Description

Technical Field

[0001] The present invention relates to a heated aroma generating substrate provided in a heated smoking article suitable for a heated smoking device, a heated aroma cartridge including the heated aroma generating substrate, and a method for manufacturing the heated aroma generating substrate.

[0002] In particular, the heated aroma generating substrate of the present invention is manufactured through a molding process in which at least an aroma source material, an aerosol former, and a binder are mixed and then a compressive shear force is applied. The heated aroma generating substrate is characterized in that the aroma source material, the aerosol former, and the binder are uniformly dispersed and bound. As a result, when the heated aroma cartridge including the heated aroma source composed of the heated aroma generating substrate of the present invention is detached from the heated smoking device, problems such as deformation, detachment, and dropping of the heated aroma generating substrate do not occur. In smoking, the aroma volatilized from the heated aroma source material can be fully enjoyed. In the manufacture of the heated aroma generating substrate, the aroma source material, the aerosol former, and the binder are uniformly dispersed and bound, and have the toughness and strength required for the molding process, so stable production is possible.

[0003] Further, the heated aroma generating substrate of the present invention is characterized in that when a cooling agent such as menthol or xylitol is added as an aromatic agent, the dissipation of the cooling agent over time is suppressed. Even after a heated aroma cartridge including the heated aroma source including the same is stored for a long time, when it is attached to a heated smoking device and smoked, the aroma of the heated aroma generating substrate can be fully enjoyed.

[0004] Furthermore, the heated aromatic generating substrate of the present invention is characterized by having little dimensional change due to drying. Even after mounting a heated aromatic cartridge provided with a heated aromatic generating source composed of the substrate on a heat-not-burn smoking device and smoking, there is no dropping or falling of the heated aromatic generating substrate from the heated aromatic cartridge. Even after long-term storage, there is no dropping or falling of the heated aromatic generating substrate from the heated aromatic cartridge. It has excellent handleability and has the effect of preventing contamination of the heat source of the heat-not-burn smoking device.

[0005] Incidentally, conventionally, the above-mentioned "heated aromatic generating substrate" was often referred to as an "aerosol forming substrate". However, by heating, together with an aerosol former that forms an aerosol, the fragrance components of the fragrance source material and the fragrance agent are also volatilized, and the smoker enjoys the smoke of the aerosol and the fragrance of the fragrance source material and the fragrance agent by smoking. Therefore, in the present invention, it is referred to as a "heated aromatic generating substrate". Based on this, an "aerosol forming body" filled with an aerosol forming substrate and an "e-cigarette cartridge" provided with the aerosol forming body are respectively referred to as a "heated aromatic generating source" and a "heated aromatic cartridge". However, the term "heated aromatic cartridge" is not limited and may be referred to as a "smoking cartridge" or an "e-cigarette compatible cartridge".

[0006] Also, the material that serves as the fragrance source is not limited, and tobacco plants of the genus Nicotiana, plants of the same genus, and non-tobacco plants that do not contain tobacco components can be used. "Fragrance" means "pleasant smell", and it is possible to feel, during smoking, the smell (fragrance) wafting from the material itself, the smell (aroma) wafting in the air when heated, the smell (flavor) wafting in the mouth when inhaled, etc. "Smoking" generally means inhaling cigarettes or cigars, etc., but here it simply means "enjoying the smoke", "tasting the fragrance", "appreciating the smoke and fragrance". Therefore, the "smoke" here is not generated by combustion, but is, for example, something "that looks like smoke" or "smoky", such as droplets dispersed in the air like an aerosol.

Background Art

[0007] In recent years, smoking bans have been widely spreading in spaces where people gather, such as workplaces and restaurants. In response, tobacco manufacturers have developed a method of smoking a heat-generating aromatic cartridge that generates an aerosol by heat transmitted from an electronically controlled blade-type heat source when installed in the chamber of a heat-not-burn smoking device (Patent Document 1). This heat-generating aromatic cartridge is provided with a heat-generating aromatic source formed using a heat-generating aromatic generating base material containing an aerosol former, an aromatic source material containing a tobacco plant of the Solanaceae tobacco genus, and a binder, etc. When the heat-generating aromatic generating base material is heated, volatiles are generated. The volatiles of the aerosol former are cooled into smoke, and the volatiles of the aromatic source material become aromas, allowing one to enjoy smoking similar to combustible tobacco. According to this heat-not-burn smoking, since the inhalation of harmful components generated by the thermal decomposition and combustion of conventional tobacco is reduced, while the number of combustible tobacco smokers has been rapidly decreasing, the number of heat-not-burn tobacco smokers has been increasing rapidly. For this reason, active technological development is being carried out to make heat-not-burn smoking more enjoyable (for example, Patent Documents 1 to 12).

[0008] Such a mechanism for heated smoking varies depending on the form of the heated smoking device, the heated aroma cartridge, etc. A typical example is shown below. A heated aroma generation source filled with a heated aroma generation base material at one end and a heated aroma cartridge equipped with a mouthpiece at the other end is mounted so that the heated aroma generation source comes into contact with the heat source of the heated smoking device and is heated. Then, volatiles such as an aerosol former and an aroma source material are released from the heated aroma generation source. This volatile is inhaled together with air to the mouthpiece side at the other end by the smoker's suction. In this volatile transport process, the volatile of the aerosol former cools and condenses to form an aerosol like smoke, and other volatiles give an aroma to the smoker's mouth and nose, and as a result, smoking can be enjoyed. Therefore, in the case of heated smoking, it is possible to smoke at a temperature of about 200 to 350 °C at which the aerosol former such as glycerin or propylene glycol contained in the heated aroma generation base material can be volatilized, that is, at a temperature at which the thermal decomposition of tobacco leaves starts. Thus, not only can the generation of harmful substances due to combustion be prevented, but also the generation of harmful substances due to thermal decomposition can be reduced.

[0009] As can be seen from this mechanism, in a heated smoking device, the heat source that has a great influence on the generation of smoke and aroma and its control method play extremely important roles. As a result of continuous development over the years, the blade type heat source by a heater has been widely used until now (for example, Patent Documents 1 to 5). On the other hand, recently, an omnidirectional heat source by electromagnetic induction heating has been put into practical use. It is considered that the aim is to increase the generation of volatiles and provide a deep flavor because of its high heating speed and large contact area with the heated aroma generation base material (Non-Patent Document 1).

[0010] On the other hand, regarding the technological development of a heat-generating aromatic generating substrate that is a source of generating smoke and aroma, various efforts have also been made (for example, Patent Documents 6 to 12). It has an aerosol former with a boiling point of 180 to 300 °C, such as glycerin and propylene glycol, which are the sources of smoke, as an essential component, and it is necessary to form a homogeneous viscoelastic body by mixing with a tobacco plant, a non-tobacco plant, which are aromatic source materials serving as the source of aroma, and fragrances, etc. Therefore, linear, side-chain, and branched polysaccharide-based polymers such as cellulose, guar gum, and gum arabic are used as binders. In addition, it is necessary to add a wetting agent or the like for uniformly dispersing these.

[0011] However, conventionally, for the heat-generating aromatic generating substrate, a method of casting and molding by a papermaking process in which an aqueous slurry in which an aerosol former, an aromatic source material, a binder, a wetting agent, etc. are dispersed in water is manufactured and then subjected to a compression and heat drying process after the papermaking process, or a method of extrusion molding a viscoelastic body obtained by adding an appropriate amount of a lower alcohol or water to a mixture of an aerosol former, an aromatic source material, a binder, a wetting agent, etc. has been adopted (Patent Documents 6 and 7). However, with these methods, it is not possible to manufacture a viscoelastic body in which the components constituting the heat-generating aromatic generating substrate are homogenized, and since the mechanical strength of the molded product is insufficient, there are often problems of breakage at the stage of processing from the heat-generating aromatic generating substrate to the heat-generating aromatic generating source. In addition, since the heat-generating aromatic generating substrate that is not homogenized has an insufficient packing state of the aromatic source and the binder, it shrinks severely when heated and dried, and there are problems of breakage during the heat drying at the stage of processing into the heat-generating aromatic generating source, or the heat-generating aromatic generating substrate falling off or dropping after smoking.

[0012] Regarding the falling off or dropping, cracking, or breakage of the heat-generating aromatic generating substrate after smoking, the effectiveness of an inorganic binder has been disclosed (Patent Document 8). This solution is based on the fact that the inorganic binder does not improve the inhomogeneity but suppresses the combustion of the heat-generating aromatic generating material by improving the heat resistance to the heat source. Moreover, since the relative proportions of the aromatic source material and the aerosol former in the heat-generating aromatic generating substrate decrease, there is a problem of a decrease in the amount of generated aroma and smoke.

[0013] In addition, inhomogeneities resulting from the chemical properties of the components constituting the heat-generating aromatic generating substrate also lead to a decrease in the amounts of aroma and smoke generated. In particular, since the chemical affinity between the aroma source material and the aerosol former is low, the aroma source material cannot be dissolved in the aerosol former and has to be dispersed. As a result, aerosol formers of various volumes and lumps of aroma source materials of various sizes will exist irregularly. Therefore, even in the case of such a heat-generating aromatic generating substrate in a heterogeneous state, even when heated by a heat source, uniform heat transfer to the aroma source material and the aerosol former cannot be achieved. As a result, the aromatic components of the aroma source material are not sufficiently volatilized, resulting in an insufficient taste in smoking. At the same time, the aerosol former is also not sufficiently volatilized and cannot generate enough smoke to please the smoker's eyes. To address such problems, a solution has been proposed in which wax is added to enhance the fluidity of the volatile components of the aroma source material and the aerosol former and to promote the dissipation of volatiles from the heat-generating aromatic generating substrate (Patent Documents 9 and 10). However, since wax is hydrophobic, it is particularly difficult to manufacture a homogenized heat-generating aromatic generating substrate by a manufacturing method such as the casting method, and a great improvement effect cannot be expected. In addition, due to the wax, there is also a problem of mechanical strength in that the heat-generating aromatic generating substrate becomes brittle.

[0014] Furthermore, in heated tobacco, similar to combustible tobacco, in order to obtain a refreshing feeling when smoking, a cooling agent such as menthol or xylitol may be added as a fragrance. Also, a flavoring agent may be added to add flavors such as fruits and nuts. Even in such cases, in the heating and drying process for manufacturing the heated aroma-generating substrate by the casting method described above, there is a problem that the cooling agent and the flavoring agent dissipate. Along with this, the hydrophilic-hydrophobic balance of the components constituting the heated aroma-generating substrate, including the cooling agent and the flavoring agent, and a large amount of components that are insoluble in the aerosol former are contained and not homogenized, so there is a problem that the cooling agent and the flavoring agent dissipate over time. In response to these problems, the inclusion of the cooling agent and the flavoring agent by various cyclodextrins and the encapsulation of the cooling agent and the flavoring agent by wax have been disclosed as means for solving these problems (Patent Documents 11 and 12). In order to form the former inclusion compound, it is necessary to find an appropriate combination of a cooling agent and a flavoring agent and cyclodextrin, and further, after selecting an appropriate solvent and homogenizing the cooling agent, the flavoring agent, and cyclodextrin with a homogenizer, spray drying, freeze drying, or vacuum drying must be performed. Therefore, the applicable cooling agents and flavoring agents are limited, and a great deal of labor is required for production.

[0015] As described above, based on the manufacturing methods of cast molding and extrusion molding and the chemical properties of the components, there is a problem of inhomogenization in the heated aroma-generating substrate. This problem may be solved by adopting a compression-shearing processing method as the manufacturing method. For example, a three-roll mill that can uniformly knead and disperse a high-viscosity paste by compression caused by being pushed between narrow rolls and shearing caused by a roll speed difference, and can form a sheet is conceivable. However, in this case, due to the insufficient strength and high adhesiveness of the sheet that becomes the heated aroma-generating substrate, aggregation breakdown and adhesion to the metal roll occur, resulting in a problem that it is difficult to perform forming processing on the sheet.

[0016] Thus, in order to smoke a heated tobacco product, that is, to enjoy smoking by attaching a heat-generating aroma cartridge to a heat-not-burn smoking device, it is necessary to further solve various problems caused by the composition of the heat-generating aroma generating base material that constitutes the heat-generating aroma source of the heat-generating aroma cartridge along with the improvement of the heat-not-burn smoking device.

Summary of the Invention

Problems to be Solved by the Invention

[0019] The present invention relates to a heated aroma generating base material provided in a heated aroma cartridge suitable for a heated smoking device, which contains at least an aroma source material, an aerosol former, and a binder, and after mixing these, is manufactured through a molding process to which a compressive shear force is applied, and is characterized in that the aroma source material, the aerosol former, and the binder are uniformly dispersed and bound. The purpose is to provide such a heated aroma generating base material.

[0020] As a result, when detaching a heated aroma cartridge equipped with a heated aroma source composed of the heated aroma generating base material of the present invention from a heated smoking device, problems such as deformation of the heated aroma generating source, detachment and dropping of the heated aroma generating base material are solved, and toughness and strength necessary for this molding process are imparted, and a heated aroma generating base material that can fully enjoy the aroma volatilized from the heated aroma source material can be provided.

[0021] In addition, when a cooling agent such as menthol or xylitol is added as a fragrance to the heated fragrance-generating base material of the present invention, the dissipation of the fragrance and the cooling agent over time is suppressed. Even after storing a heated fragrance cartridge equipped with a heated fragrance source containing the same for a long period of time, when it is attached to a heat-not-burn smoking device and smoked, it is possible to fully enjoy the fragrance of the heated fragrance-generating base material. The purpose is to provide a heated fragrance-generating base material.

[0022] Furthermore, the heated fragrance-generating base material of the present invention has little dimensional change due to drying. Even after a heated fragrance cartridge equipped with a heated fragrance source containing the same is attached to a heat-not-burn smoking device and smoked, there is no dropping or falling of the heated fragrance-generating base material from the heated fragrance cartridge. Even after long-term storage, there is no dropping or falling of the heated fragrance-generating base material from the heated fragrance cartridge, it has excellent handleability, and the purpose is to provide a heated fragrance-generating base material capable of preventing contamination of the heat source of the heat-not-burn smoking device.

[0023] Thus, the main problems to be solved by the present invention are the homogeneous mixing and dispersion of materials with different properties such as a fragrance source material, an aerosol former, a binder, and a fragrance in a conventional heated fragrance-generating base material, as well as preventing the easy dissipation of the fragrance over time and preventing shrinkage of the shape over time and due to heat.

Means for Solving the Problems

[0024] As a result of various studies on various materials in addition to the fragrance source material, aerosol former, binder, and fragrance that constitute the heated fragrance-generating base material, the inventor has found that by selecting two types of binders and their appropriate blending methods, and adding crosslinked polyvinylpyrrolidone (PVP) and microcrystalline cellulose, the above problems can be solved, leading to the completion of the present invention.

[0025] That is, the present invention is a heat-generating aromatic substrate containing at least an aromatic source material, an aerosol former, and a binder. The binder contains a first binder and a second binder. The first binder is at least one cellulose-based polysaccharide selected from the group consisting of methylcellulose, ethylcellulose, carboxymethylcellulose, carboxyethylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, and hydroxypropylcellulose, and their sodium salts, potassium salts, and calcium salts. The second binder is a polysaccharide other than at least one cellulose-based polysaccharide selected from the group consisting of glucomannan, guar gum, pectin, carrageenan, locust bean gum, and agar. The heat-generating aromatic substrate is characterized by this.

[0026] By using such a first binder and a second binder in combination, the aromatic source material and the aerosol former constituting the heat-generating aromatic substrate are homogeneously mixed and dispersed, and the binding force between the two is enhanced, resulting in a heat-generating aromatic substrate having the toughness and strength required for molding. As a result, even immediately after manufacturing a heat-generating aromatic cartridge equipped with this heat-generating aromatic substrate, or after storing it for a long time, it can be detached from the heat-smoking device without causing the heat-generating aromatic substrate to fall off, drop, or deform. Also, the aroma from the aromatic source material and the smoke generation by the aerosol former during smoking occur sufficiently. Furthermore, since the aromatic source material and the aerosol former are homogeneously mixed and dispersed through the binder, even in the case of molding using a compression shear force, for example, when using three rolls, it is possible to perform molding into a sheet-like heat-generating aromatic substrate without causing aggregate breakdown. And in order to be a heat-generating aromatic substrate having such an effect, its breaking strength in the tensile strength test is 0.167 N / mm 2 or more was confirmed.

[0027] In order to stably exhibit the above effects by using the first binder and the second binder in combination, a first mixing step of mixing the fragrance source material, the aerosol former, and the first binder and a second mixing step of mixing the second binder into the mixture produced in the first mixing step, or a mixing and molding step of molding into a heated fragrance generating substrate while mixing the second binder into the mixture produced in the first mixing step of mixing the fragrance source material, the aerosol former, and the first binder. It is preferable to adopt a manufacturing process for mixing the binders step by step. Although the reason for this is not clear, it is considered that the first binder, which is a cellulose-based polysaccharide, promotes the uniform mixing and dispersion of the fragrance source material and the aerosol former to form a stable sol state, and then the second binder, which is a polysaccharide other than the cellulose-based polysaccharide, forms a gel state that enhances these bindings.

[0028] To support this speculation, when the first binder and the second binder are mixed by swapping them, a phenomenon was observed in which partially gelled lumps were generated in the mixture of the fragrance source material, the aerosol former, and the binder, and a uniform dispersion state could not be generated.

[0029] Furthermore, it is more preferable to add a curing step of curing the mixture produced in the first mixing step immediately after the first mixing step. When the temperature of the curing step is 15°C or higher and 30°C or lower, and the time of the curing step is 72 hours or longer and 336 hours or shorter, in particular, the combined effect of the first binder and the second binder is maximally exerted. This curing step is presumed to have the effect of increasing and stabilizing the degree of dispersion of the aroma source material in the sol state formed by promoting the uniform mixing and dispersion of the aroma source material and the aerosol former by the first binder of the cellulose-based polysaccharide. This is because an increase in the volume of the mixture is observed in the curing step. When the temperature is less than 15°C, the volume increase is also slight, and the effect of the curing step on the quality of the heat-generating aroma-generating base material is not recognized. When the temperature exceeds 30°C, although the cause is unknown, gelation of the mixture is observed. When the time is less than 72 hours, the volume increase is also slight, and the effect of the curing step on the quality of the heat-generating aroma-generating base material is not recognized. When the time exceeds 336 hours, this volume increase stops, the effect of the curing step on the quality of the heat-generating aroma-generating base material saturates, and further long-term curing may cause gelation.

[0030] When such a curing step is performed, it is not necessary to add the first binder and the second binder step by step. A manufacturing process can be adopted in which a third mixing step of mixing the aroma source material, the aerosol former, the first binder, and the second binder is provided, and a curing step of curing the mixture produced in the third mixing step is provided. In this curing step, it is considered that the effect of increasing the degree of dispersion of the aroma source material by the first binder and the effect of increasing the binding by the second binder occur in parallel.

[0031] The binder is preferably a combination of the above-mentioned cellulose-based polysaccharide and other polysaccharides, and furthermore, it is preferable to further add cellulose fibers extracted from plants containing a large amount of cellulose fibers. In particular, linen, jute, moringa, kenaf, hemp, manila hemp, sisal hemp, etc. with a fiber diameter of 10 to 50 μm, as well as cellulose fibers of gramineous plants such as rice, oats, barley, wheat, rye, adzuki bean, triticale, sugarcane, esparto, and bamboo can uniformly mix, disperse and bind the materials constituting the heated aromatic generating base material, and can impart the toughness and strength required for molding processing, and have a high effect of preventing deformation, falling off, and dropping. Also, in particular, rice, cereals, and sugarcane are more preferable because they volatilize aromas when heated.

[0032] The materials preferably used as the aroma source material are substances that emit aromas from themselves and substances that emit aromas by heating, and plants and processed products obtained by drying, fermenting, etc. them are preferable. The aroma source materials can be roughly classified into tobacco of the genus Nicotiana of the Solanaceae family, the above-ground stems and leaves of plants of the same genus, and their components, as well as the flowers, roots, rhizomes, trunk branches, seeds, fruits, and above-ground stems and leaves of angiosperms, as well as teas, spore plants, sprouting vegetables, and fermented products of grains and beans. It is more preferable to mix two or more aroma source materials, and it is more preferable to mix three or more materials including a material having a fragrance defined as an aroma wafting from the aroma source material itself, a material having an aroma defined as an aroma wafting in the space by heating the aroma source material, and a material having a flavor defined as an aroma wafting in the mouth by heating the aroma source material. Specific examples thereof are listed below.

[0033] Tobacco of the genus Nicotiana of the Solanaceae family, the above-ground stems and leaves of plants of the same genus, and their components are desired to be used in the smallest possible amount from the viewpoint of inhaling harmful substances. However, for smokers of cigarettes etc., they tend to strongly seek aromas such as nicotine, and the minimum necessary use is preferable.

[0034] Since non-tobacco plants hardly need to consider attracting harmful substances, they are selected based on the fragrance of the plant itself and the fragrance volatilized by heating. Regarding the flowers of angiosperms, among the countless flowers of angiosperms, there are artichokes, ginger, chamomile, dandelions, chrysanthemums of the genus Chrysanthemum (such as Chrysanthemum morifolium Ramat., Chrysanthemum indicum L., Chrysanthemum zawadskii Herbich, Chrysanthemum boreale Makino, Chrysanthemum seticuspe Maxim.), aralia, honeysuckle, plants of the genus Dianthus of the family Caryophyllaceae (such as Dianthus japonicus Thunb., Dianthus amurensis Jacq., Dianthus chinensis L., Dianthus superbus L.), plants of the genus Mentha of the family Lamiaceae (such as Mentha canadensis L., Mentha arvensis L., Mentha spicata L., Mentha aquatica L., Mentha corsica Loisel., Mentha pulegium L.), various spearmint plants of the genus Mentha of the family Lamiaceae (such as Mentha spicata L., Mentha longifolia (L.)

However, the flowers may preferably be not only the flowers at the time of blooming but also flower buds. Also, it is not necessary to use all the parts constituting the flower, and only parts with a particularly strong fragrance such as petals, pistils, stamens, etc. can be used.

Among them, from the perspective of aroma, black tea is the most preferred.

[0044] Examples of spore plants include mushrooms, mosses, seaweeds, and ferns, all of which are extremely diverse. However, the following plants are preferably used.

[0046] Finally, fermented products of grains or beans are quite limited, and kouji, natto, and shinkiku are preferred.

[0047] The aerosol former preferably contains at least one selected from propylene glycol, 1,3 - butanediol, sorbitol, ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, glycerin, lactic acid, monoacetin (glycerin monoacetate), diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanedioate, dimethyl tetradecanedioate. In particular, propylene glycol, glycerin, and a mixture of propylene glycol and glycerin are preferred.

[0048] It is preferable to add a cooling agent and cross - linked PVP to the heat - generating aromatic substrate containing at least such an aromatic source material, an aerosol former, and a binder. This is because the flavor in the mouth due to the volatile components of the cooling agent brings about a refreshing smoking experience. And cross - linked PVP has the function of adsorbing the cooling agent and can prevent the cooling agent from dissipating over time. Moreover, just by providing a step of mixing the cooling agent dissolved in a lower alcohol with cross - linked PVP, the cooling agent is adsorbed by cross - linked PVP, so the step for adsorbing it to cyclodextrin is unnecessary.

[0049] As cooling agents, menthol, and menthol derivatives such as menthyl ether, menthyl ester, and menthyl carbonate, and menthone and its derivatives, and methane and its derivatives, and N-ethylamide of methanecarboxylic acid [WS3], ethyl ester of Nα-(methanecarbonyl)glycine [WS5], N-(4-cyanophenyl)amide of methanecarboxylic acid, N-(4-cyanomethylphenyl)amide of methanecarboxylic acid, and methanecarboxylic acid amides such as N-(alkoxyalkyl)amide of methanecarboxylic acid, and 2,3-dimethyl-2-(2-propyl)-butyric acid derivatives such as amide of methyldiisopropylpropionate [2,3-dimethyl-2-(2-propyl)-butyric acid-N-methylamide [WS23]], and isopulegol and its esters such as (l(-)-isopulegol, (l(-)-isopulegol acetate, N-(2-(pyridin-2-yl)ethyl)-3-p-menthanecarboxamide, (1R,2S,5R)-N-(4-methoxyphenyl)-5-methyl-2-(1-isopropyl)cyclohexane-carboxamide [WS12], and carboxamides such as oxamate, and L-carvone, xylitol, thymol, spiranol, etc. can be used. In particular, menthol and / or xylitol produce a flavor that lingers in the mouth suitable for smoking a heated aromatic cartridge using a heated smoking device.

[0050] Furthermore, the heated aroma-generating base material preferably contains microcrystalline cellulose. Microcrystalline cellulose is high-purity microcrystalline cellulose obtained by hydrolyzing and purifying pulp with an acid. It is a powdery substance with fluidity that does not dissolve in solvents such as water and ethanol and is used as an excipient for pharmaceutical tablet molding. This is because due to the large fluidity and high compressibility with large volume changes of microcrystalline cellulose, it is effective in preventing aggregation breakdown and adhesion to the mold in the molding of tablets by the direct compression method. Also in the present invention, by adding microcrystalline cellulose, the aroma source material and the aerosol former are homogeneously mixed and dispersed via the binder, so that in the production of a sheet of the heated aroma-generating base material using, for example, a three-roll mill that can be formed into a sheet by compression and shearing, aggregation breakdown of the sheet and adhesion to the metal roll can be effectively prevented.

[0051] Moreover, since it does not absorb solvents such as water and ethanol and exists in the form of powder in the heated aroma-generating base material, it is possible to reduce the time-dependent volume shrinkage due to drying etc. of the heated aroma-generating base material. In addition, it acts as a reinforcing material and can improve the strength of the heated aroma-generating base material. Therefore, it is possible to prevent the heated aroma-generating base material from falling off, dropping, and deforming before and after smoking and after long-term storage.

[0052] The heated aroma-generating base material needs to contain at least an aroma source material, an aerosol former, and a binder. However, for these to be homogeneously mixed and dispersed, and for the binding force to be enhanced to have the toughness and strength required for molding processing, there is a specific blending ratio, which has been experimentally determined from among numerous blending ratios. That is, it has been found that the aroma source material and the aerosol former need to be contained in the heated aroma-generating base material at 30 to 90% by mass and 10 to 40% by mass, respectively, and the binder needs to contain 1 to 30 parts by mass and 0.1 to 5 parts by mass of the first binder and the second binder, respectively, per 100 parts by mass of the aroma source material. It has also been found that further containing 1 to 25 parts by mass of cellulose fibers per 100 parts by mass of the aroma source material can further improve the quality.

[0053] By appropriately blending an appropriate amount of a cooling agent and crosslinked PVP into such a basic composition of the heatable aroma-generating substrate, and also by adding an appropriate amount and appropriate microcrystalline cellulose, the quality of the heatable aroma-generating substrate can be further improved as described above.

[0054] In order to experience the cooling sensation of the cooling agent and prevent its dissipation over time, the cooling agent and crosslinked PVP are required to have a content of 1 to 10% by mass and 2 to 10% by mass, respectively, in the heatable aroma-generating substrate, and the crosslinked PVP is required to have a content of 1 to 6 times the content of the cooling agent. Also, the mixing of the cooling agent and crosslinked PVP needs to be carried out by dissolving the cooling agent in a lower alcohol and then mixing it with the crosslinked PVP. In such a content and mixing method, the aroma of the cooling agent during smoking can be enjoyed, the crosslinked PVP adsorbs the cooling agent, and the continuous dissipation of these can be prevented. A quantitative index that can determine whether the heatable aroma-generating substrate has this dissipation prevention effect was found by comparing and studying the heatable aroma substrate of the present invention using menthol as the cooling agent with a conventional heatable aroma-generating substrate. This is defined as the menthol reduction rate d = {(d(24) - d(48)} / d(0), where d(0) is the content of menthol in the heatable aroma-generating substrate accurately weighed to about 5 g to 10 g in an environment of 17°C and 65% RH, d(24) is the mass of the accurately weighed heatable aroma-generating substrate after being left at 5°C for 24 hours, and d(48) is the mass of the heatable aroma-generating substrate after being left at 5°C for 48 hours. When d ≦ 0.20, the dissipation prevention effect of menthol becomes remarkable. Therefore, the heatable aroma-generating substrate of the present invention is characterized in that its menthol reduction rate d satisfies d ≦ 0.20. And the cooling agents already exemplified exhibit the dissipation prevention effect of the cooling agent by the above-mentioned blending amount and blending method.

[0055] Microcrystalline cellulose can improve the strength of the heat-generating aromatic substrate, effectively prevent the heat-generating aromatic substrate from falling off, dropping, deforming, etc. before and after smoking and after long-term storage, and can effectively prevent the agglomeration failure of the sheet and adhesion to the metal roll in the sheet production of the heat-generating aromatic substrate by the compression-shearing processing method. Therefore, it is necessary to contain 2 to 15% by mass in the heat-generating aromatic substrate. By being within this content range, such effects of microcrystalline cellulose can be achieved. Furthermore, it is more effective when the microcrystalline cellulose has an average particle diameter of 70 μm or more and 120 μm or less and / or a mass average molecular weight (Mw) of 20,000 or more and 60,000 or less, a sieve residue amount of 250 μm opening of 8% by mass or less with respect to the total amount of microcrystalline cellulose, and a sieve residue amount of 75 μm opening of 45% by mass or more with respect to the total amount of microcrystalline cellulose, that is, a microcrystalline cellulose with a narrow particle size distribution.

[0056] Since microcrystalline cellulose does not dissolve in water, lower alcohols, aerosol formers, etc., it can be treated in the same way as the aroma source material. Therefore, it is preferable to mix microcrystalline cellulose with the aroma source material and the aerosol former.

[0057] In the present invention, microcrystalline cellulose can improve the strength of the heated aroma-generating substrate, prevent the heated aroma-generating substrate from falling off, dropping, deforming, etc. before and after smoking and after long-term storage, and can also prevent the agglomeration failure of the sheet and adhesion to the metal roll in the production of the sheet of the heated aroma-generating substrate by the compression-shearing processing method. A quantitative index has been found that can determine whether the heated aroma-generating substrate has this effect. The first quantitative index is the shape change rate that occurs between the heated aroma-generating substrate before drying with a shape of 50 mm in length, 15 mm in width, and 0.3 mm in thickness and the heated aroma-generating substrate after drying the heated aroma-generating substrate with the same shape at 105°C for 10 minutes. The second quantitative index is the shape change rate that occurs between the heated aroma-generating substrate before drying with a shape of 50 mm in length, 15 mm in width, and 0.3 mm in thickness and the heated aroma-generating substrate after drying the heated aroma-generating substrate with the same shape at 105°C for 15 minutes. The third quantitative index is the shape change rate that occurs between the heated aroma-generating substrate before drying with a shape of 12 mm in length, 1.5 mm in width, and 0.3 mm in thickness and the heated aroma-generating substrate after drying the heated aroma-generating substrate with the same shape at 105°C for 10 minutes. The fourth quantitative index is the shape change rate that occurs between the heated aroma-generating substrate before drying with a shape of 12 mm in length, 1.5 mm in width, and 0.3 mm in thickness and the heated aroma-generating substrate after drying the heated aroma-generating substrate with the same shape at 105°C for 15 minutes. As a result of comparative study between the heated aroma-generating substrate of the present invention and the conventional heated aroma-generating substrate, it has been found that the heated aroma-generating substrate with these shape change rates below a certain limit value exhibits the desired strength, the prevention effect of the heated aroma-generating substrate from falling off, dropping, deforming, etc. before and after smoking and after long-term storage, and the prevention effect of the agglomeration failure of the sheet and adhesion to the metal roll in the compression-shearing processing method. Hereinafter, the allowable ranges of the change rates of the length, width, and thickness are shown as the specific shape change rates of the first to fourth quantitative indexes.

[0058] The first quantitative index of the heated aroma - generating substrate of the present invention uses a heated aroma - generating substrate with a shape of length 50 mm, width 15 mm, and thickness 0.3 mm.

When the length, width, and thickness of the heated aroma - generating substrate after 15 minutes of drying at 105°C are set as L15mm, W15mm, and T15mm respectively, the length change rate Lb (%) = { (L0 - L15) / L0}×100, the width change rate Wb (%) = { (W0 - W15) / W0}×100, and the thickness change rate Tb (%) = { (T0 - T15) / T0}×100 are defined, and it is characterized by satisfying 0%≦Lb≦8.1%, 0%≦Wb≦6.1%, 0%≦Tb≦1.5%, and 0%≦Vb≦14.3% respectively.

[0060] The third quantitative index of the heated aroma-generating base material of the present invention uses a heated aroma-generating base material in the shape of 12 mm in length, 1.5 mm in width, and 0.3 mm in thickness. The length, width, thickness, and volume of the heated aroma-generating base material before drying are set as L’0 (=12 mm), W’0 (=1.5 mm), and T’0 (=0.3 mm), respectively. When the length, width, and thickness of the heated aroma-generating base material after 10 minutes of drying at 105°C are set as L’10mm, W’10mm, and T’10mm, respectively, the length change rate L’a (%) = {(L’0 - L’10) / L’0}×100, the width change rate W’a (%) = {(W’0 - W’10) / W0}×100, and the thickness change rate T’a (%) = {(T’0 - T’10) / T’0}×100 are defined, and it is characterized by satisfying 0%≦L’a≦4.8%, 0%≦W’a≦5.0%, and 0%≦T’a≦1.2%, respectively.

[0061] The fourth quantitative index of the heated aroma-generating base material of the present invention uses a heated aroma-generating base material in the shape of 12 mm in length, 1.5 mm in width, and 0.3 mm in thickness. The length, width, thickness, and volume of the heated aroma-generating base material before drying are set as L’0 (=12 mm), W’0 (=1.5 mm), and T’0 (=0.3 mm), respectively. When the length, width, and thickness of the heated aroma-generating base material after 15 minutes of drying at 105°C are set as L’15mm, W’15mm, and T’15mm, respectively, the length change rate L’b (%) = {(L’0 - L’15) / L’0}×100, the width change rate W’b (%) = {(W’0 - W15) / W’0}×100, and the thickness change rate T’b (%) = {(T’0 - T15) / T’0}×100 are defined, and it is characterized by satisfying 0%≦L’b≦5.8%, 0%≦W’b≦5.1%, and 0%≦T’b≦1.5%, respectively.

[0062] As described above, regarding the heated aroma-generating base material of the present invention, the constituent components, formulations, and characteristics have been described. However, as already described therein, the characteristics of the heated aroma-generating base material are affected by the manufacturing method. Therefore, it is also an object of the present invention to provide a manufacturing method preferable for a high-quality heated aroma-generating base material.

[0063] First, the method for manufacturing the heatable aroma-generating base material of the present invention comprises a first mixing step of mixing an aroma source material, an aerosol former, and a first binder, a second mixing step of mixing a second binder into the mixture produced in the first mixing step, and a forming step of forming the mixture produced in the second mixing step into a heatable aroma-generating base material. Although the reason why such a manufacturing process of mixing different binders step by step is preferable is not clear, as already explained, the cellulose-based first binder promotes the uniform mixing and dispersion of the aroma source material and the aerosol former to form a stable sol state, and then the polysaccharide-based second binder is considered to form a gel state that enhances these bindings.

[0064] Second, the method for manufacturing the heatable aroma-generating base material of the present invention comprises a first mixing step of mixing an aroma source material, an aerosol former, and a first binder, and a mixing and forming step of forming the mixture produced in the first mixing step into a heatable aroma-generating base material while mixing a second binder. This is because according to the compression-shear forming process, the second binder can be uniformly mixed and dispersed, and it can be formed into a sheet-like heatable aroma-generating base material, so that the above-mentioned second mixing step can be omitted, and the manufacturing process can be shortened.

[0065] Thirdly, the method for manufacturing the heatable aroma-generating base material of the present invention is characterized by providing a curing step of curing the mixture produced in the first mixing step immediately after the first mixing step. In particular, this curing step is preferably carried out at a temperature of 15°C or higher and 30°C or lower for a time of 72 hours or longer and 336 hours or shorter. As already explained, this curing step is presumed to have the effect of increasing and stabilizing the degree of dispersion of the aroma source material in the sol state formed by promoting the uniform mixing and dispersion of the cellulose-based first binder, the aroma source material, and the aerosol former. This is because an increase in the volume of the mixture is observed in the curing step. When the temperature is less than 15°C, the volume increase is also slight, and the effect of the curing step on the quality of the heatable aroma-generating base material is not recognized. When the temperature exceeds 30°C, although the cause is unknown, gelation of the mixture is observed. Also, when the time is less than 72 hours, the volume increase is also slight, and the effect of the curing step on the quality of the heatable aroma-generating base material is not recognized. When the time exceeds 336 hours, this volume increase stops, the effect of the curing step on the quality of the heatable aroma-generating base material saturates, and further long-term curing may cause gelation.

[0066] Fourthly, the method for manufacturing the heatable aroma-generating base material of the present invention is characterized by comprising a third mixing step of mixing an aroma source material, an aerosol former, a first binder, and a second binder, a curing step (Y) of curing the mixture produced in the third mixing step, and a shaping step of shaping the mixture produced in the curing step into the heatable aroma-generating base material. When passing through the curing step, it is not necessary to add the first binder and the second binder step by step. A third mixing step of mixing the aroma source material, the aerosol former, the first binder, and the second binder can be provided, and a manufacturing process can be adopted in which a curing step of curing the mixture produced in the third mixing step is provided. In this curing step, it is considered that the effect of increasing the degree of dispersion of the aroma source material by the first binder and the effect of increasing the binding by the second binder occur in parallel.

[0067] Fifthly, in the method for manufacturing the heatable aroma-generating base material of the present invention, when a cooling agent is added to the heatable aroma-generating base material in the manufacturing methods described first to fourth, a fourth mixing step of mixing crosslinked PVP into a lower alcohol solution of the cooling agent is added in order to mix the cooling agent in the first mixing step, the second mixing step, the third mixing step, and the mixing and molding step.

[0068] Finally, the heatable aroma source and the heatable aroma cartridge of the present invention using the high-quality heatable aroma-generating base material of the present invention manufactured by the above-described components, formulations, and methods will be described.

[0069] The heatable aroma source constituting the heatable aroma cartridge of the present invention is characterized by being a single heatable aroma-generating base material or an aggregate of heatable aroma-generating base materials. In the case of a single unit, it is preferable that the heatable aroma source is in the form of a sheet. In the case of an aggregate, it is preferable that a suitable amount of sheet-shaped or cut heatable aroma-generating base materials are bundled. In particular, the shape of the cut heatable aroma-generating base material is not limited to prismatic, flat plate-shaped, cylindrical, granular, etc., but from the viewpoint of forming a gas flow path, it is preferably prismatic. However, in either the sheet form or the prismatic form, in order to more sufficiently secure a gas flow path, it is required to be a heatable aroma source in which the heatable aroma-generating base material is arranged such that voids communicate in the major axis direction of the heatable aroma cartridge provided with the heatable aroma source.

[0070] Such a heated aroma source may be directly stored in an outer member that wraps the entire heated aroma cartridge, or may be wrapped with a heated aroma generating substrate wrapping member that is a cylindrical roll. In the former case, the heated aroma generating substrate will be packed into the outer member, but in the latter case, for example, it only needs to be wrapped with the outer member, which is efficient in manufacturing the heated aroma cartridge. As the heated aroma generating substrate wrapping member, the paper of the prior art can be used, but in the case of a heating type smoking device equipped with a blade type heat source by a heater, since it does not come into contact with the heat source and aerosol former resistance of the heated aroma generating substrate is required, a plastic film is more suitable. In particular, from the viewpoint of environmental protection, it is more preferable that it is a biodegradable plastic film. Examples of plastics include plastics such as polyolefin, polyester, nylon, and engineering plastics, and examples of biodegradable plastics include poly(3-hydroxybutyrate) (PHB), poly(ε-caprolactone) (PCL), poly(butylene succinate) (PBS), poly(L-lactide) (PLA ) etc. can be mentioned. However, in the case of an omnidirectional heat source by electromagnetic induction heating, since the entire heated aroma source of the heated aroma cartridge is heated up to about 240°C, when using plastic as the heated aroma generating substrate wrapping member, heat resistance equivalent to that of cellulose fibers (constituting paper) where glass transition or thermal decomposition starts at about 300°C, that is, a film of a special engineering plastic having a glass transition temperature of 240°C or higher needs to be applied. Examples of such special engineering plastics include polyamideimide, polyarylate, polyimide, polytriazine, liquid crystal polymer, etc.

[0071] Next, the heated aroma generating cartridge of the present invention is characterized in that the heated aroma generating source is housed in a heated aroma cartridge outer member which is a cylindrical body, and the heated aroma cartridge outer member itself forms a mouthpiece. Unlike a paper cigarette, the heated aroma cartridge does not necessarily require a filter member for filtering harmful components such as carbon monoxide, nicotine, tar, etc. and off-flavor components contained in the gaseous and particulate components of the smoke generated by the combustion of tobacco leaves and rolling paper. Therefore, the mouthpiece may be simply a cavity. However, since the heated aroma cartridge outer member which is a cylindrical body needs to have sufficient strength to be held in the mouth, it is more preferably made of thick paper, plastic or engineering plastic with an appropriate thickness, and from the viewpoint of environmental protection, it is even more preferably a biodegradable plastic film. As the plastic and biodegradable plastic, those mentioned for the heated aroma generating base wrapping member can be used. However, this is also applicable to a heating type smoking device equipped with a blade type heat source by a heater, but in the case of an omnidirectional heat source by electromagnetic induction heating, since the entire heated aroma generating source of the heated aroma cartridge is heated up to about 240°C, when using plastic as the heated aroma cartridge outer member, as already described, it is necessary to apply a special engineering plastic having a glass transition temperature of 240°C or higher.

[0072] Also, the heated aroma cartridge of the present invention can be configured such that the mouthpiece is attached in the longitudinal direction of the heated aroma generating source and is housed in a heated aroma cartridge outer member which is a cylindrical body. For the same reason, the mouthpiece may be simply a hollow tube. In this case, as the heated aroma cartridge outer member, thin paper used for conventional paper cigarettes can be used, but the hollow tube is more preferably made of thick paper, plastic or engineering plastic with an appropriate thickness, and from the viewpoint of environmental protection, it is even more preferably a biodegradable plastic film. Also in this case, as already described, it is necessary to select a plastic according to the heat source for the heated aroma cartridge outer member.

[0073] In any of these mouthpieces, it is preferable to include at least one of a support member for preventing the movement of the heated aroma generation source toward the mouthpiece due to smoking, a cooling member for actively cooling the volatiles of the aerosol former to increase the amount of aerosol generated, and a filter member for filtering carbon monoxide, nicotine, tar, etc. and off-flavor components generated by heating the heated aroma generation source.

[0074] Furthermore, in any of these mouthpieces, the flavor of the heated aroma cartridge can be adjusted in various ways by arranging the support member and the cooling member in this order longitudinally from the side of the heated aroma generation source, the support member and the filter member in this order longitudinally from the side of the heated aroma generation source, the cooling member and the filter member in this order longitudinally from the side of the heated aroma generation source, or the support member, the cooling member, and the filter member in this order longitudinally from the side of the heated aroma generation source.

[0075] The mouthpiece provided with at least one or more selected from the support member, the cooling member, and the filter member can be directly attached to the outer member of the heated aroma cartridge, but it is preferably configured to be pre-wound with a mouthpiece wrapping member which is a cylindrical roll, so that the heated aroma cartridge can be easily assembled. Also, the support member, the cooling member, and the filter member selected for attachment to the mouthpiece may be individually wound with a mouthpiece wrapping member which is a cylindrical roll. For such members to which the temperature of the heat source is not transmitted, it is possible to replace the conventionally used paper with plastic or engineering plastic, and in particular, it is preferably biodegradable plastic.

[0076] Furthermore, forming at least one or more holes on the outer peripheral surface of the mouthpiece is also an effective means for adjusting the flavor, suction amount, etc. of the heated aroma cartridge.

Advantages of the Invention

[0077] According to the heated aroma generating substrate of the present invention, when detaching a heated aroma cartridge equipped with a heated aroma source composed thereof from a heat-not-burn smoking device, problems such as deformation, detachment, and dropping of the heated aroma generating substrate do not occur. In smoking, the aroma volatilized from the heated aroma source material can be fully enjoyed. In the production of the heated aroma generating substrate, the aroma source material, aerosol former, and binder are uniformly dispersed and bound, and it has the toughness and strength required for molding processing, so stable production is possible.

[0078] Further, the heated aroma generating substrate of the present invention is characterized in that when a cooling agent such as menthol or xylitol is added as an aromatic agent, the dissipation of the cooling agent over time is suppressed. Even after storing a heated aroma cartridge equipped with a heated aroma generating source containing the same for a long period of time, when it is attached to a heat-not-burn smoking device and smoked, the aroma of the heated aroma generating substrate can be fully enjoyed.

[0079] Furthermore, the heated aroma generating substrate of the present invention is characterized by having little dimensional change due to drying. Even after smoking by attaching a heated aroma cartridge equipped with a heated aroma generating source composed thereof to a heat-not-burn smoking device, there is no detachment or dropping of the heated aroma generating substrate from the heated aroma cartridge. Even after long-term storage, there is no detachment or dropping of the heated aroma generating substrate from the heated aroma cartridge, it has excellent handleability, and has the effect of preventing contamination of the heat source of the heat-not-burn smoking device.

Embodiments for Carrying Out the Invention

[0081] Hereinafter, the present invention will be described in more detail with reference to Examples, Comparative Examples, and figures, but the present invention is not limited thereto, and various modifications can be made and implemented within the scope not departing from the gist of the present invention and is limited only by the technical idea described in the claims is.

[0082] First, in order to specifically show the influence of the type of binder and its addition method, Experiments of Examples 1 to 10 and Comparative Examples 1 to 4 were conducted. ≪Example 1≫

[0083] Using the method shown in FIG. 9 in which methylcellulose and sodium carboxymethylcellulose (CM C), which are the first binders, and glucomannan, which is the second binder, are mixed step by step, a heatable aroma-generating base material was produced. Xylitol as a cooling agent was added in the first mixing step. For this purpose, an aqueous xylitol solution was 100 parts by mass of xylitol 400 parts by mass of water were mixed and stirred to produce.

[0084] On the other hand, the tea leaves and amacha vine leaves, which are aroma source materials, were dried at 70° C. so that the water content became about 2% by mass, then pulverized, and those that passed through an 80-mesh sieve were used. Drying temperature is preferably in the range of 60°C or higher and 80°C or lower. Within this temperature range, it is easy to reach the desired moisture content while avoiding the dissipation of the required fragrance components. Furthermore, it is more preferably 65°C or higher and 75°C or lower. Also, in order to facilitate the dispersion in the first mixing step, the dry pulverized material needs to absorb moisture, and the moisture content is preferably 5% by mass or less, more preferably 3% by mass or less, and even more preferably 0.1% by mass or more.

[0085] In the first mixing step shown in FIG. 9, 80 parts by mass of dry pulverized black tea leaves 20 parts by mass of dry pulverized ama-cha-zuru leaves 30 parts by mass of glycerin 30 parts by mass of propylene glycol 15 parts by mass of methylcellulose 4 parts by mass of sodium carboxymethylcellulose (CMC) 8 parts by mass of xylitol / aqueous solution were put into a mixer and mixed for 15 minutes to produce a first mixture.

[0086] This first mixture was put into a mixing and forming step that also serves as a second mixing step of mixing with a second binder and a first forming step of forming into a sheet-shaped heat-generating aromatic substrate. In this mixing and forming step, while adding 0.5 part by mass of glucomannan, which is a second binder, and 20 parts by mass of water to 100 parts by mass of the first mixture, a three-roll mill that presses a doctor blade against a roll to form it into a sheet was repeated, and a second mixture, which is a composition of the heat-generating aromatic substrate, was produced and at the same time, it was formed into a sheet-shaped heat-generating aromatic substrate. In Example 1, in this mixing and forming step, moisture evaporated moderately, and it was formed into a sheet-shaped heat-generating aromatic substrate with a thickness of 0.3 mm. ​​​​​The three-roll mill with adjusted roll spacing, roll speed ratio, etc. was run 8 times so as to be shaped. This mixing and forming step serves also as the second mixing step ( a step of mixing 100 parts by mass of the first mixture, 0.5 part by mass of glucomannan as the second binder, and 20 parts by mass of water) and the first forming step of forming into a sheet shape by a three-roll mill in the manufacturing method shown in FIG. 8, and there is an advantage that the manufacturing process shown in FIG. 8 can be simplified. However, there is no difference in the mixing and dispersion states of the heated aromatic generating base materials in the resulting sheet shape.

[0087] Next, in the second forming step shown in FIG. 9, this sheet is cut into a rectangle of 150 mm in length and 240 mm in width, and finally, using a rotary cutter, it is cut into a shape of 240 mm in length, 1.5 mm in width, and 0.3 mm in thickness, and a long prismatic heated aromatic generating base material is manufactured. The longitudinal and transverse directions of this sheet are parallel and perpendicular to the rotation axis of the roll, respectively.

[0088] Fifty long prismatic heated aromatic generating base materials 3211 (FIG. 3) manufactured in this way are aligned in the longitudinal direction, and then wound and pasted using paper with a basis weight of 34 g / m2 as the heated aromatic generating base material wrapping member 322, and after a cylindrical roll is manufactured with an outer diameter of 6.9 mm, it is cut to a length of 12.0 mm, and a heated aromatic generating source 320 is manufactured. As a result, the heated aromatic generating source 320 in which 50 heated aromatic generating base materials 3211 (FIG. 3) of 12.0 mm in length, 1.5 mm in width, and 0.3 mm in thickness are wound around paper contains a heated aromatic generating base material aggregate 321 of 0.29 g per heated aromatic generating source 320, and the volume filling ratio of the heated aromatic generating base material aggregate 321 (FIG. 3) to the volume of the heated aromatic generating source 320 is 0.60. ​ It was. Also, with respect to 100 parts by mass of the aroma source material, the aerosol former was 60 parts by mass, methyl cellulose and CMC which are the first binders were 15 parts by mass and 4 parts by mass respectively, and glucomannan which is the second binder was 0.9 part by mass in the heat-generating aromatic generating base material 3211 (FIG. 3). were included.

[0089] Here, the heat-generating aromatic generating base material wrapping member 322 for wrapping the heat-generating aromatic generating base material aggregate 321 does not necessarily have to be paper, and a plastic film having a strength equivalent to that of paper with a basis weight of 30 g / m2 to 40 g / m2 can be used. As will be described later, the heat-generating aromatic generating base material wrapping member 322 does not come into contact with the heat source of the heat-not-burn smoking device and comes into contact with the aerosol former which is also an organic solvent contained in the heat-generating aromatic generating base material 3211 (FIG. 3). Therefore, it is preferable to use a plastic film having a strength equivalent to that of each paper. In particular, from the viewpoint of environmental protection, it is more preferable to use a biodegradable plastic film. However, in the case of a plastic film, it is necessary to select a film thickness according to the material. The same applies to the heat-generating aromatic generating base material wrapping members in the following Examples and Comparative Examples. However, this is a selectable material for the heat-generating aromatic cartridge used by being attached to a heat-not-burn smoking device equipped with a board-type heat source.

[0090] In Examples 1 to 5 and Comparative Examples 1 and 2, the heat-generating aromatic generating sources with such an outer diameter and length are processed for use as a heat-not-burn smoking device with an Icos (registered trademark, manufactured by Philip Morris) equipped with a heater-based board-type heat source in the smoking test described later. ≪Example 2≫ ​​​​​​​​​​​​​​​

[0091] Example 2 has the exact same composition as Example 1. However, to specifically demonstrate the curing effect, a heated aroma-generating base material was manufactured according to the manufacturing process with the additional curing process shown in FIG. 10. Up to the first mixing process, the first mixture was manufactured in the same manner as in Example 1. However, before the mixing and molding process that also serves as the second mixing process and the first molding process, the first mixture was sealed in a polyethylene bag, and a curing process at 20 °C for 144 hours (6 days) was provided. By undergoing this curing process, the apparent volume became approximately 1.5 times, and it was visually observed that the cured mixture after the curing process had less release of the pulverized tea compared to before curing. From this phenomenon, it is considered that the dispersion of the aroma source material, aerosol former, and the first binders methyl cellulose and CMC became better due to curing. The cured mixture thus manufactured, like in Example 1, underwent the mixing and molding process and the second molding process, and the heated aroma-generating source 320 was manufactured. As a result, 50 heated aroma-generating base material aggregates 321 with a length of 12.0 mm, a width of 1.5 mm, and a thickness of 0.3 mm wound around a paper-made heated aroma-generating base material wrapping member 322, the heated aroma-generating source 320 contained 0.29 g of the heated aroma-generating base material aggregate 321 per heated aroma-generating source 320, and the volume filling rate of the heated aroma-generating base material aggregate 321 with respect to the volume of the heated aroma-generating source 320 was 0. 60. Also, like in Example 1, the heated aroma-generating base material 3211 (FIG. 3) had 60 parts by mass of aerosol former, 15 parts by mass and 4 parts by mass of the first binders methyl cellulose and CMC, respectively, with respect to 100 parts by mass of the aroma source material, and the second binder glue

[0092] The cured mixture thus manufactured, like in Example 1, underwent the mixing and molding process and the second molding process, and the heated aroma-generating source 320 was manufactured. As a result, 50 heated aroma-generating base material aggregates 321 with a length of 12.0 mm, a width of 1.5 mm, and a thickness of 0.3 mm wound around a paper-made heated aroma-generating base material wrapping member 322, the heated aroma-generating source 320 contained 0.29 g of the heated aroma-generating base material aggregate 321 per heated aroma-generating source 320, and the volume filling rate of the heated aroma-generating base material aggregate 321 with respect to the volume of the heated aroma-generating source 320 was 0. 60. Also, like in Example 1, the heated aroma-generating base material 3211 (FIG. 3) had 60 parts by mass of aerosol former, 15 parts by mass and 4 parts by mass of the first binders methyl cellulose and CMC, respectively, with respect to 100 parts by mass of the aroma source material, and the second binder glue was 60. Also, like in Example 1, the heated aroma-generating base material 3211 (FIG. 3) had 60 parts by mass of aerosol former, 15 parts by mass and 4 parts by mass of the first binders methyl cellulose and CMC, respectively, with respect to 100 parts by mass of the aroma source material, and the second binder glue was It contains 0.9 parts by mass of glucomannan. <Comparative Example 1>

[0093] Comparative Example 1 is to specifically show the effect of the two-stage divided addition of the first binder and the second binder. Glucomannan, which is the second binder, was mixed simultaneously with methylcellulose and CMC, which are the first binders, in the first mixing step instead of the mixing and molding step of Example 1. A heatable aroma source was produced in the same manner as in Example 1, except for this. The xylitol aqueous solution for introducing xylitol as a cooling agent in the first mixing step

[0094] was prepared by mixing and stirring 100 parts by mass of xylitol 400 parts by mass of water On the other hand, the tea leaves and the leaves of the amacha vine, which are aroma source materials, were dried at 70 °C, pulverized, and those that passed through an 80-mesh sieve were used. Incidentally, the moisture content of these dried and pulverized products was about 2% by mass.

[0095] In the first mixing step, 80 parts by mass of the dried and pulverized tea leaves 20 parts by mass of the dried and pulverized leaves of the amacha vine 30 parts by mass of glycerin 30 parts by mass of propylene glycol 15 parts by mass of methylcellulose 4 parts by mass of sodium carboxymethylcellulose (CMC) 0.9 parts by mass of glucomannan 8 parts by mass of the xylitol / aqueous solution 37 parts by mass of water

[0096] were put into a mixer and mixed for 15 minutes to produce a first mixture.

[0096] The first mixture thus produced is different from that of Example 1 in that the second binder is mixed. A three-roll mill that does not press the doctor blade against the roll to form it into a sheet shape is fed into a first forming step of repeating the three-roll mill, and the roll spacing and the speed ratio between the rolls are adjusted. The three-roll mill is repeated 8 times to form a sheet-shaped heated aromatic generating substrate with appropriately evaporated moisture and a thickness of 0.3 mm. Next, through the second forming step in the same manner as in Example 1, a heated aromatic generating source was produced. As a result, 50 heated aromatic generating substrate aggregates 321 with a length of 12.0 mm, a width of 1.5 mm, and a thickness of 0.3 mm were wound around a paper-made heated aromatic generating substrate wrapping member 322 to form a heated aromatic generating source 320. Each heated aromatic generating source 320 contains 0.29 g of a heated aromatic generating substrate aggregate 321, and the volume filling rate of the heated aromatic generating substrate aggregate 321 with respect to the volume of the heated aromatic generating source 320 is 0.60. Also, in the same manner as in Example 1, the heated aromatic generating substrate 3211 (Figure 3) contains 60 parts by mass of aerosol former, 15 parts by mass and 4 parts by mass of methyl cellulose and CMC which are the first binders, and 0.9 parts by mass of glucomannan which is the second binder with respect to 100 parts by mass of the aromatic source material. Example 3 specifically shows that the effect of the present invention does not depend on the cross-sectional shape perpendicular to the longitudinal direction of the heated aromatic generating substrate. Therefore, the width and thickness of the heated aromatic generating substrate were made smaller compared to Example 2. In exactly the same manner as in Example 2, through the first mixing step and the curing step, a second mixture is produced in a mixing and forming step that also serves as the second mixing step and the first forming step, and is formed into a sheet-shaped heated aromatic generating substrate. However, in Example 3, the position of the doctor blade, the roll spacing is formed into a sheet-shaped heated aromatic generating substrate with appropriately evaporated moisture and a thickness of 0.3 mm.

[0097] Next, through the second forming step in the same manner as in Example 1, a heated aromatic generating source was produced. As a result, 50 heated aromatic generating substrate aggregates with a length of 12.0 mm, a width of 1.5 mm, and a thickness of 0.3 mm are wound around a paper-made heated aromatic generating substrate wrapping member to form a heated aromatic generating source 320. Each heated aromatic generating source 320 contains 0.29 g of a heated aromatic generating substrate aggregate 321, and the volume filling rate of the heated aromatic generating substrate aggregate 321 with respect to the volume of the heated aromatic generating source 320 is 0.60. Also, in the same manner as in Example 1, the heated aromatic generating substrate 3211 (Figure 3) contains 60 parts by mass of aerosol former, 15 parts by mass and 4 parts by mass of methyl cellulose and CMC which are the first binders, and 0.9 parts by mass of glucomannan which is the second binder with respect to 100 parts by mass of the aromatic source material. Example 3 specifically shows that the effect of the present invention does not depend on the cross-sectional shape perpendicular to the longitudinal direction of the heated aromatic generating substrate. Therefore, the width and thickness of the heated aromatic generating substrate were made smaller compared to Example 2. In exactly the same manner as in Example 2, through the first mixing step and the curing step, a second mixture is produced in a mixing and forming step that also serves as the second mixing step and the first forming step, and is formed into a sheet-shaped heated aromatic generating substrate. However, in Example 3, the position of the doctor blade, the roll spacing ≪Example 3≫

[0098] Example 3 specifically shows that the effect of the present invention does not depend on the cross-sectional shape perpendicular to the longitudinal direction of the heated aromatic generating substrate. Therefore, compared with Example 2, the width and thickness of the heated aromatic generating substrate were made smaller. In exactly the same manner as in Example 2, through the first mixing step and the curing step, a second mixture is produced in a mixing and forming step that also serves as the second mixing step and the first forming step, and is formed into a sheet-shaped heated aromatic generating substrate. Next, through the second forming step in the same manner as in Example 1, a heated aromatic generating source was produced. As a result, 50 heated aromatic generating substrate aggregates with a length of 12.0 mm, a width of 1.5 mm, and a thickness of 0.3 mm and a three-roll mill in which adjustments different from those of Example 2 were made for the speed ratio between rolls, etc. This was repeated 8 times and formed into a sheet-like heated aromatic generating substrate with a thickness of 0.1 mm. Next, in the same manner as in Example 1, in the second forming step, after being cut into a rectangle with a length of 150 mm and a width of 240 mm, using a rotary cutter, it was cut into a shape with a length of 240 mm, a width of 1.0 mm, and a thickness of 0.1 m m, and a long prismatic heated aromatic generating substrate was manufactured.

[0099] In the case of this heated aromatic generating substrate, 225 pieces were aligned in the longitudinal direction, and then wrapped and enclosed with paper having a basis weight of 34 g / m 2, and after being pasted, a cylindrical roll with an outer diameter of 6.9 mm was manufactured and then cut to a length of 12.0 mm. As a result, 225 heated aromatic generating substrate aggregates 321 with a length of 12.0 mm, a width of 1.0 mm, and a thickness of 0.1 mm were wound around a paper-made heated aromatic generating substrate wrapping member 322 for the heated aromatic generating source 320. The heated aromatic generating source 320 contains 0.29 g of the heated aromatic generating substrate aggregate 321 per one heated aromatic generating source 320, and the volume filling ratio of the heated aromatic generating substrate aggregate 321 to the volume of the heated aromatic source 320 was 0.6 0. Of course, the composition of the heated aromatic generating substrate 3211 (FIG. 3) in this case is the same as that of Examples 1 and 2, and Comparative Example 1.

[0100] <<Example 4>> Example 4 also specifically shows that the effect of the present invention does not depend on the cross-sectional shape perpendicular to the longitudinal direction of the heated aromatic generating substrate. Therefore, the width and thickness of the heated aromatic generating substrate were increased compared to Example 2. In exactly the same manner as in Example 2, through the first mixing step and the curing step, a second mixture was produced in a mixing and forming step that also served as the second mixing step and the first forming step, and a sheet-like heated ​​​​​It was formed into a substrate for generating fragrance. However, in Example 4, the position of the doctor blade, the roll interval , and the speed ratio between the rolls, etc., were adjusted differently from those in Example 2, and a three-roll mill was repeated 8 times to form a sheet-like substrate for generating fragrance to be heated with a thickness of 0.5 mm. Next, similar to Example 1, in the second forming step, after being cut into a rectangle with a length of 150 mm and a width of 240 mm , it was cut into a shape with a length of 240 mm, a width of 2.0 mm, and a thickness of 0.5 m m using a rotary cutter, and a long prismatic substrate for generating fragrance to be heated was manufactured.

[0101] In the case of this substrate for generating fragrance to be heated, 23 pieces were aligned in the longitudinal direction, and then wound and wrapped around paper with a basis weight of 34 g / m 2, and glued to form a cylindrical roll with an outer diameter of 6.9 mm. After that, it was cut into a length of 12.0 mm. As a result, 23 substrates for generating fragrance to be heated 321 with a length of 12.0 mm, a width of 2.0 mm, and a thickness of 0.5 mm were wound around a paper-made substrate for generating fragrance to be heated wrapping member 322 to form a fragrance generation source 320 to be heated. Each fragrance generation source 320 to be heated contained a 0.30 g aggregate of the substrate for generating fragrance to be heated 321, and the volume filling ratio of the aggregate of the substrate for generating fragrance to be heated 321 to the volume of the fragrance generation source 320 to be heated was 0.62 . Of course, the composition of the substrate for generating fragrance to be heated 3211 (Figure 3) in this case was the same as that in Examples 1 and 2, as well as in Comparative Example 1. <Comparative Example 2>

[0102] In Comparative Example 2, in order to confirm the effect of the second binder, an attempt was made to manufacture a substrate for generating fragrance to be heated in the same manner as in Comparative Example 1 without using glucomannan. However, in the first forming step using a three-roll mill, breakage, peeling, etc. occurred, and it was difficult to form a sheet, and glucomannan ​It was found that it is an essential binder for the heated aroma generating base material and its production. However, for the smoking test, heated aroma generating sources of the same size as those in Examples 1 and 2 and Comparative Example 1 were produced. For the smoking test, heated aroma generating sources of the same size as those in Examples 1 and 2 and Comparative Example 1 were produced. were manufactured. ≪Example 5≫

[0103] In Example 5, in order to specifically show the magnitude of the curing influence, a curing process was added to the production process of Comparative Example 1. That is, the first mixture in Comparative Example 1 was sealed in a polyethylene bag and a curing process of 20 °C for 144 hours (6 days) was provided. After this curing process, the apparent volume became about 1.4 times, and it was visually observed that the cured mixture after the curing process had less free pulverized tea compared to before curing. Finally, it was molded in the same manner as in Example 1, and 50 heated aroma generating base material aggregates 321 with a length of 12.0 mm, a width of 1.5 mm, and a thickness of 0.3 mm were wound around a paper-made heated aroma generating base material wrapping material 322 to produce a heated aroma generating source 320.

[0104] In the above Examples 1 to 5, and Comparative Examples 1 and 2, for the evaluation using the Icos (registered trademark) of the blade type heat source by the heater in the smoking test described later, they were molded. In the above Examples 1 to 5, and Comparative Examples 1 and 2, for the evaluation using the Icos (registered trademark) of the blade type heat source by the heater in the smoking test described later, they were molded. However, due to the heat source, the heating method, the maximum achievable temperature, as well as the heated aroma generating source and the heated aromatic cartridge configuration, etc. are different, and it is considered that it may affect the evaluation results. Therefore, although it is the same heating type smoking device, an evaluation using the glow (registered trademark ) of the omnidirectional heat source by electromagnetic induction heating was also conducted. Examples 6 to 10, as well as Comparative Examples 3 and 4, Regarding the composition of the heated aroma generating substrate and its manufacturing method, respectively correspond to Examples 1 to 5, as well as Comparative Examples 1 and 2, but are formed into a heated aroma generating source corresponding to glow (registered trademark). . ≪Example 6≫

[0105] A sheet-like heated aroma generating substrate with a thickness of 0.3 mm, manufactured in exactly the same manner as Example 1, was cut into a rectangle with a length of 150 mm and a width of 210 mm in the second forming step, and then cut into a shape with a length of 210 mm, a width of 1.5 mm, and a thickness of 0.3 mm using a rotary -cutter, and a long prismatic heated aroma generating substrate was manufactured. .

[0106] Thirty-one of these heated aroma generating substrates were aligned in the longitudinal direction and then wound and wrapped with paper having a basis weight of 34 g / m2, and glued to form a cylindrical roll with an outer diameter of 5.5 mm. After being manufactured, it was cut to a length of 42.0 mm to produce a heated aroma generating source 420. As a result, 31 heated aroma generating substrates with a length of 42.0 mm, a width of 1.5 mm, and a thickness of 0.3 mm were wound around a paper-made heated aroma generating substrate wrapping member 422 to form a heated aroma generating source 420. The heated aroma generating source 420 contains 0.63 g of the heated aroma generating substrate aggregate per heated aroma generating source 420, and the volume of the heated aroma generating substrate aggregate relative to the volume of the heated aroma generating source 420. The heated aroma generating source 420 contains 0.63 g of the heated aroma generating substrate aggregate per heated aroma generating source 420, and the volume of the heated aroma generating substrate aggregate relative to the volume of the heated aroma generating source 420. The volume filling ratio of the body 421 was 0.59. There was no change in the composition of the heated aromatic generating base material, For 100 parts by mass of the aroma source material, 60 parts by mass of the aerosol former, and the first binder methyl cellulose and CMC were 15 parts by mass and 4 parts by mass respectively, and 0.9 parts by mass of glucomannan which is the second binder was included.

[0107] Here, the heated aromatic generating base material wrapping member 422 that wraps the heated aromatic generating base material aggregate 421 does not necessarily have to be paper, and a plastic film having a strength equivalent to that of paper with a basis weight of 30 g / m2 to 40 g / m2 can be used. However, in the case of an omnidirectional heat source by electromagnetic induction heating, unlike the blade-type heat source by a heater, the entire heated aroma generation source 420 and the outer member 410 of the heated aroma cartridge of the heated aroma cartridge are heated to about 240 °C, so a plastic film, an engineering plastic film, or a biodegradable plastic film cannot be used as a substitute for paper. In this case, when using plastic as the heated aroma generating base material wrapping member, heat resistance equivalent to that of cellulose fibers (constituting paper) where glass transition or thermal decomposition starts at about 300 °C, that is, a film of a special engineering plastic having a glass transition temperature of 240 °C or higher needs to be applied. Examples of such special engineering plastics include polyamideimide, polyarylate, polyimide, polytriazine, liquid crystal polymer, etc. can be mentioned.

[0108] ≪Example 7≫

[0108] Example 7 also specifically shows the curing effect compared to Example 6 in order to confirm the curing effect. A sheet-shaped heated aromatic generating base material with a thickness of 0.3 mm, manufactured in exactly the same manner as in Example 2, was, in the second forming step, after being cut in exactly the same manner as in Example 6, a heated aromatic source 4 20 was manufactured. As a result, 31 heated aromatic generating base material aggregates 421 with a length of 42.0 mm, a width of 1.5 mm, and a thickness of 0.3 mm were wound around a paper-made heated aromatic generating base material wrapping member 4 22. The heated aromatic generating source 420 thus formed contained 0.6 3 g of the heated aromatic generating base material aggregate 421 per heated aromatic generating source 420, and the volume filling ratio of the heated aromatic generating base material aggregate 421 to the volume of the heated aromatic generating source 420 was 0.59. The composition was the same as that of the heated aromatic generating base material in Example 6. <Comparative Example 3>

[0109] Comparative Example 3 was also manufactured in exactly the same manner as Comparative Example 1 for confirming the effect of the two-stage divided addition in order to specifically show the effect of the two-stage divided addition of the first binder and the second binder. A sheet-shaped heated aromatic generating base material with a thickness of 0.3 mm was, in the second forming step, cut in exactly the same manner as in Example 6 and then a heated aromatic source 420 was manufactured in exactly the same manner. As a result, 31 heated aromatic generating base material aggregates 421 with a length of 42.0 mm, a width of 1 .5 mm, and a thickness of 0.3 mm were wound around a paper-made heated aromatic generating base material wrapping member 422. The heated aromatic generating source 420 thus formed contained 0.63 g of the heated aromatic generating base material aggregate 421 per heated aromatic generating source 420, and the volume filling ratio of the heated aromatic generating base material aggregate 421 to the volume of the heated aromatic generating source 420 was 0.5 .9. The composition was the same as that of the heated aromatic generating base material in Example 6. ≪Example 8≫

[0110] In Example 8, the influence of the cross-sectional shape perpendicular to the longitudinal direction of the heat-generating aromatic substrate was compared with Example 7. For the purpose of confirming the influence of the cross-sectional shape perpendicular to the longitudinal direction of the heat-generating aromatic substrate, a sheet-shaped heat-generating aromatic substrate with a thickness of 0.1 mm, manufactured in exactly the same manner as in Example 3 for confirming the influence, was cut into a rectangle with a length of 150 mm and a width of 210 mm in the second forming step, and then cut into a shape with a length of 210 mm, a width of 1.0 mm, and a thickness of 0.1 mm using a rotary cutter, to produce a long prismatic heat-generating aromatic substrate. After aligning 142 of these heat-generating aromatic substrates in the longitudinal direction, they were wound and wrapped with paper having a basis weight of 34 g / m2 and glued, and a cylindrical roll with an outer diameter of 5.5 mm was produced. After being cut to a length of 42.0 m, a heat-generating aromatic source 420 was produced. As a result, 142 heat-generating aromatic substrate aggregates 421 with a length of 42.0 mm, a width of 1.0 mm, and a thickness of 0.1 mm were wound around a paper-made heat-generating aromatic substrate wrapping member 422. The heat-generating aromatic source 420 contained 0.64 g of the heat-generating aromatic substrate aggregate 421 per heat-generating aromatic source 420, and the volume filling ratio of the heat-generating aromatic substrate aggregate 421 to the volume of the heat-generating aromatic source 420 was 0.60. The composition was the same as that of the heat-generating aromatic substrate in Example 6. .60. The composition was the same as that of the heat-generating aromatic substrate in Example 6. <<Example 9>>

[0111] In Example 9, the influence of the cross-sectional shape perpendicular to the longitudinal direction of the heat-generating aromatic substrate was compared with Example 7. For the purpose of confirming the influence of the cross-sectional shape perpendicular to the longitudinal direction of the heat-generating aromatic substrate, a sheet-shaped heat-generating aromatic substrate with a thickness of 0.5 mm, manufactured in exactly the same manner as in Example 4 for confirming the influence, was cut into a rectangle with a length of 150 mm and a width of 210 mm in the second forming step, Using a rotary cutter, cut into a shape with a length of 210 mm, width of 2.0 mm, and thickness of 0.5 mm. Cutting was performed to produce long prismatic heated aroma generating substrates.

[0112] The heated aroma-generating substrate is made of 14 pieces aligned lengthwise and made of paper with a basis weight of 34 g / m2. The roll is then wrapped around the material and glued to create a cylindrical roll with an outer diameter of 5.5 mm. After the heating, the heated aroma source was cut to a length of 42.0 mm. 142 heated aroma-emitting substrates, each 42.0 mm long, 2.0 mm wide, and 0.5 mm thick The assembly 421 is wrapped around a heated aroma generating substrate wrapping member 422 made of paper. The source 420 is a heated aroma generating material collection of 0.63 g per heated aroma generating source 420. The volume of the heated aroma generating substrate assembly 420 including the combination 421 is The volume filling rate of 21 was 0.59. The composition was the same as that of the heated aroma-generating substrate of Example 6. It is a completion. <Comparative Example 4>

[0113] Since the composition is the same as that of Comparative Example 2, which confirms the effect of the second binder, the results shown in Comparative Example 2 were obtained. In order to confirm the effect of the heat source by performing a smoking test, Heated aroma sources of the same size as those in Example 7 and Comparative Example 3 were manufactured. Example 10

[0114] Example 10 also aims to confirm the influence of curing. Confirm that the aroma-generating sheet of 0.3 mm thick heated product was manufactured in exactly the same manner as in Example 5. In the second molding step, the substrate was cut in exactly the same manner as in Example 6, and then subjected to the same processing. A thermal aroma source was produced. The result was a tube measuring 42.0 mm in length, 1.5 mm in width, and 0.3 mm in thickness. Forty-two heated aroma generating substrate assemblies 421 made of paper were wound around a heated aroma generating substrate wrapping member 422 to form a heated aroma generating source 420. Each heated aroma generating substrate assembly 421 contained 0.64 g of the heated aroma generating substrate, and the volume filling ratio of the heated aroma generating substrate assemblies 421 to the volume of the heated aroma generating source 420 was 0.60. The composition was the same as that of the heated aroma generating substrate in Example 5. To specifically show the influence of the type and addition method of the binder, heated aroma generating sources of Examples 1 to 10 and Comparative Examples 1 to 4 were manufactured. Furthermore, when attempting to examine the combination order of different types of binders, in the first mixing similar to Example 1, when the first binder of a cellulose-based polysaccharide was replaced with a second binder which was a polysaccharide other than the cellulose-based polysaccharide, partially gelled lumps were generated and remained in the subsequent steps, so a uniform heated aroma generating substrate could not be manufactured. Therefore, the description as a comparative example was omitted. Using the heated aroma generating sources of Examples 1 to 10 and Comparative Examples 1 to 4, the following Evaluations 1 to 3 were carried out to specifically show the effects of the stepwise addition of the first binder and the second binder, as well as the effects and influence of curing. [Evaluation 1-1] To evaluate the heated aroma generating sources of Examples 1 to 5 and Comparative Examples 1 and 2, the Icos (registered trademark) 100, a heating smoking device equipped with a blade type heat source 130 by a heater manufactured by Philip Morris, shown in FIG. 1, was used. In this smoking device 100, the heat source 130 was...

[0115] As described above, to specifically show the influence of the type and addition method of the binder, heated aroma generating sources of Examples 1 to 10 and Comparative Examples 1 to 4 were manufactured. However, when further attempting to examine the combination order of different types of binders, in the first mixing similar to Example 1, when the first binder of a cellulose-based polysaccharide was replaced with a second binder which was a polysaccharide other than the cellulose-based polysaccharide, partially gelled lumps were generated and remained in the subsequent steps, so a uniform heated aroma generating substrate could not be manufactured. Therefore, the description as a comparative example was omitted. In the first mixing similar to Example 1, when the first binder of a cellulose-based polysaccharide was replaced with a second binder which was a polysaccharide other than the cellulose-based polysaccharide, partially gelled lumps were generated and remained in the subsequent steps, so a uniform heated aroma generating substrate could not be manufactured. Therefore, the description as a comparative example was omitted.

Therefore, the description as a comparative example was omitted. The description as a comparative example was omitted.

[0116] Using the heated aroma generating sources of Examples 1 to 10 and Comparative Examples 1 to 4, the effects of the stepwise addition of the first binder and the second binder, as well as the effects and influence of curing, could be specifically shown. Next, the following Evaluations 1 to 3 were carried out. Next, the following Evaluations 1 to 3 were carried out to specifically show the effects of the stepwise addition of the first binder and the second binder, as well as the effects and influence of curing. [Evaluation 1-1]

[0117] To evaluate the heated aroma generating sources of Examples 1 to 5 and Comparative Examples 1 and 2, the Icos (registered trademark) 100, a heating smoking device equipped with a blade type heat source 130 by a heater manufactured by Philip Morris, shown in FIG. 1, was used. This smoking device 100 had a heat source 130 that was... In this smoking device 100, the heat source 130 was... Blade type with a heater that is 4.5 mm wide, 12 mm long up to the tip, and 0.4 mm thick It is heat source 130 and is provided on the side opposite to the chamber of body 110 (not shown) and generates heat by the electric power supplied from a battery, reaching about 300 to 350 °C. The heated aromatic cartridge 300 is mounted along 120 on the inner surface with an inner diameter of 7.0 m in the chamber provided in body 110. After being mounted, it is controlled by the control system stem built into body 110, and one heated aromatic cartridge 300 can be smoked by 14 inhalations. When the heated aromatic cartridges 300 of this example and this comparative example are inserted, the length of the portion protruding outward from body 110 is about 20 mm. On the other hand, the heated aromatic cartridge 300 to be mounted on this smoking device, as shown in FIG. 1, has a heated aromatic generation source 320, a support member 331, and a filter member 333, which are wound with a heated aromatic cartridge exterior member 310 and reinforce the mouthpiece 33 0 with a mouthpiece reinforcing member 3301. More specifically, the heated aromatic generation sources 320 with a length of 12 mm and an outer diameter of 6.9 mm, the support members 331 which are hollow tubes with a length of 8 mm and an outer diameter of 6.9 mm and having a cylindrical through-hole with an inner diameter of 4 mm, and the filter members 333 made of cellulose acetate fibers formed into a cylindrical shape with a length of

[0118] 23 mm and an outer diameter of 6.9 mm manufactured in Examples 1 to 5 and Comparative Examples 1 and 2 are longitudinally attached in this order. These are coated with a predetermined amount of adhesive at a predetermined position on the inner surface, and are wound with a heated aromatic cartridge exterior member 310 which is paper with a basis weight of 38 g / m2 so as to have an outer diameter slightly less than 7.0 mm. Further, the filter of the mouthpiece 330 ​​​​​​​​​Paper with a basis weight of 40 g / m², with an adhesive applied to its inner surface, was wound and manufactured so as to overlap with the rotor member 333 portion. In this case, for the heated aromatic cartridge exterior member 310, the basis weight is paper of 32 g / m² to 45 g / m², or a plastic film having a strength equivalent to that of this paper is preferably used to maintain the minimum required strength. However, for the portion that is bitten by the lips, in order to prevent damage caused by the penetration of saliva, it is preferable to reinforce with paper having a basis weight of 40 g / m² or more. Since the heated aromatic cartridge exterior member 310 does not come into contact with the heat source 130, a plastic film corresponding to the strength of each paper can be used. Also, since the plastic film prevents the penetration of saliva and does not require the mouthpiece reinforcing member 3301, it is preferable. In particular, from the viewpoint of environmental protection, it is even more preferable to use a biodegradable plastic film. However, in the case of a plastic film, it is necessary to select a film thickness according to the material.

[0119] In the case of the blade-type heat source 240, a drop test of the heated aromatic generation base material 3211 (Fig. 3) was conducted to confirm the effects of the binder and curing. This is because, in the case of the blade-type heat source 130 as shown in Fig. 1, the heated aromatic generation base material assembly 321 comes into contact with the blade-type heat source 240 and is heated, so that the heated aromatic generation base material 3211 (Fig. 3) after smoking tends to shrink and fall easily, and the heated aromatic generation base material assembly 321 during smoking tends to contaminate the blade-type heat source 130 and the chamber inner wall 120. The evaluation was carried out on the heated aromatic cartridges 300 equipped with the heated aromatic generation sources 320 manufactured in Examples 1 to 5 as well as Comparative Examples 1 and 2, which were mounted on the heating smoking device 100 equipped with the blade-type heat source 130 and smoked. After this is done, the heated aroma cartridge 300 is removed, and the heated aroma generation source 320 is directed vertically downward, and the presence or absence of the fall of the heated aroma generation substrate 3211 (FIG. 3) is examined. This was carried out. This was done.

[0120] The criteria for this evaluation are as follows. Rank A: There is no fall of the heated aroma generation substrate, and there is little contamination of the blade-type heat source and the chamber inner wall. There is little Rank B: A part of the heated aroma generation substrate has fallen, and the contamination of the blade-type heat source and the chamber inner wall is conspicuous. Contamination is conspicuous. [Evaluation 1-2]

This was used. This smoking device 200 is provided with an omnidirectional heat source 240 by electromagnetic induction heating along the inner surface 220 of the chamber of the body 210.

[0122] On the other hand, as shown in FIG. 2, the heatable aroma cartridge 400 to be attached to this smoking device has a heatable aroma generating source 420, a cooling member 432, a filter member 433, and a mouthpiece 430 composed of a hollow tube 434, which is wound by a heatable aroma cartridge exterior member 410. More specifically, the heatable aroma generating sources 420 having a length of 42 mm and an outer diameter of 5.5 mm, a length of 25 mm and a thickness of 0.5 mm manufactured in Examples 6 to 10 and Comparative Examples 3 and 4, a cooling member 432 formed into a cylindrical shape with an outer diameter of 5.5 mm by winding a cardboard, a length of 8 mm and an outer diameter of 5. A filter member 433 made of cellulose acetate fibers formed into a cylindrical shape of 5 mm, and a hollow tube 434 formed into a cylindrical shape with an outer diameter of 5.5 mm by winding a cardboard with a length of 8 mm and a thickness of 0.5 mm are longitudinally attached in this order. A predetermined amount of adhesive is applied at a predetermined position on the inner surface. The heatable aroma cartridge exterior member 410, which is a paper with a basis weight of 38 g / m2, 20 mm long and 83 mm wide, is wound so that the outer diameter is slightly less than 5.6 mm. In the case of the omnidirectional heat source 240, the insertion test of the heatable aroma cartridge 400 was performed to confirm the effect of the binder and curing. This is because, as shown in FIG. 2, in the case of the cylindrical can-shaped omnidirectional heat source 24 0, since the long and narrow heatable aroma cartridge 400 is inserted into the long and narrow cylindrical can, it is difficult to attach the heatable aroma cartridge 400, and in some cases, it may lead to its damage. The evaluation was conducted by asking five subjects about the feeling of attaching the heatable aroma cartridge 400 to the heating type smoking device 400 when smoking. It was mounted so as to be slightly less than 5.6 mm in outer diameter.

[0123]

[0124] ​​​​​​​The criteria for this evaluation are as follows. Rank A: There is no problem in mounting the heated aromatic cartridge. Rank B: It is difficult to mount the heated aromatic cartridge and, in some cases, it may be damaged. [Evaluation 2-1]

[0125] In the smoking conducted in [Evaluation 1-1], a sensory evaluation was performed by 5 subjects, and the effects of the binder and preservation were confirmed. The sensory evaluation was conducted with a focus on the delicate aroma emitted by the tea. was carried out.

[0126] The criteria for this evaluation are as follows. Rank A: The level at which the aroma of the tea can be enjoyed during smoking. Rank B: The level at which the aroma of the tea is insufficient during smoking. [Evaluation 2-2]

[0127] Even in the case of the omnidirectional heat source 240, similar to the case of the blade-type heat source 130, in the state shown in Fig. 2, 5 subjects smoked and a sensory evaluation was performed to confirm the effects of the binder and preservation. Also in this case, a sensory evaluation focusing on the delicate aroma emitted by the tea was conducted.

[0128] The criteria for this evaluation are as follows. Rank A: The level at which the aroma of the tea can be enjoyed during smoking. Rank B: The level at which the aroma of the tea is insufficient during smoking. [Evaluation 3]

[0129] In Evaluations 1 and 2, the effects of the binder and preservation were confirmed by the drop test of the heated aroma-generating substrate, and also, the insertion test and smoking test of the heated aromatic cartridge. However, it was found that these effects are correlated with the mechanical strength of the sheet-like heated aroma-generating substrates produced in Examples 1 to 10 and Comparative Examples 1 to 4. were found.

[0130] Actually, the sheet-like heat-generating aromatic substrates of Examples 1, 2, 5, 6, 7, and 10, and Comparative Examples 1 to 4, which were manufactured to a thickness of 0.3 mm, were used, and test pieces cut to a width of 10.0 cm and a length of 22.0 cm were used to perform a general tensile strength test, and the measured breaking strength was evaluated. In the tensile strength test, the distance between the clamps sandwiching the test piece in the longitudinal direction was set to 20.0 cm, and the test was conducted in a test environment of 20 °C and 50% RH. The breaking strength was defined as the strength at the start of breakage when a crack or the like occurred in the test piece. As described above, the compositions of Examples 1 to 10 and Comparative Examples 1 to 4, as well as the shape and number of the heat-generating aromatic substrates used in Evaluations 1 to 3, are shown in Table 1-1, and the manufacturing conditions of the composition of the heat-generating aromatic substrate and the results of Evaluations 1 to 3 are shown in Table 1-2. By comparing Example 1 with Comparative Example 1 and Example 6 with Comparative Example 3, it was confirmed that it is preferable to add the first binder and the second binder step by step. Example 1 and Comparative Example 1 are heat-generating aromatic substrates manufactured under exactly the same conditions except that the first binder and the second binder are added in two steps in the former and added all at once in the latter. However, in the drop test and the smoking test using the heating smoking device 100 equipped with the blade-type heat source 130, better results were obtained for the former. Also, Example 6 and Comparative Example 3 are such that in Example 6 and Comparative Example 3, the first binder and the second binder are added in two steps in the former and added all at once in the latter, and they are heat-generating aromatic substrates manufactured under exactly the same conditions except for this. However, in the drop test and the smoking test using the heating smoking device 100 equipped with the blade-type heat source 130, better results were obtained for the former.

[0132] The method of adding the binder was confirmed to be preferably added step by step for the first binder and the second binder by comparing Example 1 with Comparative Example 1 and Example 6 with Comparative Example 3. Example 1 and Comparative Example 1 are heat-generating aromatic substrates manufactured under exactly the same conditions except that the first binder and the second binder are added in two steps in the former and added all at once in the latter. However, in the drop test and the smoking test using the heating smoking device 100 equipped with the blade-type heat source 130, better results were obtained for the former. Also, Example 6 and Comparative Example 3 are such that by comparing Example 6 with Comparative Example 3, it was confirmed that it is preferable to add the first binder and the second binder step by step. Example 6 and Comparative Example 3 are heat-generating aromatic substrates manufactured under exactly the same conditions except that the first binder and the second binder are added in two steps in the former and added all at once in the latter. However, in the drop test and the smoking test using the heating smoking device 100 equipped with the blade-type heat source 130, better results were obtained for the former. Example 1 and Comparative Example 1 are heat-generating aromatic substrates manufactured under exactly the same conditions except that the first binder and the second binder are added in two steps in the former and added all at once in the latter.

In the drop test and the smoking test using the heating smoking device 100 equipped with the blade-type heat source 130, better results were obtained for the former. Also, Example 6 and Comparative Example 3 are such that Example In the same relationship as that between 1 and Comparative Example 1, in the insertion test and smoking test using the heating type smoking device 200 equipped with the omnidirectional heat source 240 in the composition produced by the two-step addition of the binder a better result is obtained for the heated aroma generating base material produced therefrom.

[0133] Although the cause is not clear, the first binder of the cellulose-based polysaccharide promotes the uniform mixing and dispersion of the aroma source material and the aerosol former to form a stable sol state, and then the second binder, which is a polysaccharide other than the cellulose-based polysaccharide, forms a gel state that enhances these bindings Therefore, the dense dispersion enhances the volatilization action of the aromatic components of the tea by heating, and the binding force reduces the shrinkage action by heating and is considered to improve the mechanical strength of the heated aroma generating base material. This speculation is that when the first binder and the second binder are mixed by swapping, lumps partially gelled are generated in the mixture of the aroma source material, the aerosol former, and the binder, and a uniform dispersion state cannot be generated, which is supported by the phenomenon.

[0134] The effect of curing is obvious from the results of Evaluation 1-1, Evaluation 1 -2, Evaluation 2-1, and Evaluation 2-2 for Examples 1 and Examples 2 to 4, Examples 5 and Comparative Example 1 Examples 6 and Examples 7 to 9, and Examples 10 and Comparative Example 3, where the presence or absence of curing was compared. Curing can significantly improve the quality of the heated aroma generating base material, similar to the addition of the stepwise binder Also, as can be seen from comparing the evaluation results of Example 5 and Comparative Example 1, and Examples 10 and Comparative Example 3, when passing through the curing process it is not necessary to add the first binder and the second binder stepwise, and the effect of curing is considered to be quite large.

[0135] ​​​​Although the cause of this restorative effect is not clear, it is presumed that the first cellulose-based binder promotes the uniform mixing and dispersion of the aroma source material and the aerosol former, increasing and stabilizing the dispersion degree of the aroma source material in the sol state thus formed. This is supported by the fact that an increase in the volume of the mixture is observed during the curing process, which depends on the curing temperature and time. As a result, a denser dispersion structure of the aroma source material in the heated aroma-generating substrate produced through the curing process enhances the volatilization of the aromatic components of the tea by heating, reduces the shrinkage effect caused by heating the heated aroma-generating substrate, and is considered to improve its mechanical strength. The dispersion degree of the aroma source material in the sol state formed by promoting the uniform mixing and dispersion of the aroma source material and the aerosol former is increased and stabilized. An increase in the volume of the mixture is observed during the curing process, which is supported by the fact that it depends on the curing temperature and time. As a result, in the heated aroma-generating substrate produced through the curing process, a denser dispersion structure of the aroma source material enhances the volatilization of the aromatic components of the tea by heating, reduces the shrinkage effect caused by heating the heated aroma-generating substrate, and is considered to improve its mechanical strength. reduces the shrinkage effect caused by heating the heated aroma-generating substrate and improves its mechanical strength. is considered.

[0136] Also, from the evaluation results of Comparative Examples 2 and 4 without the addition of glucomannan, polysaccharides other than the cellulose-based polysaccharide used as the second binder are considered indispensable for improving the quality of the heated aroma-generating substrate, although the addition amount is small. However, a large amount of addition of such polysaccharides as the second binder tends to disrupt the dispersion system of the composition of the heated aroma-generating substrate and cause gelation. Therefore, it is necessary to use them in combination with the first binder and the cellulose-based polysaccharide used to enhance the dispersibility and improve the binding force of the heated aroma-generating substrate. Polysaccharides other than the cellulose-based polysaccharide used as the second binder are considered indispensable for improving the quality of the heated aroma-generating substrate, although the addition amount is small. However, a large amount of addition of such polysaccharides as the second binder tends to disrupt the dispersion system of the composition of the heated aroma-generating substrate and cause gelation. Therefore, it is necessary to use them in combination with the first binder and the cellulose-based polysaccharide used to enhance the dispersibility and improve the binding force of the heated aroma-generating substrate.

[0137] Furthermore, to support the causal relationships of such drop tests, insertion tests, and smoking tests, it was found that these evaluation results have a good correlation with the breaking strength of the sheet-like heated aroma-generating substrates produced in Examples 1 to 10 and Comparative Examples 1 to 4. The results are shown in the tensile test column of Table 1-2 for Examples 1, 2, 5, 6, 7, and 10, and Comparative Examples 1 and 2. it was found that these evaluation results have a good correlation with the breaking strength of the sheet-like heated aroma-generating substrates produced in Examples 1 to 10 and Comparative Examples 1 to 4. The results are shown in the tensile test column of Table 1-2 for Examples 1, 2, 5, 6, 7, and 10, and Comparative Examples 1 and 2. Examples 1, 2, 5, 6, 7, and 10, and Comparative Examples 1 and 2 shown in the tensile test column of Table 1-2 ​When comparing this evaluation 3 with the evaluation results 1-1, 1-2, 2-1, and 2-2, The breaking strength of the heated aroma-emitting sheet-shaped substrate produced by two-step addition of binder and curing The degree is high, and the cross-sectional area of ​​the test piece (0.3 × 100 mm 2 ) at least 5N or more, i.e. 0.167N / mm 2 The heated aroma cartridge has a breaking strength of the above. The mechanical strength required for the above, low heat shrinkage after smoking, and aroma due to heating during smoking are required. It is believed that this is an index for expressing the volatility of the components. The effects of stepwise addition of binder and curing are not inconsistent with, but rather correlate with, the effect of curing.

[0138] Secondly, the crosslinked PVP can sorb the cooling agent in a simple process, and the aroma generated by heating is reduced. A heated aroma source is provided that suppresses the dissipation of a freshening agent from a base material over time and contains the same. Even after storing the aroma cartridge for a long period of time, it will not be heated when you attach it to a heated smoking device and smoke it. In order to concretely demonstrate the effect of being able to fully enjoy the aroma of the aroma-generating material, Examples 11 to 18 and Comparative Examples 5 to 12 in which menthol and xylitol were used as the stimulants An experiment was conducted.

[0139] As a method for producing the aroma-generating substrate to be heated according to the present invention, as shown in FIG. 12, a first binder and A first mixing step in which the first binder is added while the second binder is added stepwise, and a second mixing step in which the first binder is added stepwise. It is best to provide a curing step between the first mixing step and the second mixing step in which the binder is added. In the following examples and comparative examples, the focus is on verifying the effect of crosslinked PVP, and the experiments are simplified. In order to achieve this, the first binder and the second binder are added at once, the curing step is omitted, and Only menthol was treated as a cooling agent. The manufacturing process shown in Fig. 11, which omits the curing process, was adopted, and a fourth mixing process shown in Fig. 12 was introduced. ≪Example 11≫

[0140] The fourth mixing process of mixing the lower alcohol in which the cooling agent was dissolved and crosslinked PVP was carried out as follows. 100 parts by mass of menthol 200 parts by mass of ethyl alcohol 200 parts by mass of crosslinked polyvinylpyrrolidone (PVP) These were weighed, menthol was dissolved in ethyl alcohol to produce a menthol / ethyl alcohol solution, and then crosslinked PVP was added to the menthol / ethyl alcohol solution and stirred and mixed to produce a menthol / ethyl alcohol / crosslinked PVP mixture in which the crosslinked PVP swelled.

[0141] On the other hand, since xylitol was to be added to the third mixing process, an aqueous xylitol solution having the following composition ratio was prepared. 100 parts by mass of xylitol 400 parts by mass of water

[0142] Also, as the aroma source material, tea leaves were used. After drying at 70°C so that the water content became about 2%, they were pulverized, and the material that passed through an 80-mesh sieve was used. It was put into a wet mixer in the third mixing process at the following composition ratio and treated for 15 minutes to produce a composition of the heated aroma-generating base material. 100 parts by mass of dried and pulverized tea leaves 25 parts by mass of menthol / ethyl alcohol / crosslinked PVP mixture 30 parts by mass of glycerin 30 parts by mass of propylene glycol 4 parts by mass of sodium carboxymethylcellulose (CMC) 15 parts by mass of methylcellulose 1 part by mass of glucomannan ​​​​​​​8 parts by mass of xylitol / aqueous solution

[0143] The composition produced in the third mixing step was put into a three-roll mill in the first forming step. By being pressed between the narrow rolls and shearing due to the roll speed difference, it was kneaded and dispersed uniformly, and a sheet-shaped heated aroma-generating base material with a predetermined thickness was produced. Incidentally, in the first forming step, since the composition becomes a high-viscosity paste, while observing the state of the sheet, pure water was appropriately added, and a doctor blade was pressed against the roll to form it into a sheet. In this forming step, moisture was appropriately evaporated, and the three-roll mill with the roll interval and the speed ratio between rolls adjusted was repeated 8 times so that it was formed into a sheet-shaped heated aroma-generating base material with a thickness of 0.3 mm. The sheet-shaped heated aroma-generating base material produced in the first forming step was put into the second forming step, and first, it was cut into a rectangle with a length of 150 mm and a width of 240 mm. Further, the sheet cut into this rectangle was cut into a length of 240 mm, a width of 1.5 mm, and a thickness of 0 .3 mm using a rotary cutter, and a long prismatic heated aroma-generating base material was produced. 50 long prismatic heated aroma-generating base materials produced in this way were aligned in the longitudinal direction, and then, using paper with a basis weight of 34 g / m2 as the heated aroma-generating base material wrapping member 322,

[0144] they were wound and pasted to produce a cylindrical roll with an outer diameter of 6.9 mm, and then it was cut into a length of 12.0 mm, and the heated aroma source 320 was produced. As a result, 50 aggregates of heated aroma-generating base materials with a length of 12.0 mm, a width of 1.5 mm, and a thickness of 0.3 mm were obtained.

[0145] After 50 long prismatic heated aroma-generating base materials produced in this way were aligned in the longitudinal direction, they were wound using paper with a basis weight of 34 g / m2 as the heated aroma-generating base material wrapping member 322 and pasted to produce a cylindrical roll with an outer diameter of 6.9 mm, and then it was cut into a length of 12.0 mm, and the heated aroma source 320 was produced. As a result, an aggregate of 50 heated aroma-generating base materials with a length of 12.0 mm, a width of 1.5 mm, and a thickness of 0.3 mm was obtained. 12.0 mm, width 1.5 mm, thickness 0.3 mm The heat-generating aroma source 321 is a heat-generating aroma source wound around the paper-made heat-generating aroma base material wrapping member 322 Each heat-generating aroma source 320 contains 0.29 g of the heat-generating aroma base material aggregate 3 21, and the volume filling rate of the heat-generating aroma base material aggregate 321 with respect to the volume of the heat-generating aroma source 320 was 0.60. Further, in the heat-generating aroma base material 3211 (Fig. 3), per 100 parts by mass of the aroma source material, 60 parts by mass of the aerosol former, 15 parts by mass and 4 parts by mass of methyl cellulose and CMC which are the first binders, respectively, and 1 part by mass of glucomannan which is the second binder 10 parts by mass of crosslinked PVP, 5 parts by mass of menthol, and 1.6 parts by mass of xylitol are contained.

[0146] In Examples 11 to 15 and Comparative Examples 5 to 8, the heat-generating aroma sources with such an outer diameter and length are processed because, in the smoking test described later, they are used as a heated smoking device with a bead-type heat source by a heater in an Icos (registered trademark, manufactured by Philip Morris). ≪Example 12≫

[0147] In exactly the same manner as in Example 11, a composition of the heat-generating aroma base material was produced. However, in order to confirm the influence of the shape of the heat-generating aroma base material, that is, the specific surface area, on the dissipation of menthol, in the first forming step, a three-roll mill in which the position of the doctor blade, the roll interval, and the roll speed ratio, etc. were adjusted differently from those in Example 11 was repeated 8 times to form a sheet-like heat-generating aroma base material thinner than 0.1 mm in thickness in Example 11.

[0148] The sheet-like heat-generating aroma base material produced in the first forming step was put into the second forming step ​​​​​​​​, First, it was cut into a rectangle with a length of 150 mm and a width of 240 mm. Further, the sheet cut into this rectangle was made narrower in width than in Example 11 using a rotary cutter and cut into a length of 240 mm, a width of 1.0 mm, and a thickness of 0.1 mm, and a long prismatic heated aromatic generating substrate was manufactured.

[0149] 225 long prismatic heated aromatic generating substrates manufactured in this way were aligned in the longitudinal direction, and then paper with a basis weight of 34 g / m2 was used as the heated aromatic generating substrate wrapping member 322 and wound and pasted, whereby a cylindrical roll with an outer diameter of 6.9 mm was manufactured. After that, it was cut into a length of 12.0 mm, and the heated aromatic generating source 320 was manufactured. As a result, 225 heated aromatic generating substrates with a length of 12.0 mm, a width of 1.0 mm, and a thickness of 0.1 mm were wound around the paper-made heated aromatic generating substrate wrapping member 322 to form the heated aromatic generating source 320. The heated aromatic generating substrate aggregate 321 contained 0.29 g of the heated aromatic generating substrate aggregate per heated aromatic generating source 320, and the volume filling ratio of the heated aromatic generating substrate aggregate 321 to the volume of the heated aromatic generating source 320 was 0.60. <<Example 13>>

[0150] In exactly the same manner as in Example 11, a composition of the heated aromatic generating substrate was manufactured. However, in order to confirm the influence of the shape of the heated aromatic generating substrate, that is, the specific surface area, on the dissipation of menthol, in the first forming step, the position of the doctor blade, the roll interval, and the roll speed ratio, etc. were adjusted differently from those in Example 11, and a three-roll mill was repeated 8 times to form a sheet-shaped heated aromatic generating substrate thicker than 0.5 mm in Example 11.

[0151] ​​​​​​​​​​The sheet-shaped heatable fragrance-generating base material produced in the first molding step was put into the second molding step , and first, it was cut into a rectangle with a length of 150 mm and a width of 240 mm. Further, the sheet cut into this rectangle was cut using a rotary cutter into a length of 240 mm, a width of 2.0 mm, and a thickness of 0.5 mm, which was wider than that in Example 11, to produce a long prismatic heatable fragrance-generating base material .

[0152] Twenty-three long prismatic heatable fragrance-generating base materials produced in this way were aligned in the longitudinal direction , and then, using paper with a basis weight of 34 g / m2 as the heatable fragrance-generating base material wrapping member 322 , they were wound and pasted to produce a cylindrical roll with an outer diameter of 6.9 mm. After that , it was cut into a length of 12.0 mm to produce the heatable fragrance source 320. As a result, a heatable fragrance source 320 in which 23 heatable fragrance-generating base material aggregates 321 with a length of 12.0 mm, a width of 2.0 mm, and a thickness of 0.5 mm were wound around a paper heatable fragrance-generating base material wrapping member 322 contained 0.29 g of the heatable fragrance-generating base material aggregate 3 21 per heatable fragrance source 320, and the volume filling ratio of the heatable fragrance-generating base material aggregate 321 to the volume of the heatable fragrance source 320 was 0.60 . <Comparative Example 5>

[0153] To clarify the influence of crosslinked PVP, the heatable fragrance-generating base material was produced without using crosslinked PVP

[0154] In the fourth mixing step, menthol was dissolved in ethyl alcohol at the following mixing ratio to produce a menthol / ethyl alcohol solution 100 parts by mass of menthol 400 parts by mass of ethyl alcohol

[0155] On the other hand, since xylitol is to be introduced into the third mixing step, an aqueous solution of xylitol with the following mixing ratio was prepared. An aqueous solution was prepared. 100 parts by mass of xylitol 400 parts by mass of water

[0156] Also, the aroma source material was treated in the same manner as in Example 11 and introduced into a wet mixer in the third mixing step at the following mixing ratio, and treated for 15 minutes to produce a composition of the heated aroma-generating base material. An aqueous solution was prepared. 100 parts by mass of dried and pulverized black tea leaves 25 parts by mass of menthol / ethyl alcohol solution 30 parts by mass of glycerin 30 parts by mass of propylene glycol 15 parts by mass of methyl cellulose 4 parts by mass of sodium carboxymethyl cellulose (CMC) 1 part by mass of glucomannan 8 parts by mass of xylitol / aqueous solution

[0157] The composition of the heated aroma-generating base material produced in the third mixing step, similar to Example 12, passed through the first molding step and the second molding step, and finally, 225 heated aroma-generating base material aggregates 321 with a length of 12.0 mm, a width of 1.0 mm, and a thickness of 0.1 mm were wound around a paper-made heated aroma-generating base material wrapping member 322 to produce a heated aroma source 320 with an outer diameter of 6.9 mm. And each of these heated aroma sources 320 contained 0.29 g of the heated aroma-generating base material aggregate 321, and the volume filling ratio of the heated aroma-generating base material aggregate 321 to the volume of the heated aroma source 320 was 0.60. Also, the heated aroma-generating base material 3211 (Fig. 3) did not contain crosslinked PVP, and for 100 parts by mass of the aroma source material, 60 parts by mass of aerosol foam, methyl cellulose and CMC which are the first binders were 15 parts by mass each. 1 of the forming step, the second forming step, and finally, 225 heated aroma generating base material aggregates 321 with a length of 12.0 mm, a width of 1.0 mm, and a thickness of 0.1 mm were wound around a paper-made heated aroma generating base material wrapping member 322 to produce a heated aroma source 320 with an outer diameter of 6.9 mm.

The mass part is 4 parts by mass, glucomannan as the second binder is 1 part by mass, menthol is 5 parts by mass, and xylitol is included in an amount of 1.6 parts by mass. and included. <Comparative Example 6>

[0158] Similar to Comparative Example 5, in order to clarify the influence of crosslinked PVP, uncrosslinked water-soluble PVP was used instead of crosslinked PVP, and a heated aroma generating source 320 was produced in exactly the same manner as in Example 12. As a result, 225 heated aroma generating base material aggregates 321 having a length of 12.0 mm, a width of 1.0 mm, and a thickness of 0.1 mm were wound around a paper-made heated aroma generating base material wrapping member 322 to produce a heated aroma generating source 320.

[0190] For the main purpose of determining the correlation between the precipitation test and the smoking test, using the heated aroma cartridges on which the precipitation test of Evaluation 4-1 was carried out, smoking was done by the method described in Evaluation 1-1, and, as described in Evaluation 2-1, a sensory investigation regarding the menthol cool feeling by 5 subjects was conducted. The smoking test was conducted as follows. Using the heated aroma generation sources manufactured in Examples 11 to 15 and Comparative Examples 5 to 8,

[0191] heated aroma cartridges 300 were manufactured in the same manner as in Evaluation 1-1. 20 of these heated aroma cartridges 300 were vertically packed in a paper box with a long side of 70 mm, a short side of 14 mm, and a height of 45 mm, with the heated aroma generation source 320 in contact with the bottom of the box. In this smoking test, the box packed with the heated aroma cartridges in this way was left under conditions similar to those under which a normal smoker stores them, at 25°C for 2 weeks. Then, using the heated aroma cartridges before and after being left, the subjects compared the menthol cool feeling. The evaluation criteria are as follows. Rank A: No change in the menthol cool feeling before and after being left Rank B: The menthol cool feeling after being left is slightly lower than before being left The evaluation criteria are as follows. Rank A: No change in the menthol cool feeling before and after storage Rank B: The menthol cool feeling after storage is slightly lower than before storage Rank C: The menthol coolness after storage is significantly lower than that before storage [Evaluation 5-2]

[0192] Regarding the smoking test, in addition to the same purpose as in Evaluation 5-1, the shape of the heat-generating aromatic substrate, the configuration of the heat-generating aromatic cartridge, and the heat source method of the heated smoking device and the accompanying shape of the heat-generating aromatic source are likely to be affected. Therefore, to confirm the presence or absence of these effects, using the heat-generating aromatic cartridge on which the deposition test of Evaluation 4-2 was performed, smoking was carried out by the method described in Evaluation 1-2, and a sensory evaluation of the menthol coolness by 5 subjects was conducted as described in Evaluation 2-2.

[0193] The smoking test was conducted as follows. Using the heat-generating aromatic sources produced in Examples 16 to 18 and Comparative Examples 9 to 12, in the same manner as in Evaluation 2-1, 400 heat-generating aromatic cartridges were manufactured. Twenty of these heat-generating aromatic cartridges were vertically packed in a paper box with a long side of 55 mm, a short side of 12 mm, and a height of 85 mm, with the heat-generating aromatic source 420 in contact with the bottom of the box. In this smoking test, the box packed with the heat-generating aromatic cartridges in this way was left under conditions similar to those under which an ordinary smoker stores it, at 25°C for 2 weeks. Then, using the heat-generating aromatic cartridges before and after storage, the subjects compared the menthol coolness. The evaluation criteria are as follows. Rank A: There is no change in the menthol coolness before and after storage Rank B: The menthol coolness after storage is slightly lower than that before storage Rank C: The menthol coolness after storage is significantly lower than that before storage [Evaluation 6]

[0194] The precipitation test and the smoking test are correlated to reveal the results of the smoking test. The factors that cause this are clarified, and smoking tests that require the manufacture of heated aroma cartridges are carried out. It is believed that it is possible to judge the results of smoking tests by precipitation tests without performing However, the deposition test was carried out to measure the amount of menthol deposited on the end surface of the heated aroma-emitting substrate of the heated aroma-emitting source. The number of white crystals in the bottle determines the temperature and does not depend on the internal condition of the heated aroma source. Therefore, in order to find a more accurate standard for judging the results of the smoking test, the menthol reduction rate was measured.

[0195] The menthol reduction rate was measured in an environment of 17°C and 65% relative humidity. The amount of menthol contained in the aroma-generating base material when the base material is precisely weighed out at about 5g to 10g. The mass of the aroma-generating substrate is taken as d(0), and the mass is calculated from the composition of the components constituting the aroma-generating substrate to be heated. The rate of decrease in the amount of the aroma generated by heating the precisely weighed substrate after it is left at 5°C for 24 hours is called the rate of decrease in the amount of the aroma generated by heating the substrate. The mass is d(24), and the mass after being left at 5°C for 48 hours is d(48), and the following formula is used: ) Here, the reason for subtracting d(48) from d(24) in the above formula is that When the precipitation test of the ole was observed in detail, the precipitation of white crystals was observed after 24 hours. Therefore, we excluded other dissipated components than menthol to better reflect the dissipation of menthol. It is significant that this can be done. d = {(d(24) - d(48)} / d(0) (1)

[0196] The compositions of Examples 11 to 18 and Comparative Examples 5 to 12 used in Evaluations 4 to 6 and The shape and number of the heated aroma-emitting substrates used in the heated aroma-emitting source are shown in Table 2-1. The manufacturing conditions of the composition of the heat-generating aromatic substrate and the results of Evaluations 4 to 6 are shown in Table 2-2.

Table 2-1

Table 2-2

[0197] As is clear from the results in Table 2-2, regardless of the cross-sectional shape perpendicular to the longitudinal direction of the heat-generating aromatic substrate, the length, and the number, which are the physical characteristics of the heat-generating aromatic substrate, and also regardless of the type of heat source of the heated smoking device, there is a good correlation between the deposition test, the smoking test, and the menthol reduction rate. In particular, when the menthol reduction rate is 0.200 or less, crosslinked PVP can adsorb menthol and effectively prevent the continuous dissipation of menthol. And such a heat-generating aromatic substrate can be manufactured only by applying a manufacturing method of a heat-generating aromatic substrate in which a step of mixing crosslinked PVP with a menthol / ethanol solution in which menthol is dissolved in ethanol is provided in order to mix menthol into the composition of the heat-generating aromatic substrate. Also, when the content of menthol is 1 to 10% by mass in the heat-generating aromatic substrate, the content of crosslinked PVP is 2 to 10% by mass in the heat-generating aromatic substrate, and is 1 to 6 times the content of menthol, in particular, the continuous dissipation of menthol can be prevented. The crosslinked PVP that can prevent such continuous dissipation of menthol is a cooling agent other than menthol, for example, menthol, and menthyl ether, menthyl ester,

[0198] menthyl carbonate and other menthol derivatives, and menthone and its derivatives, ​​​​and menthol and its derivatives, and menthane carboxylic acid-N-ethylamide [W S3], Nα-(menthane carbonyl) glycine ethyl ester [WS5], menthane car boxylic acid-N-(4-cyanophenyl) amide, menthane carboxylic acid-N-(4-cyano methylphenyl) amide, and menthane carboxylic acid-N-(alkoxyalkyl) ami d etc. menthane carboxylic acid amides, and methyldiisopropylpropionate amide 2,3-dimethyl-2-(2-propyl)-butyric acid-N-methylamide [WS23] etc. 2 ,3-dimethyl-2-(2-propyl)-butyric acid derivatives, and (l(-)-isopulego ol, l(-)-isopulegol acetate etc. isopulegol and its esters, N- (2-(pyridin-2-yl) ethyl)-3-p-menthane carboxamide, (1R, 2S,5R)-N-(4-methoxyphenyl)-5-methyl-2-(1-isopropyl) cyclohexane-carboxamide [WS12], and carboxamides such as oxamate , and are also effective for L-carboxylic, xylitol, thymol, spirantol, etc. has been confirmed.

[0199] Thirdly, by including microcrystalline cellulose in the heat-generating aromatic substrate, the aroma source material and the aerosol former are homogeneously mixed and dispersed via a binder, so that in the forming process of a sheet by repeating compression and shear , for example, by a three-roll mill etc., aggregation of the sheet breakage and adhesion to the metal roll can be effectively prevented, and in addition to reducing the time-dependent volume shrinkage due to drying etc. of the heat-generating aromatic substrate, it acts as a reinforcing material to improve the strength of the heat-generating aromatic substrate, so that the heat-generating aromatic substrate does not fall off, drop, and after smoking and after long-term storage , in order to specifically show that deformation and the like can be prevented, Experiments of Examples 19 to 26 and Comparative Examples 13 to 18 were conducted. The experiments of Comparative Examples 13 to 18 were carried out. ≪Example 19≫

[0200] Similar to Examples 11 to 13 and Examples 16 to 18, tea leaves were used as the aroma source material, aerosols olformers, CMC and glucomannan were used as binders, menthol and xylitol were used as cooling agents, and cross-linked PVP was used as the adsorbent for the cooling agent. In this example, however, microcrystalline cellulose was used instead of methyl cellulose, and its effect was confirmed. These were put into a mixer all at once in the following ratio and a composition of the heated aroma-generating base material was produced by stirring and kneading for 15 minutes. The composition was manufactured. 100 parts by mass of the dried and pulverized product of tea leaves 30 parts by mass of glycerin 30 parts by mass of propylene glycol 4 parts by mass of sodium carboxymethyl cellulose (CMC) 1 part by mass of glucomannan 15 parts by mass of microcrystalline cellulose 10 parts by mass of cross-linked polyvinylpyrrolidone (PVP) 5 parts by mass of menthol 1.5 parts by mass of xylitol

[0201] Note that the tea leaves were dried at 70°C so that the moisture content was about 2% by mass, pulverized, and those passing through an 80 mesh sieve were used. Also, microcrystalline cellulose having an average particle diameter of 90 μ m and a mass average molecular weight (Mw) of 36,000 was used. However, although the average particle diameter is 90 μm, the residue on a sieve with an opening of 75 μm is 5 2% by mass with respect to the total amount of microcrystalline cellulose, and the residue on a sieve with an opening of 250 μm is with respect to the total amount of microcrystalline cellulose with a narrow particle size distribution of 1% by mass, and the effect of microcrystalline cellulose is significantly manifested were selected.

[0202] The composition of the heated aroma - generating base material thus produced is compressed by being pushed into a narrow space between rolls and sheared by the roll speed difference, so that the high - viscosity paste can be uniformly kneaded and dispersed. Moreover, using a three - roll mill capable of forming a sheet, a sheet - shaped heated aroma - generating base material with a predetermined thickness was produced. In this example, using a pre - adjusted roll interval and roll speed ratio, the step of pressing a doctor blade against the roll to form a sheet was repeated 8 times, and a sheet - shaped heated aroma - generating base material with a thickness of 0.1 mm was produced. During this process, appropriate water supply was carried out according to the state of the sheet.

[0203] This sheet - shaped heated aroma - generating base material with a thickness of 0.1 mm was cut into a rectangle with a length of 150 mm and a width of 240 mm. After that, using a rotary cutter, a long prismatic heated aroma - generating base material with a length of 240 mm, a width of 1.5 mm, and a thickness of 0.1 mm was produced.

[0204] 150 long prismatic heated aroma - generating base materials thus produced were aligned in the longitudinal direction. Then, using paper with a basis weight of 34 g / m2 as the heated aroma - generating base material wrapping member 322, they were wound and pasted, and a cylindrical roll with an outer diameter of 6.9 mm was produced. After that, it was cut to a length of 12.0 mm, and a heated aroma - generating source was produced. As a result, 150 aggregates of heated aroma - generating base materials with a length of 12.0 mm, a width of 1.5 mm, and a thickness of 0.1 mm were wound around the paper - made heated aroma - generating base material wrapping member 322 to produce a heated aroma - generating source 3 21. 20 is a heated aroma generating substrate assembly 320 of 0.29 g per heated aroma generating source 320 1, and the volume of the heated aroma-emitting substrate assembly 321 relative to the volume of the heated aroma-emitting source 320 The volume packing ratio was 0.60. In addition, the aroma source was For 100 parts by mass of the material, 60 parts by mass of aerosol former, CMC and Glu as binders The alcomannan was 4 parts by mass and 1 part by mass, the microcrystalline cellulose was 15 parts by mass, and the crosslinked The bridged PVP was 10 parts by weight, and the menthol and xylitol were 5 parts by weight and 5 parts by weight, respectively. and 1.5 parts by mass. Example 20

[0205] In Example 20, the effect of microcrystalline cellulose was examined in a cross section perpendicular to the longitudinal direction of the heated aroma-generating substrate. In order to concretely demonstrate that the aroma generating effect does not depend on the surface shape, the aroma generating effect of the heated aroma generating substrate is compared with that of Example 19. The thickness of the heated aroma-generating substrate was increased. The composition was used to produce a sheet-shaped applied powder using a three-roll mill in which compression and shear were repeated. A thermal aroma generating substrate was prepared. In Example 20, the position of the doctor blade, the roll gap, In addition, the speed ratio between the rolls and the like were adjusted differently from those in Example 19. The process was repeated eight times to form a 0.3 mm thick sheet of the heated aroma-emitting substrate.

[0206] This sheet-shaped heated aroma-emitting substrate is 0.3 mm thick and has a length of 150 mm in height and 240 mm in width. After cutting into a square, a rotary cutter was used to cut the square into pieces 240 mm long, 1.5 mm wide, and 1.5 mm thick. Long prismatic heated aroma-emitting substrates with a length of 0.3 mm were prepared.

[0207] The 50 long rectangular pillar-shaped heated aroma-emitting substrates thus produced were aligned in the longitudinal direction. Then, a paper with a basis weight of 34 g / m2 was used as the heated aroma generating substrate wrapping member 322. After being rolled and glued, a cylindrical roll with an outer diameter of 6.9 mm is produced. , and cut into a length of 12.0 mm to produce a heated aroma source. 50 pieces of heated aroma-emitting substrates each having a diameter of 0.0 mm, width of 1.5 mm, and thickness of 0.3 mm. The heated aroma generating source 320 is wrapped around a heated aroma generating substrate wrapping member 322 made of paper. For each heated aroma generating source 320, 0.29 g of the heated aroma generating substrate aggregate 321 is used. The volumetric filling ratio of the heated aroma-emitting substrate assembly 321 to the volume of the heated aroma-emitting source 320 is also included. The filling rate was 0.60. The composition contained in the heated aroma-generating substrate 3211 (FIG. 3) is the same as in Example 19. Example 21

[0208] In Example 21, the effect of the microcrystalline cellulose was also observed in the cross section perpendicular to the longitudinal direction of the heated aroma-generating substrate. In order to concretely demonstrate that the aroma generating property is not dependent on the shape, the aroma generating property of the heated aroma generating substrate is further increased from that of Example 20. The thickness was increased. Therefore, the aroma-generating substrate to be heated was manufactured in exactly the same manner as in Example 29. The composition is used to produce a sheet-shaped heated product using a three-roll mill in which compression and shear are repeated. An aroma-generating substrate was produced. In Example 21, the position of the doctor blade, the distance between the rolls, The three-roll mill was designed with adjustments different from those in Example 20 with respect to the roll spacing, roll speed ratio, etc. The mixture was milled eight times to form a 0.5 mm thick sheet of the aroma-releasing substrate to be heated.

[0209] This sheet-shaped heated aroma-emitting substrate is 0.5 mm thick and has a length of 150 mm in height and 240 mm in width. After cutting into a square, a rotary cutter was used to cut the square into pieces 240 mm long, 1.5 mm wide, and 1.5 mm thick. A prismatic heated aromatic generating substrate 0.5 mm long was manufactured.

[0210] Thirty of the long prismatic heated aromatic generating substrates thus manufactured were aligned in the longitudinal direction and then, using paper with a basis weight of 34 g / m2 as the heated aromatic generating substrate wrapping member 322 they were wound and pasted to produce a cylindrical roll with an outer diameter of 6.9 mm. After that it was cut to a length of 12.0 mm to produce the heated aromatic source 320. As a result, a set of 30 heated aromatic generating substrates with a length of 12.0 mm, a width of 1.5 mm, and a thickness of 0.5 mm 321 was wound around the paper-made heated aromatic generating substrate wrapping member 322 to form the heated aromatic source 320, which contained 0.29 g of the heated aromatic generating substrate aggregate 3 21 per heated aromatic source 320, and the volume filling ratio of the heated aromatic generating substrate aggregate 321 to the volume of the heated aromatic source 320 was 0.60.

[0229] Using the heated aroma generating sources manufactured in Examples 19 to 26 and Comparative Examples 13 to 18, the following Evaluations 7 to 11, which can specifically demonstrate the effect of microcrystalline cellulose, were carried out. were carried out. were carried out. [Evaluation 7]

[0230] Using the heated aroma generating sources 320 of Examples 19 to 22 and Comparative Examples 13 to 16, the evaluation As described in FIGS. 1-1 and 1, a heated smoking article 100 equipped with a blade-type heat source was loaded with a heated flavor cartridge 300 for smoking. The heated flavor cartridge 300 was manufactured and after one smoking session, the heated flavor cartridge 300 was removed from the heated smoking article 100. A drop test of the heated flavor generating substrate 3211 ( FIG. 3) was conducted.

[0231] In the drop test, the heated flavor source 320 of the heated flavor cartridge 300 after smoking was vertically shaken up and down three times.

Twenty of these heated flavor cartridges 300 were vertically packed in a paper box with a length of 70 mm, a width of 14 mm, and a height of 45

[0233] mm, with the heated flavor source 320 in contact with the bottom of the box. After that, they were left at 45° C. for two weeks. Thereafter, the heated flavor cartridges 300 were taken out of the box, and the heated flavor source of the heated flavor cartridge 300 was vertically shaken up and down three times.

[0234] Using the heated aroma generating sources 420 of Examples 23 to 26 and Comparative Examples 17 and 18, as described in Evaluation 1-2 and FIG. 2, after manufacturing the heated aroma cartridge 400 mounted on the heating smoking device 200 equipped with an omnidirectional heat source and smoking, 20 of these heated aroma cartridges 400 were vertically packed in a paper box with a long side of 55 mm, a short side of 12 mm, and a height of 85 mm, with the heated aroma generating source 420 in contact with the bottom of the box, and then left at 45°C for 2 weeks. After being vertically packed in a paper box with a long side of 55 mm, a short side of 12 mm, and a height of 85 mm, with the heated aroma generating source 420 in contact with the bottom of the box, and then left at 45°C for 2 weeks. After being vertically packed in a paper box with a long side of 55 mm, a short side of 12 mm, and a height of 85 mm, with the heated aroma generating source 420 in contact with the bottom of the box, and then left at 45°C for 2 weeks.

[0235] After taking out the heated aroma cartridge 400 from the box thus left, as shown in FIG. 2, after smoking by mounting the heated aroma cartridge 400 on the heating smoking device 200, a series of operations of removing it were performed to evaluate the operability of the heated aroma cartridge 400 in a detachment test. The evaluation criteria are as follows.

[0236] Similar to Evaluation 9, the heated aroma cartridge 400 was packed in a box and left at 45°C for 2 weeks. After that, the heated aroma cartridge 400 was taken out of the box, and the heated aroma generating source 420 was vertically shaken up and down 3 times with the heated aroma generating source 420 facing downward to observe the presence or absence of detachment or dropping of the heated aroma generating base material wrapped by the paper-made heated aroma generating base material wrapping member 422 as the heated aroma generating source 420. The evaluation criteria are as follows. Observation was made. The evaluation criteria are as follows. Rank A: No detachment or dropping Rank B: With detachment or dropping [Evaluation 11-1]

[0237] The factors that result in the appearance of the results of Evaluations 7 to 10 are considered as follows. Aromatic source material and aerosol The ability to form a sheet by compression and shear for the foam to be mixed and dispersed through a binder, for example, in the production of a sheet of a heated aromatic generating substrate using a three-roll mill When microcrystalline cellulose is added in the production of a sheet of a heated aromatic generating substrate that can be formed into a sheet, aggregation breakage of the sheet and adhesion to the metal roll are effectively prevented and homogeneous mixing and dispersion are performed, so it is considered that a heated aromatic generating substrate with high density is produced . Also, since microcrystalline cellulose that does not absorb solvents such as water and ethanol exists in powder form in the heated aromatic generating substrate, it is considered that microcrystalline cellulose acts as a reinforcing material and a heated aromatic generating substrate with excellent strength is produced. Therefore, a heated aromatic generating substrate containing such microcrystalline cellulose is presumed to have reduced time-dependent volume shrinkage due to drying or the like . Therefore, the rate of change in the shape of the heated aromatic generating substrate due to volume shrinkage during heat drying of the heated aromatic generating substrate was measured to examine the correlation with Evaluations 7 to 10. The specific method for the rate of change due to volume shrinkage during heat drying is as follows. Prismatic test pieces for measuring the volume shrinkage of sheet-shaped heated aromatic generating substrates with a thickness of 0.3 mm produced in Examples 20 and 22, and Comparative Examples 14 and

[0238] 16 were cut into rectangular shapes with a length of 50 mm and a width of 15 mm. Heat drying was performed using a halogen moisture meter (electronic halogen moisture measuring instrument) (manufactured by Bangxi In strument Technology Co., Ltd., model number: DHS-50- 16. The volume shrinkage of the sheet-shaped heated aromatic generating substrates with a thickness of 0.3 mm produced in Examples 20 and 22, and Comparative Examples 14 and 16 was measured as test pieces of prismatic heated aromatic generating substrates cut into rectangular shapes with a length of 50 mm and a width of 15 mm. Heat drying was carried out using a halogen moisture meter (electronic halogen moisture measuring device) (manufactured by Bangxi In strument Technology Co., Ltd., model number: DHS-50- Using (5), the test piece was placed on the sample dish of the halogen moisture meter, and the test piece was heated from above the sample dish by the halogen lamp installed inside the cover. The heating temperature was set to 105 °C, and the length, width, and thickness of the test piece at drying times of 0 minutes, 10 minutes, and 15 minutes were measured. Using those measured values, from the definition formula of the change rate shown in Table 4-1, the length change rate La (%), width change rate Wa (%), width change rate Wa (%), and thickness change rate Ta (%) of the test piece with a length of 50 mm, width of 15 mm, and thickness of 0.3 mm after 10 minutes of drying, and the length change rate Lb (%), width change rate Wb (%), width change rate Wb (%), and thickness change rate Tb (%) of the test piece with a length of 50 mm, width of 15 mm, and thickness of 0.3 mm after 15 minutes of drying were calculated. Here, the length, width, and thickness of the test piece at a drying time of 0 minutes were the measured values when the moisture content was 15 to 20% by mass, adjusted by storing in an atmosphere at a temperature of 28 °C to 30 °C and a relative humidity of about 40% RH. [Evaluation 11-2]

[0239] Although it has the same purpose as Evaluation 11-1, the specific surface area differs depending on the shape of the test piece, and since it may affect the volume shrinkage, the shape dependence of the test piece regarding the correlation with volume shrinkage in Evaluations 7 to 10 was examined. That is, similar to Evaluation 1-1, in Examples 20 and 22, and also in Comparative Examples 14 and 16, the sheet-shaped heat-generating aromatic base material with a thickness of 0.3 mm manufactured was used, but a prismatic heat-generating aromatic base material cut into a rectangle with a length of 12 mm and a width of 1.5 mm was used as the test piece for measuring volume shrinkage.

[0240] The measurement method was carried out in exactly the same manner as in Evaluation 1-1, and from the definition formula of the change rate shown in Table 5-1, the length The length change rate La (%) of a test piece with a length of 12 mm, a width of 1.5 mm, and a thickness of 0.3 mm after 10 minutes of drying ), the width change rate Wa (%), the width change rate Wa (%), and the thickness change rate Ta (%), and The length change rate Lb ( %) of a test piece with a length of 50 mm, a width of 15 mm, and a thickness of 0.3 mm after 15 minutes of drying, the width change rate Wb (%), the width change rate Wb (%), and the thickness change rate Tb (%) were calculated . Here too, the length, width, and thickness of the test piece at 0 minutes of drying were adjusted by storing in an atmosphere at a temperature of 28°C to 30°C and a relative humidity of about 40% RH, and are the measured values when the moisture content is 15 ~20 mass%.

[0241] The compositions of Examples 19 to 26 and Comparative Examples 13 to 18 used in Evaluations 7 to 11 above, as well as the shape and number of the heated aroma generating substrates used as the heated aroma source are shown in Table 3-1, and the results of Evaluations 7 to 11 are shown in Table 3-2. Furthermore, the calculated values of the shape change rate due to volume shrinkage of the heated aroma generating substrate defined in Tables 4-1 and 5-1 are shown in Tables 4-2 and 5-2 . .

[0242] As is clear from the comparison between Examples 19 to 22 and Comparative Examples 14 ~16 and the comparison between Examples 23 to 26 and Comparative Examples 17 and 18 in the results of each drop test and desorption test shown in Table 3-2, regardless of the cross-sectional shape perpendicular to the longitudinal direction of the heated aroma generating substrate, a heated aroma source equipped with a heated aroma generating substrate containing microcrystalline cellulose was able to solve the problems of dropping and falling of the heated aroma generating substrate that are considered to be caused by volume shrinkage even when exposed to continuous drying and heat drying due to smoking. This problem is different between a blade-type heat source by a heater and an omnidirectional heat source by electromagnetic induction heating . ​, heating method, maximum temperature reached, and regardless of the structure of the heated aroma source and the heated aroma cartridge, etc., it was solved by adding microcrystalline cellulose. It was solved by the addition of microcrystalline cellulose regardless of the heating method, the maximum temperature reached, and the structure of the heated aroma source and the heated aroma cartridge, etc.

Table 3-1

Table 3-2

[0243] The effect of this microcrystalline cellulose can be seen from Table 4-2 showing the shape change rate in a test piece with a length of 50 mm, a width of 15 mm, and a thickness of 0.3 mm. The length change rate La = 7.2%, the width change rate Wa = 5.7%, and the thickness change rate Ta = 1.2% of the heated aroma generating substrate containing 2% by mass of microcrystalline cellulose after 10 minutes of drying, and the length change rate Lb = 8.1% after 15 minutes of drying , the width change rate Wb = 6.1%, and the thickness change rate Tb = 1.5%. At least any one of them can be used as a threshold value, and it is not necessary to satisfy all these threshold values simultaneously. And as shown in Table 3-2, if this shape change rate is satisfied, a good correlation can be obtained with the results of each drop test and desorption test. Thus, the reason that only one of the length, width, and thickness needs to be satisfied is not clearly recognized in Table 4-2, but when drying a heated aroma generating substrate with a smaller cross-sectional area perpendicular to the longitudinal direction, distortion occurs, and there is anisotropy in the heated aroma generating substrate in which plant stems and leaves, etc. are dispersed as the aroma source material. This is because of this.

[0244] ​This correlation is the shape change in a test piece with a length of 12 mm, a width of 1.5 mm, and a thickness of 0.3 mm In Table 5-2 showing the rate, a heated aromatic generating base material containing 2% by mass of microcrystalline cellulose After 10 minutes of drying, the length change rate La' = 4.8%, the width change rate Wa' = 5.0%, and the thickness Change rate Ta' = 1.2%, and for 15 minutes of drying, the length change rate Lb' = 5.8%, the width change rate Wb' = 5.1%, and the thickness change rate Tb' = 1.5%. Any one of these can be used as the threshold value, and it is not necessary to satisfy all of these thresholds simultaneously. Also in this case, as shown in Table 3-2 If this shape change rate is satisfied, a good correlation can be obtained with the results of each drop test and desorption test is obtained.

[0245] Thus, the heated aromatic generating base material of the present invention is composed of materials with different properties such as an aromatic source material, an aerosol former, and a binder. However, due to the type of additive and its addition method, as well as the manufacturing method such as curing of the composition, the addition and addition method of crosslinked PVP, and the addition of microcrystalline cellulose, it becomes possible to uniformly mix and disperse the aromatic source material, aerosol former, binder, etc., and while preventing easy dissipation of the aromatic agent over time, it also realizes prevention of shrinkage of the shape over time and prevention of shrinkage of the shape due to heating, and provides a high-quality heated aromatic generating base material that can achieve this. is. of.

[0246] As a result, when the heated aromatic cartridge provided with the heated aromatic source composed of the heated aromatic generating base material of the present invention is detached from the heat-not-burn smoking device, deformation of the heated aromatic generating source, heated aromatic generation when detaching the heated aromatic cartridge provided with the heated aromatic source composed of the heated aromatic generating base material of the present invention from the heat-not-burn smoking device, deformation of the heated aromatic generating source, heated aromatic generation Solve problems such as the peeling off and dropping of the base material, and impart the toughness and strength required for this molding process At the same time, a heated aroma-generating base material that can fully enjoy the aroma volatilized from the heated aroma source material can be provided.

[0247] In addition, when a cooling agent such as menthol or xylitol is added as an aromatic agent to the heated aroma-generating base material of the present invention, the dissipation of the aromatic agent and the cooling agent over time is suppressed, and the heated aroma-containing agent Even after storing the heated aroma cartridge equipped with the aroma source for a long time, when it is attached to a heated smoking device and smoked, the aroma of the heated aroma-generating base material can be fully enjoyed.

[0248] Furthermore, the heated aroma-generating base material of the present invention has little dimensional change due to drying, and after attaching the heated aroma cartridge equipped with the heated aroma source containing the same to a heated smoking device and smoking it, there is no peeling off or dropping of the heated aroma-generating base material from the heated aroma cartridge, and even after long-term storage there is no peeling off or dropping of the heated aroma-generating base material from the heated aroma cartridge, it has excellent handling properties, and a heated aroma-generating base material that can prevent contamination of the heat source of the heated smoking device can be provided.

[0249] The present invention further aims to provide a heated aroma source using such a heated aroma-generating base material and a heated aroma cartridge equipped with the heated aroma source Therefore, it will be specifically described below with reference to the drawings. However, the heated aroma source and the heated aroma cartridge of the present invention are not limited to these, and various modifications can be made without departing from the gist of the present invention and implemented, and it is limited only by the technical idea described in the claims

[0250] Figure 1 shows an example of the heated aromatic cartridge 300 used in the above-described embodiments and comparative examples, which is suitable for a blade-type heat source using a heater. The heated aromatic cartridge 300 according to an embodiment of the present invention is an assembly 321 of the heated aromatic generating base material 3211 (FIG. 3) of the present invention wound around a heated aromatic generating base material wrapping member 322, a heated aromatic generating source 320, a support member 331 attached to one end of the heated aromatic generating source 320 on the suction side in the longitudinal direction, a filter member 333 attached to one end of the support member 331 on the suction side in the longitudinal direction, and a mouthpiece 330 composed of the support member 331 and the filter member 333 is wound around the filter member 333 portion of the mouthpiece 330 with a mouthpiece reinforcing member 3301 in a state of being wound by a heated aromatic cartridge exterior member 310.

[0251] Figure 2 shows an example of the heated aromatic cartridge 400 used in the above-described embodiments and comparative examples, which is suitable for an omnidirectional heat source using electromagnetic induction heating. The heated aromatic cartridge 400 according to an embodiment of the present invention is an assembly 421 of the heated aromatic generating base material of the present invention wound around a heated aromatic generating base material wrapping member 422, a heated aromatic generating source 420, a cooling member 432 attached to one end of the heated aromatic generating source 420 on the suction side in the longitudinal direction, a filter member 433 attached to one end of the cooling member 432 on the suction side in the longitudinal direction, a hollow tube 434 attached to one end of the filter member 433 on the suction side in the longitudinal direction, and is wound by a heated aromatic cartridge exterior member 410.

[0252] However, the heated aromatic cartridge of the present invention is not limited to such a configuration. ​​​​​​​​​​​​​The product can be made in a variety of configurations to meet the smoker's preferences regarding flavor, smoke, inhalation amount, cost, etc. It is characterized by the fact that it is possible to

[0253] The various configurations are shown in FIG. 1 using the heated aroma cartridge 300 suitable for the blade-type heat source. However, the heated aroma cartridge of the present invention is not limited to these. The present invention is limited only by the technical ideas described in the claims.

[0254] First, the heated aroma generating source 320 constituting the heated aroma cartridge 300 of the present invention is shown in FIG. As shown in FIG. 1, the assembly 321 of the aroma-generating substrate 3211 (FIG. 3) is an aroma-generating device. The aroma emitting device is characterized in that it is wrapped around a base wrapping member 322. As is clear from the cross-sectional view perpendicular to the longitudinal direction of the source, the heated aroma-generating substrate assembly of the present invention 321 is a rectangular columnar aroma-generating substrate (single unit) 3211 to be heated, and this aroma-generating substrate 3 211 and the heated aroma-generating base material primary aggregate 3212 formed by irregular contact. The inside of the heated aroma-emitting substrate assembly 321 and the heated aroma-emitting substrate assembly 3 Between the primary aggregate 21 and the heated aroma-generating substrate wrapping member 322, a gas flow path 321 is provided within the primary aggregate. A, gas flow path between primary aggregates 321B, gas flow path between substrate and primary aggregate 321C, A heated aroma-generating substrate that is easy to form a gas flow path 321D between the combined / wrapping members. It is characterized by its cross-sectional shape of 3211 and its arrangement parallel to the longitudinal direction.

[0255] However, the cross-sectional shape of the heated aroma-generating substrate is preferably a rectangle as shown in FIG. In order to achieve both a good balance between the formation of a gas flow path and the shape of the gas flow path, a polygonal or star-shaped polygon is preferable. It is more preferable from the viewpoint of achievement. Furthermore, it is even more preferable that the heated fragrance generating substrate is hollow.

[0256] Also, it does not necessarily have to be prismatic, and it may be sheet-shaped. In this case, it is preferable for the formation of the gas flow path that it is irregularly folded parallel to the longitudinal direction of the heated fragrance generation source.

[0257] Furthermore, as will be described later, the heated fragrance generation source does not necessarily require a heated fragrance generating substrate wrapping member. For example, it may be directly wound around an outer packaging member corresponding to the outer packaging member 310 of the heated fragrance cartridge in FIG. 4. In this

[0258] case, it is preferable that the outer packaging member is made of a material having strength in constructing the heated fragrance cartridge. Also, the heated fragrance wrapping member does not necessarily have to be paper. Since it does not come into contact with the blade-type heat source and aerosol formability resistance of the heated fragrance generating substrate is required, a plastic film is more suitable than paper. In particular, from the viewpoint of environmental protection, it is preferable to use a biodegradable plastic film. Examples of plastics include plastics such as polyolefin, polyester, nylon, and engineering plastics. Examples of biodegradable plastics include poly(3- It is necessary to be formed into a shape that exhibits functions according to respective uses.

[0259] The heated aroma cartridge 300 of FIG. 1 according to an embodiment of the present invention includes a heated aroma generating source 3 20, a support member 3 31 that is attached to one end on the suction side in the longitudinal direction of the heated aroma generating source 320, and a filter member 33 3 that is attached to one end on the suction side in the longitudinal direction of the support member 331. In a state of being wound by the heated aroma cartridge exterior member 310, Furthermore, a filter -member 333 portion of the mouthpiece 330 composed of the support member 331 and the filter member 333 is wound by a mouthpiece reinforcing member 3301. However, the mouth piece reinforcing member 3301 is not necessarily required, and at least an exterior member corresponding to the heated aroma cartridge exterior member 310 is sufficient. That is, excluding the heated aroma generating source that is an essential component, as shown in FIG. 4, a support member 331 having a function of preventing the movement of the heated aroma generating source mainly to the suction side, a cooling member 332 having a function of promoting the generation of an aerosol that mainly cools the volatilized aerosol former to form smoke, a filter member 333 having a function of filtering components that become off-flavors from the volatile components and smoke generated from the heated aroma generating source, and a hollow tube 334 having a function of being mainly easy to hold in the mouth. It is sufficient to include at least one or more selected from these. And, as shown in FIG. 4, the mouthpiece 330 is composed of at least one or more selected from the support member 331, the cooling member 332, the filter member 333, and the hollow tube 334. However, when two or more of these are provided as the mouthpiece, there is a rule of arrangement in the longitudinal suction side from the heated aroma generating source, and the support part source, as long as it has at least one or more selected from the support member 331 having a function of preventing the movement of the heated aroma generating source mainly to the suction side, the cooling member 332 having a function of promoting the generation of an aerosol that mainly cools the volatilized aerosol former to form smoke, the filter member 333 having a function of filtering components that become off-flavors from the volatile components and smoke generated from the heated aroma generating source, and the hollow tube 334 having a function of being mainly easy to hold in the mouth. And, as shown in FIG. 4, the mouthpiece 330 is composed of at least one or more selected from the support member 331, the cooling member 332, the filter member 333, and the hollow tube 334. However, when two or more of these are provided as the mouthpiece, there is a rule of arrangement in the longitudinal suction side from the heated aroma generating source, and the support part 331, the cooling member 332, the filter member 333, and the hollow tube 334. However, when two or more of these are provided as the mouthpiece, there is a rule of arrangement in the longitudinal suction side from the heated aroma generating source, and the support part 331, the cooling member 332, the filter member 333, and the hollow tube 334. However, when two or more of these are provided as the mouthpiece, there is a rule of arrangement in the longitudinal suction side from the heated aroma generating source, and the support part 331, the cooling member 332, the filter member 333, and the hollow tube 334. However, when two or more of these are provided as the mouthpiece, there is a rule of arrangement in the longitudinal suction side from the heated aroma generating source, and the support part 331, the cooling member 332, the filter member 333, and the hollow tube 334. However, when two or more of these are provided as the mouthpiece, there is a rule of arrangement in the longitudinal suction side from the heated aroma generating source, and the support part 331, the cooling member 332, the filter member 333, and the hollow tube 334. However, when two or more of these are provided as the mouthpiece, there is a rule of arrangement in the longitudinal suction side from the heated aroma generating source, and the support part 331, the cooling member 332, the filter member 333, and the hollow tube 334. However, when two or more of these are provided as the mouthpiece, there is a rule of arrangement in the longitudinal suction side from the heated aroma generating source, and the support part 331, the cooling member 332, the filter member 333, and the hollow tube 334. However, when two or more of these are provided as the mouthpiece, there is a rule of arrangement in the longitudinal suction side from the heated aroma generating source, and the support part member 331, the cooling member 332, the filter member 333, and the hollow tube 334. However, when two or more of these are provided as the mouthpiece, there is a rule of arrangement in the longitudinal suction side from the heated aroma generating source, and the support part ​The positional relationship of the heating member 331, the cooling member 332, the filter member 333, and the hollow tube 334 is preferably observed. It is preferably being observed.

[0260] For example, as shown in FIG. 5, the heated aroma cartridge 300 according to an embodiment of the present invention is such that the heated aroma generating substrate assembly 321 is wound by the heated aroma generating substrate wrapping member 322 and the heated aroma source 320 having water resistance and pressure resistance capable of maintaining its shape even when bitten by the lips is fixed to one end of the heated aroma cartridge exterior member 310. It is one of the simple structured heated aroma cartridges consisting only of the heated aroma source 320 and the heated aroma cartridge exterior member 310. In this case, other than the heated aroma source 320 the portion of the heated aroma cartridge exterior member 310 serves as the mouthpiece 330 and becomes the hollow tube 334.

[0261] The simplest heated aroma cartridge is one without the heated aroma generating substrate wrapping member 322 of the heated aroma source 320 in FIG. 5, but the heated aroma source 320 wound by the heated aroma generating substrate wrapping member 322 is more preferable in terms of being easy to handle in manufacturing the heated aroma cartridge.

[0262] Also, for example, as shown in FIG. 6, the heated aroma cartridge 300 according to an embodiment of the present invention is such that the hollow tube 334 formed of a material having water resistance and pressure resistance capable of maintaining its shape even when bitten by the lips is attached to one end on the suction side in the longitudinal direction of the heated aroma source 320 in which the heated aroma generating substrate assembly 321 is wound by the heated aroma generating substrate wrapping member 322 and is wound around the heated aroma cartridge exterior member 310, and the hollow tube 3 ​ 34 serves as the mouthpiece 330.

[0263] Based on the heated aromatic cartridge 300 shown in this Figure 6, the heated aromatic cartridge of the present invention can be a heated aromatic cartridge with various configurations. That is, the hollow tube 334 can be replaced with at least one or more selected from the support member 331, cooling member 332, and filter member 3 33 shown in Figure 4. Also, leaving the hollow tube 3 34, at least one or more selected from the support member 331, cooling member 332, and filter member 3 33 shown in Figure 4 can be added.
