Description
前記吸収性物品の少なくとも後方中央部分に、前記吸収性物品の長手方向に延びるとともに、肌当接面側に隆起する吸収体中高部を有し、かつ前記吸収体中高部に対応する吸収体の非肌当接面側に前記吸収性物品の長手方向に沿って断続的な凹状溝が形成されているとともに、前記断続的な凹状溝は、所定間隔で列を成すように配置された、三角形の頂部を吸収性物品前端側に向けて配向された三角形溝、クサビ尖鋭部を吸収性物品前端側に向けて配向されたクサビ形状溝、頂部を吸収性物品前端側に向けて配向された菱形形状溝のいずれかであ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〕
図1は本発明の第1形態例に係る生理用ナプキン1の展開図であり、図2は図1のII−II線矢視図、図3は図1のIII−III線矢視図である。
前記不透液性バックシート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、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。前記不透液性バックシート2の非使用面側(外面)には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。前記不透液性バックシート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。
《肌当接面側に形成されるエンボス》
従来の吸収性物品の場合、肌当接面側に形成される吸収体の隆起形状は単一の弧状曲線からなる単純な形状とされるものが一般的であったが、実際には女性の排血部位の形状は複雑で、女性の排血口付近に吸収体をほぼ密着させることができたとしても、膣口から後方側の肛門付近にかけての会陰部が小さな窪み状の立体形状を成しているため、この会陰部に対して吸収体を密着できていない。そのため、排血口付近で吸収できなかった経血等が前記会陰部でも吸収されず、後漏れの原因となることがあった。
本生理用ナプキン1においては、図4及び図6に示されるように、前記吸収体中高部6の後方側部分に対応する吸収体4の非肌当接面側部分に対し、前記生理用ナプキン1の長手方向に沿って断続的な凹状溝14、14…が形成されている。すなわち、本生理用ナプキン1では、凹状溝を連続的に形成するのではなく、比較的短い直線状の凹状エンボスと、エンボス無加工部分とが交互に列を成すような断続的な凹状溝14、14…を形成することにより、前記凹状溝14,14…に沿う軸Yを可撓軸とする横断方向の変形性能を確保すると同時に、図6に示されるように、前記凹状溝14,14の間のエンボス無加工部分を通る多数の横断軸XK、XK…を可撓軸とするナプキン長手方向の変形性能を確保するものである。
Claims (3)
- 透液性トップシートとバックシートとの間に吸収体が介在された吸収性物品において、
前記吸収性物品の少なくとも後方中央部分に、前記吸収性物品の長手方向に延びるとともに、肌当接面側に隆起する吸収体中高部を有し、かつ前記吸収体中高部に対応する吸収体の非肌当接面側に前記吸収性物品の長手方向に沿って断続的な凹状溝が形成されているとともに、前記断続的な凹状溝は、所定間隔で列を成すように配置された、三角形の頂部を吸収性物品前端側に向けて配向された三角形溝、クサビ尖鋭部を吸収性物品前端側に向けて配向されたクサビ形状溝、頂部を吸収性物品前端側に向けて配向された菱形形状溝のいずれかであることを特徴とする吸収性物品。 - 前記吸収体の非肌当接面側において、前記凹状溝の後方端部から連続して或いはその近傍点より、吸収性物品の後方側に向けて漸次両者の離間幅を拡大させる2条の凹状溝を形成してある請求項1記載の吸収性物品。
- 前記吸収体の非肌当接面側において、前記断続的な凹状溝を会陰部対応部位まで延長させるとともに、前記凹状溝の前方端近傍部位に近接して円形の凹状溝を形成してある請求項1〜2いずれかに記載の吸収性物品。
