Abstract: A nozzle is provided for engaging with lightweight preforms for blow-molding the preforms into plastic containers without damaging the finish portion of the preforms. The nozzle includes a seal configured to engage with a stepped interior of the finish portion and enables stretching and/or blow-molding the preform into a container. The seal tightly engages a smooth surface inside the finish portion without damaging the surface or a sidewall of the finish portion. In some embodiments, the seal includes a profile shape that mates with a transitional surface comprising the stepped interior of the finish portion. The profile shape distributes the contact force of the seal over a maximal area of the transition surface so as to minimize the total pressure exerted onto the finish portion. The profile shape reduces potential cracking of a thin-walled region of the finish portion during stretching and/or blow-molding the preform to form the container.
