Description
前記本体部分の不透液性裏面シート側の面に本体ズレ止め粘着剤層が形成されるとともに、前記ウイング状フラップの不透液性裏面シート側の面にウイングズレ止め粘着剤層が形成され、
個装材によって個装した製品状態において、前記本体ズレ止め粘着剤層が本体用剥離材によって覆われ、前記ウイング状フラップに形成されたズレ止め粘着剤層が幅方向に横断するウイング用剥離材によって覆われ、
前記ウイング状フラップが透液性表面シート側に前記ウイング用剥離材と共に折り畳まれるとともに、個装材が少なくとも前記ウイング用剥離材と固着され、かつ前記ウイング状フラップを折り畳んだ折り畳み線の両端の内、開封に当たり前記個装材の剥離が最初に行われる側の端部を前端位置とし、
前記透液性表面シート側において前記ウイング状フラップの先端部が重なるとともに、該重なり部分でウイング状フラップ同士がウイング仮止め粘着剤層によって直接的に又は前記ウイング用剥離材を間に介して間接的に剥離可能に接合され、
前記ウイング用剥離材と前記個装材との固着は、前記ウイング状フラップの折り畳み線の前端位置を前後方向に跨がるように形成された第1固着領域によって固着され、前記ウイングズレ止め粘着剤層は、前記ウイング状フラップの後側に偏倚して形成されるとともに、前記折り畳み線の前端位置から後側に30mm以上の離間幅を設けて形成されていることを特徴とする吸収性物品が提供される。
(生理用ナプキン1の基本構造)
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、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間に介在された綿状パルプまたは合成パルプなどからなる吸収体4と、この吸収体4の形状保持および拡散性向上のために前記吸収体4を囲繞するクレープ紙5と、表面両側部にそれぞれ長手方向に沿って形成されたサイド不織布6,6とから構成されている。前記吸収体4の周囲において、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6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ている。本明細書では、この両側縁部のフラップ部分を「側部外周フラップFS」という。
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。
次に、個装シート16と本体用剥離材11及びウイング用剥離材12との固着領域について説明する。
Claims (5)
- 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た本体部分の両側部に夫々、装着時に下着のクロッチ部分を巻き込むようにして固定されるウイング状フラップが形成された吸収性物品において、
