Abstract: A beverage container for a carbonated beverage includes a floating hollow insert (1) comprising an upper moulding (2) and a lower moulding (3) defining a chamber for containing gas, a first one-way duck-bill type valve (4) integrally formed with the upper moulding (2) at the bottom of a down pipe (6) and arranged to allow gas to enter the chamber and a second duckbill valve (5) integrally formed with the lower moulding (3) and arranged to allow gas to exit the chamber and be jetted into the beverage upon opening the beverage container.

Abstract: A system for pressurizing a dispensing container, such as a beverage dispensing container, may be in the form of a pressure pouch package which includes an outer pouch and an inner pouch. The inner pouch may be a pressure pouch having multiple compartments and components of an at least two component gas generating system contained within the compartments. The outer pouch may be sized so that it will not open when the pressure pouch is initially activated but will only open after a first quantity of product is dispensed from the dispensing container. In this manner, the outer pouch serves to maintain the folded configuration of the pressure pouch until after a first quantity of product is first dispensed from the container. This, in turn, prevents entrapment of the pressure pouch reactive components from occurring. The outer pouch also serves to prevent the pressure pouch from coming into contact with the product until after a first quantity of product is first dispensed from the container.
