Abstract
Abstract A box has a frusto-pyramidal base with a frusto-pyramidal lid hinged thereto. The free edge of the lid has a support tab of a width sufficient to fit within the closed box and rest with its free edge on the bottom of the box thereby to support the lid. A locking tab on the adjacent free edge of the base engages in a slot in the lid between the support tab and the adjacent sidewall of the lid.
