Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a cardboard box for packaging in which a corrugated cardboard step is exposed on the outer surface of the cardboard box.

[0002]

[Prior art]

 Conventionally, packaging cardboard boxes are often made of so-called double-faced cardboard in which a step is provided between two liners. Since such a cardboard box is inferior in design as it is, the cardboard box may be decorated by printing characters or patterns on the surface of the cardboard box or attaching a cosmetic film. However, the improvement of the designability by such a method causes an increase in cost.

Therefore, the inventors of the present invention, after repeated trial and error, use a single-sided corrugated board in which a step is attached to one side of a liner, and manufacture a corrugated board box so that the step is exposed to the outside. Then, I realized that a corrugated cardboard box with a high degree of interest could be obtained without the need to separately decorate the cardboard due to the pattern formed by the unevenness of the steps.

[0004]

[Problems to be solved by the device]

 However, it is somewhat difficult to attach a display means, such as for indicating the contents of the box, to the outer surface of the cardboard box in which the single-sided corrugated board is exposed on the outer surface.

That is, even if the display means is attached to the uneven surface having the step by printing, stamping, etc., the characters and / or patterns are cut off, and the display means cannot be an effective display means. Even if an attempt is made to attach a display means consisting of the above, the unevenness of the display means may hinder the stable attachment state and facilitate the peeling. In addition, when characters are printed on a sheet-shaped core paper and then the core paper is formed into a corrugated shape, the display means also becomes corrugated. , It did not become an effective display method.

The present invention has been made in view of the above problems, and the display means can be easily and effectively maintained while maintaining the interest of the pattern formed by the unevenness of the steps exposed on the outer surface of the cardboard box. It is an object to provide a cardboard box for packaging that can be attached to the.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a packaging cardboard box according to the present invention comprises a single-sided corrugated cardboard box, wherein the corrugated cardboard box for packaging is produced by exposing the corrugated corrugated board of the single-sided corrugated board to the outer surface. At least a part of the box is a double wall composed of inner and outer walls arranged so that the liners face each other or are in contact with each other, and the outer wall is provided with a window hole facing the liner of the inner wall. It is characterized in that display means is additionally provided at a position corresponding to the window hole.

By adopting the above configuration, while maintaining the interest of the pattern formed by the unevenness of the steps exposed on the outer surface of the cardboard box, the liner on the inner wall is passed through the window hole provided on the outer wall. It may be possible to reliably recognize the display means attached above. Further, since the display means is also attached to the flat liner having no unevenness, it can be easily and surely performed.
