Embodiments for Carrying Out the Invention

[0014] According to the present disclosure, a “non-combustible” aerosol supply system is a system in which an aerosol-generating material (or its components), which is a constituent of the aerosol supply system, is not burned in order to facilitate the delivery of at least one substance to a user.

[0015] In some embodiments, the delivery system is a non-combustible aerosol supply system such as a power supply non-combustible aerosol supply system.

[0016] In some embodiments, the non-combustible aerosol supply system is an electronic cigarette also known as a vaping device or an electronic nicotine delivery system (ENDS), but the presence of nicotine in the aerosol-generating material is not a requirement.

[0017] In some embodiments, the non-combustible aerosol supply system is an aerosol-generating material heating system also known as a non-combustion heating system. An example of such a system is a tobacco heating system.

[0018] In some embodiments, the non-combustible aerosol supply system is a hybrid system that generates an aerosol by a combination of aerosol generating materials (one or more of which may be configured to be heated). Each aerosol generating material may be in the form of, for example, a solid, liquid, or gel, and may or may not contain nicotine. In some embodiments, the hybrid system includes a liquid or gel aerosol generating material and a solid aerosol generating material. The solid aerosol generating material may include, for example, tobacco or non-tobacco products.

[0019] Typically, the non-combustible aerosol supply system may comprise a non-combustible aerosol supply device and a consumable for use with the non-combustible aerosol supply device.

[0020] In some embodiments, the present disclosure relates to a consumable that includes an aerosol generating material and is configured for use with a non-combustible aerosol supply device. Throughout the present disclosure, these consumables may sometimes be referred to as articles.

[0021] The consumable is an article that includes or consists of an aerosol generating material and is intended to be partially or fully consumed during use by a user. The consumable may include 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, a wrapper, a mouthpiece, and / or an aerosol modifier. The consumable may also include an aerosol generator such as a heater that releases heat during use to generate an aerosol from the aerosol generating material. The heater may include, for example, a combustible material, a material that can be heated by electrical conduction, or a susceptor.

[0022] In some embodiments, the non-flammable aerosol supply system (including the non-flammable aerosol supply device) may include a power source and a controller. The power source may be, for example, an electrical power source or a heat-generating power source. In some embodiments, the heat-generating power source includes a carbon substrate capable of supplying energy in the form of heat to an aerosol-generating material or heat-transferring material adjacent to the heat-generating power source.

[0023] In some embodiments, the non-flammable aerosol supply system may include a consumable receiving area, an aerosol generator, an aerosol generating area, a housing, a mouthpiece, a filter, and / or an aerosol modifier.

[0024] In some embodiments, consumables used with a non-flammable aerosol supply device may include aerosol generating material, an aerosol generating material storage area, an aerosol generating material transfer component, an aerosol generator, an aerosol generating area, a housing, a wrapper, a filter, a mouthpiece, and / or an aerosol modifier.

[0025] The heating material (or susceptor) is a material that can be heated by the intrusion of a fluctuating magnetic field, such as an alternating magnetic field. The susceptor may be a conductive material so that induction heating of the heating material occurs upon intrusion of the fluctuating magnetic field. The heating material may be a magnetic material so that magnetic hysteresis heating of the heating material occurs upon intrusion of the fluctuating magnetic field. The susceptor may have both conductive and magnetic properties so that it can be heated by both heating mechanisms. In this specification, a device configured to generate a fluctuating magnetic field is referred to as a magnetic field generator.

[0026] Induction heating is the process by which a conductive object is heated by the penetration of a fluctuating magnetic field. This process is described by Faraday's law of induction and Ohm's law. An induction heater may comprise an electromagnet and a device that allows a fluctuating current, such as an alternating current, to pass through the electromagnet. When the electromagnet and the object to be heated are preferably positioned relative to each other so that the resulting fluctuating magnetic field generated by the electromagnet penetrates the object, one or more eddy currents are generated inside the object. The object has resistance to the flow of current. Therefore, when such eddy currents are generated in an object, the object is heated by the flow against its electrical resistance. This process is called Joule heating, Ohmian heating, or resistance heating. An object that can be inductively heated is known as a susceptor.

[0027] In one embodiment, the susceptor is in the form of a closed circuit. It has been found that when the susceptor is in the form of a closed circuit, the magnetic coupling between the susceptor and the electromagnet during use is enhanced, resulting in increased or improved Joule heating.

[0028] Magnetic hysteresis heating is a process in which an object made of a magnetic material is heated by the penetration of a fluctuating magnetic field. Magnetic materials are thought to contain many atomic-scale magnets, or magnetic dipoles. When a magnetic field penetrates such a material, the magnetic dipoles become aligned with the magnetic field. Therefore, when a fluctuating magnetic field, such as an alternating magnetic field generated by an electromagnet, penetrates a magnetic material, the orientation of the magnetic dipoles changes in response to the application of the fluctuating magnetic field. This reorientation of magnetic dipoles generates heat within the magnetic material.

[0029] If an object is both conductive and magnetic, both Joule heating and magnetic hysteresis heating can occur within the object due to the penetration of a fluctuating magnetic field. Furthermore, the use of magnetic materials can increase the magnetic field strength, which can amplify Joule heating.

[0030] In some embodiments, the heating material may be a metal such as aluminum, gold, or silver in the form of foil, for example. In some embodiments, the heating material may be a ferromagnetic material. Examples of ferromagnetic materials include metals such as iron, nickel, and cobalt, as well as alloys such as certain types of stainless steel (e.g., 430 grade stainless steel). In some embodiments, the heating material may be ferromagnetic stainless steel in the form of foil, for example.

[0031] In some cases, the thermal conductivity of the heating material may be in the range of 1 W / (m·K) to 500 W / (m·K). For example, the thermal conductivity of the heating material may be in the range of 10 W / (m·K) to 60 W / (m·K), 100 W / (m·K) to 250 W / (m·K), 150 W / (m·K) to 250 W / (m·K), or 200 W / (m·K) to 250 W / (m·K). In some cases, the specific heat capacity of the heating material may be in the range of 100 J / (kg·K) to 1000 J / (kg·K). For example, the specific heat capacity of the heating material may be in the range of 450 J / (kg·K) to 550 J / (kg·K), 800 J / (kg·K) to 1000 J / (kg·K), or 900 J / (kg·K) to 1000 J / (kg·K).

[0032] In each of the above processes, heat is generated within the object itself rather than from an external heat source. Therefore, by selecting suitable object materials and shapes, as well as suitable magnitudes and orientations of the fluctuating magnetic field, rapid heating and a more uniform heat distribution can be achieved within the object. Furthermore, since induction heating and magnetic hysteresis heating do not require a physical connection between the fluctuating magnetic field source and the object, the design flexibility and control of the heating profile are increased, and costs may be reduced.

[0033] As used herein, the terms "upstream" and "downstream" are relative terms defined with respect to the direction of the mainstream aerosol drawn through the article or device during use.

[0034] In the drawings described herein, the same reference numerals are used to indicate the same features, articles, or components.

[0035] Figure 1 is a side cross-sectional view of the aerosol product. The aerosol product is used in conjunction with a non-flammable aerosol supply device.

[0036] The aerosol product 1 comprises a continuous aerosol-generating material rod 10 and a coil 20 arranged around the aerosol-generating material rod 10. The aerosol-generating material may be any of the aerosol-generating materials described herein. In this example, the aerosol-generating material is tobacco material.

[0037] The coil 20 includes a heating material. In this example, the coil 20 is made of aluminum as a whole. In other examples, the coil may be made of at least one material selected from gold, iron, nickel, cobalt, copper, conductive carbon, and graphite. In some examples, the coil may be made of an alloy (e.g., bronze, ordinary carbon steel, stainless steel, or ferritic stainless steel).

[0038] During use, the heating material of the coil 20 is heated by a fluctuating magnetic field generated by the non-flammable aerosol supply device. The heat generated in the coil 20 is transferred to the aerosol generating material 10 through the wrapper 30, heating the aerosol generating material 10.

[0039] Furthermore, the aerosol product 1 includes a wrapper 30 surrounding the aerosol generating material rod 10. The wrapper 30 defines a cavity in which the aerosol generating material is disposed. The coil 20 is disposed around the wrapper 30.

[0040] In this example, the wrapper 30 includes paper. The wrapper 30 has an air permeability of less than 500 cholesta units (CU). In some examples, the wrapper may have an air permeability of less than 400 CU, 300 CU, 200 CU, or 100 CU. By using a wrapper with an air permeability of less than 500 cholesta units, the wrapper becomes less flammable, minimizing the risk of the wrapper igniting, for example, if a consumer attempts to set item 1 on fire with a flame. In this example, the wrapper 30 has an air permeability of about 0 CU. In other examples, the wrapper may have an air permeability of 30 CU, 40 CU, 60 CU, 70 CU, or 80 CU. As an addition or alternative to paper with an air permeability of less than 500 CU, the wrapper 30 may include a combustion suppression additive. The combustion suppression additive can prevent or limit the combustion of the wrapper 30, for example, when exposed to a flame.

[0041] In some examples, the wrapper may consist solely of paper. In other examples, the wrapper may consist of a metal layer, or may include a metal layer in addition to paper. For example, the wrapper may have a layer of aluminum foil. Such a metal layer can aid in uniform heat transfer throughout the aerosol-generating material of the article. This can help prevent any particular region of the aerosol-generating material from reaching its combustion temperature.

[0042] In this example, the aerosol product 1 comprises a mouthpiece 40 connected to an aerosol generating material rod 10. In some examples, the mouthpiece may be omitted.

[0043] In this example, the aerosol-generating material rod 10 is substantially cylindrical and has a substantially circular cross-section. In other examples, the aerosol-generating material rod may have other cross-sections, such as an oval or elliptical cross-section. In some examples, the aerosol-generating material rod may have a rectangular, square, triangular, or star-shaped cross-section. In some examples, the aerosol-generating material rod may have an irregular cross-section. In some examples, the cross-sectional shape of the coil may be selected to correspond to the cross-sectional shape of the aerosol-generating material rod.

[0044] In this example, the aerosol-generating material rod 10 is elongated and has a longitudinal axis (not shown). In this example, the coil 20 has a longitudinal axis (not shown) aligned with the longitudinal axis of the rod 10. In other words, the aerosol-generating material rod 10 and the coil 20 share a common longitudinal axis. This common longitudinal axis may be referred to as the longitudinal axis of article 1.

[0045] In this example, the coil 20 extends from the upstream longitudinal end 10a of the aerosol-generating material rod 10 in a direction parallel to the longitudinal axis of article 1, but does not extend to the downstream longitudinal end 10b of the aerosol-generating material rod 10. In other words, the coil 20 extends only partially along the aerosol-generating material rod 10. In this example, the coil 20 extends along approximately 70% of the length of the aerosol-generating material rod 10. In other examples, the coil may extend along 20%, 30%, 40%, 50%, 60%, 80%, or 90% of the length of the aerosol-generating material rod.

[0046] In this example, the coil 20 has a circular helical shape; that is, the coil 20 has a substantially constant radius along its length. In this example, the coil 20 has a substantially constant pitch along its length; that is, the width of the gap between any two adjacent turns of the coil 20, measured parallel to the longitudinal axis of the coil 20, is substantially the same as the width of the gap between any other two adjacent turns of the coil 20. In other examples, the pitch of the coil may vary along its length.

[0047] The length of aerosol product 1 may be approximately 80 mm to approximately 150 mm. In this example, the aerosol product has a length of approximately 120 mm.

[0048] The width (or diameter) of aerosol product 1 may be approximately 4 mm to approximately 10 mm. In this example, the aerosol product has a width or diameter of approximately 7.3 mm.

[0049] Figure 2 is a side cross-sectional view of the aerosol product. Aerosol product 1' shown in Figure 2 is intended for use with a non-flammable aerosol supply device and is similar to aerosol product 1 shown in Figure 1.

[0050] The aerosol product 1' comprises an elongated member 21 disposed within the aerosol generating material rod 10, and a connecting member 22 that connects the upstream end of the coil 20 to the upstream end of the elongated member 21.

[0051] The elongated member 21 includes a heat transfer material such as metal. This can assist in heat transfer throughout the aerosol-generating material rod 10 during use. In some examples, the elongated member 21 includes a heat transfer material that can be heated by the intrusion of a fluctuating magnetic field. As a result, heat may be generated in both the coil 20 and the elongated member 21 during use.

[0052] In this example, the elongated member 21 is made of aluminum as a whole. In other examples, the elongated member may be made of at least one material selected from gold, iron, nickel, cobalt, copper, conductive carbon, and graphite. In some examples, the elongated member may be made of an alloy (e.g., bronze, ordinary carbon steel, stainless steel, or ferritic stainless steel). The elongated member may include a resistance wire or ribbon, such as Kanthal® wire or ribbon.

[0053] In this example, the elongated member 21 has a longitudinal axis aligned with the longitudinal axis of article 1'. In other words, the elongated member 21 extends along the longitudinal axis of article 1'. In some examples, the elongated member may extend parallel to the longitudinal axis of the article.

[0054] In this example, the elongated member 21 is substantially cylindrical. In this example, the elongated member 21 has a diameter of 2.5 mm. In some examples, the elongated member 21 may have a diameter in the range of 1.5 mm to 3 mm. In other examples, the elongated member may be substantially planar.

[0055] In this example, the elongated member 21 is surrounded by the aerosol-generating material 10. In other words, the aerosol-generating material 10 extends around the elongated member 21.

[0056] In this example, the elongated member 21 is impermeable to air or volatile materials, and there are substantially no discontinuities. Therefore, the elongated member 21 can be manufactured relatively easily. However, in some examples, the elongated member may be permeable to air and / or volatile materials generated when the aerosol-generating material 10 is heated. This may help to capture volatile materials generated when the aerosol-generating material 10 is heated by the air passing through article 1'.

[0057] The connecting member 22 includes a heat transfer material that can be heated by the intrusion of a fluctuating magnetic field. In this example, the connecting member 22 is made entirely of aluminum. When in use, the connecting member 22 acts to transfer the heat generated in the coil 20 directly to the elongated member 21. This assists in efficient heat transfer throughout the aerosol-generating material 10.

[0058] In this example, the coil 20, the elongated member 21, and the conductive member 22 are integrally formed. In other words, the coil 20, the elongated member 21, and the connecting member 22 are formed as a single component.

[0059] In some examples, article 1' may include a catalyst material in at least a portion of the elongated member 21. The catalyst material may be provided on the entire elongated member 21 or on only (one or more) portions of the elongated member 21. The catalyst material may be in the form of a coating on the elongated member 21. Providing such a catalyst material on the elongated member 21 means that article 1' may have a heated chemically active surface when in use. The catalyst material may include one or more materials selected from the group consisting of aluminosilicate materials, iron, vanadium, platinum, or nickel.

[0060] When used, the catalyst material may exhibit the effect of converting potentially irritating substances into less irritating substances, or increasing the conversion rate. When used, the catalyst material may exhibit the effect of converting formic acid to methanol, for example, or increasing the conversion rate. In other embodiments, the catalyst material may exhibit the effect of converting other chemical substances, such as the conversion of acetylene to ethane by hydrogenation or the conversion of ammonia to nitrogen and hydrogen, or increasing the conversion rate. As an addition or alternative, the catalyst material may exhibit the effect of reacting carbon monoxide and water vapor to produce carbon dioxide and hydrogen (water-gas shift reaction, i.e., WGSR), or increasing the reaction rate.

[0061] Figure 3 is a schematic plan view of the components used to construct the aerosol product.

[0062] The components shown in Figure 3 include a sheet 10 containing an aerosol-generating material and a mesh 20 containing a heating material.

[0063] The aerosol-generating material may be any of the aerosol-generating materials described herein. In this example, the aerosol-generating material is tobacco material. In the example shown in Figure 3, a single continuous sheet of aerosol-generating material 10 is provided. In other examples, multiple discrete sheets or strips of aerosol-generating material may be used.

[0064] In this example, the mesh 20 is made of aluminum as a whole. In other examples, the mesh may be made of at least one material selected from gold, iron, nickel, cobalt, copper, conductive carbon, and graphite. In some examples, the mesh may be made of an alloy (e.g., bronze, ordinary carbon steel, stainless steel, or ferritic stainless steel).

[0065] In this specification, the term "mesh" refers to a structure in which openings or holes are regularly spaced apart between strands of a heated material. In the example shown in Figure 3, the openings are rhomboid, but this is not intended to be limiting. In other examples, the mesh may include openings of other shapes. For example, the mesh may include forward, rectangular, hexagonal, or circular openings.

[0066] In this example, the sheet 10 and mesh 20 are planar or substantially planar. However, the sheet 10 and mesh 20 can also be bent or wound to form a roll sheet, for example, as shown in Figure 4. A "roll sheet" means that the sheet 10 and mesh 20 are curved without being folded, and therefore have a helical shape in cross-section. Such a roll sheet is less susceptible to damage than a planar sheet, is convenient for storage and handling, and may be suitable for use with aerosol supply devices.

[0067] In this example, the mesh 20 is disposed on the first surface of the sheet 10 and is in contact with the aerosol-generating material of the sheet 10. More specifically, in this example, the entire or substantially entire first surface of the sheet 10 is covered by the mesh 20. However, in other examples, only a portion of the first surface of the sheet 10 may be covered by the mesh 20. Furthermore, in some examples, a second mesh (not shown) may be provided on the second surface of the sheet 10 opposite to the first surface. In some examples, the mesh containing the heating material may cover the entire first and second surfaces of the sheet 10, substantially the entire surface, or only a portion of the surface.

[0068] In some examples, the mesh of the heating material may be embedded in the sheet of the aerosol-generating material. In some examples, the mesh of the heating material may not be in direct contact with the sheet, but may still be in thermal communication with the sheet so that the heat generated by the heating material during use can heat the aerosol-generating material.

[0069] Figure 4 is a cross-sectional view of the aerosol product. The aerosol product is used in conjunction with a non-flammable aerosol supply device.

[0070] Article 2 in Figure 4 includes a roll sheet formed from the components described above with reference to Figure 3. In other words, the roll sheet includes a sheet 10 containing an aerosol-generating material and a mesh 20 containing a heating material. As shown in Figure 4, the roll sheet has a helical cross-section.

[0071] In this example, article 2 is elongated and cylindrical, with a substantially circular cross-section. Article 2 has a longitudinal axis (not shown). The axial length of the roll sheet of article 2 is greater than the diameter of the roll sheet (or the width perpendicular to the axial length).

[0072] During use, heat is generated in the heating material 20 of the roll sheet. Because the heating material 20 is in contact with the aerosol-generating material 10 of the roll sheet, heat easily transfers from the heating material 20 to the aerosol-generating material 10. In addition, the openings in the mesh 20 can act as an insulating layer to control the degree to which different areas of the aerosol-generating material 10 are heated. Areas of the aerosol-generating material that are in thermal contact with the mesh are less likely to be heated than areas of the aerosol-generating material that are in thermal contact with a continuous sheet of heating material. This can help to gradually generate aerosols by gradually heating the aerosol-generating material. The openings can be used to optimize the generation of complex eddy currents during use.

[0073] In this example, article 2 is provided with an adhesive (not shown) that is placed between the overlapping sections of the roll sheet and adheres these overlapping sections to each other. This helps to prevent the roll sheet from loosening. The adhesive may be an adhesive such as polyvinyl acetate (PVA) or ethylene vinyl acetate (EVA). In other examples, adhesives such as polysaccharide-based adhesives may be used. The adhesive may include, for example, guar gum, pectin, alginate, or a combination thereof. The alginate may include, for example, sodium alginate.

[0074] In this example, article 2 comprises an aerosol-generating material mass 11 that is separated from and surrounded by the roll sheet. During use, heat is generated in the heating material 20, and the roll sheet helps to retain this heat within article 2. This configuration also helps to heat the aerosol-generating material mass 11 with the heat generated during use. In this example, the entire aerosol-generating material mass 11 is arranged along the longitudinal axis of article 2. In other examples, a portion of the aerosol-generating material mass may be located at other positions within article 2. For example, at least a portion of the aerosol-generating material mass may be sandwiched between the overlapping portions of the roll sheet. In some examples, the aerosol-generating material mass may be omitted or may be annular. In such examples, article 2 may be annular.

[0075] In this example, article 2 comprises a wrapper 30 surrounding the roll sheet and a mouthpiece (not shown) connected to the roll sheet. In some examples, the mouthpiece may be omitted. The wrapper may be any of the wrappers described above with respect to the examples shown in Figures 1 and 2.

[0076] Figure 5a is a side cross-sectional view of the aerosol product. The aerosol product is used in conjunction with a non-flammable aerosol supply device.

[0077] Article 3 comprises a continuous aerosol-generating material rod 10. The rod 10 is elongated and has a longitudinal axis. The rod 10 is centered on the longitudinal axis of Article 3 and includes an axial region extending along the longitudinal axis.

[0078] In this example, article 3 comprises a single body 20 disposed in the axial region of the aerosol-generating material rod 10. The body 20 contains a heating material. In this example, the body 20 as a whole is made of 430 grade stainless steel. In other examples, the elongated member may be made of at least one material selected from aluminum, gold, iron, nickel, cobalt, copper, conductive carbon, and graphite. In some examples, the elongated member may be made of an alloy (e.g., bronze or ordinary carbon steel).

[0079] In some examples, article 3 may include a catalytic material in at least a portion of the body 20. The catalytic material may be provided on the entire body 20 or on only (one or more) portions of the body 20. The catalytic material may be in the form of a coating on the body 20. Providing such a catalytic material on the body 20 means that article 3 may have a heated chemically active surface when in use. The catalytic material may include one or more materials selected from the group consisting of aluminosilicate materials, iron, vanadium, platinum, or nickel.

[0080] The aerosol-generating material rod 10 has an upstream end 10a and a downstream end 10b, and a single body 20 is positioned in the axial region of the aerosol-generating material rod 10 such that its approximate center is located between the upstream and downstream ends 10a and 10b. However, in other examples, it may also be beneficial to position the body 20 at a location other than the center (for example, closer to the downstream end 10b than to the upstream end 10a). For example, the center of the body 20 can be positioned at approximately 25% to 45% of the distance from the downstream end 10b to the upstream end 10a. This may help to retain the body 20 on the aerosol-generating material rod 10 and reduce the possibility of it detaching from the upstream end 10a.

[0081] In some examples, there may be two or more bodies. Figure 5b shows an example of an aerosol product 3' comprising three bodies 20a, 20b, and 20c. In this example, the bodies 20a, 20b, and 20c are uniformly spaced apart along the longitudinal axis of the rod 10. In other words, the distance between any two adjacent bodies is the same as the distance between any other two adjacent bodies. Consecutive bodies are spaced at least about 2 mm, at least about 3 mm, or at least about 4 mm apart. In some examples, this spacing is about 3 mm, about 4 mm, or about 5 mm, or about 2 mm to about 10 mm (for example, about 3 mm to about 6 mm).

[0082] In the examples shown in Figures 5a and 5b, the body is substantially spherical and has a circular cross-section. The diameter of the body is approximately 2 mm. In other examples, the diameter of the body may be approximately 0.5 mm, 1 mm, 1.5 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, or 5 mm.

[0083] One or more bodies 20, 20a, 20b, 20c can be substantially spherical with a diameter of approximately 1 mm to 5 mm (e.g., approximately 2 mm to 4 mm, 3 mm, or 3.5 mm). In some examples, the diameter of one or more bodies 20, 20a, 20b, 20c is 30% to 70% (e.g., approximately 40% to 60%, or 50%) of the diameter of the aerosol product.

[0084] One or more bodies can be solid or hollow. For example, if the body is made of a conductive material, a hollow body is advantageous because it can provide a circular path for the current flowing through the material constituting the body. This can promote heat generation in the body. If the body is hollow, it can have a wall thickness of about 0.5 mm to about 3 mm (e.g., about 1 mm). As an addition or alternative, one or more bodies can be porous or breathable. For example, the material constituting one or more bodies can be open-cell foam or other porous materials. If a hollow body is provided, the walls of the body can be porous or breathable, and for example, have a pattern of openings in the walls. The walls can be formed, for example, as a spherically shaped mesh.

[0085] In some examples, the body may be substantially cylindrical and have a circular cross-section. In such examples, the diameter of the body may be approximately 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, or 5 mm.

[0086] In the examples shown in Figures 5a and 5b, articles 3 and 3' comprise a wrapper 30 surrounding the aerosol-generating material rod 10 and a mouthpiece 40 connected to the aerosol-generating material rod 10. In some examples, the mouthpiece may be omitted. The wrapper 30 may be any of the wrappers described above with respect to the examples shown in Figures 1 and 2.

[0087] Figure 6 shows a portion of the apparatus 4 that can be used in the manufacture of the articles shown in Figures 5a and 5b. During operation, tobacco material is drawn from a source, stretched in a set of stretching rollers (not shown), and compressed through a stuffer jet 53 and a tongue 54 of the garnish 55. In other examples, for example, in forms where the tobacco material may degrade with use of its components, the stretching rollers and / or stuffer jet may be omitted. As shown, the apparatus 4 has a rotatable transfer wheel 56. The rotatable transfer wheel 56 includes a plurality of recesses 56a and is configured so that the passing tobacco material and the body come into contact by delivering the heating material body directly from the circumferential recesses 56a to the tongue 54. The tobacco material is wrapped in a wrapper (e.g., a paper wrapper) in the garnish to form an elongated rod, which is then cut to form rod segments. Each rod segment contains a desired number of heating material bodies (e.g., one body, two bodies, three bodies, four bodies, or five bodies).

[0088] The transfer wheel 56 is oriented vertically and is rotatably mounted on a shaft to the main body 57 of the device 4. The wheel 56 has a disc portion 58 and a front portion 59 bolted to the disc portion 56. The disc portion 58 is positioned between the hopper 60 and the tongue portion 54 and is configured to sequentially move the heating material body between them.

[0089] The tongue portion 54 of the garnish 55 is tapered along its length to compress the tobacco material radially as it passes through the tongue portion 54. An opening is formed at the top of the tongue portion 54, and this opening is wide enough to receive the disc portion 58 of the transfer wheel 56 as it enters the tongue portion 54 through the opening, as shown in Figure 6.

[0090] As the wheel 56 rotates, the heating material body falls by gravity from the hopper 60 into a plurality of recesses 56a arranged circumferentially around the rim of the disc portion 58, as shown in Figure 6. The clockwise rotating wheel 56 transports the heating material body from the opening at the top of the tongue portion into the interior of the tongue portion. The heating material body exits the wheel 56 and enters the rod being formed. A housing 57a is provided around the rim of the disc portion 58 to prevent the heating material body from falling off the wheel 56.

[0091] Thus, the heating material body is delivered directly to the tongue portion of the garnish, but the path of the tobacco material is stably controlled and maintained until the rod is formed. Furthermore, since the heating material body is inserted during the compression of the tobacco material, the tobacco material is compressed around the heating material body, fixing them in place. Therefore, the position and spacing of the heating material bodies in the completed rod are determined solely by the position of the heating material bodies in the tobacco material passing through the tongue portion. This allows the device to precisely control the position of the heating material bodies with little variation between bodies or between rods. Preferably, the heating material bodies are positioned in the tobacco material so as to be located in the axial region of the completed rod.

[0092] The heating material body, after exiting the wheel 56, may fall by gravity from the recess 56a of the wheel 56 to the tobacco material passing through the tongue 54. Alternatively, the transfer wheel 56 may have a discharge mechanism (e.g., an air jet propulsion mechanism) configured to sequentially discharge the heating material body from the recess of the rim 58 to the tobacco material passing through the tongue 54. As an alternative or addition, the transfer wheel may be equipped with a suction pump configured to suck the heating material body in place in the recess before discharge.

[0093] Furthermore, this specification presents a method for producing aerosol products for use with a non-flammable aerosol supply device. This method, as shown in Figure 7, includes the steps of: moving an aerosol generating material along a transport path (S101); inserting one or more bodies into the axial region of the aerosol generating material (S102), wherein one or more bodies have a circular cross-section and a diameter in the range of 0.5 mm to 5 mm, and one or more bodies contain a heating material that can be heated by the intrusion of a fluctuating magnetic field (S103); and configuring the aerosol generating material as a continuous aerosol generating material rod (S103).

[0094] The step of inserting the body into the axial region of the aerosol-generating material may be performed such that the continuous bodies are spaced at least about 2 mm, at least about 3 mm, or at least about 4 mm apart. For example, the distance between the recesses 56a of the wheel 56 can determine the spacing of the bodies in the aerosol-generating material. In some examples, this spacing is about 3 mm, about 4 mm, or about 5 mm. The spacing between the bodies can provide a region of a continuous rod from which individual segments and / or groups of individual segments can be formed for use in manufacturing articles.

[0095] This method further includes the step of cutting a continuous aerosol-generating material rod to provide rod segments and configuring the rod segments as one or more articles. The step of configuring the rod segments as one or more articles may include configuring the rod segments as one or more aerosol-generating sections, each having an upstream end and a downstream end in the finished article, with the heating material body positioned closer to the downstream end than to the upstream end of the aerosol-generating section. In an alternative embodiment, the heating material body can be positioned approximately centered between the upstream and downstream ends.

[0096] Figures 8a, 8b, and 8c show an example of a method for producing an aerosol product, along with a material or body containing one or more filaments. The aerosol product is used in conjunction with a non-flammable aerosol supply device.

[0097] Referring to Figure 8a, one or more filaments 21 comprising a heating material (e.g., a heating material that can be inductively heated by exposure to a fluctuating magnetic field) are provided as described herein. The method includes the step of moving an aerosol-generating material 10 (in this case, tobacco material) along a transport path. The method further includes the step of supplying one or more filaments 21 to the aerosol-generating material 10 so that the filaments 21 are surrounded by the aerosol-generating material 10, as shown in Figure 8b. The filaments 21 may be supplied from a supply source such as a spool, via an outlet.

[0098] In this example, the filament 21 is made of aluminum as a whole. In other examples, the filament may contain or consist of at least one material selected from gold, iron, nickel, cobalt, copper, conductive carbon, and graphite. In some examples, the filament may contain or consist of an alloy (e.g., bronze, ordinary carbon steel, stainless steel, or ferritic stainless steel (430 grade stainless steel)). The filament may contain a resistance wire or ribbon, such as Kanthal® wire or ribbon. The aerosol-generating material rod or body 10 may contain a filament formed as a single material strand or a filament formed from multiple strands. For example, multiple metal or other material fibers may be formed as a multi-strand wire or thread and used as individual filaments 21. Multiple filaments may be supplied to the aerosol-generating material so as to be dispersed within the aerosol-generating material rod or body 10. For example, the aerosol-generating material rod or main body 10 may contain 1 to 20 filaments (e.g., 2 to 10 filaments or 3 to 6 filaments).

[0099] The filament 21 may be supplied by using a mechanical or electromechanical delivery device, such as a supply roller or conveyor. The delivery speed of such a mechanical or electromechanical delivery device may be adjusted to measure the filament 21 to the aerosol-generating material 10 at an appropriate speed, based on the speed of the aerosol-generating material 10 passing through the outlet. The combination of the filament 21 and the aerosol-generating material 10 may pass through the tongue of the garnish and may be wrapped in a wrapper at that time.

[0100] By placing the filament 21 in the aerosol generating material 10, an elongated assembly including the filament 21 is formed within the aerosol generating material 10.

[0101] A continuous aerosol-generating material rod 10, also referred to as the aerosol-generating material body 10, is formed by cutting the elongated assembly at predetermined longitudinal positions along the elongated assembly. In the example shown in Figure 8c, the filament 21 extends to the opposite longitudinal end of the aerosol-generating material rod or body 10 (for example, extending along the entire length of the rod or body). The aerosol-generating material rod or body 10 can be used with a non-flammable aerosol supply device configured to heat a heating material by induction. Alternatively, the aerosol-generating material rod or body 10 can be formed as an article by connecting one or more additional components, such as a mouthpiece component, to the rod or body. This article can be used with a non-flammable aerosol supply device configured to heat a heating material by induction.

[0102] In other examples, the construction of the article may not require cutting of an elongated assembly. In some such examples, the filament 21 may be the filament 21 of the article being manufactured, and the aerosol-generating material 10 itself may constitute the aerosol-generating material rod 10 of the article being manufactured. In some such examples, one or more filaments may not extend to the opposite longitudinal end of the aerosol-generating material rod 10.

[0103] Figures 9a and 9b show an example of a method for producing an aerosol product. The aerosol product is used in conjunction with a non-flammable aerosol supply device.

[0104] This method includes the step of preparing a continuous aerosol-generating material rod 10 and an elongated member 21 containing a heating material, as shown in Figure 9a. In this example, the aerosol-generating material is tobacco material.

[0105] In this example, the elongated member 21 is substantially cylindrical and has a first longitudinal end face 21a, a second longitudinal end face 21b, and a side surface 21c. In this example, the diameter of the elongated member 21 is 2.5 mm. In some examples, the diameter of the elongated member 21 may be in the range of 1.5 mm to 3 mm. In other examples, the elongated member may be planar.

[0106] In this example, the elongated member 21 is made of aluminum as a whole. In other examples, the elongated member may be made of at least one material selected from gold, iron, nickel, cobalt, copper, conductive carbon, and graphite. In some examples, the elongated member may be made of an alloy (e.g., bronze, ordinary carbon steel, stainless steel, or ferritic stainless steel). The elongated member may include a resistance wire or ribbon, such as Kanthal® wire or ribbon.

[0107] This method further includes the step of inserting the elongated member 21 into the longitudinal end 10a of the aerosol-generating material rod 10. After insertion, as shown in Figure 9b, the elongated member 21 is surrounded by the aerosol-generating material 10, and the first longitudinal end face 21a of the elongated member 21 is exposed. In other words, the first longitudinal end face 21a of the elongated member 21 is not covered by another material such as the aerosol-generating material 10.

[0108] In this example, the elongated member 21 extends beyond the longitudinal end 10a of the aerosol-generating material 10. In other examples, the elongated member 21 may be coplanar with the longitudinal end of the aerosol-generating material.

[0109] In some examples, this method may further include the step of wrapping the aerosol-generating material rod 10 in a wrapper (not shown).

[0110] Figure 10 is a schematic side cross-sectional view of an example of the system. The system 1000 comprises an article 100 and a non-flammable aerosol supply device 200. In this example, article 100 is the article shown in Figure 1. In other examples, article 100 may be any one of the aerosol products described herein.

[0111] The non-flammable aerosol supply device 200 comprises a main body 210 and a heating zone 211 for receiving the article 100. The non-flammable aerosol supply device 200 also includes a magnetic field generator 212 configured to generate a fluctuating magnetic field that penetrates the heating material of the article 100 when the article 100 is placed in the heating zone 211.

[0112] The device 200 may include an air inlet (not shown) that fluidly connects the heating zone 211 to the outside of the device 200. Such an air inlet may be defined by the main body 210. The user may be able to inhale the aerosol generated by the aerosol-generating material of the article 100 by taking in the aerosol through the mouthpiece 102 of the article 100. Once the aerosol is removed from the article 100, air may be drawn into the heating zone 211 through the air inlet of the device 200.

[0113] In this example, the main body 210 includes a heating zone 211. In this example, the heating zone 211 includes a recess for receiving at least a portion of the article 100. In other examples, the heating zone 211 may be a shelf, a surface, or a projection, and may require mechanical engagement with the article for cooperation with or reception of the article. In this example, the heating zone 211 is elongated and sized and molded to accommodate a portion of the article 100. In other examples, the heating zone 211 may be sized to accommodate the entire article.

[0114] In this example, the magnetic field generator 212 includes a power source 213, a coil 214, a device 216 that passes a fluctuating current such as an alternating current through the coil 214, a controller 217, and a user interface 218 for user operation of the controller 217.

[0115] In this example, the power source 213 is a rechargeable battery. In other examples, the power source 213 may be another non-rechargeable battery, a capacitor, a battery-capacitor hybrid, or a connection to a commercial power source.

[0116] The coil 214 may be in any preferred form. In this example, the coil 214 is a helical coil made of a conductive material such as copper. In some examples, the magnetic field generator 212 may include a permeable core around which the coil 214 is wound. Such a permeable core concentrates the magnetic flux generated by the coil 214 during use to generate a stronger magnetic field. The permeable core may be made of, for example, iron. In some examples, the permeable core may extend only in part along the length of the coil 214 to concentrate the magnetic flux in a specific region. In some examples, the coil may be a flat coil; that is, the coil may be a two-dimensional helix. In this example, the coil 214 surrounds the heating zone 211. The coil 214 extends along a longitudinal axis that is substantially aligned with the longitudinal axis of the heating zone 211. The two aligned axes coincide. In other examples, the two aligned axes may be parallel to each other or oblique.

[0117] In this example, as shown in Figure 10, when article 100 is received in the recess 211, the longitudinal axis of the recess 211 substantially coincides with the longitudinal axis of article 100. In this example, the impedance of the coil 214 of the magnetic field generator 212 is equal to, or substantially equal to, the impedance of the coil 104 of article 100. Alternatively, if the impedance of the coil 104 of article 100 is lower than the impedance of the coil 214 of the magnetic field generator 212, the voltage generated in the coil 104 of article 100 during use will be lower than the voltage that could be generated in the coil 104 of article 100 if the impedances matched. Alternatively, if the impedance of the coil 104 of article 100 is higher than the impedance of the coil 214 of the magnetic field generator 212, the current generated in the coil 104 of article 100 during use will be smaller than the current that could be generated in the coil 104 of article 100 if the impedances matched. Matching impedances can help maximize the heating power generated in the coil 104 of article 100 during heating in use, through a balance of voltage and current. The system 1000 in this example comprises the article shown in Figure 1, but other examples may comprise the article shown in Figure 2. In such other examples, the impedance of the coil 214 of the magnetic field generator 212 may be equal to, or substantially equal to, the impedance of the coil of the article.

[0118] In this example, the device 216 that passes the fluctuating current through the coil 214 is electrically connected between the power source 213 and the coil 214. In this example, the controller 217 is electrically connected to the power source 213 and is also communicatively connected to the device 216 to control the device 216. More specifically, in this example, the controller 127 is configured to control the supply of power from the power source 213 to the coil 214 by controlling the device 216. In this example, the controller 217 comprises an integrated circuit (IC), such as an IC, on a printed circuit board (PCB). In other examples, the controller 217 may take a different form. In some examples, the non-flammable aerosol supply device may have only one electrical or electronic component comprising the device 216 and the controller 217.

[0119] In this example, the controller 217 is operated by user operation of the user interface 218. In this example, the user interface 218 is located outside the main unit 210. The user interface 218 may include push buttons, toggle switches, dials, touchscreens, etc. In other examples, a user interface located away from the non-flammable aerosol supply device may be provided. Such a user interface may be connected to the non-flammable aerosol supply device using wireless communication methods such as Bluetooth. For example, such a user interface may be implemented as part of a mobile electronic device such as a mobile phone that can communicate with the non-flammable aerosol supply device using wireless communication methods such as Bluetooth. Users may be able to remotely control the non-flammable aerosol supply device using the user interface of their respective mobile phones.

[0120] In this example, the user's operation of the user interface 218 causes the controller 217 to pass an alternating current through the coil 214 of the device 216. This causes the coil 214 to generate an alternating magnetic field. The coil 214 and the heating zone 211 of the non-flammable aerosol supply device 200 are suitably positioned relative to each other so that when the article 100 is placed in the heating zone 211, the fluctuating magnetic field generated by the coil 214 penetrates the heating material of the article 100. In this example, the fluctuating magnetic field generated by the coil 214 penetrates the heating material of the coil 104.

[0121] In some examples, the heating material of an article is a conductive material such as aluminum. In such examples, when a magnetic field penetrates the heating material, one or more eddy currents are generated within the heating material. The flow of eddy currents within the heating material, relative to its electrical resistance, causes the heating material to heat up by Joule heating. In some examples, the heating material is a magnetic material such as ferromagnetic stainless steel. In such examples, heat is generated within the heating material because the orientation of magnetic dipoles within the heating material changes with the applied fluctuating magnetic field.

[0122] The non-flammable aerosol supply device 200 includes a temperature sensor 219 configured to detect the temperature of the heating zone 211. The temperature sensor 219 is communicably connected to the controller 217 so that the controller 217 can monitor the temperature of the heating zone 211. Based on one or more signals received from the temperature sensor 219, the controller 217 may cause the device 216 to adjust, as necessary, the characteristics of the fluctuations or alternating current passing through the coil 214 so that the temperature of the heating zone 211 is kept within a predetermined temperature range. These characteristics may be, for example, amplitude, frequency, or duty cycle. When used within the predetermined temperature range, sufficient heating of the aerosol-generating material in the article placed in the heating zone 211 causes at least one component of the aerosol-generating material to volatilize without combustion of the aerosol-generating material. Thus, the controller 217 (and the device 200 as a whole) is configured to cause heating of aerosol generation to volatilize at least one component of the aerosol-generating material without combustion of the aerosol generation. In some embodiments, the temperature range is approximately 50°C to 300°C, such as approximately 50°C to 250°C, approximately 50°C to 150°C, approximately 50°C to 120°C, approximately 50°C to 100°C, approximately 50°C to 80°C, or approximately 60°C to 70°C. In some embodiments, the temperature range is approximately 170°C to 220°C. In other embodiments, the temperature range may be outside this range. In some embodiments, the upper limit of the temperature range can exceed 300°C. In some embodiments, the temperature sensor 219 may be omitted. In some embodiments, the heating material may have a Curie point temperature selected based on the highest temperature at which it is desirable to heat the heating material, thereby preventing or inhibiting further heating above that temperature by induction heating of the heating material.

[0123] Items (for example, rod-shaped items) are often named according to their length ("Regular" (usually in the range of 68-75mm (e.g., approximately 68mm-72mm)), "Short" or "Mini" (68mm or less), "King Size" (usually in the range of 75-91mm (e.g., approximately 79mm-88mm)), "Long" or "Super King" (usually in the range of 91-105mm (e.g., approximately 94mm-101mm)), and "Ultra Long" (usually in the range of approximately 110mm-121mm)).

[0124] Furthermore, these are named according to the product's circumference ("Regular" (approx. 23-25mm), "Wide" (over 25mm), "Slim" (approx. 22-23mm), "Demi-Slim" (approx. 19-22mm), "Super-Slim" (approx. 16-19mm), "Micro-Slim" (less than 16mm)).

[0125] Therefore, a king-size super-slim item would, for example, have a length of approximately 83 mm and a circumference of approximately 17 mm.

[0126] Each type may be produced with mouthpieces of different lengths. The length of the mouthpieces is approximately 30 mm to 50 mm. The tip paper connects the mouthpiece to the aerosol-generating material and is typically longer than the mouthpiece (e.g., 3 to 10 mm) so as to cover the mouthpiece and overlap the aerosol-generating material (e.g., in the form of a rod of substrate material) and connect the mouthpiece to the rod.

[0127] The articles described herein, as well as their respective aerosol-generating materials and mouthpieces, may be constructed in any of the above-described forms, but are not limited thereto.

[0128] In some embodiments, the delivered substance may be an aerosol-generating material or a material that is not subject to aerosolization. Either material may optionally contain one or more active components, one or more fragrances, one or more aerosol-forming materials, and / or one or more other functional materials.

[0129] 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 form an aerosol by applying thermal energy to the aerosol-generating material, thereby causing one or more volatile substances to be released from the aerosol-generating material. 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 apply one or more of the following to the aerosol-generating material: vibration, high pressure, or electrostatic energy.

[0130] Aerosol-generating material is a material capable of generating an aerosol when energy is supplied, for example, by heating, irradiation, or any other method. The aerosol-generating material may be in the form of a solid, liquid, or gel, and may or may not contain active substances and / or flavorings. In some embodiments, the aerosol-generating material may include an "amorphous solid," which may be alternatively referred to as a "monolithic solid" (i.e., non-fibrous). In some embodiments, the amorphous solid may be a dry gel. The amorphous solid is a solid material capable of holding some fluid, such as a liquid, internally. In some embodiments, the aerosol-generating material may include, for example, about 50 wt%, 60 wt%, or 70 wt% to about 90 wt%, 95 wt%, or 100 wt% of an amorphous solid.

[0131] The aerosol-generating material may include one or more active substances and / or fragrances, one or more aerosol-forming materials, and optionally one or more other functional materials.

[0132] The aerosol-forming material may contain one or more constituent substances capable of forming aerosols. In some embodiments, the aerosol-forming material may contain one or more of the following: glycerin, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, meso-erythritol, ethyl vanillate, ethyl laurate, diethyl sulfate, triethyl citrate, triacetin, diacetin mixture, benzyl benzoate, benzyl phenylacetate, tributyline, lauryl acetate, lauric acid, myristic acid, and propylene carbonate. The total amount of the supplied aerosol-forming material can range from 10% to 30% by weight (e.g., 12% to 22% by weight) of the aerosol-generating material such as tobacco material.

[0133] One or more other functional materials may include one or more of the following: pH adjusters, colorants, preservatives, binders, fillers, stabilizers, and / or antioxidants.

[0134] The material may be present on or within the support to form a substrate. The support may be, for example, paper, cardboard, paperboard, thick paper, recycled material, plastic material, ceramic material, composite material, glass, metal, or alloy, or may contain these materials. In some embodiments, the support includes a susceptor. In some embodiments, the susceptor is embedded in the material. In some alternative embodiments, the susceptor is on one or both sides of the material.

[0135] Aerosol modifiers are typically located downstream of the aerosol generation area and are configured to modify the generated aerosol by altering, for example, the flavor, taste, acidity, or other properties of the aerosol. The aerosol modifier may be provided in an aerosol modifier release component that is operable to selectively release the aerosol modifier.

[0136] 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, colorings, water, and carbon adsorbents. The aerosol modifier may be, for example, a solid, a liquid, or a gel. The aerosol modifier may be in powder, thread, or granular form. The aerosol modifier may not have a filter material.

[0137] In this specification, the term "tobacco material" refers to any material including tobacco or its derivatives or substitutes. The term "tobacco material" may include one or more of tobacco, tobacco derivatives, extended tobacco, remanufactured tobacco, or tobacco substitutes. Tobacco material includes one or more of ground tobacco, tobacco fibers, loose tobacco, extruded tobacco, tobacco stems, tobacco laminas, remanufactured tobacco, and / or tobacco extracts.

[0138] In some embodiments, the delivered substance includes an active substance.

[0139] The active substances used herein may be physiologically active materials (materials intended to realize or enhance physiological reactions). Active substances may be selected from, for example, nutritional supplements, psychotropic drugs, and psychoactive agents. Active substances may be naturally occurring or synthesized.
