Abstract

A light-weight, disposable face shield assembly for the protection of the eyes and face of a wearer from accidental exposure to infectious, hazardous or undesirable substances. The shield assembly includes an elongated, semi-flexible head support strip divided into four foldable segments and a rectangular, semi-flexible, transparent protective face panel affixed at its upper edge portion to an intermediate face panel support segment of the head support strip. The intermediate face panel support segment is bounded on one side by a forehead support segment of shorter length than the face panel support segment and on the other side by first and second head support segments. Proximate the free end of the forehead support segment there is an assembly slot and at the fold line junction between the face panel support segment and the first head support segment there is a mating assembly slot whereby upon the interlocking of such slots the longer intermediate panel support segment is caused to bow outwardly in arcuate spaced orientation with respect to the forehead support segment. The free end portion of the second head support segment includes a series of equally spaced head strip sizing slots and at the fold line junction between the forehead support segment and the face panel support segment there is a mating assembly slot whereby upon the interlocking of a selected head strip sizing slot with the assembly slot of such fold line junction there is formed by the forehead support segment and the first and second head support segments an arcuate strip for surrounding the head of a wearer and for supporting the shield assembly on the wearer's head.
