  • Patent number: 5425451
    Abstract: A new and improved compact disc case apparatus includes a lower case assembly and an upper case assembly which are placed in registration with each other to form an enclosure assembly. The enclosure assembly includes a side which contains a slot. A pivot assembly is connected between the lower case assembly and the upper case assembly adjacent to a first lower corner and a first upper corner. A disc retention tray is positioned between the lower case assembly and the upper case assembly. The disc retention tray pivots on the pivot assembly such that the disc retention tray can be selectively moved to an open position or a closed position. In the closed position, the disc retention tray is housed completely in the enclosure assembly. In the open position, the disc retention tray is substantially outside the enclosure assembly such that a disc can be selectively taken off of and placed on the disc retention tray. The disc retention tray includes a handle portion.
