Description

Smoking articles and aerosol generating devices using the same

[0001] The present invention relates to a smoking article and an aerosol generating device using the same, and more particularly, to a smoking article and an aerosol generating device using the same, which can improve a user's smoking experience by including an aerosol generating segment in which nicotine, a flavoring agent, and an aerosol generating material are formed in a solid form.

[0002] Demand for so-called electronic cigarettes, which provide users with a smoking experience through heating methods other than combustion, has been steadily increasing, and technological development to address this demand is also actively underway. Among the various smoking devices, cartridges containing liquid solvents have been inserted into devices for use in conjunction with heat-not-burn tobacco, while single-use, disposable heat-not-burn tobacco devices that incorporate a moisture-absorbing material have also been developed.

[0003] Meanwhile, to improve the user's odor (aroma) or smoking experience upon inhalation, separate flavoring agents or active ingredients such as nicotine can be added. These substances can vary depending on their type, but they can also be prone to high volatility, oxidation, or deterioration. Furthermore, if they are liquid or solid with a low melting point, they become fluid as the temperature rises. Therefore, when applied to e-cigarettes, they require a plastic container, such as a liquid cartridge, which poses a risk of leakage during use. Furthermore, there is a pressing need for technology to ensure that these volatile, oxidized, and / or deteriorating substances are delivered intact to the user.

[0004] The technical problem to be solved by the present invention is to provide a smoking article and an aerosol generating device using the same, which can completely deliver flavoring, nicotine, and aerosol generating material that are liquid at room temperature or solid with a low melting point to a user without worrying about leakage or the like.

[0005] The technical problems of the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0009] In some embodiments of the present invention, the aerosol-generating segment may include a nicotine-generating portion and a flavor-generating portion arranged adjacent to each other in the longitudinal direction, wherein the nicotine-generating portion may include a first solid body formed of nicotine and an aerosol-generating material by a thickener, and the flavor-generating portion may include a second solid body formed of a flavor and an aerosol-generating material by a thickener.

[0010] In some embodiments of the present invention, the device may further include a tube through which the aerosol passes and is cooled; and a filter for filtering the aerosol and delivering it to the user.

[0011] In some embodiments of the present invention, the tube includes an airflow passage therein through which the aerosol passes. Fragments of the solid body of the flavoring agent and the aerosol-generating material may be applied onto the surface of the airflow passage.

[0012] In some embodiments of the present invention, the thickener comprises a first thickener for forming the nicotine into a solid, and a second thickener for forming the flavoring into a solid, wherein the first thickener and the second thickener may be the same or different from each other.

[0013] In some embodiments of the present invention, the aerosol-generating segment comprises a first section in the center and a second section surrounding the first section, wherein the distribution of the solid in the first section and the second section may be different from each other.

[0014] In some embodiments of the present invention, the aerosol-generating segment comprises an absorbent material coated with the nicotine, flavoring agent, thickener, and aerosol-generating material, wherein the absorbent material may comprise at least one of pulp fabric, woven cotton fabric, non-woven fabric, woven bamboo fiber fabric, and porous ceramic.

[0036] The advantages and features of the present invention, and the methods for achieving them, will become clearer with reference to the embodiments described in detail below together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms. These embodiments are provided only to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Like reference numerals designate like elements throughout the specification.

[0037] When one component is referred to as being "connected to" or "coupled to" another component, it includes both cases where it is directly connected or coupled to the other component, or cases where there is another component intervening therebetween. Conversely, when one component is referred to as being "directly connected to" or "directly coupled to" another component, it indicates that there is no other component intervening therebetween. "And / or" includes each and any combination of one or more of the mentioned items.

[0038] The terminology used herein is for the purpose of describing embodiments only and is not intended to limit the present invention. In this specification, the singular also includes the plural unless specifically stated otherwise. As used herein, the terms "comprises" and / or "comprising" do not exclude the presence or addition of one or more other components, steps, operations, and / or elements.

[0039] Although terms like "first" and "second" are used to describe various components, these components are not limited by these terms. These terms are merely used to distinguish one component from another. Therefore, it should be understood that a "first" component referred to below may also be a "second" component within the technical scope of the present invention.

[0040] Unless otherwise defined, all terms (including technical and scientific terms) used herein may be used in their common sense to those of ordinary skill in the art to which the present invention pertains. Furthermore, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise.

[0041] As used herein, "aero" refers to fine solid or liquid particles suspended in the atmosphere. In electronic cigarettes, the components are vaporized through heating, then condensed into an aerosol for inhalation.

[0042] As used herein, "electronic cigarette" or "e-cigarette" refers to an electronic inhaler that simulates the effects of smoking. Many e-cigarettes are completely different from conventional cigarettes. The amount of nicotine contained can be selected by the user through inhalation. Typically, an e-cigarette comprises three essential components: a cartridge, which acts as a mouthpiece and a container for storing the formulation, a heater, and a battery.

[0043] Hereinafter, four representative embodiments of the present invention will be described with reference to the drawings.

[0044]

[0045] [Example 1]

[0046] FIG. 1 is a drawing for explaining a smoking article according to a first embodiment of the present invention.

[0047] Referring to FIG. 1, a smoking article (10) according to a first embodiment of the present invention may include an aerosol generating segment (110), a tube (120), and a filter (130).

[0048] The aerosol generating segment (110) may include a solid body containing nicotine, a flavoring agent, a thickener, and an aerosol generating material. That is, the nicotine, the flavoring agent, and the aerosol generating material may be formed into a solid body by the thickener, and such a solid body may be included in the aerosol generating segment (110) in a state of being applied to an absorbent material or the like, and may be vaporized when the active ingredient generating unit (111) is heated and inhaled by the user in the form of an aerosol.

[0049] Nicotine is an alkaloid molecule containing two basic nitrogen atoms. It is a chemical stimulant that increases heart rate and blood pressure when administered to an individual or animal. Nicotine's delivery to an individual is associated with physical and / or emotional satisfaction. Nicotine can occur in different states of protonation. For example, if no protonation occurs, nicotine is referred to as "free-base nicotine." If one nitrogen is protonated, nicotine is "mono-" protonated, and if two nitrogens are protonated, nicotine is "di-" protonated. The nicotine can be naturally occurring nicotine (e.g., an extract of a nicotine species such as tobacco) or synthetic nicotine. The nicotine can be (-)-nicotine, (+)-nicotine, or a mixture thereof. The nicotine is used in a relatively pure form (e.g., having a purity of greater than about 80%, 85%, 90%, 95%, or 99%). The nicotine is "colorless and transparent" in appearance to minimize or avoid the formation of tar residue.

[0050] The above "free-base nicotine" refers to the unprotonated nicotine molecule. It is also called nicotine or stem nicotine.

[0051] The above "Nicotine Salt" is formed by combining the basic molecule, free base nicotine, with an acid component, and as shown in the following chemical formula 1, when nicotine and an acid component combine in an aqueous solution, the pH is lowered and the free base or unprotonated nicotine molecule changes into one of two protonation forms, such as monoprotonated and diprotonated.

[0052]

[0053] The above monoprotonated nicotine salt is nonvolatile, exists in a liquid state in aerosol droplets, and has a pK a1 = 3.12 ≤ pH ≤ pK a2 = 8.02, it is acidic (positively charged), is absorbed slowly from the lungs, has a high inhaled concentration, has a low impact, and has a low unpleasant taste. Deprotonated nicotine salts, such as nicotine salts using tartaric acid, can also be used, and pK a1 = pH ≥ 3.12. On the other hand, the free base nicotine is volatile and returns to the gaseous state in the aerosol droplets, and pH > pK a2 = 8.02, it is neutral (uncharged), rapidly absorbed from the oral cavity and upper bronchial tubes, has low inhalation concentration, high impact, and high unpleasant taste.

[0054] The above "acid component" is a component added to change free-base nicotine into nicotine salt, and includes carboxylic acid, sulfinic acid, sulfonic acid, alcohol, amino acid, phenol, thiophenol, oxime, enol, imide, aromatic sulfonamide, primary nitro compound, secondary nitro compound, other organic acids and inorganic acids, or derivatives processed like esters, or naturally occurring derivatives, or a combination including at least one of these.

Aerosol-generating substances are monovalent with one -OH group, divalent with two -OH groups, trivalent with three -OH groups, and polyvalent with two or more -OH groups.

[0062] An example of the above monovalent substance may be alcohol (monohydric alcohol), and examples thereof include methanol, ethanol, isopropyl alcohol (Propan-2-ol), butanol (Butan-1-ol), pentanol (Pentan-1-ol), and cetyl alcohol (Hexadecan-1-ol).

[0066] The target ingredient to be inhaled in aerosol form, included in the aerosol generating segment (110), can exist as a liquid at room temperature, and when applied to an electronic cigarette, a container such as a liquid cartridge is required. Consequently, problems with the application of a plastic container and leakage exist, and the active ingredient may volatilize, oxidize, and / or deteriorate. Therefore, the smoking article (10) of the present invention forms the target ingredient into a solid using a thickener, thereby eliminating concerns about leakage and ensuring the complete delivery of the active ingredient to the user.

[0067] Specifically, the solid formed by the thickener is a solid at room temperature, and when heated, only the desired aerosol component is released and delivered to the user. Meanwhile, the thickener that solidifies the liquid remains without being vaporized when heated. Accordingly, volatilization, oxidation, and / or deterioration of the target component to be inhaled in the form of an aerosol can be prevented, and it can be delivered intact to the user. In addition, the smoking article (10) includes the solid in a form absorbed by a hygroscopic material and is manufactured to be used once and then thrown away, thereby increasing the ease of storage and use, and has the advantages of being environmentally friendly since it does not use a plastic container such as a liquid cartridge, having a low difficulty in the manufacturing process, and making it easy to secure an airflow path.

[0068] Additionally, the effect of reducing the length and weight of the smoking article (10) can be achieved by including nicotine, flavoring agent and aerosol generating material within a single aerosol segment (110).

[0069] Finally, there is also the advantage of being able to apply the smoking article by modifying it in various ways, as shown in the additional embodiments of FIGS. 2a to 5b described below.

[0070] The above thickener is a substance necessary to solidify an aerosol-generating substance (liquid) and has hydrophilicity (or partial hydrophilicity). Generally, it has the property of increasing the viscosity of the solution when added. The aerosol component that you want to inhale from an e-cigarette has a hydrophilic functional group (-OH) or a hydrophilic part, so in order to contain it, the thickener must also have a hydrophilic functional group (-OH, -NH2, -COOH, etc.) or a hydrophilic part. In order to prevent vaporization when heated, a polymer form with a large molecular weight is suitable. The hydrophilic group of the hydrophilic polymer (thickener) and the hydrophilic group of the aerosol component interact through hydrogen bonds, and the aerosol component enters between the hydrophilic polymers, so that the component that is liquid at room temperature can be solidified.

[0071] The thickeners include, for example, alkylcelluloses, such as methylcellulose; hydroxyalkylcelluloses, such as hydroxymethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, and hydroxybutylcellulose; hydroxyalkyl alkylcelluloses, such as hydroxyethyl methylcellulose and hydroxypropyl methylcellulose; microcrystalline cellulose; carboxyalkylcelluloses, such as carboxymethylcellulose; alkali metal salts of carboxyalkylcelluloses, such as sodium carboxymethylcellulose; carboxyalkylalkylcelluloses, such as carboxymethylethylcellulose; carboxyalkylcellulose esters; starch; pectins, such as sodium carboxymethylamylopectin; chitin derivatives, such as chitosan; At least one selected from the group consisting of monosaccharides, disaccharides, oligosaccharides and polysaccharides, such as trehalose, cyclodextrins and derivatives thereof; alginic acid, carrageenan, galactomannan, tragacanth, agar, gum arabic, guar gum and xanthan gum; polyacrylic acid and salts thereof; casein, gelatin, keratin, albumin, collagen, glutelin, glucagon, gluten, zein and shellac; polymethacrylic acid, salts and esters thereof, methacrylate copolymers; polyvinylpyrrolidone (PVP), polyvinyl alcohol (PVA), polyethylene glycol, polyglutamic acid, polyvinylpyrrolidone, polyethyleneimine, polyacrylic acid, sodium polyacrylate, polyacrylamide, acid-polymerized polymers, urea polymers, polymers produced through polymerization reactions and copolymers thereof.

[0072] The polymer produced through the above polymerization reaction is a substance having multiple bonds such as a double bond or a triple bond, or a substance having high reactivity and produced by other polymerization reactions, such as acrylic acid, methacrylic acid, butyl methacrylic acid, acrylamide, dimethylacetamide, formamide, methacrylamide, sodium amide, sulfanilamide, nicotinamide, urea, vinyl alcohol, vinylpyrrolidone, etc., monomers, dimers, multimers, high molecular substances having multiple bonds, etc., correspond to reactants, and the polymer produced through the reaction is a polymer composed of various combinations of monomers corresponding to reactants, including polyacrylic acid, sodium polyacrylate, polyacrylamide, polyvinyl alcohol, polyvinylpyrrolidone, etc., or a combination of polymers in which the reaction is completed.

[0084] Meanwhile, in some embodiments of the present invention, the thickener for forming a flavoring agent into a solid form and the thickener for forming a nicotine or aerosol-generating substance into a solid form may be the same or different. Hereinafter, the thickener for solidifying a flavoring agent, i.e., a "flavoring-only thickener," and the thickener for solidifying nicotine, i.e., a "nicotine-only thickener," are described.

[0085] For example, a nicotine-only thickener means a thickener capable of trapping nicotine in a free-base nicotine state, and may be, for example, one or more selected from the group consisting of cyclodextrins (alpha, beta or gamma), microcrystalline cellulose and derivatives thereof.

[0086] Cyclodextrin is a compound whose interior is hydrophobic and its exterior is hydrophilic. When reacted with nicotine, one nicotine molecule reacts with one cyclodextrin molecule, forming a complex in which one nicotine molecule is embedded within the cyclodextrin. Because the exterior of cyclodextrin is hydrophilic, it can bind to a thickening agent for solidification. When the polarity difference and molecular size are appropriate, a 1:1 complex is formed, forming a complex in which a nicotine molecule is embedded within the cyclodextrin at a 1:1 molar ratio.

[0087] The above microcrystalline cellulose is a porous compound. It has a large specific surface area (a large surface area-to-volume ratio) and possesses both hydrophilic and hydrophobic moieties, so van der Waals forces act, forming hydrogen bonds between the -OH groups of cellulose and nicotine. This effectively traps nicotine within the porous structure of microcrystalline cellulose. The large surface area-to-volume ratio is advantageous for van der Waals forces. It is absorbed and adsorbed within the porous structure. Hydrogen bonds are formed between the -OH groups within the cellulose molecules and the nicotine molecules. After solvent removal, nicotine is adsorbed within the internal space.

[0088] In some embodiments of the present invention, when the flavoring-only thickener and the nicotine-only thickener are different, the flavoring and nicotine may be solidified by the different thickeners, and then the solid body may be manufactured using the aerosol-generating material and the common thickener, thereby being included in the aerosol-generating segment (110).

[0089] Alternatively, if the flavoring-only thickener and the nicotine-only thickener are the same but different from the thickener for solidifying the aerosol-generating material, the flavoring and nicotine may be solidified by the flavoring or nicotine-only thickener, and then a solid body may be manufactured using the common thickener with the aerosol-generating material, thereby being included in the aerosol-generating segment (110).

[0090] Finally, if the flavoring-only thickener, the nicotine-only thickener, and the thickener for solidifying the aerosol-generating material are all the same, the flavoring, nicotine, and aerosol-target material may be mixed with the thickener to produce a solid, thereby being included in the aerosol-generating segment (110).

[0091] In this way, the smoking article (10) according to the embodiment of the present invention can select various types of thickeners according to the types of flavoring agent, nicotine, and aerosol-generating material included in the aerosol-generating segment (110) and use them for each solidification.

[0092] In some embodiments of the present invention, the aerosol-generating segment (110) may include an absorbent material in which nicotine, a flavoring agent, and a solid aerosol-generating material are absorbed, coated, or dispersed. The absorbent material may be formed, for example, by crumpling, folding, or rolling pulp or a fabric comprising pulp, a woven cotton fabric, a non-woven fabric, or a woven bamboo fiber fabric into a cylindrical shape or by processing the same into a cylindrical shape. In some other embodiments, the absorbent material may include a porous ceramic.

[0093] These absorbents can further reduce the possibility of leakage by solidifying as a thickener within the aerosol generating segment (110) to absorb, coat or disperse and integrate the contained nicotine, flavoring and aerosol generating material.

[0094] In some embodiments of the present invention, the aerosol-generating segment (110) may further comprise a surfactant to prevent the solid form of nicotine, flavoring agent, and aerosol-generating material from being firmly bound or further reacting with the external environment.

[0095] These surfactants may further include one or more surfactants selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, and zwitterionic surfactants, and may have the effect of strengthening the bond or preventing reaction with other substances, deterioration due to temperature, and deterioration due to moisture. The degree of hydrophilicity, amphotericity, or hydrophobicity of the surfactant is selected and used in a type and amount so as to exhibit the desired properties depending on the type of aerosol target substance, nicotine salt, and thickener used, and the physical and chemical characteristics, thereby allowing the strength of the bonding force to be controlled. By adding a surfactant when manufacturing a combination of a thickener and an aerosol target substance (solid), the bonding strength can be controlled, or the role of a protective film against the external environment can be expected. Surfactants are structures that have both hydrophilic and hydrophobic parts. The hydrophilic part is directed toward the aerosol target substance and hydrophilic polymer, and the hydrophobic part is exposed to the external environment. It is expected to act as a barrier against the leakage of the hydrophilic polymer or reactions from the external environment such as moisture and temperature changes. In addition, the hydrophobic part of the surfactant interacts with the hydrophobic part of the thickener, and the hydrophilic part of the surfactant forms a bond with the aerosol target substance to form a more solid body.

[0096] The binding strength and expected effect of a surfactant depend on the ratio and structure of the hydrophilic and hydrophobic portions. The larger or longer the hydrophobic portion, the thicker the protective film formed on the outside of the solid body. In addition, the density and thickness of the hydrophobic portion may affect the ability of the hydrophilic aerosol target substance to penetrate the hydrophobic film component when vaporized by heating. The degree to which the hydrophobic film's rigidity is disturbed (depending on its fluidity) during heating may vary the degree to which the aerosol component escapes. The closer the hydrophobic portion's structure is to a chain-like structure and its length, the stronger the bond between the hydrophobic portions, increasing the rigidity of the hydrophobic film. In addition, if the hydrophobicity is too strong, the bond with the hydrophilic solid body will not be strong. It is desirable to select a material that can easily escape when the aerosol target component is vaporized by heating and that can act as a protective film against the external environment, and that has structural properties suitable for this.

[0101] FIGS. 2A and 2B are drawings for explaining various configurations of an aerosol-generating segment in a smoking article according to a first embodiment of the present invention. FIG. 2A is a cross-sectional view of the aerosol-generating segment (110) of FIG. 1 taken along line AA'.

[0102] Referring to FIG. 2A, the aerosol generating segment (110) may include a plurality of sections (111, 112) separated in the thickness direction of the cross-section. The first section (111) and the second section (112) may extend in the longitudinal direction of the smoking article (10). As illustrated in FIG. 2A, the first section (111) may be positioned more centrally than the second section (112), and the second section (112) may surround the side of the first section (111).

[0103] In some embodiments of the present invention, the distribution of the solids of nicotine, flavoring agent, and aerosol-generating material included in the aerosol-generating segment (110) may vary depending on the location within the aerosol-generating segment (110). For example, the heating temperature within the aerosol-generating segment (110) may vary depending on the distance from the heat source that heats the aerosol-generating segment (110). When the smoking article (10) is heated from the outside of the receiving portion into which the smoking article (10) is inserted, the temperature of the first section (111) located relatively centrally in the cross-sectional direction of the aerosol-generating segment (110) may be formed to be lower than that of the second section (112). At this time, in order to increase the amount of aerosol emitted from the central portion, the first section (111) of the aerosol-generating segment (110) may have a solid distribution with an increased concentration than that of the second section (112).

[0104] Alternatively, if a heating rod is inserted into the aerosol generating segment (110) and heated, the temperature of the second section (112) may be formed lower than that of the first section (111) in the cross-sectional direction of the aerosol generating segment (110) in contrast to the above. Accordingly, in order to increase the amount of aerosol emitted from the outer portion, the second section (112) of the aerosol generating segment (110) may have a solid distribution with an increased concentration than that of the first section (111).

[0105] Referring to FIG. 2b, the aerosol generating segment (110) may include a plurality of longitudinally separated sections (113, 114). As illustrated in FIG. 2b, the first section (113) may be positioned more proximal to the user than the second section (114).

[0106] In some embodiments of the present invention, the distribution of the solids located in the first section (113) and the second section (114) may be different. For example, since the aerosol generated from the first section (113) of the proximal portion reaches the user first when smoking, the solids of the flavoring agent and the aerosol-generating agent may be applied and included in the first section (113), and the solids of the nicotine and the aerosol-generating agent may be applied in the second section (114). This may enhance the smoking experience by allowing the user to inhale the flavoring agent before the bitter taste of nicotine reaches the user.

[0107] Alternatively, a smoking method may be possible in which materials having different vaporization temperatures are applied to the first section (113) and the second section (114), and the heating temperatures of the first section (113) and the second section (114) are heated differently.

[0108] FIGS. 3A and 3B are drawings for explaining the configuration of a wrapper that wraps a filter, a tube, and an aerosol generating segment in a smoking article according to the first embodiment of the present invention.

[0109] Referring to FIG. 3A, the wrapper (140) may encapsulate each of the components by surrounding at least a portion of the aerosol generating segment (110), the tube (120), and the filter (130). The wrapper (140) may be, for example, a roll of paper, and in some embodiments, the wrapper (140) may comprise a porous roll of paper.

[0110] Meanwhile, as described above, since nicotine, flavoring agent, and aerosol-generating material are formed in a solid form in the aerosol-generating segment (110), leakage to the outside of the aerosol-generating segment (110) can be prevented as much as possible, but since the wrapper (140) wraps the aerosol-generating segment (110), nicotine, flavoring agent, and aerosol-generating material before being aerosolized by heating can be prevented from escaping to the outside of the aerosol-generating segment (110).

[0111] In addition, the wrapper (140) can prevent the aerosol generating segment (110), tube (120), and filter (130) from burning during the heating process by the aerosol generating device by including a non-combustible material.

[0112] Meanwhile, in some embodiments of the present invention, a flavoring agent may be applied to at least a portion of the wrapper (140). When the smoking article (10) is heated, the wrapper (140) may also be indirectly heated. When the wrapper (140) is heated, the flavoring agent applied to the wrapper (140) may be mixed with the aerosol generated from the aerosol generating segment (140) and delivered to the user through inhalation.

[0113] Therefore, the user's smoking experience can be improved by obtaining an additional flavoring effect by the wrapper (140) in addition to the aerosol generating segment (110).

[0114] Referring to FIG. 3b, the wrapper (140) may include a first portion (141) surrounding the aerosol generating section (110), a second portion (142) surrounding the tube (120), and a third portion (143) surrounding the filter (130). The first to third portions (141 to 143) may be separated from each other by physically separate sheets, but the present invention is not limited thereto.

[0115] (a) of FIG. 3b illustrates a configuration in which a flavoring agent is applied to a third portion (143) surrounding a filter (130), (b) illustrates a configuration in which a flavoring agent is applied to a second portion (142) surrounding a tube (120), (c) illustrates a configuration in which a flavoring agent is applied to the second and third portions (142, 143) surrounding a filter (130) and a tube (120), and (d) illustrates a configuration in which a flavoring agent is applied to the entire wrapper (140).

[0116] In this way, the smoking article (10) according to embodiments of the present invention can provide a rich amount of smoke and improve the user's smoking experience by allowing the wrapper (140) to additionally supply a flavoring ingredient.

[0117] FIGS. 4a and 4b are drawings for explaining the structure of a smoking article according to a modification of the first embodiment of the present invention.

[0118] Referring to FIG. 4a, a smoking article (20) according to the present invention includes an aerosol generating segment (210), a tube (220), and a filter (230), wherein a flavoring agent may be applied to the surface of an airflow passage (221) formed inside the tube (220). When the aerosol generated from the aerosol generating segment (210) is transmitted through the tube (220), it may be mixed with the flavoring agent applied to the airflow passage (221) to provide an additional flavor to the user. This allows the user's smoking experience to be enhanced by obtaining the flavoring effect by the tube (220) in addition to the aerosol generating segment (210).

[0119] Meanwhile, in some embodiments of the present invention, the smoking article (20) of FIG. 4A may also include a wrapper (240) that wraps the aerosol-generating segment (210), the tube (220), and the filter (230) as in the previously described embodiment, and a flavoring agent may be applied to the wrapper (240) divided into first to third parts (241 to 243) corresponding to each segment. FIG. 4B (a) illustrates a configuration in which a flavoring agent is applied to the third part (243) surrounding the filter (230), (b) illustrates a configuration in which a flavoring agent is applied to the first and third parts (241, 243) surrounding the aerosol-generating segment (210) and the filter (230), and (c) illustrates a configuration in which a flavoring agent is applied to the entire wrapper (240).

[0120] In this way, the smoking article (20) according to embodiments of the present invention can enhance the user's smoking experience by providing additional flavor through the tube (220) and wrapper (240).

[0121] FIGS. 5a and 5b are drawings for explaining the structure of a smoking article according to another modification of the first embodiment of the present invention.

[0122] Referring to FIG. 5a, a smoking article (30) according to the present invention includes an aerosol generating segment (310), a tube (320), and a filter (330), wherein fragments (325) of a solid body of a flavoring agent and an aerosol generating material may be applied to the inner wall of an airflow passage (321) formed inside the tube (320). The fragments (325) of the solid body may be fixed to the inner wall of the airflow passage (321) by having a certain viscosity due to a thickener, and an aerosol may be generated from the fragments (325) of the solid body applied to the surface of the airflow passage (221) by being heated by the aerosol generated from the aerosol generating segment (210).

[0123] This can improve the user's smoking experience by obtaining additional smoke and flavoring effects through the tube (220) in addition to the aerosol generating segment (210).

[0124] Meanwhile, in some embodiments of the present invention, the smoking article (30) of FIG. 4A may also include a wrapper (340) that wraps the aerosol-generating segment (310), the tube (320), and the filter (330) as in the previously described embodiment, and a solid body of a flavoring agent and an aerosol-generating substance may be applied to the wrapper (340) divided into first to third parts (341 to 343) corresponding to each segment. FIG. 3B (a) illustrates a configuration in which a solid body of a flavoring agent and an aerosol-generating substance is applied to the third part (343) surrounding the filter (330), (b) illustrates a configuration in which a solid body of a flavoring agent and an aerosol-generating substance is applied to the first and third parts (341, 343) surrounding the aerosol-generating segment (310) and the filter (330), and (c) illustrates a configuration in which a solid body of a flavoring agent and an aerosol-generating substance is applied to the entire wrapper (340).

[0125] In this way, the smoking article (30) according to embodiments of the present invention can provide a rich amount of smoke and improve the user's smoking experience by additionally supplying aerosol from the tube (320).

[0126] FIGS. 6A and 6B are drawings for explaining an aerosol generating device using a smoking article according to the first embodiment of the present invention.

[0127] First, referring to FIG. 6A, an aerosol generating device (1000) according to the present invention is a device that generates an aerosol by heating by inserting a smoking article (10) of the present invention, and may include a receiving portion (1010) into which a smoking article (10, 20, 30) is inserted, a heater (1020) that heats the smoking article (10), a power supply portion (1030) that supplies power to the heater (1020), and a control portion (1040) that controls the heater (1020) and the power supply portion (1030). Other heated smoking devices (1000) may further include a sensor that detects a user's puff or an output portion that informs the user of the current status.

[0128] The heater (1020) may include, but is not limited to, a coil that heats the smoking article (10) from the outside by being positioned at a position corresponding to the aerosol generating segment (110) of the smoking article (10) on the outside of the receiving portion (1020), and, unlike that illustrated in FIG. 6A, may be configured to have the shape of a heating rod and be inserted into the aerosol generating segment (110) to transfer heat. In some embodiments of the present invention, the heater (1020) may heat the aerosol generating segment (110) to a temperature of 180° C. to 280° C.

[0129] Meanwhile, as illustrated in FIG. 6b, the heater (1020) of the smoking article may include a plurality of heaters, such as a first heater (1021) positioned proximal to the user and a second heater (1022) positioned distally. When the aerosol generating device (1000) is used, the first heater (1021) and the second heater (1022) may heat the aerosol generating segment (110) at different heating temperatures, and in particular, the operations of the first heater (1021) and the second heater (1022) may be configured to have different heating temperatures or heating times for a smoking article (10) including a first section (113) and a second section (114) divided in the longitudinal direction, as illustrated in FIG. 2b.

[0130] Figure 7 is a flowchart for explaining a method for manufacturing a smoking article according to the first embodiment of the present invention.

[0131] Referring to FIG. 7, a method for manufacturing a smoking article according to a first embodiment of the present invention may include a step of forming a solid of nicotine using a thickener (S110), a step of forming a solid of a flavoring agent using a thickener (S120), a step of forming a solid of nicotine and a solid of a flavoring agent together with an aerosol-generating material into a solid using a thickener (S130), a step of applying the formed solid to an absorbent material to manufacture an aerosol-generating segment (S140), and a step of forming a smoking article by rolling the aerosol-generating segment together with a filter and a tube into a wrapper (S150).

[0132] The above processes apply to cases where the nicotine-only thickener for solidifying nicotine and the flavor-only thickener for solidifying the flavor are different, respectively. In another embodiment, when the thickeners for solidifying nicotine and the flavor are the same, steps S110 and S120 can be performed simultaneously by mixing the nicotine and the flavor to form a solid.

[0133] In another embodiment, steps S110, S120 and S130 may be performed simultaneously by mixing the nicotine, flavoring agent and aerosol-generating agent to form a solid, when the thickening agent for solidifying the nicotine, flavoring agent and aerosol-generating agent are the same.

[0134] In some embodiments of the present invention, forming nicotine, a flavoring agent, or an aerosol-generating material into a solid using a thickener may be a step of forming a solid slurry by stirring and heating the nicotine, a flavoring agent, or an aerosol-generating material with distilled water (or a solution containing alcohol) using a thickener. This solid slurry may be in the form of a solid precipitated or dissolved in a solvent.

[0135] Depending on the type of thickener, some thickeners are insoluble in glycerin and propylene glycol, so they must be dissolved in solvents such as water, methanol, and ethanol to expose their hydrophilic functional groups. The exposed hydrophilic functional groups of the thickener and the hydrophilic functional groups of the aerosol target substance interact through hydrogen bonds, allowing the aerosol target substance to enter between the thickener polymer chains. The longer the polymer, the more bonds formed along the molecule, and the greater the energy required to break these bonds. In particular, smaller polar molecules such as water, ethanol, and methanol can easily insert themselves between the polymer chains than molecules such as glycerin and propylene glycol. Furthermore, solvents such as water, ethanol, and methanol have different molecular polarities from glycerin and propylene glycol, which may facilitate interaction depending on the type of thickener. The use of solvents to separate the thickener polymers is essential or convenient during manufacturing. Hydrophilic functional groups can be exposed by dissolving in a solvent and allowing them to interact with solvent molecules. The exposed functional groups then bind to the hydrophilic functional groups of the aerosol target substance through hydrogen bonding.

[0136] A solid slurry in which the solids of each component are precipitated or dissolved in a solvent can be applied to an absorbent material for the production of an aerosol-generating segment.

[0137] Afterwards, when the absorbent material coated with the solid slurry is dried, the solvent evaporates through drying, and an absorbent material is obtained in which the solid powders are distributed throughout the absorbent material.

[0138] The above drying can be performed on each solid of each component, but can also be performed after applying a solvent containing the final solids obtained by solidifying multiple components together to the absorbent.

[0139] The aerosol-generating segment is manufactured by processing the absorbent material coated with the solid material, such as rolling, compressing, or cutting it, depending on the type of absorbent material, and then this is used as a single rod and wrapped together with a filter and a tube to complete the final smoking article.

[0140] Hereinafter, smoking articles according to other embodiments of the present invention will be described with reference to FIGS. 8 to 14.

[0141]

[0142] [Example 2]

[0143] Figures 8a and 8b are drawings illustrating smoking articles according to other embodiments of the present invention. First, the second embodiment of the present invention will be described.

[0144] Referring to FIGS. 8a and 8b, a smoking article (10) according to a second embodiment of the present invention may include an aerosol generating segment (110), a tube (120), and a filter (130).

[0145] The aerosol generating segment (110) may include a solid body containing nicotine, a flavoring agent, a thickener, and an aerosol generating material. Meanwhile, in the smoking article (10) of the present invention, the aerosol generating segment (110) may be divided into an active ingredient generating portion (111) containing nicotine and a flavoring agent as a solid body, and an aerosol generating portion (112) containing the aerosol generating material as a solid body.

[0146] That is, compared to the first embodiment described above, in which the aerosol generating segment was comprised of only one region, in the second embodiment, this segment is divided into two regions, an active ingredient generating portion and an aerosol generating portion. The active ingredient generating portion of the second embodiment is composed of the same content as the aerosol generating segment of the first embodiment, and there is a difference in that an aerosol generating portion including a second solid body in which an aerosol generating substance is solidified by a thickener is added to constitute the aerosol generating segment.

[0147] Therefore, the description of the active ingredient generating unit of the second embodiment is replaced with the description of the aerosol generating segment of the first embodiment, and only the possible aerosol generating unit is described.

[0148] In addition, descriptions of nicotine, acid components, flavoring agents, aerosol-generating substances, thickeners, and surfactants, etc., are omitted if the descriptions of the first embodiment are equally applicable. This also applies to the descriptions of the third and fourth embodiments described below.

[0149] FIG. 8a illustrates a smoking article (10) of an embodiment in which an active ingredient generating unit (111) containing nicotine and a flavoring agent as a solid is disposed between an aerosol generating unit (112) and a tube (120), and FIG. 1b illustrates a smoking article (11) of an embodiment in which an aerosol generating unit (112) containing an aerosol generating material as a solid is disposed between an active ingredient generating unit (111) and a tube (120).

[0150] The active ingredient generating unit (111) may include a first solid body formed by a thickener of nicotine, a flavoring agent, and an aerosol generating material. This first solid body may be included in the active ingredient generating unit (111) in a state of being applied to an absorbent material or the like, and may be vaporized when the active ingredient generating unit (111) is heated and inhaled by the user in the form of an aerosol.

[0151] The aerosol generating unit (112) may include a second solid body formed by a thickener as an aerosol generating material. This second solid body may be included in the aerosol generating unit (112) in a state of being applied to an absorbent material or the like, and may be vaporized when the aerosol generating unit (112) is heated and inhaled by the user in the form of an aerosol.

[0152] Meanwhile, when the aerosol generating unit (112) is positioned closer to the user than the active ingredient generating unit (111), as shown in FIG. 8b, the user can inhale the aerosol generating unit with a moisturizing effect before the active ingredient, including nicotine and flavoring agent, during a puff. In this case, the user can improve the smoking experience according to the user's preference by inhaling the rich vapor before inhaling the bitter taste of nicotine and the aroma contained in the flavoring agent.

[0153] FIG. 9 is a drawing for explaining various configurations of an aerosol generating segment in a smoking article according to an embodiment of the present invention. FIG. 9 (a) is a cross-sectional view illustrating the active ingredient generating portion (111) of FIGS. 8a and 8b cut along the line AA', and (b) is a cross-sectional view illustrating the aerosol generating portion (112) of FIGS. 8a and 8b cut along the line BB'.

[0154] Referring to (a) of FIG. 9, the active ingredient generating portion (111) may include a plurality of sections (113, 114) separated in the thickness direction of the cross-section. The first section (113) and the second section (114) may extend in the longitudinal direction of the smoking article (10). As illustrated in FIG. 9, the first section (113) may be positioned more centrally than the second section (114), and the second section (114) may surround the side of the first section (113).

[0155] In some embodiments of the present invention, the distribution of the solids of nicotine, flavoring agent, and aerosol generating material included in the active ingredient generating unit (111) may vary depending on the location within the active ingredient generating unit (111). For example, the heating temperature within the active ingredient generating unit (111) may vary depending on the distance from the heat source that heats the active ingredient generating unit (111). When the aerosol generating segment (110) is heated from the outside by a heater disposed outside the receiving portion into which the smoking article (10) is inserted, the temperature of the first section (113) located relatively centrally in the cross-sectional direction of the active ingredient generating unit (111) may be formed lower than that of the second section (114). At this time, in order to increase the amount of aerosol emitted from the central portion, the first section (113) of the active ingredient generating unit (111) may have a solid distribution with an increased concentration than that of the second section (114).

[0156] Alternatively, if a heating rod is inserted into the aerosol generating segment (110) and heated, the temperature of the second section (114) may be formed lower than the temperature of the first section (113) located inside in the cross-sectional direction of the active ingredient generating section (111) in contrast to the above. Accordingly, in order to increase the amount of aerosol emitted from the outer portion, the second section (114) of the active ingredient generating section (111) may have a solid distribution with an increased concentration compared to the first section (113).

[0157] Referring to (b) of FIG. 9, the aerosol generating unit (112) may include a plurality of sections (115, 116) divided in the thickness direction of the cross-section. As illustrated in FIG. 9, the first section (115) may be located more centrally than the second section (116).

[0158] In some embodiments of the present invention, the distribution of the solid aerosol generating material in the aerosol generating unit (112) may vary depending on the location within the aerosol generating unit (112). Similar to the active ingredient generating unit (111), the first section (115) of the aerosol generating unit (112) may have a solid distribution with an increased concentration compared to the second section (116) in order to increase the amount of aerosol emitted from the center.

[0159] Alternatively, if a heating rod is inserted into the aerosol generating segment (110) and heated, the second section (116) of the aerosol generating portion (112) may have a solid distribution with an increased concentration than the first section (115).

[0160] FIGS. 10A to 10C are drawings for explaining the configuration of a wrapper that wraps a filter, a tube, and an aerosol generating segment in a smoking article according to an embodiment of the present invention.

[0161] Referring to FIG. 10A, a wrapper (140) may encapsulate each of the components by surrounding at least a portion of the side of the aerosol generating segment (110), the tube (120), and the filter (130), which includes the active ingredient generating portion (111) and the aerosol generating portion (112). The wrapper (140) may be, for example, a roll of paper, and in some embodiments, the wrapper (140) may include a porous roll of paper.

[0162] Meanwhile, as described above, since the nicotine, flavoring agent, and aerosol-generating material are formed in a solid form in the aerosol-generating segment (110), leakage to the outside of the aerosol-generating segment (110) can be prevented as much as possible, but since the wrapper (140) wraps the aerosol-generating segment (110), the nicotine, flavoring agent, and aerosol-generating material before being aerosolized by heating can be prevented from escaping to the outside of the aerosol-generating segment (110).

[0163] In addition, the wrapper (140) can prevent the aerosol generating segment (110), tube (120), and filter (130) from burning during the heating process by the aerosol generating device by including a non-combustible material.

[0164] Meanwhile, in some embodiments of the present invention, a flavorant may be applied to at least a portion of the wrapper (140). When the aerosol generating segment (110) of the smoking article (10) is heated, the wrapper (140) may also be heated. When the wrapper (140) is heated, the flavorant applied to the wrapper (140) may be mixed with the aerosol generated from the aerosol generating segment (110) and delivered to the user through inhalation.

[0165] Therefore, the user's smoking experience can be improved by obtaining an additional flavoring effect by the wrapper (140) in addition to the aerosol generating segment (110).

[0166] Referring to FIG. 10b, the wrapper (140) may include a first part (141) surrounding the active ingredient generating part (111), a second part (142) surrounding the aerosol generating part (112), a third part (143) surrounding the tube (120), and a fourth part (144) surrounding the filter (130). The first to fourth parts (141 to 144) may be separated from each other by physically separate wrappers, but the present invention is not limited thereto.

[0167] FIG. 10b illustrates a configuration in which a flavoring agent is applied to a wrapper surrounding a smoking article (10) previously illustrated in FIG. 1a, and specifically, (a) of FIG. 10b illustrates a configuration in which a flavoring agent is applied to a fourth part (144) surrounding a filter (130), (b) illustrates a configuration in which a flavoring agent is applied to a first part (141) surrounding an active ingredient generating part (111) and a fourth part (144) surrounding a filter (130), and (c) illustrates a configuration in which a flavoring agent is applied to the entire wrapper (140) except for a third part (143) surrounding a tube (120).

[0168] FIG. 10c illustrates a configuration in which a flavoring agent is applied to a wrapper surrounding a smoking article (11) illustrated in FIG. 8b, and specifically, (a) of FIG. 10c illustrates a configuration in which a flavoring agent is applied to a fourth portion (144) surrounding a filter (130), (b) illustrates a configuration in which a flavoring agent is applied to a second portion (142) surrounding an aerosol generating unit (112) and a fourth portion (144) surrounding a filter (130), and (c) illustrates a configuration in which a flavoring agent is applied to the entire wrapper (140) excluding a third portion (143) surrounding a tube (120).

[0169] In this way, the smoking article (10, 11) according to the embodiments of the present invention can provide a rich amount of smoke and improve the user's smoking experience by allowing the wrapper (140) to additionally supply flavoring.

[0170] Figures 11a to 11c are drawings for explaining the structure of a smoking article according to a modification of the second embodiment of the present invention.

[0171] Referring to FIG. 11a, a smoking article (20) according to the present invention includes an aerosol generating segment (210) including a nicotine and flavor generating portion (211) and an aerosol generating portion (212), a tube (220), and a filter (230), wherein a flavoring agent may be applied to the surface of an airflow passage (221) formed inside the tube (220). When the aerosol generated from the aerosol generating segment (210) is transmitted through the tube (220), it may be mixed with the flavoring agent applied to the airflow passage (221) to provide an additional flavor to the user. Through this, the user's smoking experience may be improved by obtaining the flavoring effect by the tube (220) in addition to the aerosol generating segment (210).

[0172] Meanwhile, the smoking article (20) illustrated in FIG. 11a has a configuration of an aerosol generating segment (210) in which an active ingredient generating portion (211) is positioned at the proximal portion of the user, and the smoking article (21) is illustrated to have a configuration of an aerosol generating segment (210) in which an aerosol generating portion (212) is positioned at the proximal portion of the user.

[0173] In some embodiments of the present invention, the smoking article (20) of FIG. 11a may also include a wrapper (240) that wraps the aerosol generating segment (210), the tube (220), and the filter (230) as in the previously described embodiment, and a flavoring agent may be applied to the wrapper (240) divided into first to fourth portions (241 to 244) corresponding to each segment.

[0174] FIG. 11b is a smoking article (20), in which (a) shows a configuration in which a flavoring agent is applied to a fourth portion (244) surrounding a filter (230), (b) shows a configuration in which a flavoring agent is applied to the first portion and the fourth portion (241, 244) surrounding an active ingredient generating portion (211) and a filter (230), and (c) shows a configuration in which a flavoring agent is applied to the entire wrapper (240) except for the third portion (243).

[0175] FIG. 11c is a smoking article (21), in which (a) shows a configuration in which a flavoring agent is applied to the fourth part (244) surrounding the filter (230), (b) shows a configuration in which a flavoring agent is applied to the second part and the fourth part (242, 244) surrounding the aerosol generating part (212) and the filter (230), and (c) shows a configuration in which a flavoring agent is applied to the entire wrapper (240) except for the third part (243).

[0176] In this way, the smoking article (20) according to embodiments of the present invention can improve the user's smoking experience by additionally supplying aerosol through the tube (220) and wrapper (240).

[0177] FIGS. 12a and 12b are drawings for explaining the structure of a smoking article according to another modification of the second embodiment of the present invention.

[0178] Referring to FIG. 12a, a smoking article (30) according to the present invention includes an aerosol generating segment (310), a tube (320), and a filter (330), wherein fragments (325) of a solid containing a flavoring agent may be applied to the inner wall of an airflow passage (321) formed inside the tube (320). The fragments (325) of the solid agent may be fixed to the inner wall of the airflow passage (321) by having a certain viscosity due to a thickener, and an aerosol may be generated from the fragments (325) of the solid agent applied to the surface of the airflow passage (321) by being heated by the aerosol generated from the aerosol generating segment (310).

[0179] This can improve the user's smoking experience by obtaining an additional flavoring effect through the tube (320) in addition to the aerosol generating segment (310).

[0180] Meanwhile, the smoking article (30) illustrated in FIG. 12a has a configuration of an aerosol generating segment (310) in which a nicotine and flavor generating portion (311) is positioned at the proximal portion of the user, and the smoking article (31) is illustrated to have a configuration of an aerosol generating segment (310) in which an aerosol generating portion (312) is positioned at the proximal portion of the user.

[0181] In some embodiments of the present invention, the smoking article (30) of FIG. 5A may also include a wrapper (340) that wraps the aerosol generating segment (310), the tube (320), and the filter (330) as in the previously described embodiment, and a solid form of a flavoring agent may be applied to the wrapper (340) divided into first to fourth portions (341 to 344) corresponding to each segment.

[0182] FIG. 12b is a smoking article (30), in which (a) shows a configuration in which a solid flavoring agent is applied to a fourth portion (344) surrounding a filter (330), (b) shows a configuration in which a solid flavoring agent is applied to the first portion and the fourth portion (341, 344) surrounding an active ingredient generating portion (311) and a filter (330), and (c) shows a configuration in which a solid flavoring agent is applied to the entire wrapper (340) except for the third portion (343).

[0183] FIG. 12c is a smoking article (31), in which (a) shows a configuration in which a solid flavoring agent is applied to the fourth part (344) surrounding the filter (330), (b) shows a configuration in which a solid flavoring agent is applied to the second part and the fourth part (342, 344) surrounding the aerosol generating part (312) and the filter (330), and (c) shows a configuration in which a solid flavoring agent is applied to the entire wrapper (340) except for the third part (343).

[0184] In this way, the smoking article (30) according to embodiments of the present invention can improve the user's smoking experience by additionally supplying aerosol from the tube (320) and the wrapper (340).

[0185] FIG. 13 is a drawing for explaining an aerosol generating device using a smoking article according to a second embodiment of the present invention.

[0186] Referring to FIG. 13, an aerosol generating device (1000) according to the present invention is a device that generates an aerosol by heating by inserting a smoking article (10) of the present invention, and may include a receiving portion (1010) into which a smoking article (10, 20, 30) is inserted, a heater (1020) that heats the smoking article (10), a power supply unit (1030) that supplies power to the heater (1020), and a control unit (1040) that controls the heater (1020) and the power supply unit (1030). Other heated smoking devices (1000) may further include a sensor that detects a user's puff or an output unit that informs the user of the current status.

[0187] The heater (1020) may be disposed at a position corresponding to the aerosol generating segment (110) of the smoking article (10) on the outside of the receiving portion (1020) and may include, but is not limited to, a coil that heats the smoking article (10) in a heating manner, and, unlike that illustrated in FIG. 13, may be configured to have the shape of a heating rod and be inserted into the aerosol generating segment (110) to directly transfer heat in a heating manner. In some embodiments of the present invention, the heater (1020) may heat the aerosol generating segment (110) to a temperature of 180° C. to 280° C.

[0188] Meanwhile, as illustrated in FIG. 13, the heater (1020) of the smoking article may include multiple heaters, such as a first heater (1021) positioned distally relative to the user and a second heater (1022) positioned proximally. The first heater (1021) and the second heater (1022) may be positioned to correspond to the position of the active ingredient generating unit (111) or the aerosol generating unit (112) when the smoking article (10) is inserted into the receiving port (1010).

[0189] When using the aerosol generating device (1000), the first heater (1021) and the second heater (1022) can heat the aerosol generating segment (110) at different heating temperatures, and in particular, the operations of the first heater (1021) and the second heater (1022) can be configured to have different heating temperatures or heating times for the active ingredient generating portion (111) or the aerosol generating portion (112).

[0190] Figure 14 is a flowchart for explaining a method for manufacturing a smoking article according to a second embodiment of the present invention.

[0191] Fig. 14 differs from Fig. 7 only in that it further includes a step (135) of forming a solid of an aerosol-generating substance using a thickener, but the description of other solid formation processes in Fig. 7 can be equally applied to the solid formation of this step (135).

[0192]

[0193] [Example 3]

[0194] The third embodiment is also described with reference to Fig. 8 in the same manner as the second embodiment.

[0195] The third embodiment differs from the second embodiment only in that the aerosol generating unit is formed in a gel state rather than a solid state.

[0196] Referring to FIGS. 8a and 8b, the aerosol generating segment (110) in the smoking article (10) of the present invention can be divided into an active ingredient generating portion (111) containing nicotine and a flavoring agent as a solid and an aerosol generating portion (112) containing an aerosol generating material as a gel.

[0197] FIG. 8b illustrates a smoking article (11) of an embodiment in which an aerosol generating unit (112) containing an aerosol generating material as a gel-like gel is positioned between an active ingredient generating unit (111) and a tube (120).

[0198] The aerosol generating unit (112) may include a gel in which an aerosol generating material is formed into a gel by a gel thickener. Such a gel may be formed by heating and dissolving the aerosol generating material in a solvent together with a gel thickener such as gelatin, applying the gel to a moisture absorbent, etc., cooling the gel to form a gel together with the moisture absorbent, and then being included in the aerosol generating unit (112). When the aerosol generating unit (112) is heated, the gel may be vaporized and inhaled by the user in the form of an aerosol.

[0199] In particular, the aerosol generating unit (112) may be a solid in a dispersed state, but may have the characteristics of a gel-like state, which is an intermediate state between a fluid and a perfect elastic body. The aerosol generating material may be formed into a gel-like state by a gel-like thickener, and may become the aerosol generating unit (112).

[0200] The above gel thickener may be at least one selected from the group consisting of agar extracted from the seaweed Agalactiae, carrageenans (kappa-carrageenan or iota-carrageenan) extracted from the seaweed red algae, plant-derived ...

[0201] When an aerosol-generating substance is formed into a gel by a gel-like thickener, a catalyst may be used as needed. For example, a gel-like gel can be obtained by dissolving the gel-like thickener and the aerosol-generating substance together in water at 85°C and then cooling. Adding casein at this time can also form a uniform gel.

[0202] In a smoking article (10) according to the second embodiment of the present invention, the target ingredient is formed into a solid or gel using a thickener or a gel thickener, thereby eliminating the concern about leakage and enabling the active ingredient to be delivered completely to the user.

[0203] In addition, a gel may be manufactured by forming an aerosol-generating material into a gel using a gel-like thickener, thereby allowing it to be included in the aerosol-generating unit (112).

[0204] In this way, the smoking article (10) according to the embodiment of the present invention can select various types of thickeners or gel thickeners depending on the types of flavoring, nicotine, and aerosol-generating material included in the aerosol-generating segment (110) and use them for each solidification or gelation.

[0205] Meanwhile, when the aerosol generating unit (112) is positioned closer to the user than the active ingredient generating unit (111), as shown in FIG. 8b, the user can inhale the aerosol generating unit with a moisturizing effect before the active ingredient, including nicotine and flavoring agent, during a puff.

[0208] [Example 4]

[0209] The fourth embodiment differs from the previous embodiments in that the aerosol generating segment comprises a nicotine generating portion comprising a first solid form of nicotine and an aerosol generating material, and a flavor generating portion comprising a flavorant and a second solid form of the aerosol generating material.

[0210] That is, although there are some differences only in the solid components that make up each component of the aerosol generating segment, since the method of manufacturing each solid is the same, the description of the second embodiment with reference to FIGS. 8 to 14 above can be applied identically by selectively changing only the components of each solid.

[0211] Referring to FIGS. 8a and 8b, a smoking article (10) according to a fourth embodiment of the present invention may include an aerosol generating segment (110), a tube (120), and a filter (130).

[0212] In the smoking article (10) according to the fourth embodiment, the aerosol generating segment (110) can be divided into a nicotine generating portion (111) containing nicotine as a solid and a flavor generating portion (112) containing a flavoring agent as a solid.

[0213] FIG. 8a illustrates a smoking article (10) of an embodiment in which a nicotine generating unit (111) containing nicotine as a solid is disposed between a flavor generating unit (112) and a tube (120), and FIG. 8b illustrates a smoking article (11) of an embodiment in which a flavor generating unit (112) containing a flavorant as a solid is disposed between a nicotine generating unit (111) and a tube (120).

[0214] The nicotine generating unit (111) may include a first solid body formed by a thickener of nicotine and an aerosol generating material. This first solid body may be included in the nicotine generating unit (111) in a state of being applied to an absorbent material or the like, and may be vaporized when the nicotine generating unit (111) is heated and inhaled by the user in the form of an aerosol.

[0215] The flavor generating unit (112) may include a second solid body formed by a flavoring agent and an aerosol generating material using a thickener. This second solid body may be included in the flavor generating unit (112) in a state of being applied to an absorbent material or the like, and may be vaporized when the flavor generating unit (112) is heated and inhaled by the user in the form of an aerosol.

[0216] Meanwhile, when the flavor generating unit (112) is positioned closer to the user than the nicotine generating unit (111), as shown in FIG. 8b, the user can inhale the vaporized flavoring agent before nicotine when taking a puff. In this case, the user can reduce the unpleasant sensation of smoking by inhaling the various flavors contained in the flavoring agent before experiencing the bitter taste of nicotine, thereby improving the smoking experience.

[0217] When FIG. 14 is applied to the manufacture of a smoking article according to the fourth embodiment of the present invention, the method for manufacturing a smoking article according to the fourth embodiment may include a step of forming a solid of nicotine using a thickener (S110), a step of forming a solid of a flavoring agent using a thickener (S120), a step of forming each of the nicotine solid and the flavoring solid into each of the solids using the thickener together with an aerosol-generating material (S130), a step of applying each of the formed solids to an absorbent to manufacture a nicotine generating portion and a flavor generating portion and manufacturing an aerosol-generating segment therefrom (S140), and a step of forming a smoking article by rolling the aerosol-generating segment into a wrapper together with a filter and a tube (S150).

[0218] Although the embodiments of the present invention have been described with reference to the attached drawings, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without altering the technical concept or essential features thereof. Therefore, the embodiments described above should be understood to be illustrative in all respects and not restrictive.
