Abstract

PURPOSE:To provide an insect-repellent, dissipating the insect-repellent component slowly, and enabling the ready confirmation of the insect-repelling capability, by applying an oil-impermeable patterned layer to a surface of an oil-permeable sheet which turns transparent with oil, and impregnating the obtained substrate with a volatile oily insect-repellent which is liquid at normal temperature. CONSTITUTION:A patterned layer 3 having laminar linear patterns of e.g. a properly colored acrylic resin material is formed on the back surface of an oil- permeable sheet (e.g. paper, nonwoven fabric, etc.) which turns transparent with an oil. A covering material 4 is bonded to the sheet with an adhesive 5 in a manner to cover the surface of the patterned layer 3, and the sheet 2 is impregnated with an oily insect-repellent which is liquid at normal temperature and vaporizes slowly at normal temperature. The surface of the covering material 4 is coated properly with a layer of an adhesive or a pressure-sensitive adhesive 6. The patterned layer developed distinctly at the surface by the impregnation of the oil insert-repellent gradually loses its distinctness according to the dissipation of the agent, and then disappears partly. The insert-repelling capability of the material can be accurately displayed thereby.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an insect repellent material that also functions as an insect repellent indicator.

[Conventional technology]

Recently, in place of the conventional insect repellent materials made by solidifying the volatile solid insect repellent itself into a fixed shape, insect repellent materials consisting of a synthetic resin material containing an insect repellent agent that is volatile at room temperature have been developed. It has come to be widely produced due to its advantages in terms of gender and usability.

[Problem that the invention seeks to solve]

When using such conventional insect repellent materials, there is no change in the constituent materials such as synthetic resins and oranges that determine their appearance, and their insect repellent ability cannot be easily confirmed. The display only displayed the validity period in advance.

The first object of the present invention is to eliminate the drawbacks of conventional insect repellent materials,
The objective of vg20 is to provide an insect repellent indicator that allows the insect repellent ability to be easily and accurately recognized. The fourth object is to obtain a configuration that can stably maintain the insect repellent function, and a fourth object is to provide a period indicator that can be used for a long period of time.

[Means for solving problems]

The present invention achieves these objects, and includes an oil-permeable paper material that is modified to be transparent when containing an oil liquid, and an oil-impermeable pattern layer formed on one side of this paper material as a base material. The present invention is an insect repellent material that also functions as an insect repellent indicator, and is characterized by a structure in which the base material contains a volatile oil-based insect repellent agent that is liquid at room temperature.

In the insect repellent material that also functions as an insect repellent indicator according to the present invention characterized by this structure, the paper-like material functions as a container for the insect repellent agent to be contained, and also serves as a container for the volatile oil-based insect repellent agent contained on the surface. It functions as a volatilization device that volatilizes the agent in a sustained manner, and when made transparent or translucent, it functions as a functional part as a display device. For example, paper material, nonwoven fabric, etc. can be applied. I can do it. Also,
The pattern layer is a display part that flashes through the paper-like material that is made transparent or opaque as described above, and can be formed entirely or partially on the surface of the paper-like material and is made of an oily liquid. For example, oil-impermeable materials that are not altered by insect repellents.
Synthetic resin materials such as polypropylene, latex such as SBR, etc. can be appropriately colored with pigments or dyes and used. For forming this pattern layer, not only a coating method but also general printing methods such as offset printing and gravure printing can be applied. When this printing method is applied, high-speed production is possible in the same way as ordinary printed matter.In addition, the insect repellent to be contained in the paper-like material is liquid at room temperature and volatile at room temperature. Furthermore, it is required to be oil-based so that its volatilization is a sustained release, for example, 0-(2,2-
dichlorovinyl) 0.0-dimethyl phosphate, 4-
Methyl-4-hebuten-1-yn-3-yl-d-cis, trans-chrysanthemate, 2.5,4,5.6-
Pentafluorobenzyl-2,2-dimethyl-3-(2'
, 2'-dichlorovinyl) cyclopropane-1-carboxylate.

〔Example〕

The present invention will be explained in detail below based on embodiments shown in the drawings.

First, the insect repellent material 1 which doubles as an insect repellent indicator according to Example 1 is shown in a plan view in FIG. 1 and in a vertical sectional view taken along line A-A in FIG. 2. 2, and a pattern layer 6 formed on the back surface of the paper-like material 2 in a linear pattern of a suitably colored acrylic resin material.

Further, a cover material 4 is attached to the insect repellent material 1 with an adhesive 5 on the back surface of the paper-like material 2 so as to cover the pattern layer 3 surface. The cover material 4 is made of an oil-impermeable material such as a synthetic resin material such as polypropylene and is formed into a plate or film shape.

Further, on the surface of this cover material 4, an adhesive or adhesive 6 is applied in a layered manner.

This insect repellent material 1 further contains the above-mentioned insect repellent agent in 2 portions of the paper-like material.

- In addition, for the inclusion of this insect repellent agent, a general inclusion or injection method such as a dipping method can be applied to the paper-like material.

In the insect repellent material 1 constructed as described above, the paper material 2 may be not only Western paper but also Japanese paper, and even paperboard as long as it exhibits the same function.

This paper material generally has a layered structure in which fibers of various shapes and sizes are intricately intertwined, and its structure is porous. Therefore, when the above-mentioned oil-liquid insect repellent agent is contained, it is retained in this porous portion. Therefore, the paper material containing the insect repellent, that is, the paper-like material 2, becomes partially or completely transparent.

This can be easily confirmed in FIG. In other words, if the insect repellent 7 is not contained in the paper material 2', the paper material 2' appears opaque as a whole because the incident light a' on its surface only causes reflected light C'. , when the insect repellent 7 is contained, the incident light a on the surface of the insect repellent 7 in the form of an oily liquid held in the porous portion generates refracted light that reaches the pattern layer 3, and the reflected light C is As a result, the paper material 2' becomes transparent and the pattern layer 3 becomes visible. This action functions as an indicator, which is also performed by volatilization of the insect repellent from the two surfaces of the paper-like material. In addition, the volatilization of the insect repellent agent at this time produces an insect repellent function.

The function of displaying the insect repellent ability or period and the function as an insect repellent in the insect repellent material 1 described above are as follows: It is demonstrated in exactly the same way. In addition, Example 3 shown in FIG.
A pattern layer 3' covering the back side of the paper-like material 2 as shown in FIG.
, this pattern @S/ limits the volatilization of the insect repellent from the paper-like material 2 only from its surface. In addition, in the present invention, as in Example 4 shown in FIG. You can also.

In this case, the functions described above are equally exhibited on both sides of the insect repellent material 1''.

Insect repellents 1' to 1' of Examples 2 to 4 are designed to include ventilation parts to prevent the insect repellent contained therein from adhering to other objects and to make it easier to use. It is packaged with a transparent packaging material or stored in a storage section 11 of a transparent storage case 10 as shown in FIG. In addition, 12 is a radiation hole communicating with the storage part 11, and 13 is a hanging part.

The above is exactly the same even when the paper-like material 2 is, for example, a relatively thin non-woven fabric, but due to the inherent strength and elasticity of the non-woven fabric, a relatively large amount of insect repellent can be contained. This makes it possible to quantify the content. It is possible to use the product as an insect repellent or an indicator for a longer period of time, and it is also possible to further equalize the period of use of the product.

In addition, in the insect repellent material 1 in Example 1, the cover material 4
prevents the volatilization of the insect repellent contained therein toward the back surface of the paper-like material 2 and restricts it to only toward the surface thereof, and also prevents the volatilization of the contained insect repellent agent from being carried out toward the back surface of the paper-like material 2.
It also functions as a substrate when being fixed to other objects via.

As shown in FIG. 8, for example, the insect repellent material 1 has a structure in which the insect repellent material 1 is pasted on the surface of a storage case 160 in which the aromatic substance 15 is stored or on the surface of the recessed part 17 formed on the surface. and use it. In this case, although the original insect repellent function of the insect repellent material 1 can be mainly exhibited, it is also possible to use its indicator function mainly as a period indicator for the aromatic substance 15.

[Configuration example]

A white paper (0.1 m+thickness) was used as the paper-like material, and SBR colored red with a pigment was applied onto one side of the white paper to form a pattern layer to form a base material.

This base material was cut into a rectangular shape of lam × 3 cm, and the cut pieces were impregnated with 50 coats of 0-(2,2-dichlorovinyl)0°O-dimethyl phosphate to form a pattern layer on the surface. An insect repellent material that doubles as an insect repellent indicator and that appears brightly was obtained.

As a result of using this insect repellent material that doubles as an insect repellent indicator in the shade from winter to summer, the pattern partially disappears after about 5 months, and completely disappears after about 6 months. It turned into a white surface.

It also exhibited an effective insect repellent effect within this period.

〔Effect of the invention〕

In the present invention, the paper-like material is denatured to be transparent or opaque depending on the presence or absence of the insect repellent, and the pattern on the back surface appears or disappears, so that it functions as an indicator. Since the function is exhibited depending on the amount of insect repellent contained in the paper-like material, it has the effect of displaying its insect repellent ability extremely accurately.・In addition, the display effect can be maintained for a long period of six months or more, and therefore, it can be used in a variety of ways as a period indicator.

Further, in this case, the contained insect repellent is directly volatilized from the paper-like material, and a sufficient insect repellent effect can be obtained at any time as an insect repellent. Moreover, its structure is extremely simple and it can be manufactured at low cost.
