Abstract: A sealing device including a housing and a closure member having a first end and a second end, at least one of the first and second ends being removably attached to the housing, the housing having means for checking the integrity of the closure member and a first transponder for transmitting information on the status of the sealing device where, the sealing device further includes a second transponder, preferably a passive transponder, associated with at least one of the first and second ends (16, 20) of the closure member, the second transponder comprising a second identity, and a transponder reader associated with the first transponder, preferably an active transponder, the transponder reader being arranged for reading the second identity of the second transponder; the first transponder being configured for receiving the second identity from the transponder reader and for transmitting the second identity.

Abstract: A sealing bolt for sealing a container lid to a container body, the sealing bolt including: a first identity element configured so as to provide a first identification signal when sensed with an ultrasonic reading device; a second identity element configured so as to provide a second identification signal when sensed with an ultrasonic reading device; and a third identity element. The third identity element includes the first and second identity elements and a third identification signal is formed by the intersection points created by an overlap of the first and second identification signals. The invention also concerns a method for sealing a container lid to a container body using such a sealing bolt.
