Description
以下に詳述された用語は、定義された意味を有することになる。
「備える(又は備えている)」は、特許専門用語において標準であるその定義を意味し、「含む」、「有する」、又は「含有する」とほぼ同義である制約のない用語である。「備える」、「含む」、「有する」及び「含有する」、並びにこれらの変形は、一般的に使用される制約のない用語であるが、本発明は、「本質的に〜から成る」等のより狭義の用語を使用して適切に記載することもでき、これは、本発明の呼吸マスクがその意図される機能を果たす際の性能に対して、悪影響を及ぼす物体又は要素のみを除外するという点で、制約のない用語に準ずる用語である。
「フィルタ」又は「フィルタ層」は、空気透過性材料の1つ以上の層であって、その層を通過する空気流から汚染物質(粒子等)を除去することを主な目的とするように適合されている層を意味する。
「呼吸マスク」は、人により着用されて、呼吸するのに清浄な空気を着用者に提供する空気濾過装置を意味し、
「剛性」は、単なる人の指からの圧力に応答して、実質的にかつ容易にたやすく変形しないことを意味する。
「支持構造」は、通常の取り扱い下でその所望の形状を維持し、またその支持構造により支持される濾過構造の意図される形状を維持することを助けるに十分な、構造的一体性を有するように構成された構造体を意味する。
呼吸マスク支持構造のサンプルを、標準的な射出成型プロセスを用いて作製した。図1〜図3に示した支持構造の形状に一致する単一キャビティの雄型及び雌型の金型を、工作機械メーカーにて製造した。弛緩した状態で、又は支持構造が金型上に尚存在する間、支持構造は、頂部から底部まで約115mm、側部から側部まで約120mmと測定された。測定は、呼吸マスクが応力を受けない状態にある間、それぞれ、周縁部の最高地点と最低地点との間、及び側部周辺部材の外側端部の間の直線に沿って行った。支持構造を構成する部材の目標とされた厚さは、2.5ミリメートルであった。横方向に延びる部材に台形の断面を付与して、支持構造がより容易に金型から除去されるようにした。横方向に延びる部材の断面積は、約2〜5mm2の範囲であった。フランジ及びバックルは、本願と同日出願の、可撓性ストラップ取り付け部材を有するバックル、及びそのようなバックルを使用した呼吸マスク(Buckle Having A Flexural Strap Attachment Member And Respirator Using Such Buckle)と題された米国特許出願第60/994,644号(代理人整理番号63577US002)における形状及び構成を有する。ポリプロピレン/熱可塑性エラストマー混合物を、白色顔料と共に押出成形機内に供給した。トータル(Total)製のプロピレン5724を58重量%、クラレ(Kuraray)製のSepton(商標)2063を40重量%、及びTiO2顔料を2重量%で使用した。
呼吸マスク濾過構造を、50グラム/平方メートル(gsm)の一つの白色不織布繊維性スパンボンド材料の外側層と、同一の幅を有する22gsmの一つの白色不織布繊維性スパンボンド材料の内側層との間に積層した、254mm幅の不織布繊維性エレクトロレットフィルタ材料の2つの層から形成した。不織布繊維性スパンボンド材料の両方の層は、ポリプロピレンで形成した。エレクトロレットフィルタ材料は、3M 8511 N95呼吸マスクに使用されている標準的なフィルタ材料であった。積層されたウェブブランクを長さ254mmの部分に切って四角形を形成した後、カップ形態に形成し、これを支持構造と合わせた。
顔面シール:標準的な3M 4000シリーズ呼吸マスク顔面シール。
鼻クリップ:標準的な3M 8210 Plus N95呼吸マスクの鼻クリップ。
ヘッドバンド:標準的な3M 8210 Plus N95呼吸マスクのヘッドバンド材料であるが、色は白色である。3M 8210 Plus呼吸マスクのヘッドバンド用の黄色顔料を除去した。
