Description

Technical Field

[0001] This invention relates to a smoking article that, by including lyocell filament bundles in a tobacco stick containing tobacco material (e.g., which may be contained in a medium substrate), improves the placement rate of the tobacco material (e.g., which may be contained in a medium substrate) and prevents deformation of the medium portion due to heat applied to heat the smoking article, thereby providing a more enhanced smoking experience for the user (consumer). Background Technology

[0002] Modern smoking substitution devices and related technologies employ various media sections to effectively transfer tobacco components. Typically, these devices utilize the following principle: by heating the cigarette to a high temperature of approximately 150°C to 300°C, this heat is transferred to the media section, raising its temperature and thus promoting the smooth transfer of tobacco components such as nicotine.

[0003] In particular, ingredients such as glycerin produce atomization (aerosol), which plays an important role in providing smokers with the satisfaction of smoking. However, if the device's heating temperature is set below the boiling point of glycerin, atomization cannot be produced smoothly, thus reducing the smoking experience.

[0004] To address this problem, existing technologies have developed methods that include a humectant in the medium section or use reconstituted tobacco leaves as the medium section. Specifically, existing technologies employ methods such as cutting reconstituted tobacco leaves containing a humectant into strips to form the medium section, or inserting sheet-like reconstituted tobacco leaves. While these methods improve performance to some extent, the following problems still exist.

[0005] First, during the process of inserting the cut reconstituted tobacco leaves into the media section, some of the cut reconstituted tobacco leaves may enter the internal structure of the equipment, such as the paper tube or air duct, causing contamination. This can lead to dirt buildup in the internal structure of the equipment or hinder the adhesion of the tobacco sticks.

[0006] Secondly, when using reconstituted tobacco made from a single material, it is difficult to add additional ingredients such as activated carbon and nicotine liquid during the manufacturing process. These additional ingredients help improve the transfer efficiency of tobacco components, but their application in the media structure based on reconstituted tobacco is limited.

[0007] To address the aforementioned issues, a method utilizing a folded paper substrate has been proposed. By incorporating activated carbon, nicotine salts, granules, and other components into the medium portion of the folded paper substrate, flexibility is provided in including a variety of ingredients. However, this method also has some limitations. Because the folded structure does not structurally bind the components sufficiently, the loss rate (shedding rate) of components during manufacturing is relatively high, and the paper substrate may produce a papery odor or other unpleasant smells, thus reducing the user's smoking experience.

[0008] Furthermore, existing technologies have explored the use of dual composite filter tips (e.g., activated carbon cellulose acetate filter tips) and cellulose acetate filter tips or single filter tips in the media section to stabilize and fix substances such as activated carbon, nicotine salts, and particles. Activated carbon cellulose acetate filter tips are suitable for effectively fixing components structurally, but the cellulose acetate tow that makes up the filter tip has the disadvantage of melting at high temperatures, making it difficult to use in high-temperature environments.

[0053] In this instruction manual, "rigid roll paper" refers to roll paper with a basis weight of a certain value or higher.

[0054] In some embodiments, "oil-resistant roll paper" can refer to roll paper whose surface has been treated with oil resistance, and "oil-resistant rigid roll paper" can refer to rigid roll paper whose surface has been treated with oil resistance.

[0055] In some embodiments, "general roll paper" may refer to roll paper whose surface has not been treated with oil resistance, and "general hard roll paper" may refer to hard roll paper whose surface has not been treated with oil resistance.

[0056] In this specification, the “monofilament” of lyocell or cellulose acetate bundles refers to the fineness of the monofilament separated from the multifilament of lyocell or cellulose acetate fibers that constitute the lyocell or cellulose acetate bundle.

[0057] In this specification, the “total fineness” of a lyocell tow or cellulose acetate tow refers to the fineness of the multiple strands of lyocell or cellulose acetate fibers that make up the lyocell tow or cellulose acetate tow.

[0058] 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 the use of the smoking article. In some embodiments, the filter of the smoking article can capture particulate matter (total particulate matter, hereinafter referred to as "TPM") comprising at least a portion of at least one of nicotine (hereinafter referred to as "Nic") and tar (hereinafter referred to as "TPM") contained in the smoke components generated when smoking with the smoking article.

[0059] 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%.

[0060] In this specification, "inhalation resistance" refers to the constant pressure difference between the two ends of the sample when airflow passes through it. In this specification, "PDC" refers to the value of inhalation resistance measured with the smoke stick open, the filter perforation closed, and external air prevented from entering, while "PDO" refers to the value of inhalation resistance measured with the smoke stick open, the filter perforation not closed, and external air allowed to enter. For example, inhalation resistance can be measured using the method specified in ISO standard 6565:2015. According to ISO standard 6565:2015, inhalation resistance is the constant 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 exhaust end.

[0061] In some embodiments, room temperature may refer to 20°C to 25°C.

[0062] In this specification, unless otherwise specified, the percentage of a component and the proportion of a component represent the weight percentage and the weight proportion of the component, respectively.

[0063] 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. Alternatively or additionally, the number of puffs can represent the maximum number of inhalation or introduction actions that the smoking article can provide before it is completely exhausted or ceases to function.

[0064] 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 be used when the perforated portion of the filter tip is sealed. When measuring under HC conditions, the number of puffs can be up to 9.

[0065] In this specification, the "ventilation rate" (hereinafter referred to as "Vent") of a smoking product can be defined as the percentage of the total volumetric airflow (e.g., ml / s) entering the unburned or unheated smoking product without passing through the front end region (i.e., the upstream end in the length direction) relative to the total volumetric airflow (e.g., ml / s) at the outlet end (i.e., the downstream end in the length direction) of the smoking product. For example, the air dilution rate can be measured according to ISO 9512:2019. For example, the total volumetric airflow entering the unburned or unheated smoking product without passing through the front end region can be the total volumetric airflow entering in a direction perpendicular to the length direction of the smoking product. For example, the total volumetric airflow entering the unburned or unheated smoking product without passing through the front end region can be the total volumetric airflow entering the smoking product through the cigarette paper.

[0066] The total particulate matter (TPM) content in the captured flue gas can be analyzed using gas chromatography-mass spectrometry (GC / MS). For example, for tar or nicotine, a Cambridge filter pad (CFP) for capturing flue gas components can be immersed in isopropyl alcohol (IPA) for a period of time (e.g., 20 minutes to 16 hours), then processed using a shaking device, and after removing impurities through a polytetrafluoroethylene (PTFE) syringe filter, the TPM content in the captured flue gas can be measured using GC / MS. The immersion time can be more than 20 minutes for tar or nicotine.

[0067] The amount of components (especially nicotine) remaining inside the filter tip (especially a Lyocell filter tip and / or Lyocell tow) and / or segments of a cigarette stick after smoking can be measured by immersing the cigarette stick, filter tip, and / or segments in water after smoking to extract the residual components (especially nicotine), followed by analysis using a GC / MS instrument. In this case, the cigarette stick, filter tip, and / or segments 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.

[0068] The aforementioned GC / MS equipment can be, for example, a measurement device from Agilent Technologies.

[0069] In the following, various embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0070] Figures 1 to 3 This is a diagram showing an example of inserting a smoking product into an aerosol generating device.

[0071] Reference Figure 1 The aerosol generating device 1 includes a battery 11, a control unit 12, and a heater 13. (See reference...) Figure 2 and Figure 3 The aerosol generating device 1 also includes a vaporizer 14. Furthermore, the smoking product 3 can be inserted into the internal space of the aerosol generating device 1.

[0072] Figures 1 to 3 The aerosol generating apparatus 1 shown illustrates the components relevant to this embodiment. Therefore, those skilled in the art related to this embodiment will understand that, in addition to… Figures 1 to 3 In addition to the components shown, other general components may also be included in the aerosol generating apparatus 1.

[0073] Furthermore, despite Figure 2 and Figure 3 The aerosol generating device 1 shown includes a heater 13, but the heater 13 may be omitted if necessary. In some embodiments, the aerosol generating device 1 does not include a heater. In some embodiments, the battery 11, the control unit 12, and the vaporizer 14 are arranged sequentially along the length of the smoking article 3, i.e., in a row.

[0074] exist Figure 1 The image shows the battery 11, control unit 12, and heater 13 arranged in a row. In some embodiments, the battery 11, control unit 12, and heater 13 are arranged sequentially along the length of the smoking product 3. Furthermore, Figure 2The battery 11, control unit 12, vaporizer 14, and heater 13 are arranged in a row along the length of the smoking product 3. In some embodiments, the battery 11, control unit 12, vaporizer 14, and heater 13 are arranged sequentially along the length of the smoking product 3, i.e., in a row. Additionally, Figure 3 The vaporizer 14 and heater 13 are shown arranged side by side. However, the internal structure of the aerosol generating device 1 is not limited to... Figures 1 to 3 The structure shown. In other words, depending on the design of the aerosol generating device 1, the arrangement of the battery 11, control unit 12, heater 13, and vaporizer 14 can vary. In some embodiments, the battery 11, control unit 12, and heater 13 are arranged sequentially along the length of the smoking article 3.

[0075] When the smoking product 3 is inserted into the aerosol generating device 1, the aerosol generating device 1 can generate aerosol by operating the heater 13 and / or the vaporizer 14. The aerosol generated by the heater 13 and / or the vaporizer 14 passes through the smoking product 3 and is delivered to the user.

[0076] If necessary, the aerosol generating device 1 can heat the heater 13 even if the smoking product 3 is not inserted into the aerosol generating device 1.

[0077] Battery 11 supplies power for the operation of aerosol generating device 1. For example, battery 11 can supply power for heating heater 13 or vaporizer 14, and for the operation of control unit 12. In addition, battery 11 can also supply power for the operation of displays, sensors, motors, etc., installed on aerosol generating device 1.

[0078] The control unit 12 provides overall control over the operation of the aerosol generating device 1. Specifically, the control unit 12 controls not only the operation of the battery 11, heater 13, and vaporizer 14, but also the operation of other components included in the aerosol generating device 1. Furthermore, the control unit 12 can check the status of each component of the aerosol generating device 1, thereby determining whether the aerosol generating device 1 is in a state where it can operate.

[0079] The control unit 12 includes at least one processor. The processor can be implemented using a plurality of logic gate arrays, or it can 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 embodiment pertains will understand that the control unit can be implemented in other forms of hardware.

[0080] The heater 13 can be heated by electricity supplied from the battery 11. For example, when the smoking article 3 is inserted into the aerosol generating device 1, the heater 13 can be located outside the smoking article 3. Therefore, the heated heater 13 can raise the temperature of the aerosol generating substance inside the smoking article 3.

[0081] Heater 13 can be a resistance heater. For example, heater 13 may include a conductive track in which current flows, and heater 13 can be heated. However, heater 13 is not limited to the above example; any heater capable of heating to the desired temperature is applicable. Here, the desired temperature can be preset in the aerosol generating device 1, or it can be set by the user.

[0082] On the other hand, as another example, heater 13 can be an induction heating heater. In particular, heater 13 may include a conductive coil for heating the smoking article 3 by induction heating, and the smoking article 3 may include a sensor capable of being heated by the induction heating heater.

[0083] For example, heater 13 may include tubular heating elements, plate heating elements, needle heating elements and / or rod heating elements, which can heat the interior and / or exterior of smoking article 3 depending on the shape of the heating elements.

[0084] Furthermore, the aerosol generating apparatus 1 may also include multiple heaters 13. In this case, the multiple heaters 13 can be arranged either inside the smoking article 3 or outside the smoking article 3. Alternatively, some of the multiple heaters 13 can be inserted inside the smoking article 3, while the remaining heaters are arranged outside the smoking article 3. In some embodiments, the heaters 13 can heat both the inside and outside of the smoking article 3. Additionally, the shape of the heaters 13 is not limited to... Figures 1 to 3 The shape shown can be manufactured in various shapes. In some embodiments, heater 13 may include a resistance heater and an induction heater.

[0085] The vaporizer 14 generates an aerosol by heating the liquid composition, and the generated aerosol can pass through the smoking article 3 and be delivered to the user. In other words, the aerosol generated by the vaporizer 14 can move along the airflow passage of the aerosol generating device 1, and the airflow passage can be configured such that the aerosol generated by the vaporizer 14 can pass through the smoking article 3 and be delivered to the user. The vaporizer 14 generates an aerosol by heating the liquid composition and releases the aerosol toward the smoking article, causing it to pass through the smoking article inserted in the smoking article insertion part.

[0086] For example, the vaporizer 14 may include, but is not limited to, a liquid storage unit, a liquid transfer unit, and a heating element. For example, the liquid storage unit, the liquid transfer unit, and the heating element may be included as independent modules in the aerosol generating apparatus 1.

[0087] The liquid storage unit can store a liquid composition. For example, the liquid composition can be a liquid containing tobacco-containing materials with volatile tobacco flavoring components, or it can be a liquid containing non-tobacco materials. The liquid storage unit can be made detachable / installable on the vaporizer 14, or it can be integrally formed with the vaporizer 14.

[0088] For example, the liquid-phase composition may include water, solvent, ethanol, plant extracts, fragrances, flavorings, and / or vitamin mixtures. Fragrances may include, but are not limited to, menthol, peppermint, spearmint oil, and / or various fruit flavorings. Flavorings may include ingredients capable of providing the user with a variety of aromas or flavors. Vitamin mixtures may be, but are not limited to, a mixture of at least one of vitamins A, B, C, and E. Additionally, the liquid-phase composition may contain aerosol forming agents such as glycerol and propylene glycol.

[0089] The liquid transfer unit can transport the liquid phase composition in the liquid storage section to the 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 this.

[0090] A heating element is a component used to heat a liquid-phase composition transported by a liquid transfer unit. For example, the heating element can be a hot metal wire, a hot metal plate, a ceramic heater, etc., but is not limited to these. Furthermore, the heating element can be made of conductive wire such as a nickel-chromium alloy wire, and can be arranged in a structure wound around the liquid transfer unit. The heating element can be heated by an electric current supply, and the liquid-phase composition can be heated by transferring heat to the liquid-phase composition in contact with the heating element. As a result, an aerosol can be generated.

[0091] For example, vaporizer 14 may be referred to as a cartomizer or atomizer, but is not limited to these terms.

[0092] On the other hand, in addition to the battery 11, control unit 12, heater 13, and vaporizer 14, the aerosol generating device 1 may include other general components. For example, the aerosol generating device 1 may include a display capable of outputting visual information and / or a motor for outputting tactile information. Furthermore, the aerosol generating device 1 may include at least one sensor (a suction detection sensor, a temperature detection sensor, and / or a smoking product insertion detection sensor, etc.). Moreover, the aerosol generating device 1 may be configured to allow external air to flow in or internal gas to escape even when the smoking product 3 is inserted.

[0093] Despite Figures 1 to 3 Although not shown, the aerosol generating device 1 can also be configured as a system with a separate cradle. For example, the cradle can be used to charge the battery 11 of the aerosol generating device 1. Alternatively or additionally, the heater 13 can also be heated while the cradle and the aerosol generating device 1 are combined.

[0094] The smoking product 3 can be similar to a general combustion-type smoking product. For example, the smoking product 3 can be divided into a cigarette stick 31 containing tobacco material and aerosol-generating substances and a filter stick 32 including a filter tip, etc. Optionally, the filter stick 32 of the smoking product 3 may also contain aerosol-generating substances. For example, aerosol-generating substances in the form of particles or capsules can be inserted into the cigarette stick 31 and selectively also inserted into a portion of the filter stick 32.

[0095] The entire cigarette stick 31 is inserted into the aerosol generating device 1, while the filter stick 32 can protrude to the outside. Alternatively, only a portion of the cigarette stick 31 can be inserted into the aerosol generating device 1, or both the entire cigarette stick 31 and a portion of the filter stick 32 can be inserted. The user can inhale the aerosol while holding the filter stick 32 in their mouth. At this time, as outside air passes through the cigarette stick 31, aerosol is generated, and the generated aerosol passes through the filter stick 32 and is delivered to the user's mouth.

[0096] In some embodiments, external air can be introduced through at least one air passage formed in the aerosol generating device 1. For example, the opening and closing of the air passage formed in the aerosol generating device 1 and / or the size of the air passage can be adjusted by the user. Therefore, the user can adjust the amount of vaporization, the smoking sensation, etc. As another example, external air can be introduced into the interior of the smoking article 3 through at least one hole formed on the surface of the smoking article 3.

[0097] The following will refer to Figure 4 Explain the structure of smoking products.

[0098] Reference Figure 4The smoking product 3 includes a tobacco stick 31, a filter rod 32, and a front plug 33. The tobacco stick 31 includes a medium substrate (or tobacco material) and an aerosol-generating substance. The tobacco material may be a cigarette.

[0099] In some embodiments, in a smoking article, the filter rod 32, the cigarette rod 31, and the front plug 33 are arranged sequentially along the length of the smoking article 3.

[0100] The filter rod 32 may be adjacent to one side or the rear end of the cigarette rod 31. The filter rod 32 may include a first section 321 for cooling the aerosol and a second section 322 for filtering specified components contained in the aerosol. In some embodiments, the first section 321 is disposed between the cigarette rod 31 and the second section 322.

[0101] In this specification, in order to emphasize the function of the first section 321 and the second section 322 as a filter, the first section 321 may be referred to as the cooling structure 321 and the second section 322 may be referred to as the mouthpiece section 322.

[0102] With the cigarette stick 31 as a reference, the front plug 33 can be located on the side opposite to the filter rod 32 or on the opposite side of one side of the cigarette stick 31, i.e., the other side. The front plug 33 can be adjacent to the front end of the cigarette stick 31. The front plug 33 can prevent the cigarette stick 31 from detaching to the outside and prevent the liquid-phase aerosol from flowing from the cigarette stick 31 into the aerosol generating device during smoking. Figures 1 to 3 (See attached figure "1").

[0103] The smoking product 3 can be packaged by at least one packaging material 35. The packaging material 35 can surround the smoking product 3. In some embodiments, the smoking product 3 can be packaged by having at least a portion of the smoking product 3 surrounded by at least one packaging material 35. For example, the front plug 33 can be packaged by a first packaging material 351, the cigarette stick 31 can be packaged by a second packaging material 352, the first segment 321 can be packaged by a third packaging material 353, and the second segment 322 can be packaged by a fourth packaging material 354. Optionally, the entire smoking product 3 can be repackaged by a fifth packaging material 355. The fifth packaging material 355 can be referred to as the outer packaging material, while the first packaging material 351, the second packaging material 352, the third packaging material 353, and the fourth packaging material 354 surrounded by the fifth packaging material 355 can be referred to as the inner packaging material.

[0104] The diameter of the smoking article 3 can be in the range of 5 mm to 9 mm, but is not limited thereto. For example, the length of the front plug 33 can be about 4 mm to 20 mm (e.g., 7 mm), the length of the tobacco stick 31 can be about 13 mm to 17 mm (e.g., 15 mm), the length of the first section 321 can be about 7 mm to 20 mm (e.g., 12 mm), and the length of the second section 322 can be about 4 mm to 20 mm (e.g., 14 mm), but is not limited thereto.

[0105] In some embodiments, the cigarette stick 31 may include a lyocell tow containing a plurality of lyocell fibers and a plurality of media substrates filling the interior of the lyocell tow. In particular, the cigarette stick 31 may include a lyocell filter containing or composed of lyocell tow, and media substrates inserted uniformly or randomly along the interior of the lyocell filter into the entire region or a portion thereof.

[0106] In this invention, the lyocell fibers contained in the tobacco stick 31 can be environmentally friendly fibers 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.

[0107] In some embodiments, lyocell fibers may have an irregular cross-section. An irregular cross-section is defined as a shape whose cross-section is not circular but includes multiple protrusions. For example, a cross-section with multiple protrusions extending from the center can be referred to as an irregular cross-section.

[0108] 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 are not limited thereto. The terms mentioned herein have the same meaning as those described above.

[0109] When manufacturing the cigarette stick 31, the media substrate can be filled by inserting it into the interior of the lyocell tow. There can be spaces between the multiple lyocell fibers included in or constituting the lyocell tow, and the media substrate can be placed within these spaces. That is, the media substrate can be filled in a dispersed manner within the lyocell tow. Therefore, the media substrate is located within the spaces included in or constituting the lyocell tow, thus filling or placing it within the lyocell tow in a manner that allows it to be covered by the lyocell filter tip, preventing leakage to the outside.

[0110] During the manufacturing process of the cigarette stick 31, the medium substrate can be placed into or onto the fiber bundle, for example by free fall, while the fiber bundle constituting the filter tip is unfolded. The fiber bundle with the medium substrate is then wrapped or wound into a predetermined shape, such as a cylinder, thereby manufacturing the cigarette stick 31. Thus, the medium substrate can be inserted and filled in a random or uniform manner along the entire or a portion of the lyocell fiber bundle. In other words, the medium substrate can be located within the lyocell fiber bundle or in the space between the multiple lyocell fibers constituting the lyocell fiber bundle, and can be dispersedly filled inside the lyocell fiber bundle.

[0111] Since the filament bundle used to fill the medium substrate into the cigarette rod 31 according to the invention comprises a plurality of lyocell fibers having internal spaces or is composed of a lyocell filament bundle comprising a plurality of lyocell fibers having internal spaces, the placement rate of the medium substrate can be improved without additional additives for adhesion, compared to cellulose acetate plasticized by a plasticizer, thereby improving manufacturing process efficiency and the retention of the medium substrate. Furthermore, since the filament bundle used to fill the medium substrate into the cigarette rod 31 is composed of a lyocell filament bundle comprising a plurality of lyocell fibers having internal spaces, it is possible to prevent the medium substrate from being ejected from the paper surface due to the texture of the paper when inserted, thereby improving manufacturing process efficiency.

[0112] Furthermore, since the tobacco stick 31 includes a bundle of lyocell filaments, its excellent heat resistance effectively prevents the shape of the tobacco stick 31 from being deformed by the heat transferred from the heater used to heat the tobacco stick 31.

[0113] In some embodiments, the aforementioned media substrate may be a specific form of tobacco material. For example, the media substrate may be in the form of tobacco slices, tobacco particles, tobacco sheets, tobacco beads, tobacco granules, tobacco powder, and / or tobacco extracts. In particular, the tobacco material may include at least one of, for example, tobacco leaves, tobacco veins, expanded tobacco, cut tobacco, reconstituted tobacco, and reconstituted tobacco.

[0114] The cigarette stick 31 may also contain, for example, at least one of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol as aerosol generating substances, but is not limited thereto. In particular, the cigarette stick 31 may also contain other additives such as flavoring agents, humectants, and / or organic acids. Specifically, flavoring liquids such as menthol and / or humectants may be added to the cigarette stick 31. In particular, flavoring liquids such as menthol and / or humectants can be added by spraying onto the cigarette stick 31.

[0115] The shape of the filter rod 32 is not limited. For example, the filter rod 32 can be a cylindrical rod or a tubular rod with an internal cavity. In addition, the filter rod 32 can also be a grooved rod. If the filter rod 32 is composed of multiple segments, at least one of the multiple segments can be made into a different shape than the other segments.

[0116] The following details each section of filter rod 32.

[0117] The first section 321 of the filter rod 32 can cool the aerosol generated by the heater 13 heating the smoke rod 31. Therefore, the user can inhale the aerosol cooled to an appropriate temperature.

[0118] In some embodiments, the first segment 321 of the filter rod 32 may include at least one of a cellulose acetate filter tip, a paper tube, and a lyocell filter tip comprising a lyocell filament bundle containing a plurality of lyocell fibers. When the first segment 321 is a cellulose acetate filter tip and / or a lyocell filter tip, the first segment 321 may be a tubular structure comprising an internal cavity. The cavity may extend along the length direction of the first segment 321. The cavity may be located at the center of a cross-section perpendicular to the length direction of the first segment 321 and extend along the length direction of the first segment 321. The cavity 120H and the first segment 321 may be coaxial in the length direction. The length or diameter of the first segment 321 may vary depending on the form of the smoking article 3. For example, the length of the first segment 321 may be suitably selected in the range of 7 mm to 20 mm. Preferably, the length of the first segment 321 may be about 12 mm, but is not limited thereto.

[0119] When the cigarette rod 31 is inserted into the heater 13, the first section 321 prevents the internal material of the cigarette rod 31 from being pushed backward (i.e., in the opposite direction to the insertion direction) and also generates an aerosol cooling effect. When the first section 321 is a cellulose acetate filter with an internal cavity, the diameter of the cavity of the first section 321 can be appropriately selected in the range of 2 mm to 4.5 mm. When the first section 321 is a lyocell filter with an internal cavity, the diameter of the cavity of the first section 321 can be appropriately selected in the range of 2 mm to 5.5 mm. Its diameter can be 2 mm to 5.5 mm, preferably 2.1 mm to 5 mm, more preferably 2.2 mm to 4.5 mm, and even more preferably in the range of 2.5 mm to 4 mm, but is not limited thereto. When the first section 321 is a paper tube filter, its inner diameter can be appropriately selected in the range of 5 mm to 7.5 mm, more preferably in the range of 6 mm to 7 mm, but is not limited thereto.

[0120] When the first section 321 includes a lyocell filament bundle, the lyocell filament bundle has excellent heat resistance, which can effectively prevent the first section 321 from deforming due to heat transferred from the heater of the smoking article 3 or from the aerosol generated in the smoking article 3.

[0121] The second section 322 of the filter rod 32 can cool the aerosol generated by the heater 13 heating the cigarette rod 31. Therefore, the user can inhale the aerosol cooled to an appropriate temperature. In addition, the second section 322 is the mouthpiece that comes into contact with the user's mouth and serves as a filter that ultimately transfers the aerosol from upstream to the user.

[0122] The length of the second segment 322 can be appropriately selected within the range of 4mm to 20mm. For example, the length of the second segment 322 can be about 14mm, but it is not limited to this.

[0123] The second section 322 of the filter rod 32 can be a cellulose acetate filter or a lyocell filter. That is, the second section 322 can be manufactured using cellulose acetate fibers (especially cellulose acetate tows) as the filter material, or using lyocell fibers (especially lyocell tows) as the filter material. Although not shown in the figure, the second section 322 can also be made into a recessed filter.

[0124] During the manufacturing process of the second section 322, flavoring liquid can be sprayed onto the second section 322 to produce flavor. Alternatively or additionally, individual fibers coated with flavoring liquid can be inserted into the interior of the second section 322. As the aerosol generated from the tobacco stick 31 passes through the first section 321, the aerosol is cooled, and the cooled aerosol is delivered to the user through the second section 322. Therefore, when a flavoring element is added to the second section 322, an effect of increasing the persistence of the flavor delivered to the user can be achieved.

[0125] The interior of the second segment 322 may include at least one capsule 34. Here, the capsule 34 may have a structure in which a solution of contents, including a fragrance, is encapsulated by a thin film. For example, the capsule 34 may have a spherical or cylindrical shape.

[0126] The front plug 33 can prevent the liquid-phase aerosol from flowing from the cigarette stick 31 into the aerosol generating device during smoking. Figures 1 to 3 The function of the attached figure label "1").

[0127] The length or diameter of the front plug 33 can vary depending on the shape of the smoking article 3. For example, the length of the front plug 33 can be appropriately selected in the range of 4 mm to 20 mm. Preferably, the length of the front plug 33 can be about 7 mm, but it is not limited thereto.

[0128] The front plug 33 may be made of cellulose acetate and / or lyocell. Furthermore, the front plug 33 may include at least one channel internally, and the cross-sectional shape of the channel may be manufactured in various ways. For example, the cross-sectional shape of the channel formed internally in the front plug 33 may be formed into various shapes such as trefoil, tetralobite, multilobite, polygon, hard-edged shape, etc.

[0129] The following will describe the packaging material 35 in detail.

[0130] The first package 351 may be made of ordinary filter paper roll bonded with metal foil. In some embodiments, the first package 351 may be made of ordinary filter paper roll bonded with aluminum foil. The second package 352 and the third package 353 may be made of ordinary filter paper roll. For example, the second package 352 and the third package 353 may each be a perforated or non-perforated paper roll independently.

[0131] In some embodiments, the third package 353 covering the first section 321 has a basis weight of a predetermined value or higher, and may comprise oil-resistant rigid paper rolls treated with oil resistance and / or ordinary rigid paper rolls without oil resistance treatment, or may be constructed (i.e., made) from oil-resistant rigid paper rolls treated with oil resistance and / or ordinary rigid paper rolls without oil resistance treatment. On the other hand, since the third package 353 comprises rigid paper rolls with a basis weight of a predetermined value or higher, or is constructed from rigid paper rolls with a basis weight of a predetermined value or higher, it can not only serve to surround the packaging material including the first section 321 containing the lyocell filament bundle, but also to impart a predetermined level of hardness to the filter rod 32 according to the invention. The aforementioned third packaging material 353 may include general hard paper rolls of oil-resistant rigid paper and / or non-oil-resistant rigid paper rolls. In particular, it may include general hard paper rolls of oil-resistant rigid paper and / or non-oil-resistant rigid paper rolls with a basis weight of 30 gsm to 180 gsm, preferably 35 gsm to 170 gsm, more preferably 40 gsm to 160 gsm, even more preferably 50 gsm to 158 gsm, even more preferably 60 gsm to 155 gsm, even more preferably 70 gsm to 150 gsm, even more preferably in the range of 75 gsm to 150 gsm, but is not limited thereto.

[0132] The construction and effects of the present invention will be described in more detail below through embodiments and comparative examples. However, these embodiments are only for illustrating the present invention more specifically, and the scope of the present invention is not limited to these embodiments.

[0133] Example 1 and Comparative Example 1 Lyocell filters were manufactured using Lyocell tow with a single denier of 3.33 dtex (3.0 denier) and a total denier of 3889 tex (35000 total denier). Lyocell filters were manufactured under the conditions of Example 1 shown in Table 1. Meanwhile, cellulose acetate filters with plasticizer added to cellulose acetate tow having a single denier of 3.00 dtex (2.7 denier) and a total denier of 3889 tex (35000 total denier) were manufactured under the conditions of Comparative Example 1 shown in Table 1.

[0134] Table 1

[0135] 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 over 250°C using external heating under internal conditions of approximately 22±2°C and approximately 60±5% relative humidity. The filter tips before heating were photographed. Figure 5 As shown in part (a), and photographed after heating the filter tip, it is as follows. Figure 5 As shown in part (b).

[0136] Figure 5 In part (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 5 In part (b), the left side shows the filter tip of Comparative Example 1 after heating, and the right side shows the filter tip of Example 1 after heating.

[0137] Reference Figure 5 It can be confirmed that the shape of the cellulose acetate filter tip in Comparative Example 1 before and after heating is significantly different, and it melts upon heating, leaving no substantial shape. On the other hand, it can be confirmed that the shape of the lyocell filter tip in Example 1 before and after heating is substantially similar, and it only produces some soot after heating. This confirms that cellulose acetate is a fiber with an amorphous structure, which leads to complete melting due to its weak heat resistance, while lyocell fiber has high heat resistance.

[0138] Example 2 and Comparative Example 2 Tobacco particles were filled into a lyocell tow with a single fineness of 3.33 dtex (denier single count of 3.0) and a total fineness of 3889 tex (total denier of 35000). The lyocell tow was then wrapped with paper rolls, and tobacco particles and a lyocell filter tip with a length of 84 mm were manufactured according to the conditions shown in Example 2 of Table 2. A plasticizer was added to a cellulose acetate tow with a single fineness of 3.00 dtex (denier single count of 2.7) and a total fineness of 3889 tex (total denier of 35000). The cellulose acetate tow was then wrapped with paper rolls, and a cellulose acetate filter tip with a length of 84 mm was manufactured according to the conditions shown in Comparative Example 2 of Table 2. The packaging material used in manufacturing the filter tip was a paper roll with a basis weight of 75 gsm.

[0139] Table 2

[0140] Experimental Example 2. Evaluation based on the physical properties of filter tip materials filled with media substrate. Next, the Lyocell filter tip of Example 2 and the cellulose acetate filter tip of Comparative Example 2 were cut to a length of 15 mm, and then manufactured as follows: Figure 4 The smoking product shown is 3. In particular, such as... Figure 4 As shown in smoking product 3, a heated cigarette (smoking product) was manufactured having a front plug with a length of 7 mm, a cigarette stick of Example 2 and Comparative Example 2, a first section including a paper tube filter with a length of 12 mm and an inner diameter of 6 mm, and a second section with a length of 14 mm and made of cellulose acetate.

[0141] To analyze the material deformation caused by the heat generated during heating of the tobacco stick in the smoking product, the tobacco sticks of the smoking products according to Example 2 and Comparative Example 2 were externally heated in a smoking chamber (specifically, a temperature of approximately 21.9°C and a relative humidity of 64.3%) with an internal temperature of approximately 22±2°C and an internal relative humidity of approximately 60±5%, at a heating temperature of 190°C to 280°C (e.g., 250°C). The tobacco sticks before and after heating were then decomposed, and photographs are shown below. Figure 6 middle.

[0142] On the other hand, Figure 6 middle, Figure 6 Part (a) consists of photographs of the decomposed cigarette sticks of Comparative Example 2 and Example 2 before heating, wherein... Figure 6 The left side of part (a) shows the cigarette stick of Comparative Example 2 before heating. Figure 6 The right side of part (a) shows the heated tobacco stick of Example 2. Furthermore, in Figure 6 middle, Figure 6Part (b) consists of photographs of the decomposed cigarette sticks of Comparative Example 2 and Example 2 after heating, wherein... Figure 6 The left side of part (b) shows the cigarette stick of Comparative Example 2 before heating. Figure 6 The right side of part (b) is the heated tobacco stick of Example 2.

[0143] exist Figure 6 In the middle, refer to Figure 6 Part (a) confirms that Comparative Example 2 (a cigarette stick containing cellulose acetate) and Example 2 (a cigarette stick containing lyocell) are substantially identical in appearance before heating.

[0144] exist Figure 6 In the middle, refer to Figure 6 Part (b) confirms that after heating (i.e., heating at a temperature of 190°C to 280°C), the cigarette stick of Comparative Example 2 underwent significant shrinkage due to the melting and fixation of the cellulose acetate tow. It can be confirmed that the cellulose acetate material shrinks and melts due to the heat applied to the cigarette stick during heating.

[0145] On the other hand, referring to part (b) of FIG7, it can be confirmed that after heating (i.e., heating at a temperature of 190°C to 280°C), in the case of Example 2, although soot caused by heating was generated, it maintained a shape roughly similar to that before heating. Furthermore, it can be confirmed that in Comparative Example 2 (left side), which is composed of cellulose acetate tow, the tobacco particles filled in the tow are agglomerated internally, but in Example 2 (right side), the tobacco particles filled in the tow are stably placed and dispersed throughout the entire area of ​​the lyocell tow.

[0146] On the other hand, compared with cigarette sticks filled with cellulose acetate tow as the medium substrate, cigarette sticks configured to be filled with lyocell tow as the medium substrate can maintain their shape even when heated by a heater, due to the excellent heat resistance of the lyocell tow. This ensures uniform transfer of smoke components during smoking and prevents the cigarette product from breaking or its appearance from deteriorating.

[0147] Experimental Example 4. Flue Gas Composition Analysis A smoking product comprising the tobacco stick of Example 2 and meeting the conditions in Table 3 below was manufactured, and experiments were conducted to analyze the composition of the smoke. In particular, the tobacco stick of the smoking product of Example 2 was heated externally at a temperature of 190°C to 280°C, and the total particulate matter (TPM), nicotine content in the aerosol, and nicotine content in the tobacco stick were measured. The results are shown in Table 4 below.

[0148] In particular, the experiment was conducted using the smoking product according to Example 2 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 by a Cambridge filter (i.e., a Cambridge filter pad, CFP) and analyzed. The total particulate matter (TPM) was determined by measuring the change in weight of the Cambridge filter after smoking compared to the weight before smoking using the smoking device described above. Other components were analyzed by gas chromatography (GC) of the smoke captured in the pad. In addition, the amount of nicotine remaining inside the lyocell filter (especially the lyocell tow) that makes up the cigarette stick was extracted by immersing the cigarette stick in water after smoking, and then analyzed and measured using a GC / MS instrument. In this case, the cigarette stick was immersed in a container of distilled water overnight, and the resulting solution containing the extracted components was then used for GC / MS analysis.

[0149] Table 3

[0150] Table 4

[0151] Referring to Table 4 above, in Example 2, where the cigarette stick is composed of lyocell tow filled with tobacco particles, due to the heat-insulating effect of the lyocell tow and its nicotine retention performance, even after smoking, the nicotine content in the cigarette stick reaches 0.32 mg, which is 40% of the residue compared to before smoking. Therefore, it can be confirmed that its nicotine retention performance is also stable. Although the embodiments of this disclosure have been described above with reference to the accompanying drawings, those skilled in the art will understand that it can be implemented in other specific forms without changing the technical concept or essential technical features of this disclosure. Therefore, it should be understood that the above embodiments are exemplary and non-limiting in all respects. The scope of protection of this disclosure should be interpreted by the appended claims, and all technical ideas within the equivalent scope should be interpreted as falling within the scope of the technical ideas defined by this disclosure.
