ABSTRACT:
A stackable drum as disclosed. At one edge of the top, a water collecting channel is defined having outlet holes communicating with it. The walls of the drum are reinforced. A skirting on the bottom of the drum is received within the lip of the drum beneath. The top, bottom and side walls are adapted to cooperate, when a plurality of such drums are stacked vertically, to pass the weight of an upper drum directly through the rim of the top, through the walls and bottom, and into a third drum stacked below it. A cap seal is applied atop the lid of the drum. It is in the form of a closed pan, with a stopper in it.
