Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a blank for packaging boxes made of cardboard or other cardboard.

(Prior art) In conventional corrugated boxes and paper containers, the assembling of the box and the introduction of the inner assembly partitions (inner partitions) have been molded integrally with the box so that the two operations can be performed at the same time. It is publicly known. (Jitko No. 54-25234, Jitko No. 56-42171). However, these devices have a restriction that the width of the bottom plates that form the bottom of the box, that is, the length from the lower edge of the side plate to the butt part of the opposing bottom plates, must be equal.

(Technical Issue) The present invention is intended to solve the above-mentioned problem, and its purpose is to enable design according to the stored items without being restricted by the width of the bottom plate, and to arbitrarily set the position, size, etc. of the partitions. An object of the present invention is to provide a packaging box blank that is easy to manufacture.

(Technical Means) The above purpose is to provide tapered bottom plates 5, 5, 4, and 5 tapered bottom plates at the bottom of the side plates 1, 2, 3, and 4 that form a box by folding cardboard.
6, 7, and 8 are provided so as to be bendable, and the bottom plates 6, 8 on one of the opposing side plates 2, 4 have widths a and b such that c≒a+b with respect to the width c of the other opposing side plates 1, 3. The side plates 2,
The partitions 9 and 10, which are shorter than the length of the partitions 9 and 10, are provided so as to be bendable, and tongue pieces 11 and 12 are cut into the boundaries between the bottom plates 6 and 8 and the partitions 9 and 10, respectively. Engaging portions 14 and 15 are formed between one tongue piece 11 and the other tongue piece 12 so that the other tongue piece 12 can be inserted into the cut-and-raised space 13, and the other bottom plate 5 and 7
sub-partitions 16 having a width reaching each end of the group partitions 9, 10, contacting the group partitions 9, 10 at their tips and fixed thereto at least one end;
17, and the one bottom plate 6, 8 is provided with glue allowances 18, 19 for joining with the bottom plates 5, 7, and the side plates 1, 4 at both ends are similarly provided with glue allowances 20. achieved by.

(Example) Figures 1 to 6 show one example of the packaging box blank according to the present invention. ，
3 and long side plates 2 and 4 are arranged alternately, and tapered bottom plates 5, 6, 7, and 8 are successively arranged below them. In FIG. 1, the thin lines dividing the plate parts 1 to 8 indicate folding lines.

One of the bottom plates 6, 8 connected to the inner long side plates 2, 4 of the two sets of bottom plates 5, 7 or 6, 8 facing each other
Assuming that the width of the other side plates 1 and 3 is c, the widths a and b are determined so that they are equal to the length c when folded and brought together. This width a, b
are not fixed and can be changed freely depending on where and how the partitions 9 and 10 are provided.

The partitions 9 and 10 are provided at appropriate lengths at the tips of the bottom plates 6 and 8, respectively, thereby dividing the inside of the box B into approximately two parts in the longitudinal direction over a desired length. The reason why the partitions 9 and 10 are set to an appropriate length is to provide partitions on both sides with sub-partitions 16 and 17, and each partition 9, 10, 16, 17 is connected to each side plate 1 to 4.
The height is the same as or less than.

The tongue pieces 11, 12 provided at the boundaries between the bottom plates 6, 8 and the partitions 9, 10, that is, the folded line portions,
0 so that they match when aligned, and cut and raise one tongue piece 11 of the other tongue piece 12 into the space 13.
When the tongue piece 12 is engaged with the other tongue piece 12, the protruding engaging part 14 provided at the tip of the other tongue piece 12 engages with the recessed engaging part 15 of the one tongue piece 11, thereby locking the state. .

In the assembled state, the bottom plates 6 and 8 that fix the box body B on both sides are glued together using the glue allowances 18 and 19, and the side plates 1 and 4 at both ends are also glued together using the glue allowance 20 to form the box. Body B is formed. 21 is a glue margin that is glued to the sub-partition 16 and keeps the partition 9 in an upright state;
22 is an extension piece, 23, 24, 25 are notches that facilitate bending of each plate part, 26, 27 are glue allowances 18, 1
Notches corresponding to 9, also 28, 29, 30 and 31
indicates the top plate. Furthermore, a' and b' are the widths of the other bottom plates 5 and 7, which can also be arbitrarily determined in the same manner as described above, and a≠a' and b≠b' may be satisfied.

(Operations and Effects) The packaging box blank of the present invention having the above-described configuration has partitions 9, 10 and sub-partitions 1 inside the assembled box by bending each plate part along the folding line.
6 and 17 can be provided integrally, and in a blank state, it can be bent at the border between the side plates 1 to 4 and the bottom plates 5 to 8 for transportation.

In particular, according to the present invention, when the box is assembled, the bottom plates 6, 8 on one of the opposing side plates 2, 4 have the sum of their widths a, b equal to the width c of the other side plates 1, 3, and hence the width of the box body.
Therefore, there is no design restriction such as a=b, and the positions of the partitions 9 and 10 connected to the tips of the bottom plates 6 and 8 can be freely determined. It is possible, and the group partition 9, 1
0 is fixed by the engaging portions 14 and 15, which has the effect of facilitating the design and manufacture of packaging box blanks.
