A plastic container including an upper end having an aperture defining an opening of the container. A lower end defines a base of the container. A sidewall portion merges into a grip portion and extends between the upper end and the lower end. The sidewall portion and the grip portion each include a plurality of horizontal ribs. The horizontal ribs of the sidewall portion each include at least one chamfered rib that provides additional structural strength and support to the container during hot fill, packaging and shipping operations.

A process and a bottle made from this process where the bottle has improved material thickness distribution within the bottom or base portion. The bottle has a noncircular cross-sectional configuration with corresponding major and minor axes. The mold-base region of the bottle mold-cavity features at least one standing rib-like projection generally parallel to the major axis. The standing rib-like projection increases surface distance in a direction generally corresponding with the minor axis. An expanding heated preform traverses the increased surface distance causing the preform to thin more than what otherwise would be the case thus improving material thickness distribution of the base portion that in turn minimizes unwanted bottle shape distortions.

A plastic container is provided having an elongated neck, a shoulder region, a body portion and a base. The shoulder region having a substantially square cross section. The base having a substantially circular cross section. The substantially square cross section of the shoulder region preserves the brand identification benefits associated with a square shaped container while the substantially circular cross section of the base preserves the handling and structural attributes associated with a circular shaped container.

A machine and method for blow molding a polyester bottle for carbonated beverages with an internal web structure positioned between two hand-grip depressions. The machine and method uses an injection-molded preform having a web feature and maintains the web of the preform in a precise position during heat-treatment and eventual blow molding into the bottle. Heat-treatment involves an oven capable of heating and cooling selected regions of the preform by using a combination of shields, heat energy reflective surfaces, and cooling airflows. Bottle blow molding involves precise placement of the preform relative to hand-grip surfaces in a blow mold cavity and cooling airflow of the internal web structure before bottle removal.
