ABSTRACT:
A preform carrier adapted to be received in the open end of a wide mouth tubular container preform for internally gripping the preform to permit carrying the preform from a heating station to a container blowing station. The carrier includes a flexible annular gripping member in the form of a gripping and sealing ring that is resiliently flexible in a radial direction, relative to the preform axis, for engaging the inner surface of the preform finish. The gripping member includes an annular sealing ridge on its outermost surface for gripping and sealing against the inner surface of the preform finish. The gripping member is of generally U-shaped configuration, and includes an inner annular U-shaped spring for urging the legs of the sealing ring outwardly to provide a gripping and sealing force against the inner surface of the preform finish.
