Injection nozzle with finish cooling and counter pressure

An injection nozzle for receiving a finish of a preform and forming of a container from the preform by injecting of a liquid blow medium into the preform, the injection nozzle comprising:

• a central passageway defined through the injection nozzle and coupled to a source of liquid blow medium
• a nozzle body provided at one end of the injection nozzle, the nozzle body defining a receiving space adapted to receive the finish of the preform, the receiving space being coaxial with the central passageway and being configured for fluid communication therewith, the nozzle body defining a first sealing surface about the central passageway and adapted to engage an end surface of the preform;
• at least one inlet passageway defined through the nozzle body and communicating with the receiving space;
• the nozzle body being a manifold having a cavity defined therein, portions of the cavity being defined by an inner wall and an outer wall of the manifold, a plurality of ports defined through the inner wall and communicating the cavity with the receiving space, the at least one inlet passageway terminating in communication with the cavity;
• a source of cooling medium at a temperature less than the temperature of the finish of the preform, the source of cooling medium being in fluid communication with the inlet passageway;
• and
• wherein cooling medium received from the at least one inlet passageway into the cavity is directed through at least some of the ports toward the finish of the preform located within the receiving space to uniformly cool the finish of the preform.
