Abstract
An improved plastic container of the type suitable for containing carbonated beverages. The container is provided with a central section, an upper section including a typically threaded neck portion, and a lower end or base section typically including radially arrayed concave foot portions to support the container in an upright position. The horizontal cross-section of the central section manifests the configuration thereof to include a plurality of juxtaposed generally flat panels which upon pressurization of the container tend to blend together to form a circular cross-sectional configuration.
