A plastic bottle having a substantially uniform side wall thickness yet having a sculptured appearance is formed generally symmetrically about a vertical axis. The bottle includes a base portion, a side wall portion extending upward from a lower margin united to the base portion to an upper margin, a shoulder portion extending from the upper margin of the side wall portion to a neck portion, and a finish portion united to the neck portion and adapted to receive a closure. At least one of the side wall and shoulder portions includes a plurality of generally vertical ribs spaced uniformly around a circumference of the bottle, each generally vertical rib having an upper and lower end and, in cross-section, a central portion situated at a first radius from the bottle axis and a pair of generally symmetric side portions leading to the bottle surface at a second radius from the bottle axis, at least one set of the upper and lower ends of the ribs terminating at a common height on the container. Only one of the upper and lower ends of the ribs on each portion of the bottle is joined together by a set of arcuate rib segments forming a scalloped line around the circumference of the bottle giving the appearance of a substantial variation in side wall thickness.
