A burial casket so configured of a non-biodegradable, corrosion-proof material to obtain the required mechanical strength with a minimum of material. The self-sealing gasket made of resilient material helps hold the cover on the casket and compresses at right angles to the direction the cover is put on the casket. An air valve allows the cover to be put on or taken off easily, the casket tested for air tightness, oxygen to be purged from the casket, and an inert gas to be pressurized to slow decomposition of the cadaver in the casket. A relief valve-filter assembly relieves and deodorizes any excessive pressure caused by decompositions gases.

A Casket for a cadaver, said casket having an open position and a closed position, said casket having an interior that is adapted to be hermetically sealed from the exterior of said casket, said casket having parts and components fabricated from a polymer in order to eliminate or minimize the degradation of said casket due to corrosion and/or rotting, said parts and said components being fabricated by various manufacturing methods including but not limited to injection molding, extruding and vacuum forming, said casket having a configuration of a pressure vessel in order to withstand substantially elevated internal and external pressure while maintaining it\s original form and structural integrity, said casket being able to be used for transporting, viewing embalmed, viewing unembalmed, cremating, burying in a vault, burying without a vault and entombing in a mausoleum, cadavers with only minor modifications to said casket, said casket being substantially strong enough structurally to be interred without a burial vault, said casket providing substantial structural strength while maintaining an aesthetically pleasing traditional appearance, said casket comprising; a seamless unitary polymeric container adapted to hold said cadaver, said container having combinations of structural configurations including rounded ends, curved sides, a flange substantially at right angle to the adjacent part of said container around substantially the entire periphery of the opening and a substantially planar bottom reinforced with ribs, to provide stability when said casket is resting on a substantially flat surface, that would allow said casket when assembled to withstand substantial deformation due to internal gas pressure and to withstand substantial deformation due to external pressure of the burial dirt with the additional help of said internal gas pressure thus requiring a minimal amount of said polymer in said container; a seamless unitary polymeric cover adapted to fit on said container to place said casket in said closed position with said cover substantially spanning said container to encompass substantially all of said interior of said casket, said cover having combinations of structural configurations including an elongated dome and a flange at substantially right angles to the adjacent part of said cover around substantially all of the entire periphery of the opening; a gasket that is continuous of a substantially low durometer, resilient polymer that can be bonded to said container around its\entire periphery and having a substantially outwardly and upwardly extended lip that would start to seal said casket as said cover started to be lowered on said container-gasket assembly, said gasket being located between the overlapping parts of said cover and said container so any pressure, internal and external, compresses said gasket, said cover centering itself on said container-gasket assembly, said lip being compressed at a substantially right angle to the direction of said cover as it was being put on said container-gasket assembly and the substantially increased friction between said gasket and said cover would hold said cover on said container-gasket assembly.
