Abstract

A device and method for centering a container during travel into a processing region, wherein the device has: a receiving section configured to receive the container; a guiding section configured to guide a translational movement along a defined trajectory between a receiving position and a processing position; a chamber wall having an opening, wherein the receiving section and the guiding section are configured to insert at least some section of the container into the processing region; a sealing device having an inflatable seal, which is arranged in the opening and configured to adopt a sealing position around a container section in the processing position; and a control device, which is in communication with the sealing device and is configured to at least partially inflate the inflatable seal during the translational movement of the container from the receiving position into the processing position.

First claim

What is claimed is:

1. A device for centering a container during travel thereof into a processing region, comprising:
a receiving section configured to receive the container;
a guiding section configured to guide a translational movement of the receiving section along a defined trajectory between a receiving position for reception of the container by the receiving section and a processing position for processing the container in the processing region;
a chamber wall having an opening, wherein the receiving section and the guiding section are configured to guide a section of the container into the processing region through the opening during the translational movement from the receiving position into the processing position;
a sealing device having an inflatable seal that is arranged in the opening and configured to adopt a sealing position around the container in the processing position; and
a control device in communication with the sealing device and configured to at least partially inflate the inflatable seal during the translational movement of the container from the receiving position into the processing position.

2. The device of claim 1 , wherein the control device is configured to partially inflate the inflatable seal during the translational movement of the container from a position in which a part of the container has already been inserted into the processing region through the opening into the processing position.

3. The device of claim 2 , wherein the part of the container that has already been inserted into the processing region comprises a mouth section of the container.

4. The device of claim 1 , wherein the sealing device comprises a pressure medium supply in communication with the control device, and the pressure medium supply is configured to feed a pressure medium to the inflatable seal to inflate the inflatable seal.

5. The device of claim 4 , wherein the pressure medium comprises compressed air.

6. The device of claim 1 , wherein the guiding section is attached to the chamber wall.

7. The device of claim 1 , wherein the receiving section has a contour that tapers conically in a travel direction of the container and/or has a clamp shape with two clamp arms.

8. The device of claim 7 , wherein the receiving section has the clamp shape with the two clamp arms and the two clamp arms form an open ring.

9. The device of claim 1 , wherein the receiving section comprises a transport section that interacts with the guiding section in such a way that the receiving section is movable translationally along the defined trajectory.

10. The device of claim 9 , wherein the defined trajectory comprises a rectilinear trajectory.

11. The device of claim 9 , wherein the transport section has an opening through which the guiding section at least partially passes, to enable the receiving section to be moved along the guiding section.

12. The device of claim 9 , wherein the transport section has two openings and the guiding section has two associated guide rods that correspondingly pass through the two openings.

13. The device of claim 1 , wherein the receiving section is preloaded into the receiving position.

14. The device of claim 13 , wherein the receiving section is preloaded into the receiving position by one or more springs.

15. A device for processing a container, which comprises:
the device of claim 1 ; and
a processing chamber having the chamber wall, which defines the processing region, wherein the processing chamber is configured to be sealed off from an external environment.

16. The device of claim 15 , wherein the processing chamber is further configured to hold an excess pressure and/or a vacuum when the container is located at the processing position.
