Abstract:
1. An overpack salvage drum comprising: a drum body for holding a package to be overpacked; a lid adapted to be rotatably threaded onto the drum body to seal the package held in the drum body therein; and a clip adapted to be operatively associated with the lid before the lid is rotatably threaded onto the drum body, wherein the clip is adapted to break in preference to the lid and the drum body when the seal between the lid and the drum body is first compromised; wherein the clip includes a tail portion for contacting camming surfaces of a plurality of projections formed on an outer portion of an intermediate side wall portion of the drum body as the lid is being rotatably threaded onto the drum body, wherein the camming surfaces are adapted to lift the tail portion of the clip over the plurality of projections as the lid is rotatably threaded onto the drum body, and wherein the plurality of projections each further comprises a blocking surface for contacting the tail portion of the clip and thereby inhibiting unthreading of the lid from the drum body.
