Hereinafter, the method for providing the fragrance and the fragrance tool of the present invention will be described based on the preferred embodiment thereof.
In the method for providing fragrance of the present invention, the fragrance emitting means containing the fragrance component is attached to the body, and the fragrance generated from the fragrance emitting means is provided to the wearer. This allows the wearer to perceive the fragrance.

The fragrance emitting means is detachably arranged and used on a part of the body of the wearer who is the user of the present invention. In the present invention, the fragrance emitting means is arranged in a predetermined area of the body. As shown in FIGS. 1 and 2, the fragrance releasing means releases the fragrance to the nasal breath injection region 2 in which the anterior space region 1 of the body B through which the updraft generated by the heat from the body B flows flows. While the means are not arranged, the fragrance emitting means is arranged in the side region 3 located on the left and right of the nasal breath injection region 2 or the body proximity region 4 located on the body B side of the nasal breath injection region 2.

An updraft generated by heat from the body B flows in the front space region 1, and the updraft is also generated in the side region 3 and the body proximity region 4. In order to study the updraft and the airflow near the surface of the body such as breathing, the present inventors irradiate the volatile components such as olive oil mist diffused around the body with laser scattered light, and the volatile components. The diffusion behavior of the light was photographed with a high-sensitivity camera (for example, an eye scope manufactured by Shin Nihon Air Conditioning Co., Ltd.), and the air flow was observed. As a result, it was found that in the nasal breath injection region 2, the volatile components move due to the exhalation from the nose, that is, the downdraft caused by the nasal breath, and the volatile components are temporarily reduced in density. Then, it was found that the air near the mouth simply enters the nose from the nose. That is, in the nasal breath injection region 2, when the nasal breath is discharged, a strong unidirectional airflow in the direction away from the nose is generated due to the tubular shape of the nasal cavity. , The aroma component is only released in the direction away from the nose by nasal breath, and is not efficiently delivered to the wearer's nose. On the other hand, when inhaling through the nose, a strong unidirectional airflow toward the nose is not generated, and the air near the nose radiates back toward the nose. Therefore, if the fragrance emitting means is arranged in the nasal breath injection region 2, the fragrance component is only released in the direction away from the nose by the nasal breath, and is not efficiently delivered to the wearer's nose. It was also found that when the fragrance emitting means is arranged in the side region 3 or the body proximity region 4, the updraft due to the body temperature and the inspiration from the nose combine 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 anterior space region 1, convection is generated between the airflow that rapidly flows into the nose in a reverse radial manner and the downdraft due to the nasal breath. Based on the above findings, the present inventors have arranged the fragrance emitting means in the side region 3 or the body proximity region 4 and put them on the updraft due to body temperature and the convection generated by the nasal breath, and the fragrance generated from the fragrance emitting means. That is, the present invention has been achieved in which a volatilized aromatic component is supplied to the nose.

In the method for providing fragrance of the present invention, the fragrance emitting means is arranged in the predetermined regions 3 and 4 described above, and the fragrance component volatilized by the volatile amount per unit area described above is placed on the convection generated on the body surface and supplied to the nose. Therefore, the aromatic component can be efficiently supplied to the wearer's nose in an appropriate amount. As a result, the scent is provided with an appropriate intensity, so that the wearer specifically perceives the scent appropriately, while the people around the wearer do not easily perceive the scent. That is, the wearer can personally enjoy the fragrance. Moreover, since it is not necessary to excessively volatilize the volatile component (fragrance component) in order for the wearer to perceive the scent, the cost of the volatile component (fragrance component) can be reduced. Further, since the fragrance component is supplied to the nose on the convection, the airflow generated by the airflow generating means may or may not be used, such as a blower fan or a spraying device. Can be minimized. As a result, the scent can be provided in a state of being naturally volatilized or close to it, and the scent emitting means can be made compact. However, if an excessively strong airflow that promotes the volatilization of the aroma component too much or disturbs the updraft caused by body temperature and the convection caused by nasal breath is generated, an appropriate amount of the aroma component is added to the updraft caused by body temperature and the convection caused by nasal breath. Becomes difficult to supply to the nose.

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