Description

  The present invention relates to an absorbent article to be attached to a region including a wearer's crotch.

  In many cases, pulp and absorbent polymer are used for the absorbent core provided in the absorbent article. For this reason, when absorbing excretory fluids, such as urine, an absorption core tends to expand greatly by swelling of an absorption polymer. Here, when the absorbent polymer expands, air is often involved between the absorbent polymers to form bubbles or gaps, and the absorbent polymer tends to expand beyond the amount of liquid absorbed.

  FIG. 7 is a diagram schematically showing a configuration of a cross-sectional view of a conventional absorbent article. As shown in FIG. 7, the conventional absorbent article 1 has an outer sheet member 3 and an inner sheet member 4 disposed on the outer surface side and the skin surface side of the absorbent core 2. While the outer sheet member 3 is often configured to include a waterproof resin film, the inner sheet member 4 is often configured mainly using a non-woven fabric. The member 4 tends to be easily extended. For this reason, when the absorption core 2 expand | swells by absorption of excretion liquid, as shown in FIG. 8, the tendency for the absorption core 2 to expand | swell toward the inner sheet | seat member 4 side which is easier to expand is strong. Thus, when the absorption core 2 expand | swells to the skin surface side, the clearance gap 6 may arise between a wearer's buttocks 5 and the absorbent article 1. FIG. Such a gap 6 may induce leakage of urine when the next urination is performed.

  Moreover, as shown in FIG. 9, when the left and right three-dimensional gathers 7 are provided in the absorbent article 1, the three-dimensional gathers of the inner sheet member 4 are caused by the expansion of the absorbent core 2 toward the skin surface as described above. The difference between the height of the sheet surface 4a on the inner side in the horizontal direction 7 and the height of the three-dimensional gather 7 is reduced. Accordingly, the side leakage preventing effect is impaired by the three-dimensional gather 7, and excrement such as urine may leak out of the absorbent article 1 so as to get over the three-dimensional gather 7.

  In addition, as a prior art document, there exists what provided the tack | tuck in the waist gather part of the absorbent article (patent document 1).
