Abstract

A plasma processing plant for plastic bottles, having a vacuum chamber arranged inside the processing chamber and when a respective bottle opening is pressed against a valve, the valve will open and establish a connection between the interior of the bottle and the vacuum chamber, and the chambers are continuously sealed against one another in a gastight fashion. With such approach, the gas can be conducted more easily and the number of control mechanisms can be reduced.
