Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a packaging container for articles, and more particularly to a packaging container for storing a large number of articles such as speaker units for audio equipment for transportation or the like.

BACKGROUND TECHNOLOGY Conventionally, packaging containers have been generally used as containers for storing and packaging various items for transportation, etc., in which cardboard partitions are arranged inside a cardboard case to provide the required storage space for the items. . In this case, if the items to be stored have a simple shape such as a plate or a cylinder, the shape of the partition plate,
The structure may be simple and does not pose any particular problems, but in the case of products with complex external shapes such as speaker units for audio equipment,
Special efforts were required to efficiently store a large number of these items and to package them in a manner that would not damage them.

FIGS. 4 and 5 show an example of such a conventional packaging container, with FIG. 4 being a perspective view of its appearance, and FIG. 5 being a plan view with the lid removed.

As shown in FIG. 5, this packaging container is made up of a rectangular box-shaped cardboard case 01 with partition plates 02 and 03 provided therein. The partition plate 02 is a rectangular corrugated board bent to form a plurality of dovetail shapes suitable for accommodating speaker units. A plurality of partition plates 02 are vertically arranged inside the cardboard case 01, and another flat rectangular partition plate 03 is arranged between each partition plate 02. The speaker unit 10 is housed in the dovetail space 04 thus formed.

However, in such a packaging container, since the partition plate 02 is formed by bending a long corrugated board at many points, there is a drawback that the strength against the weight of the article is not sufficient. In addition, a large amount of material (cardboard) is required, and the storage efficiency in the long side direction of the cardboard case 01 is poor, resulting in a long length. Furthermore, partition plate 0
Another problem is that it requires a lot of man-hours to bend at multiple locations.

Problems to be Solved by the Invention The present invention aims to solve the problems of conventional packaging containers as described above, and to provide a packaging container with excellent strength and storage efficiency.

Means for Solving the Problems The packaging container of the present invention, like the conventional example described above, has a box-shaped cardboard case that is partitioned parallel and perpendicularly with partition plates to provide a plurality of storage spaces for items. be. However, in the present invention, the partition plate is provided with a plurality of notches perpendicular to the center line from one long side of the rectangular corrugated board at equal pitches in the long side direction, and from the other long side. A similar cut is made at a position corresponding to the middle of the above cut, and the corrugated board is further folded in half from a center line parallel to its long side, and then set in the cardboard case with the fold facing down. It is. Further, on the inner edges of both sides parallel to the partition plates of the cardboard case, there are rectangular cardboard wall plates in which the same notch as described above is made from the upper long side at a position corresponding to the middle of the cuts in the opposing partition plate surfaces. erected. Both edges of each cut in the partition plate and the wall plate are bent at a substantially right angle toward the article storage space.

Effect: With the above configuration, spaces suitable for accommodating speaker units differently from each other are formed in each row formed between the partition plate and the wall plate and between the partition plates. In addition, the speaker units housed in each row are oriented in the same direction as the speaker units housed in other rows.This packaging container has excellent storage efficiency, has high container strength, and is easy to process and manufacture. can be provided.

Embodiment Hereinafter, based on the drawings showing the embodiment of the present invention,
The configuration of the present invention will be explained in more detail.

Figures 1 to 3 show one of the packaging containers according to the present invention.
An embodiment is shown, and FIG. 1 is a plan view with the lid removed. The external appearance of the packaging container of the present invention is the same as that of the conventional packaging container shown in FIG. 4 above, so illustration thereof is omitted.

As seen in FIG. 1, the packaging container of this embodiment has a box-shaped cardboard case 1 partitioned by a plurality of (five in the illustrated example) partition plates 2 parallel and perpendicular to each other. Wall plates 3, 3' are erected on the inner edges of both sides parallel to the partition plate 2, and speaker units are housed differently in each row, and the speaker units housed in each row are connected to the speaker units housed in the other rows. It is designed so that it can be stored facing the same direction as the unit.

Figure 2 shows the expanded shape of the partition plate 2.
The partition plate 2 is formed of a rectangular corrugated board, and a plurality of rectangular notches 5 (two in the illustrated example) having the required width and depth are formed from one long side toward the central folding line 6. are provided at equal pitches in the long side direction. Further, on the other long side, a plurality of similar partitions 4 (three in the illustrated example) are provided at positions corresponding to intermediate positions of the partitions 5 toward the central folding line 6. . In the figure, the center line parallel to the long side indicated by a broken line is a fold line 6 obtained by cutting the corrugated board in half, and the rectangular corrugated board is folded in half along this fold line 6 to form the partition plate 2. A plurality of pieces (five pieces in the illustrated example) are installed at required intervals in the cardboard case 1 parallel to the long side of the cardboard case 1 with the folding line 6 facing downward. Note that a triangular partition 7 may be provided at the end (short side) of the folding line 6.

Figure 3 is a front view of the wall plates 3, 3';
3' is a rectangular corrugated board with partitions similar to the partition plate 2 on the upper side, and 3 in A of the same figure is a plurality of partitions corresponding to the partitions 5 of the partition plate 2 (in the illustrated example). 2) partitions 5' are inserted, and 3' in (b) is one in which a plurality of (three in the illustrated example) partitions corresponding to the partitions 4 of the partition plate 2 are inserted. These wall plates 3 and 3' are erected along the inner edges of both long sides of the cardboard case 1, and the partitions of the wall plates 3 and 3 are placed at intermediate positions between the partitions 4 and 5 on the two sides of the partition plates. 4' and 5' should correspond. That is, in the illustrated example, the wall plate 3 having two partitions 5' is placed on the side of the partition plate 2 that has three partitions 4, and the wall plate 3 has two partitions 5' on the side that has two partitions 5. The wall plates 3' having 4' are placed opposite each other. (See Figure 1) The partitions 4, 5, 4', 5' provided on the partition plate 2 and the wall plates 3, 3' are located at the bottom (innermost part).
is further cut slightly laterally, and folds 8 in the depth direction shown by chain lines in the figure are provided on both sides to form folded pieces. This fold 8 is a perforation, and when the partition plate 2 and the wall plates 3, 3' are set upright in the cardboard case 1, the other partition plate 2 or the wall facing each other is separated from this fold 8. It is bent approximately 90 degrees toward the plates 3 and 3'. Further, at both ends of the partition plate 2 and the wall plates 3 and 3', folds 9 are provided by perforations along the short sides, and these folds 9 are also approximately
It is bent by 90 degrees and comes into contact with the inner edge of the short side of the cardboard case 1 to ensure that the partition plate 2 and the wall plates 3, 3' stand upright, and to strengthen the strength of the corners of the cardboard case 1.

Thus, by installing the partition plate 2 and the wall plates 3, 3' in the cardboard case 1, a package having a large number of storage spaces 11 in which the speaker units 10 can be alternately stored in each row, as shown in FIG. 1, is created. A container is constructed. In this illustrated example, 5 pieces/1 row x 6
A row of 30 speaker units 10 can be accommodated. As is clear from the figure, in each row, the base small diameter portion (magnetic portion) of the speaker unit 10 is bent from the fold 8 of the partition plate 2 or wall plate 3, 3'. It fits into the space formed by the ′ part, and the large diameter parts are stored with their backs stacked on top of each other.
The same number of partition plates can be stored in a shorter length than the conventional partition plate shown in FIG. 5, in which the large diameter portions overlap less.

FIG. 6 shows another embodiment of the partition plate shown in FIG. 2, in which partitions 5 are provided at equal pitches from the center line of a rectangular corrugated board to one long side, and The notch 4 is the notch 5 toward the long side of the
It is provided at a position corresponding to an intermediate position. Opening folding pieces 8 are formed on both sides of the cuts 4, 4'5, 5'. By folding this in half along the center line 6 and placing it in parallel inside the cardboard case with the folded edge facing up, that is, in the opposite direction to the partition plate shown in Fig. 2 above, the same partition as described above can be created. It has the function of a board.

Effects of the Invention As explained above, in the packaging container of the present invention, a cardboard partition plate folded in half is used, and its length is shortened, so that its strength is increased. Also,
Storage efficiency is improved and material costs can be reduced. Furthermore, since there is no need to bend a long corrugated board, the number of manufacturing steps can be reduced. in this way,
The present invention solves the problems of the conventional technology and has an extremely large practical effect.
