Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a foldable packaging box for long objects.

(Conventional technology) The inventor is not aware of any conventional examples of this type.

Conventionally, elongated metal rods or steel materials, for example, were packaged and transported by appropriately wrapping them in paper or the like, and then bundling them in a certain quantity.

(Problems to be solved by this invention) The problems to be solved by this invention are the complexity of packaging long items, the need for secondary binding work, and the need to protect the items to be packaged. This is not enough.

(Means for solving the problem) A partition with an uneven cross section formed by folding a rectangular sheet on a relatively long and narrow rectangular packaging box main body, which is provided with a foldable lid around the periphery. is provided in the longitudinal direction of the packaging box main body, the adhesive portion on one side of the partition is pasted onto the packaging box main body, and the base sheet is pasted on the adhesive portion on the other side of the partition. This allows long items to be packaged simply by inserting them into a long and narrow storage chamber formed inside the box.

(Operation of the invention) A long and narrow storage chamber with a grid-like cross section is formed by the partition attached between the main body of the packaging box and the base sheet. A long object is packaged by folding a lid attached around the main body inward and fixing the lid with a mounting tape or the like.

(Example) Details of an example of this invention will be described with reference to the accompanying drawings.

As shown in FIG. 1, a relatively long rectangular packaging box main body 10 is provided.

A foldable lid 18 is connected around the main body 10.

On the main body 10 is a partition 12a which is foldable and has a length approximately equal to the length of the main body 10.
is located.

An adhesive portion 14a on one side of the partition 12a is attached to the main body 10 with an adhesive.

On the other hand, a base sheet 16a such as kraft paper is attached to the glue margin 14b on the other side of the partition 12a.

As shown in the figure, the partition 12a of this invention is formed by folding a rectangular sheet and has an uneven cross section.

Therefore, this partition 12a is configured to be foldable.

An embodiment of this invention shown in FIG.
Two layers of 2a are provided.

In order to provide two layers, as shown in FIG. 2, another partition 12 is placed on the base sheet 16a.
A base sheet 1 in which a partition 12b is arranged, a glue margin 14c on one side is pasted on the base sheet 16a, and another partition 12b is separately provided with a glue margin 12d on the other side.
It is attached to 6b.

When the partition layer is configured to have three or more layers, the above configuration may be repeated.

The partitions 12a and 12b of the embodiment of this invention are provided so that both sides (left and right in the drawing) are not open, and as can be seen from FIG. The parts are folded inward towards each other.

The partitions 12a and 12b of this invention are not limited to those whose both sides are not open.

Therefore, a partition 20 with both sides open as shown in FIG. 3 can also be used in this invention.

Further, as for the partitions whose both sides are not open, the partitions 22 and 24 having the structure shown in FIGS. 4 and 5 other than the one shown in FIG. 2 may be used.

In this invention, it is preferable to adopt a partition having a structure in which both sides are not open, and therefore, this is given as an example.

(Effects of the invention) Since this invention has the above configuration, it has the following advantages.

(1) A long and narrow partition is provided on the main body of the packaging box, and a base sheet is pasted on the other side to form a storage chamber for the packaged items. Items to be packaged can be packaged by simply inserting the length item.

(2) Since the partitions are foldable, the entire box can be folded together with the partitions, so when not in use, the box can be folded for storage or transportation without taking up much space, reducing space.

(3) Compared to wrapping with conventional paper, the packaged items can be more reliably protected and the complexity of the packaging work can be eliminated.
