One embodiment of the invention relates to a container having a longitudinal axis and with a finish, shoulder, finish base, and a step. The shoulder has a wall thickness and is inclined away from the finish at a first angle with respect to a plane that is perpendicular to the longitudinal axis of the container. The a finish base extends from the bottom of the finish towards the shoulder and has a wall thickness The finish base is inclined away from the finish at a second angle with respect to a plane that is perpendicular to the longitudinal axis of the container. The step extends from the finish base to the shoulder and is inclined away from the finish at a third angle with respect to a plane that is perpendicular to the longitudinal axis of the container. The step also has longitudinal height that is approximately the same as the wall thickness of the finish base; and. The container further includes a tubular sidewall extending from the shoulder, in direction that is generally parallel to the longitudinal axis of the container, and the step improves material distribution in the finish base and shoulder to contribute to uniform cooling thereof, thus achieving the perpendicularity of the finish with respect to the longitudinal axis of the container.
