Abstract
An overpack salvage drum including a drum body and a lid. A bottom wall and side wall of the drum body cooperate to define an interior of the drum body. The lid is configured to close an open top of the drum body. The lid includes at least two independent lid threads to engage with corresponding independent drum threads provided on the drum body. The lid includes a plurality of alternating castellations having a flat inner facing side and castellations having an arcuate inner facing side, which can be interdigitated with castellations on another lid when two lids are stacked together, or can be used to lock with a drum body to rotationally secure a drum body relative to the lid when in a stacked arrangement. The lids include lugs and recesses, or rings that allow for secure stacking of the lids.
