JP7362232B2 - Volatile liquid stored in a transparent container and volatilized - Google Patents

Description

The present invention relates to a volatilized liquid stored in a transparent container and volatilized. More specifically, the present invention provides a volatilization liquid that is stored in a transparent container and volatilized, which maintains a stable appearance even when used for a long period of time in an environment exposed to sunlight and has excellent properties. Concerning a volatile liquid that maintains its aesthetic appearance. Furthermore, the present invention relates to a volatilizer having the volatilization liquid, a transparent container, and a volatilization member.

BACKGROUND ART Conventionally, volatile liquids containing volatile chemicals such as perfumes and pest repellents have been widely used to impart fragrance to spaces such as indoors and automobiles and to repel flying pests. BACKGROUND ART Conventionally, in order to improve the volatilization property, a volatilization liquid is used by being stored in a volatilization device designed to be impregnated with a volatilization member such as a plant material or a nonwoven fabric and then volatilized.

Conventional volatilization liquids were primarily used to add fragrance to indoor spaces, remove or reduce unpleasant odors, and repel flying pests, and did not place much emphasis on external beauty or interior design. However, in recent years, advances in construction technology and ventilation rate regulations under the Building Standards Act have led to efforts to reduce odor intensity in indoor spaces and reduce the intrusion of flying pests. There is a tendency to place equal emphasis on enhancing the interior quality of materials and providing excellent design effects, as well as on achieving the effects of volatile chemicals. Techniques have been reported so far to provide a volatilizer with a natural texture and enhance the design effect by using a volatilization member processed from natural materials. For example, Patent Document 1 proposes a volatilizer using rattan wood pieces as a volatilization member, and it has attracted attention as a volatilizer that gives a feel of wood grain and natural texture.

In recent years, various volatilizers with excellent design effects have been commercialized, and in order to further differentiate the products, improvements in design effects, addition of novel design effects, etc. are required.

When the container containing the volatile liquid is made transparent, the volatile liquid contained in the container becomes visible, and the design effect can be enhanced. In particular, the higher the transparency of the container containing the volatile liquid, the more improved the design effect can be expected. On the other hand, conventionally, paraffinic hydrocarbons are often used as a base for volatile liquids from the viewpoint of adjusting volatility, etc., and this allows for long-term use even if the capacity of the volatile device is reduced. are doing.

However, if a volatile liquid that uses paraffinic hydrocarbons as a base is stored in a transparent container and used in an environment where it is exposed to sunlight (by a window, inside a car, etc.), the volatile liquid may become cloudy, separate, or precipitate. This has the disadvantage that the appearance of the volatile liquid deteriorates over time. In particular, transparent containers with high transparency or containers with a high proportion of transparent areas have a high design effect, but because they have high sunlight transmittance, there is a noticeable tendency for the appearance of volatile liquid to deteriorate due to exposure to sunlight. It has the disadvantage of becoming

Conventionally, for volatile liquids whose appearance may deteriorate due to exposure to sunlight, it is possible to prevent sunlight from penetrating into the container by coloring the material forming the container or covering the container with colored shrink film. Measures are being taken to reduce this. However, such a method has the drawback that a transparent container cannot be used and the design effect is sacrificed.

Based on this conventional technology, the volatilization liquid is stored in a transparent container and volatilized, and even when used for a long period of time in an environment exposed to sunlight, it maintains a stable appearance and has an excellent aesthetic appearance. The purpose is to provide a volatile liquid that can retain

Further, when the volatile liquid of the present invention is made transparent, it may be either colorless and transparent or colored and transparent. Normally, when a transparent (particularly colorless and transparent) volatile liquid stored in a transparent container becomes cloudy, separates, or precipitates, changes in its appearance are easily visible and the aesthetic appearance is easily damaged. It is now possible to maintain a stable appearance even when stored and exposed to sunlight, and even transparent (especially colorless and transparent) volatile liquids can be stored in transparent containers to maintain their appearance. can do. In addition, in order to make the volatile liquid of the present invention colored transparent or colored opaque, a coloring agent such as a pigment or dye may be added.

[container]
The volatile liquid of the present invention is used by being stored in a transparent container. Conventional volatile liquids stored in transparent containers have the disadvantage that when exposed to sunlight, the sunlight transmitted through the transparent container causes cloudiness, separation, precipitation, etc., resulting in changes in appearance. Even when the volatile liquid of the present invention is housed in a transparent container and exposed to sunlight, cloudiness, separation, precipitation, etc. are suppressed, and the appearance can be maintained stably.

In the present invention, a transparent container is a container in which at least a portion of the outer circumferential surface of the container is provided with a transparent region whose transparency is ensured so that the inside can be visually recognized.

The transparent container containing the volatile liquid of the present invention may be either colorless and transparent or colored and transparent, but colorless and transparent is preferred. Colorless and transparent containers have the advantage of increasing internal visibility and exhibiting excellent design effects, but have the disadvantage that if the external appearance of the contained volatile liquid changes, it is easy to see and the reduction in design effects is easily felt. However, with the volatile liquid of the present invention, the appearance can be maintained stably even when exposed to sunlight, so the disadvantages of using a colorless and transparent container can be avoided and the advantages can be enjoyed.

In addition, the higher the transparency of the transparent container, the higher the internal visibility and the better the design effect, but on the other hand, the higher the transparency of the transparent container, the higher the proportion of sunlight that passes through the transparent container. Conventional volatilization liquids have the disadvantage that they cause noticeable changes in appearance. On the other hand, the volatile liquid of the present invention can stably maintain its appearance even if it is housed in a transparent container and exposed to sunlight. In view of the effects of the present invention, preferred examples of the transparent container for accommodating the volatile liquid of the present invention include containers in which at least a portion of the transparent region is provided with high transparency. More specifically, the transparency of the transparent region is such that the light transmittance at any wavelength from 400 nm to 700 nm is 70% or more, preferably 80% or more, more preferably 85% or more, particularly preferably 88% or more. % or more. The light transmittance can be determined by cutting out a test piece of an appropriate size from the container and measuring it using a spectrophotometer.

In the transparent container used in the present invention, the transparent region (particularly the region whose light transmittance in the range of 400 nm to 700 nm satisfies the above range) may be provided in at least a part of the transparent container; It does not have to be provided on the entire surface of the transparent container. From the viewpoint of design effect, the proportion occupied by the transparent area in the transparent container used in the present invention is, for example, when the outer circumferential surface area excluding the bottom surface (bottom) of the transparent container is 100, the area ratio of the transparent area is 30. % or more, preferably 60% or more, more preferably 80% or more.

The material of the transparent container used in the present invention is not particularly limited as long as it is transparent, and examples thereof include glass; synthetic resin such as polyethylene, polypropylene, and polyethylene terephthalate. Among these, glass is preferred from the viewpoint of high transparency and design.

The shape of the transparent container used in the present invention is not particularly limited as long as it has an opening, and may be appropriately set in consideration of the interior design of the volatilizer.

2. Volatilizer The volatilizer for volatilizing the volatilization liquid may be configured so that the volatilization liquid contained in the transparent container is absorbed by the volatilization member and volatilized, and its configuration is not particularly limited. However, as a preferable example, the transparent container has an opening, the volatilization liquid contained in the transparent container, and a volatilization member that absorbs and volatilizes the volatilization liquid, and at least one of the volatilization members An example is a volatilizer installed so that a portion thereof is exposed outside the container through the opening.

The volatilization member may, for example, integrally have a function of sucking up the volatilized liquid in the container and a function of volatilizing it, and may be configured to directly contact the volatilized liquid contained in the container. Further, for example, the volatilization member is connected to a suction member having a function of sucking up the volatilized liquid in the container, and the volatilized liquid in the container is supplied and absorbed through the suction member, and the volatilized liquid is may be configured to volatilize.

The material of the volatilization member is not particularly limited as long as it can absorb and volatilize the volatilization liquid, but examples include natural fibers such as cotton, vegetable fibers, pulp, rayon, polyester, polyethylene terephthalate, polypropylene, polyethylene, etc. Examples include fibrous materials such as synthetic fibers or mixed fibers thereof; wood materials such as wood chips, rattan, bamboo, and sora; and resin sponge materials such as urethane foam. Further, when the volatilization member is formed of a fibrous material, it is preferably a nonwoven fabric, but it may also be a woven fabric, a knitted fabric, or the like. The shape of the volatilization member is not particularly limited, and may be any one of a sheet shape, a rod shape, a band shape, a string shape, and the like.

When the wicking member is connected without having the function of sucking up the volatilized liquid in the container, the material and shape of the wicking member are not particularly limited, and may be made of the same material as the volatilizing member. You can use one with the same shape or shape.

EXAMPLES The present invention will be explained in more detail by showing Examples and Comparative Examples below, but the present invention is not limited thereto.

Test example 1
A volatile liquid (fragrance composition) having the composition shown in Table 1 was prepared. Approximately 54 g of each volatile liquid was poured into an approximately 94 mL transparent glass container (transmittance of approximately 90% at all wavelengths from 400 nm to 700 nm in all areas of the outer peripheral surface area of the transparent container, excluding the bottom). was filled. Next, eight volatilization members made of rattan stick-shaped (length 180 mm, diameter approximately 3 mm) are put into the opening of the transparent glass container, one end of the volatilization members is immersed in the volatilization liquid, and the volatilization members are A volatilizer was obtained by installing the container so that the other end of the container was exposed through the opening of the transparent glass container. This volatilizer was left for one week near a window in a room exposed to direct sunlight, and the appearance of the volatilized liquid before and after being left still was visually observed and evaluated according to the following criteria.
<Criteria for judging the appearance of volatile liquid>
○: No clouding, separation, or precipitation was observed, and the appearance was transparent.
Δ: Slight turbidity, separation, or precipitation occurred, but the overall appearance was transparent and good.
×: Cloudiness, separation, or precipitation was observed, and the appearance was poor.
XX: Cloudiness, separation, or precipitation was significantly observed, and the appearance was extremely poor.

The results obtained are shown in Table 1. When paraffinic hydrocarbons and fragrances were included, after being left standing in an environment exposed to sunlight, cloudiness occurred and the appearance deteriorated (Comparative Example 1). Furthermore, even when ethanol or monopropylene glycol monophenyl ether was added together with paraffinic hydrocarbons and fragrances, it was not possible to prevent the appearance from deteriorating after being left standing in an environment exposed to sunlight. On the other hand, when an organic solvent that does not contain a cyclic structure in its molecule and has an ether bond and/or an ester bond is added together with a paraffinic hydrocarbon and a fragrance, after being left standing in an environment exposed to sunlight, No clouding, separation, or precipitation was observed, and the same excellent appearance as before standing was maintained (Examples 1 to 9).

Test example 2
A volatile liquid (fragrance composition) having the composition shown in Table 2 was prepared and left to stand for one week under the same conditions as in Test Example 1 and exposed to sunlight for one week. The appearance of the volatile liquid before and after standing was visually observed and evaluated according to the criteria shown in Test Example 1 above.

The results obtained are shown in Table 2. These results show that even at a low content of 2.5% by weight, 3-methoxy-3-methyl-1-butanol does not change the appearance of volatile liquids containing paraffinic hydrocarbons and fragrances due to exposure to sunlight. It has become clear that this can be effectively suppressed.

Reference test example 1
A volatile liquid (fragrance composition) having the composition shown in Table 3 was prepared and allowed to stand for one week under the same conditions as in Test Example 1 and exposed to sunlight for one week. The appearance of the volatile liquid before and after standing was visually observed and evaluated according to the criteria shown in Test Example 1 above.

The results obtained are shown in Table 3. From these results, it was confirmed that volatile liquids containing hydrocarbon fragrances (limonene) or alcohol fragrances (phenylethyl alcohol) mixed with paraffin hydrocarbons as individual fragrances cause significant clouding when exposed to sunlight, and the fragrance In particular, it has become clear that volatile liquids containing hydrocarbon-based fragrances and alcohol-based fragrances tend to change in appearance when exposed to sunlight.
