(JA) 吸収性物品
Abstract
(JA)

【課題】複数層の吸収体を有する吸収性物品の吸収能力,液拡散性,及び捕集能力を高める。
【解決手段】本発明の吸収性物品は,肌対向面側に位置する液透過性のトップシート10と,肌非対向面側に位置する液不透過性のバックシート20と,トップシート10とバックシート20の間に介在し厚み方向に重ねられた複数の吸収体と,を備える。複数の吸収体は,少なくとも,トップシート10側に位置する上層吸収体30と,バックシート20側に位置する下層吸収体40とを含む。上層吸収体30は,長手方向に延び所定の長さ及び幅を持つ上側開口部31を有し,下層吸収体40は,長手方向に延び上側開口部31よりも短い長さ及び幅を持つ下側開口部41を有する。上側開口部31と下側開口部41は,少なくとも部分的に厚み方向に重なっている。
