Description
フェイスマスクは、外表面と外表面と反対側に配置された内表面とが付いた本体とフェイスマスクを使用者に取り付けるための固定用部材とを含むように提供される。フェイスマスクはまた、生存できる病原菌の数を減らすのに有効な量の少なくとも1つの殺菌剤を含む。殺菌剤は、フェイスマスクの最外層に配置することができる。殺菌剤は、また、追加層としてフェイスマスクに付加された薄い織物に配置することができるという利点がある。
本発明の実施形態、図で例示された1つ又はより多くの実施例について、詳細な言及が今から行われる。それぞれの実施例は、本発明を説明することによって提供されるが、本発明の限定を意味するものではない。例えば、1つの実施形態の一部として例示され、記述された特徴は、他の実施形態と使用することができ、さらに第三の実施形態をもたらすことができる。本発明はこのような及び他の変形形態及び変更形態を含むということが意図される。
図1は、1つの好適実施形態によるフェイスマスク10の斜視図である。フェイスマスク10は、フェイスマスク10が着用されたときに、使用者14(図2)の顔に面し、かつ接触するのに適するように形成された内表面18を有する本体12を含む。そのマスクは、複数の折り目28を備えてもよく、伸長性部材22もまた備えてよい。伸長性部材22は、本体12の上部縁取り材52が着用者の鼻及び頬上部の輪郭にちょうど合うよう設定できるように提供される。伸長性部材22は、長方形の横断面の金属片から好んで組み立てられるが、成形可能で展性の金属若しくは合金、プラスチック、又はそれらの組み合わせとすることができる。
