ABSTRACT:
A disc cartridge for containing therein an information recording disc, such as a video disc, has a detachable lid which is engaged with an opening of said cartridge. The lid has a pair of engaging means which are integrally formed with the lid body by a synthetic resin. Each of the engaging means comprises a curved lock arm having a projection to be received in a recess made in a cartridge body, and is connected to the end of the lid body at its one end. A plurality of leaf spring elements constitute a zigzag-shaped spring member which is interposed between one end of the lid body and the lock arm. Some of the leaf spring elements have thin and thick portions so that stress applied thereto will be dispersed. In one embodiment, the dimension of the thick portions is selected so that the thick portion abuts against an adjacent leaf spring when the zigzag-shaped spring member is compressed.
