    摘要: An injection nozzle for cooling and providing counter pressure to a neck of a preform during a forming of a container from the preform. The injection nozzle includes a manifold that defines a receiving space into which the neck of the preform is received. A cavity is also defined in a part by an inner wall and an outer wall of the manifold and a plurality of ports are provided through the inner wall to communicate the cavity with the receiving space. When a cooling medium is received into the cavity, the cooling medium is directed through at least some of the ports toward the neck of the preform located within the receiving space.
