Apparatus for blow molding aseptic containers

An apparatus for blow molding sealed aseptic containers, said apparatus comprising:

• a pair of mating mold halves including inner surfaces that when closed define a mold cavity;
• a first source of pressurized air connected to provide blow air to an interior of a parison located within the mold cavity so that supply of blow air to the interior of a hot resin parison captured within the cavity is effective to expand the parison to form a blow molded container conforming to the shape of the mold cavity;
• an evacuation device for applying force to the exterior of the blow molded container while the temperature thereof is above ambient temperature to deform the blow molded container to reduce the internal volume thereof and force a portion of pressurized air to be evacuated from the interior of the blow molded container, the amount of reduction of interior volume of the container effective to produce a sealed container that, at ambient temperature, that has the interior volume and shape defined by the mold cavity;
• and
• a sealing tool being movable between a first position and a second position, the sealing tool being moveable into the second position while the volume of the blow molded container is reduced by the evacuation device thereby sealing the blow molded container with the reduced internal volute to retain residual blow air therein.
