Description

[Detailed description of the invention] This invention relates to a partition material for packaging boxes.

Conventionally, as a partition material that fits into a rectangular parallelepiped packaging box to separate multiple items, it is made by combining a rectangular vertical partition plate with an upward cut and a rectangular horizontal partition plate with a downward cut. There are also popular types that consist of a vertical partition plate with an upward or downward cut, and a horizontal partition plate with a substantially U-shaped cross section that has side plates connected to the bottom plate and meshes with the vertical partition plate.

However, the former has the disadvantage that it is difficult to maintain the vertical and horizontal partitions in a perpendicular state, whereas the latter has a bottom plate that makes it difficult to maintain the vertical and horizontal partitions in a perpendicular state and prevents them from wobbling inside the packaging box. Although it has the advantage of being stable and stable, it has the disadvantage that the amount of material used for the bottom plate increases compared to the former partition material, resulting in higher costs.

The purpose of this invention is to eliminate the above-mentioned drawbacks.

That is, this invention consists of a rectangular vertical partition plate with a notch that opens upward, and a horizontal partition plate with a substantially U-shaped cross section in which opposing rectangular side plates are connected from the bottom plate. In a packaging box partition material in which a series of cuts are formed in a plate and a bottom plate and mesh with the cuts in the vertical partition plate, the engagement between the cuts in the vertical partition plate and the cuts in the horizontal partition plate is such that the cuts in the horizontal partition plate are engaged with each other. This is a packaging box partition material that can hold a bottom plate suspended in the air and is provided with a separation line that allows the bottom plate to be divided.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

1 and 2 are a perspective view and a front view of a vertical partition plate showing a first embodiment of this invention. This partition material is made of base paper such as corrugated cardboard, and has a rectangular vertical partition plate 2 with a pair of vertical cuts 1 provided in the upper half to divide the area into three equal parts, and an opposing rectangular side plate 3 that is connected through a fold line 7. A cross section approximately U connected from the rectangular bottom plate 4
As shown in FIG. 3, a series of notches 6 are formed in the center of the lower half of the side plates 3 of the horizontal partition plate 5 and in the center of the bottom plate 4 to form a vertical partition plate. 2, and is engaged with the vertical notch 1 of the bottom plate 4.
The width is the same as the distance between the vertical cuts 1 of the pair of vertical partition plates 2, and the bottom plate 4 is provided with a separation line 8 such as a perforation parallel to the fold line 7 in the center.

The height of the side plate 3 of the horizontal partition plate 5 is equal to that of the vertical partition plate 2.
It is formed to be shorter than the height by the required length l,
In addition, since each cut is provided so that the upper edges of both plates are aligned when engaged with the vertical partition plate 2, the bottom plate 4
is suspended above the lower edge of the vertical partition plate 2 by a length l. This length l is formed to approximately match the length of the half piece 4' (see the chain line in FIG. 1) of the bottom plate 4 divided into two by the separation line 8.

As shown in the development view shown in FIG. 3, the horizontal partition plate 5 is easily bent and formed from a single patterned rectangular substrate a, and is a conventional partitioning material substrate a' ( (see dashed line) requires less material.

The vertical partition plate 2 is provided with a notch 10 that forms a semicircular curved upper edge 9 between the pair of vertical notches 1 . This facilitates the mating insertion of the horizontal partition plates 5 of the vertical partition plates 2.

As shown in FIG. 4, the partition material of the first embodiment is as follows:
When inserted into a rectangular parallelepiped packaging box A with an open top, the bottom plate 4 of the horizontal partition plate 5 is separated from the bottom of the packaging box A by an upward length l and floats in the air. When dropped onto the bottom plate 4, the separation line 8 is cut by its own weight, and as shown in FIG. 5, the divided half pieces 4' of the bottom plate 4 hang down from the lower edge of the side plate 3 and separate the items. .

6 and 7 are a perspective view and a developed view of a horizontal partition plate showing a second embodiment of this invention. The horizontal partition plate 15 used as this partition material has legs 11 at the lower end, and opposing side plates 13 at the same height as the vertical partition plate 2 are connected at both ends by a pair of bottom plate pieces 14 via a fold line 17. It is something that

The width of this bottom plate piece 14 is formed to be approximately the same as the interval between the pair of vertical notches 1 of the vertical partition plate 2.
A notch 16 is provided at the center of the lower half portion to mesh with and abut the vertical notch 1 of the vertical partition plate 2. The bottom plate piece 14 has a fold line 20 parallel to the fold line 17 in the center, and a tear line 18 on one of the fold lines 17.
is formed. As shown in the developed view in FIG.
In between, there is no wastage of materials, and the amount of materials used is smaller than, for example, the board b' of a conventional horizontal partition material whose bottom plate is in contact with the bottom of the packaging box A (see the chain line in Figure 7). I'm done.

As shown in FIG. 8, when the partition material of this second embodiment is fitted into the packaging box A, the bottom plate piece 14 of the horizontal partition material 15 is released from the bottom surface of the packaging box A and floats in the air. When an item is dropped onto this bottom plate piece 14, the separation line 18 is cut by its own weight, and as shown in FIG. ), and the side plate 13
The tongue piece 14' hangs down from the lower end of the tongue piece 14' so that the item can be placed on top of the tongue piece 14'.

This is effective when the height of the partition material is lower than the height of the packaging box A, and has the effect of preventing the partition material from floating up by placing the item on the stand piece 14'. Note that if the above effect is not required, a tear line may be provided above the fold line 20, for example.

The packaging box partition material according to this invention has the above-mentioned structure, and when used, it has a bottom plate or bottom plate piece, so the molding is stable.
The vertical partition plate and the side plates of the horizontal partition plate are maintained perpendicular to each other. Therefore, it has the effect of making it easier and more reliable to insert the item into the packaging box, and because the bottom plate or bottom plate piece is suspended from the bottom of the packaging box and cut when the item is inserted, there is no wastage of materials. This has the effect of reducing costs without any problems.
