Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indicator / combined drug / solution volatilizer used for volatilization of a drug / liquid agent, and more particularly to a display / combined drug / solution volatilizer having improved display of the remaining amount of the contained drug / liquid agent.

[0002]

2. Description of the Related Art In recent years, an insect repellent material having a synthetic resin material containing an insect repellent liquid agent that is volatile at room temperature has been used in place of the insect repellent material obtained by solidifying the volatile solid repellent agent itself as it is. It has become popular because of its advantages in terms of sex and usability.

Insect repellents containing such an insect repellent liquid agent in a synthetic resin material are different from those using the volatile solid insect repellent itself, and therefore the insect repellent ability of the insect repellent liquid agent cannot be confirmed by the size of the insect repellent material. , Various kinds of devices provided with means for displaying insecticidal ability have been developed.

As an example thereof, there is provided a paper-like material composed of an oil-liquid permeable substrate material exhibiting a base color and an oil-permeable, low refractive index ground color layer formed on one surface of the substrate material, A gas-impermeable or gas-semipermeable transparent or translucent cover material is laminated on the ground color layer surface of the paper-like material to form a paper-like body, and the paper-like portion of the paper-like body is vaporized at room temperature. A mosquito repellent material that also serves as a mosquito repellent indicator has been developed (see JP-B-4-36123).

In this insect repellent material which also serves as an insect repellent indicator,
In the state where the liquid chemical has penetrated into the paper-like body, the ground color layer is made transparent due to the low refractive index, and the base color on one surface of the substrate material can be confirmed through the cover material. When the liquid medicine is completely discharged from the paper-like body, the background color layer becomes opaque, and the color of the background color layer can be confirmed through the cover material. The change in color tone in such a paper-like body depends only on the residual amount of the chemical solution from the substrate material, and does not depend on the presence of the vaporized gas of the insect repellent liquid agent, and therefore the point of change in the color tone of the contained insect repellent liquid agent is Consistent with the vanishing point, its display function is extremely accurate.

However, in the insect repellent material which also serves as an insect repellent indicator, since the indication has two stages, that is, the state in which the contained insect repellent liquid agent remains and the state in which it completely disappears, it is used for insect repellent of clothes in general households. In many cases, the insect repellent material that also serves as the insect repellent indicator was replaced with a new one after the contained insect repellent liquid agent had completely disappeared.

[0007]

In such a conventional insect repellent display / insect repellent material as described above, the indication has two stages, that is, the state in which the contained insect repellent liquid agent remains and the state in which it is completely disappeared, so that it can be worn at home. In the case of using for insect repellent, the insect repellent indicator and the insect repellent material should be replaced with a new one only after the contained insect repellent liquid agent has completely disappeared, and in many cases insect repellent cannot be performed during this period.

Therefore, the present invention has three levels of the remaining amount of the contained liquid chemical agent, that is, a state in which the contained chemical liquid agent remains in a larger amount than a predetermined amount, a state in which the contained liquid chemical agent remains in a predetermined amount or less, and a completely disappeared state. It is an object of the present invention to provide a chemical liquid agent volatilization device which can also be used as an indicator.

[0009]

According to the structure of claim 1, the first color can be confirmed in the entire sheet material when the contained chemical liquid remains in an amount larger than a predetermined amount. When the remaining amount is less than the predetermined amount, the first color can be confirmed only in the portion corresponding to the pattern forming portion of the sheet material, and the remaining sheet material portion has the second color because the liquid chemical has disappeared. Then, in the state where the contained liquid chemical has completely disappeared, the liquid chemical has disappeared over the entire surface of the sheet material, and the second color is confirmed.

According to the second aspect of the present invention, in the state where the contained chemical liquid is larger than the predetermined amount, the first color can be confirmed in the entire sheet material, and the contained chemical liquid remains below the predetermined amount. If it is, the first color can be confirmed in the part of the sheet material excluding the pattern forming part, the chemical liquid disappears in the pattern forming part and the second color is confirmed, and the contained chemical liquid is completely disappeared. Then, the liquid chemical disappears over the entire surface of the sheet material, and the second color is confirmed.

According to the structures of claims 3 to 6, when the amount of the contained chemical liquid remains in excess of a predetermined amount, the entire surface of the refractive index changing layer has a relatively low refractive index and becomes transparent, so that the substrate material When the first color can be confirmed on the entire surface on which the refractive index changing layer is formed, and the contained chemical liquid remains in a predetermined amount or less, the pattern forming portion of the refractive index changing layer or a portion other than the pattern forming portion Since only one of them remains low in refractive index, it remains transparent, and the first color of the substrate material can be confirmed only in the pattern forming portion of the refractive index changing layer or the portion other than the pattern forming portion,
The remaining part of the refractive index changing layer has a high folding rate and becomes opaque, and the second color, which is the background color, is confirmed. When the contained chemical liquid is completely disappeared, the entire surface of the refractive index changing layer has a relatively high refractive index. And becomes opaque, and the second color, which is the background color, is confirmed.

According to the structure of the tenth aspect, the first color of the chemical liquid agent can be confirmed in the entire substrate material in the state where the chemical liquid agent content is larger than the predetermined amount, and the chemical liquid agent content is the predetermined amount. If only the following amount remains, the first color of the chemical solution can be confirmed only in one of the pattern-formed portion of the substrate material or the portion other than the pattern-formed portion, and the chemical liquid agent disappears in the remaining substrate material portion to the first color. In the state where the color of 2 is confirmed and the contained drug solution has completely disappeared,
The second color is confirmed by disappearance of the liquid chemical on the entire surface of the substrate material.
