[0009] Hereinafter, an embodiment of the present invention will be described. The embodiment described below is one aspect of the present invention, and is not intended to limit the technical scope of the present invention.

[0010] <Embodiment> In this embodiment, the longitudinal direction of a tape-type disposable diaper (an example of an "absorbent article" in the present application, hereinafter simply referred to as a "diaper") is the direction connecting the front body facing the wearer's abdomen and the rear body facing the back. Between the front body (one side in the longitudinal direction) and the rear body (the other side in the longitudinal direction) (at the center in the longitudinal direction), a crotch portion that is disposed under the wearer's crotch (disposed opposite the crotch) is located in a connected manner. In addition, when the diaper is worn by a wearer (hereinafter abbreviated as "worn state"), the side facing the wearer's skin (the inner side when worn) is the skin-facing side, and the opposite side to the skin-facing side (the outer side when worn) is the non-skin-facing side. Furthermore, the direction connecting the skin-facing side and the non-skin-facing side is the thickness direction, and the direction perpendicular to both the longitudinal direction and the thickness direction is the width direction. In addition, the view from the thickness direction is the plan view. The diaper has a length along the longitudinal direction corresponding to the front-rear direction of the wearer, and a length along the width direction perpendicular to the longitudinal direction. In addition, terms related to directions used in this application refer to directions that correspond to the front, back, left and right of the wearer when the garment is worn. For example, the left and right direction in this application refers to the direction that corresponds to the left and right of the wearer when the garment is worn.

[0011] Fig. 1 is an external perspective view of a diaper 1 according to an embodiment. The diaper 1 has a longitudinal length of 500 mm or more and 1100 mm or less. Such a diaper 1 is suitable for adults. The diaper 1 has a crotch region 1B which corresponds to the crotch covering the pubic area of ​​a wearer when worn, a front body region 1F which is located in front of the crotch region 1B and corresponds to the waist of the wearer's abdomen, and a back body region 1R which is located behind the crotch region 1B and corresponds to the waist of the wearer's back. The left and right edges of the rear body region 1R are provided with a mechanical fastener (an example of an "adhesive portion" in the present application) 16 on the wearer's skin side, a front patch (an example of an "adhered portion" in the present application) 2F provided in the front body region 1F and looped on the non-skin side, and tapes (an example of a "tape" in the present application) 2L1, 2L2, 2R1, 2R2 that can be attached with the mechanical fastener 16 are provided. When the tapes 2L1, 2L2, 2R1, 2R2 are attached to the front patch 2F with the front body region 1F positioned on the wearer's abdomen and the rear body region 1R positioned on the wearer's back, the diaper 1 is fixed to the wearer's body in a state surrounding the wearer's waist circumference and thighs. Since the diaper 1 is fixed to the wearer's body in this manner, the wearer can freely change his or her body position while wearing the diaper 1. The non-skin facing sides of the tapes 2L1, 2L2, 2R1, and 2R2 are looped in the same manner as the non-skin facing side of the front patch 2F, so that the tapes 2L1, 2L2, 2R1, and 2R2 can be overlapped on the front patch 2F.

[0012] In order to prevent the formation of gaps between the diaper 1 and the wearer's skin that could serve as a liquid outflow path, the diaper 1 is provided with leg gathers 3AL, 3AR at locations along the wearer's leg circumference (thighs), three-dimensional gathers 3L, 3R are provided on the inside of the leg gathers 3AL, 3AR in the width direction of the diaper 1, and a waist gather 3W is provided at a location along the wearer's abdominal circumference. The leg gathers 3AL, 3AR, the three-dimensional gathers 3L, 3R, and the waist gathers 3W are brought into close contact with the wearer's skin by the elastic force of the elastic members. Thus, the liquid discharged from the wearer is absorbed into the absorbent body 6 without leaking out of the diaper 1. The elastic members may be selected from thread-like or strip-like rubber, etc., as appropriate.

[0013] Fig. 2 is an exploded perspective view of the diaper 1 according to the embodiment. 1 is a plan view of the diaper 1 according to the present embodiment. In plan view, the diaper 1 according to the present embodiment has a narrowed gourd shape in which the crotch region 1B is wider toward the front body region 1F and the back body region 1R than the crotch region 1B. Due to this planar shape, the diaper 1 easily fits the wearer's abdomen and buttocks when worn. The planar shape of the diaper 1 is not limited to a roughly gourd shape, and may be, for example, a roughly rectangular or roughly shuttlecock shape.

[0014] The diaper 1 includes a cover sheet 4 that forms an outer surface when worn. The cover sheet 4 is a sheet-like member having substantially the same planar shape (gourd shape) as the diaper 1 with constrictions 4KL, 4KR at the portions corresponding to the long sides, forming the exterior surface of the diaper 1, and having a rigidity that can withstand friction with clothing, etc., and is provided to reinforce the back sheet 5 described below and to improve the feel. The constrictions 4KL, 4KR are provided at the portions where the wearer's thighs are located. The cover sheet 4 is generally made of a nonwoven fabric made of synthetic fibers such as polypropylene, polyethylene, and polyethylene terephthalate. The cover sheet 4 is liquid impermeable and moisture permeable. The cover sheet 4 is not limited to a single-layer structure, and may be a multi-layer structure having an inner cover sheet and an outer cover sheet.

[0015] The diaper 1 comprises a back sheet 5, an absorbent body 6, and a top sheet 8, which are layered in this order on the wearer-facing surface of the cover sheet 4. The back sheet 5 and the top sheet 8 are all sheet-like members having a generally rectangular appearance, and the absorbent body 6 is a mat-like member having a generally gourd-shaped appearance. The back sheet 5, the absorbent body 6, and the top sheet 8 are all layered in this order on the cover sheet 4 with their longitudinal directions coinciding with the longitudinal direction of the cover sheet 4.

[0016] The back sheet 5 has a generally rectangular appearance. The back sheet 5 is a sheet formed of a thermoplastic water-impermeable resin such as a polyethylene film in order to suppress leakage of discharged liquid that has flowed into the absorbent body 6. The back sheet 5 has water repellency to prevent urine and moisture from seeping out of the diaper 1 and breathability to prevent the diaper from becoming stuffy when worn. The back sheet 5 may have a large number of minute ventilation holes formed therein to provide breathability.

[0017] In addition, the back sheet 5 of the diaper 1 has a center mark CM (see Figure 1) that runs continuously in the longitudinal direction at the center of the width direction, so that the wearer can align the center mark CM of the diaper 1 with the wearer's midline and wear the diaper in the correct position.

[0018] The diaper 1 includes a top sheet 8 disposed on the skin-facing side when worn. The top sheet 8 is the portion that contacts the wearer's skin when the diaper 1 is worn, and is a water-permeable sheet formed of a liquid-permeable material that allows liquids such as urine to pass through. The top sheet 8 may be made of a woven fabric, a nonwoven fabric, a porous film, or the like. The nonwoven fabric may be made of thermoplastic resin fibers such as polypropylene, polyethylene, polyester, or nylon that have been hydrophilized, or may be an air-through nonwoven fabric, a point-bonded nonwoven fabric, a spun-bonded nonwoven fabric, or a melt-blown nonwoven fabric.

[0019] An absorbent body 6 for absorbing liquid excreted by the wearer is disposed on the non-skin facing side of the top sheet 8. The longitudinal direction of the absorbent body 6 coincides with the longitudinal direction of the diaper 1.

[0020] The back sheet 5, absorbent body 6, and top sheet 8 all extend from the front body region 1F to the rear body region 1R. Therefore, when the wearer's genitals are covered with the cover sheet 4 in which the back sheet 5, absorbent body 6, and top sheet 8 are laminated, both ends in the longitudinal direction of the back sheet 5, absorbent body 6, and top sheet 8 are located on the wearer's ventral side and dorsal side. In other words, the wearer's genitals are covered by the absorbent body 6 from the wearer's ventral side to the dorsal side. Therefore, whether the wearer is in a supine position or a prone position, the discharged liquid is discharged through the top sheet 4. The absorbent body 6 comes into contact with the port 8 .

[0021] The diaper 1 also includes a pair of water-impermeable side sheets 9L, 9R arranged on both skin-facing sides of the diaper 1 in the width direction and extending along the longitudinal direction. The side sheets 9L, 9R are arranged such that their longitudinal ends coincide with the longitudinal ends of the top sheet 8. The side sheets 9L, 9R have fixing regions 9LA, 9RA arranged on their outer sides in the width direction. The fixing regions 9LA, 9RA are bonded to the top sheet 8, absorbent body 6, and back sheet 5, which are components arranged on the non-skin-facing sides, with a hot melt adhesive.

[0022] The side sheets 9L, 9R are bonded to the top sheet 8 with a hot melt adhesive, and the widthwise inner ends of the hot melt adhesive form the standing lines 3LL, 3LR (see FIG. 3), and the insides of the standing lines 3LL, 3LR form the upstanding three-dimensional gathers 3L, 3R. The widthwise inner ends of the side sheets 9L, 9R are free regions 9LB, 9RB which are the tips of the three-dimensional gathers 3L, 3R, and two rubber threads 3BL, 3BR which are thread-like elastic members are fixed in the vicinity of the free regions 9LB, 9RB by the hot melt adhesive in a stretched state in the longitudinal direction of the diaper 1. The side sheets 9L, 9R are bonded to the top sheet 8 on the widthwise inner side near the longitudinal ends, but the inside of the widthwise side of the hot melt adhesive is not bonded, and can stand up on the skin-facing side. When the elastic threads 3BL, 3BR contract and the three-dimensional gathers 3L, 3R inside the standing lines 3LL, 3LR stand up on the skin side, the free regions 9LB, 9RB become the tips on the skin side. The standing three-dimensional gathers 3L, 3R inhibit the movement of liquids and loose stools to the outside in the width direction of the three-dimensional gathers 3L, 3R, and suppress side leakage of these.

[0023] The entire longitudinal ends of the standing lines 3LL, 3RR of the side sheets 9L, 9R are bonded to the top sheet 8 by a hot melt adhesive to form the fixed parts 33L, 33R. The fixed areas 9LA, 9RA extend to the longitudinal ends of the side sheets 9L, 9R, so that the side sheets 9L, 9R are joined to the top sheet 8 over the entire longitudinal ends. The absorbent body 6 is thick because it is made of a plurality of laminated absorbent mats, and if the fixed parts 33L, 33R are provided at the locations where the absorbent body 6 overlaps, the biasing force of the rubber threads 3BL, 3BR is less likely to be transmitted to the fixed parts 33L, 33R. If the fixed parts 33L, 33R are provided at the locations where the absorbent body 6 does not extend, the fixed parts 33L, 33R can more easily follow the biasing force of the rubber threads 3BL, 3BR.

[0024] The free regions 9LB, 9RB located longitudinally outboard of the regions where the rubber threads 3BL, 3BR are arranged can be left unattached to the top sheet 8 even in the fixed portions 33L, 33R. By not adhering the free regions 9LB, 9RB to the top sheet 8, the biasing force of the free regions 9LB, 9RB is gently transmitted over the entire region of the fixed portions 33L, 33R, and it is possible to prevent the biasing force of the rubber threads 3BL, 3BR from concentrating on the longitudinal inward side of the fixed portions 33L, 33R.

[0025] Rubber threads 4LB, 4RB, which are thread-like elastic members, are fixed between the cover sheet 4 and the back sheet 5 on the non-skin facing side of the upright lines 3LL, 3LR with a hot melt adhesive in a stretched state in the longitudinal direction of the diaper 1, two for each width direction. The rubber threads 4LB, 4RB are elastic members for forming the leg gathers 3AL, 3AR shown in Fig. 1. The number of rubber threads 4LB, 4RB is not limited to two, and an appropriate number of rubber threads 4LB, 4RB may be provided depending on the elastic force (contractile force) required in the design of the diaper 1. By arranging the rubber threads 4LB, 4RB in a stretched state, the contraction of the rubber threads 4LB, 4RB allows the diaper 1 to fit around the legs of the wearer.

[0026] The cover sheet 4 has elastic threads 4CL and 4CR that prevent a gap from being formed between the diaper 1 and the wearer's waist circumference, and the elastic threads 4LB and 4RB are arranged on the inner side in the width direction of the diaper 1 and in the longitudinal direction of the diaper 1. The rubber threads 4CL, 4CR are provided in the direction along the diaper 1. The rubber threads 4CL, 4CR are provided in accordance with the elastic force (contractile force) required in the design of the diaper 1. In this embodiment, three rubber threads 4CL, 4CR are provided.

[0027] Moreover, the regions extending outward in the width direction of the standing lines 3LL, 3LR of the three-dimensional gathers 3L, 3R in a plan view are the ears 10L, 10R. In this embodiment, the ears 10L, 10R are formed in the front body region 1F and the back body region 1R. The upper absorbent mat 6A is disposed to include the outer sides in the width direction of the free regions 9LB, 9RB. The diaper 1 can increase the amount of liquid absorption by forming the upper absorbent mat 6A large while improving the cushioning properties in the ears 10L, 10R. The ears 10L, 10R may be formed in either the front body region 1F or the back body region 1R.

[0028] A pair of tapes 2L1, 2L2, 2R1, and 2R2 are arranged in the width direction at the outer ends in the width direction of the rear body region 1R. The tapes 2L1, 2L2, 2R1, and 2R2 have mechanical fasteners 16 on their skin-facing sides. The mechanical fasteners 16 can be attached onto the front patch 2F provided on the front body region 1F. By attaching the mechanical fasteners 16 onto the front patch 2F provided on the front body region 1F, the diaper 1 can be fixed to the wearer's body in a state in which it surrounds the wearer's waist and thighs.

[0029] Furthermore, a rubber thread 9ER for forming a waist gather 3W is provided between the back sheet 5 and the top sheet 8 at a position further toward the back than the end of the absorbent body 6. The rubber thread 9ER is provided between the back sheet 5 and the top sheet 8 with its longitudinal direction, which is the direction of expansion and contraction, oriented in the left-right direction of the diaper 1. Therefore, when the tapes 2L1, 2L2, 2R1, 2R2 provided on both the left and right sides of the rubber thread 9ER are attached to the front patch 2F on the abdominal side of the wearer, the rubber thread 9ER exerts a contractile force to bring the diaper 1 into close contact with the wearer and prevent the formation of a gap between the diaper 1 and the wearer's abdominal circumference.

[0030] Next, the structure of the absorbent body 6 will be described with reference to Figures 3 and 4. Figure 4 is a cross-sectional view of the diaper 1 according to the embodiment taken along line AA in Figure 3. In Figure 4, in order to make the internal structure of the diaper 1 easier to understand, each component is illustrated thicker than it actually is, but in reality the diaper 1 is very thin.

[0031] The diaper 1 includes an absorbent body 6 that absorbs and retains liquids such as urine. The absorbent body 6 is disposed on the non-skin-facing side of the top sheet 8, including the crotch region 1B, in order to absorb liquids discharged by the wearer. In this embodiment, the absorbent body 6 includes an absorbent core 6C containing an absorbent material, and a core wrap sheet 7 that covers the entire absorbent core 6C. The longitudinal direction of the absorbent body 6 coincides with the longitudinal direction of the absorbent core 6C, the longitudinal direction of the core wrap sheet 7, and the longitudinal direction of the diaper 1.

[0032] The absorbent core 6C has an upper absorbent mat 6A arranged on the top sheet 8 side and a lower absorbent mat 6B arranged on the non-skin-facing side. In plan view, the upper absorbent mat 6A has a gourd shape with the front body region 1F and the back body region 1R side being wider than the crotch region 1B and the crotch region 1B being narrowed. The lower absorbent mat 6B is arranged below (on the non-skin-facing side) the upper absorbent mat 6A when viewed from the top sheet 8 side, and has a rectangular shape (rectangular shape) whose long side is the longitudinal direction of the diaper 1 in plan view. The upper absorbent mat 6A and the lower absorbent mat 6B are laminated in the thickness direction so that their respective widthwise centers are approximately aligned. In plan view, the upper absorbent mat 6A is formed larger than the lower absorbent mat 6B. The longitudinal direction of the absorbent body 6 coincides with the longitudinal directions of the upper absorbent mat 6A and the lower absorbent mat 6B and the longitudinal direction of the diaper 1.

[0033] The crotch region 1B is sandwiched between the wearer's legs, and thus compressive pressure is applied inward in the width direction. On the other hand, in the front body region 1F and the back body region 1R, the weight of the wearer is applied, and pressure is applied in the thickness direction of the absorbent core 6C. To deal with these pressures, the crotch region 1B of the absorbent core 6C is provided with a constriction. Furthermore, the upper layer absorbent mat 6A and the lower layer absorbent mat 6B are laminated to give the absorbent core 6C in the crotch region 1B a high basis weight. This prevents the absorbent core 6C from losing its shape inward in the width direction in the crotch region 1B. Furthermore, in the front body region 1F and the back body region 1R, the width of the absorbent core 6C is widened to increase the area on which the weight is applied, thereby preventing the absorbent core 6C from losing its shape in the thickness direction. For this reason, it is preferable to make the absorbent core 6C approximately gourd-shaped.

[0034] The absorbent core 6C has a structure in which granular absorbent resin (polymeric water absorbent material) such as SAP (Super Absorbent Polymer), a hydrophilic polymer with a cross-linked structure that can absorb and retain water, is held in the gaps between short fibers of cellulosic 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 hydrophilically treated. These short fibers and SAP are examples of absorbent materials.

[0035] The SAP particles of this embodiment refer to a resin composition containing SAP in a granular form. The term "SAP-containing resin composition" as used herein includes both a composition consisting of SAP alone and a composition containing SAP as the main component and other substances to such an extent that they do not adversely affect water absorption. Examples of the "other substances" include additives such as surface modifiers added for the purpose of hydrophobizing the particle surface, and unreacted monomers remaining during the synthesis of SAP. The SAP particles can absorb about 10 to 100 times their own weight in liquid. For example, granular SAP particles having a diameter of about 0.1 to 0.5 mm before absorbing liquid may be used.

[0036] While SAP particles can gel and retain liquid, it takes a certain amount of time for the liquid to be absorbed. In the diaper 1, the short fibers slow down the discharged liquid while diffusing it inside the absorbent core 6C until the SAP particles absorb the liquid, and the discharged liquid is absorbed by a wide range of SAP particles, preventing the liquid from flowing back.

[0037] The absorbent core 6C may have a SAP layer (not shown) formed of a large number of SAP particles, and is disposed between the upper absorbent mat 6A and the lower absorbent mat 6B. The absorbent core 6C diffuses liquids such as urine through the lower absorbent mat 6B, and retains the liquid through the SAP layer and the SAP contained in the upper absorbent mat 6A.

[0038] The core wrap sheet 7 is a water-permeable sheet that wraps the entire absorbent core 6C, and more specifically, covers the skin-facing side, non-skin-facing side, and side of the absorbent core 6C. The core wrap sheet 7 maintains the shape of the absorbent core 6C when not in contact with discharged liquid, prevents it from losing its shape, and prevents the SAP particles contained in the upper absorbent mat 6A and the SAP particles contained in the SAP layer from escaping. In addition, SAP particles that have not absorbed moisture are hard sand-like, and if the SAP particles that have not absorbed moisture escape from the absorbent body 6 and come into direct contact with the wearer's skin, they may cause the wearer to feel uncomfortable. For this reason, the absorbent core 6C is wrapped in the core wrap sheet 7 to prevent the absorbent core 6C from losing its shape and to prevent the SAP particles from escaping outside the absorbent body 6.

[0039] In this embodiment, a pulp fiber sheet or a thin nonwoven fabric is used for the core wrap sheet 7. In this embodiment, tissue paper is used for the core wrap sheet 7. The core wrap sheet 7 is composed of an upper-layer core wrap sheet (not shown) disposed between the upper-layer absorbent mat 6A and the top sheet 8, and an upper-layer core wrap sheet (not shown) disposed on the non-skin-facing side of the lower-layer absorbent mat 6B, and an absorbent sheet (not shown) disposed on the non-skin-facing side of the lower-layer absorbent mat 6B. It may be formed from two sheets, a lower layer core wrap sheet (not shown) that covers the side surface of the core 6C and further covers the widthwise outer side of the upper layer core wrap sheet. When the core wrap sheet 7 is formed from two sheets, the upper layer core wrap sheet and the lower layer core wrap sheet can be formed from different materials. As an example, the upper layer core wrap sheet can be a pulp fiber sheet, and the lower layer core wrap sheet can be a resin nonwoven fabric. The core wrap sheet 7 may be formed from a single sheet.

[0040] The diaper 1 includes two grooves 6H provided in the absorbent body 6 and formed by squeezing the absorbent body 6 in the thickness direction. The grooves 6H are provided within the longitudinal length of the absorbent core 6C, and the front-rear ends are contained within the absorbent core 6C. The grooves 6H may be formed in a concave shape on the skin side by making the absorbent core 6C have less absorbent material such as short fibers than the other parts, or may be formed by penetrating the absorbent material forming the skin side of the absorbent core 6C in the thickness direction. The grooves 6H in this embodiment are formed in two lines approximately parallel to each other in the width direction around the crotch region 1B so as to extend in the longitudinal direction of the absorbent core 6C, and are formed by squeezing the absorbent core 6C formed of the upper absorbent mat 6A and the lower absorbent mat 6B. The discharged liquid such as urine flows into the grooves 6H, moves longitudinally along the grooves 6H, and is quickly absorbed over a wide longitudinal range of the absorbent body 6. Therefore, the diaper 1 according to this embodiment is provided with the grooves 6H, which allows the discharged liquid to be diffused quickly. Also, as shown in Fig. 3, the grooves 6H do not reach the longitudinal ends of the absorbent body 6. Therefore, the discharged liquid that has moved outward in the longitudinal direction does not reach the longitudinal ends of the absorbent body 6, but remains inside the grooves 6H and is gradually absorbed.

[0041] As shown in Fig. 3, in plan view, the two grooves 6H have a rectangular shape and are formed approximately parallel to each other with the crotch region 1B at the center. The width of the grooves 6H is 2 mm or more and 10 mm or less. The length of the grooves 6H is 150 mm or more and 250 mm or less. A diaper 1 having grooves 6H of this size is suitable for adults (nursing care). The grooves 6H may be formed in a polygonal shape, an elliptical shape, or a rectangular shape with both front and rear ends formed in an arc shape instead of a rectangular shape in plan view.

[0042] The two grooves 6H form valley folds when the diaper 1 is viewed from the skin-facing side, and when the diaper 1 is worn, the absorbent body 6 is folded in a W-shape in the crotch region 1B when viewed from the skin-facing side. As a result, the widthwise center portion of the absorbent body 6 sandwiched between the two grooves 6H rises convexly toward the skin-facing side and comes into contact with the wearer's skin. This makes it easier for the absorbent body 6 to come into contact with the urethral opening of the wearer at the raised portion, and the absorbent body 6 can effectively absorb and retain urine discharged from the urethral opening.

[0043] In addition, the location of the wearer's excretion hole is limited, and excreted liquid tends to be discharged in the same place, but there is a limit to the amount of excreted liquid that the absorbent body 6 can hold in the same place. The grooves 6H have the function of diffusing the excreted liquid generated by the wearer in the longitudinal direction of the absorbent body 6, and the excreted liquid diffused by the grooves 6H is absorbed in the parts of the absorbent body 6 that have excess holding capacity. The provision of the grooves 6H allows urine to be absorbed by the entire diaper 1, which reduces the frequency with which the diaper 1 needs to be changed.

[0044] FIG. 5 is an enlarged view of tape 2R1 according to this embodiment. FIG. 5(A) is an enlarged view of tape 2R1 in a state in which the extension length in the width direction of the diaper 1 is restricted. FIG. 5(A2) is a view of FIG. 5(A) seen from the cover sheet 4 side. FIG. 5(B) is an enlarged view of tape 2R1 in a state in which the extension length in the width direction of the diaper 1 is extended. FIG. 5(B2) is a view of FIG. 5(B) seen from the cover sheet 4 side. Tape 2R1 has the same configuration as tapes 2L1, 2L2, and 2R2, so the following description focuses on tape 2R1. Tape 2R1 is attached to side sheets 9L, 9R and the cover sheet 4, and is attached to the outer width direction ends of the diaper 1. The tape 2R1 extends over a range of 10 mm to 30 mm from the non-skin facing portion. The non-skin facing portion of the tape 2R1 is provided with an adherend portion 2R that has been looped in the same manner as the non-skin facing portion of the front patch 2F. Therefore, the tape 2R1 can be adhered over the non-skin facing portions of the tapes 2L1, 2L2, and 2R2.

[0045] The tape 2R1 has a first folded portion 11 extending linearly in the longitudinal direction, and a second folded portion 12 located away from the first folded portion 11 toward the widthwise center (the absorbent body 6 side) and extending linearly in the longitudinal direction.

[0046] The tape 2R1 has a temporary adhesive portion (one example of a "regulating portion" in the present application) 14 that regulates the length of the tape 2R1. The temporary adhesive portion 14 is formed by temporarily adhering the skin-facing side between the first folded portion 11 and the second folded portion 12 and the skin-facing side closer to the center in the width direction than the second folded portion 12 with a hot melt adhesive, heat seal, ultrasonic seal, or other bonding means, or a combination of these. Temporary adhesion refers to a state in which the materials that are bonded together are bonded to such an extent that they can be peeled off without breaking. The tensile strength of the temporary adhesive portion 14 is 3N or more and 10N or less. By providing the temporary adhesive portion 14 on the tape 2R1, it is possible to regulate the extension length of the tape 2R1 as shown in FIG. 5(A). It is also possible to release the temporary adhesion of the temporary adhesive portion 14 and use the tape 2R1 as shown in FIG. 5(B). In Fig. 5(B), the area where the skin-facing side between the first folded portion 11 and the second folded portion 12 overlaps with the skin-facing side closer to the center in the width direction than the second folded portion 12 is shown by hatching slanting downward to the right, and the area where the hot melt adhesive is applied is shown by hatching slanting downward to the left. In Fig. 5(B), the temporary adhesive portion 14 is formed by temporarily adhering adjacent areas in the width direction of the diaper 1 around the second folded portion 12. Alternatively, the temporary adhesive portion 14 may be formed by temporarily adhering areas spaced apart in the width direction of the diaper 1 around the second folded portion 12, or may be formed by temporarily adhering the skin-facing side of the cover sheet 4 and the skin-facing side of the tape 2R1.

[0047] The temporary adhesive portion 14 formed by temporarily adhering the skin-facing side between the first folded portion 11 and the second folded portion 12 and the skin-facing side closer to the center in the width direction than the second folded portion 12 is formed so as to be convex toward the non-skin-facing side of the wearer. When the diaper 1 is used with the temporary adhesive portion 14 temporarily adhered, the temporary adhesive portion 14 is provided so as to be convex toward the non-skin-facing side of the wearer, so that the temporary adhesive portion 14 does not directly contact the wearer's skin. Therefore, when the diaper 1 is worn, it is possible to prevent the temporary adhesive portion 14 from pressing against and compressing the wearer's skin.

[0048] The temporary adhesive parts 14 are formed so as to overlap the cover sheet 4 of the diaper 1 in the thickness direction. When the diaper 1 is used with the temporary adhesive parts 14 temporarily attached, the temporary adhesive parts 14 are provided so as to overlap the cover sheet 4 of the diaper 1 in the thickness direction so as to be convex on the non-skin side of the wearer. This separates the cover sheet 4 from the wearer's skin, thereby preventing the cover sheet 4 or the ends of the cover sheet 4 from pressing against and compressing the wearer's skin when worn.

[0049] The temporary adhesive portion 14 has an adhesive line 13. The adhesive line 13 is an area where adhesive is applied to temporarily adhere the temporary adhesive portion 14, and two adhesive lines 13 are provided linearly at a distance in the longitudinal direction in one temporary adhesive portion 14. The two adhesive lines 13 provided in the temporary adhesive portion 14 can be temporarily adhered by one adhesive line 13, and the extension length of the tape 2R1 can be regulated in two stages. Even if the temporary adhesion of one adhesive line 13 is peeled off by an unexpected force, the other adhesive line 13 can maintain the state of being temporarily adhered. Therefore, it is possible to prevent the diaper 1 from slipping off due to the abdominal circumference of the diaper 1 suddenly becoming longer than the abdominal circumference of the wearer.

[0050] FIG. 5(C) is a diagram showing an example of how the tape 2R1 is folded when the diaper 1 is in a distributed state. FIG. 5(C2) is a diagram of FIG. 5(C) as viewed from the cover sheet 4 side. FIG. 5(D) is a diagram showing the tape 2R1 folded when the diaper 1 is in a distributed state. 2) is a view of FIG. 5(D) seen from the cover sheet 4 side. The tape 2R1 has a third fold 15 that is located closer to the outer end of the tape 2R1 than the intermediate position between the first fold 11 and the outer end of the tape 2R1 in the width direction and extends linearly in the longitudinal direction. From the time of product manufacture to the time of product distribution, the diaper 1 is folded along the third fold 15 so that the mechanical fastener 16 faces inward. By folding the mechanical fastener 16 so that the mechanical fastener 16 faces inward, it is possible to prevent the mechanical fastener 16 from being exposed to the outside and being attached to other products. In addition, when the diaper 1 is folded along the third fold 15, the outer end of the tape 2R1 in the width direction is located at the outer end in the width direction than the first fold 11. Therefore, when the diaper 1 is put on, the fold formed along the third fold 15 is unfolded to expose the mechanical fastener 16 to the outside, and at the same time, it is possible to prevent the temporary adhesion of the temporary adhesion portion 14 from being released.

[0051] A tape-type disposable diaper is fixed to the wearer's body in a state where it surrounds the wearer's waist and thighs, so that the wearer can freely change his / her body position while wearing the diaper. However, since the tape is fixed to the wearer's body in a state where it surrounds the wearer's waist, it is necessary to adjust the length of the tape depending on the expansion of the waist after a meal and the wearer's body shape. Although the tape can be stretched by providing an elastic member, the tape stretches when the diaper is put on, so the length of the tape when the diaper is put on differs from the length of the tape when the diaper is put on. Therefore, there is a risk of the diaper being misaligned when the diaper is put on and when the diaper is put on.

[0052] On the other hand, in the present embodiment of the invention, a temporary adhesive portion 14 is provided on the tape 2R1, and the length of the tape 2R1 can be adjusted to a length suitable for the wearer's waist circumference by gradually releasing the temporary adhesive. Since the tape 2R1 does not stretch when putting on the diaper 1 or when the diaper is worn, the wearer can wear the diaper in an appropriate position.

[0053] Fig. 5(C) is a diagram showing an example of the folding of the tape 2R1 in the distributed state of the diaper 1. The used state of the tape 2R1 is the form shown in Fig. 5(A) and Fig. 5(B), but it is folded in the product shipping state and distributed state. By folding the tape 2R1 in the unused state, it is possible to prevent the mechanical fastener 16 from being exposed to the outside and from adhering to other products.

[0054] More specifically, the tape 2R1 in a distributed state is packaged with the mechanical fastener 16 folded along the third fold 15 in contact with the skin-facing side of the diaper 1, as shown in Fig. 5(C). At this time, the folded end of the mechanical fastener 16 does not overlap with the temporary adhesive portion 14. If the folded end of the mechanical fastener 16 does not overlap with the temporary adhesive portion 14, it is possible to avoid the temporary adhesive of the temporary adhesive portion 14 being released at the same time as the fold formed along the third fold 15 of the mechanical fastener 16 is unfolded during the operation of putting on the diaper 1.

[0055] When the diaper 1 is used, the tape 2R1 is spread so that the mechanical fastener 16 faces the skin as shown in FIG. 5(D), and the fold formed along the third fold 15 is unfolded as shown in FIG. 5(A), and the mechanical fastener 16 is spread and then worn in an appropriate wearing position. The appropriate wearing position is a position where the crotch part of the diaper 1 coincides with the crotch part of the wearer, and the center of the width of the diaper 1 coincides with the midline of the wearer. The proper positioning may be achieved by aligning the center mark CM or the like indicated on the diaper 1 with the midline of the wearer, or by visually checking the front, back, left and right of the diaper 1 and the wearer. At this time, the temporary adhesive part 14 is in a temporarily adhered state as shown in FIG. 5(A).

[0056] When it is necessary to widen the abdominal circumference while the temporary adhesive portions 14 are temporarily attached, the temporary adhesive lines 13 provided on the temporary adhesive portions 14 of the tapes 2L1, 2L2, 2R1, and 2R2 are released as shown in FIG. 5(B), so that the diaper 1 can be widened by a length corresponding to the abdominal circumference. The adhesive lines 13 may be released as many as necessary. By releasing only the required number of strips, the length of the diaper 1 corresponding to the waist circumference can be finely adjusted, and the diaper 1 can be worn in a more appropriate position.

[0057] In addition, since the non-skin facing side of the temporary adhesive portion 14 is provided with the attachment portion 2R that can be attached to the mechanical fastener 16, when a wearer with a short waist circumference wears the diaper 1, if the mechanical fastener 16 is attached onto the front patch 2F, it may not be possible to fasten the diaper 1 to the wearer's body in a state that it surrounds the wearer's waist circumference and thighs. In this case, the temporary adhesive portion 14 can be released from the temporary adhesive, and the mechanical fastener 16 can be attached beyond the front patch 2F to the attachment portion 2R arranged on the tape on the opposite side of the diaper 1 in the width direction, thereby enabling the diaper 1 to be fastened to the body.

[0058] Thus, the diaper 1 according to this embodiment comprises two pairs of tapes 2L1, 2L2, 2R1, 2R2 arranged with the mechanical fastener 16 attached to the front patch 2F provided in the front body region 1F at the widthwise outer end folded inward, and each of the two pairs of tapes 2L1, 2L2, 2R1, 2R2 is provided with a temporary adhesive portion 14 temporarily attached with an adhesive. When putting on the diaper 1, the mechanical fastener 16 is deployed, and the adhesive line 13 of the temporary adhesive portion 14 is released according to the wearer's abdominal circumference before putting on the diaper 1, so that the diaper 1 can be put on in an appropriate position.

[0059] <Experiment> Next, an experiment was conducted to verify the suitable tensile strength of the temporary adhesive of the temporary adhesive portion 14. The temporary adhesive of the temporary adhesive portion 14 is preferably strong enough to resist the expansion of the abdomen when worn and the force acting on the diaper 1 during the wearing operation. However, if the strength of the temporary adhesive is too strong, the temporary adhesive portion 14 provided on the skin side of the tape 2R1 may become frayed, which may cause the diaper 1 to feel uncomfortable against the skin. Therefore, an experiment was conducted to verify the suitable tensile strength of the temporary adhesive of the temporary adhesive portion 14 of the diaper 1. In the experiment, a diaper provided with a tape having a different tensile strength of the temporary adhesive was used. The wearer was made to wear the diaper without releasing the temporary adhesive of the temporary adhesive portion, and it was visually confirmed whether the temporary adhesive was released during the wearing operation or when the diaper was worn. After that, the temporary adhesive of the temporary adhesive portion was released, and it was visually confirmed whether the temporary adhesive portion was frayed.

[0060] Figure 6 is a table showing the experimental results. In this experiment, 11 diapers were created with tapes having different tensile strengths at the temporary adhesive parts. Prototype 1 has a tensile strength of 1N at the temporary adhesive parts. Prototype 2 has a tensile strength of 2N at the temporary adhesive parts. Prototype 3 has a tensile strength of 3N at the temporary adhesive parts. Prototype 4 has a tensile strength of 4N at the temporary adhesive parts. Prototype 5 has a tensile strength of 5N at the temporary adhesive parts. Prototype 6 has a tensile strength of 6N at the temporary adhesive parts. Prototype 7 has a tensile strength of 7N at the temporary adhesive parts. Prototype 8 has a tensile strength of 8N at the temporary adhesive parts. Prototype 9 has a tensile strength of 9N at the temporary adhesive parts. Prototype 10 has a tensile strength of 10N at the temporary adhesive parts. Prototype 11 has a tensile strength of 11N at the temporary adhesive parts.

[0061] The column "Temporary Adhesion Release" in FIG. 6 shows the results of an experiment verifying whether the temporary adhesive portion maintains a temporary adhesive state during the diaper putting on operation or during the wearing state involving movements such as breathing and walking. When the temporary adhesive portion does not maintain a temporary adhesive state during the diaper putting on operation or wearing state, it is indicated by "x", and when the temporary adhesive portion maintains a temporary adhesive state during the diaper putting on operation or wearing state, it is indicated by "o". When the temporary adhesive portion maintains a temporary adhesive state during the diaper putting on operation or wearing state, it is shown that the effect of preventing the temporary adhesive portion from being released by itself and regulating the length of the tape can be obtained. The experimental results showed that the temporary adhesive portion of prototype 1 and prototype 2 is released during the putting on operation or wearing state, and the temporary adhesive portion of prototypes 3 to 11 maintains a temporary adhesive state during the putting on operation or wearing state. Therefore, when the tensile strength of the temporary adhesive portion is 3N or more, it is considered that the temporary adhesive portion maintains a temporary adhesive state during the putting on operation or wearing state.

[0062] The column "fuzzing of temporary adhesive portion" in FIG. 6 shows the results of checking whether the temporary adhesive portion is fuzzed when the temporary adhesive portion is removed. In the table of FIG. 10, if fuzzing occurs in the temporary adhesive portion when the temporary adhesive portion is removed, it is indicated as "x", and if fuzzing does not occur in the temporary adhesive portion when the temporary adhesive portion is removed, it is indicated as "o". If fuzzing occurs in the temporary adhesive portion when the temporary adhesive portion is removed, it indicates that the temporary adhesive portion has a poor feel on the skin and reduces the wearing comfort. Referring to the experimental results, it was found that no fuzzing occurs in the temporary adhesive portion in prototypes 1 to 10, and only prototype 11 had fuzzing in the temporary adhesive portion. Therefore, if the tensile strength of the temporary adhesive portion is 10 N or less, it is considered that the wearing comfort of the wearer is not reduced by fuzzing of the temporary adhesive portion when the temporary adhesive portion is removed and the length of the tape is extended.

[0063] Judging from the above experiments comprehensively, the tensile strength of the temporary adhesive part 14 is preferably 3N or more, and more preferably 10N or less.

[0064] If the diaper 1 has a tensile strength of the temporary adhesive portion 14 within the above range, the temporary adhesive portion 14 restricts the extension length of the diaper 1 in the width direction, allowing the wearer to wear the diaper in an appropriate position without compromising the fit.

[0065] <Modification> Next, a diaper according to a modification of this embodiment will be described. In this embodiment, the adhered portion 2R is provided on the non-skin side of the mechanical fastener 16, but the adhered portion 2R may not be provided. The non-skin side of the mechanical fastener 16 may be a nonwoven fabric that is not looped, or may be made of a material that cannot be repeatedly adhered by the mechanical fastener 16. FIG. 7 is an enlarged view of the tape 2R1 of the diaper 1 according to the modification. FIG. 7(A) is an enlarged view of the tape 2R1 in a state in which the extension length in the width direction of the diaper 1 is restricted. FIG. 7(A2) is a view of FIG. 7(A) seen from the cover sheet 4 side. FIG. 7(B) is an enlarged view of the tape 2R1 in a state in which the extension length in the width direction of the diaper 1 is extended. FIG. 7(B2) is a view of FIG. 7(B) seen from the cover sheet 4 side. FIG. 7(C) is a view showing an example of folding the tape 2R1 in the diaper 1 in a distributed state. Fig. 7(C2) is a view of Fig. 7(C) seen from the cover sheet 4 side. Fig. 7(D) is a view of the diaper 1 in a distributed state, with the tape 2R1 unfolded. Fig. 7(D2) is a view of Fig. 7(D) seen from the cover sheet 4 side.

[0066] Providing the adherend portion 2R on the non-skin side of the mechanical fastener 16 enables overlapping application of tapes or cross application of tapes in a cross shape, improving wearability, but since the mechanical fastener 16 overlapping and affixing on the upper side (non-skin side) in the thickness direction in the overlapping application moves in conjunction with the mechanical fastener 16 affixed on the lower side (skin side) in the thickness direction, if the lower mechanical fastener 16 comes off, the upper mechanical fastener 16 may also come off. If the mechanical fasteners 16 overlap, the temporary adhesion of one of them can be released, allowing the mechanical fasteners 16 to be affixed to the front patch 2F without overlapping.

[0067] <Other embodiments> In this embodiment, the tape 2R1 is formed of a different material from the front body region 1F and the back body region 1R, but the tape may be extended outward in the width direction from the material forming the front body region 1F or the back body region 1R. In this case, the mechanical fastener 16 is provided at the outer end in the width direction of the front body region 1F or the back body region 1R.

[0068] In this embodiment, the mechanical fastener 16 is attached to the rear body region 1R, and the front patch 2F is attached to the front body region 1R. Although the mechanical fastener 16 is provided in the body region 1F, the front patch 2F may be provided in the front body region 1F and the front patch 2F in the back body region 1R.

[0069] In addition, in this embodiment, a mechanical fastener 16 is used as the adhesive portion, and a front patch 2F that can repeatedly engage with the mechanical fastener 16 is used as the adherend portion, but the adherend portion may be coated with an adhesive material that uses adhesive power, and the adherend portion may be capable of being repeatedly adhered by the adhesive power of the adhesive portion.

[0070] Although the temporary adhesive portion 14 in this embodiment is temporarily attached so as to be convex on the non-skin side, it may be temporarily attached so as to be convex on the skin side.

[0071] The embodiments and application examples thereof disclosed above can be combined with each other. [Explanation of symbols]
