Abstract

Disinfecting a surface of packaging includes breaking up one of an outer covering and a membrane of germs on the surface, and applying carbon dioxide to the surface. Breaking up the outer covering or membrane is carried out by one or more of applying bactericidal energy, illuminating with UV radiation, illuminating with ultrasonic radiation, applying a bactericidal treatment medium, and applying a chlorine compound.

First claim

Having described the invention, and a preferred embodiment thereof, what is claimed as new, and secured by Letters Patent is:

1. A method comprising disinfecting a surface of packaging, wherein said surface is selected from the group consisting of a product-critical surface and a filling contents-critical surface, wherein disinfecting said surface comprises executing a first step and executing a second step, wherein executing said first step comprises breaking up one of an outer covering and a membrane of germs on said surface by applying a chlorine compound at a first dosage, and wherein executing said second step comprises applying, to said surface, a disinfection agent that comprises carbon dioxide and said chlorine compound, wherein said chlorine compound in said second step is applied at a second dosage that is less than said first dosage.

2. The method of claim 1 , wherein said disinfection agent is applied in liquid form.

3. The method of claim 1 , wherein said disinfection agent is applied in gas form.

4. The method of claim 1 , wherein said disinfection agent is applied in aqueous form.

5. The method of claim 1 , wherein the step of executing said first step comprises, in addition to applying a chlorine compound at a first dosage, illuminating said surface with flashes of UV radiation.

6. The method of claim 1 , wherein said second step comprises applying carbon dioxide at a first pressure above ambient pressure and reducing said first pressure to ambient pressure after said carbon dioxide has been applied to said surface.

7. The method of claim 1 , wherein the step of executing said first step comprises applying chlorine dioxide at a first dosage.

8. The method of claim 1 , further comprising executing said second step only after having executed said first step.

9. The method of claim 1 , further comprising beginning execution of said second step before completion of said first step.

10. The method of claim 1 , wherein the step of breaking up said one of an outer covering and a membrane of germs on said surface further comprises illuminating with UV radiation.

11. The method of claim 1 , wherein the step of breaking up said one of an outer covering and a membrane of germs on said surface further comprises illuminating with ultrasonic radiation.

12. The method of claim 1 , wherein said chlorine compound comprises chlorine dioxide.
