Abstract: A method and apparatus for providing a contoured design confirguration in the wall of an open ended container workpiece employs plural molds on a rotating turret an which a plurality of molds are provided with each mold having an inwardly facing wall having the desired configuration. The workpiece is delivered from a pneumatic conveyor and vacuum star wheel into an open mold which then closes and the interior of the workpiece is pressurized with air. A rotary wand moves into the workpiece and discharges high velocity rotating liquid jets against the inner wall surface of the workpiece to forcefully move the wall outwardly into conforming contact with the inner wall surface of the mold to effect permanent reshaping of the workpiece into the desired configuration.

Abstract: 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.

Abstract: A method and apparatus for reshaping a container body (e.g., a metal, drawn and ironed container body) utilizing a floating mechanism for imparting an axial load is disclosed. In one embodiment, a container may have a substantially cylindrical sidewall with an inner surface and outer surface, where a shape defining means has a contoured surface positionable with respect to a container sidewall. When a floating mechanism imparts an axial load, a fluid seal is maintained allowing sidewall deformation by means of a directed pressurized fluid.

Abstract: The present invention provides an apparatus for shaping/embossing thin-walled work pieces, and is particularly apt for realizing complex and non-uniform shapes/designs in cylindrical metal container bodies. In one application, at least one pressurized fluid stream is ejected directly against one side of container body sidewall with a configured surface provided on the other side of the container body sidewall to achieve the desired shaping/embossing. At least one of the pressurized fluid stream and configured surface may be disposed for rotational and/or longitudinal motion. Such driven motion can be utilized to achieve progressive helical working of a cylindrical metal container body, thereby yielding the desired shaping/embossing.

Abstract: A method and apparatus for reshaping a container body (e.g., a metal, drawn and ironed container body) utilizing multiple fluids is disclosed. One fluid applies a generally low fluid pressure to the surface to be reshaped, while the other fluid applies a generally high fluid impact pressure to the surface to reform the same by changing its shape. In one embodiment, the interior of a drawn and ironed container body is pressurized with an appropriate gas (e.g., air) and a nozzle is introduced into the interior of the container body to apply a concentrated force to the interior surface of the container body with a high velocity liquid stream (e.g., water).
