Abstract
Description
前記上層シートは、肌側に膨出する前記高吸水性ポリマー充填用の空間部を形成する突出部が複数設けられるとともに、前記突出部の周縁に周方向に沿って間欠的に前記上層シートと下層シートとが接合された接合部が設けられていることを特徴とする吸収性物品が提供される。
本発明に係る生理用ナプキン1は、図1及び図2に示されるように、ポリエチレンシート、ポリプロピレンシートなどからなる不透液性裏面シート2と、経血やおりものなどを速やかに透過させる透液性表面シート3と、これら両シート2,3間に介在された2層のシート間に高吸水性ポリマーが配置された構造からなる吸収体4と、表面両側部にそれぞれ長手方向に沿って配設されたサイド不織布7,7とから構成されている。また、前記吸収体4の周囲において、そのナプキン長手方向の前後端縁部では、前記不透液性裏面シート2、透液性表面シート3の外縁部がホットメルトなどの接着剤やヒートシール等の接着手段によって接合され、またその両側縁部では吸収体4の側縁よりも側方に延出している前記不透液性裏面シート2と前記サイド不織布7とがホットメルトなどの接着剤やヒートシール等の接着手段によって接合され、外周に吸収体4の存在しない外周フラップ部が形成されている。
前記不透液性裏面シート2は、ポリエチレンやポリプロピレン等のオレフィン系樹脂シートなどの少なくとも遮水性を有するシート材が用いられるが、この他にポリエチレンシート等に不織布を積層したラミネート不織布や、さらには防水フィルムを介在して実質的に不透液性を確保した上で不織布シート(この場合には防水フィルムと不織布とで不透液性裏面シートを構成する。)などを用いることができる。近年はムレ防止の観点から透湿性を有するものが用いられる傾向にある。この遮水・透湿性シート材は、ポリエチレンやポリプロピレン等のオレフィン系樹脂中に無機充填剤を溶融混練してシートを成形した後、一軸または二軸方向に延伸することにより得られる微多孔性シートである。
以下、前記吸収体4について詳細に説明する。前記吸収体4は、図3〜図5に示されるように、肌側(透液性表面シート3側)に配置された上層シート10と非肌側(不透液性裏面シート2側)に配置された下層シート11との間に高吸水性ポリマー12が配置された構造を有している。
上記形態例では、第1突出部と第2突出部とからなる2種類の突出部が設けられた例を図示していたが(図9)、3種類以上の突出部を設けてもよい。
前記上層シートは、肌側に膨出する前記高吸水性ポリマー充填用の空間部を形成する突出部が複数設けられるとともに、前記突出部の周縁に周方向に沿って間欠的に前記上層シートと下層シートとが接合された接合部が設けられ、隣り合う前記接合部同士の周方向に沿う離間距離は、未吸水時の前記高吸水性ポリマーの平均粒径より大きく、前記平均粒径の3倍より小さいことを特徴とする吸収性物品が提供される。
