Hereinafter, an embodiment of the flavor inhaler will be described with reference to the drawings. The purpose of the following description is to explain the present invention in detail and is not intended to limit the present invention.

As shown in FIG. 1, the flavor taster 11 of the embodiment includes: a cylindrical (cylindrical) holding body 12, which extends from the suction port end 12A to the front end 12B; and a combustion-type heat source 13, which is provided to hold The front end 12B of the body 12 contains activated carbon; the first fragrance 13a, which is carried by the combustion-type heat source 13; the fragrance source 16, which is arranged in the holder 12; the second fragrance 16a, which is carried by the fragrance source 16; cup 17, which stores the fragrance source 16 inside; aluminum lamination paper 18, which is inside the holder 12 and intervenes in the space with the cup 17; the filter part 21, which is It is provided on the inside of the holder 12 and on the side of the suction port end 12A; and a capsule 22 (perfume capsule), which is embedded in the filter portion 21 and contains the third perfume 22a.

When the fragrance taster 11 includes the first fragrance 13a carried on the combustion-type heat source 13 and the second fragrance 16a carried on the fragrance source 16, the capsule 22 containing the third fragrance 22a may not be provided. Alternatively, when the flavor taster 11 includes the first flavor 13a supported on the combustion-type heat source 13 and the capsule 22 including the third flavor 22a, the second flavor 16a supported on the flavor source 16 may not be provided.

The first fragrance 13a contains a compound selected from the group consisting of anethole, 2-pinene, β-citronellol, sesame acetate, limonene, anisaldehyde, 4-terpineol, 2-β-pinene, jasmonone, juniper , Linalool, 1,8-eucalyptus phenol, phenethyl alcohol, and myristyl ether are at least one group. The first fragrance 13a may be a single fragrance compound or a mixture of fragrance compounds. Make In the case where the above-mentioned perfume compound is used for the first perfume 13a, the perfume compound is stably maintained when the flavor inhaler 11 is stored, and the user does not provide an unpleasant aroma when the flavor inhaler 11 is used.

Preferably, the first fragrance 13a does not substantially contain any of menthol, α-terpinene, γ-terpinene, nerol, geraniol, and decanal. When menthol is used as the first fragrance 13a, there is a tendency for the user to provide a metallic-like dislike when the fragrance taster 11 is used. In addition, when α-terpinene, γ-terpinene, nerol, geraniol, or decanal is used as the first fragrance 13a, it is supported in a combustion type when the fragrance taster 11 is stored The spices of the heat source 13 easily disappear.

In this specification, "substantially does not contain a fragrance" means that the step of supporting the fragrance on the corresponding loading site is not performed, but it may include a trace amount of the fragrance transferred from other loading sites.

When the flavor taster 11 does not have the capsule 22 containing the third flavor 22a, but the first flavor 13a carried on the combustion-type heat source 13 and the second flavor 16a carried on the flavor source 16, the second flavor 16a is Contains at least one selected from the group consisting of α-terpinene, γ-terpinene, nerol, geraniol, and decanal. Alternatively, when the flavor absorber 11 includes the first flavor 13a supported on the combustion-type heat source 13 and the capsule 22 containing the third flavor 22a, and also includes the second flavor 16a supported on the flavor source 16, the first 2 The fragrance 16 series can be set to any fragrance, and preferably contains at least one selected from the group consisting of α-terpinene, γ-terpinene, nerol, geraniol, and decanal.

The second fragrance 16a may be a single fragrance compound, or It is a mixture of fragrance compounds. The second fragrance 16a is different from the first fragrance 13a. As the second fragrance 16a, when the above-mentioned fragrance compound is used, the fragrance compound can be stably maintained when the fragrance taster 11 is stored, and when the fragrance taster 11 is used, it is not provided to the user. Like the fragrance. The second fragrance 16a preferably contains at least one selected from the group consisting of nerol and geraniol. Because the vapor pressure of nerol and geraniol is low, the possibility of transferring from the fragrance source 16 to the combustion-type heat source 13 is low.

It is preferable that the second fragrance 16a does not substantially contain anethole, 2-pinene, β-citronellol, agarwood acetate, limonene, anisaldehyde, 4-terpineol, 2-β-pinene, jasmine Any one of ketone, juniper, linalool, 1,8-eucalyptus phenol, phenethyl alcohol, and myristyl ether. As described above, these fragrance compounds can be carried on the combustion-type heat source 13 as the first fragrance 13a. The combustion-type heat source 13 contains activated carbon and has a high retention of fragrance. Moreover, the combustion-type heat source 13 is located at the front end 12B of the holder 12 and can feel the first fragrance 13a carried as an external fragrance. Therefore, it is preferable that the first fragrance 13a contains such fragrance compounds, and the second fragrance 16a preferably contains no such fragrance compounds.

More preferably, the second fragrance 16a does not substantially contain menthol. The highly volatile fragrance system is not suitable as the second fragrance 16a. When a highly volatile fragrance such as menthol is used as the second fragrance 16a, such a fragrance system tends to disappear when the fragrance taster 11 is stored. In addition, when menthol is used as the second fragrance 16a, the menthol will be transferred to the combustion-type heat source 13, and when the flavor inhaler 11 is used, there is a dislike for the user to provide a similar metal The possibility of Huan's fragrance.

When the flavor taster 11 includes the first flavor 13a and the second flavor 16a, and also includes the capsule 22 containing the third flavor 22a, the third flavor 22a can be set to any flavor, preferably including Menthol, α-terpinene, γ-terpinene, nerol, geraniol, and decanal are at least one member of the group. Alternatively, the fragrance taster 11 does not include the second fragrance 16a, but includes the first fragrance 13a and the capsule 22 containing the third fragrance 22a. The third fragrance 22a includes a menthol, α-terpinene, γ -At least one of the group consisting of terpinene, nerol, geraniol, and decanal.

The third fragrance 22a may be a single fragrance compound or a mixture of fragrance compounds. The fragrance compound contained in the third fragrance 22a may be the same as any of the fragrance compounds contained in the first fragrance 13a and the second fragrance 16a, or may be the fragrance contained in the first fragrance 13a and the second fragrance 16a Any one of the compounds is different. In the former case, the third fragrance 22a can supplement that the first fragrance 13a and the second fragrance 16a contain a fragrance compound. In the latter case, the third flavor 22a can change the flavor of the flavor inhaler after squeezing the capsule 22.

Since the third fragrance 22a is contained in the capsule 22, it does not easily volatilize during storage and can be stably maintained. Therefore, the third fragrance 22a can be regarded as the above-mentioned fragrance unsuitable as the first fragrance 13a.

More preferably, the third fragrance 22a contains menthol. Or the third fragrance 22a is more preferably selected from α-terpinene, γ-terpinene, neroli At least one of alcohol, geraniol, and decanal is different from the second fragrance 16a. The third fragrance 22a more preferably contains at least one selected from the group consisting of α-terpinene and γ-terpinene and is different from the second fragrance 16a. Because the vapor pressure of α-terpinene and γ-terpinene is relatively high, it is better to enclose the capsule 22.

The first fragrance 13a is supported on the combustion-type heat source 13 in an amount of, for example, 0.5 to 40 mg, the second fragrance 16a is supported on the fragrance source 16 in an amount of, for example, 0.5 to 40 mg, and the third fragrance 22a is, for example, 2 to The amount of 80mg is contained in the capsule 22.

In this specification, the expressions that "the second fragrance system is different from the first fragrance" and "the third fragrance system is different from the second fragrance" mean that the fragrance contains at least one fragrance compound and the one contains at least one fragrance compound The other spices are not exactly the same. For example, the second fragrance composed of fragrance compounds A and C is different from the first fragrance composed of fragrance compounds A and B.

As described above, in the present invention, in addition to the fragrance source 16, the combustion-type heat source 13 is also used as the fragrance supporting portion. The combustion-type heat source 13 contains activated carbon and has the advantage of high retention of the first fragrance 13a. In addition, the combustion-type heat source 13 is located at the front end 12B of the holder 12, and when the flavor inhaler 11 is held by the user's lips, it is arranged close to the user's nose. Therefore, the combustion-type heat source 13 has an advantage that the fragrance (external fragrance) can be efficiently transmitted to the user's nose even in a small amount of the first fragrance 13a. Therefore, according to the present invention, it is possible to provide a flavor taster by incorporating flavors according to the characteristics of flavors At the most suitable place to add the flavor inhaler, the enhanced aroma that the user likes appears.

The flavor inhaler 11 uses the combustion-type heat source 13 loaded with the first flavor 13a to warm the flavor source 16 loaded with the second flavor 16a and to taste from the mouth side so that the user can taste Flavors derived from the first flavor 13a, the second flavor 16a, and the flavor source 16. In addition, the fragrance taster 11 squeezes the capsule 22 with a finger to release the third fragrance 22a contained in the capsule 22, thereby enhancing the fragrance or changing the fragrance. Moreover, when the flavor taster 11 is taken out of the package, the user can feel the aroma (external flavor) emitted from the first flavor 13a. Moreover, the user can feel the aroma (external fragrance) emitted from the first fragrance 13a even before the ignition type heat source 13 is ignited with the lips holding the fragrance taster 11.

Hereinafter, each constituent element of the flavor taster 11 will be described.

The holder 12 includes a first portion 23 that holds the combustion-type heat source 13 and the cup 17; and a second portion 24 that connects the first portion 23 and the filter portion 21 on the suction port end 12A side. The first part 23 is a paper tube formed by rolling a paper roll into a cylindrical shape. The second part 24 is paper for outer paper (tipping paper). The outer paper is generally used as a filter-coated cigarette (paper cigarette) to cover the filter portion, and the outer paper is rolled into a cylindrical shape And the shaper. The aluminum bonding paper 18 is formed by bonding aluminum to paper, and its heat resistance and thermal conductivity are improved compared to ordinary paper. With the aluminum bonding paper 18, even when the combustion-type heat source 13 is ignited, the first portion 23 (paper tube) of the holder 12 is not burned. Central axis C of the holding body 12 It coincides with the central axis C of the combustion-type heat source 13.

The fragrance source 16 is disposed downstream of the combustion-type heat source 13 at a position adjacent to the combustion-type heat source 13. The flavor source 16 is composed of particles formed from tobacco extract and the like. In addition, the flavor source 16 is not limited by particles, and the tobacco leaf itself can also be used. That is, as the flavor source 16, it is also possible to use tobacco raw materials such as finely cut shredded tobacco used in cigarettes, granular tobacco used in snuff, roll tobacco, and formed tobacco. As the scent source 16, a person carrying a scent on a carrier of a porous material or a non-porous material may also be used. The roll-tobacco system is obtained by forming sheet-shaped regenerated tobacco into a roll shape and has a flow path inside. In addition, shaped tobacco is obtained by molding granular tobacco using a mold. Using the tobacco raw material or carrier as the flavor source 16, the above-mentioned second flavor 16a is supported. The second fragrance 16a can be carried on the fragrance source 16 by spraying or applying the liquid containing the second fragrance 16a to the fragrance source 16, or by dipping the liquid containing the second fragrance 16a in the fragrance source 16 . The fragrance source 16 is generally an acidic pH, for example having a pH of 4 to 7.

For the analysis of the pH of the fragrance source 16, for example, the following method can be used. First, 400 mg of fragrance source 16 was collected, 4 mL of pure water was added, and vibration extraction was performed for 60 minutes. In a laboratory controlled at a room temperature of 22°C, the extract is placed in a closed container to adjust the temperature until it reaches room temperature. After the adjustment, the lid was opened, and the glass electrode of the pH meter (manufactured by METTLER TOLEDO: Seveneasy S20) was immersed in the trap solution to start the measurement. The pH meter is calibrated in advance using pH meter calibration solutions of pH 4.01, 6.87, and 9.21. Will change the output power of the sensor The temperature stabilized within 0.1 mV within 5 seconds as the pH of the extraction solution (fragrance source 16). In addition, this method of measuring the pH of the fragrance source 16 is only one example, and of course other methods can be used.

The cup 17 is formed into a bottomed cylindrical shape using a metal material. The bottom 25 of the cup 17 is formed with a plurality of openings 25A. When the user tastes, the tobacco flavor passes through the opening 25A together with the air and is attracted to the downstream side of the holder 12. The edge portion 26 of the cup 17 is bent outward in the radial direction of the holder 12 and can be caught by the front ends of the holder 12 and the aluminum bonding paper 18. The inner peripheral surface of the cup 17 is provided with a segment portion 17A that abuts on the base end surface 29 of the combustion-type heat source 13. The inner peripheral surface of the cup 17 can accommodate the body portion 27 of the combustion-type heat source 13 together with the segment 17A, while keeping the combustion-type heat source 13 from falling off.

The cup 17 may also be a cup made of paper. The cup made of paper, for example, has the same structure as the metal cup described above. Paper cups can be manufactured using well-known techniques for pulp injection molding. Specifically, a cup made of paper can be produced by kneading a raw material containing pulp, a binder, and water, injecting it into a heated mold, and drying and solidifying it. From the viewpoint of flavor, it is preferable to use CMC (carboxymethyl cellulose) or CMC-Na (sodium carboxymethyl cellulose) as a binder. Compared to metal cups, paper cups have the characteristic that the heat conduction rate to the flavor source 16 is slower. In addition, the paper cup system can reduce the weight of the flavor taster or reduce the manufacturing cost.

The filter unit 21 is composed of a filter that is generally used in cigarettes. The same applies to capsule 22, which is commonly used in cigarette flavors The capsule contains the liquid containing the third fragrance 22a inside. The third fragrance 22a includes, for example, at least one selected from the group consisting of menthol, α-terpinene, γ-terpinene, nerol, geraniol, and decanal. As described above, the menthol system produces an unpleasant scent when it is loaded on the combustion-type heat source 13, or it is volatilized and transferred to the combustion-type heat source 13 when it is loaded on the fragrance source 16, causing dislike The possibility of scent. Therefore, the menthol system is preferably enclosed in the capsule 22. As the solvent of the third fragrance 22a, a solvent capable of dissolving the fragrance can be used, for example, medium chain fatty acid triglyceride (MCT) can be used.

The filter unit 21 can be formed using various types of fillers. In the present embodiment, the filter portion 21 is composed of a filler material of cellulose-based semi-synthetic fibers such as cellulose acetate, but the filler material is not limited to this. For the filler material, vegetable fibers such as cotton, hemp, manila hemp (Musa textilis), coconut, rushes, animal fibers such as wool, cashmere wool, cellulose-based regenerated fibers such as rayon cashmere wool, and nylon can be used , Polyester, acrylic resin, polyethylene, polypropylene and other synthetic fibers or a combination of these. The constituent elements of the filter unit 21 may be a filler composed of the cellulose acetate fiber, a charcoal filter containing charcoal (charcoal), or a filter in which particulate matter other than charcoal is added. In addition, the filter unit 21 may have a multi-segment structure in which two or more different types of segments are connected in the axial direction.

By squeezing the capsule 2 contained in the filter part 21, the aroma of mainstream smoke can be enhanced or changed. Therefore, it is possible to provide a more attractive product that meets the preferences of the user. Also, can If the fragrance is decomposed or volatilized by heat when it is loaded on the combustion-type heat source 13, or the fragrance is volatilized when it is loaded on the fragrance source 16, the fragrance capsule is kept. Therefore, it can be carried in the combustion-type heat source 13, or in the fragrance source 16, or enclosed in the capsule 22 according to the characteristics of the fragrance, and the freedom of the fragrance design of the product can be further improved (expanding the choice of fragrance) .

As shown in Figure 2, the combustion-type heat source 13 (carbon heat source) can be obtained by combining activated carbon derived from plant sources, non-combustible additives (such as calcium carbonate), binders (organic binders or inorganic binders, such as carboxyl Combustion materials of a mixture of sodium methylcellulose) and water, etc., are formed by integral molding by methods such as ingot casting and die casting. The combustion-type heat source 13 contains a mixture of activated carbon and binder, such as honeycomb coal. The combustion-type heat source 13 is preferably contained in activated carbon, so-called highly activated carbon. The term “highly activated carbon” means that among activated carbons, the specific surface area measured by the Brunauer-Emmett-Teller method (BET method), which is standardized according to ISO9277:2010 and JISZ8830:2013, is 1300 m ² /g, for example. The above. The activated carbon used in the combustion-type heat source 13 has a porous structure including a plurality of macropores and a plurality of micropores.

The BET specific surface area of the activated carbon contained in the combustion-type heat source 13 is, for example, 1300 m ² /g or more. The BET specific surface area of the activated carbon contained in the better combustion-type heat source 13 is, for example, 2000 m ² /g or more and 2500 m ² /g or less. BET of the activated carbon in the optimal combustion type heat source 13 comprising, for example, specific surface area and 2300m ² 2050m ² / g or more / g or less. Therefore, the activated carbon used in the combustion-type heat source 13 is classified as highly activated carbon, and the amount of macropores and micropores is larger than that of ordinary activated carbon. In other words, the activated carbon used in the combustion-type heat source 13 has a higher activation degree than ordinary activated carbon. That is, the activated carbon used in the combustion-type heat source 13 can be obtained by removing the volatile impurities by heating the carbon material or the like and making the activation degree higher than that of ordinary activated carbon.

The BET specific surface area of the activated carbon contained in the combustion-type heat source 13 is substantially the same as the BET specific surface area of the activated carbon used as a material for manufacturing the combustion-type heat source 13. The combustion-type heat source 13 is different from the fragrance source 16 and is generally an alkaline pH, for example, having a pH of 8 to 11.

The combustion-type heat source 13 has a porous structure including a large number of macropores and micropores of a large amount of highly activated carbon, so that the first fragrance 13a can be adsorbed and a large amount of positions capable of maintaining the first fragrance 13a can be maintained stably for a long period of time. Therefore, even after storage, the combustion-type heat source 13 having a high residual rate of the first fragrance 13a and the flavor taster 11 provided with the combustion-type heat source 13 can be realized. Therefore, it is possible to provide attractive products that meet the user's taste. In addition, according to the above-mentioned configuration, the porous structure of highly activated carbon can improve the ignitability and can realize the flavor inhaler 11 that is easy to ignite. In addition, the porous structure of the highly activated carbon can improve the flammability of the combustion-type heat source 13 and can continue stable combustion in the combustion-type heat source 13.

The combustion-type heat source 13 can contain activated carbon in an amount ranging from 10% to 99% by weight. Here, from the viewpoint of sufficient heat supply, prevention of ash fall and other combustion characteristics, the concentration of activated carbon contained in the combustion-type heat source 13 is, for example, 30% by weight or more and 60% by weight or less Better. More preferably, the activated carbon concentration contained in the combustion-type heat source 13 is 30% by weight or more and 45% by weight or less.

When the amount of carbon contained in the combustion-type heat source 13 is too large, the generated heat tends to become too large, and when the amount of carbon contained in the combustion-type heat source 13 is too small, there is a tendency that sufficient heat cannot be obtained. As described above, when the concentration of the activated carbon contained in the combustion-type heat source 13 is 30% by weight or more, it is possible to raise sufficient heat to the fragrance source 16. Therefore, the fragrance source 16 can be heated at an appropriate temperature, and the components can be efficiently taken out from the fragrance source 16 to reach the mouth of the user. In addition, when the concentration of the activated carbon contained in the combustion-type heat source 13 is 60% by weight or less, it is possible to reduce the ash scattering associated with combustion and the amount of carbon monoxide contained in the mainstream smoke.

As the organic binder, for example, CMC (carboxymethyl cellulose), CMC-Na (carboxymethyl cellulose sodium), alginate, ethylene vinyl acetate (EVA), polyvinyl alcohol (PVA), poly A mixture of at least one of vinyl acetate (PVAc) and sugar.

In addition, as the inorganic binder, for example, a mineral-based binder such as refined bentonite, or a silica-based binder such as colloidal silica, water glass, calcium silicate, or the like can be used.

For example, from the viewpoint of fragrance, the above-mentioned binder preferably contains 1 to 10% by weight of CMC or CMC-Na, and preferably 1 to 8% by weight of CMC or CMC-Na.

In addition, as a non-combustible additive, for example, a carbonate or an oxide composed of sodium, potassium, calcium, magnesium, silicon, or the like can be used. In addition, the combustion-type heat source 13 can contain 40% to 89% by weight of non-combustible additives.

Here, calcium carbonate is used as the non-combustible additive, and the combustion-type heat source 13 preferably contains 40 to 60% by weight of the non-combustible additive.

For the purpose of improving the combustion characteristics, the combustion-type heat source 13 may contain an alkali metal salt such as sodium chloride in a proportion of 1% by weight or less.

As shown in Figs. 1 and 2, the combustion-type heat source 13 is formed in a cylindrical shape. The combustion-type heat source 13 has: a body portion 27 that is held in the holder 12; a protrusion 14 (exposed portion) that protrudes from the front end 12B of the holder 12; a front end surface 28 that is provided on the protrusion 14; the base end surface 29, which is opposed to the front end surface 28; the air passage 31, which is used to supply air to the inside of the holder 12, the outer peripheral surface 32, which is adjacent to the front end surface 28; and the groove 33, which is裝于 PROJECT 14. The ventilation path 31 is provided along the central axis C of the combustion-type heat source 13 and is provided so as to penetrate the combustion-type heat source 13. The air passage 31 connects the front end surface 28 and the base end surface 29. The ventilation path 31 is provided so as to straddle both the body portion 27 and the protruding portion 14. The portion on the front end surface 28 side of the air passage 31 is integrated with the groove 33. The outer peripheral surface 32 is positioned around the protruding portion 14 and forms the periphery of the combustion-type heat source 13. The protruding portion 14 (exposed portion) also protrudes from the front end of the cup 17.

The combustion-type heat source 13 has a first chamfered portion 34 formed between the front end surface 28 and the outer peripheral surface 32, and a second chamfered portion 35 formed between the base end surface 29 and the outer peripheral surface 32. With the first chamfered portion 34 and the second chamfered portion 35, cracks and defects are less likely to occur at the corners of the combustion-type heat source 13.

Viewed from the front end surface 28 side, the entire groove portion 33 is formed into a "ten" shape. The shape of the groove 33 is not limited by the "ten" shape. The number of grooves 33 is arbitrary. The shape of the groove 33 as a whole can be any shape. For example, a plurality of grooves 33 may extend radially toward the outer peripheral surface 32 with the air passage 31 as the center. At this time, the angle between the adjacent groove portions 33 can be appropriately set within a range of 5° or more and 95° or less, for example. In addition, in the present embodiment, the groove portion 33 can be formed by being recessed from these so as to straddle the front end surface 28 and the outer peripheral surface 32. The groove 33 can be provided so as to communicate with the air passage 31. The depth (length) of the groove portion 33 in the direction of the central axis C of the combustion-type heat source 13 is preferably 1/3 to 1/5 of the total length relative to the direction of the central axis C.

The combustion-type heat source 13 is preferably formed in the following dimensions. The total length of the combustion-type heat source 13 (the length of the combustion-type heat source 13 in the direction of the central axis C) is, for example, within a range of 5 mm or more and 30 mm or less, preferably within a range of 10 mm or more and 20 mm or less. Among them, the length of the protruding portion 14 in the direction of the central axis C is, for example, appropriately set within a range of 5 mm or more and 15 mm or less, preferably within a range of 5 mm or more and 10 mm or less. Therefore, the length of the protruding portion 14 is set within a range of 2/3 or more and 4/5 or less of the total length of the combustion-type heat source 13, for example. In addition, the length of the portion where the combustion-type heat source 13 is inserted into the cup 17 (the length in the direction of the central axis C of the body portion 27, the insertion length) is in the range of 2 mm or more and 10 mm or less, preferably 2 mm or more and Set appropriately within the range of 5 mm or less.

The diameter of the combustion-type heat source 13 (square crossing the central axis C The length of the combustion-type heat source 13 is appropriately set within a range of, for example, 3 mm or more and 15 mm or less. The depth (length) of the groove 33 in the direction of the central axis C is, for example, within a range of 1 mm or more and 5 mm or less, preferably within a range of 2 mm or more and 4 mm or less. The width (inner diameter) W of the groove 33 is appropriately set within a range of 0.5 mm or more and 1 mm or less, for example.

The groove 33 may be recessed from at least one of the front end surface 28 and the outer peripheral surface 32. For example, the groove portion 33 may be recessed from the front end surface 28 to communicate with the air passage 31, and may be provided so as not to open on the outer peripheral surface 32 side. Similarly, for example, the groove portion 33 may be recessed from the outer peripheral surface 32 to communicate with the air passage 31, and may be disposed so as not to open on the front end surface 28 side. In the latter example, it is preferable that the ventilation path 31 extends up to the front end surface 28 and is opened to the outside at the front end surface 28.

In addition, the combustion-type heat source 13 may not have the ventilation path 31. At this time, it is preferable to form a plurality of small holes for ventilation in the holder 12 (the first portion 23). When the user tastes, the air is supplied into the holder 12 and the fragrance source 16 located in the holder 12 through the small holes.

In the present embodiment, the first fragrance 13a is supported on the combustion-type heat source 13.

The combustion-type heat source 13 has a protruding portion 14 protruding from the front end 12B of the holder 12, and the first fragrance 13a is preferably carried on the protruding portion 14. With this configuration, the first fragrance 13a carried on the protruding portion 14 is not only introduced into the mainstream smoke and exerts the effect of the internal flavor, but also directly reaches the user's nose without being introduced into the mainstream smoke to exert the external The role of fragrance. In particular, the protruding portion 14 of the combustion-type heat source 13 is arranged close to the nose of the user when the lips are held by the lips, so even if a small amount of the first fragrance 13a, the fragrance (external fragrance) It can reach the user's nose efficiently.

More specifically, the first fragrance 13a is supported on the front end surface 28 of the combustion-type heat source 13, the first chamfered portion 34, the inner peripheral surface of the groove 33, the outer peripheral surface 32, and the air passage 31 (inner periphery of the air passage 31 Face). In addition, it is preferable that the first fragrance 13a is not substantially supported on the base end surface 29 of the combustion-type heat source 13 and the second chamfered portion 35. However, the first fragrance 13a volatilized or diffused from the front end surface 28 and the first chamfered portion 34 may be attracted and held by the base end surface 29 and the second chamfered portion 35.

In one aspect, the first fragrance 13a is supported on the front end surface 28, for example. With this configuration, the first fragrance 13a can be carried on the front end surface 28 less likely to be held by the user, even if the user holds the outer peripheral surface of the combustion-type heat source 13 before the flavor inhaler 11 is tasted In the case of 32, it is also possible to prevent the defect that the first fragrance 13a is transferred by the user's finger or the like.

When the first fragrance 13a is supported on the front end surface 28 and on the inner peripheral surface of the first chamfered portion 34 and the groove 33, the amount of the first fragrance 13a supported can be along the central axis C And change. That is, in the present embodiment, the loading amount of the first fragrance 13a is the largest when the front end surface 28 and the first chamfered portion 34 are used. At this time, the amount of the first fragrance 13a carried inside the combustion-type heat source 13 may not be uniform. The first fragrance 13a may be carried in the combustion-type heat source 13 so as to gradually decrease the amount of the first fragrance 13a from the front end surface 28 toward the base end surface 29.

Various methods can be used to support the first fragrance 13a on the front end surface 28 of the combustion-type heat source 13. For example, as shown in FIG. 3, the nozzle may be arranged to face the front end surface 28, and the nozzle is shown by an arrow as shown in FIG. 3, so that the liquid droplet containing the first fragrance 13a is directed from the nozzle toward the front end surface 28 and the first The chamfered portion 34 is discharged (dropped), and the liquid containing the first fragrance 13a adheres to the front end surface 28 and the first chamfered portion 34. The liquid containing the first fragrance 13a may be discharged to the entire front end surface 28, or may be partially discharged to a part of the front end surface 28. For example, when it is not desired to attach the first fragrance 13a to the portion corresponding to the ventilation passage 31 (the ventilation passage 31 and the wall portion defining the outer edge of the ventilation passage 31), the droplet containing the liquid of the first fragrance 13a is discharged from the corresponding ventilation The position where the road 31 is partially detached. By the liquid system penetrating from the front end surface 28 into the combustion-type heat source 13, the first fragrance 13 a is supported near the front end surface 28. Or, by holding the position of the base end surface 29 side of the outer peripheral surface 32 of the combustion-type heat source 13, the front end surface 28 of the combustion-type heat source 13, the first chamfered portion 34, and the groove portion 33 are immersed in the liquid containing the first fragrance 13a At a predetermined time, the first fragrance 13a can be carried on the front end surface 28, the first chamfered portion 34, and the groove portion 33. Furthermore, by pressing the front end surface 28 against the elastic porous body (for example, sponge) containing the first perfume 13a, the first perfume 13a can also be loaded near the front end surface 28 and the first chamfered portion 34. In addition, the liquid droplets containing the first fragrance 13a can be discharged by an inkjet method.

In another aspect, the first fragrance 13a is supported on the outer peripheral surface 32, for example. As shown in FIG. 2, the first fragrance 13a is supported on a plurality of ring-shaped supporting portions 42, and the plurality of ring-shaped supporting portions 42 is attached to the central axis C The directions are formed on the outer peripheral surface 32 at predetermined intervals. The plurality of supporting portions 42 have a predetermined width in the direction of the central axis C and are formed in a band shape. The shape of the supporting portion 42 is not limited by a plurality of rings. The load-bearing portion 42 may also be formed into a band shape (annular shape) with a wide width. In addition, the shape of the supporting portion 42 is not limited to a ring shape. For example, a plurality of belt-shaped supporting portions 42 extending parallel to the central axis C and linearly may be provided. In this case, the supporting portion 42 is preferably arranged at a certain interval from the other adjacent supporting portion 42. At this time, the plurality of load portions 42 are arranged around the central axis C with a certain interval.

The plurality of load-bearing portions 42 are preferably provided closer to the base end surface 29 side (the suction port end 12A side) than the front end surface 28 and the groove portion 33. Furthermore, it is preferable that the plurality of load-bearing portions 42 are provided on the base end surface 29 side (at the suction port end 12A side) 3 mm or more from the front end surface 28. Preferably, the plurality of load-bearing portions 42 are preferably provided on the base end surface 29 side (at the suction port end 12A side) 5 mm or more from the front end surface 28. With the arrangement of these supporting portions 42, even when the user ignites in the vicinity of the front end surface 28, the first fragrance 13 a can be arranged at a position where it will not be exposed to flame due to ignition. Such an arrangement is particularly useful when the loading portion 42 carries the first fragrance 13a that is less likely to lose aroma due to ignition. In addition, the shape of the supporting portion 42 is not limited by a plurality of rings. The load-bearing part 42 may be formed into a single belt shape (annular shape) with a wide width.

The amount of the first fragrance 13a carried on the combustion-type heat source 13 may also vary along the radial direction of the combustion-type heat source 13. That is, in the present embodiment, the loading amount of the first fragrance 13a is the largest on the outer peripheral surface 32. At this time, the amount of the first fragrance 13a carried may not be uniform within the combustion-type heat source 13. The first spice 13a may face from the outer peripheral surface 32 It is carried in the combustion-type heat source 13 so as to gradually decrease the amount of the first fragrance 13a toward the central axis.

Various methods can be used for the method of supporting the first fragrance 13a on the outer peripheral surface 32 of the combustion-type heat source 13. For example, a plurality of tiny rollers partially immersed in the liquid containing the first fragrance 13a are arranged in series with each other. The direction of rotation of each roller is a direction crossing the direction when a plurality of rollers are arranged in series. The combustion-type heat source 13 is arranged so as to straddle the plurality of rollers thus constituted, and the combustion-type heat source 13 is rotated on the plurality of rollers. With this, the first fragrance 13a can be transferred (applied) such that a plurality of belt-shaped (ring-shaped) supporting portions 42 are formed on the outer peripheral surface 32. Alternatively, the first fragrance 13a can be supported on the outer peripheral surface 32 by continuously applying the relatively high viscosity liquid containing the first fragrance 13a from the nozzle close to the outer peripheral surface 32 to the rotating combustion-type heat source 13. In addition, the method of applying the first fragrance 13a to the outer peripheral surface 32 and carrying the first fragrance 13a on the outer peripheral surface 32 can employ various methods such as an inkjet method.

In another aspect, the first fragrance 13a is carried on the ventilation path 31, for example. The first fragrance 13a is carried on the ventilation path 31 by, for example, the following method. That is, the nozzle is arranged so as to face the air passage 31, and as shown by the dashed arrow in FIG. 3, the liquid droplet containing the first fragrance 13a is discharged (dropped) from the nozzle. Thereby, by adhering the liquid containing the first fragrance 13a to the inner peripheral surface of the air passage 31 and allowing the liquid to penetrate into the combustion-type heat source 13, the first fragrance 13a can be supported near the inner peripheral surface of the air passage 31 .

Also, as mentioned above, regarding the liquid containing the first fragrance 13a The discharge (coating) of liquid droplets is mainly to explain that they are individually attached according to the application position, but the application of fragrance can also be performed at once by the inkjet method.

The function of the flavor taster 11 of this embodiment will be described. As described above, the user can feel the scent (external scent) emitted by the first fragrance 13a carried on the burned heat source 13 when the fragrance inhaler 11 is taken out of the package before the taste of the fragrance taster 11 . In addition, the user can feel the fragrance (external fragrance) emitted from the first fragrance 13a before and after the combustion-type heat source 13 ignites with the lips holding the suction port 36 of the holding body 12.

The user ignites near the front end surface 28 of the combustion-type heat source 13, and if the user starts to taste, the combustion-type heat source 13 will heat up to a predetermined temperature (for example, 250°C to 900°C) by the heat from the combustion-type heat source 13 And heating the fragrance source 16. As a result, the second fragrance 16a contained in the fragrance source 16 is diffused, passes through the filter portion 21, and reaches the mouth of the user. With this, the user can taste the fragrant flavor from the second fragrance 16a. At this time, the first fragrance 13a carried on the front end surface 28 is introduced into the holder 12 together with the surrounding air through the air passage 31, and the components released from the second fragrance 16a in the cup 17 are mutually The blending reaches the user's mouth through the filter section 21. Therefore, the user can feel the first fragrance 13a carried on the front end surface 28 through the form of the inner fragrance contained in the mainstream smoke. In addition, the user can squeeze the capsule 22 with his fingers as needed, whereby the third flavor 22a contained in the capsule 22 can be released, and the aroma of mainstream smoke can be enhanced or changed. In addition, the term "internal scent" here refers to Afterwards, the fragrance component that is transferred to the nose (nasal cavity) can be felt. The external fragrance refers to a fragrance that can be felt without passing through the fragrance component of the nose (nasal cavity) through the mouth (oral cavity).

The user performs tasting for a predetermined period of time. When the combustion-type heat source 13 burns out or when the odor from the fragrance source 16 disappears, the tasting ends. At this time, since the ash of the combustion-type heat source 13 does not fall to the ground and is held at the front end of the holding body 12, the load on the surrounding environment is small. In addition, compared with the previous paper cigarette (cigarette), since the smoke generated from the flavor taster 11 is significantly less, the load on the surrounding environment is smaller.

The flavor inhaler 11 is not limited to the above-mentioned embodiment, and in the implementation stage, the constituent elements can be deformed and embodied without departing from the gist thereof. For example, the shape of the holding body 12 is not cylindrical, and for example, it may of course have a cylindrical shape with a square shape, a cylindrical shape with an elliptical cross section, or a cylindrical shape with other polygonal cross sections (hexagonal shape, octagonal shape, etc.).

For example, with time as the horizontal axis and pressure drop as the vertical axis, the pressure drop curve in the holding body 12 of the flavor inhaler 11 becomes a so-called bell shape during one puff (puff) suction ( (The middle point of the suction time is the maximum pressure drop). As shown in the table above, the interval between the start of smoking is 30 seconds. The smoking time (Duration) is 2 seconds. Therefore, under this smoking condition, the smoking time and the non-smoking time are alternately repeated in such a manner that the smoking time is 2 seconds → the non-smoking time 28 seconds → the smoking time 2 seconds → the non-smoking time 28 seconds. In addition, the volume of smoke inhaled in one smoking was 55 ml. System of pumping times 15 times (12 times + 3 times the red heat of the combustion-type heat source is confirmed).

Smoking is performed under such smoking conditions and the Cambridge filter 63 is used to capture the smoke. The Cambridge filter 63 is added to methanol containing a standard solution, and the Cambridge filter 63 is pulverized, shaken, and filtered to obtain a sample liquid. The sample solution was analyzed by GC/MS. By this, the quantitative value of the fragrance collected by the Cambridge filter 63 is obtained.

Similarly, for the smoke passing through the Cambridge filter 63, an air collector 65 filled with a standard liquid and added with methanol is also used for trapping. The sample liquid obtained from the air collector 65 was analyzed by GC/MS. With this, the quantitative value of the fragrance collected by the air collector 65 is obtained.

In addition, the smoke attached to the inner wall of the tube 66 is also recovered according to the following procedure. First, after the tube 66 is broken, it is added to methanol containing a standard solution. This was shaken and filtered to obtain a sample liquid. The sample solution was analyzed using GC/MS. By this, the quantitative value of the fragrance adhering to the inner wall of the tube 66 is obtained. GC/MS was performed under the conditions shown in Table 3 below.

The sum of the quantitative value of the fragrance collected by the Cambridge filter 63, the quantitative value of the fragrance collected by the air collector 65, and the quantitative value of the fragrance attached to the inner wall of the tube 66 is used as the fragrance transferred to the mainstream smoke the weight of. The transfer rate of flavor to mainstream smoke can be calculated according to the following mathematical formula.

(Transfer rate) (%) = ((quantity value of the fragrance captured by the Cambridge filter 63) + (quantity value of the fragrance captured by the air collector 65) + (perfume attached to the inner wall of the tube 66 Quantitative value))/(total weight of spices in combustion-type heat source 13)... Equation (1)

As an example, the result of the transfer rate calculated by this method when using anethole as a spice is shown.

The total weight of the fragrance loaded on the combustion-type heat source 13 is 3075 μg (corresponding to the denominator of formula (1)). On the other hand, the total weight of flavor transferred to mainstream smoke was 42.77 μg (corresponding to the molecule of formula (1)). Therefore, when anethole is used as a spice, the transfer rate of anethole to mainstream smoke is 1.39% according to equation (1).

This result confirms that the first fragrance carried on the combustion-type heat source is transferred to mainstream smoke, and shows that it interacts with the second fragrance carried on the fragrance source and the third fragrance contained in the fragrance capsule, which can help The fragrance of the user.

Example 3: Example of using menthol as the first fragrance

The combustion-type heat source 13 was manufactured in the same manner as the method described in Example 1. Thereby, a combustion-type heat source 13 having the form shown in FIG. 2 and containing activated carbon having a BET specific surface area of 2050 m ² /g and having an activated carbon concentration of 39.7% by weight was manufactured.

According to the same method as described in Example 1, menthol was carried on the produced combustion-type heat source 13. Using the combustion-type heat source 13 carrying menthol, the flavor inhaler 11 shown in FIG. 1 (comparative example) was manufactured.

The present inventors felt the unpleasant scent similar to metal when savouring the flavor inhaler 11 (comparative example).

Example 4: Functional evaluation of the first fragrance

[Manufacture of combustion type heat source]

The combustion-type heat source 13 was manufactured in the same manner as the method described in Example 1. Thereby, a combustion-type heat source 13 having the form shown in FIG. 2 and containing activated carbon having a BET specific surface area of 2050 m ² /g and having an activated carbon concentration of 39.7% by weight was manufactured.

According to the same method as described in Example 1, anethole was carried on the produced combustion-type heat source 13. The flavor inhaler 11 shown in FIG. 1 is manufactured using a combustion-type heat source 13 carrying spices. Geraniol is used as the second fragrance, and menthol is used as the third fragrance.

The present inventors can feel the fragrance (external fragrance) emitted from the fragrance carried on the combustion-type heat source 13 before tasting. In addition, the inventors of the present invention can feel the scent (external scent) emitted from the fragrance before and after the combustion heat source 13 is ignited with the lips holding the fragrance taster 11.

When tasting the flavor inhaler 11, you can taste the first flavor loaded on the combustion-type heat source 13, the second flavor loaded on the flavor source 16, and the flavor derived from the flavor source 16 without feeling unpleasant fragrance. also. Squeezing the capsule 22 with your fingers can release the third flavor contained in the capsule 22 and change the flavor of the mainstream smoke.
