Abstract: A DVD, CD or VCD storage box composed of a body, a cover, a molded hinge mechanism, recesses for opening the box, an annular peak element, an annular rib, a push-down platform, at least one cantilever beam and a surface. The peak element extends upward from the body to support a disc. The push-down platform is surrounded by the peak element. The cantilever beam is also surrounded by the annular peak element. The peak element can also be surrounded by an annular rib. The cantilever beam has a free end with a protrusion formed at the free end to constrain the stored disc. The surface is connected between the push-down platform and the cantilever beam such that the disk is released from the protrusion of the cantilever beam when a load is applied to the push-down platform.
