Abstract

PURPOSE: To provide a display box made of cardboard with a display panel attached, having a simple but sturdy construction, allowing a quick and easy assembly, and ensuring low fabrication cost. CONSTITUTION: End walls 3 are formed at the opposite ends of an outer bottom board 10. Also, an outer side board 20, an inner side board 30 and an inner bottom board 40 are sequentially formed at the opposite sides of the board 10. The boards 20 and 30 are superposed to form the side walls 1, and the board 10 and 40 are also superposed to form bottom walls 2. In addition, a folding line is formed over a range from the upper section of the board 30 to the inner bottom board 40, and a free section made of a part of the boards 30 and 40 separated from the side walls 1 and a bottom wall 2, is formed on both sides of at least one of the end walls 3. Also, a display board 70 is projected internally from the upper end of the end wall 3, and both sides of the board 70 has a folding line from the end to form a bending section corresponding to the breadth of the free section. Then, the bending section is folded and engaged with the free section.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cardboard display box provided with a display board.

[0002]

2. Description of the Related Art A conventional cardboard display box of this type preferably has a large display board. In this case, since the display board and the side wall must be connected while securing the area of the display board, the structure is complicated. As a result, the assembly becomes complicated and the display plate is likely to come off, or the structure is simple but the display plate has to be attached by gluing.

[0003]

SUMMARY OF THE INVENTION The present invention provides a display box with a display board made of cardboard, which has a simple structure, is strong, can be assembled quickly and easily, and is inexpensive to manufacture.

[0004]

In order to achieve the above-mentioned object, the display box of the present invention has end walls connected to opposite end edges of an outer bottom plate, respectively, and has outer sides at opposite side edges of the outer bottom plate. A plate, an inner plate, and an inner bottom plate are successively arranged, and an outer plate and an inner plate are overlapped to form a side wall, and an outer bottom plate and an inner bottom plate are overlapped to form a bottom wall. By forming a part of the inner plate and the inner bottom plate separated from the side wall and the bottom wall on both sides of at least one end wall, the display plate from the upper end of the end wall to the inside of the box. The display plate is provided with cuts from both ends thereof to form a bent portion corresponding to the width of the free portion, and the bent portion is folded and engaged with the free portion.

In the present invention, the disengagement portion formed by disengaging a part of the inner plate and the inner bottom plate is for inserting and engaging the bent portions formed on both sides of the display plate. The shape of the part corresponds to the width of the free part, and any shape can be used as long as it can be inserted into and engaged with the free part.

[0006]

EXAMPLE 1 Example 1 of the present invention is shown in FIGS. As shown in FIG. 5, the display box of this example has an outer bottom plate 10
From the opposite side edges of the outer plate 20 and the inner plate 30, respectively.
And the inner bottom plate 40 are successively connected, and the inner bottom plate 40 is arranged from the upper end of the inner plate 30 so that a loose portion 4 described later can be formed.
A notch A leading to is provided. The portion forming the free portion 4 has a fold curve parallel to the side edge of the outer bottom plate 10 at the tip of the cut A and at a position separated from the height of the box by this. One end of the inner bottom plate 40 is slightly cut away. Further, the outer end plate 60 and the display plate 70 are sequentially connected to one edge of the outer bottom plate 10, and a cut B for forming a bent portion 5 described later is formed on both sides of the display plate 70. Is provided. The portion forming the bent portion 5 has a bending curve parallel to the edge of the outer bottom plate 10 at the tip of the cut B and at a position separated from the free portion 4 by the width thereof. The bent portion 5 is divided into two parts 51 and 52 by these bending curves. Further, an outer end plate 60, an inner end plate 80, and a folding plate 90 are sequentially connected to the other edge of the outer bottom plate 10. The outer plates 20 and the outer end plates 60 are connected by the folding pieces 50. Furthermore, free part 4
The two folding curves provided on the folding part 5 and the folding part 5 are not necessarily required because they are made of cardboard, but these folding curves facilitate the assembly of the box.

Therefore, as shown in FIGS. 2 and 1, the outer side plate 20 and the inner side plate 30 are overlapped to form the side wall 1 and the outer bottom plate 10.
And the inner bottom plate 40 are overlapped with each other to form the bottom wall 2,
The cut portions A provided on the inner plate 30 and the inner bottom plate 40 and the portion sandwiched by the outer end plate 60 are separated from the bottom wall 2 and the side wall 1 to form each loosened portion 4. While folding each folding piece 50 toward the end wall 3, the outer end plate 60 at one edge of the outer bottom plate 10 is erected so that the display plate 70 projects inward from the upper end of the outer end plate 60 (end wall 3). Then, the bent portions 5 having two bending curves are inserted into the loose portions 4 and engaged with each other. Further, the outer end plate 60 and the inner end plate 80 at the other end edge of the outer bottom plate 10 are overlapped with each other to form the end wall 3, and the folding plate 90 is used as the inner bottom plate 4.
It can be assembled by fitting it into the notch of 0 and fixing it. At this time, since the 51 part of the bent part 5 is abutted and fixed so as to press the back side of the loose part 4 and the 52 part to the folding piece 50, the box corner is more firmly fixed.

[0008]

According to the present invention, each side wall and end wall are erected and the free portion is floated, and the bent portions provided on both sides of the display plate are inserted into and engaged with the display portion. The attached display box can be assembled quickly and easily, can be manufactured at low cost, and is suitable for displaying products. Further, since the bent portion is engaged in a width corresponding to the width of the free portion, it can be firmly fixed and is structurally strong. Further, since the product is stored in contact with the loose portion, the product is not easily obscured by the display plate.
