[0002] Certain tobacco industry products generate aerosols during use, which are inhaled by the user. For example, tobacco heating devices form aerosols by heating an aerosol-generating substrate, such as tobacco, rather than burning the substrate. Such tobacco industry products generally include a mouthpiece through which the aerosol passes until it reaches the user's mouth. [Overview of the project]

[0009] In the figures described in the present specification, like reference numerals are used to indicate equivalent features, articles or components.

[0010] Figure 1 is a side cross-sectional view of an article 1 for use with a non-combustion aerosol supply system.

[0011] Article 1 comprises a mouthpiece 2 and an aerosol-generating material 3 connected to the mouthpiece 2, in this case a cylindrical rod of tobacco material. The aerosol-generating material 3 delivers an aerosol when heated, for example, in a non-combustion aerosol supply device described herein, for example a non-combustion aerosol supply device comprising a coil that forms a system. In other embodiments, the article 1 may comprise a heat source within the article 1 itself, which forms an aerosol supply system without requiring a separate aerosol supply device.

[0012] The mouthpiece 2 of the article 1 comprises an upstream end 2a adjacent to the aerosol-generating material 3 and a downstream end 2b distal to the aerosol-generating material 3.

[0013] The aerosol-generating material 3, also referred to herein as an aerosol-generating substrate 3, comprises at least one aerosol-former material. In this example, the aerosol-former material is glycerol. In alternative examples, the aerosol-former material may be another material described herein or a combination thereof. It has been found that aerosol-former materials improve the sensory performance of articles by helping to deliver compounds such as flavour compounds from the aerosol-generating material to the consumer. However, a problem associated with adding such aerosol-former materials to aerosol-generating materials in articles for use in non-combustion aerosol supply systems is that when the aerosol-former material is aerosolized upon heating, it may increase the mass of the aerosol delivered by the article, and this increased mass may allow the aerosol to maintain a higher temperature as it passes through the mouthpiece. As the aerosol passes through the mouthpiece, it transfers heat to the mouthpiece, which warms the outer surface of the mouthpiece, including the area that contacts the consumer's lips during use. The temperature of the mouthpiece may be significantly higher than the temperature that consumers are typically accustomed to when smoking, for example higher than conventional cigarettes, which may be an undesirable effect caused by the use of such aerosol-former materials.

[0014] In this example, the mouthpiece includes a body 4 made of a first material. A hollow tubular element 8 and a capsule 15 are embedded within the body 4 of the first material. The hollow tubular element 8 and the capsule 14 are each embedded within the body 4 of the material and are circumferentially surrounded by the material forming the body 4. The body of the first material is encased in a first plug wrap 7.

[0015] In this embodiment, the body 4 is a filter. However, it should be noted that in other embodiments, the body 4 may be configured to act simply as a carrier or support for an embedded object without substantially filtering the inhaled material of article 1.

[0016] The body 4 of the first material is formed from a fibrous material. In this example, the body 4 of the first material is formed from a sheet material 14. The sheet material 14 may be folded to form the body 4 of the material. The body 4 of the material may be formed from a continuous web of the sheet material 14. In this example, the sheet material 14 is assembled in a manner similar to that of a "crepe filter" to form the body 4 of the material. The hollow tubular elements 8 and capsules 15 are embedded within the assembled sheet material 14 and surrounded circumferentially by the assembled sheet material 14 to form the body 4 of the first material.

[0017] In this example, the hollow tubular element 8 is positioned at the longitudinal end of the material body 4 and extends to the longitudinal end of the body. The capsule 15 is positioned downstream of the hollow tubular element 8, and the material body 4 extends beyond the location of the capsule 14 such that the capsule 14 is surrounded by the first material body 4 both circumferentially and longitudinally. Preferably, such a configuration can provide a single component that includes both a cavity for aerosol cooling and an aerosol modifier releasing component, thus resulting in a simplified manufacturing process.

[0018] In this example, the hollow tubular element 8 is formed from multiple layers of paper that are butted together and wound in parallel to form a hollow tube. In this example, the first and second layers of paper are provided in a two-ply tube, but in other examples, three, four, or more layers of paper can be used to form a three-, four, or more-ply tube. Other structures can be used, such as spirally wound layers of paper, cardboard tubes, tubes formed using a papier-mâché type process, or molded or extruded plastic tubes.

[0019] In some embodiments, the air permeability of the wall material of the hollow tubular element 8 is at least 100 coresta units, preferably at least 200, 500, or 1000 coresta units.

[0020] In some examples, the walls of the hollow tubular element 8 are formed from paper having a basis weight in the range of 40 gsm to 100 gsm. For example, paper having a basis weight of 60 gsm to 80 gsm.

[0021] In some cases, the air permeability level of the hollow tubular element 8, when measured on the outside of the material body 4, can be 0.1% to 1%, for example, 0.1%.

[0022] The relatively high permeability of the hollow tubular element 8 was found to increase the amount of heat transferred from the aerosol to the tubular portion, and therefore to lower the temperature of the aerosol. The permeability of the hollow tubular element 8 was also found to increase the amount of moisture transferred from the aerosol to the tubular portion, thereby improving the feel of the aerosol in the user's mouth. The high permeability of the hollow tubular element 8 also means that the air entering the body 4 of the material surrounding the tubular portion can pass through the walls of the hollow tubular element 8 and become an aerosol flow without the need to cut vents through the outer plug wrap(s) and tip paper, the material of the body 4, and all of the tubular elements forming the tubular portion, thereby reducing the complexity of manufacturing.

[0023] In some examples, the sheet material 14 may have notches, such as punched-out areas, to reduce the density of the material body 4. In some examples, the notches may be provided in the portion of the sheet material that forms the portion of the material body 4 surrounding the hollow tubular element 8. Preferably, by providing notches in the sheet material 14 forming this portion of the body, the amount of material that is perforated to provide ventilation within the hollow tubular element 8 can be reduced.

[0024] In some embodiments, perforations may be made in the hollow tubular element 8 before it is embedded in the material body 4 in order to further facilitate the provision of ventilation within the hollow tubular element 8.

[0025] In some embodiments, the permeability of the material of the wall of the hollow tubular element 8 is provided by perforations formed within the material. In some examples, the material is non-porous paper, and the permeability is provided by perforations formed within the material. In other examples, the material is porous paper, and may or may not include perforations. If perforations are provided, they may be provided, for example, as a line of one or more perforations extending through the wall of the hollow tubular element. The perforations may be provided as a band or ring of perforations through the wall of the hollow tubular element. In this case, the perforations may be provided toward the upstream end of the hollow tubular element, for example, about 8 mm to about 2 mm or about 5 mm to about 2 mm from the upstream end of the hollow tubular element.

[0026] Article 1 has a ventilation level through which approximately 75% of the aerosol is drawn in. In alternative embodiments, the article may have a ventilation level through which 20% to 80%, or 30% to 75%, or 50% to 80%, or, for example, 65% to 75%, of the aerosol is drawn in. Ventilation at these levels helps to slow down the flow of aerosol drawn in through the suction port 2, thereby allowing the aerosol to be sufficiently cooled before it reaches the downstream end 2b of the suction port 2. The ventilation is provided directly within the suction port 2 of article 1. In this example, the ventilation is provided within the tubular portion, which has been found to be particularly beneficial in assisting the aerosol generation process. The ventilation is provided by first and second parallel rows of ventilation holes 12, formed in this case as laser perforations, at positions 17.925 mm and 18.625 mm, respectively, from the downstream end 2b of the suction port 2. In this example, these vents 12 penetrate the tip paper 5, the plug wrap 7, and the hollow tubular element 8. In alternative embodiments, ventilation may be provided at other locations within the suction port.

[0027] Alternatively, ventilation may be provided within a portion of an article in which a tubular portion is located, by a single row of vents, for example, by laser drilling. This has been found to result in improved aerosol formation, which is thought to be due to the airflow through the vents being more uniform than that through multiple rows of vents, for a given level of ventilation.

[0028] Aerosol temperature has generally been found to increase with decreasing ventilation levels. However, the relationship between aerosol temperature and ventilation level does not appear to be linear, as variations in ventilation due to manufacturing tolerances, for example, have less effect at lower target ventilation levels. For example, with a ventilation tolerance of ±15% and a target ventilation level of 75%, the aerosol temperature may rise by approximately 6°C at the lower limit of ventilation (60% ventilation). However, at a target ventilation level of 60%, the aerosol temperature may rise by only approximately 3.5°C at the lower limit of ventilation (45% ventilation). Therefore, the target ventilation level of an article can be in the range of 40% to 70%, for example, 45% to 65%. The average ventilation level of at least 20 articles may be 40% to 70%, for example, 45% to 70%, or 51% to 59%.

[0029] In some embodiments, the first plug wrap 7 has a basis weight of less than 50 gsm, more preferably about 20 gsm to 40 gsm. However, it should be noted that the basis weight of the first plug wrap 7 may be higher in order to increase the hardness of the spout. For example, the basis weight of the first plug wrap 7 may be at least 50, 60, 70, 80, 90, or 100 gsm. In some embodiments, the basis weight of the first plug wrap 7 is in the range of 50 to 110 gsm, or in the range of 60 to 100 gsm.

[0030] In some embodiments, the first plug wrap 7 has a basis weight of at least 20 gsm or at least 30 gsm.

[0031] In some embodiments, the first plug wrap 7 has a basis weight of at most 120, 110, or 100 gsm.

[0032] In some embodiments, the first plug wrap 7 has a basis weight in the range of 20 to 120 gsm, preferably in the range of 30 to 100 gsm.

[0033] Preferably, the first plug wrap 7 has a thickness of 30 μm to 60 μm, more preferably 35 μm to 45 μm. However, it should be noted that the thickness and weight of the first plug wrap 7 may be greater in order to increase the hardness of the mouthpiece. In some embodiments, for example, the thickness of the first plug wrap 7 may be at least 40, 50, 60, 70, 80, 90, or 100 microns. In some embodiments, the thickness of the first plug wrap 7 is in the range of 40 to 120 microns, or in the range of 50 to 100 microns.

[0034] Preferably, the first plug wrap 7 is a non-porous plug wrap having an air permeability of, for example, less than 100 cholesta units, or less than 50 cholesta units. However, in other embodiments, the first plug wrap 7 may be a porous plug wrap having an air permeability of, for example, more than 200 cholesta units.

[0035] In this example, the hollow tubular element 8 defines an air gap within the suction port, which acts as a cooling segment. The air gap provides a chamber through which heated volatile components generated by the aerosol-generating material 3 flow. The hollow tubular element 8 is hollow to provide a chamber for aerosol accumulation, but is rigid enough to withstand axial compressive forces and bending moments that may occur during manufacturing and while the article 1 is in use. The hollow tubular element 8 provides a physical displacement between the aerosol-generating material 3 and the downstream portion of the suction port 2. The physical displacement provided by the hollow tubular element 8 provides a thermal gradient over the length of the body 4 of the first material.

[0036] Preferably, the internal volume of the hollow tubular element 8 is 100 mm 3Larger than this. It has been found that by providing a cavity of at least this volume, improved aerosol formation is possible. Such a cavity size provides sufficient space within the mouthpiece 2 to allow the heated volatile components to cool, and thus allows the aerosol-generating material 3 to be exposed to a higher temperature than otherwise, which could otherwise result in an excessively warm aerosol. More preferably, the mouthpiece 2 is 120 mm 3 Larger than that, even more preferably 150mm 3 It features a cavity with a larger internal volume, allowing for further improvement of aerosols. In some examples, the internal cavity is approximately 110 mm 3 ~600mm 3 Preferably about 120 mm 3 ~approximately 500mm 3 It has a volume of approximately 250 mm. In this example, the internal cavity formed by the tubular element 8 is approximately 250 mm. 3 It has a volume of the above. Alternatively, if one of the tubular elements is arranged to provide a cooling segment, that tubular element preferably has the internal volume as described above.

[0037] The cavity may be configured to provide a temperature difference of at least 40 degrees Celsius between the heated volatile components entering the first upstream end of the cavity and the heated volatile components exiting the second downstream end of the cavity. Preferably, the cavity may be configured to provide a temperature difference of at least 60 degrees Celsius, preferably at least 80 degrees Celsius, and more preferably at least 100 degrees Celsius between the heated volatile components entering the first upstream end of the cavity and the heated volatile components exiting the second downstream end of the cavity. This temperature difference along the length of the cavity can protect temperature-sensitive elements at the mouthpiece downstream of the cavity from the high temperature of the aerosol-generating material 3 when the aerosol-generating material 3 is heated.

[0038] Preferably, the length of the hollow tubular element 8 is less than about 50 mm. More preferably, the length of the hollow tubular element 8 is less than about 40 mm. Even more preferably, the length of the hollow tubular element 8 is less than about 35 mm. In addition, or alternatively, the length of the hollow tubular element 8 is preferably at least about 10 mm. Preferably, the length of the hollow tubular element 8 is at least about 15 mm.

[0039] In some preferred embodiments, the length of the hollow tubular element 8 is about 15 mm to about 35 mm, more preferably about 16 mm to about 30 mm, even more preferably about 18 mm to about 25 mm, and most preferably about 23 mm. In this example, the length of the hollow tubular element 8 is 23 mm.

[0040] In some embodiments, the hollow tubular element 8 preferably has a wall thickness of at least about 50 μm to a maximum of about 1 mm, preferably 50 μm to 500 μm, and more preferably 60 μm to 130 μm. In this example, the wall thickness of the hollow tubular element 8 is about 130 μm. The “wall thickness” of the tubular element corresponds to the radial thickness of the wall of the tubular element and does not include the surrounding material in which the tubular element is embedded. This can be measured, for example, using a caliper.

[0041] In some embodiments, the wall thickness of the hollow tubular element 8 is at least 50 microns, preferably at least 75, 80, 85, 90, 95, 100, or 105 microns. In some embodiments, the wall thickness of the tubular element is at least 100 or 110 microns.

[0042] In some embodiments, the wall thickness of the hollow tubular element 8 is less than 1000 microns, preferably less than 500 microns.

[0043] The portion of the material body 4 surrounding the hollow tubular element 8 may have a diameter of 1 mm to 4 mm. The portion of the material body 4 surrounding the hollow tubular element 8 and enclosed by the first plug wrap 7 effectively forms a tubular portion with a wall thickness of approximately 1 mm to approximately 4 mm.

[0044] The combined thickness of the hollow tubular element 8 and the surrounding material body 4 means that the tubular portion formed by the hollow tubular element 8 embedded within the material body 4 has a greater thermal mass. This has been found to help lower the temperature of the aerosol passing through the tubular portion and reduce the surface temperature of the mouthpiece downstream of the tubular portion. It is thought that the greater the thermal mass of the tubular portion, the more heat it can absorb from the aerosol compared to a tubular portion with a thinner wall thickness. Increasing the thickness of the tubular portion guides the aerosol towards the center of the mouthpiece so that less heat from the aerosol is transferred to the outer parts of the mouthpiece, such as the outer parts of the material body.

[0045] Capsule 15 may include a destructible capsule, such as a capsule having a solid, fragile shell surrounding a liquid payload. In this example, a single capsule 15 is used. Capsule 15 is completely embedded within the material body 4. In other examples, multiple destructible capsules, such as two, three, or more, may be arranged within the material body 4. The length of the material body 4 may be increased to accommodate the required number of capsules. In examples where multiple capsules are used, the individual capsules may be identical to one another, or they may differ from one another in size and / or capsule payload.

[0046] The capsule 15 has a core-shell structure. In other words, the capsule 15 includes a shell that encloses a liquid drug, for example, a flavoring or other drug which may be one of the flavorings or aerosol modifiers described herein. The capsule shell can be broken by the user to release the flavoring or other drug into the material body 4. The first plug wrap 7 may include a barrier coating to make the material of the plug wrap substantially impermeable to the liquid payload of the capsule 15.

[0047] In this example, capsule 15 is spherical and has a diameter of approximately 3 mm. In other examples, other shapes and sizes of capsules may be used. For example, capsules may have a diameter of less than 4 mm, or less than 3.5 mm, or less than 3.25 mm. In alternative embodiments, capsules may have a diameter greater than approximately 3.25 mm, for example greater than 3.5 mm, or greater than 4 mm. The total weight of capsule 15 may range from approximately 10 mg to approximately 50 mg.

[0048] In this example, the capsule 15 is located within the material body 4 downstream of the hollow tubular element 8. In this example, the capsule 15 is positioned so that its center is 5 mm from the proximal end of the hollow tubular element 8. Alternatively, the capsule may be positioned so that the hollow tubular element 8 and the capsule 15 are separated by a gap of 1 mm to 30 mm, or 1.5 mm to 20 mm, or 2 mm to 15 mm, or 3 mm to 10 mm. In this example, the center of the capsule is positioned 12 mm from the downstream end of the mouthpiece 2b. By providing the capsule in this position, the volatility of the capsule's contents is improved because the capsule is close to the aerosol-generating section of the article that is heated during use, while at the same time being far enough away from the aerosol-generating section that is inserted into the aerosol supply system during use, allowing the user to easily access and burst the capsule with their finger.

[0049] Preferably, the mouthpiece 2' is configured such that the capsule 15 and the vent hole 12 are offset from each other in the longitudinal direction within the mouthpiece 2'.

[0050] The material body 4 can be manufactured using a CU-20 filter manufacturing machine manufactured by Decouflé (trademark). However, those skilled in the art will understand that other machines may be used to manufacture the first material body 4.

[0051] In some embodiments, the sheet material 14 has a width of at least 60 mm, preferably at least 70, 80, 90, 100, 110, or 120 mm.

[0052] In some embodiments, the sheet material 14 has a width of at most 240 mm, preferably at most 230, 220, 210, 200, 190, 180, 170, 160, or 150 mm.

[0053] In some embodiments, the sheet material 14 has a width of less than 180 mm, preferably less than 170, 160, 150, 140, or 130 mm.

[0054] In some embodiments, the sheet material 14 has a width in the range of 60 to 240 mm, preferably in the range of 80 to 240 mm, 90 to 200 mm, or 100 to 170 mm.

[0055] In this example, the sheet material 14 contains cellulose. In this example, the sheet material 14 is paper. However, the sheet material 14 may additionally or alternatively contain different materials. For example, in some embodiments, the sheet material 14 contains reconstituted tobacco formed on the sheet material 14, which is arranged to form the body 4 of the material. The reconstituted tobacco contains cellulose. The reconstituted tobacco may optionally be paper reconstituted tobacco. In other embodiments, the sheet material 14 contains different materials, such as cotton, tobacco, lyocell, polyvinyl alcohol (PVOH), polylactic acid (PLA), poly(ε-caprolactone) (PCL), poly(1-4-butanediol succinate) (PBS), poly(butylene adipate-co-terephthalate) (PBAT), starch-based materials, aliphatic polyester materials, polysaccharide polymers, and / or woven or nonwoven materials. The sheet material 14 may be biodegradable. In one embodiment, the sheet material 14 may be non-plastic or plastic. In some embodiments, the sheet material 14 does not contain cellulose acetate.

[0056] Biodegradability can be measured according to the procedure described in ISO 14855.

[0057] The tubular elements 8, 11, 4a, and 4b described herein, as well as the material body 4, can achieve more than 50% biodegradation in 30 days when exposed to either freshwater or seawater.

[0058] In one embodiment, the sheet material 14 includes paper having a basis weight in the range of 15 to 80 gsm, preferably in the range of 20 to 50 gsm.

[0059] In some embodiments, the sheet material 14 has a basis weight of at least 15 gsm, preferably at least 20 gsm, 25 gsm, 30 gsm, 35 gsm, 40 gsm, 45 gsm, 50 gsm, 55 gsm, or 60 gsm.

[0060] In some embodiments, the sheet material 14 has a basis weight of 100 gsm or less, preferably 90 gsm or less, 80 gsm or less, 70 gsm or less, 60 gsm or less, 50 gsm or less, or 40 gsm or less, or 30 gsm or less. In some embodiments, the basis weight of the sheet material 14 is 20 gsm or less.

[0061] In some embodiments, the sheet material 14 has a basis weight in the range of 20 to 100 gsm, preferably in the range of 25 to 80 gsm or 30 to 65 gsm.

[0062] In this example, the sheet material 14 is crimped before being placed within the material body 4. For example, the sheet material 14 may be passed through a pair of crimping rollers. In this example, the first material body 4 includes the crimped sheet material 14, which is formed having a crimp pattern comprising a series of substantially parallel ridges and grooves. Crimping can make it easier to gather the sheet material 14 together to form the material body 4. Crimping can also increase the length of the sheet material 14 that can be used to form a material body 4 of a particular volume. By increasing the amount of sheet material 14 within the material body 4, the surface area of ​​the sheet material in contact with aerosols passing through the material body 4 can be increased, and therefore the amount of moisture absorbed from the aerosols by the sheet material 14 can be increased.

[0063] It may be desirable to form different parts of the material body 4 from different amounts of sheet material, which can be achieved by applying different levels of crimping to the sheet material 14 on which the parts are formed. For example, it may be desirable to form the longitudinal ends of the body 4 from longer lengths of sheet material, thereby resulting in a denser arrangement of sheet material, and the longitudinal ends of the body 4, when viewed from the longitudinal ends, appear to consumers more similar to conventional filter elements and, additionally or alternatively, have higher rigidity. Therefore, it may be advantageous to apply a greater amount of crimping to the sheet material 14 forming the longitudinal ends of the body than to the longitudinal central portion of the body. Similarly, if a less dense arrangement of sheet material is desired, it may be advantageous to form parts of the body 4 from shorter lengths of sheet material. For example, if an object is embedded within the body 4, it may be desirable to apply less crimping to the sheet material 14 forming the longitudinal portion of the body on which the object is embedded, in order to lower the density of the sheet material 14 around the embedded object. Such a configuration effectively prevents the pressure drop in the longitudinal portion of the main body from becoming undesirably high.

[0064] The level of crimping applied to the sheet material can contribute to the hardness of the body formed from the sheet material. Preferably, the hardness of the body of the material can be varied along the length of the body by changing the crimp coefficient applied to the sheet material 14 on which the body of the material is formed. For example, a portion of the body of the material formed from a sheet material with a higher level of crimping may have a hardness of about 88% to 92%. A portion of the body of the material with a hardness of 88% to 92% may preferably be formed at the distal end of the body to improve the appearance of the body as seen from that end, and to provide improved stability to the longitudinal end portion of the component. Similarly, other portions of the body may be formed from a sheet material with a lower level of crimping and may have a hardness of at least 80%.

[0065] In this example, the average spacing between adjacent ridges in the sheet material 14 is greater than approximately 0.3 mm. Also, in this example, the crimp amplitude is less than approximately 0.7 mm.

[0066] The crimp amplitude (also known as the "crimping coefficient") refers to the depth of the grooves formed by crimping within the sheet material 14 that forms the main body. That is, as shown in Figure 1B, crimping the sheet material 14 creates a number of peaks and valleys within the sheet material 14 when viewed from a first side of the sheet material 14, and the crimp amplitude "A" is the depth of the valleys measured from those peaks. The crimping can form a "zigzag" shape or another shape. In some examples, adjacent grooves in the crimped sheet material 14 are spaced apart at a distance of 0.3 to 2 mm, preferably 0.4 to 1 mm, or have a pitch "P". In some embodiments, adjacent grooves in the crimped sheet material are spaced apart at a distance of 0.1 to 3 mm, preferably 0.2 to 2 mm. In some embodiments, adjacent grooves in the crimped sheet material 10 are spaced apart at a distance of at least 0.1 mm, preferably at least 0.2, 0.5, 0.7, 1, 1.5, 2, 2.5, or 3 mm. In some embodiments, adjacent grooves in the crimped sheet material are separated by a distance of at most 3 mm, preferably at most 2.5, 2, 1, 1.5, 0.7, 0.5, 0.2, or 0.1 mm.

[0067] For example, the sheet material 14 may have crimps with a crimp amplitude of less than 500 μm and crimps with a spacing between peaks (or valleys) of at least 300 μm, at least 400 μm, or at least 500 μm.

[0068] In some embodiments, the sheet material 14 is heated when it is crimped. For example, the sheet material 14 may be passed between crimping rollers, one or both of which are heated. For example, one or both of the rollers may be heated to a temperature of up to 100 degrees Celsius, for example, 50 degrees Celsius or 60 degrees Celsius. The amount of pressure applied to the sheet material as it passes between the rollers may also vary, for example, between X and Y. A higher level of crimping can be achieved by heating the rollers or by applying a higher level of pressure to the sheet material.

[0069] It has been found that sheet material 14, for example paper, advantageously having the aforementioned crimp pitch and / or amplitude exhibits improved performance when used as a component of an aerosol supply system. In particular, these relatively low levels of crimp pitch and amplitude surprisingly result in a body of material or a portion of a body of material having a lower pressure drop compared to a body or a portion of a body formed from sheet material 14 having higher levels of crimping.

[0070] In any of these examples, the average density of the body of material may be from about 0.1 to about 0.25 mg / mm 3 . The density of the body of material can be measured by separating the body from the article and surrounding plug wrap and / or tipping paper, removing embedded objects, but including any additives added to the sheet material 14. Density can be calculated as tightness based on the weight of the sheet material 14 and any additives added to the sheet material 14, and the total volume occupied by the sheet material 14. For example, the total volume of the body of material 4 measured inside the plug wrap 7.

[0071] In this example, the density of the body of material 4 is about 0.19 mg / mm 3 . In some embodiments, the body 4 has a density of at least 0.1 mg / mm3, 0.12 mg / mm3, or 0.15 mg / mm 3 . Alternatively or additionally, the body of material 4 has a density of less than about 0.3 mg / mm 3 , less than about 0.25 mg / mm 3 , less than about 0.22 mg / mm 3 , and may have a density of less than that. Advantageously, the density of the body of material is from about 0.15 mg / mm 3 to about 0.25 mg / mm 3This is possible. As described above, different parts of the material body 4 may have different densities depending on the level of crimping and assembling applied to the sheet material 14 that forms the part. These values ​​include any additives contained in the material body 4. Before being crimped and formed into the material body, the sheet material 14 has a density of approximately 0.2 to 0.5 mg / mm 3 For example, approximately 0.25, 0.30, or 0.35 mg / mm³ 3 It may have a density of .

[0072] The given dimensions of the sheet material 14 refer to the size of the sheet material before crimping or gathering to form the body of the material. The dimensions of the sheet material 14 can be measured by stretching the sheet material 14 to the extent that no visible crimps remain.

[0073] In this example, the sheet material 14 that forms the main body 4 of the material in which the tubular element 8 is embedded is crimped to a lower level, while the sheet material 14 that forms the distal end of the main body 4 is crimped to a higher level.

[0074] In some embodiments, the sheet material 14 is crimped to a crimp amplitude of at least 0.1 mm, preferably at least 0.3 mm, 0.4 mm, or 0.5 mm.

[0075] In some embodiments, the sheet material 14 is crimped to a crimp amplitude of at most 1 mm, preferably at most 0.8 mm, 0.6 mm, or 0.5 mm.

[0076] In some embodiments, the sheet material 14 comprises at least one slit extending substantially perpendicular to the longitudinal axis of the body 4. The at least one slit is positioned such that, when the sheet material 14 is assembled to the body 4, the slit forms an inner edge within the body 4 that at least partially defines the boundary of the space enclosing the embedded object, allowing the sheet material 14 on the first side (e.g., the downstream side) of the object embedded in the body, such as a hollow tubular element 8, to be brought together. For example, the sheet material 14 may comprise three slits such that one slit is positioned at the downstream end of the hollow tubular element 8 and other slits are positioned on both sides of the capsule 15.

[0077] The inner edge formed by the slit causes the sheet material 14 to be gathered together on one side of the embedded object, defining the boundary at least partially or completely, thereby preventing the object from moving out of the first end of the space in which it is embedded. This improves the positioning of the object embedded in the body 4. In addition, because the sheet material 14 is gathered together, it helps to conceal the embedded object when viewed from the longitudinal end of the body 4, thereby improving the aesthetics of the suction port 2. Preferably, the slit achieves these advantages without requiring the provision of a separate component, such as a cellulose acetate plug, downstream of the embedded object or downstream of the body 4.

[0078] In some examples, the aerosol-generating material 3 described herein is a first aerosol-generating material, and the hollow tubular element 8 may include a second aerosol-generating material. In one example, the inner wall of the tubular element 8 includes the second aerosol-generating material. For example, the second aerosol-generating material may be disposed on the inner surface of the hollow tubular element 8.

[0079] The second aerosol-generating material comprises at least one aerosol-forming agent material and may also comprise at least one aerosol modifier or other sensory material. The aerosol-forming agent material and / or aerosol modifier may be any aerosol-forming agent material or aerosol modifier described herein, or a combination thereof.

[0080] As the aerosol generated from the aerosol-generating material 3, referred to herein as the first aerosol, is drawn in through the hollow tubular element 8 of the mouthpiece, the heat from the first aerosol may aerosolize the aerosol-forming material of the second aerosol-generating material to form the second aerosol. The second aerosol may contain flavorings that are additional to or complementary to the flavor of the first aerosol.

[0081] By providing a second aerosol-generating material on the tubular element 8, it may be possible to generate a second aerosol that enhances or complements the flavor or visual appearance of the first aerosol.

[0082] In this example, article 1 has a circumference of approximately 21 mm (i.e., the article is demi-slim format). Preferably, article 1 has a rod of aerosol-generating material having a circumference greater than 19 mm. This has been found to provide a circumference sufficient to generate an improved, sustained aerosol over a typical aerosol-generating session that is preferable for consumers. When the article is heated, heat is transferred through the rod of aerosol-generating material 3, causing the components of the rod to volatilize, and a circumference greater than 19 mm has been found to be particularly effective in generating an aerosol in this manner. Since the article will be heated and release an aerosol, improved heating efficiency can be achieved by using an article with a circumference of less than approximately 23 mm. A rod circumference greater than 19 mm and less than 23 mm is preferred to achieve improved aerosolization by heating while maintaining a suitable product length. In some examples, the rod circumference may be 20 mm to 22 mm, which has been found to provide a good balance between providing effective aerosol delivery and enabling efficient heating on the one hand.

[0083] The outer circumference of the mouthpiece 2 is substantially the same as the outer circumference of the rod of the aerosol-generating material 3, so that there is a smooth transition between these components. In this example, the outer circumference of the mouthpiece 2 is approximately 20.8 mm.

[0084] In some cases, tip paper 5 contains citrates such as sodium citrate or potassium citrate. In such cases, tip paper 5 may have a citrate content of 2% by weight or less, or 1% by weight or less. Reducing the citrate content of tip paper 5 is thought to help mitigate the carbonization effect that may occur during use.

[0085] In this example, the tip paper 5 extends 5 mm over the rod of the aerosol-generating material 3, but alternatively, it may extend 3 mm to 10 mm, or more preferably 4 mm to 6 mm, over the rod 3 to provide a secure attachment between the mouthpiece 2 and the rod 3. The tip paper 5 may have a higher basis weight than the plug wrap used in article 1, e.g., 40 gsm to 80 gsm, more preferably 50 gsm to 70 gsm, 58 gsm in this example. These ranges of basis weight have been found to result in a tip paper with acceptable tensile strength while having enough flexibility to wrap around article 1 and adhere along the longitudinal overlap seams of the paper. The outer circumference of the tip paper 5 is approximately 21 mm when wrapped around the mouthpiece 2.

[0086] The pressure drop or pressure difference (also called draw resistance) across the mouthpiece, for example, the portion of article 1 downstream of the aerosol-generating material 3, is preferably less than about 40 mmH2O. Such a pressure drop has been found to allow sufficient aerosol containing desirable compounds, such as flavor compounds, to pass through the mouthpiece 2 and reach the consumer. More preferably, the pressure drop across the mouthpiece 2 is less than about 20 mmH2O. In some embodiments, particularly improved aerosols have been achieved using mouthpieces 2 having a pressure drop of less than 15 mmH2O, e.g., about 6 mmH2O, about 10 mmH2O, or about 14 mmH2O. Alternatively or additionally, the pressure drop across the mouthpiece may be at least 3 mmH2O, preferably at least 4 mmH2O, and more preferably at least 5 mmH2O. In some embodiments, the pressure drop across the mouthpiece may be about 5 mmH2O to 20 mmH2O, preferably 5 mmH2O to 15 mmH2O. These values ​​allow the aerosol to slow down as it passes through the mouthpiece 2, so that it has time for the aerosol's temperature to decrease before it reaches the downstream end 2b of the mouthpiece 2.

[0087] In this example, the aerosol-generating material 3 is wrapped in packaging material 10. The packaging material 10 may be, for example, paper or paper-backed foil packaging material. In this example, the packaging material 10 is substantially impermeable to air. In alternative embodiments, the packaging material 10 has an air permeability of preferably less than 100 cholesta units, more preferably less than 60 cholesta units. For example, low-air permeability packaging material having an air permeability of less than 100 cholesta units, more preferably less than 60 cholesta units, has been found to result in improved aerosol formation in the aerosol-generating material 3. While we do not wish to be bound by theory, this is assumed to be due to reduced loss of aerosol compounds through the packaging material 10. The air permeability of the packaging material 10 can be measured according to ISO 2965:2009 for determining air permeability of materials used as cigarette paper, filter plug wraps, and filter bonding paper.

[0088] In this embodiment, the packaging material 10 includes aluminum foil. The aluminum foil has been found to be particularly effective in promoting aerosol formation within the aerosol-generating material 3. In this example, the aluminum foil has a metal layer having a thickness of about 6 μm. In this example, the aluminum foil has a paper backing. However, in alternative configurations, the aluminum foil may have other thicknesses, for example, 4 μm to 16 μm. The aluminum foil may also not have a paper backing, but may have a backing formed from another material, for example, to help provide the foil with appropriate tensile strength, or it may not have a backing at all. Metal layers or foils other than aluminum can also be used. The total thickness of the packaging material is preferably 20 μm to 60 μm, more preferably 30 μm to 50 μm, which provides a packaging material with appropriate structural integrity and heat transfer properties. The tension that can be applied to the packaging material before it breaks may exceed 3,000 grams, for example, a force of 3,000 to 10,000 grams, or a force of 3,000 to 4,500 grams.

[0089] In some examples, the packaging material 10 surrounding the aerosol-generating material 3 has a high level of air permeability, for example, more than about 1000 cholesta units, or more than about 1500 cholesta units, or more than about 2000 cholesta units. The air permeability of the packaging material 10 can be measured according to ISO 2965:2009 for determining the air permeability of materials used as cigarette paper, filter plug wraps, and filter bonding paper.

[0090] The packaging material 10 may be formed from a material having a high inherent level of permeability, an inherently porous material, or from a material having any inherent level of permeability, where the final level of permeability is achieved by providing permeable zones or areas in the packaging material 10. By providing permeable packaging material 10, a path is provided for air to enter the article. The packaging material 10 may be permeable such that the amount of air entering through the rod of aerosol-generating material is relatively greater than the amount of air entering the article through the vents 12 in the mouthpiece. An article having this configuration may generate a more flavorful aerosol, which may be more satisfying for the user.

[0091] In this example, the aerosol-forming agent material added to the aerosol-generating substrate 3 comprises 14% by weight of the aerosol-generating substrate 3. Preferably, the aerosol-forming agent material comprises at least 5% by weight, more preferably at least 10% by weight, of the aerosol-generating substrate. Preferably, the aerosol-forming agent material comprises less than 25% by weight, more preferably less than 20% by weight, for example, 10% to 20% by weight, 12% to 18% by weight, or 13% to 16% by weight of the aerosol-generating substrate.

[0092] Preferably, the aerosol generating material 3 is provided as a cylindrical rod of aerosol generating material. Regardless of the form of the aerosol generating material, the aerosol generating material preferably has a length of about 10 mm to 100 mm. In some embodiments, the length of the aerosol generating material is preferably in the range of about 25 mm to 50 mm, more preferably in the range of about 30 mm to 45 mm, and even more preferably about 30 mm to 40 mm.

[0093] In some examples, article 1 may be configured to have a separation (i.e., minimum distance) between the heater of the non-combustible aerosol supply device 100 and the hollow tubular element 8. This prevents the material forming the hollow tubular element 8 from being damaged by heat from the heater.

[0094] The minimum distance between the heater and the hollow tubular element 8 of the non-combustible aerosol supply device 100 may be 3 mm or more. In some examples, the minimum distance between the heater and the hollow tubular element 8 of the non-combustible aerosol supply device 100 may be in the range of 3 mm to 10 mm, for example, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.

[0095] Separation between the heater and the hollow tubular element 8 of the non-combustion aerosol supply device 100 can be achieved, for example, by adjusting the length of the rod of the aerosol generating material 3.

[0096] The volume of the aerosol-generating material 3 provided is approximately 200 mm³. 3 ~Approximately 4300mm 3 Preferably about 500 mm 3 ~1500mm 3 , more comfortably approximately 1000mm 3 ~approximately 1300mm 3 It can vary. For example, about 1000mm 3 ~approximately 1300mm 3 The provision of aerosol-generating materials in these volumes is preferably shown to achieve superior aerosols with excellent visibility and sensory performance compared to those achieved with volumes selected from the lower end of the range.

[0097] The mass of the aerosol-generating material 3 provided may be greater than 200 mg, for example, about 200 mg to 400 mg, preferably about 230 mg to 360 mg, and more preferably about 250 mg to 360 mg. It has been preferably found that providing an aerosol-generating material with a higher mass results in improved sensory performance compared to aerosols generated from tobacco material with a lower mass.

[0098] Preferably, the aerosol-generating material or substrate is formed from a tobacco material described herein that contains tobacco components.

[0099] In the tobacco materials described herein, the tobacco component preferably contains paper-reconstructed tobacco. The tobacco component may also contain loose leaf tobacco, extruded tobacco, and / or band-cast tobacco.

[0100] Aerosol-generating material 3 may include reconstituted tobacco material having a density of less than approximately 700 milligrams per cubic centimeter (mg / cc). Such tobacco material has been found to be particularly effective in providing an aerosol-generating material that can be heated rapidly to release aerosols compared to denser materials. For example, the inventors tested the properties of various aerosol-generating materials, such as band-cast reconstituted tobacco material and paper reconstituted tobacco material, when heated. For each given aerosol-generating material, there is a specific zero heat flow temperature, and while heat is being applied to the material, if the temperature is below this temperature, the net heat flow is endothermic, in other words, more heat enters the material than leaves it, and if the temperature is above this temperature, the net heat flow is exothermic, in other words, more heat leaves the material than enters it. Materials with a density of less than 700 mg / cc had a lower zero heat flow temperature. Since the majority of the heat flow from the material is through aerosol formation, having a lower zero heat flow temperature has a beneficial effect on the time it takes for the aerosol to be first released from the aerosol-generating material. For example, it was found that aerosol-generating materials with a density of less than 700 mg / cc have a zero heat flow temperature of less than 164°C compared to materials with a density of more than 700 mg / cc that have a zero heat flow temperature of more than 164°C.

[0101] The density of the aerosol-generating material also affects the rate at which heat is conducted through the material; lower densities, such as those below 700 mg / cc, allow heat to be conducted more slowly through the material, thus enabling more sustained aerosol release.

[0102] Preferably, the aerosol-generating material 3 comprises a reconstituted tobacco material having a density of less than about 700 mg / cc, such as a paper reconstituted tobacco material. More preferably, the aerosol-generating material 3 comprises a reconstituted tobacco material having a density of less than about 600 mg / cc. Alternatively or additionally, the aerosol-generating material 3 preferably comprises a reconstituted tobacco material having a density of at least 350 mg / cc, which is considered to allow a sufficient amount of heat conduction through the material.

[0103] The tobacco material may be provided in the form of cut rag tobacco. The cut rag tobacco may have a cut width of at least 15 cuts / inch (approximately 5.9 cuts / cm, corresponding to a cut width of approximately 1.7 mm). Preferably, the cut rag tobacco has a cut width of at least 18 cuts / inch (approximately 7.1 cuts / cm, corresponding to a cut width of approximately 1.4 mm), and more preferably at least 20 cuts / inch (approximately 7.9 cuts / cm, corresponding to a cut width of approximately 1.27 mm). In one example, the cut rag tobacco has a cut width of 22 cuts / inch (approximately 8.7 cuts / cm, corresponding to a cut width of approximately 1.15 mm). Preferably, the cut rag tobacco has a cut width of 40 cuts / inch (approximately 15.7 cuts / cm, corresponding to a cut width of approximately 0.64 mm) or less. Cut widths of 0.5 mm to 2.0 mm, for example, 0.6 mm to 1.5 mm, or 0.6 mm to 1.7 mm, have been found to be preferable tobacco materials, particularly in terms of the surface area-to-volume ratio when heated, as well as the overall density and pressure drop of the base material 3. Cut rag tobacco can be formed from a mixture of forms of tobacco material, such as a mixture of one or more of paper-reconstructed tobacco, leaf tobacco, extruded tobacco, and band-cast tobacco. Preferably, the tobacco material includes paper-reconstructed tobacco, or a mixture of paper-reconstructed tobacco and leaf tobacco.

[0104] In the tobacco materials described herein, the tobacco material may contain filler components. Filler components are generally non-tobacco components, i.e., components that do not contain raw materials derived from tobacco. Filler components may be non-tobacco fibers such as wood fibers or pulp or wheat fibers. Filler components may also be inorganic materials such as chalk, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, or magnesium carbonate. Filler components may also be non-tobacco cast materials or non-tobacco extruded materials. Filler components may be present in an amount of 0 to 20% by weight of the tobacco material, or in an amount of 1 to 10% by weight of the composition. In some embodiments, filler components are absent.

[0105] In the tobacco materials described herein, the tobacco material contains an aerosol-forming agent material. In this context, “aerosol-forming agent material” is an agent that promotes aerosol formation. Aerosol-forming agent materials can promote aerosol formation by promoting the initial vaporization and / or condensation of gas into inhalable solid and / or liquid aerosols. In some embodiments, aerosol-forming agent materials can improve the delivery of flavor from the aerosol-forming material. In general, any suitable aerosol-forming agent material, including those described herein, may be included in the aerosol-forming material of the present invention. Other suitable aerosol-forming agent materials include, but are not limited to, sorbitol, glycerol, polyols such as glycols such as propylene glycol or triethylene glycol, non-polyols such as monohydric alcohols, high-boiling hydrocarbons, acids such as lactic acid, glycerol derivatives, esters such as diacetin, triacetin, triethylene glycol diacetate, triethyl citrate, or myristic acid including ethyl myristate and isopropyl myristate, and aliphatic carboxylic acid esters such as methyl stearate, dimethyl dodecanediate, and dimethyl tetradecanediate. In some embodiments, the aerosol-forming agent material may be glycerol, propylene glycol, or a mixture of glycerol and propylene glycol. Glycerol may be present in an amount of 10-20% by weight of the tobacco material, for example, 13-16% by weight of the composition, or about 14% or 15% by weight of the composition. Propylene glycol, if present, may be present in an amount of 0.1-0.3% by weight of the composition.

[0106] Aerosol-forming materials may be included in any component of the tobacco material, for example, in any tobacco component and / or in the filler component, if present. Alternatively or additionally, aerosol-forming materials may be added separately to the tobacco material. In any case, the total amount of aerosol-forming materials in the tobacco material may be as defined herein.

[0107] The tobacco material may contain 10% to 90% by weight of tobacco leaves, and the aerosol-forming agent material is provided in an amount of up to approximately 10% by weight of tobacco leaves. To achieve an overall level of 10% to 20% by weight of the aerosol-forming agent material in the tobacco material, it has been preferably found that it can be added in a higher weight percentage relative to other components of the tobacco material, such as the reconstituted tobacco material.

[0108] The tobacco materials described herein contain nicotine. The nicotine content is 0.5 to 1.75% by weight relative to the tobacco material, and may be, for example, 0.8 to 1.5% by weight relative to the tobacco material. Additionally or alternatively, the tobacco material contains 10% to 90% by weight of tobacco leaves with a nicotine content of more than 1.5% by weight of tobacco leaves. It has been preferably found that using tobacco leaves with a nicotine content of more than 1.5% in combination with a lower nicotine base material such as paper reconstituted cigarettes provides a tobacco material with a more appropriate nicotine level but with superior sensory performance than using paper reconstituted cigarettes alone. Tobacco leaves, for example, cut rag cigarettes, may have a nicotine content of, for example, 1.5% to 5% by weight of tobacco leaves.

[0109] The tobacco materials described herein may contain aerosol modifiers such as any of the flavors described herein. In one embodiment, the tobacco material contains menthol to form a menthol-containing article. The tobacco material may contain 3 mg to 20 mg of menthol, preferably 5 mg to 18 mg, more preferably 8 mg to 16 mg of menthol. In this example, the tobacco material contains 16 mg of menthol. The tobacco material may contain 2% to 8% by weight of menthol, preferably 3% to 7% by weight of menthol, more preferably 4% to 5.5% by weight of menthol. In one embodiment, the tobacco material contains 4.7% by weight of menthol. Such high levels of menthol filling can be achieved, for example, by using a high percentage of reconstituted tobacco material exceeding 50% by weight of the tobacco material. Alternatively or additionally, the level of menthol filling can be increased by using a large amount of aerosol-generating material, such as tobacco material, which can be achieved, for example, when aerosol-generating material such as more than about 500 mm³ or preferably more than about 1000 mm³ of tobacco material is used.

[0110] In the compositions described herein, where amounts are given in weight percent, to avoid misunderstanding, this refers to a dry weight basis unless otherwise indicated. Therefore, any water that may be present in the tobacco material or any of its components is completely disregarded for the purpose of determining the weight percent. The water content of the tobacco materials described herein can vary, for example, from 5 to 15% by weight. The water content of the tobacco materials described herein can vary, for example, depending on the temperature, pressure, and humidity conditions under which the composition is maintained. The water content can be determined by Karl Fischer analysis, as is known to those skilled in the art. On the other hand, to avoid misunderstanding, any components other than water are included in the weight of the tobacco material, even if the aerosol-forming agent material is a liquid-phase component such as glycerol or propylene glycol. However, if the aerosol-forming agent material is provided in the tobacco component of the tobacco material or in addition to the filler component of the tobacco material (if present), instead of being added separately to the tobacco material, the aerosol-forming agent material is not included in the weight of the tobacco component or filler component, but is included in the weight of the "aerosol-forming agent material" in weight percent as defined herein. All other components present in tobacco are included in the weight of the tobacco component, even if they are of non-tobacco origin (for example, non-tobacco fibers in the case of reconstituted cigarettes).

[0111] In one embodiment, the tobacco material comprises tobacco components as defined herein and aerosol-forming agent materials as defined herein. In one embodiment, the tobacco material essentially consists of tobacco components as defined herein and aerosol-forming agent materials as defined herein. In one embodiment, the tobacco material consists of tobacco components as defined herein and aerosol-forming agent materials as defined herein.

[0112] Paper-reconstructed tobacco is present in the tobacco components of the tobacco material described herein in an amount of 10% to 100% by weight of the tobacco components. In embodiments, paper-reconstructed tobacco is present in an amount of 10% to 80% by weight, or 20% to 70% by weight, of the tobacco components. In further embodiments, the tobacco components consist essentially of or comprise paper-reconstructed tobacco. In preferred embodiments, leaf tobacco is present in the tobacco components of the tobacco material in an amount of at least 10% by weight of the tobacco components. For example, leaf tobacco may be present in an amount of at least 10% by weight of the tobacco components, while the remainder of the tobacco components includes paper-reconstructed tobacco, band-cast reconstructed tobacco, or a combination of band-cast reconstructed tobacco and another form of tobacco such as tobacco granules.

[0113] Paper-reconstructed tobacco refers to tobacco material formed by a process in which tobacco raw materials are extracted with a solvent to obtain an extract of soluble substances and a residue containing fibrous material, and then the extract (usually after concentration and optionally after further processing) is recombined with fibrous material from the residue (usually after purification of the fibrous material and optionally with the addition of some non-tobacco fibers) by depositing the extract onto the fibrous material. The recombination process is similar to the process of making paper.

[0114] Paper-reconstructed cigarettes can be any type of paper-reconstructed cigarette known in the art. In certain embodiments, paper-reconstructed cigarettes are made from raw materials comprising one or more of tobacco strips, tobacco stalks, and whole tobacco leaves. In further embodiments, paper-reconstructed cigarettes are made from raw materials comprising tobacco strips and / or whole tobacco leaves, as well as tobacco stalks. However, in other embodiments, scraps, fine powder, and wineing may be used as alternative or additional raw materials.

[0115] Paper-reconstructed tobacco for use in the tobacco materials described herein may be prepared by methods known to those skilled in the art for preparing paper-reconstructed tobacco.

[0116] Figure 2 is a side cross-sectional view of article 1' for use with a non-combustible aerosol supply system. Article 1' comprises a mouthpiece 2' which is substantially the same as mouthpiece 2, except that the material body 4 is replaced by a material body 4' further comprising a second tubular element 11 at the downstream end of the body 4'. The second tubular element 11 extends to the mouth end of the material body 4'.

[0117] In this example, the hollow tubular element 8 and the second hollow tubular element 11 are separated by a gap of 10 mm. Alternatively, the first and second hollow tubular elements 8 and 11 are separated by gaps of other distances, for example, 5 mm to 15 mm, or 6 mm to 12 mm, or approximately 6 mm, approximately 7 mm, approximately 8 mm, or approximately 9 mm. The body 4' of the material extends within and across the gap. In this example, the capsule 15 is embedded within the body 4' of the material in the gap between the first and second hollow tubular elements 8 and 11.

[0118] In this example, the sheet material 14 forming the main body 4' has two slits positioned at the downstream and upstream ends of the first and second hollow tubular elements 8 and 11, respectively. The slits are positioned so that when the sheet material 14 is assembled to the main body 4', the slits release the sheet material 14 between the slits and extend into the gap between the first and second hollow tubular elements 8 and 11. Additionally or alternatively, the sheet material 14 may have one or more slits positioned on either side or both sides of the embedded capsule 15.

[0119] In this example, the first hollow tubular element 8 provides a cavity for aerosol cooling, as described above.

[0120] The second hollow tubular element 11 is embedded within the material body 4' at the downstream end of the material body 4' and extends to the longitudinal end of the body 4'. It has been found that providing the tubular element in this position preferably significantly reduces the temperature of the outer surface of the mouthpiece 2' at the downstream end 2b of the mouthpiece that comes into contact with the consumer's mouth when the article 1' is in use. In addition, it has been found that the use of the tubular portion also significantly reduces the temperature of the outer surface of the mouthpiece 2' even upstream of the tubular portion. While we do not wish to be bound by theory, it is assumed that this is due to the tubular portion guiding the aerosol closer to the center of the mouthpiece 2', and thus reducing heat transfer from the aerosol to the outer surface of the mouthpiece 2'. In addition, it has been found that the material body 4' filling the gap between the first tubular element 4a' and the second hollow tubular element 11 removes moisture from the aerosol generated by the aerosol-generating material 3 as the aerosol passes through the material body 4' of the mouthpiece 2, thereby causing the aerosol to feel cooler in the user's mouth.

[0121] The second hollow tubular element 11 preferably has an inner diameter greater than 3.0 mm. A smaller diameter may result in the aerosol passing through the mouthpiece 2''' and reaching the consumer's mouth increasing beyond the desired rate, causing the aerosol to become excessively warm and reach temperatures above, for example, 40°C or 45°C. More preferably, the second hollow tubular element 11 has an inner diameter greater than 3.1 mm, and even more preferably greater than 3.5 mm or 3.6 mm. In one embodiment, the inner diameter of the second hollow tubular element 11 is about 3.9 mm.

[0122] By forming a mouthpiece that includes a body 4' of material comprising first and second hollow tubular elements 8, 11 embedded at opposing ends of the body 4' of material, a mouthpiece is preferably obtained having a concave mouth end surrounded by a plug wrap of a thinner thickness than typically required for such a structure, and a cavity for aerosol cooling at the upstream end of the mouthpiece, because both cavities are provided by tubular elements embedded in the same body of material, eliminating the need for separate plug wraps and bonding wraps for different components. Not only does this simplify the manufacture of the mouthpiece by reducing the number of components, but it can also be easier to form a ventilation aperture in the body 4' of material at the desired location because the thickness of the plug wrap to be perforated is less. A body 4' of material comprising both first and second hollow tubular elements 8, 11 and a capsule 15 embedded in the body 4' of material between the first and second hollow tubular elements 8, 11 preferably results in a component that has the advantage of being easier to manufacture, as described above in relation to Figure 1.

[0123] In this example, the second hollow tubular element 11 has a thicker wall thickness than the first hollow tubular element 8 and is shorter than the first hollow tubular element 8, such that the cavity at the mouth end 2b of the mouthpiece provided by the second hollow tubular element 11 is smaller than the cavity formed by the first hollow tubular element 8. In other examples, the wall thickness of the hollow tubular element 8 may be thicker than the wall thickness of the second hollow tubular element 11. Preferably, by selecting different wall thicknesses, inner diameters, and / or lengths for the first and second hollow tubular elements 8 and 11, respectively, it becomes possible to optimize the cavities at both ends of the material body 4' for cooling and / or guiding the aerosol through the mouthpiece, as desired, based on the positions of the first and second hollow tubular elements 8 and 11 within the mouthpiece.

[0124] Preferably, the length of the second hollow tubular element 11 is less than about 20 mm. More preferably, the length of the second hollow tubular element 11 is less than about 15 mm. Even more preferably, the length of the second hollow tubular element 11 is less than about 10 mm. In addition, or alternatively, the length of the second hollow tubular element 11 is at least about 5 mm. Preferably, the length of the second hollow tubular element 11 is at least about 6 mm. In some preferred embodiments, the length of the second hollow tubular element 11 is about 5 mm to about 20 mm, more preferably about 6 mm to about 10 mm, even more preferably about 6 mm to about 8 mm, most preferably about 6 mm, 7 mm, or about 8 mm. In this example, the length of the second hollow tubular element 11 is 6 mm.

[0125] In this example, each of the first and second hollow tubular elements 8 and 11 is surrounded by a body 4' of the same outer diameter and thickness.

[0126] As described above, different levels of crimping can be applied to the sheet material 14 that forms different parts of the main body 4' of the material. In this example, the sheet material forming the mouth end portion of the main body 4' into which the second hollow tubular element 11 is embedded is crimped to a higher level than the sheet material 14 forming the part of the main body 4' into which the first hollow tubular element 8 and capsule 15 are embedded. Preferably, by applying a higher level of crimping to the sheet material 14 around the second hollow tubular element 11, a more desirable hardness of the mouthpiece at the mouth end 2b and an improvement in the appearance of the mouthpiece when viewed from the mouth end can be obtained.

[0127] The plug wrap 7 and / or tip paper 5 may include a barrier coating to make the material of the plug wrap and / or tip paper substantially impermeable to the liquid payload of the capsule 15.

[0128] Figure 3 is a side cross-sectional view of article 1'' for use with a non-combustible aerosol supply system. Article 1'' comprises a mouthpiece 2'' including a material body 4''. The material body 4'' is substantially the same as the material body 4', except that the material body 4'' does not have a first hollow tubular element 8 upstream of the capsule 15. In this example, instead, a cooling section 13 is provided upstream of the material body 4'' to provide a cavity for aerosol cooling.

[0129] In this example, the main body 4'' of the material extends approximately 3.5 mm upstream of the capsule 15. Alternatively, the main body 4'' of the material may extend approximately 1 mm upstream of the capsule 15, or approximately 2 mm, 3 mm, 5 mm, 6 mm, 7 mm, 8 mm, or 10 mm upstream of the capsule 15.

[0130] In this example, the capsule 15 is separated from the second hollow tubular element 11 at its opening by a gap of approximately 4.5 mm. Alternatively, the capsule 15 may be separated from the second hollow tubular element 11 by a gap of 0.5 mm to 30 mm, or 1 mm to 20 mm, or 1.5 mm to 15 mm, or 2 mm to 10 mm. For example, the capsule 15 may be separated from the second hollow tubular element 11 by a gap of approximately 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, or 8 mm. The separation of the capsule 15 from the second hollow tubular element 11 may be chosen to provide a suitable amount of material within the material body 4'' to absorb the liquid filler of the capsule 15, and to balance the desired length of the component with the pressure drop.

[0131] As explained in relation to Figure 2, various levels of crimping can be applied to the sheet material 14 that forms the body 4'' of the material. In this example, a higher level of crimping is applied to the sheet material that forms a section of the body 4'' of the material at the mouth end. The body 4'' of the material may have a higher density in the portion closer to the downstream end of the body 4'' than in the portion closer to the upstream end. For example, the portion of the body 4'' of the material within 3 mm from the longitudinal end of the body 4'' may have a higher density than the portion upstream of this 3 mm portion. The portion of the body formed from the sheet material having a higher level of crimping and a higher density than other portions of the body may have a more attractive appearance to consumers. Preferably, such a section may be provided at the longitudinal end of the body 4'', giving the body 4'' an attractive appearance from the longitudinal end to consumers, while the upstream portion of the component may have a lower density to limit the amount of sheet material 14 required to form the body 4'' of the material and to prevent the body 4'' from having an undesirable high pressure drop. The density of a particular section of the body 4'' can be measured by separating the section from the rest of the body and the surrounding plug wrap and / or chip paper (for example, by cutting the body) and removing any embedded material, but not including any additives added to the sheet material 14.

[0132] In this example, the cooling section 13, as described with respect to the hollow tubular element 8, defines an air gap within the inlet that acts as a cooling segment. The air gap provides a chamber through which heated volatile components generated by the aerosol-generating material 3 flow. The cooling section 13 is hollow to provide a chamber for aerosol accumulation, but is rigid enough to withstand axial compressive forces and bending moments that may occur during manufacturing and while the article 1 is in use. The cooling section 13 provides physical displacement between the aerosol-generating material 3 and the downstream portion of the inlet 2.

[0133] Preferably, the internal volume of the cooling section 13 is 100 mm 3Larger than this. It has been found that by providing a cavity of at least this volume, improved aerosol formation is possible. Such a cavity size provides sufficient space within the mouthpiece 2 to allow the heated volatile components to cool, and thus allows the aerosol-generating material 3 to be exposed to a higher temperature than otherwise, which could result in an excessively warm aerosol. More preferably, the mouthpiece 2'' is 120 mm 3 Larger than that, even more preferably 150mm 3 It features a cavity with a larger internal volume, allowing for further improvement of aerosols. In some examples, the internal cavity is approximately 110 mm 3 ~600mm 3 Preferably about 120 mm 3 ~approximately 500mm 3 It has the volume of .

[0134] The cavity may be configured to provide a temperature difference of at least 40 degrees Celsius between the heated volatile components entering the first upstream end of the cavity and the heated volatile components exiting the second downstream end of the cavity. Preferably, the cavity may be configured to provide a temperature difference of at least 60 degrees Celsius, preferably at least 80 degrees Celsius, and more preferably at least 100 degrees Celsius between the heated volatile components entering the first upstream end of the cavity and the heated volatile components exiting the second downstream end of the cavity. This temperature difference along the length of the cavity can protect temperature-sensitive elements at the mouthpiece downstream of the cavity from the high temperature of the aerosol-generating material 3 when the aerosol-generating material 3 is heated.

[0135] Preferably, the length of the cooling section 13 is less than about 50 mm. More preferably, the length of the cooling section 13 is less than about 40 mm. Even more preferably, the length of the cooling section 13 is less than about 35 mm. In addition, or alternatively, the length of the cooling section 13 is preferably at least about 10 mm. Preferably, the length of the cooling section 13 is at least about 15 mm.

[0136] In some preferred embodiments, the length of the cooling section 13 is about 15 mm to about 35 mm, more preferably about 20 mm to about 30 mm, even more preferably about 23 mm to about 27 mm, and most preferably about 25 mm. In this example, the length of the cooling section 13 is 25 mm.

[0137] In this example, the cooling section 13 is formed from multiple layers of paper that are butted together and wound in parallel to form a hollow tube. In this example, the first and second layers of paper are provided in a two-ply tube, but in other examples, three, four, or more layers of paper can be used to form a three-, four, or more-ply tube. Other structures can be used, such as spirally wound layers of paper, cardboard tubes, tubes formed using a papier-mâché type process, or molded or extruded plastic tubes.

[0138] In some embodiments, the cooling section 13 preferably has a wall thickness of at least about 50 μm to a maximum of about 1 mm, preferably 100 μm to 500 μm, and more preferably 100 μm to 150 μm. In this example, the cooling section 13 has a wall thickness of about 150 μm. The “wall thickness” of the tubular element corresponds to the thickness of the wall of the tubular element in the radial direction, excluding the surrounding material in which the tubular element is embedded. This can be measured, for example, using a caliper.

[0139] In some embodiments, the wall thickness of the cooling section 13 is at least 50 microns, preferably at least 75, 80, 85, 90, 95, 100, or 105 microns. In some embodiments, the wall thickness of the tubular element is at least 100 or 110 microns.

[0140] In some embodiments, the wall thickness of the cooling section 13 is less than 1000 microns, preferably less than 500 microns.

[0141] In some embodiments, the permeability of the wall material of the cooling section 13 is at least 100 cholesta units, preferably at least 500 or 1000 cholesta units.

[0142] The relatively high permeability of the cooling section 13 was found to increase the amount of heat transferred from the aerosol to the tubular portion, and therefore to lower the temperature of the aerosol. The permeability of the cooling section 13 was also found to increase the amount of moisture transferred from the aerosol to the tubular portion, thereby improving the feel of the aerosol in the user's mouth. The high permeability of the cooling section 13 also means that the air entering the body 4 of the material surrounding the tubular portion can pass through the walls of the cooling section 13 and become an aerosol flow without the need to cut vents through the outer plug wrap and tip paper, the material of the body 4, and all of the tubular elements forming the tubular portion, thereby reducing manufacturing complexity.

[0143] The cooling section 13 and the material body 4'' are connected by a second plug wrap 9.

[0144] According to this disclosure, “aerosol supply system” includes both combustion-type aerosol supply systems and non-combustion-type aerosol supply systems.

[0145] Figure 4 is a side cross-sectional view of a further article 1''' for use with a non-combustible aerosol supply system. Article 1''' comprises a suction port 2'''' which is substantially the same as suction port 2, except that in this example the hollow tubular element 8 is replaced by tubular elements 4a, 4b. In this example, the tubular elements 4a, 4b form a cavity for aerosol cooling, as described with respect to the hollow tubular element 8. The tubular elements 4a, 4b are embedded within a body 4''' of material and are circumferentially surrounded by the material forming the body 4'''. The tubular elements 4a, 4b may have any preferred specifications, as described with respect to the first and second hollow tubular elements 8, 11. In this example, the tubular elements 4a, 4b have the same specifications. Alternatively, the specifications of tubular element 4a may differ from those of tubular element 4b, for example, to provide a cavity with regions of varying inner diameters or porosity.

[0146] In the examples in Figures 2 and 4, it is optional to provide the capsule 15 within the material bodies 4, 4'''.

[0147] In this example, the first tubular element 4a is positioned at the longitudinal end of the material body 4''' and extends to the longitudinal end of the body. The second tubular element 4b is positioned downstream of the first tubular element 4a, and the material body 4''' extends beyond the second tubular element 4b such that the second tubular element is surrounded by the first material body 4 in both the circumferential and longitudinal directions.

[0148] In this example, the first and second tubular elements 4a and 4b are separated by a gap of approximately 1 mm to effectively form a continuous tubular portion. In embodiments where the first and second tubular elements 4a and 4b are intended to effectively form a continuous tubular portion, the tubular elements may be preferably separated by a gap of 0.5 mm to 6 mm, for example, 1 mm to 3 mm, or 2 mm to 5 mm. In this example, the tubular portion formed by the first and second tubular elements 4a and 4b defines an air gap within the intake that acts as a cooling segment. In this example, the tubular portion comprises first and second tubular elements 4a and 4b, each having a length of 11 mm and separated by a gap of 1 mm.

[0149] In other examples, the hollow tubular element 11 may be similarly formed by first and second tubular elements (not shown).

[0150] According to this disclosure, a “combustion-type” aerosol supply system is a system in which, during use, the aerosol-generating material (or its components) that constitutes the aerosol supply system is burned or incinerated in order to facilitate the delivery of at least one substance to the user.

[0172] In some embodiments, the flavor may include a sensory stimulant, which is intended to achieve somatosensations that are normally chemically induced and perceived by stimulation of the fifth cranial nerve (trigeminal nerve), in addition to or instead of the aroma or taste nerves, and these may include agents that produce heating, cooling, tingling, or numbing effects. A preferred thermal agent may be, but is not limited to, vanillyl ethyl ether, and a preferred cooling agent may be, but is not limited to, eucalyptol or WS-3.

[0173] Aerosol-generating materials are materials that can generate aerosols when heated, irradiated, or given energy in any other way. Aerosol-generating materials can be in the form of solids, liquids, or gels, which may or may not contain active substances and / or flavorings. In some embodiments, aerosol-generating materials may include “amorphous solids,” which may alternatively be referred to as “monolithic solids” (i.e., non-fibrous). In some embodiments, amorphous solids may be dry gels. Amorphous solids are solid materials that can hold some fluid, such as a liquid, within the amorphous solid. In some embodiments, aerosol-generating materials may include, for example, amorphous solids ranging from about 50 wt%, 60 wt%, or 70 wt% to about 90 wt%, 95 wt%, or 100 wt% amorphous solids.

[0174] The aerosol-generating material may comprise one or more active substances and / or flavorings, one or more aerosol-forming materials, and optionally one or more other functional materials.

[0175] The aerosol-forming agent material may contain one or more components capable of forming an aerosol. In some embodiments, the aerosol-forming agent material may contain one or more of the following: glycerin, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, mesoerythritol, ethyl vanillate, ethyl laurate, diethyl suberate, triethyl citrate, triacetin, diacetin mixture, benzyl benzoate, benzyl phenylacetate, tributyline, lauryl acetate, lauric acid, myristic acid, and propylene carbonate.

[0176] One or more other functional materials may include one or more of the following: pH adjusters, colorants, preservatives, binders, fillers, stabilizers, and / or antioxidants.

[0177] The material may be present on or within a support to form a substrate. The support may be, for example, paper, cardboard, cardboard, reconstituted material, plastic material, ceramic material, composite material, glass, metal, or metal alloy, or may comprise these. In some embodiments, the support comprises a susceptor. In some embodiments, the susceptor is embedded within the material. In some alternative embodiments, the susceptor is on one or both sides of the material.

[0178] Consumables are articles comprising or consisting of aerosol-generating material, some or all of which are intended to be consumed during use by the user. Consumables may comprise one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material transfer component, an aerosol-generating area, a housing, packaging material, a mouthpiece, a filter, and / or an aerosol modifier. Consumables may also comprise an aerosol generator, such as a heater, which generates heat during use to cause the aerosol-generating material to produce an aerosol. The heater may comprise, for example, a flammable material, an electrically conductive material, or a susceptor.

[0179] A susceptor is a material that can be heated by penetration through a fluctuating magnetic field, such as an alternating magnetic field. The susceptor may be a conductive material, and consequently, penetration through the conductive material by the fluctuating magnetic field causes inductive heating of the heating material. The heating material may be a magnetic material, and consequently, penetration through the magnetic material by the fluctuating magnetic field causes magnetic hysteresis heating of the heating material. The susceptor may be both conductive and magnetic, and consequently, the susceptor can be heated by both heating mechanisms. A device configured to generate a fluctuating magnetic field is referred to herein as a magnetic field generator.

[0180] Aerosol modifiers are substances configured to modify an aerosol, for example, by altering the taste, flavor, acidity, or other properties of the aerosol. Aerosol modifiers may be provided within an aerosol modifier-releasing component that is capable of selectively releasing the aerosol modifier.

[0181] The aerosol modifier may be, for example, an additive or an adsorbent. The aerosol modifier may contain, for example, one or more of the following: flavorings, colorants, water, and carbon adsorbents. The aerosol modifier may be, for example, a solid, a liquid, or a gel. The aerosol modifier may be in the form of a powder, thread, or granules. The aerosol modifier does not necessarily contain a filter material.

[0182] An aerosol generator is a device configured to generate an aerosol from an aerosol-generating material. In some embodiments, the aerosol generator is a heater configured to supply thermal energy to the aerosol-generating material so as to release one or more volatile substances from the aerosol-generating material to form an aerosol. In some embodiments, the aerosol generator is configured to generate an aerosol from an aerosol-generating material without heating. For example, the aerosol generator may be configured to supply one or more of the aerosol-generating material to vibration, pressure increase, or electrostatic energy.

[0183] Articles, such as rod-shaped articles, are often named according to their length as follows: "Regular" (typically ranging from 68 to 75 mm, e.g., about 68 mm to 72 mm), "Short" or "Mini" (68 mm or less), "King Size" (typically ranging from 75 to 91 mm, e.g., about 79 mm to 88 mm), "Long" or "Super King" (typically ranging from 91 to 105 mm, e.g., about 94 mm to 101 mm), and "Ultra Long" (typically ranging from about 110 mm to 121 mm).

[0184] They are also named according to the circumference of the product: "Regular" (approximately 23-25mm), "Wide" (over 25mm), "Slim" (approximately 22-23mm), "Demi-Slim" (approximately 19-22mm), "Super Slim" (approximately 16-19mm), and "Micro Slim" (less than approximately 16mm).

[0185] Therefore, a king-size super-slim article would, for example, have a length of approximately 83 mm and a circumference of approximately 17 mm.

[0186] Each type can be manufactured using mouthpieces of different lengths. The mouthpiece length is approximately 30mm to 50mm. The tip paper is connected to the aerosol-generating material so that the tip paper covers the mouthpiece and overlaps the aerosol-generating material in the form of a rod of base material, for example, connecting the mouthpiece to the rod.

[0191] Figure 5 shows an example of a non-combustible aerosol supply device 100 for generating aerosols from an aerosol-generating medium / material such as an aerosol-generating material 3, one of the articles 1, 1', 1'', 1'''', 1'''' described herein. Schematically, device 100 can be used to heat a replaceable article 110 containing an aerosol-generating medium, such as articles 1, 1', 1'', 1'''', 1'''' described herein, to generate an aerosol or other inhalable medium to be inhaled by a user of device 100. Together, device 100 and the replaceable article 110 form a system.

[0192] Device 100 comprises a housing 102 (in the form of an outer cover) that surrounds and accommodates various components of device 100. Device 100 has an opening 104 in one end, through which an article 110 can be inserted for heating by a heating assembly. When in use, the article 110 may be fully or partially inserted into the heating assembly, where it may be heated by one or more components of the heater assembly.

[0193] When article 110 is inserted into device 100, the minimum distance between one or more components of the heater assembly and the tubular body 4a of article 110 may be in the range of 3 mm to 10 mm, for example, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.

[0194] The device 100 in this example includes a first end member 106, the first end member 106 having a lid 108 that is movable relative to the first end member 106 to close the opening 104 when the article 110 is not in place. In Figure 5, the lid 108 is shown in an open configuration, but the lid 108 can be moved to a closed configuration. For example, the user may slide the lid 108 in the direction of arrow "B".

[0195] Device 100 may also include a user-operable control element 112, such as a button or switch, which operates device 100 when pressed. For example, a user may turn on device 100 by operating the switch 112.

[0196] Device 100 may also include electrical components such as a socket / port 114 that can receive a cable for charging the device 100's battery. For example, the socket 114 could be a charging port, such as a USB charging port.

[0197] Figure 6 depicts the device 100 of Figure 5 with the outer cover 102 removed and the item 110 absent. The device 100 defines a longitudinal axis 134.

[0198] As shown in Figure 6, the first end member 106 is located at one end of the device 100, and the second end member 116 is located at the opposite end of the device 100. The first and second end members 106, 116 together define at least partially the end faces of the device 100. For example, the bottom surface of the second end member 116 defines at least partially the bottom surface of the device 100. The edge of the outer cover 102 may also define a portion of the end face. In this example, the lid 108 also defines a portion of the top surface of the device 100.

[0199] The end of the device closest to the opening 104 may be known as the proximal end (or mouth end) of the device 100, as it is closest to the user's mouth during use. During use, the user inserts an article 110 into the opening 104 and operates the user control unit 112 to begin heating the aerosol-generating material and aspirate the aerosol generated within the device. This causes the aerosol to flow through the device 100 along a channel toward the proximal end of the device 100.

[0200] The other end of the device furthest from the opening 104 may be known as the distal end of device 100, as it is the end furthest from the user's mouth during use. When the user inhales the aerosol generated within the device, the aerosol flows out from the distal end of device 100.

[0201] Device 100 further comprises a power supply 118. The power supply 118 may be a battery, such as a rechargeable or non-rechargeable battery. Examples of suitable batteries include, for example, lithium batteries (such as lithium-ion batteries), nickel batteries (such as nickel-cadmium batteries), and alkaline batteries. The battery is electrically coupled to the heating assembly to heat the aerosol-generating material by supplying power under the control of a controller (not shown) as needed. In this example, the battery is connected to a central support 120 that holds the battery 118 in place.

[0202] The device further comprises at least one electronic module 122. The electronic module 122 may, for example, include a printed circuit board (PCB). The PCB 122 may support at least one controller, such as a processor, and memory. The PCB 122 may also have one or more electrical tracks for electrically connecting various electronic components of the device 100 together. For example, battery terminals may be electrically connected to the PCB 122 so that power can be distributed throughout the device 100. The socket 114 may also be electrically coupled to the battery via the electrical track.

[0203] In exemplary device 100, the heating assembly is an induction heating assembly comprising various components for heating the aerosol-generating material of article 110 via an induction heating process. Induction heating is the process of heating a conductive object (such as a susceptor) by electromagnetic induction. The induction heating assembly may comprise an inductive element, for example, one or more inductor coils, and a device for passing a variable current, such as an alternating current, through the inductive element. The variable current in the inductive element generates a fluctuating magnetic field. The fluctuating magnetic field penetrates a susceptor suitably positioned with respect to the inductive element, generating eddy currents inside the susceptor. The susceptor has electrical resistance to eddy currents, and therefore the flow of eddy currents against this resistance heats the susceptor by Joule heating. If the susceptor contains a ferromagnetic material such as iron, nickel, or cobalt, heat may also be generated by magnetic hysteresis losses within the susceptor, i.e., by a change in the orientation of time dipoles in the magnetic material as a result of alignment with the fluctuating magnetic field. In induction heating, compared to, for example, conduction heating, heat is generated inside the susceptor, enabling rapid heating. Furthermore, it allows for greater flexibility in structure and application, as no physical contact is required between the induction heater and the susceptor.

[0204] The induction heating assembly of exemplary device 100 comprises a susceptor structure 132 (referred to herein as the “susceptor”), a first inductor coil 124, and a second inductor coil 126. The first and second inductor coils 124, 126 are fabricated from a conductive material. In this example, the first and second inductor coils 124, 126 are fabricated from Litz wire / cable, which is wound helically to provide helical inductor coils 124, 126. Litz wire consists of a plurality of individual wires that are individually insulated and twisted together to form a single wire. Litz wire is designed to reduce skin effect losses in a conductor. In exemplary device 100, the first and second inductor coils 124, 126 are fabricated from copper Litz wire having a rectangular cross-section. In other examples, Litz wire may have a cross-section of other shapes, such as circular.

[0205] The first inductor coil 124 is configured to generate a first fluctuating magnetic field for heating a first section of the susceptor 132, and the second inductor coil 126 is configured to generate a second fluctuating magnetic field for heating a second section of the susceptor 132. In this example, the first inductor coil 124 is adjacent to the second inductor coil 126 in a direction along the longitudinal axis 134 of the device 100 (i.e., the first and second inductor coils 124, 126 do not overlap). The susceptor configuration 132 may consist of a single susceptor or two or more separate susceptors. The ends 130 of the first and second inductor coils 124, 126 may be connected to the PCB 122.

[0206] It will be understood that the first and second inductor coils 124 and 126 may, in some examples, have at least one characteristic that is different from each other. For example, the first inductor coil 124 may have at least one characteristic that is different from the second inductor coil 126. More specifically, in one example, the first inductor coil 124 may have a different inductance value than the second inductor coil 126. In Figure 7, the first and second inductor coils 124 and 126 are of different lengths such that the first inductor coil 124 is wound over a smaller section of the susceptor 132 than the second inductor coil 126. Thus, the first inductor coil 124 may contain a different number of turns than the second inductor coil 126 (assuming that the spacing between individual turns is substantially the same). In yet another example, the first inductor coil 124 may be made from a different material than the second inductor coil 126. In some examples, the first and second inductor coils 124 and 126 may be substantially identical.

[0207] In this example, the first inductor coil 124 and the second inductor coil 126 are wound in opposite directions. This can be useful when the inductor coils are active at different times. For example, the first inductor coil 124 may initially operate to heat a first section / part of article 110, and later the second inductor coil 126 may operate to heat a second section / part of article 110. Winding the coils in opposite directions helps reduce the current induced in the inactive coil when used with certain types of control circuits. In Figure 6, the first inductor coil 124 is a right-handed helical and the second inductor coil 126 is a left-handed helical. However, in another embodiment, the inductor coils 124, 126 may be wound in the same direction, or the first inductor coil 124 may be a left-handed helical and the second inductor coil 126 may be a right-handed helical.

[0208] In this example, the susceptor 132 is hollow and therefore defines a receptacle within which an aerosol-generating material is received. For example, article 110 can be inserted into the susceptor 132. In this example, the susceptor 120 is tubular with a circular cross-section.

[0209] The susceptor 132 may be made from one or more materials. Preferably, the susceptor 132 includes carbon steel having a nickel or cobalt coating.

[0210] In some examples, the susceptor 132 may include at least two materials that can be heated at two different frequencies for the selective aerosolization of at least two materials. For example, a first section of the susceptor 132 (heated by a first inductor coil 124) may include a first material, and a second section of the susceptor 132 (heated by a second inductor coil 126) may include a second different material. In another example, the first section may include first and second materials, and the first and second materials may be heated differently based on the operation of the first inductor coil 124. The first and second materials may be adjacent along an axis defined by the susceptor 132 and may form different layers within the susceptor 132. Similarly, the second section may include third and fourth materials, and the third and fourth materials may be heated differently based on the operation of the second inductor coil 126. The third and fourth materials may be adjacent along the axis defined by the susceptor 132, or they may form different layers within the susceptor 132. The third material may be, for example, the same as the first material, and the fourth material may be the same as the second material. Alternatively, each of the materials may be different. The susceptor may include, for example, carbon steel or aluminum.

[0211] The device 100 in Figure 6 further comprises an insulating member 128, which may generally be tubular and may at least partially surround the susceptor 132. The insulating member 128 may be constructed from any insulating material, such as plastic. In this particular example, the insulating member is constructed from polyetheretherketone (PEEK). The insulating member 128 helps to insulate the various components of the device 100 from the heat generated within the susceptor 132.

[0212] The insulating member 128 can also fully or partially support the first and second inductor coils 124, 126. For example, as shown in Figure 7, the first and second inductor coils 124, 126 are positioned around the insulating member 128 and are in contact with the radially outer surface of the insulating member 128. In some examples, the insulating member 128 does not abut the first and second inductor coils 124, 126. For example, there may be a small gap between the outer surface of the insulating member 128 and the inner surfaces of the first and second inductor coils 124, 126.

[0213] In a specific example, the susceptor 132, the insulating member 128, and the first and second inductor coils 124 and 126 are coaxial with respect to the central longitudinal axis of the susceptor 132.

[0214] Figure 7 shows a side view of the device 100 in partial cross-section. In this example, an outer cover 102 is present. The rectangular cross-sectional shapes of the first and second inductor coils 124 and 126 are more clearly visible.

[0215] The device 100 further comprises a support 136 that engages with one end of the susceptor 132 to hold the susceptor 132 in place. The support 136 is connected to the second end member 116.

[0216] The device may also include a second printed circuit board 138 associated within the control element 112.

[0217] Device 100 further comprises a second lid / cap 140 and a spring 142 positioned toward the distal end of device 100. The spring 142 allows the second lid 140 to be opened to provide access to the susceptor 132. The user can open the second lid 140 to clean the susceptor 132 and / or support 136.

[0218] The device 100 further comprises an expansion chamber 144 extending toward the opening 104 of the device away from the proximal end of the susceptor 132. At least partially within the expansion chamber 144 are a retaining clip 146 for contacting and holding the article 110 when the article 110 is received within the device 100. The expansion chamber 144 is connected to the end member 106.

[0219] Figure 8 is an exploded view of the device 100 from Figure 7, with the outer cover 102 omitted.

[0220] Figure 9A depicts a cross-section of a portion of the device 100 in Figure 8. Figure 9B depicts a magnified view of a region of Figure 9A. Figures 10A and 10B show an article 110 received within the susceptor 132, the article 110 being sized such that its outer surface abuts against the inner surface of the susceptor 132. This ensures that heating is performed most efficiently. The article 110 in this example comprises an aerosol-generating material 110a, which is positioned within the susceptor 132. The article 110 may also comprise other components such as a filter, packaging material, and / or a cooling structure.

[0221] Figure 9B shows that the outer surface of the susceptor 132 is separated from the inner surfaces of the inductor coils 124 and 126 by a distance 150 measured perpendicular to the longitudinal axis 158 of the susceptor 132. In one particular example, the distance 150 is approximately 3mm–4mm, approximately 3–3.5mm, or approximately 3.25mm.

[0222] Figure 9B further shows that the outer surface of the insulating member 128 is spaced from the inner surfaces of the inductor coils 124 and 126 by a distance 152 measured perpendicular to the longitudinal axis 158 of the susceptor 132. In one particular example, the distance 152 is approximately 0.05 mm. In another example, the distance 152 is substantially 0 mm, so that the inductor coils 124 and 126 are in contact with the insulating member 128.

[0223] In one example, the susceptor 132 has a wall thickness 154 of approximately 0.025 mm to 1 mm, or approximately 0.05 mm.

[0224] In one example, the susceptor 132 has a length of approximately 40mm-60mm, approximately 40mm-45mm, or approximately 44.5mm.

[0225] In one example, the insulating member 128 has a wall thickness 156 of approximately 0.25 mm to 2 mm, 0.25 mm to 1 mm, or approximately 0.5 mm.
