at least one of before or during at least one of the cleaning or the coating the outer container surface of the glass container is contact-free or in contact with a material having a lower hardness than that of the glass container or only in contact with such materials.

9 . The method for processing the glass containers of claim 8 , wherein the cleaning is the first processing step and the coating is the second processing step.

10 . The method for processing the glass containers of claim 8 , wherein at least one of:

the cleaning of the glass containers comprises ultrasonic cleaning; or

the coating of glass containers comprises dipping the glass container into the coating material.

11 . The method for processing the glass containers of claim 10 , wherein the coating of the glass containers comprises dipping the glass containers first with the container bottom into the coating material and then further up to an upper limit.

12 . The method for processing the glass containers of claim 11 , wherein the upper limit is located in an area of the container shoulder.

13 . The method for processing the glass containers of claim 8 , wherein the coating material has one or more of the following properties:

(a) the coating material is a silicone emulsion with a silicone content between 0.4 and 7 percent by weight of the silicone emulsion or comprises such a silicone emulsion;

(b) the coating material also includes solvents;

(c) the coating material is formed such that it post-cures under the influence of temperature;

(d) the coating material at least one of is recommended by the German Federal Institute for Risk Assessment (BfR) for contact with foodstuffs and is approved as a medical product by the German Federal Office for Drugs and Medical Devices (BfArM);

(e) the coating material comprises a 35% dimethicone emulsion; or

(f) the coating material comprises a 35% dimethicone NF emulsion.

14 . The method for processing the glass containers of claim 8 , wherein after coating the glass containers, the coating is homogenized by removing or smoothing a drop of coating material formed at the container bottom, at least one of before or during the homogenization the outer container surface of the glass container is contact-free or in contact with a material having a lower hardness than that of the glass container or only in contact with such materials, and when homogenizing the coating, the plurality of glass containers is dipped into a solvent or advanced to a surface of a solvent or advanced to a smoothing device.

15 . The method for processing the glass containers of claim 14 , wherein at least one of:

at least one of before or during the homogenization the inner container surface of the glass container is contact-free; or

at least one of before or during the homogenization the container opening of the glass containers is sealingly closed in order to prevent substances from penetrating into the inner volume.

16 . The method for processing the glass containers of claim 8 , further comprising drying the coating material, wherein during the drying the outer container surface of the glass container is contact-free or in contact with a material having a lower hardness than that of the glass container or only in contact with such materials, and at least one of:
