Abstract
Description
本明細書で使用するとき、以下の用語は、以下に記載のように定義される。
マスク本体は、所望により、1つ以上のマスクパネルに剛性化層を含んでもよい。剛性化層の目的は、その名称が暗示するように、他のパネル又はマスク本体の部品に対するパネルの剛性を向上させることである。剛性化パネルは、ユーザの顔面からマスク本体を支持しやすくする。剛性化層は、パネルの任意の組み合わせに位置してもよいが、好ましくは、マスク本体の中心パネルに位置する。マスクの中心に支持体を与えることは、マスク本体が、使用中ユーザの鼻及び口上で崩壊するのを防ぎやすくし、一方、最上パネル及び底パネルを、着用者の顔面の密封に役立つのに比較的適合した状態に保つ。剛性化層は、パネルの層状構造内の任意の点に位置してよく、典型的には外側カバーウェブ上又はその付近に位置する。
本発明のマスク本体で用いられるフィルタ層は、粒子捕捉又は気体及び蒸気型であってもよい。フィルタ層はまた、例えば液体エアゾール又は液体のしぶきがフィルタ層に浸透することを防ぐために、液体がフィルタ層の片側から別の側へ移動するのを防ぐバリア層であってもよい。類似した又は異なるフィルタ型の複数の層を用いて、その用途で必要とされるような、本発明の濾過層を構築してもよい。本発明の層状マスク本体で有益に使用されるフィルタは、マスク着用者の呼吸労力を最低限に抑えるために、一般に圧力低下が少ない(例えば、13.8パーセント/秒の面速度で、約196〜294Pa(20〜30mm H2O)未満)。濾過層は、更に、可撓性であり、一般に予期される使用条件下でその構造を維持するように、十分な剪断強度を有する。粒子捕捉フィルタの例としては、微細無機繊維(ガラス繊維のような)又はポリマー合成繊維の1つ又はそれ以上のウェブが挙げられる。合成繊維ウェブは、メルトブローンのようなプロセスから製造される、エレクトレット帯電ポリマー超極細繊維を含んでもよい。表面がフッ素化され、エレクトレット帯電しているポリプロピレンから形成されたポリオレフィン超極細繊維は、粒子捕捉用途で特に有用である。フィルタ層はまた、呼気から有害な気体又は悪臭のする気体を除去するための吸着成分を含んでもよい。吸着剤は、接着剤、結合剤又は繊維質構造によりフィルタ層に結合された粉末又は顆粒を挙げることができる。米国特許第3,971,373号(ブラウン(Braun))を参照のこと。吸着層は、繊維質又は網状発泡体のような基材をコーティングし、薄い凝集性層を形成することにより、形成できる。活性化炭素のような、化学的に処理された又はされていない吸着材料、多孔質アルミナ−シリカ触媒基質、及びアルミナ粒子は、有用でありうる吸着剤の例である。
着用者の顔面に接触する平滑面を提供するために、内側カバーウェブを用いてもよく、濾過層及び剛性化層から緩んだ繊維を捕捉するために、又は審美的理由から外側カバーウェブを用いてもよい。カバーウェブは、典型的には、マスク本体に著しい保形性を提供する訳ではない。好適な程度の快適性を得るために、内側カバーウェブは好ましくは比較的低い基本重量を有し、比較的細い繊維から形成される。より具体的には、カバーウェブは約5〜50g/m2(典型的には10〜30g/m2)の基本重量を有し、繊維は3.5デニール未満(典型的には2デニール未満、より典型的には1デニール未満)である。カバーウェブで用いられる繊維は、約5〜24マイクロメートル(μm)、典型的には約7〜18μm、より典型的には約8〜12μmの平均繊維直径を有することが多い。
