Since the stick-on type urine collecting pad is used by sticking it on the inside of the front opening of the underwear, it is difficult to open the front opening, which is inconvenient when taking out the male genitalia when urinating in a normal toilet. In addition, with the existing urine collecting pad, a part of the male genitalia in the underwear may protrude from the urine collecting pad, and the underwear may not be able to absorb urine when residual urine or urine leaks, and the underwear may get wet.

Therefore, it is an object of the present invention to provide a water-absorbent article in which a male genitalia fits well, and to eliminate an unpleasant feeling at the time of residual urine or urine leakage. At the same time, it aims to provide water-absorbent articles that can be used by women.

It should be noted that the water absorption of the water-absorbent article in the present invention is sufficient as long as it can absorb about 1 cc to 20 cc of urine, and it is not necessary to have enough water absorption to absorb a large amount of urine as required for nursing pants. ..

In order to solve the above problems, the water-absorbent article according to one aspect of the present invention is a water-absorbent article for underwear (underwear) worn on the lower body, and is a substantially rectangular shape having a front surface and a back surface. It is characterized by having a water absorbing portion, a ring-shaped string having elasticity provided on both short sides of the water absorbing portion, and a plurality of holders that are laterally movable and removable. The front surface (skin side) is water-absorbent, and the back surface (underwear side) is water-repellent or waterproof.

By using elastic ring-shaped strings provided on both short sides of the water-absorbent article and multiple movable and removable holders, the waist rubber part of the underwear (underwear) can be placed at an appropriate position. A water-absorbent article can be attached.

Further, in the method of attaching the water-absorbent article according to one aspect of the present invention, the water-absorbent portion is attached to the underwear worn on the lower body by using an elastic string and a plurality of laterally movable and removable holders. It is characterized by that. By making the holder movable in the lateral direction, the width between the pair of holders can be adjusted appropriately, and by pulling the elastic string appropriately, the water absorption part can be hung like a hammock. can. As a result, the male genitalia can be fitted well. Since the water absorption part is not attached to the underwear, it is easy to take it out from the front opening of the underwear. It can also be used for women by adjusting the length of the string, such as turning it upside down.

As the elastic string, for example, a rubber or resin string can be used. As the holder, a clip made of a soft resin such as polypropylene (PP) or polyethylene (PE) can be used. By using a soft resin as the holder, it can be made into a shape that can be moved laterally and can be removed, and it does not feel uncomfortable to the skin.

Further, the water absorbing portion may have a disposable urine absorbing pad placed on the upper surface of the elastic fabric. Even if it is just placed, the urine absorbing pad will be wrapped in the elastic fabric as a base in the used state, so there is no concern that it will come off. Of the water-absorbing parts, only the urine absorbing pad placed on the cloth is disposable, and the cloth as the base of the water-absorbing part can be reused, so that the cost can be suppressed.

Since the above configuration is adopted, according to the present invention, it is possible to provide a water-absorbent article in which the male genitalia fits well, and it is possible to eliminate an unpleasant feeling at the time of residual urine or urine leakage.

Further, according to the present invention, since the water absorbing portion is not attached and the elastic string and the holder that can move laterally are attached to the underwear for the lower body, the elastic string is appropriately pulled. Then, the water absorption part can be hung like a hammock, and the male genitalia can be taken out from the front opening part without resistance and can urinate normally. It can also be used for women by adjusting the length of the string, such as turning it upside down.

(First Embodiment)
1 to 7B are views for explaining a water-absorbent article according to the first embodiment of the present invention and a method for attaching the same. FIG. 1 is a schematic perspective view of the water-absorbent article 1 as viewed from diagonally above so that the method of attaching the underwear (underwear) to the waist rubber W can be understood. FIG. 2 is a view seen from directly above with the water-absorbent article 1 attached to the underwear (indicated by a broken line), and the left side of the drawing is the front side of the underwear.

As shown in FIGS. 1 and 2, the water-absorbent article 1 has a water-absorbent portion 2, elastic strings 3, 4, and holders 5, 6, 7, and 8. The water absorbing portion 2 is substantially rectangular and has a front surface (front surface) surface and a back surface surface. The front surface (skin side surface) has water absorption, and the back surface (underwear side surface) has water repellency or waterproof property. A string 3 having elasticity is attached to one short side of the water absorbing portion 2 so as to form a ring by combining the short side of the water absorbing portion 2 and the string 3. A pair of holders 5 and 6 are attached to the string 3 so as to sandwich the string 3. Similarly, a stretchable string 4 is attached to the other short side of the water absorbing portion 2, and a pair of holders 7 and 8 are attached to the string 4.

The surface (the surface on the skin side) of the water absorbing portion 2 is a water absorbing surface having water absorption, and depending on the capacity capable of absorbing water, for example, S (1 to 5 cc), M (5 to 10 cc), L (10 to 15 cc), etc. You can prepare 3 types of water and use them properly. The back surface (the surface on the underwear side) of the water absorbing portion 2 is a surface having water repellency or waterproofness, and can prevent the absorbed urine from leaking to the underwear side.

As long as the string 3 and the string 4 have elasticity, the material and the cross-sectional shape are not particularly limited, but for example, a rubber string or the like often used for a mask can be used. It is preferable that the skin does not feel uncomfortable even if it touches the skin. As a method of attaching the string 3 and the string 4 to the water absorbing portion 2, it can be fixed to the end by crimping like a string of a non-woven mask, or in a cloth sewn in a bag shape like a string of a cloth mask. You may attach it through a string. The strings 3 and 4 may be in a ring shape together with the short side of the water absorbing portion 2.

As shown in the figure, the holders 5, 6, 7, and 8 are configured to be laterally movable and removable, and can be held by being sandwiched between the elastic string and the waist rubber portion W of the underwear. Just do it. The holders 5, 6, 7, and 8 are clips having a shape as shown in FIG. 5, for example, commercially available clips made of a soft resin such as polypropylene (PP) or polyethylene (PE). Can be used.

Next, a method of attaching the water-absorbent article 1 to the underwear will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the water-absorbing portion 2 has a water-absorbing surface on the skin side and a water-repellent surface on the underwear side. Attach it so that it is sandwiched between the front sides of W. On the back side of the waist rubber portion W of the underwear, the string 4 is extended and attached so as to be sandwiched between a pair of holders 7 and 8. In the case of men, the front side is easier to get wet, so the string 4 attached to the back side should be longer than the string 3 attached to the front side. Even for women, adjust the length of the string as appropriate.

3 and 4 are enlarged views of the front side of the underwear of the attachment portion of the water-absorbent article 1. FIG. 3 is a diagram showing a state in which the distance between the pair of holders 5 and 6 is widened, and FIG. 4 is a diagram showing a state in which the distance between the pair of holders 5 and 6 is narrower than in the case of FIG. .. In FIGS. 3 and 4, the two corrugated lines indicate that a part of the water absorbing portion 2 is omitted. FIG. 5 is an enlarged view of the holder alone. FIG. 6A is a schematic view of the water-absorbent article 1 viewed from above with the distance between the pair of holders 5 and 6 and the pair of holders 7 and 8 widened, respectively, and FIG. 6B is a schematic view of FIG. 6A. It is sectional drawing of AB of. FIG. 7A is a schematic view of the water-absorbent article 1 viewed from above with the distance between the pair of holders 5 and 6 and the pair of holders 7 and 8 narrowed, and FIG. 7B is a schematic view of FIG. 7A. It is a cross-sectional view of CD of.

As shown in these drawings, the holders 5, 6, 7, and 8 are configured to be laterally movable and removable. As shown in FIGS. 4 and 7A, by narrowing the distance between the holders 5 and 6 and the holders 7 and 8, as shown in the CD cross-sectional view of FIG. 7B, the water absorbing portion 2 is not only in the front-rear direction but also in the front-rear direction. It also bends round in the horizontal direction. In this way, since the water absorbing portion 2 bends in a round shape in the lateral direction, the male genitalia fit better than the flat one. That is, since the entire water absorbing portion 2 is a rectangle whose width is not so wide and is attached by the elastic strings 3 and 4 and the holders 5 to 8, the entire water absorbing article 1 becomes like a hammock. The fit of the male genitalia is improved. It is also easy to take out from the front opening of trousers and underwear during urination.

When the prototype of the water-absorbent article 1 produced as described above was attached to commercially available men's underwear and worn by a plurality of users, the above-mentioned problems were solved and the effect of the present invention was confirmed. .. When I actually had him add some urine, it wasn't particularly difficult to take it out, and I was able to urinate normally. It was confirmed that there was no particular discomfort even when used by women.

(Second embodiment)
Next, the second embodiment will be described with reference to FIGS. 8A, 8B, 8C, 9A, 9B, and 9C. FIG. 8A is a schematic view of the water-absorbent article 10, which is another embodiment of the present invention, viewed from above with the distance between the pair of holders 4 and 5 and the holders 6 and 7 widened. .. 8B is a sectional view taken along the line EF of FIG. 8A, and FIG. 8C is a sectional view taken along the line GH of FIG. 8A. FIG. 9A is a schematic view of the water-absorbent article shown in FIG. 8A as viewed from above with the distance between the pair of holders 4 and 5 and the holders 6 and 7 narrowed. 9B is a sectional view taken along the line EF of FIG. 9A, and FIG. 9C is a sectional view taken along the line GH of FIG. 9A.

As shown in FIGS. 8A to 9C, in the second embodiment, the water absorbing portion 2 is provided with a rectangular disposable urine absorbing pad 21 slightly smaller than the base 22 on the upper surface of the base 22. As the base 22, it is preferable to use a soft and elastic fabric and have a water-repellent or waterproof back surface (underwear side surface). The urine collecting pad 21 is a water retention pad for urine, and S (1 to 5 cc), M (5 to 10 cc), and L (10 to 15 cc) are used properly depending on the amount of urine. As shown in FIGS. 9A to 9C when the water-absorbent article 10 is attached to the underwear by narrowing the distance between the pair of holders 4, 5 and 6, 7 and extending the elastic strings 3 and 4. The base 21 which is a soft and elastic fabric bends round in the front-back direction (GH direction) and the lateral direction (EF direction), and the inner urine absorbing pad 21 is surrounded and fixed by the base 22. It will not come off. Since only the urine collecting pad 21 is disposable and the other parts can be reused, there is little waste and the cost can be reduced. Since the second embodiment is the same as the first embodiment except that the configuration of the water absorbing portion is different, other descriptions will be omitted.

The above configuration is an example, and the present invention is not limited to the above configuration. It can be freely configured without departing from the spirit of the present invention. For example, as a holding portion for holding the elastic string, a button sewn on the underwear or the like may be used.
