Case with members for impeding disc removal

A case for a disc having a central hole, comprising:

• a pair of wings having a hinge joint for allowing said wings to swing between an open and a closed condition, one of said wings being adapted to releasably hold said disc at a predetermined location with clearance at the periphery of said disc to allow loading and unloading of said disc in said open condition without interference, said wings having at least a pair of members, in said closed condition said members transversely extending past said predetermined location in order to interfere with removal of said disc, said pair of members being positioned to avoid overhanging said disc, so that said disk can be loaded squarely and held in said predetermined location without engaging said members, said wings in said closed condition normally meeting along a juncture to provide an encircling enclosure around said members without an opening that would allow removal of said disc, in said closed condition each of said members being disposed from an inwardly facing surface of a supporting one of said wings (a) further than juncture, and (b) to a position releasably engaging an inwardly facing surface of the other wing.
