  When this packaging box 10 is used, first, the lower inner flaps 18A and 18B constituting the bottom surface are folded inward with respect to the end walls 12A and 12B along the folding line 20, and then the lower The side outer flaps 19A and 19B are bent with respect to the side walls 13A and 13B. Then, the lower outer flaps 19A and 19B which are butted against each other are fixed with an adhesive tape. Alternatively, the overlapping portions of these flaps 18A, 18B, 19A, 19B are fixed by a known fixing metal fitting.

  Next, in a state where the upright portion 26 and the bent portion 27 extending in a planar manner are superimposed on the end wall 12B, a predetermined product is received from the opened upper end opening. Thereafter, the upper inner flaps 16A and 16B constituting the top surface are bent inward with respect to the end walls 12A and 12B along the folding line 20, and the upper outer flaps 17A and 17B are then bent with respect to the side walls 13A and 13B. Bend them and fix them with adhesive tape or fixing hardware.

  As shown in FIG. 1, the sealed packaging box 10 is provided only with a break end 22 for breaking the end wall 12A, 12B and the side walls 13A, 13B surrounding the outer periphery with a resin tape 21. In addition, no break line or folding line is provided for providing the display unit 25. Therefore, the packaging box 10 hardly deteriorates in compressive strength when stacked, as well as rigidity. Therefore, it can be suitably used as a packaging box 10 for transportation.

  On the other hand, in a store that sells products stored in the packaging box 10, first, a finger is inserted into the broken end portion 22 provided on the side walls 13A and 13B, and the end piece surrounded by three cutting lines is gripped. Pull. Thereby, the side walls 13A and 13B and the continuous end walls 12A and 12B can be broken so as to be torn with the resin tape 21. At this time, the display unit 25 is not broken by the resin tape 21 by the second cutting unit 40 as described above.

  In this way, when all the walls 12A, 12B, 13A, 13B including the adhesive margin 14 are broken up and down, as shown in FIG. 2, the upper box portion 10a on the upper side and the state in which the commodity is accommodated are maintained. It is separated into a lower lower box portion 10b.

  In this state, as shown in the figure, the lower box portion 10b has a state in which the display portion 25 connected to the adhesive margin portion 14 extends upward along the end wall 12B while being sealed, and protrudes upward from the breaking edge. Eggplant. In this state, as shown in FIG. 3, the bent portion 27 is bent so as to protrude outward from the end wall 12 </ b> B together with the attached folding display portion 32.

  Thereby, the folding display part 32 which stuck the back paper 3 side to the bending part 27 positions the cover 2 side on which the advertisement at the time of sale is printed upward. Further, the latch receiving portion 43 of the folding display portion 32 is elastically locked to the latching portion of the upright portion 26, and the folded display portion 32 is bent at a predetermined angle via the bending portion 27.

  Thus, in the packaging box 10 of this invention, since the display part 25 is connected with the glue margin part 14, the rigidity and compressive strength in a sealing state are not impaired. Further, when the display unit 25 is set in the display state, the end walls 12A and 12B, the side walls 13A and 13B, and the adhesive margin part 14 are broken by the resin tape 21 to separate the upper box part 10a, and the bent part 27 is interposed. Since the folding display section 32 is simply bent at a desired angle, the workability is very good.

  Further, in this display state, since the folded display portion 32 protrudes from the end wall 12B with the printing surface facing upward, it is possible to attract the attention of consumers. As a result, appeal to the consumer can be obtained from the advertisement content of the return display unit 32. And since the upper surface of the folding display part 32 exposed in a display state is the same surface as the surface of the packaging box 10, the display based on the product printed on each wall 12A, 12B, 13A, 13B, and the display part 25 The advertisement at the time of sale to be printed on may be printed only on the cover 2. Therefore, the manufacturing cost can be reduced.

  And since the fracture | rupture edge by the resin tape 21 is in the state which was torn, its external appearance is not good at all, but the fracture | rupture edge can be covered by the bending of the folding | turning display part 32. FIG. As a result, it is possible to prevent a decrease in the willingness to purchase due to poor appearance.
