Method and Apparatus for Portable Beverage Containers that Preserve and Re-Carbonate Beverages Exposed to Atmosphere Air

Abstract

An apparatus that vents atmosphere air and allows for the pressurization of a sealed beverage container with carbon dioxide for the purpose of reducing oxidation and preserving or re-introducing effervescence to the beverage housed within the container. The previously mentioned apparatus can be integrated and/or retrofitted to accommodate the various sizes and shapes of current and future portable beverage containers. For the purpose of this apparatus, “portable beverage container” is defined as having a volume less than or equal to 5 gallons and the apparatus uses external or internally integrated pressure regulated gas sources to pressurize the container.

I claim: 
     
         1 . An apparatus and process that can be integrated into a portable beverage container, which allows for pressure regulated carbon dioxide gas to pressurize the beverage container and expel oxygen from the interior of the container for the purpose of preserving the effervescence and preventing oxidation to the contained beverage, comprising of:
 A) a pressure relief device to be installed at the apex of the portable beverage container that communicates with the interior of said container, and said pressure relief device is calibrated to ensure desired interior pressure is achieved and that oxygen is expelled from the container;   B) a valve that communicates with the interior of the portable beverage container that allows for an internally or externally, adjustable pressure regulated carbon dioxide source to pressurize the container at a pressure greater than the aforementioned calibrated pressure relief device, forcing the less dense oxygen gas out of the portable beverage container and pressurizing the head space of the portable beverage container with carbon dioxide gas.
