ABSTRACT:
A box folded from a box blank. The box blank has a nominally planar bottom member and four nominally planar sidewall members. The sidewall members are disposed in a cruciform array. Each of said members has an edge. Respective edges of the bottom member and sidewall members are adjacent to each other in pairs, and are laterally spaced apart from one another along a respective fold axis. A strap hinge is respective to each pair of edges, joining the members together whereby to permit rotation of the members relative to one another along the fold axis. A tooth is formed on one of the members and a recess is formed in the other of the members, the tooth and recess each having a restraint face which when engaged by the other restrains the member from lateral translational separation normal to the fold axis along the plane of one of the members. The box blank is preferably made of molded plastic and can be formed in a single piece.
