Abstract

A security seal includes a base with a locking projection and a head connected to the base with at least one blocking tab. Each blocking tab is connected to the head via a hinge element, together with a safety closure with a first closure part and a second closure part, which can be moved between an open position and a closed position relative to the first closure part. The first closure part has a seating on which the base of a security seal can be engaged so that, when the second closure part is in the closed position, a blocking tab of the security seal overlaps the second closure part on the side opposite the first closure part. A security container includes a container tub, lid and safety closure, wherein either the first or second closure part is arranged on either the container tub or lid.

First claim

The invention claimed is:

1. A security seal with a seal base with at least two locking projections, and a seal head connected to the seal base with at least one blocking tab, wherein the at least two locking projections are elastically movable in a radial direction, and the at least one blocking tab is movably connected to the seal base by at least one hinge element, and wherein the at least two locking projections are arranged around the seal base at an equal angular distance from one another, and wherein an even number of locking projections are provided, and wherein the at least one blocking tab has a rectangular cross-section, and wherein at least one elastic spring tab is arranged on the seal head, which projects radially over an inner edge of the at least one blocking tab.

2. The security seal in accordance with claim 1 , wherein the at least one hinge element can be at least partially plastically deformed.

3. The security seal in accordance with claim 1 , which is designed as one piece, made from plastic.

4. The security seal in accordance with claim 1 , with two opposing, in a radial direction, blocking tabs.

5. The security seal in accordance with clam 1 , wherein the at least one blocking tab is provided with two hinge elements, on a side of the seal head.

6. The security seal in accordance with claim 1 , wherein the seal base has an essentially circular cross-section.

7. The security seal in accordance with claim 1 , wherein the at least one blocking tab projects radially at least partially towards the seal base.

8. The security seal in accordance with claim 1 , wherein one of the at least two locking projections projects outwards from the seal base in a radial direction.

9. The security seal in accordance with claim 1 , wherein at least one radial projection or recess is formed on the seal head or on the seal base, with which a side of the at least one blocking tab facing the seal base is in contact.

10. The security seal in accordance with claim 1 , wherein at least one of the at least two locking projections on the seal base is elastically mounted and projects radially inwards.

11. The security seal in accordance with claim 1 , wherein one of two, four or six locking projections are provided.

12. The security seal in accordance with claim 1 , wherein the at least one elastic spring tab is mounted on the upper surface of the seal head, centrally.

13. The security seal in accordance with claim 1 , wherein at least one radially projecting locking projection is arranged on the lateral surface of the seal head and a lug is arranged on at least one blocking tab so that the lug is located opposite the at least one radially projecting locking projection and is arranged further towards the seal base in an axial direction in comparison with the at least one radially projecting locking projection.

14. The security seal in accordance with claim 13 , wherein at least the lug or the at least one radially projecting locking projection is formed so as to be elastically flexible.

15. A safety closure with a first closure part and a second closure part, which can be moved back and forth between an open position and a closed position relative to the first closure part, wherein the first closure part has a seating, the seating configured to receive a seal base of a security seal in accordance with claim 1 so that, when the second closure part is in the closed position, at least one blocking tab of the security seal at least partially overlaps the second closure part on side of the second closure part opposed to the first closure part.

16. The safety closure in accordance with claim 15 , wherein the second closure part has a recess and a through-hole through which the seal base can be inserted and can be engaged in the seal seating of the first closure part when the second closure part is in the closed position.

17. The safety closure in accordance with claim 15 , wherein the seal base of the security seal can be engaged in the seal seating of the first closure part when the second closure part is in the closed position so that the security seal is interlocked with the second closure part so that the security seal opposite the first closure part is essentially held immovably while the security seal can be moved towards the first closure part when the second closure part is in the open position.

18. The safety closure in accordance with claim 17 , wherein a seating on the first closure part has at least one recess, with an essentially rotationally symmetrical section, with at least one radial outward widening, into which the seal base of a security seal can be inserted.

19. The safety closure in accordance with claim 17 , wherein the seating on the first closure part is an essentially circular recess with at least one radial outward and inward widening, into which the least one locking projection can be inserted.

20. The safety closure in accordance with claim 17 , wherein a seating on the first closure part is a mushroom-shaped projection, on which the seal base of a security seal can be placed.

21. The safety closure in accordance with claim 17 , which has at least one of a snap-in mechanism, with which the second closure part can be locked on to the first closure part.

22. A security container comprising a container tub, a lid and a safety closure according to claim 15 , wherein either the first or the second closure part is arranged on either the container tub or the lid respectively.

23. The security container in accordance with claim 22 , wherein at least one of the first closure part and the second closure part is arranged on a locking tab, which is correspondingly arranged on the container tub and the lid so as to be able to pivot.

24. A security seal comprising:
a seal base having at least one locking projection;
a seal head connected to the seal base, the seal head comprising at least one blocking tab; and
at least one elastic spring tab arranged on the seal head and projecting over an inner edge of the at least one blocking tab,
the at least one locking projection being elastically movable, and
the at least one blocking tab being movably connected to the seal base by at least one hinge element.
