Design of Rigid Package Container with Telescopic Mechanism Used in Ultra High Pressure Food Processing

A novel structure of rigid package container (RPC) used in ultra high pressure food processing was presented, due to single and flexible food package occupying large volume and less repeat usage. This new container was designed in details, such as mechanical analysis on sealing process of o-rings and structural optimization on its key components of RPC. Experiments on the sealing properties had proved that this structure was reasonable and reliable in sealing, easy to assembly and disassembly, compact structure and light weight. Thus, the RPC could be applicable in many ultra high pressure vessels in food industry.
