PLASTIC CONTAINER WITH LOW PROFILE BASE

摘要

A plastic container (10) for packaging a liquid such as bottled water includes a finish portion (12), a main body (16), and a footed base (18) that possesses a unique low profile configuration that creates enough surface area in the base to adequatly minimize reaction stress forces that might occur from pressurization of the container (10), but that aesthetically minimizes the presence of the footed base (18). The base is unitary with a lower end of the main body and includes a plurality of support feet (20) at a bottom end thereof and a corresponding plurality of valleys that are positioned between adjacent support feet (20). The base further has a major height (HB) that is defined as the vertical distance between a lowermost extension (24) of the support feet and an uppermost point (26) of the base, and a major diameter DB that is defined as the diameter of the base at its point of maximum diameter. The low profile configuration of the base is defined as a ratio HB/DB that is within a range of about 0.05 to about 0.45.
