Abstract
A one-piece plastic container includes a body defining a longitudinal axis and having an upper portion, a sidewall portion and a base portion. The base portion defines a plurality of feet extending therearound. The base portion defines a contact diameter ratio of approximately 70-74% and a contact length ratio of approximately 20-23% for a plastic container having a volume capacity of approximately one (1) liter (1000 cc). According to additional features, the one-piece plastic container can have a nub defined on the base portion. For a one-piece plastic container having a volume capacity of approximately one (1) liter (1000 cc), the nub has a diameter of approximately 3-7 mm (0.12-0.28 inch), the base portion defines a contact area ratio of approximately 23-25%, and each foot defines corner transition portions each having a fillet radius of approximately 4-10 mm (0.16-0.39 inch).
