Tape cassette container

Claim 1

A protective container for a tape cassette comprising a bottom part having spaced apart axially aligned hinge pins, a lid part having a pouch, the walls of the pouch, which have outside portions, having groove-shaped recesses formed therein in which said hinge pins are received to form two pivot joints for enabling the lid part to be pivoted relative to the bottom part from a closed position in which said parts have substantially the shape of a flat, rectangular parallelepiped, and a pair of studs in the vicinity of the pivot joints, said groove-shaped recesses extending substantially vertically, and said studs being located substantially vertically above or below the hinge pins, when the lid part is in the closed position and the container is lying flat and horizontally, so that the engagement of said studs by the walls of said recesses tends to hold the lid part in said closed position, and, after said lid part has been manually moved out of said closed position, engagement of said studs by said outside portions of the walls of said pouch limits the angle to which the lid part can be opened to an angle of substantially less than 180° from the closed position.
