  • Patent number: 7735642
    Abstract: An ejectable disc case is made up of three pieces—a bottom piece, a top piece, and a movable tray, all of which can formed by injection molding and then assembled together by snap fit. The bottom has a hole through which a disc can be ejected and two bottom grooves engaged by groove mechanisms of the tray. The tray has a disc perimeter support for supporting a perimeter of the disc in the tray in the retracted position, a disc locking mechanism for holding the perimeter of the disc in the tray in the retracted position, a center disc rest connected to the disc perimeter support by a center disc rest slant ramp, and a hook with a hook prong that extends upwardly from the center disc rest. The hook prong moves upwardly through the disc hole and engages the disc center to secure the disc center when the tray moves from the extended position to the retracted position but disengages the disc and moves downwardly through the disc hole when the tray moves from the retracted position to the extended position.

  • Patent number: 5265721
    Abstract: A compact disc container that allows the user to open the container and insert the disc into a compact disc container using only one hand is disclosed. The container includes a tray that holds the compact disc, and slides along two ridges in the container between a retracted position and an extended position. The user controls the sliding of the tray by sliding a knob mounted on the tray and protruding through the cover of the container. When the container is opened along one wall of the container, the tray is slid out of the container to its extended position so as to enable removal of the compact disc.
