Zusammenfassung:A reinforced plastic container having improved rim planarity. The container has a non-round main body portion integral with a finish portion. The main body portion has a central longitudinal axis and defines a hollow interior of the container. The finish portion has an upper surface defining a rim with a circumference framing a round opening that provides access to the hollow interior of the container, a radially outwardly extending snap bead being adapted to receive and retain a closure and hermetically seal the container and including interrupted portions located around the circumference of the rim, and a plurality of reinforcements located in the interrupted portions of the snap bead and assuring substantial planarity of the upper surface of the rim even when substantial forces act on the container. Each reinforcement has a strut bounded by and centered between a pair of strut indents, with each indent supported by a buttress.
