Abstract
The invention includes a novel profile for a container bottom and method of manufacturing the improved bottom. The improvement involves the creation of an additional angled portion in the inner leg area of a container bottom during the formation of the bottom profile during the bodymaking step. Known container bottom profiles have a single portion in the inner leg area after the bodymaking process. The inventive profile includes the following discrete portions starting at the nose of the container bottom and working inwards towards the central axis: a nose, a substantially linear lower leg portion projecting upwards from the nose, a separate angled portion between the lower leg portion and the dome inclined generally at an angle more towards the longitudinal central axis of the container than the angle of the lower leg portion, and a dome.
