BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has two vertical rows and a plurality of horizontal rows by simply bending one sheet-shaped material having folds or cuts at predetermined positions along the folds. The present invention relates to a foldable strawberry pack tray that has a box-shaped tray integrally provided with a partition that forms a partition section and can be used as a returnable box.

[0002]

2. Description of the Related Art The applicant of the present application has previously described a packing tray for packed strawberries, "Japanese Patent Application No. 3-299947",
"Japanese Patent Application No. 3-359200" and Japanese Patent Application No. 7-265
No. 522 ”has been filed. In each of the above-mentioned prior inventions, since only one sheet-shaped material (corrugated board) is bent along the fold line, the tray integrally provided with the cross-shaped partition is folded up at once. Like the conventional technology,
It has the excellent feature that the tray and the partitioning material are made separately, and the complicated work of combining them is omitted, and the conspicuous reduction of the packaging cost is achieved.

In addition, when the trays are stacked in a plurality of stages and then banded together into one package, the trays of the respective stages are prevented from laterally shifting to each other during transportation, so that the four corners of the upper edges of the trays are prevented. The engaging piece provided on the tray is engaged with the engaging hole provided on the bottom surface of the tray. Furthermore, 2 of the partition
A perforation for division is also provided so that the 4-pack containing tray can be divided into two pack containing trays, if necessary, by utilizing the stacked structure.

Alternatively, when the packing bands are strongly hung on the stacked trays, the upper tray is deformed, and the bottom of the tray is prevented from slipping down inside the lower tray and damaging the strawberries. In order to make it possible to smoothly perform the fitting operation at the time of folding, the morphology is devised. Furthermore,
Ventilation holes are provided in the partition wall so that cold air can easily get inside the tray during refrigeration to maintain freshness.

[0005]

However, there is still room for improvement in the above-mentioned prior inventions. The first is that you can pack only four strawberry packs,
The work efficiency in handling is poor. In No. 2, when the tray was folded up by the fitting method, both ends of the front and rear side walls protruded out of the side wall of the tray, and the protruding portions interfered with the band hanging.
In No. 3, both ends of the tray bottom also protruded to the outside of the side wall, so the volume increased correspondingly, and storage and transportation
It was uneconomical. Therefore, an object of the present invention is to provide a folding type strawberry pack tray that solves the above problems of the prior invention.

[0006]

In order to achieve the above-mentioned object, the strawberry pack tray according to the present invention can be formed by folding a substantially rectangular sheet-like material 100 along a fold line and A box-shaped tray 200 integrally provided with an intermediate partition in a form in which a plurality of horizontal partitions are meshed with each other at right angles to a vertical partition of a row is formed.

It is connected via. The left and right side walls 2 and 3 are provided with a two-fold fold B for reinforcing the side walls by bending the two side walls into a stacked shape and for convenience of printing described later.

At the respective side ends of the left and right side walls 2 and 3, half-side bottom surfaces 4 and 5 which are half of the bottom surface of the tray 200 are formed.
Are connected to each other via a fold line C. Further, vertical partitions 6 and 7 are connected to the respective side ends of the half-side bottom surfaces 4 and 5 via folds D, respectively. Both vertical partitions 6, 7 are
When the tray 200 is folded up, two trays are stacked as shown in FIG. The lateral width dimension (the vertical length in FIG. 1) between the folds B and D is set to be slightly shorter than the lateral width of the other portion of the sheet material 100.

Further, at positions near the front and rear ends of the central surface 1, the front and rear side walls 8 and 9 of the tray 200 are formed with raised and cut folds and cut and cut folds described below, respectively, for raising the front and rear side walls 8 and 9 in a raised shape. It is provided so as to straddle between both main folds A and A.

That is, a crease E for cutting and raising for forming the front side wall 8 upright is provided at a position separated from the front edge a of the central surface 1 by a predetermined distance. In addition, the overlapping piece 1 for overlapping with the front side wall 8
The cut-and-raising cuts 11 for forming 0 are provided in parallel with each other on the inner side at a predetermined distance from the cut-and-raised folds E. On the other hand, at a position separated from the rear edge b of the central surface 1 by a predetermined distance, a cut-and-raised fold E for standingly forming the rear side wall 9 and a cut-and-raised cut 11 are provided in parallel at predetermined intervals.

Further, between the front and rear side walls 8 and 9, in order to form four horizontal partitions 12 upright in parallel at predetermined intervals, eight cut-and-raising cuts 11 are provided at predetermined intervals. Are installed in parallel. Then, these four horizontal partitions 12 are provided with U-shaped ventilation notches 13 at two locations on the upper edge of each of them.

On the left and right side walls 2 and 3, there are provided trapezoidal auxiliary pieces 14 for standing up, which play a role of raising the front and rear side walls 8 and 9 and the lateral partitions 12, respectively.
It is provided at both ends of each of the two in a state of being continuous with each other through the main fold line A. As shown in FIG. 1, the auxiliary pieces 14 for standing up are formed by cutting the folds E for cutting and the cutting cuts 11 for every other one of the eight lines into adjacent cutting and cutting cuts 11 from both ends. It is formed so as to be surrounded by an oblique fold F having a predetermined length that extends toward the angle of 45 degrees, and an L-shaped cut 15 that extends from the tip of the oblique fold F toward the end of the adjacent cut-and-raise cut 11. .

Half-cut lines are provided on the back sides of the cut and raised fold E and the oblique fold F, respectively, so that these folds can be bent more smoothly. Further, slit-shaped holes c are provided at both ends of the cut and raised fold E.

At both ends of the cut-and-raised cut 11, which is the upper edge of the front and rear side walls 8 and 9, locking pieces 16 are provided in a symmetrical manner so as to straddle both sides of the main fold A. This locking piece 16
When the tray 200 is folded up, as shown in FIG. 4, the trays are projected to the four corners of the upper edge thereof.

On the other hand, the bottom surfaces 4 and 5 on one half side and the left and right side walls 2 and 3
Engagement holes 17 for engaging the locking pieces 16 are provided at both ends of the fold line C, which is a boundary line between the two lines, in a notched shape across both sides of the fold line C. Then, the hollow holes c provided at both ends of the cut and raised fold line E also constitute a part of the engagement hole 17. Further, notches d are provided at both ends of the fold line B to avoid interference with the locking pieces 16.

Further, as shown in FIGS. 2 to 4, in the process of folding the cardboard 100 into the tray 200, the left and right side walls 2 and 3, both half side bottom surfaces 4 and 5, and vertical partitions 6 and 7 are formed. Fitting cuts 18 to 20 are provided at the positions where the front and rear side walls 8 and 9 and the horizontal partitions 12 interfere with each other in the arrangement shown in FIG.

At the intersection of the fitting cut 18 and the fold C, a substantially spindle-shaped notch hole 21 is provided. The notch hole 21 allows the fitting operation when the tray 200 is folded up to be performed more smoothly, and also serves as a ventilation hole.

Next, the operation of the above configuration will be described. In order to fold up the tray 200 from the cardboard 100, first, the left and right sides of the central surface 1 are held with both hands, and the main folds A, A are once bent downward to give a downward folding habit.

Next, as shown in FIG. 2, both main folds A, A are bent upward and the left and right side walls 2, 3 are raised to face each other. As 12 is pressed between the left and right side walls 2 and 3, the main fold A is bent downward and the oblique fold F is bent upward.
Therefore, the front and rear side walls 8 and 9 and each lateral partition 12 are naturally erected.

Therefore, as shown in FIGS. 2 and 3, the left and right side walls 2 and 3 are folded inward along the folding fold B for folding into two sheets. Then, when the creases C and D are bent downward at right angles, the front and rear side walls 8 and 9 and the lateral partitions 12 which are erected, the left and right side walls 2 and 3, both half side walls 4,
5 and the vertical partitions 6 and 7 allow the fitting cuts 18 to 20 provided at the respective positions where they interfere with each other to be meshed with each other, and as shown in FIG. The tray 200 including the total 10 partition sections S is folded up without any trouble, and the folded shape is reliably fixed.

At the time of this meshing, as can be understood from FIG. 3, since a relatively large notch hole 21 is provided at the intersection of the fitting cut 18 and the fold C, the meshing operation is performed. It can be done smoothly and without any problems.

As shown in FIGS. 4 and 5, the folded tray 200 has locking pieces 16 projecting from the four corners of its upper edge.
Further, at the four corners of the bottom surface, engaging holes 1 for engaging the locking pieces 16 are provided.
7 is formed. Therefore, the tray 200
It is possible to surely eliminate the risk that the trays 200 in each stage will move relative to each other when they are stacked in multiple stages for the convenience of transportation and handling.

Further, in order to maintain the freshness of the strawberries, when the tray 200 containing the packed strawberries is stored in a large refrigerator and cooled, the ventilation notch 13 provided at the upper edge of each horizontal partition 12 is used.
However, it serves to quickly spread the cool air into the respective partition sections S of the multi-tiered trays. In this case,
The engagement hole 17 and the notch hole 21 which are largely opened also contribute to the rapid diffusion of the cool air.

6 and 7 show a second embodiment. The difference from the first embodiment is that the folded tray does not become unnecessarily bulky, and that the tray that is stacked in multiple stages has a protruding portion that interferes with the outer peripheral surface of the tray so that a packing band can be easily attached. It is in the place where I lost it.

For that purpose, the corrugated board 101 shown in FIG. 6 is used.
Is used as a material for folding up the tray 201 shown as a partial perspective view in FIG. The corrugated board 101 is provided with fixing means for fixing the protruding portions 6a, 7a at both ends of the vertical partitions 6, 7 to the outer side surfaces of the front and rear side walls 8, 9 in a folded state as shown in FIG. Is provided.

The fixing means in this case is a small rectangular opening 22 provided at the lower center of each of the front and rear side walls 8 and 9. The bent states of the protrusions 6a and 7a are fixed by inserting the lower ends of the protrusions 6a and 7a into the hollows 22. The fixing means is not limited to the illustrated structure, and various known fixing methods may be used.

In the corrugated board 100 of the first embodiment, the fin-like portion e between the trailing edge b and the cut-and-raised fold E adjacent to the trailing edge b.
So that a part of the bottom of the folded tray 200 does not project laterally.

The use of the strawberry pack tray is not limited to the strawberry pack use, and it goes without saying that the size of each part may be appropriately changed and used for another purpose. And the trays 200, 20
The number and arrangement of the partition sections S provided in 1 are not limited to those shown in the figure,
For example, it is possible to provide partition sections of 3 rows or 4 columns and 15 rows. In that case, widen one or both of the widths of the bottom surfaces 4 and 5 on one half side, and add an intermediate vertical partition to this part.
It may be formed in a folded shape.

Further, this tray which can be folded and assembled freely and can accommodate a larger number of strawberry packs can be conveniently used as a carrying box. In that case, as the material of the sheet material 100, a plastic corrugated board or a plastic plate excellent in water resistance and durability may be selected.
