Description

  The present invention relates to an absorbent article and a packaging structure for the absorbent article.

  As the absorbent article, one having a structure including a top sheet, a leak-proof sheet, and an absorbent body between them is known. In such an absorbent article, for example, in the case of an absorbent article for men, it is necessary to increase the amount of absorption in the urination part, so that the absorber corresponding to the urination part is formed thicker than the other parts. Or increasing the amount of the superabsorbent resin in the portion corresponding to the urination portion is generally performed. Also, in the case of absorbent articles for women, in order to prevent back leakage, the absorber in the part corresponding to the rear part is formed thicker than the other part, or the composition of the superabsorbent resin in the part corresponding to the rear part It is common practice to increase the amount. However, in such an absorbent article, when the thickness of the individual package is increased in the folded state, extra vertical wrinkles enter the absorbent article in the expanded state, or the individual package is expanded. It may take time.

  Therefore, in such an absorbent article, it is preferable to form a part of the absorbent body larger than the other part.

[Absorbent articles]
With reference to FIG. 2 thru | or FIG. 8, the absorbent article 20 which concerns on embodiment of this invention, and its manufacturing method are demonstrated in detail. The absorbent article 20 according to the embodiment of the present invention is exemplified by a male urine-absorbing pad, but is not limited thereto, and the absorbent article 20 is female as long as the absorbent body is asymmetric in the longitudinal direction. Other absorbent articles such as sanitary napkins for nighttime and liners for incontinence may be used. In the description of the present specification, the longitudinal direction of the absorbent article is a direction extending forward and backward of the wearer when the absorbent article is worn, and the short direction of the absorbent article is transverse to the longitudinal direction or The direction is orthogonal. The longitudinal direction is the longitudinal direction of the absorbent article 20 in the deployed state, and the short direction is the direction transverse or orthogonal to the longitudinal direction of the absorbent article 20 during deployment. Furthermore, the length in the longitudinal direction is the length in the center portion in the short direction of the length measurement object, and the length in the short direction is the length in the center portion in the longitudinal direction of the length measurement object.

  Absorbent articles 20 shown as absorbent articles 20A, 20B, and 20C in FIGS. 2 to 6 are liquid-permeable surface sheets 200, 210, and 220, and absorbent bodies 100, 110, and 120, from the skin contact surface side. And a laminate including liquid impervious leakproof sheets 500, 510, and 520. Thereby, the absorber 100,110,120 has the structure enclosed by the surface sheet 200,210,220 and the leak-proof sheet 500,510,520. The absorbent article 20 may further include a liquid diffusive sheet between the liquid-permeable surface sheets 200, 210, and 220 and the absorbers 100, 110, and 120.

  Furthermore, as shown in FIGS. 2 and 3, the absorbent articles 20 </ b> A, 20 </ b> B, and 20 </ b> C may include a release sheet 300. The release sheet 300 is fixedly disposed on the side of the absorbent article 20 that faces the skin contact surface with an adhesive, an adhesive tape, or the like, and is removed when the absorbent article 20 is used. The release sheet 300 may be fixed to the leakproof sheets 500, 510, and 520. 4 to 7 also include the release sheet 300, but the illustration is omitted. As shown in FIG. 2, the release sheet 300 has an end portion of the release sheet 300 fixed by a tape portion 302, and a side edge sealing portion 304 corresponding to a side edge in the longitudinal direction of the absorbent article 20 is formed by heating or adhesion. By doing so, it may be a packaging sheet that wraps the absorbent article 20, and the adhesiveness is developed on the side of the absorbent article 20 that faces the skin contact surface without packaging. For this reason, the sheet may be peeled off. As the material of the release sheet 300, paper such as glassine paper or paraffin paper, or fibers such as nonwoven fabric is used.

  The top sheets 200, 210, and 220 are disposed to face the leak-proof sheets 500, 510, and 520 with the absorbers 100, 110, and 120 therebetween. Since the topsheets 200, 210, and 220 are sheets that come into contact with the skin, the topsheets 200, 210, and 220 are preferably formed of a material such as a non-woven fabric that has a soft feel and does not irritate the skin. Moreover, the leak-proof sheets 500, 510, and 520 have liquid impermeability as described above, and have a waterproof function that prevents liquid such as urine absorbed by the absorbers 100, 110, and 120 from leaking into the underwear. It is like that. As a material for such leak-proof sheets 500, 510, and 520, for example, a thin plastic film such as polyethylene is used.

  Although not shown, the liquid diffusive sheet is made of a relatively thick hydrophilic non-woven fabric. The liquid (for example, urine) dropped and introduced through the top sheets 200, 210, and 220 is, for example, in the longitudinal direction. Transport, diffuse and reduce liquid return.

  As shown in FIGS. 2, 4, and 6, the absorbers 100, 110, and 120 have a strip shape having an asymmetric shape in the longitudinal direction and a symmetric shape in the lateral direction. The absorbers 100, 110, and 120 are made of a mat-like member containing pulp such as cotton-like pulp or synthetic pulp. The absorbers 100, 110, and 120 may further include a super absorbent polymer (SAP). The absorbers 100, 110, 120 are provided so as to have higher rigidity than the top sheets 200, 210, 220, the leak-proof sheets 500, 510, 520 and the release sheet 300. Therefore, especially in the packaging structure 10 of the absorbent article 20 in a compressed packaging state, the shape of the absorbent bodies 100, 110, and 120 tends to affect the absorbent article 20 that is an individual package and the packaging structure 10 of the absorbent article 20. .

  The surface sheets 200, 210, and 220 are integrally joined to the peripheral portions of the leak-proof sheets 500, 510, and 520 at the peripheral portions thereof, so that the absorbent bodies 100, 110, and 120 together with the leak-proof sheets 500, 510, and 520 are obtained. Is supposed to be included. A pair of three-dimensional gathers (not shown) may be formed on the topsheets 200, 210, and 220 along both side edges in the longitudinal direction of the absorbent article 20. The three-dimensional gather is either the top sheet 200, 210, 220, the leak-proof sheet 500, 510, 520 folded back to the top sheet 200, 210, 220 side, or the three-dimensional gather sheet (not shown), or a combination thereof For example, urine can be prevented from leaking laterally at a portion formed so that a part of the body can stand up three-dimensionally.

  A pressing groove may be formed in at least one of the topsheets 200, 210, 220 and the absorbent bodies 100, 110, 120. Further, the liquid permeable surface sheets 200, 210, and 220, the absorbers 100, 110, and 120 and the liquid impermeable leak-proof sheets 500, 510, and 520 are bonded to each other at adjacent portions.
