Description

[Technical field]

[0001] The present invention relates to a heated aroma cartridge which connects a heated aroma generating source which is an assembly of heated aroma generating base materials containing an aerosol former, aroma source, binder, etc., which is attached to a heated aroma device equipped with a heat source such as an electronically controlled heater and heated to generate aerosol and aroma, and a mouthpiece which is equipped in the longitudinal direction with at least one of a support member, a cooling member and a filter, and which relates to a support member having the functions required by the mouthpiece, and provides a heated aroma cartridge equipped with that support member.

[0002] In particular, the present invention relates to a support member that has, among the functions required of a mouthpiece, the function of stably supporting the heated aroma-generating substrate and the heated aroma-generating source when the heated aroma cartridge is attached to a heated aroma device and when smoking, the function of cooling the volatile components of the aerosol former and aroma raw material generated from the heated aroma-generating substrate when heated, and the function of allowing these volatile components to pass through without resistance, and it is possible to provide a heated aroma cartridge equipped with this support member.

[0003] Conventionally, the above-mentioned "heated aroma-generating substrate" has been called "aerosol-forming substrate". However, by heating, the aroma components of the aroma raw material and the aromatic agent are volatilized together with the aerosol former that generates the aerosol, and the aerosol smoke and the aroma of the aroma raw material and the aromatic agent are enjoyed by smoking, so in the present invention, it is called "heated aroma-generating substrate". Based on this, the conventional names of "aerosol-forming body" (aggregate of aerosol-forming substrates), "electronic cigarette cartridge", and "heated smoking device" are called "heated aroma-generating source", "heated aroma cartridge", and "heated aroma device", respectively. [Background technology]

[0004] In recent years, as smoking bans have become more widespread in public spaces such as workplaces and restaurants, the number of smokers who use flame-based smoking, which burns tobacco, is decreasing, while the number of smokers who use heated smoking, which uses heated aroma cartridges that are equipped with a heated aroma generation source, which is an assembly of heated aroma-generating substrates containing an aerosol former that generates an aerosol, and an aroma source including tobacco plants of the genus Nicotiana, family Solanaceae, and that are heated by heat transferred from a heat source such as a heater, is rapidly increasing.

[0005] In the case of traditional flame smoking, the number of enthusiasts was extremely large because the burning of tobacco produces smoke that satisfies the smoker's visual desire, nicotine that is the root cause of the smoker's addiction to tobacco, and a large number of aromatic substances. However, a temperature of at least 600°C is required for combustion, and it can reach a maximum of 900°C when smoking, and the amount of harmful substances produced by flame smoking is extremely large, so in today's health-conscious world, there is a very clear tendency for enthusiasts to shy away from flame smoking, not only from non-smokers who are concerned about passive smoking, but also from enthusiasts themselves.

[0006] In contrast, heated smoking allows smoking at temperatures of about 200 to 350°C, which is the temperature at which tobacco leaves begin to decompose thermally, and contains aromatic materials other than tobacco leaves, so not only can it prevent the generation of harmful substances due to combustion, but it also reduces the generation of harmful substances due to thermal decomposition. For this reason, various technological developments that make heated smoking even more enjoyable are being actively carried out (e.g., Patent Documents 1 to 11).

[0007] The mechanism of such heated smoking varies depending on the form of the heated smoking device, heated aroma cartridge, etc., but will be explained using a typical example in which a heated aroma cartridge is attached to a heated aroma device that uses a heater blade as a heat source and smoking is performed.

[0008] The heated aroma cartridge is configured by connecting a heated aroma generating source and a mouthpiece in this order in the longitudinal direction from the heat source. This mouthpiece is at least one selected from a support member, a cooling member, and a filter, but when multiple members are used, it is common to form the mouthpiece by connecting a support member, a cooling member, and a filter in this order in the longitudinal direction from the heat source (Patent Documents 1 to 11).

[0009] The heated aroma-generating substrate is a mass of an aerosol former, such as glycerin or propylene glycol, an organic solvent with a boiling point of about 150 to 300°C, various non-tobacco plants including tobacco plants having aroma components, and aroma agents, which are formed with a binder such as polysaccharides. When smoking, the aroma cartridge is mounted in a chamber of a heating aroma device equipped with a heating element, and the heating element is inserted into the heated aroma-generating source. The heated cartridge is then heated to about 200 to 350°C by an electronically controlled heating source, generating volatiles (vapor) of the aerosol former, as well as volatiles of various non-tobacco plants including tobacco plants and aroma components of the aroma agents.

[0010] The support member, cooling member, and filter that constitute the mouthpiece each have the following functions (Patent Documents 7 to 11).

[0011] The support member supports the heated aroma-generating substrate and the heated aroma-generating source when the aroma cartridge is attached to the heated aroma device, and also plays the main role of preventing damage to the heated aroma-generating substrate and the heated aroma-generating source or movement toward the mouthpiece when the substrate is attached or when smoking.It also serves as a flow path for volatile matter produced when the heated aroma-generating substrate is heated, and also acts as a cooling member which has a significant influence on the generation of smoke (core) as the volatile matter passes through the support member (Patent Document 11).

[0012] The cooling member is a flow path for actively cooling the volatile substances produced when the heated aroma-generating substrate is heated, and is often formed from a porous material with a large contact area with the volatile substances, which is thought to have a greater cooling effect than the support member (Patent Documents 7, 9, 10, and 11), but may also act as a filter capable of adsorbing harmful substances (Patent Document 9).

[0013] The filters used are similar to those used in cigarettes, made from bundles of cellulose acetate fibers that can filter out volatile matter and harmful substances contained in smoke, or made from carbon materials with pore structures that have excellent substance adsorption capabilities (Patent Documents 7 to 11).

[0014] Thus, to summarize the mechanism of heated smoking, the smoke generated when the volatile matter in the aerosol former passes through a support member and a cooling member and is cooled, and smoking is enjoyed by inhaling the aromatic components volatilized from various non-tobacco plants, including tobacco plants, and aromatic agents.

[0015] In particular, the phenomenon in which the volatile matter of the aerosol former cools to generate smoke is a phenomenon in which droplets are formed from vapor, and it is interesting that this is one of the nucleation phenomena in which a local thermodynamic phase change occurs. This nucleation phenomenon has important significance in the mechanisms of the formation of water droplets that adhere to cups and windowpanes in daily life, clouds and rainfall, the mechanisms of aerosol formation in the atmosphere related to environmental science, processes using steam in factories and hospitals, and crystals formed from solutions, and has been the subject of various theoretical and experimental research since ancient times (Non-Patent Documents 1-8). Therefore, the development of smoking by attaching a heated aroma cartridge to a heating aroma device utilizes the nucleation phenomenon and can be carried out based on the results of theoretical and experimental research to date.

[0016] The mouthpiece is closely related to this nucleation phenomenon, and serves as a passage through which the vapor, which is a volatile matter of the aerosol former, passes. In particular, the support member and the cooling member are the place where smoke is generated by the nucleation phenomenon, and are also the passage through which the vapor passes, so the smoke generation mechanism in the support member and the cooling member must be considered in conjunction with the nucleation phenomenon and a phenomenon based on fluid mechanics (Non-Patent Documents 8 to 11).

[0017] Since the mechanism of smoke generation in the support member and the cooling member has a significant effect on the design of the support member and the cooling member, the nucleation phenomenon and the flow state of the volatile matter of the aerosol former in the support member and the cooling member are considered.

[0018] First, when considering smoke (nuclei) generation by cooling volatile matter in an aerosol former, i.e., aerosol generation, from the perspective of conventional nucleation mechanisms based on thermodynamics, two types of generation can be considered: (1) homogeneous condensation nucleation in the gas phase, and (2) heterogeneous condensation nucleation on a wall surface (Non-Patent Documents 1, 4, and 7).

[0019] In addition, although the nucleation mechanism differs depending on the wettability of the wall surface, it is believed that nucleation occurs in two stages: (2) primary nucleation by heterogeneous condensation nucleation on the wall surface, and (1) secondary nucleation, which is homogeneous condensation nucleation in the gas phase.

[0020] In particular, the homogeneous condensation nuclei of secondary nucleation are smaller than the heterogeneous condensation nuclei of primary nucleation, and the number of secondary nuclei is greater than the number of primary nuclei, which is presumably closely related to the amount and size of smoke generated by the aroma cartridge. The number of secondary nuclei increases as the cooling rate increases and as the steam flow becomes more turbulent, and the average particle size of the nuclei decreases accordingly, which has a significant effect on the amount and size of smoke generated by the aroma cartridge.

[0021] On the other hand, primary nucleation is more likely to occur as the vapor has a higher wettability with the wall surface, and is considered to be influenced by the materials of the support member and cooling member that form the flow path of the aroma cartridge.

[0022] Next, as for phenomena based on fluid mechanics, as is clear from the equation of continuity, Bernoulli's theorem, Reynolds number, etc., the flow rate, flow manner, and cooling rate of the volatiles of the heated aroma-generating substrate, which is a fluid, are strongly influenced by the structures of the support members and cooling members that form the flow path. For example, the shape of the flow path greatly affects the flow rate and flow manner of the volatiles, and it is believed that volatiles flowing through thin tubes have high flow rates and cooling rates and are prone to turbulence, making them more susceptible to nucleation phenomena (Non-Patent Documents 8 to 11).

[0023] In this way, when the mechanism of smoke generation in heated smoking is examined from the perspective of the thermodynamic element of the nucleation phenomenon and the fluid dynamic element indicating the state of the fluid, it can be seen that the structure and material of the support member and cooling member that affect the generation of smoke have a significant impact on the generation of smoke.

[0024] However, the mouthpieces of the prior art, particularly the support member and cooling member, are not designed based on thermodynamics, which is that smoke is generated by a nucleation phenomenon, and on fluid dynamics, which is that they are gas flow paths, and therefore have a complex structure, and no mouthpieces have been provided that enable smoking in accordance with the smoker's preferences and operation (Non-Patent Documents 8 to 10).

[0025] As a result, it was necessary to separately arrange in the heated aroma cartridge a support member having the function of preventing damage or movement of the heated aroma-generating substrate and the heated aroma-generating source when the heated aroma cartridge is attached to a heated aroma device and when smoking, and a cooling member that generates an aerosol from the volatiles of the aerosol former (Non-Patent Documents 8-10).

[0028] In a heated aroma cartridge in which a heated aroma generating source, which is an aggregate of heated aroma generating substrates that generate volatiles that become components of an aerosol and aroma, is arranged on the upstream side, and a mouthpiece equipped with at least a support member is arranged on the downstream side and connected in the longitudinal direction, the support member and cooling member that constitute the conventional mouthpiece are not designed based on thermodynamics that smoke is generated by a nucleation phenomenon and fluid dynamics that it is a gas flow path, so that the structure is complicated and no one that enables smoking suited to the smoker's preferences and operation has been provided. As a result, it was necessary to separately arrange in the heated aroma cartridge a support member that prevents damage or movement of the heated aroma generating substrate and the heated aroma generating source when the heated aroma cartridge is attached to a heating type aroma device and when smoking, and a cooling member that generates an aerosol from the volatiles of the aerosol former. [Means for solving the problem]

[0029] Therefore, the inventors reexamined the mouthpiece that constitutes the aroma cartridge from the viewpoint that the generation of smoke from such a heated tobacco is a nucleation phenomenon in which droplets are formed from steam, and is influenced by the hydrodynamic phenomenon of the steam flowing through the flow paths of the support member and the cooling member.As a result, they found that there exists a support member having a flow path of an appropriate structure that can prevent damage or movement of the heated aroma-generating substrate and the heated aroma-generating source, and enable smokers to enjoy pleasant smoke and aroma, which led to the completion of the present invention.

[0030] The present invention relates to a heated aroma cartridge which is connected in the longitudinal direction, with a heated aroma generating source which is an aggregate of heated aroma generating substrates which are heated to produce volatiles that become aerosol and aroma components on the upstream side and a mouthpiece equipped with at least a support member on the downstream side, based on the direction of airflow when a smoker inhales through the heated aroma cartridge. The support member is characterized in that it at least has a support section which prevents damage or movement of the heated aroma generating substrates and the heated aroma generating source, and a flow path which passes through and cools the volatiles, and the cross-sectional shape, area, number and porosity of the inlet through which the volatiles flow into the flow path and the outlet through which the volatiles flow out of the flow path, taken perpendicular to the longitudinal direction of the heated aroma cartridge, as well as the contact surface area of ​​the flow path with the volatiles, are thermodynamically and fluid-dynamically devised. The present invention also relates to a heated aroma cartridge equipped with such a support member.

[0031] The first feature of the present invention is that it comprises a support part which prevents damage or movement of the heated aroma generating substrate and the heated aroma generating source, and a flow path through which volatiles pass and are cooled, and when the cross-sectional area and surface properties of the flow path are the same, the shape of a cross section perpendicular to the longitudinal direction of the heated aroma cartridge at the inlet where the volatiles flow into the flow path is different from the shape of a cross section perpendicular to the longitudinal direction of the heated aroma cartridge at the outlet where the volatiles flow out of the flow path, however, it is not limited to the cross-sectional shape of the flow path, the position at which the flow paths are arranged, the number of flow paths, etc.

[0032] As shown in Table 1, for easy comparison, for example, when considering circular, square, and equilateral triangular flow paths and calculating the cross-sectional area and surface area, the surface area (inner wall surface area) of the flow path per mm of the length of the support member increases in the order of circle, square, and triangle, even for flow paths with the same cross-sectional area. Based on the aerosol generation mechanism, this means that it affects the cooling speed of the volatile matter in the aerosol former, and aerosols with different properties, i.e., smoke with different properties, are generated. Note that the porosity is defined here as the ratio of the cross-sectional area perpendicular to the longitudinal direction of the heated aroma cartridge formed by the outer periphery of the flow path to the cross-sectional area perpendicular to the longitudinal direction of the heated aroma cartridge formed by the outer periphery of the support member.

[0033] [Table 1]

[0034] The aerosol generation mechanism of the volatile matter of the aerosol former is considered to occur through two stages of nucleation: primary nucleation by wall-surface heterogeneous condensation nucleation, and secondary nucleation, which is homogeneous condensation nucleation in the gas phase. The homogeneous condensation nuclei of the secondary nucleation are smaller than the heterogeneous condensation nuclei of the primary nucleation, and the number of secondary nucleations is greater than the number of primary nucleations, which is closely related to the amount and size of smoke generated by the aroma cartridge. The number of secondary nucleations decreases with an increase in the cooling rate. Therefore, by making the shape of the inlet through which the volatile matter flows into the support member and the outlet through which the volatile matter flows out of the support member different, the smoke and aroma that the smoker tastes can be controlled, and even if the same heated aroma generating source is used, heated aroma cartridges with different smoke and aromas can be provided, allowing the smoker to enjoy a variety of smoking experiences.

[0035] Specifically, if the surface area of ​​the flow passage on the inlet side is designed to be large with the same cross-sectional area, a large amount of smoke with a small average particle size is generated, and the smoke and aroma can be felt strongly. Conversely, if the surface area of ​​the flow passage on the inlet side is designed to be small with the same cross-sectional area, the opposite phenomenon occurs. Since these depend on the smoker's preferences, it is advantageous for a heated aroma cartridge provider to provide heated cartridges with various flavors while using the same heated aroma source. Here, the reason why the properties of smoke are closely related to aroma is based on the fact that smoke is a liquid generated by condensing volatile matter of a liquid called an aerosol former. This is because the average particle size and the number of particles generated on the smoke surface and inside the smoke have a large effect on the specific surface area. This is because the smaller the average particle size of the smoke, the more rapidly its specific surface area increases, and the more aromatic components adsorbed on the smoke surface, and the greater the number of particles generated, the more smoke containing aromatic components increases.

[0036] The second feature of the present invention is that it comprises a support part which prevents damage or movement of the heated aroma generating substrate and the heated aroma generating source, and a flow path through which volatiles pass and are cooled, and when the surface properties of the flow path are the same, the cross-sectional area perpendicular to the longitudinal direction of the heated aroma cartridge of the inlet through which the volatiles flow into the flow path is different from the cross-sectional area perpendicular to the longitudinal direction of the heated aroma cartridge of the outlet through which the volatiles flow out of the flow path. However, there is no limitation to the cross-sectional shape of the flow path, the position at which the flow paths are arranged, the number of flow paths, etc.

[0037] As is clear from the Bernoulli's theorem and the Reynolds number of fluid mechanics, the cross-sectional area of ​​the flow passage has a large effect on the properties of the flow. In particular, the smaller the cross-sectional area, the higher the flow rate, the higher the Reynolds number, and the more turbulent the flow will be. On the other hand, based on the aerosol generation mechanism, it is considered that the generation of aerosol, i.e., smoke, occurs through two stages of nucleation: primary nucleation by wall-like heterogeneous condensation nucleation, and secondary nucleation, which is homogeneous condensation nucleation in the gas phase. The homogeneous condensation nuclei of the secondary nucleation are smaller than the heterogeneous condensation nuclei of the primary nucleation, and the number of secondary nucleations is greater than the number of primary nucleations, which is closely related to the amount and size of smoke generated by the aroma cartridge. And, the number of secondary nucleations increases as the turbulence increases.

[0038] Specifically, the smaller the cross-sectional area of ​​the inlet flow passage is designed to be, the faster the flow rate and the more likely it is to become turbulent, so a large amount of smoke with a small average particle size is generated, and the smoke and aroma can be felt strongly. On the other hand, if the area of ​​the inlet side flow passage is designed to be large, the opposite phenomenon occurs. Since these depend on the smoker's preferences, it is an advantage for the heated aroma cartridge provider to provide heated cartridges with various flavors while using the same heated aroma generation source.

[0039] On the other hand, when the cross-sectional area of ​​the inlet flow path is designed to be small, the cross-sectional area of ​​the support part that prevents damage and movement, etc. of the heated aroma generating substrate and the heated aroma generating source increases, and therefore it is possible to prevent damage and movement, etc. of the heated aroma generating substrate and the heated aroma generating source when the heated aroma cartridge is attached to a heating type aroma device equipped with a blade-type heat source, etc. Furthermore, when a smoker inhales while smoking, the stress that the heated aroma generating source receives from the support member is reduced, and it is possible to prevent damage and movement, etc. of the heated aroma generating source.

[0040] The third feature of the present invention is that it comprises a support part which prevents damage or movement of the heated aroma generating substrate and the heated aroma generating source, and a flow path through which volatiles pass and are cooled, and when the surface properties of the flow path are the same, the cross-sectional shape and area perpendicular to the longitudinal direction of the heated aroma cartridge at the inlet where the volatiles flow into the flow path are different from the cross-sectional shape and area perpendicular to the longitudinal direction of the heated aroma cartridge at the outlet where the volatiles flow out of the flow path.

[0041] Such an inlet and an outlet can realize the synergistic effect of the first feature and the second feature, and make these effects more prominent. Specifically, when the cross-sectional shape of the flow path is designed so that the surface area of ​​the flow path is large and the cross-sectional area is small, the contact area with the volatile matter of the aerosol former increases, the cooling speed increases, and turbulence is easily generated, the flow rate increases, and the amount of smoke with a small average particle size increases significantly, and the smoke and aroma can be felt strongly. On the other hand, when the cross-sectional shape of the flow path is designed so that the surface area of ​​the flow path is small and the cross-sectional area is large, the opposite phenomenon occurs. Since these smokes and aromas depend on the tastes of the smoker, it is advantageous for the heated aroma cartridge provider to provide heated cartridges with various flavors, even though they are the same heated aroma generating source.

[0042] In this case, the location of the flow path is not particularly limited, but the shape and area of ​​the flow path need to be designed under the relative constraints of the inlet and outlet in order to realize the above-mentioned synergistic effect.

[0043] The fourth feature of the present invention is that it comprises a support part which prevents damage or movement of the heated aroma-generating substrate and the heated aroma-generating source, and a flow path through which volatiles pass and are cooled, and when the surface properties of the flow path are the same, the number of inlets through which the volatiles flow into the flow path is different from the number of outlets through which the volatiles flow out of the flow path.

[0044] In the case of a heated aroma cartridge using a support member having the first feature of the present invention, by increasing or decreasing the number of flow paths, it is possible to control the smoke properties and at the same time control the flow rate under a certain suction force. That is, depending on the number of flow paths, smoke and aroma can be enjoyed without feeling resistance to suction when smoking. However, in the second and third features of the present invention, even if the number of flow paths is increased or decreased, a difference in porosity must be provided in the flow paths in order to effectively control the smoke properties, so a design that controls the resistance to suction when smoking is necessary.

[0045] However, according to the fourth feature of the present invention, it is possible to equalize the total cross-sectional area of ​​the inlet and outlet, and at the same time, it is possible to control the smoke properties depending on the size of each cross-sectional area, and at the same time, to control the flow rate under a constant suction force. In other words, by controlling the number and cross-sectional area of ​​the flow paths, it is possible to enjoy the smoke and aroma without feeling any resistance to inhalation when smoking.

[0046] In this case, there are no limitations on the cross-sectional shape and cross-sectional area of ​​the flow passage, the position where the flow passage is arranged, the number of the flow passages, etc. However, it is necessary to appropriately design the total cross-sectional area of ​​the flow passage so that the flow rate is appropriate according to the suction force of the smoker.

[0047] The fifth feature of the present invention is that it comprises a support part which prevents damage or movement of the heated aroma generating substrate and the heated aroma generating source, and a flow path which allows volatiles to pass through and cool them, and the porosity, defined as the ratio of the cross-sectional area perpendicular to the longitudinal direction of the heated aroma cartridge formed by the outer periphery of the flow path to the cross-sectional area perpendicular to the longitudinal direction of the heated aroma cartridge formed by the outer periphery of the support part, is designed to be approximately 1 to 70%.

[0048] With this configuration, a support part is formed with an area capable of supporting the heated aroma generating source, which is an aggregate of heated aroma generating substrates, on a surface thereof, and therefore it is possible to prevent damage and movement, etc. of the heated aroma generating substrate and the heated aroma generating source when the heated aroma cartridge is attached to a heating type aroma device equipped with a blade-type heat source, etc. Furthermore, even when a smoker inhales while smoking, the stress that the heated aroma generating source receives from the support member is reduced, and it is possible to prevent damage and movement, etc. of the heated aroma generating source.

[0049] The cause of the breakage and movement of such heated aroma generating substrates and heated aroma generating sources is due to the material composition for realizing the mechanism of heated smoking, in which the heated aroma generating substrate constituting the heated aroma generating source is molded from a composition including an aerosol former, tobacco plants and various plants that volatilize aroma components when heated, aromatics, and binders such as polysaccharides and cellulose fibers for binding them. The heated aroma generating substrates molded from such compositions, such as rectangular columns, cylinders, and granules, are brittle lumps that are somewhat viscous and plastically deformable, and therefore break under slight stress. In addition, the heated aroma generating source is usually molded by wrapping the heated aroma generating substrate with a heated aroma generating substrate wrapping member, but if the heated aroma generating substrate with such physical properties is tightly wrapped, there is a problem that the heated aroma generating substrate is destroyed and the flow path of the volatile matter when heated is blocked, and the wrapping state with a gap secured is also a cause of the breakage and movement described above.

[0050] Therefore, if the porosity is about 70% or more, the cross-sectional area of ​​the support part is reduced, making it difficult to support the heated aroma generating substrate and the heated aroma generating source on a surface, and making it difficult to prevent damage and movement of these when the heated aroma cartridge is attached and when smoking.Therefore, it is more preferable that the porosity is about 50% or less.

[0051] On the other hand, if the porosity is less than about 1%, resistance to inhalation during smoking will be large, so the porosity is more preferably about 2% or more, and even more preferably about 5% or more.

[0052] The sixth feature of the present invention is that it is provided with a support part that prevents damage or movement of the heated aroma-generating substrate and the heated aroma-generating source, and a flow path that passes volatiles and cools them, and the difference between the porosity of the inlet and the porosity of the outlet is designed to be approximately 19 to 69%.

[0053] The flow path of the support member of the present invention was devised based on the smoke generation mechanism by condensation of volatiles in the aerosol former and the state of the flow of the volatiles, and in order to effectively control the properties of the smoke, it is preferable to design the difference between the porosity of the inlet and the porosity of the outlet to be about 19 to 69%, and more preferably about 19 to 49%. If it is outside this range, the difference in the cooling speed and flow rate of the volatiles flowing through the flow paths of different structures will be small, making it difficult to generate smoke with different properties.

[0054] Thus, the flow path is greatly influenced by the cross-sectional shape, cross-sectional area, and number, etc., but the porosity is an important factor in considering the balance between the support part that prevents the heated aroma-generating substrate and the heated aroma-generating source from being damaged or moved, and the flow path that passes through the volatiles and cools them, so the cross-sectional shape of the flow path and the position where the flow path is arranged are not particularly limited. Therefore, the cross-sectional shape can be various shapes such as a circle, a semicircle, an ellipse, a triangle, a square, a polygon, and a star. In addition, the position where the flow path is formed may be within or on the outer periphery of the support member, and is preferably in a symmetrical positional relationship with the center of the support member. However, it may be in an irregular positional relationship.

[0055] The seventh feature of the present invention is that it comprises a support part which prevents the heated aroma-generating substrate and the heated aroma-generating source from being damaged or moved, and a flow path which passes volatile matter and cools it, and the inner wall surface area of ​​the flow path is designed to be 18 to 500 mm2 per mm of the length of the support member.

[0056] Smoke, one of the important elements in conventional heated smoking, is generated in a mouthpiece, which acts as a flow path for the vapor, which is a volatile product of the aerosol former, and various configurations of the mouthpiece have been considered, and the mouthpiece is equipped with a support member, a cooling member, and a filter. The support member and cooling member, which act as the flow path for the volatile products of the aerosol former generated from the heated aroma-generating substrate, play an important role as the site for generating smoke through the nucleation phenomenon known as condensation.

[0057] Here, the conventional support member prevents the movement of the heated aroma generating substrate and the heated aroma generating source, and the cooling member with a large specific surface area is used to generate smoke, and a mouthpiece with a complex structure equipped with both has been designed. A representative example of the cooling member is a hollow cylindrical member with a sufficient flow path. On the other hand, the cooling member has been used with a complex uneven flow path or a collection of many thin flow paths to increase the contact area with the volatile matter.

[0058] Therefore, the cross-sectional area of ​​the support part of the support member that receives the heated aroma generating substrate and the heated aroma generating source is small, and the volatile matter flows easily, but it is difficult to prevent the heated aroma generating substrate and the heated aroma generating source from being damaged or moved when the heated aroma cartridge is attached or when smoking. On the other hand, the cooling member has a large contact area with the volatile matter and generates a lot of smoke, but unlike a filter similar to that of a cigarette made of a bundle of cellulose acetate fibers or a pore structure with excellent substance adsorption ability, the smoke adheres to the cooling member together with harmful substances, and the amount of smoke generated is insufficient. In addition, providing the support member and the cooling member complicates the structure of the mouthpiece.

[0059] However, the support member of the present invention is provided with a support section that prevents the heated aroma-generating substrate and the heated aroma-generating source from being damaged or displaced, and a flow path through which the volatiles pass and cool, and based on the structure of the flow path, ensures the cross-sectional area of ​​the support section that receives the heated aroma-generating substrate and the heated aroma-generating source, while producing rich smoke and aroma, and serves as both a conventional support member and a cooling member, and has been devised based on a completely new idea. Therefore, although the flow path of the present invention may have complex irregularities on the surface that comes into contact with the volatiles, the flow path has a relatively flat surface property, and the inner wall surface area of ​​the flow path is preferably 18 to 500 mm2 per mm of the length of the support member, more preferably 18 to 300 mm2, and even more preferably 18 to 250 mm2.

[0060] The eighth feature of the present invention is that the device comprises a support member for preventing damage or movement of the heated aroma-generating substrate and the heated aroma-generating source, and a flow path for passing volatile matter and cooling the same, the support member being molded from a hydrophilic polymer containing hydroxyl, carboxyl, amino, amide and ether groups. Also, only the inner wall of the flow path may be given such hydrophilicity.

[0061] As mentioned above, the aerosol generation mechanism is considered to occur through two stages of nucleation: primary nucleation by heterogeneous condensation nucleation on the wall surface, and secondary nucleation by homogeneous condensation nucleation in the gas phase. It has been confirmed that primary nucleation occurs more easily when the wettability of the vapor with the wall surface is high. This results in the generation of aerosols with a large average particle size.

[0062] Therefore, the material of the support member is preferably a hydrophilic polymer containing a hydroxyl group, a carboxyl group, an amino group, an amide group, and an ether group. Representative examples of such hydrophilic polymers include ethylene-vinyl alcohol copolymers, acrylic acid copolymers, methacrylic acid copolymers, maleic acid copolymers, acrylamide copolymers, quaternary ammonium salt type copolymers, various nylons, various polyethers, etc.

[0063] As described above, with the support member of the present invention, smoke with different average particle sizes and numbers generated is generated based on the differences in the shape, cross-sectional area, number, and porosity of the flow paths at the inlet and outlet, and is inhaled by the smoker in an uneven state with a time lag. However, when compared with the case where each is mixed and inhaled, it has been found that a more comfortable smoking experience can be achieved by, for example, forming a flow path with a large volume near the downstream end of the support member so that volatile matter flowing out from the flow path can accumulate.

[0064] Therefore, the ninth feature of the present invention is that it is provided with a support part that prevents damage or movement of the heated aroma-generating substrate and the heated aroma-generating source, and a flow path through which volatiles pass and are cooled, and is provided with a storage flow path that is connected to the front outlet end face of the support member and in which volatiles flowing out from the outlet are retained.

[0065] As described above, the support member of the present invention is capable of preventing damage or movement of the heated aroma generating substrate and the heated aroma generating source, while producing smoke and aromas that allow users to enjoy a variety of flavors, and is a support member that combines the functions of a conventional support member and a cooling member. Therefore, a heated aroma cartridge using this is less likely to contaminate the chamber of a heated smoking device, is easy to operate, and allows users to enjoy comfortable smoking. Moreover, by simply replacing the support member, users can enjoy smoking with different flavors using the same heated aroma generating substrate and heated aroma generating source. This not only increases the product variety of heated aroma cartridges, but also increases productivity.

[0066] Furthermore, in order to allow smokers to exchange various support members for enjoying smoke with various flavors, and to allow the heated aroma generating source and the mouthpiece to which the support member is attached to be detached, it is preferable to use a connecting member, for example, as the outermost outer material of the heated aroma generating base material. The material of such a connecting member is not particularly limited, but it is preferable that it is a cylindrical plastic that can be fitted with a screw or the like and can withstand attachment and detachment. For example, general-purpose resins such as polyolefin resins, polyester resins, nylon resins, EVA resins, and acrylic resins are preferably used, but biodegradable plastics are preferable from the viewpoint of protecting the natural environment. It is more preferable that it is .

[0067] In this way, the support member of the present invention has functions equal to or greater than those of conventional support members and cooling members, and can simplify the structure of the heated aroma cartridge, providing a heated aroma cartridge that is easy to handle and allows for enjoyable smoking. Effect of the Invention

[0068] The support member of the present invention comprises a support section for preventing damage or movement of the heated aroma-generating substrate and the heated aroma-generating source, and a flow path through which volatiles pass, and the inlet and outlet of the support member are provided with flow paths having different cross-sectional shapes, cross-sectional areas, porosities, and numbers, as well as flow paths having different surface areas of the inner walls of the upstream and downstream sides of the support member, so that a support section having an area capable of receiving the heated aroma-generating substrate and the heated aroma-generating source without damage or movement can be formed. At the same time, as a result of thermodynamic and fluid dynamic phenomena, smoke with different average particle diameters is generated in the upstream and downstream flow paths, allowing for the enjoyment of comfortable smoking. By utilizing this, a wide variety of smoke sensations and flavors can be enjoyed with a single type of heated aroma-generating source. Furthermore, the support member of the present invention combines the functions of a support member and a cooling member, and is simple in structure, and can be used in combination with the heated aroma-generating substrate and the heated aroma-generating source. It becomes possible to do so. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0070] The present invention will be described in more detail below using embodiments, but the present invention is not limited to these, and can be implemented in various modifications within the scope that does not deviate from the gist of the present invention, and is limited only by the technical ideas described in the claims.

[0071] The heated aroma-generating substrate and the heated aroma-generating source, which is an assembly of the heated aroma-generating substrate, used in the examples of the present invention were prepared as follows: Dried and ground saffron flowers, konjac, peppermint leaves, and apricot fruit were used as plants that volatilize aroma components, and these were mixed with cross-linked PVP, β-cyclodextrin, microcrystalline cellulose, and CMC-Na, which had been dissolved and mixed in a specified amount of pure water / ethanol, and then mixed with glycerin and propylene glycol, and further a potassium sorbate / sodium benzoate aqueous solution with konjac powder dispersed therein was added to prepare a heated aroma-generating substrate composition. Saffron flowers 87 parts by weight Apricot fruit 6 parts by weight Peppermint leaves 6 parts by weight Konjac 1 part by weight Glycerin 24 parts by weight Propylene glycol 24 parts by weight Crosslinked PVP 16 parts by mass β-Cyclodextrin 1 part by mass Microcrystalline cellulose 16 parts by weight CMC-Na 3 parts by mass Potassium sorbate 0.005 parts by mass Sodium benzoate 0.005 parts by mass

[0072] This composition was formed using three rolls to a sheet thickness of 0.28±0.02 mm. The sheet thus formed was then cut into pieces having a width of 1.5±0.1 mm to form heated aroma-generating substrate 310, which was then wrapped with heated aroma-generating substrate wrapping member 320 to achieve a predetermined filling rate. Next, this wrapped heated aroma-generating substrate 310 was cut to a length of 11.5-12.0 mm and then dried until the moisture content was 18-20% by mass, thereby producing heated aroma-generating source 300.

[0073] On the other hand, mouthpiece 400 constituting the heated aroma cartridge of the present invention is manufactured by connecting support member 510 and filter 700 formed from a bundle of cellulose acetate fibers in this order from the upstream side, and wrapping them with mouthpiece wrapping member 410, as shown in Figure 3.

[0074] The heated aroma generating source 300 and the mouthpiece 400 thus manufactured are connected to the mouthpiece 400 by a heated aroma cartridge wrapping member 410 as shown in FIG. 3, thereby manufacturing the heated aroma cartridge 200.

[0075] The heated aroma cartridge 200 having various support members manufactured in this manner arranged thereon was evaluated using IQOS (registered trademark) 100, a heated aroma device in which a blade-type heat source 130 is provided at the bottom of the chamber 120 of the main body 110, as shown in Figures 1 and 3.

[0076] In order to compare the support member of the present invention and the heated aroma cartridge 200 using it with the prior art, Figure 1 shows a heated aroma generating source 300, which is made up of a hollow cylindrical support member 500, a cooling member 600 made of an open-cell porous material with a porosity of 70% or more, and a filter 700 made of a bundle of cellulose acetate fibers, connected in this order to a prior art mouthpiece 400R, which is connected to a heated aroma cartridge 200R of the prior art, attached to a heated aroma device 100.

[0077] 1 is a cross-sectional view taken along the XY plane passing through the centre of the heated aroma cartridge 200R, and the first thing that can be seen from the figure is that the cross-sectional area taken along the YZ plane perpendicular to the longitudinal direction of the support part 502 of the support member 500 is only the circumferential part, and when the heated aroma cartridge 200R is attached to the heated aroma device 100 and when inhaling during smoking, the heated aroma generating substrate 310 and the heated aroma generating source 300 are subjected to a large amount of stress, resulting in problems such as breakage and movement. Secondly, the heated aroma generating substrate 310 is heated and generated, and the volatiles pass through the flow path 501 of the support member 500, but the inner wall area of ​​the flow path 501 is small, and the amount of smoke generated by the volatiles being cooled and condensed is extremely small, so that a cooling member 600 is required, and the structure of the heated aroma cartridge 200R becomes complicated.

[0078] FIG. 2 shows a first support member 510 according to one embodiment of the present invention, which is provided with a support part 512 for preventing damage or movement of the heated aroma-generating substrate 310 and the heated aroma-generating source 300, and a flow path within the outer periphery of the support member through which volatiles generated from the heated aroma-generating substrate 310 pass and are cooled, and in which the inlet through which volatiles flow into the flow path and the outlet through which volatiles flow out of the flow path have different cross-sectional shapes perpendicular to the longitudinal direction of the heated aroma cartridge 200 but have the same cross-sectional area: (a) First support member 510 FIG. 1 is a schematic cross-sectional view taken along the XY plane passing through the center of the device; (b) a side view seen from the left direction along the X axis; and (c) a side view seen from the right direction along the X axis.

[0079] As shown in Table 2, which shows the relative flow passage cross-sectional area (porosity) calculated when the cross-sectional area of ​​the support member is set to 100, the porosity is equal, but as can be seen from Table 1, the inner wall surface area of ​​the upstream flow passage with a triangular cross-sectional shape is larger than the inner wall surface area of ​​the downstream flow passage with a circular cross-sectional shape, and the cooling speed is faster, so the smoke on the upstream side has a small average particle size and is generated in large numbers, while the opposite phenomenon occurs on the downstream side. In particular, on the downstream side, smoke is generated on the upstream side, so the volatile matter concentration is lower and the number of smoke particles generated is smaller. Therefore, this support member generates smoke with a small average particle size and rich in aromatic components. If the support member is arranged in a reversed direction relative to the longitudinal direction, the opposite phenomenon to the above phenomenon occurs, and smoke with a different taste can be generated.

[0080] [Table 2]

[0081] Figure 3 is a schematic cross-sectional diagram taken along the XY plane passing through the center of the heated aroma cartridge, showing the state when a heated aroma cartridge 200 having the first support member 510 shown in Figure 2 arranged thereon is attached to a heated aroma device 100 during smoking, according to one embodiment of the present invention.

[0082] As is clear from the figure, by using such a support member 510, the cross-sectional area of ​​the heated aroma source support portion 512 is secured, and in particular, damage and movement of the heated aroma emitting substrate 310 and the heated aroma emitting source 300 can be reliably prevented when the heated aroma cartridge 200 is attached to the heated aroma device 100.

[0083] Figure 4 shows (a) a schematic cross-sectional view taken along the XY plane passing through the center of the second support member 520, (b) a side view seen from the left side of the X-axis, and (c) a side view seen from the right side of the X-axis of a second support member 520 according to one embodiment of the present invention, the second support member 520 having a support part 522 for preventing damage or movement of the heated aroma-generating substrate 310 and the heated aroma-generating source 300, and a flow path within the outer periphery of the support member through which volatiles generated from the heated heated aroma-generating substrate 310 pass and are cooled, the inlet through which volatiles flow into the flow path and the outlet through which volatiles flow out of the flow path having similar circular shapes in cross section perpendicular to the longitudinal direction of the heated aroma cartridge 200, the inlet having a smaller cross-sectional area than the outlet.

[0084] Figure 5 shows (a) a schematic cross-sectional view taken along the XY plane passing through the center of the third support member 530, (b) a side view seen from the left side of the X-axis, and (c) a side view seen from the right side of the X-axis of a third support member 530 according to one embodiment of the present invention, the third support member 530 having a support part 532 for preventing damage or movement of the heated aroma-generating substrate 310 and a flow path within the outer periphery of the support member through which volatiles generated from the heated aroma-generating substrate 310 pass and are cooled, and the inlet through which volatiles flow into the flow path and the outlet through which volatiles flow out of the flow path have similar triangular shapes in cross section perpendicular to the longitudinal direction of the heated aroma cartridge 200, the inlet having a smaller cross-sectional area than the outlet.

[0085] Figure 6 shows (a) a schematic cross-sectional view taken along the XY plane passing through the center of the fourth support member 540, (b) a side view seen from the left side of the X-axis, and (c) a side view seen from the right side of the X-axis of a fourth support member 540 according to one embodiment of the present invention, the fourth support member 540 having a support part 542 for preventing damage or movement of the heated aroma-generating substrate 310 and a flow path on the outer periphery of the support member through which volatiles generated from the heated aroma-generating substrate 310 pass and are cooled, the inlet through which volatiles flow into the flow path and the outlet through which volatiles flow out of the flow path have similar semicircular shapes in cross section perpendicular to the longitudinal direction of the heated aroma cartridge 200, and the inlet has a smaller cross-sectional area than the outlet.

[0086] Figure 7 shows (a) a schematic cross-sectional view taken along the XY plane passing through the center of the fifth support member 550, (b) a side view seen from the left side of the X-axis, and (c) a side view seen from the right side of the X-axis of a fifth support member 550 according to one embodiment of the present invention, the fifth support member 550 having a support part 552 for preventing damage or movement of the heated aroma-generating substrate 310 and the heated aroma-generating source 300, and a flow path on the outer periphery of the support member through which volatiles generated from the heated aroma-generating substrate 310 pass and are cooled, the inlet through which volatiles flow into the flow path and the outlet through which volatiles flow out of the flow path have similar triangular shapes in cross section perpendicular to the longitudinal direction of the heated aroma cartridge, the inlet having a smaller cross-sectional area than the outlet.

[0087] The shapes, numbers, and relative cross-sectional areas (porosity) of the inlet and outlet of the flow paths in Figs. 4 to 7 when the cross-sectional area of ​​the support member is taken as 100 are as shown in Table 2. In either case, the contact area of ​​the inner wall of the flow path per volatile matter increases on the upstream side, resulting in a high cooling rate and a high flow rate, which causes turbulence. This causes active secondary nucleation, which generates a large amount of smoke with a small average particle size, whereas the opposite phenomenon occurs on the downstream side. In particular, on the downstream side, smoke is generated on the upstream side, so the volatile matter concentration is low and the number of smoke particles generated is reduced. Therefore, these support members 520 to 550 generate smoke with a small average particle size and rich in aromatic components. If the support members are arranged in a reversed orientation relative to the longitudinal direction, the opposite phenomenon to the above phenomenon occurs, which allows smoke with a different taste to be generated.

[0088] Furthermore, as shown in Figures 4 to 7, when the porosity on the inlet side is small, the cross-sectional area of ​​the support parts 522 to 552 that receive the heated aroma emitting source 300 becomes large, which effectively prevents damage or movement of the heated aroma emitting substrate 310 and the heated aroma emitting source 300 when the heated aroma cartridge 200 is attached.

[0089] Figure 8 shows (a) a cross section taken along the XY plane passing through the center of the sixth support member 560, (a) of a sixth support member 560 according to one embodiment of the present invention, which is provided with a support part 562 for preventing damage or movement of the heated aroma-generating substrate 310 and the heated aroma-generating source 300, and a flow path within the outer periphery of the support member through which volatiles generated from the heated aroma-generating substrate 310 pass and are cooled, and in which the inlet through which the volatiles flow into the flow path and the outlet through which the volatiles flow out of the flow path have different cross-sectional shapes and cross-sectional areas perpendicular to the longitudinal direction of the heated aroma cartridge 200, with the inlet being triangular and the outlet being rectangular. Schematic diagram, (b) a side view seen from the left direction of the X-axis, and (c) a side view seen from the right direction of the X-axis.

[0090] In this case, in addition to the characteristics of the flow path shown in Figures 4 to 7, the effect of the surface area of ​​the upstream and downstream flow path inner walls also appears based on the cross-sectional shapes of the inlet and outlet. As can be seen from Table 1, for the same cross-sectional area, the surface area of ​​the flow path inner wall of a triangle is larger than that of a rectangle, which also has an effect in this case.

[0091] Figure 9 shows (a) a schematic cross-sectional view taken along the XY plane passing through the center of the seventh support member 570, (b) a side view seen from the left side of the X-axis, and (c) a side view seen from the right side of the X-axis of a seventh support member 570 according to one embodiment of the present invention, the seventh support member 570 having a support part 572 for preventing damage or movement of the heated aroma-generating substrate 310 and the heated aroma-generating source 300, and a flow path within the outer periphery of the support member through which volatiles generated from the heated heated aroma-generating substrate 310 pass and are cooled, the inlets through which volatiles flow into the flow path and the outlets through which volatiles flow out of the flow path have different shapes, numbers, and cross-sectional areas, the inlets are 10 squares with small cross-sectional areas, and the outlets are 2 triangles with large cross-sectional areas.

[0092] In this way, by being able to freely design the shape, number, and cross-sectional area of ​​the inlet and outlet, as can be seen from Table 2, it is possible to keep the total cross-sectional area of ​​the flow path from the inlet to the outlet constant. In particular, it is possible to control the resistance to inhalation when smoking to an appropriate level while maintaining the differences in the properties of the smoke upstream and downstream due to the cross-sectional area of ​​the flow path.

[0093] Furthermore, Figure 10 shows (a) a schematic cross-sectional view cut along the XY plane passing through the center of the eighth support member 580, (b) a side view seen from the left side of the X-axis, and (c) a side view seen from the right side of the X-axis of an eighth support member 580 according to one embodiment of the present invention, the eighth support member 580 having a support part 582 for preventing damage or movement of the heated aroma-generating substrate 310 and the heated aroma-generating source 300, and a flow path on the outer periphery of the support member through which volatiles generated from the heated heated aroma-generating substrate 310 pass and are cooled, the inlet through which volatiles flow into the flow path and the outlet through which volatiles flow out of the flow path have similar triangular shapes in cross section perpendicular to the longitudinal direction of the heated aroma cartridge 200, and the eighth support member 580 has a storage flow path 583 at the downstream end in which volatiles accumulate.

[0094] Providing such a storage flow path 583 creates convection in the flow of volatiles, causing the smoke generated upstream and downstream to mix evenly and significantly reduce the flow rate before being inhaled into the oral cavity, making it possible to enjoy smoke with a different taste and aroma than with a support member that does not have a storage flow path 583.

[0095] As described above, the support member of the present invention not only prevents damage and movement of the heated aroma generating substrate when the heated aroma cartridge is attached and when smoking, but also by controlling the shape of the flow path, the number of flow paths, and the porosity, etc., and by providing a new storage flow path, the average particle size and number of particles generated by cooling and condensing the aerosol former volatiles generated from the same heated aroma generating substrate can be varied, allowing different smoking sensations and flavors to be enjoyed. And since these sensations and flavors vary from person to person, various ways of use are possible, such as being effective as a means of increasing product variety, and there are various advantages.

[0096] Therefore, in order to make positive use of the features of the support member of the present invention, a detachable heated aroma cartridge connecting member 220 as shown in Figure 10 is used, allowing smokers to enjoy smoking with a variety of sensations and flavors using heated aroma cartridges made of the same heated aroma-generating base material.

[0097] Fig. 11 is a schematic perspective view of (a) heated aroma generation source connecting part 221 having a heated aroma generation source, (b) mouthpiece connecting part 222, and (c) detachable heated aroma cartridge connecting part 220 in which these are fitted together with female threads 2211 and male threads 2221, according to one embodiment of the present invention. And Fig. 12 is a schematic cross-sectional view taken along the XY plane of a heated aroma cartridge in which mouthpiece connecting part 222 in which fifth support member 550 and filter 700 shown in Fig. 7 are arranged and heated aroma generation source connecting part 221 in which heated aroma generation source 300 is arranged are detachably fitted together, according to one embodiment of the present invention.

[0098] By using such a heated aroma cartridge connecting member 220, by preparing a mouthpiece connecting member 222 having various support members arranged thereon, it is possible to enjoy several types of heated aroma cartridges using the heated aroma generating source connecting member having a heated aroma generating source 330, which is an aggregate of one type of heated aroma generating substrate, arranged thereon. [Industrial Applicability]

[0099] The technology for generating aerosol (smoke) from volatilized aerosol formers, utilizing the thermodynamic nucleation phenomenon and fluid dynamic flow phenomena that form the basis of the aerosol generation mechanism of the present invention, may be applicable not only to heated smoking using heated aromatic cartridges, but also to incense sticks, burning incense, powdered incense, incense liniments, etc. that handle fluids such as smoke or steam, as well as aromatherapy, etc. [Explanation of symbols]
