Description

Technical Field

[0001] The present invention relates to a composition constituting a stick-shaped heated aromatic generating base material containing an aerosol former that generates an aerosol by heat transmitted by an electric heat source instead of a flame, a stick-shaped heated aromatic generating base material using the composition, and an aromatic cartridge using the stick-shaped heated aromatic generating base material.

[0002] In particular, it provides a composition constituting a stick-shaped heated aromatic generating base material that does not contain any components of tobacco and its congeners belonging to the Solanaceae tobacco genus, and has a strong "flavor", which is a fragrance felt throughout the oral cavity when the heated aromatic generating base material is heated and inhaled together with an aerosol, a stick-shaped heated aromatic generating base material using the composition, and an aromatic cartridge using the stick-shaped heated aromatic generating base material.

[0003] More specifically, the present invention relates to a stick-shaped heated aromatic generating base material composition mainly composed of various materials such as specific parts of angiosperms containing many aroma components that are effective in promoting physical and mental relaxation, health, and beauty by smoking, a stick-shaped heated aromatic generating base material using the composition, and an aromatic cartridge using the stick-shaped heated aromatic generating base material.

Background Art

[0004] In recent years, with the widespread adoption of designated smoking areas and smoking bans in workplaces, restaurants, and other places where people gather, the number of smokers who inhale the smoke produced by burning tobacco, such as with conventional cigarettes, has decreased. Conversely, the number of smokers who use e-cigarettes, which are heated smoking devices that allow users to inhale smoke or vapor generated by heat transmitted by a heat source such as a heater, has increased dramatically. This is because, with conventional flame-based smoking, smokers and non-smokers around them inhale harmful substances produced by the thermal decomposition and combustion of tobacco leaves and paper. In contrast, with e-cigarettes, smokers can inhale harmless smoke or vapor made from non-tobacco materials, without the thermal decomposition and combustion of tobacco leaves, allowing them to enjoy smoking while also reducing the impact on non-smokers around them.

[0005] There are roughly two types of these e-cigarettes (Non-Patent Documents 1 and 2). One type is the capsule-type and stick-type e-cigarettes, which heat capsules or sticks containing tobacco leaves or the like to produce vapor for inhalation. The other type is the liquid-type e-cigarette, which heats a flavored or aromatic liquid to produce vapor for inhalation.

[0006] In particular, stick-type e-cigarettes have a high degree of similarity to conventional cigarettes in terms of form, smoking method, and taste, and because they contain less harmful substances than cigarettes, they have many enthusiasts and various developments are underway (for example, Patent Documents 1-3). Specifically, an e-cigarette is smoked by attaching a stick equipped with a mouthpiece to an aerosol forming body, which is an aerosol forming base material processed into a stick shape similar to a cigarette with an aerosol former that generates an aerosol that becomes smoke along with tobacco components, flavorings, binders, etc. The smoking mechanism is such that when the aerosol forming base material is attached to the heat source of the heated smoking device and heated, volatile substances including the aerosol former are released from the aerosol forming base material. At the same time, these volatile substances are drawn in with air to the mouthpiece side at the other end by the smoker's inhalation. In this volatile substance transport process, the volatile substances of the aerosol former are cooled and condensed to form an aerosol that resembles smoke, while other volatile substances provide an aroma to the smoker's mouth and nose, resulting in the enjoyment of smoking (Patent Document 2). According to this mechanism, heated smoking methods, such as stick-type e-cigarettes, allow smoking at temperatures of around 200-350°C, which is the temperature at which the aerosol former, such as glycerin or propylene glycol, contained in the aerosol-forming substrate, can be volatilized, or at the temperature at which the thermal decomposition of tobacco leaves begins. Therefore, compared to flame-type smoking, which burns at temperatures of at least 600°C necessary for combustion and even exceeding 900°C during smoking, heated smoking suppresses the generation of harmful substances, which are said to increase in amount with rising temperatures, and thus has fewer adverse effects on health.

[0007] Furthermore, unlike stick-type e-cigarettes, liquid-type e-cigarettes do not contain tobacco components and are a new smoking device that allows users to enjoy a variety of flavors, such as beverages like coffee, cola, and Red Bull; desserts like chocolate, vanilla, and cream; fruits like orange, lemon, and melon; and cooling agents like menthol, mint, and herbs (Non-Patent Literature 2). Specifically, it is an e-cigarette in which a liquid mixture of propylene glycol and vegetable glycerin with flavorings is heated and the vaporized substance is inhaled. Its greatest feature is that it contains absolutely no harmful substances, does not produce tar or nicotine, and allows users to enjoy a wide variety of flavors, and in fact, a wide variety of liquids are sold.

[0008] Based on these two types of e-cigarettes, an e-cigarette that combines the features of both has been developed (Patent Document 4). As mentioned above, the aerosol-forming substrate processed into a heated stick shape in conventional stick-type e-cigarettes contained tobacco components, resulting in the generation of harmful substances, including tar and nicotine, albeit in small amounts. Therefore, Patent Document 4 discloses a stick-type e-cigarette that does not contain tobacco components, which was a problem with stick-type e-cigarettes. In other words, this stick-type e-cigarette uses non-tobacco plants that generate only aromas that have beneficial effects on mental and physical relaxation, health, and beauty through smoking, instead of tobacco components, and is a stick-type e-cigarette that is formulated with an aerosol former, fragrance, binder, etc.

[0009] However, unlike liquid-type e-cigarettes, stick-type e-cigarettes using non-tobacco plants require the aerosol-forming substrate to be processed into a stick shape, with the ingredients firmly attached without falling off. However, materials containing a large amount of aromatic components that produce a strong "flavor"—the scent felt throughout the mouth when the aerosol formed by evaporation with the aerosol former is inhaled—generally have little fiber, making it difficult to firmly attach these materials. As a result, stick-type e-cigarettes have had difficulty producing the strong taste and refreshing sensation throughout the mouth that liquid-type e-cigarettes do. Consequently, stick-type e-cigarettes have had to limit the types of flavors they can offer.

[0010] The challenges inherent to this stick-shaped aerosol-forming substrate are also observed in conventional stick-type e-cigarettes containing tobacco components. For example, Patent Document 1 describes a tobacco sheet for an aerosol-forming substrate that includes at least an aerosol former, a flavoring, a binder, and tobacco material. In this tobacco sheet, tobacco leaf fragments, tobacco stems, tobacco dust, and / or main leaf blade fragments of tobacco leaves generated during tobacco processing are used as tobacco material and are present in an amount of at least 50% by weight. Patent Document 2 also describes an aerosol-forming substrate composed of an elongated strand containing at least an aerosol former, a flavoring, a binder, and tobacco material. In this strand, tobacco material is present in an amount of at least 75% by weight.

[0011] Thus, because stick-type e-cigarettes must be processed into a stick-shaped aerosol-forming substrate, it is not possible to incorporate large amounts of materials or fragrances that contain many aromatic components that create the "flavor" perceived throughout the mouth when the aerosol generated by volatilization together with the aerosol former is inhaled. This presents an inherent challenge in that users inhale a "flavor" that is a complex mixture of aromatic components generated by heating tobacco leaves or non-tobacco plants, and aromatic components from materials or fragrances that contain many aromatic components that create the "flavor."

[Overview of the Initiative] [Problems that the invention aims to solve]

[0014] Unlike liquid-type e-cigarettes, stick-type e-cigarettes require the formulation to be firmly attached to a stick-shaped aerosol-forming substrate without falling off. However, materials containing a large amount of aromatic components that strongly contribute to the "flavor"—the scent perceived throughout the mouth when the aerosol formed by evaporation with the aerosol former is inhaled—generally have low fiber content, making them difficult to adhere. Therefore, it was necessary to add tobacco leaves or non-tobacco plants to help them adhere. As a result, stick-type e-cigarettes have the problem of inhaling a "flavor" that is a complex mixture of aromatic components generated when tobacco leaves or non-tobacco plants are heated, and aromatic components from materials or fragrances that contain a large amount of aromatic components that contribute to the "flavor." This makes it difficult to provide the strong taste and refreshing sensation throughout the mouth that liquid-type e-cigarettes offer. Consequently, stick-type e-cigarettes had to limit the types of flavors they could offer.

[0015] The present invention aims to solve these problems and provide a composition for forming a stick-type heated aroma-generating substrate that does not contain any tobacco or related plants of the Solanaceae family, nor any of their components, and that has a strong "flavor"; a stick-type heated aroma-generating substrate using the composition; and an aroma cartridge using the stick-type heated aroma-generating substrate.

[0016] More specifically, the present invention provides a composition for forming a stick-type heat-sensitive aroma-generating substrate containing an aerosol former that generates an aerosol by heat transferred by a heat source, characterized in that the composition comprises an aerosol former, a material containing an aroma component that emits a flavor that lingers in the mouth when the stick-type heat-sensitive aroma-generating substrate is heated and inhaled together with the aerosol, and an adsorbent that holds liquid components containing the aroma component possessed by the material containing the aroma component. Furthermore, the present invention provides a stick-type heat-sensitive aroma-generating substrate using the composition, and an aroma cartridge using the stick-type heat-sensitive aroma-generating substrate.

[0017] Conventionally, a substrate that, when inserted into a heating element and heated, volatilizes an aerosol former that generates an aerosol, as well as the fragrance components of a fragrance base material or fragrance agent, has generally been called an "aerosol-forming substrate." However, since the smoke from the aerosol and the fragrance of the fragrance base material or fragrance agent are enjoyed through smoking, in this invention, it will be called a "heated fragrance-generating substrate." Based on this, an assembly of aerosol-forming substrates will be called a "heated fragrance-generating source," what has been called an "electronic cigarette," "electronic cigarette cartridge," or "cartridge" equipped with an aerosol-generating source will be called a "fragrance cartridge," and a "smoking device" equipped with a heating element for smoking with a "fragrance cartridge" attached will be called a "fragrance device."

[0018] In particular, the fragrance cartridge of the present invention does not contain tobacco components and is a stick-shaped object wrapped in packaging material, comprising a heated fragrance generating base material composed of at least an aerosol former such as glycols or glycerin and a material containing fragrance components, with at least a mouthpiece. This fragrance cartridge is attached to a heated fragrance device equipped with a heat source, and is used to enjoy the smoke and fragrance of the aerosol formed by the cooling and condensation of volatile substances of the aerosol former generated by heating, and the fragrance components released by heating, by inhaling them through the mouthpiece, while the handling is similar to that of a cigarette, the smoke and fragrance are completely different. Therefore, the fragrance cartridge of the present invention allows users to enjoy fragrances that are not based on tobacco components, but rather on beverages such as coffee, cola, and red bull, desserts such as chocolate, vanilla, and cream, fruits such as orange, lemon, and melon, and cooling agents such as menthol, mint, and herbs. [Means for solving the problem]

[0019] As a result of investigating the aroma components contained in various materials such as various parts of a wide variety of angiosperms, the present inventors found a material containing a large amount of aroma components that are effective in promoting mental and physical relaxation, health, and beauty through smoking. At the same time, the inventors found an adsorbent for retaining a composition containing the aroma components that make up this material, and thus completed the present invention. Furthermore, the inventors found that it is preferable to blend a fixable holding material that can be processed into a stick-shaped heated aroma-generating base material in a heated aroma-generating base material composition containing, as a main component, a material containing a large amount of the aroma components, thereby enhancing the completion level of the present invention.

[0020] That is, the present invention is a composition for forming a stick-type heated aroma-generating base material containing an aerosol former that generates an aerosol by heat transmitted by a heat source, the composition comprising: an aerosol former; a material containing a large amount of aroma components that emit a flavor, which is a scent that lingers in the mouth when the stick-type heated aroma-generating base material is heated and inhaled together with the aerosol; and an adsorbent for retaining a liquid component containing the aroma components possessed by the material containing the aroma components. More preferably, the present invention is a stick-type heated aroma-generating base material composition further comprising a holding material that can be processed into a stick-shaped heated aroma-generating base material.

[0021] The adsorbent material can preferably be cross-linked polyvinylpyrrolidone (PVP) or silica powder. Other materials that can preferably be used include chitosan, chitosan derivatives, activated carbon, aluminum oxide, activated clay, and zeolite. Cross-linked PVP can be commercially available products such as BASF Europe's DiverGun® or ISP's Polyclar® VT. On the other hand, silica powder can be used in a wide range of applications, from spherical silica particles with a primary particle diameter on the order of tens of nanometers, such as fumed silica which is mainly used to improve the rheological properties of inks and paints, to spherical silica particles with a primary particle diameter of several micrometers which are used as antiblocking agents or matting agents for inks and paints, or as reinforcing agents for paints and rubber. However, for the adsorbent material of the present invention, it is preferable that the primary particle diameter is on the order of submicrons, i.e., spherical silica particles with an average primary particle diameter of 0.1 to 1.0 μm. Examples of such silica powders include P10 (average primary particle diameter: 0.1 μm), P30 (average primary particle diameter: 0.3 μm), P50 (average primary particle diameter: 0.5 μm), and P100 (average primary particle diameter: 1.0 μm) of the high-purity silica spherical fine particle powder SeaHostar (registered trademark) KE-S manufactured by Nippon Shokubai Co., Ltd., as well as functional spherical silica HPS-0500 (average primary particle diameter: 0.5 μm) and HPS-1000 (average primary particle diameter: 1.0 μm) manufactured by Toagosei Co., Ltd., and submicron spherical silicon micropowder HM051-11 (average primary particle diameter: 0.5 μm) manufactured by Powder Technology Co., Ltd. The surface of such silica powder is a hydrophilic surface with a high concentration of silanol groups, but silica powder hydrophobized with alkylchlorosilane or alkoxysilane can also be used. In particular, when the material containing the fragrance components contains a large amount of lipophilic components, hydrophobic silica powder is preferred. Furthermore, while silica powder used in general industrial products such as inks and paints is not porous silica powder, when used as a catalyst carrier or adsorbent, porous silica powder with a very large specific surface area having pores of several nanometers to tens of nanometers is used. Therefore, it is preferable to use porous silica powder as the silica powder of the present invention.Chitosan, chitosan derivatives, activated carbon, aluminum oxide, activated clay, zeolite, etc. are preferably used in powder form. Zeolite can be either natural zeolite or synthetic zeolite, and zeolite processed into spherical, pellet-like, or hollow fiber-like shapes can also be preferably used.

[0022] Such adsorbents retain the liquid components containing the fragrance components of the materials containing the fragrance components, that is, the lipophilic components containing the fragrance components and the hydrophilic components containing the fragrance components, in the heated fragrance-generating base material produced from the composition of the present invention, temporarily adsorb and fix the fragrance components having hydrophilic groups such as hydroxyl groups, ether bonds, ester bonds, etc., and play a role in retaining the lipophilic and hydrophilic components in which the fragrance components are dissolved. When heated during smoking, it is considered that the fragrance components quickly volatilize together with the aerosol former.

[0023] Although the mechanism by which such functions are achieved is not clear, in the case of crosslinked PVP, it is presumed to function as a protective colloid that can emulsify lipophilic and hydrophilic components because it has a lipophilic part of the network formed by hydrocarbons constituting the main skeleton and a hydrophilic part of the pyrrolidone bonded to the side chain. On the other hand, in the case of silica powder, it is considered that the silanol groups distributed on its surface at a high concentration adsorb the hydrophilic components, resulting in a continuous layer of lipophilic components and a discontinuous layer of hydrophilic components, similar to the state emulsified by a protective colloid. Also, it is considered that the adsorptive ability due to the huge specific surface area with a large amount of fine pores of the porous silica powder is deeply involved. From such a perspective, chitosan and its derivatives are polyelectrolytes having amino groups and are considered to have the same mechanism as crosslinked PVP. And aluminum oxide has a similar effect to silica due to the large amount of hydroxyl groups present on its surface, and activated clay and zeolite are considered to have a similar effect to porous silica powder due to the adsorptive ability based on the huge specific surface area with fine pores.

[0024] Cross-linked PVP, silica powder, chitosan, chitosan derivatives, activated carbon, aluminum oxide, activated clay, and zeolites have important functions as adsorbents, and also have the advantage of not generating aroma components when heated, and not negatively affecting the flavor perceived in the mouth by aroma components emitted from materials containing aroma components.

[0025] Furthermore, the material containing fragrance components must be present in an amount of 5 to 50% by mass of the total mass of the stick-type heat-activated fragrance generating substrate composition. If it is less than 5% by mass, the flavor perceived in the oral cavity when the stick-type heat-activated fragrance generating substrate produced from the stick-type heat-activated fragrance generating substrate composition is heated and inhaled will be insufficient. If it exceeds 50% by mass, there will be fewer fibers in the material containing fragrance components and more liquid components containing fragrance components, which will cause problems such as the material containing fragrance components falling off or breaking during the molding process from the stick-type heat-activated fragrance generating substrate composition to the stick-type heat-activated fragrance generating substrate. In addition, there is also the problem of obstruction of the passage of volatile substances when the stick-type heat-activated fragrance generating substrate is heated and inhaled.

[0026] In order to retain the liquid components containing the fragrance components contained in the material blended in this way, it is preferable that the blending ratio of the material containing the fragrance components to the adsorbent be approximately 1:1 to 43:1 (by mass). If the amount of adsorbent is less than 43:1, the liquid components containing the fragrance components cannot be sufficiently retained, resulting in the problem of the liquid components separating. In the process of molding the stick-type heated fragrance generating substrate composition into a stick-type heated fragrance generating substrate, the material containing the fragrance components may fall off or break. Furthermore, when heating and suctioning the stick-type heated fragrance generating substrate, the passage of volatile substances may be obstructed. Conversely, if the amount of adsorbent is more than 1:1, the adsorbent strongly retains moisture through hydrogen bonding, resulting in the problem of a longer drying time.

[0027] Furthermore, when blending the aerosol former, which generates smoke as an aerosol, with the material containing the fragrance component and the adsorbent, it is preferable that the total amount of the aerosol former and the material containing the fragrance component and the adsorbent be in a blending ratio of approximately 1.9:1 to 1:1 (by mass). With this blending ratio, when the stick-type heated fragrance generating base material is heated and inhaled, it is possible to generate a moderate amount of smoke similar to that of a cigarette.

[0028] Furthermore, it is preferable that the main composition of the stick-type heated fragrance generating base material contains 5 to 25% by mass of water, based on the total mass. The water can be tap water, boiling water, distilled water, ion-exchanged water, etc., but is preferably general pure water, not limited to the manufacturing method. If the amount is less than 5% by mass, problems occur such as the detachment or breakage of the material containing the fragrance components during the molding process from the stick-type heated fragrance generating base material composition to the stick-type heated fragrance generating base material. If the amount exceeds 25% by mass, the viscosity of the stick-type heated fragrance generating base material composition becomes too low, making it difficult to mold into the stick-type heated fragrance generating base material, and also resulting in a longer drying time.

[0029] Thus, the composition for forming the stick-type heated aroma-generating substrate of the present invention comprises at least an aerosol former, a material containing an aroma component that emits a fragrance (flavor) that lingers in the mouth when inhaled together with the aerosol, and an adsorbent that holds the liquid component containing the aroma component present in the material containing the aroma component. However, it is more preferable to add a fourth component, which is a retaining material that fixes the aerosol former, the material containing the aroma component, and the adsorbent. This retaining material not only allows for the more stable production of the stick-type heated aroma-generating substrate, but also allows the aerosol former that volatilizes together with the aroma component when the stick-type heated aroma-generating substrate is heated to pass through the substrate without resistance, enabling a smoking experience where one can enjoy a flavor that soothes the mind and body.

[0030] In other words, the present invention is a composition for forming a stick-type heated aroma-generating substrate containing an aerosol former that generates an aerosol by heat transferred by a heat source, and more preferably comprises an aerosol former, a material containing an aroma component that emits a fragrance (flavor) that lingers in the mouth when the stick-type heated aroma-generating substrate is heated and inhaled together with the aerosol, an adsorbent that holds the liquid component containing the aroma component of the material containing the aroma component, and a retaining material that fixes the aerosol former, the material containing the aroma component, and the adsorbent.

[0031] The retaining material is preferably a non-tobacco material containing 30% or more by dry mass of fiber (cellulose). Non-tobacco materials containing a large amount of fiber have a high ability to fix aerosol formers, materials containing fragrance components, and adsorbents, and can solve the problem of the material containing fragrance components falling off or breaking during the molding process from the stick-type heated fragrance generating base material composition to the stick-type heated fragrance generating base material. Moreover, because there are few components other than fiber, when the stick-type heated fragrance generating base material is heated, fewer unwanted fragrance components volatilize, and it has the advantage that only the fragrance of the material containing fragrance components can be enjoyed as a flavor in the mouth. The fiber itself is so-called cellulose, and since it is mixed with aerosol formers that volatilize at 200-250°C with a decomposition temperature of approximately 350°C, there are almost no volatile components.

[0032] Furthermore, it is more preferable to use non-tobacco plants with fiber diameters of 10-50 μm. This is because the smaller the fiber diameter, the greater the ability to fix aerosol formers, materials containing aroma components, and adsorbents. However, this lower limit of fiber diameter is based on the diameter of the thinnest plant fibers and is not intentionally set.

[0033] Non-tobacco plants containing 30% or more fiber by dry weight include the stems and leaves of plants in the Linaceae family (Marpales), Urticaceae family (Urticales), Malvales family (Malvaceae), Cannabaceae family (Rosales), Musaceae family (Zingiberales), Asparagaceae family (Asparagaceae), Poaceae family (Grasses), Cyperaceae family (Cyperaceae), Juncaceae family (Rump), Eriocaulaceae family (Eriocaulaceae), Typhaceae family (Typha), Bromeliaceae family (Bromeliad), mushrooms (caps, gills, stalks, rings, volva), cotton, the bark of plants in the Thymelaeaceae family (Myrtales), and the bark of plants in the Moraceae family (Rosales). Each of these can be used individually or in combination.

[0034] Specific examples of plants belonging to the Malpighiales order, Linaceae family; Urticaryales order, Urticaceae family; Malvales order, Malvaceae family; Rosales order, Cannabaceae family; Zingiberales order, Musaceae family; and Asparagales order, Asparagaceae family include linen, ramie, jute, kenaf, hemp, Manila hemp, and sisal hemp. Specific examples of plants belonging to the Grasses order, Poaceae family include rice, barley, wheat, wild oats, adlay, rye, sorghum, maize, millet, sugarcane, foxtail millet, goosegrass, pearl millet, barnyard grass, foxtail millet, foxtail millet, wild rice, dwarf bamboo, Japanese pampas grass, esparto, briar grass, bamboo grass, and bamboo. Specific examples of plants belonging to the Cyperaceae, Juncaceae, Eriocaulaceae, Typhaceae, and Bromeliaceae families of the order Poales include papyrus, sedge, bulrush, rush, star grass, cattail, and pineapple.

[0035] Specific examples of edible mushrooms include matsutake, giant oyster mushroom, oak mushroom, buna shimeji, hatake shimeji, hon shimeji, mukitake, oyster mushroom, shiitake, golden mushroom, kabayoro tsurutake, moehitake, kuritake, nameko, slime mushroom, white nametsumutake, agaric, white agaric, button mushroom, mujinatake, mureofure urinari, kawamura urinari, and purple aburashimejimodo. Examples of mushrooms include *Boletus edulis*, *Boletus reticulatus*, *Boletus edulis*, *Boletus purpurea*, *Suillus luteus*, *Lactarius deliciosus*, *Lactarius luteus*, *Lactarius luteus*, *Suillus luteus*, *Ganoderma lucidum*, *Hericium erythrorhizon*, *Hericium uliginosum*, *Hericium purpureus*, *Minaria mellea*, *Auricularia polytrichum*, *Thuidium delicatulum*, *Rhizophora spp.*, *Phallus impudicus*, *Lycoperdon perforatum*, and *Phellaria nipponicus*. Cotton refers to the fiber obtained from the seeds of the cotton plant, a perennial herb belonging to the genus *Gossypium* in the family Malvaceae, order Malvales. Specific examples of plants belonging to the family Thymelaeaceae in the order Myrtales and the family Moraceae in the order Rosales include *Edgeworthia chrysantha*, *Platycerium sempervirens*, and *Patrinia scabiosifolia*.

[0036] Among the specific examples above, the stems, leaves, and bark of non-tobacco plants other than mushrooms, which contain 50% or more fiber by dry mass, and cotton are more preferred. However, wood ear mushrooms contain 50% or more fiber and are preferably used. Furthermore, the stems, leaves, and bark of non-tobacco plants other than ramie, which have a fiber diameter of 10 to 50 μm, and cotton are even more preferred. In particular, the stems and leaves of linen, jute, kenaf, hemp, Manila hemp, and sisal hemp, rice, barley, wheat, oats, adlay, rye, sorghum, corn, millet, sugarcane, foxtail millet, goosegrass, pearl millet, barnyard millet, foxtail millet, fawn, wild rice, dwarf bamboo, Japanese pampas grass, esparto, briar grass, bamboo grass, bamboo, papyrus, sedge, bulrush, rush, star grass, cattail, and pineapple are preferred.

[0037] Even when using such a retaining material, for the same reasons as when not using a retaining material, the material containing the fragrance components must be present in an amount of 5 to 50% by mass of the total mass of the main composition of the stick-type heated fragrance generating base material. Furthermore, the mixing ratio of the material containing the fragrance components, the adsorbent, and the retaining material is preferably approximately 1:1:2 to 43:1:5 (by mass). After various studies, it was found that within this range of mixing ratios, all sorts of problems can be solved, such as the adsorbent not being able to sufficiently retain the liquid component containing the fragrance components (the liquid component containing the fragrance components separating), the material containing the fragrance components falling off or breaking during the molding process from the stick-type heated fragrance generating base material composition to the stick-type heated fragrance generating base material, and the obstruction of volatile matter passage when the stick-type heated fragrance generating base material is heated and inhaled. Moreover, it was confirmed that the fragrance components generated by heating the material containing the fragrance components do not adversely affect the flavor perceived in the mouth.

[0038] When using a retaining material, the amount of aerosol former that can be heated and inhaled as a stick-type heated fragrance generating base material to generate a moderate amount of smoke similar to that of a cigarette is preferably in a ratio of 2:1 to 0.3:1 (by mass) of the total amount of aerosol former, fragrance component-containing material, adsorbent, and retaining material.

[0039] Furthermore, the amount of water required to process the stick-type heated fragrance-generating substrate composition into a stick-type heated fragrance body is 5 to 25% by mass of the total mass of the main composition of the stick-type heated fragrance-generating substrate, just as when no retaining material is used. This avoids problems such as the detachment or breakage of materials containing fragrance components, the problem of the viscosity of the stick-type heated fragrance-generating substrate composition becoming too low, making it difficult to mold into a stick-type heated fragrance-generating substrate, and the problem of excessively long drying times.

[0040] Thus, in order to manufacture a stick-type heated fragrance generating base material using a material containing a large amount of fragrance components, it is essential to add an adsorbent to the composition used for its manufacture, and it is even more preferable to add a retaining material. This is because, as can be seen from the specific materials containing a large amount of fragrance components described below, materials containing a large amount of fragrance components contain a large amount of liquid components containing fragrance components, and do not contain much fiber.

[0041] As described later, the manufacturing of a stick-type heated fragrance generating substrate involves processes such as crushing a material containing a large amount of fragrance components, dispersing the crushed material in water, and forming a sheet from the dispersion. In each of these processes, liquid components containing fragrance components precipitate from the material containing a large amount of fragrance components. Without an adsorbent for these liquid components, the fragrance components and / or liquid components separate, causing molding problems such as the material containing fragrance components falling off or breaking, making it impossible to form a sheet. Furthermore, even when the stick-type heated fragrance generating substrate is heated and suctioned, it may be difficult for the fragrance components and volatile components of the aerosol former to pass through. These issues are the same whether the liquid components containing fragrance components are lipophilic or hydrophilic, but are more pronounced in the case of lipophilic components.

[0042] Adding a retaining agent fixes the aerosol former, the material containing fragrance components, and the adsorbent, thus solving molding problems such as the material containing fragrance components falling off or breaking, preventing the formation of a sheet. Furthermore, the fibers create appropriate spaces, allowing volatile components to pass through easily through suction. Moreover, even when the fibers are heated, the fragrance components released from the material containing fragrance components have little adverse effect on the flavor perceived in the mouth.

[0043] Thus, materials containing large amounts of aromatic components that are difficult to process into stick-type heat-activated aroma-generating base materials include the seeds of angiosperms' fruits, the pulp of angiosperms' fruits, the pericarp of angiosperms' fruits, the fruits of angiosperms, and the stems and leaves of herbs. These can be used individually, or multiple materials can be selected to adjust the flavor perceived in the mouth.

[0044] Specifically, examples of seeds from the fruits of angiosperms include macadamia nuts, hazelnuts, chestnuts, walnuts, almonds, pecans, cashews, pistachios, Brazil nuts, coffee beans, cocoa beans, vanilla beans, nutmeg, cola nuts, peanuts, dill, cumin, juniper, caraway, celery, cardamom, fennel, fenugreek, parsley, ajwain, and anise seeds.

[0045] Even among the seeds of angiosperms, it is preferable to roast macadamia nuts, hazelnuts, chestnuts, walnuts, almonds, pecans, cashews, pistachios, Brazil nuts, coffee beans, cocoa beans, nutmeg, kola nuts, and peanuts, as their aroma intensifies when roasted. This is because roasting increases the aromatic compounds due to the thermal decomposition of the seed's components. For example, in the case of coffee beans, it has been analyzed that the aromatic compounds increase due to the decomposition of chlorogenic acid into caffeic acid and quinic acid, and the decomposition of oligosaccharides into acetic acid and lactic acid (Non-Patent Literature 3).

[0046] On the other hand, some seeds of angiosperms also increase in aromatic compounds through fermentation, and fermented vanilla beans are particularly preferable.

[0047] Even when seeds containing a large amount of lipophilic components such as oils and fats and low fiber content are used as a material containing a large amount of aroma components, the emulsifying action of the cross-linked PVP adsorbent, the water absorption function of the silica powder, and the adhesive function of the retaining material work extremely effectively, allowing the liquid components containing aroma components to be sufficiently retained. As a result, the liquid components containing aroma components are separated, solving problems such as the detachment of the material containing aroma components and the breakage of the stick-type heated aroma-generating substrate during molding from the stick-type heated aroma-generating substrate composition to the stick-type heated aroma-generating substrate, as well as the problem of obstruction of the passage of volatile substances when the stick-type heated aroma-generating substrate is heated and sucked.

[0048] The pulp of angiosperm fruits also contains a large amount of aromatic compounds. Specifically, examples include the pulp of European pear, Chinese pear, peach, fruits of plants in the Rutaceae family, genus Citrus, apples, bananas, pineapples, mangoes, passion fruit, kiwifruit, guavas, durians, mangosteens, papayas, starfruits, lychees, watermelons, pepinos, apricots, cherries, quince, melons, cantaloupes, strawberries, raspberries, blueberries, blackcurrants, grapes of the Vitis vinifesca species in the Vitaceae family, genus Vitis, and grapes of the Vitis labrusca species in the Vitaceae family, genus Vitis. In particular, Valencia oranges, Satsuma mandarins, grapefruits, lemons, limes, and Iyokan oranges are preferred as fruits of plants in the Rutaceae family, genus Citrus.

[0049] Furthermore, the peel of the fruit contains a larger amount of aromatic compounds than the pulp. In particular, the peel of the fruit of plants belonging to the genus Citrus in the family Rutaceae, such as Valencia oranges, Satsuma mandarins, grapefruits, lemons, limes, and Iyokan, is preferred.

[0050] As for the fruits of angiosperms, coriander, allspice, star anise, and pepper are preferably used.

[0051] Furthermore, among the herb stems and leaves, tarragon, basil, rosemary, and lavender stems and leaves are particularly preferred, as are allspice, oregano, thyme, dill, parsley, peppermint plants of the Lamiaceae family, spearmint plants of the Lamiaceae family, lemon balm, hyssop, savory, marjoram, lemongrass, bay leaf, sage, and lemon verbena leaves.

[0052] Furthermore, as materials containing aromatic components, macadamia nuts, hazelnuts, chestnuts, walnuts, almonds, pecans, cashews, pistachios, Brazil nuts, coffee beans, cocoa beans, nutmeg, and the leaves of plants that bear the seeds of kola nuts can also be used. In particular, coffee leaves contain trigonelline, which activates brain nerves, and mangiferin, which has antioxidant properties, and can be preferably used as a material containing healthy aromatic components (Non-Patent Literature 4).

[0053] Even when using the pulp, peel, and entire fruit of such angiosperms as materials containing large amounts of aromatic compounds, adsorbents and retainers are useful because many of these aromatic compounds are lipophilic and they contain few fibers. In particular, in the case of fruit pulp, which contains a lot of water, there is a high need for adsorbents such as cross-linked PVP or silica powder that have the function of retaining water, as well as for retainers with adhesive properties.

[0054] On the other hand, the aerosol former for forming smoke, which is essential for the stick-type heated aroma-generating substrate of the present invention, contains a large amount of aroma components and, even with materials that have few fibers, can be used individually or in combination with other commonly used materials such as propylene glycol, 1,3-butanediol, sorbitol, ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, glycerin, lactic acid, monoacetin (glycerin monoacetate), diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanedinioate, and dimethyl tetradecanesanedioate. In particular, it is preferable to select and use from propylene glycol, ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, glycerin, monoacetin (glycerin monoacetate), and diacetin (glycerin diacetate).

[0055] It is preferable to further add a thickening agent to the stick-type heated fragrance generating substrate composition of the present invention. This thickening agent adjusts the viscosity of the composition for molding the stick-type heated fragrance generating substrate composition into a stick-type heated fragrance generating substrate, and also assists in the retention of the material.

[0056] In particular, the thickening agent is preferably at least one selected from polysaccharide polymers such as konjac mannan (glucomannan), guar gum, pectin, carrageenan, tamarind seed gum, acacia gum, soybean polysaccharides, locust bean gum, karaya gum, xanthan gum, and agar, and cellulosic polymers such as methylcellulose, ethylcellulose, carboxymethylcellulose, carboxyethylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, and sodium, potassium, and calcium salts of carboxymethylcellulose and carboxyethylcellulose. More preferably, it is at least one selected from carboxymethylcellulose, carboxyethylcellulose and carboxymethylcellulose, and sodium, potassium, and calcium salts of carboxymethylcellulose and carboxyethylcellulose. Such a thickening agent is a type of polysaccharide, similar to fiber, and will not adversely affect the flavor perceived in the mouth due to aroma components generated from materials containing aroma components upon heating.

[0057] The amount of thickener used needs to be adjusted as appropriate depending on the material containing a large amount of fragrance components, but it is sufficient to add 1.0 to 5.0% by mass of the thickener relative to the total mass of the main composition of the stick-type heated fragrance generating base material.

[0058] It is preferable to add β-cyclodextrin, a cyclic compound of dextrin containing hydroxyl groups, as an adsorption aid, in addition to assisting the adsorbent and particularly for retaining aroma components containing hydroxyl groups. β-cyclodextrin is known to form inclusion compounds with menthol, not only through hydrogen bonding via its hydroxyl groups but also due to the unique properties of its cyclic structure, with menthol as the guest molecule and β-cyclodextrin as the host molecule. It is not necessary to add a large amount; 0.2 to 1.0% by mass of the total mass of the main composition of the stick-type heated aroma-generating base material is sufficient. β-dextrin is also a type of polysaccharide and does not adversely affect the flavor perceived in the mouth by the aroma components generated from the material containing aroma components upon heating.

[0059] Furthermore, it is preferable to add microcrystalline cellulose to the stick-type heated fragrance generating substrate composition to assist in retaining the fragrance. This makes the following molding process more stable. As will be described later, after the process of forming a stick-type heated fragrance generating substrate sheet from the stick-type heated fragrance generating substrate composition, there is a process of cutting the sheet into prismatic, cylindrical, and granular shapes in order to preferably attract fragrance components and aerosols, and a process of wrapping these into stick shapes with packaging material. Roll molding and press molding are used as molding methods, but in any case, a large compressive force is applied to the composition from a metal such as stainless steel. At this time, this compressive force causes cohesive failure of the composition, adhesion to the metal, etc., making the molding process difficult. As a way to solve this problem, it is preferable to add microcrystalline cellulose.

[0060] Conventionally, high-purity microcrystalline cellulose, obtained by hydrolyzing and purifying pulp with acid, has been used as an excipient for pharmaceutical tablet molding because it is a fluid powder that does not dissolve in organic solvents such as water and ethanol. This is because the fluidity and high compressibility of microcrystalline cellulose, which result in large volume changes, are effective in preventing cohesive failure and adhesion to the mold during tablet molding by direct compression. In the present invention, by adding microcrystalline cellulose, for example, in the formation of sheets by roll molding with a three-roll system, and in the cutting of sheets by press molding, etc., cohesive failure of the sheet and adhesion to metal can be effectively prevented.

[0061] The microcrystalline cellulose preferably has an average particle size of 30 to 200 μm, and only needs to be added in an amount sufficient to support the retaining material. It is preferable to add 1.0 to 5.0% by mass of the total mass of the main composition of the stick-type heated aroma-generating base material. Microcrystalline cellulose does not adversely affect the flavor perceived in the mouth due to the aroma components generated from the material containing aroma components upon heating.

[0062] Furthermore, since this is a stick-type heated aroma-generating base material composition using various parts of non-tobacco plants, it is preferable to add an antibacterial preservative, which should be added in an amount of 0.005 to 0.04% by mass of the total mass of the main composition of the stick-type heated aroma-generating base material. Potassium sorbate and / or sodium benzoate are preferred as the antibacterial preservative.

[0063] Finally, inorganic particles may be added to the stick-type heated fragrance generating substrate composition of the present invention. This is because a heated fragrance generating substrate prepared with added inorganic particles will have less residue adhering to the heat source of a heated smoking device compared to a heated fragrance generating substrate without added inorganic particles. The amount of inorganic particles added is preferably 0.05 to 10 parts by mass, and more preferably 0.1 to 5 parts by mass, relative to the total mass of the main composition of the stick-type heated fragrance generating substrate.

[0064] This effect is not largely limited by the material or particle size of the inorganic particles, and was observed with 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; titanates such as potassium titanate and magnesium titanate; and even silicon oxides such as zeolites, colloidal silica, and fumed silica. Among these, magnesium carbonate, calcium carbonate, silicon oxide, and alumina are preferred. The reason for this is not clear, but possible explanations include the inorganic particles polishing the surface of the heat source during desorption from the heat source, and a decrease in the contact area between the heat source and the heated aromatic material during heating.

[0065] The above describes in detail the stick-type heated fragrance generating substrate composition. Using the materials that make up this composition, the stick-type heated fragrance generating substrate is molded in the following process and then assembled into a fragrance cartridge.

[0066] The materials containing the fragrance components to be used are sterilized at high temperature and then pulverized. If a retaining agent is used in this process, it is similarly sterilized at high temperature and then pulverized. Next, a predetermined amount of the materials containing the fragrance components and an adsorbent are dry-mixed in a dry mixer such as a tumbler mixer. Then, a predetermined amount of aerosol former and pure water are added to the dry-mixed raw materials and wet-mixed in a wet mixer such as a kneader. In this process, if necessary, a predetermined amount of retaining agent, thickener, β-cyclodextrin, microcrystalline cellulose, antimicrobial preservative, and inorganic particles are wet-mixed. This dispersion is formed into a sheet using a roll molding machine such as a three-roll press. This sheet is cut into a columnar shape, wound with packaging material, and then cut to a predetermined length to form a stick. The sticks manufactured in this way are dried and attached to multiple ends of a support member to which a mouthpiece is attached, and then assembled into a fragrance cartridge with packaging material. This process is similar to the manufacturing process of conventional stick-type e-cigarette cartridges. As a result, a stick-type heated fragrance body is obtained, characterized by using the stick-type heated fragrance generating base material composition of the present invention, and a fragrance cartridge is obtained, characterized by using this stick-type heated fragrance body. [Effects of the Invention]

[0067] According to the present invention, the product does not contain tobacco components and, like liquid-type e-cigarettes, allows users to enjoy a variety of flavors, such as beverages like coffee, cola, and Red Bull; desserts like chocolate, vanilla, and cream; fruits like orange, lemon, and melon; and cooling agents like menthol, mint, and herbs. The product does not contain tobacco or related plants of the Solanaceae family, nor any of their components. It provides a stick-type e-cigarette that strongly conveys the "flavor"—the aroma felt throughout the mouth when the heated aroma-generating base material is inhaled along with the aerosol—and has a form and smoking method highly similar to conventional cigarettes.

[0068] Therefore, this invention allows not only experienced smokers but also first-time smokers to enjoy a variety of "flavors" such as coffee, cola and other beverages, chocolate, vanilla and cream and desserts, oranges, lemons and melons and other fruits, and menthol, mint and herbs and other cooling agents, in a way that feels like smoking a cigarette, and to find peace of mind and body.

[0069] Furthermore, because the present invention is a harmless fragrance derived from plants that do not contain tobacco or related plants belonging to the Solanaceae family, it has the effect of not having any adverse health effects not only on the smoker themselves but also on non-smokers around them.

[0070] Therefore, the present invention does not merely replace conventional stick-type e-cigarettes, but rather provides a new fragrance cartridge that allows users to enjoy a variety of "flavors" such as beverages like coffee and cola, desserts like chocolate, vanilla, and cream, fruits like orange, lemon, and melon, and cooling agents like menthol, mint, and herbs, all in a cigarette-like manner. It also has a calming effect by inducing alpha waves in the brain, contributing to improved health and beauty. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0072] The present invention will be described in more detail below using embodiments, but the present invention is not limited thereto and can be implemented with various modifications without departing from the spirit of the invention, and is limited only to the technical concept described in the claims.

[0073] ≪Raw materials≫ The main composition of the stick-type heated aroma-generating base material consisted of roasted coffee beans as a material containing aroma components and a large amount of lipophilic oils and fats, cross-linked PVP as an adsorbent, dried rice straw as a retaining material, and propylene glycol and diethylene glycol as aerosol formers. The additives used were xanthan gum as a thickener, β-cyclodextrin as an adsorption aid, potassium sorbate as an antimicrobial preservative, and pure water.

[0074] Manufacturing of stick-type heated fragrance generating base material composition The manufacturing process was carried out according to steps M1 to M4 in Figure 1. In step M1, roasted coffee beans and straw were dried and ground. In step M2, predetermined amounts of the ground roasted coffee beans and straw, cross-linked PVP, aerosol former, xanthan gum, β-cyclodextrin, potassium sorbate, and pure water were weighed out. Then, in step M3, the ground roasted coffee beans, straw, and cross-linked PVP were dry-mixed in a tumbler mixer, and then in step M4, the aerosol former, xanthan gum, β-cyclodextrin, potassium sorbate, and pure water were added and wet-mixed in a kneader to produce a stick-type heated aroma-generating base material composition.

[0075] Manufacturing of stick-type heated fragrance generating substrates. The stick-type heated fragrance generating substrate composition manufactured in this manner was formed in step M5 using a three-roll molding process to a sheet thickness of 0.28 ± 0.02 mm. In step M6, the formed sheet was cut to a width of 1.5 ± 0.1 mm, and in step M7, it was wrapped in paper to a predetermined filling rate to form a stick. Next, in step M8, the paper-wrapped stick-type heated fragrance generating substrate composition was cut to a length of 11.5 to 12.0 mm, and in step M9, it was dried until the moisture content was 8 to 10% by mass, thereby manufacturing the stick-type heated fragrance generating substrate.

[0076] ≪Manufacturing of fragrance cartridges≫ As shown in Figures 2 and 3(A), the manufactured stick-type heated fragrance source 110, support member 120, and mouthpiece 140 were connected in this order in the X direction, and a fragrance cartridge 100 was manufactured using a packaging member 150. Alternatively, as shown in Figures 2 and 3(B), the manufactured stick-type heated fragrance source 110, support member 120, cooling member 130, and mouthpiece 140 were connected in this order in the X direction, and a fragrance cartridge 101 was manufactured using a packaging member 150.

[0077] ≪Structure of the fragrance cartridge≫ The support member 120 used here is connected to support the stick-type heated fragrance source 110, and its central part 121 is located along the central axis in the X direction of the fragrance cartridge 100, and it has a plurality of side parts 122. These plurality of side parts 122 extend outward from the central part 121 and are in contact with the packaging member 150 located at the periphery of the fragrance cartridge 100, and are fixed to the inner surface of the packaging member 150 with adhesive, thereby maintaining the strength of the fragrance cartridge 100.

[0078] ≪Structure of a stick-type heated fragrance generating substrate≫ The heated aroma source 110, which is an assembly of heated aroma-generating substrates 111, has a structure that allows smokers to inhale a stable airflow. Its internal structure will be explained using a heated aroma source 110 in which the heated aroma-generating substrates 111 are wrapped in a packaging member 150 as an example. Figure 4 shows a schematic diagram of its cross-section. When the heated fragrance-generating substrates 111 aggregate, numerous heated fragrance-generating substrate aggregates 1112 are formed. Within these heated fragrance-generating substrate aggregates 11112, gas channels are formed such as gas channels 1113A within the heated fragrance-generating substrate aggregates created by the misalignment of the individual heated fragrance-generating substrates 1111, gas channels 1113B between the heated fragrance-generating substrate aggregates 1112, gas channels 1113C between the individual heated fragrance-generating substrates 1111 and the heated fragrance-generating substrate aggregates 1112, and gas channels 1113D between the heated fragrance-generating substrates 111 and the packaging member 150. As a result, volatile substances generated by heating pass through these gas channels, allowing smokers to inhale fragrance and smoke with a stable airflow.

[0079] ≪How to use the fragrance cartridge≫ When a smoker uses the device, as shown in Figure 5, they attach the fragrance cartridge 100 (or 101) to the mounting section 210 of the heated smoking device body 200. A heat source 211 located in the center of the bottom of the mounting section 210 pierces the stick-shaped heated fragrance generating base material 110, heating the base material 111 and allowing the smoker to enjoy smoking.

[0080] Evaluation of stick-type heated fragrance generating substrates. Ten subjects evaluated the aroma emanating from the stick-type heated aroma-generating substrates, manufactured from the various stick-type heated aroma-generating substrate compositions shown in Table 1, using the heated smoking device shown in Figure 5. Seven or more subjects judged the substrate as a pass (○) if they perceived a pleasant coffee aroma as a "flavor" throughout their oral cavity, and as a fail (×) otherwise. On the other hand, in the process of manufacturing the stick-type heated aroma-generating substrates from the various stick-type heated aroma-generating substrate compositions shown in Table 1, the substrate was judged as a pass (○) if there was no detachment of crushed coffee beans, or defects or breakage of the sheet, and as a fail (×) if such defects occurred.

[0081] ≪Results≫ In Examples 1 to 8, which are various stick-type heated aroma-generating base material compositions of the present invention, all passed both sensory and molding tests. However, in Comparative Examples 1 and 2, which exceeded the range of blending ratios of the present invention, neither the sensory nor the molding test was passed. Although not described in these examples, studies using materials containing large amounts of the aroma components disclosed in the present invention yielded good results, similar to roasted coffee beans. Although not described in these comparative examples, numerous other materials that could act as adsorbents or retainers were investigated, but no preferred materials other than those disclosed in the present invention were found.
