[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 19 are views showing one embodiment of a packing holding member according to the present invention. As shown in FIG. 1, a pair of packing holding members 11 are provided on the bottom side and the top side of the packing box 10. It is designed to protect from. Also, a pair of packing holding members 11
Are arranged so that their directions with respect to the package 13 are orthogonal to each other, so that the movement of the package 13 in the direction orthogonal to each other can be regulated. The packing holding member 11 is shown in detail in FIG. 2, and the packing holding member 11 as shown in FIG. 2 is made of a single corrugated cardboard material having a development view as shown in FIG. It is formed by bending. In FIG. 3, a hatched portion indicates a portion with a hole, and a portion indicated by a vertical parallel line in the lower left portion in the drawing indicates a direction of a flute of a corrugated cardboard material.

[0010] That is, in FIGS. 2 and 3, reference numeral 20 denotes a first horizontal plane having the largest area and arranged in parallel with the bottom surface and the top surface of the packing box 10. Reference numeral 21 denotes a first vertical surface which is continuous with the first horizontal surface 20, is bent from the bending line A, and comes into contact with the vertical surface of the packing box 10. Code 22
Is a second horizontal plane which is continuous with the first vertical plane 21, is bent from the bending line B, and is arranged in parallel with the first horizontal plane 20. Reference numeral 23 denotes a second vertical surface which is continuous with the second horizontal surface 22, is bent from the bending line C, and is arranged in parallel with the first vertical surface 21. Reference numerals 24 to 26 are continuous with the second horizontal plane 22 and are bent from bending lines D to F to form the first
This is a third vertical plane arranged in parallel with the vertical plane 21. Reference numerals 31 to 33 denote second vertical surfaces 23 and third vertical surfaces 24 to 24.
26, bending lines H to J and bending lines K to
A third horizontal plane bent from M and arranged in parallel with the first horizontal plane 20.

Reference numerals 35 and 36 denote third horizontal planes 31 and 33, respectively.
And a fourth vertical surface bent from the bending lines N and O and arranged perpendicular to both the third horizontal surfaces 31 and 33 and the first vertical surface 21. The wider end of each of the fourth vertical surfaces 35 and 36 is connected to a slit 39 of a fourth horizontal surface 39 described later.
a. Reference numeral 39 denotes the second vertical surface 23
To the first horizontal surface 20 which is bent from the bending line G.
Is a fourth horizontal plane arranged in contact with. Reference numeral 40 is
A fifth vertical surface that is continuous with the fourth horizontal surface 39, is bent in two directions from the bending lines P to R, and is disposed in parallel with the fourth vertical surfaces 35 and 36. The tip of the fifth vertical surface 40 is
The slit 32a of the horizontal surface 32 is fitted and held.

Reference numeral 42 designates a rising portion which is continuous with the first horizontal plane 20 and is arranged so as to be bent from the bending line S and rise, between the two bending lines S when rising. An engaging hole 42a having a width dimension enough to pass one corrugated cardboard is formed. The fourth horizontal plane 39 extends through the bending line G to the second vertical plane 2
3, the center of the fourth horizontal surface 39 on the bending line G side has an engagement hole 3 having a width dimension such that one cardboard passes therethrough.
9b is formed, and a rising portion 42 is inserted into the engagement hole 39b as shown in FIG. Reference numeral 44 is continuous with the third horizontal surface 32, is bent from the bending lines T and U, and has a front end portion as shown in FIG.
This is a locking portion that is inserted into and locked by a. By the way, several breaks V are made in the bending lines A, B, E, and P to facilitate bending.

The cut V is formed in an H shape.
That is, normally, when a corrugated cardboard is bent, a perforated cut is made.
As shown by the symbol Z in the figure, when the sheet is bent, a break occurs at the end of the cut, and this causes a problem in strength in a packing holding member assembled by folding such an article. Therefore, an H-shaped cut is employed as described above. As shown in FIG. 12, the length of the H-shaped cut in the direction of the fold is l, the length of the cut in the direction perpendicular to the direction of the fold of the cut is t, and the thickness of the cardboard material is T. When the relationship of T ≦ t / 2 (1) is established with respect to t, the occurrence of the above-described blur can be prevented. (1) between T and t
It is understood that as long as the relation of the formula holds, it does not matter whether l is long or short, and that it is not related to the flute. Therefore, when the relationship of the above equation (1) does not hold between T and t, a break occurs from the end of the cut as shown in FIG.

In the packing holding member 11, since the package 13 is placed on the third horizontal planes 31 to 33, the weight of the package 13 mainly depends on the third horizontal planes 31 to 33.
3 and is supported by the lower part of the second vertical surface 23 continuous with the third vertical surface 23. This is because the flutes of the corrugated cardboard material run in the vertical direction in the second vertical surface 23 as shown by being cut away in the portion a in FIG. Also the third
On the horizontal surfaces 31 to 33, not only the weight of the packaged goods 13 but also the weight (packing pressure) of other packing boxes and luggage loaded on the packing box 10 must be able to withstand. As shown in FIGS. 8 and 9, the fourth vertical surfaces 35 and 36 are provided perpendicularly to the third horizontal surfaces 31 and 33. However, the fourth vertical surfaces 35 and 36 are, as shown broken in part b of FIG. 8, because the flutes of the corrugated cardboard are running in the horizontal direction, they cannot withstand the vertical force alone. Absent. Therefore, as shown in FIG. 10, a fifth vertical surface 40 is provided which is arranged vertically from below the third horizontal surface 32. As shown in FIG. Because the eyes run vertically, they exert a relatively strong force against vertical forces.

As shown in FIG. 10, the tip of the fifth vertical surface 40 is fitted in a slit 32a of the third horizontal surface 32 and is kept vertical. In the figure, a step portion 40a is provided below the third horizontal surface 32.
Is formed, and the force applied to the third horizontal surface 32 is primarily supported by the step portion 40a. A pair of fifth vertical surfaces 40
A vertical portion 40b is formed between them, and the vertical portion 40b is formed with a gap Z so as to be slightly lower than the lower surface of the third horizontal plane 32, as shown in FIGS.
(Approximately 5 mm), and the third horizontal plane 32 is provided by an impact when the packing box 10 containing the packing article 13 falls.
Of the vertical portion 40b contacts the upper end of the vertical portion 40b.
In this way, the above-mentioned impact can be absorbed by exerting the supporting force secondarily. If there is no gap between the lower surface of the third horizontal surface 32 and the upper end of the vertical portion 40b, as shown in FIG. There is a possibility that the package 13 may be damaged and cause a failure.

Referring again to FIGS. 2 and 3, reference numeral 46 denotes a flank which is continuous with the third vertical surface 24 and can be bent from the bending line W. This flank 46 is shown in FIG.
As shown in (a), when the packaged article 13 has a projection 48 such as a wiring connection terminal, the projection 48 is attached to the packaged article 13.
Is slid along the third vertical surface 24 when it is placed on the third horizontal surface 31, and when it comes to the flank 46, the flank 46 is bent and the projection 48 is fitted into the recess. It is provided to be able to. When the packaged product 13 is lifted and taken out, the projecting portion 48 smoothly reaches the third vertical surface 24 along the bent portion of the flank 46 and slides along the third vertical surface 24. The package 13 can be easily taken out. If the flank 46 is used as shown in FIG.
If the hole 50 is formed instead of the hole 50, it takes a lot of time to pull out the tip of the protrusion 48 from the hole 50 and reach the third vertical surface 24.

FIG. 12 shows the packing holding member 1 shown in FIG.
1. After the packaged goods 13 and the packing holding member 11 are stored in the packing box 10, various small items such as the toner case 52, the developing device 53, or the partitioner 55 are placed on the packing holding member 11 above. Etc., but there is an empty space 57 in which only one place cannot be filled. If the empty space 57 is left as it is, for example, the toner case 52 moves inside, so it is necessary to put something in this empty space 57. It can be costly, and making a box out of cardboard is expensive. Therefore, in this embodiment, as shown in FIG. 15, the problem was solved by inserting a toner stopper 58 formed by bending a cardboard material into an L shape.

That is, as shown in FIG. 16A, the height of the toner stopper 58 to be inserted into the empty space 57 is slightly higher than the upper end of the height of the packing box 10 (only by h). As shown in FIG. 16B,
When the inner lid 10a of the packing box 10 is rotated so as to close, the upper end of the toner stopper 58 is pushed and falls down, and the inner lid 10a is completely closed as shown in FIG. When the toner stopper 58 reaches the upper end, the upper end of the toner stopper 58 is
And the vertical portion of the toner stopper 58 is tilted diagonally and inclined. For this reason, the toner case 52 is prevented from moving inside, and the upper end and the lower end of the partitioner 55 are also regulated by the toner stopper 58, so that the toner case 52 shown in FIG.
(C) There is no displacement on the middle left side.

As shown in FIG. 17A, a toner cartridge 59 is accommodated in the toner case 52, and the end of the toner case 52 travels upward slightly (m) longer than the height of the toner case 52. A pad 60 is disposed, and a bending line is formed in an intermediate portion of the pad 60 (a portion indicated by an arrow d in FIG. 3) in order to facilitate bending. For this reason, as shown in FIG. 17B, when the inner lid 52a of the toner case 52 is rotated so as to close, the upper end of the pad 60 is pushed and deformed in a shape of a letter from the above-mentioned bending line. As shown in FIG. 17C, when the inner cover 52a is completely closed and arrives on the toner cartridge 59, the pad 60 is bent most at the middle portion and comes into contact with the shutter portion 59a of the toner cartridge 59. As shown in FIG. 18, when the pad 60 is absent and a shock is applied in the direction indicated by the arrow, the shutter 59a of the toner cartridge 59 can be prevented from opening (toner spilling).

A drop test of the packing box 10 containing the packaged goods 13 was performed using the packing holding member according to the embodiment having the above-described configuration. The test result proves that the packing box 10 can sufficiently withstand an impact. Was to do. The test is 40c drop height
m, and a total weight of 19 kg, and performed at a drop position as shown in FIG. 19, where a is a corner, b, c, d are ridges, e is a front,
He is after, G is right, J is left, Li is bottom, and N is heaven.
