Then, the free ends 12 a and 13 a of the side sheets 12 and 13 are erected so as to be separated from the top sheet 11 by the contraction force of the elastic members 14 to 17. This effectively prevents the wearer's urine from leaking from the left and right edges of the male urine absorbent article 1 at the crotch or the like.

  For the side sheets 12 and 13, for example, a liquid-impermeable sheet material is used. As the sheet material, for example, a water-repellent nonwoven material (spunbond nonwoven fabric, melt blown nonwoven fabric, SMS nonwoven fabric, etc.) is used. The elastic members 14 to 17 are made of an elastic stretch material (polyurethane yarn, polyurethane film, natural rubber, etc.) generally used for disposable diapers.

  The exterior material 3 is formed using a water-repellent sheet material or a liquid-impermeable sheet material in order to prevent urine absorbed by the absorbing member 4 and the like from seeping out. For example, a water-repellent nonwoven fabric material (spunbond nonwoven fabric, melt blown nonwoven fabric, SMS nonwoven fabric, etc.) or plastic film (breathable or non-breathable) that is usually used for disposable diapers, Is preferably a breathable plastic film) or a laminate of them. In this embodiment, the exterior material 3 is comprised with the breathable plastic film and the nonwoven fabric (for example, water-repellent nonwoven fabric) bonded together on the outer surface side of the breathable plastic film.

  The absorbent member 4 includes a plurality of elongated absorbent cores 21 and 22 arranged along the longitudinal direction Y with a gap in the width direction X. In the present embodiment, a pair of left and right absorbent cores 21 and 22 are used. Each of the absorbent cores 21 and 22 has a lump formed by mixing a granular polymer absorber in a hydrophilic fiber aggregate layer made of pulverized pulp fiber, cellulose fiber, or a mixture thereof, and liquid permeability that wraps the lump.

  As shown in FIG. 4, the absorbent sheet 5 includes two liquid-permeable sheet materials 23 and 24 and a polymer absorber 25 sandwiched between the two liquid-permeable sheet materials 23 and 24. And has a thin sheet-like form. Hot melt adhesives 26 and 27 for bonding are applied to the inner surfaces of the two sheet materials 23 and 24. Moreover, in the some joining part 28 of the absorption sheet 5, joining by welding (heat welding or ultrasonic welding) is performed. In addition, as the liquid-permeable sheet materials 23 and 24, for example, tissue paper or liquid-permeable nonwoven fabric (such as an air-through nonwoven fabric or a spunlace nonwoven fabric) is used.

  Next, the configuration of the male urine absorbent article 1 to which the side joints 34 and 35, which are finished products, are joined will be described.

  The male urine absorbent article 1 includes a folding part 31, a short part 32, a long part 33, and side joint parts 34 and 35. The folding part 31 is provided at a position shifted to one side from the center in the longitudinal direction Y of the male urine absorbent article 1 and defines the folding position of the male urine absorbent article. The short part 32 consists of the part located in the one side of the longitudinal direction Y from the folding part 31 of the urine absorption article 1 for men, and is folded back as shown by the arrow B in the folding part 31 and arranged on the skin surface side of the wearer. Is done. The long portion 33 includes a portion located on the other side in the longitudinal direction Y from the folded portion 31 of the male urine absorbent article 1 and is disposed on the outer surface side with respect to the short portion 32.

  And the edge part of the both sides of the width direction X in the short part 32 and the long part 33 which were folded in half by the folding part 31, and the long part 33 is joined by welding (heating welding or ultrasonic welding). This joint is referred to as side joints 34 and 35.

  Thus, the wearer's penis is formed by the short portion 32 where the left and right edges are joined together by the side joint portions 34 and 35 and the portion (bag forming portion 33a) of the long portion 33 facing the short portion 32. A substantially bag-like bag portion 36 into which is inserted is formed.

  Moreover, the part (overhang | projection part 33b) which protrudes in the longitudinal direction Y from the bag part 36 in the elongate part 33 is passed by the wearer's crotch part from the front side to the back side at the time of wearing this urine absorbent article 1 for men. It has become so. For this reason, the overhang dimension in the longitudinal direction Y of the overhang portion 33b is set to a value sufficient to pass the overhang portion 33b through the wearer's crotch.

  Further, the edge portion 32 a opposite to the folding portion 31 in the longitudinal direction Y of the short portion 32 is continuous in a substantially straight line along the width direction X.

  Next, with reference to FIG.5 and FIG.6, the mounting method to the wearer of this male urine absorption article 1 is demonstrated. First, the opening 36a of the bag portion 36 of the male urine absorbent article 1 is opened, and the wearer's penis is inserted upward into the bag portion 36 as indicated by an arrow C in FIG. Subsequently, the protruding portion 33b of the long portion 33 is passed through the wearer's crotch from the front side to the rear side. Thereby, for example, the section Lc in the longitudinal direction Y of the overhang portion 33b is sandwiched between the left and right legs of the wearer. Subsequently, as shown in FIG. 6, a disposable diaper (or a pants-type disposable absorbent article) 41 is mounted on the male urine absorbent article 1.

  As described above, according to the present embodiment, the overhanging portion 33b projecting in the longitudinal direction Y from the bag portion 36 in the long portion 33 of the male urine absorbent article 1 is worn when the male urine absorbent article 1 is worn. The wearer's crotch is passed from the front side to the rear side and is sandwiched between the crotch part. For this reason, it is possible to effectively prevent the displacement of the male urine absorbent article 1 in the worn state and the detachment of the penis inserted into the bag portion 36.

  Moreover, since the edge part of the both sides of the width direction X of the male urine absorption article 1 is joined beforehand by the side junction parts 34 and 35 and the bag part 36 is formed, it is the both sides of the male urine absorption article 1 at the time of wear. It is not necessary to perform edge joining work and can be easily and quickly mounted.

Further, since the penis of the wearer are inserted into the bag portion 36 of the male urine absorbent product 1, (when it is for example, lying in-out upward or YokoMuko) when the wearer is lying, It is possible to effectively prevent urine from leaking from the ventral side.

  In addition, at least a section La (projecting section 33b) of the long section 33 and the short section 32 extending in the longitudinal direction Y from the bag section 36 in at least the long section 33 of all sections L along the longitudinal direction Y. A solid side gather is provided in part (substantially the entire length of the overhang portion 33b in this embodiment) by the side sheets 12, 13 and the elastic members 14-17. For this reason, it is possible to effectively prevent the wearer's urine from leaking from the left and right edges of the male urine absorbent article 1 at the crotch and the like by this three-dimensional side gather. Furthermore, in this embodiment, since the three-dimensional side gathers are provided also in the bag forming part 33a of the short part 32 and the long part 33 which comprise the bag part 36, the higher function of preventing urine leakage is obtained.

  Moreover, since the edge part of the both sides of the width direction X in the short part 32 and the long part 33 of the urine absorbent article 1 for men is welded by the side joining parts 34 and 35 (heating welding or ultrasonic welding), The short part 32 and the long part 33 can be joined without a gap, and urine can be reliably prevented from seeping out from the bag part 36 via the side joint parts 34 and 35.

  Moreover, since the absorption member 4 is provided with a plurality of (for example, two) absorption cores 21 and 22 arranged at an interval in the width direction X, the absorption member 4 is interposed via the top sheet 11 of the male urine absorbent article 1. The introduced urine is absorbed by the respective absorption cores 21 and 22 from the skin surface side surface, and the urine is rapidly diffused in the longitudinal direction Y by the gap 20 between the absorption cores 21 and 22, and a wide range of absorption cores 21 and 22 can be used for quick absorption. As a result, it is possible to effectively prevent urine leakage by rapidly absorbing urine. Moreover, since the absorption cores 21 and 22 are arranged at intervals in the width direction X, even when the absorption cores 21 and 22 expand by absorbing urine, the absorption cores 21 and 22 adhere to each other and absorb. The diffusion of urine through the gap 20 between the cores 21 and 22 is not hindered.

  Moreover, since the absorbent member 4 is composed of a plurality of elongated absorbent cores 21 and 22 arranged along the longitudinal direction Y with an interval in the width direction X, the flexibility of the absorbent member 4 is improved. Thus, the male urine absorbent article 1 can be flexibly fitted between the wearer's crotch.

  In addition, since the absorbent sheet 5 including the polymer absorbent body 25 is disposed between the interior material 2 and the absorbent member 4, the urine diffusibility is improved and the urine absorption capacity can be increased.

  In addition, since the absorbent sheet 5 does not escape once it absorbs moisture, the urine once absorbed by the absorbent member 4 and the absorbent sheet 5 can be obtained by arranging the absorbent sheet 5 between the absorbent member 4 and the interior material 2. It can prevent returning to the skin surface side of the male urine absorbent article 1 through the interior material 2.

  Moreover, since the edge part 32a of the short part 32 which forms the opening part 36a of the bag part 36 is continued substantially linearly along the width direction X, when the male urine absorption article 1 is worn, the bag part 36 The wearer's penis is hard to come off.

  Moreover, since the exterior material 3 is comprised by bonding a plastic film and a nonwoven fabric, and the nonwoven fabric is arrange | positioned on the outer surface side, the touch of the male urine absorption article 1 becomes good.
