Abstract
【構成】上面及び下面と、透液性のトップシート11と、不液性のバックシート12と、トップシート11とバックシート12との間に介在し、分離する高吸収性ポリマー粒子17を有する吸収層13と、上面から下面へ向かって延びる圧搾条溝14とを含む使い捨ての体液吸収性物品10において、吸収層13の配置された領域が、高吸収性ポリマー粒子17の存在する分布域24,25と、前記高吸収性ポリマー粒子17の存在しない非分布域23とに区分されており、圧搾条溝14が非分布域23に形成され、非分布域23が圧搾条溝の周縁部から外方へ延在している。
【選択図】図1
Description
(1)前記圧搾条溝が、前記物品の中央部を囲む連続的または非連続的な略環状の溝から形成され、前記非分布域が前記圧搾条溝の形状に沿うような略環状を有してその周縁部から外方へ延在しており、前記分布域が、前記非分布域に囲まれて、その内側に位置する内側分布域と、前記非分布域の外方に位置する外側分布域とに区分されている。
(2)前記吸収層が、透液性の上部シートと、透液性の下部シートと、前記上下部シート間に分布する前記高吸収性ポリマー粒子とから形成され、前記上下部シートの向かい合う内面どうしが接合手段によって接合されている。
(3)前記接合手段が、ホットメルト接着剤であって、前記上下部シートの前後端部と両側縁部とには、高吸収性ポリマーが分布しておらず、前記高吸収性ポリマー粒子が体液を吸収して膨潤することによって、前記前後端部及び前記両側縁部を除き、前記内側分布域と前記外側分布域における前記接合手段の接合が解除される。
(4)前記吸収層と前記バックシートとの間に、高吸収性のポリマー粒子と親水性繊維とを混合して形成された保液層が配置されている。
(5)前記圧搾条溝が、前記トップシートの上面から前記保液層まで延びている。
