Abstract
本発明の吸収性物品は、吸収性物品が装着された時に装着者の身体によってかけられる圧縮力に対して耐力を生じさせる強化構造体によって、体液の漏れ防止を改善する。
Description
本明細書において、「生理用ナプキン」とは、女性が外陰部に隣接して装着する物品であって、身体から排泄される様々な滲出物(例えば、血液、経血、及び尿)を吸収及び保持することを意図される物品を指す。しかし、本発明は、衣類の股領域に装着されるパンティライナー、おむつ、及び失禁パッドなど、他の衛生用パッドにも適用できることを理解されたい。
本明細書において、「横方向(transverse)」又は「横に向かった(lateral)」とは、縦方向に対して概ね垂直な、吸収性物品の平面内にある線、軸線、又は方向を指す。本明細書において、「横方向軸線」とは、流体源の区域の中央で縦方向軸線と交差する横方向軸線を指す。
強化構造体70(即ち、強化要素)を形成するチャネル62及び64の総数及び長さは、生理用ナプキン20の設計に応じて変更できる。一実施形態では、生理用ナプキン20は横方向チャネルを2つだけ包含しており、これらは典型的には横方向軸線T上に配置された強化要素を1つだけ形成する(図示せず)。
この方法は、外部からかけられる圧縮に対する試料部材(即ち、吸収性物品)の圧縮弾性率を決定するために使用される好ましい手順について説明する。一般に、この手順には、試料部材のプローブ接触区域において予め定められたプローブによって試料部材が押し下げられた時に発生する力の割合の測定が伴う。測定に際して、圧縮弾性率は、当初の厚さの75%で(即ち、25%のひずみで)試料部材が連続的に押し下げられた時に単位ひずみを引き起こすのに必要とされる圧力kPa(キロパスカル)の割合として測定される。
