Description

[Detailed description of the invention] [Field of industrial application] This invention is designed to securely store and partition three spherical objects, such as large fruits such as watermelon and melon, and cylindrical objects, without any movement, in a packaging box. , relates to a partition made of cardboard or other cardboard that divides the interior into three rooms.

[Prior Art] Various types of partitions have been used in the past, depending on the box body and the size and shape of the stored items, but it is difficult to fit three spherical items into a square box, and the partitions are prone to wobbling and At present, it is difficult to obtain a product that is practically satisfactory due to deformation caused by shaking during transportation. This is a particular problem in the case of spherical fruits that are perishable, vary in size, and are relatively heavy. Also, these fruits are shipped in large quantities in a short period of time, and standardized packaging boxes are used for handling and other convenience. In conjunction with this, there was a need for a three-piece partition that could be used to easily and reliably hold the partitions.

From the above viewpoint, the present applicant has developed several three-room partitions [Utility Application No. 55-113680, etc.]
-37857 Publication].

[Problems to be solved by the invention] However, even with the three-room partition device of the above-mentioned application, there were problems such as requiring a lot of skill and making the assembly easier.

[Means for solving the problem] In view of the above-mentioned current situation, the inventor of the present invention has completed the present invention as a result of intensive research. It is an assembly consisting of two triangular top surfaces each of which is formed by mountain folds on each side and extends backwards in a somewhat slanted state with the short side as a common base, and a top surface that slopes forward from the tip of the short side. The mountain-folded sloped folds extended in a radial manner in plan view,
The partitioning surfaces are formed by bending and erecting surfaces extending from both sides of the above-mentioned inclined fold and each side of the top surface except for the short sides.

Here, the cardboard sheet refers to a thick paper or cardboard sheet.

The three-room partition of the present invention is composed of a top surface and a partition surface.

Here, the top surface is composed of two triangles, each side of which is formed by a mountain fold, and the two triangles share a short side.

The slanted fold is a mountain fold that extends from the tip of the short side in an inclined state. This inclined fold and the two top surfaces are provided radially in a plan view.

Partition surfaces refer to the folded and upright surfaces connected to both sides of the inclined fold and to each side of the top surface except for the short sides.

[Example] Hereinafter, the present invention will be described in detail based on an example shown in the drawings.

FIG. 1 shows an example of a partitioning device according to the present invention. This partition 1 is made of corrugated cardboard, and has two triangular top surfaces 2 and 3 and an inclined fold 4 that are radially connected at substantially equal angles when viewed from above, and each side 5 and 6 on both sides of the inclined fold 4. The six surfaces 8, 9, 10, and 11 that are bent and stand up and are connected to the sides 21, 22, 31, and 32 of the top surfaces 2 and 3 other than the common base 7 serve as partition surfaces.

The top surfaces 2 and 3 are elongated triangular shapes that extend diagonally backward with their short sides being a common base 7 in a somewhat inclined state. It extends forward and slopes forward. Note that the two top surfaces 2 and 3 and the inclined fold 4 form substantially equal angles when viewed from above means that when viewed from above, the inclined fold 4 is the side other than the short side that is connected to the starting point of the fold. The two angles 21 and 31 (the angles in Figure 2)
This means that ECA and angle FCA) are almost equal to the angle formed by the remaining sides 22 and 32 of the top surface other than the short side (angle EDF in Figure 2).

Each of the above partition surfaces are partition surfaces 5, 8, 9, 10, and 1.
1 and 6 are connected to each other to divide the box K into three chambers (Fig. 3), each partition surface is connected to another partition surface or the top surface on two sides, and partition surfaces 5 and 6, 8 and 9 ,10
and 11 are stacked back to back, so it exhibits strong resistance to bending and compression, and also has cushioning properties. In the figure, numerals 12, 13,
Reference numerals 14 indicate boundaries between the partition surfaces 5, 8, 9, 10, 11, and 6, respectively.

To form and assemble this partition 1 from one sheet, for example, the following procedure is performed. That is, as shown in FIG. 2, in the center of one diagonal line AB of the substantially rectangular corrugated paperboard sheet 1', a portion CD (mountain crease) that will become the base 7 is defined, and from each point C and D on the opposite side Sides 21 and 2 of the top surfaces 2 and 3 are placed at points E and F, respectively.
The lines CE, DE, CF, and DF, which correspond to lines 2, 31, and 32, are provided as mountain creases, and the line segment CA is formed as a mountain crease to form the above-mentioned inclined fold 4. Further, from point C to points G and H on the other opposite sides, valley fold lines CG are formed to become the boundary lines 12 and 14,
A CH is provided and the DB is made into a valley-folded line so that the boundary line 13 is also the same. In addition, the notches 15 at points A and B,
Reference numeral 16 is for making the tips of the partition surfaces 5 and 6 and the bottom surfaces of the partition surfaces 9 and 10 flat when assembled.

Therefore, to assemble the partition 1 from the sheet 1', first hold the sheet 1' in both hands and
Fold the whole thing into a mountain along AB, then each border line 1
By valley-folding 2, 13, and 14, the whole can be easily narrowed and bent according to each crease, and a partition tool having a shape as shown in FIG. 1 can be obtained.

As shown in FIG. 3, the assembled partition 1 is inserted into the center of a packaging box K that is square in plan view and contains three items S, and the lid is closed and sealed to complete the packaging ( (The top flap of the box body is omitted in the figure).
Note that the pressure from above is received by the top surfaces 2, 3 and the bottom 7, and this is received by the bottom of each partition surface, but since each partition surface is bent by the boundary lines 12, 13, and 14, the pressure is large. It can withstand enough. However, in a case formed from a rectangular sheet as shown in the figure, the bottom surfaces of all partition surfaces are not flush due to its shape.

In addition, each partition surface 5, 8 of the partition tool in the box body K,
9, 10, 11, and 6 are pushed by the spherical stored objects S and try to move inward, but as mentioned above, they are connected to other partition surfaces and the top surface, so they cannot move independently. Unable to do so, it deforms to fit the spherical contents. Therefore, each stored item S comes into contact with each partition surface at a plane rather than a point, and the force applied to the top surface can be applied diagonally from above, resulting in good stability and excellent cushioning properties. be. Furthermore, since the partition 1 contacts the stored item S so as to pinch it from two sides, it does not rotate, move up and down, or move during transportation. In this example, since the two triangular top surfaces 2 and 3 and the inclined folds 4 are radially connected at substantially equal angles in plan view, the box K can be divided into three sections of approximately equal size. It can be divided into equal parts, but if you change the angle, you will get 3 pieces of different sizes.
It can be used to store individual spherical items.

Next, FIG. 4 shows another example of the partitioning device of the present invention, in which the mountain-folded portions 21 forming the top surfaces 2 and 3 excluding the bottom side 7,
22, 31, and 32 are formed with concave curves. By doing this, bending during assembly can be done more easily, and stronger pressure resistance can be obtained since there are no bends at points C and D, and the upper parts of the partition surfaces 5 and 6 are also spaced apart by a few minutes. The cushioning properties of the part are increased. Furthermore, as shown in FIG. 5, if the bottom side 7 and the inclined folds 4 are made wider, the cushioning properties will be further improved.

[Effects of the invention] As explained above, the partition according to the invention has the following effects:
It is made by dividing a rectangular or other cardboard sheet into two elongated triangular top surfaces and slanted folds, and using each continuous surface as a partition surface, narrowing and folding the sheet with creases. , the area of the top surface and inclined folds is smaller than that of conventional products, so it is easy to assemble and is reliable, and has excellent cushioning properties for the top surface and inclined folds, and is pressure resistant and resistant. It has good twistability and shape retention, and the partition surface conforms to the spherical contents, so when used to partition large spherical fruits such as watermelons and melons, they can be moved and rotated effectively within the packaging box. It has extremely high practical value, such as excellent protection and cushioning properties.
