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.
Claims16
A container for hazardous materials comprising:
- a can having a closed end and an open end;
- a locking rim located at the open of the cam, the locking rim having a shelf therein of a first inner diameter;
- a lid having an outer surface and an inner surface, the lid having an outer diameter larger than the inner diameter of the shelf wherein when the lid is mounted on the cam the lid is supported on the shelf;
- at least one gasket between the shelf and the inner surface of the lid;
- an array of radially extending locking bolts having inner and outer portions and being slidably mounted on the lid for sliding the outer portions between the locking rim on the housing and the lid;
- a first camming arrangement connected to the inner portions of the locking bolts to project the outer portion of the locking bolts beneath the locking rim when rotated;
- a fulcrum between each sliding bolt and the top surface of the lid;
- a second camming arrangement for engaging the inner portion of the locking bolts to pivot the locking bolts about the fulcrums to move the outer portions into engagement with locking rim and force the lid against the gasket to seal the hazardous materials within the container from the surrounding environment.
