Abstract
A lock device for adding and removing containers to and from a vacuum treatment chamber, wherein the device comprises carrier plates for the containers, the plates being fastened to a revolving transport means and being transported through lock channels provided in straight sections of the transport means, achieving a sealing effect with said channels. The plates are moved past suction or ventilation openings in the lock channel. In this way, a differential pressure stage can be formed. The device can be flexibly dimensioned and cost-effectively produced.

- carrier plates arranged at the transport means at a distance (B) for holding the containers;
- lock channels at least partially extending along the straight sections through which the containers are transported by the transport means, and
- wherein the carrier plates are embodied such that they achieve such a sealing effect with the channel walls that a drop of pressure can be generated in the lock channels.
