  • Patent number: 5894924
    Abstract: A holder for a compact disc. The holder includes a base approximating the size of a compact disc for nesting a compact disc. A centrally located rosette integrally cast with the base centers the CD. The rosette has engagement arms molded to and extending upwardly from the base for centering the CD, and further extending radially inwardly, creating a circular opening. It also includes a lid pivotally mounted on the base and having a centrally located retaining ring and button fastener for insertion into the circular opening of the rosette as the lid is moved from the open position to the closed position. With the lid in the closed position, the button fastener holds the CD firmly in place and additionally functions as a latch to retain the lid in the closed position.
