Patent number: 6837089Abstract: A reforming assembly for simultaneously reforming and reprofiling a bottom portion of a metallic container is provided. The reforming assembly generally includes a roller block having a pair of reform rollers and two pairs of outside reprofile rollers. A biasing means is operably interconnected to the reform rollers, such that the reform rollers extend to contact the inner surface of the bottom portion of the container when contacted by the bottom portion of the container. The outside reprofile rollers engage with an outer surface of the bottom portion of the container. The container reforming assembly is rotated, while maintaining the container body in a static non-rotating position, to create an internal can profile on the inner surface by the pair of reform rollers, and an external can profile on the outer surface by the outside reprofile rollers.Type: GrantFiled: April 3, 2003Date of Patent: January 4, 2005Assignee: Ball CorporationInventor: K.

Patent number: 6616393Abstract: Movement of rollers used for reforming an inner wall of a metal container bottom such as an aluminum beverage container is controlled at least partially using a rigid link coupled to other components of a reformer apparatus by a pin having a stepped profile. The stepped-profile pin preferably defines first and second shoulder regions. Undesired spaces or gaps in the pin-axial or thrust direction are reduced or eliminated by closely-positioning bushing flanges or thrust washers adjacent the shoulders.Type: GrantFiled: February 7, 2000Date of Patent: September 9, 2003Assignee: Ball CorporationInventor: K.

Patent number: 6293421Abstract: A beverage container with increased strength includes a generally cylindrical sidewall that is disposed around a vertical axis, and a bottom. The bottom provides a supporting surface and includes a bottom recess portion that is disposed radially inwardly of the supporting surface. The bottom recess portion includes a concave domed panel that is disposed a positional distance above the supporting surface by a dome positioning portion of this bottom recess portion. The domed panel includes a portion thereof with a curvature in the range wherein increases in the curvature decrease the static dome reversal pressure; and the dome positioning portion includes first and second parts thereof that are disposed at different radial distances from the vertical axis and that provide increases in both roll-out resistance and static dome reversal pressure.Type: GrantFiled: June 9, 2000Date of Patent: September 25, 2001Assignee: Ball CorporationInventors: K. Reed Jentzsch, Otis H. Willoughby, Gary A. Baldwin

Patent number: 6293422Abstract: An aluminum one-piece container body, defining a sidewall and bottom, has a substantially hemispherical or otherwise convex, preferably curvilinear, surface surrounding a central concave panel. A plurality of feet extend downwardly from the convex region. The convex region provides strength advantages associated with containing pressurized material. A concave panel accommodates changes in differential pressures such as arising from pasteurization or other heating. The feet are preferably configured to provide substantial stackability and conveyability as well as support stability for the container.Type: GrantFiled: March 8, 2000Date of Patent: September 25, 2001Assignee: Ball CorporationInventors: K.
