Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a packaging box with internal partitions that is easy to assemble and open.

<Prior art> Various types of boxes have been proposed in the past, each of which has partitions inside the box to divide the storage area and store multiple items. There are two types: single-piece type, in which all the members are formed in one blank.

The former is composed of, for example, a box body, a lid, and a partition member, and has the problem of requiring a lot of time and effort to assemble and increasing costs. In addition, in the latter case, the overall structure is complicated because the parts are combined into one,
It has the disadvantage of poor productivity.

<Problem to be solved by the invention> The present invention was made to solve the above-mentioned drawbacks of the conventional technology, and consists of a single member,
The purpose is to present a packaging box with partitions that has a simple structure and good productivity.

<Means for Solving the Problems> In other words, the packaging box of the present invention is composed of a back plate, a symmetrical partition cylinder formed on the back plate, and an outer jacket formed to cover the top of the partition cylinder. The back plate and the inner partition cylindrical body are pasted together in advance and folded flat before use, and when used, the inner partition cylindrical body is raised and each tongue piece of the outer mantle is locked. Assembly is completed by simply inserting it into the groove.

<Example> Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a developed view of the packaging box of the present invention. There is a back plate 1 in the center, and a fold 9'' is provided at the top center to act as a hinge when opening and closing the box.At the left and right ends of the back plate 1 are side plates 2, 2. ', a front plate 3, 3' and a side plate 4, 4' are provided in this order, and a glue plate 5 for fixing to the rear plate by applying glue to the end of the side plate 4, 4'.
5' is provided. The glue plates 5, 5' have a fold 1 corresponding to the position of the fold 9'' provided on the back plate 1.
6 and 16' are provided, respectively. Furthermore, four locking grooves 15, 15' into which tongue pieces 14 are inserted are formed at the upper and lower parts of the side plate side of the boundary between the back plate 1 and the side plates 2, 2'. Further, opening perforation lines 9, 9' are connected to cutting lines 8, 8' to be described later on the side plates 2, 2' to open the packaging box up and down. The face plates 4, 4' are provided with cut lines 8, 8' for opening the packaging box vertically, and upper flaps 6, 6' and lower flaps 7, 7' are provided above and below the side plates 2, 2'. is provided. A top plate 10 and a bottom plate 10' are provided above and below the back plate 1, and front plates 11 and 11' are provided in this order, and left and right side plates 12 and 1 are provided on the left and right sides of the front plate 11 and 11'.
2', 13, 13', and the side plates 12, 1
A tongue piece 14, 14' is provided at one end of 2', 13, 13'.

Next, assembly will be explained. As shown in FIG. 2, a side plate 2, a front plate 3, a side plate 4, a side plate 5, a side plate 2', a front plate 3', a side plate 4',
Fold the surface with the glue plate 5′ inward, and
Apply glue to the back side of 5' and fix it to the back plate 1.
The inner partition cylinders are called A and A'. At this stage, fold it flat and store it. Then, at the final assembly stage,
The upper flaps 6, 6' and the lower flaps 7, 7' are bent inward to create a thicker bottom. Next, a surface having a top plate 10 and a front plate 11, a bottom plate 10',
Fold the surface having the front plate 11' and overlap it on the inner partition cylinder as shown in FIG. 3, and lock the left and right tongue pieces 14, 14' in the left and right locking grooves 15, 15', respectively. The assembly of the packaging box is completed by forming the outer envelopes B and B'.

FIG. 4 is a schematic diagram of the assembled packaging box. The front plates 11 and 11' are located at the front, the top plate 10 is located at the top, and the left and right side panels 13 and 13' are located at the right side.

FIG. 5 is a schematic view of the assembled packaging box opened. the side plates 2, 2', the front plate 3,
3', the side plates 4, 4' form a cylindrical partition inside the box, and when the opening perforation lines 9, 9' are broken, the cutting lines 8, which are connected to the opening perforations 9, 9' and which have been cut in advance, 8′ divides the inner partition tube into upper and lower parts.
The fold 9'' provided on the back plate 1 and the folds 16, 16' provided on the glue plates 5, 5' are hinged to form a structure that can be opened and closed.

<Effects of the invention> Since the invention is as described above, it produces the following effects.

In other words, two partition cylinders A from one sheet of paperboard,
A packaging box having A' is obtained, which can be stored without bulk by being folded flat until the time of use, and can be easily assembled at the time of use. The packaging box of the present invention is an extremely convenient box that can be opened with one touch.
