    摘要： A method of manufacturing a metallic can body that is shaped distinctively in order to enhance its visual presentation to consumers includes, in one embodiment, steps of providing a can body blank that has a sidewall that is of a substantially constant diameter; providing a mold unit that has at least one mold wall that defines a mold cavity conforming a desired final shape of the can body; positioning the can body blank within the mold cavity; and supplying a pressurized fluid into the mold cavity so that the can body blank is forced by pressure against the mold wall, causing the can body blank to assume the desired final shape of the can body. Axial compression is preferably applied to the can body blank in order to reduce internal stresses during molding of the container. A second embodiment includes steps of radially deforming the can body blank in selected areas by selected amounts to achieve an intermediate can body that is radially modified, but is still symmetrical about its axis; and superimposing a preselected pattern of mechanical deformations that have an axial component onto the intermediate can body. Related apparatus and processes are also disclosed.

    摘要： This relates to the double seaming of an end unit to a metal can body where the end unit is of the full opening, easy opening type incorporating a pull tab for the purpose of initiating a rupture followed by pull out of an end panel of the end unit. Most specifically, the end unit is of an oblong rectangular or generally other than round outline so as to have a fixed orientation with respect to a double seam forming double seaming chuck. By having a fixed relationship between each end unit and the double seaming chuck and the pull tab with respect to the configuration of the end unit, it is possible to form a notch in the underside of the double seaming chuck to clear the pull tab. This permits the pull tab to have a force applying nose thereof positioned closely adjacent to a chuck wall of the end unit so that it may overlie a score line or weakening line formed in the chuck wall radius between the chuck wall and the end panel.
