Abstract
A bellows-type shock absorbing container includes a lower main base member, and an upper closure, which may be mounted to the main base member by engaging threads, or by using a hinge and latch closure. The base member is provided with an inwardly directed rib or shoulder having an upper surface upon which the mounting flange of a waste pump or other delicate equipment to be transported, is mounted. The top closure is provided with a downwardly directed cylindrical extension, which bears on the upper surface of the flange of the equipment to be transported to hold it firmly in place. Both the top cover member and the base include reentrant bellows-type structures which provide resiliency and resistance to shock. In addition, the molded top and bottom, after they are threaded together, completely seal the unit to enclose all possible fluids or odors from the equipment being transported. The container is preferably made of molded plastic having some inherent flexibility, to provide the resilience needed in the shock absorbing bellows arrangements.
