Abstract
A nestable drum is provided with a tubular shell having a lower section and a top section of increased diameter joined by an integral step located approximately at the shell middle. The larger diameter top section is adapted to conveniently receive the reduced bottom section to facilitate nesting when drums are stacked one upon the other. The step is formed with a series of spaced reinforcing gussets which are adapted to rest on the top end of a lower drum in the stack. The top of the shell is necked-in and possesses a diameter less than that of the top section and is curled outwardly to provide a bead which receives a cover locked in place by a split clamping ring. One form of cover is provided with an indentation which is adapted to receive the bottom closure of a stacked drum to lock it in place and thereby prevent any relative sliding.
