Description

Technical Field

[0001] Embodiments relate to an aerosol-generating article and an aerosol-generating system including the same that can increase the amount of volatile flavorant transmitted to a user.

Background Art

[0002] In recent years, there has been an increasing demand for alternative methods to overcome the drawbacks of conventional cigarettes. For example, there is an increasing demand for systems that generate an aerosol by heating a cigarette (or "aerosol-generating article") using an aerosol-generating device, rather than by burning the cigarette to generate an aerosol.

[0003] The aerosol-generating article may contain a flavorant that gives the user a sense of flavor. The flavorant may be included in the aerosol passing through the aerosol-generating article and transmitted to the user.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Also, embodiments of the present disclosure provide an aerosol-generating article and an aerosol-generating system including the same that can reduce the possibility of liquid leakage of the volatile flavorant.

[0006] The problems to be solved through the embodiments of the present disclosure are not limited to the above problems, and problems not mentioned can be clearly understood by those having ordinary knowledge in the technical field to which the embodiments belong from the present specification and the accompanying drawings.

Means for Solving the Problems

[0007] An aerosol product according to one embodiment may include a tobacco rod containing an aerosol-generating substance, a cooling rod located downstream of the tobacco rod and containing a hollow structure, and a filter rod containing a volatile flavoring agent. The filter rod may include a first filter section connected upstream of the tobacco rod and a second filter section positioned between the tobacco rod and the cooling rod. The first content of the volatile flavoring agent contained in the first filter section may be greater than the second content of the volatile flavoring agent contained in the second filter section.

[Effects of the Invention]

[0009] According to various embodiments of this disclosure, the amount of volatile flavoring agents transmitted to the user can be increased, thereby improving the flavor sensation perceived by the user.

[0010] Furthermore, since the possibility of leakage of volatile flavorings can be reduced, the cleanliness and ease of use of the aerosol generation system can be improved.

[0012] [Figure 1]This is a perspective view of an aerosol product according to one embodiment. [Figure 2] This is a perspective view showing a comparative example of aerosol products. [Figure 3] This is a perspective view of an aerosol generating apparatus according to one embodiment and the aerosol product inserted therein. [Figure 4] This is a schematic front view of an aerosol generating apparatus according to one embodiment and the aerosol product inserted therein. [Modes for carrying out the invention]

[0013] The terminology used in the embodiments has been selected as widely used and general terms as possible, taking into account the function of the present invention, although this may change depending on the intent of the articulators, precedents, the emergence of new technologies, etc. In certain cases, the applicant may have arbitrarily selected terms, in which case their meaning will be described in detail in the description of the relevant invention. Therefore, the terms used in the present invention must not be merely names of terms, but must be defined based on the meaning of the terms and the overall content of the present invention.

[0014] Throughout this specification, when a part is said to "include" a component, this means, unless otherwise stated, that it may include other components rather than excluding them. Furthermore, as used herein, terms such as "part" and "module" mean a unit that performs at least one function or operation, which may be implemented in hardware or software, or in combination of hardware and software.

[0015] As used herein, when expressions such as “at least one” precede a sequence of components, they modify the entire sequence of components, rather than each individual component. For example, the expression “at least one of a, b, and c” must be interpreted as including a, b, c, or a and b, a and c, b and c, or a and b and c.

[0016] In one embodiment, the aerosol generating device may be a device that generates an aerosol by electrically heating a cigarette contained in an internal space.

[0017] The aerosol generator may include a heater. In one embodiment, the heater may be an electrical resistance heater. For example, the heater may include an electrical conductive track, and the heater may be heated when an electric current flows through the electrical conductive track.

[0018] The heater may include tubular heating elements, plate heating elements, needle-shaped heating elements, or rod-shaped heating elements, and can heat the inside or outside of the cigarette depending on the shape of the heating elements.

[0019] A cigarette may include a tobacco rod and a filter rod. The tobacco rod may be made in sheet form, strand form, or as shredded tobacco from a tobacco sheet. Furthermore, the tobacco rod may be surrounded by a heat-conducting material. For example, the heat-conducting material may be, but is not limited to, a metal foil such as aluminum foil.

[0020] The filter rod may be a cellulose acetate filter. The filter rod may consist of at least one segment. For example, the filter rod may include a first segment for cooling the aerosol and a second segment for filtering out a predetermined component contained in the aerosol.

[0021] In other embodiments, the aerosol generating apparatus may be an apparatus that generates aerosols using a cartridge that holds an aerosol generating substance.

[0022] The aerosol generating device can include a cartridge that holds the aerosol generating substance and a main body that supports the cartridge. The cartridge can be detachably coupled to the main body, but is not limited thereto. The cartridge may be integrally formed or assembled with the main body and may be fixed so as not to be detached by the user. The cartridge may be mounted on the main body with the aerosol generating substance contained therein. 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.

[0023] The cartridge can hold an aerosol generating substance having any one of various states such as a liquid state, a solid state, a gaseous state, or a gel state. The aerosol generating substance may include a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing substance including a volatile tobacco flavor component, or may be a liquid containing a non-tobacco substance.

[0024] The cartridge can perform a function of converting the phase of the aerosol generating substance inside the cartridge into a gaseous phase to generate an aerosol by operating by an electrical signal, a wireless signal, or the like transmitted from the main body. The aerosol can mean a gas in a state where vaporized particles generated from the aerosol generating substance and air are mixed.

[0025] In yet another embodiment, the aerosol generating device can heat the liquid composition to generate an aerosol, and the generated aerosol can be transmitted to the user through a cigarette. That is, the aerosol generated from the liquid composition can move along the air flow path of the aerosol generating device, and the air flow path can be configured such that the aerosol is transmitted to the user through the cigarette.

[0026] In further embodiments, the aerosol generating device may be a device that generates aerosols from an aerosol-generating substance using an ultrasonic vibration method. In this case, the ultrasonic vibration method can mean a method of generating aerosols by atomizing the aerosol-generating substance with ultrasonic vibrations generated by a transducer.

[0027] The aerosol generator includes a transducer, which generates short-period vibrations to atomize the aerosol-generating substance. The vibrations generated by the transducer may be ultrasonic vibrations, and the frequency range of the ultrasonic vibrations may be, but is not limited to, a frequency range of approximately 100 kHz to approximately 3.5 MHz.

[0028] The aerosol generator may further include a core that absorbs the aerosol-generating material. For example, the core may be positioned to surround at least one region of the oscillator, or to be in contact with at least one region of the oscillator.

[0029] When a voltage (e.g., an AC voltage) is applied to the transducer, heat and / or ultrasonic vibrations may be generated from the transducer, and these heat and / or ultrasonic vibrations can be transmitted to the aerosol-generating material absorbed in the core. The aerosol-generating material absorbed in the core is converted into a gaseous phase by the heat and / or ultrasonic vibrations transmitted from the transducer, and as a result, an aerosol may be generated.

[0030] For example, the viscosity of the aerosol-generating material absorbed into the core may decrease due to the heat generated from the transducer, and the aerosol-generating material with reduced viscosity may be atomized by the ultrasonic vibrations generated from the transducer, thereby generating an aerosol, but this is not limited to this.

[0031] In yet another embodiment, the aerosol generating apparatus may be a device that generates aerosols by heating the aerosol product contained in the aerosol generating apparatus using induction heating.

[0032] The aerosol generator may include a susceptor and a coil. In one embodiment, the coil can apply a magnetic field to the susceptor. By supplying power to the coil from the aerosol generator, a magnetic field can be formed inside the coil. In one embodiment, the susceptor may be a magnetic material that generates heat in response to an external magnetic field. The aerosol product can be heated by the heat generated when the susceptor is located inside the coil and a magnetic field is applied. Alternatively, the susceptor may be selectively located within the aerosol product.

[0033] In further embodiments, the aerosol generator may further include a cradle.

[0034] The aerosol generator can be configured as a system with a separate cradle. For example, the cradle can charge the aerosol generator's battery. Alternatively, the heater may be heated when the cradle and aerosol generator are combined.

[0035] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings, so that they can be easily implemented by a person skilled in the art. The present disclosure may be implemented in a manner that can be realized in the aerosol generating apparatus according to the various embodiments described above, or in a variety of different manners, and is not limited to the embodiments described herein.

[0036] Figure 1 is a perspective view of an aerosol product according to one embodiment.

[0037] Referring to Figure 1, the aerosol product 5 may include a tobacco rod 51, a filter rod 52, and a cooling rod 53. The filter rod 52 may include a first filter section 521, a second filter section 522, and a third filter section 523.

[0038] The tobacco rod 51, the filter rod 52, and the cooling rod 53 may be arranged along the longitudinal direction of the aerosol product 5. Specifically, the first filter section 521, the tobacco rod 51, the second filter section 522, the cooling rod 53, and the third filter section 523 may be arranged sequentially along the longitudinal direction of the aerosol product 5.

[0039] The tobacco rod 51 may contain an aerosol-generating substance. The tobacco rod 51 may contain an aerosol-generating substance containing nicotine. Furthermore, the tobacco rod 51 may contain tobacco material. The tobacco material may, but is not limited to, take the form of tobacco strand, tobacco particle, tobacco sheet, tobacco beads, tobacco granule, tobacco powder, or tobacco extract.

[0040] In one embodiment, the tobacco rod 51 may contain a plurality of tobacco granules. The tobacco granules may be particles having a diameter of about 100 μm to about 2,000 μm. The tobacco granules may be produced by extruding a mixture of crushed tobacco leaves, a pH adjuster, and a solvent.

[0041] The pH adjuster alkalizes the tobacco rod 51, thereby converting the nicotine salts present in the tobacco rod 51 in a salt state into freebase nicotine.

[0042] Freebase nicotine can refer to neutral nicotine that has not been protonated. For example, when a strong base such as ammonia is added to a positively charged nicotine salt, the strong base is converted into a cation, and the nicotine salt can become freebase nicotine, which is in a neutral state.

[0043] Nicotine exists in nature as nicotine salts such as nicotine malate and nicotine citrate, but since nicotine salts have relatively high boiling points, they must be heated to a temperature of at least 120°C in order to generate nicotine vapor.

[0044] On the other hand, freebase nicotine has a relatively lower boiling point and is more volatile than nicotine salts. Therefore, if the freebase nicotine content of the tobacco medium is high, nicotine vapor can be generated under relatively low heating conditions.

[0045] Therefore, as the hot aerosol vapor generated in the aerosol generator described later passes through the tobacco rod 51, nicotine vapor can be generated in the tobacco rod 51, which contains freebase nicotine converted from nicotine.

[0046] According to one embodiment, the tobacco rod 51 may include an empty space 51a (hollow) that contains a plurality of tobacco granules. As a result, the volatile flavoring agent contained in the first filter portion 521 can easily pass through the tobacco rod 51 having the empty space 51a, so that a large amount of flavoring agent can be transmitted to the user. In this disclosure, the empty space 51a is a space formed inside the tobacco rod 51 and is called a granule cavity.

[0047] The tobacco rod 51 can be manufactured in various ways. In one embodiment, the tobacco rod 51 may be manufactured in a form that includes a tubular structure such as a paper tube. However, the scope of this disclosure is not limited thereto, and the tobacco rod 51 may be manufactured in any way as long as it can be filled with tobacco granules.

[0048] The tobacco rod 51 may extend along its longitudinal direction to have a length of 12 mm or more and 16 mm or less. However, the length of the tobacco rod 51 is not limited thereto, and the length of the tobacco rod 51 can be appropriately adjusted within a range that can be easily changed by an ordinary technician.

[0049] The first filter section 521 can be located upstream of the tobacco rod 51 as a filter segment connected to the tobacco rod 51. The first filter section 521 can function to prevent the tobacco granules from separating from the tobacco rod 51. The first filter section 521 may also be configured to ensure that the tobacco rod 51 is positioned appropriately within the aerosol generator when the aerosol product 5 is inserted into the aerosol generator. Furthermore, the first filter section 521 can prevent the tobacco rod 51 from detaching to the outside, thereby preventing liquefied aerosol from flowing from the tobacco rod 51 into the aerosol generator during smoking.

[0050] In this disclosure, "upstream" may refer to the direction from the cooling rod 53 toward the tobacco rod 51, and "downstream" may refer to the direction from the tobacco rod 51 toward the cooling rod 53.

[0051] The first filter section 521 may be manufactured to generate flavor. In one embodiment, the first filter section 521 may contain a volatile flavoring agent, or a separate fiber containing a volatile flavoring agent may be inserted inside the first filter section 521. This allows the volatile flavoring agent contained in the first filter section 521 to be transmitted to the user when the user inhales the aerosol, passing through the tobacco rod 51, the second filter section 522, the cooling rod 53, and the third filter section 523.

[0052] In one embodiment, the volatile flavoring agent may include, but is not limited to, at least one of menthol, peppermint, spearmint oil, or a humectant.

[0053] In one embodiment, the first filter portion 521 may be a cellulose acetate filter. For example, the filter material may include bundles of cellulose acetate fiber strands.

[0054] The first filter section 521 can be manufactured from a material suitable for a heated aerosol generator. The first filter section 521 may include paper material. In other words, the first filter section 521 can consist of a paper filter. Heat-resistant paper material melts or shrinks when in contact with the internal heating element of the aerosol generator, which can greatly mitigate the phenomenon of tobacco granules falling off.

[0055] To ensure a smooth airflow path, it is sometimes desirable for paper materials to be arranged in the longitudinal direction. However, this is not the only option.

[0056] Furthermore, the first filter section 521 may contain a water-resistant or oil-resistant paper material. In this case, the problem of a decrease in visible atomization can be significantly reduced.

[0057] On the other hand, the physical properties of the paper material contained in the first filter section 521 can vary.

[0058] The first filter section 521 may extend along its longitudinal direction to have a length of 3 mm to 12 mm. However, the length of the first filter section 521 is not limited to this, and the length of the first filter section 521 can be adjusted as appropriate within a range that can be easily changed by an ordinary technician.

[0059] There are no restrictions on the shape of the first filter section 521. For example, the first filter section 521 may be a cylindrical rod, or a tubular rod containing a hollow interior. Alternatively, the first filter section 521 may be a concave rod containing a hollow end.

[0060] The second filter section 522 can be located downstream of the tobacco rod 51 as a filter segment connected to the tobacco rod 51. The second filter section 522 can function to prevent the tobacco granules from separating from the tobacco rod 51. In addition, when the aerosol product 5 is inserted into the aerosol generator, the second filter section 522 can position the tobacco rod 51 in an appropriate location within the aerosol generator. Furthermore, the second filter section 522 can prevent the tobacco rod 51 from detaching to the outside and prevent liquefied aerosol from flowing from the tobacco rod 51 into the aerosol generator during smoking.

[0061] The second filter section 522 can further perform functions such as filtration and cooling of aerosols.

[0062] The second filter section 522 may be manufactured to generate flavor. In one embodiment, the second filter section 522 may contain a volatile flavoring agent, or a separate fiber containing a volatile flavoring agent may be inserted inside the second filter section 522. This allows the volatile flavoring agent contained in the second filter section 522 to be transmitted to the user through the cooling rod 53 and the third filter section 523 when the user inhales the aerosol.

[0063] In one embodiment, the volatile flavoring agent may include, but is not limited to, at least one of menthol, peppermint, spearmint oil, or a humectant.

[0064] In one embodiment, the second filter portion 522 may be a cellulose acetate filter. For example, the filter material may include bundles of cellulose acetate fiber strands.

[0065] The second filter section 522 may be manufactured from a material suitable for a heated aerosol generator. The second filter section 522 may include paper material. In other words, the second filter section 522 can consist of a paper filter. Heat-resistant paper material melts or shrinks upon contact with the internal heating element, which can significantly mitigate the phenomenon of tobacco granules falling off.

[0066] To ensure a smooth airflow path, it is sometimes desirable for paper materials to be arranged in the longitudinal direction. However, this is not the only option.

[0067] Furthermore, the second filter section 522 may contain a water-resistant or oil-resistant paper material. In this case, the problem of a decrease in visible atomization can be significantly reduced.

[0068] On the other hand, the physical properties of the paper material contained in the second filter section 522 can vary.

[0069] The second filter section 522 may extend along its longitudinal direction to have a length of 3 mm or more and 8 mm or less. However, the length of the second filter section 522 is not limited thereto, and the length of the second filter section 522 may be adjusted as appropriate within a range that can be easily changed by an ordinary technician.

[0070] There are no restrictions on the shape of the second filter section 522. For example, the second filter section 522 may be a cylindrical rod, or a tubular rod containing a hollow interior. Alternatively, the second filter section 522 may be a concave rod containing a hollow end.

[0071] The third filter section 523 can filter out some of the components contained in the aerosol passing through it. The third filter section 523 can contain a filter material. For example, the third filter section 523 may be a cellulose acetate filter. The third filter section 523 may be manufactured by adding a plasticizer (e.g., triacetin) to cellulose acetate tow.

[0072] The third filter section 523 may be manufactured to generate flavor. In one embodiment, the third filter section 523 may contain a volatile flavoring agent, or a separate fiber containing a volatile flavoring agent may be inserted inside the third filter section 523. This allows the volatile flavoring agent contained in the third filter section 523 to be transmitted to the user when the user inhales the aerosol.

[0073] In one embodiment, the volatile flavoring agent may include, but is not limited to, at least one of menthol, peppermint, spearmint oil, or a humectant.

[0074] Furthermore, the third filter section 523 may include at least one capsule, which can generate flavor or an aerosol. For example, the capsule may have a structure in which a liquid containing a flavor is surrounded by a film. The capsule may, but is not limited to, a spherical or cylindrical shape.

[0075] The third filter section 523 may extend to have a length of 10 mm or more and 16 mm or less along its longitudinal direction. Preferably, the third filter section 523 may extend to have a length of 13 mm along its longitudinal direction. However, the length of the third filter section 523 is not limited thereto, and the length of the third filter section 523 may be adjusted as appropriate within a range that can be easily changed by an ordinary technician.

[0076] There are no restrictions on the shape of the third filter section 523. For example, the third filter section 523 may be a cylindrical rod, or a tubular rod containing a hollow interior. Alternatively, the third filter section 523 may be a concave rod containing a hollow end. If the third filter section 523 consists of multiple segments, at least one of the segments may be made in a different shape.

[0077] The cooling rod 53 can cool the aerosol generated from the tobacco rod 51. The cooling rod 53 may be made of a biodegradable polymer material and may have a cooling function. For example, the cooling rod 53 may be made of polylactic acid (PLA) fiber, but is not limited thereto.

[0078] Alternatively, the cooling rod 53 may be made from a cellulose acetate filter. However, the cooling rod 53 is not limited to the examples described above, and any material that performs the function of cooling an aerosol may be included without limitation.

[0079] The cooling rod 53 can be connected to the cigarette rod 51. In one embodiment, the cooling rod 53 can be connected to the cigarette rod 51 via a second filter section 522.

[0080] In one embodiment, the cooling rod 53 may be a tube filter containing a hollow 53a or a paper tube made of paper.

[0081] At least one hole (not shown) may be formed on the outer surface of the cooling rod 53. The at least one hole may be formed along the circumferential direction of the cooling rod 53 to form one or more columns. The at least one hole may allow outside air to flow into the inside of the cooling rod 53. The outside air that flows into the inside of the cooling rod 53 can mix with the hot aerosol generated from the tobacco rod 51 to cool the aerosol.

[0082] The cooling rod 53 may extend to have a length of 10 mm to 14 mm along its longitudinal direction. Preferably, the cooling rod 53 may extend to have a length of 12 mm along its longitudinal direction. However, the length of the cooling rod 53 is not limited thereto, and the length of the cooling rod 53 can be appropriately adjusted within a range that can be easily changed by an ordinary technician.

[0083] Although not shown, the aerosol product 5 may be packaged by at least one wrapper. The wrapper may have at least one hole through which external air flows in and internal gases flow out. For example, the aerosol product 5 may be packaged by one wrapper. As another example, the aerosol product 5 may be packaged in layers by two or more wrappers. For example, the tobacco rod 51 may be packaged by a first wrapper, the first filter section 521, the second filter section 522, and the third filter section 523 may be packaged by second to fourth wrappers, and the cooling rod 53 may be packaged by a fifth wrapper. The entire aerosol product 5 may then be repackaged by a single wrapper.

[0084] In the following, in order to improve the amount of flavoring agent transmitted to the user, the structure of the segments of the aerosol product according to one embodiment will be specifically described with reference to the attached drawings and experimental examples. First, the structure of the aerosol product according to the comparative example will be described.

[0085] Figure 2 is a perspective view showing a comparative example of aerosol products.

[0086] Referring to Figure 2, the aerosol product 7 may include a tobacco rod 71 and a filter rod 72. The filter rod 72 may also include a first filter section 721 and a second filter section 722.

[0087] The tobacco rod 71 may contain multiple tobacco granules. The tobacco granules can be produced by extruding a mixture of crushed tobacco leaves, a pH adjuster, and a solvent. The pH adjuster can alkalize the tobacco rod 71, thereby converting the nicotine salts present in the tobacco rod 71 in a salt state into freebase nicotine.

[0088] The first filter section 721 and the second filter section 722 may be positioned on either side of the tobacco rod 71. Each of the first filter section 721 and the second filter section 722 may be manufactured to generate flavor.

[0089] On the other hand, in the comparative example, the tobacco rod 71 may include a bundle of cellulose acetate fiber strands. The fiber bundle can increase the amount of nicotine transferred by positioning the freebase nicotine released from the tobacco granules onto the tobacco rod 71.

[0090] In this case, the fiber bundle of the tobacco rod 71 can filter out the volatile flavoring agent contained in the first filter section 721, thereby reducing the amount of flavoring agent transmitted to the user. In particular, if direct heating of the aerosol product 7 is not performed, the fiber bundle of the tobacco rod 71 can significantly reduce the amount of flavoring agent transmitted to the user.

[0091] According to one embodiment, the tobacco rod 51 includes an empty space 51a, and tobacco granules can be filled into the empty space 51a. As a result, the volatile flavoring agent contained in the first filter section 521 can easily pass through the tobacco rod 51 having the empty space 51a, allowing the user to inhale a large amount of flavoring agent.

[0092] Furthermore, compared to the comparative example, product 5 of the aerosol product further includes a cooling rod 53 having a hollow 53a, which can increase the amount of volatile flavoring agent transferred through the hollow 53a.

[0093] The effects described above can be demonstrated through Experiment 1, which compares the amount of volatile flavoring transferred using aerosol product 5 in the example shown in Figure 1 with the amount of volatile flavoring transferred using aerosol product 7 in the comparative example shown in Figure 2.

[0094] [Experiment 1] First, prepare aerosol product 5 according to the example, in which a predetermined amount of menthol is contained in the filter rod, and aerosol product 7 according to the comparative example.

[0095] Next, using the aerosol generating apparatus 1 shown in Figure 3 and subsequent figures, the amount of menthol transferred by the aerosol product 5 according to the example and the aerosol product 7 according to the comparative example is measured.

[0096] Next, the experiment is repeated by changing the amount of menthol contained in the filter rod, and the amount of menthol transferred is recorded.

[0097] [Table 1]

[0098] [Table 2]

[0099] [Table 3]

[0100] [Table 4]

[0101] [Table 5]

[0102] In Tables 1 to 5 above, the total menthol content per article refers to the total menthol content contained in aerosol product 5 according to the example and aerosol product 7 according to the comparative example. In other words, the total menthol content per article refers to the total menthol content contained in the filter rod 52 of aerosol product 5 according to the example and the filter rod 72 of aerosol product 7 according to the comparative example.

[0103] In Tables 1 to 5 above, the amount of menthol transferred per predetermined puff refers to the total amount of menthol transferred to the user when the user inhales the aerosol product a predetermined number of times (14 times).

[0104] Furthermore, in Tables 1 to 5, the menthol transfer rate refers to the ratio of the total menthol content in the article to the amount of menthol transferred per predetermined puff, expressed as a percentage. In other words, the menthol transfer rate in the example is the percentage obtained by dividing the amount of volatile flavoring agent that passed through the third filter section 523 by the total content of volatile flavoring agent contained in the filter rod 52, while the menthol transfer rate in the comparative example is the percentage obtained by dividing the amount of volatile flavoring agent that passed through the second filter section 722 by the total content of volatile flavoring agent contained in the filter rod 72.

[0105] Referring to Tables 1 to 5, it can be seen that even though the total menthol content in the aerosol product 7 of the comparative example is greater than the total menthol content in the aerosol product 5 of the example, the amount and rate of menthol transfer are greater in the example. This is because, as mentioned above, the volatile flavoring agent contained in the filter section 521 can easily pass through the tobacco rod 51 which has an empty space 51a and the cooling rod 53 which has a hollow space 53a.

[0106] Furthermore, by arranging the first filter section 521 and the second filter section 522 on either side of the tobacco rod 51 which has an empty space 51a, the freebase nicotine released from the tobacco granules can be positioned on the tobacco rod 51. In other words, unlike conventional designs, the tobacco rod 51 includes an empty space 51a filled with tobacco granules, so there is no configuration to position the freebase nicotine in the empty space 51a. However, since the first filter section 521 and the second filter section 522 perform this function, the amount of nicotine delivered can also be guaranteed.

[0107] In the following, various examples of the content of volatile flavorings contained in the aerosol product according to one embodiment will be specifically described with reference to experimental examples, in order to improve the amount of flavorings transmitted to the user.

[0108] According to one embodiment, the first content of the volatile flavoring agent contained in the first filter section 521 may be greater than the second content of the volatile flavoring agent contained in the second filter section 522. This makes it possible to improve the amount of menthol transferred compared to a comparative example in which the first content is smaller than the second content. This effect can be demonstrated in Experiment 2 below.

[0109] [Experiment 2] First, an aerosol product in which the content of the first component is greater than the content of the second component (Example) and an aerosol product in which the content of the first component is less than the content of the second component (Comparative Example) are prepared. In this case, the total menthol content of the Example and the Comparative Example may be the same at 12 mg / article, and the total menthol content contained in the third filter section 523 may also be the same at 2 mg.

[0110] Next, the amount of menthol transferred from the prepared aerosol product is measured using the aerosol generating apparatus 1 shown in Figure 3 and subsequent figures.

[0111] [Table 6]

[0112] In Table 6 above, the first content refers to the total menthol content contained in the first filter section 521, and the second content refers to the total menthol content contained in the second filter section 522.

[0113] In Table 6 above, the amount of menthol transferred per predetermined puff refers to the total amount of menthol transferred to the user when the user inhales the aerosol product a predetermined number of times (14 times).

[0114] Furthermore, in Table 6, the menthol transfer rate refers to the ratio of the total menthol content in the article to the amount of menthol transferred per predetermined puff, expressed as a percentage. In other words, the menthol transfer rate is the percentage obtained by dividing the amount of volatile flavoring agent that passed through the third filter section 523 by the total volatile flavoring agent content in the filter rod 52.

[0115] Referring to Table 6 above, it can be seen that, even though the comparative example and the example contain the same amount of menthol in the filter rod 52, the example in which the first content is greater than the second content shows a greater menthol transfer rate. In other words, the more volatile flavoring agent is included upstream of the tobacco rod 51, the greater the amount of menthol that passes through the third filter section 523 may be.

[0116] Generally, volatile flavorings contained in areas far from the part that the user's mouth comes into contact with tend to evaporate before reaching the user compared to volatile flavorings contained in areas closer to the part that the user's mouth comes into contact with. Therefore, according to one embodiment, by including a large amount of volatile flavoring upstream of the tobacco rod 51, which is an area far from the part that the user's mouth comes into contact with, the overall transfer rate of volatile flavorings can be increased.

[0117] In one embodiment, the volume of the first filter section 521 may be larger than the volume of the second filter section 522. This allows the first filter section 521 to contain a larger amount of volatile flavoring agent.

[0118] According to one embodiment, the second content of the volatile flavoring agent contained in the second filter section 522 may be greater than the third content of the volatile flavoring agent contained in the third filter section 523. This makes it possible to improve the amount of menthol transferred compared to a comparative example in which the second content is smaller than the third content. This effect can be demonstrated in Experiment 3 below.

[0119] [Experiment 3] First, an aerosol product in which the content of the second substance is greater than the content of the third substance (Example) and an aerosol product in which the content of the second substance is less than the content of the third substance (Comparative Example) are prepared. In this case, the total menthol content of the Example and the Comparative Example may be the same at 12 mg / article, and the total menthol content contained in the first filter section 521 may also be the same at 6 mg.

[0120] Next, the amount of menthol transferred from the prepared aerosol product is measured using the aerosol generating apparatus 1 shown in Figure 3 and subsequent figures.

[0121] [Table 7]

[0122] In Table 7 above, the second content refers to the total menthol content contained in the second filter section 522, and the third content refers to the total menthol content contained in the third filter section 523.

[0123] In Table 7 above, the amount of menthol transferred per predetermined puff refers to the total amount of menthol transferred to the user when the user inhales the aerosol product a predetermined number of times (14 times).

[0124] Furthermore, in Table 7, the menthol transfer rate refers to the ratio of the total menthol content in the article to the amount of menthol transferred per predetermined puff, expressed as a percentage. In other words, the menthol transfer rate is the percentage obtained by dividing the amount of volatile flavoring agent that passed through the third filter section 523 by the total volatile flavoring agent content in the filter rod 52.

[0125] Referring to Table 7 above, it can be seen that, even though the comparative example and the example contain the same amount of menthol in the filter rod 52, the example in which the second content is greater than the third content shows a higher menthol transfer rate. In other words, the more volatile flavoring agent is included upstream of the cooling rod 53, the greater the amount of menthol that passes through the third filter section 523 may be.

[0126] Furthermore, comparing the comparative examples in Table 7 and Table 6, it can be seen that the more volatile flavoring agent is present upstream of the tobacco rod 51, the greater the amount of menthol that passes through the third filter section 523.

[0127] Generally, volatile flavorings contained in areas far from the user's mouth tend to volatilize before reaching the user compared to volatile flavorings contained in areas closer to the user's mouth. Therefore, according to one embodiment, by including a large amount of volatile flavoring upstream of the cooling rod 53, which is an area far from the user's mouth, the overall transfer rate of volatile flavorings can be increased.

[0128] According to one embodiment, the total content of volatile flavoring agents contained in the filter rod 52 may be between 11.1 mg and 13.0 mg. In this case, the total content of volatile flavoring agents contained in the filter rod 52 can be between 1.3 mg / mm and 1.52 mg / mm, based on the length of the filter rod 52. For example, the total content of volatile flavoring agents contained in the filter rod 52 may be 10 mg or 1.4 mg / mm.

[0129] In one embodiment, the first content may be in the range of 5.7 mg or more and 6.5 mg or less. In this case, the first content may be in the range of 0.55 mg / mm or more and 0.65 mg / mm or less, based on the length of the first filter portion 521. For example, the first content may be 6.0 mg or 0.60 mg / mm.

[0130] Within this first content range, the transfer rate of the volatile flavoring agent contained in the first filter section 521 increases, improving the flavor and reducing the likelihood of leakage of the volatile flavoring agent contained in the first filter section 521. This can be demonstrated by Experiment 4 below.

[0131] [Experiment 4] First, an aerosol product 5 is prepared, having a first filter section 521 containing different menthol content.

[0132] Next, the aerosol product 5 is changed, and the menthol transfer rate, flavor, and whether or not leakage occurred from the first filter section 521 are recorded using the aerosol generating device 1 shown in Figure 3 and subsequent figures.

[0133] At this time, the menthol content in the second filter section 522 and the third filter section 523 is maintained at 4 mg and 2 mg, respectively.

[0134] [Table 8]

[0135] In Table 8, the first content refers to the total menthol content contained in the first filter section 521. Also in Table 8, the amount of menthol transferred per predetermined puff refers to the total amount of menthol transferred to the user when the user inhales the aerosol product a predetermined number of times (14 times). Also in Table 8, the menthol transfer rate refers to the ratio of the total menthol content contained in the product to the amount of menthol transferred per predetermined puff, expressed as a percentage. In other words, the menthol transfer rate is the value obtained by dividing the amount of volatile flavoring agent that passed through the third filter section 523 by the total content of volatile flavoring agent contained in the filter rod 52, expressed as a percentage.

[0136] Referring to Table 8 above, it can be seen that the menthol transfer rate gradually increases as the first content increases. In one example, when the first content is 5.7 mg or more, it can be seen that as the amount of menthol transferred per predetermined puff increases rapidly from 0.92 mg to 1.51 mg, the menthol transfer rate increases rapidly from 7.9% to 12.9%.

[0137] Furthermore, referring to Table 8, it can be seen that the flavor sensation perceived by the user improves as the content of the first element increases up to 6.5 mg. However, it can be seen that when the content of the first element exceeds 6.5 mg, the flavor sensation perceived by the user actually decreases. This is because when the first filter section 521 contains more menthol than the preset amount, the highly concentrated volatile flavoring agent is immediately transmitted to the user, resulting in a decrease in flavor sensation.

[0138] Furthermore, referring to Table 8 above, it can be seen that if the first content exceeds 6.5 mg, leakage will occur in the first filter section 521. This is because if the first filter section 521 contains more menthol than the preset amount, the menthol solution will not be completely absorbed by the fibers of the first filter section 521.

[0139] According to one embodiment, by setting the first content to a range of 5.7 mg to 6.5 mg, the amount of volatile flavoring agent transferred increases while improving the flavor, and the possibility of leakage of volatile flavoring agent in the first filter section 521 can be reduced.

[0140] In one embodiment, the second content may be in the range of 3.7 mg to 4.3 mg. In this case, the second content may be in the range of 0.62 mg / mm to 0.70 mg / mm, based on the length of the second filter portion 522. For example, the second content may be 4.0 mg or 0.65 mg / mm.

[0141] Within this second content range, the transfer rate of the volatile flavoring agent contained in the second filter section 522 increases, improving the flavor and reducing the likelihood of leakage of the volatile flavoring agent contained in the second filter section 522. This can be demonstrated by Experiment 5 below.

[0142] [Experiment 5] First, an aerosol product 5 is prepared, having a second filter section 522 containing different menthol content.

[0143] Next, the aerosol product 5 is changed, and the menthol transfer rate, flavor, and whether or not leakage occurred from the second filter section 522 are recorded using the aerosol generating device 1 shown in Figure 3 and subsequent figures.

[0144] At this time, the menthol content in the first filter section 521 and the third filter section 523 is maintained at 6 mg and 2 mg, respectively.

[0145] [Table 9]

[0146] In Table 9, the second content refers to the total menthol content contained in the second filter section 522. Also in Table 9, the amount of menthol transferred per predetermined puff refers to the total amount of menthol transferred to the user when the user inhales the aerosol product a predetermined number of times (14 times). Also in Table 9, the menthol transfer rate refers to the ratio of the total menthol content contained in the product to the amount of menthol transferred per predetermined puff, expressed as a percentage. In other words, the menthol transfer rate is the value obtained by dividing the amount of volatile flavoring agent that passed through the third filter section 523 by the total content of volatile flavoring agent contained in the filter rod 52, expressed as a percentage.

[0147] Referring to Table 9 above, it can be seen that the menthol transfer rate gradually increases as the content of the second substance increases. In one example, when the content of the second substance is 3.7 mg or more, it can be seen that as the amount of menthol transferred per given puff increases rapidly from 0.92 mg to 1.51 mg, the menthol transfer rate increases rapidly from 7.9% to 12.9%.

[0148] Furthermore, referring to Table 9 above, it can be seen that the flavor sensation perceived by the user improves as the content of the second substance increases up to 4.3 mg. However, it can be seen that when the content of the second substance exceeds 4.3 mg, the flavor sensation perceived by the user actually decreases. This is because when the second filter section 522 contains more menthol than the preset amount, a highly concentrated volatile flavoring agent is transmitted to the user.

[0149] Furthermore, referring to Table 9 above, it can be seen that if the second content exceeds 4.3 mg, leakage will occur in the second filter section 522. This is because if the second filter section 522 contains more menthol than the preset amount, the menthol solution will not be completely absorbed by the fibers of the second filter section 522.

[0150] According to one embodiment, by setting the second content to a range of 3.7 mg to 4.3 mg, the amount of volatile flavoring agent transferred increases while improving the flavor, and the possibility of leakage of volatile flavoring agent in the second filter section 522 can be reduced.

[0151] In one embodiment, the third content may be in the range of 1.7 mg to 2.3 mg. In this case, the third content may be in the range of 0.13 mg / mm to 0.17 mg / mm, based on the length of the third filter portion 523. Preferably, the third content may be 2.0 mg or 0.15 mg / mm.

[0152] Within this third content range, the transfer rate of the volatile flavoring agent contained in the third filter section 523 increases, improving the flavor and reducing the likelihood of leakage of the volatile flavoring agent contained in the third filter section 523. This can be demonstrated by Experiment 6 below.

[0153] [Experiment 6] First, an aerosol product 5 is prepared, having a third filter section 523 containing different menthol content.

[0154] Next, the aerosol product 5 is changed, and the menthol transfer rate, flavor, and whether or not leakage occurred from the third filter section 523 are recorded using the aerosol generating device 1 shown in Figure 3 and subsequent figures.

[0155] At this time, the menthol content in the first filter section 521 and the second filter section 522 are maintained at 6 mg and 4 mg, respectively.

[0156] [Table 10]

[0157] In Table 10, the third content refers to the total menthol content contained in the third filter section 523. Also in Table 10, the amount of menthol transferred per predetermined puff refers to the total amount of menthol transferred to the user when the user inhales the aerosol product a predetermined number of times (14 times). Also in Table 10, the menthol transfer rate refers to the ratio of the total menthol content contained in the product to the amount of menthol transferred per predetermined puff, expressed as a percentage. In other words, the menthol transfer rate is the value obtained by dividing the amount of volatile flavoring agent that passed through the third filter section 523 by the total content of volatile flavoring agent contained in the filter rod 52, expressed as a percentage.

[0158] Referring to Table 10 above, it can be seen that the menthol transfer rate gradually increases as the content of the third substance increases. In one example, when the content of the third substance is 1.7 mg or more, it can be seen that as the amount of menthol transferred per given puff increases rapidly from 0.92 mg to 1.51 mg, the menthol transfer rate increases rapidly from 7.9% to 12.9%.

[0159] Furthermore, referring to Table 10, it can be seen that the flavor perceived by the user improves as the content of the third substance increases up to 2.3 mg. However, it can be seen that when the content of the third substance exceeds 2.3 mg, the flavor perceived by the user actually decreases. This is because when the third filter section 523 contains more menthol than the preset amount, a highly concentrated volatile flavoring agent is transmitted to the user.

[0160] Furthermore, referring to Table 10 above, it can be seen that if the content of the third element exceeds 2.3 mg, leakage will occur in the third filter section 523. This is because, if the third filter section 523 contains more menthol than the preset amount, the menthol solution will not be completely absorbed by the fibers of the third filter section 523.

[0161] According to one embodiment, by setting the third content to a range of 1.7 mg to 2.3 mg, the amount of volatile flavoring agent transferred increases while improving the flavor sensation, and the possibility of leakage of volatile flavoring agent in the third filter section 523 can be reduced.

[0162] In the following section, an aerosol generating apparatus using the aerosol product 5 according to the above-described embodiment will be described in detail with reference to the attached drawings.

[0163] Figure 3 is a perspective view of an aerosol generating apparatus according to one embodiment and the aerosol product inserted therein.

[0164] Referring to Figure 3, the aerosol generator 1 according to one embodiment may include a cartridge 100, an aerosol generator body 200, and a cap 300. In the aerosol generator 1 according to one embodiment, it goes without saying that some components and structures may be replaced, added, or omitted to the extent that a person skilled in the art can easily understand by referring to the following drawings and description.

[0165] Aerosol-generating material is stored inside cartridge 100, and the aerosol-generating material stored in cartridge 100 can be supplied to a heating unit contained within cartridge 100. This allows the aerosol-generating material to be aerosolized by the heating unit within the chamber contained in cartridge 100. In this disclosure, "aerosol" may mean particles produced by mixing vapor generated by heating the aerosol-generating material with air. This expression may also be used with the same meaning hereafter. A specific description of the heating unit and chamber will follow later.

[0166] According to one embodiment of the aerosol generator 1, the cartridge 100 can contain the aerosol product 5 according to one embodiment. Although not shown in Figure 3, the cartridge 100 may include a containment section for containing the aerosol product 5, and the aerosol generated inside the cartridge 100 can pass through the aerosol product 5 contained in the containment section and be discharged to the outside of the aerosol generator 1. At this time, the user can bring their mouth into contact with the aerosol product 5 and inhale the aerosol discharged to the outside of the aerosol generator 1 through the aerosol product 5. Since the aerosol product 5 according to one embodiment has been described above, a detailed explanation will be omitted.

[0167] The aerosol generator body 200 is located below the cartridge 100 and cap 300 (for example, in the -z direction) and can support the cartridge 100 and cap 300. Components for the operation of the aerosol generator 1 may be arranged inside the aerosol generator body 200.

[0168] The cap 300 may be positioned to surround at least a portion of the cartridge 100 and at least a portion of the aerosol generator body 200. For example, the cap 300 may be coupled to the aerosol generator body 200 so as to completely surround the outside of the cartridge 100. The cap 300 can protect the cartridge 100 and the aerosol generator body 200 from external impacts or the ingress of external foreign matter.

[0169] Figure 4 is a schematic front view of an aerosol generating apparatus according to one embodiment and the aerosol product inserted therein.

[0170] Referring to Figure 4, the aerosol generator 1 may include a cartridge 100, an aerosol generator body 200, and an airflow passage 400. However, the components of the aerosol generator 1 are not limited to these, and depending on the embodiment, at least one component may be added or at least one component (for example, the cap 300 in Figure 3) may be omitted.

[0171] The cartridge 100 can be detachably coupled to the aerosol generator body 200. The cartridge 100 may include a storage section 110, a housing section 120, and a chamber 130.

[0172] Aerosol-generating material can be stored in the storage section 110. The storage section 110 may be connected or fluid-connected to the internal space of the chamber 130 of the cartridge 100, so that the aerosol-generating material stored in the storage section 110 can flow into the internal space of the chamber 130 of the cartridge 100.

[0173] At this time, the aerosol-generating substance stored in the storage unit 110 may include a tobacco-containing substance containing volatile tobacco flavor components, or a liquid composition containing non-tobacco substances.

[0174] According to one embodiment, the liquid composition may contain any of the following components, or mixtures thereof: water, solvent, ethanol, plant extract, fragrance, flavoring agent, and vitamin mixture. The fragrance may include, but is not limited to, menthol, peppermint, spearmint oil, and various fruit fragrance components. The flavoring agent may contain components that can provide the user with a variety of flavors or aromas. The vitamin mixture may be, but is not limited to, a mixture of at least one of vitamins A, B, C, and E. The liquid composition may also contain aerosol-forming agents such as glycerin and propylene glycol.

[0175] For example, the liquid composition may contain a glycerin and propylene glycol solution in any weight ratio to which a nicotine salt has been added. The liquid composition may contain two or more nicotine salts. The nicotine salt can be formed by adding a suitable acid, including an organic or inorganic acid, to nicotine. The nicotine may be natural or synthetic nicotine and may have any suitable weight concentration relative to the total solution weight of the liquid composition.

[0176] The acid used to form the nicotine salt can be appropriately selected considering the rate of nicotine absorption in the blood, the operating temperature of the aerosol generator 1, the flavor or aroma, solubility, etc. For example, the acid used to form the nicotine salt may 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 these groups.

[0177] If the aerosol-generating material stored in the storage unit 110 is depleted, the user can extend their smoking time by replacing the existing cartridge 100 with a new one. As another example, if the performance of a component of the cartridge 100 (e.g., the heating element or the sealing element) deteriorates and a sufficient amount of aerosol is not generated, or if leakage of the aerosol-generating material occurs, the user can replace the existing cartridge 100 with a new one to ensure a sufficient amount of aerosol is generated or to prevent leakage of the aerosol-generating material.

[0178] In one embodiment, the aerosol generating device 1 allows for the replacement of the cartridge 100 through a structure in which the cartridge 100 is detachably coupled to the aerosol generating device body 200. That is, the aerosol generating device 1 in one embodiment may have a structure in which both the storage section 110 for storing aerosol generating material and the storage section 120 for housing aerosol generating article 5 are replaced by replacing the cartridge 100.

[0179] The containment section 120 can contain the aerosol product 5. The internal space of the containment section 120 can be spatially separated from the storage section 110, and the aerosol-generating material stored in the storage section 110 can be prevented from flowing into the internal space of the receiving section 120.

[0180] Chamber 130 can provide a space in which aerosols are generated. Chamber 130 can communicate with storage section 110 and containment section 120, respectively. A heating section may be located inside chamber 130. For example, the heating section may include a wick into which aerosol-generating material is absorbed, and a heating coil for heating the wick. However, the components of the heating section are not limited to these.

[0181] Components for the operation of the aerosol generator 1 may be arranged inside the aerosol generator body 200. For example, a battery 210 and a processor 220 may be arranged inside the aerosol generator body 200. However, the battery 210 and processor 220 are merely examples of components that may be arranged inside the aerosol generator body 200, and other components (e.g., user interface, sensors, etc.) may be further arranged inside the aerosol generator body 200 in addition to the components described above.

[0182] The battery 210 can supply power used to operate the aerosol generator 1. For example, the battery 210 can be electrically connected to the heating element of the cartridge 100 and supply power to heat the heating element. As another example, the battery 210 can supply power necessary for the operation of other components of the aerosol generator 1 (e.g., a processor).

[0183] The processor 220 can control the overall operation of the aerosol generator 1. The processor 220 may be implemented as an array of logic gates, or as a combination of a general-purpose microprocessor and memory storing a program that can be executed by this microprocessor, but is not limited to these.

[0184] According to one embodiment, the processor 220 can control the power supplied from the battery 210 to the heating section of the aerosol generator 1. For example, the processor 220 can control the amount of power supplied by the battery 210 to the heating section and the duration of power supply so that the heating section is heated to a predetermined temperature or maintained at a specified temperature.

[0185] The airflow passage 400 may be a path through which air and / or aerosols travel. The airflow passage 400 may include an inlet into which outside air flows and an outlet through which air and / or aerosols are discharged. The airflow passage 400 can connect the outside of the aerosol generator 1 with the containment section 120.

[0186] As an example, the airflow passage 400 may be formed inside the cartridge 100. In this case, the airflow passage 400 may include a first portion extending along the extension direction of the cartridge 100 and a second portion crossing the first portion. The first portion can connect the outside of the aerosol generator 1 to the chamber 130, and the second portion can connect the chamber 130 to the housing 120.

[0187] As another example, the airflow passage 400 may be formed between the cartridge 100 and the aerosol generator body 200. In this case, the airflow passage 400 may extend in a direction that crosses the extension direction of the cartridge 100.

[0188] According to one embodiment, the aerosol generated inside the cartridge 100 passes through the containment section 120 along with the outside air flowing in through the airflow passage 400, thereby transferring the freebase nicotine present in the aerosol product 5. In other words, even without a separate heating operation of the aerosol product 5, the freebase nicotine present in the aerosol product 5 can be easily transmitted to the user by the airflow inside the aerosol generator 1.

[0189] In one embodiment, the aerosol generator 1 may further include a heater 500.

[0190] The heater 500 can heat the aerosol product 5 contained in the containment section 120. At this time, the fluidity of nicotine and / or flavoring agents passing through the aerosol product 5 can be increased by the heat generated by the heater 500. This can improve at least one of the transfer amount, transfer efficiency, or transfer rate of nicotine and / or flavoring agents. Therefore, the amount of nicotine and / or flavoring agents delivered to the user can be increased.

[0191] The heater 500 may be positioned to surround the aerosol product 5 contained in the housing 120. For this purpose, the heater 500 may include a hollow cylindrical shape. However, the shape of the heater 500 is not limited thereto. For example, the heater 500 may include a tubular heating element, a plate heating element, a needle-shaped heating element, or a rod-shaped heating element. In this case, the heater 500 may extend upward on the housing 120.
