Description

TECHNICAL FIELD The present disclosure relates to an absorbent article for men that is excellent in suppressing slippage of male genitalia.

Absorbent articles are commercially available in products for light incontinence and products for moderate to heavy incontinence. These products are appropriately selected according to the condition of the wearer and used at home, nursing homes, hospitals, and the like.

However, urinary leakage, which is peculiar to men, is a problem at nursing care sites for elderly men. For example, since the male genitalia of elderly men are shrinking due to aging, a gap may occur between the outerwear and the body when the outerwear such as pants or taped outerwear is worn directly on the body. In this case, the male genitalia protrudes outside the outer through the gap between the outer and the body, and the outer cannot absorb urine discharged from the male genitalia, or the male genitalia is held inside the outer. Urine discharged from the outer may leak to the outside of the outer through the gap between the outer and the body.

In order to solve this problem, conventionally, an inner layer is used inside the outer layer. For example, Patent Literature 1 discloses a method of wrapping the pubic area (male genitalia) with an inner pad such as a urine absorption pad inside an outerwear.

However, since the inner pad is thick, a new gap is created between the inner pad and the paper diaper, which is the outer, due to this thickness, and urine that has leaked from the inner layer leaks out through this gap. . As a countermeasure, an inner pad may be added to fill the gap, but it is not efficient because it consumes more pad than necessary.

On the other hand, as another solution to these problems of urine leakage, a method using a cylindrical product has been disclosed. For example, Patent Literature 2 discloses a disposable diaper for men, which is folded in two in the longitudinal direction with the central portion in the longitudinal direction of the absorbent body as a folding portion, and the side flaps in contact with each other are fixed to form a bag-like disposable diaper. disclosed. It has been shown that this makes it possible to assemble the diaper without mistakes when wearing it, and that urine leakage is less likely to occur.

However, in Patent Document 2, there is a problem that the male genitalia easily slides on the flat absorbent main body in the cylinder and tends to be displaced. This instability in maintaining the position induces the male genitalia to slip out of the tube, resulting in urine leakage when worn.

As described above, cylindrical male absorbent articles have a problem of urine leakage due to misalignment of the male genitalia, and there has been a demand for a solution to this problem.

The absorbent body 33 has an absorbent body concave portion (recessed portion) 34 extending in the longitudinal direction in a concave state from the skin side to the non-skin side. The absorbent body recessed portion 34 is arranged in the central portion of the absorbent body 33 in the width direction. In this embodiment, the absorbent body recessed portion 34 is formed in the shape of a bottomed groove having a U-shaped cross section recessed from the skin side to the non-skin side and extends in the longitudinal direction. Further, in the present embodiment, the non-skin side surface of the absorbent body 33 is formed in a substantially planar shape. That is, in the present embodiment, the thickness of the absorbent body recess 34 of the absorbent body 33 is thinner than the thickness of the other regions of the absorbent body 33 . The absorbent body recessed portion 34 extends continuously through the bottom portion 12 between the front region 30 a and the rear region 30 b of the absorbent body 30 . That is, the other sides in the longitudinal direction of the absorbent body recessed portions 34 of both the front region 30a and the rear region 30b of the absorbent body 30 extend to the bottom portion 12 of the male absorbent article 10 and are continuous with each other at the bottom portion 12. there is The one longitudinal end 36 of the absorbent recessed portion 34 of both the front region 30a and the rear region 30b of the absorbent main body 30 is located on the side of the opening 11 of the front region 30a and the rear region 30b of the absorbent main body 30. It is located on the bottom 12 side (the other side in the longitudinal direction) of the end 35 . That is, the absorbent body recessed portion 34 extends to the bottom portion 12 from a position spaced apart from the opening 11 of the male absorbent article 10 toward the other side in the longitudinal direction. A region 37 in which no recess is provided exists on one side of the absorber 33 in the longitudinal direction of the absorber recess 34 . The depth (the length in the thickness direction) L1 of the absorbent recess 34 is preferably set to a depth equal to or greater than half the thickness L2 of the absorbent 33 . The position of the one end 36 in the longitudinal direction of the absorbent body recess 34, the depth L1 of the absorbent body recess 34, and the widthwise length L3 of the absorbent body recess 34 are appropriate values capable of holding the male genitalia 1. is set to The appropriate value for holding the male genitalia 1 may be derived through experiments, simulations, or the like. In this embodiment, the non-skin side surface of the absorbent body 33 is formed in a substantially planar shape, but the present invention is not limited to this.

Next, the men's absorbent article 10 in a worn state will be described with reference to the drawings. FIG. 6 is a longitudinal cross-sectional view of the men's absorbent article 10 in a worn state, as seen from the rear. FIG. 7 is a longitudinal cross-sectional view of the men's absorbent article 10 in a worn state, as seen from the side.

As shown in FIGS. 2 , 4 , 6 and 7 , in the worn state, the male genitalia 1 extends longitudinally within the insertion space 13 and a portion of the side surface of the male genitalia 1 is absorbed by the absorber 33 . It enters into the body concave portion 34 . A region 37 of the absorbent body 33 in which the recessed portion on one side of the absorbent body recessed portion 34 in the longitudinal direction is not provided is positioned closer to the base than the glans 1a of the male genitalia 1 . The other side of the absorbent body recess 34 of the absorbent body 33 extends further to the other side in the longitudinal direction than the male genitalia 1 .

In the male absorbent article 10 configured as described above, the absorbent main body 30 is arranged on at least one side (both sides in this embodiment) in a direction intersecting the longitudinal direction of the insertion space 13, and extends from the bottom portion 12. It extends in the longitudinal direction to the end on the opening 11 side. The absorbent body 33 of the absorbent main body 30 has an absorbent body recess 34 extending along the longitudinal direction in a recessed state from the skin side to the non-skin side. Therefore, when worn, part of the side surface of the male genitalia 1 enters the absorbent body recess 34 of the absorbent body 33 (see FIGS. 4 and 7), so that the male genitalia 1 is stabilized in the absorbent body recess 34. The male genitalia 1 can be held by the absorbent body concave portion 34 and movement of the male genitalia 1 in the width direction with respect to the absorbent main body 30 can be suppressed.

In addition, the top sheet 31 has a top sheet recessed portion 31a extending in the longitudinal direction in a recessed state from the skin side to the non-skin side. are arranged so that they overlap each other. Therefore, in the wearing state, the male genitalia 1 can be held not only by the absorbent body recessed portion 34 but also by the top sheet recessed portion 31a, thereby further suppressing movement of the male genitalia 1 in the width direction with respect to the absorbent main body 30. can do.

Thus, according to this embodiment, it is possible to prevent the male genitalia 1 from slipping with respect to the absorbent main body 30 when worn. As a result, it is possible to prevent leakage of urine due to misalignment of the male genitalia 1 with respect to the absorbent main body 30 .

In addition, a part of the side surface of the male genitalia 1 enters the absorbent body recess 34 of the absorbent body 33, and the male genitalia 1 can be accommodated in the absorbent body recess 34, so that the male genitalia 1 and the absorbent main body 30 It is possible to suppress the gap generated between and prevent leakage of urine.

In addition, since the male genitalia 1 can be held along the absorbent body recessed portion 34, the direction of urine discharge from the male genitalia 1 (the direction of the male genitalia 1) can be directed toward the bottom portion 12 of the absorbent article 10 for men. It can be held in a facing state. Therefore, the distance between the urine discharge portion of the male genitalia 1 and the bottom portion 12 of the male absorbent article 10 can be minimized, and urine is absorbed by the absorbent body 33 of the bottom portion 12 of the male absorbent article 10. becomes easier.

In addition, since the other side of the absorbent body recess 34 of the absorbent body 33 extends to the bottom 12 of the male absorbent article 10 , urine can be guided to the bottom 12 of the male absorbent article 10 by the absorbent body recess 34 . can. Therefore, urine can be absorbed not only by the absorbent body 33 in the vicinity of the urine discharge portion of the male genitalia 1, but also by the absorbent body 33 at the bottom part 12 of the male absorbent article 10. Urine can be efficiently absorbed by using the whole rather than the part.

In addition, since the other side of the absorbent body concave portion 34 of the absorbent body 33 extends to the bottom portion 12 of the male absorbent article 10, the absorbent body 33 in the vicinity of the urine discharge portion of the male genitalia 1 swells and the weir 38 is formed. Even if it is possible, the height (the length in the thickness direction) of the portion where the weir 38 is generated can be suppressed. 8A and 8B are explanatory diagrams of the generation of the weir 38, in which FIG. 8A shows the male absorbent article 10 according to the present embodiment and FIG. 8B shows the conventional male absorbent article. For example, as shown in FIG. 8(a), in the male absorbent article 10 according to the present embodiment, the male genitalia 1 is held along the absorbent body recess 34, and the absorbent body recess 34 is the male absorbent article. Since it extends to the bottom portion 12 of the article 10 , urine discharged from the urine discharge portion of the male genitalia 1 circulates inside the absorbent body concave portion 34 . Even if the absorbent body 33 in the absorbent body recessed part 34 is swollen by the urine discharged from the male genitalia 1 into the absorbent body recessed part 34 and a weir 38 is generated near the male genitalia 1 (see FIG. 8A), Unlike the case where a weir 38 occurs in the absorbent body 33 of a conventional male absorbent article in which the absorbent body 33 is not provided with a recess (see FIG. 8(b)), the height of the portion where the weir 38 occurs is suppressed. be able to. As a result, urine can be prevented from being dammed, and urine can be more easily moved to the other side in the longitudinal direction than the dam 38, so urine can be guided to the bottom portion 12 side of the male absorbent article 10. , the entire absorber 33 can be used to efficiently absorb urine.

Further, the absorbent body recess 34 of the absorbent body 33 extends to the bottom part 12 from a position spaced apart from the opening 11 of the absorbent article 10 for men toward the other side in the longitudinal direction. That is, a region 37 in which no recess is provided exists on the one side of the absorber recess 34 in the longitudinal direction of the absorber 33 . Therefore, by appropriately setting the position of the one end 36 in the longitudinal direction of the absorbent body recessed portion 34, the depth L1 of the absorbent body recessed portion 34, and the widthwise length L3 of the absorbent body recessed portion 34, the 7 and FIG. 8( a ), the region 37 of the absorbent body 33 where the recessed portion is not provided can be placed closer to the base than the glans 1 a of the male genitalia 1 when worn. Thereby, as described above, when the weir 38 of the absorber 33 is generated, the height of the absorber 33 at the portion where the weir 38 is generated can be suppressed.

In addition, since there is a region 37 in which no recessed portion is provided on the one side of the absorbent body recessed portion 34 in the longitudinal direction of the absorbent body 33, discharged urine hits the bottom portion 12 of the absorbent article 10 for men and stretches in the longitudinal direction. Even if it returns to the above one side of the direction, there is no portion that serves as a flow path for urine from the absorbent body concave portion 34 to the opening 11 side. Therefore, the absorbent body 33 in the region 37 where the concave portion is not provided can preferably absorb the urine returning from the bottom portion 12 side, and urine leakage from the opening 11 can be prevented.

In addition, since the region 37 of the absorbent body 33 in which the recessed portion is not provided can be placed closer to the base than the glans 1a of the male genitalia 1 in the wearing state, the bulge of the glans 1a of the male genitalia 1 can be absorbed. It can be fitted to the one longitudinal end 36 of the body recess 34 (the stepped portion between the region 37 where no recess is provided and the absorber recess 34) (see FIG. 7). Therefore, the glans 1a of the male genitalia 1 can suppress the movement of urine from the absorbent body recessed portion 34 side to the gap between the region 37 of the absorbent body 33 where the recessed portion is not provided and the male genitalia 1. Therefore, leakage of urine from the opening 11 can be prevented.

In addition, the absorbent body recess 34 of the absorbent body 33 extends along the longitudinal direction in a recessed state from the skin side to the non-skin side, and in the worn state, a part of the side surface of the male genitalia 1 is covered with the absorbent body of the absorbent body 33 . It can be in a state of entering the recess 34 (see FIGS. 4 and 7). The surface of the absorbent body 33 on the non-skin side is formed in a substantially flat shape, and the thickness of the absorbent body concave portion 34 of the absorbent body 33 is thinner than the thickness of the other regions of the absorbent body 33 . Therefore, in the wearing state, the swelling of the male absorbent article 10 inside the outer 2 (swelling in the front-rear direction) can be suppressed, so that the outer 2 is lifted by the swelling of the male absorbent article 10 (from the body). float) can be suppressed, and the occurrence of a gap between the outer 2 and the body can be suppressed. For example, since the floating of the paper diaper (outer 2) due to the swelling of the male absorbent article 10 can be suppressed within the height range of the three-dimensional gathers of the paper diaper, the generation of a gap between the paper diaper and the body can be suppressed. can. As a result, the outer 2 can be fitted to the wearer's body, so even if urine leaks from the male absorbent article 10, leakage of urine to the outside of the outer 2 can be prevented.

Moreover, the depth L1 of the absorbent body recess 34 is preferably set to a depth equal to or greater than half the thickness L2 of the absorbent body 33 . Thereby, the depth L1 of the absorbent body concave portion 34 can be set deep so that the male genitalia 1 can be preferably held. Also, in order to suppress the height of the portion where the weir 38 is generated, the depth L1 of the absorber concave portion 34 can be set deep.
