Abstract
A composite, drum type container for storing and dispensing corrosive fluids comprises an inner plastic liner of polyethylene and an outer plastic shell. The end walls of the outer shell are substantially dome-shaped to add strength to the container, and the top end wall is further reinforced by an inclined offset wall, ribs, and inwardly protruding portions of the sidewall, to prevent deformation. A separate pressure plate adds to the strength of the dome-shaped bottom end wall. A recess or well in the bottom end wall and pressure plate allows complete removal of the contents of the container.
