Centering a container for the processing thereof

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.
