Is also used.

By the way, the raw material for corrugated board is wood (pulp). Therefore, when cardboard is used in a place where termites or the like live, or where there is a possibility of that, it is necessary to give sufficient consideration to food damage caused by termites, regardless of the purpose of use.

For this reason, when corrugated board is used as a material for construction and civil engineering, termites have been sprayed on and around the passages of termites (hereinafter referred to as ant trails) (Japanese Patent Laid-Open No. 58-142927). Japanese Patent Laid-Open No. 58-36139
(See the official gazette). Further, when cardboard is used as a packaging material, an anti-termite agent or the like is put in the cardboard box.

[0005]

However, the termites and the like that could reach the cardboard due to some factors by simply spraying the ant-repellent agent on and around the ant road, use the cardboard itself as a temporary nest, and There is a risk that the nest will spread all over and suffer great damage.

Further, when an ant-preventive agent or the like is put into a cardboard box, it is necessary to take care that the contents stored in the cardboard box do not come into contact with the ant-preventive agent, etc. There was also the problem of taking this.

The present invention has been made based on such a situation, and is subjected to an anti-termite treatment which can prevent damage by termites and can be used not only as a packaging material but also as a construction or civil engineering material. The purpose is to provide corrugated cardboard.

[0008]

In order to achieve this object, the invention according to claim 1 provides at least one corrugated cardboard obtained by laminating a flat paperboard on at least one side of a corrugated corrugated core paper. An anti-termite agent is attached to the entire surface of the paperboard.

According to a second aspect of the present invention, in a corrugated board in which a flat paperboard is attached to at least one surface of a corrugated corrugated core paper, at least one of the paperboards is impregnated with an anti-termite agent. It is characterized by that.

The invention according to claim 3 is characterized in that the core paper is impregnated with the ant-preventive agent.

Further, the invention according to claim 4 is characterized in that the termiticide contains imidacloprid as an active ingredient.

[0012]

According to the first aspect of the present invention, the ant-preventive agent is attached to the entire surface of at least one paperboard to be bonded to at least one surface of the corrugated fiberboard. Therefore, when the corrugated board according to the present invention is used as a material for construction and civil engineering, by providing an anti-termite agent layer over the entire surface of all paperboards, the corrugated board itself functions as a multiple termite-proof fence and termites are used. It will divide the ant road such as, and can prevent feeding damage by termites. Further, when the corrugated board according to the present invention is used as a packaging material, the contents to be stored in the corrugated cardboard box can be improved by attaching an anti-termite agent over the entire surface of only the paperboard located on the outer surface side of the corrugated board box. Since it does not come into contact with the ant-preventive agent, it is possible to save the trouble of handling at the time of packaging.

According to the second aspect of the present invention, at least one paperboard to be bonded to the core paper is impregnated with the termite proofing agent. Therefore, even if a termite or the like eats a part of the corrugated cardboard, the termite or the like will be killed, and the range of feeding damage can be suppressed.

According to the third aspect of the invention, since the core paper is also impregnated with the termite-preventing agent, termites and the like cause a gap between the corrugated core paper and the two paperboards. It is possible to avoid the behavior that makes it an ant path.

Further, according to the invention of claim 4, the termite control agent contains imidacloprid as an active ingredient,
Since this imidacloprid has a long-term insecticidal effect and high safety, it can provide effective ant control.
