Abstract

An apparatus for treating containers includes a housing, inside which a sterile chamber is formed. A treatment element is arranged inside the housing and is rotatable about a predefined axis. The treatment element is arranged on a carrier inside the housing, and has a drive device for driving the treatment element. The drive device is arranged at least partially outside the sterile chamber and includes at least a first drive element arranged outside the sterile chamber for generating rotational movements, and a second drive element arranged inside the sterile chamber. The first drive element and the second drive element cooperate in a contactless manner to generate rotational movement of the treatment element. The drive elements in each case have at least one magnetisable element and preferably at least the second drive element is displaceable in the direction of its axis of rotation relative to the sterile chamber.
