The closure head having at least one conduit providing fluid communication between the interior volume and at least one of a vacuum source and a pressure source. The method also includes creating at least a partial vacuum inside the container, inserting a replacement atmosphere into the container by means of the pressure source, sealing the container; and removing the closure head from the container.
