12. The device according to claim 9, wherein guidance of the pin (111) during movement improves the reproducibility of the cutting-off process of the tamper proofing seal (3) on the plate (12).

13. A system comprising the device according to claim 1 and the tamper proofing seal (3).

14. The system according to claim 13, wherein the tamper proofing seal (3) is a wire-shaped or a rod-shaped element.

15. The system according to claim 13, wherein the tamper proofing seal (3) is guided along the separating device, and bridges the lid (1) and the container (2).

16. A device for accurately cutting off a tamper proofing seal (3) securing a connection between a first part and a second part of a container, wherein the first part has a closure mechanism (11) to move within the first part or the second part between a secured state in which the first part is secured to the second part and an open state in which the first part can be released from the second part; a pin (111) attached to the closure mechanism (11); an aperture (112) extending through the pin (111); an associated aperture (141) extending through a reinforcement rib (14) in the first part or the second part; and a plate (12) is connected in a stationary manner to the reinforcement rib (14), the plate (12) having an edge (121) suitable for shearing off the tamper proofing seal (3), wherein the aperture (112) and the associated aperture (141) are aligned when the closure mechanism (11) is in the secured state and the tamper proofing seal (3) extends through the aperture (112) and the associated aperture (141), wherein the tamper proofing seal (3) is cut off at the edge (121) of the plate (12) when the closure mechanism (11) is moved relative to the first part or the second part.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1: Lid with a closure mechanism without a seal.

(2) FIG. 2: Lid with a closure mechanism with a wire seal.

(3) FIG. 3: Top view of lid with a closure mechanism.

DETAILED DESCRIPTION

(4) The invention is described in detail below with reference to the above figures in form and exemplary embodiment. In all figures, the same technical elements are marked with the same reference signs.

(5) FIG. 1 shows a section of a lid 1 or a part of a container with a closure mechanism 11. The closure mechanism 11 is suitable, for example, for connecting a lid 1 to a container or two parts of the container. This connection can only be released by moving the closure mechanism 11. The lid 1 or container part, as the case may be, has a number of reinforcing ribs 14 that stiffen the lid 1 or container, as the case may be, and form a receptacle for the closure mechanism 11. A pin 111 with a circular aperture 112 is attached to the closure mechanism 11. An opening of the closure mechanism 11 also simultaneously moves the pin 111 with respect to the separating device.

(6) The pin 111 itself is guided in movement by an aperture 142 in a reinforcing rib. A seal 13 designed as a wire can be guided through aperture 112 in a pin 111 and an associated aperture 141 in a reinforcing rib 14. An additional recess 143 in the reinforcing rib 14 fixes the wire-shaped seal 13 in place during a cutting off process.

(7) The cutting device is formed by three successive plates 12. The plates 12 are arranged here on the reinforcing rib 14 of the lid 1 or container, as the case may be, and are designed in one piece with the reinforcing rib 14. The first plate 12 is arranged in manner rotating relative to the reinforcing rib 14 in such a manner that one edge 121 of the first plate 12 is preferably used to cut off the seal 13. The other two plates 12 are attached at right angles to the reinforcing rib 14. Due to an elastic deformation of the second or third plate 12, as the case may be, in particular the twisting with respect to the direction of movement of the pin 111, during the movement of the pin 111 along the plates 12, the edge 121 facing the pin 111 becomes preferably usable as a separating edge.

(8) FIG. 2 shows the section of FIG. 1 with a wire-shaped seal 13 in the closed secured state of the closure mechanism 11. When the closure mechanism 11 is opened, the pin 111 is moved and also the part of the seal 13 guided through the opening 112 of the pin 111. Through the movement of the pin 111, the edge 121 of the first plate 12 slides along the surface of the pin 111, separating the wire-shaped seal 13.

(9) FIG. 3 shows a top view of a region of a lid 1 for a container 2 with a separating device consisting of three plates 12 and a pin 111. The plates 12 are attached to a reinforcing rib 14 of the lid 1, wherein the edge 121 for cutting off the seal 13 of the first plate 12 has a distance H from the reinforcing rib 14. The distance H is greater than the distance d, which is between the two facing aperture surfaces 121, 141 in the reinforcing rib 14 and the pin 111.
