Zusammenfassung:A molded article (50) suitable for subsequent blow-molding into a final-shaped container. The article includes a neck portion (32); a gate portion (36); and a body portion (34) extending between the neck portion and the gate portion, at least a majority of the body portion having an overall shape which is symmetric about a body axis extending longitudinally through a center of the body portion. The body portion includes an inner exterior layer and an outer exterior layer of a first polymeric material; and a core layer of a second polymeric material disposed between the inner exterior layer and the outer exterior layer. A radial thickness or a material of the core layer is selectively varied to govern non-uniform blow molding of the molded article (50) into the final-shaped container.
