Blow molding machine for producing pasteurizable containers

A blow molding machine for producing a heat set container, said machine comprising:

• a blow mold defining a mold cavity capable of receiving a preform;
• a high-pressure gas source to supply a high-pressure gas;
• a high-temperature gas source to supply a high-temperature gas;
• a fluid source to supply a fluid, said fluid in a liquid state and at ambient temperature and pressure;
• a mixer coupled to said high-temperature gas source and to said fluid source to mix the high-temperature gas with the fluid;
• a blow core assembly engagable with the preform and coupled to said high-pressure gas source, to said high-temperature gas source, and to said fluid source, said blow core assembly also having an exhaust;
• and
• a controller coupled to said high-pressure gas source, to said high-temperature gas source, and to said fluid source, whereby said controller controls the providing of the high-pressure gas into the preform to blow mold the preform into a container, and controls the mixing of the fluid with the high-pressure gas into a mixture such that the heat transfer coefficient of the mixture is greater than the heat transfer coefficient of the high-temperature gas alone, and controls the providing of the mixture to an interior portion of the container to induce crystallinity into the container, and controls the exhausting of the mixture through said exhaust.
