Description

The present invention relates to an insect repellent material, and more particularly to an insect repellent material in which an insect repellent is applied as a pattern to an insect repellent target area of the insect repellent material.

Cockroaches, mites, etc. are sanitary pests that transmit viruses that cause diseases to humans, and food-related stores (for example, food stores such as supermarkets and department stores, fresh fish stores, butcher shops, and specialty retail stores such as fruit and vegetable stores. ) Is known as a food pest that harms food, and a great deal of effort is required to remove it.

Organophosphorus, carbamate, and pyrethroid insecticides that have been conventionally used for controlling sanitary pests have been used for a long time because they have excellent insecticidal activity and are inexpensive.

However, when the pests that have appeared are slaughtered with an insecticide, etc., if they are not removed immediately, the dead pests will remain on the spot, which may cause discomfort to the purchaser. , With pest repellents, emphasis is placed on methods of repelling pests.

In order to obtain a continuous pest repellent effect, it is known that a porous substance or the like is impregnated with a pest repellent to repel pests (Patent Document 1).

In addition, in order to maintain the pest repellent effect and reduce the effect on the human body during handling, it is composed of a resin film / repellent layer / printing layer / adhesive layer / paper base material in order from the surface, and the resin film on the surface. A laminated body having a pest repellent effect provided with fine pores serving as repellent volatilization pores is known (Patent Document 2).

However, even when it is desired to obtain a pest repellent effect for a relatively short period of time, it is wasteful to apply the pest repellent to the entire surface of the insect repellent area, and as in Patent Document 1, a porous substance is used. The method of impregnating is good for obtaining a repellent effect for a long period of time, but it is too complicated to easily obtain a repellent effect.

Further, the invention of Patent Document 2 emphasizes continuity, is complicated in an insect repellent seal or the like, and controls evaporation of a repellent by fine pores of a resin film, so that it has a quick effect. There is a problem of scarcity.

In addition, in the conventional insect repellent material, the part to which the pest repellent is applied has a repellent effect, and although it is known that characters and patterns are drawn with ink or paint containing the pest repellent. In each case, the repellent effect is obtained for the drawn area.

That is, it can be said that it is not intended at all to obtain the repellent effect in a region wider than the coating region while reducing the coating area of the pest repellent.

An object of the present invention is to provide an insect repellent material which can obtain the same repellent effect as when it is applied to the entire surface while reducing the application area of the pest repellent.

That is, the present invention is an insect repellent material coated with a pest repellent.
A base sheet having a surface including an insect repellent area and
A pest repellent applied as a pattern to the insect repellent target area of the insect repellent material on the surface, and the like.
The insect repellent material is characterized in that the total area of the pattern is 60% or less of the area of the insect repellent target area.

Further, the present invention is characterized in that the pattern of the insect repellent material is one selected from dots, checkered patterns, borders, lattices and concentric angles.

The present invention is also characterized in that the insect repellent material is an insect repellent label, an insect repellent food bag, or an insect repellent seal.

The present invention is also characterized in that the pest repellent is copaiba oil.

According to the present invention, since the application area of the pest repellent is 60% or less of the application target area, the waste of the repellent can be eliminated and the cost can be reduced.

According to the present invention, since the application area of the pest repellent is 60% or less of the application target area, the cost of the pest repellent can be reduced when used in a short period of time, which is convenient. Further, by increasing the concentration of the pest repellent when applied, the repellent effect for a long period of time can be maintained, and the cost can be reduced as compared with the case where the pest repellent is applied to the entire surface.

Further, according to the present invention, since the repellent is applied as a pattern, it is convenient to use a colorant or the like in combination for coloring because the aesthetic appearance is excellent and the applied portion can be visually recognized.
