Abstract

The present invention discloses a security seal with a seal base with at least one locking projection and a seal head connected to the seal base with at least one blocking tab, whereby each blocking tab is movably connected to the seal head via at least one hinge element, together with 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 on which the seal base of a security seal can be engaged 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 the side of the second closure part opposite the first closure part, and additionally, a security container with a container tub, a lid and a safety closure, wherein either the first or second closure part is arranged on either the container tub or the lid, respectively.

First claim

The invention claimed is:

1. 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 each 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 the same angular distance from one another and wherein an even number of locking projections are provided, and wherein the blocking tab has a rectangular cross-section and wherein the locking projections extend towards the seal base as the at least one blocking tab extends towards the seal head.

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

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

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

5. Security seal in accordance with clam 1 , wherein each blocking tab is provided with two hinge elements, on the side of the seal head.

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

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

8. Security seal in accordance with claim 1 , wherein one of the at least one locking projection projects outwards from the seal base in a radial direction.

9. 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. Security seal in accordance with claim 1 , wherein at least one locking projection on the seal base is elastically mounted and projects radially inwards.

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

12. Security seal in accordance with claim 1 , wherein at least one elastic spring tab is arranged on the seal head, which projects radially over the inner edge of a blocking tab.

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

14. 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.

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

16. 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.

17. Safety closure in accordance with claim 16 , 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.

18. Safety closure in accordance with claim 16 , 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, in particular, cannot be turned, tilted and/or shifted, while the security seal can be moved towards the first closure part when the second closure part is in the open position, in particular, turned, tilted and shifted.

19. Safety closure in accordance with claim 16 , 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.

20. Safety closure in accordance with claim 16 , 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.

21. Safety closure in accordance with claim 16 , 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.

22. Safety closure in accordance with claim 16 , 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.

23. Security container according to claim 16 , including a container tub, a lid and a safety closure, wherein either the first or the second closure part is arranged on either the container tub or the lid respectively.

24. Security container in accordance with claim 23 , wherein at least the first closure part or 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.

25. Sterilization container with a container tub with at least a first closure part, which has a recess with two opposing curved contact surfaces formed on two curved sections, so that the recess is aligned to receive a seal base of a security seal, the recess has an essentially circular cross-section and two locking projections projecting radially outwards and which can be inserted into the recess in an axial direction so that the locking projections create a locking undercut with the curved sections and a lateral surface of the seal base is partially seated on a contact surface and is also aligned so that a snap-on connection between the locking projections and the curved sections can be lifted off by turning the security seal around its longitudinal axis through roughly 90° , so that the security seal can be removed from the recess, and
a container lid, which has at least one locking tab, which is swivel-mounted to the container lid so that it can be moved back and forth from an open position to a closed position, and a second closure part, which has a through-hole, which has an essentially non-rotationally symmetrical cross-section and is aligned to interlock with a seal head of the security seal in the direction of rotation so that moving the locking tab in the direction of the open position relative to the security seal results in at least one blocking tab arranged on the seal head of the security seal being positioned on at least one part of an edge of the through-hole and continued movement of the blocking tab in one direction results in at least partial plastic deformation of the at least one blocking tab so that th
