<p>PROBLEM TO BE SOLVED: To provide a sealing device which prohibits resealing once the sealed loop is disengaged and such a sealing device which, when sealing is deliberately ruptured, allows this state to remain. SOLUTION: The sealing device 30 consists of a filament part 3, an insertion head part 19 which is disposed at one end of this filament 3 and has an engaging part 23 consisting of a hook part, etc., and a socket part 2 which is disposed at the other end of the filament part 3 and has a hole 10 for irreversible passage of this insertion head part 19. In such a case, the sealing device is so constituted that the tensile strength of the insertion head part 19 is lower than the tensile strength of the filament part 3.</p> |
