  The present invention relates to an absorbent article.

  Conventionally, as an absorbent article for adults such as elderly people and persons with disabilities, disposable diapers and urine removing pads provided with a top sheet, a back sheet, and an absorbent body interposed between a part of both sheets Is widely used. As an absorbent article specialized for men, a male urine-absorbing pad of a type used by encasing male genitalia is known. This male urine-absorbing pad is an absorbent article comprising a topsheet, a backsheet, and an absorbent body, similar to conventional disposable diapers and urine-absorbing pads, but is not simply addressed to the wearer. It is characterized in that male genitalia are encapsulated.

  The urine collection pad for men as described above is used in a state where male genitalia are encapsulated, and therefore, compared with a disposable diaper, or a flat urine collection pad that is simply placed on an undergarment or diaper, excrement There is an advantage that the contact area with the skin of the wearer can be reduced, and skin troubles caused by excrement can be reduced.

By the way, when using a male urine collection pad, in consideration of the unstable position of the male genital device, the male urine collection pad can be molded into a bag shape and covered with the male genital device to prevent leakage. is there.
For example, a urine-absorbing article capable of preventing the leakage of urine from the bag body by suppressing the size in the longitudinal direction of the bag body, ensuring a wide internal space of the bag body, and improving the ability to absorb urine is realized. (For example, refer to Patent Document 1).

  Further, by providing a plate-like or linear elastic member that presses the male genital with elasticity at the time of buckling deformation along the opening of the bag, a male urine removing pad that is difficult to remove the male genital from the bag is provided.

  Hereinafter, an absorbent article which is an embodiment of the present invention will be described in detail with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.

(First embodiment)
The absorbent article of 1st Embodiment of this invention is demonstrated based on FIG.1, FIG.2, FIG.3, FIG.4 and FIG.

  The absorbent article is, for example, a urine collecting pad for men for night or for a long time, and can be used detachably and interchangeably together with an outer body (not shown) attached to a human body such as a diaper, a diaper cover, and a pant. Is done.

  As shown in the developed view of FIG. 1, the absorbent article 100 includes an absorbent part 2 and an absorbent article that constitute a front part and a rear part of the absorbent article 100 on a substantially rectangular liquid-impermeable back sheet 1. It is divided into an absorbent portion 3 constituting both side surface portions of 100 and an absorbent portion 4 constituting the bottom surface portion of the absorbent article 100.

  Specifically, the absorbent portion having the absorber is formed in a substantially rectangular shape in a portion excluding the peripheral edge on the substantially rectangular back sheet 1 (or a top sheet not shown), and the hatched portion in FIG. Remove the P1 and P2 absorbers. Incidentally, the hatched portions P1 and P2 in FIG. 1 may be manufactured so as not to be formed from the beginning, instead of removing the absorber once formed.

  Then, the embossing E1, E2, E3 and E4 are formed in the longitudinal direction of the absorption part, the absorption part is divided into the absorption part 2 and the four absorption parts 3, respectively, and further the embossing E5 in the short direction of the absorption part, E6 and E7 are formed, and the absorption part 4 is separated from the absorption part 2 to form two absorption parts 2 and 4, respectively.

  Finally, it is four formed absorption parts 3, Comprising: The center of the longitudinal direction of the absorbent article 100 toward the periphery of the absorbent article 100 from the part close | similar to the absorption part 4 among each four corners (FIG. Embosses E8, E9, E10, and E11 are formed so as to be curved toward the III-III) side in FIG.

  In addition, a liquid-permeable surface sheet (not shown) that allows permeation of liquid such as urine is formed on the absorbent parts 2 to 4 that are divided and formed in this way, and the periphery of the absorbent article 100 The top sheet and the back sheet are bonded together by a hot melt adhesive, heat sealing, ultrasonic sealing, or the like.

  For this reason, as shown in FIG. 2, the absorbing portions 2 and 3 in the II-II cross section in FIG. 1 have a structure interposed between the top sheet 5 and the back sheet 1.

The top sheet 5 is formed of a perforated or non-porous nonwoven fabric, a porous plastic sheet, or the like. As a raw material fiber constituting the nonwoven fabric, synthetic fibers such as polyethylene or polypropylene, synthetic fibers such as polyester or polyamide, recycled fibers such as rayon or cupra, and natural fibers such as cotton can be used. In addition, as a method for producing the nonwoven fabric, a known method can be used as appropriate, and examples thereof include a spunlace method, a spunbond method, a thermal bond method, a melt blow method, a needle punch method, or a combination of these methods. .
When a large number of through-holes are formed in the top sheet, liquid such as urine is absorbed more quickly, and the dry touch property is excellent.

  The back sheet 1 is not particularly limited as long as it is a liquid-impervious material. For example, a plastic film made of an olefin resin such as polyethylene or polypropylene, or a plastic film is provided on the surface of the nonwoven fabric. A laminated nonwoven fabric, a laminated sheet in which a nonwoven fabric or the like is laminated on a plastic film, and the like can be used. In addition, by applying heat and pressure to reduce the voids of the fiber, or by applying a highly water-absorbent resin or hydrophobic resin or water repellent, a sheet that is liquid-impervious without using a plastic film It can be used as a back sheet.

  The absorber which the absorption parts 2-4 have absorbs water-like components, such as urine, can be formed with the aggregate | assembly of a fiber, for example. As this fiber assembly, a filament assembly obtained by opening, as necessary, synthetic fiber tows (fiber bundles) such as cellulose acetate as well as short fibers such as cotton-like pulp and synthetic fibers Can also be used. Moreover, a super absorbent polymer (SAP; Super Absorbent Polymer) can be combined with a fiber assembly, and an absorber can also be comprised.

Examples of superabsorbent resins (hereinafter simply referred to as polymers) include carboxymethylcellulose, polyacrylic acid and its salts, crosslinked acrylate polymers, starch-acrylic acid graft copolymers, and starch-acrylonitrile graft copolymers. A hydrolyzate, a polyoxyethylene cross-linked product, a carboxymethyl cellulose cross-linked product, a partially cross-linked water-swellable polymer such as polyethylene oxide and polyacrylamide, or a copolymer of isobutylene and maleic acid is preferably used.
Furthermore, in order to give a deodorant function, you may put a deodorizer in an absorber. As the deodorant, for example, activated carbon, natural minerals (for example, bennite, kaolinite, kanemite, etc.) and synthetic inorganic substances (zeolite, amorphous silica, etc.) can be used.

  Then, the absorbent article 100 formed as shown in the developed view shown in FIG. 1 is bent so that the topsheet 5 comes to the inside at the center (III-III in FIG. 1) in the longitudinal direction of the absorbent article 100. As shown in FIG. 3, the absorbent article 100 is completed as a product by forming the seal portion 6 and bonding the surface sheet 5 side together.

  Specifically, the seal portion 6 is a peripheral sheet of the absorbent article 100, and the peripheral sheet is a portion close to the side of the absorbent portion 2, in other words, a portion where an opening is formed, and a surface sheet other than a bent portion. The 5 side is bonded with a hot melt adhesive, heat seal, ultrasonic seal or the like.

  Here, the use state etc. of the absorbent article 100 will be described with reference to FIGS. 4 and 5. When mounting, the part of the fan-shaped absorption part 3 divided by the embosses E8, E9, E10 and E11 curved as shown by the arrows in FIG. 3, in other words, the lower part of the absorption part constituting both side parts is pressed from the left and right. As a result, the absorbent article 100 is bent inward at the formed embossed portions E1, E2, E3, and E4, and a box-shaped internal space is formed as shown in the perspective view of FIG.

  In particular, the absorbing portion 3 forming both side portions is not integrated, but is divided by curved embosses E8, E9, E10 and E11, and the fan-shaped absorbing portion 3 is formed at the lower part of both side portions, so that the pressed force is reduced. It becomes easy to concentrate on the lower part of both side surface portions, and can be easily bent at the portions of the embosses E1, E2, E3, and E4.

  That is, the front and back walls are formed by the two absorbing portions 2, and the side walls are formed by the two absorbing portions 3 facing each other among the four absorbing portions 3. Further, a wall of the bottom surface portion is formed by the absorbing portion 4 and has a shape having an opening AP for inserting a male genitalia into a portion facing the bottom surface portion.

  Moreover, Fig.5 (a) has shown the outline | summary of the state which inserted the user's male instrument into opening part AP of the absorbent article 100 in which the box-shaped internal space was formed, The said absorbent article 100 is used. The side part of the absorbent article 100 is pressed from the thigh L, and the shape of the box-shaped internal space formed in the absorbent article 100 is maintained. It becomes a state suitable for doing.

  Incidentally, since the gap between the thighs L of Japanese men on the average is about 40 mm to 60 mm, the width in the short direction of the absorbent part 2 is preferably about 50 mm.

  Moreover, at the time of urination, as shown in FIG. 5 (b), the internal space formed in the absorbent article 100 has already been formed at the time of wearing the male genitalia P, and compared with the conventional example Because it is wide, even if the momentum of urination is strong or the amount of excretion is large, the urine U is temporarily stored in the inner space, particularly the bottom portion formed by the absorption part 4 It is possible to prevent urine leakage from the opening AP which is a mounting portion at once.

  Further, by not providing the absorber in the hatched portion P1 in FIG. 1, the hatched portion P1 becomes a gusset, and the emboss formed on the absorbent article 100 when the portion of the fan-shaped absorber 3 is pressed from the left and right. The portions E1, E2, E3, and E4 are easily bent. Furthermore, by not providing an absorber in the hatched portion P1 in FIG. 1, it is possible to prevent urine from being absorbed and the absorber from bulging and narrowing the internal space where the bent corner is formed.

  Further, by not providing the absorber in the hatched portion P2 in FIG. 1 and forming the seal portion 6 in the hatched portion P2, specifically, it is the periphery of the absorbent article 100, and the periphery is absorbed. Since the portion close to the side of the portion 2 and the surface sheet 5 side other than the bent portion are bonded together, the opening AP formed in the absorbent article 100 can be narrowed as a result, and the opening that is a mounting portion The risk of urine leakage from the AP can be reduced.

  As mentioned above, in 1st Embodiment of this invention, the absorption part which has the absorber interposed between the surface sheet 5 and the back surface sheet 1, the absorption part 2 which comprises a front part and a back part, both sides When the absorbent portion 3 constituting the surface portion and the absorbent portion 4 constituting the bottom surface portion are divided and the lower portions of the both side surface portions are pressed from the left and right, the internal space and the opening AP are formed in the absorbent article, and the opening AP By inserting and using the male genitalia, the urinated urine is temporarily stored in the internal space, and urine leakage from the mounting portion can be prevented.

(Modification 1)
A first modification of the first embodiment of the present invention will be described with reference to FIGS. In addition, about the description which overlaps with 1st Embodiment mentioned above, description is abbreviate | omitted suitably.

  As shown in the development view of FIG. 6, the absorbent article 101 that is Modification 1 is an absorbent section that forms a front part and a back part of the absorbent article 101 on a substantially rectangular liquid-impermeable back sheet 1. 7. Absorbing part 8 constituting both side parts of absorbent article 101 and absorbent part 9 constituting the bottom part of absorbent article 101 are formed. In addition, since the fundamental arrangement | positioning etc. of the absorption part which has the absorber interposed between the surface sheet 5 and the back surface sheet 1 are the same as 1st Embodiment, the description is abbreviate | omitted.

  The difference from the first embodiment is that a slit 10 is formed by removing the absorber of the absorber 7 at the center of the absorber of the two absorbers 7.

  Specifically, as shown in FIG. 6, two absorption portions 7, each of which has a cut-out portion on the side close to the absorption portion 9 forming the bottom surface portion, and faces the sides. The slit 10 is formed so that the slit width becomes narrower toward the side (opening side).

  Note that, similarly to the first embodiment, the absorbent article 101 formed as shown in the development view shown in FIG. 6 is folded and overlapped so that the topsheet 5 comes to the inner side at the central portion in the longitudinal direction of the absorbent article 101. At the same time, as shown in FIG. 3, the absorbent article 101 is completed as a product by forming the seal portion 6 and bonding the top sheet 5 side.

  For this reason, as shown in FIG. 7, the absorbing portions 7 and 8 in the VII-VII cross section in FIG. 6 have a structure interposed between the top sheet 5 and the back sheet 1, and the slit 10 portion. The absorber of the absorption part 7 is removed. Incidentally, the slit 10 may be one in which the absorber is removed once the absorbing portion 7 is formed, or one in which the absorber is not formed in the slit 10 from the beginning.

  That is, in the absorbent article 101 which is the modified example 1, the slit 10 from which the absorbent body of the absorbent portion 7 is removed is formed in the central portion of the absorbent portion 7 so that the slit width gradually decreases from the bottom toward the opening. Therefore, at the bottom of the formed internal space, the absorption effect by the absorber is small, the reduction of the internal space due to the expansion of the absorber is suppressed, and the urinated urine is easily collected, and the bottom is collected at the bottom It becomes easy to guide urine toward the opening.

  In addition, urine collected at the bottom of the internal space of the absorbent article 101 is sequentially guided toward the opening, and the absorber present in the portion absorbs urine and expands, so that the vicinity of the opening that is the mounting portion is increased. The gap is reduced, and the effect of preventing urine leakage is further increased.

  As described above, in the first modification of the present invention, the same effect as that of the first embodiment is achieved, and the slit 10 from which the absorber of the absorber 7 is removed is formed in the center of the absorber 7 from the bottom to the opening. By forming the slit width to become narrower toward the bottom, it is possible to suppress the reduction of the internal space due to the expansion of the absorber at the bottom, and the urinated urine is easily collected, and the urine collected at the bottom is opened. It becomes easy to guide in the direction.

(Modification 2)
Modification 2 of the first embodiment of the present invention will be described with reference to FIGS. In addition, about the description which overlaps with 1st Embodiment and the modification 1 which were mentioned above, description is abbreviate | omitted suitably.

  The absorbent article 102 which is the modified example 2 is basically the same as the modified example 1 and is different in that the absorbent portion has a two-layer structure.

  That is, as shown in the development view of FIG. 8, the upper layer of the absorbent part having the absorber in contact with the top sheet 5 has the absorbent parts 11 to 13 and the slits 14 having the same configuration as that of the modified example 1, and the back sheet In the lower layer of the absorption part which has the absorber which touches 1, absorption parts 15-17 are formed in the same shape and the same position as absorption parts 11-13, respectively.

  Specifically, the developed view shown in FIG. 8 is overlapped so that the absorbent portions are in contact with each other, and the topsheet 5 is placed inside at the central portion in the longitudinal direction of the absorbent article 102 as in the first embodiment. As shown in FIG. 3, the absorbent article 102 is formed by forming the seal portion 6 and bonding the top sheet 5 side.

  Therefore, as shown in FIG. 9, the structure is interposed between the top sheet 5 and the back sheet 1, and there is no slit in the absorber 15, which is the lower layer in the IX-IX cross section in FIG. 9. Instead, the absorber of the absorbing portion 11 in the slit 14 portion of the upper absorbing portion 11 is removed.

  In the absorbent article 102 which is the modified example 2, since the absorbing part 15 is present in the lower layer of the slit 14, the absorption of urine in the slit 14 part can be supplemented as compared with the modified example 1.

  As described above, the second modification of the present invention has the same effects as those of the first embodiment and the first modification, and the slit 14 in which the absorbent body of the absorbent section 11 is removed at the center of the upper absorbent section 11. Since the slit portion is formed so that the slit width gradually decreases from the bottom toward the opening, and no slit is provided in the lower absorption portion 15, the absorption portion 15 exists in the lower layer of the slit 14. Compared with the above, urine absorption in the slit 14 portion can be supplemented.

(Modification 3)
Modification 3 of the first embodiment of the present invention will be described with reference to FIGS. 10 and 11. In addition, about the description which overlaps with 1st Embodiment mentioned above, the modification 1, and the modification 2, description is abbreviate | omitted suitably.

  The absorbent article 103 which is the modified example 3 is basically the same as the modified example 1 except that a polymer part which is an absorber is separately formed on the absorbent part and in the vicinity of the opening. .

  That is, as shown in the development view of FIG. 9, on the back sheet 1, there are the absorbent portions 11 to 13 and the slits 14 having the same configuration as that of the modified example 1, and the polymer that is the absorbent portion in the vicinity of the opening. The part 18 is formed separately.

  Specifically, as illustrated in FIG. 11, the structure is interposed between the top sheet 5 and the back sheet 1, and an absorber is provided on the absorber 11 in the XI-XI cross section in FIG. 11. The polymer portion 18 is further laminated to form a structure.

  As in the first embodiment, the absorbent article 103 formed as shown in the development view shown in FIG. 11 is folded and overlapped so that the topsheet 5 is located on the inner side in the central portion of the absorbent article 103 in the longitudinal direction. At the same time, as shown in FIG. 3, the absorbent article 103 is completed as a product by forming the seal portion 6 and bonding the top sheet 5 side.

  In the absorbent article 103 which is the modified example 3, since the polymer portion 18 which is an absorber is separately formed in the vicinity of the opening, the amount of absorption in the polymer portion 18 increases and is guided toward the opening by the slit 14. The polymer portion 18 that is the absorbent absorbs the expanded urine and expands, thereby narrowing the gap of the opening, reducing the risk of urine leakage from the opening that is the mounting portion, and When the polymer part 18 which is an expanded absorbent body and the male genitalia are fitted, the absorbent article 103 is hardly detached from the male genitalia.

  As described above, the third modification of the present invention has the same effects as those of the first embodiment and the first modification, and separately forms the polymer part 18 that is an absorber in the vicinity of the opening, thereby providing a polymer part. The amount of absorption at 18 increases, and the polymer portion 18 that is an absorbent that has absorbed and expanded urine reduces the risk of urine leakage from the opening as the mounting portion by narrowing the gap between the openings. it can. Moreover, the polymer part 18 which is an expanded absorbent body and the male genital fit can prevent the absorbent article 103 from falling off the male genitalia.

  In the description of the first embodiment, as shown in FIG. 1, the explanation is made using a development view in which the absorbers are not provided in the hatched portions P1 and P2, but the absorber is provided in the hatched portions P1 and P2. Even with such a structure, an internal space can be formed in the absorbent article 100, and therefore an absorber may be provided in the hatched portions P1 and P2.

  In the description of the first embodiment, E1 to E11 are described as embossing, but of course, a slit may be used. That is, as long as the absorbing portion is easily bent inward at the portions E1 to E11 and a box-like internal space is formed as shown in the perspective view of FIG.

  In the description of the first embodiment, E1 to E11 are formed continuously. However, there is no need to form them continuously. The absorption part may be easily bent inward at E11 and a box-like internal space is formed as shown in the perspective view of FIG.

  In the description of the first embodiment, the third absorbent portion is divided into two parts by E6, but the top sheet 5 is at the center (III-III in FIG. 1) in the longitudinal direction of the absorbent article 100. As long as it can be folded and stacked so as to be inside, the third absorbent portion may be integrated without being divided into two.

  Further, in Modification 3, the polymer portion 18 that is an absorber is provided by being laminated on the absorption portion 11, but the polymer portion 18 itself may be configured to include the absorption portion 11 portion, or The absorption part 11 may be formed thick on the back sheet 1 by forming the absorption part 11 thick without providing the polymer part 18 separately.
