(JA) 吸収性物品
Abstract
(EN) An absorbent article (1) has an absorbent body (10) and an exterior body (30) that has a ventral waist section (30a) and a dorsal waist section (30b). The exterior body has a first hydrophobic sheet (301), a second hydrophobic sheet (302), and a hydrophilic sheet (303). At least a part of a region of the second hydrophobic sheet (302) is a region (45) having openings. When viewed in the thickness direction, if portions of the hydrophilic sheet (303) overlapping and not overlapping with the region (45) of the second hydrophobic sheet (302) having openings are defined as an overlapping section (50) and a non-overlapping section (51), respectively, the area of the overlapping section (50) is smaller than the area of the non-overlapping section (51).
(FR) Article absorbant (1) ayant un corps absorbant (10) et un corps extérieur (30) qui a une section de taille ventrale (30a) et une section de taille dorsale (30b). Le corps extérieur comporte une première feuille hydrophobe (301), une seconde feuille hydrophobe (302), et une feuille hydrophile (303). Au moins une partie d'une région de la seconde feuille hydrophobe (302) est une région (45) ayant des ouvertures. Vu dans le sens de l'épaisseur, si des parties de la feuille hydrophile (303) se chevauchant et ne se chevauchant pas avec la région (45) de la seconde feuille hydrophobe (302) ayant des ouvertures sont définies comme une section de chevauchement (50) et une section non chevauchante (51), respectivement la zone de la section de chevauchement (50), est plus petite que la zone de la section non chevauchante (51).
(JA) 吸収性本体(10)と、腹側胴回り部(30a)及び背側胴回り部(30b)を有する外装体(30)と、を有する吸収性物品(1)であって、外装体は、第1疎水性シート(301)と、第2疎水性シート(302)と、親水性シート(303)とを有し、第2疎水性シート(302)の少なくとも一部の領域は、開口を有する領域(45)であり、厚さ方向に見た場合に、親水性シート(303)のうちの、第2疎水性シート(302)の開口を有する領域(45)と重複する部分を重複部(50)とし、開口を有する領域(45)と重複しない部分を非重複部(51)としたとき、重複部(50)の面積は、非重複部(51)の面積よりも小さい。
