The present invention proposes a sealing bolt (10) for sealing a container lid (12) to a container body (14) with a threaded bore (28), the sealing bolt (10) comprising a bolt shaft (18) having a first shaft end (20) and a threaded second shaft end (22) opposite to the first shaft end (20), and a bolt head (16) connected to the first shaft end (20), the threaded second shaft end (22) cooperating with the threaded bore (28) so as to allow the sealing bolt (10) to lock the container lid (12) between the bolt head (16) and the container body (14), the sealing bolt (10) further comprising a security element with a breakable integrity element (34) for verifying the integrity of the sealing bolt (10). According to an important aspect of the invention, the security element comprises a first part (30) arranged at the second shaft end (22) of the bolt shaft (18), the first part (30) being connected to the bolt shaft (18) and comprising the breakable integrity element (34) therebetween, the first part (30) having a first thread (36) cooperating with the threaded bore (28); a second part (32) arranged between the first part (30) and the second shaft end (22) of the bolt shaft (18), the second part (32) having a second thread (38) cooperating with the threaded bore (28); and a first entrainment means (50) arranged between the first and second parts (30, 32). The first entrainment means (50) is arranged in such a way that, upon rotation of the bolt shaft (18) and the first part (30) in a first direction (52), the second part (32) is entrained in the first direction (52), and, upon rotation of the bolt shaft (18) and the first part (30) in a second direction (54), opposite to the first direction (52), the second part (32) remains stationary.
Sealing bolt for sealing a container lid to a container body with a threaded bore, said sealing bolt comprising a bolt shaft having a first shaft end and a threaded second shaft end opposite to said first shaft end, and a bolt head connected to said first shaft end, said threaded second shaft end cooperating with said threaded bore so as to allow said sealing bolt to lock said container lid between said bolt head and said container body, said sealing bolt further comprising a security element with a breakable integrity element for verifying the integrity of said sealing bolt,
Sealing bolt according to claim 8, wherein said ultrasonic identity element comprises a stack of disks with randomly arranged notches.
