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： 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： Methods and apparatus for redrawing a drawn cup are disclosed. In particular, the methods and apparatus disclosed are directed to redrawing a container body for use in a two piece beverage container. The redraw operation uses a redraw sleeve and a redraw ring that prevent wrinkles when a thin gauge metal is employed. The wrinkles are prevented by providing cooperating displacements on the surfaces of the redraw ring and the redraw sleeve that clamp the bottom surface of the cup that is being redrawn. This displacement provides a convoluted path through which the metal is pulled during the redraw operation to increase the resistance to being drawn and the tension in the side wall, thereby substantially eliminating wrinkles.
