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.

First claim

The invention claimed is:

1. Apparatus for treating containers, having a housing, inside which a sterile chamber is formed, and 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 rotationally driving the carrier on which the treatment element is arranged, wherein the 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 a second drive element for applying a torque to the treatment element via the carrier to rotate the treatment element, the carrier on which the treatment element is arranged being coupled to said second drive element, said second drive element being arranged inside the sterile chamber and being rotatable about a predefined 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 carrier 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.

2. The apparatus according to claim 1 , wherein the treatment element is coupled to the second drive element via the carrier.

3. The apparatus according to claim 1 , wherein the apparatus comprises a plurality of treatment elements which are arranged on the carrier.

4. The apparatus according to claim 1 , wherein the second drive element is arranged such that it cannot move in the direction of the axis of rotation of the carrier.

5. The apparatus according to claim 1 , wherein the treatment element is a gripping clamp which is designed to hold the container.

6. The apparatus according to claim 1 , wherein the carrier is a transport wheel.

7. The apparatus according to claim 1 , wherein the second drive element comprises a plurality of permanent magnets.

8. The apparatus according to claim 7 , wherein the permanent magnets are arranged with alternating polarities in a circumferential direction around the second drive element axis of rotation.

9. The apparatus according to claim 7 , wherein a rotatable shall body is provided, on which the first drive elements is arranged.

10. The apparatus according to claim 1 , wherein the first drive element is arranged inside the second drive element in relation to the axis of rotation of the carrier.

11. The apparatus according to claim 1 , wherein a water lock is provided to seal the sterile chamber.

12. The apparatus according to claim 1 , wherein the first drive element is arranged geometrically inside the housing but outside the sterile chamber.

13. The apparatus according to claim 1 , wherein the second drive element comprises a rotatable sleeve.

14. The apparatus according to claim 1 , wherein a sleeve shaped body is arranged between the first drive element and the second drive element.

15. The apparatus according to claim 14 , wherein the sleeve shaped body delimits the sterile chamber.

16. The apparatus according to claim 14 , wherein the sleeve shaped body is arranged in a stationary manner.

17. The apparatus according to claim 1 , wherein the apparatus comprises an anchoring of the carrier, which is arranged inside the chamber.

18. Apparatus for treating containers, having a housing, inside which a sterile chamber is formed, and 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 in the form of a transport wheel provided inside the housing, and comprising a drive device for rotationally driving the carrier on which the treatment element is arranged, around a predefined axis of rotation, wherein this drive device is arranged at least partially outside the sterile chamber, characterised in that the drive device comprises at least a first drive element arranged outside the sterile chamber for generating rotational movements, and the carrier on which the treatment element is arranged is coupled to a second drive element for transmitting torques, said second drive element being arranged inside the sterile chamber and being rotatable about said predefined 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 carrier and are separated from one another by at least one wall, wherein the drive elements in each case have at least one magnetisable element, wherein the treatment element is arranged on an outer circumference of the carrier, and wherein the treatment elements is spaced apart from said predefined axis of the carrier in a direction perpendicular to said predefined axis by arranging the treatment element on said outer circumference of the carrier.

19. Apparatus for treating containers, having a housing, inside which a sterile chamber is formed, and 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 rotationally driving the carrier on which the treatment element is arranged, 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 a second drive element for applying a torque to the treatment element via the carrier to rotate the treatment element, the carrier on which the treatment element is arranged being coupled to said second drive element, said second drive element being arranged inside the sterile chamber and being rotatable about a predefined 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 carrier and are separated from one another by at least one wall, wherein the second drive element is arranged such that it cannot move in the direction of the axis of rotation of the carrier, and wherein the drive elements in each case have at least one magnetisable element.
