| Abstract: |
This invention relates to a protective mask, and more particularly to a protective mask usable during the act of oral sex or during the performance of mouth-to-mouth resuscitation to protect a wearer against infection with communicable diseases including viral diseases such as the human immune virus which leads to the development of acquired immune deficiency syndrome (AIDS). The mask is formed by an elongate, generally planar membrane of a tough film material having, when lying flat, a longitudinal axis and an outline configuration which is asymmetrical about that axis, the outline configuration having a lateral extension portion for extending downwardly and rearwardly over the chin of a wearer. The mask is securely wrapped in place over the lower face of a wearer while permitting free movement of the jaw, lips and tongue of the wearer and includes a flaccid pouch-like central portion.
