Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging case suitable for packaging lighting equipment.

[0002]

2. Description of the Related Art Conventionally, it is known that both side plates formed of a sheet are folded inward to form some cushioning body for protecting a packaged article.

[0003]

However, there has been a problem that the bottom of the packaged article is not sufficiently protected. An object of the present invention is to solve the above problems and to sufficiently protect the bottom of a packaged article. Other purposes will be apparent from the following description.

[0004]

SUMMARY OF THE INVENTION According to the present invention, both side plates formed of a sheet are folded inward to form a tubular body, which is cut and raised from the inner side plate of the tubular body to the bottom plate of the seat. A packaging case having an inner bottom plate positioned therein is constructed. Further, in this configuration, the ends of both inner bottom plates form a packaging case in which they are substantially butted. Furthermore, the packaging case is provided with a tubular shape retaining plate that is fitted into the hollow portion of the tubular body by bending the tubular body from both ends. Further, flaps are formed on the bottom plate and other side plates extending in a direction orthogonal to the direction in which the cylinder is formed, and these flaps are folded inward, respectively, and the flaps constitute a packaging case that overlaps the top surface of the top plate of the cylinder. .

[0005]

According to the present invention, since the inner bottom plate positioned on the bottom plate of the sheet is formed by cutting and raising the inner plate of the tubular body inward, the bottom of the packaged article can be sufficiently protected. Also,
When the ends of both inner bottom plates are substantially butted, the distance between the two cylinders is regulated, which facilitates the packaging work. Furthermore, the tubular shape retaining plate contributes to maintain the shape of the tubular body, facilitates the packaging work, and makes the packaging case firm. Also, when the bottom plate forms flaps with the other side plates extending in the direction orthogonal to the forming direction of the cylinder and these flaps are folded inward, the cylinder shape retaining plate is pushed by the other side plates. Since it can be semi-automatically fitted into the hollow portion of the cylindrical body, the packaging work becomes easy.

[0006]

Embodiments of the present invention will be described with reference to the drawings.

In this embodiment, both side plates formed of a sheet of corrugated cardboard or the like are folded inward to form a cylindrical body 1, and the inner bottom plate 2 of the cylindrical body 1 is cut and raised toward the inner side to form a bottom plate 3 of the sheet. A packaging case in which the inner bottom plate 4 located above is formed. Further, in this structure, the ends of both inner bottom plates 4 constitute a packaging case in which they are substantially butted. A is a packaged article such as a lighting fixture, and B is an accessory such as a lamp.

More specifically, for example, the top plate 5 of the cylindrical body 1
A cylindrical shape-retaining plate 6 which is fitted into the hollow portion of the cylindrical body 1 by being bent from both ends and contributes to maintain the shape of the cylindrical body 1 is provided. A bridge-shaped support plate 7 is formed on the top plate 5 of one of the cylinders 1 by cutting and raising it downward.
Supports accessory B. The packaged article A is placed on the inner bottom plate 4 through the holes 8 formed in the inner plate 2 by cutting and raising the inner bottom plate 4, but it is not passed through the holes 8 and both inner plates 2, It may be located between two. The bottom plate 3 includes another side plate 9 and a flap 1 extending in a direction orthogonal to the forming direction of the tubular body 1.
0 is formed and they are folded inward, respectively, and the flap 10 overlaps the top surface of the top plate 5 of the cylinder 1. Flap 10,
The packaging is completed by fixing 10 and the tubular body 1 to each other with an adhesive tape or other appropriate means. It is also possible to form the cylindrical body 1 and the bottom plate 3 from separate sheets and then fix them to each other with a staple or the like. Further, even if the tubular body 1 is formed independently of the packaging case and is housed in the packaging case as an internal cushioning body, the gist of the present invention is not impaired.

According to this embodiment, since the inner bottom plate 4 located on the bottom plate 3 of the sheet is formed by cutting and raising the inner plate 2 of the tubular body 1 inward, the bottom of the packaged article A is sufficiently protected. You can Further, when the ends of the inner bottom plates 4 are substantially abutted with each other, the interval between the two cylinders 1 is regulated, which facilitates the packaging work. Furthermore, the tubular shape retaining plate 6 contributes to maintain the shape of the tubular body 1, which facilitates the packaging work and makes the packaging case firm. Further, when the other side plates 9 and the flap 10 extending in the direction orthogonal to the forming direction of the tubular body 1 are formed on the bottom plate 3 and they are respectively folded inward,
Since the tubular shape retaining plate 6 can be pushed into the hollow portion of the tubular body 1 by being pushed by the other side plates 9 and semi-automatically, the packaging work becomes easy.

[0010]

As described above, according to the present invention, there is an effect that the bottom of the packaged article can be sufficiently protected according to each claim, the packaging work is facilitated, and the packaging case is solid. .
