Abstract: Method and apparatus for producing a novel one piece, unitary, seamless can body with a reduced diameter opening for receiving an aerosol device or other small diameter closure. A truncated conical configuration portion is formed from sidewall metal in a sequence of operations in which an extended-length reduced-diameter neck is formed with a curvilinear transition zone leading to the main body sidewall portion. A portion of this reduced diameter neck is then further reduced in diameter, and this sequence continued, until the desired size opening is achieved and flanging metal provided for an aerosol device or other small diameter closure. Selection of dimensional parameters and percentage reductions provides for: smooth transition to smaller diameters, maintaining circular configuration, ease of removal of dies permitting operations from one longitudinal end of a can body, and maintaining substantially the original can body height.

Abstract: By predetermined selection of tin coating weight in the manufacture of electrolytically tinplated continuous steel strip, cup formation of sheet metal blanks cut from such tinplated flat rolled steel with the selected tin coating weight disposed internally, selective reduction of sidewall gage and coating weight, maintenance of tin coating weight on the interior surface of the bottom wall, and selective organic coating, the present invention enables production of special container packs, previously limited to three-piece containers, from unitary seamless can bodies. Selected tin coating weight on the interior surface of the bottom wall of the can body is maintained throughout the manufacturing process and this surface is exposed to container contents. The sidewall interior surface of the can body is protected from exposure to container contents by an organic coating.
