Abstract
【解決手段】排血口対応部Mに対して、長手中心線CLの両側にそれぞれ、ナプキン1の略長手方向に沿う部分を有する排血口対応エンボス10を形成するとともに、排血口対応エンボス10より後側に離隔して、長手中心線CLの両側にそれぞれ幅方向外側に曲率中心を有する円弧状の臀部潰れ対応エンボス13、13と、長手中心線CL上の位置から後側に向けて両側に漸次拡大する略逆V字形状部分を有する臀部溝対応エンボス12とを形成する。前記臀部潰れ対応エンボス13は、その後側部分が前記臀部溝対応エンボス12の前側部分と所定区間で重なり、該重なり区間において臀部溝対応エンボス12の外側に離隔して設けられ、その後端部分がそれぞれ長手中心線CLを境に同じ側に形成される臀部溝対応エンボス12の逆V字形状部分とほぼ平行して形成する。
【選択図】図1
Description
装着時に着用者の排血口部及び会陰部に対応する排血口対応部に対して、長手方向中心線の両側にそれぞれ、吸収性物品の略長手方向に沿う部分を有する排血口対応エンボスを形成するとともに、前記排血口対応エンボスより吸収性物品の長手方向後側に離隔して、長手方向中心線の両側にそれぞれ吸収性物品の幅方向外側に曲率中心を有する円弧状の臀部潰れ対応エンボスと、長手方向中心線上の位置から後側に向けて両側に漸次拡大する略逆V字形状部分を有する臀部溝対応エンボスとを形成し、
前記臀部潰れ対応エンボスは、その後側部分が前記臀部溝対応エンボスの前側部分と長手方向に沿った所定区間で重なり代を有するとともに、該重なり代区間において前記臀部溝対応エンボスの外側に離隔して設けられ、且つその後端部分がそれぞれ長手方向中心線を境に同じ側に形成される前記臀部溝対応エンボスの逆V字形状部分とほぼ平行するように形成してあることを特徴とする吸収性物品が提供される。
(第1形態例)
本発明の第1形態例に係る生理用ナプキン1は、図1に示されるように、主に就寝時の仰向き寝及び横向き寝において臀部に好適にフィットするようにしたものである。
前記裏面シート2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シートなどの少なくとも遮水性を有するシート材が用いられるが、この他にポリエチレンシート等に不織布を積層したラミネート不織布や、さらには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用いられる傾向にある。この遮水・透湿性シート材は、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である。
エンボス構造について説明する前に、図2に基づいて、就寝時の女性の股下周辺に生理用ナプキン1をフィットさせるのにポイントとなる領域について説明する。このポイントとなる領域は、身体前側の恥骨周辺の前側領域S1、排血口対応部R1及び会陰部R2を含む中央領域S2、臀部の谷間が形成される臀部溝領域S3に加え、就寝時の仰向け寝及び横向き寝に臀部の肉が潰れ、この潰れた臀部の肉が股下を通じて排血口側にはみ出るように寄せられ、前記臀部溝領域S3と中央領域S2との間の両側に丸みを帯びて膨出する臀部潰れ領域S4、S4がある。本生理用ナプキン1は、この身体の各領域S1〜S4に好適にフィットするようにしたものである。
次に、第2形態例に係る生理用ナプキン1Aについて、図4及び図5に基づいて説明する。本生理用ナプキン1Aは、主に経血量が少ないときの就寝時や昼間などに使用するためのものである。なお、以下に説明する第2形態例に係る生理用ナプキン1Aのエンボス構造は、上記第1形態例に係る生理用ナプキン1にも適宜採用することができる。
Claims (8)
- 透液性の表面シートと不透液性の裏面シートとの間に吸収要素が介在された吸収性物品において、
装着時に着用者の排血口部及び会陰部に対応する排血口対応部に対して、長手方向中心線の両側にそれぞれ、吸収性物品の略長手方向に沿う部分を有する排血口対応エンボスを形成するとともに、前記排血口対応エンボスより吸収性物品の長手方向後側に離隔して、長手方向中心線の両側にそれぞれ吸収性物品の幅方向外側に曲率中心を有する円弧状の臀部潰れ対応エンボスと、長手方向中心線上の位置から後側に向けて両側に漸次拡大する略逆V字形状部分を有する臀部溝対応エンボスとを形成し、
