ABSTRACT:
A plastic container that is designed for optimal strength and lightweighting characteristics includes a finish portion, a bottom portion that has a plurality of support feet and a corresponding number of grooves defined between the support feet, and a main body portion. According to one feature of the container, the main body portion has at least one groove defined in its smooth label area that is oriented so as to have an axial component and so as to extend to near a bottom of the label portion for permitting condensate to drain from the label portion. This reduces the potential for condensation-induced label delamination. According to another feature of the container, the main body portion further has a tapered neck portion that has a plurality of undulating grooves defined therein to provide structural reinforcement. The main body of the container also has a lower end that is configured so as to have a number of generally axially extending channels that extend toward the bottom portion. Some of these channels merge into the grooves, and others terminate before reaching the bottom portion. The channels provide a structural reinforcement effect, whereby enhanced structural reinforcement of said lower end is achieved without increasing the number of support feet and grooves.
