Burial shell and method of making

In a burial shell having a generally flat rectangular, longitudinally-extending horizontal bottom having longitudinal and lateral edges, a pair of opposed side walls and a pair of opposed end walls extending generally vertically upwardly from the longitudinal and lateral edges of the bottom respectively, said walls and said bottom forming an open-top box-like structure adapted to sealingly receive a cover for enclosing said open top and thereby provide a leakproof burial structure, the improvement comprising:

• said shell being produced from thermoplastic material as two substantially symmetrical, longitudinal half-shells, which, when assembled to form the box-like structure, have facing edges joined along a parting line extending generally longitudinally and centrally of the shell, said parting line being generally horizontal along the bottom of the shell and generally vertical along each of said end walls, and,
• means providing a sealed joint along the parting line to form said half-shells into an integral leakproof structure.
