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. Accordingly, the necessary gas barrier properties may be shifted from the pressure pouch to the outer pouch, which has a relatively simpler structure.
