The knob portion 31 is not provided with the attachment portions 27 and 28.

  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 attached piece 22b are peeled off from the attached portion 23 and pulled outward in the right direction, as shown in FIG. In addition, the right breaking portion 17b is torn and the right front abdominal portion 2b is unfolded on the right side together with the adhering piece 22b. Similarly, when the protruding portions 25 and 26 of the left attached piece 22a are pinched and the attached portions 27 to 29 of the attached piece 22a are peeled off from the attached portion 23 and pulled outward leftward, as shown in FIG. The broken portion 17a is torn and the left front abdominal portion 2a is integrated with the adhering piece 22a to expand on the left side. At this time, the middle front abdominal part 2c is kept in a state of being joined to the crotch part 4, and remains outside the front crotch part 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 by the joint part 18 in a state at the time of product shipment before the breaking parts 17 a and 17 b are broken. Therefore, it functions as a pant and can be easily raised and lowered in the same manner as a normal disposable pant without opening and closing means such as the attached pieces 22a and 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 are not separated.

  Further, when the disposable pants 1 are worn in the pants state, when the absorber 43 described later absorbs and holds the excrement, the engagement of the attachment pieces 22a and 22b is released, and the fracture portion 17a is released. , 17b can be broken and expanded to easily remove the pants 1 from the wearer. In this case, the pants 1 can be removed without taking off the wearer's clothes.

  Further, the engagement pieces 22a and 22b are disengaged to break the breaking portions 17a and 17b, the front abdomen 2 is expanded, and the contamination inside the pants 1 is confirmed, and then the attachment pieces 22a and 22b are attached. The pants 1 can be returned to the original pants state by engaging with one part of the portion 23. Even when the pants 1 and an auxiliary pad such as a urine pad are used in combination, the auxiliary pads can be easily exchanged by attaching and detaching the attachment pieces 22a and 22b.

  Moreover, before putting it on, the pants 1 are normally deployed by unfolding the pants 1 in the state shown in FIG. 5, placing them on the wearer's buttocks, and closing them in the order of FIGS. 4, 3, 1. It can also be used like a disposable diaper. In this case, the pants 1 can be worn and removed without taking off the wearer's clothes.

  Further, when the wearer's waist size is small when the attachment pieces 22a and 22b are disengaged and the broken portions 17a and 17b are used in a state of being broken, as shown in FIG. The pieces 22a and 22b can be fixed so as to overlap each other. That is, in the state where the attachment piece 22a (or 22b) on one side is fixed to the attachment portion 23 via the attachment portions 27 to 29, the attachment piece 22b (22a) on the other side is attached to the attachment piece 22a on the one side. (Or 22b), and can be fixed to the attachment portion 23 and the attachment portion 30 via the attachment portions 27-29.

As shown in FIGS. 5 to 7, the front crotch portion 4 a is joined to the middle front abdominal portion 2 c by the joining portion 18 in a state of being superimposed on the inner surface side of the middle front abdominal portion 2 c. As shown in FIG. 5, the back crotch portion 4 b is bonded and fixed to the back portion 3 in a state of being overlapped with the inner surface side of the back portion 3. 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.

  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 with the middle crotch 4c as the center. On both the left and right sides of the absorbent body 43 on the inner surface side of the crotch portion 4, standing portions 44 a and 44 b extending along the extending direction of the crotch portion 4 are provided.

  For example, the top sheet 41 is composed of a liquid-permeable nonwoven fabric or the like, and the back 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 non-woven sheet coated with a mass obtained by mixing a granular polymer absorbent body with a hydrophilic fiber aggregate layer such as pulverized pulp fiber or cellulose fiber. Wrapped in a sheet and molded into a predetermined shape.

  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 by an adhesive, for example, a hot melt adhesive. More preferably, as shown in FIG. 8, the width of the top sheet 41 is set to cover the skin surface side of the absorber 43 and slightly narrower than the width of the back sheet 42, and exceeds the absorber 43 of the top sheet 41. The portions that protrude from front to back and from side to side are joined to the back sheet 42 by an adhesive, for example, a hot melt adhesive. Left and right side sheets 45a and 45b constituting upright portions 44a and 44b are joined to the skin surface side of the portion of the back sheet 42 that protrudes from the left and right sides of the top sheet 41 by an adhesive, for example, a hot melt adhesive. .

  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 portion 4 by an adhesive 60, for example, a hot melt adhesive. The inner side edges of the side sheets 45a and 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. The standing portions 44a and 44b are erected in the direction in which the inner side edge portion in the left-right direction is contracted by the contraction force of the elastic member 46, and thereby pressed against the skin of the wearer as shown in FIG.

  Moreover, in this embodiment, as shown in FIG. 5, in the overlapping part which overlaps with the waist part 3a of the front abdominal part 2 and the back part 3 in the crotch part 4, the right and left edges are inclined sides 48a, 48b, 49a, 49b. The lateral width is gradually reduced toward the edge in the front-rear direction.

  The inclined sides 48a, 48b can prevent the front crotch portion 2a from being caught and turned up, bent, or affected on the wearer's skin when the disposable pants 1 are raised and lowered, and can be raised and lowered smoothly. .

  Usually, 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. However, by forming the trim region by the inclined sides 49a, 49b, The area of the stretchable portion gradually increases toward the upper side of the back portion 3, and this makes it easier for the back portion 3 to fit the back of the wearer.

  As a modified example of the configuration of the crotch portion 4, the absorbent body 43 is not sandwiched between the sheets 41 and 42, but the absorbent body 43 is attached to the skin surface side of the sheet 42, and the sheet 41 is omitted. Also good. Or what joined the sheet | seat to the front-and-back edge part of the absorber 43 may be used as the crotch part 4, the absorber 43 is used as the crotch part 4 using the large sized absorber 43, and the sheet | seat 41, 42 may be omitted.

<Back part>
As shown in FIGS. 3 to 6, the back portion 3 has a form in which the left and right lower corners of a substantially rectangular shape are cut off obliquely when unfolded, and is hung from the waist portion on the back side of the wearer to the buttocks. It is applied to the part. For this reason, this back part 3 is connected to the lower part of the wearer's buttocks on the lower part of the waistline part 3a in a plan view substantially in the shape of a horizontally long belt mainly located in the waistline part on the back side of the wearer and the waistline part 3a. And a substantially trapezoidal flange portion 3b in plan view. A waist elastic member 51 is attached to the upper edge 13 of the waistline portion 3a in a state where the waist elastic member 51 is extended in the left-right direction. It is attached in a stretched state. A leg elastic member 53a is attached to the inclined edge 15a diagonally to the lower left of the back portion 3 in an extended state along the edge 15a. The leg elastic member 53b is attached to the edge 15b in a state of being extended along the edge 15b. 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.

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

  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 the absorber of at least the crotch part 4 A weakening process is applied to a portion 54 (see FIG. 6) that overlaps 43. 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. This prevents an undesired distortion or the like in the absorber 43 due to the contraction force of the leg elastic members 53a and 53b, thereby preventing the absorption function from deteriorating.
