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.

Abstract: A plastic case suitable for housing objects, such as a video cassette, and manufactured by assembling a sandwich of heat-sealable members including a non-heat sealable stiffener member and then moving the assembly to a heat-sealing machine to permanently seal the parts together. To prevent movement of the stiffener member and mis-alignment with the heat-sealable members, one of the heat-sealable members adjacent the stiffener member is provided with a recessed region into which portions of the stiffener member can be pushed and there held in place by an interfering fit until the assembly is permanently sealed together.
