Zusammenfassung:	A drawn and wall ironed beverage can body, method for forming same, and a sealed and filled can, include a through-hole or aperture in the base. A grommet for charging a propellant in can is located in the aperture. The aperture has a burr that is located on the inboard side of the rim of the aperture. A method of forming a valve in the drawn and ironed beverage can body includes positioning a first tool in an interior of the can body, contacting an exterior surface of the base with a second tool such that the first and second tools are aligned, forming the aperture in the base, and inserting the grommet into the aperture.
