<1. Configuration of urine collection pad>
FIG. 1 is an overall view of a urine collection pad 1 according to an embodiment of the present invention. 2 is a cross-sectional view of the urine collection pad 1 viewed from the position II-II in FIG. The urine collection pad 1 is a urine absorbing article that is attached to a male genitalia (penis) and absorbs urine excreted from the male genitalia. The wearer wears the urine collection pad 1 and wears a diaper or underwear thereon. In the case of mild urination, only the urine collection pad 1 needs to be replaced without replacing the diaper or underwear, so that the economic burden on the wearer and the care burden on the caregiver are reduced.

  The urine collection pad 1 has a bag 10 that can accommodate male genitalia. The bag 10 is formed with an opening 10a for inserting a male instrument. As shown in FIG. 2, the bag body 10 includes a liquid-permeable top sheet 11 that constitutes the inner side surface, a liquid-impermeable back sheet 12 that constitutes the outer side surface, and both the sheets 11 and 12. And an absorbent body 13 interposed between them. When urine is excreted inside the bag body 10, the urine passes through the top sheet 11, but does not pass through the back sheet 12, and between the top sheet 11 and the back sheet 12, the absorbent body 13. Absorbed and retained.

  The top sheet 11 is made of a nonwoven fabric using hydrophilic fibers (cellulose, rayon, cotton, etc.), for example. Moreover, the top sheet 11 may be comprised with the nonwoven fabric which processed the surface of hydrophobic fiber (a polypropylene, polyethylene, polyester, polyamide, nylon, etc.) with surfactant, and was made liquid-permeable.

  The back sheet 12 is made of, for example, a water-repellent nonwoven fabric using hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon, etc.). The back sheet 12 may be made of a plastic film, or may be made of a plastic film and a highly flexible nonwoven fabric stuck on the outside thereof.

  The absorber 13 is configured by, for example, a granular polymer absorber. As shown in FIG. 2, in this embodiment, a polymer absorber is fixed to the inner side surface of the back sheet 12 via an adhesive (not shown), and a liquid that covers the polymer absorber on the inner side thereof. A transparent auxiliary sheet 14 is provided. Thereby, between the back seat | sheet 12 and the auxiliary sheet | seat 14, the polymer absorber is in the state distributed in the sheet form.

  The absorber 13 may be held between the top sheet 11 and the back sheet 12 without using the auxiliary sheet 14. The absorbent body 13 is a paper sheet such as tissue paper or a liquid-permeable non-woven sheet obtained by mixing a granular polymer absorbent body with an aggregate layer of pulverized hydrophilic fibers such as pulp fibers and cellulose fibers. You may be comprised by what was coat | covered with. However, in order to suppress the bulk of the absorbent body 13, it is desirable that the absorbent body 13 is composed of a polymer absorbent body without pulp.

  A folded portion 10b that is folded toward the inside of the bag body 10 is provided at the bottom of the bag body 10 (the portion on the opposite side of the opening 10a). As shown in FIG. 2, the top sheet 11, the auxiliary sheet 14, the absorber 13, and the back sheet 12 are folded toward the inside of the bag body 10 in the folding portion 10 b.

For this reason, the plurality of elastic members 15 generate an elastic force so as to shrink the opening 10a. On the other hand, the wearer or caregiver of the urine collection pad 1 can also widen the opening 10 a against the elastic force of the elastic member 15. For example, a polyurethane thread may be used for the elastic member 15, but a polyurethane film, natural rubber, or the like may be used.

  Moreover, as shown in FIGS. 1 to 3, an opening sheet 16 is provided in the opening 10 a of the bag body 10. The opening part sheet | seat 16 is stuck from the inner surface of the top sheet 11 to the outer surface of the back sheet | seat 12 via the adhesive agent (illustration omitted). The opening part sheet | seat 16 plays the role which reduces the irritation | stimulation with respect to skin of a wearer. The opening part sheet | seat 16 is comprised by the nonwoven fabric using a comparatively flexible fiber, for example.

  Further, as shown in FIG. 1, the bag body 10 is formed with a slit 10d that is cut from the edge of the opening 10a toward the bottom. Moreover, the fixing member 20 which fixes the opening part 10a according to the size of the male genitalia is provided at the edge of the slit 10d. The fixing member 20 includes a base sheet 21 having a base end attached to the edge of the slit 10 d of the bag body 10 and a male member 22 provided on the other end side of the base sheet 21. The male member 22 is made of, for example, a hook material of a hook-and-loop fastener, and can be attached to and detached from an arbitrary position on the surface of the opening sheet 16.

  The fixing member 20 does not necessarily have to attach the male member 22 to the opening sheet 16. For example, a female member (for example, a loop material of a hook-and-loop fastener) may be provided on the outer surface of the back sheet 12 near the opening 10a, and the male member 22 may be attached to the female member. An adhesive tape may be used as the male member 22.

  FIG. 4 is a development view of the urine collection pad 1. The urine collection pad 1 is formed from a substantially rectangular laminated body 2 in which a top sheet 11, an auxiliary sheet 14, an absorbent body 13, and a back sheet 12 are laminated in this order. When the urine collection pad 1 is manufactured, first, the laminate 2 is bent so that the top sheet 11 is inside and the folded portion 10b is formed at the bottom. Specifically, the laminated body 2 is folded in the vicinity of the folding line 2a extending in the width direction in the vicinity of the center in the longitudinal direction, and the laminated body 2 is valley-folded on the both sides of the folding lines 2b and 2c extending in the width direction.
