Abstract: There is a gap between the respective inner regions of the end face of the cylindrical side wall and the abutting portion of the top plate, which are situated inside the seal member. Even though the top plate is bent inward by atmospheric pressure when the container is decompressed to a predetermined degree of vacuum, therefore, the abutting portion thereof cannot come into contact with the inner edge of the end face of the cylindrical side wall. Thus, if decompression and exposure to atmospheric pressure are repeated to bend the cylindrical side wall repeatedly, there is no possibility of the inner edge portion of the end face of the cylindrical side wall being separated or rubbed off to produce dust. Moreover, the cylindrical side wall and top plate are joined together in the region outside the seal member. If dust is produced by the contact between the cylindrical side wall and top plate at their junctions outside the seal member, therefore, it is prevented from entering the container by the seal member.

Abstract: A modular knock-down packing container system, generally of wood, includes interchangeable wall panels with corresponding channel guides for guaranteeing the structurally reinforcement and sealing of the interchangeable walls. The panels are held in place by a combination of the position of the panels within corresponding channel guides and of the use of central sphere rod connectors, which connectors may be rapidly and easily loosened for dismantling of the packaging system, so that the panels can be re-used in other configurations. A systematic plurality of wall panels is provided with incremental dimensioned variations, so that the size of the containers can be varied while preserving the ability to create large hollow interiors uninterrupted by perpendicular floor members. Expansion of the size of the containers is also accomplished without limiting interior container storage space by axial connection of the stacking of the panels end over end.
