ABSTRACT:
The invention relates to deformable beverage containers for minimizing empty space in the container, to which CO.sub.2 can escape, and for increasing pressure in the container for stopping evaporation of CO.sub.2 from the beverage. With the container cap off or loose, the deformable portion of the container is compressed until the beverage reaches the top of the container. The cap is then secured and further compression applied until a desired pressure is reached. One embodiment covers regular bottles with a special bottle cap, comprising a check valve connected to inflatable bladder, and valve/spout arrangement for dispensing the beverage without opening the bottle. Another embodiment covers special internally deformable containers to which the beverage is transferred for preservation. A third embodiment covers plastic bottles with an external compressing mechanism for deforming the bottle and increasing pressure for maintaining the beverage during further storage.
