Title
(EN) ABSORBENT ARTICLE
(FR) ARTICLE ABSORBANT
(JA) 吸収性物品
Abstract
(EN) An absorbent article is provided which feels better against the skin and which can prevent the leakage of bodily fluid from the ends in the width direction, that is, can prevent side leakage, even for large amounts of bodily fluid. In this absorbent article (1), in the width direction, the length of an auxiliary sheet (5) positioned between a surface sheet (2) and an absorbent body (4) is greater than the length of the surface sheet, and the ends of the auxiliary sheet extend to outside of the ends of the surface sheet. The surface sheet includes a central area (CA) which is positioned in the center part in the width direction, and a pair of end areas (EA) which are positioned at the two ends in the width direction and which are adjacent to the outside of the central area on both sides in the width direction. The length in the thickness direction of each of the pair of end areas is greater than the length in the thickness direction of the central area.
(FR) L'invention concerne un article absorbant qui a un toucher amélioré contre la peau et qui peut empêcher la fuite de fluide corporel depuis les extrémités dans le sens de la largeur, c'est-à-dire une fuite latérale, même pour de grandes quantités de fluide corporel. Dans cet article absorbant (1), dans le sens de la largeur, la longueur d'une feuille auxiliaire (5) positionnée entre une feuille de surface (2) et un corps absorbant (4) est supérieure à la longueur de la feuille de surface, et les extrémités de la feuille auxiliaire s'étendent vers l'extérieur des extrémités de la feuille de surface. La feuille de surface comprend une zone centrale (CA) qui est positionnée dans la partie centrale dans la direction de la largeur, et une paire de zones terminales (EA) qui sont positionnées aux deux extrémités dans la direction de la largeur et qui sont adjacentes à l'extérieur de la zone centrale sur les deux côtés dans la direction de la largeur. La longueur dans la direction de l'épaisseur de chacune de la paire de zones terminales est supérieure à la longueur dans la direction de l'épaisseur de la zone centrale.
(JA) 体液の量が多い場合でも、体液の幅方向の端部からの漏れ、すなわち、横漏れを抑制しつつ、肌触りも改善し得る吸収性物品を提供する。吸収性物品(1)では、幅方向において、表面シート(2)と吸収体(4)との間に位置する補助シート(5)の長さは表面シートの長さよりも大きく、補助シートの両端部の各々は表面シートの両端縁の各々の外側に延出している。表面シートは、幅方向の中央部に位置する中央領域(CA)と、幅方向の両端部に位置し、中央領域の幅方向の両外側に隣接する一対の端部領域(EA)と、を含んでいる。一対の端部領域の各々における厚さ方向の長さは、中央領域の厚さ方向の長さよりも大きい。
