Apparatus for closing containers with contactless torque generation

An apparatus for treating containers, comprising a housing, inside which a sterile chamber is formed, comprising a treatment element for treating the containers, which treatment element is arranged inside the housing and is rotatable about a predefined axis, wherein the treatment element is arranged on a carrier provided inside the housing, and comprising a drive device for driving the treatment element, wherein this drive device is arranged at least partially outside the sterile chamber, wherein the drive device comprises at least a first drive element arranged outside the sterile chamber for generating rotational movements, and the treatment element is coupled to a second drive element for transmitting torques, said second drive element being arranged inside the sterile chamber and being rotatable about a predefined second axis of rotation, wherein the first drive element and the second drive element cooperate in a contactless manner in order to generate the rotational movement of the treatment element and are separated from one another by at least one wall, and wherein 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, wherein a sterile chamber boundary runs between the first drive element and the second drive element.
