PROBLEM TO BE SOLVED: To make it possible to securely leave the trace of breakage when a board box is fraudulently opened.SOLUTION: In a first box, which is one of board boxes placed one on another, a sealing member 220 comprises a main plate 225 with a hole 226; a pocket part 228 that is open in one direction along the respective slide directions of both the boxes; and a bag part 229 that is open on the main plate side only. In the other second box, a sealing member 320 comprises: a block part 325; a hole 327 extending from the block part 325 in other direction along the sliding direction; and a locking piece 326 inserted into the pocket part. A sealing pin 400 having a locking claw and inserted from the hole 226 is passed through the hole 327 of the locking piece, so that the locking claw locks to the locking piece, thus inhibiting the separation thereof. The flat face 325a of a block part is in face-contact with a flat face 229a in which a pocket part is open, thus the locking portion of the locking claw and locking piece is blocked from outside. To unlock the locking portion of the sealing pin, the pocket part has to be broken. Accordingly, the trace of breakage is left. |
