SEALING BOLT

摘要

A sealing bolt (10) for sealing a container lid (12) to a container body (14), the sealing bolt (10) comprising: a first identity element (32) configured so as to provide a first identification signal (c1) when sensed with an ultrasonic reading device; a second identity element (34) configured so as to provide a second identification signal (c2) when sensed with an ultrasonic reading device; and a third identity element. The third identity element comprises the first and second identity elements (32, 34) and a third identification signal is formed by the intersection points (P) created by an overlap of the first and second identification signals (c1, c2). The invention also concerns a method for sealing a container lid (12) to a container body (14) using such a sealing bolt (10).
