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.
