Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a packaging box equipped with a retractable partition.

(Prior Art) A rectangular paper board 28 as shown in FIG.
There is a method in which a large number of slits are provided at regular intervals, and a partition in which other rectangular plate pieces 30 are inserted into these slits is housed inside a packaging box such as a cardboard box.

In addition, a partition described in Japanese Utility Model Publication No. 51-47575 is known as shown in FIG. 7, and this partition is installed inside a packaging box.

As shown in the drawings, these conventional partitions are installed in a packaging box with the squares expanded to the maximum extent possible in a grid pattern.

(Problems with the Prior Art) The former example has general drawbacks such as the partition cannot be folded, requires time and effort to assemble, and lacks sufficient strength.

In addition, since the surrounding area is open, the entire area is not partitioned into a four-sided enclosure, and the surrounding squares 32 are U-shaped and cannot accommodate articles.

Furthermore, since the surrounding squares 32 cannot be used, material is wasted, and the number of squares 32 is small.

Furthermore, although the latter partition itself has advantages over the former, the other two sides remain open, so there is still a waste of material, and although the number of squares increases, it is not sufficient.

In addition to the above-mentioned general problems, these conventional examples reduce the space of the partition by reducing the size of the partition to some extent and inserting it inside the packaging box, which allows for smaller packaging. No solutions have been found to enable the use of boxes and to increase the number of squares.

(Technical Problem of the Invention) The main purpose of this invention is to provide a packaging box in which the compartments of the partitions are reduced to a certain extent without causing any inconvenience.

Another object is to reduce the size of the packaging box that accommodates the partitions.

(Technical Means of the Invention) The basic structure of this invention is to provide a rectangular sheet with multiple folds in its width direction, and fold both outer pieces inward through the folds closer to the outer sides to form a rectangular sheet. Then, the inner single pieces adjacent to both outer folds are bent inward at right angles through the inner second folds adjacent to both outer folds. Then, each single piece provided between the second folds on both sides is folded into an uneven shape when viewed from the plane through the respective folds, and each convex surface portion in the longitudinal direction of the sheet folded into an uneven shape and A plurality of separate sheets are arranged parallel to each other at regular intervals on both outer pieces, and the length of one unit of the square of the sheet is alternately bent in the above-mentioned uneven shape in the length direction. A protruding portion is made to protrude in correspondence with the length L, and each convex surface portion and both outside pieces of the sheet bent in an uneven shape are bonded between the other sheets, leaving the protruding portion. A retractable partition is provided, and the retractable partition is compressed to some extent by slightly pressing the sheets arranged parallel to each other in the packaging box from both sides, and the packaging box is compressed to some extent and accommodated.
The packaging box is equipped with a retractable partition with the protruding portion slightly abutting against the inner wall of the packaging box.

(Effect of the invention) In a packaging box such as a cardboard box, sheets placed parallel to each other are slightly pressed from both sides to compress them to some extent, changing the rectangular cells into diamond shapes and reducing the overall size of the partition. It is placed inside the box, and the protruding part is slightly abutted against the inner wall of the box.

(Example of the invention) The details of this invention will be explained below with reference to the attached drawings.

In this invention, the devised partition described below is compressed to some extent and placed inside a packaging box such as a cardboard box.

Therefore, first, the structure of the partition will be explained.

As shown in FIG. 1, a rectangular sheet 10 is prepared as one of the materials for forming the partition cells.

This sheet 10 has a plurality of folds 12 in the width direction.
a, a second fold 12b, and a fold 12c are provided.

The outer pieces 14 provided on the outside of the folds 12a on both sides serve simply as glue margins, so they are smaller than the other single pieces 16 described later, but the single pieces 16 and their The sizes may be the same.

Needless to say, the width and length between the folds 12a and 12b and between the folds 12c and 12c provided between the outer folds 12a on both sides determine the size of the square 24 of the partition.

Therefore, both outer pieces 14 are bent inward at right angles as shown in FIG. 16 are bent inward at right angles through the inner second folds 12b adjacent to the outer folds 12a, and each The single pieces 16 are each folded into an uneven shape when viewed from the plane through fold lines 12c, thereby providing a sheet 18 which is folded into an uneven shape.

Then, a plurality of other sheets 22 are attached at regular intervals (corresponding to the width of the single piece 16) to each convex surface portion 20 and both outer pieces 14 in the longitudinal direction of the sheet 18 that has been bent into an uneven shape. The protrusions 26 are arranged in parallel to each other and are alternately protruded in different directions corresponding to the length L of the squares 24 of one unit of the sheet 18 which is bent in the uneven shape in the length direction,
A retractable partition is constructed by bonding each convex surface portion 20 and the outer piece 14 of the sheet 18 folded into an uneven shape between the other sheets 22, leaving this protruding portion 26 ( (See Figure 3).

Therefore, as shown in FIGS. 4 and 5, the partition having the above-mentioned structure is made such that the retractable partition is pressed slightly from both sides of the sheet 22 arranged in parallel inside a packaging box such as a cardboard box. The partition is compressed to some extent to accommodate the partition, and the protruding protrusion 26 is slightly abutted against the inner wall of the packaging box.

(Effects of the invention) Since this invention has the above configuration, it has the following advantages.

Even if the partition is compressed to some extent and placed in a packaging box, there are protrusions on both sides of the partition, so these protrusions will come into contact with the inner walls on both sides of the box, albeit gently. The partition maintains a certain compressed state without restoring to the expanded state.

Therefore, since the partitions can be used in a compressed state to some extent, the size of the packaging box used can be reduced by the size of the compressed partitions, contributing to material savings for packaging boxes.

Further, since a triangular square is formed by the inner wall of the packaging box, the protrusion of the partition, and a single piece on the outside of the partition, the number of squares can be increased.

In addition, since the squares are formed into diamond shapes, the packaging function is particularly excellent for diamond-shaped items, and unlike the conventional case where the partitions are stored in a fixed state inside the packaging box, the partitions can be stored in a slightly pressed state. Since it is housed in a warm and free state, it has an inherent restoring force, and as a result, it has excellent cushioning properties and is less likely to be damaged by rubbing, even if it is an article that is easily scratched.
