Description

[Detailed description of the invention] (1) Industrial application field This invention relates to a cardboard box with marks for inspecting printing misalignment.

(2) Problems to be solved by conventional techniques and ideas A cardboard box for storing can products such as beer cans and cider cans is made up of, for example, a top plate, a bottom plate, left and right side plates, front and rear side plates, and an inner flap. There are some that can be formed into a box shape by folding along folding lines provided at the continuous portion.

By the way, when the cardboard box is manufactured, the product name, brand, etc. are usually printed on its outer surface and die cut is performed, but printing misalignment may occur during the die cutting.

Conventionally, there has been no apparatus for accurately inspecting such printing misalignment, and there has been a problem in that inspections tend to be neglected, resulting in defective cardboard boxes being delivered and used as is.

In view of the above-mentioned conventional problems, the object of this invention is to provide a corrugated cardboard box that can be easily inspected for printing misalignment that occurs during die cutting, and that can reliably eliminate the delivery of defective corrugated cardboard boxes.

(3) Means for solving the problem In order to achieve the above object, when the cardboard box of this invention is formed into a box shape, a part other than the inner flap is attached to the tip corner of the inner flap on the outer surface side. It is characterized in that a mark printed on the outer surface for inspecting printing misalignment in the vertical or horizontal direction of the printed part is printed at the same time as the printing of the printed part.

(4) Example In Figures 1 and 2, 1 indicates a cardboard box,
2 is a top plate; 3 is a bottom plate; 4 and 5 are left and right side plates that are bendably connected to one side edge of the top plate 2, the other side edge of the bottom plate 3, and one side edge of the bottom plate 3; 6, 7, 8; Reference numeral 9 refers to front and rear side plates that are bendably connected to the front and rear edges of the top plate 2 and the bottom plate 3, and 11, 12, 13, and 14 connect the left and right side plates 4 and 5 to the folding lines of the front and rear side plates 6, 7, 8, and 9. The inner flap 16 is connected to the left side plate 5 so as to be bendable along the extension line.

In the drawing, each dotted line indicates a folding line, and using these folding lines, the first
It is now possible to form it into the box shape shown in the figure. In addition, the top plate 2, the left and right side plates 4, 5, the front and rear side plates 6, 7,
The part surrounded by thin lines on the outer surface of 8 and 9 indicates the printed part A on which the product name, brand, etc. are printed.

At the tip corner of the inner flap 11 on the outer surface side, there is a mark 18 of 1 to 3 mm, for example, for visually or electrically inspecting whether or not the printed portion A is misaligned in the vertical or horizontal direction. Width X, printing section A
is being printed at the same time as printing.

In the embodiment described above, if printing misalignment occurs in the printing part A during die cutting, the mark 18 printed at the same time
The mark 18 may not be printed properly as shown in Figure 3, and the width X of the mark 18 may become narrower or different in the vertical or horizontal direction, or in extreme cases, the mark 18 may be printed incorrectly. It will be in a state where it will not be done.

Therefore, after stacking a large number of cardboard boxes 1 with the printed portion A printed on the outer surface in an unfolded state with the printed portion A facing upward, the inner flaps 11 are manually inspected to visually check the mark 18, or By inspecting using a method based on the method, it becomes possible to easily inspect the printing misalignment of each cardboard box 1, one by one.

FIG. 4 shows another embodiment of this invention, in which a mark 20 of a color corresponding to the second color, for example, is printed adjacent to the mark 18 at the same time when the printing part A is multi-color printing. be.

The shapes of the marks 18 and 20 described above are merely examples, and other shapes may be used as long as the printing deviation in the vertical direction or the horizontal direction in the printing section A can be inspected. Furthermore, the portions on which the marks 18 and 20 are printed are not limited to the inner flap 11, but may be printed on other inner flaps. Furthermore, although the cardboard box 1 has the structure shown in the figure, it is not necessarily limited to this structure.
For example, it goes without saying that a cardboard box without a top plate and a top surface may also be used.

(5) Effects of the device Since this device is configured as described above, by inspecting the mark on the inner flap, it is possible to detect the vertical or horizontal direction that occurs when cutting out the printed part printed on the outer surface other than the inner flap. Printing misalignment can be inspected extremely easily, and delivery of defective cardboard boxes can be reliably avoided. Furthermore, since the mark is printed on the inner flap and is formed into a box shape, it becomes a hidden part, which has the excellent effect of not looking unsightly.
