Abstract
Description
前記透液性表面シートの少なくとも体液排出部位に対応する領域に多数の開孔が形成されるとともに、前記透液性表面シートの前記吸収体側の面に隣接して、体液排出部位に対応する領域の両側部に長手方向に沿って高吸水性樹脂が配置されたポリマーシートが備えられ、前記高吸水性樹脂が吸水して膨潤した状態で、前記高吸水性樹脂の配置領域の間であって前記透液性表面シートと前記ポリマーシートとの間に、体液保持用の空間部が形成されるようになっ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(以下、まとめて体液ともいう。)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間に介装された綿状パルプまたは合成パルプなどからなる吸収体4と、肌当接面側の両側部に長手方向に沿ってほぼ全長に亘って設けられたサイド不織布7と、前記透液性表面シート3と吸収体4との間に配設されたポリマーシート6とを備え、かつ前記吸収体4の周囲においては、その上下端縁部では前記不透液性裏面シート2と透液性表面シート3との外縁部がホットメルトなどの接着剤やヒートシール、超音波シール等の接合手段によって接合され、またその両側縁部では吸収体4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、超音波シール等の接合手段によって接合され、これら不透液性裏面シート2とサイド不織布7とによる積層シート部分によって側方に突出するウイング状フラップW、Wが形成されているとともに、これよりも臀部側に位置する部分にヒップホールド用フラップWB、WBが形成されたものである。なお、前記吸収体4の形状保持および拡散性向上のために、前記吸収体4をクレープ紙又は不織布などからなる被包シート(図示せず)で囲繞してもよい。
前記不透液性裏面シート2は、ポリエチレン等の少なくとも遮水性を有するシート材が用いられるが、蒸れ防止の観点から透湿性を有するものを用いるのが望ましい。この遮水・透湿性シート材としては、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が好適に用いられる。前記不透液性裏面シート2の非肌側面(外面)にはナプキン長手方向に沿って1または複数条の粘着剤層(図示せず)が形成され、身体への装着時に生理用ナプキン1を下着に固定するようになっている。前記不透液性裏面シート2としては、プラスチックフィルムと不織布とを積層させたポリラミ不織布を用いてもよい。
本生理用ナプキン1では、体液排泄時に、粘度が高くドロドロした経血や、固まって塊状になった経血など粘度の高い体液が表面に残るのを防止するとともに、この粘度の高い経血を保持するための空間部10が形成されるようになっている。以下、このことについて詳細に説明する。
前記透液性表面シートの少なくとも体液排出部位に対応する領域に多数の開孔が形成されるとともに、前記透液性表面シートの前記吸収体側の面に隣接して、上層不織布と下層不織布との間に、少なくとも体液排出部位に対応する領域の両側部にそれぞれ長手方向に沿って連続線状又は連続帯状に高吸水性樹脂が配置され、前記高吸水性樹脂の配置領域より外側の前記吸収体と重なる領域に前記高吸水性樹脂が介在しない非存在領域が形成されたポリマーシートが備えられ、前記高吸水性樹脂が吸水して膨潤した状態で、前記高吸水性樹脂の配置領域の間であって前記透液性表面シートと前記ポリマーシートとの間に、体液保持用の空間部が形成されるようになっていることを特徴とする吸収性物品が提供される。
