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. |
