Description
ナプキン本体の縦方向中心線に沿って位置する第1の隆起部と、前記縦方向中心線から横方向の両側に離れて位置する第2の隆起部とが設けられ、前記第1の隆起部と前記第2の隆起部は、それぞれ縦方向に間隔を空けて位置する前方起端と後方起端とを有し、
前記第1の隆起部および第2の隆起部は、それぞれナプキン本体の肌側表面から立ち上がるシートと、前方起端と後方起端との間で前記縦方向に弾性収縮力を発揮してナプキン本体を肌側表面が窪むように変形させるとともに前記シートをナプキン本体の肌側表面から隆起させる弾性部材とを有しており、
前記第2の隆起部が前記第1の隆起部よりも前方に位置して、前記第1の隆起部と前記第2の隆起部とが横方向に重なる重複領域が設けられ、前記第1の隆起部における前記前方起端と後方起端との中間点が、前記第2の隆起部における前方起端と後方起端との中間点よりも後方に位置しており、
前記重複領域の前方において第2の隆起部が設けられている領域を前方領域、前記重複領域の後方において第1の隆起部が設けられている領域を後方領域としたときに、隆起部がナプキン本体に与える曲げ応力は、前方領域よりも重複領域の方が大きく、且つ後方領域よりも重複領域の方が大きいことを特徴とするものである。
図7は本発明の第2の実施の形態の生理用ナプキン101を示すものであり、図4に相当する断面図である。
この生理用ナプキン301のナプキン本体202は、前記図8に示した第3の実施の形態と同じものである。この実施の形態の第1の表面構成要素303においても、前方起端34と後方起端35との間の少なくとも一部において、第1の隆起部331がナプキン本体202の肌側表面から離れて自由に動けるようになっている。
この生理用ナプキン401では、ナプキン本体2の構造が第1の実施の形態と同じである。第1の表面構成要素403で形成される第1の隆起部431は、表面シート23によって、断面がT字形状となるように形成されている。
その他、第2の隆起部の立体形状はどのようなものであってもよい。
