Therefore, the terms used in the present invention should be defined not merely by their names, but based on their meanings and the overall content of the invention.

[0026] When a part of a specification is described as "including" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Furthermore, terms such as "~part" or "~module" as used in the specification refer to a unit that processes at least one function or operation, and this may be implemented in hardware or software, or as a combination of hardware and software.

[0027] As used herein, when an expression such as "at least one" precedes an arranged component, it modifies the entire set of components rather than each individual component. For example, the expression "at least one of a, b, and c" should be interpreted as including a, b, and c, or a and b, a and c, b and c, or a, b, and c.

[0028] In the following embodiments, "aerosol generating article" may refer to an article that contains a medium, through which an aerosol passes and the medium is transferred. Representative examples of aerosol generating articles may include cigarettes, but the scope of the present disclosure is not limited thereto.

[0029] In the following embodiments, "upstream" or "upstream direction" may mean a direction away from the user's (smoker's) bend, and "downstream" or "downstream direction" may mean a direction closer to the user's bend. The terms upstream and downstream may be used to describe the relative positions of the elements constituting the aerosol-generating article.

[0030] In the following embodiments, "puff" refers to the user's inhalation, and inhalation refers to a situation in which something is drawn into the user's oral cavity, nasal cavity, or lungs through the user's mouth or nose.

[0031] In one embodiment, the aerosol generating device may be a device that generates an aerosol by electrically heating an aerosol generating article contained in an internal space.

[0032] The aerosol generating device may include a heater. In one embodiment, the heater may be an electric resistive heater. For example, the heater may include an electric conductive track, and the heater may be heated when current flows through the electric conductive track.

[0033] The heater may include a tubular heating element, a plate heating element, a needle heating element, or a rod heating element, and may heat the inside or outside of an aerosol-generating article depending on the shape of the heating element.

[0034] The aerosol-generating article may include a tobacco rod and a filter rod. The tobacco rod may be made of a sheet, a strand, or the tobacco sheet may be made of finely shredded tobacco. Additionally, the tobacco rod may be surrounded by a heat-conducting material. For example, the heat-conducting material may be a metal foil, such as aluminum foil, but is not limited thereto.

[0035] The filter rod may be a cellulose acetate filter. The filter rod may be composed of at least one segment. For example, the filter rod may include a first segment that cools the aerosol and a second segment that filters a certain component contained within the aerosol.

[0036] In another embodiment, the aerosol generating device may be a device that generates an aerosol using a cartridge that holds an aerosol generating substance.

[0037] An aerosol generating device may include a cartridge holding an aerosol generating substance and a main body supporting the cartridge. The cartridge may be detachably coupled to the main body, but is not limited thereto. The cartridge may be formed integrally with or assembled with the main body, or it may be fixed so as not to be detached by a user. The cartridge may be mounted on the main body while containing an aerosol generating substance inside. However, it is not limited thereto, and the aerosol generating substance may be injected into the cartridge while the cartridge is coupled to the main body.

[0038] The cartridge may contain an aerosol-generating material having any one of various states, such as a liquid state, a solid state, a gaseous state, or a gel state. The aerosol-generating material may include a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing material containing a volatile tobacco flavor component, or a liquid containing a non-tobacco material.

[0039] The cartridge can perform the function of generating an aerosol by operating via an electrical signal or wireless signal transmitted from the main body, thereby converting the phase of the aerosol generating material inside the cartridge into a gaseous phase. The aerosol may refer to a gas in a state in which vaporized particles generated from the aerosol generating material and air are mixed.

[0040] In another embodiment, the aerosol generating device can generate an aerosol by heating a liquid composition, and the generated aerosol can be delivered to the user by passing through a cigarette. That is, the aerosol generated from the liquid composition can move along the airflow passage of the aerosol generating device, and the airflow passage can be configured so that the aerosol can be delivered to the user by passing through the cigarette.

[0041] In another embodiment, the aerosol generating device may be a device that generates an aerosol from an aerosol generating material using an ultrasonic vibration method. In this case, the ultrasonic vibration method may refer to a method of generating an aerosol by atomizing the aerosol generating material with ultrasonic vibrations generated by a vibrator.

[0044] As voltage (e.g., alternating voltage) is applied to the vibrator, heat and / or ultrasonic vibrations may be generated from the vibrator, and the heat and / or ultrasonic vibrations generated from the vibrator may be transferred to an aerosol-generating material absorbed by the wick. The aerosol-generating material absorbed by the wick may be converted into a gaseous phase by the heat and / or ultrasonic vibrations transferred from the vibrator, and as a result, an aerosol may be generated.

[0045] For example, the viscosity of the aerosol generating material absorbed by the wick may be lowered by heat generated from the vibrator, and the aerosol generating material with lowered viscosity may be finely atomized by ultrasonic vibrations generated from the vibrator, thereby generating an aerosol, but is not limited thereto.

[0046] In another embodiment, the aerosol generating device may be a device that generates an aerosol by heating an aerosol generating article housed in the aerosol generating device by an induction heating method.

[0047] An aerosol generating device may include a susceptor and a coil. In one embodiment, the coil may apply a magnetic field to the susceptor. As power is supplied to the coil from the aerosol generating device, a magnetic field may be formed inside the coil. In one embodiment, the susceptor may be a magnetic material that generates heat by an external magnetic field.

[0050] The embodiments of the present disclosure are described below with reference to the attached drawings so that those skilled in the art can easily implement them. The present disclosure may be implemented in a form that is feasible in the aerosol generating devices of the various embodiments described above, or may be implemented in various different forms, and is not limited to the embodiments described herein.

[0051] Embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0052] Hereinafter, examples of cigarettes (1) will be described with reference to FIGS. 1 and FIGS. 2.

[0053] Figures 1 and 2 are drawings illustrating examples of cigarettes.

[0054] Referring to FIG. 1, the cigarette (1) includes a tobacco rod (11) and a filter rod (12).

[0055] In FIG. 1, the filter rod (12) is depicted as a single segment, but is not limited thereto. In other words, the filter rod (12) may be composed of multiple segments. For example, the filter rod (12) may include a segment for cooling the aerosol and a segment for filtering certain components contained within the aerosol. Additionally, if necessary, the filter rod (12) may further include at least one segment that performs other functions.

[0056] The diameter of the cigarette (1) may be within the range of 5 mm to 9 mm, and the length may be about 48 mm, but is not limited thereto. For example, the length of the tobacco rod (11) may be about 12 mm, the length of the first segment of the filter rod (12) may be about 10 mm, the length of the second segment of the filter rod (12) may be about 14 mm, and the length of the third segment of the filter rod (12) may be about 12 mm, but is not limited thereto.

[0057] A cigarette (1) may be wrapped by at least one wrapper (14). The wrapper (14) may have at least one hole formed therein through which external air is introduced or internal gas is discharged. As an example, the cigarette (1) may be wrapped by one wrapper (14). As another example, the cigarette (1) may be wrapped in overlapping layers by two or more wrappers (14). For example, the tobacco rod (11) may be wrapped by the first wrapper (141), and the filter rod (12) may be wrapped by the wrappers (242, 243, 244). Then, the entire cigarette (1) may be re-wrapped by a single wrapper (145). If the filter rod (12) is composed of multiple segments, each segment may be wrapped by the wrappers (142, 143, 144).

[0058] The first wrapper (141) and the second wrapper (142) may be made of general filter paper. For example, the first wrapper (141) and the second wrapper (142) may be porous paper or non-porous paper. Additionally, the first wrapper (141) and the second wrapper (142) may be made of oil-resistant paper and / or aluminum laminate packaging material.

[0059] The third wrapper (143) may be made of hard paper. For example, the basis weight of the third wrapper (143) may be in the range of 88 g / m2 to 96 g / m2, and preferably in the range of 90 g / m2 to 94 g / m2. In addition, the thickness of the third wrapper (143) may be in the range of 120 µm to 130 µm, and preferably 125 µm.

[0060] The fourth wrapper (144) may be made of oil-resistant hard paper. For example, the basis weight of the fourth wrapper (144) may be in the range of 88 g / m2 to 96 g / m2, and preferably in the range of 90 g / m2 to 94 g / m2. In addition, the thickness of the fourth wrapper (144) may be in the range of 120 µm to 130 µm, and preferably 125 µm.

[0061] The fifth wrapper (145) may be made of sterile paper (MFW). Here, sterile paper (MFW) refers to paper specially manufactured to improve tensile strength, water resistance, smoothness, etc., compared to ordinary paper. For example, the basis weight of the fifth wrapper (145) may be in the range of 57 g / m2 to 63 g / m2, and preferably 60 g / m2. In addition, the thickness of the fifth wrapper (145) may be in the range of 64 µm to 70 µm, and preferably 67 µm.

[0062] The fifth wrapper (145) may have a specific material added thereto. Here, examples of the specific material may include silicone, but are not limited thereto. For example, silicone has properties such as heat resistance with minimal change with temperature, oxidation resistance that does not oxidize, resistance to various chemicals, water repellency, or electrical insulation. However, even if it is not silicone, any material having the aforementioned properties may be applied (or coated) to the fifth wrapper (145) without limitation.

[0063] The fifth wrapper (145) can prevent the phenomenon of the cigarette (1) burning. For example, if the cigarette rod (11) is heated by the heating element, there is a possibility that the cigarette (1) will burn. Specifically, if the temperature rises above the ignition point of any of the materials contained in the cigarette rod (11), the cigarette (1) may burn. Even in this case, since the fifth wrapper (145) contains a non-combustible material, the phenomenon of the cigarette (1) burning can be prevented.

[0064] Additionally, the fifth wrapper (145) can prevent the holder from being contaminated by substances generated from the cigarette (1). Liquid substances may be generated within the cigarette (1) by the user's puff. For example, liquid substances (e.g., moisture, etc.) may be generated by cooling an aerosol generated from the cigarette (1) by external air. As the fifth wrapper (145) wraps the cigarette (1), liquid substances generated within the cigarette (1) may be prevented from leaking out of the cigarette (1).

[0065] The tobacco rod (11) contains an aerosol-generating substance. For example, the aerosol-generating substance may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, but is not limited thereto. Additionally, the tobacco rod (11) may contain other additive substances such as flavoring agents, humectants, and / or organic acids. Additionally, a flavoring liquid, such as menthol or a humectant, may be added to the tobacco rod (11) by spraying it onto the tobacco rod (11).

[0066] The tobacco rod (11) can be manufactured in various ways. For example, the tobacco rod (11) may be made of a sheet or a strand. Additionally, the tobacco rod (11) may be made of finely cut tobacco sheets. Furthermore, the tobacco rod (11) may be surrounded by a heat-conducting material. For example, the heat-conducting material may be a metal foil such as aluminum foil, but is not limited thereto. For example, the heat-conducting material surrounding the tobacco rod (11) can evenly distribute the heat transferred to the tobacco rod (11), thereby improving the heat conductivity applied to the tobacco rod and improving the tobacco flavor. Additionally, the heat-conducting material surrounding the tobacco rod (11) can function as a susceptor heated by an induction heating heater. At this time, although not shown in the drawing, the tobacco rod (11) may include additional susceptors in addition to the heat-conducting material surrounding the outside.

[0067] The filter rod (12) may be a cellulose acetate filter. Meanwhile, there are no restrictions on the shape of the filter rod (12). For example, the filter rod (12) may be a cylindrical type rod or a tubular type rod containing a hollow interior. Additionally, the filter rod (12) may be a recessed type rod. If the filter rod (12) is composed of multiple segments, at least one of the multiple segments may be manufactured in a different shape.

[0068] The first segment of the filter rod (12) may be a cellulose acetate filter. For example, the first segment may be a tube-shaped structure containing a hollow interior. When a heating element is inserted through the first segment, the internal material of the tobacco rod (11) may be prevented from being pushed backward, and a cooling effect of the aerosol may also occur. The diameter of the hollow interior included in the first segment may be appropriately selected within the range of 2 mm to 4.5 mm, but is not limited thereto.

[0069] The length of the first segment may be appropriately adopted within the range of 4 mm to 30 mm, but is not limited thereto. Preferably, the length of the first segment may be 10 mm, but is not limited thereto.

[0070] The hardness of the first segment can be adjusted by controlling the content of the plasticizer during the manufacture of the first segment. Additionally, the first segment can be manufactured by inserting a structure, such as a film or tube, of the same or different material into its interior (e.g., hollow).

[0071] The second segment of the filter rod (12) cools the aerosol generated by the heating unit heating the tobacco rod (11). Thus, the user can inhale the aerosol cooled to a suitable temperature.

[0072] The length or diameter of the second segment can be varied depending on the shape of the cigarette (1). For example, the length of the second segment can be appropriately adopted within the range of 7 mm to 20 mm. Preferably, the length of the second segment can be about 14 mm, but is not limited thereto.

[0073] The second segment may be produced by weaving polymer fibers. In this case, a flavoring solution may be applied to the fibers made of polymer. Alternatively, the second segment may be produced by weaving a separate fiber coated with a flavoring solution together with a fiber made of polymer. Alternatively, the second segment may be formed by a crimped polymer sheet.

[0074] For example, the polymer can be made of a material selected from the group consisting of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), cellulose acetate (CA), and aluminum foil.

[0075] As the second segment is formed by woven polymer fibers or crimped polymer sheets, the second segment may include a single or multiple channels extending longitudinally. Here, a channel refers to a passage through which a gas (e.g., air or aerosol) passes.

[0076] For example, the second segment, which is made of a crimped polymer sheet, can be formed from a material having a thickness between about 5 μm and about 300 μm, for example, between about 10 μm and about 250 μm. Additionally, the total surface area of ​​the second segment can be between about 300 mm² / mm and about 1000 mm² / mm. Additionally, the aerosol cooling element can be formed from a material having a specific surface area between about 10 mm² / mg and about 100 mm² / mg.

[0077] Meanwhile, the second segment may include a thread containing a volatile flavor component. Here, the volatile flavor component may be menthol, but is not limited thereto. For example, the thread may be filled with a sufficient amount of menthol to provide 1.5 mg or more of menthol to the second segment.

[0078] The third segment of the filter rod (12) may be a cellulose acetate filter. The length of the third segment may be appropriately adopted within the range of 4 mm to 20 mm. For example, the length of the third segment may be about 12 mm, but is not limited thereto.

[0079] During the process of manufacturing the third segment, the third segment may be manufactured to generate flavor by spraying a flavoring liquid onto it. Alternatively, a separate fiber coated with a flavoring liquid may be inserted into the interior of the third segment. The aerosol generated in the tobacco rod (11) is cooled as it passes through the second segment of the filter rod (12), and the cooled aerosol is delivered to the user through the third segment. Therefore, if a flavoring element is added to the third segment, the effect of enhancing the persistence of the flavor delivered to the user may occur.

[0080] Additionally, the filter rod (12) may include at least one capsule (13). Here, the capsule (13) may perform the function of generating flavor or the function of generating aerosol. For example, the capsule (13) may be a structure in which a liquid containing a flavor is wrapped in a film. The capsule (13) may have a spherical or cylindrical shape, but is not limited thereto.

[0081] Referring to FIG. 2, the cigarette (2) may further include a shear plug (23). The shear plug (23) may be located on one side of the tobacco rod (21) opposite the filter rod (22). The shear plug (23) can prevent the tobacco rod (21) from moving outward and can prevent liquefied aerosol from the tobacco rod (21) from flowing into the aerosol generating device during smoking.

[0082] The filter load (22) may include a first segment (221) and a second segment (222). Here, the first segment (221) may correspond to the first segment of the filter load (12) of FIG. 1, and the second segment (222) may correspond to the third segment of the filter load (12) of FIG. 1.

[0083] The diameter and overall length of the cigarette (2) may correspond to the diameter and overall length of the cigarette (1) of FIG. 1. For example, the length of the shear plug (23) may be about 7 mm, the length of the tobacco rod (21) may be about 15 mm, the length of the first segment (221) may be about 12 mm, and the length of the second segment (222) may be about 14 mm, but is not limited thereto.

[0084] A cigarette (2) can be wrapped by at least one wrapper (25). At least one hole may be formed in the wrapper (25) through which external air is introduced or internal gas is discharged. For example, a shear plug (23) may be wrapped by a first wrapper (251), a tobacco rod (21) may be wrapped by a second wrapper (252), a first segment (221) may be wrapped by a third wrapper (253), and a second segment (222) may be wrapped by a fourth wrapper (254). Then, the entire cigarette (2) may be rewrapped by a fifth wrapper (255).

[0085] Additionally, at least one perforation (26) may be formed in the fifth wrapper (255). For example, the perforation (26) may be formed in an area surrounding the tobacco rod (21), but is not limited thereto. The perforation (26) may serve to transfer heat generated by the heating element into the interior of the tobacco rod (21).

[0086] Additionally, the second segment (222) may include at least one capsule (24). Here, the capsule (24) may perform the function of generating flavor or the function of generating aerosol. For example, the capsule (24) may be a structure in which a liquid containing a flavor is wrapped in a film. The capsule (24) may have a spherical or cylindrical shape, but is not limited thereto.

[0087] The first wrapper (251) may be a metal foil, such as aluminum foil, combined with a standard filter paper. For example, the total thickness of the first wrapper (251) may be within the range of 45 µm to 55 µm, preferably 50.3 µm. Additionally, the thickness of the metal foil of the first wrapper (251) may be within the range of 6 µm to 7 µm, preferably 6.3 µm. Furthermore, the basis weight of the first wrapper (251) may be within the range of 50 g / m2 to 55 g / m2, preferably 53 g / m2.

[0088] The second wrapper (252) and the third wrapper (253) can be made of general filter paper. For example, the second wrapper (252) and the third wrapper (253) can be porous paper or non-porous paper.

[0089] For example, the porosity of the second wrapper (252) may be 35,000 CU, but is not limited thereto. Also, the thickness of the second wrapper (252) may be within the range of 70 µm to 80 µm, and preferably 78 µm. Additionally, the basis weight of the second wrapper (252) may be within the range of 20 g / m2 to 25 g / m2, and preferably 23.5 g / m2.

[0090] For example, the porosity of the third wrapper (253) may be 24,000 CU, but is not limited thereto. Also, the thickness of the third wrapper (253) may be within the range of 60 µm to 70 µm, and preferably 68 µm. Additionally, the basis weight of the third wrapper (253) may be within the range of 20 g / m2 to 25 g / m2, and preferably 21 g / m2.

[0091] The fourth wrapper (254) may be made of PLA laminate. Here, PLA laminate refers to a three-layer paper comprising a paper layer, a PLA layer, and a paper layer. For example, the thickness of the fourth wrapper (254) may be within the range of 100 µm to 120 µm, and preferably 110 µm. Additionally, the basis weight of the fourth wrapper (254) may be within the range of 80 g / m2 to 100 g / m2, and preferably 88 g / m2.

[0092] The fifth wrapper (255) may be made of sterile paper (MFW). Here, sterile paper (MFW) refers to paper specially manufactured to improve tensile strength, water resistance, smoothness, etc., compared to ordinary paper.

[0099] FIG. 3 is a drawing illustrating examples of aerosol generating articles (3) according to various embodiments.

[0100] Referring to FIG. 3, the aerosol generating article (3) may include a medium rod (31) (e.g., the tobacco rod (11) of FIG. 1 or the tobacco rod (21) of FIG. 2), a filter rod (32) (e.g., the filter rod (12) of FIG. 1 and / or the filter rod (22) of FIG. 2)) and a wrapper (34) (e.g., the wrapper (14) of FIG. 1 or the wrapper (25) of FIG. 2).

[0101] In one embodiment, the medium rod (31) may be positioned at one end of the upstream side of the aerosol generating article (3). The medium rod (31) may consist of a tobacco medium (311) and a medium wrapper (341) (e.g., the first wrapper (141) of FIG. 1 or the second wrapper (252) of FIG. 2).

[0102] In one embodiment, the tobacco medium (311) may contain a functional substance (e.g., nicotine) and may be contained within the medium rod (31). For example, the tobacco medium (311) containing the functional substance may be in the form of nicotine granules, reconstituted tobacco, regular tobacco, or processed tobacco.

[0103] In one embodiment, the medium rod (31) may be made of a sheet, may be made of a strand, or may be made of finely cut tobacco sheets. Additionally, the medium rod (31) may be surrounded by a heat-conducting material. For example, the heat-conducting material may be a metal foil such as aluminum foil, but is not limited thereto.

[0104] In one embodiment, the filter rod (32) may be positioned on one side of the medium rod (31), and preferably, the filter rod (32) may be positioned to be in contact with the downstream end of the medium rod (31). The filter rod (32) may be positioned parallel to the medium rod (31) in the longitudinal direction. The filter rod (32) may be composed of a filter material (322) and a filter wrapper (343) (e.g., the third wrapper (143) of FIG. 1 or the third wrapper (253) of FIG. 2).

[0105] In one embodiment, the filter material (322) may be placed inside a filter wrapper (343) surrounding the filter rod (32). The filter material (322) may be placed on a path through which the aerosol is delivered from the upstream side to the downstream side of the aerosol generating article (3) and may serve to filter substances contained in the aerosol passing through it.

[0106] In one embodiment, the filter rod (32) may include a first fragrance (323) and a microcapsule (325). The microcapsule (325) may contain a second fragrance (326) inside. The microcapsule (325) may be in a shape having a size relatively smaller than a conventional capsule (e.g., capsule (24) of FIG. 2). A plurality of microcapsules (325) may be provided inside the filter material (322).

[0107] In various embodiments of this document, 'fragrances,' such as the first fragrance (323), the second fragrance (326), the third fragrance and the wrapper fragrance to be described later, may refer to functional substances that provide an olfactory scent to the user of the aerosol generating article (3), functional substances that provide a gustatory taste (or flavor), or functional substances that provide both scent and taste. For convenience of explanation, these are referred to as 'fragrances' in the following description, but are not limited thereto and may be replaced with terms such as 'sweetener,' 'functional substance,' 'chemical substance,' or 'preferable substance.'

[0108] In one embodiment, a plurality of particles of the first fragrance (323) and a plurality of microcapsules (325) may be dispersed and arranged over a wide area inside the filter material (322) by spraying them onto the filter material (322). The first fragrance (323) and the plurality of microcapsules (325) may be sprayed onto the filter material (322) through a TJNS (transfer jet nozzle system).

[0109] In one embodiment, the microcapsule (325) may have a size small enough not to be observed with the naked eye, or the microcapsule (325) may have a diameter in the micrometer range. The microcapsule (325) may have a structure that encloses the second fragrance (326), which is a liquid or solid containing the second fragrance (326), in a film.

[0110] In one embodiment, the first flavor (323) and / or the second flavor (326) may refer to particles or groups of particles of a liquid flavor solution. The first flavor (323) may be placed in a liquid solution state by being sprayed onto the filter material (322) through the TJNS. Alternatively, the first flavor (323) and / or the second flavor (326) may be solid flavor beads. For example, the first flavor (323) and / or the second flavor (326) may contain a solid menthol substance having volatility. Not limited thereto, the first flavor (323) and / or the second flavor (326) may consist of a chemical substance in various states (e.g., solid or liquid) capable of providing at least one of a scent and a taste to the user of the aerosol generating article (3).

[0111] In one embodiment, the microcapsules (325) may be crushed while the user is using the aerosol generating article (3). In the crushed microcapsules (325), the second flavor (326) inside may be exposed to the outside. The aerosol generating article (3) exposes the second flavor (326) during use and can enhance or alter the scent and / or taste for the user. Additionally, some of the multiple microcapsules (325) may be crushed sequentially or gradually. Compared to a relatively large size capsule, the multiple microcapsules (325) may expose a relatively small amount of the second flavor (326) to the filter material (322). As the user uses the aerosol generating article (3), the amount of exposure to the second flavor (326) increases, and the multiple microcapsules (325) can provide the user with a gradual and continuous enhancement or alteration of the scent and / or taste.

[0112] In one embodiment, the wrapper (34) may consist of a medium wrapper (341), a filter wrapper (343), and a tipping wrapper (345). The filter wrapper (343) may wrap a filter material (322), and the medium wrapper (341) may wrap a tobacco medium (311).

[0113] In one embodiment, the tipping wrapper (345) may be formed to wrap around the medium rod (31) and the filter rod (32). The tipping wrapper (345) wraps along the longitudinal direction of the aerosol generating article (3) and may surround the outer surface of the medium rod (31) and the filter rod (32). The tipping wrapper (345) may connect the medium rod (31) and the filter rod (32) by mutually joining one end of the medium rod (31) and one end of the filter rod (32).

[0114] FIG. 4 is a flowchart of a method (S100) for manufacturing an aerosol-generating article according to one embodiment.

[0115] Referring to FIG. 4, the method for manufacturing an aerosol generating article (S100) may include at least some of a medium rod forming operation (S110), a filter rod forming operation (S130), and a medium rod and filter rod combining operation (S150).

[0116] Hereinafter, a method (S100) for manufacturing an aerosol generating article according to various embodiments of the present document is described, and the subject of manufacturing may be the aerosol generating article described above (e.g., the cigarette (1) of FIG. 1, the cigarette (2) of FIG. 2, or the aerosol generating article (3) of FIG. 3), but is not limited thereto.

[0117] In one embodiment, the operation of forming a medium rod (S110) may form a medium rod containing a tobacco medium. The operation of forming a medium rod (S110) may include at least some of the following: a cigarette processing operation (S111), a tobacco medium forming operation (S112), and a tobacco medium wrapping operation (S113).

[0118] In one embodiment, the leaf processing operation (S111) can process leaf tobacco raw materials. For example, the leaf processing operation (S111) can perform various processing treatments such as malting, cutting, drying, conditioning, flavoring, and adding processes on various types of unprocessed leaf tobacco.

[0119] In one embodiment, the tobacco medium forming operation (S112) may form a tobacco medium containing the same using processed tobacco leaves. The tobacco medium wrapping operation (S113) may wrap the tobacco medium formed in the tobacco medium forming operation (S112) with a medium wrapper.

[0120] In one embodiment, the operation of forming a medium rod (S110) may be performed by cutting a wrapped tobacco medium to form a medium rod for use in an aerosol generating article. However, the operation of forming a medium rod (S110) described above is merely exemplary and is not limited thereto, and may be performed in various ways used in the industry when actually implemented.

[0121] In one embodiment, the filter load forming operation (S130) may include at least some of the filter material providing operation (S131), the first fragrance spraying operation (S133), the plurality of microcapsule spraying operations (S135), and the operation of wrapping the filter material (S137).

[0122] In one embodiment, the filter material supply operation (S131) ​​may supply a filter material to a TJNS (transfer jet nozzle system). The filter material may be a filter tow that has been cut to a predetermined length or processed.

[0123] In one embodiment, the first fragrance spraying operation (S133) may spray the first fragrance onto the filter material using TJNS. The first fragrance may provide the user of the aerosol generating article with a scent or taste before or at the time of use.

[0124] In one embodiment, a plurality of microcapsule spraying operations (S135) may spray a plurality of microcapsules containing a second fragrance into a filter material using TJNS. The plurality of microcapsules may be crushed during the user's use of the aerosol-generating article, thereby exposing the second fragrance to the filter material. The second fragrance may provide the user of the aerosol-generating article with a scent or taste during or after use.

[0125] In one embodiment, each of the plurality of microcapsules may have a small diameter in the micrometer range, and the amount of the second flavor contained therein may be relatively small in proportion to the diameter. Each of the plurality of microcapsules is gradually crushed during the process of the user using the aerosol generating article, and the amount of the second flavor exposed to the filter material may gradually or continuously increase. For example, compared to the case where a relatively large size capsule is crushed, the aerosol generating article containing the plurality of microcapsules may provide the user with a gradual or continuous boost or change in scent and / or flavor.

[0126] In one embodiment, the type or intensity of the fragrance provided to the user in the aerosol generating article can be adjusted to suit the preferences of various users. For example, the user can control the amount of exposure to the second fragrance by arbitrarily adjusting the crushing amount of a plurality of microcapsules according to their preference.

[0127] In one embodiment, the second fragrance may be composed of a substance that provides a scent different from the first fragrance. While using the aerosol generating article, the scent perceived by the user may change gradually or continuously as the amount of the second fragrance present in the filter material increases gradually or continuously.

[0128] In one embodiment, the second fragrance may be composed of a substance that provides substantially the same scent as the first fragrance. While using the aerosol generating article, the perceived scent may be gradually or continuously enhanced as the amount of the second fragrance present in the filter material gradually or continuously increases.

[0129] In one embodiment, the aerosol generating article can enhance user preference. For example, considering that the sense of smell adapts easily, the aerosol generating article according to various embodiments of this document can provide the user with a continuously intensifying or changing scent.

[0130] In one embodiment, each of the plurality of microcapsules may further contain a substance that provides a flavor (flovor). As with the second flavoring, the amount of the substance providing the flavor gradually increases in the filter material while using the aerosol generating article, and may provide the user with a continuously intensifying or changing taste. Alternatively, the user may control the amount of the exposed substance providing the flavor by arbitrarily adjusting the crushing amount of the plurality of microcapsules according to their preference. The type of flavor or the intensity of the flavor provided to the user by the aerosol generating article may be adjusted to suit various user preferences.

[0131] In one embodiment, the first fragrance spraying operation (S133) and the plurality of microcapsule spraying operations (S135) can be performed substantially simultaneously.

[0132] For example, when the filter material moves continuously along a rail, the first fragrance and a plurality of microcapsules may be sprayed simultaneously while the filter material is moving, so that the first fragrance and a plurality of microcapsules can be evenly distributed over the entire area of ​​the filter material. The production speed or production efficiency of the aerosol-generating article may be increased.

[0133] Alternatively, for example, when the filter material stops in a preset area while moving on a rail, the first fragrance and a plurality of microcapsules may be sprayed onto the filter material at the stopped position. It is easy to aim the spraying position of the first fragrance and the plurality of microcapsules, and the amount that bounces out of the filter material or is sprayed outside the filter material during spraying can be reduced.

[0134] In one embodiment, the first fragrance spraying operation (S133) and the plurality of microcapsule spraying operations (S135) may be performed sequentially and simultaneously. The plurality of microcapsule spraying operations (S135) may be performed after the first fragrance spraying operation (S133) is performed first, or the first fragrance spraying operation (S133) may be performed after the plurality of microcapsule spraying operations (S135) are performed first.

[0135] For example, when a filter material moves continuously along a rail, a first fragrance and a plurality of microcapsules may be sequentially sprayed while the filter material is moving, so that the first fragrance and the plurality of microcapsules are evenly distributed over the entire area of ​​the filter material. Factors such as the spraying amount and spraying speed of the first fragrance and the plurality of microcapsules may be controlled individually. Alternatively, the production speed or production efficiency of the aerosol-generating article may be increased.

[0136] Alternatively, for example, when the filter material stops in a preset area while moving on a rail, the first fragrance and a plurality of microcapsules may be sprayed onto the filter material at the stopped position. Factors such as the amount and speed of spraying the first fragrance and the plurality of microcapsules may be controlled in greater detail. Alternatively, it may be easy to aim the spraying position of the first fragrance and the plurality of microcapsules, and the amount that bounces out of the filter material or is sprayed outside the filter material during spraying may be reduced.

[0137] In one embodiment, the operation of wrapping the filter material (S137) may wrap the filter material, which has been sprayed with the first fragrance and a plurality of microcapsules, with a filter wrapper. In one embodiment, the operation of forming the filter rod (S130) may cut the wrapped filter material to form a filter rod for use in a single aerosol generating article. However, the operation of forming the filter rod (S130) described above is merely exemplary and is not limited thereto, and may be carried out in various ways used in the industry.

[0138] In one embodiment, the medium rod and filter rod combining operation (S150) can combine the medium rod and filter rod by wrapping the medium rod formed in the medium rod forming operation (S110) and the filter rod formed in the filter rod forming operation (S130) with a tipping wrapper.

[0139] Hereinafter, with reference to FIGS. 5, 6, 7, and 8, a detailed manufacturing process of a filter rod forming operation (S130) is described exemplarily with reference to the manufacturing method (S100) of an aerosol generating article according to various embodiments described above, and details that overlap with the above description are omitted.

[0140] FIG. 5 is a flowchart of a filter rod forming operation (S130) of a method for manufacturing an aerosol generating article according to one embodiment (e.g., method for manufacturing an aerosol generating article of FIG. 4 (S100)).

[0141] Referring to FIG. 5, TJNS may include a first nozzle and a second nozzle, and the filter rod forming operation (S130) may spray a first fragrance and a plurality of microcapsules using the first nozzle and the second nozzle.

[0142] In one embodiment, the first fragrance spraying operation (S133) may include a first nozzle spraying operation (S133a), and the first nozzle spraying operation (S133a) may spray the first fragrance onto the filter material through the first nozzle. A plurality of microcapsule spraying operations (S135) may include a second nozzle spraying operation (S135a), and the second nozzle spraying operation (S135a) may spray a plurality of microcapsules onto the filter material through a second nozzle different from the first nozzle.

[0143] In one embodiment, the first nozzle and the second nozzle may be arranged separately from each other and may each spray a first fragrance and a plurality of microcapsules onto a filter material. The first nozzle and the second nozzle may be arranged adjacent to or in close contact with each other. Alternatively, the first nozzle and the second nozzle may be arranged spaced apart from each other along the direction of movement of the rail on which the filter material moves.

[0144] In one embodiment, the first nozzle and the second nozzle can individually control detailed elements such as the spray amount, spray density, and spray position, and the method for manufacturing an aerosol generating article (S100) can form a filter rod by spraying a first fragrance and a plurality of microcapsules to suit various palatability.

[0145] FIG. 6 is a flowchart of a filter rod forming operation (S130) of a method for manufacturing an aerosol generating article according to one embodiment (e.g., method for manufacturing an aerosol generating article of FIG. 4 (S100)).

[0146] Referring to FIG. 6, TJNS may include an integrated nozzle, and the filter load forming operation (S130) may spray a first fragrance and a plurality of microcapsules using the integrated nozzle.

[0147] In one embodiment, the first fragrance spraying operation (S133) may be performed simultaneously with a plurality of microcapsule spraying operations (S135), each of which may include an integrated nozzle spraying operation (S134). For example, the first fragrance spraying operation (S133) may spray a first fragrance onto a filter material through an integrated nozzle, and the plurality of microcapsule spraying operations (S135) may spray a plurality of microcapsules onto a filter material through the same integrated nozzle as the first fragrance spraying operation (S133).

[0148] In one embodiment, the integrated nozzle can simultaneously spray a first fragrance and a plurality of microcapsules as a filter material. By mixing and introducing the fragrance and a plurality of microcapsules into a TJNS comprising a single nozzle, the structure and operation of the TJNS can be simplified, and the method for manufacturing an aerosol generating article (S100) according to one embodiment of this document can be applied to a TJNS that sprays only the fragrance. Alternatively, the method for manufacturing an aerosol generating article (S100) can shorten the movement path of the filter material by spraying the first fragrance and a plurality of microcapsules at the same location.

[0149] FIG. 7 is a flowchart of a filter rod forming operation (S130) of a method for manufacturing an aerosol generating article according to one embodiment (e.g., method for manufacturing an aerosol generating article of FIG. 4 (S100)).

[0150] Referring to FIG. 7, TJNS may include a first sub-nozzle and a second sub-nozzle, and the filter load forming operation (S130) may spray a first microcapsule and a second microcapsule, respectively, using the first sub-nozzle and the second sub-nozzle.

[0151] In one embodiment, the operation of spraying a plurality of microcapsules (S135) may spray a first microcapsule containing a second fragrance and a second microcapsule containing a third fragrance different from the second fragrance onto a filter material, respectively.

[0152] In one embodiment, the first microcapsule and the second microcapsule include flavorings that provide different scents and / or flavors, so that the aerosol generating article can provide at least two or more changes in scent and / or flavor to the user.

[0153] In one embodiment, the third fragrance may be composed of a substance that provides a scent different from the first fragrance, and accordingly, any one of the first fragrance, the second fragrance, and the third fragrance may provide a scent different from the others. The aerosol generating article may provide the user with three changes of scent gradually or continuously through the first fragrance, the second fragrance, and the third fragrance.

[0154] In one embodiment, the third flavor may be composed of a substance that provides a flavor substantially identical to the first flavor. The second microcapsule may provide a gradual or continuous enhancement of a flavor or taste substantially identical to the first flavor. The first microcapsule may provide a gradual and continuous change of a flavor or taste different from the first flavor.

[0155] In one embodiment, the operation of spraying a plurality of microcapsules (S135) may include the operation of spraying a first microcapsule onto a filter material through a first sub-nozzle (S135b) and the operation of spraying a second microcapsule onto a filter material through a second sub-nozzle (S135c).

[0156] In one embodiment, the first sub-nozzle and the second sub-nozzle may be included in the second nozzle, and in this case, the operation of spraying the first microcapsule (S135b) and the operation of spraying the second microcapsule (S135c) may be part of the operation of the second nozzle spraying operation (S135a).

[0157] In one embodiment, detailed elements such as the injection amount, injection density, and injection position of the first sub-nozzle and the second sub-nozzle can be individually controlled, and the method for manufacturing an aerosol generating article (S100) can form a filter rod by injecting the first microcapsule and the second microcapsule to suit various preferences.

[0158] In various embodiments of the present document, a plurality of microcapsules may further include a third microcapsule containing a fourth flavor that provides a taste or scent different from the first flavor, the second flavor, and the third flavor, and may provide the user with a gradual or continuous enhancement or change of at least three flavors or tastes.

[0159] FIG. 8 is a flowchart of a filter rod forming operation (S130) of a method for manufacturing an aerosol generating article according to one embodiment (e.g., method for manufacturing an aerosol generating article of FIG. 4 (S100)).

[0160] Referring to FIG. 8, the filter load forming operation (S130) may further include a wrapper flavor addition operation (S136).

[0161] In one embodiment, the wrapper fragrance addition operation (S136) may be performed prior to the operation of wrapping the filter material (S137). Unlike as illustrated in FIG. 8, the wrapper fragrance addition operation (S136) is independent of the order of the other operations (S131, S133, S135) and may be performed, for example, prior to or simultaneously.

[0162] In one embodiment, the wrapper flavor addition operation (S136) may add a wrapper flavor to the filter wrapper. The wrapper flavor may provide a scent or taste to the user of the aerosol generating article.

[0163] In one embodiment, the wrapper flavoring may provide the user of the aerosol generating article with a scent or taste before or at the time of use. A plurality of microcapsules may be crushed during the user's use of the aerosol generating article and may expose the second flavoring to a filter material, and the second flavoring may provide the user of the aerosol generating article with a taste during or after use.

[0164] In one embodiment, the wrapper flavoring may be composed of a substance that provides a taste different from the second flavoring. While using the aerosol generating article, the taste perceived by the user may change gradually or continuously as the amount of the second flavoring present in the filter material increases gradually or continuously.

[0165] In one embodiment, the wrapper flavor may be composed of a substance that provides substantially the same taste as the second flavor. While using the aerosol generating article, the perceived taste may be gradually or continuously enhanced as the amount of the second flavor present in the filter material gradually or continuously increases.

[0166] Although the embodiments have been described above with reference to the limited drawings, those skilled in the art can apply various technical modifications and variations based on the above. For example, suitable results may be achieved even if the described techniques are performed in a different order than described, and / or if the components of the described system, structure, device, circuit, etc. are combined or assembled in a form different from described, or replaced or substituted by other components or equivalents.

[0167] Therefore, other implementations, other embodiments, and equivalents to the claims also fall within the scope of the claims set forth below.
