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. If it is mild urination, only the urine collection pad 1 needs to be replaced without replacing the diaper or underwear, so 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 is interposed between a liquid-permeable top sheet 11 disposed on the inner side, a liquid-impermeable back sheet 12 disposed on the outer side, and both sheets 11, 12. And an absorber 13 to be used. 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 the present embodiment, a polymer absorbent is fixed to the inner side surface of the back sheet 12 via an adhesive (not shown), and the liquid permeable coating the polymer absorbent on the inside thereof. An 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. It may be coated 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.

  As shown in FIG. 2, the end portion of the back sheet 12 is folded inward in the vicinity of the opening 10 a of the bag body 10. A plurality of elastic members 15 are provided inside the folded portion of the backsheet 12. The plurality of elastic members 15 are arranged in parallel to each other along the edge of the opening 10a. 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.

  The plurality of elastic members 15 are fixed to the back sheet 12 by an adhesive (not shown) in a state where the elastic members 15 are extended from the natural length. For this reason, the plurality of elastic members 15 generate an elastic force so as to shrink the opening 10a. When the bag 10 is attached to the male genitalia, the inner surface of the bag 10 in the vicinity of the opening 10a is brought into close contact with the male genital by tightening the plurality of elastic members 15. That is, the plurality of elastic members 15 function as a tightening portion for fixing the bag body 10 to the male genitalia. 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.

  As shown in FIGS. 1 and 2, an opening sheet 16 is provided in the opening 10 a of the bag body 10. The opening sheet 16 is adhered to the top sheet 11 and the back sheet 12 via an adhesive (not shown) from the inner surface to the outer surface of the bag body 10 in the vicinity of the opening 10a. The opening sheet 16 is made of a water-repellent nonwoven fabric. More detailed features of the opening sheet 16 and functions performed by the opening sheet 16 will be described later.

  As shown in FIG. 1, the bag body 10 is formed with a slit 10 b that is cut from the edge of the opening 10 a toward the bottom. Moreover, the fixing member 20 which fixes the opening part 10a according to the size of the male genitalia is provided in the edge of the slit 10b. The fixing member 20 includes a base sheet 21 having a base end attached to the edge of the slit 10 b 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 locked to the female member. Further, instead of the male member 22, an adhesive tape may be used.

  FIG. 3 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 absorber 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 on the inner side with a folding line 2a extending in the width direction in the vicinity of the center in the longitudinal direction. And the urine collection pad 1 of the state of FIG. 1 and FIG. 2 is obtained by joining the both sides | sides of the laminated body 2 bent in the longitudinal direction with the heat seal | sticker etc. FIG.

  FIG. 4 is a view showing the urine collection pad 1 attached to the wearer. When wearing the urine collection pad 1, first, the wearer or caregiver widens the opening 10 a of the urine collection pad 1. And the bag body 10 is put on a wearer's male instrument in the state which opened the opening part 10a. When the wearer or caregiver removes his / her finger from the opening 10 a, the bag body 10 is temporarily fixed to the male genital by the elastic force of the elastic member 15. Thereafter, the wearer or caregiver attaches the male member 22 of the fixing member 20 to an appropriate position of the opening sheet 16. Thereby, the magnitude | size of the opening part 10a is adjusted according to the size of a male genitalia, and the urine collection pad 1 is firmly fixed with respect to a male genitalia.

  In particular, the urine collection pad 1 of the present embodiment has a slit 10b in the vicinity of the opening 10a, and a fixing member 20 is attached to the edge of the slit 10b. For this reason, the fixing member 20 can be pulled to overlap the edges of the slits 10b. Thereby, the magnitude | size of the opening part 10a can be adjusted, suppressing that a clearance gap generate | occur | produces between the opening part sheet | seat 16 and the male genitalia.

<2. About the structure near the opening>
FIG. 5 is a cross-sectional view of the urine collection pad 1 attached to the male genitalia 9 in the vicinity of the opening 10a. Hereinafter, the structure near the opening 10a of the urine collection pad 1 will be further described with reference to FIG.

  As shown in FIG. 5, the opening sheet 16 has a portion located inside the plurality of elastic members 15. When the urine collection pad 1 is attached to the male genitalia 9, the opening sheet 16 is brought into close contact with the entire circumference of the penis of the male genital 9 by tightening the elastic member 15. For this reason, even if urine flows backward from the inside of the bag body 10 toward the opening 10a as indicated by the white arrow U1 in FIG. 5, the urine is blocked between the male genitalia 9 and the opening sheet 16. It can be stopped.

  Further, as described above, the opening sheet 16 is made of a water-repellent nonwoven fabric. For this reason, there is almost no urine soaking into the opening sheet 16 itself. Therefore, leakage of urine from the opening 10a to the outside of the bag body 10 is prevented.

  In particular, in this embodiment, the inner side of all the elastic members 15 from the elastic member 15 arranged closest to the opening 10a to the elastic member 15 arranged closest to the bottom of the bag body 10 is the opening sheet 16. Covered. Thereby, the contact area of the male genitalia 9 and the opening part sheet | seat 16 is ensured widely. For this reason, in the urine collection pad 1 of this embodiment, the leakage of the urine from the opening part 10a is prevented more favorably.

  Moreover, the elastic member 15 fastens the male genitalia 9 through the opening part sheet | seat 16 which is a nonwoven fabric. For this reason, the irritation | stimulation to the skin by clamping | tightening is reduced. In particular, in the present embodiment, the back sheet 12 and the opening sheet 16 are disposed so as to overlap inside the elastic member 15. Thereby, more sufficient thickness is given to the inner side of the elastic member 15. For this reason, in the urine collection pad 1 of the present embodiment, the gap between the male genitalia 9 and the opening sheet 16 is further narrowed, and the skin irritation due to tightening is further reduced.

  In the present embodiment, the opening sheet 16 is provided as a separate sheet from the top sheet 11 and the back sheet 12. For this reason, the opening part sheet | seat 16 can be comprised with the raw material different from the top sheet | seat 11 and the back sheet | seat 12. FIG. For example, a nonwoven fabric suitable for contact with the skin and urine blocking can be used for the opening sheet 16.

  Moreover, in this embodiment, the opening part sheet | seat 16 is extended to the position inside the absorber 13 inside the bag body 10. FIG. That is, the inner end portion 16 a of the opening sheet 16 is positioned closer to the bottom side of the bag body 10 than the end portion 13 a of the absorbent body 13. For this reason, the urine blocked between the male genitalia 9 and the opening sheet 16 travels along the surface of the opening sheet 16 to the vicinity of the absorber 13 as indicated by a broken line arrow U2 in FIG. Led. In addition, oozing of urine from the vicinity of the end 13 a of the absorbent body 13 toward the opening 10 a is prevented by the water-repellent opening sheet 16.

  In the present embodiment, the opening sheet 16 extends to the outside of the bag body 10. Therefore, the edge 10c of the opening part 10a of the bag body 10 contacts a wearer's abdomen via the opening part sheet | seat 16 which is a nonwoven fabric. For this reason, irritation | stimulation to a wearer's skin by the contact of the bag body 10 is reduced.

  For the opening sheet 16, for example, a spunbond method, a melt blow method, an SMS method combining a spun bond method and a melt blow method, or a non-woven fabric produced by an air-through method can be used. As the material for the nonwoven fabric, for example, synthetic fibers such as polypropylene, polyethylene, polyester, polyamide and the like may be used.

  In particular, the air-through nonwoven fabric manufactured by the air-through method is manufactured by applying hot air treatment to the fiber sheet in which the fibers are intertwined, and thermally bonding the fibers together. Excellent in properties. Therefore, if an air-through nonwoven fabric is used for the opening sheet 16, the gap between the male genitalia 9 and the opening sheet 16 can be further reduced, and the irritation to the wearer's skin can be further reduced.

Moreover, in order to obtain the effect of narrowing the clearance gap between the male genitalia 9 and the opening sheet | seat 16, and reducing the irritation | stimulation to a wearer's skin, a weight per unit (weight per square meter) is high. It is preferable to use an air-through nonwoven fabric. For example, the basis weight of the air-through nonwoven fabric used for the opening sheet 16 is preferably 20 g / m ² or more, and more preferably 25 g / m ² or more.

<3. Modification>
Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.

  In the above embodiment, the water-repellent opening sheet 16 is provided separately from the top sheet 11 and the back sheet 12, but such an opening sheet 16 may not be provided. For example, like the urine collection pad 1A of FIG. 6, the opening sheet 16 may not be provided, and the back sheet 12 may be exposed in the vicinity of the opening 10a. Even with such a structure, urine can be blocked between the male genitalia and the back sheet 12 if the back sheet 12 is formed of a water-repellent nonwoven fabric. Moreover, since the back sheet 12 which is a nonwoven fabric contacts a male genitalia and an abdominal part, irritation | stimulation with respect to skin is also reduced.

  In particular, in the example of FIG. 6, the inner end 12 a of the backsheet 12 extends to a position inside the absorber 13. For this reason, the urine blocked between the male genitalia 9 and the back sheet 12 is guided to the vicinity of the absorber 13 through the surface of the back sheet 12. In addition, oozing of urine from the vicinity of the end 13 a of the absorbent body 13 toward the opening 10 a is prevented by the water-repellent back sheet 12.

  Moreover, in said embodiment, although the slit 10b and the fixing member 20 were provided in the urine collection pad 1, the slit 10b and the fixing member 20 do not need to be provided.

  Moreover, in said embodiment, the bag body 10 was comprised by bending the rectangular laminated body 2 and sealing the both sides, However, The bag body 10 is not necessarily the single laminated body 2. It may not be formed from. For example, the bag body 10 may be configured by joining a plurality of laminated bodies.
