Disposable full-face surgical mask

Claim 1

A comfortable, lightweight, disposable face mask for substantially, fully or completely covering the face and the front of the head of the wearer and having means for securing said face mask on the head of the wearer, said face mask comprising: a unitary shell formed of a single piece of thin, transparent plastic material, said shell having an upper portion and a lower portion and having a generally oval periphery, said upper portion having a generally bulbous configuration and being large enough to accommodate the eyeglasses, if any, of the wearer, and being shaped so as to substantially prevent parallax and distortion of the vision, when the mask is worn, said lower portion, for covering the mouth and nose of the wearer, having a region thereof comprised of an air filtration medium; said upper portion and said lower portion being joined along a shaped ridge which, when the mask is worn, projects toward the face of the wearer, said ridge having attached thereto a band which, when the mask is worn, contacts the nose and face of the wearer, thus substantially preventing breath exhaled by the wearer from reaching said upper portion of the mask; said face mask having a strip of soft, flexible material attached to the entire periphery of the mask and extending inwardly of the periphery of the mask, said flexible strip and said band being the only portions of the mask which contact the face of the wearer when the mask is worn.
