Abstract
A collapsible carbonated beverage container is formed with a plurality of collapsible corrugations which allow collapse of the container. The corrugations include planar regions which provide a surface for attachment of a label, and which serve as a "hinge" about which the corrugations collapse after the contents have been removed. The structure of the corrugations provides axial stability to prevent flopping-over. After liquid is removed from the container, the container is axially collapsed and the top resealed, thereby preserving carbonation in the beverage.
