Since the first problem solving means of the present invention has the above-described configuration, it can be folded made of temporary plastics in which an inner piece for a packaging partition with one outer side piece and an outer piece for a packaging partition are bonded. By cutting the packaging partition with a blade, it is possible to easily obtain a foldable packaging partition made of plastics, which can contribute to the rationalization of productivity.

Although the adhesive once cured may be softened and melted at high temperatures such as in the summer, a margin is formed around the margin part, so the molten adhesive is the margin, in other words Since there is a margin, it can be absorbed by the margin.
Therefore, there is no possibility that the melted adhesive will ooze out from the adhesive margin part or the adhesive part, and there is no possibility that it will vaporize and adversely affect the package.

In addition, since no adhesive is applied to the cutting margin, the adhesive does not adhere to the blade during cutting with the blade, making it easier to manage the blade, and the cutting margin is the glue margin. Since it can also serve as a part of the surrounding margin part, formation of the margin part of the glue margin part can be enjoyed and it can contribute to simplification of the production process.

The fifth problem-solving means of the present invention has the effect of the first, second, third, or fourth problem-solving means, and the adhesive is discontinuous such as a dot state. Can save.

The sixth problem solving means of the present invention has the effect of the first, second, third, fourth or fifth problem solving means, as well as the end in the fold direction of the inner piece for the packaging partition in the flat state. Because it is temporarily fixed by a non-metallic locking material that suppresses the lift, the inner piece for the packaging partition that has been processed into a flat state can be prevented from unfolding, contributing to the assurance of the bonding process. it can.
In addition, since the inner piece for the packaging partition is temporarily fixed with a non-metallic locking material so that it does not unfold, the material of the temporary fixing portion is discarded in the production process, but is used for temporary fixing. Since this is a non-metallic locking material, it can be used for recycling as well as the plastic sheet constituting the packaging partition without removing and locking the locking material.
Therefore, it is possible to contribute to the omission of the sorting work in preparation for recycling.

In order to prevent the adhesive from melting and partly adhering to the packaged item or causing the adhesive that has oozed out to vaporize to affect the packaged item, This was realized by applying an adhesive with the blank portion remaining.

4-5, the sixth glue margin 12- also serving as a horizontal piece of the packaging partition outside the tenth fold 10-10
6 is provided with an inner piece A1 for foldable packaging partition provided alternately (FIGS. 2 and 5).
See).
The vertical piece described above determines the vertical width of the partition for packaging, and is determined according to the size of the article to be packaged, which is equal to the vertical width of the mesh S (see FIG. 10).

Therefore, it goes without saying that each margin part serving also as a horizontal piece of the packaging partition and each vertical piece of the packaging partition are combined to form the packaging partition cell S (see FIG. 10).

Regarding the step of providing the inner piece A1 for the folding packaging partition, five units of the folding plastic packaging partition M having four grids S in a row in the horizontal direction are connected in advance. Although the example has been described, the basis of the present invention is to obtain one unit of plastic packaging partition M having two grids S in one row in the horizontal direction. As a precaution, the inner piece A1 for the foldable packaging partition for the two cells S is spread.

The first fold 10-1, the second fold 10-2, the third fold 10-3, and the fourth fold are spaced apart from one side to the other side of the inner piece A for packaging partition. Fold line 10-4, fifth fold line 10-5 and sixth fold line 10-6 are formed, and the outer side of the first fold line 10-1 also serves as a horizontal piece of the packaging partition. The first glue margin 12-1, the first vertical piece 14-1 of the packaging partition between the first fold 10-1 and the second fold 10-2, the second fold 10-2 And the third fold 10-3 between the second fold margin 12-2, which also serves as a horizontal piece of the packaging partition, and between the third fold 10-3 and the fourth fold 10-4 The second vertical piece 14-2 of the partition, the third glue margin 12-3 that also serves as the horizontal piece of the packaging partition between the fourth fold 10-4 and the fifth fold 10-5, the fifth Fold 10-5 and 6th Fold 1
The fourth adhesive margins 12-4, which also serve as horizontal pieces of the packaging partition, are alternately arranged outside the third vertical pieces 14-3 and the sixth folds 10-6 of the packaging partition between 0-6. It is provided.

(Step of obtaining an inner piece for a flat packaging partition)
In the subsequent process, the inner piece A1 for packaging partition and the outer pieces B1 and B2 for packaging partition are polymerized and bonded. Bend into a shape.

A first margin part 1 in which the inner piece A1 for a foldable packaging partition also serves as a lateral piece of the packaging partition
The sixth glue margin 12-6, which also serves as the horizontal piece of 2-1 and the packaging partition, is bent in a plate shape toward the inside (see FIGS. 3 and 5).

On the other hand, a pair of a first glue margin 12-1 that also serves as a horizontal piece of the packaging partition and a second glue margin 12-2 that also serves as a lateral piece of the packaging partition, and a third that also serves as a lateral piece of the packaging partition. A pair of the fourth margin part 12-4 that also serves as a horizontal piece of the packaging margin and a fifth margin part 12-5 that also serves as the lateral piece of the packaging partition and the packaging partition Fold in a flat state via the first fold 10-1 to the sixth fold 10-6 so that the pair of sixth glue margins 12-6 that also serve as horizontal pieces are in an opposing state. As a result, a flat inner partition piece A2 is obtained (see FIGS. 3 and 5).
.

The intent of obtaining the flat inner packaging piece A2 is nothing other than obtaining an environment that facilitates polymerization in preparation for bonding the outer packaging piece Bb with the secondary adhesive portion in the subsequent process.
Although the folds are less likely to unfold when the inner piece A2 is pressed, the end of the inner piece A2 for flat packaging partitions in the direction of the fold is sewn to prevent the folds from being unfolded. It is preferable to temporarily fix it with a non-metallic locking material a for suppressing lifting with a cloth tape or the like (see FIG. 3).

On the other hand, by temporarily fixing with a non-metallic locking material a for suppressing lifting,
Although the inner piece A2 for packaging partition can be maintained in a flat state, there is an advantage in the production process,
Speaking of the product itself, it becomes an obstacle, so it is necessary to remove it in the subsequent process.

However, since it is not always easy to remove the non-metallic locking material a for suppressing lifting, the non-metallic locking material a for suppressing lifting is provided near the end of the inner piece A2 in the fold direction. However, by removing a part of the inner piece A2 close to the end without removing it, the non-metallic locking material a for suppressing lifting is prepared for reuse together with a part of the inner piece A2.

In general, in order to recycle the material to be cut (industrial waste), it is melted and made into a plastics raw material. The advantage of being able to recycle and dispose of them without removing them from the inner piece A2 is achieved.

(Step of obtaining a continuous inner piece for packaging with an adhesive portion)
This step is a pre-step provided for bonding the flat inner partition piece A2.

Then, the outer piece Ba for the packaging partition with a primary adhesive portion is provided in a row to obtain one outer piece Bb for the packaging partition with a secondary adhesive portion (see FIG. 4).

Although it has been described that the cutting blank portion F remains, the blank portion F also serves as a part of the blank portion D between the vertical adhesive portions E as shown in FIG.
.
The above-described cutting blank portion F is a portion to be cut by the blade T in a subsequent process, and is intended to prevent the hot melt type adhesive G from adhering to the blade T (FIGS. 8 and 9).
See).

The adhesive part E is formed in the vertical direction on the left side in the drawing, but the hot melt type adhesive G is not necessarily inexpensive, so the adhesive G is intended to reduce the production cost. Savings.
On the other hand, the other bonding portions E are two in order to improve the bonding function.
Although the bonding portion E is in the vertical direction in the drawing, it may be formed in the horizontal direction if an adhesive function can be obtained.

Although illustration is omitted, in order to save the adhesive G, it is also planned to form the adhesive portion E in a dot state.

As the work procedure, the step of obtaining the outer piece and the inner piece first, the step of obtaining the inner piece for the folding packaging partition, the step of obtaining the inner piece for the flat packaging partition have been described, but the continuous bonding It will be readily understood by those skilled in the art that the process of obtaining the inner piece for part packaging is free to perform prior to these processes and is merely a modification of the work procedure.

(Step of obtaining an inner piece for a packaging partition with one outer piece)
Each adhesive margin exposed on one side of the inner piece A2 for flat packaging partition is bonded to each bonding portion E of the outer piece Bb for packaging partition with a secondary bonding portion via an adhesive. By doing
An inner piece A3 for packaging partition with one outer side piece is obtained (see FIGS. 5 and 6).
Each glue margin exposed on either side is the first glue margin 1 in FIGS. 5 and 6.
2-1, the third margin part 12-3, and the fifth margin part 12-5.

(Procedure for obtaining a foldable packaging partition made of temporary plastics)
Two inner pieces A3 for packaging partitions with one outer side piece are arranged symmetrically.
Next, the adhesive G of the inner piece A1 for packaging partition of the inner piece A3 for packaging partition with one outer side piece on one side and the inner piece A3 for packaging partition with the other outer side piece on one side is not applied. Each side margin 12-2,
12-4 and 12-6 are bonded through the adhesive G.

Further, the above-described steps are repeated, and the third, fourth, and fifth inner side pieces A3 for packaging partitions with outer side pieces are bonded symmetrically.
Then, the other outer piece Bb for the packaging partition with the second secondary adhesive portion is bonded to each adhesive margin portion on the non-application side of the adhesive of the inner piece A3 for the packaging partition with the fifth outer side piece on the fifth side. Is bonded to each other to obtain a foldable packaging partition K made of 5 units of temporary plastics having 20 meshes S (see FIGS. 6 and 10).

In the above process, it has been described that the inner pieces A3 for packaging partitions with one outer side piece are arranged symmetrically, and this point will be further described.

When the inner piece A3 for packaging partition with the second one-side outer piece is bonded to the inner piece A3 for packaging partition with the first one-side outer piece, for the packaging partition with the second one-side outer piece 18 inside pieces A3
It is necessary to invert it by 0 degrees and bond it.
This is because, in the case of the embodiment, each vertical piece of the flat inner packaging piece A2 is bent toward the left side in the drawing (see FIG. 10).

Therefore, when the inner piece A3 for packaging partition with one side outer piece with the vertical piece bent on one side is laminated as it is, the vertical piece of the inner piece A3 for packaging partition with each one side outer piece is a staircase. And the packaging partition M cannot be extended.
Therefore, it is necessary to invert the inner piece A3 for packaging partition with one outer side piece laminated as described above by 180 degrees for every lamination.

Since the basis of the present invention is one unit of plastic packaging partition M provided with two squares S in the horizontal direction as described above, the second to fifth secondary adhesive portions are provided. It is free to omit or increase / decrease the outer piece Bb for the attached packaging partition.

By removing the non-metallic locking material a for suppressing lifting from the foldable packaging partition K made of temporary plastics, the plastics having a large height are prepared in order to accommodate tall packages. It can be used for foldable packaging partitions.

(Process to remove non-metallic locking material for lifting prevention)
The non-metallic locking member is removed together with a part near the end of the packaging partition M by cutting the end line L of the temporary folding partition K made of plastics with a blade (see FIG. 8). ).

Also in this process, because the cutting tool T is used for cutting in the production process, the non-metallic locking material a
The attachment position is preferably a non-adhesive part.
As described above, the mounting position of the non-metallic locking material a is the inner piece A for a flat packaging partition.
Since it is close to the end of 2, the outer piece Bb for the packaging partition with a secondary adhesive portion is preferably located at the periphery of the adhesive portion E and corresponding to the end of the blank portion D (FIGS. 3 and 4). See).

(Cutting process)
Foldable packaging partition K made of the above-mentioned temporary plastics through a blank space F for cutting
By cutting the four dividing lines P with the blade T, 20 squares S consisting of 5 units
5 sets of plastic folding foldable packaging partitions M can be obtained simultaneously (see FIGS. 9 and 10).
Needless to say, the positions of the four dividing lines P coincide with the margin F for cutting of the outer piece Bb for the packaging partition with the secondary adhesive portion.

In Example 1, the inner piece A2 for flat packaging partitions and the outer piece B for packaging partitions with secondary adhesive portions
In preparation for bonding b, an adhesive portion E is formed on the outer piece Bb side for the packaging partition with a secondary adhesive portion, leaving a blank portion D around the periphery. Is provided on the side of the inner piece A2 for flat packaging partitions.
The process of obtaining the inner piece A3 for the packaging partition with the one-side outer piece is the opposite procedure, and there is no change in the essence of the invention.
Other steps are the same as those in the first embodiment.
