Description

[Detailed explanation of the idea]

The present invention relates to an aromatic body made of a composite fragrance that does not change its scent tone over time and always emits a constant aroma. Unlike perfumes, which are used only based on personal preference, aromatic substances used in general homes and automobiles can be used universally in places with different odors such as the living room, kitchen, toilet, and inside of automobiles. It is designed to mix individual fragrances to produce a scent that is liked by many people. However, each fragrance has its own unique vapor pressure. For example, in the case of two types of compound fragrance, one with a high vapor pressure and one with a small vapor pressure at room temperature.
When the seeds are in the form of a liquid, which is a conventional mixture of two types of fragrances dissolved in a solvent, or solids, which are impregnated into a suitable carrier at the same time, they have a large vapor pressure. The substances volatilize first, and after a certain period of time, there is almost no residue left of those with high vapor pressure, only those with low vapor pressure, and the fragrance tone and amount are different at the beginning and end. In addition, glycols and the like are sometimes used as fragrance retention agents, but by dissolving fragrances with a high vapor pressure into the retention agent, it is possible to suppress rapid volatilization and extend the fragrance release time. Although it is effective in the sense of controlling the fragrance amount to a constant level at all times for single fragrances, it is effective in controlling the fragrance amount to a constant level over time, which is the purpose of this invention, for several types of compound fragrances. It is not sufficient in terms of emitting aroma. The inventors of the present invention conducted various studies on how to maintain a constant fragrance tone over time without changing the fragrance tone of a composite fragrance consisting of several types of fragrances with different vapor pressures. The objective was achieved and the present invention was completed by dividing the vapor pressure into different amounts depending on the vapor pressure, and making it more difficult to volatilize as the vapor pressure increases. The present invention will be explained using figures. Figure 1 shows an example of the composite fragrance aromatic product of the present invention. If three types of fragrances with different vapor pressures are used, the carriers are impregnated with the fragrances separately according to the order of the vapor pressure from high to low. That is, the impregnated bodies are provided at appropriate intervals such as 1, 2, and 3 from bottom to top. In other words, the higher the vapor pressure, the more difficult it is to volatilize. 6 is a support supporting the impregnated body at each stage. Then, several holes 4 are bored in the impregnated body 2 immediately above the lowermost impregnated body 1 to serve as a passage for the fragrance volatilized from the lowermost impregnated body 1. Furthermore, a hole 5 is also bored in the uppermost impregnated body 3, but this is because the fragrance in the middle impregnated body 2 has a lower vapor pressure than the fragrance in the lowermost impregnated body 1, and because it is a common passage with the fragrance from the lowermost impregnated body 1. In order to
It is necessary to increase the pore diameter or the number of pores. The pore diameter and number of pores vary depending on the relative relationship of vapor pressure of each fragrance used, and cannot be determined unconditionally, but approximately 2
~15mmφ (varies depending on the area of the impregnated body). For example, a three-tiered impregnated body with an incense outlet 8 at the top as shown in the figure.
If it is stored in a container 7 with a shape, it becomes a composite fragrance aromatic body. As an example, the present invention has been described in the case of three stages, but if there are more types of fragrances, the number of stages of the impregnated body may be increased accordingly, and there is no problem in providing any number of stages. Further, even if the types of fragrances are different, there is no problem even if the same carrier is impregnated with any number of fragrances as long as there is almost no difference in vapor pressure. Here, the impregnated body is a carrier into which the fragrance is impregnated, so any material that does not react with the fragrance or change the quality of the fragrance, such as porous plastic, paper, and unglazed pottery into which the fragrance permeates, may be used, and there are no particular restrictions. There isn't. Furthermore, it is also possible to use a plastic molded article as a carrier, mix a fragrance in advance at the time of molding, and mold it into a suitable shape to obtain an impregnated body. In this case, fragrances that mostly volatilize or thermally decompose at the temperature during molding cannot be used. In addition to the circular shape shown in FIG. 1, the shape can be arbitrarily selected such as a circular shape or a polygonal shape. Furthermore, the size of the impregnated body can be increased toward the bottom, and can be used instead of the holes described above. Next, the present invention will be explained in more detail with reference to Examples. Examples, Comparative Example 1 Three types of fragrances are ranked in order of ease of volatilization: top notes (e.g. boiling point below 200°C), middle notes (e.g. boiling point 200-240°C) and end notes (e.g. boiling point
240° C. or above), and the carrier was impregnated with each fragrance from the lower stage as shown in Fig. 1, and then stored in a container and volatilized. In this case, the amount of fragrance was about 10 g in all cases, the carrier was 50 mm in diameter, and several 5 mm in diameter holes were made in the upper stage and several 3 mm in diameter in the middle stage. On the other hand, a three-stage carrier having the same dimensions as in the example was impregnated with a mixture of the same three fragrances as in the example, and then volatilized. The changes over time in the amount of volatilization in Example and Comparative Example 1 were
Shown in the table. Comparative Example 2 A commercially available gel fragrance produced by mixing the top note, middle note, and end note fragrances used in Comparative Example 1 was stored in the same container as in Example 1 and volatilized. Table 1 shows the change in volatilization amount over time. Table 1 shows the fragrance tone compared to the standard state (sealed state in each example) at each time (volatilization rate): (1) "same", (2) "slightly different" and (3) "obviously different". The results are based on the olfactory judgments of 20 people, divided into three ranks.

A sheet of paper impregnated with a composite fragrance) was volatilized and the strength of the odor was compared with that of the example (judged by the sense of smell of 20 people). The results are shown in FIG. 3.
