FULLY PREPARED PLASTIC VESSEL FOR AERATED DRINKS

摘要

A one-piece plastic container for carbonated beverages with a footed base structure (7) to support the container in an upright position. The container is manufactured with a reduced amount of plastic material while maintaining performance, particularly stability. Stability is preserved when the container is empty and when filled. The upper portion of the base structure has a strap formation (17) between each circumferentially adjacent pair of feet (35) that is relatively stiff and which communicate at their outer ends with readily deformable areas (15). When the container is pressurized from the carbonated beverage the areas (15) easily deform and expand to avoid unwanted distortions that commonly occur in other footed container base structures and cause the strap formations (17) to apply an upwardly directed force to the central region (14) of the base structure.
