Description
前記高圧搾部は、前記凹溝を溝長手方向に区画した単位区間において、溝幅方向に延び溝長手方向に傾斜する傾斜要素を含むとともに、前記凹溝の一方側の側端から他方側の側端まで実質的に横断して形成され、前記単位区間の高圧搾部を溝長手方向に繰り返し正反転させたパターンで形成されている吸収性物品を提案した。
前記高圧搾部は、前記凹溝を長手方向に区画した単位区間において、溝幅方向に延び溝長手方向に傾斜するとともに、前記凹溝の一方側の側端から他方側の側端まで横断して形成され、この単位区間を溝長手方向に繰り返し正反転させたパターンで形成された第1エンボスと、前記第1エンボスが幅方向外側に突出する凸部と反対側の側縁部に、前記凹溝に沿って形成された第2エンボスとから構成され、
前記第1エンボスと第2エンボスとが離間して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。
本発明に係る失禁パッド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、尿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、必要に応じて前記透液性表面シート3と吸収体4との間に配置される親水性のセカンドシート6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とから主に構成され、かつ前記吸収体4の周囲においては、その長手方向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。前記吸収体4は、形状保持および拡散性向上のために、図示しないクレープ紙や不織布等の被包シートによって囲繞することができる。
前記不透液性裏面シート2は、ポリエチレン、ポリプロピ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、この他に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好適に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。
本失禁パッド1では、表面側(肌面側)に長手方向に沿って体液流入用の凹溝22が形成されている。前記凹溝22は、透液性表面シート3の表面に排出された体液を受け止めて、体液を一時貯留するとともに、前後方向に体液の拡散を誘導し、且つ吸収体4への体液の吸収速度を速め、横漏れを防止するためのものである。
以下、前記高圧搾部23について説明する。前記高圧搾部23は、周辺の凹溝22の底面より更に深く圧搾された部分であり、凹溝22の底面に所定のパターンで形成されている。具体的に、前記高圧搾部23は、図5に示されるように、平面視で、凹溝22を長手方向に区画した単位区間26において、溝幅方向に延び溝長手方向に傾斜するとともに、前記凹溝22の一方側の側端から他方側の側端まで横断して形成され、この単位区間26を溝長手方向に繰り返し正反転させた、全体として前記凹溝22に沿うとともに、前記凹溝22の両側縁を往復するように幅方向両側に凹凸を繰り返すパターンで形成された波状の第1エンボス24と、前記波状の第1エンボス24が幅方向外側に突出する凸部24a、24bと対向する反対側の前記凹溝22の側縁部に、前記凹溝22に沿って形成された第2エンボス25とから構成されている。
(1)上記形態例では、前記高圧搾部23は、透液性表面シート3の表面側からの圧搾により透液性表面シート3から吸収体4にかけての構成部材に一体的に付与していたが、吸収体4の表面側からの圧搾により吸収体4のみに付与するか、又は被包シートの表面側からの圧搾により被包シート及び吸収体4に一体的に付与したものでもよい。少なくとも吸収体4に前記高圧搾部23を設けておけば、装着時の凹溝の変形が防止できるとともに、溝長手方向に沿って体液が拡散しやすくなる。
(2)前記波状の第1エンボス24は、前記凹溝22を長手方向に区画した単位区間26において、溝幅方向に延び溝長手方向に傾斜するとともに、前記凹溝22の一方側の側端から他方側の側端まで横断して形成され、この単位区間26を溝長手方向に繰り返し正反転させたパターンで形成されていれば、図8に示されるように、幅方向外側に突出する凸部24a、24bが三角形状に形成されたものや、台形状、四角形状に形成されたものでもよい。
(3)前記第2エンボス25は、凹溝22に沿って形成してあれば、図9に示されるように、平面形状が(A)半円形や(B)三角形などの図形パターンで形成してもよい。また、図9(A)に示されるように、波状の第1エンボス24を曲線で形成した場合、この曲線に合わせて前記第2エンボス25はエンボスの外形線が曲線となる半円形パターンで形成するのが好ましく、同図9(B)に示されるように、波状の第1エンボス24を直線のジグザグ線で形成した場合、このジグザグ線に合わせて前記第2エンボス25はエンボスの外形線が直線となる三角形パターンで形成するのが好ましい。
