ABSTRACT:
The purpose of this invention is to maintain a minimal air-liquid ratio in order to reduce cabonation losses in large, disposable beverage containers such as the plastic ones used to contain carbonated soft drinks. This is accomplished by reducing the volume within a collapsible, pressure-resistant bag within the container as the beverage is removed by sealing the bag at the air-liquid interface.
