Abstract

A closure for beverage containers that have a substantially cylindrical neck with an end opening and a closure cap includes a neck with an inside circumferential detent collar and a closure cap having an insertion shaft. A circumferential detent groove is provided on an outer circumference of the shaft. The detent groove corresponds to the detent collar, is profiled in a direction of insertion, and engages over the detent collar on a ring surface thereof that lies in the direction of insertion.

First claim

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

1. A closure for kegs having a substantially cylindrical neck with an end opening and a closure cap, wherein the neck has an inside circumferential detent collar and wherein the closure cap has an insertion shaft, an opening for receiving an extraction valve, and a circumferential detent groove provided on an outer circumference thereof, the detent groove corresponding to the detent collar and being profiled in a direction of insertion, wherein the detent groove engages over the detent collar on a ring surface thereof that lies in the direction of insertion, wherein the closure cap has a circumferential support and/or guide ring that engages over an outside of the neck, wherein the closure further comprising a structure selected from the group consisting of a seal, a circumferential retaining and/or guiding groove, and a circumferential support ring, wherein the seal is on a ring surface of the detent collar on an opening side thereof, wherein the circumferential retaining and/or guiding groove is on an outside of the neck, and wherein the circumferential support ring is on an inside of the neck.

2. The closure according to claim 1 , wherein the selected structure is the seal.

3. The closure according to claim 1 , further comprising a seal on the outer surface of the insertion shaft.

4. The closure according to claim 1 , wherein the selected structure is the circumferential retaining and/or guiding groove.

5. The closure according to claim 1 , wherein the selected structure is the circumferential support ring.

6. A closure for kegs having a substantially cylindrical neck with an end opening and a closure cap, wherein the neck has an inside circumferential detent collar and wherein the closure cap has an insertion shaft, an opening for receiving an extraction valve, and a circumferential detent groove provided on an outer circumference thereof, the detent groove corresponding to the detent collar and being profiled in a direction of insertion, wherein the detent groove engages over the detent collar on a ring surface thereof that lies in the direction of insertion, said closure further comprising a seal on a ring surface of the detent collar on an opening side thereof.

7. The closure according to claim 6 , further comprising a seal on the outer surface of the insertion shaft.

8. The closure according to claim 6 , further comprising a circumferential support ring on an outside of the neck.

9. The closure according to claim 6 , further comprising a circumferential retaining and/or guiding groove on an outside of the neck.

10. The closure according to claim 6 , further comprising a circumferential support ring on an inside of the neck.

11. A closure for kegs having a substantially cylindrical neck with an end opening and a closure cap, wherein the neck has an inside circumferential detent collar and wherein the closure cap has an insertion shaft, an opening for receiving an extraction valve, and a circumferential detent groove provided on an outer circumference thereof, the detent groove corresponding to the detent collar and being profiled in a direction of insertion, wherein the detent groove engages over the detent collar on a ring surface thereof that lies in the direction of insertion, said closure further comprising a circumferential retaining and/or guiding groove on an outside of the neck.

12. The closure according to claim 11 , further comprising a circumferential support ring on an inside of the neck.

13. The closure according to claim 12 , wherein the circumferential support ring is configured such that deformation of the closure cap jams the detent groove with the support ring.

14. The closure according to claim 11 , further comprising a circumferential support ring on an outside of the neck.

15. A closure for kegs having a substantially cylindrical neck with an end opening and a closure cap, wherein the neck has an inside circumferential detent collar and wherein the closure cap has an insertion shaft, an opening for receiving an extraction valve, and a circumferential detent groove provided on an outer circumference thereof, the detent groove corresponding to the detent collar and being profiled in a direction of insertion, wherein the detent groove engages over the detent collar on a ring surface thereof that lies in the direction of insertion, wherein said closure further comprises a seal on the outer surface of the insertion shaft and a circumferential retaining and/or guiding groove on an outside of the neck.

16. The closure according to claim 15 , further comprising a circumferential support ring on an outside of the neck.

17. A closure for kegs having a substantially cylindrical neck with an end opening and a closure cap, wherein the neck has an inside circumferential detent collar and wherein the closure cap has an insertion shaft, an opening for receiving an extraction valve, and a circumferential detent groove provided on an outer circumference thereof, the detent groove corresponding to the detent collar and being profiled in a direction of insertion, wherein the detent groove engages over the detent collar on a ring surface thereof that lies in the direction of insertion, further comprising a circumferential support ring on an outside of the neck, said closure further comprising a circumferential retaining and/or guiding groove on an outside of the neck.
