DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging box in which goods and the like housed therein are displayed without opening the cover paper in a state where the boxes and the like are stacked, and the goods and the like can be taken out and sold. (Corrugated fiber board box).

[0002]

2. Description of the Related Art FIG. 12 is a perspective view showing a conventional corrugated cardboard.
07 and 108 are adhered by an adhesive. Conventionally, the packaging box shown in FIG. 13 has been manufactured using the cardboard thus configured. That is, as shown in FIG. 13, a conventional packaging box has a flipper (flip)
per) 114 is integrally formed, the flipper 114 is bonded to the tetrahedral cardboard 112 with an adhesive, and the upper and lower lids are folded to produce a box.

[0003]

A packaging box made of cardboard as described above has been transported or stored after covering a large number of small-packaged products, and then covering a cover paper or the like. Therefore, there is an inconvenience that the cover paper of the packaging box must be opened at the time of displaying or selling the products and the like contained in the packaging box.

[0004] In addition, in order to take out the product from the packaging box, a space for separately installing a display stand is required at the sales floor, which requires a separate installation cost for installing the display stand. Cannot be stacked and placed on the sales floor, so a separate storage space is required for the packaging boxes, which in turn requires additional costs for displaying the products and storing the packaging boxes. There was a problem.

[0005] In the conventional packaging box, cardboard is interposed between the inner and outer flat papers. In particular, the outer surface of the outer flat paper has a weak cushioning force, so that there is a problem that the outer flat paper is easily damaged. In addition, conventional packaging boxes have a smooth outer surface to prevent the outer flat paper from being damaged.However, such a box slips when a person lifts, transports, or stacks many boxes. Therefore, the handling is extremely inconvenient, and when the stacked boxes collapse, there is a problem that not only the packaging boxes are damaged, but also the goods contained in the boxes and other peripheral articles are damaged.

Furthermore, in the conventional packaging box, glue (adhesive) must be attached to the flipper 114 when it is folded into a tetrahedron. Generally, the glue is not constant in viscosity and the amount of glue is not sufficient. Not constant. Therefore, if a large amount of gluing is performed because the viscosity of the glue is low, the surface to which the flipper 114 is connected and the adjacent surface are bonded, and when used by a consumer, the automatic machine may open the box. In addition, when a product is automatically inserted into a packaging box by forming a protruding portion inside or outside the thickness of the flipper 114, the product is pushed in when the packaging box is lying down. There is a problem that the product is caught on the flipper that has been moved. For this reason, in the case of automating the pushing of the product, if a problem occurs in the previous box, the product cannot be continuously pushed into the next box, and the packaging operation is interrupted.

For a conventional packaging box, see US Pat.
252,236. The packaging box disclosed in this specification is provided with a cutout from the top surface (cover paper) of the box to the front wall, and such a packaging box has a cutout at the corner of the box. Therefore, when a large number of boxes are stacked, notches are easily broken by impact or pressure, and there is also a problem that the notches can be broken by small impact when the boxes are moved.

Accordingly, the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a packaging box capable of preventing damage and preventing slippage. .
