Description
前記サイド不織布は、吸収性物品の長手方向両端部において折り畳まれて前記吸収体側に接合される固定区間と、吸収性物品の長手方向中間部において前記弾性伸縮部材が接合されることによって肌側に起立する起立区間と、前記固定区間と起立区間との間において、前記弾性伸縮部材が接合されないとともに、前記吸収体側に接合されない非固定区間とを有し、前記起立区間の前側端部は前記吸収性物品を個装する際に吸収性物品の前側部分を折り畳む折り線より後側に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〜図4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、前記吸収体4の略側縁部を起立基端とし、かつ少なくとも体液排出部位Hを含むように長手方向に所定の区間内において肌側に突出して設けられた左右一対の立体ギャザーBS、BSを形成するサイド不織布7、7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。
前記サイド不織布7はそれぞれ、図1に示されるように、二重に折り畳んだ内方側部分の形態によってナプキン長手方向に所定の区間に区画されている。前記区間としては、生理用ナプキン1の長手方向両端部において、内方側部分を折り畳んで前記吸収体4側に接合した固定区間20、20と、生理用ナプキン1の長手方向中間部において、前記弾性伸縮部材12〜14がそれぞれサイド不織布7に接合され、前記弾性伸縮部材による収縮力によって肌側に起立する立体ギャザーBSを形成する起立区間21と、前記固定区間20と起立区間21との間において、前記弾性伸縮部材12〜14がサイド不織布7に接合されないとともに、前記サイド不織布7が吸収体4側に接合されない非固定区間22、22とから構成されている。なお、図1及び後段で説明する図5では、弾性伸縮部材12〜14がそれぞれ起立区間21を越えて非固定区間22及び固定区間20の中間まで延在して図示されているが、前記非固定区間22及び固定区間20の弾性伸縮部材12〜14は、弾性伸縮部材12〜14による収縮力が作用しない自然状態で延在しているものである。また、この起立区間21を越えて自然状態で延在する範囲は任意である。例えば、図示例のように、非固定区間22を越えて固定区間20の中間までとしてもよいし、非固定区間22の中間までとしてもよいし、延在させなくてもよい。
Claims (5)
- 透液性表面シートと裏面シートとの間に吸収体が介在されるとともに、肌側の両側部にそれぞれ、弾性伸縮部材による収縮力によって肌側に起立する立体ギャザーを形成するサイド不織布が設けられる吸収性物品において、
