The best mode for carrying out the present invention will be described below with reference to the drawings.
In FIG. 1, the packaging box by this invention is expand | deployed and shown.

  The packaging box according to the present invention is made by assembling the rectangular cardboard sheets shown in FIG. Reference numeral 10 in the figure denotes four side plates that are provided so as to face each other. The four side plates 10 are configured by alternately connecting two first side plates 10A facing each other and the remaining two second side plates 10B facing each other in order. In the illustrated example, the first side surface 10A is formed in a square shape, and the second side surface 10B is formed in a horizontally long rectangular shape. A hook 11 serving as a margin is provided on the open side edge of the end second side plate 10B.

  The two first side plates 10A are each provided with a horizontally-long rectangular upper surface flap 12 that is foldable along a horizontal fold line a on the upper side. In each upper surface flap 12, in this example, it is cut into a U-shape and cut pieces 13 are formed one by one for each flap, and the cut pieces 13 are bent by a cause line provided on the horizontal folding line a. It can be caused freely. A finger insertion hole 14 having an appropriate shape is provided at the tip of each cut piece 13. In this example, the finger insertion hole 14 is provided in the cut piece 13 itself, but may be provided around the cut piece 13.

  On the other hand, horizontally long rectangular upper outer flaps 15 are connected to the two second side plates 10B so that they can be bent along the horizontal folding line b on the upper side. In this example, each upper outer flap 15 is also cut into a U-shape to form one incision piece 13 for each flap, and the incision piece 13 is bent by a cause line provided on the horizontal folding line b. It can be caused freely. Similarly, a finger insertion hole 14 having an appropriate shape is provided at the tip of each cut piece 13. In this example, the finger insertion hole 14 is provided in the cut piece 13 itself, but may be provided around the cut piece 13 in the same manner. In these two upper surface outer flaps 15, an insertion hole 16 through which the cut piece 13 of the upper surface inner flap 12 easily passes is formed in the side edge on the upper surface inner flap 12 side.

  On the other hand, the two first side plates 10A are each provided with a horizontally-long rectangular lower surface inner flap 17 that is foldable along a lower horizontal fold line c. The two second side plates 10B are each provided with a horizontally long rectangular outer lower flap 18 that can be bent along a horizontal folding line d on the lower side.

  By the way, in the packaging box of this illustrated example, the insertion holes 20 are formed in the two first side plates 10A along the horizontal folding line c on the lower side. Further, insertion holes 20 are formed in the two second side plates 10B along the horizontal folding line d on the lower side.

The upper inner flap 12 is bent at the horizontal folding line a, the upper outer flap 15 is bent at the horizontal folding line b, the lower inner flap 17 is bent at the horizontal folding line c, and then the horizontal folding is performed. The lower outer flap 18 is bent along the line d and assembled as shown in FIG. In the state shown in FIG. 2, the cut pieces 13 are not raised, so that they do not get in the way when the packaging box is carried alone.

  Next, when the upper surface outer flap 15 is overlapped with the upper surface inner flap 12, the cut piece 13 formed in the upper surface inner flap 12 becomes a position corresponding to the insertion hole 16 formed in the upper surface outer flap 15.

  Such packaging boxes contain products such as printers, copiers, and facsimiles. Thereafter, a finger is put into the finger insertion hole 14 and a fingernail is put on the notch piece 13 formed in the outer flap 15 on the upper surface, and the notch piece 13 is bent by a trigger line, and the finger is inserted into the finger insertion hole 14 through the insertion hole 16. 3 is put on the notch piece 13 formed on the inner flap 12 on the upper surface, bent by a trigger line, and the notch piece 13 is caused to pass through the insertion hole 16 of the outer flap 15 on the upper surface to obtain the state shown in FIG.

  Then, as shown in FIG. 4, when the same packaging box 200 is stacked on the packaging box 100 with the cut pieces 13 being raised, the cut pieces 13 of the lower packaging box 100 are inserted into the insertion holes of the upper packaging box 200. When the upper packaging box 200 is loaded on the lower packaging box 100, the cut piece 13 of the lower packaging box 100 enters the insertion hole 20 of the upper packaging box 200 without large backlash. In the illustrated example, the packaging boxes are stacked in two stages, but it is of course possible to stack the packaging boxes in three or more stages by causing the cut pieces 13 of the upper packaging box 200.

  Thereby, the cut piece 13 and the insertion hole 20 are provided in the packaging box itself, and it is not necessary to provide the fitting convex portion and the fitting concave portion in the cushioning material as in the conventional case. It is possible to reduce the material cost without reducing the effect and without using a large cushioning material. Further, when stacking the packaging boxes, the folding lines are bent to cause the cut pieces 13, the packaging boxes are loaded, the cut pieces 13 of the lower packaging box 100 are put into the insertion holes 20 of the upper packaging box 200, and stacked in order. The cut piece 13 can be inserted into the insertion hole 20 to ensure positioning during loading, and a packaging box that does not collapse due to misalignment can be provided.

  Further, according to the illustrated example, when stacking the packaging boxes, the folding line is bent to cause the cut piece 13 of the upper outer flap 15 and the cut piece 13 of the upper upper flap 12 also passes through the insertion hole 16 of the upper outer flap 15. Therefore, the cut piece 13 provided in the upper surface inner flap 12 can be caused without being obstructed by the upper surface outer flap 15. Then, since the packaging boxes are loaded and the cut pieces 13 of the lower packaging box 100 are put into the insertion holes 13 of the upper packaging box 200 and are stacked in order, loading is performed as compared with the case of only the cutting pieces 13 of the upper outer flap 15. It is possible to provide a packaging box in which the positioning at the time is further ensured and does not collapse due to the positional deviation.

  Any number of the cut pieces 13 can be provided. However, if one piece is formed for each flap on the upper surface outer flap 15 and the upper surface inner flap 12 as shown in the illustrated example, the number of the cut pieces 13 is increased and the configuration is complicated. In addition, when stacking the packaging boxes, the cut pieces 13 formed one by one for each flap are put into the insertion holes 20 of the upper packaging box 200 and stacked sequentially, so that the positioning at the time of loading is even and more It is possible to provide a packaging box that is reliable and does not collapse due to misalignment.

  By the way, in the packaging box of the illustrated example, the cause line of the cut piece 13 is provided on the lateral folding lines a and b of the upper surface outer flap 15 or both of the upper flap 12 and the upper inner flap 12, so that when the packaging boxes are stacked, the lower packaging While looking at the cut pieces 13 of the box 100, the cut pieces 13 are put into the insertion holes 20 of the upper packaging box 200 and stacked in order, so that the insertion of the cut pieces 13 into the insertion holes 20 can be simplified to provide a packaging box that can be easily stacked. it can. In addition, a cut piece 13 is formed at an appropriate position on the upper outer flap 15 of the lower packaging box, and the cut piece 13 is put in an insertion hole formed in the lower outer flap 18 of the upper packaging box and stacked in the upper and lower stages. The box can also be positioned.

  The notch piece 13 itself or around the notch piece 13 is provided with a finger insertion hole 14 for putting a finger when the notch piece 13 is raised and placing the finger on the notch piece 13, and when the notch piece 13 is caused, Since a finger is put in the insertion hole 14, a finger is put on the cut piece 13, it is raised, bent by a line and pulled up, the cut piece 13 can be easily raised when stacked.
