A method is described for sterilizing, filling and closing packaging containers open on one side, in which the packaging container is exposed to a sterilizing agent during a clock-controlled transportation in a processing line through different processing stations, which is then removed with sterile hot air. Then, the packaging container is filled with sterile fluid and with a sterile closure. In order for sterilizing and also sterile filling and closure to be implemented without an expensive clean room and in a technically simple manner, it is provided according to the invention that during sterilizing the respective fluid is introduced through the center of the aperture of each individual packaging container in the respective processing station under pressure above atmospheric, approximately as far as in the area between the center and the base of the packaging container, or possibly as far as its base, wherein the fluid is deflected in the interior of the package towards the aperture and is pressed out of this such that a first part of the exiting fluid is suctioned out of the surroundings of the aperture and a second part is allowed to leave in the space around the aperture of the packaging container.

1. A method for sterilizing, filling and closing at least one packaging container open on one side, comprising the steps of:a) transporting a packaging container along a time-controlled processing line; b) sterilizing the packaging container with a sterilizing agent, wherein the sterilizing agent is blown under a pressure above atmospheric pressure through an aperture of the packaging container into the packaging container, the sterilizing agent entering the packaging container flowing up to, and including, a central portion or a base or an area in between the central portion and the base of the packaging container, being deflected in an interior of the packaging container towards the aperture of the packaging container, and being removed and pressed out of the container whereby, a first exiting portion of the sterilizing agent is formed and removed from an area surrounding the aperture of the container whereby the first exiting portion is removed out of the aperture of the container, and a second exiting portion of the sterilizing agent exits through a space proximate the aperture of the packaging container; c) drying the packaging container with sterile air; d) filling the packaging container with a sterile product; and e) applying a sterile closure to the packaging container.
