A positive interlocking arrangement between two container parts connected pivotably by a joint essentially consists of circular edges in side walls of one part of the container and grooves which are provided in the circular edges and which are engaged by counter-pieces on the other container part which are in the form of sloping surfaces or steps. The container parts can be separated only in the region of a predetermined angle of rotation, in particular in the vicinity of the closed position of the container. Provisions for limiting rotation can advantageously be combined with the interlocking devices. The positive interlocking arrangement can be used for any container which consists of rectangular molded components essentially connected pivotably to one another.

A substantially rectangular storage container for flat articles, in particular magnetic recording media in packages, said container comprising two parts, namely a bottom part consisting of a base wall bordered on two sides by side walls of flexible material and a lid part consisting of a lid wall at least partly bordered at the sides by side walls, and a hinge device between the bottom part and the lid part to permit pivotal movement therebetween about a stationary axis, wherein each of the side walls of one of the container parts, on the side thereof facing the respective side wall of the other container part, has a first interlocking part, including a first part-circular edge portion extending concentrically about said axis and undercut in a direction radially outwardly from said axis to form a first part-circular groove whereas each of the side walls of the other container part, on the side thereof facing the respective side wall of the first-mentioned container part, has a second interlocking part which is substantially complementary to the first interlocking part and includes a second part-circular edge portion designed to mate with said first groove, and undercut in a direction radially inwardly from said axis to form a second part-circular groove designed to mate with said first edge portion, said interlocking parts being dimensioned so as to effectively engage each other over only a predetermined extent of said pivotal movement, whereby lateral spreading apart of said side walls of the bottom part, in a direction substantially parallel to the pivotal axis of said parts, to an extent permitting mutual axial disengagement of said parts is prevented only over said predetermined extent.
