<p>A valve with a fixed body and an internal socket has a tubular end that moves over the primary end of a cannula. An orifice on the tubular end is covered during emptying of a bottle until final inert gas injection. The orifice is opened during filling of the bottle to facilitate exit of nitrogen from the bottle, and during a leveling phase to facilitate the exit of excess fluid from the bottle.</p> |
