Abstract
This invention is directed to a method and an apparatus for carrying out that method of transferring an unsealed container of a liquid containing dissolved gas from a filling station to a sealing station where a closure is applied while avoiding foaming and frothing of liquid from the container and the attendant loss of liquid by subjecting the container and contents during such transfer to an ambient super atmospheric pressure.
Claims6
A method of preventing foaming and frothing of a liquid containing a gas during the introduction into and sealing of a container therefor which comprises providing a pressure tight compartment, filling a container with a liquid containing a gas at a super atmospheric pressure sufficient to substantially prevent gas bubble nucleation at a filling station within said compartment, establishing and maintaining an ambient super atmospheric pressure in the compartment substantially as great as the gas pressure in the liquid, removing the filled container from the filling station in the presence of the ambient super atmospheric pressure in the compartment which acts to substantially prevent gas bubble nucleation in the liquid, transporting the filled container from the filling station to a sealing station while maintaining the super atmospheric pressure on the liquid contents, applying a closure to the container and sealing and closing the container while under said super atmospheric pressure.
