Abstract

A tray for holding a compact disc wherein the tray comprises a plate having a central region, an annular array of fingers in the central region for receiving the opening of the compact disc and an impact resistance shield within and below the annular array of fingers for receiving impact forces directed toward the fingers and for distributing the forces to the plate so as to protect the fingers from breakage upon impact. The impact resistance shield comprises a central body portion or core and a plurality of radially outwardly extending arms or tentacles located between adjacent fingers and extending into the plate. During impact the central body portion or core radiates the energy of impact directly outwardly and acts as a buffer for the fingers. The central core has a concave outwardly directed face positioned below the tips of the fingers which allows room for the fingers moving downwardly without hinderance for easy removal of the compact disc. The central core of the shield means can be located above the surface of the plate to allow room for the central region of another tray to fit in and to facilitate stacking of a number of trays.
