PROBLEM TO BE SOLVED: To surely leave the trace of destruction when a board box is unlawfully opened. SOLUTION: In one first box forming the board box by being piled up, a sealing member 220 includes a main plate 225 provided with a hole 226, a pocket part 228 opened in one direction along the sliding direction of both boxes, and a bag part 229 opened only on the main plate side. In the other second box, a sealing member 320 includes a block part 325, and a locking piece 326 extended from it in the other direction along the sliding direction, provided with a hole 327 and inserted into the pocket part. A sealing pin 400 provided with a locking pawl and inserted from the hole 226 passes through the hole 327 of the locking piece, the locking pawl is locked to the locking piece and detachment is inhibited. The flat surface 325a of the block part and the flat surface 229a where the pocket part is opened are brought into surface contact and the locking part of the locking pawl and the locking piece is shut off from the outside. Since the pocket part has to be destroyed in order to open the locking part of the sealing pin, the trace is left. COPYRIGHT: (C)2011,JPO&INPIT |
