Abstract

Converting a cylindrical parison or preform closed at one end into a broad based tapered container by confining the preform in a wide mouthed cavity and introducing into the open end a conical mandrel which heats and spreads the preform to fit the cavity. The tip of the male mandrel should discharge a heated pressurised fluid during entry; the pressure trapped in the preform stiffens it to inhibit crumpling, while excess fluid escaping via the preform mouth lubricates the mandrel/preform interface.
