  • Patent number: 5788068
    Abstract: An apparatus for holding a compact disk has a base portion and resilient inwardly extending radial arms, cantilevered from the base portion; the inner ends of the arms form a button-like member receivable in the central hole of the disk so that pressure applied to any one or more of the inner ends of the arms flexes each of the arms toward the base portion to move the inner ends of the arms toward each other sufficiently to release the button-like member from the disk. Lips on the button-like member retain the disk by engaging on the outer surface of the disk. Resilient ejection means may be provided to urge the compact disk out of engagement with the button-like member, and disk support means may be on the base portion to support the disk at positions away from the central hole of the disk. The apparatus may be formed as a one-piece plastics molding as a tray for insertion in a box or as part of a wall of a video style library box.
