Abstract
(EN)
Provided is an absorbent article in which the occurrence of wrinkles can be suppressed and the degradation of fitting property and absorption performance can be suppressed. This absorbent article is provided with an absorbent main body (10) including an abdomen-side section (2), a backside section (3), and an absorbent body (14). The absorbent body has a squeeze section (71) that includes a highly absorbent polymer and extends in the longitudinal direction. The absorbent main body includes, on both sides in the width direction, one pair of side sheets (17, 17) extending in the longitudinal direction. The side sheets each have: fixed regions (15, 15) that are positioned on an end section on the front side and rear side in the longitudinal direction and fixed to a surface of the absorbent main body; and a leak preventing wall (16) which includes an elastic member (61) extending in the longitudinal direction, is positioned between the fixed regions on the front side and the rear side, fixes the outer end edge in the width direction to the surface of the absorbent main body, and does not fix the inner end edge in the width direction. In the longitudinal direction, an end edge (71e) on the front side of the squeeze section is positioned closer to the front side in the leak preventing wall than the front end edge, and an end edge (71e) on the rear side of the squeeze section is positioned closer to the rear side in the leak preventing wall than the rear end edge.

L'invention concerne un article absorbant dans lequel l'apparition de plis peut être supprimée et la dégradation de la propriété d'ajustement et de la performance d'absorption peut être supprimée. Cet article absorbant est pourvu d'un corps principal absorbant (10) comprenant une section côté abdomen (2), une section arrière (3), et un corps absorbant (14). Le corps absorbant a une section de compression (71) qui comprend un polymère hautement absorbant et s'étend dans la direction longitudinale. Le corps principal absorbant comprend, des deux côtés dans le sens de la largeur, une paire de feuilles latérales (17, 17) s'étendant dans la direction longitudinale. Les feuilles latérales ont chacune : des régions fixes (15, 15) qui sont positionnées sur une section d'extrémité sur le côté avant et le côté arrière dans la direction longitudinale et fixées à une surface du corps principal absorbant; et une paroi de prévention de fuite (16) qui comprend un élément élastique (61) s'étendant dans la direction longitudinale, est positionnée entre les régions fixes sur le côté avant et le côté arrière, fixe le bord d'extrémité externe dans la direction de la largeur à la surface du corps principal absorbant, et ne fixe pas le bord d'extrémité interne dans la direction de la largeur. Dans la direction longitudinale, un bord d'extrémité (71e) sur le côté avant de la section de compression est positionné plus près du côté avant dans la paroi de prévention de fuite que le bord d'extrémité avant, et un bord d'extrémité (71e) sur le côté arrière de la section de compression est positionné plus près du côté arrière dans la paroi de prévention de fuite que le bord d'extrémité arrière.
