(FR) ARTICLE ABSORBANT DE TYPE CULOTTE
(JA) パンツ型吸収性物品
Abstract
(EN) An underpants-type absorbent article (1) that comprises an absorbent body (10) and a waist line member (20) consisting of a front waistline portion (20) and a back waistline portion (30), said front waistline portion (20) and said back waistline portion (30) being annularly joined together by a pair of side joint portions (50) disposed on both sides in the horizontal direction, and that is provided with a pair of leg holes (LH). In the waistline member (20), hydrophilic regions (32, 42) are disposed on the most non-skin side of at least a part of the regions overlapping the pair of side joint portions (50) in the vertical direction. In the regions along the leg holes (LH), hydrophobic regions (13b, 31, 41), which are less hydrophilic than the hydrophilic regions (32, 42), are disposed on the most non-skin side of at least the parts located at the bottom (CL).
(FR) L'invention concerne un article absorbant de type culotte (1) qui comprend un corps absorbant (10) et un élément de taille (20) consistant en une partie de taille avant (20) et une partie de taille arrière (30), ladite partie de taille avant (20) et ladite partie de taille arrière (30) étant reliées entre elles de manière annulaire par une paire de parties de jonction latérale (50) disposées des deux côtés dans le sens horizontal, et qui est pourvu d'une paire de trous pour les jambes (LH). Dans l'élément de taille (20), des régions hydrophiles (32, 42) sont disposées sur le côté le plus éloigné de la peau d'au moins une partie des régions chevauchant la paire de parties de jonction latérale (50) dans le sens vertical. Dans les régions le long des trous pour les jambes (LH), des régions hydrophobes (13b, 31, 41), qui sont moins hydrophiles que les régions hydrophiles (32, 42), sont disposées sur le côté le plus éloigné de la peau d'au moins les parties situées au niveau du fond (CL).
(JA) 吸収性本体(10)と、左右方向の両端部に設けられた一対のサイド接合部(50)によって、前側胴回り部(20)と後側胴回り部(30)とが環状に接合された胴回り部材(20)と、を有し、一対の脚回り開口(LH)を備えたパンツ型吸収性物品(1)であって、胴回り部材(20)のうち、上下方向において、一対のサイド接合部(50)と重複する領域の少なくとも一部の最も非肌側には、親水領域(32、42)が設けられており、脚回り開口(LH)に沿った領域のうちの、少なくとも、最下端(CL)に位置する部分の最も非肌側には、親水領域(32、42)よりも親水性の低い疎水領域(13b、31、41)が設けられている。
