Abstract
An improved stretch rod tip having a hollowed area for receipt of a portion of a preform and at least a portion of a sprue during stretch blow molding of a container. Upon hardening of the container, the received portion of the preform becomes a protective dome over the received portion of the sprue that is at least partially internal to the container and that greatly reduces cracking, shearing, or other fracturing of the container due to a drop impact.
