Detailed description of the invention

Patent Documents 1 to 4 disclose the use of a scent cartridge in a form that can be attached to a necklace or the like. Patent Literature 2 describes that a scent cartridge is attached to a collar of a shirt. However, there is still room for study on the method of providing the fragrance by wearing these fragrances in terms of supplying the fragrance of the fragrance specifically to the wearer and efficiently supplying the fragrance to the wearer. Was.

Accordingly, the present invention relates to a method for providing a fragrance capable of solving the above-mentioned disadvantages of the prior art and a fragrance used for the method.

Hereinafter, the method for providing fragrance and the fragrance of the present invention will be described based on preferred embodiments.
In the method for providing fragrance of the present invention, fragrance releasing means containing a fragrance component is worn on a body, and fragrance generated from the fragrance releasing means is provided to a wearer. Thereby, the wearer can perceive the fragrance.

The fragrance releasing means is used by being detachably mounted on a part of the body of the wearer who is the user of the present invention. In the present invention, the fragrance releasing means is arranged in a predetermined region of the body. As shown in FIG. 1 and FIG. 2, the fragrance releasing means emits fragrance to a nose breath ejection area 2 in which a nose breath is directly blown out of a front space area 1 of the body B through which an updraft generated by heat from the body B flows. While the means is not arranged, the fragrance releasing means is arranged in the side area 3 located on the left and right of the nose breath ejection area 2 or in the body proximity area 4 located on the body B side of the nose breath ejection area 2.

(4) In the front space region 1, an updraft generated by heat from the body B flows, and the ascending airflow also occurs in the side region 3 and the body proximity region 4. The present inventors irradiate a laser scattered light to a volatile component such as an olive oil mist diffused around the body in order to examine the airflow flowing near the surface of the body such as the rising airflow and breathing, and the volatile component Was photographed with a high-sensitivity camera (for example, an eye scope manufactured by Shin Nippon Air Conditioning Co., Ltd.) to observe the air flow. As a result, in the nose breath ejection area 2, it was found that volatile components move due to exhalation from the nose, that is, a downdraft due to the nose breath, and the volatile components are temporarily reduced in density. Then I found that air near the mouth simply entered the nose from the nose. In other words, when the nose breath ejection area 2 discharges a nose breath, a strong one-way airflow in a direction away from the nose is generated due to the cylindrical shape of the nasal cavity. In addition, the fragrance component is only released in the direction away from the nose by breath, and is not efficiently delivered to the nose of the wearer. On the other hand, when breathing in from the nose, a strong one-way airflow toward the nose is not generated, and air near the nose is directed toward the nose in a reverse radial manner. For this reason, if the fragrance releasing means is arranged in the nose breath ejection area 2, the fragrance component is only released in the direction away from the nose by the nose breath, and is not efficiently delivered to the nose of the wearer. Further, it has been found that when the fragrance releasing means is disposed in the side region 3 or the body proximity region 4, the rising airflow due to the body temperature and the inhalation from the nose are combined to generate an airflow that rapidly flows into the nose in a reverse radial manner. . That is, in the side region 3 and the body proximity region 4 in the front space region 1, there is a convection between the airflow that rapidly flows in the nose in a reverse radial direction and the downward airflow caused by the nose breath. Based on the above findings, the present inventors arranged the fragrance releasing means in the side region 3 or the body proximity region 4 and put it on the rising airflow due to body temperature and the convection generated by the nose breath, the fragrance generated from the fragrance releasing means, That is, the present invention has been achieved in which the volatile fragrance component is supplied to the nose.

In the method for providing fragrance of the present invention, the fragrance releasing means is arranged in the above-mentioned

predetermined areas

3 and 4, and the fragrance component volatilized in the above-mentioned volatilization amount per unit area is supplied to the nose by convection generated on the body surface. Therefore, the fragrance component can be supplied to the wearer's nose in an appropriate amount and efficiently. Thereby, the scent is provided with an appropriate intensity, so that the wearer specifically perceives the scent appropriately, while it is difficult for persons around the wearer to perceive the scent. That is, the wearer can enjoy the fragrance personally. Moreover, it is not necessary to excessively volatilize the volatile component (fragrance component) in order for the wearer to perceive the scent, so that the cost of the volatile component (fragrance component) can be reduced. In addition, since the fragrance is supplied to the nose by the convection, the airflow generated by the airflow generation means may or may not be used even if the airflow generation means such as a blowing fan or a spray device is used. Can be minimized. Accordingly, the fragrance can be provided in a state where the fragrance is volatilized naturally or in a state close thereto, and the fragrance releasing means can be made compact. However, if an excessive amount of fragrance is promoted, or if an excessively strong airflow is generated that disturbs the convection caused by the rising airflow and nasal breath caused by body temperature, an appropriate amount of the aromatic component is added to the convection caused by the rising airflow caused by body temperature and the nasal breath. Is difficult to supply to the nose.

According to the present invention, as described above, by providing the fragrance releasing means at an appropriate place, it is possible to provide an effective fragrance. The relationship between the location of the fragrance releasing means and the degree of fragrance perception can be confirmed by, for example, a fragrance perception test in a test example described later.

In this specification, the anterior space region 1 is a space region located below the lower end of the nose of the upper body and along the body surface on the ventral side (front side) of the frontal plane. The "lower end of the nose" means the lower end of the nasal septum.

When the body B is viewed from the side, the body proximity region 4 is closer to the surface of the body B than the nasal breath ejection region 2 as shown in FIG. That is, the body proximity region 4 is a space region from the surface of the body B to the rear boundary line 22 of the nose breath ejection region 2 and gradually expands downward. The body proximity area 4 overlaps the nose breath ejection area 2 when the body B is viewed from the front.

As described above, the fragrance releasing means is not arranged in the nasal breath ejection area 2, but is arranged in the side area 3 or the body proximity area 4. The fragrance releasing means is used by being arranged at an arbitrary position in the side region 3 or the body proximity region 4. The side region 3 and the body proximity region 4 are regions in which air flowing into the nose flows, as described later, and both are formed around the nasal breath ejection region 2. The side region 3 and the body proximity region 4 may partially overlap each other at a boundary portion between each other.

In the present invention, in the side region 3 or the body proximity region 4, the fragrance releasing means may be arranged so as to be separated from the body surface to the front side. The term “arranged to be separated from the body surface to the front side” means to arrange the body B at a position horizontally moved from the body surface to the front side at each height position of the body B as shown in FIG. The position horizontally moved from the body surface to the front side includes, for example, a position of a line f along the body surface at a predetermined separation distance shown in FIG.

In this case, the fragrance releasing means may be arranged in the left side area 31 or in the right side area 32. The area along the surface of the body B in the body proximity area 4 may be directly affected by the ascending airflow due to heat, or turbulence may occur or air may accumulate. In the case of disposition, the distance between the body surface and the fragrance releasing means is preferably within 70 mm, more preferably within 50 mm, and preferably 1 mm or more, more preferably 5 mm or more, still more preferably 10 mm or more, and even more. Preferably it is 30 mm or more. The preferred range of the separation distance between the body surface and the fragrance releasing means may overlap between the side region 3 and the body proximity region 4. When the fragrance releasing means is arranged at a distance from the body surface, the distance between the body surface and the opening which is the fragrance discharging port of the fragrance releasing means, for example, the distance between the fragrance release window 15 described later and the body surface. Preferably, the distance is the aforementioned preferred distance between the body surface and the fragrance emitting means. When the fragrance releasing means is a fragrance device, the fragrance device preferably includes a support portion 12 (wearing portion 13) for maintaining a distance between the opening and the body surface at a preferable separation distance.

In the present invention, the fragrance releasing means may be arranged in one or both of the side region 3 and the body proximity region 4. From the viewpoint of easily supplying the fragrance component to the nose, it is preferable to arrange the fragrance release means near the collarbone in the side region 3 or near the lower jaw in the body proximity region 4. In the vicinity of the clavicle or the lower jaw, the distance between the body surface and the fragrance releasing means is set to be easy to put the fragrance component on the convection flowing into the nose when the fragrance releasing means is placed away from the body surface on the front side. It is preferably within 70 mm, more preferably within 50 mm, and preferably 1 mm or more, more preferably 5 mm or more, still more preferably 10 mm or more, and still more preferably 30 mm, from the viewpoint of the direct influence of the updraft, turbulence and air accumulation.

In the front view of the body B viewed from the front, a grid pattern T1 centered on a vertical line passing through the lower end of the nose is assumed as shown in FIG. The lattice pattern T1 indicates the position of the front space region 1 of the body B at the intersection of the lattice in the front view, and has a length in the height direction of 60 cm and a length in the left-right direction of 60 cm. The grid pattern T1 has a plurality of vertical lines centered on a reference line CL2 which is a vertical line passing through the lower end of the nose, and a plurality of parallel lines orthogonal to the vertical line. It is composed of a plurality of squares of 5 cm × 5 cm serving as vertices. The grid pattern T1 has six vertical lines e on each of the left and right sides of the reference line CL2 with the reference line CL2 as the center. In the height direction, the parallel lines d of the grid pattern T1 are referred to as a first parallel line d1, a second parallel line d2, a third parallel line d3,... In order from the lower end of the nose in the height direction. Further, in the left-right direction, the respective vertical lines e of the lattice pattern T1 are referred to as a first vertical line e1, a second vertical line e2, a third vertical line e3,... The right side in the left-right direction is the right side of the body B. In the lattice pattern T1, the seventh vertical line e7 becomes the reference line CL2.
The fragrance emitting means is preferably arranged in a region R1 defined by the first and sixth parallel lines d1 and d6 and the fourth and tenth vertical lines e4 and e10 in the grid pattern T1, More preferably, they are arranged in a region R2 defined by the fifth parallel lines d2 and d5 and the fifth and ninth vertical lines e5 and e9. As described above, it is preferable that the fragrance releasing means be arranged symmetrically with respect to the reference line CL2 which is a vertical line passing through the lower end of the nose, since the fragrance component is supplied to both the right and left nasal cavities in a balanced manner. However, even within these regions R1 and R2, the fragrance releasing means is not arranged in the nasal breath ejection region 2.

From the viewpoint of more surely supplying the fragrance component to the nose, in the front space region 1, when the distance from the body surface is 5 cm or more and 10 cm or less, the fifth parallel line on the seventh vertical line e7 in the lattice pattern T1. It is preferable that the fragrance releasing means is not arranged below d5 and below the ninth parallel line d9 on the sixth vertical line e6 and the eighth vertical line e8. In the front space region 1, when the distance from the body surface is within the range of 10 cm or more and 15 cm or less, the first vertical line e7 in the grid pattern T1, and the sixth vertical line e6 and the eighth vertical line e8 It is preferable not to dispose the fragrance releasing means below the eight parallel lines d8.

From the same viewpoint as above, when the distance from the body surface in the anterior space region 1 is in the range of 5 cm or more and 10 cm or less, the aromatic pattern is contained in any one of the following regions R3 to R7 in the lattice pattern T1. It is preferred to provide a release means. The following regions R3 to R7 overlap the side region 3 or the body proximity region 4 in the front view of the body B.

Hereinafter, the present invention will be described more specifically with reference to examples (test examples), but the present invention is not limited to such examples (test examples).

(Preparation of fragrance releasing means)
Approximately 7 mg of fragrances (fragrance compositions) A and B shown in Table 8 below were impregnated into fragrance test paper (manufactured by Capital Letter Western Paper) having a size of 12 mm × 6 mm and a thickness of 0.8 mm. The fragrance test paper was attached to a mount with a double-sided tape (manufactured by NITOMS, trade name: multi-purpose thick double-sided tape), and this was used as a fragrance releasing means. Further, a stick-shaped fixing portion was prepared so that the fragrance releasing means could be arranged away from the body surface. The fixing part can carry the fragrance releasing means at one end and fix the other end to the wearer's clothes. When the fixing portion is fixed to the wearer's clothes, the fixing portion protrudes forward from the wearer's clothes, and the fragrance emitting means can be arranged separately from the body.

[Aroma perception test 1]
The arrangement of the fragrance releasing means was set as follows, and the degree of perception of fragrance in each arrangement was evaluated. First, in the front view of the body viewed from the front, the above-described lattice pattern T1 was assumed (see FIG. 5). Then, the fragrance releasing means was arranged at each intersection of the vertical line and the parallel line of the lattice pattern T1. At this time, the separation distance between the fragrance emitting means and the body surface of the wearer at each location was made different. In the lattice pattern T1, the fragrance emitting means was arranged at a distance shown in Table 9 below from the frontal surface of the body to the front side. Further, the fragrance releasing means was arranged on the wearer's clothing surface via a double-sided tape. In this case, the distance from the body surface was 2 cm. When the separation distance was 7 cm or more, the fragrance releasing means was arranged using the above-mentioned fixing portion.
In Test Examples 1 to 8, the evaluation was performed using fragrances (fragrance compositions) A and B containing fragrance components having a fragrance potential of -6 or more. When perfume A is used, the perfume A is soaked in the perfume test paper 30 minutes after the perfume is soaked, and when perfume B is used, perfume B is permeated into the perfume test paper 20 hours after the perfume test paper is used. The degree of perception was evaluated.
Table 9 below shows the fragrances and the separation distances in Test Examples 1 to 8.

Six expert panels evaluated the degree of perception of fragrance generated from the fragrance releasing means at each location of the fragrance releasing means. At this time, the panel performed the operation of inhaling and exhaling in a standing posture about three times in 10 seconds, and evaluated whether or not the aroma could be sensed based on the following evaluation criteria. The evaluation points were determined by consultation between six specialized panels. FIGS. 8 to 15 show the evaluation results of the respective arrangement locations in Test Examples 1 to 8.
0: not detectable 1: barely detectable 2: detectable 3: detectable 4: detectable

結果 The results of FIGS. 8 to 13 show that when the fragrance emitting means is arranged in the side area or the body proximity area, the fragrance generated from the fragrance emitting means can be perceived. On the other hand, the results of FIGS. 12 to 15 show that at a position near the reference line CL2 passing through the lower end of the nose, if the separation distance from the body surface is 12 cm or more, it becomes difficult to sense fragrance. This is considered to be due to expiration from the nose in the nose breath ejection area. As shown in FIGS. 10 and 11, when the distance from the body surface is 7 cm, the nose breath ejection area is on the seventh vertical line e7 passing through the lower end of the nose, and is below the fifth parallel line d5. , And on the sixth and eighth vertical lines e6 and e8 adjacent to the seventh vertical line e7 and at a position below the ninth parallel line d9. The position of the nose breath ejection area also matches the results of Test Examples 9 and 10 (FIGS. 16 and 17) described later. In addition, as shown in FIGS. 12 and 13, when the distance from the body surface is 12 cm, the nose breath ejection area is located on the seventh vertical line e7 passing through the lower end of the nose, and the seventh vertical line e7. On the adjacent sixth and eighth vertical lines e6 and e8, it is shown that they exist at a position below the eighth parallel line d8 or a position below the ninth parallel line d9. 8 to 13, the body proximity region exists on the seventh vertical line e7 passing through the lower end of the nose, and on the sixth and eighth vertical lines e6 and e8 adjacent to the seventh vertical line e7. It was shown to be. From the results shown in FIGS. 10 and 11 and the results shown in FIGS. 12 and 13, at the intersection between the eighth parallel line d8 and the sixth vertical line e6 and at the intersection between the eighth parallel line d8 and the eighth vertical line e8. Although the degree of perception of the fragrance is different, it is considered that this is due to the fragrance potential AP of each fragrance component contained in the fragrances A and B.

As a result of Test Examples 1 to 8, when the fragrance releasing means is arranged in the side region, the distance between the fragrance releasing means and the body surface is preferably 15 cm or less, more preferably 10 cm or less, and still more preferably 5 cm or less. It has been shown. Further, it is preferable that the fragrance emitting means is arranged near the reference line CL2 in the side region.

[Aroma perception test 2]
As Test Examples 9 and 10, the degree of fragrance perception was evaluated in the same manner as in the above-described fragrance perception test 1 except that fragrance components having different fragrance potentials were used. The following were used as the aromatic components C to D. Aroma component C: sandal mysole core [registered trademark, manufactured by Kao Corporation, 2-methyl-4- (2,2,3-trimethyl-3-cyclopenten-1-yl) -2-buten-1-ol]. Aroma component D: oxacyclohexadecene-2-one [Habanolide (registered trademark) manufactured by Firmenich]
Next, 7 mg of each aroma component was soaked in a fragrance test paper. Table 10 below shows the distance between the fragrance releasing means and the body surface, the fragrance component and its fragrance potential in Test Examples 9 and 10. 16 and 17 show the evaluation results of the respective arrangement locations in Test Examples 9 and 10.

結果 The results of FIGS. 16 and 17 show that the fragrance potential of the fragrance component is more preferably −6 or more.
