Estimating the term…
The present invention relates to a device for coating containers with a barrier layer having at least one plasma chamber, which encloses at least one treatment space, in which at least one container with a container interior can be inserted and can be positioned on the treatment space, wherein a gas lance is provided which can be introduced into the container interior and which further acts as microwave antenna, with the plasma chamber being designed to be capable at least of partial evacuation and being designed to fill the container interior at least partially with a plasma and a process gas. The device is designed such that the container can be preheated by means of a plasma, more particularly by means of a microwave plasma, using a noble gas which can be introduced into the container interior through the gas lance.
A device for coating containers with a barrier layer having at least one plasma chamber, which includes at least one treatment space, and in which at least one container with a container interior can be inserted and positioned on the treatment space, wherein a gas lance is present which can be introduced into the container interior and which furthermore acts as microwave antenna, wherein the plasma chamber is formed to be capable of at least partial evacuation and is set up to fill the container interior at least partially with a plasma and a process gas, wherein the device is formed such that a pre-heating of the container can be carried out by means of a plasma, in particular by means of a microwave plasma, using a noble gas which can be introduced into the container interior via the gas lance.
