Description

  The present invention relates to an absorbent article that receives excrement from a wearer.

  In a disposable diaper, since it is necessary to replace the entire diaper even when urinating a small amount, an economic burden is increased for the user. Therefore, conventionally, the wearer's excretory part is covered with an inexpensive auxiliary absorbent device (a so-called urine collecting pad or the like) inside the disposable diaper, and only the auxiliary absorbent device is replaced when urinating a small amount.

  As one of such auxiliary absorbent tools, a sheet-like absorbent pad that is attached to the inside of a disposable diaper is used. When the absorbent pad is attached, the absorbent pad is placed on the surface of the wearer side of the disposable diaper. Fastening a fastening part such as a hook-and-loop fastener or an adhesive tape provided on the back sheet is performed. For example, in Patent Document 1, by providing a locking fastener or the like in the longitudinal end region of the absorbent article, the absorbent article is drowned when a disposable diaper to which the absorbent article is attached is worn. A technique for suppressing this is disclosed.

Moreover, as another type of auxiliary absorbent, a male urine absorbent article that is attached to the wearer's penis inside a disposable diaper or underwear is also used. For example, in Patent Document 2, in a bag-shaped absorbent pad for men formed by adhering both side edges of a flat absorbent article folded in two, a penis is inserted into the bag on one side of the fold. A cross-shaped slit portion is formed.

As shown to A, in the edge part 26 of the longitudinal direction of the main-body part 2, the edge part 24 is return | folded by the back seat | sheet 23 side, and is fixed to the two corner | angular surface fasteners 41. FIG. In the absorbent article 1, in this state (that is, in a state where the edge portion 24 is folded back), a part of the two corner surface fasteners 41 does not overlap with the edge portion 24, and the edge portion 24 is formed on the backsheet 23. Is exposed from.

  Next, FIG. As shown to B, in the edge part 26 of the main-body part 2, one corner | angular part 25 (namely, corner part 25 of the right side in FIG. 3.B) is return | folded to the top sheet | seat 21 side, One corner 25 (that is, the left corner 25 in FIG. 3.B) is folded back to the top sheet 21 side. And the corner | angular surface fastener 41 of the corner | angular part 25 turned back previously is fastened by the top sheet 21 of the corner | angular part 25 turned back after that, and the two corner | angular parts 25 are fastened mutually and a penis is attached. A cylindrical portion 200 is formed to wrap the container. In a state where the absorbent article 1 is attached to the wearer, the free end 201 of the tubular portion 200 is located near the root of the wearer's penis.

  Here, in order to form the cylindrical portion 200, at least a part of the corner surface fastener 41 in the corner portion 25 of the main body portion 2 is an edge when the edge portion 24 is folded back to the backsheet 23 side. It is necessary to expose from the part 24 (that is, it does not overlap with the edge part 24). From the viewpoint of exposing the corner surface fastener 41 from the edge portion 24, the length in the longitudinal direction of the edge portion 24 at the side edge portion (that is, the end portion in the width direction) of the corner portion 25 is 40 mm or less. Is preferred. On the other hand, the top sheet 21 and the back sheet 23 are easily joined in the manufacture of the absorbent article 1 and the joining of the top sheet 21 and the back sheet 23 is maintained even when the absorbent core 22 absorbs water and expands. From the viewpoint, it is preferable that the length of the edge portion 24 in the longitudinal direction is 10 mm or more.

  Next, FIG. As shown in C, the main body 2 is folded in two with the back sheet 23 facing outward, and the other side portion 202 of the main body 2 (that is, the sheet on the side opposite to the side on which the cylindrical portion 200 is formed) 3), hereinafter referred to as “sheet portion 202”). As shown in FIG. At this time, the main body 2 is folded in half so that the length in the longitudinal direction of the sheet portion 202 is longer than the length in the longitudinal direction of the tubular portion 200. In the absorbent article 1, FIG. The corner surface fastener 41 (that is, the corner surface fastener 41 that does not contribute to the formation of the tubular portion 200) located outside the tubular portion 200 shown in C is stopped on the top sheet 21 of the seat portion 202. By being attached, the cylindrical part 200 is fixed to the sheet part 202.

  Then, FIG. The corner surface fastener 41 provided on the back sheet 23 of the sheet portion 202 shown in D is fixed to the inside of an exterior article such as a disposable diaper, whereby the absorbent article 1 is fixed to the disposable diaper or the like. Is done.

  As described above, the absorbent article 1 can be used as an absorbent pad that receives excrement from the wearer inside the exterior article, and is also attached to the wearer's penis to absorb urine. It can also be used as a urine absorbent article. Thus, since the absorbent article 1 can be used for any purpose of an absorbent pad and a male urine absorbent article, an appropriate type of absorption can be achieved when worn on a wearer in a hospital or a nursing facility. It is possible to reduce the labor for sorting out the sex goods. Moreover, the kind of absorbent article to be used can be reduced, and the labor required for management of the absorbent article can be reduced.

  When the absorbent article 1 is used as an absorbent pad, the absorbent article 1 is fastened to the inside of an exterior article such as a disposable diaper by the corner surface fastener 41, so that the absorbent article 1 is displaced or wrinkled. This can be prevented and leakage of excrement such as urine from the absorbent article 1 can be prevented. Further, by providing the side wall portions 3 on both sides in the width direction on the top sheet 21 side of the main body portion 2, it is possible to reliably prevent excrement from leaking from the side of the absorbent article 1.

As shown in FIG. 9, in the absorbent article 1 c, the corner surface fastener 41 is provided only at one corner 25 at the end 26 in the longitudinal direction of the main body 2, and is approximately the center in the width direction. A surface fastener 43 b is provided closer to the center in the longitudinal direction than the end portion 26. When the absorbent article 1c is used as an absorbent pad, the absorbent article 1c is firmly fixed to the exterior article by the corner surface fastener 41 and the surface fastener 43b. Moreover, when the absorbent article 1c is used as a male urine absorbent article, the cylindrical portion 200 (see FIG. 3.B) is formed by the corner surface fastener 41.

  In the absorbent article according to the first to third embodiments, the shapes of the hook-and-loop fasteners provided at the ends on both sides in the longitudinal direction may be different from each other.

In this case, the edge portion folded back toward the back sheet 23 only covers the corner surface fastener 41 and the like, and is not fixed by the corner surface fastener 41 and the like. In addition, from a viewpoint of wearer's comfort, it is preferable that the plastic film utilized as the back sheet 23 has moisture permeability (that is, air permeability).

  In the absorbent article, for example, an adhesive tape may be used instead of the hook-and-loop fastener as the corner fastening portion and the central fastening portion. In this case, even if the back sheet 23 is formed of only a plastic film, the edge portion folded back to the back sheet 23 side can be fixed on the back sheet 23 with an adhesive tape.

  In the case of absorbent articles, when the length of the edge part in the longitudinal direction is short or the edge part is made of a very soft material, when there is almost no discomfort due to the contact of the edge part with the skin When the absorbent article is used as a male urine absorbent, the folding of the edge portion may be omitted.
