Description

  The present invention is a fragrance tool which seals a liquid fragrance composition with a fragrance permeable film and volatilizes the fragrance in the liquid fragrance composition through the fragrance permeable film, and the fragrance is volatilized during use. Even so, the present invention relates to an fragrance that can stably maintain the external shape and can easily visually check the amount of the remaining fragrance.

  Conventionally, there has been known an fragrance made by sealing a fragrance using a fragrance-permeable film that does not allow liquid fragrance to leak out but permeates volatile fragrance (see, for example, Patent Document 1). In such an fragrance, since the fragrance is volatilized to the outside through the fragrance permeable film, the influence of external temperature, humidity, etc. on the volatilization rate of the fragrance is reduced, and the desired fragrance effect is sustained and stabilized. In addition to the advantage that it can be maintained, the liquid does not spill in any orientation, so there is an advantage that the degree of freedom in design is high.

  On the other hand, in the fragrance tool in which the fragrance is sealed with the fragrance permeable film, there is a drawback that the inside of the fragrance permeable film in the fragrance becomes negative pressure as the fragrance is volatilized during use. If the inside of the fragrance-permeable film of the fragrance becomes negative pressure, the fragrance-permeable film is pulled inside the fragrance, and the remaining fragrance sticks to the fragrance-permeable film. The defect that the visibility and external appearance of the residual amount of the fragrance | flavor inside worsen arise. Further, when the perfume permeable film is pulled inside the fragrance, the fragrance itself may be deformed and the shape thereof may be deteriorated.

Today, as various types of fragrances are commercialized, the fragrances not only have an excellent fragrance effect, but also have an indicator function for confirming the remaining amount of fragrance. A good appearance is also required. Therefore, it is important that the remaining amount of the fragrance can be easily confirmed and the appearance shape can be stably maintained even in the fragrance having the fragrance sealed with the fragrance permeable film.
JP-A-6-219479

  Therefore, the present invention is an fragrance that seals a liquid fragrance composition with a fragrance permeable film and volatilizes the fragrance in the liquid fragrance composition through the fragrance permeable film. It is an object of the present invention to provide an fragrance that can stably maintain the external shape even if it is volatilized, and can easily confirm the amount of the remaining fragrance visually.

The present inventor has intensively studied in order to solve the above-mentioned problems. As a result, the liquid fragrance composition is sealed with a fragrance permeable film, and the liquid fragrance composition is interposed through the fragrance permeable film. In the fragrance device that volatilizes the fragrance, (A) the fragrance and (B) the vapor pressure at 25 ° C. is 0.8 to 20 kPa as the liquid fragrance composition, and the permeation rate of the fragrance permeable film is 25 ° C. By using a combination of liquid ingredients that are 1 mg / day · cm ² or less, the fragrance can be contained in the fragrance even if the fragrance is volatilized with little effect on the volatilization rate of the fragrance composition. It was found that even when the fragrance was volatilized by use, the external shape could be stably maintained, and the amount of the remaining fragrance could be easily confirmed by visual observation, even though the portion did not become negative pressure and the fragrance was volatilized by use. The present invention has been completed by making further improvements based on such findings.

That is, the present invention is the following fragrance tools:
Item 1. A liquid fragrance composition is sealed with a fragrance permeable film, and is an fragrance that volatilizes the fragrance in the liquid fragrance composition through the fragrance permeable film, wherein the liquid fragrance composition is (A ) Perfume, and (B) a liquid component having a vapor pressure at 25 ° C. of 0.8 to 20 kPa and a permeation rate of the perfume permeable film of 1 mg / day · cm ² or less at 25 ° C. Fragrance, characterized by Item 2. The fragrance according to Item 1, comprising (B) a liquid component at a ratio of 5 to 99.9% by volume per total amount of the liquid fragrance composition.
Item 3. Item 3. The fragrance according to Item 1 or 2, wherein the liquid component is water and / or a lower alcohol.
Item 4. Item 4. The fragrance according to any one of Items 1 to 3, wherein a container having an opening is filled with the liquid fragrance composition, and the opening is sealed with the fragrance-permeable film.
Item 5. Item 5. The fragrance according to any one of Items 1 to 4, wherein the fragrance-permeable film is covered with a removable fragrance-impermeable film.
Item 6. Item 6. The fragrance according to any one of Items 1 to 5, which is supported by a detachable support.

  According to the fragrance of the present invention, even if the encapsulated fragrance is completely volatilized, the inside of the fragrance permeable film can be suppressed from becoming a negative pressure, and its external shape can be stably maintained. Moreover, the amount of the remaining fragrance can be easily confirmed visually.

  In addition, in a conventional fragrance tool in which a liquid fragrance composition is sealed with a fragrance-permeable film, a dye or an ultraviolet absorber in the fragrance composition is unavoidable in the fragrance tool as the sealed fragrance is volatilized. There was a problem that it was deposited and the appearance was impaired. On the other hand, according to the fragrance of the present invention, the problems of the conventional fragrance as described above are also solved, and even if the encapsulated fragrance is completely volatilized, the fragrance is not volatilized and is not evaporated. Since the component remaining in the layer does not cause precipitation or the like, it is possible to maintain a good appearance.

  The fragrance of the present invention is configured such that a specific liquid fragrance composition described later is sealed with a fragrance permeable film, and the fragrance in the liquid fragrance composition can be volatilized through the fragrance permeable film. It is characterized by that.

  In this specification, the fragrance-permeable film is a film made of a material that can permeate the fragrance and has a transmission speed at which the fragrance permeates the film is equal to or less than a volatilization speed at which the fragrance permeated through the film is volatilized. It is. Such a perfume permeable film is disclosed in, for example, International Publication No. 98/23304 pamphlet, Japanese Patent Application Laid-Open No. 6-219479, US Pat. No. 5,518,790, etc., and is known in the art. . The constituent material of the perfume permeable film is not particularly limited, but examples thereof include polyethylene, polypropylene, ethylene vinyl acetate copolymer, ethylene ethyl acrylate, paper, and a mixture thereof. As a preferable fragrance-permeable film material, linear low density polyethylene (LLDPE) is exemplified. In the fragrance of the present invention, the perfume permeable film may be a single layer film made of one kind of material, or a film in which two or more layers made of the same or different materials of the above members are laminated. There may be.

  The perfume permeable film may be colorless, colored and transparent, or opaque. For example, in order to make it possible to visually recognize the remaining amount of the fragrance composition in the fragrance through the fragrance permeable film, the fragrance permeable film may be colorless or colored and transparent.

  What is necessary is just to set suitably about the thickness of said fragrance | flavor permeation | transmission film according to the kind of fragrance permeation | transmission film material to be used, the kind of fragrance | flavor to be used, etc. Specific examples of the thickness of the perfume permeable film include, for example, 30 to 150 μm, preferably 30 to 70 μm.

The surface area occupied by the fragrance-permeable film in the fragrance of the present invention (the area of the portion where the fragrance can be volatilized in the fragrance) is the shape and purpose of use of the fragrance, and the type of the fragrance composition to be sealed. For example, when the fragrance of the present invention is used for indoor spaces, the surface area is about 1 to 150 cm ² , preferably about 5 to 50 cm ² .

  The fragrance | flavor of this invention should just hold | maintain in the state which enclosed the liquid fragrance | flavor composition by arrange | positioning the said fragrance | flavor permeable film in the part which volatilizes a fragrance | flavor. Therefore, the shape and structure of the fragrance of the present invention are not particularly limited as long as the fragrance can be volatilized through the fragrance permeable film. For example, the fragrance of the present invention may be one in which the liquid fragrance composition is surrounded only by the fragrance permeable film, or a liquid fragrance in combination with the fragrance permeable film and the fragrance non-permeable member. It may be one that surrounds the composition. In the present specification, the fragrance-impermeable member is a member that does not transmit not only the liquid fragrance but also the volatile fragrance (or can significantly suppress the transmission of the volatile fragrance). For such a perfume non-permeable member, various types of members such as glass, polyvinylidene chloride, polyethylene terephthalate, ethylene vinyl acetate copolymer, aluminum and the like are known, and these can be appropriately selected and used. . The perfume non-permeable member can take various forms such as a film, a sheet, a bag, and a container as long as it can be combined with the perfume permeable film and surround the liquid perfume composition.

As a preferred specific example of the fragrance device of the present invention, a liquid fragrance composition is filled in a fragrance-impermeable container having an opening, and the opening is sealed with the fragrance-permeable film. Can be mentioned. As a more specific example, the liquid fragrance composition is filled in a fragrance-impermeable container that has an opening of an area of about 5 to 50 cm ² and can be filled with a liquid fragrance composition of up to about 1 to 100 mL. , Those in which the opening is sealed with the fragrance-permeable film.

  Furthermore, as another preferred example of the fragrance of the present invention, a liquid fragrance composition is enclosed in a bag made of a fragrance-permeable film, or in a bag made of a fragrance-permeable film and a fragrance-impermeable film. The thing which becomes. As a specific example of the bag used in the fragrance, a bag having a planar shape that fits in an area having a vertical and horizontal length of 20 to 100 mm is exemplified. In addition, in this specification, a fragrance | flavor non-permeable film is a film of the material which does not permeate | transmit not only the liquid fragrance | flavor but the fragrance | flavor which volatilized (or can suppress transmission | permeation of the volatilized fragrance | flavor remarkably). The perfume non-permeable film member is appropriately selected according to the type of perfume used, but as an example, polyvinylidene chloride, polyethylene terephthalate, ethylene vinyl acetate copolymer, aluminum foil, ethylene vinyl acetate alcohol copolymer, etc. Is exemplified. The fragrance-impermeable film may be a single-layer film made of one kind of member or a film in which two or more kinds of layers are laminated.

  In addition, the fragrance of the present invention covers the surface of the fragrance-permeable film (the surface in contact with the outside air) with a removable fragrance-impermeable film before use in order to prevent the fragrance from evaporating. It is desirable to keep it. The fragrance-impermeable film is as described above.

  In addition, as described above, when not covered with a removable fragrance-impermeable film, the fragrance of the present invention comprises a fragrance-impermeable member in order to prevent the fragrance from evaporating before use. It is desirable to store it in a sealed state in the package.

  Furthermore, the fragrance of the present invention comprises a liquid fragrance composition sealed with a fragrance-impermeable film configured to be damaged by an external stimulus such as pressurization, and the fragrance-impermeable film. The sealed liquid fragrance composition may be further sealed with a fragrance permeable film. If it is a fragrance of such an aspect, at the time of use, a fragrance | flavor is volatilized from a fragrance | flavor permeation | transmission film by adding irritation | stimulation from the outer side of a fragrance | flavor permeation | transmission film and damaging an internal perfume non-permeability | transmission film It becomes possible.

  In the fragrance of the present invention, the liquid fragrance composition encapsulated therein contains (A) a fragrance as an essential component that can be transmitted through the fragrance-permeable film and volatilized.

In the fragrance of the present invention, a fragrance containing hexyl acetate is exemplified as an example of a suitable fragrance.

As the fragrance (A) used in the present invention, from the viewpoint of enhancing the permeability to the fragrance-permeable film, preferably, the ester-based fragrance component is 10 to 100% by weight, more preferably 20 to 20%, based on the total amount of the fragrance component. Examples include fragrances contained in about 100% by weight. From the viewpoint that (A) fragrances contained in the liquid fragrance composition have excellent volatility, the vapor pressure per total amount of the (A) fragrances What contains 4 Pa or more of fragrance | flavor components in the ratio of 5 to 100 weight% is suitable.

  The blending ratio of the (A) fragrance used in the present invention is uniformly defined depending on the type of fragrance used, the intensity of the fragrance imparted to the fragrance, the type of the liquid component (B) described later, etc. In general, the ratio of (A) fragrance is 0.1 to 95% by volume, preferably 15 to 90% by volume, more preferably 40 to 90% by volume, based on the total amount of the liquid fragrance composition. Is done.

Furthermore, the liquid fragrance composition enclosed in the fragrance of the present invention has (B) a vapor pressure at 25 ° C. of 0.8 to 20 kPa in addition to the above (A) fragrance, and the fragrance permeable film. A liquid component having a permeation rate of 1 mg / day · cm ² or less at 25 ° C. (hereinafter sometimes simply referred to as “(B) liquid component”).

  The vapor pressure of the liquid component (B) is preferably 2.5 to 20 kPa, more preferably 3.0 to 8.0 kPa.

In addition, about the permeation | transmission rate in 25 degreeC with respect to the said fragrance | flavor permeation | transmission film of the said (B) liquid component, it measures for every form of fragrance | flavor, and is measured according to the following method. First, only the liquid component is sealed with a fragrance-permeable film, similar to the fragrance of the present invention, except that only the liquid component of interest is enclosed instead of the liquid fragrance composition. Next, this is left for 6 to 240 hours (the time is appropriately set based on the size of the fragrance, etc.), 25 ° C., normal pressure (1 atm), and relative humidity 40%, and then enclosed inside. The remaining amount of the remaining liquid component is measured, and the volatilization rate (mg / day · cm ² ) of the liquid component per unit area of the perfume permeable film is calculated.

  The liquid component (B) is not particularly limited as long as it satisfies the vapor pressure and permeation rate described above, but for example, water; methanol, ethanol, propanol, isopropyl alcohol, butanol, pentanol, etc. The lower alcohol having 1 to 5 carbon atoms may be appropriately selected. Among these, from the viewpoint of effectively suppressing negative pressure inside the fragrance-permeable film of the fragrance when used, preferably water (vapor pressure at 25 ° C. 3.16 kPa) and ethanol (25 ° C. A vapor pressure of 7.87 kPa) is exemplified. As for the liquid component (B), one component may be used alone, or two or more components may be used in combination.

  The blending ratio of the (B) liquid component contained in the liquid fragrance composition differs depending on the type of (A) fragrance used, the type of (B) liquid component used, etc., but cannot be specified uniformly. Usually, the ratio by which the total amount of the liquid component (B) is 5 to 99.9% by volume, preferably 10 to 85% by volume, and more preferably 10 to 60% by volume is exemplified per the total amount of the liquid perfume composition. .

  In the liquid fragrance composition encapsulated in the fragrance of the present invention, the (A) fragrance and (B) liquid component do not necessarily need to be in a dissolved state, the (A) fragrance and (B) When the compatibility of the liquid component is low, they may exist in a state where they are separated from each other. In other words, the fragrance of the present invention has an advantage that the conventional fragrance composition does not necessarily contain the surfactant that is required when the fragrance and the liquid component have low compatibility.

In this way, by combining (A) perfume and (B) liquid components in combination,
Even if the fragrance is volatilized, the inside of the fragrance permeable film of the fragrance is suppressed to a negative pressure, and the external shape of the fragrance is stably maintained, and the amount of the remaining fragrance is visually confirmed. It becomes possible to make it possible.

  In addition, the liquid fragrance composition enclosed in the fragrance of the present invention contains the liquid component (B), so that even an additive having a low compatibility with the fragrance (A) is blended. There is also an advantage that additional value can be added to the fragrance. For example, when the liquid component (B) is water, a water-soluble pigment, a water-soluble deodorant and the like can be blended, and the fragrance composition has a desired color tone or imparts a deodorizing effect. You can. In addition, when an ultraviolet absorber is blended in the fragrance composition, the ultraviolet absorber may precipitate during use.

Criteria A : After 35 days, the fragrance composition does not stick to the fragrance-permeable film on the entire surface of the fragrance, and the remaining amount can be easily confirmed. The shape of the fragrance has not changed at all. (Refer to the representative example shown in FIG. 2)
○: After 35 days, the fragrance composition slightly sticks to the fragrance-permeable film at the center of the fragrance, but the remaining amount can be confirmed. When the fragrance is observed from the side, almost no deformation of the fragrance is observed. (Refer to the representative example shown in FIG. 2)
(Triangle | delta): It is in the state which the fragrance | flavor composition stuck to the fragrance | flavor permeation | transmission film also in the center part of fragrance | flavor and the other part after 35 days. It is difficult to confirm the remaining amount. When the fragrance is observed from the side, deformation is observed. (Refer to the representative example shown in FIG. 2)
X: After 35 days, the fragrance composition is strongly attached to the fragrance-permeable film in the central portion of the fragrance and other portions. It is difficult to confirm the remaining amount. When the fragrance is observed from the side, it is recognized that the fragrance is greatly deformed. (See representative example shown in FIG. 2).

<Measurement of decrease in liquid perfume composition>
By subtracting the weight of the fragrance after 13, 21, and 35 days from the weight of the fragrance before the start of the test, the weight loss of the liquid fragrance composition was determined, and the reduction rate (%) of the fragrance composition was calculated.

<Evaluation results>
Table 4 shows the obtained results. From this result, water (vapor pressure at 25 ° C .: 3.16 kPa; volatilization rate of fragrance permeable film used: 0.25 mg / day · cm ² ) or ethanol (vapor pressure: 7.87 kPa at 25 ° C.) was used. The combination of a volatilization rate of 0.94 mg / day · cm ² ) with respect to the fragrance-permeable film may improve the state of the liquid fragrance composition remaining in the fragrance and the shape of the fragrance. confirmed. On the other hand, in the case of a fragrance composition containing only the fragrance, the shape of the fragrance is deformed due to the negative pressure inside the fragrance, and the remaining amount of the fragrance composition cannot be easily visually confirmed. It was. In addition, the decrease rate of a fragrance | flavor composition, ie, the volatilization rate of a fragrance | flavor, the influence by the presence or absence of ethanol or water was hardly recognized. Moreover, in the fragrance of the examples, no precipitate was observed in the remaining fragrance composition even after 35 days from the start of use.

Example 5-8
A fragrance was prepared in the same manner as in Examples 1-4 and Comparative Example 1 except that the fragrance B (squash-like fragrance) was used. The composition of the fragrance composition used is as shown in Table 5, and the composition of fragrance B used in Examples 5-8 and Comparative Example 2 is as shown in Table 6.

  In the same manner as in Examples 1-4 and Comparative Example 1 above, the state of the liquid fragrance composition remaining in the fragrance, the shape of the fragrance, the decrease in the liquid fragrance composition of the fragrance manufactured in this way The amount was evaluated. The results are shown in Table 7. As can be seen from the table, even when the fragrance B was used, the same results as in Examples 1-4 and Comparative Example 1 were obtained. Similarly to Example 1-4, in the fragrance of Example 5-8, no precipitate was found in the remaining fragrance composition even after 35 days from the start of use.

Examples 9-12
A fragrance was prepared in the same manner as in Examples 1-4 and Comparative Example 1 except that the fragrance C (tropical fruit-like fragrance) was used. The composition of the used fragrance composition is as shown in Table 8, and the composition of fragrance C used in Examples 9-12 and Comparative Example 3 is as shown in Table 9.

  In the same manner as in Examples 1-4 and Comparative Example 1 above, the state of the liquid fragrance composition remaining in the fragrance, the shape of the fragrance, the decrease in the liquid fragrance composition of the fragrance manufactured in this way The amount was evaluated. The results are shown in Table 10. As can be seen from the table, even when the fragrance C was used, the same results as in Examples 1-4 and Comparative Example 1 were obtained. In addition, as in Example 1-4, in the fragrance of Examples 9-12, no precipitate was observed in the remaining fragrance composition even after 35 days from the start of use.

Examples 13-16
A fragrance was prepared in the same manner as in Examples 1-4 and Comparative Example 1 except that perfume D (tropical fruit-like perfume) was used. The composition of the fragrance composition used is as shown in Table 11, and the composition of the fragrance D used in Examples 13-16 and Comparative Example 4 is as shown in Table 12.

  In the same manner as in Examples 1-4 and Comparative Example 1 above, the state of the liquid fragrance composition remaining in the fragrance, the shape of the fragrance, the decrease in the liquid fragrance composition of the fragrance manufactured in this way The amount was evaluated. The results are shown in Table 13. As can be seen from the table, even when the fragrance D was used, the same results as in Examples 1-4 and Comparative Example 1 were obtained. Further, as in Example 1-4, in the fragrance of Examples 13-16, no precipitate was observed in the remaining fragrance composition even after 35 days from the start of use.
