[0025] Adhering portions 27 and 28 are provided on the surface (inner surface side) facing the middle front abdominal portion 2c of the protruding portions 25 and 26 of the adhering pieces 22a and 22b, respectively. Also, an adhesion part 29 is provided. These adhering portions 27 to 29 correspond to the second adhering portion, and are attached to the attaching portion 23 provided in the middle front abdominal portion 2c in a detachable manner.

[0026] As a specific example of the adhering portion 23, a loop material having a nonwoven fabric, a woven fabric, a knitted fabric, etc. in which a fine loop structure is densely formed on the surface can be considered, and as a specific example of the adhering portions 27 to 29, A hook with a fine hook structure densely formed on its surface that detachably engages with the loop material Material is conceivable. More specifically, as the adhering portion 23, for example, a plastic film composite material having a nonwoven fabric, a woven fabric, or the like suitably used as a loop material of a hook-and-loop fastener on the surface is used. As the adhering portions 27 to 29, a plastic film having pins densely formed on the surface preferably used as a hook material of a hook-and-loop fastener is used. Alternatively, the outer surface side of the middle front abdomen 2c may be surface treated so that it functions as a loop material (attachment part 23) instead of attaching the loop material to the middle front abdomen 2c as a separate member! .

[0027] Further, as another specific example of the adhesion part 23, a surface treatment such as a plastic film that has been subjected to a surface treatment so as to be repeatedly peelable from the adhesive can be considered. Another specific example is an adhesive that can be used repeatedly.

[0028] Note that, according to the two specific examples of the attaching portion 23 and the attaching portions 27 to 29, the configuration on the attaching portion 23 side and the configuration on the attaching portions 27 to 29 side may be interchanged.

[0029] Further, the tip portions of the overhang portions 25, 26 of the adhering pieces 22a, 22b are knob portions 31 (see FIG. 4) in order to make the adhering pieces 22a, 22b easier to pinch. The knob portion 31 is not provided with attachment portions 27 and 28.

[0030] With such a configuration, when the protruding portions 25 and 26 of the right attached piece 22b are pinched and the attached portions 27 to 29 of the right attached piece 22b are peeled off from the attached portion 23 and pulled outward in the right direction, FIG. As shown, the right fracture part 17b is torn and the right front abdominal part 2b is integrated with the right adhering piece 22b and expands to the right side. Similarly, pinching the overhanging portions 25 and 26 of the left adhering piece 22a, peeling the adhering portions 27 to 29 of the left adhering piece 22a from the adhering portion 23, and pulling leftward outward, as shown in FIG. The fracture portion 17a is torn and the left front abdomen 2a is unfolded to the left together with the left adhering piece 22a. At this time, the middle front abdomen 2c is kept joined to the crotch 4 and remains outside the front crotch 4a.

For this reason, as shown in FIG. 1, in the disposable pants 1, the front abdomen 2 and the crotch part 4 are fixed to each other by the joint part 18 in the state at the time of product shipment before breaking the broken parts 17a and 17b. Therefore, it functions as a pant and can be easily raised and lowered in the same manner as a normal single-use pant without opening and closing means such as attached pieces 22a, 22b. Further, in this state, even if the attachment pieces 22a, 22b and the attachment portion 23 are disengaged, the front abdominal portion 2 and the crotch portion 4 do not separate. [0032] Further, when the disposable pants 1 are worn in a pants state, when the absorber 43 described later absorbs and holds excrement, the attachment pieces 22a and 22b are disengaged. The pants 1 can be easily removed from the pants 1 by breaking and unfolding the broken portions 17a and 17b. In this case, the pants 1 can be removed without taking off the wearer's clothes.

[0033] Further, after disengaging the attachment pieces 22a and 22b, breaking the fracture portions 17a and 17b, expanding the front abdomen 2, and confirming the contamination inside the pants 1, the attachment pieces 22a , 22b can be engaged with the attachment 23 to return the pants 1 to the original pants state. Further, even when the pants 1 and an auxiliary pad such as a urine collecting pad are used in combination, the attachment pieces 22a and 22b can be attached and detached to easily exchange the auxiliary pad.

[0034] Further, before wearing, the pants 1 are unfolded in the state shown in Fig. 5, placed on the wearer's buttocks, and closed in the order of Fig. 4, Fig. 3, and Fig. 1. 1 can be used like a normal disposable diaper. In this case, the pants 1 can be worn and removed without taking off the wearer's clothes.

[0035] Furthermore, in the present embodiment, the crotch portion 4 has a structure in which a middle front abdomen portion 2c is provided in a region in the width direction of the front crotch portion 4a, and the width of the front crotch portion 4a. The width D of the middle front abdomen 2c is shorter than the direction dimension X. Therefore, when performing the work of closing the state force when the left and right attachment pieces 22a, 22b are deployed to the left and right, the front crotch 4a is applied to the wearer's front abdomen, and the left and right attachment pieces 22a, 22b Can be attached to the attachment portion 23 of the middle front abdomen 2c, and the opening and closing operation can be performed smoothly.

[0036] Furthermore, the lateral width W1 of the attachment portion 23 is narrower than the lateral width D of the middle front abdominal portion 2c, and is provided in the lateral width direction region of the middle front abdominal portion 2c. The attachment part 23 to which 22a and 22b are fixed is further closer to the center and located on the front part of the abdomen of the wearer, and the front crotch part 4a is applied to the front part of the wearer. On the upper side, the left and right attachment pieces 22a, 22b can be fixed to the attachment portion 23 of the middle front abdomen 2c, and the opening / closing operation can be performed more smoothly.

[0037] <Crotch>

As shown in FIG. 5, the crotch part 4 has a substantially band-like shape that extends in the front-rear direction when expanded, and includes a front crotch part 4a, a rear crotch part 4b, and a middle crotch located between them. Part 4c It is mainly applied to the wearer's crotch, centering on the middle crotch 4c. As shown in FIGS. 5 to 7, the front crotch portion 4a is joined to the middle front abdominal portion 2c by the joining portion 18 in a state of being superimposed on the inner surface side of the middle front abdominal portion 2c. As shown in FIG. 5, the back crotch portion 4b is bonded and fixed to the back back portion 3 while being overlapped with the inner surface side of the back back portion 3. The leg elastic members 40a and 40b are attached to the left edge 16a and the right edge 16b of the crotch part 4 in a state of being extended in the extending direction of the edges 16a and 16b.

As shown in FIG. 8, the crotch portion 4 is configured by sandwiching an absorbent body 43 between a liquid-permeable top sheet 41 and a liquid-impermeable back sheet 42. The absorber 43 has a predetermined lateral width and spreads in a belt shape in the front-rear direction around the middle crotch 4c. On both the left and right sides of the absorbent body 43 on the inner surface side of the crotch portion 4, standing portions 44a and 44b extending along the extending direction of the crotch portion 4 are provided.

[0039] For example, the top sheet 41 is composed of a liquid-permeable nonwoven fabric or the like, and the knock sheet 42 is composed of a water-repellent nonwoven fabric or the like. The absorbent body 43 is, for example, a paper sheet such as tissue paper or a liquid-permeable nonwoven fabric sheet obtained by mixing a granular polymer absorbent body with a hydrophilic fiber aggregate layer such as pulverized pulp fiber or cellulose fiber. It is wrapped in a cover sheet and molded into a predetermined shape.

[0040] The portions of the top sheet 41 and the back sheet 42 that do not overlap with the absorber 43 are bonded to each other with an adhesive such as a hot melt adhesive. More preferably, as shown in FIG. 8, the width of the top sheet 41 is set to cover the skin side of the absorbent body 43 and slightly smaller than the width of the back sheet 42. It is joined to the backsheet 42 by a partial force adhesive that protrudes from front to back, right and left beyond 43, for example, hot melt adhesive. The left and right side sheets 45a, 45b constituting the upright portions 44a, 44b are bonded to the skin surface side of the portion of the knock sheet 42 that protrudes on both the left and right sides of the top sheet 41 by an adhesive such as a hot melt adhesive. Yes.

[0041] Further, both end edges in the front-rear direction of the side sheets 45a, 45b are joined to both end edges in the front-rear direction of the crotch part 4 by an adhesive 60, for example, a hot melt adhesive. The inner side edges of the side sheets 45a, 45b are fixed by heat welding (or ultrasonic welding) or the like at the sealing portion 47 so as to wrap around the elastic member 46 extending in the front-rear direction. Standing part 44a, 44 As for b, the inner side edge part of the left-right direction is shrunk by the contraction force of the elastic member 46, and as a result, as shown in FIG. 8, it stands up in the direction pressed against the wearer's skin.

In the present embodiment, as shown in FIG. 5, the left and right edges of the crotch 4 overlap the front abdominal part 2 and the waist part 3a of the back part 3 with the inclined sides 48a, 48b, 49a and 49b, and the width is gradually reduced toward the edge in the front-rear direction.

[0043] The inclined sides 48a and 48b prevent the front crotch part 2a from turning over, bending, and affecting the wearer's skin when the disposable pants 1 are raised and lowered smoothly. Can be raised or lowered.

[0044] Further, normally, in the region where the back portion 3 and the crotch portion 4 overlap, the contraction force of the back portion 3 tends to be weakened, but by forming the trim region by the inclined sides 49a and 49b, Then, the area of the stretchable part of the back part 3 gradually increases toward the upper side of the back part 3, and this makes it easy for the back part 3 to fit the back of the wearer.

[0045] As a modification of the configuration of the crotch portion 4, the absorbent body 43, which is not sandwiched between the sheets 41 and 42, is adhered to the skin side of the sheet 42, and the sheet 41 is omitted. It may be configured. Alternatively, a sheet having a sheet bonded to the front and rear ends of the absorber 43 may be used as the crotch portion 4, or the absorbent body 43 may be used as the crotch portion 4 using a large absorbent body 43. The steps 41 and 42 may be omitted.

[0046] <Back>

As shown in FIGS. 3 to 6, the back 3 has a shape in which the left and right lower corners of a substantially rectangular shape are cut off substantially obliquely when unfolded, and is hung from the waist on the back side of the wearer to the buttocks. It is applied to the part. For this reason, the back portion 3 is connected to the wearer's buttocks, which is connected to the lower portion of the waist portion 3a and the waist portion 3a, which is substantially horizontally long in plan view, mainly located in the waist portion on the back side of the wearer. And a substantially trapezoidal flange 3b in plan view. A waist elastic member 51 is attached to the upper edge portion 13 of the waistline portion 3a in a state of being stretched in the left-right direction, and a body elastic member 52 is provided in the other region of the waistline portion 3a. It is attached in the state extended in the left-right direction. A leg elastic member 53a is attached to the slanted edge 15a on the lower back of the back 3 in a state of extending along the edge 15a. On the edge 15b, the leg elastic member 53b extends along the edge 15b. Attached in an extended state. By contraction and extension of these elastic members 51, 52, 53a and 53b, the back portion 3 can easily fit the wearer's back and buttocks.

[0047] In particular, the collar portion 3b of the back portion 3 is configured so that the lateral width gradually decreases toward the lower side, and leg elastic members 53a, 53b are provided on the left and right inclined edges 15a, 15b. Therefore, when the edge portions 15a and 15b are contracted by the contraction force of the leg elastic members 53a and 53b, the flange portion 3b is easily fitted to the wearer's buttocks.

[0048] The leg elastic members 53a, 53b are attached to the heel part 3b continuously along the right and left inclined edges 15a, 15b and the lower edge part 15c of the heel part 3b, and then at least the crotch part 4 The portion 54 (see Fig. 6) that overlaps the absorber 43 is weakened. The weakening process is to make a no tension state by cutting the elastic member of the portion 54 or performing a process of weakening the contraction force. As a result, it is possible to prevent undesired distortion or the like from occurring in the absorber 43 due to the contraction force of the leg elastic members 53a and 53b, thereby reducing the absorption function.

[0049] <Other configurations and materials of each part>

The left and right elastic members 19a and 19b, the elastic members 20a and 20b, and the elastic members 21a and 21b provided in the front abdomen 2 are the same as in the case of the leg elastic members 53a and 53b, and the elastic members 20a, 20b, After 21a and 21b are installed in the front abdomen 2 continuously in the left-right direction via the middle front abdomen 2c, the weakening process is performed on the part located in the middle front abdomen 2c of the elastic members 20a, 20b, 21a and 21b. Is preferred 好.

[0050] Further, as the material configuration of the adhering pieces 22a and 22b, a nonwoven fabric, a woven fabric, a knitted fabric, and a plus chip material can be appropriately selected. Among these, a nonwoven fabric produced by a combination of one or a plurality of production methods among a spunbond method, an air-through method, a point bond method, a melt blow method, and an airlaid method is preferable. Further, the non-woven fabric produced by the spunbond method or the SMS method combining the spunbond method and the melt blown method with a basis weight of 30 to L00 g / m2 is also preferable in terms of strength. Most preferred is a nonwoven fabric produced by the spunbond method with a basis weight of 50 to 85 gZm2. The material can be appropriately selected from synthetic fibers such as polypropylene, polyethylene, polyester, and polyamide, and natural fibers such as pulp and silk. Preferably, synthetic fibers such as polypropylene, polyethylene, and polyester can be used. The main component is strong and suitable. is there. Most preferred is polyester fiber.

[0051] The elastic members 19a, 19b, 20a, 20b, 21a, 21b, 40a, 40b, 46, 53a, 53b are usually elastic elastic materials (polyurethane yarn, polyurethane film, natural rubber) used for disposable pants. Etc.) and is attached to a predetermined part of the pants 1 by an adhering means such as hot melt adhesive, heat welding, ultrasonic welding in the stretched state.

[0052] As described above, the disposable pants 1 according to the present embodiment have both functions of non-pants and diapers, and therefore can be easily raised and lowered when worn.

[0053] Further, the crotch portion 4 is located in the lateral width direction region of the front crotch portion 4a, and has a middle front abdomen portion 2c, and is located in front of the width direction dimension X of the front crotch portion 4a. The width D of the abdomen 2c is shorter. Therefore, when closing the left and right adhering pieces 22a, 22b from the left and right unfolded positions, place the front crotch 4a against the wearer's front abdomen and the left and right adhering pieces 22a, 22 The work of fixing 22b to the attachment part 23 of the middle front abdomen 2c can be performed, and the opening and closing work can be performed smoothly.
