[0085] In the accompanying drawings described herein, the same reference numerals are used to indicate equivalent features, articles, or parts.

[0086] Figure 1a and Figure 1b This is a side sectional view of article 1 used in an aerosol delivery system, which includes an aerosol delivery device 100 (see...). Figures 4 to 6 ).

[0087] Article 1 has an upstream or distal end “D” and a downstream or proximal end “P”. The proximal end P includes a mouthpiece 2, and the distal end D includes an atomizing portion connected to the mouthpiece 2. In this example, the atomizing portion includes an atomizing material source 3 in the form of a rod. The atomizing material 3 may include strands or strips of multiple atomizing materials 3. For example, the atomizing material 3 may include strands or strips of multiple atomizable materials and / or strands or strips of multiple amorphous solids.

[0088] In this example, the aerosol-generating material 3 comprises multiple strands and / or strips of aerosol-generating material and is surrounded by packaging 4. In this example, packaging 4 is a moisture-proof packaging.

[0089] Multiple strands or strips of aerosol-generating material 3 can be aligned within the aerosol-generating portion such that their longitudinal dimensions are parallel to and aligned with the longitudinal axis X-X' of the article 1. Alternatively, the strands or strips can be arranged generally such that their aligned longitudinal dimensions are transverse to the longitudinal axis of the article 1.

[0090] In this example, the aerosol-generating material rod 3 has a circumference of approximately 22.7 mm. In alternative embodiments, the aerosol-generating material rod 3 may have any suitable circumference, for example, between approximately 20 mm and approximately 26 mm.

[0091] Article 1 is configured for use in a non-flammable aerosol supply device 100 (see...) Figure 4 In this device, the atomizer, in the form of a heating element 103, such as a blade or pin, is inserted into the atomizing material 3 of the atomizing part, as will be described in more detail below.

[0092] See below for reference Figure 2 (a) to (c) and Figure 3 In other embodiments described in more detail in (a) to (c), the heating element 30 is incorporated into the atomizing material 3 of the article 1 and forms an integral part of the article 1. In such embodiments, the heating element 30 may be a sensor. If the heating element 30 is a sensor, the device 200 may include a magnetic field generator 203 that surrounds the atomizing material 3 to inductively heat the heating element 30, which in turn heats the atomizing material 3. Such a device 200, as... Figure 7 As shown in the image.

[0093] The mouthpiece 2 includes a cooling section 5, also referred to as a cooling element, which is positioned downstream of the aerosol-generating material source 3. In this example, the cooling section 5 is adjacent to the aerosol-generating material source 3. In this example, the mouthpiece 2 also includes a material body 6 located downstream of the cooling section 5 and a hollow tubular element 7 located downstream of the material body 6 at the mouthpiece end 2 of the work-in-process 1.

[0094] The cooling section 5 includes a hollow channel with an inner diameter between approximately 1 mm and approximately 4 mm, for example, between approximately 2 mm and approximately 4 mm. In this example, the hollow channel has an inner diameter of approximately 3 mm. The hollow channel extends along the entire length of the cooling section 5. In this example, the cooling section 5 includes a single hollow channel. In alternative embodiments, the cooling section may include multiple channels, such as 2, 3, or 4 channels. In this example, the single hollow channel is substantially cylindrical, but in alternative embodiments, other channel geometries / cross-sections may be used. The hollow channel provides space in which aerosols drawn into the cooling section 5 can expand and cool down. In all embodiments, the cooling section 5 is configured to limit the cross-sectional area of ​​the hollow channel to restrict the movement of tobacco into the cooling section 5 during use.

[0095] The impermeable packaging 4 can have low friction with the aerosol-generating material 3, which allows for easier longitudinal displacement of the strands and / or strips of the aerosol-generating material 3 into the cooling section 5 when the heating element 103 is inserted into the aerosol-generating material rod 3. By providing the cooling section 5 directly adjacent to the aerosol-generating material source 3 and including internal channels within this diameter range, the longitudinal displacement of the strands and / or strips of the aerosol-generating material 3 when the heating element 103 of the device 100 is inserted into the aerosol-generating material rod 3 is reduced. In use, reducing the displacement of the aerosol-generating material 3 can advantageously result in a more consistent packing density of the aerosol-generating material 3 along the length of the rod, which can lead to more consistent and improved aerosol generation.

[0096] In the example, the cooling section 5 has a wall thickness in the radial direction. For a given outer diameter of the cooling section, the wall thickness of the cooling section 5 defines the inner diameter of the chamber surrounded by the wall of the cooling section 5. The cooling section 5 may have a wall thickness of at least about 1.5 mm to about 2 mm. In this embodiment, the wall thickness of the cooling section 5 is about 2 mm. By providing a cooling section 5 with a wall thickness within this range, in use, the retention of the aerosol generating material source 3 in the aerosol generating section is improved by reducing the longitudinal displacement of the strands and / or strips of the aerosol generating material 3 when the aerosol generator is inserted into the article 1.

[0097] The cooling section 5 is formed from filamentous bundles. Other structures can be used, such as multi-layered paper wound in parallel and having butt joints, to form the cooling section 5; or spirally wound paper layers, cardboard tubes, tubes formed using paper-forming processes, molded or extruded plastic tubes, or the like. The cooling section 5 is manufactured to have sufficient rigidity to withstand the axial compressive forces and bending moments that may occur during manufacturing and during use of the article 1.

[0098] The wall material of the cooling section 5 may be relatively non-porous, such that at least 90% of the mist generated by the mist-generating material 3 passes longitudinally through one or more hollow channels rather than through the wall material 5 of the cooling section. For example, at least 92% or at least 95% of the mist generated by the mist-generating material 3 may pass longitudinally through one or more hollow channels.

[0099] In the example, the mouthpiece 2 includes a diameter greater than 110 mm. 3 The internal volume of the cavity is hollow. It has been found that providing a cavity of at least this volume can form improved aerosol. The mouthpiece 2 includes, for example, a cavity formed within the cooling section 5, which has a volume greater than 110 mm. 3 and greater than 130 mm 3 The internal volume allows for further aerosol refinement. In some examples, the internal cavity comprises approximately 130 mm. 3 With approximately 230 mm 3 The volume between, for example, approximately 134 mm 3 or 227 mm 3 .

[0100] The cooling section 5 may be configured to provide a temperature difference of at least 40 degrees Celsius between the heated volatile component entering the first upstream end of the cooling section 5 and the heated volatile component exiting the second downstream end of the cooling section 5. The cooling section 5 may also be configured to provide a temperature difference of at least 60 degrees Celsius, at least 80 degrees Celsius, or at least 100 degrees Celsius between the heated volatile component entering the first upstream end of the cooling section 5 and the heated volatile component exiting the second downstream end of the cooling section 5. This temperature difference across the length of the cooling section 8 protects the temperature-sensitive material body 6 from the high temperatures of the atomizing material 3 when it is heated.

[0101] When in use, the aerosol generating section may exhibit a pressure drop from about 15 to about 40 mm H2O. In some embodiments, the aerosol generating section exhibits a pressure drop across the aerosol generating section from about 15 to about 30 mm H2O.

[0102] In this embodiment, the moisture-impermeable packaging 4 surrounding the aerosol-generating material rod 3 comprises aluminum foil. In other embodiments, the packaging 4 comprises paper packaging, optionally including a barrier coating to make the material of the packaging 4 substantially moisture-impermeable. Aluminum foil has been found to be particularly effective in enhancing aerosol formation within the aerosol-generating material 3. In this example, the aluminum foil has a metal layer with a thickness of about 6 μm. In this example, the aluminum foil has a paper backing. However, in alternative arrangements, the aluminum foil can be of other thicknesses, for example, between 4 μm and 16 μm. The aluminum foil does not need to have a paper backing, but can have a backing formed of other materials, for example, to help provide appropriate tensile strength to the foil, or it can be without a backing material. Metal layers or foils other than aluminum can also be used. The total thickness of the packaging can be between 20 μm and 60 μm, or between 30 μm and 50 μm, which can provide packaging with appropriate structural integrity and thermal transfer properties. The tensile force that can be applied to the packaging before it breaks can be greater than 3,000 gf, for example, between 3,000 gf and 10,000 gf or between 3,000 gf and 4,500 gf. When the packaging includes paper or paper backing, i.e., a cellulose-based material, the packaging can have a basis weight greater than about 30 gsm. For example, packaging 4 can have a basis weight in the range of about 40 gsm to about 70 gsm, which can provide improved rigidity to the aerosol generating material rod 3. The improved rigidity provided by packaging 4 with a basis weight in this range can make the aerosol generating material rod 3 more resistant to wrinkling or other deformation under the forces exerted on the article during use, such as when the article is inserted into the device and / or the heat generator is inserted into the article 1.

[0103] In this example, the moisture-impermeable packaging material 4 is also substantially air-impermeable. In alternative embodiments, the packaging material 4 may have a permeability of less than 100 Coresta units or less than 60 Coresta units. It has been found that low-permeability packaging materials, such as those with a permeability of less than 100 Coresta units or less than 60 Coresta units, result in improved aerosol formation in the aerosol-generating material 3. It is not desirable to be bound by theory; it is assumed that this is due to reduced loss of aerosol compounds through the packaging material 10. The permeability of the packaging material 10 can be measured according to ISO 2965:2009, concerning the determination of air permeability for materials used as cigarette paper, filter rod forming paper, and filter connecting paper.

[0104] Material body 6 defines a generally cylindrical overall external shape and is enclosed within a first filter rod forming paper 8. The first filter rod forming paper 8 may have a basis weight of less than 50 gsm or between about 20 gsm and 40 gsm. The first filter rod forming paper 8 may have a thickness between 30 μm and 60 μm, or between 35 μm and 45 μm. The first filter rod forming paper 8 may be a non-porous filter rod forming paper, for example, having a permeability of less than 100 Coresta units, such as less than 50 Coresta units. However, in other embodiments, the first filter rod forming paper 8 may be a porous filter rod forming paper, for example, having a permeability greater than 200 Coresta units.

[0105] like Figure 1a and Figure 1b As shown, the mouthpiece 2 of article 1 includes an upstream end 2a adjacent to the aerosol-generating material rod 3. At the proximal end, the mouthpiece 2 has a hollow tubular element 7 formed of filamentous bundles. It has been advantageously found that this significantly reduces the temperature of the outer surface of the mouthpiece 2 at the downstream end 2b of the mouthpiece, where it contacts the consumer's mouth during use of article 1. Furthermore, it has been found that the use of the tubular element 7 significantly reduces the temperature of the outer surface of the mouthpiece 2, even upstream of the tubular element 7. Without being bound by theory, it is assumed that this is because the tubular element 7 guides the aerosol closer to the center of the mouthpiece 2, thus reducing heat transfer from the aerosol to the outer surface of the mouthpiece 2.

[0106] The “wall thickness” of the hollow tubular element 7 corresponds to the thickness of the wall of the tube 7 in the radial direction. This can be measured, for example, using calipers. Advantageously, the wall thickness is greater than 0.9 mm, or 1.0 mm or more. The wall thickness around the entire wall of the hollow tubular element 7 can be substantially constant. However, where the wall thickness is not substantially constant, the wall thickness at any point around the hollow tubular element 7 can be greater than 0.9 mm, or 1.0 mm or more. In this embodiment, the wall thickness of the hollow tubular element 4 is approximately 1.3 mm.

[0107] The tipping paper 9 is wrapped around the entire length of the mouthpiece 2 and a portion of the aerosol-generating material rod 3, and has an adhesive on its inner surface to connect the mouthpiece 2 and the rod 3. In this embodiment, the aerosol-generating material rod 3 is encased in packaging 4, which forms a first packaging material, and the tipping paper 9 forms an outer packaging material that extends at least partially over the aerosol-generating material rod 3 to connect the mouthpiece 2 and the rod 3. In some examples, the tipping paper 9 may extend only partially over the aerosol-generating material rod 3.

[0108] The article 1 has an airflow level of approximately 10% for the aerosol drawn through it. In an alternative embodiment, the article 1 may have an airflow level between 1% and 20% for the aerosol drawn through it, for example, between 1% and 12%. Airflow at these levels helps increase the consistency of the aerosol inhaled by the user at the mouthpiece 2b, while also aiding the aerosol cooling process. Airflow is provided directly to the mouthpiece 2 of the article 1. In this example, airflow is provided to the cooling section 5, which has been found to be particularly advantageous in aiding the aerosol generation process. Airflow is provided through perforations 10, which in this example are formed as a single row of laser-drilled perforations located 13 mm downstream of the mouthpiece 2b of the mouthpiece 2. In an alternative embodiment, two or more rows of airflow perforations 10 may be provided. These perforations 10 pass through the tipping paper 9, the second filter rod forming paper 11, and the cooling section 5. In an alternative embodiment, airflow may be provided to the mouthpiece 2 at other locations, such as to the material body 6 or the first tubular element 7. The article 1 can be configured such that the perforation 10 is located at a distance of approximately 28 mm or less from the upstream end of the article 1, or between 20 mm and 28 mm from the upstream end of the article 1. In this example, the perforation is located at approximately 25 mm from the upstream end of the article 1.

[0109] The aerosol-generating material 3 includes plant-based materials, such as tobacco materials. The aerosol-generating material 3 can be a sheet or fragment of an aerosolizable material that includes plant-based materials (such as tobacco materials).

[0110] Plant-based materials can be microparticles or granular materials. In some embodiments, the plant-based material is a powder. Alternatively or additionally, tobacco materials may include tobacco strips, filaments, or fibers. For example, tobacco materials may include tobacco particles, fine particles, fibers, strips, and / or filaments. In some embodiments, the tobacco material consists of particles or fine particles of tobacco material.

[0111] The density of tobacco materials affects the rate at which heat is conducted through the material. The lower the density, for example, below 900 mg / cc, the slower the heat is conducted through the material, thus allowing for a more continuous release of aerosol.

[0112] Tobacco materials may include reconstituted tobacco materials with a density of less than about 900 mg / cc, such as paper-based reconstituted tobacco materials. For example, aerosol-generating materials may include reconstituted tobacco materials with a density of less than about 800 mg / cc. Alternatively or additionally, aerosol-generating materials may include reconstituted tobacco materials having a density of at least 350 mg / cc.

[0113] Tobacco material may include tobacco obtained from any part of the tobacco plant. In some embodiments, tobacco material includes tobacco leaves.

[0114] Sheets or fragments may contain 5% to about 90% tobacco leaves by weight.

[0115] The aerosol generating material 3 may include an aerosol forming material. The aerosol forming material contains one or more components capable of forming an aerosol.

The aerosol forming material may be glycerol or propylene glycol.

[0116] The aerosolizable material sheets or fragments contain an aerosol-forming agent material. The aerosol-forming material is provided in an amount of up to about 50% by weight of the sheet or fragment on a dry weight basis. In some embodiments, the aerosol-forming material is provided in an amount of about 5% to about 40%, about 10% to about 30%, or about 10% to about 20% by weight of the sheet or fragment on a dry weight basis.

[0117] The aerosol-generating material 3 may include filler. In some embodiments, the sheet or fragment contains filler. The filler is typically a non-tobacco component, i.e., a component that does not contain ingredients derived from tobacco. The filler may contain one or more inorganic filler materials, such as calcium carbonate, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, magnesium carbonate, and suitable inorganic adsorbents, such as molecular sieves. The filler may be a non-tobacco fiber, such as wood fiber, pulp, or wheat fiber. The filler may be a material containing cellulose or a material containing cellulose derivatives. The filler component may also be a non-tobacco casting material or a non-tobacco extruded material.

[0118] The aerosol-generating material 3 described herein may contain an aerosol modifier, such as any flavoring described herein. In one embodiment, the aerosol-generating material 3 contains menthol. When the aerosol-generating material 3 is incorporated into an article 1 for use in an aerosol supply system, the article may be referred to as mentholized article 1. The aerosol-generating material 3 may contain 0.5 mg to 20 mg of menthol, 0.7 mg to 20 mg of menthol, between 1 mg and 18 mg of menthol, or between 8 mg and 16 mg of menthol.

[0119] In some embodiments, the composition comprises an "amorphous solid" that forms an aerosol, which may alternatively be referred to as a "monolithic solid" (i.e., non-fibrous). In some embodiments, the amorphous solid may comprise a dried gel. An amorphous solid is a solid material in which some fluid (e.g., liquid) can be retained.

[0120] In some examples, amorphous solids include:

[0121] - 1-60 wt% gelling agent;

[0122] - 0.1-50 wt% aerosol-forming materials; and

[0123] - 0.1-80 wt% flavorings;

[0124] These weights are calculated based on dry weight.

[0125] In some other embodiments, the amorphous solid comprises:

[0126] - 1-50 wt% gelling agent;

[0127] - 0.1-50 wt% aerosol-forming materials; and

[0128] - 30-60 wt% spices;

[0129] These weights are calculated based on dry weight.

[0130] Amorphous solid materials can be supplied in sheet or fragment form. Amorphous solid materials can take the same form as atomizable materials, either in sheet or fragment form.

[0131] The aerosol-generating material 3 may include paper-reconstituted tobacco material. The composition may alternatively or additionally contain any form of tobacco described herein. The aerosol-generating material 3 may include sheets or fragments containing tobacco material comprising between 10% and 90% by weight of tobacco leaves, wherein the aerosol-forming material is provided in an amount of up to about 20% by weight of the sheet or fragment, and the remainder of the tobacco material comprises paper-reconstituted tobacco.

[0132] When the aerosol generating material 3 includes an amorphous solid material, the amorphous solid material may be a dried gel including menthol.

[0133] exist Figure 4 The components of an embodiment of a non-flammable aerosol supply device 100 according to an embodiment of the present invention are shown in a simplified manner. Specifically, in... Figure 4 The components of the non-flammable aerosol supply device 100 are not shown to scale. This is for simplification. Figure 4 Elements that are not relevant to understanding this embodiment have been omitted.

[0134] like Figure 4 As shown, the non-flammable aerosol supply device 100 includes a non-flammable aerosol supply device having a housing 101, the housing 101 including a region 102102 for receiving the article 1.

[0135] Region 102 is arranged to receive article 1. When article 1 is received in region 102, at least a portion of the aerosol-forming material 3 is in thermal proximity to heater 103. When article 1 is fully received in region 102, at least a portion of the aerosol-forming material 3 may be in direct or indirect contact with heater 103. The aerosol-forming material 3 will release a series of volatile compounds at different temperatures. By controlling the maximum operating temperature of the electrically heated aerosol-generating system 100, the selective release of undesirable compounds can be controlled by preventing the release of selected volatile compounds.

[0136] like Figure 5 As shown, a power source 104, such as a rechargeable lithium-ion battery, is located within the housing 101. A controller 105 is connected to the heater 103, the power source 104, and a user interface 106, such as a button or display. The controller 105 controls the power supplied to the heater 103 to regulate its temperature. Typically, the aerosol-forming substrate is heated to a temperature between 250 and 450 degrees Celsius.

[0137] Figure 6 yes Figure 4 A schematic cross-section of a non-flammable aerosol supply device 100 of the type shown, wherein a heater 103 is inserted into the aerosol-generating material 3 of the article 1. The non-flammable aerosol supply device 100 is shown as being engaged with the aerosol-generating article 1 for consumption by a user.

[0138] The housing 101 of the non-flammable aerosol supply device 100 defines a cavity-like region 102, which opens at its proximal end (or mouth end) for receiving the aerosol-generating article 1 for consumption. A heating assembly including a heater 103 spans the distal end of the cavity. The heater 103 is held by a heater mount (not shown) such that the effective heating area of ​​the heater is located within the cavity. When the aerosol-generating article 1 is fully received within the cavity, the effective heating area of ​​the heater 103 is positioned within the aerosol-generating portion of the aerosol-generating article 1.

[0139] The heater 103 is configured to insert into the aerosol-generating material 3. When the article 1 is pushed into the device 100, the conical point of the heater 103 engages with the aerosol-generating material 3. By applying force to the article 1, the heater 103 penetrates into the aerosol-generating material 3. When the article 1 is properly engaged with the non-flammable aerosol supply device 100, the heater 103 is inserted into the aerosol-generating material 3. When the heater 103 is actuated, the aerosol-generating material 3 is heated and generates or releases volatile substances. When the user inhales the mouthpiece 2, air is drawn into the article 1 and the volatile substances condense to form an inhalable aerosol. This aerosol passes through the mouthpiece 2 of the article 1 and enters the user's mouth.

[0140] Figure 7Another embodiment of the non-flammable aerosol supply device 200 according to an embodiment of the present invention is shown below. Figure 7 Components of an embodiment of the non-flammable aerosol supply device 200 are also shown in a simplified manner.

[0141] like Figure 7 As shown, the non-flammable aerosol supply device 200 includes a non-flammable aerosol supply device having a housing 201, the housing 201 including a region 202 for receiving the article 1.

[0142] In this embodiment, the heating element 103 is omitted. Instead, the device 200 has a surrounding Figure 2 The varying magnetic field generator 203 in region 202 into which the article 1 of (a) to (c) is inserted, i.e., article 1 is incorporating a material layer or lining forming the heating element 30, as described in more detail below. The control of device 200 is similar to that described above regarding... Figure 5 The control described is different from the fact that heater 103 is replaced by a variable magnetic field generator 203.

[0143] Regardless of the composition of the aerosol-generating material 3, embodiments of the present invention provide an aerosol-generating material 3 having a cavity 20 that extends longitudinally from the distal end D toward the proximal end P, such that when the article 1 is inserted into the device 100 in a first embodiment, as Figures 4 to 6 As shown, the heating element 103 of the device 100 is housed in the cavity 20.

[0144] In some embodiments, the cavity 20 is coaxial with the longitudinal axis X-X' of the article, and the aerosol-generating material 3 may be tubular. In other embodiments, the cavity 20 may be offset from the longitudinal axis X-X', and / or include multiple cavities 20, one or more of which may accommodate the heating element 103 when the article 1 is inserted into the device 100.

[0145] The cavity can extend the entire length of the aerosol-generating material 3. Alternatively, the cavity 20 can extend a portion of the length of the aerosol-generating material 3.

[0146] Although cavity 20 can have a circular cross-section, such as Figure 2 The cross-sectional view shown in (a) is shown, but other cross-sections are also possible. For example, the cross-section of cavity 20 can be in the shape of a narrow aperture, such as... Figure 2 As shown in (b), or it could be star-shaped, such as Figure 2 As shown in (c). It can also have some other non-circular cross-section. In these embodiments, the heating element 103 can be cylindrical, i.e., in the form of a pin, to avoid having to orient the heating element 103 and the cavity 20 relative to each other before insertion. However, the heating element 103 and the cavity 20 can both have the same cross-sectional shape.

[0147] Regardless of the shape of the cavity 20, and regardless of whether the cavity 20 and the heater 103 have the same cross-sectional shape, the heater 103 can fit tightly or interfere with the cavity 20. In some embodiments, the size of the heater 103 can be slightly larger than the size of the cavity 20, such that the aerosol generating material 3 is compressed or deformed by the heater 103 during insertion into the device 100.

[0148] In any embodiment of the invention, the inner wall 21a of the cavity 20 of the aerosol generating material 3 may be coated, lined, or otherwise defined by a material layer 30 different from the aerosol generating material. Figure 3 (a) to (c)). For example, an amorphous solid and / or gel and / or sheet layer such as paper, or another layer different from the aerosol-generating material of the first layer, may be disposed on, against, or near the inner wall 21a within the cavity 20. The cavity in the aerosol-generating material 3 thus extends through the second material layer 30. Compared to the aerosol-generating material, the inner material layer 30 may have a lower coefficient of friction, making it easier for the heating element 103 to slide into the cavity 20.

[0149] In some embodiments of the invention, the heater 103 and the cavity 20 into which it is inserted have different cross-sections, such that the heating element 103 does not completely fill the cavity 20, thereby leaving one or more channels for aerosol flow between the inner wall 21 of the aerosol generating material 3 and the heating element 103. By controlling the size of the channels in relation to the size of the heating element 103, the resistance to suction through the aerosol generating material 3 can be controlled and optimized for a specific product or market.

[0150] In some embodiments, the channel for aerosol flow is formed as an integral part of the cavity 20 in which the heating element 103 is housed. Specifically, the heating element 103 and the cavity 20 have different cross-sectional shapes to form a channel between the heating element 103 and the inner wall of the aerosol generating material 3.

[0151] In any embodiment of the invention, the cavity 20 in the aerosol generating material 3 may be non-uniform along its length. For example, the shape of the cavity 20 may vary along the length of the aerosol generating material 3, or the cavity 20 may gradually narrow. For example, the cavity 20 may narrow in a direction extending away from the distal end of the aerosol generating material 3.

[0152] The cavity 20 of the aerosol-generating material 3 that has been lined or coated has been referenced above. Figure 1b A specific embodiment comprising a lined cavity 20 is shown. In this embodiment, the cavity 20 is lined with a heating element 30, which forms an integral part of the article 1. According to Figure 1b Product 1 can still be compared with the reference. Figures 4 to 6 The described apparatus is used together, wherein the heating element 103 is housed in the cavity 20, such that heat is transferred or conducted from the heater 103 to the aerosol-generating material 3 via the heating element 30, which may be in contact with one or both of the aerosol-generating material 3 and the heater 103. However, Figure 2 Articles 1 of (a) to (c) may also be referenced Figure 7 The device 200 described is used together with a variable magnetic field generator 203 for inductive heating of a heating element 30 in the lining of a cavity 20 in aerosol generating material 3.

[0153] like Figure 3 As shown in (a) to (c), and regardless of the type of device 100, 200 used with article 1, the lined cavity 20 in the aerosol generating material 3 may have a circular cross-section, such as... Figure 2 As shown in (a), or it can be a narrow aperture, such as Figure 2 As shown in (b), or it could be star-shaped, such as Figure 3 As shown in (c). Alternatively, it can have any other regular or irregular shape. In each of these embodiments, the material layer 30 lining the cavity 20 is shaped to correspond to the shape of the cavity 20.

[0154] The heating element 30 lining the cavity 20 is made of a conductive and potentially magnetic material. It can be made of an iron-containing material. Ideally, it is made of a material that can be inductively heated in response to a changing magnetic field generated in its vicinity.

[0155] The heating element 30 can be permeable. For example, it can be perforated, formed of a mesh, or have openings therein to allow air and mist to pass through the heating element 30. In other embodiments, it can be formed of an impermeable sheet of material. The heating element 30 can be formed of a single component or multiple components. For example, it can be formed of multiple discrete portions separated from each other along the longitudinal direction.

[0156] In any embodiment of the invention, the aerosol-generating material 3 can be extruded through a die. In this manufacturing method, the die may be provided with a mandrel on which the aerosol-generating material 3 is extruded to form a cavity 20 in the aerosol-generating material 3. The mandrel may be cylindrical, but it may have other shapes or configurations to form cavities with the desired cross-sectional shape within the aerosol-generating material 3.

[0157] If the cavity 20 is lined with a material layer 30, the material layer 30 can be formed as a tube, and the material layer 30 can be stretched or otherwise supplied to the mandrel when the aerosol generating material 3 is extruded on the mandrel.

[0158] In another embodiment, the manufacture of the article 1, which includes a material layer 30 lining the cavity 20, may include forming Figure 8 The steps of the aerosol generation section shown in (a) to (e). In step (a), the material sheet 30a forming the material layer 30 is lowered onto the mold 40 and pressed into the mold 40, as shown in (a) to (e). Figure 8 As indicated by the arrow in (a). The mold 40 defines the tubular shape required for the aerosol generating section and has a cylindrical inner surface with a coaxial, upright model 40a in the shape of a cavity 20. The sheet 30a is pressed into the mold 40 so that it conforms to the shape of the mold, as shown in Figure 40. Figure 8 As shown in (b). Next, as Figure 8 As shown in (c), the atomizing material 3 is filled into a lined mold. The atomizing material 3 can be pressed or stamped into the mold before demolding the article 1. Figure 8 As shown in (d), the aerosol generating portion includes a molding material layer 30 containing aerosol generating material 3, wherein the molding material layer serves as a liner for the cavity and wraps around one end of the article 1 and extends on its outer surface.

[0159] To complete the aerosol generation section, the end of the article 1 covered with material layer 30 is cut off (along...). Figure 8 The line CC in (d) causes the material layer 30 lining the cavity 20 to separate from the material sheet 30a, thereby forming an outer layer or enclosure surrounding the aerosol-generating material 3 to form Figure 8 (e) shows the aerosol generation section.

[0160] In a further variation, mold 40 may not have an upright form, and the method may include filling the mold with atomizing material 3 once the mold has been lined with material layer 30. The mold is then rotated to generate sufficient centrifugal force to cause the atomizing material 3 to abut against material layer 30a around the outside of the mold, thereby forming a central cavity 20 in the atomizing material 3.
