Abstract

A method and apparatus for connecting a metal lid to a metal body of a container to sel any product held by the container. The container formed from a generally cylindrical body (12) having an upper edge (18) and a metal lid (16) having a peripheral edge (20). The metal lid is held in position on the body so that the upper edge of the metal body and the peripheral edge of the metal lid form a contiguous junction. A beam of laser energy is directed toward the contiguous junction for a sufficent time to hermetically seal the lid to the body. A single roll-formed lip provides a smooth finish to the combined body and lid. The lid includes a circumferentially continuous recess (24) surrounding a central planar portion (22) of the lid. The recess is located adjacent the peripheral edge while the peripheral edge is situated at or below the plane defined by the central planar portion, thereby reducing the material required to form a sealed container of any given volume.
