  • Storage container
    Patent number: 7726507
    Abstract: A container for hazardous wastes, such as, plutonium wastes, includes a can and a lid wherein the lid is locked to and sealed with respect to the can by radially projected locking bolts. In order to lock the lid to the can the bolts are cammed radially by rotating a U-shaped handle to place the locking bolts behind a locking rim at the mouth of the can. The bolts are then pivoted to apply an axial force to the locking rim to urge the lid against a gasket to seal the lid by turning a threaded axial force element to pivot the locking bolts on the fulcrums.
