发明名称 Cushioned overpack for containing hazardous substances
摘要 Cushioned overpacks are employed for containing, transporting, and storing discarded electrical transformers contaminated by toxic materials such as polychlorinated biphenyls (PCB's). Other articles may be similarly contained, transported, and stored using such cushioned overpacks. The discarded transformers are then consigned to such overpacks together with one or more cushions. The cushions serve to prevent puncturing of the overpack by the transformers during transport and storage. Preferred cushions have a foam composition and are inserted into the overpack by means of a pour-in-place process. Preferred overpacks include an inner surface which is roughened so as to adhere to the inserted cushion. After the insertion of the transformer and cushion is complete the assembly is hermetically sealed by a spin welded closure onto the receptacle. Uncushioned overpacks are fabricated at or near the process site by rotational molding. As such, they may also be employed for securing medical waste for subsequent incineration and for stabilization of contaminated soil.
