ABSTRACT:
A gasket for a casket is an endless integral rubber element that extends around the perimeter of the casket and seals the lid to the shell. The gasket has a wide base and at its outer edge an upwardly-projecting ridge which is approximately triangular in cross section. The outer surface of the ridge is concave to promote the flexing of the ridge outwardly when the lid is closed upon the shell. The tip of the ridge and the underside of the gasket have continuous ribs that form the seals to the lid and shell, respectively.
