  The packaging box having the above configuration is shipped to a manufacturer of a predetermined product in a blank state, for example, and boxed by an automatic assembly packaging device. Specifically, the products are placed in a predetermined arrangement on the bottom wall portion 10 in a blank state. Then, each wall part 11A, 11B, 13 and the insertion part 15 are bent centering | focusing on the bottom wall part 10, and the insertion part 15 is affixed on the inner surface of the 2nd side wall part 11B with the adhesive agent which consists of a hot-melt resin. (Hot melt). At this time, the sticking region is only the corresponding position of the extraction part 27 and the insertion part 15 of the second side wall part 11B.

  Moreover, after each inner flap 17A, 17B, 18A, 18B is folded, it is folded so that the outer flaps 19A, 19B overlap each other, and these are stuck by hot melt. Similarly, the adhering portions 21A and 21B are bent so as to overlap the surfaces of the inner flaps 17A, 17B, 18A and 18B, and these are adhering with hot melt. Under the present circumstances, the sticking area | region of sticking part 21A, 21B is only the position except the protrusion piece part 23. FIG.

  As shown in FIG. 1, in the packaging box thus manufactured, the first side wall portion 11A, the second side wall portion 11B, the flaps 17A to 19A, and the flaps 17B to 19B each constitute a wall portion. These constitute the peripheral wall surrounding the outer periphery. Then, one (lower) end opening of the peripheral wall is closed by the bottom wall portion 10 which is a closing wall, and the other (upper) end opening is closed by the lid wall portion 13 which is a lid wall. Furthermore, sticking parts 21A and 21B which are sticking walls are stuck to the outer surfaces of the flaps 17A to 19A and the flaps 17B to 19B which are the third and fourth wall parts. That is, the adhering portions 21A and 21B are adhered to the wall portions excluding the side wall portions 11A and 11B which are the first and second wall portions.

  When opening the packaging box, first, the extraction part 27 of the second side wall part 11B is pressed inward from the outside. Thereby, the extraction part 27 is fractured from the side wall part 11 </ b> B along the surrounding third fracture line 26. As a result, the insertion part 15 is in a free state with respect to the side wall part 11B in a state where the extraction part 27 is stuck to the insertion part 15 provided continuously to the lid wall part 13. Next, by pulling up the lid wall portion 13 upward, as shown in FIG. 2, the sticking portions 21A and 21B are broken along the second break line 24A, the first break line 22 and the second break line 24B, The lid wall portion 13 together with the protruding piece portion 23 can be in an opened state that can be bent with respect to the side wall portion 11A.

Thereby, the insertion part 15 acts so that the side wall part 11B may be pressed outward with an elastic restoring force, and can maintain a sealed state by frictional resistance. In addition, in the present embodiment, since the extracted portion 27 is formed in a trapezoidal shape that spreads downward, when the extracted portion 27 is fitted to the break edge by the third break line 26, the lid wall portion 13 is its own. It does not open by elastic force.

  However, the protruding piece portion 23 does not have any member that can be restrained outside. Therefore, the expanded state is maintained by its own elastic force. Therefore, as shown in FIG. 3, when the unsealed packaging boxes are stacked on the resealed packaging box, the elastically raised protrusions 23 can be easily confirmed. It can be easily determined whether or not a box exists.

  FIG. 5 shows a blank of the packaging box of the second embodiment. Although this packaging box applied the structure which has the protruding piece part 43 of this invention to the packaging box of the wraparound type which comprised a part of peripheral wall by flap 17A, 17B-19A, 19B in 1st Embodiment, it is a different type.
