ABSTRACT:
A method for replenishing carbon dioxide gas in a carbonated beverage container where a carbon dioxide regulator releases carbon dioxide at a rate approximately equal to the rate of carbon dioxide loss from said container. Also shown is a packaging system for maintaining a consistent pressure of a carbonated beverage having a closure, a plastic container, and a carbon dioxide regulator. Also shown is a method for making a packaging system for maintaining a consistent pressure in a carbonated beverage having overmolding a preform around an assembly for a carbon dioxide regulator, or blending a carbon dioxide regulator into the plastic material used to form the body of a container for said carbonated beverage. Also shown is a carbon dioxide regulator composition for replenishing carbon dioxide gas in a carbonated beverage container having polymeric carbonates, organic carbonates, or materials that absorb and subsequently release carbon dioxide.
