  • Patent number: 7413076
    Abstract: A storage case for a generally planar item such as a compact disc. The case (10) has a pair of faces (12) adapted to distort when a compressive force is applied parallel to the plane of the disc (34). The case (10) also includes a retaining mechanism (14, 30) between the faces (12) that is adapted to hold the disc (34) in the case (10) when relaxed and adapted to urge the disc (34) out of the case (10) when the faces (12) are distorted by a force applied thereacross. Thus, the case (10) is easy to open and close and in the closed position protects the disc (34) from shock. Furthermore, a single action both opens the case (10) and offers the disc (34) out of the case for easy retrieval. The case (10) can also be adapted to clean the disc (34) as it is inserted into or withdrawn from the case.
