Abstract
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.
