Description

[Technical field]

[0001] The present disclosure relates to aerosol products and aerosol generating devices. [Background technology]

[0002] Generally, tobacco refers to a perennial plant of the Solanaceae family of dicotyledonous plants, but in recent times it has come to refer to a product manufactured for smoking, with tobacco leaves wrapped in cigarette paper and a filter on one side. There are thousands of varieties of such cigarettes available around the world, and they are sold in a variety of patterns and shapes.

[0003] Among these, in the case of combustible tobacco, which is smoked by lighting it, such as rolling cigarettes, cigars, and pipe tobacco, the smoke contains not only aerosols containing nicotine, but also large amounts of other components such as tar, nitroamines, hydrocarbons, and carbon monoxide.

[0004] As an alternative to the drawbacks of the combustion cigarette, a method of generating aerosol by heating an aerosol-generating substance in a cigarette, rather than by burning a cigarette, is widely used and in increasing demand, and as a result, research on heat-not-burn cigarettes or heat-not-burn aerosol generating devices is actively being conducted.

[0005] Specifically, aerosol generating devices have a similar form to conventional combustion cigarettes, and generate mainstream smoke containing aerosols by heating the aerosol-generating material in the heated cigarette using methods such as a heater or ultrasonic vibration. This has the advantage of minimizing the emission of components such as tar while satisfying the smoker's desire to smoke, and is creating a new market that replaces conventional combustion cigarettes.

[0006] Unlike conventional combustion cigarettes, the heated cigarettes used in such aerosol generating devices, i.e., aerosol products, are internally composed of various segments, which increases the manufacturing cost. Also, in the process of manufacturing the aerosol product, various segments are continuously supplied at high speed, which may cause frequent interruptions in production due to improper supply of segments during the production process. Summary of the Invention [Problem to be solved by the invention]

[0007] In order to solve the above problems, the objective of the present disclosure is to provide an aerosol product that can reduce production costs.

[0008] Another object of the present disclosure is to provide an aerosol product that can improve production efficiency. [Means for solving the problem]

[0009] According to one embodiment, an aerosol product may be provided that includes a tobacco medium section and a filter section coupled to one side of the tobacco medium section for cooling and filtering an aerosol transmitted from the tobacco medium section, the filter section including a first filter segment disposed away from the tobacco medium section for filtering the aerosol, an inner wrapper surrounding the first filter segment and extending toward the tobacco medium section, and a second filter segment surrounded by the tobacco medium section, the first filter segment, and the inner wrapper to form a space therein. Effect of the Invention

[0010] As discussed above, an aerosol product according to one aspect of the present disclosure can reduce production costs.

[0011] In addition, during the process of manufacturing an aerosol product, interruptions to production can be prevented, improving production efficiency.

[0012] In order that the contents of the present disclosure may be understood by those skilled in the art, a more detailed description may be given with reference to certain exemplary embodiment forms, some of which are illustrated in the accompanying drawings. [Brief description of the drawings]

[0035] 1 to 5, the aerosol product (100) according to the first embodiment of the present disclosure may include a tobacco medium part (110), a filter part (130), and an outer wrapper (170). In this case, the filter part (130) coupled to the tobacco medium part (110) may include a first filter segment (131), a second filter segment (135), and an inner wrapper (133), and the inner wrapper (133) may surround the first filter segment (131) performing a filtering function and extend toward the tobacco medium part (110) to form a second filter segment (135) in which a space is formed inside the inner wrapper (133).

[0036] That is, according to this embodiment, the filter portion (130) may be formed by integrally bonding a first filter segment (131) that performs a filtering function and a second filter segment (135) in which the space is formed and that performs a cooling function, via an inner wrapper (133), and such a filter portion (130) may be bonded to the end of the tobacco medium portion (110).

[0037] Here, a person having ordinary skill in the art related to this embodiment can understand that in addition to the components illustrated in Figures 1 to 5, other general-purpose components may be further included in the aerosol product (100).

[0038] The aerosol product (100) according to this embodiment can be inserted into an aerosol generating device (300, see FIG. 10) described below and heated. When the aerosol product (100) is heated, mainstream smoke can be delivered to a user. The mainstream smoke can be an airflow flowing from upstream to downstream inside the aerosol product (100). Here, upstream can refer to the tobacco medium part (110) side, and downstream can refer to the filter part (130) side. A user of the aerosol product (100) can inhale the mainstream smoke through the downstream end of the aerosol product (100).

[0039] The aerosol product 100 may have a cylindrical shape. In this case, the diameter of the aerosol product 100 may be about 4.7 mm to 9.9 mm. The tobacco medium portion 110 and the filter portion 130 may also have a cylindrical shape with a diameter of about 4.7 mm to 9.9 mm.

[0040] Additionally, the aerosol product 100 may have a length of 31 mm to 60 mm. The length of the tobacco medium portion 110 may be about 16 mm to 30 mm. The length of the filter portion 130 may be about 15 mm to 30 mm.

[0041] The values ​​for the shape, diameter, and length of the aerosol product 100 and components are shown as examples, but are not necessarily limited thereto, and the configuration and values ​​of the aerosol product 100 may be varied within the scope of those skilled in the art.

[0042] The tobacco medium portion 110, located upstream of the aerosol producing article 100, may contain a tobacco medium for generating an aerosol. The tobacco medium of the tobacco medium portion 110 contains nicotine, which allows mainstream smokers to experience the taste and aroma characteristic of a cigarette.

[0043] When the aerosol product (100) of this embodiment is heated by the aerosol generating device (300) described below, and the aerosol generated by the aerosol generating device (300) flows into the inside of the aerosol product (100), nicotine can be adsorbed on the surface of the aerosol and delivered to the user as the aerosol passes through the tobacco medium portion (110).

[0044] In this case, the nicotine contained in the tobacco medium may be one or more of free base nicotine and nicotine salt, and the nicotine may be naturally occurring nicotine or synthetic nicotine.

[0045] Nicotine salts can be formed by adding a suitable acid, including organic or inorganic acids, to nicotine. The acid for forming nicotine salts can be appropriately selected in consideration of the nicotine absorption rate in blood, the heating temperature of the heater, the flavor or taste, solubility, etc. For example, the acid for forming nicotine salts can be, but is not limited to, a single acid selected from the group consisting of benzoic acid, lactic acid, salicylic acid, lauric acid, sorbic acid, levulinic acid, pyruvic acid, formic acid, acetic acid, propionic acid, butyric acid, valeric acid, caproic acid, caprylic acid, capric acid, citric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, phenylacetic acid, tartaric acid, succinic acid, fumaric acid, gluconic acid, saccharic acid, malonic acid, or malic acid, or a mixture of two or more acids selected from the group.

[0046] Meanwhile, the tobacco medium of the tobacco medium portion (110) can be prepared in various forms. For example, the tobacco medium can be prepared in a sheet or a strand. The tobacco medium can also be prepared in a cut tobacco form in which the tobacco sheet is cut into small pieces. The tobacco medium can also be prepared in a granular form containing tobacco.

[0047] The tobacco medium portion 110 may have a cylindrical shape. However, the shape of the tobacco medium portion 110 is not necessarily limited to this, and may have a bar shape having a cross section of various shapes.

[0048] In this case, the tobacco medium portion (110) can be produced by folding a tobacco sheet so as to create wrinkles into a cylindrical shape, or by forming tobacco strands, cut tobacco, or tobacco granules into a cylindrical shape.

[0049] When the tobacco medium portion (110) is made of a plurality of tobacco strands obtained by shredding a tobacco sheet, the tobacco medium portion (110) may be formed by combining a plurality of tobacco strands in the same direction or randomly. Specifically, the tobacco medium portion (110) may be formed by combining a plurality of tobacco strands to form a plurality of longitudinal channels through which the aerosol can pass. In this case, the longitudinal channels may be uniform or non-uniform depending on the size and arrangement of the tobacco strands.

[0050] The tobacco medium portion 110 may further include an aerosol generating material to increase the amount of atomization, for example, the aerosol generating material may include, but is not limited to, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol.

[0051] The tobacco medium portion 110 may further include a flavoring material to add flavor to the aerosol. For example, the tobacco medium portion 110 may contain other additives such as flavoring agents, humectants, and / or organic acids. In addition, a flavoring liquid such as menthol or a humectant may be added to the tobacco medium portion 110 by being sprayed.

[0052] In this case, the flavoring agent may include licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, salvia, spearmint, ginger, coriander, or coffee, etc. Also, the humectant may include glycerin or propylene glycol, etc.

[0053] The tobacco medium portion (110) may be surrounded by a thermally conductive material. The thermally conductive material may uniformly distribute the heat transferred to the tobacco medium portion (110) to improve the thermal conductivity of the heat transferred to the tobacco medium portion (110), thereby improving the taste of the tobacco. The thermally conductive material may be a metal foil, for example, the thermally conductive material may be aluminum. However, the thermally conductive material is not necessarily limited thereto, and various metal foils may be used as the thermally conductive material.

[0054] Meanwhile, in this embodiment, the tobacco medium portion (110) may be composed of at least one segment. For example, the tobacco medium portion (110) may be composed of one tobacco segment, two tobacco segments, or three tobacco segments. Specifically, the tobacco medium portion (110) according to this embodiment shown in FIG. 5 may be composed of one tobacco segment. Also, as shown in FIG. 6 and FIG. 7, the tobacco medium portion (110) may be composed of two tobacco segments. Also, as shown in FIG. 8, the tobacco medium portion (110) may be composed of three tobacco segments.

[0055] 5, the tobacco medium portion (110) of this embodiment may be composed of one tobacco segment. The tobacco segment of the tobacco medium portion (110) may be filled with a tobacco medium. That is, in this embodiment, the tobacco medium portion (110) may be composed of one tobacco segment filled with a tobacco medium.

[0056] In this case, the tobacco segment may be prepared by folding a tobacco sheet into a cylindrical shape as described above, or by forming a tobacco strand, cut tobacco, or tobacco granules into a cylindrical shape. The tobacco segment may further include an aerosol-generating material and / or a flavoring material capable of increasing the amount of atomization.

[0057] Also, a heating section (370, see FIG. 10 ) of the aerosol generating device (300) for heating the aerosol product (100) may be inserted into the tobacco segment of the tobacco medium section (110). In FIG. 10 , the heating section (370) is illustrated as being disposed around the aerosol product (100), but this is not limited thereto, and the heating section may be inserted inside the tobacco medium section (110) to heat the tobacco medium section (110).

[0058] The tobacco medium portion (110) may further include a configuration for identifying the aerosol product (100). The aerosol product (100) may exhibit various flavors and aromas, and may include a configuration (not shown) for identifying such various types of aerosol product (100) from one another. For example, the tobacco medium portion (110) may include a metal foil that changes the inductance of an aerosol product recognition coil included in the aerosol generating device (300). In this case, the metal foil may be disposed on the outer circumferential surface of the tobacco medium portion (110).

[0059] On the other hand, in the variation illustrated in Figures 6 and 7, the tobacco medium portion (110) may be comprised of two tobacco segments, one of which may include the tobacco medium and the other of which may not include the tobacco medium.

[0060] Referring to Figure 6, the tobacco medium section (110) may include a first tobacco segment (111) and a second tobacco segment (119). The first tobacco segment (111) is a tobacco segment filled with a tobacco medium and may be the same as the tobacco segment of the tobacco medium section (110) of Figure 5 described above.

[0061] The second tobacco segment (119) is located at the upstream end of the aerosol product (100) and can prevent the first tobacco segment (111) containing the tobacco medium from escaping to the outside. That is, the tobacco medium portion (110) of this modified example can be arranged in the order of the second tobacco segment (119) and the first tobacco segment (111) from the upstream side.

[0062] The second tobacco segment (119) can prevent impurities from entering the first tobacco segment (111) from the outside and can prevent aerosol liquefied during smoking from flowing into the aerosol generating device (300, see Figure 10).

[0063] Additionally, when the aerosol product (100) is inserted into the aerosol generation device (300), the second tobacco segment (119) can support the aerosol product (100) so that the aerosol product (100) is fixed to the aerosol generation device (300).

[0064] The second segment (119) may be a cellulose acetate filter. For example, the second segment (119) may be made of cellulose acetate tow with a plasticizer such as triacetin added thereto. The cellulose acetate tow may also include an aerosol-generating material.

[0065] The aerosol generating material contained in the second segment (119) may exclude nicotine. For example, the second segment (119) may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. However, the aerosol generating material contained in the second segment (119) is not necessarily limited thereto. For example, the second segment (119) may include a material in which glycerin and propylene glycol are mixed in a ratio of approximately 8:2. However, the mixture ratio is not limited to the above-mentioned ratio.

[0066] In addition, the second segment (119) may contain other additives such as flavorings, humectants, and / or organic acids. However, the material and type of the second segment (119) are not necessarily limited thereto and may be changed within the scope of what can be adopted by those skilled in the art.

[0067] Meanwhile, the second segment (119) may have a through hole through which the aerosol flows from the outside to form mainstream smoke inside the aerosol production product (100). The through hole formed in the second segment (119) may have a circular or Y-shaped cross section. However, the cross-sectional shape of the through hole is not necessarily limited thereto, and may have various cross-sectional shapes.

[0068] On the other hand, if the second segment (119) comprises a crimped sheet impregnated with the aerosol generating material, then the second segment (119) may not have any holes formed therein.

[0069] In this case, when a portion of the aerosol product (100) is inserted into the aerosol generating device (300), the aerosol generated in the aerosol generating device (300) flows into the aerosol product (100) through the second tobacco segment (119), and the aerosol forms mainstream smoke in the aerosol product (100) and can be delivered to the user. Also, the aerosol generated in the second tobacco segment (119) containing the aerosol generating material can form mainstream smoke and be delivered to the user.

[0070] The second tobacco segment (119) may further include a configuration for identifying the aerosol product (100). The aerosol product (100) may exhibit various flavors, aromas, etc., and may include a configuration for identifying various types of aerosol product (100) from one another. For example, the second tobacco segment (119) may include a metal foil that changes the inductance of an aerosol product recognition coil included in the aerosol generating device (300). However, this is not necessarily limited thereto, and the configuration for identifying the aerosol product (100) may be included in the first tobacco segment (111) in addition to the second tobacco segment (119).

[0071] Referring to FIG. 7, the tobacco medium portion (110) can include a first tobacco segment (111) and a second tobacco segment (117).

[0072] The first tobacco segment (111) is located at the upstream end, and the first tobacco segment (111) is a segment filled with tobacco medium and may be made of the same material as the first tobacco segment (111) of Figure 6 described above.

[0073] The second tobacco segment (117) can prevent the tobacco medium of the first tobacco segment (111) from escaping to the filter section (130) described below. For example, when a heating section for heating the aerosol product (100) is inserted into the first tobacco segment (111), the tobacco medium in the first tobacco segment (111) can detach and move toward the filter section (130). By disposing the second tobacco segment (117) between the first tobacco segment (111) and the filter section (130), the tobacco medium in the first tobacco segment (111) can be prevented from escaping to the filter section (130).

[0074] The second tobacco segment (117) may be made of the same materials as the second tobacco segment (119) of FIG. 6 described above.

[0075] Also, the second tobacco segment (117) may have a through hole formed in the first tobacco segment (111) or through the first tobacco segment (111) for allowing the aerosol to flow in. The through hole formed in the second tobacco segment (117) may have a circular or Y-shaped cross section. However, the cross-sectional shape of the through hole is not necessarily limited thereto and may have various cross-sectional shapes.

[0076] In this manner, the first tobacco segment (111) and the second tobacco segment (117) of the tobacco medium part (110) may be made of the same material as the first tobacco segment (111) and the second tobacco segment (119) of the tobacco medium part (110) of Fig. 6 described above. However, the first tobacco segment (111) and the second tobacco segment (117) of the tobacco medium part (110) may be arranged in an order different from that of the first tobacco segment (111) and the second tobacco segment (119) of Fig. 6. That is, the tobacco medium part (110) of this modification may be arranged in the order of the first tobacco segment (111) and the second tobacco segment (117) from the upstream side.

[0077] On the other hand, in the variation illustrated in Figure 8, the tobacco medium portion (110) may be comprised of three tobacco segments, at least one of which may include a tobacco medium.

[0078] 8, the tobacco medium portion (110) may include a first tobacco segment (111), a second tobacco segment (113), and a third tobacco segment (115). In this modification, the first tobacco segment (111) including the tobacco medium may be disposed in the center, and the second tobacco segment (113), the first tobacco segment (111), and the third tobacco segment (115) may be disposed in this order from the upstream side.

[0079] The first tobacco segment (111) is located in the middle of the three tobacco segments of the tobacco medium portion (110). The first tobacco segment (111) is a segment filled with tobacco medium and may be made of the same material as the first tobacco segment (111) of FIG. 6 described above.

[0080] The second tobacco segment (113) and the third tobacco segment (115) are arranged on either side of the first tobacco segment (111), and the second tobacco segment (113) and the third tobacco segment (115) may be made of the same material as the second tobacco segment (119) of Figure 6 described above.

[0081] The second tobacco segment (113) can prevent impurities from entering the first tobacco segment (111) from the outside and can prevent aerosol liquefied during smoking from flowing into the aerosol generating device (300). In addition, the second tobacco segment (113) can have the same structure, function and material as the second segment (119) of FIG. 6 described above.

[0082] The third tobacco segment (115) can prevent the tobacco medium of the first tobacco segment (111) from escaping into the filter portion (130). In addition, the third tobacco segment (115) can have the same structure, function and material as the second tobacco segment (117) of FIG. 7 described above.

[0083] In this manner, in this modified example, a tobacco medium portion (110) can be formed by arranging a second tobacco segment (113) and a third tobacco segment (115) on either side of a first tobacco segment (111) containing a tobacco medium.

[0084] 1 to 5, in this embodiment, a filter portion 130 may be coupled to the downstream end of the tobacco medium portion 110. The filter portion 130 may cool or filter at least one of the substances contained in mainstream smoke.

[0085] The filter portion 130 may have the same shape as the tobacco medium portion 110, and may have the same cylindrical shape as the tobacco medium portion 110. The filter portion 130 may have the same outer diameter as the tobacco medium portion 110. However, the shape and outer diameter of the filter portion 130 are not necessarily limited thereto, and may have various shapes and outer diameters corresponding to the shape and outer diameter of the tobacco medium portion 110.

[0086] The filter part (130) may include a first filter segment (131), a second filter segment (135), and an inner wrapper (133). In the filter part (130), the inner wrapper (133) may surround the first filter segment (131) performing a filtering function and extend toward the tobacco medium part (110) to form a second filter segment (135) having a space formed inside the inner wrapper (133). In this case, the second filter segment (135) and the first filter segment (131) may be disposed adjacent to the tobacco medium part (110) in that order.

[0087] According to this embodiment, the filter unit (130) may be formed by integrally connecting a first filter segment (131) performing a filtering function and a second filter segment (135) having the space and performing a cooling function through an inner wrapper (133), and the filter unit (130) may be connected to an end of the tobacco medium unit (110). That is, in this embodiment, the first filter segment (131), the second filter segment (135), and the inner wrapper (133) constituting the filter unit (130) may be formed as one body, and the filter unit (130) may be connected to the tobacco medium unit (110).

[0088] The first filter segment (131) may be a cellulose acetate filter, and may be prepared by adding a plasticizer such as triacetin to cellulose acetate tow. However, the material and type of the first filter segment (131) are not necessarily limited thereto, and may be changed within the range that can be adopted by those skilled in the art.

[0089] The first filter segment (131) may be cylindrical in shape so as to correspond to the shape of the filter portion (130). However, the shape of the first filter segment (131) is not necessarily limited thereto, and like the filter portion (130), the first filter segment (131) may have various shapes so as to correspond to the shape of the tobacco medium portion (110).

[0090] The first filter segment (131) may have a length that is half or more of the length of the filter portion (130). Thus, the first filter segment (131) may be the same length as or greater than the second filter segment (135).

[0091] The first filter segment (131) may be fabricated to generate a flavor. For example, a flavoring liquid may be sprayed onto the first filter segment (131), or a separate fiber onto which the flavoring liquid is applied may be included inside the first filter segment (131).

[0092] Alternatively, the first filter segment (131) may include at least one capsule (not shown). The capsule may generate flavor or generate aerosol. For example, the capsule may have a structure in which a liquid containing a flavoring agent is enveloped in a membrane. In this case, the capsule may have a spherical or cylindrical shape, but the shape of the capsule is not necessarily limited thereto.

[0093] The filter portion (130) according to this embodiment may be wrapped by an inner wrapper (133). The inner wrapper (133) may surround the first filter segment (131) spaced apart from the tobacco medium portion (110) and extend toward the tobacco medium portion (110). In this case, a space corresponding to the second filter segment (135) may be formed inside the inner wrapper (133).

[0094] The inner wrapper (133) can surround at least a portion of the outer periphery of the first filter segment (131). Preferably, the inner wrapper (133) can surround the entire outer periphery of the first filter segment (131).

[0095] That is, the second filter segment (135) and the first filter segment (131) are disposed adjacent to the tobacco medium portion (110) inside the inner wrapper (133) in this order, so that the first filter segment (131), the second filter segment (135), and the inner wrapper (133) are integrally bonded to form a single filter portion (130). In this manner, the filter portion (130) integrally bonded by the inner wrapper (133) can be bonded to the tobacco medium portion (110) as a single body. Here, "a single body" may mean that the first filter segment (131) and the inner wrapper (133) are bonded with an adhesive or the like to be maintained as a single structure.

[0096] At this time, the inner wrapper 133 may have at least one opening (not shown) formed therein to allow outside air to flow in and the inside air to flow out.

[0097] The inner wrapper (133) may include a paper having a strength capable of maintaining the shape of the second filter segment (135) having a circular cross section. For example, the inner wrapper (133) may be a laminated paper made up of multiple papers. For example, the inner wrapper (133) may be a laminated paper made up of an outer paper, a middle paper, and an inner paper, but is not necessarily limited to this, and may be a single paper. On the other hand, when the inner wrapper (133) is made up of multiple papers, the inner surface of the inner paper may be coated with a predetermined substance, for example, polylactic acid.

[0098] When the inner wrapper (133) is paper, the total thickness of the inner wrapper (133) may be within the range of about 100 μm to 350 μm. Preferably, the total thickness of the inner wrapper (133) may be, but is not limited to, about 110 μm to 180 μm.

[0099] Also, if the inner wrapper (133) is paper, the overall basis weight of the inner wrapper (133) is about 80 g / m 2 ~150g / m 2 Preferably, the overall basis weight of the inner wrapper (133) is about 240 g / m 2 It can be, but is not limited to.

[0100] The outer diameter of the inner wrapper (133) may be the same as the outer diameter of the tobacco medium portion (110), such that the filter portion (130) and the tobacco medium portion (110) that are surrounded by the outer wrapper (170) may have a uniform outer diameter.

[0101] Meanwhile, at least a portion of the inner wrapper (133) may be a porous paper. The porous paper may have a high air permeability or permeability. The high permeability of the porous paper may facilitate the passage of air through the inner wrapper (133) including the porous paper.

[0102] The second filter segment (135) may be defined as a space formed by the inner wrapper (133). Of the first filter segment (131) and the second filter segment (135) that constitute the filter portion (130), the second filter segment (135) may be located adjacent to the tobacco medium portion (110). In other words, the second filter segment (135) may be located between the tobacco medium portion (110) and the first filter segment (131).

[0103] The second filter segment (135) can cool the hot aerosol formed in the tobacco medium portion (110) or passing through the tobacco medium portion (110). The hot aerosol is cooled as it moves through the second filter segment (135), and the cooled aerosol can be transmitted to the user through the first filter segment (131). This makes it possible to prevent the hot aerosol from being directly transmitted to the user.

[0104] Meanwhile, the aerosol product (100) according to this embodiment may be packaged with an outer wrapper (170). The outer wrapper (170) may surround the tobacco medium portion (110) and the filter portion (130). When the outer wrapper (170) surrounds the tobacco medium portion (110) and the filter portion (130) in this manner, the aerosol product (100) may maintain its inherent cylindrical rod shape.

[0105] At least one opening (not shown) may be formed in the outer wrapper (170) to allow outside air to flow into or inside air to flow out of the aerosol-producing article (100). The opening may be formed at a corresponding position in the tobacco medium portion (110), at a corresponding position in the inner wrapper (133), or at a corresponding position in the first filter segment (131).

[0106] The outer wrapper (170) may be a paper having physical properties such as tensile strength, water resistance, and smoothness that are greater than those of ordinary paper, thereby increasing the strength of the aerosol product (100) packaged in the outer wrapper (170), increasing resistance to external liquids that may come into contact with the aerosol product (100) due to the high water resistance, and making it easier to print on the outer wrapper (170) due to the high smoothness.

[0107] The basis weight of the outer wrapper (170) is about 40 g / m 2 More than 70g / m 2 or less, preferably about 45 g / m 2 2 or more 55g / m 2 The thickness of the wrapper (170) may be about 50 μm to 70 μm, and may be about 60 μm to 70 μm, where the thickness of the outer wrapper (170) may be less than the thickness of the inner wrapper (133).

[0108] A specific material may be added to the outer wrapper 170. An example of the specific material may be silicon, which has properties such as heat resistance with little change due to temperature, oxidation resistance, resistance to various chemicals, water repellency, and electrical insulation. However, the specific material is not limited to these, and any material having the above-mentioned properties may be applied or coated on the outer wrapper 170 without any restrictions.

[0109] Since the outer wrapper 170 forms the outermost surface of the aerosol product article 100, the shape of the aerosol product article 100 may be changed according to the shape of the outer wrapper 170. For example, the outer wrapper 170 may be printed with text, patterns, symbols, images, etc., and the text, patterns, symbols, images, etc. printed on the outer wrapper 170 may be changed, so that the aerosol product article 100 may provide different visual information.

[0110] Conventional aerosol products are manufactured by bonding a tobacco medium section, a separate tubular cooling section, and a filter section together, and then wrapping the entire assembly in an outer wrapper. However, in this embodiment, a space corresponding to the conventional separate cooling section can be formed by the inner wrapper (133) without the need for a separate cooling section. Thus, according to this embodiment, the manufacturing cost can be reduced by not using a separate cooling section.

[0111] In addition, in the process of manufacturing an aerosol product, a tobacco medium section, a tubular cooling section, and a filter section are sequentially placed at high speed onto the unfolded outer wrapper, and then the outer wrapper wraps the tobacco medium section, the cooling section, and the filter section. However, if at least one of the tobacco medium section, the cooling section, and the filter section placed on the outer wrapper is not placed in a fixed position, the manufacturing process of the aerosol product is interrupted.

[0112] According to this embodiment, a separate tubular cooling section is not inserted, but only the tobacco medium section (110) and the filter section (130). That is, unlike the conventional method which requires the insertion of three parts, i.e., the tobacco medium section, the cooling section, and the filter section, this embodiment allows the insertion of only two parts, i.e., the tobacco medium section (110) and the filter section (130), during the manufacturing process.

[0113] Therefore, in this embodiment, unlike the conventional method, the number of parts required to produce the aerosol product 100 is reduced. As a separate tube-shaped cooling unit is not required to produce the aerosol product, factors that may interrupt production during the production process, such as the cooling unit not being placed in the correct position, are reduced, thereby improving the production efficiency of the aerosol product.

[0114] The following describes an aerosol product according to a second embodiment of the present disclosure.

[0115] FIG. 9 is a cross-sectional view of an aerosol product according to a second embodiment of the present disclosure.

[0116] Referring to FIG. 9, the aerosol product according to the second embodiment has the same structure as the aerosol product according to the first embodiment (100) except for the recessed portion (190), and therefore a duplicated description of the same components will be omitted.

[0117] 9, in this embodiment, a recess (190) may be formed downstream of the filter unit (130). That is, the recess (190) may be formed at an end of the filter unit (130).

[0118] The recessed portion 190 has a structure in which the outer wrapper 170 and the inner wrapper 133 surrounding the first filter segment 131 extend further downstream than the first filter segment 131. That is, in this embodiment, the outer wrapper 170 and the inner wrapper 133 extend further outside the first filter segment 131 than in the aerosol product 100 of the first embodiment described above.

[0119] Due to the shapes of the outer wrapper (170) and the inner wrapper (133), the filter portion (130) may have a recessed rod shape.

[0120] The recessed portion 190 can prevent traces of nicotine generated on the downstream end of the filter portion 130 from being easily exposed to the outside. Therefore, traces of nicotine generated on the filter portion 130 of the aerosol product 100 during smoking or after smoking is completed are not exposed to the outside, so that the aesthetic appearance may not be impaired.

[0121] Hereinafter, an aerosol generating device into which an aerosol product according to a first embodiment of the present disclosure is inserted will be described.

[0122] FIG. 10 is a schematic diagram of an aerosol generating device into which an aerosol product according to the first embodiment of the present disclosure is inserted.

[0123] 10, the aerosol generating device 300 according to this embodiment may include a heating unit 370, a power supply unit 330, a control unit 310, and an aerosol generating unit 350. In addition to the components shown in FIG. 10, it may be understood by a person skilled in the art that the aerosol generating device 300 may further include other general-purpose components.

[0124] On the other hand, although the power supply unit (330), the control unit (310), and the aerosol generating unit (350) are illustrated as being arranged in a line in Fig. 10, the arrangement of the power supply unit (330), the control unit (310), and the aerosol generating unit (350) may be changed as necessary. Also, although the aerosol generating unit (350) is illustrated as being included in Fig. 10, the aerosol generating unit (350) may be omitted, and the aerosol product (100) may be operated only by being heated by the heating unit (370).

[0125] An aerosol production product (100) may be inserted into the aerosol generation device (300). The aerosol production product (100) may be inserted and fixed in the aerosol generation device (300) by a fixing means. In this embodiment, the tobacco medium part (110) of the aerosol production product (100) may correspond to the fixing means. However, in addition to the tobacco medium part (110), other fixing means may be added.

[0126] The heating unit 370 can heat the aerosol product 100. The heating unit 370 is heated by the power supplied from the power supply unit 330, and can thereby transfer heat to the aerosol product 100.

[0127] The heating element (370) can be an electrically resistive heater. The heating element (370) can include an electrically conductive track, and the heating element (370) can heat the aerosol product (100) by applying an electric current to the electrically conductive track via a power source provided by the power source unit (330).

[0128] As another example, the heating unit 370 can be an inductive heater. The heating unit 370 can include an electrically conductive coil for inductively heating the aerosol product article 100, and the aerosol product article 100 can include a susceptor that can be heated by the inductive heater.

[0129] The heating unit (370) in Fig. 10 is shown to be disposed externally to the aerosol product (100), but is not necessarily limited thereto. The heating unit (370) may include at least one of a tubular heating element, a plate heating element, a needle heating element, or a rod heating element, and may heat the interior or exterior of the aerosol product (100) depending on the shape of the at least one heating element included in the heating unit (370), or may heat both the interior and the exterior.

[0130] The power supply unit (330) supplies power used in the aerosol generating device (300). For example, the power supply unit (330) can supply power to heat the heating unit (370) and can supply power necessary for the control unit (310) to operate. The power supply unit (330) can also supply power necessary for the display, sensor, motor, etc. of the aerosol generating device (300) to operate.

[0131] The control unit (310) controls the overall operation of the aerosol generation device (300). Specifically, the control unit (310) controls the operation of the power supply unit (330) and other components included in the aerosol generation unit (350). The control unit (310) can also check the state of each component of the aerosol generation device (300) to determine whether the aerosol generation device (300) is in an operable state.

[0132] The aerosol generating unit (350) can heat the liquid composition to generate an aerosol, and the generated aerosol can be transmitted to a user through the aerosol product (100). In other words, the aerosol generated by the aerosol generating unit (350) can flow into the tobacco medium portion (110) of the aerosol product (100).

[0133] The aerosol generation unit (350) may include, but is not limited to, a liquid reservoir, a liquid transfer means, and a heating element. For example, the liquid reservoir, the liquid transfer means, and the heating element may be included in the aerosol generation device (300) as separate modules.

[0134] The liquid reservoir can store a liquid composition. For example, the liquid composition can be a liquid containing tobacco-containing substances including volatile tobacco aroma components, or a liquid containing non-tobacco substances. The liquid reservoir can be made removable or integral with the aerosol generating device (300).

[0135] When the aerosol generating unit (350) according to an embodiment of the present disclosure contains a liquid containing a non-tobacco substance, the liquid composition stored in the liquid storage unit included in the aerosol generating unit (350) may not contain nicotine, and the aerosol generated from the aerosol generating unit (350) may flow into the tobacco medium unit (110) without containing nicotine. In this case, the aerosol not containing nicotine passes through the tobacco medium unit (110) and adsorbs nicotine, and the aerosol that has passed through the tobacco medium unit (110) contains nicotine.

[0136] The liquid composition contained in the aerosol generating unit (350) may include water, a solvent, ethanol, a plant extract, a flavor, a flavoring agent, or a vitamin mixture. The flavoring agent may include, but is not limited to, menthol, peppermint, spearmint oil, various fruit fragrance ingredients, and the like. The flavoring agent may include ingredients that can provide various flavors or tastes to the user. The vitamin mixture may include, but is not limited to, at least one of vitamin A, vitamin B, vitamin C, and vitamin E. The liquid composition may also include an aerosol forming agent, such as glycerin and propylene glycol.

[0137] The following describes a method for producing the aerosol product (100) according to the first embodiment of the present disclosure.

[0138] 11 to 14 are diagrams showing a process for producing an aerosol product according to the first embodiment of the present disclosure.

[0139] Referring to Figures 11 to 14, the manufacturing method of the aerosol product of this embodiment may include a step of continuously feeding components (see Figure 11), a step of packaging with an outer wrapper (see Figure 12), a step of cutting (see Figure 13), and a step of separating into unit aerosol product (see Figure 14).

[0140] In the method for manufacturing the aerosol product according to this embodiment, a tobacco medium rod (110L) and a filter rod (130L) are continuously fed onto a spread continuous outer wrapper (170L) and cut to a certain size to produce a unit aerosol product (100).

[0141] 11, the tobacco medium rod (110L) and the filter rod (130L) are alternately and continuously fed onto the continuous wrapper (170L) which is continuously fed in. At this time, the tobacco medium rod (110L) and the filter rod (130L) are positioned so as to be in close contact with each other.

[0142] In this case, the tobacco medium rod (110L) may have a length equivalent to twice the length of the tobacco medium portion (110) described above. Similarly, the filter rod (130L) may have a length equivalent to twice the length of the filter portion (130) described above.

[0143] In the cutting process, if the tobacco medium rod (110L) is cut in half, it can be separated into two tobacco medium portions (110). Also, in the cutting process, if the filter portion (130) is cut in half, it can be separated into two filter portions (130).

[0144] Referring to Fig. 12, the tobacco medium rod (110L) and the filter rod (130L) that are in close contact with each other can be surrounded by a continuous wrapper (170L). An adhesive can be applied to the inside of the continuous outer wrapper (170L) or to the outer circumferential surfaces of the tobacco medium rod (110L) and the filter rod (130L), and the tobacco medium rod (110L) and the filter rod (130L) can be wrapped in the continuous outer wrapper (170L). As described above, the tobacco medium rod (110L) located inside the continuous outer wrapper (170L) can have twice the length of the tobacco medium portion (110), and the filter rod (130L) can have twice the length of the filter portion (130).

[0145] Referring to Figure 13, the tobacco medium rod (110L) and the filter rod (130L) wrapped in the continuous outer wrapper (170L) can be cut. The tobacco medium rod (110L) and the filter rod (130L) continuously fed into the continuous outer wrapper (170L) can be cut into two equal parts.

[0146] More specifically, as shown in Figure 13, each tobacco medium rod (110L) can be cut in half and each filter rod (130L) can be cut in half, such that one tobacco medium rod (110L) can be separated into two tobacco medium portions (110) and one filter rod (130L) can be separated into two filter portions (130).

[0147] 14, the tobacco medium rod (110L) and the filter rod (130L) can be cut and separated into unit aerosol products (100A, 100B, 100C, 100D). Here, the unit aerosol products (100A, 100B, 100C, 100D) may correspond to the aerosol product (100) according to the above-mentioned embodiment. Thus, in this embodiment, the tobacco medium rod (110L) and the filter rod (130L) provided on the continuous outer wrapper (170L) can be cut into two equal parts to manufacture a plurality of unit aerosol products (100A, 100B, 100C, 100D).

[0148] Although one embodiment of the present disclosure has been described above, a person having ordinary knowledge in the technical field may modify and change the present disclosure in various ways, such as by adding, changing, deleting or adding components, without departing from the concept of the present disclosure described in the claims, and this may also be considered to be within the scope of the rights of the present disclosure.
