Abstract: A storage container for hexahedron objects, such as mini-disk cartridges and promotional material. The container comprises two primary components, a base tray and a cover, where the base tray is constructed such that it may house two hexahedron objects. The base tray, which has two parallel side walls, is formed with a ledge extending inwardly from each of the side walls such that one object may be stored on top of the ledges and another object may be secured below the ledges. The cover is constructed with support extensions for supporting the cover and securing the object resting on the ledge when the container is in the closed position.

Abstract: A method is disclosed for testing the integrity of a container of the type which includes a thin walled cup and a flexible lid sealed to the rim of the cup. In accordance with the method a force is applied to an elongated portion of the lid which circumscribes an area which is coaxial with the center of the cup. Since the cup is sealed this application of force causes the circumscribed area to bow outwardly from the cup. The displacement of the bowed portion is then compared to the previously measured displacement for containers known to be of acceptable quality. An apparatus for performing the test has an upper test assembly with a rim which is adapted to be urged against the elongated portion of the lid. A displacement sensor is mounted within the upper test assembly.
