Blow nozzle to control liquid flow with pre-stretch rod assembly and metal seat seal pin

An apparatus for forming a container from a container preform, said apparatus comprising:

• a housing;
• a mold cavity;
• and
• a nozzle system disposed in said housing and operably connectable to the mold cavity, said nozzle system being positionable between a first position engaging said housing along an interface of contact preventing pressurized liquid from being injected into the container preform and a second position spaced apart from said housing permitting pressurized liquid to be injected into the container preform, said nozzle system having a tip portion, said tip portion being positionable within the container to displace a predetermined volume of liquid to define a predetermined head space with the container after filling.

An apparatus for forming a container, said apparatus comprising:

• a housing having a central bore;
• a stretch rod apparatus disposed in said housing, said stretch rod apparatus having a stretch rod extending through said central bore for at least partially forming a container preform;
• and
• a nozzle system disposed in said housing and operably coupled with said stretch rod apparatus, said nozzle system having a seal rod extending through said central bore being generally coaxial with said stretch rod, said nozzle system being positionable between a first position whereby a seal portion having a sealing surface engages a complementary surface of said housing thereby preventing pressurized liquid from being injected into the container preform and a second position permitting pressurized liquid to be injected into the container preform, said nozzle system including a seal portion having a first tapered surface, said first tapered surface engaging a second tapered surface extending from the housing in said first position.
