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. The bottom side wall through which the disc is ejected has one or more downwardly sloping ramps to actuate disengagement of the disc from the hook prong as the tray moves from the retracted position to the extended position. The tray can have multiple tray holes within the disc perimeter support to decrease the amount of material required for construction of the tray.
