Abstract

A device for closing a filled container with a screw cap, for example, for closing support ring-less bottles with a screw cap, is described. The device includes a neck guide with at least one torsion protection element for accommodation of a neck section of the filled container in a torsion-protected manner during the closing with the screw cap, and a discharge element for discharging the closed container from the neck guide. The neck guide and the discharge element are displaceable relative to each other.

First claim

The invention claimed is:

1. A device for closing a filled container with a screw cap, comprising:
a neck guide with at least one torsion protection element configured to accommodate a neck section of the filled container during the closing with the screw cap; and
a discharge element configured to discharge a closed container from the neck guide,

wherein:
the neck guide and the discharge element are displaceable relative to each other,
the discharge element comprises at least one lifting finger which is disposed below the at least one torsion protection element in a capping position and is disposed at least at substantially the same level as the at least one torsion protection element in a discharge position,
the at least one lifting finger is configured to lift the closed container out of the at least one torsion protection element and is disposed in a complementary recess of the neck guide in the capping position, and
the filled container comprises a bottle having no support ring.

2. The device of claim 1 , wherein the neck guide and the discharge element are disposed on a rotary carousel.

3. The device of claim 1 , further comprising a guide bolt configured to guide the discharge element in a vertical direction.

4. The device of claim 1 , further comprising a second neck guide.

5. The device of claim 4 , wherein each neck guide is displaceable along a predetermined movement path and is associated with its own discharge element.

6. The device of claim 1 , wherein the at least one lifting finger comprises four lifting fingers.

7. The device of claim 1 , wherein the at least one lifting finger forms a substantially continuous surface with the neck guide.

8. The device of claim 1 , wherein the discharge element and the neck guide are displaceable relative to each other in a vertical direction.

9. The device of claim 1 , wherein the neck guide is configured so that only the at least one torsion protection element is in contact with the filled container in the capping position.

10. The device of claim 9 , wherein the neck guide comprises a collar that is configured to surround at least part of a neck section of the filled container.

11. The device of claim 10 , wherein the at least one torsion protection element is disposed on an upper end surface of the collar and is configured to accommodate a security ring of the filled container.

12. The device of claim 1 , wherein the discharge element and the neck guide are displaceable relative to each other without touching each other.

13. The device of claim 1 , wherein the discharge element comprises a magnet.

14. The device of claim 1 , wherein the discharge element is pre-tensioned relative to the neck guide in the capping position.

15. A method for closing a container by using the device of claim 1 , comprising:
placing the container on the at least one torsion protection element;
closing the container with the screw cap;
engaging the discharge element with the closed container; and
displacing the discharge element relative to the neck guide to lift the closed container from the at least one torsion protection element.

16. The method of claim 15 , wherein the at least one torsion protection element penetrates into an area formed by a warranty band of the screw cap and comes into contact with a security ring of the container.

17. The device of claim 1 , wherein the at least one lifting finger is configured to come into contact with the filled container only when the filled container is closed.

18. A device for closing a filled container with a screw cap, comprising:
a neck guide with at least one torsion protection element configured to accommodate a neck section of the filled container during the closing with the screw cap; and
a discharge element configured to discharge a closed container from the neck guide,

wherein:
the neck guide and the discharge element are displaceable relative to each other,
the discharge element comprises a plurality of lifting fingers which are disposed below the at least one torsion protection element in a capping position and are disposed at least at substantially the same level as the at least one torsion protection element in a discharge position, and
the plurality of lifting fingers are configured to lift the closed container out of the at least one torsion protection element, and are disposed in complementary recesses of the neck guide in the capping position.

19. The device of claim 18 , wherein the plurality of lifting fingers are configured to engage the closed container in differing positions around a circumference of the closed container during lifting.

20. The device of claim 18 , wherein the plurality of fingers form a substantially flat and continuous surface in the capping position.
