Abstract

A security seal for a medical container includes a seal foot having at least one latch structure movable relative thereto for engaging a mating latch structure formed on the container, and a seal head connected with the seal foot that includes at least one locking tab which is movably connected with the seal head through a hinge element, wherein the security seal includes a bolt element which can be positioned between a release position, in which the latch structure can be moved relative to the seal foot, and a locked position, in which the deformable latch structure is fixed in position relative to the seal foot and/or seal head.

First claim

The invention claimed is:

1. A security seal for a medical container, the security seal comprising:
a seal foot having a substantially circular cross-section and having at least one latch structure movable relative to the seal foot for engaging a mating latch structure formed on the medical container, and
a seal head connected with the seal foot and comprising at least one locking tab which is movably connected with the seal head through a hinge element,
the security seal comprising a bolt element which can be positioned between a release position, in which the at least one latch structure can be moved relative to the seal foot, and a locked position, in which the at least one latch structure is fixed in position relative to the seal foot,
wherein
the seal foot comprises at least two spring arms extending from the seal head, each of said at least two spring arms having a distal end provided with a latching protrusion, the latching protrusions protruding radially outwardly, wherein the at least two spring arms are each formed as a partial cylinder and arranged around a through-hole which is formed in the seal head and fully penetrates the seal head, the through-hole serving to receive and guide the bolt element.

2. The security seal according to claim 1 , wherein the bolt element has a bolt-like design and is arranged so as to be able to be positioned in the direction of its longitudinal axis relative to at least one of the seal head and the seal foot.

3. The security seal according to claim 1 , wherein the bolt element is supported on or in a through-hole formed in at least one of the seal head and seal foot.

4. The security seal according to claim 1 , wherein the bolt element in its locked position fixes the at least one latch structure.

5. The security seal according to claim 1 , wherein the bolt element is connected with at least one of the seal head and the seal foot in the release position via predetermined breaking points and is held in its axial position, said predetermined breaking points being destroyed when transferring the bolt element from the release position to the locked position.

6. The security seal according to claim 1 , wherein at least one contact shoulder extending in a radial direction is formed on the bolt element, said at least one contact shoulder engaging a mating contact shoulder formed on at least one of the seal foot and the seal head during transfer of the bolt element to the locked position, so that any movement of the bolt element from the locked position back to the release position is prevented.

7. The security seal according to claim 1 , wherein the at least one latch structure comprises the latching protrusions.

8. The security seal according to claim 1 , wherein the at least one latch structure comprises a plurality of radially opposite latch structures which are positioned at equal angular distances.

9. A system comprising a medical container and a security seal according to claim 1 .

10. The system according to claim 9 , wherein when the at least one latch structure is in a non-deformed state and arranged on the container as intended, the security seal engages the mating latch structure in an undetachable manner and can be elastically deformed from the non-deformed state for arranging it as intended.

11. The security seal according to claim 1 , wherein an end of the bolt element facing the seal foot has a star-shaped end structure comprising a plurality of tips, the tips of the star-shaped end structure resting against inner surfaces of the at least two spring arms and preventing radially inward deformation of the at least two spring arms in the locked position.

12. The security seal according to claim 1 ,
wherein
the bolt element comprises a bolt head and a bolt shaft, the bolt shaft beinq provided with a pocket incorporated in a radial direction in the bolt shaft, circumferentially surrounding the bolt shaft in part and discontinued by two axial grooves, and
wherein each of the spring arms has its radially inner side provided with a latching protrusion which serves for engaging the pocket.

13. The security seal according to claim 1 ,
wherein
the bolt element comprises a bolt head and a bolt shaft, the bolt shaft being provided with a pocket incorporated in a radial direction in the bolt shaft, circumferentially surrounding the bolt shaft in part and discontinued by two axial grooves, and
wherein the through-hole has two areas which protrude radially inwards and engage the axial grooves and guide the bolt element when the bolt element is inserted in the through-hole.

14. The security seal according to claim 1 , wherein the bolt element comprises a bolt head and a bolt shaft, the bolt shaft being provided with a pocket incorporated in a radial direction in the bolt shaft, circumferentially surrounding the bolt shaft in part and discontinued by at least one axial groove.

15. A security seal for a medical container, the security seal comprising:
a seal foot having a substantially circular cross-section and having at least one latch structure movable relative to the seal foot for engaging a mating latch structure formed on the medical container, and
a seal head connected with the seal foot and comprising at least one locking tab which is movably connected with the seal head through a hinge element,
the security seal comprising a bolt element which can be positioned between a release position, in which the at least one latch structure can be moved relative to the seal foot, and a locked position, in which the at least one latch structure is fixed in position relative to the seal foot, wherein
the bolt element comprises a bolt head and a bolt shaft, the bolt shaft being provided with a pocket incorporated in a radial direction in the bolt shaft, circumferentially surrounding the bolt shaft in part and discontinued by at least one axial groove.
