PROBLEM TO BE SOLVED: To prevent a fold of an inside bag from being extruded to the outside of a box when a bag-in-box is packaged. SOLUTION: This box sealing apparatus comprises a transfer unit for transfering a bag-in-box 2, a flap folding unit for folding flaps 4 (4A, 4B) of the bag-in-box 2, and box sealing unit for sticking a tape to a joint of the flaps 4 (4A, 4B), thereby sealing the bag-in-box 2. In this case, a nozzle 30 is provided which blows a high-speed air stream to a fold 27 positioned on the upstream side of an inside bag 7 in the bag-in-box 2 to prevent the fold 27 from being folded back. |
