Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition plate for supporting relatively large fruits such as watermelon and the like which are housed in a cardboard box or the like.

[0002]

2. Description of the Related Art Conventionally, a rectangular corrugated cardboard sheet has an isosceles triangle top parallel to a short side in the center thereof, and outwardly facing fruit receiving pieces are bent and formed at both ends of the bottom side. A device has been developed in which it is inserted into a box and has an isosceles triangular partition plate and fruit receiving pieces provided on both sides thereof.

However, both side plates of the above-mentioned isosceles triangular partition plate are provided with bottom space holding pieces, and since the top forming angle cannot be made zero, both side plates of the partition plate cannot be in surface contact with each other, and the partition plate. It is difficult to make the storage volume on both sides variable and it is difficult to adapt to the size of the fruit, and it is difficult to fix the large and small fruits by the elasticity of the tops of both side plates.

Further, the partition plate and the fruit receiving piece have a problem that the surface is hard and lacks flexibility, and the fruit surface is easily damaged.

[0005]

DISCLOSURE OF THE INVENTION According to the present invention, the lower end of a partition plate bent downward from a top fold line is further bent to both sides, and a top fold angle α is set from zero to provide flexibility. By pressing the both side plates of the partition plate in accordance with the size of the fruit, the fruit receiving piece can flexibly receive the housed fruit and the surface of the both side plates of the partition plate can also flexibly receive the fruit and damage it. An object of the present invention is to obtain a tough and flexible partition plate that is not likely to be attached and can be easily set in a cardboard box before storing fruits.

[0006]

In order to achieve the above object, the present invention has a rectangular corrugated sheet having a bending line for forming a top portion in parallel with a short side in a central portion thereof, and a top forming angle can be opened from zero. It has elasticity and has both side folding lines parallel to the short side on both side plates of the folding line, and a fruit receiving piece is formed by connecting fruit receiving pieces to the outside of the both sides folding line. Box partitioning board The corrugated cardboard sheet is a double corrugated cardboard sheet, the paper thickness of the lower liner and the lower core is larger than that of the upper liner and the upper core, and the corrugated pitch and wave height of the upper core are The partition plate of the fruit storage box according to the above invention, which is larger than the corrugated pitch and the wave height of the lower core, and the central liner between the upper and lower cores is larger than the paper thickness of the upper liner and the upper core. It is constituted by the partition plate of the fruit storage box described in the second invention.

[0007]

According to the present invention, a rectangular corrugated cardboard sheet is bent downward on both sides from a top forming fold line formed in the central portion to form the top along the fold line. Open the opening angle from 0 (polymerization state) to the state where elasticity is added arbitrarily, and further bend horizontally from the folding lines on both sides to form fruit receiving pieces, which are placed in a cardboard box. Accommodate.

In this state, when fruits are stored on both sides of the partition plate, in the case of a small size, the fruits are in contact with the wall plate and the partition plate of the cardboard box with the top angle opened and are stored on the fruit receiving piece. It is fixed (Fig. 1).

Further, in the case of a large size, the angle of the top is small, and the top is sharply contacted between the wall plate and the partition plate of the corrugated cardboard box and supported and fixed on the receiving piece (FIG. 2). .
Large fruits can be housed and secured on both sides of the divider until both top plates meet each other.

The lower surface and one side surface of the above-mentioned stored fruit are in contact with the upper surface liner of the corrugated cardboard sheet, and a cushion is provided by the upper center core to protect the surface.

[0011]

[Example] A short side (width direction) at the center of a single-layer or double corrugated cardboard sheet 1 having a rectangular shape (length 85 cm, width 22.5 cm)
The bending line 2 for forming the apex is squeezed in parallel with, and the apex forming angle α is zero, that is, the angle α is opened from the state where the both side plates 3 and 3 of the bending line 2 are in double contact with each other, and the flexibility is arbitrary. Is attached.

With respect to the elasticity, a paper whose thickness of the lower surface liner 6 is thicker than that of the upper surface liner 8 is used, and its resilience and the core 7,
It is given by the compression repulsion force of 9.

Bend lines 4 and 4 parallel to the fold line 2 are formed at the lower ends of both side plates 3 and 3 of the fold line 2 in the center, and fruits are placed outside the fold lines 4 and 4 on both sides. The type receiving pieces 5 and 5 are continuously arranged in the horizontal direction.

In the double corrugated cardboard sheet, as shown in FIG. 4, the paper thickness of the lower surface liner 6, the lower central core 7 on the upper surface thereof, and the central liner 10 on the upper surface thereof is larger than that of the upper surface liner 8 and the upper central core 9. Thus, the waveform pitch P and the wave height H of the upper center core 9 are formed to be larger than the waveform pitch p and the wave height h of the lower center core 7.

The paper quality of the central liner 10, the lower surface liner 6 and the lower core 7 is not a high quality paper like the conventional paper quality of the core of a corrugated cardboard sheet, but the surface of the paper is rough and hard and rough. Can be used.

Although soft thin kraft paper is used for the upper surface liner 8 and the upper center core 9, other qualities of paper having good pullability may be used.

Reference numeral 14 in the drawing denotes a cover plate of the cardboard box 11, and 15 denotes a bottom plate.

[0018]

As described above, according to the present invention, when accommodating two relatively large fruits such as watermelon in an empty cardboard box, first, the folding line at the center of the cardboard sheet is folded into an acute angle. Bend, and then bend outward on both sides of the folding line to store the fruit receiving pieces on the bottom of the cardboard box, and in that state relatively large fruits 2 on each side of the partition plate 2 pieces easily Can be housed in

During storage, the corner forming angle α of the partition plate changes according to the size of the fruit, and both side plates at the top press the side surfaces of the stored fruit against both end wall sides of the cardboard box by elasticity. , You can stop the rattling of fruits.

Further, according to the present invention, as described above, since the contact surfaces of the partition plate and the fruit receiving piece made of the corrugated cardboard sheet are flexible, a cushion is provided for accommodating and supporting a comparatively large fruit, so that the inside of the corrugated cardboard box can be smoothly accommodated. Can be housed in

Further, in the present invention, since the central liner is thicker than the paper thickness of the upper liner and the upper core, not only the cushioning property of the upper liner and the upper core can be exhibited reasonably and uniformly, but also the lower corrugated board is robust. Because of this, it is rich in toughness and cushioning properties, and has the effect of being able to sufficiently support relatively heavy fruits such as watermelon.
