The parts of the casket are longitudinally, slidably interconnected together such that each successive part of the casket interfits and interlocks with the others. Thus the bottom, sides, ends, and top interfit in a fashion that the assembly of the top locks the bottom, sides, and ends and prevents movement of the bottom, sides, and ends in any direction to form a rigid, unitary, complete casket obviating the necessity of any further fastening elements of any kind. In the preferred embodiment, no hardware of any kind is required in the assembly of the casket. Therefore, the casket according to the teachings of the present invention meets certain religious requirements and allows a dignified burial while avoiding excessive costs.
