Abstract

A method and apparatus for reforming the bottom of a container (20) and a container made by that method is disclosed. The container for which this method and apparatus are suitable has an outer annular wall (26); a convex U-shaped portion (28); a preformed bottom wall (30), including a center domed portion (32); and an annular wall (34) joining the domed portion and the convex U-shaped portion. The method comprises supporting the bottom peripheral profile portion and bringing a reforming means (36) into engagement with the annular wall. The reforming means is brought to bear against the annular wall to rework the annular wall. The reforming means can also reform the outer annular wall.
