Abstract

Claims (12)

1. A method for producing at least one aroma protection valve ( 10 a ) for a packaging container, having a basic element ( 12 a ) and having a valve membrane ( 14 a ) which is connected at least in sections to the basic element ( 12 a ) in a joining process ( 100 a ) by an energy input, the basic element ( 12 a ) and the valve membrane ( 14 a ) being connected to each other without an adhesive in the joining process ( 100 a ), wherein the basic element ( 12 a ) and the valve membrane ( 14 a ) are connected at least in sections in the joining process ( 100 a ) by ultrasonic welding ( 26 a ), wherein the basic element ( 12 a ) and the valve membrane ( 14 a ) are connected to each other in the joining process ( 100 a ) on a base element ( 50 a ) which is provided for handling and/or stabilizing the basic element ( 12 a ) and/or the valve membrane ( 14 a ) during the joining process ( 100 a ).

2. The method as claimed in claim 1 , wherein the basic element ( 12 a ) and the valve membrane ( 14 a ) are connected to each other in a continuous joining process ( 100 a ).

3. The method as claimed in claim 1 , wherein the basic element ( 12 a ) and the valve membrane ( 14 a ) are connected to each other along at least one joining seam ( 16 a ) in the joining process ( 100 a ).

4. The method as claimed in claim 1 , wherein the basic element ( 12 a ) has at least one opening ( 20 a ), and, in the joining process ( 100 a ), the basic element ( 12 a ) and the valve membrane ( 14 a ) are connected to each other along at least two joining seams ( 16 a , 18 a ) on opposite sides of the opening ( 20 a ).

5. The method as claimed in claim 1 , wherein the basic element ( 12 a ) and/or the valve membrane ( 14 a ) are/is heated in the joining process ( 100 a ).

6. The method as claimed in claim 1 , wherein the basic element ( 12 a ) and the valve membrane ( 14 a ) are connected at least in sections in the joining process ( 100 a ) by ultrasonic roll seam welding ( 28 a ).

7. The method as claimed in claim 1 , wherein a thermoplastic is at least partially used as the basic element ( 12 a ).

8. The method as claimed in claim 1 , wherein the basic element ( 12 a ) and the valve membrane ( 14 a ) have at least substantially same expansion properties.

9. The method as claimed in claim 1 , wherein the basic element ( 12 a ) and the valve membrane ( 14 a ) are at least partially formed from a same material.

10. The method as claimed in claim 1 , wherein the basic element ( 12 a ) and the valve membrane ( 14 a ) after being joined are guided at least substantially horizontally away from a joining region ( 32 a ).

11. The method as claimed in claim 1 , wherein the aroma protection valve ( 10 a ) comprises at least one functional element ( 36 a ) which is connected to the valve membrane ( 14 a ), in a further joining process ( 102 a ), on a side ( 38 a ) of the valve membrane ( 14 a ) that faces away from the basic element ( 12 a ).

12. An aroma protection valve ( 10 a ) for a packaging container, which is at least partially produced by a method as claimed in claim 1 , wherein the basic element ( 12 a ) and the valve membrane ( 14 a ) were connected to each other in a joining process ( 100 a ) on a base element ( 50 a ), that is removable for an application process in which the aroma protection valve can be arranged on the packaging container.
