  • Patent number: 5660274
    Abstract: An improved tray (10) for compact discs (12) is provided herein. The tray (10) comprises a body member (16), a plurality of spaced-apart retainer tabs (20) and a plurality of stops (22). Each retainer tab (20) has a proximal end (72) attached to the body member (16), a distal end (74) extending away from the body member (16) which is capable of deflection between a relaxed position (76) and a deflected position (78) and a disc contact surface (80) for holding the disc (12) to the body member (16) by engagement with the disc (12) at the disc aperture (14) in the disc (12). The plurality of stops (22) prevent the retainer tabs (20) from overdeflecting during installation of the compact disc (12) onto the tray (10). Thus, the tray (10) can be made of clear, hard scratch-resistant plastic.
