ABSTRACT:
The invention includes a novel profile for a container bottom. The bottom structure includes a domed central panel attached at its outside edge to a downwardly projecting substantially cylindrical inner leg portion. The inner leg portion is attached to a generally semi-circular nose portion. The outside of the nose portion is attached to an upwardly and outwardly inclined outer leg portion. The outer leg portion is attached to an outwardly inclined peripheral portion. The peripheral portion is attached to the lower end of the generally cylindrical sidewall portion. The improvement primarily involves the larger stand diameter, and altered dome circle radius and dome depth, which produces a container bottom profile yielding more consistent results in drop tests to determine resistance to bulging and reversals (single can and consumer package flat and angled drop tests) than prior art can bottoms.
