Apparatus for reshaping a container

An apparatus for reshaping a portion of a cylindrical side wall of a drawn and ironed container body, said cylindrical side wall having an initial mean average diameter comprising:

• a shaping mandrel connected to a housing, said shaping mandrel including a plurality of expanding forming segments, each of said expanding forming segments having a contacting surface for engaging an interior surface of said side wall of said drawn and ironed container body and expanding a portion of said side wall radially outward, said expanding forming segments moveable from a first collapsed position radially outward to a second engaging position, wherein when said expanding forming segments are moved radially outward to engage said interior surface of said side wall said expanding forming segments are circumferentially space apart to form gaps between each said expanding forming segment;
• and
• an external tool for engaging an outer surface of said side wall of said container body during a reshaping operation to apply a radially inward force to said side wall to create radially inwardly deformed segments in said expanded portion of said side wall of said container body, said external tool including a plurality of external forming segments, said external forming segment aligned to contact portions of said side wall of said container in said gaps between said expanding forming segments when in said second engaging position said expanding forming segments and said external forming segments working cooperatively to reshape said portion of said cylindrical side wall of said drawn and ironed container to have a first mean average diameter greater than said initial mean average diameter.
