Embodiments for Carrying Out the Invention

[0014] According to the present disclosure, a “non-flammable” 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-flammable aerosol supply system such as a power supply type non-flammable aerosol supply system.

[0016] In some embodiments, the non-flammable 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-flammable aerosol supply system is an aerosol generating material heating system also known as a non-combustion heating type 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 to be used 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 consumed in part or in whole during use by a user. The consumable may comprise one or more other components such as an aerosol generating material storage area, an aerosol generating material transfer component, an aerosol generating area, a housing, a wrapper, a mouthpiece, and / or an aerosol modifier. Further, the consumable may comprise 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 heatable by electrical conduction, or a susceptor.

[0022] In some embodiments, a nonflammable aerosol supply system (such as its nonflammable aerosol supply device, etc.) may include a power source and a controller. The power source may be, for example, a power supply or a heat generating power source. In some embodiments, the heat generating power source includes a carbon substrate capable of supplying power in the form of heat to an aerosol generating material or a heat transfer material proximate to the heat generating power source.

[0023] In some embodiments, the nonflammable aerosol supply system may include an area for receiving consumables, an aerosol generator, an aerosol generation area, a housing, a mouthpiece, a filter, and / or an aerosol modifier.

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

[0025] A 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 such that inductive heating of the heating material occurs due to the intrusion of the fluctuating magnetic field. The heating material may be a magnetic material such that magnetic hysteresis heating of the heating material occurs due to the intrusion of the fluctuating magnetic field. The susceptor may have both characteristics so as to be heatable by both the conductive and magnetic 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 a process in which a conductive object is heated by the penetration of a variable magnetic field. This process is described by Faraday's law of induction and Ohm's law. An induction heater may include an electromagnet and a device for passing a variable current, such as an alternating current, through the electromagnet. When the electromagnet and the object to be heated are preferably arranged relative to each other such that the variable magnetic field generated by the electromagnet penetrates the object, one or more eddy currents are generated inside the object. The object has a resistance to the flow of current. Therefore, when such eddy currents are generated in the object, the object is heated by the flow against the electrical resistance of the object. This process is referred to as Joule heating, Ohmic heating, or resistive heating. An object that can be induction-heated is known as a susceptor.

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

[0028] Magnetic hysteresis heating is a process in which an object made of a magnetic material is heated by the penetration of a variable magnetic field. A magnetic material is considered to contain many atomic-scale magnets, i.e., magnetic dipoles. When a magnetic field penetrates such a material, the magnetic dipoles align with the magnetic field. Therefore, when a variable magnetic field, such as an alternating magnetic field generated by an electromagnet, penetrates the magnetic material, the orientation of the magnetic dipoles changes with the application of the variable magnetic field. Heat is generated in the magnetic material due to such reorientation of the magnetic dipoles.

[0029] When the object is conductive and magnetic, both Joule heating and magnetic hysteresis heating can occur in the object due to the penetration of the variable magnetic field into the object. Furthermore, since the use of a magnetic material strengthens the magnetic field, Joule heating can be increased.

[0030] In some embodiments, the heating material may be a metal such as aluminum, gold, or silver in the form of, for example, foil. In some embodiments, the heating material may be a ferromagnetic material. Examples of ferromagnetic materials include metals such as iron, nickel, and cobalt, and 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, for example, foil.

[0031] In some examples, 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 examples, 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 inside the object itself rather than by heat transfer from an external heat source. Therefore, particularly, by selecting a suitable object material and shape, as well as a suitable magnitude of the alternating magnetic field and its orientation with respect to the object, rapid temperature rise and more uniform heat distribution in the object can be achieved. Furthermore, in induction heating and magnetic hysteresis heating, since a physical connection between the alternating magnetic field source and the object is not required, the design freedom and control of the heating profile increase, and the cost may be reduced.

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

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

[0035] Figure 1 is a side sectional view of an aerosol generating article. The aerosol generating article is used together with a non-combustible aerosol supply device.

[0036] The aerosol generating article 1 includes a continuous aerosol generating material rod 10 and a coil 20 disposed around the aerosol generating material rod 10. The aerosol generating material may be any of the aerosol generating materials described in this specification. In this example, the aerosol generating material is a 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 (for example, bronze, plain carbon steel, stainless steel, or ferritic stainless steel).

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

[0039] In addition, the aerosol generating article 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 Coresta 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 Coresta units, the wrapper becomes less flammable, minimizing the risk of the wrapper igniting, for example, when a consumer tries to light an article 1 with a flame. In this example, the wrapper 30 has an air permeability of approximately 0 CU. In other examples, the wrapper may have an air permeability of 30 CU, 40 CU, 60 CU, 70 CU, or 80 CU. In addition to or as an alternative to paper with an air permeability of less than 500 CU, the wrapper 30 can include a combustion suppressant additive. The combustion suppressant 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 of only 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 comprise a layer of aluminum foil. Such a metal layer can assist 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 - generating article 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) that is 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 the 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 the 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 spiral 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, parallel to the longitudinal axis of the coil 20, the width of the gap measured between any two adjacent windings of the coil 20 is substantially the same as the width of the gap between any other two adjacent windings of the coil 20. In other examples, the pitch of the coil may vary along its length.

[0047] The length of the aerosol generating article 1 may be from about 80 mm to about 150 mm. In this example, the aerosol generating article has a length of about 120 mm.

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

[0049] Figure 2 is a side cross-sectional view of the aerosol generating article. The aerosol generating article 1' shown in Figure 2 is for use with a non-combustible aerosol supply device and is similar to the aerosol generating article 1 shown in Figure 1.

[0050] The aerosol generating article 1' includes an elongate member 21 disposed within the aerosol generating material rod 10 and a connecting member 22 connecting the upstream end of the coil 20 to the upstream end of the elongate member 21.

[0051] The elongate 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 elongate member 21 includes a heat transfer material that can be heated by the intrusion of a varying magnetic field. Thereby, during use, heat can be generated in both the coil 20 and the elongate member 21.

[0052] In this example, the elongated member 21 is entirely made of aluminum. 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 (for example, bronze, plain carbon steel, stainless steel, or ferritic stainless steel). The elongated member may include a resistance wire or ribbon such as, for example, Kanthal (registered trademark) wire or ribbon.

[0053] In this example, the elongated member 21 has a longitudinal axis aligned with the longitudinal axis of the article 1'. In other words, the elongated member 21 extends along the longitudinal axis of the 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 has substantially no discontinuities. For this reason, the manufacture of the elongated member 21 can be relatively easy. However, in some examples, the elongated member may be permeable to air and / or volatile materials generated during heating of the aerosol - generating material 10. This can help the air passing through the article 1' to take in the volatile materials generated during heating of the aerosol - generating material 10.

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

[0059] In some examples, the article 1' may include a catalyst material on at least a portion of the elongated member 21. The catalyst material may be provided throughout the elongated member 21 or only on 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 the article 1' can have a heated chemically active surface during use. The catalyst material may include one or more materials selected from the group consisting of aluminosilicate materials, iron, vanadium, platinum, or nickel.

[0060] During use, the catalyst material may act to convert potential irritants into less irritating substances or to increase the conversion rate. During use, the catalyst material may act to convert, for example, formic acid into methanol or to increase the conversion rate. In other embodiments, the catalyst material may act to convert other chemical substances, such as the conversion of acetylene to ethane by hydrogenation or the conversion of ammonia to nitrogen and hydrogen, or to increase the conversion rate. As an addition or alternative to this, the catalyst material may show an action of reacting carbon monoxide and steam to produce carbon dioxide and hydrogen (the water-gas shift reaction or WGSR), or to increase the reaction rate.

[0061] Figure 3 is a schematic plan view of the components used in the configuration of the aerosol-generating article.

[0062] The components shown in FIG. 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 a tobacco material. In the example shown in FIG. 3, a single continuous sheet of the aerosol - generating material 10 is provided. In other examples, a plurality of discrete sheets or strips of the 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, plain carbon steel, stainless steel, or ferritic stainless steel).

[0065] As used herein, the term "mesh" refers to a structure in which openings or holes are regularly spaced between strands to which a heating material is connected. In the example shown in FIG. 3, the openings are diamond - shaped, but this is not intended to be limiting in any way. In other examples, the mesh may include openings of other shapes. For example, the mesh may include square, rectangular, hexagonal, or circular openings.

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

[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 the entire first surface of the sheet 10 is covered by the mesh 20. However, in other examples, only a part of the first surface of the sheet 10 may be covered by the mesh 20. Further, in some examples, a second mesh (not shown) may be provided on the second surface opposite to the first surface of the sheet 10. In some examples, the entire, substantially the entire, or only a part of each of the first and second surfaces of the sheet 10 may be covered by a mesh including a heating material.

[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 such 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 an aerosol - generating article. The aerosol - generating article is used with a non - flammable aerosol supply device.

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

[0071] In this example, the article 2 is slender and cylindrical, having a substantially circular cross - section. The article 2 has a longitudinal axis (not shown). The axial length of the roll sheet of the 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. Since the heating material 20 is in contact with the aerosol-forming material 10 of the roll sheet, heat easily transfers from the heating material 20 to the aerosol-forming material 10. Also, the openings of the mesh 20 can act as a heat-insulating layer that controls the degree to which different regions of the aerosol-forming material 10 are heated. The area of the aerosol-forming material in thermal contact with the mesh is less likely to be heated than a configuration where the area of the aerosol-forming material is in thermal contact with a continuous sheet of the heating material. This can help to gradually generate aerosol by gradually heating the aerosol-forming material. The openings can be used to optimize the generation of complex eddy currents during use.

[0073] In this example, the article 2 is disposed between the overlapping portions of the roll sheet and includes an adhesive (not shown) that adheres these overlapping portions 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] Also, in this example, the article 2 includes a mass 11 of aerosol-forming material that is discrete from the roll sheet 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 the article 2. Also, this configuration also helps to enable the mass 11 of aerosol-forming material to be heated by the heat generated during use. In this example, the entire mass 11 of aerosol-forming material is arranged along the longitudinal axis of the article 2. In other examples, a portion of the mass of aerosol-forming material may be arranged at other positions within the article 2. For example, at least a portion of the mass of aerosol-forming material may be sandwiched between the overlapping portions of the roll sheet. In some examples, the mass of aerosol-forming material may be omitted or may be annular. In such examples, the article 2 may be annular.

[0075] Also, in this example, the article 2 includes 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 FIGS. 1 and 2.

[0076] FIG. 5a is a side cross-sectional view of an aerosol-generating article. The aerosol-generating article is used with a non-flammable aerosol supply device.

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

[0078] In this example, the article 3 includes a single body 20 disposed in the axial region of the aerosol-generating material rod 10. The body 20 includes a heating material. In this example, the body 20 is made of 430-grade stainless steel as a whole. 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 (for example, bronze or plain carbon steel).

[0079] In some examples, the article 3 may include a catalyst material in at least a part of the body 20. The catalyst material may be provided throughout the body 20 or only in one or more parts of the body 20. The catalyst material may be in the form of a coating on the body 20. Providing such a catalyst material on the body 20 means that the article 3 can have a heated chemically active surface during use. The catalyst 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 disposed in the axial region of the aerosol-generating material rod 10 such that its approximate center is disposed between the upstream and downstream ends 10a, 10b. However, in other examples, it may also be beneficial to dispose the body 20 at a position other than the center (for example, closer to the downstream end 10b than the upstream end 10a). For example, the center of the body 20 can be disposed at about 25% to about 45% of the distance from the downstream end 10b to the upstream end 10a. This can help reduce the possibility that the body 20 is held by the aerosol-generating material rod 10 and falls off from the upstream end 10a.

[0081] In some examples, two or more bodies may be provided. FIG. 5b shows an example of an aerosol-generating article 3' comprising three bodies 20a, 20b, 20c. In this example, the bodies 20a, 20b, 20c are uniformly spaced 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. The consecutive bodies are spaced apart by at least about 2 mm, at least about 3 mm, or at least about 4 mm. 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 FIGS. 5a and 5b, the body is substantially spherical and has a circular cross-section. The diameter of the body is about 2 mm. In other examples, the diameter of the body may be about 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 of the bodies 20, 20a, 20b, 20c can be substantially spherical with a diameter of about 1 mm to about 5 mm (for example, about 2 mm to about 4 mm, about 3 mm, or about 3.5 mm). In some examples, the diameter of one or more of the bodies 20, 20a, 20b, 20c is 30% to 70% (for example, about 40% to 60%, or about 50%) of the diameter of the aerosol-generating article.

[0084] One or more bodies can be solid or hollow. For example, when the body is formed 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. When the body is hollow, it can have a wall thickness of about 0.5 mm to about 3 mm (for example, 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 a closed-cell foam material or other porous materials. When provided as a hollow body, the wall of the body can be porous or breathable, for example, having a pattern of openings in the wall. The wall can be formed, for example, as a mesh formed in a spherical shape.

[0085] In some examples, the body can be substantially cylindrical and have a circular cross-section. In such examples, the diameter of the body can be about 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 FIGS. 5a and 5b, the articles 3, 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 can be any of the wrappers described above with respect to the examples shown in FIGS. 1 and 2.

[0087] Figure 6 shows a part of an apparatus 4 that can be used in the manufacture of the articles shown in FIGS. 5a and 5b. In operation, tobacco material is drawn from a supply source, stretched in a set of stretching rollers (not shown), and compressed through a staff jet 53 and the tongue 54 of the garniture 55. In other examples, for forms where the tobacco material may be degraded by the use of components, the stretching rollers and / or the staff 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 such that the heating material body contacts the passing tobacco material by delivering the heating material body directly from the circumferential recesses 56a to the tongue 54. After the tobacco material is wrapped in a wrapper (e.g., a paper wrapper) in the garniture to form an elongated rod, rod segments are formed by cutting. Each rod segment includes a desired number of heating material bodies (e.g., 1 body, 2 bodies, 3 bodies, 4 bodies, or 5 bodies).

[0088] The transfer wheel 56 is oriented vertically and is rotatably attached to the body 57 of the apparatus 4 on a shaft. The wheel 56 has a disk portion 58 and a front portion 59 bolted to the disk portion 56. The disk portion 58 is disposed between the hopper 60 and the tongue 54 and is configured to sequentially move the heating material body therebetween.

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

[0090] When the wheel 56 rotates, as shown in FIG. 6, the heating material body falls by gravity from the hopper 60 into a plurality of recesses 56a arranged circumferentially around the rim of the disk portion 58. The wheel 56 rotating clockwise conveys 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 disk portion 58 to prevent the heating material body from falling off the wheel 56.

[0091] In this way, the heating material body is directly delivered to the tongue portion of the garniture, but the path of the tobacco material is stably controlled and maintained in that state until the rod is formed. Further, since the heating material body is inserted during the compression of the tobacco material, the tobacco material is compressed around the heating material body and fixes them in place. Therefore, the position and spacing of the heating material bodies in the finished rod are determined only by the position where the heating material bodies are arranged in the tobacco material passing through the tongue portion. Thereby, this apparatus enables accurate control of the position of the heating material body with little variation between bodies or between rods. The heating material body is preferably arranged in the tobacco material so as to be disposed in the axial region of the finished rod.

[0092] The heating material body exiting the wheel 56 can fall by gravity from the recess 56a of the wheel 56 into the tobacco material passing through the tongue portion 54. Alternatively, the transfer wheel 56 may have a discharge mechanism (for example, an air jet propulsion mechanism) configured to sequentially discharge the heating material body from the recess of the rim portion 58 into the tobacco material passing through the tongue portion 54. As an alternative or addition to this, the transfer wheel is provided with a suction pump configured to suck the heating material body before discharge and hold it in place in the recess.

[0093] Also, this specification presents a method for manufacturing an aerosol generating article for use with a non-combustible aerosol supply device. As shown in FIG. 7, the method includes a step (S101) of moving an aerosol generating material along a travel path, and a step (S102) of inserting one or more bodies into an axial region of the aerosol generating material, wherein the one or more bodies have a circular cross-section and a diameter in the range of 0.5 mm to 5 mm, and the one or more bodies include a heating material that can be heated by the intrusion of a variable magnetic field, step (S102), and a step (S103) of configuring the aerosol generating material as a continuous aerosol generating material rod.

[0094] The step of inserting the bodies into the axial region of the aerosol generating material may be performed such that successive bodies are spaced apart by at least about 2 mm, at least about 3 mm, or at least about 4 mm. 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 that can be configured into individual segments and / or groups of individual segments for use in manufacturing the article by cutting.

[0095] The method further includes a step of cutting the 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 portions each having an upstream end and a downstream end in the finished article, with the heating material body disposed closer to the downstream end than the upstream end of the aerosol generating portion. In an alternative embodiment, the heating material body can be disposed substantially centered between the upstream and downstream ends.

[0096] FIGS. 8a, 8b, and 8c show an example of a method for manufacturing an aerosol generating article and a material or body including one or more filaments. The aerosol generating article is for use with a non-combustible aerosol supply device.

[0097] Referring to FIG. 8a, as described herein, one or more filaments 21 are provided that include a heating material (e.g., a heating material that can be inductively heated by exposure to a varying magnetic field). The method includes moving an aerosol-forming material 10 (in this case, a tobacco material) along a travel path. The method further includes, as shown in FIG. 8b, supplying one or more filaments 21 to the aerosol-forming material 10 such that the filaments 21 are surrounded by the aerosol-forming material 10. The filaments 21 may be adapted to be supplied from a source such as a spool through an outlet.

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

[0099] The supply of the filament 21 may be realized by using a mechanical or electromechanical delivery device such as a supply roller or a conveyor, for example. Such a mechanical or electromechanical delivery device may be configured such that its delivery speed is adjusted to meter the filament 21 to the aerosol-forming material 10 at an appropriate speed, for example, based on the speed of the aerosol-forming material 10 passing through the outlet. The combination of the filament 21 and the aerosol-forming material 10 may pass through the tongue of the garniture and may also be wrapped with a wrapper at that time.

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

[0101] The continuous aerosol-forming material rod 10, also referred to as the aerosol-forming material body 10, is formed by cutting the elongated assembly at a predetermined longitudinal position along the elongated assembly. In the example shown in FIG. 8c, the filament 21 extends to the opposite longitudinal end of the aerosol-forming material rod or body 10 (for example, extends over the entire length of the rod or body). The aerosol-forming material rod or body 10 can be used together with a non-combustible aerosol supply device configured to heat a heating material by induction. Alternatively, the aerosol-forming 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 together with a non-combustible aerosol supply device configured to heat a heating material by induction.

[0102] In other examples, it may not be necessary to cut the elongated assembly in the construction of the article. In some such examples, the filament 21 may be the filament 21 of the article being manufactured, or the aerosol-forming material 10 itself may constitute the aerosol-forming 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-forming material rod 10.

[0103] Figures 9a and 9b show an example of a method of manufacturing an aerosol-generating article. The aerosol-generating article is used with a non-combustible aerosol supply device.

[0104] As shown in FIG. 9a, the method includes the step of providing an elongated member 21 including a continuous aerosol-forming material rod 10 and a heating material. In this example, the aerosol-forming material is a 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 face 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 entirely of aluminum. 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, plain carbon steel, stainless steel, or ferritic stainless steel). The elongated member may include a resistive wire or ribbon such as, for example, Kanthal® wire or ribbon.

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

[0108] In this example, the elongate member 21 extends beyond the longitudinal end portion 10a of the aerosol-forming material 10. In other examples, the elongate member 21 may be in the same plane as the longitudinal end of the aerosol-forming material.

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

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

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

[0112] Device 200 may include an air inlet (not shown) that fluidly connects the heating zone 211 to the exterior of the device 200. Such an air inlet may be defined by the body 210. A user may be able to inhale an aerosol generated by the aerosol-generating material of article 100 by taking in the aerosol through the mouthpiece 102 of the article 100. When 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 body 210 comprises 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 protrusion, and may require mechanical engagement with the article for cooperation with or reception of the article. In this example, the heating zone 211 is elongate and sized and shaped to accommodate a portion of the article 100. In other examples, the heating zone 211 may be dimensioned to receive the entire article.

[0114] In this example, the magnetic field generator 212 comprises a power source 213, a coil 214, a device 216 for passing a varying 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 supply.

[0116] The coil 214 may be in any suitable form. In this example, the coil 214 is a helical coil of a conductive material such as copper. In some examples, the magnetic field generator 212 may include a ferromagnetic core around which the coil 214 is wound. Such a ferromagnetic core concentrates the magnetic flux generated by the coil 214 during use to generate a stronger magnetic field. The ferromagnetic core may be made of, for example, iron. In some examples, the ferromagnetic core may concentrate the magnetic flux in a specific region by extending only partially along the length of the coil 214. In some examples, the coil may be a flat coil. That is, the coil may be two-dimensionally helical. 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 may be oblique.

[0117] In this example, as shown in FIG. 10, when the article 100 is received in the recess 211, the longitudinal axis of the recess 211 substantially coincides with the longitudinal axis of the article 100. In this example, the impedance of the coil 214 of the magnetic field generator 212 is equal to the impedance of the coil 104 of the article 100. Or, substantially equal. As an alternative to this, if the impedance of the coil 104 of the 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 the article 100 during use will be lower than the voltage that could be generated in the coil 104 of the article 100 when the impedances match. Or, as an alternative to this, if the impedance of the coil 104 of the 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 the article 100 during use will be smaller than the current that could be generated in the coil 104 of the article 100 when the impedances match. Matching the impedances can help maximize the heating power generated in the coil 104 of the article 100 during heating in use, by balancing the voltage and current. The system 1000 of this example includes the article of FIG. 1, but in other examples, it may include the article shown in FIG. 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, a device 216 that passes a varying current through a coil 214 is electrically connected between a power source 213 and the coil 214. Also, in this example, a controller 217 is electrically connected to the power source 213 and communicably 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 includes an integrated circuit (IC) such as an IC on a printed wiring board (PCB). In other examples, the controller 217 may be in a different form. In some examples, the non-flammable aerosol supply device may have only one electrical or electronic component including the device 216 and the controller 217.

[0119] In this example, the controller 217 operates by a user operation of a user interface 218. In this example, the user interface 218 is disposed outside the main body 210. The user interface 218 may include a push button, a toggle switch, a dial, a touch screen, etc. In other examples, a user interface separated 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 a wireless communication method such as Bluetooth. For example, 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 a wireless communication method such as Bluetooth. The user may be able to remotely control the non-flammable aerosol supply device by using the user interface of each mobile phone.

[0120] In this example, by operating the user interface 218 by the user, the controller 217 causes the device 216 to pass an alternating current through the coil 214. As a result, the coil 214 generates an alternating magnetic field. The coil 214 and the heating zone 211 of the non-flammable aerosol supply device 200 are preferably arranged relative to each other such that when the article 100 is placed in the heating zone 211, the alternating magnetic field generated by the coil 214 penetrates the heating material of the article 100. In this example, the alternating magnetic field generated by the coil 214 penetrates the heating material of the coil 104.

[0121] In some examples, the heating material of the 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 in the heating material. The flow of the eddy current in the heating material with respect to the electrical resistance of the heating material causes the heating material to be heated by Joule heating. In some examples, the heating material is a magnetic material such as ferromagnetic stainless steel. In such examples, since the orientation of the magnetic dipoles in the heating material changes together with the applied alternating magnetic field, heat is generated in the heating material.

[0122] The non-combustible 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 the characteristics of the alternating or alternating current passing through the coil 214 as needed, so that the temperature of the heating zone 211 is maintained within a predetermined temperature range. This characteristic may be, for example, amplitude, frequency, or duty cycle. When used within the predetermined temperature range, at least one component of the aerosol-forming material volatilizes without combustion of the aerosol-forming material due to sufficient heating of the aerosol-forming material in the article disposed in the heating zone 211. Accordingly, the controller 217 (and the device 200 as a whole) is configured to volatilize at least one component of the aerosol-forming material by heating for aerosol generation without combustion of the aerosol generation. In some embodiments, the temperature range is from about 50°C to about 300°C, such as from about 50°C to about 250°C, from about 50°C to about 150°C, from about 50°C to about 120°C, from about 50°C to about 100°C, from about 50°C to about 80°C, or from about 60°C to about 70°C. In some embodiments, the temperature range is from about 170°C to about 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 maximum temperature at which it is desirable to heat the heating material, and further heating beyond this temperature due to inductive heating of the heating material is blocked or prevented.

[0123] Articles (e.g., in the shape of a rod) are often named according to the length of the product ("Regular" (usually in the range of 68 - 75 mm (e.g., about 68 mm - about 72 mm)), "Short" or "Mini" (less than 68 mm), "King Size" (usually in the range of 75 - 91 mm (e.g., about 79 mm - about 88 mm)), "Long" or "Super King" (usually in the range of 91 - 105 mm (e.g., about 94 mm - about 101 mm)), and "Ultra Long" (usually in the range of about 110 mm - about 121 mm)).

[0124] Also, they are named according to the outer perimeter of the product ("Regular" (about 23 - 25 mm), "Wide" (more than 25 mm), "Slim" (about 22 - 23 mm), "Demi Slim" (about 19 - 22 mm), "Super Slim" (about 16 - 19 mm), "Micro Slim" (less than about 16 mm)).

[0125] Thus, a King Size Super Slim type article would have, for example, a length of about 83 mm and an outer perimeter of about 17 mm.

[0126] Each type may be configured to be generated by mouthpieces of different lengths. The length of the mouthpiece is about 30 mm - 50 mm. The chip paper connects the mouthpiece to the aerosol - generating material and typically covers the mouthpiece and overlaps the aerosol - generating material (e.g., in the form of a rod of substrate material) such that it has a length greater than the mouthpiece (e.g., 3 - 10 mm longer) to connect the mouthpiece to the rod.

[0127] The articles described herein, as well as the respective aerosol - generating materials and mouthpieces, can be configured in any of the above - mentioned types, but are not limited thereto.

[0128] In some embodiments, the substance to be delivered may be an aerosol-forming material or a material that is not the subject of aerosolization. Any of these materials may optionally contain one or more active constituents, 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-forming material. In some embodiments, the aerosol generator is a heater configured to form an aerosol by releasing one or more volatile substances from the aerosol-forming material by applying thermal energy to the aerosol-forming material. In some embodiments, the aerosol generator is configured to generate an aerosol from the aerosol-forming material without heating. For example, the aerosol generator may be configured to apply one or more of vibration, high pressure, or electrostatic energy to the aerosol-forming material.

[0130] An aerosol-forming material is a material capable of generating an aerosol when supplied with energy, for example by heating, irradiation, or any other method. The aerosol-forming material may be in the form of, for example, a solid, liquid, or gel, and may or may not contain an active substance and / or a flavorant. In some embodiments, the aerosol-forming material may contain an "amorphous solid", which may alternatively be referred to as a "monolithic solid" (i.e., non-fibrous). In some embodiments, the amorphous solid may be a dry gel. An amorphous solid is a solid material capable of holding some fluid, such as a liquid, inside. In some embodiments, the aerosol-forming material may contain, 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 include one or more constituent substances capable of forming an aerosol. In some embodiments, the aerosol forming material may include one or more of 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, tributyrin, lauryl acetate, lauric acid, myristic acid, and propylene carbonate. The total amount of the aerosol forming material supplied may range from 10 wt% to 30 wt% (e.g., 12 wt% to 22 wt%) of the aerosol generating material such as tobacco material.

[0133] One or more other functional materials may include one or more of a pH adjuster, a colorant, a preservative, a binder, a filler, a stabilizer, and / or an antioxidant.

[0134] The material may be present on or in a 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 include these materials. In some embodiments, the support comprises a susceptor. In some embodiments, the susceptor is embedded in the material.
