Abstract

PROBLEM TO BE SOLVED: To enhance assembling properties and disposal properties when reinforcing pillars are formed to corner parts by providing the pillar forming parts inserted in a box main body along the inner periphery thereof and forming reinforcing pillars along with side panels at the cornr parts of a box main body and providing a reinforcing plate equipped with the splicing part connecting the adjacent pillar forming parts. SOLUTION: A packaging box 1 is an assembly of a box main body 10 and reinforcing plates 20. The box main body 10 comprises pasteboard such as a corrugated cardboard sheet and is formed by bending the pasteboard so that side panels 12 are erected from the periphery of a bottom panel 11 and an opening part 13 is provided at an upper part. Each of the reinforcing plates 20 is also formed by bending pasteboard such as a corrugated cardboard sheet into an M-shape having two pillar forming parts 21 and the splicing part 22 connecting them and inserted in the box main body 10 along the inner periphery thereof. The pillar forming parts 21 have the V-shaped outer sides 21A adapted to the side panels 12 of the corner parts of the box main body 10 and form the reinforcing pillars 20 along with two side panels 12. Therefore, if the reinforcing plates 20 are inserted in the box main body 10 along the opposed inner surfaces thereof, the packaging box can be immediately assembled and can house a standing pouch.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a packaging box.

[0002]

2. Description of the Related Art As described in Japanese Patent Application Laid-Open No. Hei 7-315436, a packaging box is provided with a column forming portion integrally and adhered to a side plate constituting a box main body. There is a structure in which a reinforcing column is formed in a portion to improve the compressive strength and to allow a mountain display.

[0003]

In the prior art, the blank sheet of the box body is provided with a column forming portion, and it is necessary to fold up the column forming portion and adhere the column forming portion to the side plate. Disposability is bad because it is used.

[0004] It is an object of the present invention to improve assemblability and disposability when forming a reinforcing column at a corner of a box body.

[0005]

According to a first aspect of the present invention, there is provided a packaging box according to the present invention.
Inserted along the inner circumference of the box body with an opening at the top,
It has a pillar forming part that forms a reinforcing pillar together with a side plate at a corner part of the box body, and a reinforcing plate that has a joint part that connects adjacent pillar forming parts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A packaging box 1 is an assembly of a box body 10 and a reinforcing plate 20, as shown in FIG.

The box body 10 is folded up from a paperboard such as a cardboard sheet, and has a side plate 12 erected around a bottom plate 11 and an opening 13 at the top. The side plate 12 can be formed with a display opening in advance or cut out at the display stage.

The reinforcing plate 20 is bent from a paperboard such as a corrugated cardboard sheet, and has a substantially M-shape including two column forming portions 21 and a joint portion 22 connecting the adjacent column forming portions 21 and 21. , Are inserted along the inner periphery of the box body 10.
The column forming portion 21 has a V-shape connected to both outer edges of the flat joint portion 22, and the outer side 21 </ b> A of the V-shape is attached to the side plate 12 at the corner of the box body 10, Reinforcing column 2 with two side plates 12, 12 intersecting at the corner
To form Since the reinforcing plate 20 has the column forming portion 21 connected and integrated by the joint portion 22, the workability of insertion into the box body 10 and the self-standing stability after insertion are good.

Accordingly, the packaging box 10 is immediately assembled by inserting each of the two reinforcing plates 20 into each of the opposing inner surfaces of the box body 10, and as shown in FIG.
The standing pouch 3 can be accommodated. At this time,
The inner side 21B of the pillar forming portion 21 of the reinforcing plate 20 is inclined with respect to the side plate 12 of the box body 10, and the standing pouch 3 is housed at a high density without any gap so as to follow the inclination of the inner side 21B. There is no movement.

Therefore, according to the present embodiment, the following operations are provided. The reinforcing plate 20 is separate from the box main body 10 and is simply assembled along the inner periphery of the box main body 10 to complete the incorporation. The box main body 10 itself has a simple form and is easy to assemble.

By simply inserting the reinforcing plate 20 into the box body 10, the reinforcing pillars 2 can be formed at the corners of the box body 10,
Good disposability since no adhesive is involved.

The reinforcing plate 20 is inserted along the inner periphery of the box body 10, and the reinforcing plate 2 is provided at the center of the box body 10.
Since no installation space is provided for the box body 10
Can hold the standing pouch 3 at high density inside,
Good article storage efficiency.

Since the reinforcing plate 20 forms the reinforcing columns 2 at the corners of the box body 10, the compressive strength is improved, and the piled-up display is possible. In addition, the reinforcing plate 20 has four ridge lines including a connecting portion between the column forming portion 21 and the joint portion 22 and a fold portion between the outer side 21A and the inner side 21B of the column forming portion 21, and the compressive strength of itself is also strong.

Since the reinforcing plate 20 has an M shape, and the outer sides 21A of the column forming portions 21 on both sides are attached to the side plates 12 at the corners of the box body 10, a lateral displacement force is generated in the reinforcing plate 20. At this time, the outer side 21 </ b> A of the column forming portion 21 abuts against the side plate 12, thereby preventing lateral displacement. Therefore, when the standing pouch 3 is loaded into the packaging box 1, the reinforcing plate 20 is less likely to be laterally displaced.

Since the contents to be packed in the packaging box 1 are the standing pouches 3, the standing pouches 3 made of flexible bags can be stored at a high density without any gaps in the center of the box body 10. The standing pouch 3 has little compressive strength, but can be stored in the packaging box 1 and displayed in a pile.

In the embodiment of the present invention, the reinforcing plate 20
Is a C-shape as shown in FIG.
It may have an S-shape as shown in FIG.

[0017]

As described above, according to the present invention, when reinforcing columns are formed at the corners of the box body, assemblability and disposability can be improved.
