Abstract

Abstract A mask to protect physicians, dentists and technicians from spatter from patients afflicted with various diseases (including A.I.D.S.) is assembled from two parts, which may be shipped and stored flat. The visor is formed of a flat piece of sheet rubber formed with transverse slits so that the visor may be attached to ordinary eyeglasses. The shape of the visor provides a curved, forward extending bill. Slits are formed near the outer edge of the visor. A transparent shield has dovetail projections on its upper edge which snap through the slits. Other cooperating fastening means may be used to assemble the visor and shield and also to hold the visor on eyeglasses. The shield is supported by the visor and hangs down to about the chin, protecting the eyes, nose and mouth.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 199 words
A face mask comprising an integral visor, said visor being formed of an initially flat resilient, flexible sheet of rubber-like material bent to assume a visor shape when said visor is attached to the eyeglasses of a user, means for attaching said visor to eyeglasses worn by the user, said visor being formed with an inner edge shaped to fit against the forehead of the user and a curved outer edge, said visor being substantially horizontal when in position of use, said visor being formed with a plurality of spaced slits through said visor spaced along said outer edge, and a removable shield formed of a sheet of flexible plastic transparent over at least a substantial portion of its area, said shield having an upper edge formed with projections, said shield and said projections being formed together as a one piece structure, said projections dimensioned to be resiliently forced through said slits and preventing unintentional detachment of said shield from said visor, so that said shield is supported by said visor extending substantially vertically, said shield being shaped and dimensioned to extend down and around the face of the user to protect the eyes, nose and mouth from contamination.
