Abstract
Description
前記圧搾溝は、少なくとも体液排出部に対応する部位を含む領域から臀部溝に対応する部位を含む領域にかけての両側部にそれぞれ形成され、
前記圧搾溝は、着用者の体液排出部に対応する部位の後方に、左右の離間幅を狭めた離間幅縮小領域が形成されるとともに、前記離間幅縮小領域内であって左右の圧搾溝の離間幅が最小となる部分に、前記圧搾溝の溝幅を急激に拡大させた急拡大部が形成され、前記急拡大部は前記圧搾溝の両方の側壁が外側に膨出して形成され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〜図3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ることにより、吸収体が介在しないフラップ部が形成されたものである。なお、図示例では、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5で囲繞しているが、この被包シート5は設けなくてもよい。また、図示しないが、前記透液性表面シート3の非肌側に隣接して、前記透液性表面シート3とほぼ同形状の親水性の不織布などからなるセカンドシートを配設してもよい。
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、前記中高部6の近傍外側部位置に、肌当接面側(透液性表面シート3の外面側)から非肌側(不透液性裏面シート2側)に向けて窪ませた圧搾溝8が形成されている。前記圧搾溝8は、少なくとも体液排出部Hに対応する部位を含む領域から臀部溝に対応する部位を含む領域にかけての両側部にそれぞれ形成されている。体液排出部Hに対応する部位を含む領域とは、生理用ナプキン1の装着時に着用者の体液排出部Hが当接する部位を全て含む幅方向中央領域であり、そのナプキン長手方向の範囲は、両側にウイング状フラップWが備えられたものでは、概ねこのウイング状フラップWの長手範囲に相当する。また、臀部溝に対応する部位を含む領域とは、生理用ナプキン1の装着時に着用者の臀部溝の少なくとも一部を含む幅方向中央領域であり、股下側の臀部溝の開始位置から後方に臀部溝の中間位置までの範囲である。
次に、第2形態例に係る生理用ナプキン1について、図8及び図9に基づいて説明する。第2形態例に係る生理用ナプキン1では、急拡大部10の形状及び透液性表面シート3の面側に形成される圧搾溝のパターンが異なっている。
Claims (3)
- 透液性表面シートと不透液性裏面シートとの間に吸収体が介在されるとともに、前記透液性表面シートの面側に略長手方向に沿う左右対の圧搾溝が形成された吸収性物品において、
