Description

TECHNICAL FIELD The present invention relates to an aroma cartridge that is attached to an inhaler having an electric heating means and that can generate an aerosol containing an aroma component by being heated by the electric heating means.

The fragrance cartridge is attached to an inhaler having an electric heating means, and is heated by the electric heating means to generate an aerosol containing an aromatic component.

By the way, the fragrance cartridge can take various forms depending on the specifications of the suction device. For example, fragrance cartridges are often formed in a cylindrical shape, but in a suction device in which the electrical heating means is formed in the shape of a blade or a pin, the fragrance substrate that generates an aerosol by heating is electrically heated. The diameter of the fragrance cartridge is set so that the means can be inserted.

On the other hand, in a suction device in which the electric heating means is formed in a cylindrical shape or the like so as to be able to heat the outer peripheral surface of the fragrance cartridge, there is no need to insert the electric heating means through the fragrance base material. It is possible to set the diameter to be smaller than that of the fragrance cartridge used in the suction device which is formed in a shape or the like.

Users desire that the aroma cartridge has a constant smoking feeling and a constant smoking time regardless of its form. Therefore, it is preferable that the amount of the aerosol-generating fragrance base material to be filled in the fragrance cartridge is at least a certain amount regardless of the form of the fragrance cartridge.

When the length of the fragrance base material filled in the fragrance cartridge in the axial direction becomes longer, the ventilation resistance in the aerosol flow path increases, which makes it difficult to obtain sufficient aerosol suitable for smoking.

Also, if the amount of the aromatic base material is reduced in order to reduce the ventilation resistance in the aerosol flow path, the aromatic base material may move to one end side or the other end side of the cartridge. When the fragrance base material moves to such a position, when the fragrance cartridge is attached to the suction device, the fragrance base material is not arranged in the region (heating region) that can be heated by the electric heating means of the suction device. , there is a problem that it will not be able to generate aerosol properly.

In other words, the ventilation resistance of the aromatic base material in the axial direction of the cover can be reduced according to the distance, compared to the case where the aromatic base material is arranged over the entire heating area. Further, by arranging the aromatic base material intermittently in the axial direction of the cover, it is possible to alternately arrange regions with low airflow resistance and regions with high airflow resistance. Therefore, even if the flow velocity of the gas containing the aerosol is slowed down in the region of high ventilation resistance, it is increased in the subsequent region of low ventilation resistance. As a result, the ventilation resistance in the axial direction of the cover can be reduced more than when the fragrance base materials are collectively arranged at one position. Therefore, it is possible to improve the ease of inhaling the aerosol generated from the aromatic base material. In addition, since the aerosol and air can be mixed in an appropriate distribution, it is possible to improve the flavor.

According to such an aspect, it becomes possible to hold the aromatic base material arranged closest to the proximal end of the cover at a predetermined position in the cover by the regulating member. As a result, when the fragrance cartridge is attached to the suction device, the fragrance base material can be held at a position suitable for heating by the electric heating means.

In the aroma cartridge of the present invention, the partition wall includes a cotton-like member, a porous member, a honeycomb structure, a mesh structure, and a through hole formed through the cover from one end to the other end along the axial direction. It is preferable to consist of at least one selected from the paper winding members having.

In the fragrance cartridge of the present invention, it is preferable that the fragrance base materials are dispersed in the heating area of the electric heating means while attached to the suction device.

The partition wall 40 may have air permeability suitable for smoking, for example, at least the same air permeability as the filter 30 .

In this embodiment, the partition wall 40 is formed in a hollow cylindrical shape having a through hole 41 penetrating from one end to the other end. may be configured. The partition wall 40 is preferably made of a material having heat resistance to the temperature range (for example, 180 to 400° C.) heated by the electric heating means of the heated cigarette. Materials having such heat resistance include paper, resin, rubber, wood, metal, and ceramics. As the partition wall 40, for example, a rolled paper member formed into a cylindrical shape having a spiral gap when viewed from the end face can be used by rolling a sheet of paper into a spiral shape from the end.

If the partition wall 40 has a structure with air permeability from the distal end side to the proximal end side of the cover 10 and has a function of restricting the movement of the fragrance base material 20 disposed on the distal end side toward the proximal end side, that The shape is not limited. The partition wall 40 is preferably made of at least one selected from, for example, a cotton-like member, a porous member, a honeycomb structure, a mesh structure, and the aforementioned rolled member. It is sufficient that the fragrance base materials 20 are arranged at predetermined intervals in the axial direction of the cover 10, and the partition wall 40 does not necessarily need to be provided in the fragrance cartridge 100. FIG. For example, if each fragrance base material 20 can be fixed to the inner surface of the cover 10 by the tackiness of the material itself, an adhesive, or the like, the partition 40 is not necessarily required.

As shown in FIG. 4, the heat-not-burn cigarette 50 has an insertion hole 51 into which the aroma cartridge 100 can be inserted. An electric heating means 52 capable of raising the temperature of the inner peripheral surface of the insertion hole 51 is provided inside the heating cigarette 50 .

The electric heating means 52 includes, for example, an electric resistance material, and can be heated to 150-400° C. by being powered. Electrically resistive materials include, but are not limited to, semiconductors such as doped ceramics, "conductive" ceramics (e.g., molybdenum disilicide), carbon, graphite, metals, metal alloys, and ceramic and metal materials. Composite materials made may be mentioned.

As an alternative to electrically resistive materials, the electrical heating means 52 can include infrared heating elements, optical sources, or induction heating elements.

In the insertion hole 51, the area that can be heated to 150 to 400° C. by the electric heating means 52 is defined as a heating area R1, and the other area is defined as a non-heating area R2.

The aroma cartridge 100 is attached to the heated cigarette 50 by being inserted through the insertion hole 51 of the heated cigarette 50 . When the aroma cartridge 100 is attached to the heating type cigarette 50 , the entire aroma base material 20 is arranged in the heating region R<b>1 of the insertion hole 51 .

In this way, each of the aroma base materials 20 is distributed in the heating region R1 of the heat-not-burn cigarette 50, so that the heat of the electric heating means 52 is well transmitted to each of the aroma base materials 20, It becomes possible to generate an amount of aerosol suitable for smoking. In addition, by arranging the partition wall 40 with high air permeability between the aromatic base materials 20, the ventilation resistance can be set within an appropriate range.

[Configuration of fragrance base material 20]
The fragrance base material 20 includes a pulverized and dried plant that generates fragrance when heated, and an aerosol former that generates an aerosol when heated. Therefore, the fragrant base material 20 can generate an aerosol containing fragrant components by being heated. The aromatic base material 20 preferably contains at least one of a heat-melting substance that melts when heated, catechin, crosslinked polyvinylpyrrolidone and/or polyvinylpyrrolidone, and perfume. .

In addition to this, the aromatic base material 20 includes, for example, an aromatic agent that can assist the aroma emitted from the pulverized and dried plant material, a molding agent that can improve the moldability of the aromatic base material 20, A binder that contributes to binding and integrating the aerosol former and the pulverized dried product of the plant, a sorbent that allows the aromatic agent to reside in the aromatic base material 20, and improves the storage stability of the aromatic base material 20. It may contain preservatives that allow

(aerosol former)
Aerosol formers are added to generate an aerosol when the scented substrate 20 is heated. Examples of aerosol formers include glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, triethyl citrate, and isopropyl myristate. , methyl stearate, dimethyl dodecanedioate, dimethyl tetradecanedioate and the like can be used, and glycerin and propylene glycol are particularly preferably used.

(Heat melting substance)
The heat-fusible material is added to melt at a relatively low temperature to dissolve and vaporize the fragrance components emanating from the fragrance substrate 20 to facilitate their exhalation together with the aerosol former. In addition, the heat-fusible substance also serves to fix the fragrance source material and/or the fragrance at room temperature.

The heat-melting substance has a melting point in the range of 50-100°C, preferably in the range of 50-80°C, more preferably in the range of 60-67°C. If the melting point of the heat-fusible material is less than 50°C, the heat-fusible material may melt during periods of high temperature such as summer, resulting in stickiness. Further, when the melting point of the heat-melting substance exceeds 100° C., the heat-melting substance is not sufficiently melted at the initial stage of the process of raising the temperature of the aromatic base material, and immediately after the end of the heating process of the heated tobacco, Aerosols tend to lack aroma.

The melting point of the heat-melting substance can be measured, for example, according to the method for measuring the melting point of paraffin wax specified in JIS K2235. That is, using a prescribed melting point tester, put the melted sample in the test tube, read the reading of the melting point thermometer every 15 seconds, and make sure that the temperature drop is within a certain range (the difference is within 0.1 ° C). 5 consecutive times) can be measured as the melting point.

The heat-melting substance is preferably in powder form. The average particle size of the heat-melting substance is preferably 125-355 μm, more preferably 150-300 μm, even more preferably 180-250 μm. The average particle diameter can be measured by, for example, a laser diffraction particle size distribution analyzer. The average particle diameter in the present invention shall mean the median diameter.

If the average particle size of the heat-melting material is too large, the total surface area of the material will be small, thereby reducing the chance of contact with the heat source. As a result, the heat-melting substance is not sufficiently melted, and the concentration of the aromatic component in the aerosol tends to decrease immediately after the end of the heating process.

If the outer diameter of the heat-melting substance is too small, it becomes difficult to form a sea-island structure in which the heat-melting substance is dispersed in the fragrance base material 20 described later. As a result, since each of the heat-melting substances is present in the fragrant base material 20 as aggregated masses, there is a region where the melting speed is reduced due to contact with the heat source, and the concentration of the fragrant component in the aerosol immediately after the end of the heating process tends to decrease. It is preferable that the heat-melting substance is contained in the aromatic base material 20 in an amount of 2 to 20% by mass, preferably 3 to 15% by mass, more preferably 5 to 15% by mass.

The blending amounts of the fragrance source material, the aerosol former, and the heat-melting substance are 55 to 75% by mass, 20 to 40% by mass, and 2 to 15% by mass, respectively, in order to balance the volatilization amount of the smoke component and the fragrance component. %, more preferably 60 to 70 mass %, 25 to 35 mass %, and 3 to 10 mass %.

The heat-melting substance is not particularly limited as long as it is "an organic compound that exhibits a melting point or softening point and becomes a non-Newtonian fluid when heated". The heat-melting substance is preferably an organic compound generally called wax, and typical waxes and waxes that can be used include petroleum-based natural waxes, synthetic waxes, plant-based natural waxes and animal-based natural waxes. . It is also possible to use various tackifiers of which waxes and rosins, which are also used as waxes, belong. These can be used singly or as a mixture containing at least one selected from them.

As the heat-melting substance, natural vegetable waxes and natural animal waxes are preferably used in terms of having a preferable melting point and imparting flavor. Examples of plant-based natural waxes that can be used include wax wax, sumac wax, carnauba wax, sugarcane wax, palm wax, candelilla wax, and the like. Moreover, beeswax, spermaceti, privet wax, wool wax, shellac, etc. can be used as animal-based natural waxes. These have a melting point in the range of 50 to 100° C. as defined in the present invention, and they themselves have a favorable flavor, so that they can enhance the aroma of the aerosol. Among these natural waxes, carnauba wax, beeswax, petrolatum, and paraffin wax are particularly preferred, and beeswax, which has a melting point of 62-65° C. and is rich in aromatic components, is most preferred.

Natural vegetable waxes and natural animal waxes are mainly composed of esters of fatty acids and fatty alcohols. Natural plant waxes and natural animal waxes are mixtures of esters of fatty acids with various carbon numbers and fatty alcohols, and also include free fatty acids, free fatty alcohols, hydrocarbons, and the like. Therefore, natural plant waxes and natural animal waxes are characterized by a wide molecular weight distribution, a wide melting temperature range, and high viscosity when melted.

Since petroleum-based natural waxes are hydrocarbon compounds, they have the advantage of less interaction with aromatic components and aerosol formers, and less adverse effects on flavor. As the petroleum-based natural wax, for example, vaseline, paraffin wax, microcrystalline wax, etc. can be preferably used.

These petroleum natural waxes have different melting temperature ranges based on their molecular structures. Vaseline is a mixture of branched hydrocarbons and alicyclic hydrocarbons, and has a wide melting temperature range of 36 to 60°C.
Paraffin waxes are mainly composed of straight-chain hydrocarbons, have high crystallinity, and mostly exhibit a melting point of 40 to 70° C., with a narrow melting point temperature range.

Microcrystalline wax is a mixture of branched hydrocarbons and saturated cyclic hydrocarbons. It has low crystallinity but high molecular weight. is second only to Vaseline.

All of these petroleum-based natural waxes are hydrocarbon compounds extracted from crude oil. Paraffin waxes and microcrystalline waxes have low melt viscosities and low surface energies when hot melted, and have low interactions with aromatic components and aerosol formers.

Examples of such paraffin waxes include Paraffin Wax-115, 120, 125, 130, 135, 140, 145, 150, and 155, which are standard products manufactured by Nippon Seiro Co., Ltd., any of which are preferably used. . In addition, special paraffin waxes, for example, HNP series products, which are high-purity refined paraffin waxes manufactured by Nippon Seiro Co., Ltd., SP series products for specific applications, and isoparaffins manufactured by special manufacturing methods are the main components. EMW series products are also preferably used. Any of the Hi-Mic series manufactured by Nippon Seiro Co., Ltd. is preferably used as the microcrystalline wax.

Synthetic waxes include, for example, Fischer-Tropsch wax, polyethylene (PE) wax, modified PE wax, polypropylene (PP) wax, modified PP wax, fatty acid amide, fatty acid, fatty alcohol, polyoxyalkylene glycol. , polyoxyethylene alkyl ether, polyoxyethylene alkylamine and the like can be preferably used.

In particular, since Fischer-Tropsch wax is a straight-chain hydrocarbon-based organic compound, it has low melt viscosity and surface energy when melted, and interacts little with aerosol formers and aromatic components. As the Fischer-Tropsch wax, medium melting point product C80 or the like (melting point: about 85 to 88° C.) or the like can be used.

PE wax and modified PE wax, and PP wax and modified PP wax are also hydrocarbon compounds and can be preferably used. Specifically, "High Wax (registered trademark)" manufactured by Mitsui Chemicals Co., Ltd., "Sun Wax" and "Viscol" manufactured by Sanyo Chemical Industries, Ltd., and "CERAFAK (registered trademark) 929, 950, 913, 914 manufactured by BYK , 915” and the like can be preferably used.

In particular, a metallocene-catalyzed polyolefin wax is more preferable because of its narrow molecular weight distribution. For example, "Excelex (registered trademark)" manufactured by Mitsui Chemicals, Inc., which is a metallocene-catalyzed PE wax, has a narrow molecular weight distribution and composition distribution, so it has a melting point of 89 to 128 ° C., but the melt viscosity at the time of heat melting is low. , It is very excellent as such a polyolefin wax.

In addition to the above, fatty acid amides, fatty acids, fatty alcohols, and the like can also be used as heat-melting substances. Monoamides and bisamides are suitable as fatty acid amides. As monoamides, stearic acid monoamide, oleic acid monoamide, and erucic acid monoamide are preferable because they have a melting point of about 72 to 105°C.

The aroma cartridge 100 of the present invention can also contain other physiologically active substances such as catechin, caffeine, and theanine, cooling agents such as menthol, flavoring agents such as coffee extract, perfumes, and the like.

(caffeine)
Caffeine is the most characteristic component of coffee, and is also found in large amounts in foods such as tea, cocoa, and cola. Caffeine is widely known for its stimulating effects, such as drowsiness, and its diuretic effect, which promotes the excretion of urine. Various effects have been clarified, such as "improving athletic ability". By containing caffeine, it is possible to make the user who has inhaled the aerosol feel refreshed, wake up from sleepiness, and provide the user with an antipyretic analgesic effect.

One fragrance cartridge 100 preferably contains 1 to 50 mg of caffeine, more preferably 5 to 30 mg, even more preferably 10 to 20 mg. Caffeine can also be added as a component contained in coffee extract as a flavoring agent, which will be described later.

(Theanine)
Theanine can be contained in the aromatic base material 20 using, for example, an extract obtained by extracting tea leaves with hot water, green tea leaf powder, green tea leaf extract, green tea leaf perfume, or the like.

Fragrance to be felt; and the like are preferable.

(sorbent)
In the present invention, it is preferable to use a sorbent in order to prevent volatilization of the cooling agent, perfume, etc. before the temperature of the fragrance base material 20 reaches the optimum temperature at which the aerosol former and the fragrance source material volatilize. . As described above, the sorbent can cause the heated fragrance-generating material 20 to retain fragrances such as cooling agents and fragrances.

As one preferred embodiment of the sorbent, it is possible to use a sorbent that retains the compound in the fragrance-generating substrate 20 by adsorbing it. For example, when the compound is menthol, menthol has a phenolic hydroxyl group. Therefore, as the sorbent, hydrophilic crosslinked polymers capable of adsorbing phenolic hydroxyl groups, such as crosslinked polyvinylpyrrolidone (PVPP) and polyvinylpyrrolidone (PVP), can be used.

Also, for example, when the compound is nicotine, nicotine has a five-membered heterocyclic compound containing nitrogen. Therefore, crosslinked PVP, which is believed to form an interaction with a nitrogen-containing five-membered heterocyclic compound, can be used as the sorbent.

When crosslinked PVP and/or PVP is used as the sorbent, the sorbent preferably contains 4 to 25% by mass with respect to the total amount of 100% by mass of the fragrance source material, the aerosol former and the heat-melting substance. It is more preferably contained in an amount of up to 20% by mass.

As the sorbent, a sorbent that retains the compound in the fragrance-generating substrate 20 by encapsulating the compound can be used, and cyclodextrin can be used as such a sorbent.

Cyclodextrins are known to form inclusion compounds with chemical substances having hydroxyl groups and carboxyl groups of various sizes, and any of α, β, and γ-cyclodextrins can be used. In particular, β-cyclodextrin forms an inclusion compound with menthol and is most suitable as a sorbent for menthol.

When cyclodextrin is used as the sorbent, the sorbent preferably contains 0.1 to 1.2% by mass with respect to 100% by mass of the total amount of the fragrance source material, the aerosol former and the heat-melting substance. .2 to 1.0% by mass is more preferable.

The sorbent also serves to adsorb and retain physiologically active substances such as catechin, caffeine, and theanine.
It is more preferable that the sorbent contains both PVPP and cyclodextrin.

(molding agent)
Molding agents are used to reinforce the physical strength of the fragrance base material 20 . Examples of molding agents that can be used include cellulose fibers and microcrystalline cellulose.

Cellulose fibers such as sugarcane, bamboo, wheat, rice, esparto, jute, hemp, and wood are preferably used as cellulose fibers. These cellulose fibers preferably have a fiber diameter of 5 to 25 μm and a fiber length of 0.25 to 6 mm. By using cellulose fibers having a fiber diameter and fiber length within such ranges, it is possible to enhance the effect of binding the constituent components of the fragrance base material 20 .

Further, the microcrystalline cellulose preferably has an average particle size of 70 to 120 μm. If the average particle size of the microcrystalline cellulose is less than 70 μm, it tends to be difficult to suppress shrinkage of the aromatic base material 20 and prevent adhesion between the aromatic base material 20 and the molding machine. When the average particle diameter of microcrystalline cellulose exceeds 120 μm, the fragrance base material 20 tends to break easily. The average particle size of microcrystalline cellulose can be measured with a laser diffraction particle size distribution analyzer. The average particle diameter in the present invention shall mean the median diameter.

Further, the mass average molecular weight (Mw) of microcrystalline cellulose is preferably 20,000 to 60,000. If the mass average molecular weight (Mw) of the microcrystalline cellulose is less than 20,000, the effect of suppressing the shrinkage of the aromatic base material 20 tends to be poor. When the mass average molecular weight (Mw) of microcrystalline cellulose exceeds 60,000, the fragrance base material 20 tends to break easily.

The molding agent is preferably contained in an amount of 2 to 25% by mass, preferably 3 to 20% by mass, based on 100% by mass of the total amount of the fragrance source material, the aerosol foamer and the heat-melting substance. By containing the forming agent in the fragrance base material 20 in such a manner, it is possible to fulfill the above function and prevent the forming agent from being a detrimental factor in the generation of volatile substances in the fragrance source material and the aerosol former. .

(binder)
Binders are used to bind raw materials such as fragrance sources, aerosol formers, and heat-fusible substances that constitute the fragrance base material. Examples of binders that can be used include polysaccharide-based polymers, cellulose-based polymers, and calcium carbonate.

Examples of polysaccharide polymers that can be used include konjac mannan (glucomannan), guar gum, pectin, carrageenan, tamarin seed gum, gum arabic, soybean polysaccharides, locust bean gum, karaya gum, xanthan gum, and agar. Polysaccharide-based polymers are preferably glucomannan, guar gum, pectin, carrageenan, tamarin seed gum, locust bean gum, karaya gum, and xanthan gum from the viewpoint of strength and molding processability. Neutral polysaccharides glucomannan, Guar gum, tamarin seed gum and locust bean gum are more preferred.

Examples of cellulosic polymers include carboxymethyl cellulose (CMC), carboxyethyl cellulose, hydroxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, CMC sodium salt, CMC potassium salt, CMC calcium salt, carboxyethyl cellulose sodium salt, carboxy A potassium salt of ethyl cellulose, a calcium salt of carboxyethyl cellulose, or the like can be used. The cellulosic polymer is preferably sodium salt of CMC, potassium salt of CMC, sodium salt of carboxyethylcellulose, or potassium salt of carboxyethylcellulose, from the viewpoint of the strength and moldability of the aromatic base material 20 .

As a binder, it is preferable to use a polysaccharide-based polymer and a cellulose-based polymer in combination. In this case, it is preferable to use glucomannan, guar gum, tamarin seed gum, and locust bean gum as the polysaccharide-based polymer. As the cellulosic polymer, it is preferable to use sodium salt of CMC, potassium salt of CMC, sodium salt of carboxyethyl cellulose, and potassium salt of carboxyethyl cellulose. Thus, by using a polysaccharide-based polymer and a cellulose-based polymer in combination, the strength and moldability of the aromatic base material 20 can be improved.

The binder is preferably contained in an amount of 5 to 30% by mass, more preferably 8 to 28% by mass, based on 100% by mass of the total amount of the fragrance source material, the aerosol former, and the heat-melting substance. . Since the binder is contained in the aromatic base material 20 in such a content, the strength and molding processability of the aromatic base material 20 can be improved, and the generation of volatile substances from the fragrance source material and the aerosol former, etc. can be avoided.

Moreover, it is preferable that both the binder and the molding agent are contained in the fragrance base material 20 of the present invention. In this case, the compounding ratio of the binder and the molding agent is preferably 1:1 to 1:25 in terms of the binding effect.

(Preservative)
A preservative may be used for long term storage of the heated fragrance generating cartridge. As preservatives, for example, potassium sorbate and/or sodium benzoate can be used. The preservative is preferably contained in an amount of 0.005 to 0.04% by mass with respect to 100% by mass of the total amount of the fragrance source material, the aerosol former, and the heat-melting substance.

Next, a method for manufacturing the fragrance base material 20 will be described. FIG. 5 shows one embodiment of the manufacturing process of the fragrance base material 20 . As shown in FIG. 5, a raw material (A) containing a fragrance material that is a pulverized and dried product of a plant that constitutes a fragrance, a flavor material that is a pulverized and dried product of a plant that constitutes a flavor, and a pulverized and dried plant that constitutes an aroma. A mixing step is performed to mix the raw material (B) containing aroma materials and the like. The mixing step is performed below the melting point of the hot melt material. A mixing process can be performed using a well-known mixer, for example.

The raw material (A) includes a raw material (A1) containing a fragrance material that is a pulverized and dried product of a plant that constitutes a fragrance, a flavor material that is a pulverized and dried product of a plant that constitutes a flavor, and a raw material containing a heat-melting substance ( A2), a raw material (A3) containing an aqueous alcohol solution of microcrystalline cellulose, an aqueous alcohol solution of a binder, and an aqueous alcohol solution of a sorbent, and a raw material (A4) containing an aerosol former, a fragrance agent and a molding agent are mixed, Obtained by aging.

The mixing of the raw materials (A1) to (A4) is performed below the melting point of the heat-melting substance. Moreover, this mixing process can be performed using a well-known mixer, for example.

The raw material (A1) is obtained by pulverizing the fragrance material after sterilizing it.

The raw material (A2) is obtained by pulverizing a mixture of the flavor material and the heat-melting substance after sterilization. Specifically, as shown in FIG. 6, the flavor material is sterilized and then pulverized into a predetermined size. Also, the powdery heat-melting substance is heated and mixed at a temperature equal to or higher than the melting point of the heat-melting substance, cooled, and then pulverized into a predetermined size. The pulverized product and the powdered flavor material are mixed by compression and shearing, cooled and then pulverized to prepare the raw material (A2).

The raw material (A3) is obtained by mixing an aqueous alcohol solution of microcrystalline cellulose, an aqueous alcohol solution of a binder, and an aqueous alcohol solution of a sorbent (crosslinked polyvinylpyrrolidone and/or polyvinylpyrrolidone). The aqueous alcohol solution is a mixture of pure water and ethanol.

Raw material (A4) is obtained by mixing an aerosol former, fragrance and shaping agent.

Aging is preferably carried out, for example, at a temperature of 15 to 30° C. for 3 to 14 days. From the viewpoint of retaining aromatic components, aging is more preferably carried out at a temperature of 20±2° C. for 4 to 7 days. If the temperature exceeds 30° C. or the aging period exceeds 14 days, there is a tendency for the possibility of mold and spoilage to increase.

The raw material (B) is obtained by mixing the raw material (B1) containing aroma materials, which are pulverized and dried plants constituting aroma, and the raw material (B2) containing preservatives. The raw materials (B1) and (B2) can be mixed using, for example, a known mixer.

The raw material (B1) is obtained by pulverizing an aroma material after sterilization.
Raw material (B2) is obtained by dissolving a preservative in pure water.

By performing the mixing step of mixing the raw material (A) and the raw material (B) in this way, it is possible to form a sea-island structure in which the powder of the heat-melting substance mixed with the fragrance source material is dispersed in the fragrance base material 20. can.

Next, the mixture obtained in the mixing step is compressed and sheared to form a sheet. Compression/shearing can be performed using, for example, three rolls. By compressing and shearing with three rolls, it is possible to form a sheet while entraining air and evaporating water.

The sheet thus obtained has a porous structure containing air therein. As a result, it becomes possible to obtain the aromatic base material 20 with a low density. Also, since the rolls of the three rolls have extremely flat surfaces, the surface of the sheet is formed flat.

That is, the aromatic base material 20 has a porous structure containing air in the compression/shearing process, so that it has a low density and a flat surface without unevenness.

The mixture formed into a sheet by compressing and shearing is cut into a predetermined shape and size, and a cutting process is performed. A sheet-shaped mixture is processed into strip shape, for example.

In this way, the mixing process, compression/shearing process, and cutting process are performed below the melting point of the heat-melting substance, thereby preventing the melting of the heat-melting substance from spreading throughout the aromatic base material 20, and preventing the aromatic base material 20 from spreading. It becomes possible to maintain the sea-island structure of the heat-melting substance.

When a sea-island structure is formed in which the powder of the heat-melting substance mixed with the fragrance source material is dispersed in the fragrance base material 20, the heat-melting substance is dispersed and arranged in the form of islands in the fragrance base material 20. - 特許庁

When the heat-melting substance is dispersed in the form of islands on the fragrance base material 20, it flows more easily when melted than when it is impregnated with the fragrance source material, and is generated from the fragrance source material. Fragrance components are likely to be contained. In addition, the flowing heat-melting substance contacts with the aerosol former, and the aromatic component becomes an aerosol together with the aerosol former and can be easily volatilized.

As a result, it is possible to efficiently volatilize the aromatic component of the fragrance source material. Therefore, the user can fully enjoy the aroma when inhaling the aerosol emitted from the aroma cartridge 100 immediately after the heat-not-burn cigarette is heated.

Incidentally, the heat-melting substance may be added to the raw material (B). FIG. 7 shows another embodiment of the manufacturing process of the fragrance base material 20. As shown in FIG. As shown in FIG. 7, when the heat-melting substance is added to the raw material (B), it is preferably added to the raw material (B1), for example.

As described above, according to the fragrance cartridge 100 of the present invention, it is possible to reduce the ventilation resistance in the axial direction of the cover 10 . Therefore, it is possible to improve the ease of inhaling the aerosol generated from the fragrance base material 20 . In addition, since the aerosol and air can be mixed in an appropriate distribution, it is possible to improve the flavor.

[Embodiment 2]
The aroma cartridge 100 of Embodiment 2 differs from the aroma cartridge 100 of Embodiment 1 in that a regulating member that regulates axial movement of the cover 10 of the aroma base material 20 is used. The same components as those of the fragrance cartridge 100 of Embodiment 1 are denoted by the same reference numerals, and descriptions thereof are omitted.

As shown in FIG. 8 , the regulating member 60 is provided in contact with the fragrance base material 20 arranged on the most proximal side of the cover 10 among the two fragrance base materials 20 . In this embodiment, the regulation member 60 is formed in a substantially cylindrical shape and has one or a plurality of air passages 61 passing therethrough in the axial direction. Therefore, the restricting member has air permeability in the axial direction of the cover 10 .

In this embodiment, the air passage 61 is defined by four concave grooves formed along the axial direction at regular intervals in the outer peripheral surface of the regulating member 60 and the inner peripheral surface of the cover 10 . there is

The air passages 61 are, for example, arranged side by side in the circumferential direction so as to surround a central air passage formed along the axis of the regulating member 60, and to penetrate the central air passage in the axial direction. It may be composed of a plurality of air passages 41 formed in the same.

Further, the regulating member 60 may be configured by a honeycomb structure or the like having partition walls with hexagonal end faces and a plurality of air passages penetrating in the axial direction. Further, the regulating member 60 may be composed of, for example, a porous body in which open cells are formed.

When the electric heating means of the heat-not-burn cigarette is inserted into one or both end faces of the cover 10 in the axial direction, preferably the end face arranged on the side of the aroma base material 20, the regulating member 60 controls the aroma base material. It is preferable to have a shape capable of restricting the movement of the cover 10 in the axial direction. Here, the shape that can restrict the movement of the fragrance base material 20 in the axial direction of the cover 10 may be, for example, a shape that can restrict the movement of the material of the fragrance base material 20 to the extent that there is no practical problem. .

By forming the regulating member 60 in this manner, the regulating member 60 regulates the movement of the fragrance base material 20 to the other end side. In other words, the regulation member 60 can support the fragrance base material 20 .

In addition, the regulating member 60 can cool the high-temperature aerosol when the aerosol containing the aromatic component generated from the fragrance base material 20 passes through. Therefore, the regulating member 60 is made of a member having heat resistance corresponding to the combustion temperature or heating temperature of the fragrance cartridge 100 . For example, if the aroma cartridge 100 is a heated tobacco cartridge, the regulating member 60 may be made of a member having heat resistance of about 180 to 400.degree.

Examples of such members include paper, resin, rubber, wood, metal, ceramics, and the like, but resins that can be molded into various shapes are more preferable.

The resin may be either a thermoplastic resin or a thermosetting resin, such as polyolefin resin, polyester resin, polystyrene resin, nylon resin, acrylic resin, silicon resin, fluorine resin, polyurethane resins, ethylene-vinyl acetate (EVA) resins, phenolic resins, amino resins, ABS resins, and biodegradable plastics. Among these resins, biodegradable plastics are preferable from the viewpoint of protecting the natural environment because the fragrance cartridge 100 becomes a waste product after being used.

Examples of biodegradable plastics include poly(3-hydroxybutyrate) (PHB), poly(ε-caprolactone) (PCL), poly(butylene succinate) (PBS), and polylactic acid (PLA). mentioned.

According to such an aspect, it becomes possible to hold the aromatic base material 20 arranged on the proximal end side of the cover 10 at a predetermined position in the cover 10 by the regulating member 60 . As a result, when the aroma cartridge 100 is attached to the heating type cigarette 50 , the aroma base material 20 can be held at a position suitable for heating by the electric heating means 52 .

[Embodiment 3]
The fragrance cartridge 100 of Embodiment 3 differs from the fragrance cartridges 100 of Embodiments 1 and 2 in that a cover member that prevents the fragrance base material 20 from flowing out from the cover 10 is used. The same components as those of the fragrance cartridges 100 of Embodiments 1 and 2 are denoted by the same reference numerals, and descriptions thereof are omitted.

As shown in FIG. 9, the fragrance substrate 20' can be an aggregate of particulate components in this embodiment. In this embodiment, the fragrance base material 20' is formed into a generally cylindrical shape with granular components.

A lid member 70 is provided on the tip side of the cover 10 to close the opening of the cover 10 on the tip side. The lid member 70 has air permeability in the axial direction of the cover. The breathability should be at least the breathability necessary for smoking, and preferably has the same degree of breathability as the filter 30, for example.

The lid member 70 can be formed of, for example, a paper member such as Japanese paper, a porous member, a honeycomb structure, a mesh structure, or the like.

According to this aspect, since the lid member 70 closes the opening of the cover 10 on the tip side, it is possible to prevent the fragrance base material 20 ′ from flowing out of the opening of the cover 10 .

[Embodiment 4]
The fragrance cartridge 100 of Embodiment 4 differs from the fragrance cartridges 100 of Embodiments 1 to 3 in the form of the partition wall. The same components as those of the fragrance cartridge 100 of Embodiments 1 to 3 are denoted by the same reference numerals, and the description thereof is omitted.

As shown in FIG. 10, the partition wall 42 is formed like cotton. The partition wall 42 is made of, for example, fibers (either natural fibers or synthetic fibers) having heat resistance corresponding to the temperature range (for example, 180 to 400° C.) heated by the electric heating means of the heated cigarette. good) are entangled with each other to form clumps. The partition wall 42 has at least the same ventilation resistance as the filter 30 in the axial direction of the cover 10 .

The form of the partition is not limited to such a form, and for example, as shown in FIG. 11, two disk-shaped partitions 43 may be used. Each of the partition walls 43 has a through hole 44 formed in its center in the thickness direction. Each of the partitions 43 can be fixed to the wrapping paper 11 with an adhesive or the like, for example. Therefore, the partition wall 43 has at least the same ventilation resistance as the filter 30 in the axial direction of the cover 10 .
