An improved liquid filling valve for filling containers with carbonated liquid such as soft drinks is disclosed which features concentric valves for introduction of counterpressure gas and product into the container. The container is moved into sealing engagement with the valve which movement is continued to open the valve for admission of counterpressure gas. After counterpressurization is completed the valve for admission of product opens automatically allowing product to fill the container. After filling is completed, motion of the container away from the valve automatically closes it. In the bottle filling embodiment, motion of the bottle away from the valve additionally uncovers a snift port. The counterpressure filling and snifting of containers with carbonated liquids is thus accomplished without use of external valve operating cams or the like.

Apparatus for the counterpressure filling of a container with a pressurized carbonated liquid comprising: a first valve member; means for moving said container to sealably engage the mouth of the container with said first movable valve member and to move said first movable valve member to admit counterpressure gas into said container; a second valve member in communication with a reservoir of said pressurized liquid and normally held closed by the pressure of the liquid thereon and biased to open when the counterpressure within said container is substantially equal to the pressure of said carbonated liquid, whereby said second valve member opens after said container is counterpressurized, to admit said carbonated liquid into said container; and means for terminating flow of said carbonated liquid into said container at a predetermined point, wherein said means for moving said container relative to said valve member additionally removes said container from said valve means after termination of flow of said carbonated liquid into said container and closes said first and second valves.
