(Embodiment) A first embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

1A is a sheet material made of paper or plastic such as cardboard or cardboard, and in this case, it is
It has a rectangular aspect ratio.

In Figure 1, which is a developed view of the partitioned packaging material before assembly, the sheet material 1A has been cut and creasingly processed as described below. The cuts are provided parallel to each other at a predetermined interval in the central portion of the sheet material 1A excluding the peripheral portion.

3 denotes two orthogonal folds perpendicular to each parallel cut 2, each provided a predetermined distance inward from both ends of each parallel cut 2, and folds the sheet material 1A to one side (front side) thereof. It's becoming like that.

4 is a diagonal fold, and each end point a of one parallel cut 2 among a pair of adjacent parallel folds 2, 2
and a point b where the other parallel cut 2 intersects with the orthogonal fold 3, so that the sheet material 1A is bent toward the other surface (back surface).
This diagonal fold line 4 is formed by providing a cut (half cut) deep enough to reach approximately the middle of the thickness of the sheet material 1A, so that the sheet material 1A can be easily folded in two along the diagonal fold line 4. .

For convenience of explanation, both edges of the sheet material 1A on the side parallel to the parallel cut 2 will also follow the parallel fold 2.

Reference numeral 5 denotes a parallel partition forming portion, which corresponds to each region surrounded by a pair of adjacent parallel cuts 2, 2 and a pair of orthogonal folds 3, 3.

Next, the operation of the above configuration will be explained.

The folding partitioned packaging material is unfolded as shown in FIG. 1 and shipped from the manufacturing factory in sheet form.

Therefore, in order for the user to fold this sheet material 1A and assemble it into a packaging material with partitions, the user first grasps the outer portions of the two orthogonal folds 3, 3 with both hands, and folds the outer portions of the sheet material 1A into the orthogonal folds 3, 3. Along the same lines, the sheet material 1A is bent toward the front side to form a crease. Next, when these orthogonal folds 3 and 3 are folded back,
Due to this movement, each of the four diagonal folds is folded into sheet material 1.
It is bent towards the back side of A.

When each of the diagonal folds 4 is completely bent in half, both outer portions of the sheet material 1A are erected to face each other, as shown in FIG. The desired packaging material with partitions is assembled in a one-touch manner.

The assembled packaging material with partitions will lose its bent shape if you let go, but this assembled state can be maintained by placing it in a normal packaging box A without partitions as shown in Figure 2. .

As described above, according to the above configuration, the packaging material with partitions is
Since the process is completed by simply punching and creasing a single sheet material 1A as a raw material, the manufacturing cost is significantly reduced compared to the conventional method, and the sheet material 1A is cut from the sheet material. Cutting loss during cutting is also minimal.

Furthermore, if the partitioned packaging material is rolled out into a flat sheet, it will not be bulky, and storage and transportation costs can be reduced compared to conventional packaging materials.

Next, FIGS. 3 and 4 show a second embodiment of the present invention, and the main difference from the first embodiment is that the partitioned packaging material of the first embodiment has The bottom portions are arranged one after the other, and intermediate partitions are provided in the bottom portions in a direction intersecting each parallel partition forming portion 5, so that the partition structure is shaped like a lattice.

The rectangular sheet material 1B has a central portion a in its longitudinal direction that forms a parallel partition, and side portions b that form a bottom portion and a middle partition, respectively.

A slit-like parallel cut 2 is made in the center part a, leaving a predetermined width at both the left and right ends (in the figure).
A plurality of strips are provided in the horizontal direction at predetermined intervals.
Then, in the parallel partition forming portions 5 sandwiched between a pair of adjacent parallel cuts 2, 2, there are parallel partition forming portions 5 at the intermediate locations in the longitudinal direction, except for the uppermost one.
A slit 6 with a length half the width of the parallel cut 2
It is set perpendicular to.

Similarly to the first embodiment, the central portion a has parallel cuts 2, orthogonal folds 3, and diagonal folds 4.
However, in this case, a cut 2a of a predetermined length is made from each end of one cut 2 of a pair of parallel cuts 2, 2 toward the other parallel cut 2.
is provided, and the diagonal fold 4 is formed by this cut 2a.
and the point b where the other parallel cut 2 and the orthogonal fold 3 intersect.

At both left and right edges of the center portion a, bottom forming pieces 8 are integrally connected via bottom shape folds 7, and furthermore, at the edges of the bottom forming pieces 8, there are partitions. The partition pieces 10 are integrally connected to each other via forming folds 9.

As will be described later, the two folds 7 and 9 on the edge of the partition piece 10 interfere with each other when the two folds 7 and 9 are bent at right angles toward the back side of the sheet material 1B. A slit 11 is provided at the location where the slit 6 is fitted.

Next, the operation of the above configuration will be explained.

First, hold both outer parts of each parallel cut 2 of the sheet material 1B with both hands, first bend it toward the front side of the sheet material 1B to create a crease, and then fold it back toward the back side. As in the case of the first embodiment, the parallel partition forming portions 5 are erected parallel to each other.

Therefore, both hands holding the sheet material 1B,
When the sheet material 1B is shifted to the outside of the bottom-forming fold 7 and a bending force is continued to be applied to the sheet material 1B, the bottom-forming fold 7 is bent at a right angle, and the bottom portion of the folded packaging material is formed. Ru.

Next, the hands holding the sheet material 1B were further shifted to the outside of the partition forming folds 9, and
The partition piece 10 is bent at right angles to the bottom forming piece 8. At this time, the middle partition piece 10 will interfere with each parallel partition forming part 5, but since the slits 6 and 11 are provided in advance at the interference points,
By fitting these slits together, as shown in FIG. 4, a partitioned packaging material having a bottom and a middle partition extending between each parallel partition forming part 5 is completed. .

By providing the partitions in this way, the packaging material with partitions is given self-shape retention, which allows it to maintain its assembled state by itself, unlike the packaging material of the first embodiment.

Therefore, after completing its role as a protective partition for the products inside the packaging box during transportation, the packaging material with partitions removed from the packaging box for each product can be effectively reused, for example, as a display stand for the product at a store. It can be utilized.

In this case, the bottom forming pieces 8, 8 constituting each half of the bottom of the partitioned packaging material have the same width, but if the width ratio and the position of the slit 6 are changed in accordance with this width ratio, the middle partition The installation location can be moved arbitrarily.

Furthermore, in this embodiment, by interposing the third cut 2a between both ends of the parallel cut 2 and the diagonal fold 4, the difference between FIG. 2 of the first embodiment and FIG. As can be understood by comparing it with Figure 4,
The structural strength and appearance of the side parts of the finished packaging material with partitions are improved.

5 and 6 show a third embodiment of the present invention, and the difference from the second embodiment is that another partition is provided in parallel to the direction in which the partition is formed. It's somewhere.

Therefore, the sheet material 1C includes the sheet material 1C described above.
The width of the right side part of B is widened, a partition forming part c is provided, and three partition forming folds 13, 14, 15 for forming the partition 12 on the studs are provided parallel to each other at a predetermined interval. There is. A slit 16 is provided in the middle partition forming fold 14 in a direction perpendicular to the fold at a location where it interferes with each parallel partition forming part 5.

The order of assembling this sheet material 1C into a packaging material with partitions as shown in FIG. 6 is similar to that of the second embodiment, and its explanation will be omitted.

Figures 7 and 8 show "strawberry packs" using commonly used transparent plastic containers.
A packaging material with partitions according to a fourth embodiment is shown for displaying four items at a time at a store.

The difference from the second embodiment is that the parallel partition forming portion 5
It is sufficient to have them in the middle and both ends of the partitioned packaging material, so two of the five parallel partition forming parts 5 are located in the hollow parts 17 formed by hollowing out the sheet material 1D. .

[Effects of the invention] As is clear from the above explanation, the packaging material with partitions of the present invention uses a single sheet material as a material, provides multiple parallel cuts in it, and cuts adjacent parts of the partitioned packaging material. A parallel partition forming portion is formed between each set of cuts, and
By bending the sheet material along fold lines provided at predetermined locations on the sheet material, each of these parallel partition forming portions can be made to stand up parallel to each other.

Therefore, unlike the conventional structure in which a large number of paper strips with slits are fitted together and foldable, the manufacturing process is significantly reduced, and the cutting of the material sheet is greatly reduced. In addition to reducing losses, assembly can be done almost in one-touch manner, and overall, the manufacturing cost of packaging materials with partitions and the effort of assembling them into packaging boxes can be significantly reduced.

Once assembled, the packaging material with partitions has self-shape retention, unlike conventional packaging materials.
Not only does it serve as a simple partitioning material to protect products inside packaging boxes during transportation, but after completing this role, each product can be removed from the box and used as an extremely effective stand for displaying products in stores. It can also be reused.

Furthermore, since the material is supplied as a single flat sheet before assembly, the storage and transportation costs can be significantly reduced compared to conventional methods, and the present invention is an excellent invention that brings many benefits.
