Description

The present invention relates to a male absorbent article particularly suitable for men's light incontinence, and more particularly to a male absorbent article that expands and contracts along underwear to facilitate fitting to a male genitalia.

Conventionally, an absorbent article for men that absorbs light urine leakage (about 5 to 15 cc) such as residual urine has been known. For example, in Patent Document 1 below, a crease extending in the first direction is folded back with the surface sheet inside, and the outer surface of the absorber has the crease at both ends in the first direction. Men's incontinence pads with cross-extending elastic members are disclosed.

Further, in Patent Document 2 below, a pair of barrier cuffs (three-dimensional cuffs) are formed to prevent lateral leakage of urine by separating them toward the wearer's body side by the contraction action of the cuff elastic element provided on the barrier cuff sheet. The men's absorbent pad has been disclosed.

Japanese Unexamined Patent Publication No. 2016-116722 Japanese Patent No. 5514359

According to Patent Document 1, in a state where the male incontinence pad is deployed, the length of the peripheral edge of the absorber is shortened by the contraction force of the elastic member, and it becomes easy to form the male incontinence pad in an outwardly bulging shape. Although it is described that the male incontinence pad can be appropriately applied to the male genitalia, the structure does not allow it to expand and contract according to the expansion and contraction of the underwear, so the penis and scrotum and shade are described. There was a problem that the pad did not follow even if the underwear was stretched due to the protruding part of the body such as the scrotum, and it was difficult to fit the male genitalia.

Further, in the absorption pad for men described in Patent Document 2, the male genitalia are housed in the space formed by the pair of barrier cuffs, but if a thick member such as a three-dimensional barrier cuff is present, a feeling of strangeness is felt when the male genitalia are attached. It was easy to feel. In addition, the elastic force of the three-dimensional barrier cuff may easily create a space between the male genitalia and the male absorbent pad body, and in that case, the adhesion with the male genitalia may decrease and leakage may occur. was there.

Therefore, a main object of the present invention is to provide an absorbent article for men, which improves the fit to a male genitalia, prevents leakage of body fluids, and reduces discomfort when worn.

In order to solve the above-mentioned problems, as the present invention according to claim 1, in an absorbent article for men provided with an absorber,
An elastic region that can be expanded and contracted in at least the width direction is formed on the outer side in the width direction from the absorbent body, and the non-skin side surface of the absorbent article for men on the outer side in the width direction from the elastic region is displaced to be fixed to the underwear. An absorbent article for men is provided, characterized in that it is provided with a retaining layer.

In the invention according to claim 1, an elastic region that can be expanded and contracted at least in the width direction is formed on the outer side in the width direction from the absorber, and a slip prevention layer for fixing to the underwear is formed on the outer side in the width direction from the elastic region. When the men's absorbent article is attached to the underwear, the elastic region expands as the underwear stretches due to the protruding penis or sac, and the men's absorbent article also expands. Therefore, the absorber can be maintained in close contact with the penis. For this reason, it is possible to prevent leakage of body fluids, and the absorber directly adheres to the penis due to the elastic force of the elastic region, so that a good wearing feeling that is the same as that of normal underwear can be obtained.

As the present invention according to claim 2, the men's absorbent article according to claim 1, wherein the stretchable region is formed over the entire circumference of the absorber is provided.

In the invention according to claim 2, by forming the elastic region around the entire circumference of the absorber, in addition to the elastic force on both sides of the absorber, the elastic force is also applied to the upper and lower parts of the absorber. Therefore, it becomes easier for the absorber to fit so as to wrap around the penis.

According to the third aspect of the present invention, the stretchable region is formed of a stretchable sheet in which the material itself has elasticity, or a plurality of stretchable regions are formed along the width direction and at intervals in a direction orthogonal to the width direction.

The men's absorbent article according to any one of claims 1 to 3, which is set to be larger than the stretching force of the region, is provided.

In the invention according to claim 4, when the elastic region is formed around the entire circumference of the absorber, the elastic force of the region overlapping the absorber in the width direction is applied in the width direction to the absorber. By setting it larger than the elastic force of the non-overlapping area, the part that overlaps with the absorber in the width direction contracts more, and the absorber can easily adhere to the male device and is absorbed by the skin side of the absorbent article for men. A pocket-like space is formed in which the body bulges to the non-skin side, and the bulging absorber easily fits into the protruding penis.

According to the fifth aspect of the present invention, the elastic region is formed by disposing a plurality of filamentous elastic elastic members between the upper layer sheet on the skin side and the lower layer sheet on the non-skin side, and the upper layer sheet is formed. And the lower layer sheet are composed of separate sheets, and the sheet on one side of the upper layer sheet and the lower layer sheet extends to the outside of the sheet on the other side so as to wrap both ends in the vertical direction of the sheet on the other side. The men's absorbent article according to any one of claims 1 to 4 is provided.

In the invention according to claim 5, when a plurality of filamentous elastic elastic members are arranged between the upper layer sheet and the lower layer sheet in the elastic region, and the upper layer sheet and the lower layer sheet are formed of separate sheets. Since one of the upper sheet and the lower sheet is extended to the outside of the other sheet by wrapping both ends of the other sheet in the vertical direction, the edges of the upper sheet and the lower sheet are used. The edge does not come into contact with the skin surface, and the side edge of the sheet on the other side is covered by the folded portion of the sheet on the other side. Therefore, the feeling of strangeness at the time of wearing can be reduced.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<Basic structure of absorbent article 1 for men>
As shown in FIGS. 1 and 2, the absorbent article 1 for men according to the present invention has a leak-proof sheet 2 made of a polyethylene sheet, a polypropylene sheet, or the like, and a liquid-permeable surface that rapidly permeates body fluid such as urine. Covers the outermost surface (non-skin side surface) of the sheet 3, the absorbent body 4 made of cotton-like pulp or synthetic pulp interposed between the two sheets 2 and 3, and the absorbent article 1 for men, and puts it in a predetermined area. It is composed of a stretchable sheet 5 to which stretchability is imparted. Further, around the absorber 4, the outer edge portion of the leak-proof sheet 2 and the liquid-permeable surface sheet 3 is bonded to the outer periphery by an adhesive such as hot melt or a bonding means such as a heat seal or an ultrasonic seal. A flap portion F is formed in which the leak-proof sheet 2 in which the absorber 4 does not exist and the liquid-permeable surface sheet 3 are bonded to each other. Although not shown, at least the skin side surface and the non-skin side surface of the absorber 4 may be covered with an encapsulating sheet made of crepe paper or a non-woven fabric in order to maintain the shape of the absorber 4 and improve the diffusivity. ..

Hereinafter, the structure of the absorbent article 1 for men will be described in more detail.
As the leak-proof sheet 2, a sheet material having at least water impermeability such as an olefin resin sheet such as polyethylene or polypropylene is used, but in addition to this, a laminated non-woven fabric in which a non-woven fabric is laminated on a polyethylene sheet or the like, or a waterproof film is used. A non-woven fabric sheet (in this case, the waterproof film and the non-woven fabric form a leak-proof sheet) can be used after interposing and ensuring substantially impermeable property. In recent years, from the viewpoint of preventing stuffiness, those having moisture permeability have tended to be used. This water-impervious / moisture-permeable sheet material is a microporous sheet obtained by melting and kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene to form a sheet, and then stretching it in a uniaxial or biaxial direction. Is.

Next, as the liquid-permeable surface sheet 3, a perforated or non-perforated non-woven fabric, a porous plastic sheet, or the like is preferably used. The material fibers constituting the non-woven fabric can be, for example, olefin-based fibers such as polyethylene or polypropylene, synthetic fibers such as polyester-based and polyamide-based, recycled fibers such as rayon and cupra, and natural fibers such as cotton. A non-woven fabric obtained by an appropriate processing method such as a lace method, a spunbond method, a thermal bond method, a melt blown method, or a needle punching method can be used. Among these processing methods, the spunlace method is excellent in that it is flexible and the spunbond method is excellent in drapeability, and the thermal bond method and the air-through method are excellent in that it is bulky and has high compression stability. The fibers of the non-woven fabric may be either long fibers or short fibers, but it is preferable to use short fibers in order to give the texture of the towel cloth. Further, in order to facilitate the embossing treatment, it is preferable to use an olefin fiber such as polyethylene or polypropylene having a relatively low melting point. Further, composite fibers such as core-sheath type fibers having a high melting point fiber as a core and a low melting point fiber as a sheath, side-by-side type fibers, and split type fibers can also be preferably used.

The absorber 4 interposed between the leak-proof sheet 2 and the liquid-permeable surface sheet 3 is, for example, one in which a highly water-absorbent resin is mixed in pulp, or one in which chemical fibers are mixed in pulp and high water absorption. Those mixed with sex resin are used. Although not shown, it is desirable that the absorber 4 be covered with an encapsulating sheet in order to maintain its shape, rapidly diffuse the body fluid, and prevent the once absorbed body fluid from regurgitating. Examples of the pulp include cellulose fibers such as chemical pulp and molten pulp obtained from wood, and artificial cellulose fibers such as rayon and acetate. It is preferably used in terms of price. Further, as the absorber 4, an air-laid absorber capable of reducing the bulk or a polymer sheet in which a highly water-absorbent resin is arranged between two layers of a non-woven fabric may be used. When the absorber 4 is made of the polymer sheet, and when the skin-side sheet of the polymer sheet forms the skin contact surface layer, the liquid-permeable surface sheet 3 may not be provided.

Further, synthetic fibers may be mixed with the absorber 4. As the synthetic fiber, for example, polyolefin-based fibers such as polyethylene or polypropylene, polyester-based fibers such as polyethylene terephthalate and polybutylene terephthalate, polyamide-based fibers such as nylon, and copolymers thereof can be used, and these two types can be used. It may be a mixture. Further, composite fibers such as core-sheath type fibers having a high melting point fiber as a core and a low melting point fiber as a sheath, side-by-side type fibers, and split type fibers can also be used. In the case of hydrophobic fibers, it is desirable to use the synthetic fibers surface-treated with a hydrophilic agent so as to have an affinity for body fluids.

Examples of the highly water-absorbent resin include a polyacrylic acid crosslinked product, a self-crosslinked polyacrylic acid salt, a saponified product of an acrylic acid ester-vinyl acetate copolymer crosslinked product, an isobutylene / maleic anhydride copolymer crosslinked product, and the like. Examples thereof include cross-linked polysulfonates and partially cross-linked water-swellable polymers such as polyethylene oxide and polyacrylamide. Of these, acrylic acid or acrylate-based ones having excellent water absorption amount and water absorption rate are preferable. In the manufacturing process, the highly water-absorbent resin having the water-absorbing performance can adjust the water-absorbing power and the water-absorbing rate by adjusting the cross-linking density and the cross-linking density gradient.

When the encapsulating sheet covering the absorber 4 is provided, as a result, the encapsulating sheet is interposed between the liquid-permeable surface sheet 3 and the absorber 4. When the encapsulated sheet is made of crepe paper, the encapsulated sheet having excellent absorbability rapidly diffuses urine and prevents the urine from regurgitating.

It is preferable that one or both of the absorber 4 and the encapsulating sheet has a color other than white, preferably a relatively dark color having a low lightness such as black or gray. Since the present invention relates to an absorbent article for men, the use of a relatively dark color gives a calm impression for men, makes it less noticeable when worn on dark-colored underwear, and makes the trace of urination less noticeable. Become. The coloring method is not particularly limited, and an appropriate dyeing method or coloring raw material can be used. Further, coloring may be applied by containing activated carbon in either or both of the absorber 4 and the encapsulating sheet. This makes it possible to add the deodorizing effect of activated carbon.

<Elastic area>
The elastic sheet 5 is formed in a plane shape that is at least larger in the width direction than the laminate in which the absorber 4 is interposed between the leak-proof sheet 2 and the liquid-permeable surface sheet 3, and is in the width direction from the laminate. The portion extending outward is an elastic region 6 that can be expanded and contracted at least in the width direction. This elastic region 6 stretches as the underwear stretches due to the male genitalia such as the protruding penis and scrotum when the absorbent article 1 for men is attached, and the absorber 4 maintains a state of being in close contact with the penis. It is provided for this purpose.

The stretchable region 6 is a region shaded in FIG. 1, and covers the entire circumference of the absorber 4 including the respective regions of both ends in the width direction and both ends in the vertical direction of the absorber 4. It is formed. That is, the elastic region 6 is formed so as to surround the periphery of the absorber 4, and the absorber 4 is arranged in an island shape in the central portion of the elastic region 6.

On the other hand, it is preferable not to impart elasticity to the portion overlapping the absorber 4 in the thickness direction. If elasticity is applied to the portion overlapping with the absorber 4, the absorber 4 may shrink and the fit to the penis may be deteriorated. In order not to impart elasticity to the portion overlapping with the absorber 4 in this way, either the elastic member is not arranged, or the elastic member is cut to deactivate the elasticity. It can be achieved by using a non-stretchable means that deactivates the stretchability by ultrasonically or thermocompression-bonding the stretchable member. The above-mentioned "not imparting elasticity" is a portion in which the expansion / contraction force is eliminated by applying the above-mentioned non-expansion / contraction means to the region overlapping with the absorber 4 in the thickness direction. This "eliminating the elastic force" means that the elastic force of the elastic region does not act at all by the non-expandable means, or only an extremely small elastic force acts as compared with the elastic region 6. It refers to the state of being in a state. Specifically, the elongation rate of the region not imparted elasticity is preferably 1/10 or less, particularly 1/20 or less, with respect to the elongation rate of the elasticity region 6.

As shown in FIG. 3, the stretchable region 6 may be provided only at both ends in the width direction of the absorber 4 and may not be provided at both ends in the vertical direction. That is, the absorber 4 may be arranged over substantially the entire length of the elastic sheet 5 in the vertical direction. The elongation of the underwear due to the protruding penis and scrotum can be sufficiently covered by the elastic forces of the elastic regions 6 and 6 provided at both ends in the width direction of the absorber 4, and the upper and lower sides of the absorber 4 in the form shown in FIG. Since the elastic regions 6 and 6 provided at both ends in the direction are additional configurations for more reliably fitting the both ends in the vertical direction of the absorber 4, the fit is significantly reduced even without these regions. There is nothing to do. By providing the elastic regions 6 only at both ends in the width direction of the absorber 4 in this way, the area of the absorber 4 can be increased, so that the absorption area of the body fluid can be increased, and the exterior sheet 5 and the elastic regions can be increased. Since the area of 6 can be reduced, the material cost can be reduced.

On the other hand, it is desirable that the peripheral edge portion of the stretchable sheet 5 does not impart elasticity over the entire circumference. Since the slip prevention layer 7 is arranged on the non-skin side surface at both ends in the width direction, it is preferable not to impart elasticity so that the slip prevention layer 7 can be easily fixed to the underwear. Further, both ends in the vertical direction should not be stretched for the purpose of making it easy to attach to the underwear and stabilizing the absorber 4 at the time of attachment. It is preferable to use the above-mentioned non-stretchable means in the region where the stretchability is not imparted.

Any of the following means can be used to form the stretchable region 6. In the first means, as shown in FIGS. 1 and 2, the stretchable region 6 is formed by the stretchable sheet 5 in which the material itself has elasticity. As the sheet material having elasticity of such a material itself, for example, an elastic film, a non-woven fabric, a urethane foam, or the like processed into a sheet shape can be used. The stretchable sheet 5 is preferably stretchable in the width direction of the men's absorbent article 1 while hardly stretching in the vertical direction, but stretches in both the width direction and the vertical direction. Anything that is free may be used.

As the elastic sheet 5, it is preferable to use a stretchable sheet 5 having an elongation rate of 20% to 40% according to the B method (constant load method of the woven fabric) of the stretchability of the stretchable fabric and the knitted fabric of JIS L1096. The growth rate of underwear varies depending on the type, but in general, most of them have a growth rate of about 20% to 40%. As with underwear, it expands and contracts to improve fit and reduce misalignment.

As a second means of forming the elastic region 6, as shown in FIGS. 4 and 5, a men's absorbent article is provided between the skin-side upper layer sheet 10 and the non-skin-side lower layer sheet 11. A plurality of filamentous elastic elastic members 9, 9 ... Are arranged along the width direction of 1 and at intervals in the vertical direction orthogonal to the width direction.
Explaining a specific method for manufacturing the elastic region 6 according to the second means, as shown in FIGS. 4 and 5, there is a vertical gap between the upper layer sheet 10 and the lower layer sheet 11. The filamentous elastic elastic members 9, 9 ... Are arranged along the width direction. Of these thread-like elastic stretchable members 9, the stretchability is increased by deactivating the stretchability of the thread-like elastic stretchable member 9 ... at the portion overlapping the absorber 4 in the thickness direction by using the above-mentioned deactivating means. It is possible to obtain the elastic region 6 in which the filamentous elastic elastic member in the activated state is arranged around the absorber 4. Further, the region not imparting elasticity provided on the peripheral edge of the elastic sheet 5 is formed by not arranging the thread-like elastic elastic member 9 or adhering it to the upper layer sheet 10 and the lower layer sheet 11. Can be done. Here, "the elastic elastic elastic member 9 is deactivated" means that the elastic elastic elastic member 9 is finely cut at predetermined intervals by a discontinuity means described later, or the elastic elastic elastic member 9 is predetermined. By continuously adhering to the upper layer sheet 10 and the lower layer sheet 11 over the section of the above, the elastic force of the thread-like elastic elastic member 9 does not function or the function is significantly reduced. In order to cut the thread-like elastic stretchable member 9 into small pieces, for example, the thread-like elastic stretchable member 9 is cut at intervals of 1 to 10 mm, preferably at intervals of 1 to 5 mm, according to a predetermined cut pattern.
In order to cut and discontinue the thread-like elastic stretchable member 9 ..., a sheet in which the thread-like elastic stretchable member 9 ... is arranged between the upper layer sheet 10 and the lower layer sheet 11 is manufactured, and then a convex portion is formed on the surface thereof. The sheet is passed between a cutter roll in which a plurality of cutters are arranged on the convex portion and the opposing roll facing the cutter roll, and the thread-like elastic elastic member 9 at a predetermined portion of the sheet is formed on the convex portion of the cutter roll and the convex portion. It cuts by at least one of pressurization and heating between facing rolls. The facing roll should be separated from the cutter roll so that the cutter portion is lowered by the rotation of both rolls and comes into contact with only the cutter portion of the cutter roll.

The filamentous elastic elastic member 9 may be continuously adhered to the upper layer sheet 10 and the lower layer sheet 11, or may be intermittently adhered to the upper layer sheet 10. When the adhesive is applied at substantially equal intervals along the filamentous elastic elastic member 9 and intermittently adhered, the upper layer sheet 10 and the lower layer sheet 11 are bonded because the portion to which the filamentous elastic elastic member 9 is adhered is dented. It is preferable because the non-existing portion is formed in a protruding pleated shape, which improves the appearance.

As shown in FIG. 4, when the stretchable region 6 is formed around the absorber 4 over the entire circumference, the stretchable region (region A in the figure) that overlaps with the absorber 4 in the width direction is stretched. It is preferable to set the force so as to be larger than the expansion / contraction force of the region (region B in the figure) that does not overlap with the absorber 4 in the width direction. The ratio of the stretching force of the A region to the stretching force of the B region is preferably about 1.5 to 10: 1 of the stretching force of the A region: the stretching force of the B region. In order to change the elastic force in the A region and the B region, in the form in which the elastic region 6 shown in FIG. 4 is composed of the filamentous elastic elastic member 9, the elongation rate of the filamentous elastic elastic member 9 is greatly increased in the A region in the B region. It can be made smaller, or it can be made by disposing a separate filamentous elastic elastic member 9 having different elastic forces in the A region and the B region.

By setting the stretching force of the A region to be larger than the stretching force of the B region, the region overlapping with the absorber 4 in the width direction contracts more, and the absorber 4 easily adheres to the penis and is absorbed by men. A pocket-like space in which the absorber 4 bulges to the non-skin side is likely to be formed on the skin side of the sex article 1, and the protruding penis is accommodated in this space, so that the absorbent body 4 and the penis adhere to each other. Will improve more.

As shown in FIG. 4, the elastic region 6 is formed by disposing a plurality of filamentous elastic elastic members 9 ... Between the upper layer sheet 10 on the skin side and the lower layer sheet 11 on the non-skin side. In this case, the arrangement form of the upper layer sheet 10 and the lower layer sheet 11 is preferably any of the following. In the first form, as shown in FIG. 5, the upper layer sheet 10 and the lower layer sheet 11 are composed of separate sheets, and the upper layer sheet 10 and the lower layer sheet 11 having substantially the same planar shape are aligned at the edges. It is a laminated product. In this first embodiment, since the upper layer sheet 10 and the lower layer sheet 11 can be used in the same planar shape, the production can be simplified and the material cost can be reduced.

Next, in the second arrangement form of the upper layer sheet 10 and the lower layer sheet 11, as shown in FIG. 6A, the upper layer sheet 10 and the lower layer sheet 11 are composed of separate sheets, and the upper and lower layers of the upper layer sheet 10 are vertically arranged. Both ends in the direction wrap around the edge of the lower layer sheet 11 so as to extend to the non-skin side of the lower layer sheet 11. As a result, the edges of the upper sheet 10 and the lower sheet 11 do not come into contact with the skin surface, and the edges of the lower sheet 11 are covered by the folded portion of the upper sheet 10 extending to the non-skin side. Therefore, the edge of the sheet does not come into contact with the skin surface, and the feeling of discomfort during wearing can be reduced.

As an example of this modification, as shown in FIG. 6B, both ends of the lower layer sheet 11 in the vertical direction wrap around the edge of the upper layer sheet 10 so as to extend to the skin side of the upper layer sheet 10. You may do it. When the lower layer sheet 11 is folded back toward the skin side, it is arranged between the laminated body in which the absorber 4 is interposed between the leak-proof sheet 2 and the liquid-permeable surface sheet 3 and the upper layer sheet 10 as shown in the illustrated example. Alternatively, although not shown, it may be arranged so as to cover the skin side of the laminated body (the skin side of the liquid permeable surface sheet 3). The latter is a preferable form in that leakage from the vertical edge of the absorber 4 can be more reliably prevented.

Further, as a third arrangement form of the upper layer sheet 10 and the lower layer sheet 11, as shown in FIG. 7, the upper layer sheet 10 and the lower layer sheet 11 are configured as an integral sheet, and the upper end of the men's absorbent article 1 is formed. Or it is configured by folding back at the lower end. In this embodiment, since the upper layer sheet 10 and the lower layer sheet 11 can be configured as an integral sheet, the manufacturing can be simplified and the material cost can be reduced.

The stretchable region 6 may be formed to be stretchable only in the width direction of the men's absorbent article 1, or may be stretchable in both the width direction of the men's absorbent article 1 and the vertical direction orthogonal to the width direction. It may be formed. In order to form the former stretchable only in the width direction, in the form in which the stretchable region 6 shown in FIG. 1 is made of the stretchable sheet 5 itself, the stretchable sheet 5 having stretchability in only one direction is used. In the form in which the elastic region 6 shown in FIG. 4 is composed of the thread-like elastic stretchable member 9, the thread-like elastic stretchable member 9 is arranged along the width direction of the men's absorbent article 1. Can be done by. On the other hand, in order to form the latter absorbent article 1 for men so as to be stretchable in the width direction and the vertical direction, in the form of the stretchable sheet 5 itself shown in FIG. 1, the stretchable sheet 5 itself is stretchable in two orthogonal directions. It can be made by using the elastic sheet 5 having the above, and in the form in which the filamentous elastic elastic member 9 shown in FIG. 4 is arranged, as shown in FIG. 8, in the width direction of the absorbent article 1 for men. A plurality of filamentous elastic elastic members 9 ... Are arranged along the vertical direction and at intervals in the vertical direction, and a plurality of filamentous elastic elastic members 9 ... Can be achieved by arranging. As described above, by having elasticity in the width direction and the vertical direction of the men's absorbent article 1, the absorber 4 can be more reliably fitted to the penis portion, and the leakage of body fluid can be prevented more reliably.

<Slip prevention layer>
On the non-use surface side (non-skin surface side) of the elastic sheet 5, a slip prevention layer 7 is arranged in a predetermined area, and the men's absorbent article 1 is fixed to underwear or the like when it is attached to the body. ing. As the slip prevention layer 7, a mechanically bonded hook material may be used, or an adhesive may be used.

As shown in FIGS. 1 and 2, the slip-preventing layer 7 is located at both side positions outside the stretchable region 6 in the width direction, respectively, along the vertical direction of the men's absorbent article 1, substantially in the vertical direction. It is provided one by one in a continuous band shape over the entire length. That is, the slip prevention layer 7 is a region that does not overlap the stretchable region 6 and the men's absorbent article 1 in the thickness direction, and is provided outside the stretchable region 6 in the width direction of the men's absorbent article 1. There is. As a result, both ends of the absorbent article 1 for men in the width direction do not deviate from the underwear, and the elastic region 6 of the absorbent article 1 for men extends in accordance with the elongation of the underwear by the male genitalia. Further, since the slip prevention layer 7 is provided over substantially the entire length of the men's absorbent article 1 in the vertical direction, in detail, at least over the vertical range in which the elastic region 6 is arranged. The stretchable region 6 can be expanded and contracted starting from the portion fixed to the underwear by the slip prevention layer 7.

As shown in FIG. 1, the slip prevention layer 7 may be provided at least at both ends in the width direction of the men's absorbent article 1, but in addition to this, as shown in FIG. 9, absorption. A single line of slip prevention layer 12 may be provided at the center of the body 4 in the width direction along the vertical direction. The slip prevention layer 12 is provided in a region where the absorbent body 4 and the absorbent article 1 for men overlap in the thickness direction, and is not provided in a region where the absorbent body 4 and the elastic region 6 overlap in the thickness direction. The displacement prevention layer 12 provided at the center of the absorber 4 in the width direction is provided in a region that does not hinder the expansion and contraction of the elastic region 6, so that the state in which the absorber 4 is located at the center in the width direction can be maintained. I have to. Therefore, the state in which the absorber 4 is in close contact with the penis can be more reliably maintained.

In the men's absorbent article 1 having the above configuration, an elastic region 6 that can be expanded and contracted at least in the width direction is formed on the outer side in the width direction from the absorber 4, and underwear is formed on the outer side in the width direction from the elastic region 6. Since the slip-preventing layer 7 for fixing to the underwear is provided, when the men's absorbent article 1 is attached to the underwear, the elastic region 6 is aligned with the extension of the underwear by the protruding penis or scrotum. By stretching, the men's absorbent article 1 also stretches, so that the absorber 4 can be maintained in close contact with the penis. Therefore, the leakage of body fluid can be prevented, and the absorber 4 comes into direct contact with the penis due to the elastic force of the elastic region 6, so that a good wearing feeling similar to that of normal underwear can be obtained.
