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

As shown in FIGS. 1 to 3, the absorbent article 1 for men according to the present invention has a liquid-impermeable back sheet 2 made of a polyethylene sheet, a polypropylene sheet, or the like, and a permeable material that rapidly permeates body fluids such as urine. An absorber 4 composed of a liquid surface sheet 3, cotton-like pulp or synthetic pulp interposed between the two sheets 2 and 3, and the absorber 4 for maintaining the shape and improving the diffusivity of the absorber 4. It is composed of an encapsulating sheet 5 made of crepe paper or non-woven fabric that covers at least the skin side surface and the non-skin side surface. Further, around the absorber 4, the outer edge portion of the impermeable back sheet 2 and the liquid permeable surface sheet 3 is bonded by an adhesive such as hot melt, a heat seal, an ultrasonic seal or the like. , A flap portion F in which the absorber 4 does not exist is formed on the outer periphery.

Hereinafter, the structure of the absorbent article 1 for men will be described in more detail.
As the impermeable back 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, and further A non-woven fabric sheet (in this case, the waterproof film and the non-woven fabric form an impermeable back sheet) can be used after substantially ensuring the impermeable property by interposing a waterproof film. 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 impermeable back sheet 2 and the liquid-permeable front sheet 3 is, for example, a pulp in which a highly water-absorbent resin is mixed, or a pulp in which chemical fibers are mixed. , A mixture of highly absorbent resin is used. As shown in the figure, it is desirable that the absorber 4 is covered with an encapsulating sheet 5 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.

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. The content of the highly water-absorbent resin is preferably 5 to 60% of the weight of the absorber. If the content of the high water-absorbent resin is less than 5%, sufficient absorption capacity cannot be provided, and if it exceeds 60%, the entanglement between the pulp fibers disappears, the sheet strength decreases, and tears and cracks occur. Is likely to occur.

When the encapsulating sheet 5 covering the absorber 4 is provided as in this example, as a result, the encapsulating sheet 5 is interposed between the liquid-permeable surface sheet 3 and the absorber 4. When the encapsulated sheet 5 is made of crepe paper, the encapsulated sheet 5 having excellent absorbability rapidly diffuses urine and prevents the urine from regurgitating.

It is preferable that either or both of the absorber 4 and the encapsulating sheet 5 have 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, one or both of the absorber 4 and the encapsulating sheet 5 may be colored by containing activated carbon. This makes it possible to add the deodorizing effect of activated carbon.

As shown in FIGS. 4 and 5, the men's absorbent article 1 is used by being attached to the skin contact surface at the center of the front body of the front opening type men's underwear 30. The front body of the men's underwear 30 is provided with a placket opening 33 formed by superimposing a front placket portion 31 and a back placket portion 32.

The men's underwear 30 is preferably a boxer-type men's underwear provided with the placket opening 33 having a double structure of a front placket portion 31 and a back placket portion 32. In the placket opening 33, a front opening end edge 33a that opens toward the right side of the wearer is formed on the front side (non-skin contact surface side) of the men's underwear 30, and the back side of the men's underwear 30 ( On the skin contact surface side), a back side opening edge 33b that opens toward the left side of the wearer is formed.

The men's absorbent article 1 has a front opening portion in which a part of the men's absorbent article 1 is divided into left and right at a portion corresponding to the placket opening 33 of the men's underwear 30 along the placket opening 33. 10 is formed. The men's absorbent article 1 has a split portion 11 on one side with respect to the left-right direction in the vertical range in which the front-opening portion 10 is formed by forming the front-opening portion 10 (FIG. 1). The portion existing on the right side of the front opening portion 10 in the plan view from the skin contact surface side shown in FIG. 1 and the other side split portion 12 (the front opening portion in the plan view from the skin contact surface side shown in FIG. 1). It will be divided into (the part existing on the left side of 10).

As shown in FIG. 2, an adhesive layer 13 is formed on the outer surface side of the impermeable back sheet 2 of the one-side split portion 11 at least in the vicinity of the front opening portion 10. Further, on the outer surface side of the impermeable back sheet 2 of the other side split portion 12, the adhesive layer 14 is similarly formed at least in the vicinity of the front opening portion 10. Further, in the absorbent article 1 for men, one or more adhesive layers 15 separated from the pressure-sensitive adhesive layer 13 in the left-right direction, one pressure-sensitive adhesive layer 15 in the illustrated example, are vertically separated from the pressure-sensitive adhesive layer 13 in the one-side split portion 11. Two pressure-sensitive adhesive layers 16 and 16, which are formed along the same direction and are separated from each other in the left-right direction in the illustrated example, are formed in a region below the front opening portion 10. Further, although not shown, a pressure-sensitive adhesive layer may be formed on the other side split portion 12 in addition to the pressure-sensitive adhesive layer 14. These pressure-sensitive adhesive layers 13 to 16 are for attaching the men's absorbent article 1 to the inner surface of the men's underwear 30.

As shown in FIGS. 4 and 5, the adhesive layer 13 formed on the one-side split portion 11 is attached to the back side placket portion 32 of the men's underwear 30 and is formed on the other-side split portion 12. The adhesive layer 14 is attached to the front placket portion 31 of the men's underwear 30 extending to the outside of the back side opening edge 33b. That is, the front opening portion 10 of the men's absorbent article 1 is arranged at a position substantially coincident with the back side opening end edge 33b of the placket opening 33 of the men's underwear 30, and is placed on both sides of the back side opening end edge 33b. Adhesive layers 13 and 14 located on both sides of the front opening portion 10 are attached to the back side placket portion 32 and the front side placket portion 31, respectively.

With the above configuration, in the men's absorbent article 1, as shown in FIG. 5 (B), the placket opening of the men's underwear 30 is used to remove the penis from the placket opening 33 of the men's underwear 30 when urinating. When the front side placket portion 31 and the back side placket portion 32 are expanded to the left and right from the front side opening end edge of 33, the one-side split portion attached to the front side placket portion 31 and the back side placket portion 32, respectively, in conjunction with this. The 11 and the other side split portion 12 expand to the left and right, respectively, to form an opening that integrally penetrates the men's underwear 30 and the men's absorbent article 1. Therefore, when urinating, the penis can be easily taken out from the placket opening 33 of the men's underwear 30.

In addition, this men's absorbent article 1 is not a type that wraps around the entire waist, but a type that is attached to the placket of men's underwear 30 that is usually worn, so even people with mild incontinence may have mild incontinence. Less likely to cause discomfort when worn.

In the front opening portion 10, the one-side split portion 11 and the other-side split portion 12 do not have to overlap, but as shown in FIG. 1, the one-side split portion 11 and the other-side split portion 12 overlap each other. It is preferable that they are arranged in such a manner. By arranging the one-side split portion 11 and the other-side split portion 12 so as to overlap each other, leakage of body fluid from the front opening portion 10 is less likely to occur. From the viewpoint of more reliably preventing the leakage of body fluid from the front opening portion 10, it is preferable to arrange the absorbers 4 of the one-side split portion 11 and the other-side split portion 12 so as to overlap each other at least in part.

The overlapping width A between the one-side split portion 11 and the other-side split portion 12 at the upper end edge of the front opening portion 10 is preferably 10 to 20 mm. If the overlapping width A is too large, it becomes difficult for the front opening portion 10 to open, and it becomes difficult for the penis to be taken in and out. On the other hand, if the overlap width A is too small, body fluid tends to leak from the front opening portion 10.

In the men's absorbent article 1 according to the present embodiment, the men's absorbent article 1 extends above the front opening portion 10 of the one-side split portion 11 between the upper outline of the men's absorbent article 1 above the front opening portion 10. A joint portion 17 is provided in which a portion to be formed and a portion extending above the front opening portion 10 of the other side split portion 12 are joined by an adhesive such as hot melt or a joining means such as a heat seal or an ultrasonic seal. Has been done. By providing the joint portion 17, the positions of the one-side split portion 11 and the other-side split portion 12 in the front opening portion 10 can be fixed to some extent, and the leakage of body fluid from the front opening portion 10 and the front opening portion 10 are unintentional. It is possible to prevent the mouth from opening.

The vertical distance B from the upper end of the men's absorbent article 1 to the upper edge of the front opening portion 10 is preferably 30 to 40 mm.

The front opening portion 10 is preferably formed in a range from a position below the upper end of the men's absorbent article 1 to an intermediate position in the vertical direction of the men's absorbent article 1, more preferably than the front opening portion 10. It is preferable that the upper portion and the lower portion are continuously formed on the left and right sides, respectively. As a result, when the front side placket portion 31 and the back side placket portion 32 of the men's underwear 30 are spread to the left and right, the interlocking of the one-side split portion 11 and the other-side split portion 12 of the men's absorbent article 1 is enhanced, and urination is performed. At this time, it becomes easier to remove the penis from the placket opening 33 of the underwear.

The length L of the front opening portion 10 is preferably 110 to 120 mm. Since the length of the placket opening 33 of general boxer type men's underwear is about 110 mm, it is preferable to form the placket opening 33 equal to or slightly longer than the placket opening 33 of the men's absorbent article 1.

As shown in FIG. 1, the front opening portion 10 is preferably formed at a position deviated to the left side of the vertical center line CL in a plan view from the skin contact surface side. As shown in FIG. 4, the back opening end edge 33b of the placket opening 33 of the general men's underwear 30 is provided at a position deviated to the right side from the center of the men's underwear 30. It is better to provide it.

Further, it is preferable that the front opening portion 10 is provided so as to be inclined to the left side at a predetermined angle with respect to the vertical center line CL corresponding to the back side opening end edge 33b of the placket opening 33 of the men's underwear 30. .. The inclination angle α with respect to the vertical center line CL is preferably 0 to 30 °. Since the inclination angle α of the back opening end edge 33b of the placket opening 33 of the general men's underwear 30 is around 10 °, it corresponds to this.

As shown in FIG. 1, the front opening portion 10 is formed at a position deviated to the left side of the vertical center line CL, and is provided so as to be inclined to the left side with respect to the vertical center line CL at a predetermined angle. By doing so, the one-side split portion 11 is formed in a larger area than the other-side split portion 12. As a result, the one-sided split portion 11 widely covers the crotch portion of the wearer when worn, and thus has a role of mainly absorbing urine due to incontinence or the like during wearing. Further, the other side split portion 12 has a role of absorbing urine due to incontinence at the time of wearing and the front side placket portion 31 when the penis is returned to the men's underwear after urination, like the one side split portion 11. It also has the role of preventing urine from adhering to the penis.

As shown in FIG. 1, the planar shape of the absorbent article 1 for men is preferably a substantially trapezoidal shape with a wide upper side and a narrow lower side in order to improve the fit to the crotch portion. In addition to this, it may be formed in an inverted triangular shape, a circular shape, an elliptical shape, a polygonal shape, or the like. The outer width of the upper side of the absorbent article 1 for men is preferably 170 to 200 mm, and the outer width of the lower side is preferably 70 to 80 mm.

As shown in FIGS. 2 and 4, the pressure-sensitive adhesive layers 13 and 14 arranged on both sides of the front opening portion 10 are preferably provided in a band shape inclined along the inclination of the front opening portion 10. As a result, the men's absorbent article 1 can be securely fixed to the men's underwear 30, and the interlocking with the placket opening 33 of the men's underwear 30 is improved.

The production of the absorbent article 1 for men can be carried out in the following steps. First, as shown in FIG. 6A, an absorber 4 having a predetermined shape in which the defect portion 18 of the absorber is formed from the position corresponding to the front opening portion 10 to the upper end is manufactured, and the absorber 4 of the absorber 4 is manufactured. The skin side surface and the non-skin side surface are covered with the liquid permeable front sheet 3 and the impermeable back sheet 2, respectively, and the liquid permeable surface sheet 3 and the impermeable liquid in the region other than the absorber 4 (the outer region of the dotted line portion). A full-circle seal is applied to join the back sheet 2. Next, as shown in FIG. 6B, a notch that integrally cuts the liquid-permeable front sheet 3 and the impermeable back sheet 2 along the central portion of the defective portion 18 of the absorber 4. Form line 19. After that, as shown in FIG. 6C, at the upper end of the front opening portion 10, the one-side split portion 11 and the other-side split portion 12 are overlapped with each other so as to have a predetermined overlapping allowance, and the front opening portion is joined. The joint portion 17 is provided in the region above 10. By superimposing the one-side split portion 11 and the other-side split portion 12 divided on the left and right in this way, the central portion of the men's absorbent article 1 is formed into a cup shape that bulges outward. When worn on the men's underwear 30, the wearing feeling is improved and the leakage of body fluid can be prevented.

As a male absorbent article 1 according to a modified example, as shown in FIG. 7, the front opening portion 10 of the one side split portion 11 superimposed on the skin contact surface side of the other side split portion 12 in the front opening portion 10. Along the line, a three-dimensional gather 20 standing on the skin side may be formed. The three-dimensional gather 20 is formed by a gather-forming nonwoven fabric 21 arranged along the front opening portion 10 and toward the inward side of the one-side split portion 11. The gather-forming nonwoven fabric 21 is joined to the skin contact surface side of the liquid-permeable surface sheet 3 along the edge portion of the front opening portion 10, and the inner side portion is substantially double folded back. The elastic elastic member 22 is arranged inside the double sheet in a state where both ends or appropriate positions in the longitudinal direction are fixed. In the gather-forming nonwoven fabric 21, the three-dimensional gathers 20 stand up on the skin side due to the contraction force of the elastic elastic member 22 by joining the upper and lower end portions to the skin contact surface side of the liquid-permeable surface sheet 3, respectively. It is formed. By forming the three-dimensional gather 20 along the front opening portion 10 of the one-side split portion 11, the penis enters between the one-side split portion 11 and the other-side split portion 12 in the front opening portion 10 at the time of mounting. The body fluid can be prevented from leaking, and the body fluid can be blocked by the three-dimensional gathers to prevent leakage from the end portion of the absorber 4. The three-dimensional gather 20 is preferably formed over the entire length of the front opening portion 10 from the upper end to the lower end of the front opening portion 10.

[Examples of other forms]
(1) In the above embodiment, the one-side split portion 11 and the other-side split portion 12 are overlapped to form the front opening portion 10, but as shown in FIG. 8, the one-side split portion 11 and the other side are formed. The front opening portion 10 may be configured by providing a notch portion 23 between the side division portions 12 without overlapping the side division portions 12. As a result, the step of superimposing the one-side split portion 11 and the other-side split portion 12 is eliminated, the manufacturing can be simplified, and the discomfort at the time of mounting can be reduced.

In the men's absorbent article 1 shown in FIG. 8A, an island-shaped defect portion 24 is formed in an intermediate portion not connected to the outer periphery of the absorber 4, and is the central portion of the defect portion 24 of the absorber 4.
