A system for forming a container from a preform includes a first mold operable to receive the preform and operable to blow mold a first form of the container from the preform. The system also includes a second mold operable to receive the first form and operable to blow mold a second form of the container from the first form. The preform, the first form, and the second form each include a substantially common transitional wall. Also, the first form can include various features that ensure that material will be distributed as desired throughout the container, to ensure high wall strength, and to ensure high crystallinity.
