ABSTRACT:
A plastic flask (10) is embodied by a blow molded plastic container (12) including an upper neck (14), a convex front wall (24), a concave rear wall (26), curved side walls (28), a pair of shoulders (30) extending laterally outward from the neck, and chamfers (32) that connect the shoulders with the concave back wall and the pair of side walls. These chamfers (32) reduce the internal volume of the plastic container (12) so as to be generally the same as a glass flask of the same outer size and shape when viewed from a frontal direction. Each chamfer (32) preferably has an inclined upper end (34) that is planar and of a triangular shape. Each chamfer (32) also preferably includes a planar portion provided by a lower end (36) that extends downwardly in a vertical direction from the inclined upper end (34). The container (12) can be made by an injection-stretch blow molding process so as to be biaxially oriented or by extruding a hot plastic parison that is formed to include a compacted neck. While any suitable plastic can be used in either mode of manufacturing, polyethylene terephthalate is one plastic that has particular utility for holding alcoholic beverages.
