CLOSURE WITH PASSIVE ELECTRONIC SENSOR FOR TAMPER DETECTION AND RELATED METHOD
First Claim
1. A closure comprising:
- a closing member for sealing an opening of a pressurized container; and
a passive electronic sensor coupled to the closing member, the sensor including;
a status register responsive to a pressure change in the pressurized container caused by at least one of an insertion of the closing member into the opening or an extraction of the closing member from the opening.

Abstract
A closure includes a closing member for sealing an opening of a pressurized container. The closing member may include a passive electronic sensor coupled thereto that includes a status register that may be readable by, for example, a RFID reader. The status register is responsive to a pressure change in the pressurized container caused by an insertion of the closing member into the opening or an extraction of the closing member from the opening. The status value in the status register indicates whether the pressurized container has been tampered with. An identification register may include a pressurized container identification encrypted with the private key of the manufacturer, which can be decrypted for comparing to identification on the pressurized container to identify tampering.

10. A method comprising:
-
providing a closing member for sealing an opening of a pressurized container, the closing member including a passive electronic sensor coupled to the closing member, the passive electronic sensor including a status register; registering in the status register a pressure change in the pressurized container caused by at least one of an insertion of the closing member into the opening or an extraction of the closing member from the opening; and reading the status register of the passive electronic sensor to determine whether the closing member has been tampered with. - View Dependent Claims (11, 12, 13, 14, 15)

16. A closure comprising:
-
a closing member for sealing an opening of a pressurized container; and a radio frequency identification (RFID) processor readable by a RFID reader, the RFID tag positioned within the closing member, the RFID processor including; a status register responsive to a pressure change in the pressurized container caused by at least one of a non-initial insertion of the closing member into the opening or an extraction of the closing member from the opening, and an identification register for storing a pressurized container identification that is to be identical to an identification assigned to the pressurized container. - View Dependent Claims (17, 18, 19, 20)
