The smoking article includes: a medium section; a front filter section disposed on one side of the medium section and including a lyocell tow containing a plurality of lyocell fibers; and a mouthpiece section disposed on the opposite side of the medium section.

Description

Technical Field

[0001] This invention relates to a smoking article in which, by making the front-end filter section located upstream of and connected to the medium section consist of a tow of lyocell fibers, liquefied aerosols during smoking are prevented from flowing from the medium section into the aerosol generating device, the tow is prevented from melting due to the heat used to heat the medium section, and the uniformity of humectant dispersion within the front-end filter section is improved. Background Technology

[0002] In smoking products, the migration of tobacco components (such as nicotine and tar) and the generation of vapor have a significant impact on the user's smoking experience. Typically, smoking products use devices to heat the cigarette to a high temperature of approximately 150°C to 300°C, and the heat is transferred to the medium. As the temperature of the medium rises, tobacco components such as nicotine migrate smoothly. Alternatively, a separate heating rod can be inserted into the medium to further increase its temperature.

[0003] However, this structure has the following problems.

[0004] First, as the heating rod is heated to high temperatures, residues (sap, contaminants) from tobacco components adhere to it. These residues can cause performance degradation during device use and require regular cleaning to remove the contaminants.

[0005] Secondly, during the process of separating the tobacco product from the device after smoking, some tobacco components may enter the device, causing inconvenience to the user. These infiltrated components may reduce the device's operational performance and hygiene, negatively impacting the user experience. Summary of the Invention

[0006] Technical issues The problem to be solved by the present invention is to provide a smoking article comprising a front filter section, a medium section, a support structure, a cooling structure, and a mouthpiece section. The front filter section, which is located upstream of and connected to the medium section, is composed of a tow of lyocell fibers containing multiple lyocell fibers. This prevents liquefied aerosols from flowing from the medium section into the aerosol generating device during smoking, prevents the tow of fibers from melting due to the heat used to heat the medium section, and improves the dispersion of the humectant in the front filter section.

[0051] In this specification, the hardness of the filter tip is a quantified value representing the degree to which the diameter of the filter tip is maintained when a horizontal force is applied to the filter tip in a direction perpendicular to its length. It can be a percentage of the diameter of the filter tip after the application of the force, relative to the diameter before the force was applied. For example, the hardness (%) of the filter tip can be calculated using the following formula: (Da) / D × 100%, where D is the diameter of the filter tip and a is the distance the filter tip descends (i.e., is pressed down) under the action of a 300g weight. Measurements required to calculate the above hardness can be obtained using, for example, Filtrona's DHT 200. TM Obtained. When measuring hardness, the force applied to the filter tip can be considered equivalent to the force applied by the user when actually holding the smoking product.

[0052] In this specification, the “total fineness” of a lyocell tow or cellulose acetate tow refers to the fineness of the multi-strand filaments of the lyocell or cellulose acetate fibers that make up the lyocell tow or cellulose acetate tow.

[0053] According to one aspect of the invention, the filter of a smoking article can capture at least a portion of the smoke components generated during smoking using the smoking article. In some embodiments, the filter of the smoking article can capture at least a portion of particulate matter (total particulate matter, hereinafter referred to as "TPM") including at least one of nicotine (hereinafter referred to as "Nic"), tar (hereinafter referred to as "PG"), and glycerin (hereinafter referred to as "Gly") contained in the smoke components generated when smoking the smoking article.

[0054] In this specification, "roundness" refers to the degree of deviation from a geometric circle. For example, the roundness of a filter tip can be defined as follows: when drawing two imaginary circles with different radii that are connected to at least one point on the outer periphery of the filter tip and have the smallest distance between them, the formula is (radius of the smaller circle / radius of the larger circle) × 100%.

For example, suction resistance can be measured using the method specified in ISO standard 6565:2015. According to ISO standard 6565:2015, suction resistance can be defined as the static pressure difference between the two ends of the sample when airflow passes through it under normal conditions (22±2℃, relative humidity 60±5%), with a volumetric flow rate of 17.5 mm / s at the outlet end.

[0056] In this specification, organic acid is a term used to refer to organic compounds that are acidic.

[0057] In some embodiments, room temperature may refer to 20°C to 25°C.

[0058] In this specification, unless a separate physical quantity is expressed, the percentage of a component and the proportion of a component represent the weight percentage and the weight proportion of the component, respectively.

[0059] In this specification, "puff" can refer to the act of inhaling or introducing air through a smoking article used to generate and inhale smoke or vapor. "Number of puffs" can refer to the total number of inhalation or introduction actions during the use of the smoking article.

[0060] In this specification, HC (Health Canada) conditions can be defined as a puff volume of 55 mL, a puff frequency of once every 30 seconds, and a puff duration of 2 seconds. Specifically, HC conditions can also refer to the state of the perforated portion of the sealed filter tip. When measuring under HC conditions, the number of puffs can be up to 9.

[0061] In this specification, the "ventilation rate" (hereinafter referred to as "ventilation rate") of a smoking product can be defined as: the percentage ratio of the total volumetric flow rate (e.g., ml / s) of air entering the unburned or unheated smoking product without passing through the front end region (i.e., the upstream end in the length direction) to the total volumetric flow rate (e.g., ml / s) of air entering the outlet region (i.e., the downstream end in the length direction) of the smoking product. For example, the ventilation rate can be measured according to ISO 9512:2019. For example, the total volumetric flow rate of air entering the unburned or unheated smoking product without passing through the front end region can be the total volumetric flow rate of air entering along a direction perpendicular to the length of the smoking product. For example, the total volumetric flow rate of air entering the unburned or unheated smoking product without passing through the front end region can be the total volumetric flow rate of air entering the smoking product through the cigarette paper.

[0062] The content of total particulate matter (TPM) in the captured flue gas can be analyzed by gas chromatography-mass spectrometry (GC / MS). For example, for tar or nicotine, Cambridge filter pads (CFPs) used to capture the flue gas components can be soaked in isopropyl alcohol (IPA) for a period of time (e.g., 20 minutes to 16 hours), while for PG (propylene glycol) and Gly (glycerol), Cambridge filter pads (CFPs) used to capture the flue gas components can be soaked in methanol for a period of time (e.g., 2 hours to 16 hours). After processing with a shaking device and removing impurities through a polytetrafluoroethylene (PTFE) syringe filter, the content of total particulate matter (TPM) in the captured flue gas can be measured using a GC / MS instrument. In particular, soaking time can be more than 20 minutes for tar or nicotine, and more than 2 hours for PG and Gly.

[0063] The amount of components (especially nicotine) remaining inside the front-end filter section (especially the Lyocell filter tip and / or Lyocell tow, especially the front-end filter section) and / or segment after smoking can be measured by immersing the filter tip and / or segment (especially the front-end filter section) in water (distilled water) after smoking to extract the residual components (especially nicotine), and then analyzing them using a GC / MS instrument. In this case, the filter tip and / or segment (especially the front-end filter section) are immersed in a container of distilled water overnight (e.g., 12 to 16 hours), and the resulting solution containing the extracted components can then be used for GC / MS analysis. In particular, the immersion time can be 16 hours.

[0064] The aforementioned GC / MS equipment can be, for example, a measurement device from Agilent Technologies.

[0065] In the following, various embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0066] Figure 1 The diagram is provided for illustrative purposes only and represents an embodiment of a smoking article according to the present invention. Figure 2 A diagram illustrating a smoking article according to another embodiment of the present invention is provided for illustrative purposes.

[0067] Reference Figure 1The smoking article 100 may include a media section 110, a mouthpiece section 140, and a front filter section 111. In some embodiments, the smoking article 100 may further include at least one of a support structure 120, a cooling structure 130, and a wrapping paper 150. In some embodiments, the smoking article 100 may further include a support structure 120 and a cooling structure 130. The cooling structure 130 may be arranged downstream of the media section 110 (or on the other side, where the other side means the opposite side of one side) and spaced apart from the media section 110. The support structure 120 may be arranged between the media section 110 and the cooling structure 130. In particular, the smoking article 100 may include a media section 110, a front filter section 111, and a mouthpiece section 140, wherein the front filter section 111 is arranged upstream (or on one side) of the media section 110 and is in contact with the media section 110, and the mouthpiece section 140 is arranged on one side (i.e., downstream) of the support structure 120 across the cooling structure 130. That is, the smoking article 100 may include a media section 110, a front filter section 111, and a mouthpiece section 140. The front filter section 111 is arranged upstream (or to one side) of the media section 110 and is in contact with the media section 110. The mouthpiece section 140 is arranged in the opposite direction to the support structure 120 with reference to the cooling structure 130. In some embodiments, the smoking article 100 may include a wrapping paper 150 covering at least a portion of the media section 110, the support structure 120, the cooling structure 130, the mouthpiece section 140, and the front filter section 111. In some embodiments, the front filter section 111, the media section 110, and the mouthpiece section 140 may be arranged sequentially along the length direction of the smoking article 100. In some embodiments, the front filter section 111, the media section 110, the cooling structure 130, and the mouthpiece section 140 may be arranged sequentially along the length direction of the smoking article 100. In some embodiments, the smoking article 100 may have a front filter section 111, a medium section 110, a support structure 120, a cooling structure 130 and a mouthpiece section 140 arranged sequentially along the length of the smoking article 100.

[0068] The medium portion 110 may include an aerosol forming substrate. The medium portion 110 may include an aerosol forming substrate, thereby generating an aerosol by heating. The length of the medium portion 110 may be from about 5 mm to 14 mm (e.g., 7 mm or 12 mm), but is not limited thereto. The medium portion 110 can generate an aerosol by being inserted into an aerosol generating device and heated, and the generated aerosol (e.g., mainstream smoke) can be inhaled through the user's mouth.

[0069] In some embodiments, the aerosol forming substrate may include tobacco material, but the processing form of the tobacco material may vary. For example, the aerosol forming substrate may include reconstituted tobacco sheets, such as reconstituted tobacco sheets. In some embodiments, the aerosol forming substrate may include reconstituted tobacco sheets. In some embodiments, the aerosol forming substrate may also include a plurality of tobacco shreds (or "a plurality of tobacco shreds") finely chopped from reconstituted tobacco sheets. In some embodiments, the medium portion 110 may be filled with a plurality of tobacco shreds arranged in the same direction (e.g., parallel) and / or randomly arranged. In some embodiments, the aerosol forming substrate may include tobacco leaf shreds.

[0070] In some embodiments, the aerosol forming substrate may include reconstituted tobacco leaves and / or shredded tobacco leaves.

[0071] In some embodiments, the aerosol forming substrate or medium portion 110 may include at least one humectant. The humectant may include glycerin and / or propylene glycol, etc. However, it is not limited thereto.

[0072] In some embodiments, the aerosol forming substrate or medium portion 110 may contain other additives such as at least one flavoring agent (or what may be referred to as a "flavoring substance") and / or organic acid. For example, the flavoring agent may include licorice, sucrose, fructose syrup, artificial sweeteners (e.g., Isosweet). TM (Ingredients include) cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, peppermint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, sage, spearmint, ginger, coriander, and / or coffee, etc. However, it is not limited to these.

[0073] The front-end filter section 111 can be located upstream (on one side) of the medium section 110, and the downstream of the front-end filter section 111 can be connected to the upstream of the medium section 110. The front-end filter section 111 can prevent the medium section 110 from detaching from the outside of the smoking article 100. It can also prevent liquefied aerosols during smoking from flowing from the medium section 110 into the aerosol generating device. Figures 5 to 7 (Referring to the reference numeral '1000' in the accompanying drawings). In some embodiments, the length of the front-end filter section 111 may be from 3 mm to 12 mm (e.g., 5 mm or 10 mm), but is not limited thereto.

[0074] In one embodiment, the front-end filter section 111 may include a tow of Lyocell fibers comprising a plurality of Lyocell fibers or may be composed of a tow of Lyocell fibers.

[0075] In this invention, the lyocell fiber included in the front-end filter section 111 is an environmentally friendly fiber made from cellulose extracted from wood pulp. The aforementioned lyocell bundle can refer to a bundle formed by the cross-connection of adjacent lyocell fibers.

[0076] In some embodiments, lyocell fibers may have a Y-shaped cross section including three protrusions branching from the center, a cross-shaped cross section including four protrusions, and / or a star-shaped cross section including five or more protrusions, or an O-shaped cross section, but the invention is not limited thereto.

[0077] By incorporating lyocell material into the front-end filter section 111 according to the invention, the front-end filter section 111 does not deform even when heated to apply high heat for smoking, based on the heat-resistant properties of lyocell material, compared to a front-end filter section 111 made of cellulose acetate. That is, since the front-end filter section 111 comprises or is composed of lyocell filaments that do not melt at high temperatures, the high heat resistance of the lyocell filaments minimizes structural deformation of the front-end filter section 111, even when a heating rod is inserted into the front-end filter section 111 and heat is applied for heating, and / or when an external heater applies heat to the front-end filter section 111 arranged adjacent to the medium section 110. Therefore, the smoke composition can also remain substantially uniform throughout the smoking process, providing the user with a superior smoking experience.

[0078] Furthermore, the front-end filter section 111 according to the present invention comprises or is made of lyocell material, thus, unlike a paper filter tip having a fiber orientation, it differs from a front-end filter section 111 made of paper material due to the characteristics of the randomly arranged multiple lyocell fibers, when a heating rod for heating is inserted ( Figure 5 When the figure is labeled "1300" in the attached diagram, the heating rod can be inserted more easily.

[0079] In some embodiments, the front-end filter section 111 may further include one or more humectants dispersed in the aforementioned lyocell filament bundle. The humectant may be uniformly dispersed throughout the entire area of ​​the aforementioned lyocell filament bundle. The humectant may include glycerin and / or propylene glycol, etc. However, it is not limited thereto.

[0080] The support structure 120 can be located downstream of the medium section 110 (i.e., on the opposite side of one side), and the upstream of the support structure 120 can be connected to the downstream of the medium section 110. The support structure 120 can serve as a support member for the medium section 110. For example, when the heating element of the aerosol generating device is inserted into and / or aligned with the outside of the medium section 110, the support structure 120 can prevent the medium section 110 from moving downstream. The support structure 120 can also serve as a channel for aerosols (e.g., mainstream flue gas) formed in the medium section 110.

[0081] In some embodiments, the support structure 120 may include a tubular structure with an internal cavity 120H, and the cavity 120H may serve as a channel for aerosol movement. The cavity 120H may extend along the length direction of the support structure 120. The cavity 120H may be located at the center of a cross-section perpendicular to the length direction of the support structure 120 and extend along the length direction of the support structure 120. The cavity 120H and the support structure 120 may be coaxial along the length direction. The length of the support structure 120 may be approximately 8 mm to 14 mm (e.g., 10 mm or 12 mm), but is not limited thereto. In some embodiments, the length of the support structure 120 may be less than or equal to the length of the cooling structure 130 described below, but is not limited thereto.

[0082] The upstream end of the tubular structure included in the support structure 120 can be connected to the downstream end of the tubular structure included in the cooling structure 130. In other words, one end located on one side (downstream) of the support structure 120 can be connected to the end located on the opposite side (upstream) of the cooling structure 130, and the other end located on the other side (upstream) of the support structure 120 can be connected to one end of the medium section 110. Therefore, the aerosol formed in the medium section 110 can move through the cavities 120H and 130H in the direction of the mouthpiece section 140 (i.e., the downstream direction).

[0083] The support structure 120 may include at least one of cellulose acetate or lyocell. In particular, the support structure 120 may include a tubular structure made of cellulose acetate material and / or a tubular structure made of lyocell material comprising a plurality of lyocell fibers. In some embodiments, the support structure 120 may be a tubular filter tip made of cellulose acetate fibers or a tubular filter tip made of lyocell fibers. In some embodiments, the support structure 120 may be a tubular structure comprising cellulose acetate fibers (e.g., a tubular filter tip). In some embodiments, the support structure 120 may be a tubular structure made of lyocell material comprising a plurality of lyocell fibers (e.g., a tubular filter tip). The support structure 120 can effectively prevent the medium portion 110 from moving downstream when the heating element is inserted, and can also provide the effect of filtering and cooling aerosols.

[0084] Preferably, the support structure 120 may comprise a tow of lyocell fibers or a tubular structure composed of lyocell fibers. However, it is not limited thereto; alternatively or additionally, the support structure 120 may also comprise a cellulose acetate material or a tubular structure made of cellulose acetate material. Because the support structure 120 includes a cavity and comprises a tow of lyocell fibers or is composed of lyocell fibers, the support structure 120 can prevent deformation caused by heat applied to heat the smoking article 100 and / or by high-temperature aerosols passing through the cavity 120H of the support structure 120 due to the high heat resistance of the lyocell fibers, which will not melt even at high temperatures. Therefore, the support structure 120 can maintain its shape during smoking, ensuring that the smoke composition passing through the cavity 120H of the support structure 120 remains uniform and unchanged during the smoking time, thereby providing the user with a superior smoking experience.

[0085] On the other hand, preferably, the support structure 120 is manufactured to have appropriate hardness and / or durability in order to provide support. In some embodiments, when the support structure 120 comprises cellulose acetate, the hardness of the support structure 120 can be adjusted by regulating the amount of plasticizer added when manufacturing the support structure 120 using the aforementioned cellulose acetate. Furthermore, as the inner diameter of the support structure 120 increases (e.g., as the difference between the outer and inner diameters of the support structure 120 decreases), the amount of added plasticizer may also increase. In some other embodiments, the support structure 120 may also be manufactured by inserting a structure such as a membrane and / or tube made of the same or different materials inside (especially the cavity 120H).

[0086] In some other embodiments, when the support structure 120 comprises lyocell fibers, the support structure 120 may be a lyocell filter with an internal cavity 120H and an adhesive added. Unlike cellulose acetate, lyocell fibers do not contain plasticizers that harden the lyocell fibers; instead, the support structure 120 can be appropriately stiffened by the addition of an adhesive. That is, by including an adhesive in the support structure 120, excellent stiffness can be achieved even though it is a lyocell filter comprising lyocell filaments.

[0087] In some embodiments, the adhesive may include at least one of cellulose adhesives, vinyl adhesives, polyester adhesives, dextrin adhesives, starch adhesives, guar gum, xanthan gum, gum arabic, carrageenan, and konjac agar, but is not limited thereto; any substance capable of binding multiple lyocell fibers together and imparting appropriate stiffness may be used. For example, examples of cellulose adhesives may include hydroxypropyl methylcellulose (HPMC), ethyl cellulose (EC), methyl cellulose (MC), carboxymethyl cellulose (CMC), etc.; examples of the aforementioned vinyl adhesives may include polyvinylpyrrolidone (PVP), polyvinyl alcohol (PVA), ethylene-vinyl acetate copolymer (EVAc), etc.; the aforementioned polyester adhesives may be polyesters comprising at least one of the group consisting of alkylene, aryl, and heteroaryl groups having 5 to 12 carbon atoms; dextrin adhesives may include dextrin, etc.; and starch adhesives may include starch (e.g., cassava, corn, wheat, potato, sweet potato, etc.), cationic starch, esterified starch, etc., but are not limited thereto.

[0088] In some embodiments, the adhesive may include at least one of the following: polyester, hydroxypropyl methylcellulose (HPMC), ethyl cellulose (EC), methyl cellulose (MC), carboxymethyl cellulose (CMC), polyvinylpyrrolidone (PVP), polyvinyl alcohol (PVA), ethylene-vinyl acetate copolymer (EVAc), dextrin, tapioca starch, corn starch, wheat starch, potato starch, sweet potato starch, cationic starch, esterified starch, guar gum, xanthan gum, gum arabic, carrageenan, konjac, and agar.

[0089] In some embodiments, the support structure 120 may be a flavored filter tip with added flavoring substances such as menthol (i.e., flavored). In this case, the flavor expression of the smoking article 100 may be enhanced. In some embodiments, the support structure 120 may be a flavored filter tip with added menthol (i.e., flavored).

[0090] The cooling structure 130 can be used as a cooling component for the high-temperature aerosol generated in the heating medium section 110. Specifically, the cooling structure 130 may include a tubular structure with an internal cavity 130H, capable of cooling the aerosol passing through the cavity 130H. The cavity 130H may extend along the length direction of the cooling structure 130. The cavity 130H may be located at the center of a cross-section perpendicular to the length direction of the cooling structure 130 and extend along the length direction of the cooling structure 130. The cavity 130H and the cooling structure 130 may be coaxial along the length direction. The cavities 120H of the support structure 120 and 130H of the cooling structure 130 may be located at the center of cross-sections perpendicular to the length directions of the support structure 120 and 130 respectively, and extend along the length directions of the support structure 120 and 130. The cavities 120H of the support structure 120 and 130H of the cooling structure 130 may extend along the same axis in the length direction. The cavities 120H of the support structure 120 and 130H of the cooling structure 130 may have the same or different diameters in a cross-section perpendicular to the aforementioned axis. Specifically, the aerosol formed in the medium section 1130 can move through the cavity 120H of the support structure 120 to the cavity 130H of the cooling structure 130, and then move towards the mouthpiece section 140 (i.e., downstream). This allows the user to inhale aerosol at an appropriate temperature, and the mainstream smoke can be smoothly atomized, thereby increasing the atomization amount.

[0091] In some embodiments, the cooling structure 130 may include at least one of a tubular structure made of paper material, a tubular structure made of cellulose acetate material, and a tubular structure made of lyocell material. The length of the cooling structure 130 may be from about 12 mm to 16 mm (e.g., 14 mm), but is not limited thereto.

[0092] Preferably, the cooling structure 130 may comprise a tow of lyocell fibers or a tubular structure composed of lyocell fibers. However, it is not limited thereto; alternatively or additionally, the cooling structure 130 may comprise a tubular structure made of cellulose acetate material and / or a paper tube. Because the cooling structure 130 includes a cavity and comprises a tow of lyocell fibers or is composed of lyocell fibers, the high heat resistance of the lyocell fibers, which do not melt even at high temperatures, prevents deformation of the cooling structure 130 due to heat applied to heat the smoking article 100 and / or high-temperature aerosols passing through the cavity 130H of the cooling structure 130. Therefore, the cooling structure 130 maintains its shape during smoking, ensuring that the smoke composition passing through the cavity 130H of the cooling structure 130 remains uniform and unchanged throughout the smoking time, thereby providing a superior smoking experience for the user. When the cooling structure 130 includes a lyocell filament bundle, the cooling structure 130 may also include one or more adhesives dispersed in the lyocell filament bundle to impart a predetermined stiffness.

[0093] In some embodiments, the adhesive included in the cooling structure 130 may include, but is not limited to, the exemplary materials listed in the adhesive included in the support structure 120.

[0094] In some embodiments, the adhesive included in the cooling structure 130 may be the same as or different from the adhesive included in the support structure 120.

[0095] In some embodiments, the adhesive included in the cooling structure 130 may include at least one of the following: polyester, hydroxypropyl methylcellulose (HPMC), ethyl cellulose (EC), methyl cellulose (MC), carboxymethyl cellulose (CMC), polyvinylpyrrolidone (PVP), polyvinyl alcohol (PVA), ethylene-vinyl acetate copolymer (EVAc), dextrin, tapioca starch, corn starch, wheat starch, potato starch, sweet potato starch, cationic starch, esterified starch, guar gum, xanthan gum, gum arabic, carrageenan, konjac, and agar.

[0096] The mouthpiece portion 140 is a mouthpiece that contacts the user's mouth and can be used as a filter to ultimately deliver aerosols transferred from upstream to the user. The mouthpiece portion 140 may be located downstream of the cooling structure 130, and the upstream of the mouthpiece portion 140 may be connected to the downstream of the cooling structure 130 and / or may form the downstream end of the smoking article 100.

[0097] In some embodiments, the mouthpiece portion 140 may be made of cellulose acetate filter and / or lyocell filter. That is, the mouthpiece portion 140 may be manufactured using cellulose acetate fibers (i.e., cellulose acetate tow) as the filter material and / or lyocell fibers (i.e., lyocell tow) as the filter material. Although not shown in the figures, the mouthpiece portion 140 may also be made of a recessed filter. The length of the mouthpiece portion 140 may be from about 10 mm to 14 mm (e.g., 12 mm), but is not limited thereto.

[0098] In some embodiments, the mouthpiece portion 140 may include at least one capsule. The capsule may be a structure in which a solution of contents, including a flavoring agent, is encapsulated in a thin film. For example, the capsule may have a spherical or cylindrical shape.

[0099] For reference, the support structure 120, cooling structure 130, and mouthpiece 140 can all be used as a filter for aerosols. To emphasize their function as filters, each component can also be referred to as a "filter section". For example, the support structure 120, cooling structure 130, and mouthpiece 140 can also be referred to as the first filter section, the second filter section, and the third filter section, respectively.

[0100] The wrapping paper 150 can cover at least one of the media section 110, support structure 120, cooling structure 130, front filter section 111, and mouthpiece section 140 for packaging. Although not shown in the figures, at least one of the media section 110, support structure 120, cooling structure 130, front filter section 111, and mouthpiece section 140 can be individually wrapped with wrapping paper before being wrapped with wrapping paper 150. For example, the media section 110 can be wrapped with media section wrapping paper (not shown in the figures), and the support structure 120, cooling structure 130, and mouthpiece section 140 can be wrapped with first filter wrapping paper (not shown in the figures), second filter wrapping paper (not shown in the figures), and third filter wrapping paper (not shown in the figures), respectively. However, the packaging method of the smoking product 100 and its constituent elements is not limited to this and can be changed.

[0101] In some embodiments, the packaging paper 150 may be formed with perforations 160 arranged circumferentially along the cooling structure 130 (see reference). Figure 1 It can also be without perforation (no perforation, see reference). Figure 2 In some embodiments, the packaging paper 150 may be formed with perforations 160 arranged circumferentially along the cooling structure 130, particularly along a cross section perpendicular to the length direction of the cooling structure 130 (see reference). Figure 1When perforations are formed on the packaging paper 150, external air can flow into the interior of the cooling structure 130 through the multiple perforations 160. The flow of external air through the multiple perforations 160 can affect the surface temperature of the mouthpiece and the temperature of the mainstream smoke transmitted to the smoker. However, it is not limited to this; perforations may not be formed on the packaging paper 150. Even when perforations are not formed on the packaging paper 150, as described below, due to the excellent hydrophilicity of the lyocell material constituting the support structure 120, the moisture absorption performance in the mainstream smoke is excellent, thereby significantly reducing the heat sensation of the mainstream smoke after passing through the support structure 120.

[0102] The structure and effects of the present invention will be described in more detail below through embodiments and comparative examples. However, these embodiments are only used to further illustrate the present invention, and the scope of the present invention is not limited to these embodiments.

[0103] Example 1 and Comparative Example 1 Lyocell filters were manufactured using Lyocell tow with a single fineness of 3.33 dtex (denier number of 3.0) and a total fineness of 3,889 tex (total denier number of 35,000) according to the conditions of Example 1 shown in Table 1. Meanwhile, cellulose acetate filters with plasticizer added to cellulose acetate tow having a single fineness of 3.00 dtex (denier number of 2.7) and a total fineness of 3,889 tex (total denier number of 35,000) were manufactured according to the conditions of Comparative Example 1 shown in Table 1.

[0104] [Table 1]

[0105] Experimental Example 1. Evaluation based on the heat resistance of filter tip materials To evaluate the heat resistance of the filter tip material, the filter tips of Example 1 and Comparative Example 1 were heated to above 250°C using external heating under internal conditions of approximately 22±2°C and approximately 60±5% relative humidity. Images of the filter tips before heating were taken. Figure 3 As shown in (a), the heated filter tip is photographed, and it appears as follows: Figure 3 As shown in (b).

[0106] Figure 3 In (a), the left side shows the filter tip of Comparative Example 1 before heating, and the right side shows the filter tip of Example 1 before heating. Figure 3 (b) shows the filter tip of Comparative Example 1 after heating on the left and the filter tip of Example 1 after heating on the right.

[0107] Reference Figure 3It can be confirmed that the cellulose acetate filter tip of Comparative Example 1 has a significantly different shape before and after heating, and melts upon heating, leaving no substantial shape. Conversely, it can be confirmed that the lyocell filter tip of Example 1 only produces partial scorch marks after heating, and its shape is substantially similar before and after heating. This confirms that cellulose acetate is a fiber with an amorphous structure, has weak heat resistance, and will completely melt, while lyocell fiber has high heat resistance.

[0108] Example 2 and Comparative Example 2 Lyocell filters with a length of 84 mm were manufactured by wrapping a lyocell tow with a single fineness of 3.33 dtex (3.0 denier) and a total fineness of 3,889 tex (35,000 denier) in roll paper. Simultaneously, cellulose acetate tow with a single fineness of 3.00 dtex (2.7 denier) and a total fineness of 3,889 tex (35,000 denier) was coated with a plasticizer and wrapped in roll paper, and cellulose acetate filters with a length of 84 mm were manufactured according to the conditions shown in Comparative Example 2 in Table 2.

[0109] [Table 2]

[0110] Experimental Example 2. Evaluation based on the glycerol dispersibility (diffusion) of the filter tip material. In the filter tips of Examples 2 and Comparative Example 2, glycerol at a rate of 4 mg / mm (i.e., 4 mg per 1 mm along the length direction) was injected into each filament bundle using a nozzle. Each filter tip with injected glycerol was then subjected to a conditioning period of one week at an internal temperature of approximately 22 ± 2°C and an internal relative humidity of approximately 60 ± 5%. To confirm the degree of diffusion within the filter tips, cross-sectional images of each filter tip of Examples 2 and Comparative Example 2 were taken. Figure 4 As shown.

[0111] Reference Figure 4 (a) It can be confirmed that, on the cross-section of the filter tip of Comparative Example 2, in which glycerin was injected into the cellulose acetate filter tip, the added glycerin was generally concentrated only in the central part and diffused only in one direction, forming a stain. Conversely, referring to... Figure 4 (b) It can be confirmed that no stains were formed on the cross-section of the filter tip of Example 2, in which glycerol was injected into the Lyocell filter tip. This shows that in a cellulose acetate filter tip, glycerol cannot move and diffuse smoothly within the cellulose acetate filament bundle, while in a Lyocell filter tip, glycerol can move and diffuse smoothly within the Lyocell filament bundle.

[0112] Therefore, when the front-end filter section 111 is constructed using lyocell fiber bundles, even if a humectant (e.g., glycerin) is added to the front-end filter section 111, the humectant can still be uniformly dispersed within the front-end filter section 111 located at the very front of the smoking article 100, thereby minimizing leakage of the humectant from the front-end filter section 111 to the outside. Furthermore, during the storage and / or distribution of the smoking article 100, the humectant can be uniformly dispersed within the lyocell fiber bundle, thereby preventing leakage of the humectant from the smoking article 100 to the outside, thus reducing the amount of humectant remaining in the front-end filter section 111 and preventing a reduction in the amount of vaporization during smoking.

[0113] Example 3 Lyocell filters were manufactured using lyocell tows with a single denier of 3.33 dtex (3.0 denier) and a total denier of 3,889 dtex (35,000 total denier). The packaging paper used for manufacturing the filters was 75 gsm roll paper (untreated for oil resistance).

[0114] [Table 3]

[0115] Subsequently, the filter tip of Example 3 above was cut into 5mm pieces, such as... Figure 1 The smoking article 100 shown is a heated cigarette (as a smoking article) having a front filter section with a filter tip of Example 3 having a length of 5 mm, a medium section having a length of 7 mm, a support structure made of cellulose acetate material with an inner diameter of 2.7 mm, an outer diameter of 7 mm, and a length of 10 mm, a cooling structure made of paper tube having an inner diameter of 6 mm and a length of 14 mm, and a mouthpiece section made of cellulose acetate filaments having a length of 12 mm. The smoking article was manufactured according to the conditions shown in Table 4 below. Hereinafter, unless otherwise stated, PDC may refer to the draw resistance value measured with the medium section open, the perforation of the filter tip closed, and external air prevented from entering, while PDO may refer to the draw resistance value measured with the medium section open, the perforation of the filter tip not closed, and external air allowed to enter.

[0116] [Table 4]

[0117] (In Table 3 above, the ventilation rate (Vent) represents the ventilation rate (VR).) Example 3. Evaluation based on the aerosol composition of the filter tip material The medium section of the smoking product of Example 3 was heated externally at a temperature of 190°C to 280°C. The total particulate matter (TPM), nicotine content, and moisture content in the generated aerosol were measured, and the nicotine residue in the front-end filter section was also measured. The results are listed in Table 5 below.

[0118] Specifically, the experiment was conducted on the smoking product according to Example 3 in a smoking room with an internal temperature of approximately 22±2°C and an internal relative humidity of approximately 60±5% (specifically, a temperature of approximately 21.9°C and a relative humidity of 64.3%), under HC conditions (puff volume: 55 ml / puff frequency: 30 seconds / puff duration: 2 seconds / number of puffs: 9). The generated smoke was captured and analyzed after passing through a Cambridge filter (i.e., a Cambridge filter pad (CFP)). The total particulate matter (TPM) was measured as the change in weight of the Cambridge filter after smoking using the smoking device compared to the weight of the Cambridge filter before smoking. Other components were analyzed by gas chromatography (GC) of the captured smoke.

[0119] [Table 5]

[0120] Referring to Table 5 above, it can be confirmed that the amount of moisture migrating in the aerosol is 15.15 mg, which has an excellent effect on reducing the heat sensation for smokers, thereby improving the smoking experience. Furthermore, the amount of nicotine residue in the front filter section after smoking is 0.19 mg, confirming that the nicotine in the medium section moves upstream (i.e., in the opposite direction to the mouthpiece) after smoking. Therefore, since the front filter section is arranged to connect upstream of the medium section, it prevents the nicotine remaining in the front filter section from escaping into the aerosol generating device. This provides the advantage of preventing saliva generated during smoking from contaminating the aerosol generating device and keeping the device clean.

[0121] Figures 5 to 7 Examples illustrate various types of aerosol generating devices for smoking articles according to some embodiments of this disclosure. In particular, Figure 5 To illustrate a schematic structural diagram of the cigarette-type aerosol generating device 1000, Figure 6 and Figure 7This is a schematic structural diagram of a hybrid aerosol generating device 1000 that simultaneously uses liquid and cigarette smoke. The components of the aerosol generating device 1000 will be briefly described below.

[0122] like Figure 5 As shown, the aerosol generating device 1000 can be a device that generates aerosol by inserting a cigarette 2000 into its internal space. The cigarette 2000 can correspond to the smoking product 100 described above. Therefore, the cigarette 2000 can include the aforementioned medium section 110, front filter section 120, and mouthpiece section 140. More specifically, when the cigarette 2000 is inserted into the aerosol generating device 1000, the aerosol generating device 1000 can drive the heater section 1300 to generate aerosol from the cigarette 2000. The generated aerosol can be delivered to the user through the cigarette 2000.

[0123] As shown in the figure, the aerosol generating apparatus 1000 may include a battery 1100, a control unit 1200, and a heater unit 1300. However, Figure 5 Only the constituent elements relevant to embodiments of this disclosure are shown. Therefore, those skilled in the art to which this disclosure pertains will understand that other elements may also be included. Figure 5 Other common components besides those shown. For example, the aerosol generating apparatus 1000 may also include a display capable of outputting visual information and / or a motor for outputting tactile information, and / or at least one sensor (a suction detection sensor, a temperature detection sensor, and / or a cigarette insertion detection sensor, etc.). The components of the aerosol generating apparatus 1000 will be described below.

[0124] The battery 1100 supplies power for the operation of the aerosol generating apparatus 1000. For example, the battery 1100 can supply power to enable the heater section 1300 to operate, or it can supply power required for the operation of the control section 1200. In addition, the battery 1100 can supply power required for the operation of displays, sensors, and motors (not shown) installed in the aerosol generating apparatus 1000.

[0125] Secondly, the control unit 1200 can control the operation of the aerosol generating apparatus 1000 as a whole. In particular, the control unit 1200 can control not only the battery 1100 and the heater unit 1300, but also the operation of other components that may be included in the aerosol generating apparatus 1000. Furthermore, the control unit 1200 can determine whether the aerosol generating apparatus 1000 is in an operable state by checking the status of each component of the aerosol generating apparatus 1000.

[0126] The control unit 1200 may include at least one processor. The processor may be implemented using a plurality of logic gate arrays, or it may be implemented using a combination of a general-purpose microprocessor and a memory storing a program executable on the microprocessor. Furthermore, those skilled in the art to which this disclosure pertains will understand that the control unit 1200 may be implemented in other forms of hardware.

[0127] Secondly, the heater section 1300 can heat the cigarette 2000 using electricity supplied from the battery 1100. For example, when the cigarette 2000 is inserted into the aerosol generating device 1000, the heating element of the heater section 1300 is inserted into a portion of the inner side of the cigarette 2000 to increase the temperature of the aerosol forming substrate in the cigarette 2000.

[0128] In some embodiments, different Figure 5 As shown, alternatively or additionally, the heater section 1300 may also include an external heating element. In this case, the heating element of the heater section 1300 may be arranged outside the cigarette 2000 inserted into the device 1000. Furthermore, unlike the figures, the heater section 1300 may also include multiple heating elements. For example, the heater section 1300 may include multiple internal heating elements or multiple external heating elements. As another example, the heater section 1300 may also include one or more internal heating elements and / or one or more external heating elements.

[0129] The heating element described above can be made of resistive material and / or any material capable of inductive heating. However, the present invention is not limited thereto; any material can be used as long as it can be heated to the desired temperature under the control of the control unit 1200. The desired temperature can be preset in the aerosol generating device 1000, or it can be set by the user.

[0130] On the other hand, although Figure 5 The diagram shows the battery 1100, control unit 1200, and heater unit 1300 arranged in a row along the length direction, but the internal structure of the aerosol generating device 1000 is not limited to this. Figure 5 The example shown. In other words, the arrangement of the battery 1100, control unit 1200 and heater unit 1300 can be changed according to the design of the aerosol generating device 1000.

[0131] In the following text, reference will be made to Figure 6 and Figure 7 Description of the mixed aerosol generating apparatus 1000. For clarity of this disclosure, descriptions of repeating components 1100, 1200, and 1300 will be omitted.

[0132] like Figure 6 or Figure 7As shown, the aerosol generating apparatus 1000 may also include a vaporizer 1400.

[0133] When the cigarette 2000 is inserted into the aerosol generating device 1000, the aerosol generating device 1000 can generate aerosol from the cigarette 2000 and / or the vaporizer 1400 by driving the heater section 1300 and / or the vaporizer 1400. The aerosol generated by the heater section 1300 and / or the vaporizer 1400 can be delivered to the user through the cigarette 2000. When the cigarette 2000 is inserted into the aerosol generating device 1000, the heating element of the heater section 1300 is arranged in contact with or adjacent to a portion of the outer side of the cigarette 2000, so as to externally increase the temperature of the aerosol forming substrate in the cigarette 2000.

[0134] The vaporizer 1400 can generate an aerosol by heating a liquid composition, and the generated aerosol can be delivered to the user via the cigarette 2000. In other words, the aerosol generated by the vaporizer 1400 can move along the airflow path of the aerosol generating device 1000, and the airflow path can be configured such that the aerosol generated by the vaporizer 1400 is delivered to the user via the cigarette 2000.

[0135] The vaporizer 1400 may include, but is not limited to, a liquid storage chamber, a liquid transfer unit, and a liquid heating element. For example, the liquid storage chamber, the liquid transfer unit, and the liquid heating element may be included as independent modules in the aerosol generating device 1000.

[0136] The reservoir can store a liquid composition (i.e., a liquid aerosol forming substrate). The reservoir can be made to be detachable from or installed on the vaporizer 1400, or it can be integrated with the vaporizer 1400.

[0137] Secondly, the liquid transfer unit can transfer the liquid composition in the storage chamber to the liquid heating element. For example, the liquid transfer unit can be a core such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic, but is not limited to these.

[0138] A liquid heating element is a component used to heat a liquid composition transferred by a liquid transfer unit. For example, the liquid heating element can be a metal heating wire, a metal heating plate, a ceramic heater, etc., but is not limited to these. Furthermore, the liquid heating element can be made of a conductive wire such as nickel-chromium wire, or it can be arranged in a structure wound around the liquid transfer unit. The liquid heating element can be heated by a current supply from the control unit 1200, and the liquid composition can be heated by transferring heat to the liquid composition in contact with the liquid heating element. As a result, an aerosol can be generated.

[0139] like Figure 6 or Figure 7As shown, the vaporizer 1400 and the heater section 1300 can be arranged in parallel or in series. However, the scope of this disclosure is not limited to the above-described arrangement.

[0140] For reference, the vaporizer 1400 may be used interchangeably with terms in the art such as cartomizer or atomizer.

[0141] The control unit 1200 can further control the operation of the vaporizer 1400, and the battery 1100 can further supply power to enable the vaporizer 1400 to operate.

[0142] At this point, we have referred to Figures 5 to 7 Various types of aerosol generating apparatus 1000 that can be applied to smoking articles 100 according to some embodiments of the present disclosure are described.

[0143] While embodiments of the present disclosure have been described above with reference to the accompanying drawings, those skilled in the art will understand that the present disclosure can be implemented in other specific forms without altering the technical concept or essential features. Therefore, it should be understood that the above embodiments are exemplary in all respects and not restrictive. The scope of protection of this disclosure should be determined by the claims and should be interpreted as including all technical ideas within its equivalent scope as falling within the scope of the technical ideas defined by this disclosure.
