Method for filling food containers

1. A method for filling beverage cans, which are eventually closed gas-tight and have an inner pressure that is above ambient pressure for stabilizing a beverage can including the steps:

providing the beverage can with an open filling orifice in a filling station;

filling the beverage can in the filling station;

covering the filling orifice of the beverage can with a lid directly after completing the filling process;

fixating the lid at the beverage can without closing the beverage can gas-tight; and

transporting the beverage can with the filling opening covered;

wherein the filling opening of the beverage can is covered by the lid which is eventually provided for permanent gas-tight closure of the beverage can, wherein the lid after filling in the filling station is only fixated but not permanently closed;

wherein the lid is pressed onto the beverage can from above and in a direction substantially parallel to the longitudinal axis of the beverage can;

wherein the lid is provided with an edge width inner diameter which is slightly smaller than a flange outer diameter of the beverage can; and

wherein the lid is snap-locked onto the respective beverage can.

2. The method according to claim 1 , wherein the beverage can is transported with a covered filling opening from the filling station to a closing station and closed in the closing station permanently gas-tight.

3. The method according to claim 1 , wherein the lid is fixated at the beverage can directly after filling or directly after the filling station so that gas can move outward from the covered beverage can.

4. The method according to claim 2 , wherein the lid and the beverage can are connected permanently gas-tight with one another in the closing station through folding or border crimping.

5. The method according to claim 1 , wherein the lid for covering the beverage can is supplied to the beverage can under an inert gas atmosphere.

6. The method according to claim 1 , wherein the beverage can is filled with a beverage that includes carbonation.

7. The method according to claim 1 , wherein the beverage can is filled with a liquid food and an inert gas.

8. The method according to claim 7 , wherein the gas is filled into the beverage can in liquid or solid form.

9. The method according to claim 2 , wherein the beverage can is moved to the filling station on a circular path and moved on a tangent to the circular path to the closing station after being filled in the filling station.

10. A method for filling beverage cans, which are eventually closed gas-tight and have an inner pressure that is above ambient pressure for stabilizing a beverage can including the steps:

providing the beverage can with an open filling orifice in a filling station;

filling the beverage can in the filling station;

covering the filling orifice of the beverage can with a lid directly after completing the filling process;

fixating the lid at the beverage can without closing the beverage can gas-tight; and

transporting the beverage can with the filling opening covered;

wherein the filling opening of the beverage can is covered by the lid which is eventually provided for permanent gas-tight closure of the beverage can, wherein the lid after filling in the filling station is only fixated but not permanently closed;

wherein the lid is pressed onto the beverage can from above and in a direction substantially parallel to the longitudinal axis of the beverage can;

wherein the lid comprises an edge width inner diameter which initially has the same size as the flange outer diameter of the beverage can or which is slightly larger than a respective beverage can; and

wherein the lid is slightly deformed during pressing onto the beverage can so that its edge width inner diameter as a consequence is smaller than the flange outer diameter of the respective beverage can.

11. The method according to claim 10 , wherein the beverage can is transported with a covered filling opening from the filling station to a closing station and closed in the closing station permanently gas-tight.

12. The method according to claim 10 , wherein the lid is fixated at the beverage can directly after filling or directly after the filling station so that gas can move outward from the covered beverage can.

13. The method according to claim 11 , wherein the lid and the beverage can are connected permanently gas-tight with one another in the closing station through folding or border crimping.

14. The method according to claim 10 , wherein the lid is supplied to the beverage can under an inert gas atmosphere.

15. The method according to claim 10 , wherein the beverage can is filled with a beverage that includes carbonation.

16. The method according to claim 10 , wherein the beverage can is filled with a liquid food and an inert gas.

17. The method according to claim 16 , wherein the gas is filled into the beverage can in liquid or solid form.

18. The method according to claim 11 , wherein the beverage can is moved to the filling station on a circular path and moved on a tangent to the circular path to the closing station after being filled in the filling station.

19. A method for filling beverage cans, which are eventually closed gas-tight and have an inner pressure that is above ambient pressure for stabilizing a beverage can including the steps:

providing the beverage can with an open filling orifice in a filling station;

filling the beverage can in the filling station;

covering the filling orifice of the beverage can with a lid directly after completing the filling process;

fixating the lid at the beverage can without closing the food container gas-tight; and

transporting the beverage can with the filling opening covered;

wherein the filling opening of the beverage can is covered by the lid which is eventually provided for permanent gas-tight closure of the beverage can, wherein the lid after filling in the filling station is only fixated but not permanently closed;

wherein the lid is pressed onto the beverage can from above and in a direction substantially parallel to the longitudinal axis of the beverage can;

wherein the lid is provided which has an outer diameter in a portion of its core bevel, wherein the outer diameter is greater than an opening inner diameter D i of a respective beverage can; and

the lid is placed onto a respective filled beverage can so that the lid is eventually connected in a clamping manner with the beverage can.

20. The method according to claim 19 , wherein the beverage can is transported with a covered filling opening from the filling station to a closing station and closed in the closing station permanently gas-tight.

21. The method according to claim 19 , wherein the lid is fixated at the beverage can directly after filling or directly after the filling station so that gas can move outward from the covered beverage can.

22. The method according to claim 20 , wherein the lid and the beverage can are connected permanently gas-tight with one another in the closing station through folding or border crimping.

23. The method according to claim 19 , wherein the lid for covering a beverage can is supplied to the beverage can under an inert gas atmosphere.

24. The method according to claim 19 , wherein the beverage can is filled with a beverage that includes carbonation.

25. The method according to claim 19 , wherein the beverage can is filled with a liquid food and an inert gas.

26. The method according to claim 25 , wherein the gas is filled into the beverage can in liquid or solid form.

27. The method according to claim 20 , wherein the beverage can is moved to the filling station on a circular path and moved on a tangent to the circular path to the closing station after being filled in the filling station.
