Claims13
A method for manufacturing and filling a plastic container, comprising:
- introducing a preform into a blow mold;
- pressurizing the preform with a blowing medium to manufacture the plastic container;
- evacuating, with a filling nozzle engaged with a mouth of the plastic container forming a seal, an interior space of the plastic container to an underpressure, wherein a volume of the interior space remains substantially the same during the evacuating;
- and
- introducing, with the filling nozzle, a fill product into the evacuated interior space at an overpressure wherein, during the introducing, no fluid is displaced by the fill product and no fluid flows out of the interior space.
