ABSTRACT:
A compact disc tray incorporates a flat planar surface approximating the size of a compact disc for nesting a compact disc. A central rosette molded to the flat planar surface engages the inner center hole of the CD. The rosette has engagement arms molded to and extending upward from the tray for engaging the center hole, and further extending radially inward towards a molded connection with a center button. The molded connection between the center button and inner ends of the engagement arms provides a living hinge and may be accomplished through reduced thickness in the molded material. Pushing of the center button imparts a downward motion on the inner ends of the engagement arms, which thereby angles the upwardly extending portions of the engagement arms away from the engagement with the center hole of the CD. This releases the CD from the rosette.
