[0028] As used herein, expressions such as "at least one" preceding a list of components do not modify each of the listed components, but rather modify all of the components. For example, the expression "at least one of a, b, or c" should be interpreted as including a, b, c, including a and b, including a and c, including b and c, or including a, b and c.

[0029] In the following embodiments, "aerosol generating article" as an article for containing a medium refers to an article that transfers the medium as aerosol passes through the corresponding article. A representative example of an aerosol generating article is a cigarette, but the scope of the present disclosure is not limited thereto.

[0030] In the following embodiments, "upstream" or "upstream direction" refers to the direction away from the user's (smoker's) mouth; "downstream" or "downstream direction" refers to the direction close to the user's mouth. Upstream and downstream are used to describe the relative positions of various parts of the aerosol generating article.

[0031] In the following embodiments, "puff" refers to inhalation by a user, and inhalation refers to a situation where a user inhales into the user's oral cavity, nasal cavity, or lungs through the mouth or nose.

[0032] In one embodiment, the aerosol generating device may be a device that generates aerosol by electrically heating an aerosol generating article contained in an internal space thereof.

[0033] The aerosol generating device may include a heater. In one embodiment, the heater may be a resistive heater. For example, the heater may include an electrically conductive track, and when an electric current flows on the electrically conductive track, the heater is heated.

[0034] The heater may include at least one of a tubular heating element, a plate heating element, a needle heating element or a rod heating element, and the inside or the outside of the aerosol generating article may be heated according to the shape of the heating element.

[0035] The aerosol generating article may include a cigarette rod and a filter rod. The cigarette rod may be made of a sheet, or may be made of tobacco strands, or may be made of tobacco strands cut from tobacco sheets. Furthermore, the cigarette rod may be wrapped with a heat conductive material. For example, a non-limiting example of a heat conductive material is a metal foil such as aluminum foil.

[0036] The filter rod may be a cellulose acetate filter rod. The filter rod may have at least one segment. For example, the filter rod may include a first segment for cooling the aerosol and a second segment for filtering a predetermined component contained in the aerosol.

[0037] In one embodiment, the aerosol generating device may generate aerosol using a cartridge containing an aerosol generating substance.

[0038] The aerosol generating device may include a cartridge containing 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 and the main body may be formed integrally or assembled, and the cartridge may be fixed to prevent separation due to the user. The cartridge may be mounted to the main body in a state in which the aerosol generating substance is contained. However, the embodiment is not limited thereto, and the aerosol generating substance may also be injected into the cartridge in a state in which the cartridge is coupled to the main body.

[0039] The cigarette cartridge may contain an aerosol-generating substance in any state such as liquid, solid, gaseous, or gel. The aerosol-generating substance may include a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing substance containing a volatile tobacco aroma component, or may be a liquid containing a non-tobacco-containing substance.

[0040] The cartridge can be operated based on an electrical signal or radio signal transmitted by the main body, and the aerosol generating substance inside the cartridge can be changed into a gas by a phase change, thereby realizing the function of generating an aerosol. The aerosol can refer to a mixed gas of steam particles and air generated from the aerosol generating substance.

[0041] In another embodiment, the aerosol generating device can generate an aerosol by heating a liquid composition, and deliver the generated aerosol to a user through a cigarette. That is, the aerosol generated by the liquid composition can move along the airflow channel of the aerosol generating device, and the airflow channel enables the aerosol to be delivered to the user via the cigarette.

[0042] In another embodiment, the aerosol generating device may be a device that generates aerosol from an aerosol generating substance by ultrasonic vibration. In this case, the ultrasonic vibration method may refer to a method of generating aerosol by atomizing the aerosol generating substance by ultrasonic vibration generated by a vibrator.

[0043] The aerosol generating device may include a vibrator, and the vibrator may generate short-period vibrations to atomize the aerosol generating substance. The vibration generated by the vibrator may be ultrasonic vibrations, and the frequency band of the ultrasonic vibrations may be about 100 kHz to about 3.5 MHz, but the embodiment is not limited thereto.

[0044] The aerosol generating device may further comprise a core that absorbs the aerosol generating substance.For example, the core may wrap around at least one region of the vibrator or contact at least one region of the vibrator.

[0045] When a voltage (e.g., an alternating voltage) is applied to the vibrator, the vibrator may generate heat and / or ultrasonic vibrations, and the heat and / or ultrasonic vibrations generated by the vibrator may be transmitted to the aerosol-generating substance absorbed by the core. The aerosol-generating substance absorbed by the core may undergo a phase change and be converted into a gas by the heat and / or ultrasonic vibrations transmitted by the vibrator, and finally generate an aerosol.

[0046] For example, the viscosity of the aerosol generating material absorbed by the core is reduced by the heat generated by the vibrator, and the aerosol generating material whose viscosity is reduced by the ultrasonic vibration generated by the vibrator becomes fine particles, thereby generating aerosol, but is not limited thereto.

[0047] In yet another embodiment, the aerosol generating device may be a device that generates an aerosol by heating an aerosol generating article contained in the aerosol generating device by induction heating.

[0048] The aerosol generating device may include a susceptor and a coil. In one embodiment, the coil may apply a magnetic field to the susceptor. When the aerosol generating device supplies power to the coil, a magnetic field may be formed within the coil. In one embodiment, the susceptor may be a magnetic element that generates heat through an external magnetic field.

[0051] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings to help those skilled in the art to easily implement the present disclosure. The present disclosure can be implemented in a form that can be implemented in the aerosol generating device of the various embodiments described above, or can be implemented in various different forms, and is not limited to the embodiments described herein.

[0052] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0053] Refer to the following Figure 1 and Figure 2 An example of a cigarette 1 will be described.

[0054] Figure 1 and Figure 2 is a diagram showing an example of a cigarette.

[0055] Reference Figure 1 The cigarette 1 may include a cigarette rod 11 and a filter rod 12 .

[0056] Although the filter rod 12 is Figure 1 1 is shown as having a single segment, but is not limited thereto. In other words, the filter rod 12 may include a plurality of segments. For example, the filter rod 12 may include a segment for cooling the aerosol and a segment for filtering a component contained in the aerosol. In addition, as required, the filter rod 12 may also include at least one segment that performs another function.

[0057] The diameter of the cigarette 1 may be in 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 cigarette rod 11 may be about 12 mm, the length of the first section of the filter rod 12 may be about 10 mm, the length of the second section of the filter rod 12 may be about 14 mm, and the length of the third section of the filter rod 12 may be about 12 mm, but is not limited thereto.

[0058] The cigarette 1 may be wrapped with at least one wrapping paper 14. The wrapping paper 14 may have at least one hole through which external air is introduced or internal gas is discharged to the outside. For example, the cigarette 1 may be wrapped with one wrapping paper 14. As another example, the cigarette 1 may be wrapped with two or more wrapping papers 14 in an overlapping manner. For example, the cigarette rod 11 may be wrapped with a first wrapping paper 141, and the filter rod 12 may be wrapped with wrapping papers 242, 243, and 244. In addition, the entire cigarette 1 may be wrapped again with a single wrapping paper 145. For example, when the filter rod 12 includes a plurality of segments, each of the plurality of segments may be wrapped with wrapping papers 142, 143, and 144.

[0059] The first wrapping paper 141 and the second wrapping paper 142 can be formed of ordinary filter rod paper. For example, the first wrapping paper 141 and the second wrapping paper 142 can be porous cigarette paper or non-porous cigarette paper. In addition, the first wrapping paper 141 and the second wrapping paper 142 can be made of oil-resistant paper and / or aluminum laminated packaging material.

[0060] The third wrapping paper 143 may be formed of hard cigarette paper. For example, the basis weight of the third wrapping paper 143 may be 88 grams per square meter (g / m 2 ) to 96g / m 2 In the range of 90g / m 2 Up to 94g / m 2 In addition, the thickness of the third wrapping paper 143 may be in the range of 120 μm to 130 μm, and preferably may be 125 μm.

[0061] The fourth wrapping paper 144 can be made of oil-resistant hard cigarette paper. For example, the basis weight of the fourth wrapping paper 144 can be 88g / m 2 Up to 96g / m 2 In the range of 90g / m 2 Up to 94g / m 2 In addition, the thickness of the fourth wrapping paper 144 may be in the range of 120 μm to 130 μm, and desirably may be 125 μm.

[0062] The fifth wrapping paper 145 may be made of sterile paper (e.g., MFW). Here, sterile paper (MFW) may refer to paper specially manufactured to improve tensile strength, water resistance, smoothness, etc. compared to ordinary paper. For example, the basis weight of the fifth wrapping paper 145 may be 57 g / m 2 Up to 63g / m 2 and may be about 60 g / m 2In addition, the thickness of the fifth wrapping paper 145 may be in the range of 64 μm to 70 μm, and preferably may be 67 μm.

[0063] The fifth wrapping paper 145 may have a predetermined material added inside. The material may be, for example, silicon. But it is not limited thereto. For example, silicon has the following properties: heat resistance with little change with temperature, oxidation resistance without oxidation, resistance to various drugs, water resistance or electrical insulation, etc. However, even if it is not silicon, any material having the above properties may be applied (or coated) to the fifth wrapping paper 145 without restriction.

[0064] The fifth wrapping paper 145 can prevent the cigarette 1 from burning. For example, when the cigarette rod 11 is heated by the heating unit, the cigarette 1 may burn. Specifically, when the temperature rises above the ignition point of any material contained in the cigarette rod 11, the cigarette 1 may burn. Even in this case, since the fifth wrapping paper 145 contains a non-combustible material, the cigarette 1 can be prevented from burning.

[0065] In addition, the fifth wrapping paper 145 can prevent the mouthpiece from being contaminated by substances generated by the cigarette 1. For example, liquid substances may be generated in the cigarette 1 through the user's inhalation. For example, when the aerosol generated by the cigarette 1 is cooled by the external air, liquid substances (e.g., moisture, etc.) may be generated. Therefore, wrapping the cigarette 1 with the fifth wrapping paper 145 can prevent the liquid substances generated in the cigarette 1 from leaking to the outside of the cigarette 1.

[0066] The tobacco rod 11 may contain an aerosol-generating substance. The aerosol-generating substance may include, for example, at least one of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, but is not limited thereto. The tobacco rod 11 may also contain other additives, such as flavoring agents, wetting agents, and / or organic acids. In addition, a flavoring liquid such as menthol or a humectant may be added to the tobacco rod 11 by spraying it on the tobacco rod 11.

[0067] The cigarette rod 11 can be manufactured in various forms. The cigarette rod 11 can be made of a sheet, or it can be made of strands, or it can be made of strands cut from tobacco sheets. In addition, the cigarette rod 11 can be wrapped with a thermally conductive material. For example, a non-limiting example of a thermally conductive material is a metal foil such as aluminum foil. But it is not limited to this. For example, the thermally conductive material wrapping the cigarette rod 11 can improve the thermal conductivity applied to the cigarette rod by evenly dispersing the heat transferred to the cigarette rod 11, thereby improving the taste of the tobacco. In addition, the thermally conductive material wrapping the cigarette rod 11 can be used as a receptor heated by an induction heater. In this case, although not shown, the cigarette rod 11 may include an additional receptor in addition to the thermally conductive material wrapping the outside thereof.

[0068] The filter rod 12 may be a cellulose acetate filter rod. However, there is no limitation on the shape of the filter rod 12. For example, the filter rod 12 may be a cylindrical rod, or a tubular rod with a hollow interior. Also, the filter rod 12 may be a recessed rod. For example, when the filter rod 12 includes a plurality of segments, at least one of the plurality of segments may be manufactured in a different shape.

[0069] The first section of the filter rod 12 may be a cellulose acetate filter rod. For example, the first section may be a tubular structure with a hollow interior. When the first section is inserted into the heater 13, the inner material of the cigarette rod 11 may be prevented from being pushed back, and an aerosol cooling effect may be produced. The diameter of the hollow included in the first section may be appropriately adopted within the range of 2 mm to 4.5 mm. However, it is not limited thereto.

[0070] The length of the first section can be appropriately adopted in the range of 4 mm to 30 mm, but is not limited thereto. Preferably, the length of the first section can be about 10 mm, but is not limited thereto.

[0071] The hardness of the first segment can be adjusted by adjusting the content of the plasticizer during the manufacturing process of the first segment. In addition, the first segment can be manufactured by inserting a structure such as a film or tube made of the same or different material inside (eg, hollow).

[0072] The second section of the filter rod 12 can cool the aerosol generated when the heating portion heats the cigarette rod 11. Therefore, the user can inhale the aerosol cooled to a suitable temperature.

[0073] The length or diameter of the second segment can be determined in various ways according to the shape of the cigarette 1. For example, the length of the second segment can be appropriately adopted in the range of 7 mm to 20 mm. Preferably, the length of the second segment can be about 14 mm. But it is not limited thereto.

[0074] The second section may be made by weaving polymer fibers. In this case, the flavoring liquid may be applied to the fibers made of the polymer. Alternatively, the second section may be made by weaving together separate fibers to which the flavoring liquid is applied and fibers made of the polymer. Alternatively, the second section may be formed of a curled polymer sheet.

[0075] For example, the polymer may be prepared with 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.

[0076] Since the second section is formed by woven polymer fibers or curled polymer sheets, the second section may include a longitudinally extending channel or channels. Here, the channel may refer to a channel through which a gas (eg, air or aerosol) passes.

[0077] For example, the second segment formed of the rolled polymer sheet may be formed of a material having a thickness between about 5 μm and about 300 μm, such as a material having a thickness between about 10 μm and about 250 μm. In addition, the total surface area of ​​the second segment may be about 300 mm 2 / mm and about 1000mm 2 / mm. In addition, the aerosol-cooling element can be composed of a specific surface area of ​​about 10mm 2 / mg and about 100mm 2 / mg of material is formed.

[0078] On the other hand, the second segment may include a thread containing a volatile flavor component. 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 at least 1.5 milligrams (mg) of menthol to the second segment.

[0079] The third section of the filter rod 12 may be a cellulose acetate filter. The length of the third section may be appropriately adopted in the range of 4 mm to 20 mm. For example, the length of the third section may be about 12 mm, but is not limited thereto.

[0080] In the process of manufacturing the third segment, the third segment can be manufactured to generate flavor by spraying flavoring liquid to the third segment. Alternatively, a separate fiber coated with flavoring liquid can be inserted into the interior of the third segment. The aerosol generated in the cigarette rod 11 can be cooled when it passes through the second segment of the filter rod 12, and the cooled aerosol can be delivered to the user through the third segment. Therefore, when the flavoring element is added to the third segment, the persistence of the flavor delivered to the user can be improved.

[0081] In addition, the filter rod 12 may include at least one capsule 13. The capsule 13 may perform a function of generating flavor or a function of generating aerosol. For example, the capsule 13 may be a structure in which a liquid containing a flavor is wrapped with a film. The capsule 13 may have a spherical or cylindrical shape, but is not limited thereto.

[0082] Reference Figure 2 The cigarette 2 may further include a front end plug 23. The front end plug 23 may be arranged on a side of the cigarette rod 21 opposite to the filter rod 22. The front end plug 23 may prevent the cigarette rod 21 from being separated from the outside, and may prevent the aerosol liquefied from the cigarette rod 21 from flowing into the aerosol generating device during smoking.

[0083] The filter rod 22 may include a first section 221 and a second section 222. Here, the first section 221 may correspond to Figure 1 The first section of the filter rod 12, and the second section 222 may correspond to Figure 1 The third section of the filter rod 12.

[0084] The diameter and overall length of the cigarette 2 may correspond to Figure 1 The diameter and total length of the cigarette 1. For example, the length of the front end plug 23 may be about 7 mm, the length of the cigarette rod 21 may be about 15 mm, the length of the first section 221 may be about 12 mm, and the length of the second section 222 may be about 14 mm, but are not limited thereto.

[0085] The cigarette 2 may be wrapped with at least one wrapping paper 25. The wrapping paper 25 may have at least one hole through which external air flows in or through which internal gas flows out. For example, the front end plug 23 may be wrapped with a first wrapping paper 251, the cigarette rod 21 may be wrapped with a second wrapping paper 252, the first section 221 may be wrapped with a third wrapping paper 253, and the second section 222 may be wrapped with a fourth wrapping paper 254. In addition, the entire cigarette 2 may be rewrapped with a fifth wrapping paper 255.

[0086] In addition, at least one perforation 26 may be formed in the fifth wrapping paper 255. For example, the perforation 26 may be formed in a region surrounding the cigarette rod 21, but is not limited thereto. The perforation 26 may perform the function of transferring the heat generated by the heating portion to the inside of the cigarette rod 21.

[0087] In addition, the second section 222 may include at least one capsule 24. Here, the capsule 24 may perform a function of generating flavor or a function of generating aerosol. For example, the capsule 24 may have a structure in which a liquid containing a flavor is wrapped with a film. The capsule 24 may have a spherical or cylindrical shape, but is not limited thereto.

[0088] The first wrapping paper 251 may be a combination of a metal foil such as an aluminum foil and a normal filter rod paper. For example, the total thickness of the first wrapping paper 251 may be in the range of 45 μm to 55 μm, and preferably may be about 50.3 μm. In addition, the thickness of the metal foil of the first wrapping paper 251 may be in the range of 6 μm to 7 μm, and preferably may be about 6.3 μm. In addition, the basis weight of the first wrapping paper 251 may be 50 g / m 2 Up to 55g / m 2 The range of and preferably may be about 53 g / m 2 .

[0089] The second wrapping paper 252 and the third wrapping paper 253 can be formed by ordinary filter rod paper. For example, the second wrapping paper 252 and the third wrapping paper 253 can be porous cigarette paper or non-porous cigarette paper.

[0090] For example, the porosity of the second wrapping paper 252 may be 35000 CU, but is not limited thereto. In addition, the thickness of the second wrapping paper 252 may be in the range of 70 μm to 80 μm, and preferably may be about 78 μm. In addition, the basis weight of the second wrapping paper 252 may be 20 g / m 2 Up to 25g / m 2 The range of and preferably may be about 23.5 g / m 2 .

[0091] For example, the porosity of the third wrapping paper 253 may be 24000 CU, but is not limited thereto. In addition, the thickness of the third wrapping paper 253 may be in the range of 60 μm to 70 μm, and preferably may be about 68 μm. In addition, the basis weight of the third wrapping paper 253 may be 20 g / m 2 Up to 25g / m 2 The range of and preferably may be about 21g / m 2 .

[0092] The fourth wrapping paper 254 may be made of polylactic acid (PLA) laminated paper. Here, PLA laminated paper may refer to a three-layer paper including a paper layer, a PLA layer, and a paper layer. For example, the thickness of the fourth wrapping paper 254 may be in the range of 100 μm to 120 μm, and preferably may be about 110 μm. In addition, the basis weight of the fourth wrapping paper 254 may be 80 g / m 2 Up to 100g / m 2 The range of and preferably can be about 88g / m 2 .

[0093] The fifth wrapping paper 255 may be made of sterile paper (e.g., MFW). Here, sterile paper (MFW) may refer to paper specially made to improve tensile strength, water resistance, smoothness, etc. compared with ordinary paper. For example, the basis weight of the fifth wrapping paper 255 may be 57 g / m 2 Up to 63g / m 2 The range of and preferably may be about 60g / m 2 In addition, the thickness of the fifth wrapping paper 255 may be in the range of 64 μm to 70 μm, and preferably may be about 67 μm.

[0101] In one embodiment, the aerosol generating article 3 comprises the aerosol generating article of the aforementioned embodiment (e.g., Figure 1 Aerosol-generating articles 1 or Figure 2 All parts of an aerosol generating article 2). Figure 1 and Figure 2 The aerosol generating articles (e.g., Figure 1 Aerosol-generating articles 1 or Figure 2 These are common components of the aerosol generating article 2), so repeated content will be omitted below.

[0102] In one embodiment, the aerosol generating article 3 includes a first end face 3a, a second end face 3b formed on the opposite side of the first end face 3a, and a side face 3c formed between the first end face 3a and the second end face 3b. In one embodiment, the aerosol generating article 3 includes a medium segment 31, a first segment 32 arranged on the downstream side of the medium segment 31, a second segment 33 arranged on the upstream side of the medium segment 31, an inner cigarette paper 34, and an outer wrapping paper 35.

[0103] In one embodiment, the medium segment 31 may include a medium. For example, the medium may include a solid substance based on tobacco raw materials (e.g., tobacco leaves, tobacco shreds, reconstituted tobacco, etc.) and / or a liquid composition based on nicotine, cigarette extracts or other flavoring agents, but is not necessarily limited thereto. For example, the medium segment according to one embodiment may be attached by compressing a slurry medium. In one embodiment, the medium segment 31 may include a hollow tube 31a. In one embodiment, the aerosol generated when the medium segment 31 is heated may flow to the second end surface 3b through the hollow tube 31a formed at the center of the medium segment 31.

In one embodiment, the medium segment 31 may include a frame 312 and a medium portion 314. In one embodiment, the frame 312 may be cylindrical. In one embodiment, the frame 312 may be used as a substrate for coating the medium portion 314. In one embodiment, the frame 312 may be made of materials such as paper, synthetic resin, non-ferrous metal, etc. In one embodiment, the medium portion 314 may be arranged around the outer surface of the frame 312. In one embodiment, the media portion 314 of the media segment 31 may be exposed to the outside of the aerosol-generating article 3. For example, the media segment 31 may be in a state where the surrounding wrapping papers 34, 35 are removed.

[0104] In one embodiment, the first section 32 may abut against the downstream side of the medium section 31. According to one embodiment, the first section 32 may include a cooling portion 321 and a filtering portion 322. According to one embodiment, the cooling portion 321 may include a cavity therein. In one embodiment, the cooling portion 321 may cool the aerosol generated by the medium section 31. In one embodiment, although the filtering portion 322 is Figure 3A322 is shown as a single segment, but is not limited to this. In other words, the filter portion 322 may include a plurality of segments. For example, the filter portion 322 may include a segment for cooling the aerosol and a segment for filtering a predetermined component contained in the aerosol. In addition, as needed, the filter portion 322 may also include at least one segment that performs another function. The filter portion 322 may be a cellulose acetate filter. However, the shape of the filter portion 322 is not limited. For example, the filter portion 322 may be a cylindrical rod, or a tubular rod with a hollow interior, or a recessed rod.

[0105] In one embodiment, the second section 33 can prevent the medium of the medium section 31 from detaching. For example, the second section 33 can include a front end plug. The front end plug can be arranged on a side opposite to the first section 32. In one embodiment, the front end plug can prevent the medium from detaching to the outside, and can also prevent the aerosol liquefied from the medium section during smoking from flowing into the aerosol generating device. In one embodiment, the front end plug can be made of cellulose acetate. For example, the front end plug can be prepared by adding a plasticizer (e.g., triacetin) to the cellulose acetate tow. In one embodiment, the cross-section of the filament constituting the front end plug can be Y-shaped. In one embodiment, the front end plug can include at least one channel, and the cross-section of the channel can be manufactured in a variety of ways.

[0106] In one embodiment, at least one wrapping paper 34, 35 is used to wrap the aerosol-generating article 3. In one embodiment, the wrapping paper 34, 35 may include an inner cigarette paper 34 and an outer cigarette paper 35. In one embodiment, the inner cigarette paper 34 wraps at least a portion of the side of the first section 32 and the second section. In one embodiment, the inner cigarette paper 34 includes a first inner cigarette paper 341 wrapping at least a portion of the second section 33 and a second inner cigarette paper 342 wrapping at least a portion of the first section 32. The inner cigarette paper 34 may be a porous cigarette paper or a non-porous cigarette paper. In addition, the inner cigarette paper 34 may be made of oil-resistant paper and / or an aluminum laminated packaging material. In one embodiment, the outer cigarette paper 35 may wrap the outermost edge of the side 3c of the aerosol-generating article 3, thereby maintaining the shape of the aerosol-generating article 3. In one embodiment, the outer cigarette paper 35 includes a first cigarette paper 351 wrapping at least a portion of the second section 33 and a second cigarette paper 352 wrapping at least a portion of the first section 32. The outer wrapper 35 can prevent the aerosol-generating article 3 from burning. For example, the aerosol-generating article 3 may burn when the temperature rises above the ignition point of any material included in the medium segment 31. In this case, since the outer wrapper 35 includes a non-combustible material, the aerosol-generating article 3 can be prevented from burning.

[0107] In addition, the outer wrapping paper 35 can prevent the mouthpiece from being contaminated by substances generated in the aerosol generating article 3. Liquid substances may be generated in the aerosol generating article 3 by the user's inhalation. For example, when the aerosol generated in the aerosol generating article 3 is cooled by the external air, such liquid substances (for example, moisture, etc.) are generated. When the aerosol generating article 3 is packaged with the outer wrapping paper 35, the liquid substances generated in the aerosol generating article 3 can be prevented from leaking to the outside. In one embodiment, the wrapping paper 34, 35 may have at least one hole (hole, not shown) through which the external air flows in or the internal gas flows out to the outside.

[0113] In one embodiment, the drying section 140 can dry the extruded medium. According to one embodiment, the medium passing through the extrusion section 130 can be firmly compacted on the frame 312, but since the medium is coated on the medium coating section 120 in a slurry state, it can still remain in a wet state.
