Container preform and forming/filling nozzle each configured to provide a seal therebetween

A system for simultaneously forming a container and filling the container with a product, the system comprising:

• a thermoplastic preform configured to be molded into the container, the thermoplastic preform including a finish comprising:
• a brim defining an opening;
• threads at an outer surface, the threads configured to cooperate with a closure;
• a sealing ledge at an inner surface, the inner surface is opposite to the outer surface;
• and
• an inner sealing sidewall extending between the sealing ledge and the brim;
• a nozzle for a forming/filling head configured to inject the product into the thermoplastic preform sealed to the nozzle for simultaneously forming the container from the thermoplastic preform and filling the container with the product, the nozzle comprising:
• an outer flange at an outlet of the nozzle;
• an inner flange surrounded by the outer flange, the inner flange including an outer sealing surface facing the outer flange, an inner surface opposite to the outer surface, and a lower sealing surface;
• and
• an upper sealing surface between the outer flange and the inner flange;
• wherein upon insertion of the finish between the outer flange and the inner flange of the nozzle, the finish seals to the nozzle through cooperation between:
• the brim and the upper sealing surface of the nozzle between the outer flange and the inner flange;
• the sealing ledge of the finish and the lower sealing surface of the inner flange of the nozzle;
• and the inner sealing sidewall of the finish and the outer sealing surface of the inner flange of the nozzle.
