Abstract
The present disclosure relates to a sealing device (10) for a container. The sealing device comprises a housing (12) housing an integrated circuit (14). A locking member (16) is slidably attached to the housing (12) and includes an electrical conductor (19) embedded therein. The electrical conductor (19) and the integrated circuit (14) form an RFID circuit when the locking member (16) is in a locking position. The electrical connection between the electrical conductor (19) and the integrated circuit (14) is broken when the locking member (16) is cut or forcibly removed from the housing (12) and cannot be re-established. In this manner, a manipulation of the sealing device (10) can be reliably prevented.
Claims18
A sealing device comprising:
- a housing accommodating an integrated circuit;
- a locking member slidably attached to the housing, the locking member having a first end slidably accommodated in the housing in a manner that it cannot be removed from the same, an electrical conductor embedded in the locking member and electrically connected to the integrated circuit, and a second end configured to be inserted into the housing when the locking member is slid along a locking direction from an unlocking position, in which the second end is disposed outside the housing, to a locking position, in which the second end is disposed in the housing;
- a locking mechanism configured to securely engage the locking member in the locking position;
- and
- a contact device provided in the housing and electrically connected to the integrated circuit;
- wherein an electrical conductor includes:
- a wire extending inside the locking member substantially between the first end and the second end;
- and
- an electrically conducting contact pin embedded in the locking member at the second end, the contact pin being electrically connected to the wire and at least partially exposed from the locking member to come into contact with the contact device when the second end is engaged by the locking mechanism;
- and
- wherein an electrical connection between the electrical conductor and the contact device is established after engagement of the second end by the locking mechanism.
A sealing device comprising:

- a locking member slidably attached to the housing, the locking member having a first end slidably accommodated in the housing in a manner that it cannot be removed from the same, an electrical conductor embedded in the locking member and electrically connected to the integrated circuit, and a second end configured to be inserted into the housing when the locking member is slid along a locking direction from an unlocking position, in which the second end is disposed outside the housing, to a locking position, in which the second end is disposed in the housing;
- a locking mechanism configured to securely engage the locking member in the locking position;
- and
- a contact device provided in the housing and electrically connected to the integrated circuit;
- wherein an electrical connection between the electrical conductor and the contact device is established after engagement of the second end by the locking mechanism;
- and
- wherein the integrated circuit and the electrical conductor form at least part of an RFID circuit.
