Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cardboard octagonal box for storing cooked disc-shaped food such as pizza delivered to the home.

[0002]

2. Description of the Related Art Conventionally, an octagonal box as shown in FIG. 6 has been used for delivery of pizza. In this box, a front plate 2, a rear plate 3 and a pair of side plates 4 are continuously connected to an octagonal bottom plate 1 using a corrugated board sheet as a material.
By extending the folding pieces 6 from both side edges of the front plate 2 and the rear plate 3, respectively, and connecting the corner plate 5 and the folding piece 6 with the connecting piece 7.
The lid plate 8 is continuously provided on the upper edge of the lid plate 8 from both side edges of the lid plate 8.
Are formed from blanks in which the front offset pieces 10 are respectively extended from the front edge.

When assembling this box from a blank and packaging pizza, the pizza is placed on the bottom plate 1 and the bottom plate 1
The front plate 2, the rear plate 3, and the both side plates 4 are erected from the above, and at the same time, the corner plate 5, the folding piece 6 and the connecting piece 7 are folded, and the lid plate 8
Is closed to close the top surface, and the side difference piece 9 and the front difference piece 10 are inserted into the box and sealed.

[0004]

However, in the octagonal box as described above, when a cooked food such as a home-delivered pizza is stored, high temperature moisture is likely to be trapped inside the bottom plate, and the moisture causes dew condensation. , Foods may absorb moisture and become sticky, or the bottom plate may soften, resulting in a decrease in box strength.

Further, when assembling the blank, since the bending is returned by the repulsion of the corrugated board, it is necessary to close the lid plate while manually pressing the front plate and the side plates, which causes a problem of poor workability.

Therefore, according to the present invention, an octagonal shape which is excellent in workability at the time of assembling as well as the quality of the food and the strength of the bottom plate can be maintained even if the cooked food such as pizza is stored in the bottom without keeping the moisture in the bottom. It is intended to provide a box.

[0007]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention relates to an octagonal box made of corrugated board, in which the corrugated corrugated steps are formed among the ridges of the bottom plate, front plate, rear plate and both side plates. At the ridge in the direction orthogonal to the eyes, a vent hole is formed so that the cross section of the bottom plate is exposed, and the moisture in the corrugated board of the bottom plate is discharged from this vent hole.

A state in which the end of the bottom plate is cut from at least one of the front plate, the rear plate and both side plates, and leg pieces projecting downward during assembly are provided and placed on a table or a plurality of boxes are stacked. However, there is a gap below the bottom plate so that moisture can be released effectively.

Further, a provisional fixing piece is provided on the upper end of the corner plate so as to contact the back surface of the folding piece when it is bent outward during assembly, so that the folding back due to the repulsion of the corrugated board is prevented.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, the blank of this box is
Using corrugated cardboard as a material, octagonal bottom plate 1 with front plate 2,
The rear plate 3 and the pair of side plates 4 are provided in series, and the corner plates 5 are extended from both side edges of each side plate 4 and the folding pieces 6 are extended from both side edges of the front plate 2 and the rear plate 3, respectively. 6 and 6 are connected by a connecting piece 7, a lid plate 8 is continuously provided on the upper edge of the rear plate 3, side offset pieces 9 are extended from both side edges of the lid edge 8, and a front offset piece 10 is extended from the front edge. Has become.

In this blank, corrugated corrugations are oriented in the front-rear direction, and ventilation holes 11 are formed by linear cuts in the ridges of the bottom plate 1 and the front plate 2 orthogonal to the corrugations.

Here, the cut of the vent hole 11 is made considerably longer than the cut of the lead ruled line that facilitates bending,
Further, it is not a punching process that penetrates through the front and back, but a half-cutting process that cuts only the front surface side.

A leg piece 12 is provided at the end of the bottom plate 1 by cutting from both ends of the side plate 4, and a fold is formed at the base end of the cut at the outer edge of the tip of the corner plate 5. A temporary stop piece 13 is provided.

When assembling such a blank and packaging pizza, the pizza is placed on the bottom plate 1 and the front plate 2, the rear plate 3 and the both side plates 4 are erected from the bottom plate 1 as shown in FIG. At the same time, the corner plate 5, the folding piece 6 and the connecting piece 7 are folded.

At this time, as shown in FIG.
When the sheet is bent outward, the temporary fixing piece 13 comes into contact with the back surface of the folding piece 6, and the return of the front plate 2, the rear plate 3 and the both side plates 4 to the lying state due to the repulsion of the corrugated board is prevented.

Therefore, even if the front plate 2 and both side plates 4 are not supported by hand, as shown in FIG. 3, the lid plate 8 is closed to close the top surface, and the side difference piece 9 and the front difference piece 10 are closed. Can be inserted into the box and sealed, improving workability during assembly.

When assembled in this way, the bottom plate 1 and the front plate 2 are formed by cutting the vent holes 11, as shown in FIG.
Since the cross section of the corrugated cardboard of the bottom plate 1 is exposed at the ridges of the pizza, the high temperature moisture that has penetrated into the corrugated cardboard of the bottom plate 1 from the back surface of the pizza is released from the ventilation holes 11, and the stickiness of the pizza dough and the softening of the bottom plate 1 are caused. The strength is prevented from being reduced.

As shown in FIGS. 2 and 3, the leg piece 1
Even when 2 is projected downward and placed on a table or a plurality of boxes are stacked, a gap is formed below the bottom plate 1, so that moisture is released more effectively.

By the way, the vent hole 1 formed by half-cutting
1 does not communicate with the inside of the box as shown in FIG.
As shown in FIG. 2 and FIG. 3, the extraction hole 2 is directed downward, so that dust does not enter the box, so that a sanitary problem does not occur.

The shape of the cut of the vent hole 11 is not limited to the straight line shape as shown in FIG. 1, but as shown in FIG. 5, both sides are bent and the middle portion slightly cuts in the direction of the front plate 2. It may be trapezoidal.

The vent holes 11 may be formed on the ridges of the bottom plate 1 and the rear plate 3 in addition to the ridges of the bottom plate 1 and the front plate 2.
In this case, the ridges of the bottom plate 1 and the rear plate 3 are subjected to the load and the twist of the cover plate 8, so it is better not to cut too long.

Further, when the corrugated corrugated sheets are oriented in the left-right direction, the vent holes 11 may be formed in the ridges of the bottom plate 1 and the side plates 4.

Besides, the leg pieces 12 may be formed not only at the both ends of the side plate 4 but also by cutting the bottom plate 1 from the center part, the front plate 2 and the rear plate 3.

[0025]

As described above, in the octagonal box according to the present invention, among the ridges of the bottom plate, the front plate, the rear plate and both side plates, the bottom plate is formed at the ridges in the direction orthogonal to the corrugated steps of the corrugated board. Since the vent hole whose cross section is exposed is formed, moisture in the corrugated board of the bottom plate is released from the vent hole, and stickiness of food due to dew condensation and reduction in strength of the bottom plate are prevented.

Further, since the end portion of the bottom plate is cut from at least one of the front plate, the rear plate and both side plates, and the leg pieces protruding downward are provided at the time of assembly, they are placed on a table or a plurality of boxes are stacked. Even in the open state, a gap is formed below the bottom plate, and the softening of the bottom plate is more effectively prevented.

Further, since a temporary fixing piece which comes into contact with the back surface of the folding piece when bent outward during assembly is provided above the tip of the corner plate, the folding back due to the repulsion of the corrugated board is prevented.
Workability during assembly is improved.
