Description

The present invention relates to a heated fragrance generating base material provided in a heated fragrance cartridge suitable for a heated smoking device, a heated fragrance generating base material provided with the heated fragrance generating base material, and a heated fragrance generating group thereof. Regarding the method of manufacturing the material.

In particular, the aroma generating base material to be heated of the present invention is produced by at least a molding process in which an aroma source material, an aerosol former, and a binder are mixed and then a compressive shearing force is applied. , Aerosolformer, and a base material for generating aroma to be heated, characterized in that the binder is uniformly dispersed and bound. As a result, when the heated fragrance cartridge provided with the heated fragrance source composed of the heated fragrance generating base material of the present invention is attached to or detached from the heated smoking equipment, the heated fragrance generating base material is deformed or dropped. In addition, problems such as dropping do not occur, and in smoking, the fragrance volatilized from the heated fragrance source material can be fully tasted, and in the production of the heated fragrance generating base material, the fragrance source material, Stable production is possible because the aerosolformer and the binder are uniformly dispersed and bound, and have the toughness and strength required for molding.

Further, the base material for generating aroma to be heated of the present invention is characterized in that when a refreshing agent such as menthol or xylitol is added as an aromatic agent, the dissipation of the cooling agent over time is suppressed, and the present invention contains the same. Even after the heated fragrance cartridge equipped with the heated fragrance generating source is stored for a long period of time, the effect of being able to fully enjoy the fragrance of the heated fragrance generating base material when it is attached to a heated smoking device and smoked is achieved. Play.

Further, the heated fragrance generating base material of the present invention is characterized in that the dimensional change due to drying is small, and a heated fragrance cartridge provided with a heated fragrance generating source composed of the substrate is attached to a heated smoking device. Even after smoking, the heated fragrance generating base material does not fall off or fall from the heated fragrance cartridge, and even after long-term storage, the heated fragrance generating base material does not fall off or fall from the heated fragrance cartridge. It has excellent handleability and has the effect of preventing contamination of the heat source of heat-not-burn smoking equipment.

By the way, conventionally, the above-mentioned "heated fragrance generating base material" is often referred to as an "aerosol forming base material", but an aerosol source material or an fragrance agent is used together with an aerosol former that forms an aerosol by heating. In the present invention, it is referred to as a "heated aroma generating base material" because the scent component of the above is also volatilized and the smoke of the aerosol and the scent of the fragrance source material and the fragrance are enjoyed by smoking. Based on this, the "aerosol-forming body" filled with the aerosol-forming base material and the "electronic cigarette cartridge" provided with the aerosol-forming body are referred to as "heated fragrance source" and "heated fragrance cartridge", respectively. .. However, the name of the "heated fragrance cartridge" is not limited, and may be referred to as a "smoking cartridge" or an "electronic cigarette compatible cartridge".

Further, the source material of the aroma is not limited, and tobacco plants of the Solanaceae tobacco genus, plants of the same genus, and non-tobacco plants that do not contain tobacco components can be used. "Aroma" means "good scent", and when smoking, the scent that drifts from the material itself (fragrance), the scent that floats in the space when heated (aroma), the scent that drifts in the mouth when inhaled (flavor), etc. Being sensational, "smoking" generally means smoking cigarettes, cigars, etc., but here we simply "enjoy the smoke," "taste the aroma," and "smoke." It means "to enjoy the fragrance and fragrance." Therefore, the "smoke" here is not generated by combustion, but is "smoke-like" or "smoke-like" such as droplets dispersed in the air such as aerosol.

In recent years, smoking cessation of tobacco has tended to spread widely in spaces where people gather, such as workplaces and restaurants. On the other hand, a tobacco manufacturer has developed a method of smoking a heated aromatic cartridge that generates an aerosol by the heat transferred from an electronically controlled blade-type heat source when it is installed in the chamber of a heated smoking device (patented). Document 1). This heated fragrance cartridge contains an fragrance source material to be heated, which is formed by using an aerosol former, an fragrance source material containing a tobacco plant of the genus Tobacco of the family Tobacco, and a fragrance generating base material to be heated containing a binder and the like. It is provided, and when the substrate to be heated is heated, volatile substances are generated, the volatile substances of the aerosol former are cooled and become smoke, and the volatile substances of the fragrance source material become fragrance, similar to combustion-type tobacco. You can enjoy smoking. This heat-not-burn smoking reduces the inhalation of harmful components produced by the thermal decomposition and burning of conventional cigarettes, resulting in a drastic decrease in the smoking population of heat-not-burn tobacco, whereas smoking of heat-not-burn tobacco. The population is increasing rapidly. For this reason, technological developments for more enjoyment of heat-not-burn smoking are being actively carried out (for example, Patent Documents 1 to 12).

The mechanism of such heated smoking differs depending on the form of the heated smoking device, the heated fragrance cartridge, and the like, and typical examples thereof are shown below. A heated fragrance cartridge having a heated fragrance generating source filled with a heated fragrance generating base material at one end and a mouthpiece at the other end contacts the heated fragrance generating source with the heat source of a heated smoking device. When it is attached and heated, volatile substances of the aerosol former and the aroma source material are released from the aroma generation source to be heated. This volatile matter is sucked into the mouthpiece side at the other end together with air by the smoker's suction. In this volatile transport process, the aerosol former volatiles cool and condense to form a smoky aerosol, while other volatiles fragrance the smoker's mouth and nose, resulting in this. You can enjoy smoking. Therefore, in the case of heat-not-burn smoking, the temperature is about 200 to 350 ° C., which can volatilize the aerosol former such as glycerin and propylene glycol contained in the aroma generating base material to be heated, that is, the degree to which the thermal decomposition of tobacco leaves starts. Since smoking can be performed at a temperature, 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.

As can be seen from this mechanism, in heat-not-burn smoking equipment, the heat source and its control method, which have a great influence on the generation of smoke and aroma, play an extremely important role, and as a result of long-term development, the heater is used. Blade-type heat sources have been widely used to date (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. Since the heating rate is high and the contact area with the aroma generating substrate to be heated is large, it is considered that the aim is to increase the production of volatile substances and provide a deep taste (Non-Patent Document 1).

On the other hand, various efforts have been similarly made for technological development regarding a base material for generating aroma to be heated, which is a source for generating smoke and aroma (for example, Patent Documents 6 to 12). An aerosol former having a boiling point of 180 to 300 ° C. such as glycerin and propylene glycol, which are the sources of smoke, is an essential component, and is mixed with tobacco plants, non-tobacco plants, and fragrances, which are fragrance source materials that are fragrance sources. Therefore, it is necessary to form a homogeneous viscoelastic body. Therefore, linear, side-chain, and branched polysaccharide polymers such as cellulose, guar gum, and gum arabic are used as binders. Further, it is necessary to add a wetting agent or the like for uniformly dispersing them.

However, conventionally, as a base material for generating aroma to be heated, an aqueous slurry in which an aerosol former, an aromatic source material, a binder, a wetting agent, etc. are dispersed in water is produced, and a papermaking process is performed through a papermaking process and then a compression / heating / drying process. A method of casting and molding by adding an appropriate amount of lower alcohol or water to a mixture of an aerosol former, an aromatic source material, a binder, a wetting agent and the like has been adopted (Patent Document 6 and Patent Document 6 and). 7). However, with these methods, it is not possible to produce a viscoelastic body in which the components constituting the heated aroma generating base material are homogenized, and the mechanical strength of the molded product is insufficient, so that the heated aroma is generated. In many cases, the problem of destruction occurs at the stage of processing the base material into a source of aroma to be heated. Further, since the non-homogenized base material for generating aroma to be heated has an insufficient packing state of the aroma source and the binder, it shrinks violently when heated and dried, and is in the stage of being processed into a aroma generating source to be heated. There is a problem that it is destroyed by heating and drying, and that the aroma-generating base material to be heated falls off or falls after smoking.

The effectiveness of the inorganic binder is disclosed with respect to the falling or falling, cracking or breakage of the heated aroma generating base material after smoking (Patent Document 8). This solution is based on the fact that the inorganic binder does not improve the inhomogeneity but improves the heat resistance to the heat source to suppress the combustion of the aroma generator to be heated, and moreover. Since the relative ratio of the aroma source material and the aerosol former to the base material for generating aroma to be heated decreases, there is a problem that the amount of aroma and smoke produced decreases.

In addition, the inhomogeneity derived from the chemical properties of the components constituting the aroma generating substrate to be heated also causes a decrease in the amount of aroma and smoke produced. In particular, the chemical affinity between the fragrance source material and the aerosol former is low, and the fragrance source material is not dissolved in the aerosol former and must be dispersed. Therefore, various volumes of aerosol former and fragrances of various sizes are required. The mass of the source material will be present irregularly. Therefore, even in the case of a base material for generating aroma to be heated in such an inhomogeneous state, even if it is heated by a heat source, uniform heat transfer to the aroma source material and the aerosol former is not performed, so that the aroma source does not occur. The aromatic components of the wood are not sufficiently volatilized, resulting in an inadequate taste in smoking, and the aerosol former is also not sufficiently volatilized, enough smoke to entertain the smoker's eyes. Cannot be generated. To solve such a problem, a solution has been proposed in which the addition of wax increases the fluidity of the volatile components of the aromatic source material and the aerosol former, and promotes the emission of the volatile matter from the aroma generating substrate to be heated. (Patent Documents 9 and 10). However, since the wax is hydrophobic, it is difficult to produce a homogenized base material for generating aroma to be heated, especially by the production method by the casting method, and a large improvement effect cannot be expected. In addition, there is a problem of mechanical strength that the base material for generating aroma to be heated becomes brittle due to wax.

Further, in the heat-not-burn tobacco as well, in order to obtain a refreshing feeling when smoking, a cooling agent such as menthol or xylitol may be added as an fragrance. In addition, flavors may be added to add flavors such as fruits and nuts. Even in such a case, in the heating and drying step of producing the aroma generating base material to be heated by the above-mentioned casting method, there is a problem that the cooling agent and the flavoring agent are dissipated, and the cooling agent and the flavoring agent are included and heated. The problem is that the cooling agent and flavoring agents dissipate over time because the components that make up the aroma-generating base material have a hydrophilic-hydrophobic balance and a large amount of components that are insoluble in the aerosol former are not homogenized. There is. With respect to these problems, inclusion of refreshing agents and flavors with various cyclodextrins and encapsulation of refreshing agents and flavors with wax are disclosed as means for solving these problems (Patent Document 11 and). 12). In order to form the former clathrate compound, a combination of an appropriate refreshing agent and flavoring agent and cyclodextrin is found, and after selecting an appropriate solvent, the cooling agent and flavoring agent and cyclodextrin are used. Is homogenized with a homogenizer and then spray-dried, freeze-dried, or vacuum-dried, which limits the applicable refreshing agents and flavors and requires a great deal of labor in production.

As described above, there is a problem of inhomogeneization in the aroma generating base material to be heated based on the manufacturing methods of cast molding and extrusion molding and the chemical properties of the constituent components. This problem may be solved by adopting a compression / shearing method as a manufacturing method. For example, a method of using a three-roll mill that can uniformly knead and disperse a high-viscosity paste by compression by being pushed between narrow rolls and shearing due to a difference in roll speed and that can be formed into a sheet is conceivable. Be done. However, in this case, it is difficult to form the sheet because the sheet, which is the base material for generating aroma to be heated, has insufficient strength and high adhesiveness, which causes cohesive failure and adhesion to the metal roll. Problems arise.

In this way, in order to smoke heat-not-burn tobacco, that is, to enjoy smoking by attaching the heated fragrance cartridge to the heated smoking equipment, along with the improvement of the heated smoking equipment, the heated fragrance source of the heated fragrance cartridge is used. It is necessary to further solve various problems caused by the composition of the base material for generating aroma to be heated.

The present invention is a heated fragrance generating base material provided in a heated fragrance cartridge suitable for heat-not-burn smoking equipment, and contains at least an fragrance source material, an aerosol former, and a binder, and after mixing these, Provided is a base material for generating aroma to be heated, which is produced through a molding process in which a compressive shearing force is applied, and is characterized in that an aromatic source material, an aerosol former, and a binder are uniformly dispersed and bound. The purpose is to do.

As a result, when the heated fragrance cartridge provided with the heated fragrance source composed of the heated fragrance generating base material of the present invention is attached to or detached from the heated smoking equipment, the heated fragrance generating source is deformed and the heated fragrance is generated. A heat-heated aroma-generating base material that solves problems such as falling and dropping of the base material, imparts the toughness and strength required for this molding process, and can fully enjoy the aroma volatilized from the heated aroma source material. Can be provided.

Further, in the base material for generating a fragrance to be heated of the present invention, when a refreshing agent such as menthol or xylitol is added as a fragrance, the dissipation of the fragrance or the cooling agent over time is suppressed, and the fragrance to be heated containing the fragrance is suppressed. Even after the heated fragrance cartridge equipped with the source is stored for a long period of time, the heated fragrance generating group can fully enjoy the fragrance of the heated fragrance generating base material when it is attached to a heated smoking device and smoked. The purpose is to provide materials.

Further, the heated fragrance generating base material of the present invention has little dimensional change due to drying, and even after a heated fragrance cartridge provided with a heated fragrance generating source containing the same is attached to a heated smoking device and smoked. The heated fragrance generating base material does not fall off or fall from the heated fragrance cartridge, and even after long-term storage, the heated fragrance generating base material does not fall off or fall from the heated fragrance cartridge, and has excellent handleability. It is an object of the present invention to provide a base material for generating aroma to be heated, which can prevent contamination of a heat source of a heated smoking device.

As described above, the main problem to be solved by the present invention is the homogeneous mixing of materials having different properties such as an fragrance source material, an aerosol former, a binder, and an fragrance agent, which are possessed by the conventional heated fragrance generating base material. And dispersal, as well as easy aging prevention of fragrance dissipation, and aging and thermal shape shrinkage prevention.

As a result of various studies on various materials in addition to the fragrance source material, aerosol former, binder, fragrance, etc. that constitute the substrate for generating fragrance to be heated, the inventor has selected two types of binders and theirs. It has been found that the above problems can be solved by an appropriate compounding method and the addition of crosslinked polyvinylpyrrolidone (PVP) and microcrystalline cellulose, and the present invention has been completed.

That is, the present invention is a base material for generating aroma to be heated, which contains at least an fragrance source material, an aerosol former, and a binder, and contains a first binder and a second binder as the binder, and is the first. At least one binder is selected from the group consisting of methyl cellulose, ethyl cellulose, carboxymethyl cellulose, carboxyethyl cellulose, hydroxymethyl cellulose, hydroxyethyl cellulose, and hydroxypropyl cellulose, and sodium salts, potassium salts, and calcium salts thereof. A type of cellulosic polysaccharide in which the second binder is a polyother than at least one cellulosic polysaccharide selected from the group consisting of glucomannan, guar gum, pectin, carrageenan, locust bean gum, and agar. It is a substrate for generating aroma to be heated, which is characterized by being a saccharide.

By using such a first binder and a second binder in combination, the fragrance source material and the aerosol former constituting the heated fragrance generating base material are uniformly mixed and dispersed, and the cohesive strength of both is increased. It becomes a base material for generating an aerosol to be heated, which is enhanced and has the toughness and strength required for molding. As a result, the heated fragrance generating base material falls off, falls, and is deformed immediately after manufacturing the heated fragrance generating base material provided with the heated fragrance generating base material and after storing it for a long period of time. It can be attached to and detached from the heated smoking equipment without any need. In addition, aroma from the aroma source material in smoking and smoking by the aerosol former are sufficiently generated. Further, since the aromatic source material and the aerosol former are uniformly mixed and dispersed via the binder, coagulation fracture occurs even when a molding process using a compressive shearing force, for example, three rolls is used. It becomes possible to mold the sheet-shaped aromatic substrate to be heated without any problem. Then, it was confirmed ^{that the breaking strength in the tensile strength test was 0.167 N / mm 2} or more in order to be a base material for generating aroma to be heated in order to exert such an effect.

In order to stably exhibit the above effect by the combined use of the first binder and the second binder, the first mixing step and the first mixing step of mixing the aromatic source material, the aerosol former, and the first binder. A second mixing step of mixing a second binder with the mixture produced in the first mixing step, or a first mixing step and a first mixing step of mixing an aromatic source material, an aerosol former, and a first binder. It is preferable that the manufacturing step is to mix a stepwise binder including a mixing molding step of molding the mixture produced in the mixing step 1 into a substrate to be heated while mixing the second binder. Although the cause of this is not clear, the first binder of the cellulosic polysaccharide promotes uniform mixing and dispersion of the aromatic source material and the aerosol former to form a stable sol state, and then the cellulosic polysaccharide. It is considered that the second binder, which is a polysaccharide other than the above, forms a gel state that enhances these bindings.

To support this speculation, swapping and mixing the first and second binders produced a partially gelled mass in the mixture of aromatic source, aerosolformer and binder. A phenomenon was observed in which a uniform dispersed state could not be generated.

Further, it is more preferable to add a curing step for curing the mixture produced in the first mixing step immediately after the first mixing step, and the temperature of the curing step is 15 ° C. or higher and 30 ° C. or lower, and the curing step is performed. When the step time is 72 hours or more and 336 hours or less, the combined effect of the first binder and the second binder is particularly maximized. In this curing step, the first binder of the cellulosic polysaccharide promotes uniform mixing and dispersion of the aromatic source material and the aerosol former to enhance and stabilize the dispersion degree of the aromatic source material in the sol state formed. It is presumed that it has the effect of making it. This is because an increase in the volume of the mixture is observed in the curing process. If the temperature is lower than 15 ° C, the volume increase is slight, and the effect of the curing step on the quality of the aroma-generating substrate to be heated is not recognized. If the temperature exceeds 30 ° C, the cause is unknown, but the mixture is gelled. Will be recognized. Further, if it is less than 72 hours, the volume increase is slight, and the effect of the curing step on the quality of the aroma generating substrate to be heated is not recognized. If it exceeds 336 hours, this volume increase is stopped and the curing step is subjected to. The effect on the quality of the heated aroma generating substrate is saturated, and further long-term curing may result in gelation.

When going through such a curing step, it is not necessary to add the first binder and the second binder step by step, and the aromatic source material, the aerosol former, the first binder, and the second binder A third mixing step for mixing the above can be provided, and a curing step for curing the mixture produced in the third mixing step can be provided as a manufacturing step. In this curing step, it is considered that the effect of increasing the dispersity of the aroma source material by the first binder and the effect of increasing the binding by the second binder occur in parallel.

The binder is preferably a combination of the above-mentioned cellulosic polysaccharide and other polysaccharides, but it is also preferable to further add cellulosic fibers extracted from a plant containing a large amount of cellulosic fibers. In particular, hemps such as linen, jute, nalta jute (Moroheiya), kenaf, hemp, Manila asa, and sisal, which have fiber diameters of 10 to 50 μm, as well as rice, oats, barley, wheat, crow wheat, honeybee, and limegi. The cellulose fibers of gramineous plants such as sugar cane, esparto, and bamboo uniformly mix, disperse, and bind the materials that make up the aroma-generating base material to be heated, and impart the toughness and strength required for molding. In addition, it is highly effective in preventing deformation, falling off, and falling.
In particular, rice, wheat, and sugar cane are even more preferable because they volatilize the aroma when heated.

Materials that are preferably used as an aroma source material are substances that emit aroma from themselves and substances that emit aroma when heated, and plants and processed products obtained by drying or fermenting them are preferable. Aroma source materials are roughly classified into tobacco belonging to the genus Solanaceae, above-ground foliage of plants of the same genus, and its components, as well as flowers, roots, underground stems, stems, seeds, fruits, and above-ground foliage of angiosperms. , And teas, angiosperms, sprouted vegetables, and fermented grains and beans are preferably used. It is more preferable to mix two or more kinds of aroma source materials, a material with a fragrance defined as an aroma drifting from the aroma source material itself, and a material with an aroma defined as an aroma drifting in a space by heating the aroma source material. , And, it is more preferable to mix three or more kinds of materials having a flavor defined as aroma floating in the mouth by heating the aroma source material. Specific examples of these are listed below.

In particular, propylene glycol, glycerin, and a mixture of propylene glycol and glycerin are preferable.

It is preferable to add a cooling agent and a crosslinked PVP to the aroma generating base material to be heated containing at least such an aroma source material, an aerosol former, and a binder. This is because the flavor in the mouth due to the volatile components of the refreshing agent results in refreshing smoking. The crosslinked PVP has a function of accommodating the cooling agent, and can prevent the cooling agent from being dissipated over time. Moreover, only by providing a step of mixing the refreshing agent dissolved in the lower alcohol with the crosslinked PVP, the refreshing agent is bound to the crosslinked PVP, so that the step of binding to cyclodextrin is unnecessary.

Examples of the refreshing agent include menthol, menthol derivatives such as mentyl ether, mentyl ester, and mentyl carbonate, menthon and its derivatives, mentane and its derivatives, and menthanecarboxylic acid-N-ethylamide [WS3]. ], Nα- (menthancarbonyl) glycine ethyl ester [WS5], mentancarboxylic acid-N- (4-cyanophenyl) amide, mentancarboxylic acid-N- (4-cyanomethylphenyl) amide, and mentancarboxylic acid- Mentancarboxylic acid amides such as N- (alkoxyalkyl) amide, and 2,3- of methyldiisopropylpropionic acid amides [2,3-dimethyl-2- (2-propyl) -butyric acid-N-methylamide [WS23]] Dimethyl-2- (2-propyl) -butyric acid derivatives and isopregols such as (l (-)-isopregol, l (-)-isopregol acetate and esters thereof, N- (2- (pyridine-2-yl) ) Ethyl) -3-p-mentanethanecarboxyamide, (1R, 2S, 5R) -N- (4-methoxyphenyl) -5-methyl-2- (1-isopropyl) cyclohexane-carboxamide [WS12], and oxamate Carboxamides such as, and L-carboxylic acid, xylitol, timol, spirantol, etc. can be used. Generate.

Further, it is preferable that the base material for generating aroma to be heated contains microcrystalline cellulose. Microcrystalline cellulose is a high-purity microcrystalline cellulose obtained by hydrolyzing and purifying pulp with an acid. It is a fluid powder that does not dissolve solvents such as water and ethanol, and is an excipient for tablet molding of pharmaceuticals. It is used as. This is because the fluidity of the microcrystalline cellulose and the high compressibility with a large volume change are effective in preventing cohesive failure and adhesion to the mold in the molding of tablets by the direct striking method. Also in the present invention, by adding microcrystalline cellulose, the aromatic source material and the aerosol former can be molded into a sheet by compression and shearing because they are uniformly mixed and dispersed via a binder, for example, 3 In the production of a sheet of a base material for generating an aerosol to be heated by this roll mill, it is possible to effectively prevent the sheet from coagulating and breaking and adhering to a metal roll.

In addition, since it does not absorb solvents such as water and ethanol, it exists in powder form in the aroma-generating base material to be heated, so that the volume shrinkage over time due to drying of the aroma-generating base material to be heated can be reduced. Can be done. In addition, it can act as a reinforcing material and improve the strength of the aroma generating substrate to be heated. Therefore, it is possible to prevent the base material for generating a fragrance to be heated from falling off, falling, and being deformed before and after smoking and after long-term storage.

The base material for generating aroma to be heated must contain at least an aroma source material, an aerosol former, and a binder, but these are uniformly mixed and dispersed, and the cohesive strength is enhanced, which makes it suitable for molding. In order to obtain a high-quality heat-treated aerosol-generating base material having the required toughness and strength, there was a specific compounding amount, and it was experimentally determined from a large number of compounding amounts. That is, the aroma source material and the aerosol former must be contained in an amount of 30 to 90% by mass and 10 to 40% by mass, respectively, in the base material for generating aroma to be heated, and the binders are the first binder and the first binder, respectively. It was clarified that the binders of 2 need to be contained in an amount of 1 to 30 parts by mass and 0.1 to 5 parts by mass with respect to 100 parts by mass of the aromatic source material, respectively. It was also found that the quality of the binder can be further improved by containing 1 to 25 parts by mass of the cellulose fiber with respect to 100 parts by mass of the aromatic source material.

By appropriately blending an appropriate amount of a cooling agent and crosslinked PVP into the basic composition of such a base material for generating aroma to be heated, and by adding an appropriate amount and an appropriate amount of microcrystalline cellulose, the material to be heated is heated. The quality of the aroma generating substrate can be further improved as described above.

In order to enjoy the refreshing sensation of the refreshing agent and prevent its dissipation over time, the cooling agent and the crosslinked PVP are contained in an amount of 1 to 10% by mass and 2 to 10% by mass, respectively, in the base material for generating aroma to be heated. The content is required, and the crosslinked PVP needs to be 1 to 6 times the content of the refreshing agent. Further, in order to mix the refreshing agent and the crosslinked PVP, it is necessary to dissolve the refreshing agent in a lower alcohol and then mix with the crosslinked PVP. In such a content and mixing method, the aroma of the refreshing agent during smoking can be enjoyed, the crosslinked PVP can absorb the refreshing agent, and these can be prevented from being dissipated over time. A quantitative index that can determine that the heat-heated aroma-generating base material has this dissipation-preventing effect is the conventional heat-heated aroma-generating base material of the present invention using menthol as a cooling agent. It was found by comparing with the base material. This is an environment in which the relative humidity is 65% RH at 17 ° C., and the content of menthol in the heated aroma generating base material, which is precisely weighed about 5 g to 10 g, is d (0), and the heated aroma generating base material is precisely weighed. Is defined as d (24) after being left at 5 ° C. for 24 hours, and d (48) as the mass of the heated aroma generating base material after being left at 5 ° C. for 48 hours. When the reduction rate of menthol is d = {(d (24) −d (48)} / d (0) and d ≦ 0.20, the effect of preventing the dissipation of menthol becomes remarkable. Therefore, the present invention. The base material for generating aroma to be heated is characterized in that its menthol reduction rate d is d ≦ 0.20. It exerts a preventive effect.

The microcrystalline cellulose improves the strength of the aroma-generating base material to be heated, and can effectively prevent the aroma-generating base material to be heated from falling off, falling, and deforming before and after smoking and after long-term storage. In the sheet production of the aroma-generating base material to be heated by the compression / shearing method, in order to effectively prevent the cohesive fracture of the sheet and the adhesion to the metal roll, 2 in the aroma-generating base material to be heated. It is necessary to contain ~ 15% by mass. Within this content range, such effects of microcrystalline cellulose can be achieved, but moreover, microcrystalline cellulose has an average particle size of 70 μm or more and 120 μm or less and / or 20,000 or more and 60, A mass average molecular weight (Mw) of 000 or less is more effective, and the residual amount on the sieve having a mesh size of 250 μm or less of 8% by mass or less with respect to the total amount of microcrystalline cellulose is based on the total amount of microcrystalline cellulose. It is even more effective to use microcrystalline cellulose having a particle size distribution of 45% by mass or more and a residual amount on the sieve having a mesh size of 75 μm and a narrow particle size distribution.

Since the microcrystalline cellulose does not dissolve in water, lower alcohol, aerosol former, etc., it can be treated in the same manner as the aromatic source material. Therefore, it is preferable to mix the microcrystalline cellulose together with the aromatic source material and the aerosol former.

In the present invention, the microcrystalline cellulose can improve the strength of the heated aroma generating base material and prevent the heated aroma generating base material from falling off, falling, deforming, etc. before and after smoking and after long-term storage. In the production of a sheet of a fragrance-generating base material to be heated by a compression / shearing method, the fragrance-generating base material to be heated has an effect of preventing cohesive failure of the sheet and adhesion to a metal roll. A quantitative index was found that could be used to determine that.

It is characterized in that it is produced from a second mixing step of mixing a second binder with the mixture and a molding step of molding the mixture produced in the second mixing step into a substrate to generate aroma to be heated. .. It is not clear why such a manufacturing process of stepwise mixing of different binders is preferable, but as described above, the cellulosic first binder is a uniform mixture of the aromatic source material and the aerosol former. It is believed that this is because the second polysaccharide-based binder forms a gel state that enhances the binding of these, after promoting dispersion to form a stable sol state.

Secondly, the method for producing a heated aroma generating base material of the present invention is produced by a first mixing step of mixing an aroma source material, an aerosol former, and a first binder, and a first mixing step. It is characterized in that it is produced by a mixed molding step of molding a second binder into a substrate to be heated while mixing the mixture.

As described above, in this curing step, the degree of dispersion of the aromatic source material in the sol state formed by the cellulosic first binder promoting uniform mixing and dispersion of the aromatic source material and the aerosol former is determined. It is presumed to have the effect of enhancing and stabilizing. This is because an increase in the volume of the mixture is observed in the curing process. If the temperature is lower than 15 ° C, the volume increase is slight, and the effect of the curing step on the quality of the aroma-generating substrate to be heated is not recognized. If the temperature exceeds 30 ° C, the cause is unknown, but the mixture is gelled. Will be recognized.

The cartridge will be described.

The heated fragrance generating source constituting the heated fragrance cartridge of the present invention is characterized by being a single heated fragrance generating base material or an aggregate of the heated fragrance generating base materials. In the case of a single substance, the heat aroma generating source is preferably in the form of a sheet, and in the case of an aggregate, it is preferable that an appropriate amount of the sheet-shaped or cut base material for generating the aroma to be heated is bundled. In particular, the shape of the cut base material for generating aroma to be heated is not limited to prismatic, flat plate, columnar, granular or the like, but is preferably prismatic from the viewpoint of forming a gas flow path. However, in order to secure a more sufficient gas flow path in either the sheet shape or the prismatic shape, the heated fragrance cartridge provided with the heated fragrance source is heated so that the voids are communicated with each other in the long axis direction. It is required to be a source of aroma to be heated in which an aroma generating base material is arranged.

Such a heated fragrance generating source may be stored as it is in an exterior member that wraps the entire heated fragrance cartridge, but it is wrapped by a heated fragrance generating base material wrapping member that is a tubular scroll. May be good. In the former case, the base material for generating a fragrance to be heated is packed in the exterior member, but in the latter case, for example, it is only necessary to wrap the base material with the exterior member, which is efficient in manufacturing the fragrance to be heated cartridge. As the wrapping member for the aroma generating base material to be heated, paper of the prior art can be used, but in the case of a heating type smoking tool equipped with a blade type heat source by a heater, it does not come into contact with the heat source, and the aroma generating base material to be heated is used. Plastic films are more suitable because they require aerosol former resistance. In particular, from the viewpoint of environmental protection, a biodegradable plastic film is more preferable. Plastics include plastics such as polyolefins, polyesters and nylons and engineering plastics, and biodegradable plastics include poly (3-hydroxybutyrate) (PHB), poly (ε-caprolactone) (PCL) and poly (butylene). Succinate) (PBS), poly (L-lactide) (PLA) and the like can be mentioned. However, in the case of an omnidirectional heat source by electromagnetic induction heating, the entire heated fragrance generating source of the heated fragrance cartridge is heated to about 240 ° C. Therefore, when plastic is used as the heated fragrance generating base material wrapping member, It is necessary to apply a special engineer plastic film having heat resistance equivalent to that of cellulose fibers (constituting paper) in which glass transition or thermal decomposition is started at about 300 ° C, that is, a glass transition temperature of 240 ° C or higher. .. Examples of such special engineering plastics include polyamide-imide, polyarylate, polyimide, polytriazine, and liquid crystal polymer.

Next, in the heated fragrance generating cartridge of the present invention, the heated fragrance generating source is housed in the heated fragrance cartridge exterior member which is a tubular body, and the heated fragrance cartridge exterior member itself forms the mouthpiece. It is characterized by. Like cigarettes, the heated fragrance cartridge contains carbon monoxide, nicotine, tar, etc., which are contained in the gas component and particle component contained in the smoke generated by the combustion of tobacco leaves and wrapping paper, and which have an adverse effect on the body. The mouthpiece may be simply hollow, as it does not necessarily require a filter member to filter the components. However, since the exterior member of the aromatic cartridge to be heated, which is a tubular body, needs to have sufficient strength to be held in the mouth, it is more preferable to use thick paper, or plastic or engineering plastic having an appropriate thickness. In terms of environmental protection, a biodegradable plastic film is even more preferable. As the plastic and the biodegradable plastic, those mentioned in the heating aroma generating base material wrapping member can be used. However, this is also applicable in the case of 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, the heated fragrance of the heated fragrance cartridge is generated. Since the entire source is heated to about 240 ° C., when plastic is used as the exterior member of the heated aromatic cartridge, it is necessary to apply a special engineer plastic having a glass transition temperature of 240 ° C. or higher as described above.

Further, the heated fragrance cartridge of the present invention may be configured such that the mouthpiece is attached in the longitudinal direction of the heated fragrance source and is housed in the outer member of the heated fragrance cartridge which is a tubular body. Yes, for the same reason, the mouthpiece may be just a hollow tube. In this case, the thin paper used for conventional cigarettes can be used as the exterior member of the aromatic cartridge to be heated, but the hollow tube must be thick paper or plastic or engineering plastic having an appropriate thickness. Is more preferable, and in terms of environmental protection, a biodegradable plastic film is even more preferable. In this case as well, as already described, it is necessary to select a plastic suitable for the heat source for the exterior member of the aromatic cartridge to be heated.

In any of these mouthpieces, a support member for preventing the source of aroma to be heated due to smoking from moving toward the mouthpiece, cooling that actively cools volatile substances of the aerosol former to increase the amount of aerosol produced. It is preferable that the member includes at least one of a filter member that filters carbon monoxide, nicotine, tar, and other miscellaneous components generated by heating the aroma source to be heated, although the amount is small.

Further, in any of these mouthpieces, the support member and the cooling member are in this order in the longitudinal direction from the heated fragrance source side, and the support member and the filter member are in this order in the longitudinal direction from the heated fragrance source side. Then, the cooling member and the filter member are arranged in this order in the longitudinal direction from the heated fragrance source side, or the support member, the cooling member and the filter member are arranged in this order in the longitudinal direction from the heated fragrance source side. Therefore, the taste of the aroma cartridge to be heated can be adjusted in various ways.

The mouthpiece including at least one selected from the support member, the cooling member, and the filter member can be directly attached to the exterior member of the fragrance to be heated cartridge, but is a tubular scroll. It is preferable that the mouthpiece wrapping member is pre-wound to facilitate the assembly of the fragrance to be heated cartridge. Further, the support member, the cooling member, and the filter member selected to be attached to the mouthpiece may be individually wrapped with a mouthpiece wrapping member which is a tubular scroll. For such a member 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 biodegradable plastic is particularly preferable.

Further, forming at least one or more holes on the outer peripheral surface of the mouthpiece is also an effective means for adjusting the taste, suction amount and the like of the aroma cartridge to be heated.

According to the heated fragrance generating base material of the present invention, when the heated fragrance cartridge provided with the heated fragrance source composed of the heated fragrance generating base material is attached to or detached from the heated smoking equipment, the heated fragrance generating base material is deformed or dropped off. In smoking, the fragrance volatilized from the heated fragrance source material can be fully enjoyed without causing problems such as dropping, and in the production of the heated fragrance generating base material, the fragrance source material can be sufficiently enjoyed. , Aerosolformer and binder are uniformly dispersed and bound, and have the toughness and strength required for molding, so stable production is possible.

Further, the base material for generating aroma to be heated of the present invention is characterized in that when a refreshing agent such as menthol or xylitol is added as an aromatic agent, the dissipation of the cooling agent over time is suppressed, and the present invention contains the same. Even after the heated fragrance cartridge equipped with the heated fragrance generating source is stored for a long period of time, the effect of being able to fully enjoy the fragrance of the heated fragrance generating base material when it is attached to a heated smoking device and smoked is achieved. Play.

Further, the heated fragrance generating base material of the present invention is characterized in that the dimensional change due to drying is small, and a heated fragrance cartridge provided with a heated fragrance generating source composed of the substrate is attached to a heated smoking device. Even after smoking, the heated fragrance generating base material does not fall off or fall from the heated fragrance cartridge, and even after long-term storage, the heated fragrance generating base material does not fall off or fall from the heated fragrance cartridge. It has excellent handleability and has the effect of preventing contamination of the heat source of heat-not-burn smoking equipment.

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 are made without departing from the gist of the present invention. It is possible to carry out the above, and it is limited only by the technical idea described in the claims.

First, in order to specifically show the influence of the type of binder and the method of adding the binder, experiments of Examples 1 to 10 and Comparative Examples 1 to 4 were carried out.
<< Example 1 >>

A base material for generating aroma to be heated was produced by the method shown in FIG. 9 in which methyl cellulose and sodium carboxymethyl cellulose (CMC), which are the first binders, and glucomannan, which is a second binder, are mixed stepwise. Xylitol as a refreshing agent was added in the first mixing step. Therefore, the xylitol aqueous solution is
It was produced by mixing and stirring 100 parts by mass of xylitol and 400 parts by mass of water.

On the other hand, black tea leaves and Jiaogulan leaves, which are fragrance source materials, are dried at 70 ° C., crushed, and passed through an 80 mesh sieve so that the water content is about 2% by mass. board. The 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 water content while avoiding the dissipation of the required flavor components. Further, it is more preferably 65 ° C. or higher and 75 ° C. or lower. Further, in order to facilitate dispersion in the first mixing step, the dried pulverized product needs to absorb water, and the water content is preferably 5% by mass or less, preferably 3% by mass or less. More preferably, it is more preferably 0.1% by mass or more.

In the first mixing step shown in FIG. 9,
80 parts by mass of dried crushed tea leaves 20 parts by mass of dried crushed leaves of Amachazuru Glycerin 30 parts by mass propylene glycol 30 parts by mass Methyl cellulose 15 parts by mass Carboxymethyl cellulose sodium (CMC) 4 parts by mass Xylitol / aqueous solution 8 parts by mass Was put into a mixer and mixed for 15 minutes to produce a first mixture.

This first mixture was put into a mixing molding step that also serves as a second mixing step of mixing with a second binder and a first molding step of molding into a sheet-like heat-treated aroma generating substrate. In this mixing molding step, the doctor blade is pressed against a roll to form a sheet while adding 0.5 part by mass of glucomannan and 20 parts by mass of water, which are the second binders, to 100 parts by mass of the first mixture. By repeating the three roll mills, a second mixture which is a composition of the aroma generating base material to be heated is produced, and at the same time, it is molded into a sheet-shaped aroma generating base material to be heated. In Example 1, in this mixed molding step, the roll interval, the speed ratio between rolls, and the like were adjusted so that the moisture evaporates appropriately and the sheet-like aroma-generating base material having a thickness of 0.3 mm is formed. The 3-roll mill was repeated 8 times. In this mixing molding step, the second mixing step (100 parts by mass of the first mixture, 0.5 parts by mass of glucomannan as the second binder, and 20 parts by mass of water in the production method shown in FIG. 8 is performed. (Mixing process) and the first forming process of forming into a sheet by a three-roll mill have the advantage of simplifying the manufacturing process shown in FIG. 8, but the resulting sheet-like heated aroma generating base material is produced. There is no difference in the mixed and dispersed states of.

Next, in the second molding step shown in FIG. 9, the sheet is cut into rectangles having a length of 150 mm and a width of 240 mm, and finally, using a rotary cutter, the sheet has a length of 240 mm, a width of 1.5 mm, and a thickness of 0. It was cut into a 3 mm shape to produce a long rectangular columnar heated aroma generating base material. The vertical and horizontal directions of this sheet are parallel and vertical to the rotation axis of the roll, respectively.

The 50 long prismatic heated fragrance generating base materials 3211 (FIG. 3) produced in this manner are aligned in the longitudinal direction and have a basis weight of 34 g / m ^{2 as the heated fragrance generating base material wrapping member 322.} A columnar scroll having an outer diameter of 6.9 mm was produced by being rolled up and glued using the paper of the above, and then cut into a length of 12.0 mm to produce a fragrance source 320 to be heated. As a result, the heated fragrance generating source 320 in which 50 heated fragrance generating base materials 3211 (FIG. 3) having a length of 12.0 mm, a width of 1.5 mm, and a thickness of 0.3 mm were wrapped around paper was heated. Each fragrance source 320 contains 0.29 g of the fragrance generating substrate aggregate 321 to be heated, and the volume filling ratio of the fragrance generating substrate aggregate 321 to be heated (FIG. 3) with respect to the volume of the fragrance generating source 320 to be heated is It was 0.60. Further, in the heated aroma generating base material 3211 (FIG. 3), 60 parts by mass of the aerosol former and 15 parts by mass of methyl cellulose and CMC, which are the first binders, are each based on 100 parts by mass of the aroma source material. And 4 parts by mass, 0.9 parts by mass of glucomannan, which is a second binder, is contained.

Here, the heated aromatic generator base wrapping member 322 wound around the heated aromatic generator substrate assembly 321 need not be paper, equivalent to paper having a basis weight of ^30g / ^{m 2 ~40g} / m 2 A strong plastic film can be used. As will be described later, the heat-not-burn aroma-generating base material wrapping member 322 does not come into contact with the heat source of the heat-not-burn smoking equipment, and is an aerosol former that is also an organic solvent contained in the heat-not-burn aroma-generating base material 3211 (FIG. 3). Therefore, it is preferable to use a plastic film corresponding to the strength 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 heated aroma generating base material wrapping members of Examples and Comparative Examples shown below. However, this is a material that can be selected for a heated fragrance cartridge that is used by being attached to a heated smoking device equipped with a blade-type heat source.

In Examples 1 to 5 and Comparative Examples 1 and 2, the heat source having such an outer diameter and length is processed into a blade-type heat source using a heater in the smoking test described later. This is because Aikos (registered trademark, manufactured by Philip Morris Co., Ltd.) equipped with the above is used as a heating type smoking tool.
<< Example 2 >>

Example 2 has exactly the same composition as that of Example 1, but in order to specifically show the effect of curing, a base material for generating aroma to be heated was produced according to a production process in which the curing process shown in FIG. 10 was added. Up to the first mixing step, the first mixture is produced in the same manner as in Example 1, but before the mixing molding step that combines the second mixing step and the first molding step, the first mixture is prepared. It was sealed with a polyethylene bag and provided with a curing process at 20 ° C. for 144 hours (6 days). By going through this curing process, the apparent volume is increased by about 1.5 times, and it can be visually observed that the curing mixture after the curing process releases less crushed tea than before the curing. It was observed by observation. From this phenomenon, it is considered that the curing improved the dispersion of the aromatic source material, the aerosol former, and the first binders, methyl cellulose and CMC.

In the curing mixture produced in this manner, the aroma generation source 320 to be heated was produced through a mixing molding step and a second molding step in the same manner as in Example 1. As a result, 50 heated aroma generating base material aggregates 321 having 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 aroma generating base material wrapping member 322. The heated fragrance source 320 contains 0.29 g of the heated fragrance generating base material aggregate 321 per unit of the heated fragrance generating source 320, and the heated fragrance generating base material aggregate with respect to the volume of the heated fragrance generating source 320. The volume filling rate of the body 321 was 0.60. Further, as in Example 1, in the heated aroma generating base material 3211 (FIG. 3), 60 parts by mass of the aerosol former and methyl cellulose and CMC as the first binder were added to 100 parts by mass of the aroma source material. , 15 parts by mass and 4 parts by mass, respectively, and 0.9 parts by mass of glucomannan, which is a second binder.
<Comparative example 1>

In Comparative Example 1, in order to specifically show the effect of the addition of the first binder and the second binder in two steps, the second binder, glucomannan, was used instead of the mixed molding step of Example 1. , Aroma-generated source to be heated was produced in the same manner as in Example 1 except that methylcellulose and CMC, which are the first binders, were mixed at the same time in the first mixing step.

The xylitol aqueous solution for adding xylitol as a cooling agent in the first mixing step is
It was produced by mixing and stirring 100 parts by mass of xylitol and 400 parts by mass of water. On the other hand, the leaves of black tea and the leaves of Jiaogulan, which are the aromatic source materials, were dried at 70 ° C., crushed, and passed through an 80 mesh sieve. The water content of these dried pulverized products was about 2% by mass.

In the first mixing step,
80 parts by mass of dried crushed tea leaves 20 parts by mass of dried crushed leaves of Amachazuru 30 parts by mass of glycerin 30 parts by mass of propylene glycol 15 parts by mass of methyl cellulose Sodium carboxymethyl cellulose (CMC) 4 parts by mass 0.9 parts by mass of glucomannan Part xylitol / aqueous solution 8 parts by mass 37 parts by mass of water was put into a mixer and mixed for 15 minutes to prepare the first mixture.

Unlike the first embodiment, the first mixture produced in this manner does not mix the second binder, and repeats a three-roll mill in which a doctor blade is pressed against a roll to form a sheet. The three-roll mill, which was put into the molding step of 1 and the roll interval and the speed ratio between rolls were adjusted, was repeated 8 times to form a sheet-like aroma-generating substrate having a thickness of 0.3 mm in which water was appropriately evaporated. Was done.

Then, as in Example 1, a heated aroma generation source was produced through a second molding step. As a result, 50 heated aroma generating base material aggregates 321 having 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 aroma generating base material wrapping member 322. The heated fragrance generating source 320 contains 0.29 g of the heated fragrance generating base material aggregate 321 per one heated fragrance generating source 320, and the heated fragrance generating base material with respect to the volume of the heated fragrance generating source 320. The volume filling rate of the aggregate 321 was 0.60. Further, as in Example 1, in the heated aroma generating base material 3211 (FIG. 3), 60 parts by mass of the aerosol former and methyl cellulose and CMC as the first binder are added to 100 parts by mass of the aroma source material. , 15 parts by mass and 4 parts by mass, respectively, and 0.9 parts by mass of glucomannan, which is a second binder.
<< Example 3 >>

In order to specifically show that the effect of the present invention does not depend on the cross-sectional shape perpendicular to the longitudinal direction of the aroma generating substrate to be heated, Example 3 has a width of the aroma generating substrate to be heated as compared with Example 2. And the thickness was reduced. In exactly the same manner as in Example 2, the second mixture is produced in the mixed molding step that combines the second mixing step and the first molding step through the first mixing step and the curing step, and the sheet-like heat to be heated. It was molded into an aroma generating substrate. However, in Example 3, the position of the doctor blade, the roll interval, the speed ratio between rolls, and the like were adjusted differently from those in Example 2 by repeating the three-roll mill eight times to obtain a sheet having a thickness of 0.1 mm. It was molded into a base material for generating aroma to be heated. Next, in the second molding step, as in Example 1, after cutting into a rectangle having a length of 150 mm and a width of 240 mm, a rotary cutter is used to make a length of 240 mm, a width of 1.0 mm, and a thickness of 0.1 mm. It was cut into a shape to produce a long rectangular columnar heated aroma generating substrate.

In the case of this heated aroma generating base material, 225 pieces are aligned in the longitudinal direction ^{, wrapped with paper having a basis weight of 34 g / m 2} , wrapped, and glued to form a circle with an outer diameter of 6.9 mm. After the columnar scroll was manufactured, it was cut to a length of 12.0 mm. As a result, 225 aggregates of heated aroma generating base material having a length of 12.0 mm, a width of 1.0 mm, and a thickness of 0.1 mm are wound around a paper-made heated aroma generating base material wrapping member 322. The heated aroma generating source 320 contains 0.29 g of the heated aroma generating base material aggregate 321 per one heated aroma generating source 320, and the heated aroma generating base material set with respect to the volume of the heated aroma source 320. The volume filling rate of the body 321 was 0.60. Naturally, the composition of the aroma generating base material 3211 (FIG. 3) to be heated in this case is also the same as in Examples 1 and 2 and Comparative Example 1.
<< Example 4 >>

In Example 4 as well, in order to specifically show that the effect of the present invention does not depend on the cross-sectional shape perpendicular to the longitudinal direction of the aroma generating base material to be heated, the width of the aroma generating base material to be heated is compared with that of Example 2. And increased the thickness. In exactly the same manner as in Example 2, the second mixture is produced in the mixed molding step that combines the second mixing step and the first molding step through the first mixing step and the curing step, and the sheet-like heat to be heated. It was molded into an aroma generating substrate. However, in Example 4, the position of the doctor blade, the roll interval, the speed ratio between rolls, and the like were adjusted differently from those in Example 2, and the three-roll mill was repeated eight times to obtain a sheet having a thickness of 0.5 mm. It was molded into a base material for generating aroma to be heated. Next, in the second molding step, as in Example 1, after cutting into a rectangle having a length of 150 mm and a width of 240 mm, a rotary cutter is used to obtain a length of 240 mm, a width of 2.0 mm, and a thickness of 0.5 mm. It was cut into a shape to produce a long rectangular columnar heated aroma generating substrate.

In the case of this heated aroma generating base material, 23 pieces are aligned in the longitudinal direction ^{, wrapped in paper having a basis weight of 34 g / m 2} , wrapped, and glued to have an outer diameter of 6.9 mm. After the columnar scroll was manufactured, it was cut to a length of 12.0 mm. As a result, 23 heated aroma generating base materials 321 having 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 heated aroma generating base material wrapping member 322. The heated fragrance source 320 contains 0.30 g of the heated fragrance generating base material aggregate 321 per unit of the heated fragrance source 320, and the heated fragrance generating base material aggregate 321 with respect to the volume of the heated fragrance source 320. The volume filling rate of was 0.62. Naturally, the composition of the aroma generating base material 3211 (FIG. 3) to be heated in this case is also the same as in Examples 1 and 2 and Comparative Example 1.
<Comparative example 2>

In Comparative Example 2, in order to confirm the effect of the second binder, an attempt was made to produce a base material for generating aroma to be heated in the same manner as in Comparative Example 1 without using glucomannan, but a three-roll mill was used. In the first molding step used, it was found that glucomannan was an indispensable binder for the aroma-generating base material to be heated and its production because it was difficult to form a sheet due to breakage and peeling. However, in order to carry out the smoking test, an aroma source to be heated having the same size as that of Examples 1 and 2 and Comparative Example 1 was produced.
<< Example 5 >>

In Example 5, a curing process was added to the manufacturing process of Comparative Example 1 in order to specifically show the magnitude of the influence of curing. That is, the first mixture in Comparative Example 1 was sealed with a polyethylene bag, and a curing step was provided at 20 ° C. for 144 hours (6 days). By going through this curing process, the apparent volume is increased by about 1.4 times, and it can be visually observed that the curing mixture after the curing process releases less crushed tea than before the curing. It was observed by observation. Finally, 50 pieces of the aroma-generating base material aggregate 321 to be heated, which are molded in the same manner as in Example 1 and have a length of 12.0 mm, a width of 1.5 mm, and a thickness of 0.3 mm, are made of paper. A heated fragrance source 320 wound around a heated fragrance generating base material wrapping member 322 is manufactured, and each heated fragrance generating source 320 contains 0.29 g of a heated fragrance generating base material aggregate 321. The volume filling ratio of the heated aroma generating base material aggregate 321 with respect to the volume of the heated aroma generating source 320 was 0.60. Further, as in Examples 1 to 4 and Comparative Example 1, the heated aromatic base material 3211 (FIG. 3) has 60 parts by mass of an aerosol former with respect to the aromatic source material, and methyl cellulose as the first binder. And CMC contain 15 parts by mass and 4 parts by mass, respectively, and 0.9 parts by mass of glucomannan, which is a second binder.

Examples 1 to 5 and Comparative Examples 1 and 2 described above were molded in order to evaluate using Aikos (registered trademark), which is a blade-type heat source using a heater, in a smoking test described later. However, the heating method, the maximum temperature reached, the configuration of the heated fragrance source and the heated fragrance cartridge, etc. differ depending on the heat source, and it is considered that the evaluation result may be affected. However, an evaluation using glow (registered trademark), which is an omnidirectional heat source by electromagnetic induction heating, was also performed.

The sheet-shaped heated aroma generating base material having a thickness of 0.3 mm, which was produced in exactly the same manner as in Example 1, was cut into a rectangle having a length of 150 mm and a width of 210 mm in the second molding step, and then a rotary cutter was used. Using, it was cut into a shape having a length of 210 mm, a width of 1.5 mm, and a thickness of 0.3 mm to produce a long rectangular columnar heated aroma generating base material.

31 of these heated aroma generating base materials are aligned in the longitudinal direction ^{, wrapped in paper having a basis weight of 34 g / m 2} , wrapped, and glued to form a columnar shape having an outer diameter of 5.5 mm.

Therefore, plastic film, engineering plastic film, and biodegradable plastic film cannot be used as a substitute material for paper. In this case, when plastic is used as the heat aroma generating base material wrapping member, the heat resistance equivalent to that of the cellulose fiber (which constitutes paper) at which glass transition or thermal decomposition is started at about 300 ° C., that is, 240 ° C. It is necessary to apply a special engineer plastic film having the above glass transition temperature. Examples of such special engineering plastics include polyamide-imide, polyarylate, polyimide, polytriazine, and liquid crystal polymer.

As described above, in order to specifically show the influence of the type of the binder and the method of addition, the sources to be heated such as Examples 1 to 10 and Comparative Examples 1 to 4 have been produced, but the types are further different. When an attempt was made to examine the blending order of the binders, in the first mixing similar to Example 1, the second binder was a polysaccharide other than the cellulosic polysaccharide instead of the first binder of the cellulosic polysaccharide. When the binder was replaced with that of the above, a partially gelled lump was formed and remained in the subsequent steps, so that a uniform heated aroma generating base material could not be produced. Was omitted.

Using the heated aroma sources of Examples 1 to 10 and Comparative Examples 1 to 4, the effect of the stepwise addition of the first binder and the second binder, and the effect and influence of curing were examined. The following evaluations 1 to 3 that can be specifically expressed were carried out.
[Evaluation 1-1]

In order to evaluate the heat-heated fragrance sources of Examples 1 to 5 and Comparative Examples 1 and 2, a heated smoking device provided with a blade-type heat source 130 using a heater manufactured by Philip Morris Co., Ltd. shown in FIG. 1 is used. A certain Aikos (registered trademark) 100 was used. The smoking tool 100 is a blade-type heat source 130 having a heat source 130 having a width of 4.5 mm, a length to the tip of 12 mm, and a thickness of 0.4 mm, and is provided on the opposite side of the body 110 from the chamber. It generates heat due to the electric power supplied from the battery (not shown) and reaches about 300 to 350 ° C. The heated fragrance cartridge 300 is mounted on the inner surface of the chamber provided in the body 110 with an inner diameter of 7.0 mm along the 120, and then is sucked 14 times by the control system built in the body 110. The heated fragrance cartridge 300 of the book can be smoked. When the heated fragrance cartridge 300 of this example and this comparative example is inserted, the length of the portion protruding outward from the body 110 is about 20 mm.

On the other hand, in the heated fragrance cartridge 300 attached to the smoking device, as shown in FIG. 1, the heated fragrance source 320, the support member 331, and the filter member 333 are wound around the heated fragrance cartridge exterior member 310. The mouthpiece 330 was reinforced with the mouthpiece reinforcing member 3301. More specifically, the length having a cylindrical through hole having a length of 12 mm, an outer diameter of 6.9 mm, a heated fragrance source 320, and an inner diameter of 4 mm manufactured in Examples 1 to 5 and Comparative Examples 1 and 2. A support member 331 which is a hollow tube having an outer diameter of 8 mm and an outer diameter of 6.9 mm, and a filter member 333 made of a cellulose acetate fiber formed into a cylindrical shape having a length of 23 mm and an outer diameter of 6.9 mm are arranged in this order in the longitudinal direction. The outer diameter of the heated fragrance cartridge exterior member 310, which is a paper ^{having a basis weight of 38 g / m 2} and which is coated with a predetermined amount of adhesive at a predetermined position on the inner surface, has an outer diameter of less than 7.0 mm. It was manufactured by being wrapped with a paper having ^{a basis weight of 40 g / m 2} having an adhesive coated on the inner surface so as to overlap with the filter member 333 of the mouthpiece 330. This is heated aroma cartridge exterior member 310 of the case, basis ^{weight, 32g / m 2 ~45g / m} 2 paper, or, be a plastic film of intensity corresponding to the paper, the minimum intensity However, it is preferable to reinforce the ^{part held by the lips with a paper having a basis weight of 40 g / m 2} or more in order to prevent damage due to the penetration of saliva. Since the heat fragrance 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. Further, the plastic film is preferable because saliva does not permeate and the mouthpiece reinforcing member 3301 is not required. 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.

In the case of the blade-type heat source 240, a drop test of the heated aroma generating base material 3211 (FIG. 3) was performed 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 aroma generating base material aggregate 321 comes into contact with the blade type heat source 240 and is heated, so that the heated aroma generating base material 3211 after smoking ( FIG. 3) is based on the fact that the heated aroma generating base material aggregate 321 during smoking tends to contaminate the blade type heat source 130 and the inner wall 120 of the chamber, while tending to shrink and easily fall. In the evaluation, the heated fragrance cartridge 300 provided with the heated fragrance source 320 manufactured in Examples 1 to 5 and Comparative Examples 1 and 2 was attached to the heated smoking device 100 provided with the blade type heat source 130. After smoking, the heated fragrance cartridge 300 is taken out, the heated fragrance source 320 is directed vertically downward, and the presence or absence of the heated fragrance generating base material 3211 (FIG. 3) is examined. rice field.

The criteria for this evaluation are as follows.
Rank A: There is no drop of the aroma generating base material to be heated, and there is little contamination of the blade type heat source and the inner wall of the chamber. Rank B: A part of the aroma generating base material to be heated falls and the blade type heat source and the inner wall of the chamber are contaminated.
Is conspicuous [Evaluation 1-2]

In order to evaluate the sources of aroma to be heated in Examples 6 to 10 and Comparative Examples 3 and 4, British American Tobacco shown in FIG. 2 as a heated smoking device provided with an omnidirectional heat source by electromagnetic induction heating. Glow (registered trademark) 200 manufactured by Tobacco Co., Ltd. was used. The smoking tool 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, and the heated fragrance cartridge 400 is attached to the heat source 240 to generate the heated fragrance source 420. It is configured to heat the surroundings of. The heat generated by the electric power supplied from the heat source control unit 250 is generated, and the temperature reached is about 240 to 280 ° C., and the smoking time is about 3 to 4 minutes. The aerosol cartridge 400 to be heated is attached to a heat source 240 having a vent hole 230 at the bottom and having an inner diameter of 5.6 mm and having a cylindrical can shape, and is then surrounded by the heat source 240 heated by the heat source control unit 250. When the aerosol former volatilizes from the heat-heated fragrance source 420 and is sucked, the air flowing in from the ventilation holes 230 cools the aerosol former to generate smoke and smoke.

On the other hand, as shown in FIG. 2, the heated fragrance cartridge 400 attached to the smoking device includes a mouthpiece 430 including a heated fragrance source 420, a cooling member 432, a filter member 433, and a hollow tube 434. Was wrapped around the exterior member 410 of the aromatic cartridge to be heated. More specifically, the heated fragrance source 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 thick paper, a filter member 433 made of a cellulose acetate fiber formed into a cylindrical shape having a length of 8 mm and an outer diameter of 5.5 mm, and a length of 8 mm and a thickness of 8.5 mm. Hollow tubes 434, which are formed by winding 0.5 mm thick paper and having a cylindrical shape with an outer diameter of 5.5 mm, are brought into contact with each other in the longitudinal direction in this order, and a predetermined amount of adhesive is applied to a predetermined position on the inner surface. A heated fragrance cartridge exterior member 410, which is a paper having a length of 20 mm and a width of 83 mm and a basis weight of 38 g / m ² , was wound so as to have an outer diameter of less than 5.6 mm.

In the case of the omnidirectional heat source 240, the insertion test of the heated fragrance cartridge 400 was performed to confirm the effects of the binder and curing. As shown in FIG. 2, in the case of the cylindrical can-shaped omnidirectional heat source 240, the elongated cylindrical can is attached so that the elongated heated fragrance cartridge 400 is inserted, so that the heated fragrance cartridge 400 can be attached. It is based on the fact that it is difficult and in some cases can lead to its damage. The evaluation was performed by asking five subjects about the feeling of wearing the heated fragrance cartridge 400 on the heat-not-burn smoking device 400 when smoking.

The criteria for this evaluation are as follows.
Rank A: No problem with mounting the fragrance to be heated Rank B: It is difficult to mount the fragrance to be heated, and in some cases it is damaged [Evaluation 2-1]

In the smoking carried out in [Evaluation 1-1], a sensory survey was conducted by 5 subjects to confirm the effects of the binder and curing. Sensory studies were specifically focused on the delicate aromas of tea.

The criteria for this evaluation are as follows.
Rank A: Level at which you can enjoy the aroma of tea when smoking Rank B: Level at which the aroma of tea is unsatisfactory when smoking [Evaluation 2-2]

In the case of the omnidirectional heat source 240, as in the case of the blade type heat source 130, five subjects smoked in the state shown in FIG. 2 and conducted a sensory survey to confirm the effects of the binder and curing. In this case as well, a sensory survey was conducted focusing on the delicate aroma emitted by teas.

The criteria for this evaluation are as follows.
Rank A: Level at which you can enjoy the aroma of tea when smoking Rank B: Level at which the aroma of tea is unsatisfactory when smoking [Evaluation 3]

In evaluations 1 and 2, the effects of the binder and curing were confirmed by a drop test of the aroma generating substrate to be heated, an insertion test of a aroma cartridge to be heated, and a smoking test, and these effects were confirmed in Example 1. It was found that there is a correlation with the mechanical strength of the sheet-shaped heated aroma generating base material produced in 10 and 10 and Comparative Examples 1 to 4.

Actually, the sheet-shaped heated aroma generating base material of Examples 1, 2, 5, 6, 7, and 10 and Comparative Examples 1 to 4 manufactured to a thickness of 0.3 mm was used, and laterally. A general tensile strength test was performed using a test piece cut into 10.0 cm and 22.0 cm in length, and the measured breaking strength was evaluated. The tensile strength test was performed in a test environment of 20 ° C. and 50% RH, with the distance between the clamps sandwiched in the vertical direction of the test piece being 20.0 cm.

As described above, the compositions of Examples 1 to 10 and Comparative Examples 1 to 4 used in the evaluations 1 to 3 and the addition are applied.

Table 1-1 shows the shape and number of the heated aroma generating base materials used as the thermal aroma generating source, and Table 1-2 shows the production conditions of the composition of the heated aroma generating base material and the results of evaluations 1 to 3. Shown in.

The method of adding the binder is a method in which the first binder and the second binder are added stepwise by comparing Example 1 and Comparative Example 1 and Example 6 and Comparative Example 3. Was confirmed to be preferable. In Example 1 and Comparative Example 1, a heated aroma generating group produced under exactly the same conditions except that the first binder and the second binder were added in two steps in the former and batch addition in the latter. As for the material, in the drop test and the smoking test using the heat-not-burn smoking tool 100 provided with the blade type heat source 130, the former has obtained better results. Further, Example 6 and Comparative Example 3 have the same relationship as that of Example 1 and Comparative Example 1, and in the insertion test and the smoking test using the heat-not-burn smoking device 200 provided with the omnidirectional heat source 240. Better results have been obtained with the heat-not-burn aroma-generating substrate produced from the composition produced by the two-step addition of the binder.

Although the cause of this is not clear, the first binder of the cellulosic polysaccharide promotes uniform mixing and dispersion of the aromatic source material and the aerosol former to form a stable sol state, and then the cellulosic polysaccharide. Since the second binder, which is a polysaccharide other than the above, forms a gel state that enhances these bindings, the dense dispersion enhances the volatilization of the aromatic components of tea by heating, and the binding force is contracted by heating. It is considered that the action was reduced and the mechanical strength of the aroma-generating substrate to be heated was improved. This speculation is that when the first binder and the second binder are interchanged and mixed, a partially gelled mass is formed in the mixture of the aromatic source material, the aerosol former, and the binder, and is uniformly dispersed. It is supported by the phenomenon that the state cannot be generated.

The effects of curing were as follows: Example 1 and Examples 2 to 4, Example 5 and Comparative Example 1, Example 6 and Examples 7 to 9, and Example 10 and Comparative Example 3 in which the presence or absence of curing was compared. , Evaluation 1-1, Evaluation 1-2, Evaluation 2-1 and Evaluation 2-2 are clear. Curing can greatly improve the quality of the aroma-generating substrate to be heated, as well as the addition of a stepwise binder. Further, as can be seen by comparing the evaluation results of Example 5 and Comparative Example 1 and Example 10 and Comparative Example 3, when the curing step is performed, the first binder and the second binder are gradually added. It is not necessary to add it, and it is considered that the curing effect is quite large.

Although the cause of this curing effect is not clear, the degree of dispersion of the aromatic source material in the sol state formed by promoting the uniform mixing and dispersion of the aromatic source material and the aerosol former by the cellulosic first binder. It is presumed that this is due to the increase and stabilization of. This is supported by the fact that an increase in the volume of the mixture during the curing process is observed, which depends on the temperature and time of curing. As a result, the more densely dispersed structure of the aroma source material in the aroma generating base material to be heated produced through the curing process enhances the volatilization action of the aroma component of tea by heating, and the heating of the aroma generating base material to be heated increases. It is considered that the contractile action was reduced and the mechanical strength was improved.

Further, from the evaluation results of Comparative Examples 2 and 4 to which glucomannan was not added, the polysaccharides other than the cellulosic polysaccharide used as the second binder were added in a small amount, but the aroma generating group to be heated. It is considered to be indispensable for improving the quality of materials. However, the addition of a large amount of the polysaccharide, which is the second binder, tends to destroy the dispersion system of the composition of the aroma-generating substrate to be heated and cause gelation. It is necessary to enhance the dispersibility of the aroma-generating substrate to be heated and improve the cohesiveness by using it in combination with the cellulosic polysaccharide used.

Further, in order to support the causal relationship between the drop test, the insertion test, and the smoking test, these evaluation results are based on the sheet-like coverings produced in Examples 1 to 10 and Comparative Examples 1 to 4. It was found that there is a good correlation with the breaking strength of the heated aroma generating substrate. The results are shown in Examples 1, 2, 5, 6, 7, and 10 and Comparative Examples 1 and 2 in the row of tensile tests in Table 1-2. When this evaluation 3 is collated with the evaluation results 1-1, 1-2, 2-1 and 2-2, the sheet-shaped heated aroma generating base material produced by two-step addition and curing of the binder is obtained. When the aromatic cartridge to be heated has a high breaking strength and a breaking strength of at least 5 N or more per test piece cross-sectional area (0.3 × 100 mm ² ), that is, 0.167 N / mm ^{2 or more.} It is considered that it is an index for developing the mechanical strength required for the above, low heat shrinkage after smoking, and volatility of aromatic components due to heating during smoking. This index is consistent with and correlates with the causes of the effects of gradual addition and curing of binders described above.

Secondly, the crosslinked PVP can sorb the cooling agent in a simple process, suppresses the dissipation of the cooling agent from the heat-heated aroma generating substrate over time, and contains the heat-not-burned aroma generating source. In order to specifically show the effect of being able to fully enjoy the aroma of the heat-not-burned aroma-generating base material when smoking by attaching it to a heated smoking device even after the heated aroma cartridge equipped with the above is stored for a long period of time. In addition, the experiments of Examples 11 to 18 and Comparative Examples 5 to 12 using menthol and xylitol as refreshing agents were carried out.

As a method for producing a heated aroma generating base material of the present invention, as shown in FIG. 12, a first binder and a second binder are added stepwise, and a first binder is added. It is optimal to provide a curing step between the mixing step of 1 and the second mixing step of adding the second binder. However, in the following examples and comparative examples, in order to simplify the experiment by focusing only on the verification of the effect of the crosslinked PVP, the first binder and the second binder are added all at once, and the curing step is performed. While omitted, only menthol was treated as a cooling agent. The manufacturing process in which the fourth mixing process of FIG. 12 was introduced was adopted in the process diagram of FIG. 11 in which the curing process was omitted.
<< Example 11 >>

The fourth mixing step of mixing the lower alcohol in which the cooling agent was dissolved and the crosslinked PVP was carried out as follows.
100 parts by mass of menthol Ethyl alcohol 200 parts by mass Cross-linked polyvinylpyrrolidone (PVP) Weigh 200 parts by mass, dissolve menthol in ethyl alcohol to prepare a menthol / ethyl alcohol solution, and then add cross-linked PVP to the menthol / ethyl alcohol solution. , Stirring and mixing to produce a menthol / ethyl alcohol / cross-linked PVP mixture in which the cross-linked PVP was swollen.

On the other hand, xylitol was prepared with the following compounding ratio of xylitol / aqueous solution in order to be charged into the third mixing step.
Xylitol 100 parts by mass Water 400 parts by mass

As the aroma source material, black tea leaves were used, dried at 70 ° C. so as to have a water content of about 2%, crushed, and passed through an 80 mesh sieve. In the mixing step of the above, the mixture was put into a wet mixer and treated for 15 minutes to produce a composition of a fragrance-generating base material to be heated.
100 parts by mass menthol / ethyl alcohol / cross-linked PVP mixture 25 parts by mass glycerin 30 parts by mass propylene glycol 30 parts by mass carboxymethyl cellulose sodium (CMC) 4 parts by mass methyl cellulose 15 parts by mass glucomannan 1 part by mass xylitol / 8 parts by mass of aqueous solution

The composition produced in the third mixing step was put into a three-roll mill in the first molding step. By compression due to being pushed between narrow rolls and shearing due to a difference in roll speed, kneading and dispersion were uniformly performed to produce a sheet-like aroma-generating substrate having a predetermined thickness. In the first molding step, since the composition becomes a high-viscosity paste, it was molded into a sheet by pressing the doctor blade against the roll while appropriately adding pure water while observing the state of the sheet. In this molding step, a three-roll mill in which the roll interval and the speed ratio between rolls are adjusted so that the moisture evaporates appropriately and is molded into a sheet-like aroma-generating substrate having a thickness of 0.3 mm is used eight times. It was repeated.

The sheet-shaped heated aroma generating base material produced in the first molding step was put into the second molding step, and was first cut into a rectangle having a length of 150 mm and a width of 240 mm.

The conditions for leaving the aroma cartridge to be heated in Evaluation 4-1 were set as a result of various studies on conditions under which white crystals of menthol were likely to precipitate.
[Evaluation 4-2]

It has the same purpose as Evaluation 4-1 but may be affected by the shape of the substrate for generating aroma to be heated. Therefore, the aroma to be heated produced in Examples 16 to 18 and Comparative Examples 9 to 12. Using the source, a heated fragrance cartridge 400 that can be smoked by being attached to Glow (registered trademark), which is a heating type smoking tool 200 equipped with the omnidirectional heat source 240 described in Evaluation 1-2, was manufactured. Then, 20 of the heated fragrance cartridges 400 were vertically packed in a box with the heated fragrance source 420 in contact with the bottom of a paper box having a long side of 55 mm, a short side of 12 mm, and a height of 85 mm.

Then, it was left under the same conditions as the evaluation 4-1 and then evaluated by the same method and criteria as the evaluation 4-1.
[Evaluation 5-1]

For the main purpose of determining the correlation between the precipitation test and the smoking test, a smoked fragrance cartridge subjected to the precipitation test of evaluation 4-1 was used, and smoking was performed by the method described in evaluation 1-1 and evaluated. As described in 2-1 a sensory survey on the refreshing sensation of menthol was performed by 5 subjects.

The smoking test was conducted as follows. Examples 11 to 15, as well as using a heated aroma sources produced in Comparative Example 5-8, similarly to the evaluation 1-1, the heated aroma cartridge 300 is manufactured, 20 of the heated aroma cartridge 300 The book was vertically packed with the heated fragrance source 320 in contact with the bottom of a paper box having a long side of 70 mm, a short side of 14 mm, and a height of 45 mm. In this smoking test, the box thus packed with the aroma cartridge to be heated was left at 25 ° C. for 2 weeks, similar to the conditions for storage by a normal smoker. Then, the subjects compared the refreshing sensation of menthol using the heated fragrance cartridge before and after leaving. The evaluation criteria are as follows.
Rank A: No change in the refreshing feeling of menthol before and after leaving Rank B: The refreshing feeling of menthol after leaving is slightly lower than before leaving Rank C: The refreshing feeling of menthol after leaving is clearly lower than before leaving [Evaluation] 5-2]

Regarding the smoking test, in addition to the same purpose as the evaluation 5-1, the shape of the heated fragrance generating base material, the configuration of the heated fragrance cartridge, the method of the heat source of the heated smoking equipment, and the associated heated fragrance generating source. Since there is a high possibility that it will be affected by the shape of the above, it is described in Evaluation 1-2 using a heated fragrance cartridge in which the precipitation test of Evaluation 4-2 was carried out for the purpose of confirming the presence or absence of these effects. Smoking was performed according to the above method, and a sensory survey on the refreshing sensation of menthol was performed by 5 subjects as described in Evaluation 2-2.

The smoking test was conducted as follows. Examples 16 to 18, as well as using a heated aroma sources produced in Comparative Example 9-12, as well as evaluation 2-1, the heated aroma cartridge 400 is manufactured, 20 of the heated aroma cartridge 400 The book was vertically packed with the heated aroma source 420 in contact with the bottom of a paper box having a long side of 55 mm, a short side of 12 mm, and a height of 85 mm. In this smoking test, the box thus packed with the aroma cartridge to be heated was left at 25 ° C. for 2 weeks, similar to the conditions for storage by a normal smoker. Then, the subjects compared the refreshing sensation of menthol using the heated fragrance cartridge before and after leaving. The evaluation criteria are as follows.
Rank A: No change in the refreshing feeling of menthol before and after leaving Rank B: The refreshing feeling of menthol after leaving is slightly lower than before leaving Rank C: The refreshing feeling of menthol after leaving is clearly lower than before leaving [Evaluation] 6]

By grasping the correlation between the precipitation test and the smoking test, the factors that reveal the results of the smoking test are clarified, and the precipitation test and the smoking test do not require the smoking test in which a heated fragrance cartridge needs to be manufactured. It is considered possible to judge the result of the smoking test by the test. However, the precipitation test is left to the number of white crystals of menthol precipitated on the end face of the heated fragrance generating base material of the heated fragrance generating source, and does not depend on the internal state of the heated fragrance generating source. Therefore, the menthol reduction rate was measured in order to find a criterion for more accurately determining the results of the smoking test.

The menthol reduction rate is that of the menthol contained in the heated aroma generating base material when the heated aroma generating base material immediately after production is precisely weighed by about 5 g to 10 g in an environment of 17 ° C. and a relative humidity of 65% RH. Let the mass be d (0), and calculate from the composition of the components constituting the aroma generating substrate to be heated. The menthol reduction rate d is determined by the mass of the precisely-scaled aroma-generating substrate to be heated after being left at 5 ° C. for 24 hours as d (24) and the mass after being left at 5 ° C. for 48 hours. It was defined as (48) by the following equation (1). Here, the reason for subtracting d (48) from d (24) in the above formula is that when the progress of the precipitation test of menthol was observed in detail, precipitation of white crystals was observed after 24 hours, so other than menthol. It is significant that the dissipation component can be eliminated and the dissipation of menthol can be reflected better.
d = {(d (24) -d (48)} / d (0) (1)

As described above, the compositions of Examples 11 to 18 and Comparative Examples 5 to 12 used in the evaluations 4 to 6, and the shape and number of the heated aroma generating base materials used as the heated aroma generating source are shown in Table 2-. Table 2-2 shows the production conditions of the composition of the aroma generating base material to be heated and the results of evaluations 4 to 6.

As is clear from the results in Table 2-2, regardless of the physical characteristics of the heat-not-burn aroma-generating base material, such as the cross-sectional shape, length, and number of the heat-not-burn aroma-generating base material perpendicular to the longitudinal direction, and Regardless of the heat source method of the heat-not-burn smoking device, there is a good correlation between the precipitation test, the smoking test, and the menthol reduction rate. In particular, when the reduction rate of menthol is 0.200 or less, the crosslinked PVP can sorb menthol and effectively prevent the menthol from being dissipated over time. Then, such a heated aroma generating base material can be produced by cross-linking PVP as a menthol / ethanol solution in which menthol is dissolved in ethanol in order to mix menthol with the composition of the heated aroma generating base material. This is only the one to which the method for producing a base material for generating a fragrance to be heated, which is provided with a step of mixing with and, is applied. Further, the content of menthol is 1 to 10% by mass in the base material for generating fragrance to be heated, the content of crosslinked PVP is 2 to 10% by mass in the base material for generating fragrance to be heated, and menthol is used. In particular, when the content is 1 to 6 times the content of menthol, it is possible to prevent the menthol from being dissipated over time.

The crosslinked PVP capable of preventing such menthol from being dissipated over time is a cooling agent other than menthol, for example, menthol, and menthol derivatives such as mentyl ether, mentyl ester, and mentyl carbonate, and menthol derivatives. Menton and its derivatives, and mentan and its derivatives, as well as mentancarboxylic acid-N-ethylamide [WS3], Nα- (menthancarbonyl) glycine ethyl ester [WS5], mentancarboxylic acid-N- (4-cyanophenyl). Mentancarboxylic acid amides such as amides, mentancarboxylic acid-N- (4-cyanomethylphenyl) amides, and mentancarboxylic acid-N- (alkoxyalkyl) amides, and methyldiisopropylpropionic acid amides [2,3-dimethyl]. 2,3-Dimethyl-2- (2-propyl) -butyric acid derivatives such as -2- (2-propyl) -butyric acid-N-methylamide [WS23], and (l (-)-isopregol, l (-). -Isopregol and its esters such as isopregol acetate, N- (2- (pyridin-2-yl) ethyl) -3-p-mentanecarboxyamide, (1R, 2S, 5R) -N- (4-methoxyphenyl) ) -5-Methyl-2- (1-isopropyl) cyclohexane-carboxamide [WS12], carboxamides such as oxamate, and L-carboxylic, xylitol, timol, spiranthol, etc. have been confirmed to be effective. ..

Third, by including microcrystalline cellulose in the aroma generating substrate to be heated, the aroma source material and the aerosol former are repeatedly compressed and sheared in order to be uniformly mixed and dispersed via the binder, for example. 3. In the sheet molding process using a three-roll mill or the like, it is possible to effectively prevent the sheet from coagulating fracture and adhesion to the metal roll, and to reduce the volume shrinkage over time due to drying of the material to be heated aroma. Since it acts as a reinforcing material and improves the strength of the aroma-generating base material to be heated, it is possible to prevent the aroma-generating base material to be heated from falling off, falling, and deforming before and after smoking and after long-term storage. In order to show the above, the experiments of Examples 19 to 26 and Comparative Examples 13 to 18 were carried out.
<< Example 19 >>

Similar to Examples 11 to 13 and Examples 16 to 18, black tea leaves and aerosol formers as aromatic sources, CMC and glucomannan as binders, menthol and xylitol as refreshing agents, and a scavenger of cooling agents. In this example, microcrystalline cellulose was used instead of methyl cellulose, and its effect was confirmed. These were collectively put into a mixer at the following compounding ratio, and a composition of a base material for generating aroma to be heated was produced by stirring and kneading for 15 minutes.
100 parts by mass glycerin 30 parts by mass propylene glycol 30 parts by mass carboxymethyl cellulose sodium (CMC) 4 parts by mass glucomannan 1 part by mass microcrystalline cellulose 15 parts by mass crosslinked polyvinylpyrrolidone (PVP) 10 parts by mass menthol 5 Parts by mass Xylitol 1.5 parts by mass

The black tea leaves were dried at 70 ° C., crushed, and passed through an 80 mesh sieve so that the water content was about 2% by mass. Further, as the microcrystalline cellulose, one having an average particle size of 90 μm and a mass average molecular weight (Mw) of 36,000 was used. However, although the average particle size is 90 μm, the residue on the sieve with a mesh size of 75 μm is 52% by mass with respect to the total amount of microcrystalline cellulose, and the residue on the sieve with a mesh size of 250 μm is the total amount of microcrystalline cellulose. A particle size distribution of 1% by mass with respect to 1% by mass was selected, and the one in which the effect of microcrystalline cellulose was remarkably exhibited was selected.

The composition of the aroma generating base material to be heated thus produced can uniformly knead and disperse the high-viscosity paste by compression by being pushed between narrow rolls and shearing due to a difference in roll speed. Moreover, a sheet-shaped heated aroma generating base material having a predetermined thickness was produced by using a three-roll mill that can be molded into a sheet. In this embodiment, a sheet-like heated fragrance having a thickness of 0.1 mm is generated by repeating the process of pressing the doctor blade against the rolls and forming the sheet shape eight times with the roll interval and the inter-roll speed ratio adjusted in advance. The substrate was manufactured. During this time, appropriate water was supplied according to the condition of the seat.

This 0.1 mm-thick sheet-shaped heated aroma-generating base material is cut into a rectangle having a length of 150 mm and a width of 240 mm, and then using a rotary cutter, it has a length of 240 mm, a width of 1.5 mm, and a thickness of 0.1 mm. A long rectangular columnar heated aroma generating base material was produced.

The 150 long prismatic heated aroma generating base materials produced in this manner are aligned in the longitudinal direction, and then paper having a ^{basis weight of 34 g / m 2 is used as the heated aroma generating base material wrapping member 322.} By being rolled up and glued, a columnar scroll having an outer diameter of 6.9 mm was produced, and then the scroll was cut into a length of 12.0 mm to produce a heat-heated aroma generator. As a result, 150 heated aroma generating base material aggregates 321 having a length of 12.0 mm, a width of 1.5 mm, and a thickness of 0.1 mm are wound around a paper-made heated aroma generating base material wrapping member 322. The heated fragrance source 320 contains 0.29 g of the heated fragrance generating base material aggregate 321 per unit of the heated fragrance generating source 320, and the heated fragrance generating base material aggregate with respect to the volume of the heated fragrance generating source 320. The volume filling rate of the body 321 was 0.60. Further, in the heated aroma generating base material 3211 (FIG. 3), 60 parts by mass of the aerosol former and 4 parts by mass and 1 part by mass of the binders CMC and glucomannan were added to 100 parts by mass of the aroma source material, respectively. It contains 15 parts by mass, 15 parts by mass of microcrystalline cellulose, 10 parts by mass of crosslinked PVP, and 5 parts by mass and 1.5 parts by mass of menthol and xylitol, respectively.

Therefore, using the composition of the aroma-generating base material to be heated, which was produced in exactly the same manner as in Example 19, a sheet-shaped aroma-generating base material to be heated was produced by using a three-roll mill in which compression and shearing were repeated. However, in Example 20, the position of the doctor blade, the roll interval, the speed ratio between rolls, and the like were adjusted differently from those in Example 19 by repeating the three-roll mill eight times to obtain a sheet having a thickness of 0.3 mm. It was molded into a base material for generating aroma to be heated.

However, in Example 21, the position of the doctor blade, the roll interval, the speed ratio between rolls, and the like were adjusted differently from those in Example 20 by repeating the three-roll mill eight times, and the thickness was 0.5 mm. It was molded into a sheet-shaped base material for generating aroma to be heated.

The evaluation criteria are as follows.
Rank A: No dropout or fall Rank B: Dropped or fallen [Evaluation 11-1]

The factors that cause the results of evaluations 7 to 10 to appear are considered as follows. Microcrystalline cellulose in the production of sheets of heated aroma generating substrates using, for example, a three-roll mill, which can form sheets by compression and shear for mixing and dispersing the aroma source material and aerosol former via a binder. Is added, the cohesive fracture of the sheet and adhesion to the metal roll are effectively prevented, and uniform mixing and dispersion are performed, so that a dense substrate to be heated aroma is generated. Be done. Further, since the microcrystalline cellulose that does not absorb a solvent such as water or ethanol exists in the substrate for generating aroma to be heated in powder form, the microcrystalline cellulose acts as a reinforcing material and is heated with excellent strength. It is considered that an aroma generating substrate is produced. Therefore, it is presumed that the heat-affected aroma-generating base material containing such microcrystalline cellulose reduces the volume shrinkage over time due to drying or the like.

Therefore, the rate of change in shape of the aroma-generating base material to be heated due to volume shrinkage due to heating and drying of the aroma-generating base material to be heated was measured, and the correlation with the evaluations 7 to 10 was examined. The specific method of the rate of change due to volume shrinkage due to heat drying is as follows. A prismatic heated aroma generating group obtained by cutting a sheet-shaped heated aroma generating base material having a thickness of 0.3 mm produced in Examples 20 and 22 and Comparative Examples 14 and 16 into a rectangle having a length of 50 mm and a width of 15 mm. A test piece was used to measure the volume shrinkage of the material. For heat drying, use a halogen moisture meter (electronic halogen moisture measuring device) (Bangxi Instrument Technology Co. Ltd., model number: DHS-50-5), and place the test piece on the sample dish of the halogen moisture meter. The test piece was heated from the upper part of the sample dish by a halogen lamp installed in the cover. The heating temperature was 105 ° C., and the length, width, and thickness of the test piece were measured at drying times of 0 minutes, 10 minutes, and 15 minutes. Using these measured values, from the definition formula of the rate of change shown in Table 4-1, the rate of change in length La (%) after 10 minutes of drying the test piece having a length of 50 mm, a width of 15 mm and a thickness of 0.3 mm was determined. Width change rate Wa (%), width change rate Wa (%), thickness change rate Ta (%), and test pieces having a length of 50 mm, a width of 15 mm, and a thickness of 0.3 mm after being dried for 15 minutes. The length change rate Lb (%), the width change rate Wb (%), the width change rate Wb (%), and the thickness change rate Tb (%) were calculated. Here, the length, width, and thickness of the test piece having a drying time of 0 minutes were adjusted by storing the test piece at a temperature of 28 ° C. to 30 ° C. and an atmosphere having a relative humidity of about 40% RH. The measured value when the amount was 15 to 20% by mass was used.
[Evaluation 11-2]

Although the purpose is the same as that of evaluation 11-1, the specific surface area of the test piece differs depending on the shape of the test piece and may affect the volume shrinkage. The shape dependence was examined. That is, as in Evaluation 1-1, the sheet-like aroma-generating base material having a thickness of 0.3 mm produced in Examples 20 and 22 and Comparative Examples 14 and 16 was used, but the length was 12 mm and the width was 1. A prismatic columnar heated aroma generating base material cut into a 5 mm rectangle was used as a measurement test piece for volume shrinkage.

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

Table 3-3 shows the compositions of Examples 19 to 26 and Comparative Examples 13 to 18 used in the evaluations 7 to 11, and the shape and number of the heated aroma generating base materials used as the heated aroma generating source. Table 1 shows the results of evaluations 7 to 11 and Table 3-2. Further, the calculated values of the shape change rate due to the volume shrinkage of the heated aroma generating base material defined in Tables 4-1 and 5-1 are shown in Tables 4-2 and 5-2.

It is clear from the comparison between Examples 19 to 22 and Comparative Examples 14 to 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. As described above, regardless of the cross-sectional shape perpendicular to the longitudinal direction of the aroma generating substrate to be heated, the aroma to be heated provided with the aroma generating substrate produced using the aroma generating substrate containing microcrystalline cellulose. Even when the cartridge was exposed to continuous drying and heat-drying due to smoking, it was possible to solve the problem of falling off or dropping of the aroma-generating base material to be heated, which is considered to be caused by volume shrinkage. This problem is different between the blade type heat source by the heater and the omnidirectional heat source by electromagnetic induction heating, regardless of the heating method, the maximum temperature reached, the composition of the heated fragrance source and the heated fragrance cartridge, and the like. It was solved by the addition of cellulose.

The effect of this microcrystalline cellulose is the generation of aroma to be heated containing 2% by mass of microcrystalline cellulose, as shown in Table 4-2 showing the rate of shape change in the test piece having a length of 50 mm, a width of 15 mm and a thickness of 0.3 mm. Length change rate La = 7.2%, width change rate Wa = 5.7%, thickness change rate Ta = 1.2% after 10 minutes drying of the base material, and length after 15 minutes drying. At least one of the change rate Lb = 8.1%, the width change rate Wb = 6.1%, and the thickness change rate Tb = 1.5% may be set as threshold values, and these threshold values may be set at the same time. You don't have to be satisfied with everything. Then, 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. As described above, the reason why any one of the length, the width, and the thickness should be satisfied is not clearly recognized in Table 4-2, but the area of the cross section perpendicular to the longitudinal direction is smaller. This is because when the heated aroma generating base material is dried, distortion occurs, and the heated aroma generating base material in which the foliage of a plant is dispersed as an aroma source material has anisotropy.

This correlation is shown in Table 5-2 showing the rate of change in shape of the test piece having a length of 12 mm, a width of 1.5 mm, and a thickness of 0.3 mm. The length change rate La'= 4.8% after 10 minutes drying, the width change rate Wa'= 5.0%, the thickness change rate Ta'= 1.2%, and the length of 15 minutes drying. At least one of the change rate Lb'= 5.8%, the width change rate Wb'= 5.1%, and the thickness change rate Tb'= 1.5% may be set as the threshold values. It is not necessary to satisfy all the thresholds at the same time. 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.

As described above, the base material for generating aroma to be heated of the present invention is made of a material having different properties such as an aromatic source material, an aerosol former, and a binder. The production method such as curing of the composition, the addition of crosslinked PVP and its addition method, and the addition of microcrystalline cellulose enable uniform mixing and dispersion of an aromatic source material, an aerosol former, a binder and the like. It is an object of the present invention to provide a high-quality material for generating an aroma to be heated, which realizes easy prevention of dissipation of an aerosol over time and prevention of shrinkage of a shape over time and shrinkage of a shape due to heating.

As a result, when the heated fragrance cartridge provided with the heated fragrance source composed of the heated fragrance generating base material of the present invention is attached to or detached from the heated smoking equipment, the heated fragrance generating source is deformed and the heated fragrance is generated. A heat-heated aroma-generating base material that solves problems such as falling and dropping of the base material, imparts the toughness and strength required for this molding process, and can fully enjoy the aroma volatilized from the heated aroma source material. Can be provided.

Further, in the base material for generating a fragrance to be heated of the present invention, when a refreshing agent such as menthol or xylitol is added as a fragrance, the dissipation of the fragrance or the cooling agent over time is suppressed, and the fragrance to be heated containing the fragrance is suppressed. Even after the heated fragrance cartridge provided with the source is stored for a long period of time, the fragrance of the heated fragrance generating base material can be fully enjoyed when it is attached to the heated smoking device and smoked.

Further, the heated fragrance generating base material of the present invention has little dimensional change due to drying, and even after a heated fragrance cartridge provided with a heated fragrance generating source containing the same is attached to a heated smoking device and smoked. The heated fragrance generating base material does not fall off or fall from the heated fragrance cartridge, and even after long-term storage, the heated fragrance generating base material does not fall off or fall from the heated fragrance cartridge, and is excellent in handleability. , It is possible to provide a heated aroma generating base material capable of preventing contamination of a heat source of a heated smoking device.

Another object of the present invention is to provide a heated fragrance source using such a heated fragrance generating base material and a heated fragrance cartridge provided with the heated fragrance generating source. The heated fragrance source and the heated fragrance cartridge of the present invention are not limited to these, and various modifications shall be made without departing from the gist of the present invention. Is possible and is limited only by the technical ideas described in the claims.

The member 333 is wound by the mouthpiece reinforcing member 3301 around the filter member 333 portion of the mouthpiece 330 composed of the support member 331 and the filter member 333 in a state where the member 333 is wound by the exterior member 310 of the fragrance to be heated cartridge. There is.

FIG. 2 shows an example of the heated fragrance cartridge 400 used in the above Examples and Comparative Examples, which is suitable for an omnidirectional heat source by electromagnetic induction heating. In the heated fragrance cartridge 400 according to the embodiment of the present invention, the heated fragrance generating source 420 in which the aggregate 421 of the heated fragrance generating base material of the present invention is wound around the heated fragrance generating base material wrapping member 422. A cooling member 432 attached to one end on the suction side in the longitudinal direction of the heated fragrance source 420, and a filter member 433 attached to one end on the suction side in the longitudinal direction of the cooling member 432. A hollow tube 434 attached to one end of the filter member 433 on the suction side in the longitudinal direction is wound by the heated fragrance cartridge exterior member 410.

However, the heated fragrance cartridge of the present invention is not limited to such a configuration, and can be configured in various configurations according to the smoker's preference regarding flavor, smoke, suction amount, cost, and the like. It has a special feature.

This various configurations will be described using the heated fragrance cartridge 300 suitable for the blade type heat source shown in FIG. 1, but the heated fragrance cartridge of the present invention is not limited to these, and is within the scope of claims. It is limited only by the described technical idea.

First, in the heated fragrance source 320 constituting the heated fragrance cartridge 300 of the present invention, as shown in FIG. 1, the aggregate 321 of the heated fragrance generating base material 3211 (FIG. 3) is the heated fragrance generating base material. It is characterized in that it is wound around a wrapping member 322. As is clear from the cross-sectional view perpendicular to the longitudinal direction of the heated aroma generating source in FIG. 3, the heated aroma generating base material aggregate 321 of the present invention is a prismatic heated aroma generating base material (single unit) 3211. , The heated aroma generating base material 3211 is composed of the primary aggregate 3212 of the heated aroma generating base material formed by irregular contact, and the inside of such a heated aroma generating base material aggregate 321 and the subject. Between the heated aroma generating base material aggregate 321 and the heated aroma generating base material wrapping member 322, a gas flow path 321A in the primary aggregate, a gas flow path 321B between the primary aggregates, and a gas flow between the base material alone / the primary aggregate. It is characterized in that the cross-sectional shape of the aroma generating base material 3211 to be heated and the arrangement state parallel to the longitudinal direction are such that the path 321C, the gas flow path 321D between the base material aggregate / wrapping member, and the like are easily formed. ..

However, the cross-sectional shape of the base material for generating aroma to be heated is preferably a quadrangle shown in FIG. 3 in order to achieve both productivity and gas flow path formation, but a polygonal or star-shaped polygon is preferable. More preferable from the viewpoint of road formation. Further, it is more preferable that the base material for generating aroma to be heated is hollow.

Further, it does not necessarily have to be prismatic, and may be in the form of a sheet. In this case, it is preferable that the gas flow path is formed irregularly in parallel with the longitudinal direction of the aroma generation source to be heated.

Further, as will be described later, the heated fragrance generating source does not necessarily require the heated fragrance generating base material wrapping member, and for example, directly on the exterior member corresponding to the heated fragrance cartridge exterior member 310 in FIG. It may be wrapped. In this case, the exterior member is preferably made of a material having strength for installing the fragrance to be heated cartridge.

Further, the fragrance wrapping member to be heated does not necessarily have to be paper. Plastic films are more suitable than paper because they do not come into contact with blade-type heat sources and require aerosol former resistance of the aroma generating substrate to be heated. In particular, from the viewpoint of environmental protection, it is preferable to use a biodegradable plastic film. Plastics include plastics such as polyolefins, polyesters and nylons and engineering plastics, and biodegradable plastics include poly (3-hydroxybutyrate) (PHB), poly (ε-caprolactone) (PCL) and poly (butylene). Succinate) (PBS), poly (L-lactide) (PLA) and the like can be mentioned. These materials can also be applied to the exterior member 310 of the aromatic cartridge to be heated, the support member 331, the cooling member 332, the filter wrapping member 3331 of the filter member 333, and the hollow tube 334, which will be described later. It needs to be molded into a shape that exhibits functions according to the application.

The heated fragrance cartridge 300 of FIG. 1 according to an embodiment of the present invention includes a heated fragrance source 320 and a support member 331 attached to one end of the heated fragrance source 320 on the suction side in the longitudinal direction. , The support member 331 is composed of a filter member 333 attached to one end on the suction side in the longitudinal direction, and is wound by the heat-heated fragrance cartridge exterior member 310, and further, the support member 331 and the filter member 333. A mouthpiece reinforcing member 3301 is wound around the filter member 333 portion of the mouthpiece 330. However, the mouthpiece reinforcing member 3301 is not always necessary, and at least an exterior member corresponding to the heated fragrance cartridge exterior member 310 may be provided. That is, except for the heat-heated aerosol generator, which is an essential component, the support member 331 mainly having a function of preventing the heat-heated aromatic source from moving to the suction side and the volatilized aerosol former shown in FIG. 4 are cooled. A cooling member 332 having a function of promoting the formation of an aerosol that becomes smoke, a filter member 333 having a function of filtering mainly volatile components generated from a fragrance source to be heated and components that become unpleasant taste from smoke, and mainly It suffices to have at least one selected from the hollow tube 334 having a function of being easily held in the mouth. Then, as shown in FIG. 4, the mouthpiece 330 is composed of at least one 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 deployed as mouthpieces, there is a rule that they are arranged on the suction side in the longitudinal direction from the source of the aroma to be heated, and the support member 331, the cooling member 332, the filter member 333, and the hollow It is preferable that the positional relationship of the pipe 334 is observed.

For example, in the heated fragrance cartridge 300 according to the embodiment of the present invention, as shown in FIG. 5, the heated fragrance generating base material aggregate 321 is wrapped with the heated fragrance generating base material wrapping member 322 to be heated. The fragrance source 320 is characterized in that it is fixed to one end of a heat-resistant fragrance cartridge exterior member 310 having water resistance and pressure resistance that can retain its shape even when it is held by the lips. It is one of the heated fragrance cartridges having a simple structure including only the heated fragrance source 320 and the heated fragrance cartridge exterior member 310. In this case, the heated fragrance cartridge exterior member 310 in the portion other than the heated fragrance source 320 is the hollow tube 334 that serves as the mouthpiece 330.

The simplest heated fragrance cartridge is one that is not provided with the heated fragrance generating base material wrapping member 322 of the heated fragrance generating source 320 in FIG. 5, but is wrapped with the heated fragrance generating base material wrapping member 322. The heated fragrance source 320 is preferable because it is easy to handle in manufacturing the heated fragrance cartridge.

Further, for example, in the heated fragrance cartridge 300 according to the embodiment of the present invention, as shown in FIG. 6, the heated fragrance generating base material aggregate 321 is wrapped with the heated fragrance generating base material wrapping member 322. A hollow tube 334 made of a water-resistant and pressure-resistant material that can retain its shape even when held by the lips is attached to one end of the heat-heated fragrance source 320 on the suction side in the longitudinal direction. It is characterized in that it is wound around a heated fragrance cartridge exterior member 310, and a hollow tube 334 serves as a mouthpiece 330.

That is, the hollow tube 334 can be replaced with at least one selected from the support member 331, the cooling member 332, and the filter member 333 shown in FIG. Further, at least one selected from the support member 331, the cooling member 332, and the filter member 333 shown in FIG. 4 can be added while leaving the hollow tube 334. When two or more of these are deployed as mouthpieces, there is a rule that they are arranged on the suction side in the longitudinal direction from the source of the aroma to be heated, and the support member 331, the cooling member 332, the filter member 333, and the hollow It is preferable that the positional relationship of the pipe 334 is observed.

When the fragrance to be heated cartridge is constructed in this way, the support member 331, the cooling member 332, the filter member 333, and the hollow tube 334 used as the mouthpiece 330 are provided according to their materials and structures. It can be wrapped with individual wrapping members and, together with the heated fragrance source 320, by the heated fragrance cartridge exterior member 310. Further, after the support member 331, the cooling member 332, the filter member 333, and the hollow tube 334 used as the mouthpiece 330 are collectively wrapped with the wrapping member, they are heated together with the heated aroma generation source 320. It can also be wound by the fragrance cartridge exterior member 310. However, the method of arranging the fragrance to be heated cartridge is not limited to these.

FIG. 7 shows a heated fragrance cartridge according to an embodiment of the present invention, which includes a mouthpiece reinforcing member 3301, a support member 331, a cooling member 332, a filter member 333, and a hollow tube 334 as the mouthpiece 330. 300 is shown.

The fragrance to be heated cartridge is characterized in that the filter member 333 and the hollow tube 334 of the piece 330 are reinforced by the mouthpiece reinforcing member 3301.

The heated fragrance cartridge 300 shown in FIG. 7 is not limited to this configuration, and the support member 331, the cooling member 332, and the hollow tube 334 may be wound with wrapping members suitable for each. The heated fragrance generating source 320 and the filter member 333 may not be wound with the heated fragrance generating base material wrapping member 322 and the filter wrapping member 3331, respectively. Further, after the support member 331, the cooling member 332, the filter member 333, and the hollow tube 334 are collectively wrapped with the mouthpiece wrapping member, one end of the support member 331 and one end of the heated aroma generation source 320 After being brought into contact with each other, all of them may be wrapped with the heated fragrance cartridge wrapping member 310. In addition, various heated fragrance cartridges can be manufactured by selecting and arranging various members.

The heated fragrance cartridge 300 of the present invention has been described above by taking up the heated fragrance cartridge 300 used by being attached to a heated smoking device provided with a blade-type heat source by a heater, but these are based on electromagnetic induction heating. This is a technique applicable to the heated fragrance cartridge 400 used by being attached to a heated smoking device equipped with an omnidirectional heat source. However, in the heated fragrance cartridge 400 used by being attached to a heated smoking device equipped with an omnidirectional heat source, the entire heated fragrance source 320 is heated to about 240 ° C., so that the heated fragrance generating base material is used. Plastics, engineered plastics, biodegradable plastics, and the like cannot be applied as paper substitute materials for the wrapping member and the exterior member of the aromatic cartridge to be heated. It is necessary to apply a special engineering plastic having a heat resistance equivalent to that of cellulose fibers (constituting paper) in which glass transition or thermal decomposition is started at about 300 ° C., that is, a glass transition temperature of 240 ° C. or higher. Examples of such special engineering plastics include polyamide-imide, polyarylate, polyimide, polytriazine, and liquid crystal polymer.

However, plastic, engineered plastic, and biodegradable plastic may be applied to the support member, cooling member, filter wrapping member of the filter member, hollow tube, etc., to which the heat of the omnidirectional heat source is not transferred. From the viewpoint of environmental protection, it is preferable to use biodegradable plastic. However, it needs to be molded into a shape that exhibits functions according to each application.
