Abstract: A burial casket assembly comprises a decorative casket, an insert casket, a base, and a vault cover. The decorative casket receives the insert casket and comprises a decorative container and a decorative cover. The insert casket comprises an insert casket and an insert cover. The decorative casket is supported on the base, and the vault cover is placeable upon the base to encase the decorative casket. The decorative cover is arranged to bear against the insert cover so that when the former is tightened-down, it urges the latter into sealing relationship against the insert container. A hinge arrangement is provided for the decorative casket which enables the cover of the decorative casket to be swung open to either side or completely removed from the decorative container. The floor of the insert container is itself profiled to support the deceased in the traditional posture of repose.
