non-adhesive area where the interior body and the exterior body are not adhesive is provided outside the linear adhesive parts 31A in the width direction. 16L and 16R are provided.

The third adhesive part 32 is disposed on the rear side of the second adhesive part 31 and includes a plurality of linear shapes extending in the width direction of the diaper 1 and spaced apart from each other in the longitudinal direction of the diaper 1. It has an adhesive part 32A. The plurality of linear adhesive parts 32A are formed by applying hot melt adhesive between the inner cover sheet 5 and the back sheet 6, which are between the exterior body and the interior body.
Note that the plurality of linear adhesive portions 32A are formed to have a width slightly narrower than the entire width of the interior body.

The diaper 1 according to the present embodiment includes a non-adhesive area 15 and a second adhesion part 31 provided with non-adhesive areas 16L and 16R on both sides, so that the outer body can be made widthwise by the thread rubber 4F3 in the left and right sections. While contracting inward in the direction, the exterior body is bent toward the non-skin surface side (downward) at the boundary between the non-adhesive region 15 and the linear adhesive portion 31A. In addition, since the second adhesive part 31 is provided on the crotch side of the non-adhesive area 15, the exterior body on the crotch side of the non-adhesive area 15 is suppressed from shrinking excessively, and the non-adhesive areas 16L, 16R The inner exterior body can be contracted inward in the width direction by the contraction force of the rubber thread 4F3. Therefore, on the front body region 1F side, the diaper 1 pulls the side seal parts 3SL, 3SR (see FIG. 1) formed at the widthwise ends of the exterior body inward in the width direction, and the longitudinal sides of the side seal parts 3SL, 3SR are pulled inward in the width direction. The crotch side end of the direction can be arranged on the front body region 1F side.

In addition, the exterior body in the non-adhesive region 15 is lifted toward the front body region 1F side by the rubber thread 4F3, and the rubber thread 4F3 contracts inward in the width direction of the diaper 1, so that the outer body in the non-adhesive region 15 is wider than the absorbent body 8 in the non-adhesive region 15. The exterior body on the outside in the direction (regions 55L, 55R shown in FIG. 5) falls within the range where it overlaps with the absorbent body 8, or at least the exterior body is placed further outward in the width direction than the absorbent body 8 than in the case where the thread rubber 4F3 is not provided. The amount of protrusion will be reduced. For example, if the width of the absorbent body 8 on the non-adhesive region 15 that is lifted toward the front body region 1F side by the thread rubber 4F3 is wider than the position before being lifted, the exterior body will be more reliably accommodated within the width of the absorbent body 8. It becomes easier. Thereby, when the diaper 1 is worn, the left and right lower limb openings 2L, 2R are less likely to be blocked by the exterior body. Therefore, when the wearer puts on the diaper 1 by himself/herself, the left and right leg openings 2L and 2R are easily visible from the torso opening 2T, and when a caregiver or the like makes the wearer put on the diaper 1, the left and right leg openings 2L and 2R are easily seen from the outside. Since the lower limb openings 2L and 2R are easier to find, it becomes easier to wear the diaper 1. Furthermore, when the wearer puts his/her feet into the left and right lower limb openings 2L, 2R, the thumb becomes less likely to get caught on the exterior body.

Here, the arrangement relationship between the non-adhesive area 15 and the second adhesive part 31 will be explained. The plurality of linear adhesive parts 31A are arranged on the crotch side of the non-adhesive area 15. The rubber thread 4F3 contracts on the non-skin surface side of the non-adhesive area 15 and pulls the exterior body inward in the width direction. On the crotch side of the non-adhesive area 15, the exterior body and the interior body including the backsheet 6 and the absorbent body 8 are bonded to each other by a predetermined width from the widthwise center of the backsheet 6 by the linear adhesive portion 31A. , the exterior body is bent toward the non-skin side starting from the frontmost linear adhesive portion 31A. When the diaper 1 in this state is worn, the widthwise ends of the crotch region 1B are in a state along the wearer's inner thighs. In the diaper 1, the linear adhesive parts 31A are spaced apart from each other in the longitudinal direction in the crotch area 1B, so that the diaper 1 can feel soft against the skin, and furthermore, the widthwise end of the crotch area 1B is aligned with the inner thigh. , prevents the exterior body from digging into the skin. Thereby, the diaper 1 can suppress a decrease in the feeling of wearing in the crotch region 1B. Further, in the manufacturing process of the diaper 1, at the widthwise ends of the non-adhesive regions 16L and 16R, the outer case is cut to make it fluffy and bulky. Thereby, in the diaper 1, when the widthwise end of the crotch region 1B is placed along the inner thigh, the outer body can be made soft against the skin.

<Embodiment 2>
Next, a diaper 1 according to a second embodiment will be described. FIG. 6 is an example of an exploded perspective view of the diaper 1 according to the second embodiment. Note that the same constituent elements as those of the first embodiment described above are given the same reference numerals, and the explanation thereof will be omitted.

In the diaper 1 according to the present embodiment, between the back sheet 6 and the core wrap sheet 7, a rubber thread 4F7 is provided at the center in the width direction, extending in the longitudinal direction from the front body region 1F to the crotch region 1B. . The thread rubber 4F7 is bonded to the back sheet 6, and
It is adhered to the inner cover sheet 5 and the cover sheet 4 via. The rubber thread 4F7 exerts a force that causes the inner cover sheet 5 and the cover sheet 4 to contract in the longitudinal direction. Note that the region where the rubber thread 4F7 is provided is preferably a region where the absorber 8 and the inner cover sheet 5 are not bonded together. Note that the rubber thread 4F7 may be provided between the cover sheet 4 and the inner cover sheet 5.

Further, a rubber thread cover sheet 13 is arranged on the skin side of the rubber thread 4F7. The rubber thread cover sheet 13 is adhered to the back sheet 6, covering the rubber thread 4F7 from the skin side. The rubber thread cover sheet 13 is arranged between the rubber thread 4F7 and the absorbent body 8. Further, the thread rubber cover sheet 13 is not entirely bonded to the core wrap sheet 7 of the absorbent body 8. The thread rubber cover sheet 13 is disposed between the absorbent body 8 and the backsheet 6, is adhered to the backsheet 6, and is partially non-adhered to the core wrap sheet 7 of the absorbent body 8. This prevents the elastic force (contraction force) of the thread rubber 4F7 from acting too much on the absorbent body 8, and prevents the absorbent body 8 from deforming excessively. In addition, when replacing with the thread rubber 4F7 and using a band-shaped elastic member, the elastic member and the core wrap sheet 7 can be made non-adhesive in part without providing the thread rubber cover sheet 13. Further, in this embodiment, the thread rubber cover sheet 13 is formed to have the same length as the back sheet 6. The thread rubber cover sheet 13 may be formed with a length that matches the extending area of the thread rubber 4F7, or may be formed to be longer than the extending area of the thread rubber 4F7 and shorter than the back sheet 6. Good too. Note that a portion of the thread rubber cover sheet 13 is not bonded to the absorber 8. The thread rubber cover sheet 13 may be entirely non-adhered to the absorbent body 8.

FIG. 7 is an example of a diagram schematically showing a state in which the diaper 1 according to the second embodiment is unfolded and stretched. FIG. 7(A) schematically shows the internal structure of the diaper 1 in an expanded and stretched state when viewed from the left side. FIG. 7(B) is a plan view of the diaper 1 in an expanded and stretched state.

As shown in FIG. 7, the rubber thread 4F7 is provided at the center in the width direction between the back sheet 6 and the core wrap sheet 7, extending in the longitudinal direction from the front body region 1F to the crotch region 1B. Further, the absorbent core 8 is compressed in a linear manner so as to surround the rubber thread 4F7, and is displayed as a line 14 in FIG. 7 . The line 14 is provided in the width direction at the rear end. Further, the line 14 is bent outward in the width direction at the end on the front body region 1F side. Note that such compression of the absorbent body 8 is realized by embossing it with a roller, for example.

In the diaper 1 according to the present embodiment, as shown in FIG. 7, the thread rubber 4F7 is extended in the longitudinal direction from the front body region 1F to the crotch region 1B, and the thread rubber 4F7 is connected to the back sheet 6 and the core wrap sheet 7 (of the absorbent core 8). (partially). Therefore, the cover sheet 4 and the inner cover sheet 5 are contracted in the longitudinal direction. Moreover, since the absorbent body 8 is provided with lines 14 which are compressed regions, the bending of the lines 14 induces the absorbent body 8 to become convex toward the skin surface side. Therefore, the absorbent body 8 can reliably come into contact with the urethral opening. Therefore, urine excreted by the wearer can be prevented from leaking to the outside of the diaper 1. In addition, the same effect is produced when the thread rubber 4F7 is provided in the absorber 8.

<Embodiment 3>
Next, a diaper 1 according to a third embodiment will be described. FIG. 8 is an example of an exploded perspective view of the diaper according to the third embodiment. Note that the same constituent elements as those of the first embodiment described above are given the same reference numerals, and the explanation thereof will be omitted.

In this embodiment, the absorbent body 8 has a plurality of mats. The absorbent body 8 has an absorbent core 8c made of a plurality of mats, and a core wrap sheet 7 that wraps around the absorbent core 8c. In this embodiment, as shown in FIG. 8, the absorbent core 8c has an upper absorbent mat 8a and a lower absorbent mat 8b. The upper layer absorbent mat 8a has a substantially hourglass shape with a constricted portion, and the lower layer absorbent mat 8b has a rectangular shape. Further, the width of the lower absorbent mat 8b is approximately the same as the width of the constricted portion of the upper absorbent mat 8a. In this way, the absorbent core 8c may be formed by laminating two layers of absorbent mats.

The embodiments and modifications disclosed above can be combined.
