Abstract

(57) [Abstract] [Purpose] To provide a high-grade paperboard for paperboard which is easy to manufacture, has a constant quality, and is easy to provide a pattern on the surface. [Structure] By coating a thermoplastic adhesive on the paperboard layer 1, printing a foam ink on it, printing a pattern ink on it, and then applying heat to the whole to foam the foam ink. The paperboard layer 1, the heat-bonding layer 2, the foaming ink layer 3 and the pattern 4 are laminated in this order. Due to the foamed ink layer 3 having a roughened surface, a paperboard for paperboard having a high-quality feeling completely different from ordinary paperboard can be obtained.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a paperboard for paper containers used for gift boxes and the like.

[0002]

[Prior Art]

 BACKGROUND ART Conventionally, as a paperboard for a paper container used for a gift box or the like, a paperboard that has been variously modified on its surface to give a high-grade feeling is used. For example, there are those with decorative cloth attached and those with decoration by electrostatic flocking.

[0003]

[Problems to be solved by the device]

 The former paperboard among those described in the prior art is excellent in texture, but has drawbacks such as complicated manufacturing process and many variations in quality. Although the latter paperboard has stable quality, it also has the drawback that it is time-consuming and costly to manufacture. Furthermore, both had the drawback that it was difficult to apply a pattern to the surface.

The present invention was devised to eliminate the above-mentioned drawbacks of the conventional ones, and is a high-class product that can be easily manufactured and has a constant quality and that it is easy to provide a pattern on the surface. The purpose of the present invention is to provide a paperboard for paper with a feeling.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the paperboard for paperboard of the present invention is characterized in that a paperboard layer, a thermal adhesive layer, a foaming ink layer and a pattern are laminated in this order.

[0006]

[Action]

 The paperboard board having the above-described structure has a texture with a high quality feeling, which is completely different from that of ordinary paperboard due to the roughened foam ink layer.

[0007]

【Example】

 FIG. 1 is a sectional view showing an embodiment of a paperboard for paper container according to the present invention. In the figure, reference numeral 1 denotes a paperboard layer made of paperboard used for a normal paper container, on which a foam ink layer 3 is laminated via a heat-bonding layer 2, and further a pattern 4 is applied on the foam ink layer 3. There is.

In this paperboard for paper containers, a thermoplastic adhesive made of an acrylic resin is coated on the paper layer 1, and a polyvinyl chloride-based heat-foaming ink having a thickness of 5 to 10 μ is solidly coated thereon. It is manufactured by printing, printing the desired pattern (including characters) with a polyvinyl chloride-based or acrylic-based pattern ink, and then applying heat to the whole. It is desirable that the foaming ink has a foaming ratio of 2 to 10 times. In this way, the foamed ink is foamed by applying heat to form the foamed ink layer 3 having a rough surface. In addition, the foamed ink layer 3 itself is rich in flexibility and excellent in abrasion resistance.

As another form, the foamed ink layer 3 in the portion where the pattern 4 is provided may be omitted.

The paperboard board having the above structure is used to form a paperboard, such as a gift box lid or a single whiskey box, which is desired to have a high-grade feeling. Then, the assembled paper container has a high-grade feeling due to the roughened foam ink layer 3, and a desired pattern is appropriately arranged.

[0011]

[Effect of the device]

 As described above, the paperboard board of the present invention has a structure in which a foamed ink layer is laminated on a normal paperboard to give a high-class feeling, so that cloth can be pasted or flocked as in the past. It is possible to manufacture products of consistent quality by a simple process of printing foaming ink and foaming it, as compared with the case of using the same. Further, the design can be easily provided by printing at the same time.
