Description
前記吸収性物品は、尿量20cc以上を吸収する中量用以上の失禁パッドであり、
前記表面シートは、綿繊維100重量%からなるスパンレース不織布の少なくとも排泄口対応部分に撥水剤が塗布されてなるとともに、肌対向面側に、平面視で、所定の傾斜角度方向に沿うとともに、吸収性物品の長手方向に一定間隔で形成された多数の第1の凹部線と、前記第1の凹部線を吸収性物品の長手方向線で幅方向に反転させた傾斜角度方向に沿うとともに、吸収性物品の長手方向に一定間隔で形成された多数の第2の凹部線とにより菱形格子状パターンの凹部線が形成されるとともに、これら凹部線によって区画された菱形格子形状の画成領域が吸収性物品の長手方向及び幅方向に隣接配置され、少なくとも排泄口対応部分に表裏を貫通する多数の開孔が形成され、
前記菱形格子形状の画成領域の長手方向寸法S1及び幅方向寸法S2は、5〜20mmとされるとともに、前記幅方向寸法S2>長手方向寸法S1とし幅方向に長い菱形形状とされており、
前記表面シートの前記吸収体側に熱可塑性繊維からなるセカンドシートが接着されるとともに、前記表面シートとセカンドシートとが前記第1の凹部線及び第2の凹部線において前記セカンドシートの熱融着により接合され、前記凹部線の目付と前記画成領域との目付がほぼ同等に形成され、かつ前記凹部線の密度が前記画成領域の密度より高く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。
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、肌当接面をなし、尿などを速やかに透過させる表面シート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、吸収体4の略側縁部を起立基端とし、かつ少なくとも着用者の排尿口部Hを含むように前後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とから主に構成され、かつ吸収体4の周囲においては、その上下端縁部では不透液性裏面シート2と表面シート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不透液性裏面シート2と、立体ギャザーBSを形成しているサイド不織布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。図示例においては、吸収体4は1層構造となっているが、中高部を形成する多層構造としてもよく、また、同一の大きさ、形状の吸収体を重ねた多層構造としてもよい。
前記表面シート3は、吸収体4の肌側を覆う部分である肌当接面を形成するものであり、綿繊維100重量%からなるスパンレース不織布で構成されるのが特徴である。スパンレース不織布は、接着剤を使用しない、柔軟性を有する等の利点を有する。
前記吸収体4は、尿を吸収・保持し得るものであり、フラッフ状のパルプ繊維中に粉粒状の高吸水性ポリマーを分散混入したものが使用される。前記吸収体4は、パルプ繊維及び高吸水性ポリマーのみからなり、合成繊維が含まれていない。
前記表面シート3が多数の開孔10を有する場合、前記開孔10から吸収体4を構成するパルプ、ポリマー、接着剤等が露出するのを防ぐため、表面シート3と吸収体4との間に中間シート6を配することが好ましい。前記中間シート6は、吸収体4からの逆戻り防止、クッション様効果により着用時の肌触りを柔らかくする効果も有する。但し、前記表面シート3に開孔が設けられない部分には、前記中間シート6は配置してもよいし、配置しなくてもよい。また、図5に示される表面シート3の場合、吸収体4側の面にセカンドシート23が積層されているため、更に中間シート6を設けなくてもよい。
