ABSTRACT:
A plastic case suitable for housing a DVD disk manufactured by assembling a sandwich of heat-sealable members and heat-sealing them together to permanently seal the parts together. The manufacture utilizes vacuum forming of a rigid plastic sheets rather than injection molding to form the critical part of the case that functions to hold the disk on a center hub and that allows release of the disk by pushing down on the center hub. The center hub comprises three projections surrounding and each connected by a valley region to a center button-shaped member. Each projection at its outer edge comprises a detent region projecting above a recessed region beneath which functions to hold the disk in its mounted position above the level of the surrounding sheet surface. The recessed regions terminate below the disk in common, annular surface regions. The circle defined by the outer detent edges is slightly larger than the hole in the disk center such that when a disk is placed on top of the hub, it rests on the beveled edges on top of the hub. Pressing the disk downward causes the circle defined by the outer bevel edges to become slightly smaller than the disk hole which allows the disk to move downward until it rests on the hub. Pressing the hub center causes a one-way toggle action that releases the disk and allows it to be removed from the case.
