  • Patent number: 6464073
    Abstract: A compact disc holder includes a base portion, a rigid column extending laterally upward from the inner surface of the base portion to an inner end, and at least one resilient arm extending laterally upward from the inner surface of the base portion to a upper end disposed within a laterally extending bore of the column. The upper end portion of the arm forms an actuator member having an upper surface which is positioned below the inner end of the column. Longitudinally extending first and second disc-retaining lips on the column and arm, respectively, are inserted through the central opening of a compact disc to engage and retain the compact disc. The compact disk is released by inserting an object into the bore of the column to engage and apply pressure to the upper surface of the actuator member, depressing the resilient arm toward the inner surface of the base portion and pivoting the second disc-retaining lip away from the compact disc.
