Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to an indicator of the volatilization process that allows the volatilization process and its end point to be identified very clearly.

"Conventional technology" In recent years, with the desire for a more comfortable life, we have devised ways to gradually release ingredients such as fragrances and drugs for use in furniture, toilets, rooms, cars, etc. so that their effects can last for a long time. A number of constructs have been developed.

Such structures include: (1) one in which the above component is adsorbed on a porous substance, (2) one in which the above component is encapsulated in microcapsules, (2) the above component or (2) or (4) in a gel material, resin, wax or sublimable material. Things contained in substances, ■
The above ingredients or ■ or ■ or ■ are coated or impregnated on cloth, paper, or film; ■ The above ingredients or ■ or ■ or ■ or ■ are further applied to ceramic, glass, or synthetic resin containers, films, paper, or cloth It is known to be placed in a bag.

An indicator indicating the effectiveness of such a composition has been devised to indicate the release status of the components of such a sustained release agent.

Conventionally, the following devices have been used as indicators of the progress of volatilization.

(a) A dye that uses a vaporizable (sublimable) dye and takes advantage of the reduction in the degree of coloring caused by its vaporization.

(b) A combination of an electron-donating color former, an electron-accepting color developer, and a volatile or sublimable desensitizing component, and the color is developed by volatilization of the desensitizing component.

(C) Colored pigments or colored dyes are mixed with the ingredients in (a) or above.

However, all of these products gradually become colored, faded, or discolored as the ingredients are released, and the sensitivity to discoloration is extremely poor.Therefore, the end point of the effect that indicates that the product has been used tends to be unclear. Even if the stored ingredients are almost completely gone and they are no longer effective, they are left unused for a long time without being replaced with new ones, or conversely, they still have a lot of active ingredients left and can still be used. It has the disadvantage that it is often discarded.

"Problems to be Solved by the Invention" The present inventor has solved the process of volatilization of stored components and its end point by allowing a specific container to hold a substance that colors, discolors, or changes color as the stored components volatilize. The object of this invention is to provide a display body that can be identified very clearly.

"Means for Solving the Problems" The display body of the present invention contains a substance that colors, discolors, or changes color in correlation with the volatilization of stored components in a storage body that has a part that is permeable to volatile components. It is characterized by the fact that it has been forced.

To explain the above structure in more detail, first, a storage body with a permeable part is a storage body that has a permeable part so that the stored components can volatilize and permeate. Not limited to. The transmission part is open or made of porous materials such as paper, cloth, nonwoven fabric, porous synthetic resin, or porous glass, and the storage body itself is made of synthetic resin, glass, ceramics, metal, wood, etc. It is desirable that the side walls of the container be completely or partially transparent or semi-transparent so that it is easy to see through clearly the state of coloring, decoloring, or discoloration as the stored components volatilize. The shape of the storage body can be made into various shapes depending on the purpose, such as a cylindrical shape, a rectangular tube shape, a rod shape, a plate shape, and a sheet shape.

With the above configuration, coloring occurs as the stored ingredients volatilize.
Examples of color erasing or color changing substances include (a) electron-donating color formers, (a) electron-accepting color developers, and (C

The display of the present invention is stored in a sealed state until it is used, and various methods can be used to seal it, such as closing the permeable area with a lid or a sealing film.

In addition, the substance used in the display body of the present invention, which colors, discolors, or changes color with the volatilization of the stored component, may be retained in any part of the housing, but it may not be retained only near the transparent part. , which is less desirable because the change tends to occur suddenly and it is difficult to display it for a long time.

Example 1 As shown in Fig. 1, menthone (fragrance) having an effective period of about two weeks was slowly placed in one chamber of a cylindrical polystyrene container with an inner diameter of 2 cm and a depth of 5 cm, which was divided into two chambers by a partition wall. It was stored as an open body, and 30 parts of m-methoxyphenol, 5 parts of crystal violet lactone, and a yellow dye (trade name: Kayaset) were placed on the entire inner wall of the other chamber of the container.
A composition prepared by dissolving 5 parts of Yellow 077J (manufactured by Nippon Kayaku ■) was coated to a thickness of 1 cm to form a display section, which served as a display for the progress of volatilization.

The display body gradually yellows from the top to the bottom as the sustained release body releases its odor, and the yellowing to the bottom is completed in 15 days, almost coinciding with the expiration point of the sustained release body. As a result, the remaining efficacy of the sustained release material can be easily determined by checking the yellowing position of the display section, and by using it in correlation with the volatilization progress of the stored ingredients, it functions effectively as an indicator of the volatilization progress. It was confirmed that

Example 2 A composition prepared by mixing 20 parts of light calcium carbonate with a solution of 50 parts of menthone (fragrance), 2 parts of crystal violet lactone, and 4 parts of phenol resin was mixed with an inner diameter of 2 parts.
cs, was applied to the entire inner wall of a cylindrical glass container with a depth of 5 cm to a thickness of 1 mm to provide an indicator of the progress of volatilization.

The indicator gradually turns blue from the top to the bottom along with the gradual scent of mentone, which is a sustained release agent, and the blue change to the bottom is completed in 7 days, which is almost the same as the time when the sustained release agent expires. I had lost once. Incidentally, as a result of analysis by gas chromatography, it was confirmed that the residual rate of menthone at the time of completion of blue coloring was 1% or less. As a result, the remaining efficacy of the sustained release agent can be easily determined by checking the yellowing position on the display, and by correlating with the volatilization progress of the contained ingredients,
It was confirmed that it functions effectively as an indicator of the progress of volatilization.

Example 3 As shown in Fig. 1, a cylindrical polystyrene container with an inner diameter of 2cI1) and a depth of 5cflI was divided into two chambers by a partition wall, and one chamber was filled with menthone (with an efficacy period of about 2 weeks).
A composition prepared by melting 30 parts of m-methoxyphenol and 5 parts of crystal violet lactone was placed on the entire inner wall of one chamber of the container to a thickness of 1 w. It was coated to form a display section to display the progress of volatilization.

The display body is colored blue, and the color gradually fades from the top to the bottom as the sustained-release body releases its fragrance. Discoloration to the bottom is completed in 15 days, and the gradual-release body releases its fragrance. This almost coincides with the expiration point, and as a result, it is easy to check the remaining efficacy of the sustained-release agent by checking the discoloration position on the display, and by using it in correlation with the volatilization process of the stored ingredients, It was confirmed that it functions effectively as a display body.

"Effect" According to the volatilization progress indicator of the present invention, the volatilization progress of volatile components such as perfumes and medicines stored in the container can be clearly identified, so the end point of the effect can be reliably grasped. This excellent effect can be obtained.
