A method and apparatus is disclosed for purging air from containers, such as pouches, while in the ambient atmosphere, which apparatus uses a continuous flow of a neutral purging gas at a pressure between a range of about 1″-2″of water that is directed into the open end of the container through a flow control valve having a flat surface overlapping the open end of the container and disposed substantially parallel to and within about ⅛th inch from the open end of the container.

A flow control apparatus for purging air from a product filled container when one end of the container is open, said apparatus comprising a flow control valve having an apertured flat flow control surface positioned adjacent said open end of the container to overlap the open end while being spaced about ⅛th of an inch therefrom, and means for directing a neutral air purging gas at a pressure of between about 1-2 inches of water through said aperture into the open end of the container for creating a gentle non-turbulent flow of air and other gases out of the container along an unobstructed balanced flow path defined between the periphery of the open end of the container and said flat flow control surface.
