Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packaging box for storing or storing various products.

[0002]

[Prior art]

 Conventionally, a relatively flat rectangular box with an open upper surface has connecting pieces installed at both ends of side plates that form four side surfaces inside the adjacent side plates, so that each side surface stands up. Was held. This side plate and connecting piece assembly work must be done manually because the connecting piece must be bent inward and inserted into the gap between the adjacent side plate and folded piece.

[0003]

[Problems to be solved by the device]

 In the case of the conventional technique described above, the work of bending the connecting piece inward and inserting it into the gap between the adjacent side plates requires skill and requires a lot of man-hours. Moreover, since it cannot be automated, even a simple box costs a lot to manufacture, and usually the boxes are assembled when packing the products, which is an obstacle to reducing the number of man-hours when packing.

The present invention has been made in view of the above problems of the conventional technique, and an object thereof is to provide a packaging box having a simple structure and easy to assemble.

[0005]

[Means for Solving the Problems]

 In this invention, a side plate is provided inside the box, each side plate having a folded piece, and the side plates adjacent to each other on both sides of the folded piece of the pair of side plates facing each other. It is a packaging box provided with connecting pieces of such a size as to cover both end portions of a face plate.

[0006]

[Action]

 In the packaging box of this invention, since the pair of side plate side connecting pieces are hooked on the end portions of the adjacent side plate during assembly, the connecting pieces are automatically made adjacent to each other by raising each side plate. It is located on the inner side of the side surface, eliminating the work of holding the connecting piece in place.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The packaging box of this embodiment is formed by punching out a blank sheet, and is composed of side plates 10, 12, 14, 16 and a bottom face 18 as shown in the drawing, and is provided at both ends of the side plates 12, 16. Connecting pieces 20, 22, 24 and 26 are formed. Further, folding pieces 28, 30, 32, 34 are formed on the side plates 10, 12, 14, 16, respectively, and connecting pieces 36, 38 are provided at both ends of the folding pieces 28, 32 of the side plates 10, 14, respectively. , 40, 42 are formed.

The side plates 10, 12, 14, 16 and the bottom face 18 are separated by folding lines 11, 13, 15, 17 respectively, and the side plates 10, 12, 14, 16 and the folded pieces 28, 30 are separated from each other. , 32, 34 are separated by folding ruled lines 21, 23, 25, 27. In addition, crease lines 31, 33, 35, 37 are formed between the side plates 12, 16 and the connecting pieces 20, 22, 24, 26. Further, folding ruled lines 41, 43, 45, 47 are formed between the folding pieces 28, 32 and the connecting pieces 36, 38, 40, 42.

Glued portions 50 and 52 are formed on the back surfaces of the side plates 10 and 14, and the connecting pieces 28 and 32 are folded back and glued. The back surfaces of the side plates 12 and 16 are also glued. The hook portions 54 and 56 are formed, and the connecting pieces 30 and 34 are folded back and glued. Further, the bottom plate 18 is provided with projections 58 which are formed in a lattice shape so as to be slightly convex on the bottom side of the box, that is, on the back side of the paper surface.

Next, a method of assembling the packaging box of this embodiment will be described with reference to FIGS. Here, FIG. 1 is viewed from the back surface side of the blank sheet of this packaging box, and the folding method in which the back surface side of the paper surface in FIG. 1 is convex is called normal folding, and the opposite is called reverse folding. First, the glue 60 is applied to the glued portions 50 and 52 on the back surfaces of the side plates 10 and 14, and the folded pieces 28 and 32 are normally folded along the folding lines 21 and 25. Next, as shown in FIG. 2, glue 60 is applied to the gluing portions 54 and 56 on the back surfaces of the side plates 12 and 16, and the folding pieces 30 and 34 are normally folded along the folding lines 23 and 27.

Then, from the state shown in FIG. 3, the side plates 10, 12, 14, 16 are folded up along the folding lines 11, 13, 15, 17 in a normal direction. Then, the connecting pieces 36, 38, 40, 42 have their tip portions folded over to the folding ruled lines 31, 33, 35, 37 at both ends of the side plates 12, 16 as shown in FIG. As shown in FIGS. 4 and 5, the connecting pieces 36, 38, 40 and 42 are automatically inserted between the adjacent side plates 12 and 16 and the folding pieces 30 and 34, respectively. Further, when the connecting pieces 20, 22, 24, 26 provided at both ends of the side surface plates 12, 16 are pressed against the facing connecting pieces 36, 38, 40, 42, respectively. And the folded pieces 30, 34 are easily inserted into the gap.

According to the packaging box of this embodiment, when assembling the box body, the connecting pieces 36, 38, 40, 42 are automatically moved to the side plates 12 by simply raising the side plates 10, 12, 14, 16. , 16 and the folding pieces 30, 34, the box assembly can be easily assembled automatically. Further, since the packaging box of this embodiment is provided with the protrusion 58 which is slightly convex on the back side, the entire bottom face portion does not slide on the installation surface such as a table, and the protrusion 58 is provided. Only the contact with the table surface makes it easy to move the packaging box, etc.

In the packaging box of the present invention, in addition to the above embodiment, the side plates 10, 12, 14, 16 are reverse-folded at the folding ruled lines 11, 13, 15, 17 from the state shown in FIG. You may do it. In this case, the connecting pieces 20, 22, 24, 26 do not need any guide and can be easily inserted into the gap between the side plates 10, 14 and the folding pieces 28, 32. Further, the connecting pieces 36, 38, 40, 42 are automatically inserted between the adjacent side plates 12, 16 and the folding pieces 30, 34, as in the above-described embodiment. Therefore, in this case, the holding operation of the connecting pieces 20, 22, 24, 26, 36, 38, 40, 42 is not necessary at all, and the assembling work is greatly improved.

[0014]

[Effect of device]

 In the packaging box of this invention, the connecting piece is formed so as to securely and automatically enter the inside of the adjacent side plate, so that the box can be easily assembled and the box assembly can be easily automated. It is possible. Moreover, since the structure is simple and mass production is possible, a large number of packaging boxes can be provided at low cost.
