Abstract
An apparatus and method of forming a metallic cup that is subsequently reformed into a container body is provided. More specifically, the present invention relates to an apparatus and methods used to form a metallic cup with a reformed bottom having an inwardly oriented projection. The inwardly oriented projection reduces a height of the metallic cup but utilizes the same amount of metallic stock material as a taller cup with substantially the same diameter that does not have an inward projection. The inwardly oriented projection thus allows the use of a conventional bodymaker and other can manufacturing tools to convert the cup into a container body of a preferred size and shape.
