PROBLEM TO BE SOLVED: To improve burglarproof effects of an article in a case with a burglarproof function for receiving a rental article or the like by providing juxtaposed engaging grooves on upper rims of both sidewalls of the case and by detachably inserting an engaging board into the grooves in an engaged state to prevent both walls from separating. SOLUTION: Juxtaposed engaging grooves 18, 18 are provided on upper rims of both sidewalls 11, 15 on a lid of a case A, while an engaging board 19 is inserted into groove portions formed by the grooves 18, 18 in an engaged state to prevent both sidewalls 11, 15 from separating and in a state that the board can be removed. At the time of use, an article (a) such as a CD is put in a box 17, and after the box 17 is closed by a lid 13, the engaging board 19 is inserted between the juxtaposed engaging grooves 18, 18. Thus the lid 13 is prevented from opening from the box 17, whereby even if the article (a) is taken out of the case A where it is displayed, it is necessary to remove the engaging board 19. Therefore, theft can be prevented as there is another trouble of removing the engaging board and there may be hesitation in removing. |
