Description

  The present invention relates to a folded box with a partition made of corrugated cardboard that is folded flat when stored and can be easily assembled when used.

For transporting a large number of small parts such as automobile parts, a cardboard box into which a partition having a plurality of compartments is inserted is used.
If this partitioned cardboard box is stored in the packaging work site in an assembled state, the packaging work can be performed efficiently, but a large storage space is required. Also, storing the partitions and boxes in a blank state and assembling them at the packaging site requires less storage space but takes time to assemble.
Thus, there is a need for a folding box in which the cardboard box and the partition are folded in a flat state at the time of storage and can be assembled with one touch at the time of use.

  Various types of folding boxes that meet the above requirements have been developed, but as practical, side wall pieces and front and rear wall pieces are arranged opposite to each other on the bottom, and the side wall pieces and front and rear walls are provided. There is a structure in which a folding piece that is continuously connected to the piece and is folded at 45 degrees is provided, and the front and rear wall sides of the folding piece are attached to the front and rear wall pieces (for example, see Patent Document 1). Moreover, as a partition which can be folded, there exists what folds flatly, making a horizontal partition engage with a vertical partition (refer patent document 2).

As shown in FIG. 7, the folding box 500 of Patent Document 1 has an open upper surface, and a single-wall side wall 2 </ b> A and a double-wall front and rear wall 3 </ b> A are erected on four sides of the bottom surface 1. Then, the folding piece 4 connected to the side wall 2A and the front and rear walls 3A is folded at 45 degrees and attached to the front and rear wall pieces 3, and the inner wall piece 5 connected to the front and rear wall pieces 3 is folded inward to form an adhesive tape. 11 is assembled by fixing.
When the folding box 500 is stored, the inner wall pieces 5 of the front and rear walls 3A are expanded, the side walls 2A are folded and stacked on the bottom surface 1, and are in a flat state.

The folding box 500 of Patent Document 1 has a simple structure and can be easily assembled, but has the following problems.
First, when the side wall 2A is higher than a certain height, when folded, the upper ends of the left and right side walls 2A are close to each other, and when assembling, the finger does not hang on the upper end of the side wall 2A, which takes time. Moreover, although the inner wall piece 5 is fixed with the adhesive tape 11, if it adheres beforehand, it will deteriorate easily at the time of storage, and if it adheres at the time of an assembly, assembly time will increase.
Further, the handle 3a is provided at the center upper portion of the front and rear wall 3A, but it is difficult to lift because it is formed only on the outer wall piece 3 of the front and rear wall 3A.

Although the partition of Patent Document 2 is not shown, a horizontal partition member and a vertical partition member made of bi-folded cardboard that open downward are arranged in a right angle direction, and fitting grooves formed respectively are fitted to each other. Is. In a state where the horizontal partition member and the vertical partition member are fitted, the structure is not easily detached, and can be folded flat.
Although this partition is sufficiently satisfactory, there is a problem that the cardboard is folded in half and used, which requires a lot of processing and increases the cost.

  An object of the present invention is to solve such problems of conventional products with a simple structure, and to provide a durable and economical folded folding box.

  In order to achieve the above object, the partitioned folding box of the present invention is configured as follows. That is, the folding box is formed by folding up a single cardboard and having an open top, and a plurality of rectangular partitions that are inserted into the folding box and partitioned into rectangular shapes. Consists of a single side wall and a double wall front and back wall, and a side wall piece and a front and back wall piece are arranged in opposition to the periphery of the rectangular bottom, and are provided at the end of both wall pieces at 45 degrees. Folded pieces that are folded and attached to the front and rear wall pieces are provided.When storing, the left and right side walls are folded inward and stacked flat on the bottom, and when used, the left and right side walls are interlocked by raising the left and right side walls. The front and rear walls are latched by folding inner wall pieces connected to the front and rear wall pieces inward, and locking pieces protruding from the inner wall pieces provided on the bottom surface. It is assembled by being fitted in a groove, and a notch portion for hooking a finger is provided at the center of the upper end of the side wall piece of the folding box.

This partitioned folding box is used to individually store a large number of parts and the like, and is folded flat when stored and easily assembled in a short time when used. Both boxes and partitions are made of cardboard.
The size of the box is not particularly limited, but it is desirable to have a weight that can be accommodated and lifted by one person. Moreover, when the left and right side walls are folded so as to overlap the bottom surface, it is desirable that the height of the side walls not be overlapped and be as close as possible.
The notch portion provided at the center of the upper end of the side wall piece is for easily raising the side wall, and the size and shape are not particularly limited as long as a finger is applied.

The folding piece is a square connected to the side wall piece and the front and rear wall pieces and is folded at 45 degrees from the four corners of the bottom surface, and the side connected to the front and rear wall pieces is attached to the front and rear wall pieces.
This folding piece may be folded only at 45 degrees, but as described in claim 2, a horizontal cut is provided in the direction perpendicular to the side wall from the middle of the 45-degree inclined fold, The upper side of the handle may be formed in a strip shape extending to the center. In addition, it is desirable that this strip shape is close to the center of the front and rear wall pieces.
On the other hand, as long as the partition inserted into the folding box can be folded flat in the assembled state, the shape / structure is not particularly limited, but a fitting groove is formed as described in claim 3. It is desirable that a plurality of horizontal partitions are combined in a cross shape with a belt-like vertical partition, and the horizontal partition is assembled so that it can be folded flat while being connected to the vertical partition. In addition, it is good to provide a latching means in a fitting groove so that it may not separate easily in the state combined in the shape of a cross.

In the folding folding box of the present invention, a single-wall side wall piece and a double-wall front and rear wall piece are connected by a folding piece, the folding piece has a 45-degree fold, and one side of the front and rear wall is attached to the front and rear pieces. The front and rear walls are formed by folding an inner wall piece connected to the front and rear wall pieces inward, and fitting a locking piece protruding from the inner wall piece into a locking groove provided on the bottom surface. Since the cut-out portion where the finger is hooked is provided at the center of the upper end of the side wall piece of the folding box, the side wall can be easily raised when the folding box is assembled. Moreover, since the front and rear walls do not use an adhesive tape as in the prior art, there is no inconvenience.
Further, as described in claim 2, the front and rear walls are provided with a handle cut out in an elliptical shape at the center, and the folding piece is provided with a horizontal cut in a direction perpendicular to the side wall from the middle of the 45-degree inclined fold. If the upper side of the handle of the front and rear wall pieces is formed and pasted in a strip shape extending to the center, the upper part of the handle becomes strong, and even if a heavy object is stored, it will not be damaged.
Further, as described in claim 3, the partition inserted into the folding box is combined with a strip-shaped cardboard vertical partition formed with a fitting groove, and a plurality of cardboard horizontal partitions are combined in a cross shape, and If the horizontal partition is assembled so that it can be folded flat while being connected to the vertical partition, it can be made inexpensive and durable.
