Abstract
Discs are held locked in a tray by flex arms with disc-retaining extensions overlying inner peripheral areas adjacent the central opening of the uppermost disc. A push button is held within a disc-centering boss. Lock tab detents extending from the push button hold the push button above an inner edge of an annular shelf on the centering boss. The push button is connected to the flex arms with goose neck connectors. Pressing inward on the flex arms tends to move the goose necks to draw the push button downward. In the locked, tamper-evident position, the lock tabs prevent the push button from moving downward, and thus hold the disc-retaining extensions over inner surface areas of the disc.
