Abstract:
An arrangement for sterilizing inner surfaces as well as an area of outer surfaces, located at a filling opening, of pressure sensitive, non-electroconductive containers by means of a low-pressure plasma, comprising:an evacuable chamber for taking up the containers,a vacuum pump for evacuating the chamber,a supply pipe for supplying gas to be ionized, which pipe is connected to the chamber,two electrodes which surround the containers with shell-like areas, said electrodes generating the plasma, the electrodes having a recess in the area of the filling opening, said recess having clearance in relation to the container, anda high frequency generator for applying an alternating voltage at one of the electrodes, one of which is grounded,wherein the electrodes form the evacuable chamber in such a manner that surfaces of the electrodes facing away from a container being sterilized need not be evacuated.
