Description

The present invention is installed in a chamber equipped with an electrically controlled heating element of a heating type smoking device so as to be in contact with the heating element, and the user can enjoy aerosol smoke and aroma components generated by heating the heating element. Regarding aroma cartridges.

In recent years, the number of smoking enthusiasts who inhale the smoke of combusted tobacco, such as cigarettes, has decreased, as smoking separation and smoking bans have become widespread in workplaces, restaurants, and other spaces where people gather. On the other hand, the number of smoking enthusiasts who use electronic cigarettes, which are heated smoking devices that inhale smoke generated by heat transmitted by an electrically controlled heating element such as a heater, is rapidly increasing. The reason for this is that with conventional flame smoking, smokers and non-smokers around them inhale harmful substances produced by thermal decomposition and combustion (over 600 degrees Celsius) of tobacco materials and paper. According to electronic cigarettes, smokers inhale harmless smoke and aromas such as glycerin made from tobacco materials and aerosol formers at low temperatures (200 to 350 degrees Celsius) that do not lead to thermal decomposition and combustion of tobacco materials. This is because not only can smokers enjoy smoking, but also the impact on non-smokers around them can be reduced.

Broadly speaking, there are two types of electronic cigarettes (Non-patent Documents 1 and 2). One type is a capsule-type electronic cigarette and a stick-type electronic cigarette, which heat a capsule or stick containing tobacco leaves and inhale smoke. The other type is liquid electronic cigarettes, which inhale vapor by heating a scented or flavored liquid.

In particular, stick-type e-cigarettes are highly similar to traditional cigarettes in terms of shape, smoking method, taste, etc., and they also inhale less harmful substances than cigarettes, so there are many fans of stick-type e-cigarettes. Various developments are underway (for example, Patent Documents 1 to 3). Specifically, it includes an aerosol former that generates an aerosol that becomes smoke along with tobacco ingredients, a stick (electronic cigarette) that has a mouthpiece attached to an aerosol former that is processed into a cigarette-like stick shape using flavoring agents, binders, etc. This is an electronic cigarette that is smoked by attaching a cartridge (cartridge) to a heated smoking device. The mechanism of smoking is that when the aerosol forming body is placed in contact with the heat source of a heating type smoking tool and heated, volatile substances including the aerosol former are released from the aerosol forming body, and at the same time, these volatile substances are , it is drawn into the other end of the mouthpiece along with the air by the smoker's suction, and during this volatile transport process, the volatiles in the aerosol former are cooled and condensed to form a smoke-like aerosol and other The volatiles provide aroma to the smoker's mouth and nose, so that smoking can be enjoyed (Patent Document 2). According to this mechanism, in the case of heated smoking such as stick-type electronic cigarettes, tobacco leaves are heated to about 200 to 250 degrees Celsius, which is sufficient to volatilize aerosol formers such as glycerin or propylene glycol contained in the aerosol former. It can be smoked at a temperature that starts thermal decomposition. For this reason, compared to the case of flame-type smoking, which burns at a temperature of at least 600 degrees Celsius required for combustion, and even more than 900 degrees Celsius during smoking, the amount of harmful substances that are said to be generated increases as the temperature rises. The outbreak is suppressed and there are few negative effects on health.

In addition, unlike stick-type e-cigarettes, liquid-type e-cigarettes do not contain tobacco ingredients, and include beverages such as coffee, cola, and Red Bull, desserts such as chocolate, vanilla, and cream, and fruits such as oranges, lemons, and melons. It is a new smoking device that allows you to enjoy various flavors such as menthol, mint, herbal refreshing agents, etc. (Non-Patent Document 2). Specifically, it is an electronic cigarette that heats a liquid mixture of propylene glycol, vegetable glycerin, and fragrance, and inhales the evaporated volatile matter. The biggest feature of e-liquid is that it contains no harmful substances, does not emit tar or nicotine, and can be enjoyed in a wide variety of flavors.In fact, a wide variety of e-liquids are on sale.

Furthermore, in recent years, attempts have been made to combine the characteristics of these two electronic cigarettes (Patent Document 4). As mentioned above, the heated stick-shaped aerosol forming body of conventional stick-type electronic cigarettes contains tobacco components, so harmful substances such as tar and nicotine are also generated, albeit in small amounts. was. Therefore, in Patent Document 4, a stick-type electronic cigarette is invented that does not contain tobacco components, which was a problem with stick-type electronic cigarettes. In other words, instead of tobacco ingredients, we use non-tobacco materials that produce only the aroma that is effective in promoting peace of mind and body and health and beauty caused by smoking, and we use an aerosol former containing an aerosol former, a binder, etc. It is a stick-type electronic cigarette.

However, such stick-type electronic cigarettes that use only non-tobacco materials cannot use tobacco materials containing a large amount of fiber in the aerosol forming body, and in order to release various flavors, a wide variety of non-tobacco materials are used. There are problems due to the use of tobacco material.

First, in an aerosol-forming body containing tobacco material, the tobacco fibers maintain their lumpy state and prevent the tobacco material from falling off and fusing, but when non-tobacco materials that do not contain a large amount of fibers are used. In order to stably maintain the lumpy state of the heated aroma-generating sheet or the heated aroma-generating filler (hereinafter referred to as the "heated aroma-generating base material"), a large amount of a binder, etc. that functions as a fiber is required. It will be used for. Therefore, as the binder increases, the density of the heated aroma-generating substrate increases, and the aerosol former released by heating and volatile components (hereinafter referred to as "gases") from inside the heated aroma-generating substrate of non-tobacco materials increase. The flow path (hereinafter referred to as "gas flow path") is closed, making it difficult to inhale aerosol smoke and aroma components of non-tobacco materials (hereinafter referred to as "inhalation components"), and as a result, the amount of suction decreases.

In addition, since aerosol formers are made of glycerin, propylene glycol, etc. that are liquid at room temperature, the more binder there is, the more the heated aroma-generating substrate bleeds out over time, causing the heated aroma-generating substrates to fuse together. do. Therefore, the gas flow path is closed, making it difficult to suction the suction component, and as a result, the amount of suction decreases. In addition, when such fusion occurs, it becomes difficult to insert the heating element into the heated aroma-generating substrate, and the heating element may be damaged. Specifically, during transportation or storage in a warehouse or storefront, the heated aroma-generating base material may stick and harden, making it difficult for the heating element to penetrate, resulting in damage to the cartridge or damage to the heating element. There is.

On the other hand, if the amount of binder added is reduced and the gas flow path is secured, non-tobacco materials may fall off and dust may be generated, making it difficult to maintain the shape of the cartridge firmly and preventing it from being inserted into the heating element. It may be destroyed. There are also cases where these are sucked into the oral cavity.

In other words, it is necessary to maintain the generation of aerosol that becomes smoke and the generation of aroma components released from non-tobacco materials, so this problem can be solved by significantly changing the composition and blending ratio of the heated aroma-generating base material. is difficult. Therefore, there is a need for a solution that focuses on the structure of the mouthpiece, which has a large effect on the amount of suction, as well as the method of manufacturing the heated aroma-generating substrate and its filling state.

As mentioned above, the present invention solves the problem of reduced suction power due to the use of only non-tobacco materials without using any tobacco components. It is an object of the present invention to provide a fragrance cartridge that can solve the problem of a reduction in the amount of suction components due to blockage of gas flow paths between materials, and does not cause non-tobacco materials to fall off or generate dust.

Although it is referred to as a "fragrance cartridge" here, it may also be called a "smoking cartridge" or an "electronic cigarette compatible cartridge."

This also applies to those that use non-tobacco materials that do not contain tobacco components as sources of fragrance.

"Fragrance" means "good smell" and includes the scent that wafts from the material itself (fragrance), the scent that wafts in the space when heated (aroma), the scent that wafts in the mouth when inhaled (flavor), etc. .

"Smoking" generally means smoking cigarettes, but here it simply means "enjoying smoke," "tasting smoke," or "enjoying smoke," and refers to the source of smoke. This is not limited to tobacco, but also applies to products made from non-tobacco materials. Furthermore, "smoke" here includes "things that look like smoke" and "things in the form of smoke," such as droplets dispersed in the air such as aerosols.

An "electronic cigarette compatible cartridge" is also simply defined as a "cartridge that can be used interchangeably with an electronic cigarette cartridge containing a tobacco component", regardless of whether it contains a tobacco component.

More specifically, the smoker is attached to a heating type smoking device having an electrically controlled heating element in the chamber so as to come into contact with the heating element, and enjoys the aerosol smoke and aroma components generated by heating the heating element. In the cylindrical aroma cartridge, a mouthpiece equipped with a filter for filtering at least smoke and aroma components is adjacent to a heated aroma generating body wrapped with a heated aroma generating base material that contacts at least the heating element. The cartridge is wrapped in an exterior body, and the mouthpiece has a function to improve the amount of gas suctioned, a mechanism that has the function of capturing fallen objects such as non-tobacco materials and dust, and a mechanism that has the function of trapping non-tobacco materials and dust, as well as a mechanism for sucking gas into the heated aroma generating body. It is an object of the present invention to provide an aroma cartridge having a material having a structure that does not reduce the amount of non-tobacco materials and does not cause shedding of non-tobacco materials or dust.

That is, the aroma cartridge of the present invention includes a heated aroma generating body wrapped with a heated aroma generating base material that contacts the heating element, and aerosol smoke and aroma components generated by heating from the heating element. A mouthpiece equipped with a filter for filtration, and a cartridge exterior whose outer periphery is wrapped so as to connect the heated aroma generator and the mouthpiece, at least one of the heated aroma generator and the mouthpiece. comprises at least one of means for optimizing the inhalation of said smoke and said aroma components and a gas production sustaining material of said smoke and said aroma components.

Such suction optimization means and gas production sustaining material refer to the following structures and materials, respectively. The suction optimization means has a structure that improves the suction amount of the mouthpiece, and a structure that prevents and captures the generation of falling objects such as non-tobacco materials and dust of the heated aroma generator. More specifically, a cavity is provided in the filter that makes up the mouthpiece to increase the amount of suction by expanding the gas flow path, and a support that prevents the heated aroma generator that makes up the mouthpiece from moving toward the mouthpiece. A shape reinforcing member installed in the mouthpiece that prevents a decrease in suction volume due to deformation, an insulating material installed in the mouthpiece that prevents joints from being damaged due to heat diffusion, and prevents the generation of falling objects such as non-tobacco materials and dust. means the lid material and supplementary partition material. The gas generation maintaining material is a material that does not block the flow path of the gas released from the heated aroma generator. More specifically, a heated aroma-generating base material whose internal structure has been improved by a manufacturing method, a heated aroma-generating base material constituting a heated aroma-generating body with an optimized blending amount, and a heated aroma-generating base material whose internal structure has been improved by a manufacturing method. This heated aroma-generating base material has an improved filling rate of inorganic particles present inside and/or on the surface of the heated aroma-generating base material. Hereinafter, the structure and materials of the present invention will be explained in detail.

First, in the aroma cartridge of the present invention, the filter is made of fibers molded into a cylindrical shape and constitutes all or a part of the mouthpiece, and the suction optimization means is installed in the filter in the longitudinal direction. It has a cavity that does not penetrate through the This filter is made of commonly used polyester fibers such as cellulose acetate (CA) fibers and polyethylene terephthalate (PET), and is a filter that is made of commonly used polyester fibers such as cellulose acetate (CA) fibers and polyethylene terephthalate (PET). In the case of aroma cartridges, since the flow rate of gas inhaled by a typical smoker is not sufficient, the amount of gas inhaled is increased by using a cavity.

The shape and number of cavities are not particularly limited and may be determined as appropriate depending on the type of heated aroma generator, but the effect of increasing the amount of gas inhaled by a typical smoker is Considering the difficulty of the manufacturing method of the cavity, it is preferable that at least one of the filters be disposed at one end or both ends in the longitudinal direction of the filter.

Further, the position where the cavity is formed is arranged so that when the smoker inhales, the gas to be inhaled uniformly enters the entire oral cavity. When there is only one cavity, it is preferable to form it on the central axis of a cylinder existing in the longitudinal direction of the filter. When there are two cavities, it is preferable to form them with the central axis of a cylinder existing in the longitudinal direction of the filter as the center of interest. Furthermore, when there are three or more filters, the center is on the central axis of the cylinder that exists in the longitudinal direction of the filter, and on the central axis of the cylinder that exists in the longitudinal direction of the filter, and on the central axis of the cylinder that exists in the longitudinal direction of the filter. It is preferable that they be arranged at rotationally symmetrical positions.

Furthermore, regarding the shape of the cavity, from the viewpoint of increasing the amount of gas inhaled by a typical smoker and the difficulty of manufacturing the cavity, it is preferable that the cavity is columnar or conical. The shape of the bottom surface of the shape is not limited. However, since it is efficient to form these cavities by general mechanical drilling, electrical discharge machining, or laser machining, a cylindrical or conical shape is preferable from the viewpoint of workability.

Such a filter may constitute the entire mouthpiece by itself, or may be a part of the mouthpiece. When part of the mouthpiece is a filter, the remaining part is preferably a cavity formed by the cartridge outer casing. The arrangement of the filter and the cavity is not particularly limited, and the aromatic body to be heated and the filter may be adjacent to each other, or the aromatic body to be heated and the cavity may be adjacent to each other. The cartridge exterior body is usually made of polyolefin resin such as PE, PP, PET resin, CA resin, thin film such as polylactic acid (PLA), thin paper, etc. When forming a mouthpiece, it needs to be thick enough to maintain its strength as a mouthpiece, although it depends on the material.

Furthermore, the mouthpiece can be equipped with a member having a desirable function other than the filter to improve the function of the mouthpiece. Typical such members include a support member for preventing the heated aroma generator from moving toward the mouthpiece, and a support member for preventing the heated aroma generator from moving toward the mouthpiece, and a support member for cooling the heated aroma generator after the aerosol former has volatilized. There is a cooling member to promote smoke production and reduce the temperature of the gas, which together with a filter may form a mouthpiece. Either one or both of these members may be used. When either one is applied, it is arranged between the heated aroma generator and the filter. When both are applied, the support member and the cooling member are arranged between the heated aroma generator and the filter in this order or in the reverse order.

The reason why it is necessary to lower the temperature of the gas using a cooling member is not only for the purpose of cooling and condensing the volatilized aerosol former to generate smoke, but also for the purpose of cooling and condensing the vaporized aerosol former to generate smoke. The extremely short distance between the heating part and the mouthpiece lowers the temperature of the gas itself, making it possible to enjoy a pleasant smoking experience in the mouth. Therefore, the cooling member preferably functions as a heat exchanger, and a cylindrical porous body having continuous pores with a high porosity, a cylindrical tube having many through holes, or the like is used. The porosity must be at least 50%, preferably 70 to 90%. As materials, polyolefin resins such as PE and PP, PET resins, CA resins, polylactic acid (PLA), etc. have been used, but metal foils such as aluminum with high thermal conductivity are wrapped around these, and More preferably, it is a metal itself.

In this way, the mouthpiece makes it easy for the smoker to hold the aroma cartridge in the mouth, and has a filter as an essential component that filters the gas and makes the taste of the gas mellow. A cooling member can be provided. When this structure is used, since it is the filter that prevents the suction of gas, it becomes possible to shorten the length of the filter and increase the amount of suction. Therefore, instead of providing the cavity as described above, we investigated a mouthpiece structure that shortens the filter and increases the amount of suction.

The length of the aroma cartridge itself and the length of the heated aroma generator are determined according to the structure of the heated smoking device, so if the filter of the mouthpiece is shortened, part of the filter will be replaced with a support member. . Conventionally, the supporting member has a hollow cylindrical structure with a thin side surface and is made of materials such as: Inexpensive polyolefin resins such as polyethylene (PE) and polypropylene (PP), plastics such as CA resin, and paper have been used. In order not to obstruct the passage of gas, it is preferable that the support member is hollow and has a thinner side surface. However, if the length of such a support member is increased by shortening the filter, a problem arises in that the mouthpiece is easily deformed.

To solve this problem, the present invention provides an aroma cartridge equipped with a mouthpiece composed of at least a filter and a support member, in which the mouthpiece deforms even if the length of the support member is increased and the thickness of the side surface is decreased. The purpose of the present invention is to provide a structure of a support member that does not reduce the amount of suction.

That is, in this aroma cartridge, the mouthpiece has a support member including a through hole that prevents the heated aroma generator from moving toward the mouthpiece, and the support member and the central axis of the cylinder of the through hole are approximately the same. The suction optimization means comprises a shape reinforcing element which is fixedly or movably arranged in the through hole. More specifically, this shape reinforcing member includes at least one plate-like member that has the support member and the axis of the through hole in the plane and contacts the inner wall of the through hole. By disposing such a plate member in the cylindrical through hole of the support member, there is no need to change the material even if the length of the cylindrical support member is increased and the thickness of the side surface is reduced. It becomes possible to prevent deformation of the support member. The shape of this plate-like member is preferably a cross section cut in the axial direction of a cylinder, that is, a rectangle. From the viewpoint of suction amount, the thinner the thickness is, the more preferable it is, and the smaller the number, the better, but deformation is prevented. In consideration of the fact that the polyolefin resin has a thickness of 2 to 4 and a thickness of 0.1 to 0.5 mm, it is preferable to use polyolefin resin.

Furthermore, the shape reinforcing member has a concentric cylinder having an axis substantially the same as the central axis of the cylinder of the support member and the through hole, and a radius smaller than the radius of the through hole, and It is more preferable to include a plate-shaped member formed so as to be in contact with the inner wall of the through hole in order to prevent deformation of the support member, and from the viewpoint of gas suction, it is even more preferable that the concentric cylinder is hollow. preferable.

In this way, the support member is provided with a shape reinforcing member adjacent to the heated aroma generator to prevent the heated aroma generator from moving toward the mouthpiece, and the filter is adjacent to the support member. In aroma cartridges equipped with a mouthpiece, gas suction can be optimized without deforming the support, but in order to control gas suction more broadly, a filter with a cavity can be used as a filter. It is more preferable to do so. Furthermore, a cooling member that can efficiently turn the volatilized aerosol pharmaceutical into aerosol smoke may be disposed between the filter and the support member. In any of these cases, in order to further optimize the suction amount, it is preferable to use a filter having a cavity as the filter.

On the other hand, as the amount of suction increases due to improvements in the filter and support members, the heat of the gas becomes more convected and transmitted from the heating element to the filter, resulting in a decrease in the bonding force between the components that make up the aroma cartridge. There is. The locations of such joint surfaces vary depending on the configuration of the aroma cartridge, but include the interface between the heated aroma generator and the filter, the support member, the cooling member, and the cartridge exterior body, and the interface between the filter and the support member, the cooling member, and the cartridge exterior body. , the interface between the supporting member, the cooling member and the cartridge exterior body, the interface between the cooling member and the cartridge exterior body, etc.

If the bonding strength at each interface is reduced, gas will leak and the amount of suction will be adversely affected, so it is preferable to provide a heat insulating member between the heated aroma generator and the mouthpiece. This heat insulating member does not distribute high-temperature gas throughout the body like the support member adjacent to the heated aromatic body, but instead uses a sponge-like insulating porous body made of plastic with continuous pores with long channels. Preferably, any material having the function of retaining and cooling to some extent may be used. Therefore, the length of the heat insulating member is extremely short, and there is no need for a cooling function up to the cooling member, and it is preferable to use the heat insulating member in place of the support member that prevents the heated aroma generating body from moving toward the mouthpiece.

In addition, in the case of a heating type smoking device (Figure 3) in which the chamber is covered with a heating element, instead of a typical heating type smoking device (Figure 2) equipped with a needle-shaped heating element at the bottom of the chamber, an aroma cartridge is used. Since the effect of heat on the joint is greater and the bonding force at the interface of each member as described above is significantly reduced, it is necessary to provide a heat insulating member to prevent the bonding force from decreasing, that is, the amount of suction. As described above, the present invention provides a heat insulating member between the heated aroma generator and the mouthpiece as a suction optimization means, from the viewpoint of eliminating the influence of the heat of the heating element and preventing a reduction in the amount of suction. It also provides an intervening fragrance cartridge.

Furthermore, since the heated aroma-generating base material emits various aromas, the fiber component may be extremely reduced. In such cases, the blending amount of the binder is adjusted, but in order to maintain the aroma, it is not possible to significantly reduce the blending ratio of non-tobacco materials, and non-tobacco materials may fall off. Objects and dust are more likely to be generated than usual. These particles are carried toward the mouthpiece by smoking and become a factor that clogs the gaps in the filter and cooling member, drastically reducing the amount of suction. In addition, in the case of a heated aroma-generating base material having such a composition, it is easy to generate fallen substances, dust, etc. even when the aroma cartridge is stuck into a needle-shaped heating element.

Therefore, the present invention provides an aroma cartridge in which a lid material is disposed at the end of the heated aroma generating body on the mouthpiece side and a partition material is disposed at the end on the opposite side of the mouthpiece as a means for optimizing suction. There is also. Depending on the state of the heated aroma-generating substrate and the heated aroma-generating body in which they are bundled, either one of the lid material and the partition wall material may be provided, or both may be provided. This lid material and/or partition wall material prevents clogging of the filter and/or cooling member due to fallen objects and dust, and ensures a stable suction amount.

So far, a solution for structurally improving the optimization of gas suction in a fragrance cartridge has been described. However, in order to optimize suction, it is also necessary to improve heated aroma generators that release gas when heated. The amount of gas released from the heated aroma generator is closely related to the amount of suction described above, and this point will be explained below. In the present invention, materials that stabilize the amount of gas released are referred to as gas production sustaining materials.

The reason why the improvement in the amount of gas released by heating the heated aroma generator is not sustained has already been explained, but since it is an important point in the present invention, it will be explained again. In an aerosol-forming body containing tobacco material, the tobacco fibers maintain their lumpy state and prevent the tobacco material from falling off and fusing. However, when non-tobacco materials that do not contain a large amount of fibers are used, In order to stably maintain the bulk state of the heated aroma-generating base material, a large amount of a binder or the like that functions as a fiber must be used. Therefore, as the binder increases, the density of the heated aroma-generating substrate increases, the gas flow path is closed, and it becomes difficult to suction the suction components.

In addition, since aerosol formers are made of glycerin, propylene glycol, etc. that are liquid at room temperature, the more binder there is, the more likely it is to bleed out from the heated aroma-generating substrate over time, and the heated aroma-generating substrates will melt together. As a result, the flow path between the heated aroma-generating substrates is closed, making it difficult to suction the suction component. In addition, when such fusion occurs, it becomes difficult to insert the heating element into the heated aroma-generating substrate, and the heating element may be damaged. On the other hand, if the amount of binder added is reduced and the gas flow path is ensured, non-tobacco materials may fall off and dust may be generated, making it difficult to maintain the shape of the aroma cartridge firmly, making it difficult to insert it into the heating element. If you do so, it may be destroyed. There are also cases where these are sucked into the oral cavity.

Therefore, in the present invention, it was first discovered that the above-mentioned problems can be solved by a method [apparatus] for producing a heated aroma-generating substrate. Although the following description will mainly be based on a manufacturing method that includes each step, it is clear that there are manufacturing devices that can carry out the manufacturing method as a whole by being equipped with means for executing each step. . Therefore, the manufacturing method and the manufacturing device will be described simultaneously (overlappingly) as "process [means]" and "method [apparatus]" without duplication.

Now, the reason why the above problem can be solved by the method [device] for producing a heated aroma-generating base material is that the heated aroma-generating base material is mixed with a non-tobacco material, an aerosol former, and a medium such as pure water and alcohol. Compression molding methods such as paper-making methods, roll presses, presses, and It is manufactured by drying a sheet formed by a casting method, etc., and then cutting it, and the internal structure of the heated aroma-generating base material changes variously depending on the manufacturing method [equipment] in the forming and drying process [means]. This is thought to be due to the

The basis for this is that, for example, in blends of different polymers, the phase separation structure of the blend is affected by the manufacturing method [equipment] and manufacturing conditions, and in the case of emulsions and suspensions that disperse oil in water, Whether it is a water droplet type or an oil-in-water type is influenced by various factors such as the type of oil, the blending ratio of oil and water, and the type of surfactant. Furthermore, it is almost impossible to analyze clear differences in the structure of heated aroma-generating substrates due to differences in manufacturing methods [equipment] due to the complexity of the material systems involved. It is thought that a great deal of effort is required to find a law. The reason for the fact that differences in the internal structure of polymer blends, emulsions, etc. occur depending on the manufacturing method [equipment] was based on the fact that the substances that are blended are limited, the history of research is long, and analytical methods have not been established. This is because the differences in structure caused by manufacturing conditions are clear.

Various methods and apparatuses for producing heated aroma-generating substrates have already been studied, and one example is as follows. The process [means] of preparing non-tobacco materials by dry-mixing after drying and crushing non-tobacco materials, as well as aerosol formers, binders, anti-stick agents, fragrances, non-tobacco extracts, antibacterial preservatives, etc. A step [means] of preparing the selected material, a step [means] of preparing pure water and alcohol, a wet mixing step [means] of mixing these prepared materials all at once, and a wet mixing step [means] of preparing the selected materials. A papermaking process [means] for producing a water-containing sheet from the produced slurry, a forming process [means] for producing a sheet by roll-pressing the paper-made water-containing sheet, and a process for drying the sheet produced in the forming process [means]. This is a method [apparatus] for producing a heated aroma filler by cutting a heated aroma generating sheet produced from [means].

However, it is difficult to maintain the heated aroma-generating base material produced by such a method [apparatus] in a lumpy state, so a large amount of binder is required, and the heated aroma-generating base material is difficult to maintain in a lumpy state. There was a problem that fusion of the base materials was likely to occur. Therefore, the amount of gas emitted from the heated aroma generator using this filling material changes greatly over time, making it impossible for smokers to stably inhale gas.

In the aroma cartridge of the present invention, the material that stabilizes the amount of gas emitted from the heated aroma generator, that is, the gas generation sustaining material, is first produced by a dry mixing process [means] of mixing dried and pulverized non-tobacco materials. ], non-tobacco material produced by dry blending process [means], aerosol former, binder or thickener, cross-linked polyvinylpyrrolidone (PVP), fragrance, non-tobacco extract, β-cyclodextrin, microcrystalline cellulose. , and a material selected from antibacterial preservatives into a mixture of alcohol and pure water; and a non-tobacco material produced by the first wet mixing step [means]. A second wet mixing step [means] for producing a slurry containing non-tobacco materials, etc. by further adding pure water and/or alcohol to a mixed solution of alcohol and pure water containing such materials, and a second wet mixing step [means] for producing a slurry containing non-tobacco materials, etc. A papermaking process [means] that produces a water-containing sheet from the slurry produced in [means], a sheet forming process [means] that compresses the water-containing sheet and processes it into a sheet, and a sheet produced in the sheet forming process [means]. This heated aroma-generating base material is manufactured from a drying process [means] of drying to produce a heated aroma-generating sheet, and a sheet processing process [means] of cutting or bending the heated aroma-generating sheet.

A feature of the production in this method [apparatus] is the second wet mixing. This second wet mixing process with the addition of pure water and alcohol improves the dispersion state of the aerosol former such as polypropylene glycol or glycerin and the non-tobacco material. The lumpy state of the aroma-generating base material can be stabilized, and bleed-out of the aerosol former can be reduced. In particular, the alcohol is preferably a lower monoalcohol such as ethanol or propanol because it is effective, and the amount added is preferably 0.1 to 10 parts by weight based on 100 parts by weight of the non-tobacco material.

The gas generation sustaining material in the second fragrance cartridge of the present invention is produced by a dry mixing process [means] of mixing dried and pulverized non-tobacco materials, a non-tobacco material produced by the dry mixing process [means], and an aerosol. A material selected from a former, a binder or thickener, a cross-linked PVP, a flavor, a non-tobacco extract, a β-cyclodextrin, a microcrystalline cellulose, and an antimicrobial preservative are mixed into the alcohol and pure water mixture. Further adding pure water and/or alcohol to the first wet mixing step [means] and the alcohol and pure water mixture containing the non-tobacco material etc. produced by the first wet mixing step [means]. A second wet mixing process [means] for producing a slurry containing non-tobacco materials, etc., a papermaking process [means] for producing a water-containing sheet from the slurry produced in the second wet mixing process [means], and a water-containing sheet. A sheet forming process [means] in which the water content is reduced to less than 50% by mass through the sheet forming process [means], in which the water content is reduced to less than 50% by mass. process [means], a drying process [means] to produce a heated aroma-generating sheet by drying the sheet produced in the aerosol former absorption process [means], and sheet processing to cut or bend the heated aroma-generating sheet This is a heated aroma-generating base material produced from the process [means].

The manufacturing feature of this method [equipment] is also in the second wet mixing, and the alcohol is preferably a lower monoalcohol such as ethanol or propanol, and the amount added is 0.000 parts by weight per 100 parts by mass of the non-tobacco material. The fact that it is preferably 1 to 10 parts by mass is the same as in the first production method [equipment], but the second production method [equipment] is characterized by further reducing the water content to less than 50% by mass. The reason lies in the addition of an aerosol former absorption step [means] in which the aerosol former is applied or immersed in the water-containing sheet. In the conventional manufacturing method [equipment], the dispersion state of the aerosol former and the non-tobacco material is poor, and the aerosol former and the non-tobacco material are mixed in an undried heated aroma-generating base sheet with a moisture content of less than 50% by mass. was free, making it difficult to absorb the aerosol former. However, since the dispersion state is improved by the second wet process [means], the aerosol former is absorbed into the sheet in the aerosol former absorption process [means], so the amount of the aerosol former and binder added is the first. Even with the same manufacturing method [equipment], the lumpy state of the heated aroma-generating base material can be stabilized, bleed-out of the aerosol former can be reduced, and the aerosol former is more easily volatilized by heating.

The gas generation sustaining material in the third aroma cartridge of the present invention is produced by a wet mixing process [means] in which dried and ground non-tobacco material is mixed with pure water to produce a slurry of non-tobacco material; A paper-making process [means] for producing a water-containing sheet from the slurry produced in [means], a sheet-forming process [means] for processing the water-containing sheet into a sheet by compressing or casting, and a sheet-forming process [means] a drying step [means] to reduce the moisture content of the dried sheet to less than 50% by weight; and a drying step [means] in which the sheet produced in the drying step [means] is coated with an aerosol former, a binder or thickener, a cross-linked PVP, a flavoring agent, and a non-tobacco extract. Absorption by applying or soaking a mixture of alcohol and pure water of a material selected from substances, β-cyclodextrin, microcrystalline cellulose, a concentrated liquid of water discharged from the sheet forming process, and an antibacterial preservative. and an adsorption step [means], a drying step [means] of drying the sheet produced in the absorption and adsorption step [means] to produce a heated aroma-generating sheet, and cutting or bending the heated aroma-generating sheet. This is a heated aroma-generating base material manufactured by sheet processing process [means].

In the first and second manufacturing methods [equipment], a water-containing sheet was formed by making paper from a slurry obtained by wet-mixing all materials such as non-tobacco materials with pure water and alcohol, but in the third manufacturing method [equipment] ] is characterized in that a water-containing seed is produced from a slurry of non-tobacco material alone, and the dried sheet absorbs and adsorbs other materials such as an aerosol former. In the first and second manufacturing methods [equipment], wet dispersion of all materials was itself a problem, as was the case with improved dispersion of non-tobacco material and aerosol former. Therefore, as a result of considering a manufacturing method [device] that does not go through the process [means] of mixing and dispersing non-tobacco materials and an aerosol former, we found that, as in the third manufacturing method [device], dried non-tobacco materials It was discovered that a mixture of pure water and alcohol from other materials such as an aerosol former quickly permeates, is absorbed and adsorbed into the sheet, leading to the present invention. The bulk state of the heated aroma-generating substrate produced by this method [apparatus] was stable, and the bleed-out of the aerosol former was also reduced.

The gas production sustaining material in the fourth fragrance cartridge of the present invention comprises a non-tobacco material preparation step [means] of drying and pulverizing non-tobacco material, and at least a flavoring agent and/or a non-tobacco material extract and a cross-linked PVP and/or A flavor and/or non-tobacco extract mixing step [means] of mixing β-cyclodextrin with alcohol to make the flavor and/or non-tobacco extract stay in the cross-linked PVP and/or β-cyclodextrin; and at least an aerosol former. Aerosol former dissolution step [means] of mixing a binder or thickener with pure water, the material produced in the non-tobacco material preparation step [means], and a flavor and/or non-tobacco extract dissolution step [means] A wet mixing process [means] for mixing the material produced in the aerosol former melting process [means] with a material produced in the aerosol former melting process [means], and a heated aroma-generating sheet compressed from the material produced in the wet mixing process [means]. This is a heated aroma-generating base material manufactured by a sheet forming process [means] for producing the heated aroma-generating sheet and a sheet processing process [means] for cutting or bending the heated aroma-generating sheet.

The previous manufacturing method [equipment] was characterized by forming a sheet from a slurry of non-tobacco materials through a papermaking process [means], but in view of the results of the third manufacturing method [equipment], we decided to Casting a sheet from a slurry of materials with different properties, such as wood, is problematic in itself, so instead of going through a large amount of pure water and alcohol slurry, it is possible to cast a sheet from a slurry of materials with different properties. A mixture of the materials and the like is formed into a sheet of heated aroma-generating substrate using a roll press such as a three-roll machine. In this method [apparatus], large shearing force and compressive force are applied to the mixture of non-tobacco materials, so it is thought that all the materials are uniformly kneaded and dispersed.

Here, at least a flavor and/or a non-tobacco material extract and a cross-linked PVP and/or β-cyclodextrin are mixed with alcohol, and the flavor and/or non-tobacco extract is suspended in the cross-linked PVP and/or β-cyclodextrin. and an aerosol former dissolving step [means] of mixing at least an aerosol former and a binder or a thickener with pure water, and an aerosol former dissolving step [means] of mixing at least an aerosol former and a binder or a thickener with pure water. It is important to previously dissolve materials that can be dissolved in pure water and alcohol, such as thickeners. In particular, when menthol and/or xylitol are used as fragrances, they are sorbed to cross-linked PVP and/or β-cyclodextrin, stably existing in the heated aroma-generating substrate, and preventing bleed-out of the aerosol former. Because of the inhibitory effect, at least the flavor and/or non-tobacco material extract and cross-linked PVP and/or β-cyclodextrin are mixed in alcohol to mix the flavor and/or non-tobacco extract with cross-linked PVP and/or β-cyclodextrin. The mixing step [means] for retaining in cyclodextrin plays a very important role.

By adopting this manufacturing method [equipment], the bulk state of the heated aroma-generating base material is stable, the bleed-out of the aerosol former can be significantly reduced, and there is no fusion of the heated aroma-generating base material. The volatilization of gas due to the heating of the heated aroma generator was promoted, and it was possible to prevent a decrease in the amount of suction over time.

Furthermore, in the sheet forming step [means] of this manufacturing method [apparatus], non-tobacco materials, aerosol formers, binders or thickeners, cross-linked PVP, fragrances, non-tobacco extracts, β-cyclodextrin, microcrystalline cellulose, It is preferable to add a step [means] of adding a material selected from an antibacterial preservative and pure water. This process [means] can promote kneading by shearing force and compressive force in the sheet forming process [means], can control the moisture content, and can increase the volatility of the aerosol former.

The gas generation sustaining materials in the fifth aroma cartridge of the present invention include dried and pulverized non-tobacco material, a first binder aqueous solution prepared by dissolving the first binder in pure water, an aerosol former, and crosslinked PVP. , a flavor, a non-tobacco extract, β-cyclodextrin, microcrystalline cellulose, and an antibacterial preservative. A curing process [means] for stabilizing the liquid mixture produced in the [means], and a second aqueous binder solution in which the curing liquid mixture produced in the curing process [means] and a second binder are dissolved in pure water. a second wet mixing step [means] for mixing the materials; a sheet forming step [means] for producing a heated aroma-generating sheet by compressing the material produced in the second wet mixing step [means]; This is a heated aroma-generating base material manufactured from a sheet processing step [means] of cutting or bending a heated aroma-generating sheet. Also, in this manufacturing method [device], as in the fourth manufacturing method [device], in the sheet forming step [means], non-tobacco material, aerosol former, binder or thickener, cross-linked PVP, fragrance, non-tobacco extract It is preferable to add a step [means] of adding a material selected from a compound, β-cyclodextrin, microcrystalline cellulose, an antibacterial preservative, and pure water.

In particular, this manufacturing method [apparatus] includes a step [means] for curing the mixed liquid, and a step [means] for adding the binder in two parts before and after the curing step [means]. That's true. The binder is preferably a modified cellulose polymer for the first use, and preferably a polysaccharide polymer other than cellulose for the second use.

The curing process [means] means that the dispersion state of the mixture of non-tobacco materials changes over time, and it is assumed that it leads to a stable and uniform dispersion state with the lowest energy. This is thought to be because the state change can form a lumpy state of the heated aroma-generating substrate.

In addition, by adding the binder in two parts, the mixture can be sufficiently dispersed even if the amount of binder added is reduced, and the viscosity can be easily adjusted. It is closely related to the curing process [means]. By adding the binder for the first time and curing it, a stable dispersion state is created, making it easier to add the binder for the second time, reducing the amount added and making it easier to adjust the viscosity. Become. Therefore, in the first step, a modified cellulose-based polymer is preferred because of its superior dispersion ability, and in the second step, a non-cellulose-based polysaccharide polymer is preferred because it has superior ability as a thickener to adjust viscosity.

Such modified cellulose-based polymers include methylcellulose, ethylcellulose, carboxymethylcellulose, carboxyethylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, and sodium salts, potassium salts, and calcium salts of carboxymethylcellulose and carboxyethylcellulose. It is preferable to use one or more of these, and the polysaccharide polymers include konjac mannan (glucomannan), guar gum, pectin, carrageenan, tamarin seed gum, gum arabic, soybean polysaccharide, locust bean gum, karaya gum, xanthan gum, It is preferable to use one or more of agar and agar.

The amount of the binder to be blended is preferably 5 to 20 parts by mass of the first binder and 0.1 to 5 parts by mass of the second binder per 100 parts by mass of the non-tobacco material.

There are also appropriate conditions for the curing step [means] to lead to a stable dispersion state, and it is preferably carried out at 15 to 30°C for 72 to 336 hours. Appropriate temperature conditions are necessary because the binder is a polymer with hydroxyl and carboxyl groups, so the presence or absence of hydrogen bond formation causes a difference in the state of the molecules dissolved in pure water and alcohol, which depends on the temperature. This is thought to be due to this, and the optimum temperature range was determined as an experimental result. Although a minimum amount of time is required for the dispersion state to change over time and become stable, there will be no significant change if more time is required than necessary, and productivity will be reduced.

Above, we have explained the solution of optimizing the heated aroma-generating base material, which is a material that stably releases gas from the heated aroma-generating body, in other words, the material that sustains gas production, using the manufacturing method [device]. We devised a material that releases gas more actively and stably.

This gas production sustaining material is an inorganic particle. There are two effects of inorganic particles depending on where they are present. One is the case where inorganic particles are present inside the heated aromatic filling. By adding inorganic particles to the heated aroma-generating body, the density of the heated aroma-generating base material is reduced, the gas flow path is no longer blocked, and gas suction is not difficult. The other case is when the inorganic particles are on the surface of the heated aroma-generating sheet or the heated aroma-generating substrate. Even if the aerosol former bleeds out from the heated aroma-generating base material over time, the inorganic particles can prevent the fusion phenomenon between the heated aroma-generating base materials and the heated aroma-generating sheet or the heated aroma-generating base material. The flow path between the aroma-generating substrates is not closed, which solves the problem of difficulty in suctioning the suction components. Further, since the fusion of the heated aroma-generating sheet or the heated aroma-generating base material is eliminated, it is also solved that it becomes difficult to insert the heating element into the heated aroma-generating base material. Furthermore, introducing inorganic particles into the heated aroma-generating body reduces the contact area between the heating element and the organic component of the heated aroma-generating base material, regardless of whether it is inside or on the surface of the heated aroma-generating base material. This also has the effect of reducing dirt on the heating element of the heating type smoking device.

In order to make such inorganic particles exist inside the heated aroma-generating base material as a material that sustains gas generation, the composition of the heated aroma-generating base material must be used as a raw material in the above-mentioned manufacturing process of the heated aroma-generating base material. Just add it to the food. The step [means] of adding inorganic particles is not particularly limited, but it is preferable to add them before wet mixing of tobacco materials and the like.

On the other hand, in order to have the inorganic particles present on the surface of the heated aroma-generating substrate, in the above-mentioned five manufacturing methods [equipment], after the step [means] in which the heated aroma-generating sheet is manufactured, the inorganic particles are added to the heated aroma-generating substrate. After the step [means] of dispersing the inorganic particles onto the aroma-generating sheet and the sheet processing step [means] in which the heated aroma-generating substrate is manufactured, there is a step [means] of dispersing the inorganic particles onto the heated aroma-generating substrate.

Inorganic particles include metal oxides such as magnesium oxide, calcium oxide, titanium oxide, iron oxide, and alumina, metal carbonates such as magnesium carbonate and calcium carbonate, metal phosphates such as calcium phosphate, potassium titanate, and magnesium titanate. It is preferable to use silicon oxide such as titanate, zeolite, colloidal silica, fumed silica, etc., and it is more preferable that the average particle diameter is 1 to 100 μm. Furthermore, in order for the inorganic particles to function effectively, it is preferable that 0.1 to 10 parts by mass of the inorganic particles be added to 100 parts by mass of the non-tobacco material.

As described above, the aroma cartridge of the present invention includes a heated aroma generating body wrapped with a heated aroma generating base material that contacts the heating element, and aerosol smoke and aroma components generated by heating from the heating element. a mouthpiece equipped with a filter for filtering the air; and a cartridge exterior whose outer periphery is wrapped to connect the heated aroma generator and the mouthpiece, and at least one of the heated aroma generator and the mouthpiece, and at least one of a means for optimizing the inhalation of smoke and aroma components and a material that sustains the gas production of smoke and aroma components. In the above, the suction optimization means and the gas generation sustaining material in the aroma cartridge of the present invention have been explained, but below, the invention that complements these will be further explained.

First, it is preferable for the filling rate of the heated aroma-generating base material constituting the heated aroma-generating body to be 60 to 90% for stable gas suction. If this filling rate is exceeded, it will be difficult to suction the gas, and if the filling rate is less than this filling rate, the amount of gas released will be insufficient. In particular, in order to prevent the heated aroma-generating base material from fusing over time, it is preferable that the filling rate is 60 to 73%. When the filling rate exceeds 73%, the fusion of the heated aroma-generating substrate becomes noticeable over time. However, this does not apply to heated aroma-generating substrates manufactured using the improved manufacturing method [equipment] described above, or heated aroma-generating substrates in which inorganic particles are present inside or on the surface. Even if the ratio exceeds 73%, the fusion does not become severe over time.

Further, the amount of aerosol former contained in the heated aroma-generating base material is preferably 50 to 80 parts by mass based on 100 parts by mass of the non-tobacco material. If the amount is less than this, the amount of volatilization of the aerosol former that becomes an aerosol will be insufficient, and if it is more than this amount, the aerosol former will bleed out from the heated aroma-generating base material, and the heated aroma-generating base material will be It fuses violently.

Furthermore, cross-linked PVP plays a role of stabilizing the bulk state of the heated aroma-generating base material and retaining aroma components such as menthol and xylitol, and is used in amounts of 7 to 25 parts by mass per 100 parts by mass of non-tobacco material. If the amount is less than this amount, the function of crosslinked PVP cannot be expressed, and if it is more than this amount, the aroma components due to non-tobacco materials etc. will be insufficient.

The amount of microcrystalline cellulose is preferably 7 to 25 parts by mass based on 100 parts by mass of the non-tobacco material. This microcrystalline cellulose is a fluid powder that does not dissolve in organic solvents such as water and ethanol, and is used as an excipient for forming pharmaceutical tablets. This is because microcrystalline cellulose has fluidity and high compressibility with large volume changes, making it effective in preventing cohesive failure and adhesion to molds when forming tablets by direct compression. A similar effect can be obtained in a heated aroma-generating base material, and if the amount is less than the above-mentioned amount, this function cannot be expressed. On the other hand, if the blending amount exceeds this amount, the blending ratio of other materials becomes relatively insufficient, which adversely affects the function as a heated aroma-generating base material.

Finally, β-cyclodextrin is preferably used in an amount of 0.2 to 1.0 parts by weight based on 100 parts by weight of the non-tobacco material. β-Cyclodextrin plays the role of retaining aroma components such as menthol and xylitol, so at least this amount is required, but adding too much will inhibit its function as a heated aroma-generating base material. . In particular, it is known to include menthol, and when menthol is used as a fragrance component, it is preferably added.

The present invention will be explained in more detail below using drawings and embodiments, but the present invention is not limited to these and can be implemented with various changes within the scope of the gist of the present invention. and is limited only by the technical idea described in the claims.

Fig. 1 shows a heating type smoking device with an electrically controlled heating element in the chamber, which is attached so as to come into contact with the heating element, and the user can enjoy the aerosol smoke and aroma components generated by heating the heating element. It is a schematic diagram showing the general structure of a cylindrical aroma cartridge and the steps [means] of the manufacturing method [apparatus]. The fragrance cartridge of the present invention basically has the same structure and is assembled in the same way, except that no tobacco component is used as the heated fragrance generator that generates the aerosol that is heated by the heating element and released. It will be done. That is, in the aroma cartridge of the present invention, the heated aroma generating body wrapped with the heated aroma generating base material made of non-tobacco material and an aerosol former is in contact with the mouthpiece, and the heated aroma generating body is electrically controlled. The heated aroma generating body and the outside of the mouthpiece are connected to each other in a wound state by a cartridge exterior body, in a state where the heated aroma generating body is attached so as to be in contact with the type heating body and adjacent to the mouthpiece in the longitudinal direction.

FIGS. 2 and 3 show the state in which such an aroma cartridge is attached to a heating type smoking tool for smoking, with respect to two types of heating elements. In order to clarify the characteristics of the aroma cartridge of the present invention, a mechanism for enjoying the aroma cartridge by attaching it to a heating type smoking device will be briefly explained.

FIG. 2(A) is a schematic cross-sectional view of an electrically heated smoking device (1) 11 equipped with a needle-shaped electrically controlled heating element 113 provided at the bottom of a chamber 112 housed in a casing 111. . FIG. 2(B) is a schematic cross-sectional view of the aroma cartridge 2 , in which the heated aroma generator 21 wrapped with the interior material 21-p and the mouthpiece 22 wrapped with the interior material 22-p are shown. , heating type smoking device (1) adjoining in the longitudinal direction of 11 , are wound and connected by a cartridge exterior body 23. FIG. 2C shows a state in which the smoker uses the electrically heated smoking device (1) 11 to inhale the aroma cartridge 2 . The heated aroma generating body 21 side of the aroma cartridge 2 shown in FIG. When the smoker presses a switch (not shown), the electrically controlled heating element 113 is heated in accordance with a signal from an electrical control unit (not shown), and aerosol smoke and aroma components are released from the heated aroma generator 21. , suck them. When a smoker inhales, air enters from the intake port 115 as shown by arrow W, passes through the gap between the casing 111 and the chamber 112, and is absorbed into the aerosol former and aroma components volatilized from the heated aroma generator 21. is carried to the mouthpiece 22 and sucked into the smoker's oral cavity. The smoke is cooled within the mouthpiece 22 and inhaled as an aerosol.

FIG. 3(A) is a schematic cross-sectional view of an electrically heated smoking device (2) 12 including an electrically controlled heating element 123 provided on the outer periphery of a chamber 122 housed in a casing 121. FIG. 3(B) shows a state in which a smoker inhales the aroma cartridge 2 using the electrically heated smoking device (2) 12 . When the heated aroma generating body 21 side of the aroma cartridge 2 shown in FIG. When a switch (not shown) is pressed, the electrically controlled heating element 123 is heated in accordance with a signal from the electrical control unit 1231, and aerosol smoke and aroma components are released from the heated aroma generator 21 and are sucked. When a smoker inhales, air enters through the intake hole 125 as shown by the arrow W, and the aerosol former and aroma components volatilized from the heated aroma generator 21 are carried to the mouthpiece 22, and enter the smoker's oral cavity. is attracted to. The smoke is cooled within the mouthpiece 22 and inhaled as an aerosol.

In this type of smoking, aroma cartridges made only of non-tobacco materials do not generate substances harmful to the human body, tar, or nicotine, and are suitable for drinks such as coffee, cola, Red Bull, chocolate, vanilla, cream, etc. It has the advantage of being able to enjoy a variety of flavors, such as desserts, fruits such as oranges, lemons, and melons, and refreshing agents such as menthol, mint, and herbs. Problems arise due to the use of a wide variety of non-tobacco materials for release.

In the case of an aerosol-forming body containing tobacco material, the tobacco fibers maintain their lumpy state and prevent the tobacco material from falling off and fusing. In order to stably maintain the bulk state of the generation base material, it is necessary to incorporate a large amount of a binder or the like that functions as a fiber. Therefore, the density of the heated aroma-generating base material increases, the gas flow path is closed, and it becomes difficult to suction the suction components, resulting in a decrease in the amount of suction.

In addition, since aerosol formers are made of glycerin, propylene glycol, etc. that are liquid at room temperature, the more binder there is, the more the heated aroma-generating substrate bleeds out over time, causing the heated aroma-generating substrates to fuse together. do. Therefore, the gas flow path is closed, making it difficult to suction the aroma components, and as a result, the amount of suction decreases. In addition, when such fusion occurs, it becomes difficult to insert the heating element into the heated aroma-generating substrate, and the heating element may be damaged.

On the other hand, if the amount of binder added is reduced and the gas flow path is ensured, non-tobacco materials may fall off and dust may be generated, making it difficult to maintain the shape of the aroma cartridge firmly, making it difficult to insert it into the heating element. If you do so, it may be destroyed. There are also cases where these are sucked into the oral cavity.

The present invention aims to provide means for solving these problems. That is, a means is provided for securing a gas flow path and preventing a decrease in the amount of suction. Note that solutions that involve significantly changing the composition or blending ratio of the heated aroma-generating base material cannot be adopted because it is necessary to maintain the generation of aerosol that becomes smoke and the generation of aroma components released from non-tobacco materials. . Therefore, the present invention provides means for solving the problem from two different aspects.

One is a physical solution that focuses on the structure of the mouthpiece that makes up the fragrance cartridge and has a large effect on the amount of suction. The other is a chemical solution that focuses on the manufacturing method [equipment] of the heated aroma-generating substrate and its filling state.

A physical solution to the former is the provision of an aroma cartridge with a suction optimization means in the mouthpiece that improves the amount of suction, and by trapping non-tobacco materials and dust on the heated aroma generator. It is an object of the present invention to provide an aroma cartridge equipped with a suction optimization means that prevents a decrease in suction amount. More specifically, a filter that constitutes the mouthpiece, a support that prevents the heated aroma generator that constitutes the mouthpiece from moving toward the mouthpiece, and a suction optimization means for the mouthpiece, respectively. To provide an aroma cartridge equipped with a cavity that improves the amount of suction by expanding the gas flow path, a shape reinforcing member that prevents a decrease in the amount of suction due to deformation, and a heat insulating material that prevents damage to joints due to heat diffusion. It is. Another object of the present invention is to provide an aroma cartridge in which a lid material and/or a partition material for preventing and trapping falling objects such as non-tobacco materials and dust are provided as suction optimization means for a heated aroma generator.

A chemical solution to the latter is to provide the heated aroma generator with a scent cartridge with a gas production sustaining material that does not reduce suction. More specifically, a heated aroma-generating base material whose internal structure has been improved by a manufacturing method [equipment] and a heated aroma-generating group whose blending amount has been optimized are added to the heated aroma-generating body as a material for maintaining gas generation. An object of the present invention is to provide an aroma cartridge equipped with a heated aroma-generating base material, inorganic particles present inside and/or on the surface of the heated aroma-generating base material, and a heated aroma-generating base material with improved filling rate.

Since these suction optimization means and gas generation maintaining material can exert sufficient effects by themselves, FIG. FIG. 33 shows the structure of an aroma cartridge that connects a mouthpiece in which a means is disposed, and a heated aroma generator in which a gas generation maintaining material is disposed and a mouse in which a suction optimization means is not disposed. The composition of the fragrance cartridge is shown, which joins the pieces. However, since higher or wider effects can be obtained by using them together, it is possible to provide aroma cartridges with an extremely wide variety of combinations of the heated aroma generator and the mouthpiece shown in FIGS. 4 and 33.

First, the suction optimization means will be explained in detail using the drawings. FIG. 5 shows a mouthpiece 221-1 configured with a single filter 221-1 that filters gas in which one cavity 221-1-c1 is formed and a heated aroma generator 21 according to an embodiment of the present invention. are adjacent to each other, and are joined and wrapped in the cartridge exterior body 23.The cavity 221-1-c1 is located on the heated aroma generating body 21 side in the longitudinal direction of the filter 221-1. A schematic diagram showing an aroma cartridge 2-1 arranged in a filter 221-1 at the end of the filter 221-1 so that the center axes of the right circular cylinders of the filter 221-1 and the cavity 221-1-c1 are approximately the same. It is a diagram. For example, as shown in FIGS. 2 and 3, the outer diameters of the aroma cartridge, the heated aroma generator, and the mouthpiece are determined by the heated smoking devices (1) 11 and (2) 12 , so they should be set appropriately. However, in the following, the outer diameter j and length k of the aroma cartridge are 6.9 mm and 45 mm, respectively, the length a of the heated aroma generator is 12 mm, and the length m (= f) was set to 33 mm.

As for the size of the cavity, the longer and thicker it is, the more the suction amount can be increased, but due to the problem of the strength of the mouthpiece, the length c1, inner diameter b1, and surface area should be 10 to 25 mm and 1 to 25 mm, respectively. 4 mm, preferably 34.54 to 326.54 mm ² . In one embodiment of FIG. 5, a cavity is formed in the shape of a right circular column with a length c1 of 20 mm and an inner diameter of 3 mm. Moreover, although the most preferable shape of the cavity is a right cylindrical cavity, it may also be an oblique cylindrical shape, and is not limited thereto. Any hole that does not penetrate the filter may be used, but in consideration of uniform gas suction into the oral cavity and workability, it is preferable to have a symmetrical shape around the central axis of the filter, such as a triangular prism, square prism, or pentagonal shape. Preferred are columnar shapes such as columnar shapes, and conical shapes such as conical shapes (FIG. 9), triangular pyramidal shapes, square pyramidal shapes, and pentagonal pyramidal shapes.

Furthermore, although the cavity in FIG. 5 is formed at the end of the filter on the heated aroma generator side in the longitudinal direction, it may be provided at the end opposite to this end.

FIG. 6 shows a mouthpiece 221-2 configured with a single filter 221-2 that filters gas in which two cavities 221-2-c2 and 221-2-c3 are formed, according to an embodiment of the present invention. This is an aroma cartridge 2-2 in which heated aroma generators 21 are adjacent to each other, and these are joined and wrapped in a cartridge exterior body 23, and the cavities 221-2-c2 and 221-2-c3 are connected to the filter 221- The right circular cylinders of the filter 221-2 and the cavities 221-2-c2 and 221-2-c3 are arranged in the filter 221-2 at both ends of the filter 221-2 in the longitudinal direction so that the central axes o thereof are substantially the same. FIG. 2 is a schematic diagram showing an aroma cartridge 2-2 . The shape of the cavity can increase the amount of suction as it becomes longer and thicker, but since there is a problem with the strength of the mouthpiece, the lengths c2 and c3 should be 5 to 15 mm, and the outer diameter b2 and b3 are preferably 1 to 3.5 mm, and the total surface area is preferably 34.54 to 326.54 mm ² . The shape is as described in the explanation of FIG.

FIG. 21 is a schematic diagram showing the aroma cartridge 2-15, in which a cooling member is interposed between the reinforcing support member shown in FIGS. 16 to 19 and the filter in which the cavity described in FIGS. 5 to 10 is formed. An example of an aroma cartridge in which a mouthpiece is connected to a heated aroma body is shown. A reinforcing support member 2261 having shape reinforcing members 2261-s3 and 2261-s4 that prevent the adjacent heated aroma generating bodies 21 from moving toward the mouthpiece 226, and a cooling member 2261 that cools the gas from the heated aroma generating bodies 21.

It is preferable. Therefore, the length s of the heat insulating member depends on the material used, but a length of about 1 to 5 mm is sufficient.

Next, using drawings, we will explain, using drawings, the lid and partition materials that function as a suction optimization means to prevent an extreme drop in suction amount caused by clogging of the gaps in the filter and cooling member due to falling objects such as non-tobacco materials and dust. do.

FIG. 24 is a partial schematic diagram of a heated aroma generator of an aroma cartridge according to an embodiment of the present invention. The suction optimization means here includes a lid member 211 disposed at one end of the aroma cartridge of both ends of the heated aroma generator, and a lid member 211 disposed at the other end of the heated aroma generator.

Furthermore, it is possible to prevent the generation of fallen objects, dust, etc. that would occur when the aroma cartridge is stuck into a needle-shaped heating element.

In the above, physical solution means for improving the structure in order to ensure the amount of gas suctioned when smoking an aromatic cartridge has been specifically explained using the drawings. Hereinafter, a gas generation sustaining material that solves the problem of a reduction in the amount of gas suctioned and is provided in a heated aroma generator will be described with reference to the drawings. Conventional heated aroma generators have a problem in that the amount of gas released decreases over time, resulting in a decrease in the amount of gas suctioned during smoking. The aroma cartridge of the present invention includes a heated aroma-generating base material constituting a heated aroma-generating body, to which a chemical solution has been applied as a gas generation sustaining material that prevents a reduction in the amount of gas suctioned.

First, FIG. 25 shows a schematic diagram (A) of a heated aroma-generating sheet constituting a heated aroma-generating body according to an embodiment of the present invention, and a heated aroma-generating sheet according to an embodiment of the present invention. A schematic diagram (B) of the heated aroma-generating filling that constitutes the body is shown.

The heated aroma-generating base material is manufactured by various manufacturing processes [means], but is ultimately wrapped as a sheet or a filler to become the heated aroma-generating base material. As shown in Figures 2 and 3, the longitudinal direction of heating type smoking implements (1) 11 and (2) 12 corresponds to the length z direction, and they are cut to length z according to the heating type smoking implement. However, it has an appropriate width w and thickness y as a material that sustains gas production. Here, as an example, using FIG. 25, dimensions corresponding to the heated aroma generating body explained in FIG. 5 are shown. The longitudinal direction of the aroma cartridge corresponds to the length z direction, and the heated aroma generating base material is wrapped in paper in this direction to form the heated aroma generating body. The heated aroma generating sheet (A) included in the heated aroma generator has a length z of 12 mm, a width w and a thickness y of 60 to 90 mm and 0.1 to 1 mm, respectively. A range of 0 mm is preferable. The heated aroma-generating filling (B) has a length z of 12 mm, a width x and a thickness y of 1.0 to 2.0 mm, and a thickness of 0.1 to 1.0 mm, respectively.

FIG. 26 (A-2) shows a heated aroma generating body in which one heated aroma generating sheet of ) is rolled up and wrapped with the heated aroma generating body interior material 21-p. Further, FIG. 26(B) shows a heated aroma generating body in which 50 heated aroma generating fillers are wrapped with a heated aroma generating body interior material 21-p. These outer diameters are also set appropriately depending on the heating type smoking device (1) 11 and (2) 12 , but if it is 6.9 mm, which corresponds to the heated aroma generator explained in FIG. , the filling rate falls within 60-90%. In particular, when the filling rate is 60 to 73%, it has not been observed that the heated aroma-generating substrate undergoes severe fusion over time. This filling rate is adjusted by the width w of the heated aroma-generating sheet and the number of heated aroma-generating fillers, and is not limited to this when a gas generation sustaining material is present.

In the following, we will discuss gas generation sustaining materials that have the function of preventing a decrease in the amount of gas released by heated aroma generators, which is closely related to the decrease in the amount of gas inhaled during smoking, and ensuring the amount of gas inhaled. The heated aroma-generating base material to which this solution has been applied will be specifically explained using the drawings. The aroma cartridge of the present invention includes a heated aroma generating base material to which this chemical solution has been applied as a material for maintaining gas production in a heated aroma generating body.

There are various methods [apparatuses] for producing conventional heated aroma-generating substrates, and one example is shown in FIG. 33. The process [means] of preparing non-tobacco materials by dry-mixing after drying and crushing non-tobacco materials, as well as aerosol formers, binders, anti-stick agents, fragrances, non-tobacco extracts, antibacterial preservatives, etc. A step [means] of preparing the selected material, a step [means] of preparing pure water and alcohol, a wet mixing step [means] of mixing these prepared materials all at once, and a wet mixing step [means] of preparing the selected materials. A papermaking process [means] that produces a water-containing sheet from the produced slurry, a forming process [means] that produces a sheet by compressing or casting the paper-made water-containing sheet, and drying the sheet produced in the forming process [means]. It is manufactured from a step [means] and a sheet processing step [means] of cutting or bending a dried heated aroma-generating sheet.

As a specific example, (Production Example 1) is shown.

(Manufacturing example 1)
The following pulverized material was put into a dry mixer as a non-tobacco material, and dry mixed for 5 minutes.
Dry pulverized black tea leaves 100 parts by mass Dry pulverized leguminous licorice 20 parts by mass Dry pulverized lotus leaves 10 parts by mass

The above dry mixture and the following materials were placed in a wet mixer and wet mixed for 15 minutes.
Polypropylene glycol 25 parts by mass Glycerin 25 parts by mass Carboxymethyl cellulose sodium salt 5 parts by mass Menthol 3 parts by mass Ethanol 3 parts by mass Pure water 200 parts by mass

In the step [means] of forming a sheet from the slurry thus obtained, a specified amount of the slurry was put into a frame equipped with a suitable screen to prepare a water-containing sheet. At this time, in this manufacturing example, the water-containing sheet has a water content of approximately 95, assuming that the water content of the slurry is 100.

Subsequently, the above-mentioned water-containing sheet is passed through a press roll with a predetermined clearance three times to perform molding, and then, the above-mentioned pure water equivalent to 7 parts by mass is added to 100 parts by mass of the above-mentioned water-containing sheet that has been passed three times. It was added to the water-containing sheet and passed through the press roll 5 times.

Further, the formed water-containing sheet obtained as described above was dried for 300 minutes in an environment of 35° C. to produce a heated aroma-generating sheet having a water content of 20% by mass. Regarding the drying temperature, it is preferable to set it to less than 50°C in order to maintain the flavor. More preferably it is less than 45°C, and even more preferably less than 40°C. Although the thickness of the sheet is adjusted as appropriate, in this manufacturing example, the thickness was 0.5 mm. This sheet was cut into a rectangular heated aroma-generating sheet with a length of 240 mm and a width of 75 mm, and a heated aroma-generating filling with a length of 240 mm and a width of 1.5 mm. Note that the length direction of the sheet obtained by cutting the heated aroma-generating sheet and the filler was parallel to the rotation axis of the roll, and the width direction was the rotation direction of the roll.

One heated aroma-generating sheet and 50 heated aroma-generating fillers thus produced were each wrapped and then cut to a length of 12 mm, as shown in FIG. 26 (A-1). And a heated aroma generator as shown in FIG. 26(B) was produced. Then, an aroma cartridge of the type shown in FIG. 13, in which a heated aroma generator is joined to a mouthpiece equipped with a support member and a filter, was produced. As a support member, a PE tube having a cylinder having an outer diameter of 6.9 mm and a through hole having an inner diameter of 4.0 mm was used. The filter used was a 23 mm long filter made of acetyl cellulose fibers formed into a cylindrical shape and wrapped with paper having a basis weight of 34 g/m ² . The cartridge exterior body was formed by wrapping paper with a basis weight of 38 g/m ² two and a half times so as to have an inner diameter of 6.9 mm, and gluing the paper. In addition, if the cartridge exterior body is a paper tube formed by wrapping ^two and a half turns of paper with a basis weight of 32 to 45 g/m2, the heated aroma generating body part can be used as a heating type smoking tool. It is suitable as an aroma cartridge to be used by inserting it into a heating element. Then, a supporting member and a filter are inserted from one end of the cartridge exterior body to form a mouthpiece, and a heated aroma generating body is inserted from the other end, and the base weight is 40 g/m ² so as to overlap with the mouthpiece part. A fragrance cartridge was made by wrapping the paper in the container. However, in order to clarify the influence of the manufacturing method [equipment] on the heated aroma-generating base material, that is, the difference in the function of the gas generation sustaining material, the filter is a filter that does not have a cavity, which is a means of optimizing suction. It was used.

The heated aroma generator and aroma cartridge thus produced were evaluated as follows.

≪Rating 1≫
The prepared aroma cartridge was packed into a paper box with a long side of 70 mm, a short side of 14 mm, and a height of 45 mm, with the heated aroma generator facing toward the bottom. The thus prepared box containing the aroma cartridge was left in a plastic bag for two weeks in an environment of 40°C. Thereafter, the samples were taken out and left in an environment of normal temperature and humidity for one day, and the following evaluations were performed. Remove the fillings from the heated aroma generator and check whether they have solidified. At the same time, five subjects were asked to smoke, and a sensory evaluation of the amount of inhalation and flavor was conducted.
Rank A: Items that can be loosened when taken out with tweezers
Items that can be felt by 4 or more people in terms of suction amount and flavor. Rank B: Items that can be loosened by pressing with tweezers.
The amount of suction and flavor can be felt by two or more people. Rank C: Even if you press it with tweezers, lumps remain.
Items that no one can sense in terms of suction amount or flavor. Items with rank C are items that are likely to be difficult to insert into the heating element of a heated smoking device due to long-term storage.

The aroma cartridge produced in (Manufacturing Example 1) was evaluated as rank C, and the heated aroma generating sheet and the heated aroma filling were fused over time, and the amount of gas released during smoking, that is, the gas suction As the amount decreased, the flavor also deteriorated, and it did not function as a material for sustaining gas production of the aromatic substance to be heated.

This problem was solved by improving the manufacturing method [equipment]. This manufacturing method [apparatus] is characterized in that, as shown in FIG. 27, a second wet mixing process [means] is introduced as a manufacturing process [means]. As is clear from the figure, there is a dry mixing process [means] Z1 for mixing dried and crushed non-tobacco materials, a non-tobacco material produced in the dry mixing process [means], an aerosol former, a binder or a thickener. A first wet mixing step of mixing the alcohol and pure water mixture with a material selected from agent, crosslinked PVP, fragrance, non-tobacco extract, β-cyclodextrin, microcrystalline cellulose, and antibacterial preservative. A slurry containing non-tobacco materials, etc. by further adding pure water and/or alcohol to the alcohol and pure water mixture containing non-tobacco materials, etc. produced by M2 and the first wet mixing step [means] a second wet mixing process [means] M3 for producing a water-containing sheet; a papermaking process [means] S1 for producing a water-containing sheet from the slurry produced in the second wet-mixing process [means]; A sheet forming process [means] S2 for processing the sheet into a sheet, a drying process [means] S3 for drying the sheet produced in the sheet forming process [means] to produce a heated aroma-generating sheet, and cutting the heated aroma-generating sheet. Alternatively, the heated aroma-generating base material is manufactured from the sheet processing step [means] H1 of folding.

As a specific example, (Manufacturing Example 2) is shown.

(Manufacturing example 2)
Black tea leaves are dried at 70° C. to a moisture content of 2% by mass, and then crushed. Similarly, legumes such as licorice, lotus leaves, and ginseng are dried and ground. Note that the drying temperature is preferably 60°C to 80°C or lower. Within this range, it is easy to reach the desired moisture content while avoiding dissipation of the required flavor components. Note that when the temperature is 65°C or higher, it is easier to reach the desired moisture content, and when the temperature is 75°C or lower, it is possible to further prevent the necessary aroma components from dissipating.

Note that the moisture content after pulverization is preferably 5% by mass or less. In this way, it becomes easier to form a slurry in the subsequent step [means]. More preferably, it is 3% by mass or less. Further, it is preferable that the water content is 0.1% by mass or more, since it is possible to maintain good affinity with water and the like.

The thus dried and pulverized material that passed through an 80-mesh sieve was used as a non-tobacco material, and the following blending amounts were placed in a dry mixer and dry mixed for 5 minutes.
Dry pulverized black tea leaves 100 parts by mass Dry pulverized legumes 20 parts by mass Dry pulverized lotus leaves 10 parts Dried pulverized ginseng 5 parts by mass

The above dry mixture and the following materials were put into a wet mixer, and first wet mixing was performed for 15 minutes.
Polypropylene glycol 30 parts by mass Glycerin 20 parts by mass Carboxymethylcellulose sodium salt 5 parts by mass Menthol 3 parts by mass Ethanol 3 parts by mass Pure water 20 parts by mass

Next, 180 parts by mass of pure water and 10 parts by mass of ethanol are additionally charged into the wet mixer containing the slurry, and second wet mixing is performed for 10 minutes. The reason why ethanol was added here is that the state of dispersion of the dried pulverized product in polypropylene glycol and glycerin can be greatly improved. The alcohol is not limited to ethanol as long as it is a lower monoalcohol. The amount of such lower monoalcohol added is preferably 0.1 to 10 parts by weight based on 100 parts by weight of the dry pulverized product. When the amount is 0.1 parts by mass or more, the above-mentioned dispersion state is improved, and when it is 10 parts by mass or less, the residual of lower monoalcohol can be suppressed. This effect is more pronounced when the amount is 0.5 to 5 parts by mass.

The reason why pure water is added first to form a mixture is that by dispersing the above mixture in advance and then diluting and mixing with additional water, a slurry with good dispersibility can be obtained. It is also preferable to add water in multiple batches. When adding water in multiple batches, it is preferable to use a combination of reducing the amount of water added before and increasing the amount of water added later. This is because the dispersibility is improved to a high degree when water is added first, and when the amount of water added later is increased, a uniform slurry is obtained.

In the step [means] of forming a sheet from the slurry obtained as described above, a specified amount of the slurry was poured into a frame equipped with an appropriate screen to prepare a water-containing sheet. At this time, in this example, the water-containing sheet has a water content of approximately 95, assuming that the water content of the slurry is 100.

Subsequently, the above-mentioned water-containing sheet is passed through a press roll with a predetermined clearance three times to perform molding, and then, the above-mentioned water-containing sheet is mixed with water in an amount equivalent to 7 parts by mass per 100 parts by mass of the water-containing sheet that has been passed through the water-containing sheet three times. It was added to the sheet and passed through the press roll 5 times. Preferably, the amount of water is 2 parts by mass or more and 15 parts by mass or less with respect to 100 parts by mass of the water-containing sheet. In this way, when forming a water-containing sheet multiple times, by adding water midway through, it has the effect of making it easier to align the water contained in the water-containing sheet within a certain range, which improves the conditions for the subsequent drying process [means]. This has the effect of not only making it possible to make the products uniform, but also making it possible to make the quality of the final product consistent.

Furthermore, the molded water-containing sheet obtained as described above was dried in an environment of 35° C. for 300 minutes to produce a molded sheet for electronic cigarette filler having a water content of 20% by mass. Regarding the drying temperature, it is preferable to set it to less than 50°C in order to maintain the flavor. More preferably it is less than 45°C, and even more preferably less than 40°C. The thickness of the sheet was 0.5 mm. In order to wrap this sheet as a heated aroma generating body, the heated aroma generating sheet has a length z of 240 mm and a width x of 75 mm, and a heated aroma generating sheet with a length z of 240 mm and a width x of 1.5 mm. Cut into aroma-generating fillings.

One heated aroma-generating sheet and 50 heated aroma-generating fillers produced by this method [apparatus] were each wrapped and then cut to have a length z of 12 mm. Heated aroma generators as shown in A-1) and FIG. 26(B) were produced. Similarly to (Manufacturing Example 1), an aroma cartridge of the type shown in FIG. 13 in which a heated aroma generator is joined to a mouthpiece equipped with a support member and a filter was produced. However, in order to clarify the influence of the manufacturing method [equipment] on the heated aroma-generating base material, that is, the difference in the function of the gas generation sustaining material, the filter is a filter that does not have a cavity, which is a means of optimizing suction. It was used.

Then, similarly to the fragrance cartridge produced in (Manufacturing Example 1), <<Evaluation 1>> was performed, and a rank A result was obtained. This means that the heated aroma-generating substrate produced by this method [apparatus] has less fusion over time within the heated aroma-generating substrates and between each other, and the amount of gas released by heating is small. It is thought that there is little change in the amount of gas inhaled during smoking, and the amount of gas inhaled during smoking is maintained. That is, the heated aroma-generating substrate produced by this method [apparatus] functions as a gas generation sustaining material for the heated aroma-generating substrate.

The manufacturing method [apparatus] shown in FIG. 27 has been improved as shown in FIG. 28. The manufacturing method [apparatus] of FIG. 28 is a step of adding an aerosol former when the water content of the sheet becomes less than 50% in the sheet forming step [means] S2 in the manufacturing method [apparatus] shown in FIG. [Means] It is characterized by further adding S3. Specifically, the amount of propylene glycol in the first wet mixing in (Production Example 2) was reduced by 10 parts by mass, and a 50% ethanol solution of propylene glycol was sprayed at a temperature below 40°C to form a sheet. was allowed to absorb propylene glycol to make up for the propylene glycol reduced in the first wet mix. Here, the concentration of the alcohol solution in the aerosol former is preferably in the range of 20 to 80% from the viewpoint of the absorbency of the aerosol former and the drying property of the alcohol. If the concentration is high, it will be difficult to absorb, and if the concentration is low, it will take time for the alcohol to dry. The absorption temperature is also preferably 20 to 50°C from the viewpoint of the absorbability of the aerosol former. If the temperature is too high, the aerosol former will evaporate rapidly, and if the temperature is too low, it will be difficult to absorb.

Since the dispersion state in the second wet mixing was good, propylene glycol was quickly absorbed in this step [means]. The heated aroma generating substrate with a thickness of 0.5 mm manufactured by this method [apparatus] was also cut into the same size as (Manufacturing Example 2), a fragrance cartridge was made, and <<Evaluation 1>> was conducted. A result of rank A was obtained, and it became clear that the heated aroma-generating sheet produced by this method [apparatus] also functions as a gas generation sustaining material for the heated aroma-generating substrate.

A common improvement in the manufacturing method [apparatus] shown in FIGS. 27 and 28 is that the mixing and dispersion of the non-tobacco material and the aerosol former were improved. In view of this point, we have found a manufacturing method [apparatus] that does not go through the mixing and dispersion process [means] of non-tobacco materials and aerosol formers, which is the manufacturing process [means] for the heated aroma-generating base material shown in Figure 29. .

That is, a wet mixing step [means] M1 of producing a slurry of non-tobacco material by mixing dried and pulverized non-tobacco material with pure water to produce a sustained gas generation material; A papermaking process [means] S1 in which a water-containing sheet is produced from a slurry produced by the process, a sheet forming process [means] and S2 in which a water-containing sheet is processed into a sheet by compression or casting, and a papermaking process [means] in which a water-containing sheet is produced from a sheet forming process [means]. A drying step [means] S3 to reduce the amount of water to less than 50% by mass, and a sheet produced in the drying step [means] include an aerosol former, a binder or a thickener, a crosslinked PVP, a fragrance, a non-tobacco extract, β - Absorption and adsorption step of applying or soaking a mixture of alcohol and pure water of materials selected from cyclodextrin, microcrystalline cellulose, concentrated liquid of water discharged from the sheet forming process [means], and antibacterial preservatives. [Means] S4, a drying step of drying the sheet produced in the absorption and adsorption step [Means] to produce a heated aroma-generating sheet [Means] S5, and a sheet that cuts or bends the heated aroma-generating sheet A heated aroma-generating base material is manufactured from processing step [Means] H1.

A specific example of this manufacturing method [apparatus] is shown in (Manufacturing Example 3).

(Manufacturing example 3)
50 parts by mass of wood fibers, 50 parts by mass of dried black tea leaves, and 5000 parts by mass of water were mixed to form a slurry.

This slurry was cast to form a sheet with a thickness of 0.5 mm. The remaining water from the cast was concentrated and stored, and used in the next step [means].

The above sheet was dried, and per 100 parts by mass of the sheet,
10 parts by mass of polypropylene glycol, 20 parts by mass of glycerin, 2 parts by mass of sodium carboxymethyl cellulose, 3 parts by mass of menthol (50% ethanol solution), and 50 parts by mass of concentrated water from cast residue were added and dried to prepare a sheet.

The produced sheet was subjected to <<Evaluation 1>> by producing a heated aroma generator and an aroma cartridge using the same in the same manner as in (Manufacturing Example 2), and a rank A result was obtained. It has become clear that the heated aroma-generating sheet produced by the method [apparatus] also functions as a gas production sustaining material for the heated aroma-generating substrate.

Conventional manufacturing methods [apparatus] have been characterized by producing a heated aroma-generating sheet by producing a slurry of non-tobacco materials and papermaking, but as shown in FIG. The method [equipment] of absorbing aerosol formers, fragrances, binders, etc. into a water-containing sheet produced by paper-making from a slurry made only of tobacco materials has yielded good results, and we have now started making paper from slurries of materials with various properties. Considering that this process [means] is unreasonable, we investigated a manufacturing method [equipment] that does not require a papermaking process [means], and as a result, we discovered the method [apparatus] shown in FIG. 30. It is characterized by the application of large shear and compressive forces, such as triple rolls, to the mixture of non-tobacco materials.

That is, the non-tobacco material preparation step [Means] Z1 and 2 of drying and pulverizing non-tobacco material, and mixing at least a fragrance and/or a non-tobacco material extract and cross-linked PVP and/or β-cyclodextrin in alcohol. A flavor and/or non-tobacco extract dissolving step [Means] M1 in which flavor and/or non-tobacco extract is suspended in cross-linked PVP and/or β-cyclodextrin; and at least an aerosol former and a binder or thickener. The aerosol former dissolving step [means] M2 mixed with pure water, the material produced in the non-tobacco material preparation step [means], the material produced in the flavor and/or non-tobacco extract dissolving step [means], A wet mixing process [means] M3 that mixes the materials produced in the aerosol former melting process [means], and a sheet forming process that produces a heated aroma-generating sheet by compressing the materials produced in the wet mixing process [means]. [Means] This is a method [apparatus] for manufacturing a heated aroma-generating base material from S1 and a sheet processing step [Means] H1 in which a heated aroma-generating sheet is cut or folded.

A specific example of this manufacturing method [apparatus] is shown in (Manufacturing Example 4).

(Manufacturing example 4)
In the non-tobacco material preparation step [means] Z1 and 2 of drying and pulverizing non-tobacco material, black tea leaves are used as the non-tobacco material, and after drying in an oven at 70 ° C., using an agitation type pulverizer. A non-tobacco material having a moisture content of 2% by mass is prepared by pulverizing and passing through an 80 mesh sieve.

In the step [means] M1 of dissolving menthol, menthol, lower alcohol, and water-insoluble crosslinked polymer are weighed and mixed to dissolve menthol. After dissolving menthol in the lower alcohol, it is preferable to add and mix the water-insoluble crosslinked polymer. When menthol, a lower alcohol, and a water-insoluble crosslinked polymer are mixed, the effect of suppressing the dissipation of menthol can be obtained.

Here, menthol is not limited to those obtained from natural products, and synthetic products can also be used. Additionally, mint, mint, peppermint oil, and other materials containing menthol may be used.

The lower alcohol is a solvent that dissolves menthol, and ethyl alcohol is particularly preferably used.

The water-insoluble crosslinked polymer is intended to be a non-crosslinked polymer that is soluble in water and crosslinked so that it becomes insoluble in water and swells. Of course, it is preferable that it does not dissolve in lower alcohols but swells, and such a substance is selected. Such a water-insoluble cross-linked polymer has a hydrophilic part and a hydrophobic part, and the hydrophilic part contributes to swelling, and the hydrophilic part orients to menthol, thereby suppressing the dissipation of menthol. Conceivable. Preferred examples of the hydrophilic crosslinked polymer include crosslinked PVP, and crosslinked polysaccharides made water-insoluble by subjecting water-soluble polysaccharides to epoxy crosslinking, ester crosslinking, or ether crosslinking. In particular, when ethanol and crosslinked PVP were used together with menthol, the effect of significantly suppressing the dissipation of menthol was observed.

It is sufficient to add menthol in an amount that targets the desired flavor, but it is preferable that the menthol content in the heated aroma-generating base material is 0.1 to 10 mass, and 0.2 to 5 mass. It is more preferable that there be.

In forming the heated aroma-generating substrate, the amount of the hydrophilic crosslinked polymer added is preferably 10 to 2000 parts by weight, more preferably 50 to 600 parts by weight, based on 100 parts by weight of menthol.

In order to achieve the effect of suppressing the dissipation of menthol, the hydrophilic crosslinked polymer is preferably present in an amount of 2% by mass or more, more preferably 4% by mass or more in the heated aroma-generating base material. . By having such an amount present, long-term storage is possible while suppressing dissipation of menthol, and even after long-term storage, the refreshing feeling of menthol can be enjoyed. Further, the content of the hydrophilic crosslinked polymer in the heated aroma-generating base material is preferably 20% by mass or less, more preferably 10% by mass or less. When the amount is 10% by mass or less, it is possible to maintain the flavor caused by non-plant-derived polyphenols and the like.

The lower alcohol used is preferably 50 parts by mass or more based on 100 parts by mass of menthol. Furthermore, when the amount is 100 parts by mass or more, the hydrophilic crosslinked polymer can be sufficiently mixed while dissolving menthol. When the amount is 2000 parts by mass or less, residual lower alcohol can be reduced in the post-process [means], and an efficient manufacturing process [means] can be achieved.

From the above, as an example,
Weigh out 100 parts by mass of menthol, 200 parts by mass of ethyl alcohol, and 200 parts by mass of polyvinylpolypyrrolidone, dissolve the menthol in ethyl alcohol to obtain a menthol ethyl alcohol solution, then add crosslinked PVP to the menthol ethyl alcohol solution and mix with stirring. A menthol/ethyl alcohol/crosslinked PVP mixture was obtained.

Next, in the step [means] M2 of dissolving materials such as the aerosol former, the aerosol former, flavor additive, preservative, binder, thickener, etc. are dissolved in pure water.

Here, the aerosol formers include glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerine diacetate), triacetin (glycerine triacetate), triethylene glycol diacetate, triethyl citrate, myristic acid. Isopropyl, methyl stearate, dimethyl dodecanedioate, dimethyl tetradecanesanedionate, etc. can be used. In particular, glycerin and propylene glycol are preferably used. These are preferably used in an amount of 1 to 80% by mass, more preferably 10 to 40% by mass, based on the heated aroma-generating substrate.

Flavoring agents that add flavor are optionally used and include extracts of peppermint, cocoa, coffee, black tea, and the like.

In addition, an antibacterial food preservative can be added if necessary. As antibacterial preservatives, sorbic acid, potassium sorbate, benzoic acid, sodium benzoate, etc. can be used.

As binders or thickeners, gums such as guar gum, xanthan gum, gum arabic, and locust bean gum, modified cellulose polymers such as hydroxypropyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, methyl cellulose, and ethyl cellulose, starch, Organic acids such as alginic acid, polysaccharides such as sodium alginate, sodium carboxymethyl cellulose, caranagin, agar, and conjugate base salts of organic acids such as pectin can be used. You may use these in combination.

From these, 20% aqueous solutions of glycerin, propylene glycol, sodium carboxymethylcellulose, methylcellulose, glucomannan, and xylitol were prepared.

Next, a step [means] M3 of wet mixing the materials of each step [means] of the non-tobacco material preparation step [means] Z1 and 2, the flavor dissolving step [means] M1, and the aerosol former dissolving step [means] M2. Now, using a conventional wet mixer, the following composition was stirred for 15 minutes while applying shearing force with a stirring blade to prepare a composition for a heated aroma-generating substrate of a non-tobacco plant.
Dry and crushed black tea leaves 100 parts by mass Menthol/ethyl alcohol/crosslinked PVP 25 parts by mass Glycerin 30 parts by mass Propylene glycol 30 parts by mass Sodium carboxymethyl cellulose 4 parts by mass Methyl cellulose 15 parts by mass Xylitol aqueous solution 8 parts by mass Glucomannan 1 part by mass

In the step (means) S1 of forming the sheet, a three-roll mill was used. Three rolls of the above composition were put into a roll mill, 20 parts by mass of pure water was added while checking the condition of the sheet, and the process [means] of pressing a doctor blade against the rolls to collect a sheet was repeated 8 times, and the final A sheet-like non-tobacco plant composition was obtained. When a three-roll mill is used, the compressive force caused by being pushed between narrow rolls and the shearing force caused by the difference in roll speed are used to perform kneading, dispersion, etc., and a sheet of desired thickness can be formed using a doctor blade. It is possible to produce a more homogeneous sheet than by producing a sheet from a slurry papermaking process [means]. In addition to the three-roll mill, press rollers and presses can also be suitably used.

In the sheet forming step [means] S1, non-tobacco plants, aerosol formers, fragrances, antibacterial preservatives, binders or thickeners, water, etc. may be added as necessary.

The pure water used in the present invention is preferably sterilized or free of microorganisms, but pure water obtained by reverse osmosis membranes, ion exchange, or the like may also be used.

In this sheet forming process [means] S1, a sheet having a thickness of about 0.5 mm was formed. The thickness of the sheet may be in the range of 0.1 to 1.0 mm or 0.1 to 0.5 mm.

Subsequently, this heated aroma generating sheet with a thickness of 0.5 mm was cut into a heated aroma generating sheet and a heated aroma generating filler in the same manner as in (Production Example 2), and then processed into a heated aroma generating body. and assembled into an aromatic cartridge. Then, when <<Evaluation 1>> was similarly performed, a result of rank A was obtained, and the heated aroma-generating sheet produced by this method [apparatus] also functions as a material that sustains gas production for the heated aroma-generating substrate. It became clear that

As mentioned above, heated aroma generating substrates using non-tobacco materials have a wide variety of constituent compositions and their properties, and the non-uniformity of their mixing, dispersion, and dissolution state affects the heating aroma generation base material. It is clear that this is the cause of changes over time such as bleed-out of the aerosol former from the generating base material, which reduces the amount of gas released from the heated aroma-generating base material and reduces the amount of gas inhaled during smoking. became. Therefore, by improving the non-uniformity, it was possible to resolve the temporal change in the amount of gas suction.

Furthermore, it has been found that the cause of the problems peculiar to aroma cartridges using non-tobacco materials lies in the binder or thickener, which is one of the constituent materials of the heated aroma-generating base material using non-tobacco materials. These are added to prevent the destruction of lumps that occur due to the inability to contain a large amount of fiber, and to prevent fusion that occurs inside the heated aroma-generating substrate and between the heated aroma-generating substrates. If the amount added increases, the density of the heated aroma-generating base material increases and it is possible to maintain a lumpy state, but the heated aroma-generating base material shrinks over time and bleed-out of the aerosol former occurs. I knew it would get intense. Therefore, as a result of examining the amount of binder added, the addition method [apparatus], and the type, it was found that the heated aroma-generating base material produced by the method [apparatus] shown in FIG. 31 can solve the above problems.

That is, steps [means] Z1 and 2 of preparing dried and pulverized non-tobacco material, step [means] M1 of preparing a first binder aqueous solution by dissolving the first binder in pure water, Step of preparing materials selected from aerosol former, cross-linked PVP, fragrance, non-tobacco extract, β-cyclodextrin, microcrystalline cellulose, and antibacterial preservative [Means] The materials prepared in Z4 and 5 are A first wet mixing step [means] M1 for mixing, a curing step [means] Y1 for stabilizing the mixed liquid produced in the first wet mixing step [means], and a curing step [means] Y1 for stabilizing the mixed liquid produced in the first wet mixing step [means]. A second wet mixing step [means] M2 of mixing the second binder aqueous solution prepared in step [means] Z6 of dissolving the curing mixture and the second binder in pure water; A sheet forming process [means] S1 in which a heated aroma-generating sheet is produced by compressing the material produced in the mixing process [means], and a sheet processing process [means] H1 in which the heated aroma-generating sheet is cut or folded. The heated aroma-generating base material manufactured from the above can stably maintain a lumpy state and will not block gas flow paths. Furthermore, no fusion was observed between the heated aroma-generating substrates over time.

(Manufacturing Example 5) is shown as a specific example of this manufacturing method [apparatus].

(Manufacturing example 5)
In the process [means] Z1 of drying and pulverizing the non-tobacco plant as a raw material, it is preferable to adjust the moisture content so that the aerosol former, pure water, and other components can be easily absorbed or supported, and the drying temperature is The temperature is preferably 60 to 80°C or less. Within this range, it is easy to reach the desired moisture content while avoiding dissipation of the required flavor components. Note that when the temperature is 65°C or higher, it is easier to reach the desired moisture content, and when the temperature is 75°C or lower, it is possible to further prevent the necessary aroma components from dissipating. The moisture content after drying and pulverization is preferably 5% by mass or less, which facilitates slurry formation in the post-process [means]. More preferably, it is 3% by mass or less. However, if the water content is not 0.1% by mass or more, the affinity with water etc. will decrease. Furthermore, by providing a sieving step [means] for sieving the dry pulverized material, non-tobacco plants with a desired particle size can be introduced into the first wet mixing step [means] M3, and slurry can be easily formed. Become.

The first binder used in step [means] Z3 of preparing the first binder by dissolving it in pure water includes cellulose, konjac mannan (glucomannan), guar gum, pectin, carrageenan, tamarin seed gum, Examples include gum arabic, soybean polysaccharide, locust bean gum, karaya gum, xanthan gum, agar, cornstarch, etc., but cellulose is preferred. Regarding the viscosity, when the solution viscosity is 300 mPa·s or more, mixing with non-tobacco plants is good. Moreover, a solution viscosity of 5000 mPa·s or more is suitable for binding non-tobacco plants. The solution viscosity is the value measured by preparing a 1% aqueous solution using a Brookfield viscometer, at 10 to 30 rpm in an environment of 25°C, and when the rotor starts rotating and the displayed value becomes stable. be. Here, the measurement upper limit of the Brookfield viscometer is 100,000 mPa·s, but viscosity exceeding this upper limit also falls within the above-mentioned viscosity range.

Celluloses preferred as the first binder generally include cellulose, cellulose derivatives, and metal salts thereof, but in the present invention, water-soluble ones are particularly preferred from the viewpoint of binding non-tobacco plants. preferable. Examples of such celluloses include methylcellulose, ethylcellulose, carboxymethylcellulose, carboxyethylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, and metal salts thereof such as sodium, potassium, and calcium. Among these, metal salts of cellulose are more preferred, and carboxymethyl cellulose sodium is even more preferred.

The aerosol former used in step [means] Z4 of preparing an aerosol former includes glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), Ethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanedioate, dimethyl tetradecanesandioate, etc. can be used, but glycerin and propylene glycol are particularly preferred. These are used in an amount of 1 to 80% by mass, preferably 10 to 40% by mass, based on the composition of the heated aroma-generating base material.

In the process [means] Z5 of preparing something to be used other than the above, in order to add flavor as necessary, it has a function of retaining flavoring agents such as menthol, peppermint, cocoa, coffee, and tea extracts. Antibacterial preservatives for food such as cross-linked PVP, β-cyclodextrin, microcrystalline cellulose with peelability and moldability from molds, etc., sorbic acid for storage stability, potassium sorbate, benzoic acid, sodium benzoate, etc. Agents etc. can be added.

The materials prepared as described above are mixed in a first wet mixing step [means] M1. The mixer does not require a special one; for example, it may be a mixer that mixes the materials in the mixing tank while applying shearing force with stirring blades, or kneads the materials using a roll mill, kneader, or extruder. It is also possible to further intensify the mixing. The mixing temperature in this step [means] is preferably 40°C or lower, more preferably 30°C or lower, and even more preferably maintained at about 25°C. This is because if excessive heat is applied during mixing, the aroma components may dissipate. Therefore, it is necessary to control the temperature of the mixing tank.

The first mixture produced in the first wet mixing step [means] M1 is preferably subjected to a curing step [means] Y1 in which it is left at a predetermined temperature and for a predetermined time, but this is not an essential step [means]. However, the binder must be added separately to the first mixing step [means] and the second mixing step [means]. In this way, both the non-tobacco material mixture that does not go through the curing process [means] Y1 in which the binder is added in portions and the curing mixture that goes through the curing process [means] Y1 process the heated aroma-generating base material into an aroma cartridge. For example, when smoking is evaluated using the heated smoking device shown in FIG. 2, both the initial suction amount and flavor are improved. Even when storage stability was evaluated in a high-temperature and humid environment, there was no fusion within the heated aroma-generating substrate and between the heated aroma-generating substrates. There is no change over time in the amount released, that is, the amount inhaled, and no change in flavor is observed. In particular, it is preferable to use tea as the non-tobacco material because the effect is remarkable. However, the curing process [means] Y1 can further enhance these effects.

The temperature of the curing step [means] Y1 is preferably 15 to 30°C, more preferably 18 to 24°C. When the temperature is 15°C or higher, the above-mentioned flavor improvement effect increases, and when the temperature is 30°C or lower, the above-mentioned changes in the amount of suction over time and changes in flavor are suppressed, and the improvement in flavor over time is maintained. It is. These effects are more pronounced at 18-24°C. Further, the time of the curing step [means] Y1 is preferably 72 to 336 hours, more preferably 96 to 192 hours. This is because when the time is 72 hours or more, the flavor is improved, and when the time is 336 hours or less, the change in the amount of suction and the change in flavor over time are suppressed, and the improvement in flavor over time is maintained. These effects are more pronounced between 96 and 192 hours. It is preferable that the curing is performed while the mixture after the first wet mixing is sealed. This is to prevent the flavor from dissipating.

The mixture immediately after the first wet mixing and the mixture cured after the first wet process [means] are input to the second wet mixing process [means] M2. The second wet mixing step [means] M2 is characterized in that a second binder is added and mixed. As described above, the effect of adding the first binder and the second binder separately is that in addition to improving the initial suction amount and flavor, and reducing the change in suction amount and flavor over time, it also improves the sheet forming process [means ] H1 makes it easier to mold into a desired shape. Moreover, it is easier to mix than adding in the first step [means], the time required for the mixture to have a uniform viscosity can be shortened, and the viscosity can be easily adjusted.

Like the first binder, examples of the second binder include cellulose, konjac mannan (glucomannan), guar gum, pectin, carrageenan, tamarin seed gum, gum arabic, soybean polysaccharide, locust bean gum, karaya gum, xanthan gum, Agar, starch, cornstarch, etc. can be used, but polysaccharides other than cellulose are preferred. Regarding the viscosity, similarly to the first binder, when the solution viscosity is 300 mPa·s or more, mixing with non-tobacco plants is good. Moreover, a solution viscosity of 5000 mPa·s or more is suitable for binding non-tobacco plants. Note that this viscosity was also measured using the method [apparatus] described above. Here, the measurement upper limit of the Brookfield viscometer is 100,000 mPa·s, but viscosity exceeding this upper limit also falls within the above-mentioned viscosity range.

As the second binder, polysaccharides are preferably used. Among polysaccharides, it is particularly preferable to use polysaccharides that are water-soluble, swell with water, or gel. By using such a material, the molded heated aroma-generating base material maintains a lumpy state, improves molding processability, and prevents occurrences such as sheet breakage and non-tobacco material falling off in the sheet molding process [means] H1. Decrease. Such polysaccharides include glucomannan, guar gum, pectin, carrageenan, locust bean gum, and agar. When adding these agents, it is preferable to use them at a solution viscosity higher than that of the first binder. By using the binder in this manner, the processing suitability in the sheet forming step [means] 11 is further improved. Among them, glucomannan is most preferred.

In this second wet mixing step [means] M2, if necessary, flavorants such as menthol, peppermint, cocoa, coffee, and tea extracts, and crosslinked PVP or β-cyclodextrin having a function of retaining flavorants are used. , microcrystalline cellulose that has peelability and moldability from molds, etc., food-grade antibacterial preservatives such as sorbic acid, potassium sorbate, benzoic acid, and sodium benzoate for storage stability. ] It may be preferable to use a manufacturing method [equipment] in which the compound is prepared and added in the same manner as Z5.

When the materials prepared as described above are mixed in the second wet mixing step [means] M2, a normal wet mixer can be used as in the first wet mixing step [means] M1. For example, a mixer may be used that mixes the materials in the mixing tank while applying shearing force using stirring blades, or it is also possible to knead the materials using a roll mill, kneader, or extruder to further intensify the mixing. The mixing temperature in this step [means] is preferably 40°C or lower, more preferably 30°C or lower, and even more preferably maintained at about 25°C. This is because if excessive heat is applied during mixing, the aroma components may dissipate. Therefore, it is necessary to control the temperature of the mixing tank.

Next, the composition of the heated aroma-generating base material containing the non-tobacco material produced in the second wet mixing M2 is put into a sheet forming process [means] H1, and is formed into a desired shape. In order to use this composition as a heated aroma-generating base material, sheet forming processing such as roll forming or press forming is preferable, but the process is not limited thereto. A method [apparatus] of passing through an orifice under pressure and forming it into a rod shape, or a method [apparatus] of drying and then pulverizing it into granules may be adopted.

Here, a sheet forming process suitable for manufacturing a heated aroma-generating substrate will be described. As one method [apparatus], a three-roll mill was used to form the material into a sheet. When using a three-roll mill, it is possible to form a sheet of the desired thickness using a doctor blade while performing kneading and dispersion using the compressive force caused by being pushed between narrow rolls and the shearing force caused by the speed difference between the rolls. This is particularly preferable for sheet forming, such as the composition of the present invention, in which a wide variety of materials with different properties are mixed. Moreover, you may produce using a press roller or a press machine together. In this way, since the three-roll mill processes the material into a sheet while performing kneading and dispersion, it complements the first and second wet mixing, and can achieve a more preferable mixing and dispersion state. Therefore, when a three-roll mill is used in the second wet mixing process [means] M2, there is no difference in equipment between the second wet mixing process [means] M2 and the sheet forming process [means] H1, and they are the same. This means that mixing and shaping take place within the process.

In this way, in sheet forming using a three-roll mill, mixing and dispersion can be performed, so if necessary, non-tobacco materials, aerosol formers, binders or thickeners, fragrances, cross-linked PVP, β-cyclodextrin, It is also possible to adopt a manufacturing method [equipment] in which microcrystalline cellulose, an antibacterial preservative, pure water, etc. are also added.

In order to clarify the characteristics of the method [apparatus] for producing a heated aroma-generating base material, which consists in adding the first binder and the second binder separately, the materials used are common and , the form of the heated aroma-generating substrate was limited to a filler, and a comparative evaluation was made with a conventional manufacturing method [equipment]. The present invention will be explained with reference to manufacturing examples and examples.

(Manufacturing example A)

The obtained first mixture was put into the second wet mixing step [means] M2. While charging 100 parts by mass of the first mixture into a three-roll mill, 0.5 parts by mass of glucomannan and 20 parts by mass of water were added. Thereafter, the step [means] of pressing a doctor blade against the roll to collect a sheet-like material was repeated eight times. In such a process [means], the second wet mixing process [means] M2 and the sheet forming process [means] H1 are performed in the same device, and the first half of the mixing process is performed in the second mixing process [means] M2, The latter half of the mixing can be regarded as the sheet forming process [means] H1. Then, a sheet with a desired thickness was manufactured using a three-roll mill while also performing kneading and dispersion.

The heated aroma generating sheet produced through these steps [means] was molded to have a thickness of 0.3 mm. This sheet was cut into a rectangle measuring 150 mm long x 240 mm wide, fed to a rotary cutter, and processed into a shape with a width of 1.5 mm, a length of 240 mm, and a thickness of 0.3 mm to obtain a heated aroma-generating filling. Fifty of the fillers were bundled and aligned in the longitudinal direction, wrapped with paper having a basis weight of 34 g/m ² , and glued to form a cylindrical heated aroma-generating product. The inner diameter of this workpiece was 6.9 mm. Furthermore, this was cut into a length of 12.0 mm to obtain a heated aroma generator. The mass of this heated aroma generator was 0.29 g, and the volume filling ratio of the filler to its volume was 0.60. Note that the vertical direction of the rectangular shape into which the heated aroma-generating sheet was cut was parallel to the rotational axis of the roll, and the horizontal direction thereof was defined as the rotational direction of the roll (the same applies hereinafter).

The viscosity of the aqueous solution of sodium carboxymethyl cellulose used in this production example was 650 mPa·s (Brookfield viscometer, 1% aqueous solution, 25°C), and the viscosity of the aqueous solution of glucomannan, a polysaccharide, was 44,000 mPa·s (Brookfield viscometer, 1% aqueous solution, 25°C). Field viscometer, 1% aqueous solution, 25°C).

(Manufacturing example B)
A first mixture was produced in the same manner as in (Production Example A) up to the first wet mixing step [Means] M1. The first mixture was placed in a polyethylene bag, sealed, and cured at a temperature of 20° C. for 6 days (144 hours) to prepare a cured mixture. After the curing process [means] Y1, the apparent volume was approximately 1.5 times larger. Curing process [Measures] When the second curing mixture after Y1 was checked, it was observed that there was less release of crushed tea products compared to before curing, and curing leads to a stable and uniformly dispersed state. it is conceivable that. The mixture prepared in the curing step [means] Y1 was put into the second wet mixing step [means] M2, and a heated aroma generator was produced in the same manner as in (Production Example A).

(Manufacturing example C)
In the same manner as in (Production Example B), the curing mixture was put into the second wet mixing process [means] M2, and a heated aroma-generating sheet was produced through the sheet forming process [means] H1. In the second wet mixing step [means] and the sheet forming step [means] H1, processing conditions were changed and the sheet was formed to a thickness of 0.1 mm to produce a heated aroma-generating sheet. This sheet was cut into a rectangle measuring 150 mm long x 240 mm wide, and fed to a rotary cutter to obtain a heated aroma-generating filling having a width of 1.0 mm, a length of 240 mm, and a thickness of 0.1 mm. These 225 fillers were bundled and aligned in the longitudinal direction, wrapped with paper having a basis weight of 34 g/m ² , and glued to form a cylindrical heated aroma-generating product. The inner diameter of this workpiece was 6.9 mm. Furthermore, this was cut into a length of 12.0 mm to obtain a heated aroma generator. The mass of this heated aroma generator was 0.29 g, and the volume filling ratio of the filler to its volume was 0.60.

(Manufacturing example D)
In the same manner as in (Production Example B), the curing mixture was put into the second wet mixing process [means] M2, and a heated aroma-generating sheet was produced through the sheet forming process [means] H1. In the second wet mixing step [means] and the sheet forming step [means] H1, processing conditions were changed and the sheet was formed to a thickness of 0.5 mm to produce a heated aroma-generating sheet. The heated aroma-generating sheet was cut into a rectangle measuring 150 mm long x 240 mm wide, and fed to a rotary cutter to form a heated aroma-generating filling having a width of 1.0 mm, a length of 240 mm, and a thickness of 0.5 mm. . These 225 fillers were bundled and aligned in the longitudinal direction, wrapped with paper having a basis weight of 34 g/m ² , and glued to form a cylindrical heated aroma-generating product. The inner diameter of this workpiece was 6.9 mm. Furthermore, this was cut into a length of 12.0 mm to obtain a heated aroma generator. The mass of this heated aroma generator was 0.29 g, and the volume filling ratio of the filler to its volume was 0.60.

For comparison, a heated aroma generator was prepared by adding the first binder, methylcellulose and carboxymethylcellulose, and the second binder, glucomannan, all at once.

(Comparative manufacturing example)
100 parts by mass of xylitol and 400 parts by mass of water were stirred and mixed to obtain a xylitol/aqueous solution.

Next, the black tea leaves were dried at 70°C, crushed, and passed through an 80 mesh sieve. The water content was 2% by mass. Similarly, dried Amachazuru was crushed and passed through an 80 mesh sieve.

Dry and ground black tea leaves 80 parts Dry and ground Amachazuru 20 parts Methyl cellulose 15 parts Glycerin 30 parts Propylene glycol 30 parts Sodium carboxymethyl cellulose 4 parts Xylitol/aqueous solution 8 parts Glucomannan 0.5 parts by weight 20 parts by mass of water were put into a mixer and mixed for 15 minutes to obtain a mixture containing all the ingredients including glucomannan.

The mixture thus prepared was mixed in a three-roll mill, and the process [means] of pressing a doctor blade against the rolls to collect a sheet-like material was repeated eight times. A heated aroma-generating sheet was produced. However, there were difficulties in forming a sheet when molding using a three-roll mill. In addition, although it was made into a sheet, it was not possible to measure the evaluation A.

The heated aroma-generating sheet produced in this way is cut into a rectangle measuring 150 mm long x 240 mm wide, and fed to a rotary cutter to form a sheet with a width of 1.5 mm, a length of 240 mm, and a thickness of 0.3 mm. A processed heated aroma-generating filling was obtained. Fifty of the fillers were bundled and aligned in the longitudinal direction, wrapped with paper having a basis weight of 34 g/m ² , and glued to form a cylindrical heated aroma-generating product. The inner diameter of this workpiece was 6.9 mm. Furthermore, this was cut into a length of 12.0 mm to obtain a heated aroma generator. The mass of this heated aroma generator was 0.29 g, and the volume filling ratio of the filling to the volume was 0.60.

(Example A)
Using the heated aroma generator produced in (Manufacturing Example A), an aroma cartridge of the type shown in FIG. 13 in which the heated aroma generator is joined to a mouthpiece equipped with a support member and a filter was produced. As a support member, a PE tube having a cylinder having an outer diameter of 6.9 mm and a through hole having an inner diameter of 4.0 mm was used. The filter used was a 23 mm long filter made of acetyl cellulose fibers formed into a cylindrical shape and wrapped with paper having a basis weight of 34 g/m ² . The cartridge exterior body was formed by wrapping paper with a basis weight of 38 g/m ² two and a half times so as to have an inner diameter of 6.9 mm, and gluing the paper. In addition, if the cartridge exterior body is a paper tube formed by wrapping ^two and a half turns of paper with a basis weight of 32 to 45 g/m2, the heated aroma generating body part can be used as a heating type smoking tool. It is suitable as an aroma cartridge to be used by inserting it into a heating element. Then, a supporting member and a filter are inserted from one end of the cartridge exterior body to form a mouthpiece, and a heated aroma generating body is inserted from the other end, and the base weight is 40 g/m ² so as to overlap with the mouthpiece part. A fragrance cartridge was made by wrapping the paper in the container. However, in order to clarify the influence of the manufacturing method [equipment] on the heated aroma-generating base material, that is, the difference in the function of the gas generation sustaining material, the filter is a filter that does not have a cavity, which is a means of optimizing suction. It was used.

(Example B)
A fragrance cartridge was produced in the same manner as in (Example A) except that the heated aroma generator produced in (Production Example B) was used.

(Example C)
A fragrance cartridge was produced in the same manner as in (Example A) except that the heated aroma generator produced in (Production Example C) was used.

(Example D)
A fragrance cartridge was produced in the same manner as in (Example A) except that the heated aroma generator produced in (Production Example D) was used.

(Comparative example)
A fragrance cartridge was produced in the same manner as in (Example A) except that the heated aroma generator produced in (Comparative Production Example) was used. However, when producing the aroma cartridge, the heated aroma-generating filling was too soft, making it difficult to produce.

The heated aroma generating sheet and aroma cartridge produced as described above were evaluated as follows. In addition to the evaluation below, <<Evaluation 1>> was also conducted.

≪Rating A≫
A tensile strength test was conducted on the heated aroma-generating sheet. A commonly used tensile strength testing machine was used for the tensile strength test. The sample used was a heated aroma generating sheet cut into a width of 10.0 cm and a length of 22.0 cm, and the tensile strength test was conducted at a distance between clamps of 20.0 cm and a crosshead speed of 10 cm/min. The test environment was a room temperature of 20° C. and a humidity of 50%. The heated aroma generating sheets produced by each manufacturing method [apparatus] were evaluated by comparing the breaking strength, and the breaking strength was 3.9 N/mm ² or more, preferably 5.0 N/mm ² or more. It has been found that it is preferable overall for molding processing, aroma cartridge production, initial suction amount, initial flavor, and changes in suction amount and flavor over time.

≪Rating B≫
The heating type smoking device used was IQOS (registered trademark), which is a heating type electronic cigarette device manufactured by Philip Morris Co., Ltd., as shown in FIG. 2(A). This heating element has a width of 4.5 mm, a length to the tip of 12 mm, and a thickness of 0.4 mm. Since the inner diameter of the chamber is 7 mm, the outer diameter of the aroma cartridge is set to 6.9 mm so that the aroma cartridge can be inserted therein without any gaps. The heating element generates heat at approximately 350° C. using electric power supplied from a battery provided within the heated electronic cigarette body. And with the built-in control system, with a conventional e-cigarette cartridge, one cigarette is consumed after 14 puffs. Note that when the smoking cigarette cartridge of this embodiment is inserted, the length of the aromatic cartridge portion that appears outward from the downstream side of the electronic cigarette device main body is about 20 mm. Then, the aroma cartridges manufactured in the present example and the comparative example were inserted into the chamber of an electronic cigarette device, and a smoking test was conducted. Both the amount of suction and the flavor were sensory evaluations of the oral cavity during smoking, and in particular, the flavor was evaluated for the scent of tea immediately after the aroma cartridge was prepared and after being left for <<Evaluation 1>>. Note that the sensory test was conducted with five subjects. The evaluation criteria are as follows.
Rank A: Smoking is at a level where there is sufficient suction volume, there is no resistance to suction, and the aroma of tea can be enjoyed.
Rank B: When smoking, the amount of suction is insufficient, there is resistance to suction, and the tea aroma is at an unsatisfactory level.

≪Rating C≫
The shedding of the filling after smoking was evaluated. The evaluation method [apparatus] was to orient the heated aroma generating body side of the aroma cartridge vertically downward and observe whether or not the heated aroma generating filler had fallen. The evaluation criteria are as follows.
Rank A: No fallen objects found Rank B: Some of the filling material has fallen

The test results are shown in Table 1. As is clear from Table 1, the binder has no effect on molding, aroma cartridge production, initial suction amount and flavor, changes in suction amount and flavor over time, and fusion of the heated aroma-generating filler over time. The effect of adding in portions has been recognized, and curing can further enhance the effect. Therefore, it is clear that the heated aroma-generating base material to which the binder is added in portions and the heated aroma-generating base material prepared by further performing the curing process [means] function as a material that sustains gas generation for the aroma cartridge. be.

As mentioned above, the manufacturing method [device] affects the internal structure of the heated aroma-generating base material, and the gas generation of the aroma cartridge produced using the heated aroma-generating base material produced by the appropriate manufacturing method [device] is sustained. It was confirmed that it functions as a material. In the present invention, we have further discovered a material that functions as a sustained gas production material. It is an inorganic particle.

The effects of inorganic particles will be explained with specific examples. For this purpose, we adopted (Production Example 1) as a conventional production method [equipment], and investigated the effects of various inorganic and The influence of particles was evaluated as follows.

In accordance with (Manufacturing Example 1), the production of the heated aroma generating body and the assembly of the fragrance cartridge are performed, but in this example, as shown in the spraying step [means] H2 in FIG. The heated aroma generating sheet was cut into pieces of length 12 mm x width 1.5 mm (thickness 0.5 mm) to prepare heated aroma generating fillers, after which a predetermined amount of various inorganic particles were added to generate heated aroma. Added a process [means] of spraying and sprinkling so that it adheres uniformly to the surface of the generated filling. The purpose of such a process [means] is to uniformly adhere inorganic particles to the surface of the heated aroma-generating filling. In addition, in this step [means], in order to confirm that inorganic particles were attached to the surface of the heated aroma-generating filling, the surface was observed using a microscope. Next, the heated aroma-emitting filler to which the inorganic particles were attached was processed into a heated aroma-generating body, and assembled into an aroma cartridge according to (Manufacturing Example 1). Furthermore, in order to clarify the effect of the inorganic particles, the filling rate was increased. <<Evaluation 1>> was performed on the fragrance cartridge thus produced. Furthermore, the following <<Evaluation 2>> was conducted using the heated electronic cigarette device described in <<Evaluation B>>.

≪Evaluation 2≫
After checking the dirt attached to the heating element 113 when the aroma cartridge was used as shown in FIG. 2(C), the following evaluation was performed. First, using the aroma cartridge of Comparative Example 1, suction was performed 14 times for each cartridge, and the dirt attached to the heating element after 10, 20, 30, 40, and 50 suctions were removed. Wipe with ethanol-impregnated gauze and record the degree of staining. Then, in the same manner as in Comparative Example 1, stains were collected when 50 various aroma cartridges of this example, which were manufactured using heated aroma-generating fillers with various inorganic particles attached to the surface, were sucked. Comparative evaluation was made with the recorded degree of staining. As an evaluation index, the degree of contamination when 50 various aroma cartridges of this example were sucked was determined as the same number as the degree of contamination when suction was made using the aroma cartridge of Comparative Example 1. Therefore, the smaller the number, the better.

(Example I)
From the heated aroma-generating sheet produced in (Production Example 1), 1 part by mass of calcium carbonate powder having an average particle diameter of 15 μm was added to 100 parts by mass of the heated aroma-generating filler cut as described above.

Then, an aroma cartridge was assembled from this heated aroma generator and the mouthpiece. When the filling rate of the filler in this case was measured, it was 81%.

(Example VI)

In this case as well, microscopic observation did not confirm that silicon oxide particles with a diameter of 10 μm to 50 μm were attached to the heated aroma-generating filler, but the heated aroma-generating filler sprinkled with silicon oxide particles was 0.5 μm thick. A heated aroma generator was prepared using 29 g. Then, an aroma cartridge was assembled from this heated aroma generator and the mouthpiece. When the filling rate of the filler in this case was measured, it was 81%.

(Example VII)

An aroma generator was created. Then, an aroma cartridge was assembled from this heated aroma generator and the mouthpiece. When the filling rate of the filler in this case was measured, it was 65%.

(Comparative Example I)
A heated aroma generating body was produced using 0.29 g of the heated aroma generating filler cut as described above from the heated aroma generating sheet produced in (Manufacturing Example 1). Then, an aroma cartridge was assembled from this heated aroma generator and the mouthpiece. When the filling rate of the filler in this case was measured, it was 81%.

The above evaluation results are shown in Table 2. As is clear from the table, inorganic particles with a wide range of particle sizes function as gas generation sustaining materials, regardless of their material. As is clear from the results of <<Evaluation 1>>, there is no occurrence of fusion of the heated aroma-generating filler over time, and there is little change over time in both the amount of gas released, that is, the amount of gas sucked, and the flavor. Although the reason for such an effect is not clear, it is thought to be as follows. When inorganic particles exist on the surface of the filler, they act as spacers and reduce the contact area between the fillers, inhibiting fusion between the fillers due to bleed-out of the aerosol former, even if the fillers are left in a high temperature state for a long time. It is thought that the inorganic particles have the effect of suppressing the bleed-out of the aerosol former.

Furthermore, as is clear from <<Evaluation 2>>, it was recognized that the inorganic particles also have the effect of preventing contamination of the heating element. In particular, when the average particle diameter of the inorganic powder to be added is 1 to 50 μm, a good effect is obtained, and when it is 5 μm or more, the effect of preventing contamination is further enhanced. When the amount of the inorganic powder added is 0.01 to 5 parts by mass, a good effect is obtained, and when it is 0.1 part by mass or more, the effect of preventing contamination is further enhanced. The reason why inorganic particles have the effect of preventing heating elements is not clear, but it is presumed as follows. The inorganic substances are difficult to thermally decompose, the inorganic particles polish the surface and remove contaminants when the aroma cartridge is attached to and detached from the heating element, and the inorganic particles come into contact with the heating element surface and the heated aroma-generating filling. Examples include reducing the area.

In order to obtain such an effect, it is preferable that the inorganic particles have an average particle diameter of 1 to 100 μm. When the average particle diameter is less than 1 μm, the effect of the inorganic particles is reduced. On the other hand, if it is 5 μm or more, the effect of the inorganic particles is enhanced, so it is more preferable. For the same reason, the thickness is even more preferably 10 μm or more. Further, as the particle size increases, the filling rate of the filler decreases, but if the particle size is 50 μm or less, the effect of the inorganic particles is large and it is possible to ensure the minimum necessary filling rate.

Here, the minimum filling rate is closely related to the suction amount of gas generated by heating. When the filling rate is less than 60%, a sufficient amount of gas is not released due to heating, and the amount of gas inhaled by the smoker is insufficient, resulting in an unsatisfactory smoking experience. Therefore, a filling rate of preferably 65% or more, and even more preferably 70% or more is required. On the other hand, if the filling rate exceeds 90%, problems arise in that there are few spaces between the fillings, making it difficult to smoke and difficult to insert into the heating element.

Note that such a filling rate can be evaluated by a method of calculating the area ratio occupied by the heated aroma-generating base material in the cross section of the heated aroma-generating body. It was determined by using a digital microscope to evaluate the filled space and the void area without the filled space. A digital microscope (manufactured by Keyence Corporation: VHX-2000) was used to project the image onto a display at a magnification of 100 times. The range in which the image is analyzed is defined as a region in which only the filler and the void portion without the filler appear. In this case, the diameter of the observation sample was 7.0 mm, and the width was 3.5 mm and the length was 2.6 mm. In the above range, image analysis was performed using the attached software, with the "automatic measurement mode" and the "extraction mode" set to "luminance". For measurement, "Standard" was selected, "Extraction parameter" was set to "Bright", and "Threshold" was selected to separate the observed filling and voids. The filling rate was defined as the ratio of the filling material to the entire measurement area.

Further, the average particle diameter of the inorganic particles in the present invention was determined by a wet method using a laser diffraction/scattering particle size distribution measuring device. In the present invention, Microtrac MT3300III manufactured by Microtrac Bell Co., Ltd. was used. The average particle diameter of the present invention refers to the median diameter D ₅₀ of 50% obtained by accumulating the volume-based distribution in the range from 0.02 μm to 2000 μm.

Furthermore, the presence of inorganic particles in the present invention was confirmed not only by microscopic observation during the manufacturing process [means] but also by observing the surface of the filler using an optical microscope or an electron microscope. Furthermore, it was confirmed by microscopic or electron microscopic observation of the residue after thermally decomposing the filler. This is based on the observation results of about 10 images when one field of view is 100 μm×100 μm at an appropriate magnification. Furthermore, it was confirmed using a scanning electron microscope equipped with X-ray microanalysis (XMA) that the remaining inorganic particles were the added inorganic particles.

The amount of inorganic particles added is at least 0.001 parts by mass per 100 parts by mass of the filler in order to exhibit the effect, and it is more preferably 0.01 parts by mass or more, and 0.05 parts by mass or more. It is even more preferable that the amount is at least parts by mass. On the other hand, if the amount exceeds 10 parts by mass per 100 parts by mass of the filler, the filling rate of the filler will decrease, which will affect the amount of gas sucked and the flavor. From such a viewpoint, it is more preferably 5 parts by mass or less, and even more preferably 2 parts by mass or less.

Inorganic substances that can be used as the inorganic particles of the present invention are not particularly limited, but include metal chlorides such as sodium chloride and potassium chloride, metal oxides such as magnesium oxide, calcium oxide, titanium oxide, iron oxide, and alumina. metal carbonates such as magnesium carbonate and calcium carbonate, metal sulfates such as magnesium sulfate and calcium sulfate, metal phosphates such as calcium phosphate, and titanates such as potassium titanate and magnesium titanate alone. Alternatively, two or more can be selected and used. Furthermore, silicon oxides such as zeolite, colloidal silica and fumed silica, and natural products such as diatomaceous earth and vermiculite can also be used. Particularly preferred are magnesium carbonate, calcium carbonate, silicon oxide, and alumina.

In this way, the inorganic particles can be attached to the heated aroma-generating substrate in the dispersion step [means] H2 in FIG. 32, but they can also be made to adhere in the dispersion step [means] S4 in FIG. Furthermore, as shown in FIGS. 28 to 31, inorganic particles can be added to the heated aroma-generating composition to produce a heated aroma-generating base material containing inorganic particles. In the case of this method [apparatus], although the inorganic particles are not present only on the surface of the heated aroma-generating substrate, it has been confirmed that the effects of the inorganic particles are expressed. For this reason, inorganic particles function as gas generation sustaining materials because they not only act as spacers that inhibit fusion between the heated aroma-generating substrates, but also reduce the contact area between the heated aroma-generating substrates. It is presumed that the movement of constituent materials such as the aerosol former, non-tobacco material, and binder inside is impeded. This assumption is based on the assumption that when inorganic particles are used as fillers in polymeric materials, they play the role of crosslinking points and improve chemical properties such as heat resistance and chemical resistance, and physical properties such as tensile strength and elastic modulus. Based on improving.

As described above, according to the present invention, by improving the manufacturing method [device], a heated aroma generator in which the heated aroma generating base material functions as a gas generation sustaining material, and a heated aroma generator in which inorganic particles function as a gas generation sustaining material A generator can be provided. Therefore, as shown in FIG. 33, it is also possible to provide an aroma cartridge that does not require a gas suction optimization means in the mouthpiece. Of course, it is also possible to provide an aroma cartridge combining a heated aroma generator with gas production sustaining material and a mouthpiece with gas suction optimization means.

The present invention is a harmless aroma derived from plants that does not contain tobacco, a member of the genus Tobacco of the Solanaceae family, or its congenerous plants, or any of its components. We can provide an aromatic cartridge that allows you to enjoy smoking as if you were smoking a cigarette, so that not only the smoker himself but also the non-smokers around him can enjoy smoking without adversely affecting his health. It is a new smoking device that brings alpha waves into the brain, has a healing effect, and is useful for improving health and beauty. Furthermore, since the fragrance cartridge is equipped with a gas suction optimization means and a gas production sustaining material, it has the characteristic that the suction amount and flavor of smoke and aroma components do not change even if stored for a long period of time. Therefore, the technology related to the fragrance cartridge of the present invention may be widely applicable to incense sticks, burnt incense, powdered incense, incense anointing, aromatherapy, and the like.
