Abstract

A tamper evident closure for an access opening in a container has a closure part which is placeable onto the access opening in a sealing manner and has a bottom sleeve portion and an upper cover portion which are connected in one piece to each other via a first tamper evident indicator. A hood-like indicator cap forms a second tamper evident indicator and at least partially surrounds at least the cover portion of the closure part, wherein access to the first indicator is possible only when the indicator cap is destroyed. A tear off tab is formed in the indicator cap, which is bounded by two grooves which are arranged at a distance and end at a distance from the bottom rim of the indicator cap, wherein at least one of the grooves is assigned a breaking point which extends as far as the bottom rim of the indicator cap.

Claims

1. Tamper evident closure for an access opening in a container, with a closure part which is placeable onto the access opening in a sealing manner and has a bottom sleeve portion and a cover portion, which are connected in one piece to each other via a first tamper evident indicator, and with a hood-like indicator cap which forms a second tamper evident indicator and at least partially surrounds at least the cover portion of the closure part, wherein access to the first tamper evident seal is possible only when the indicator cap is destroyed, and wherein a tear off tab is formed in the indictor cap, the tear off tab is bounded by two grooves which are arranged at a distance and end at a distance from bottom rim of the indicator cap, and in that at least one of the grooves is assigned a breaking point which extends as far as the bottom rim of the indicator cap.

2. Tamper evident closure according to claim 1, wherein the breaking point assigned to at least one of the grooves, is formed by a cross-sectional weakening and/or a perforation.

3. Tamper evident closure according to claim 1, wherein each of grooves is assigned a breaking point each of which extends as far as the bottom rim of the indicator cap.

4. Tamper evident closure according to claim 3, wherein the breaking points are formed by a cross-sectional weakening and/or a perforation.

5. Tamper evident closure according to claim 1, wherein the grooves run vertically.

6. Tamper evident closure according to claim 1, wherein both the grooves of the indicator cap are of equal length.

7. Tamper evident closure according to claim 1, wherein the tear off tab is offset radially inwards relative to outer skin surface of the indicator cap.

8. Tamper evident closure according to claim 1, wherein the tear off tab is connected at its upper end facing away from the breaking point to a handle tab.

9. Tamper evident closure according to claim 8, wherein the handle tab is integrated in the indicator cap and is fixed therein via breaking regions which can be broken off.

10. Tamper evident closure according to claim 9, wherein the handle tab is provided with hinges disposed on the handle tab along a hinge axis A-A, dividing the handle tab into a first handle tab portion and a second handle tab portion.

11. Tamper evident closure according to claim 10, wherein the first handle tab portion of the handle tab is connected with the indicator cap via at least two breaking regions and the second handle tab potion is connected to the indicator cap via breaking regions.

12. Tamper evident closure according to claim 8, wherein an actuating part for releasing the handle tab is formed on the handle tab on the side facing away from the grooves.

13. Tamper evident closure according to claim 1, wherein the cover portion of the closure part is screw cap.

14. Tamper evident closure according to claim 1, wherein the first tamper evident indicator is formed by webs via which the sleeve portion and the cover portion are connected to each other and which can inevitably break off when the cover portion is opened for the first time.

15. Tamper evident closure according to claim 1, wherein the first tamper evident indicator is formed by a circumferential band which is bounded by two perforation lines and runs between the sleeve portions and the cover portion of the closure part.

16. Tamper evident closure according to claim 1, wherein the indicator cap is placed from above onto the cover portion and the first tamper evident indicator.

17. Tamper evident closure according to claim 16, wherein a circumferential rib is provided at interior of the indicator cap which is engageable with a corresponding circumferential provided on upper part of the sleeve portion to latching or engaging the indicator cap with the closure part.

18. Tamper evident closure according to claim 17, wherein the engagement or latching between the indicator and closure part is further secured by provide welding or gluing at the location of engagement or latch.

19. A hood-like indicator cap for a tamper evident closure, comprising a sleeve-shaped basic body, a tear off tab is formed in the basic body, the tear off tab is bounded by two grooves which are arranged at a distance and end at a distance from bottom rim of the indicator cap, and in that at least one of the grooves is assigned a breaking point which extends as far as the bottom rim of the indicator cap.

20. A hood-like indicator cap according to claim 19, wherein the breaking point assigned to at least one of the grooves, is formed by a cross-sectional weakening and/or a perforation.

21. A hood-like indicator cap according to claim 19, wherein each of grooves is assigned a breaking point each of which extends as far as the bottom rim of the indicator cap.

22. A hood-like indicator cap according to claim 21, wherein the breaking points are formed by a cross-sectional weakening and/or a perforation.

23. A hood-like indicator cap for a tamper evident closure according to claim 19 wherein the tear off tab is offset radially inwards relative to outer skin surface of the basic body.

24. A hood-like indicator cap for a tamper evident closure according to claim 19 wherein the tear off tab is connected at its upper end facing away from the breaking point to a tab.

25. A hood-like indicator cap for a tamper evident closure according to claim 24 wherein the handle tab is connected to the basic body via breaking regions which can be broken off.

26. A hood-like indicator cap for a tamper evident closure according to claim 25 wherein the handle tab is provided with hinges disposed on the handle tab along hinge axis A-A, thereby dividing the handle tab into a first handle tab portion and a second handle tab portion.

27. A hood-like indicator cap for a tamper evident closure according to claim 26 wherein the first handle tab portion of the handle tab is connected with the basic body via at least two breaking regions and the second handle tab portion is connected to the indicator cap via breaking regions.

28. A hood-like indicator cap for a tamper evident closure according to claim 24, wherein an actuating part for releasing the handle tab is formed on the handle tab on the side facing away from the grooves.
