It is the whole urine collection pad concerning a 2nd embodiment. It is a general view of the urine collection pad concerning a 3rd embodiment. It is an expanded view of a urine collection pad. It is the whole urine collection pad concerning a modification.

  Hereinafter, embodiments will be described with reference to the accompanying drawings.

<1. First Embodiment>
FIG. 1 is an overall view of a urine collection pad 100 according to the first embodiment. 2 is a cross-sectional view taken along line AA of the urine collection pad 100 shown in FIG. FIG. 3 is a development view of the urine collection pad 100. In the following description, a person who wears the urine collection pad 100 is referred to as a wearer, and a person who cares for the wearer to wear the urine collection pad 100 is referred to as a caregiver.

  The urine collection pad 100 is a urine absorbent article that is directly attached to the male genitalia (penis) P and absorbs urine excreted from the male genitalia P. The wearer wears the urine collection pad 100 and wears a diaper or underwear thereon. In the case of a small amount of urine, only the urine collection pad 100 needs to be replaced without replacing the diaper or the underwear, so the amount of use of the diaper or the underwear can be reduced. This reduces the financial burden on the wearer and the burden on the caregiver, and also contributes to environmental protection.

  The urine collection pad 100 has a bag 10 that can accommodate male genitalia. In the upper part of the bag body 10, an opening 10 </ b> P for inserting the male genitalia into the bag body 10 is formed. The direction (insertion direction) in which the male instrument is inserted into the urine collection pad 100 is the longitudinal direction of the urine collection pad 100, and the direction orthogonal to the insertion direction (orthogonal direction) is the width direction of the urine collection pad 100. .

  As shown in FIG. 2, the bag body 10 includes a liquid-permeable top sheet 11 that constitutes the inner surface thereof, a liquid-impermeable back sheet 12 that constitutes the outer surface, the top sheet 11 and the back sheet 12. And an absorber 13 interposed therebetween. The urine excreted inside the bag body 10 passes through the top sheet 11, but is absorbed by the absorbent body 13 without passing through the back sheet 12.

  The top sheet 11 is made of a nonwoven fabric using hydrophilic fibers (cellulose, rayon, cotton, etc.), for example. In addition, 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.). In addition, the back sheet 12 may be comprised with the plastic film, and may be comprised with the plastic film and the highly flexible nonwoven fabric affixed on the outer side.

  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. Absorbent body 13 is a paper sheet such as tissue paper or a liquid-permeable non-woven sheet obtained by mixing granular polymer absorbers 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 preferable that the absorbent body 13 is composed of a polymer absorbent body without pulp. Furthermore, it is preferable that the absorber 13 is composed only of a polymer absorber.

  As shown in FIG. 2, the end portion of the back sheet 12 is folded inward in the vicinity of the opening 10 </ b> P of the bag body 10. And the expansion-contraction part 15 comprised by the multiple elastic member 151 is provided inside the folded part of the back seat | sheet 12. As shown in FIG. The plurality of elastic members 151 are attached to the back sheet 12 with an adhesive or the like in a state where they are extended from their natural lengths.

  Since the elastic force that attempts to return to the natural length acts on the elastic member 151, the expansion / contraction part 15 biases the opening 10P to contract in the width direction. On the other hand, the wearer (or caregiver) of the urine collection pad 100 can also widen the opening 10 </ b> P against the elastic force of the elastic member 151. For example, a polyurethane thread can be used as the elastic member 151, but a polyurethane film, natural rubber, or the like may be used.

  As shown in FIG. 2, an opening sheet 16 is provided in the opening 10 </ b> P of the bag body 10. The opening sheet 16 is bridged from the inner surface of the top sheet 11 to the outer surface of the back sheet 12, and is attached to each sheet with an adhesive. The opening part sheet | seat 16 is comprised by the nonwoven fabric using the comparatively flexible fiber, for example. Since the opening sheet 16 having a relatively soft touch comes into contact with the skin of the wearer wearing the bag body 10, it is possible to reduce irritation to the skin due to the mounting of the bag body 10.

  Moreover, as shown in FIG. 1, the slit 17 cut | disconnected from the edge of the opening part 10P toward the bottom part 10B side is provided in one side part of the bag body 10. As shown in FIG. The slit 17 is provided with a fixing portion 2 for fixing the opening size of the opening portion 10P according to the size of the male genitalia.

  The fixing portion 2 includes a base material sheet 21 whose base end portion is attached to the slit 17 of the bag body 10, and a male member 22 provided at a portion on the other end side from the center of the base material 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. When the back sheet 12 is a non-woven fabric, the male member 22 can be attached to and detached from any position of the back sheet 12.

  Further, 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 10P, and the male member 22 may be attached to the female member. The male member 22 may be an adhesive tape.

  FIG. 3 is a development view of the urine collection pad 100. The urine collection pad 100 includes a top sheet 11, a substantially rectangular auxiliary sheet 14, a substantially rectangular absorbent body 13 that is approximately the same size as the auxiliary sheet 14, and a back sheet 12 that is substantially the same shape as the top sheet 11. The laminate 3 is laminated in this order. The laminated body 3 is composed of a rectangular portion and a trapezoidal portion that is adjacently disposed so that the lower base overlaps one side of the rectangular portion, and the upper half and the lower half have substantially the same shape. Have.

  When manufacturing the urine collection pad 100, the laminated body 3 is first bent so that the top sheet 11 may become inside. Specifically, the laminated body 3 is bent into a valley shape with a valley fold line 31 extending in the width direction as a boundary near the center in the longitudinal direction of the laminated body 3 shown in FIG. And the bag body 10 is comprised by joining the part (the seal | sticker joining area | region 4 and shown with the hatching of the oblique line) along the edge part of the folded laminated body 3 by a heat sealing machine. That is, at the upper end (and lower end) of the laminate 3, the portion sandwiched between the seal joining regions 4 on both sides forms the opening 10 </ b> P of the bag 10, and the portion on the valley fold line 31 of the laminate 3 is the bag. 10 bottom portions 10B are formed.

  As shown in FIG. 1, a widened portion 18 that extends outward in the width direction with respect to the opening 10 </ b> P is formed on one side inside the bag body 10. And the inner periphery of the bag body 10 becomes large gradually as it goes to the bag body 10 inside from the edge part of the opening part 10P. By configuring the bag body 10 in this manner, the urine storage volume of the bag body 10 is increased, and the inner periphery of the opening 10P does not need to be increased, so that the bag body 10 is easily detached from the male genitalia P. This can be suppressed.

  3, the width d1 of the absorber 13 in the width direction is the length in the width direction of the opening 10P (= between the seal joint regions 4 on both sides at the upper end (or lower end) of the laminate 3). The distance is equal to or less than d2 (that is, d1 ≦ d2). Therefore, the non-arrangement region 5R in which the absorber 13 is not arranged extends inside the bag body 10 so as to reach the bottom portion 10B (see FIG. 1).

  Moreover, as shown in FIG. 1, the absorber 13 is arrange | positioned under the opening part 10P. In other words, the absorbent body 13 is unevenly distributed on the seal joint region 4 side opposite to the widened portion 18 in the width direction of the bag body 10. Therefore, a wide non-arrangement region 5 </ b> R is formed on the widened portion 18 side of the absorber 13. In the non-arrangement region 5R, urine is not absorbed by the absorber 13. That is, the flow path of excreted urine is formed by the non-arrangement region 5R.

  FIG. 4 is a diagram illustrating a state where the urine collection pad 100 is attached to the male genitalia P. When attaching the urine collection pad 100 to a male genitalia, first, the wearer (or caregiver) opens the opening 10P of the bag body 10 with a finger or the like. And the bag 10 is covered with a wearer's male instrument in the state by which the opening part 10P was expanded. In this state, the wearer (or caregiver) releases his / her finger from the opening 10 </ b> P, so that the male genitalia is sandwiched between the stretchable portions 15 of the bag body 10 from both sides.

  Further, the wearer (or caregiver) adjusts the opening size of the opening 10P so as to match the size of the male genital P by attaching the male member 22 of the fixing portion 2 to an appropriate position of the opening portion sheet 16. To do. Thereby, the urine collection pad 100 is firmly fixed to the male genitalia P.

  In addition, as shown in FIG. 4, it is preferable that the urine collection pad 100 is worn so that the widened portion 18 side (that is, the side where the non-arrangement region 5R is provided) of the bag body 10 is close to the wearer. . Since the urine collection pad 100 is worn in this manner, the distal end portion (urethral orifice) of the male genitalia P is easily placed on the non-placement area 5R, and thus excreted urine passes over the non-placement area 5R. It becomes easy to reach the bottom 10B. Therefore, since it becomes easy to absorb urine in the wider range of the absorber 13, the urine absorption efficiency of the urine collection pad 100 is improved.

  In this embodiment, since the widened portion 18 is provided only on one side of the bag body 10, the wearer (or caregiver) can specify the direction in which the bag body 10 should be worn from the shape of the bag body 10. . Therefore, it becomes easy to wear the urine collection pad 100 in a preferable form as described above.

  The width d1 of the absorber 13 in the width direction is equal to or less than the length d2 in the width direction of the opening 10P. However, the length d1 of the absorber 13 in the width direction is the length of the opening 10P. d2 may be exceeded (that is, d1> d2). However, in order to allow the excreted urine to reach the bottom 10B, the length in the width direction of the non-arrangement region 5R (the distance between the side end of the absorber 13 and the seal joint region 4) is sufficient. It is desirable to be secured.

  As described above, according to the urine collection pad 100 of the present embodiment, the bag body 10 is prevented from expanding by making the inner circumference inside the bag body 10 larger than the inner circumference of the opening section. The internal volume can be increased. Thereby, while the sufficient amount of absorber 13 can be arrange | positioned inside the bag body 10, the non-arrangement area | region 5R which does not arrange | position the absorber 13 is also securable. Therefore, since the excreted urine easily flows toward the bottom of the bag body 10 through the non-arrangement region 5R, the urine absorption efficiency of the urine collection pad 100 is improved.

<2. Second Embodiment>
In the first embodiment, the widened portion 18 is provided on one side and the non-arranged region 5R serving as the flow path of urine excreted in the widened portion 18 is formed. It is not limited to this.

  FIG. 5 is an overall view showing a urine collection pad 100a according to the second embodiment. In the description of the present embodiment, elements having the same functions as those of the first embodiment are denoted by the same reference numerals and description thereof is omitted. The same applies to the following embodiments.

  On both sides of the bag body 10a constituting the urine collection pad 100a, widened portions 18a that extend outward in the width direction from the edge of the opening 10P are provided. And the absorber 13 of this embodiment is arrange | positioned in the approximate center of the urine collection pad 100a. Then, both sides of the absorber 13 are separated from the seal joint regions 4 on both sides by the same extent, and non-arrangement regions 5R are formed on both sides of the absorber 13.

  In the urine collection pad 100a, widened portions 18a are provided on both sides of the bag body 10a, and non-arrangement regions 5R are formed in these portions. Therefore, even when the urine collection pad 100a is worn so that either of the widened portions 18a is close to the wearer, the excreted urine easily reaches the bottom portion 10B through one of the non-arrangement regions 5R. Yes. Therefore, since it becomes easy to absorb urine in a wider range of the absorber 13, the urine absorption efficiency of the urine collection pad 100a is improved.

<3. Third Embodiment>
FIG. 6 is an overall view showing a urine collection pad 100b according to the third embodiment. FIG. 7 is a development view of the urine collection pad 100b. The bag body 10b which comprises the urine collection pad 100b is comprised by the substantially rectangular laminated body 3b shown in FIG. Similar to the laminated body 3 (FIG. 2), it is folded at the valley fold line 31b extending in the width direction in the vicinity of the center in the longitudinal direction, and the folded laminated body 3 is joined at the seal joining region 4 along the side end portion. Thereby, the bag body 10b is formed.

  In the present embodiment, the absorber 13 is arranged so that one of the distances (d3, d4) between the absorber 13 and the seal joint regions 4 on both sides is larger (here, d3> d4). Therefore, a wider non-arrangement region 5R is formed on the side where the distance is larger. Thus, the wide non-arrangement region 5 </ b> R can be formed on one side of the absorber 13 by making the arrangement position of the absorber 13 unevenly distributed in the width direction of the bag body 10 b.

  In addition, when a wearer wears urine collection pad 100b, it is preferred to wear so that wide non-arrangement field 5R may approach the wearer side. By wearing in this way, the tip of the male genitalia P can be easily placed in the non-arrangement region 5R, and the excreted urine can easily flow toward the bottom 10B. In this manner, by arranging the arrangement position of the absorber 13 unevenly, the non-arrangement region 5 </ b> R serving as a urine passage can be formed without providing the widened portion 18.

<4. Modification>
Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.

  For example, as shown in FIG. 8, the substantially rectangular bag body 10b shown in FIG. 6 is joined at one side in the width direction of the opening 10P with a seal joining region 41 inclined with respect to the longitudinal direction. A bag body in which the inner diameter of the bag body 10b gradually increases from the opening 10P toward the inside can be formed.

  Further, the absorbent body 13 may not be interposed between the top sheet 11 and the back sheet 12 in the vicinity of the bottom portion 10B of the bag body 10. If it does in this way, the thickness of the bottom part vicinity of bag 10 can be made small.

  Moreover, in said embodiment, although the laminated body 3 was bent and the bag 10 was formed by joining the side part, it is the same as the upper half (or lower half) of the laminated body 3, for example You may form a bag body by overlapping two laminated bodies of shape and joining both sides and the bottom side.

  Moreover, each element shown in each embodiment and modification can be combined with each other as long as no contradiction occurs.
