Abstract

A process for producing a metal can, having a cylindrical body, a base and a lid, of the type in which the base has a cylindrical recess which projects into the inside of the can, in which process: a) a combination of a body and a base is produced, by deep-drawing and wall stretching, from metallic and/or plastic-coated metal sheet which is suitable for cans; b) an insert piece, which is tubular in shape so as to correspond to the cylindrical recess and is closed on one side, is produced from corresponding metal sheet by deep-drawing or spinning, followed by wall stretching; c) a hole which is narrower than the open side of the insert piece is made in the base of the body-base combination; d) the edge of the hole is flanged until it acquires a bearing surface which is able to fit together with the edge of the open side of the insert piece; c) the edge of the hole and the edge of the open side of the insert piece are joined together.
