Embossed gasket

Claim 1

An embossed gasket for providing a seal between a pair of confronting surfaces, at least one of which defines an opening, the gasket adapted to be compressed between said pair of confronting surfaces including a body comprising a metallic sheet and having a pair of spaced apart major surfaces defining at least one aperture therethrough adapted to surround said opening, the body having only one elongated embossment surrounding at least a portion of said aperture and spaced away from said aperture for effecting sealing at the zone of the embossment, said embossment comprising a projection extending outwardly from one major surface and a corresponding indentation extending inwardly from the other major surface, and a resilient elastomeric sealant material screen printed and disposed in and partially filling the indentation whereby when the embossment is compressed between the two confronting surfaces, said elastomeric material provides support for said embossment to prevent the embossment from flattening out, thereby to concentrate the sealing effect of the embossment in the zone of the embossment when said gasket is compressed between said pair of surfaces, whereby leakage between said confronting surfaces is prevented and the sealing effect of the gasket is enhanced.
