PROBLEM TO BE SOLVED: To prevent fabrication of a new board box without a trace of destruction when a board box is opened. SOLUTION: A sealing member on a first box side is composed of a main plate 225, a pocket 228 and a bag 229. A sealing member on a second box side is composed of a locking piece 326 extended from a block part 325 to be inserted into the pocket 228. A locking pawl 408 of a sealing pin 400 inserted into the bag from a hole 226 of the main plate through a hole 327 of the locking piece is locked with the locking piece. A head having a weak projection piece 404 of the sealing pin is coated with cured resin P. When the cured resin is forced to be scraped off to withdraw the projection piece 404 by force, the projection piece is torn off together with the cured resin, and the trace remains. As a new sealing pin can not be obtained, a new board box can not be fabricated even if the first and second boxes without trace of destruction can be obtained. COPYRIGHT: (C)2010,JPO&INPIT |
