ABSTRACT:
A method and device for sterilizing containers in which a plasma treatment is executed through excitation of an electromagnetic oscillation so that the plasma is excited in a vacuum in the vicinity of the container regions to be sterilized. Between arrival and discharge, the container regions to be sterilized are moved closer to the oscillation-generating device in the chamber, with continuous movement of the container and/or of the oscillation-generating device for one or more predetermined time intervals in such a way that a plasma is excited in these regions inside and/or outside the container. The chamber is provided with a transport apparatus inside it, which produces an essentially rotating motion of the container during the transport from the arrival to the discharge in the chamber.
