Since the substantially rectangular corrugated cardboard 100 is provided with folds, cuts, and the like at a plurality of predetermined locations, the manner of providing them will be described in detail below. Cardboard 100
The left and right side walls 2 and 3 serving as the left and right side walls of the tray 200 are respectively provided on the left and right sides thereof with a main fold A
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.

[0007] At the side edges of the left and right side walls 2 and 3, respectively, half-side bottom surfaces 4 and 5 which form half of the bottom surface of the tray 200, respectively.
Are connected to each other via a fold line C. Further, longitudinal partitions 6 and 7 constituting a cross-shaped middle partition are continuously provided at respective side ends of the respective half-side bottom surfaces 4 and 5 through folds D, respectively. When the tray 200 is folded up, the two vertical partitions 6 and 7 are in a two-layered state as shown in FIG.

[0008] The width W of the bottom surfaces 4 and 5 (see FIG. 1)
As shown in FIGS. 5 and 6, when the tray 200 is folded up, the bottom width m is set to a size that is not narrower than the top width n of the tray. As shown in FIG. 1, the width of the corrugated cardboard 100 is such that the portion between the two-fold fold B and the fold D is slightly smaller than the other portions.

Further, on the central surface 1, front and rear side walls 8 and 9 which are front and rear side walls of the tray 200, and horizontal partitions 10 and 11 for forming two cross-shaped partition walls in a stacked state are respectively cut and raised. In order to form a standing shape, a plurality of cut-and-raised cuts 12 and cut-and-raised folds E are provided in a parallel manner so as to straddle both main folds A and A with the arrangement shown. However, in this embodiment, the cut-and-raised fold E provided in the middle of the center plane 1 is provided.
Is actually a break, not a fold,
It is easy to raise 0,11.

Each of the horizontal partitions 10 and 11 and the vertical partitions 6 and 7 is provided with a notch 30 having a substantially U-shaped ventilation cut at each of two locations on the upper edge side. It should be noted that perforations K reaching the left and right ends of the corrugated cardboard 100 are provided on both left and right sides of the middle cut-and-raise fold (cut) E, so that the tray 200 can be divided into two.

The right and left side walls 2 and 3 have front and rear side walls 8 and 9 respectively.
Also, the trapezoidal standing up auxiliary pieces 13 for assisting the standing up of the lateral partitions 10 and 11 are provided on the side walls 8 and 9 and the partitions 10 and 11, respectively.
Are provided in a state of being connected to both side ends of. This standing auxiliary piece 1
Reference numeral 3 denotes an oblique fold F having a predetermined length extending from both ends of the cut-and-raised fold E at an angle of 45 degrees with respect to the main fold A, and L extending from both ends of the cut-and-raised cut 12 adjacent to the cut-and-raised fold E, respectively. It is formed so as to be surrounded by the cut 14. A cut f is provided in the oblique fold F, leaving both ends thereof, so that the erection auxiliary piece 13 can be erected more smoothly.

At both ends of the cut-and-raise cut 12 which is the upper edge a of each of the front and rear side walls 8 and 9, locking pieces 15 are provided to protrude from four corners of the upper edge of the folded tray 200. The locking pieces 15 are provided symmetrically on the left and right sides of the main fold A so as to straddle the main fold A. Also, at both ends of each of the cut-and-raised folds E for raising the front and rear side walls 8 and 9, there are provided hollows 16 for helping the front and rear side walls 8 and 9 and the vertical support pieces 13 to rise.

On the other hand, at both front and rear ends of the fold C, there are provided L-shaped notches b into which the locking pieces 15 are inserted.
When the tray 200 is folded up, the notch b forms an engaging hole 21 into which the locking piece 15 is inserted, as shown in FIG.

Further, as shown in FIGS. 2 to 4, the corrugated cardboard 100 is folded up into the tray 200, and the left and right side walls 2, 3 and both bottom surfaces 4, 5 and the vertical partitions 6, 7 are formed. At the locations where the front and rear side walls 8, 9 and the horizontal partitions 10, 11 interfere with each other, cuts 17 to 20 for fitting are provided in the arrangement shown in FIG.

Of these fitting breaks, the fitting break 17 has a spindle-shaped or centered width around the intersection so that the fitting operation can be smoothly performed at the intersection with the fold C. Is provided with an expanded portion 17a expanded in a diamond shape.

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, the main folds A, A are bent upward and the left and right side walls 2, 3 are erected to face each other. 10,1
Since the main fold A is bent downward and the oblique fold F is bent upward as 1 is pressed between the left and right side walls 2 and 3, the front and rear side walls 8, 9 and the horizontal partitions 10, 11 are bent. , Respectively, are naturally raised along the cut-and-raised folds E.

Thereafter, as shown in FIGS. 2 and 3, the left and right side walls 2 and 3 are folded outward along the folding fold B in a double-layered manner. In this state, the cardboard may be turned upside down. Subsequently, when the folds C and D are bent downward at right angles, respectively, the front and rear side walls 8 and 9 and the horizontal partitions 10 and 11, the left and right side walls 2 and 3, the bottom surfaces 4 and 4 on both sides are formed.
5 and the vertical partitions 6 and 7 are engaged with each other at fitting breaks 17 to 20 provided at positions where they interfere with each other. As shown in FIG. 4, a tray integrally provided with a cross-shaped intermediate partition is provided. 200 folds up without hindrance, and this fold-up shape is securely fixed.

At the time of this engagement, as can be understood from FIG. 3, the width of the fitting cut 17 is expanded at the intersection with the fold C by expanding the width into a spindle shape or a rhombus shape. Since the portion 17a is provided, the operation of fitting the horizontal partitions 10, 11 that are incompletely overlapped and are difficult to fit into the fitting cut 17 can be performed extremely smoothly.

As shown in FIG. 4 and FIG. 5, the latching pieces 15 project from the four corners of the upper edge of the folded tray 200.
At the four corners of the bottom surface, the engagement holes 21 into which the locking pieces 15 are inserted are provided. Therefore, when a plurality of trays 200 are stacked in multiple stages for transportation and handling,
There is no longer any risk that 00's will shift from one another.

Further, when the tray 200 is folded up, the bottom surface width m between both side ends of the half-side bottom surfaces 4 and 5 is equal to (or somewhat wider) the top surface width n of the tray. The width W of the half-side bottom surfaces 4 and 5 is set. Therefore, even if a packing band (not shown) is strongly hung on the stacked trays 200, as in the conventional case, the tray 200 slips down onto the bottom surface of the upper tray or the inside of the lower tray and reliably eliminates the risk of damaging the strawberries. (See FIG. 6).

The vertical partitions 6, 7 and the horizontal partitions 10, 11 constituting the cross-shaped middle partition are provided with ventilation notches 30 at two locations on the upper edge side, respectively. Therefore, in order to keep the freshness of the strawberry, when storing the tray containing the packed strawberry in a large refrigerator and cooling it, unlike the conventional tray, the cold air is quickly blown into each of the multi-stacked trays Can be efficiently distributed. In this case, the enlarged portion 17a of the fitting cut 17 or the engagement hole 2 for preventing the tray from slipping.
1 also aids in the rapid diffusion of cool air into each tray 200.

Alternatively, while the tray 200 is being folded, the left and right side walls 2 and 3 are folded in two layers, respectively, so that the structural strength of the tray 200 is greatly increased. or,
With the two sheets stacked, the entire outer peripheral surface of the side wall of the folded tray 200 can be made a printing surface only by printing on one side of the cardboard 100. Left and right side walls 2,
If 3 is a single wall, such economic effects cannot be obtained.

In the above configuration, the object of the present invention can be achieved even if the detailed configuration is appropriately changed in design. For example,
Of course, the shape of the notch 30 for ventilation, the place to be provided and the number of places are
The present invention is not limited to the illustration, and may be changed as appropriate according to the type of items stored in the tray 200.

[0025]

As apparent from the above description, the strawberry pack tray according to the present invention has various practically excellent effects as listed below. (A) By simply bending one piece of corrugated cardboard along a fold, a box-shaped tray integrally provided with a partition can be easily and quickly folded. (B) A notch for ventilation is provided on the upper edge side of each of the vertical partition and the horizontal partition, so that the trays containing strawberries etc. are cooled in multiple stages in a refrigerator to maintain freshness and cooled. Efficiency can be greatly increased. (C) In addition, when the tray is folded up, the width of the bottom surface between both side edges of the two half-side bottom surfaces is made equal to the width of the top surface of the tray. However, there is no problem that the bottom surface of the upper tray is shifted into the lower tray. (D) By expanding the width of the fitting cut into a spindle shape or a rhombus at the intersection with the fold, the fitting operation of each part when the tray is folded can be performed more easily and quickly. Looks like The widening also serves as a cooling vent.
