Container

A dual convex flask is of one-piece integrally molded plastic construction. The flask has opposed front and back walls each with a convex label panel area at a first radius of curvature and axially spaced bumpers that extend outwardly from opposite ends of the panel area. Opposed substantially flat sidewalls connect adjacent side edges of the front and back walls. The bumpers on each of the front and back walls have a second radius of curvature that is greater than the first radius of curvature, such that the bumpers have a radial depth perpendicular to the label panel area which is greatest at the ends of the bumpers adjacent to the sidewalls and least at the center of the panel area.

Molded plastic flask

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.
