Abstract
Description
第1手段は、液透過性の表面シートと、液不透過性の裏面シートと、前記表面シートと裏面シートの間に設けられた吸収体と、前記裏面シートの外面に外装シートと、前記外装シートの前後方向の両端部に係止部材を設けたパッドにおいて、
前記吸収体を、前身部と、後身部と、前記前身部と後身部に幅方向の寸法を小さくした括れ部で形成し、前記吸収体の幅方向の中央部に前後方向に延在する第1溝を形成し、前記括れ部における前後方向の中央部に幅方向に延在する第3溝を形成し、前記括れ部における前後方向の前側部に幅方向に延在する第2溝を形成し、前記括れ部における前後方向の後側部に幅方向に延在する第4溝を形成したことを特徴とする。
中央部に括れ部12Dが形成されている。本明細書では、便宜的に、装着者の前身頃に対応する吸収体12における括れ部12Dよりも長手方向の前側部分を前身部12Cと言い、装着者の後身頃に対応する吸収体12における括れ部12Dよりも長手方向の後側部分を後身部12Eと言う。
次に、第1実施形態のパッドについて説明する。図7に示すように、第1実施形態のパッドは、吸収体12の内側吸収体12Aの内面側に断面視において略凹形状の溝20を形成している。溝20は、内側吸収体12Aの幅方向の中央部に前後方向に延在する第1溝21と、括れ部12Dの最狭幅部の前後方向の前側部に幅方向に延在する第2溝22と、括れ部12Dの最狭幅部の前後方向の中央部に幅方向に延在する第3溝23と、括れ部12Dの最狭幅部の前後方向の後側部に幅方向に延在する第4溝24から形成されている。
次に、第2実施形態のパッドについて説明する。なお、第1実施形態のパッドと同一部品には同一符号を付して説明を省略する。図11に示すように、第2溝22は、第1溝21から内側吸収体12Aの幅方向の左端部に延在する第2左側溝22Aと、第1溝21から内側吸収体12Aの幅方向の右端部に延在する第2右側溝22Bで形成され、第4溝24は、第1溝21から内側吸収体12Aの幅方向の左端部に延在する第4左側溝24Aと、第1溝21から内側吸収体12Aの幅方向の右端部に延在する第4右側溝24Bで形成されている。
