Description
本明細書で使用するとき、次の用語は、次の意味を有する。
図1は、本発明による吸収性物品の好ましい実施形態としてのおむつ20の平面図である。おむつは、収縮させずに広げた状態(即ち、弾性によって収縮させていない状態)で示してある。構造の一部を切り取って、おむつ20の下層構造をより明瞭に示している。着用者に接触するおむつ20の部分が、観察者に向いている。図1のおむつ20のシャーシ22は、おむつ20の本体を構成する。シャーシ22は、液体透過性トップシート24及び/又は液体不透過性バックシート26を包含する外側カバーを備える。また、シャーシには、トップシート24とバックシート26の間に挿入させた吸収性コア28の大部分又は全部が包含されていてもよい。シャーシは、好ましくは、サイドパネル30、レッグカフ32、及び腰部機構34を更に包含する。レッグカフ及び腰部機構は、典型的には弾性部材33を備える。おむつ20の1つの末端部は、おむつ20の前腰部領域36として構成される。反対側の末端部は、おむつ20の後腰部領域38として構成されている。おむつ20の中間部は、前腰部領域36と後腰部領域38との間を長手方向に延びる股部領域37として構成される。股部37はおむつ20の一部分であり、おむつ20を着用した時に着用者の脚の間に来る部分である。腰部領域36及び38は、好ましくは後腰部領域38に取り付けられた締着部材40と、前腰部領域36に取り付けられたランディング領域42とから構成される締着装置を包含してもよい。おむつ20は、長手方向軸及び中心線100並びに横断方向軸及び中心線110を有する。おむつ20の周囲は、おむつ20の外側縁部によって画定され、長手方向縁部44はおむつ20の長手方向軸100にほぼ平行をなし、終縁部46は、おむつ20の横断方向軸110とほぼ平行をなす。
「不織布布地」とは、摩擦及び/又は粘着及び/又は接着により結合された、指向性繊維又はランダムに配向された繊維で製造されたシート、ウェブ、又は詰め物(batt)であり、紙と、更なるニードル加工の有無を問わず、結合糸若しくは長繊維を組み込んだ織り製品、編み製品、タフテッド製品、ステッチで結合した製品、又は湿式粉砕によるフェルト製品とを除く。
本発明に関して用いるのに好ましいトップシートは、柔軟で、ソフトな感触で、及び着用者の皮膚に刺激がないものである。更に、トップシート24は、液体(例えば、尿)がその厚さを容易に貫通できる、液体透過性であるべきである。好適なトップシート24は、例えば、多孔質発泡体;網状発泡体;孔あきプラスチックフィルム;あるいは天然繊維(例えば木材繊維若しくは木綿繊維)、合成繊維(例えばポリエステル繊維若しくはポリプロピレン繊維)、又は天然繊維と合成繊維との組み合わせによる織布ウェブ若しくは不織布ウェブなどの、広範囲の材料から製造されてもよい。好ましくは、トップシート24は、着用者の皮膚を、吸収性コア28内に収容された液体から離しておくために、疎水性材料から製造される。あるいは、トップシート24は、それを親水性にするために界面活性剤処理されてもよい。
上記の繊維及び製造技術のすべては、本発明によるコアラップシートを提供するために有用であり得る。
