A method and apparatus to aseptically dispense liquid under counterpressure for filling thereof into a container. In a sterilization phase that precedes the filling, the inner surfaces of a container, the container mouth, as well as an outer surface of the container adjacent to the mouth thereof, are acted upon by a hot, pressurized, gaseous or vaporous sterilization medium. During both the sterilization and filling phases, the respective container is thereby completely disposed in a chamber in such a way that the interior of the container communicates via the mouth thereof with the interior of this chamber. The sterilization medium is introduced into the container at a distance from the mouth thereof via a filling tube that later serves for filling. At least during a portion of the sterilization phase, but also during the subsequent filling phase, the chamber is closed to the atmosphere in such a way that at least during this portion of the sterilization phase, a sterilization medium pressure that is greater than atmospheric pressure is set in the chamber, and during the filling phase the dispensing of the liquid into the respective container is effected against a counterpressure that exists within the chamber.

In a method of dispensing a liquid under counterpressure into a container, such as a bottle, in an aseptic or sterile manner, whereby said container that is to be filled is acted upon, at least during a portion of a sterilization phase that precedes a filling phase where said container is filled with said liquid, in a chamber that is adapted to be closed off to the atmosphere, by a hot, gaseous or vaporous sterilization medium that is under pressure, with this medium acting upon inner surfaces of said container that delimit the interior thereof, upon the mouth of said container, and also upon the outer surface of said container adjacent to said mouth thereof, with said chamber being disposed below a filling element that in said filling phase delivers said liquid into the interior of said container via a filling tube that extends through said mouth of said container and into the interior thereof, the improvement therewith comprising the steps of: during said sterilization phase as well as during said filling phase, accommodating said container enclosed completely in said chamber in such a way that said interior of said container communicates via said mouth thereof with said interior of said chamber; during said sterilization phase as well as during said filling phase accommodating said container completely in said chamber the interior of which communicates by the mouth of the container with the interior thereof; during said sterilization phase, introducing said sterilization medium via said filling tube and said exit thereof into said interior of said container, with said exit being positioned directly at the bottom of said container; and in said filling phase, with said chamber closed-off to the atmosphere, effecting dispensing said liquid from said exit into the container against a counterpressure that exists in said interior of said chamber after a desired filling state has been achieved in said container, supplying said sterilization medium to said filling tube to completely drain same into said bottle.
