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.

A box blank foldable to form a box having a bottom and four sidewalls, said blank comprising: a nominally planar bottom member having four edges in rectangular array, said bottom member having a top surface; four nominally planar sidewall members, each said sidewall member having an edge, each sidewall member being adjacent to a respective one of said edges of the bottom member, the pairs of sidewall member edges and bottom member edges being adjacent to each other, the members of said pairs being laterally spaced apart from one another along a respective fold axis; a strap hinge respective to each said pair of edges joining the said members together, said hinges being flexible, whereby to permit rotation of said members relative to one another around said fold axis; and a stabilizer member comprising a tooth adjacent to one of said edges of each one of said pairs of edges and a recess adjacent to the other one of said edges of each of one of said pairs of edges, each of said sidewall members having either a said tooth or a said recess and each edge of said bottom member having a complementary said recess or said tooth, said tooth and said recess each having a restraint face which, when engaged by the other restrains the bottom member and respective sidewall member from lateral translational separation normal to said fold axis along the plane of one of said member, said tooth and recess being so disposed and arranged as to be interengaged with one another when the blank is folded with the plane of the sidewall member substantially normal to the plane of the bottom member.
