ABSTRACT:
The invention refers to plastic drums designed such that the bottom of the drum will interlock with the lid of another drum. This feature enables the drums to be placed in stacks that are stable, so they can be safely handled during shipping, storing, or handling operations. The drums are also designed so they can be stored in a nesting column, when empty, without the drums becoming wedged together in the column.
