BACKGROUND OF THE INVENTION
The present invention relates to an absorbent pad for men used by bedridden men, incontinent persons, etc., in combination with used disposable diapers or through underwear. More specifically, the present invention relates to a male absorbent pad that has a high leakage prevention effect and is easy to wear.
[0002]
[Prior art]
A conventional male absorbent pad is a rectangular one comprising a liquid-permeable top sheet, a liquid-impermeable back sheet having the same shape as the top sheet, and an absorbent body disposed between the two sheets. It is. When using the male absorbent pad, the male absorbent pad is worn around the penis while the male absorbent pad is wrapped around the penis while rounding into a substantially conical shape around the corner of the rectangular male absorbent pad. The outer periphery of the was fixed with tape or the like.
[0003]
However, since this type of male absorbent pad is used by directly mounting the male absorbent pad around the penis, there is a problem that the wearer feels uncomfortable or tightened and is difficult to use. On the other hand, if the wearer wraps weakly so as not to cause a sense of incongruity or tightness, the male absorbent pad is easily detached from the penis, causing a problem of urine leakage.
[0004]
Then, the male absorption pad as shown to FIG. 7 (A) and (B) is disclosed (for example, patent document 1). That is, a liquid-permeable top sheet 1, a liquid-impermeable back sheet 2, an absorber 3 disposed between these two sheets, and a liquid-impermeable gather sheet 7 above the top sheet 1 And a genital holding space 4 is formed between the top sheet 1 and the gather sheet 7. The gather sheet 7 has an opening 5, and an elastic member 6 is arranged around the opening 5.
[0005]
Then, the male genitalia is inserted through the opening 5 of the male absorption pad and held in the genital holding space 4, and the excrement is absorbed by the absorber 3 through the top sheet 1. As a result, the male absorbent pad is not directly wrapped around the penis and worn, and the wearer is alleviated from feeling uncomfortable.

[0043]
The top sheet 11 and the gather sheets 14A and 14B have a water-soluble glue such as hot melt, starch-based or CMC (carboxymethyl cellulose), a highly fluid adhesive, heat, ultrasonic waves, etc. Joined by welding.
[0044]
When using the male absorbent pad P configured as described above, for example, as shown in FIG. 3 (A), the opening of the male absorbent pad P with the male genital B facing downward with the wearer lying on his back 15, the male genital B is placed on the upper side of the auxiliary sheet 17 and held in the genital holding space 18.
[0045]
Then, the male genital B is firmly held by the male absorbent pad P by the auxiliary sheet 17 including the elastic member 16 and the gather sheet 14A including the elastic member 16.
[0046]
At this time, because the male genital B is placed on the upper side of the auxiliary sheet 17, even when the wearer excretes urine in a supine state, the liquid-permeable auxiliary sheet 17 weakens the momentum while allowing the urine to penetrate. Since the urine is firmly received by the gather sheet 14B including the two elastic members 16 outside the auxiliary sheet 17 while being diffused throughout the auxiliary sheet 17, the urine does not leak from the opening 15.
[0047]
By the way, the male genital B may be faced upward and inserted through the opening 15 of the male absorption pad P, and held in the genital holding space 18 so that the penis rests on the upper side of the auxiliary sheet 17. In this case, as shown in FIG. 3 (B), the male absorbent pad P is used by changing the orientation by 180 ° from FIG. 3 (A). In other words, the male genital B is faced upward and the male genital B is placed on the upper side of the auxiliary sheet 17 and held in the genital holding space 18 with the male genital B facing upward and inserted through the opening 15 of the male absorption pad P. 3A, the auxiliary sheet 17 provided with the elastic member 16 and the gather sheets 14A and 14B firmly wrap the male genital B.
[0048]
In this case, since the male genital B is placed on the upper side of the auxiliary sheet 17, even if the wearer excretes urine in a supine state, the liquid-permeable auxiliary sheet 17 weakens the momentum while allowing the urine to penetrate and assists. Since it is diffused throughout the sheet 17, urine does not leak from the opening 15.
[0049]
Thereafter, as shown in FIG. 4, after placing the buttocks of the wearer on the top sheet 22 of the back body 24 of the unfoldable disposable diaper 21, the front body 23 is folded and the male absorbent pad P is attached as shown in FIG. The unfoldable disposable diaper 21 is mounted by fixing a fastening member 25 such as a double-sided tape or a mechanical fastener on the back sheet of the front body 23 of the unfoldable disposable diaper 21 by placing it on the wearer's abdomen.
[0050]
Since the male absorption pad P of this example is configured as described above, even when the wearer lies on his back and excretes urine, the auxiliary sheet 17 weakens the momentum of the urine and diffuses the urine quickly. Therefore, urine does not leak from the opening 15. Therefore, according to the male absorbent pad P of this example, liquid excrement such as urine can be prevented from leaking outside from the opening 15 regardless of the direction of the male genital B.
[0051]
Moreover, since the male genitalia B can be held in a free state, the uncomfortable feeling given to the wearer can be reduced. In addition, since the male absorbent pad P of the present invention holds the male genital B in the genital holding space 18, it can follow the movement of the wearer.
[0052]
Further, in the above-described example, preferably, when folded in half at the center in the length L direction and packaged, there is an advantage that it is easy to determine the center when attached to a developed paper diaper or the like, and the center of the absorbent pad Is easily applied to male genital B. In addition, it becomes easy to guide the liquid excrement toward the center of the absorbent body through the valley formed by the folding marks of the absorbent pad folded in half.
[0053]
In the above-described example, the auxiliary sheet 17 is provided integrally with the top sheet 11. However, the present invention is not limited to this, and the auxiliary sheet 17 and the top sheet 11 are provided as shown in FIG. It may be provided separately.
[0054]
Moreover, in the above-mentioned example, although the example which mounted | wearing with the deployment type | mold paper diaper was demonstrated to the wearer who mounted | wearing with the absorption pad P for men, this invention is not limited to this, The absorption pad P for men is a pants type. You may use it with a paper diaper or underpants type underwear. Accordingly, if the back sheet 12 of the male absorbent pad P is provided with an adhesive double-sided tape or a male material of a mechanical fastener, it is possible to prevent the male absorbent pad P from being displaced due to the movement of the wearer. Is preferred.
[0055]
Furthermore, in the above-described example, the back sheet 12 is liquid-impermeable, but the present invention is not limited to this, and the back sheet 12 may be liquid-permeable.
[0056]
In the above example, the male absorbent pad P is formed in a rectangular shape, but the present invention is not limited to this, and the corners C1 to C4 are equally cut as shown in FIG. It is good also as a rectangle which lacked, and as shown to FIG. 6 (B), two corner | angular parts C3 and C4 in the both ends of one long side are made into two corner | angular parts C1 and C2 in the other long side. As compared with the above, it may be cut out largely, or only the corners C3 and C4 may be cut out. In this way, when the male absorbent pad P is worn, the notched portion can improve the fit of the crotch. Of course, the same effect can be obtained if not only the corners of the top sheet 11 and the back sheet 12 are cut out but only the corners of the rectangular absorber 13 are cut out.
[0057]
