Abstract
Description
まず、吸収性物品の基本構造について、生理用ナプキンを例として説明する。図1に、本発明の一形態による吸収性物品1の平面図を示す。また、図2に、吸収性物品1のI−I線断面図を示す。図1及び図2に示すように、吸収性物品1は、不透液性の裏面シート2、吸収体4、透液性の表面シート3がこの順に積層されて構成され、全体として扁平形状を有する。吸収性物品1の装着時には、表面シート3側が肌に触れる側(肌側若しくは表側)となり、裏面シート2側が下着に固定される側(下着側若しくは裏側)となる。
吸収性物品1には、薬剤が塗布された薬剤塗布部Aが設けられていてよい。薬剤塗布部Aは、薬剤が実際に塗布された部分、及び塗布された部分から薬剤が浸透・拡散した結果、薬剤が存在する部分も含む。薬剤塗布部Aは、吸収性物品1の露出面以外の場所に設けられていてよい。本明細書において、吸収性物品1の露出面とは、吸収性物品1広げた状態で外部に露出する面であり、吸収性物品1の肌面側及び非肌面側の面を含む。例えば、薬剤塗布部Aは、表面シート3の肌面(表面)及び裏面シート2の非肌面(裏面)以外の場所に設けられていることが好ましい。薬剤塗布部Aが、吸収性物品1の肌面側(表面側)の露出面にないことが好ましいのは、薬剤が肌に直接接触することを回避するためであり、吸収性物品1の非肌面側(裏面側)の露出面にないことが好ましいのは、薬剤が装着時に下着に接触することを回避し、多くの形態において裏面シート2の非肌面に設けられている粘着部の機能を阻害しないためである。
図1及び図2に示すように、吸収性物品1には圧搾部10が設けられていてよい。圧搾部10は、肌面側(表面シート3側)から非肌面側(裏面シート2側)へと部分的に圧力をかけて高密度化する加工(エンボス加工)が施された部分(フィットエンボスという場合がある)である。圧搾部10は、吸収体4及び表面シート3を積層させてなる積層体、又は吸収体4、セカンドシート、及び表面シート3を積層させてなる積層体を、肌面側から圧搾することによって形成できる。例えば、上記のような積層体を、一対の加圧ロールの間に通過させることによって形成できる。その場合、積層体の肌面側に凸状のロールを、非肌面側に平坦なロールが配置されるようにする。
図3に、本発明の変形例を示す。図3に示された吸収性物品1は、図1に示された吸収性物品1と基本的な構造は同じであるが、圧搾部10の形状が異なる。図3の例においても、体液排出口対応領域Qの中心QCと薬剤塗布部Aとを結ぶ任意の直線上に、薬剤塗布部Aから離間して形成された塞き止め圧搾部11が形成されているが、塞き止め圧搾部11を含む圧搾溝10が、中間領域Mに形成された前後方向D1に沿って延びる一対の前後方向圧搾部と離間している。
図8に、図1に示す吸収性物品1で使用される吸収体4の平面図を示す。図8に示す吸収体4は、表面シート3が積層される前の状態、すなわち吸収体4と表面シート3との積層体が圧搾されて圧搾部10が形成される前の状態にある。図8に示すように、吸収体4自体にも圧搾部20が形成されている。
図11に、図1に示す吸収性物品1が、包装シート50とともに折り畳まれて包装されて得られた包装吸収性物品100を示す。吸収性物品1を包装シート50で包装する場合、図1に示すように、吸収性物品1を包装シート50に載置し、包装シート50及び吸収性物品1をともに、表面シート3側(肌面側)に前後方向D1に折り畳む。後方領域Rを第1折り線L1で折り返した後、前方領域Fを第2折り線L2にて、後方領域Rに重ねるように折り返す。なお、ウィングWG、WGは、上記の前後方向D1の折り畳みの前に、表面シート3側へ折り返しておくことが好ましい。
