Carrying out the invention

The term "aerosol-forming material" includes materials that produce volatile components when heated, usually in the form of vapor or aerosol. The "aerosol-forming material" may be a non-tobacco-containing material or a tobacco-containing material. The aerosol-forming material may, for example, include one or more of tobacco itself, tobacco derivatives, blasted tobacco, reconstituted tobacco, tobacco extract, homogenized tobacco, or tobacco substitutes. The aerosol-forming material may be in the form of ground tobacco, cut tobacco fiber, extruded tobacco, reconstituted tobacco, reconstituted aerosol-forming material, liquid, gel, gelatinized sheet, powder, pelleted products, or the like. The aerosol-forming material may also include other non-tobacco products which, depending on the product, may or may not contain nicotine. The aerosol-forming material may contain one or more wetting agents such as glycerin or propylene glycol.

In some embodiments, the aerosol-forming material comprises an “amorphous substance,” which may alternatively be referred to as a “monolithic solid” (ie, non-fibrous) or a “dried gel.” An amorphous substance is a solid material that can hold some amount of fluid, such as liquid. In some cases, such material contains from about 50, 60, or 70 weight percent amorphous material to about 90, 95, or 100 weight percent amorphous material. In some cases, the aerosol-forming material consists of an amorphous substance.

The amorphous substance may be formed into a sheet. It may be included in the consumable material in the form of a sheet. In some cases, the aerosol-forming material may be included in the form of a flat sheet, in the form of a bundled or assembled sheet, in the form of a corrugated sheet, or in the form of a rolled sheet (ie, in the form of a tube). In some such cases, the amorphous material may be included in the consumable or system in the form of a sheet, such as a sheet circumferentially surrounding a rod of aerosol-forming material (eg, tobacco). In some other cases, the aerosol-forming material may be formed into a sheet and then crushed and incorporated into a consumable product. In some cases, the shredded leaf may be mixed with cut tobacco fiber and included in the consumable product.

In some cases, the amorphous material may contain 1-60 wt.% gelling agent, these weights being calculated on a dry weight basis.

Preferably, the amorphous material may contain from about 1, 5, 10, 15, 20 or 25 wt.% to about 60, 50, 45, 40, 35, 30 or 27 wt.% gelling agent (all calculated on a dry weight basis) . For example, the amorphous material may contain 1-50 wt%, 5-40 wt%, 10-30 wt% or 15-27 wt% gelling agent.

In some embodiments, the gelling agent comprises a hydrocolloid. In some embodiments of the invention, the gelling agent contains one or more of the following compounds; alginates, pectins, starches (and their derivatives), celluloses (and their derivatives), gums, silica or silicon-containing compounds, clays, polyvinyl alcohol and combinations thereof. For example, in some embodiments, the gelling agent contains one or more of the following: alginates, pectins, hydroxyethylcellulose, hydroxypropylcellulose, carboxymethylcellulose, pullulan, xanthan gum, guar gum, carrageenan, agarose, acacia, fumed silica, polydimethylsiloxane (PDMS), sodium silicate, kaolin, and polyvinyl alcohol. In some cases, the gelling agent contains alginate and/or pectin, and may be combined with a setting agent (such as a calcium source) during formation of the amorphous substance. In some cases, the amorphous substance may contain calcium cross-linked alginate and/or calcium cross-linked pectin.

In some embodiments, the gelling agent comprises alginate, wherein the alginate is present in the amorphous material in an amount of from 10 to 30 weight percent of the amorphous material (on a dry weight basis). In some embodiments, the alginate is the only gelling agent present in the amorphous material. In other embodiments, the gelling agent comprises alginate and at least one additional gelling agent, such as pectin.

In some embodiments, the amorphous substance may include a gelling agent containing carrageenan.

Preferably, the amorphous material may contain from about 5, 10, 15, or 20 wt.% to about 80, 70, 60, 55, 50, 45, 40, or 35 wt.% aerosol-forming agent (all calculated on a dry weight basis). The aerosol-forming agent may act as a plasticizer. For example, the amorphous material may contain 5-60 wt.%, 10-50 wt.% or 20-40 wt.% aerosol-forming agent. In some cases, the aerosol-forming agent contains one or more of the following compounds; erythritol, propylene glycol, glycerin, triacetin, sorbitol and xylitol. In some cases, the aerosol-forming agent contains, or is essentially composed of, glycerol. It has been found that if the plasticizer content is too high, the amorphous substance may absorb water, resulting in a material that does not provide the proper feel when using the device. If the plasticizer content is too low, the amorphous substance may be brittle and easily break down. This plasticizer content provides the flexibility of the amorphous substance, which allows the sheet of this substance to be wound onto a bobbin, which is useful in the manufacture of aerosol generating products.

In some cases, the amorphous substance may contain a flavoring agent. Preferably, the amorphous material may contain up to about 60, 50, 40, 30, 20, 10, or 5 weight percent flavorant. In some cases, the amorphous material may contain at least about 0.1, 0.5, 1, 2, 5, 10, 20, or 30 weight percent flavor (all calculated on a dry weight basis). For example, the amorphous substance may contain 0.1-60 wt.%; 1-60 wt.%; 5-60 wt.%; 10-60 wt.%; 20-50 wt.% or 30-40 wt.% flavoring. In some cases, the flavor (if present) contains, consists of, or is substantially composed of menthol. In some cases, the amorphous substance does not contain flavoring.

In some cases, the amorphous substance contains the active substance. For example, in some cases, the amorphous substance contains tobacco material and/or nicotine. For example, the amorphous substance may contain powdered tobacco and/or nicotine and/or tobacco extract. In some cases, the amorphous material may contain from about 1, 5, 10, 15, 20, or 25 weight percent to about 70, 50, 45, or 40 weight percent (calculated on a dry weight basis) of active agent. In some cases, the amorphous material may comprise from about 1, 5, 10, 15, 20, or 25% by weight to about 70, 60, 50, 45, or 40% by weight (calculated on a dry weight basis) of the tobacco material and/or nicotine .

In some cases, the amorphous substance contains an active substance, such as tobacco extract. In some cases, the amorphous substance may contain 5-60% by weight (calculated on a dry weight basis) of tobacco extract. In some cases, the amorphous material may contain from about 5, 10, 15, 20, or 25 weight percent to about 55, 50, 45, or 40 weight percent (calculated on a dry weight basis) tobacco extract. For example, the amorphous substance may contain 5-60 wt.%; 10-55 wt.% or 25-55 wt.% tobacco extract. The tobacco extract may contain nicotine at a concentration such that the amorphous solid contains from 1, 1.5, 2 or 2.5 wt% to about 6, 5, 4.5 or 4 wt% (calculated on a dry weight basis) nicotine In some cases, the amorphous substance may not contain nicotine, except that which is formed from the tobacco extract.

In some embodiments, the amorphous substance does not contain tobacco material, but contains nicotine. In some such cases, the amorphous material may contain from about 1, 2, 3 or 4 wt.% to about 20, 15, 10 or 5 wt.% (calculated on a dry weight basis) nicotine. For example, the amorphous substance may contain 1-20 wt.% or 2-5 wt.% nicotine.

In some cases, the total active ingredient and/or flavoring content may be at least about 0.1, 1, 5, 10, 20, 25 or 30% by weight. In some cases, the total active and/or flavoring content may be no more than about 80, 70, 60, 50 or 40% by weight (all calculated on a dry weight basis).

In some cases, the total content of tobacco material, nicotine, and flavor may be at least about 1, 5, 10, 20, 25, or 30 weight percent. In some cases, the total content of tobacco material, nicotine and flavor may be no more than about 80, 70, 60, 50 or 40% by weight (all calculated on a dry weight basis).

In some cases, the amorphous material contains from about 1 to about 15 wt.% water, or from about 5 to about 15 wt.% based on wet weight. Preferably, the water content of the amorphous material can range from about 5, 7 or 9 wt.% to about 15, 13 or 11 wt.% (calculated based on wet weight), most preferably about 10 wt.%.

In some embodiments, the amorphous substance is a hydrogel and contains no more than about 20 weight percent water (calculated based on wet weight). In some cases, the hydrogel may contain no more than about 15, 12, or 10 weight percent water (calculated based on wet weight).

The amorphous substance may be made from a gel, and this gel may further contain a solvent in an amount of 0.1-50% by weight. However, it has been found that the inclusion of a solvent in which the flavor is dissolved can reduce the stability of the gel and the flavor may crystallize from the gel. In some cases, the gel does not substantially include a solvent in which the flavor can be dissolved.

In some embodiments, the amorphous substance contains less than 60 wt.% filler, for example, from 1 to 60 wt.%, or from 5 to 50 wt.%, or from 5 to 30 wt.%, or from 10 to 20 wt. %.

In other embodiments of the invention, the amorphous substance contains less than 20 wt.%, preferably less than 10 wt.% or less than 5 wt.% filler. In some cases, the amorphous material contains less than 1 wt.% filler, and in some cases contains no filler at all.

The filler, filler is present, it may contain one or more inorganic materials such as calcium carbonate, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, magnesium carbonate and suitable inorganic sorbents such as molecular sieves. The filler may contain one or more organic materials such as wood pulp, cellulose and cellulose derivatives. In specific cases, the amorphous substance does not contain calcium carbonate, such as chalk.

In particular embodiments of the invention that include filler, the filler is fibrous. For example, the filler may be a fibrous organic filler such as wood pulp, hemp fiber, cellulose or cellulose derivatives. Incorporating a fibrous filler into the amorphous material can increase the tensile strength of the material. This may be particularly advantageous in cases where the amorphous material is in the form of a sheet, for example when a sheet of amorphous material surrounds a rod of aerosol-forming material.

In some embodiments, the amorphous substance does not contain tobacco fibers. In certain embodiments, the amorphous solid does not contain fibrous material.

In some embodiments, the aerosol-forming material does not contain tobacco fibers. In certain embodiments of the invention, the aerosol-forming material does not contain fibrous material.

In some embodiments, the aerosol-forming base does not contain tobacco fibers. In certain embodiments, the aerosol-forming body does not contain fibrous material.

In some embodiments, the aerosol generating article does not contain tobacco fibers. In certain embodiments, the consumable material does not contain fibrous material.

In some cases, the amorphous substance may consist or consist essentially of a gelling agent, an aerosolizing agent, a tobacco material and/or a nicotine source, water, and optionally a flavoring agent.

A method of making an aerosol-forming material may comprise (a) forming a suspension containing components of the amorphous substance or its starting components, (b) forming a layer of suspension, (c) curing the suspension to form a gel, and (d) drying to form the amorphous substance.

Step (b) of forming the slurry layer may comprise, for example, spraying, molding or extruding the slurry. In some cases, the layer is formed by electrospraying a suspension. In some cases, the layer is formed by molding the slurry using a molding chamber.

In some cases, the suspension is applied to a carrier.

In some cases, steps (b) and/or (c) and/or (d) may be at least partially performed simultaneously (eg, during electrospray). In some cases, these steps may be performed sequentially.

Step (c) of curing the gel may comprise adding a curing agent to the suspension. For example, the suspension may contain sodium, potassium or ammonium alginate as gel starting components, and a setting agent containing a source of calcium (such as calcium chloride) may be added to the suspension to form a calcium alginate gel.

The total amount of curing agent, such as a calcium source, may be 0.5-5 wt.% (calculated on a dry weight basis). It has been found that adding too little curing agent can result in the formation of an amorphous substance that does not stabilize the amorphous solid components and causes these components to precipitate from the amorphous substance, while adding too much curing agent results in an amorphous substance that is very sticky and therefore difficult to process.

Alginate salts are derivatives of alginic acid and are typically high molecular weight polymers (10 - 600 kDa). Alginic acid is a copolymer of β-D-mannuronic (M) and α-L-guluronic acid (G) units (blocks) linked together by (1,4)-glycosidic bonds to form a polysaccharide. When calcium cations are added, the alginate cross-links to form a gel. The inventors have determined that alginate salts with high G-monomer content gel more easily when a calcium source is added. Therefore, in some cases, the precursor gel contains an alginate salt in which at least about 40, 45, 50, 55, 60, or 70% of the monomer units in the alginate copolymer are α-L-guluronic acid (G) units.

The drying step may cause the thickness of the cast material to be reduced by at least 80%, preferably 85% or 87%. For example, the suspension may be cast at a thickness of 2 mm, and the resulting dried amorphous material may be 0.2 mm thick.

In some cases, the thickness of the amorphous material may be from about 0.015 to about 1.0 mm. Preferably, the thickness may range from about 0.05, 0.1 or 0.15 mm to about 0.5 or 0.3 mm. It has been found that 0.2 mm thick material is particularly suitable. The amorphous substance may contain more than one layer, and the above thickness refers to the total thickness of these layers.

In some cases, the solvent of the suspension may consist or essentially consist of water. In some cases, the suspension may contain from about 50, 60, 70, 80 or 90 wt.% solvent (calculated based on wet weight).

If the solvent consists of water, the dry weight content of the suspension may correspond to the dry weight content of the amorphous substance.

In some examples, the slurry has a viscosity of about 10 to about 20 Pa.s at 46.5°C, such as about 14 to about 16 Pa.s at 46.5°C.

The aerosol-forming material containing the amorphous material may have any suitable areal density, for example, from 30 to 120 g/m ² . In some embodiments, the aerosol-forming material may have a basis weight of from about 30 to 70 g/m ² , or from about 40 to 60 g/m ² . In some embodiments, the amorphous material may have a basis weight of from about 80 to 120 g/m ² , or from about 70 to 110 g/m ² , or, in particular, from about 90 to 110 g/m ² . Such area densities are particularly suitable when the aerosol-forming material is included in the consumable or system in sheet form or in the form of crushed sheet (further described below).

In some examples, the amorphous sheet-shaped material may have a tensile strength of from about 200 to about 900 N/m. In some examples, for example, when the amorphous material contains no filler, the amorphous material may have a tensile strength of 200 to 400 N/m, or 200 to 300 N/m, or about 250 N/m. Such tensile strength values are particularly suitable for embodiments of the invention in which the aerosol-forming material is formed into a sheet and then crushed and included in the consumable composition. In some examples, for example, when the amorphous substance contains a filler, the amorphous substance may have a tensile strength of from 600 to 900 N/m, or from 700 to 900 N/m, or about 800 N/m. Such tensile strength values are particularly suitable for embodiments of the invention in which the aerosol-forming material is included in the consumable composition or system in the form of a rolled sheet, preferably in the form of a tube.

In one particular case, the carrier may be a paper-based foil. In this case, the paper layer is adjacent to the layer of an amorphous substance, due to which the properties described above are ensured. The paper-based foil is substantially impermeable, providing control of the aerosol flow path. Paper-backed metal foil can also transfer heat to an amorphous substance.

In another case, a metallic foil layer on a paper base is adjacent to an amorphous substance. The foil is substantially impermeable, which prevents the absorption of water contained in the amorphous material into the paper, which would weaken its structural integrity.

In some cases, the carrier is formed from or contains metal foil, such as aluminum foil. The metal carrier can provide better transfer of thermal energy to the amorphous substance. Additionally or alternatively, the metal foil can act as a current collector in an induction heating system. In particular embodiments of the invention, the carrier comprises a layer of metal foil and a support layer, for example a layer of cardboard. In these embodiments, the thickness of the metal foil layer may be less than 20 microns, for example, from about 1 to about 10 microns, preferably about 5 microns.

The term "sheet" as used means an element whose width and length are significantly greater than its thickness. The sheet can be, for example, a strip.

The term "heating material" or "heater material" as used refers to a material that is capable of heating when a changing magnetic field is introduced into it.

Induction heating is a process in which an electrically conductive object is heated when a changing magnetic field penetrates it. The process is described by Faraday's law of induction and Ohm's law. The induction heater may include an electromagnet and means for passing a varying electrical current, such as alternating current, through the electromagnet. When an electromagnet and an object to be heated are positioned appropriately relative to each other such that the resulting changing magnetic field generated by the electromagnet penetrates the object, one or more eddy currents are generated within the object. An object has resistance to electric current, therefore, when eddy currents occur in the object, heating of the object occurs. This process is called Joule, ohmic or resistive heating. An object that can be subjected to induction heating is called a sensing element.

It has been found that if the sensing element is in the form of a closed electrical circuit, the magnetic coupling between the sensing element and the electromagnet used is enhanced, resulting in greater or enhanced Joule heating.

Magnetic hysteresis heating is a process in which an object made of magnetic material heats up due to the penetration of an alternating magnetic field into the object. The magnetic material can be considered to contain a plurality of atomic-scale magnets or magnetic dipoles. When a magnetic field penetrates such a material, the magnetic dipoles align with the magnetic field, therefore, when a changing magnetic field, such as an alternating magnetic field produced by an electromagnet, penetrates a magnetic material, the orientation of the magnetic dipoles changes along with the changing magnetic field. This reorientation of magnetic dipoles causes the release of heat in the magnetic material.

When an object is both electrically conductive and magnetic, the penetration of an alternating magnetic field into it can cause both Joule and magnetic hysteresis heating of the object. In addition, the use of magnetic material can enhance the magnetic field, which also increases Joule and magnetic hysteresis heating.

In each of the above processes, since the heat is generated within the object itself rather than coming from an external heat source through conduction, a rapid increase in temperature within the object and a more uniform distribution of heat can be achieved, particularly through the selection of suitable object material and geometry, and also the appropriate magnitude of the changing magnetic field and its orientation relative to the object. Additionally, because induction and magnetic hysteresis heating do not require a physical connection between the alternating magnetic field source and the object, design freedom is increased and control of the heating profile is improved, while product costs can be reduced.

In fig. 1 and 2 show a consumable in accordance with one embodiment of the invention. Consumable material 1 is for use with an aerosol-forming material heating device to vaporize at least one component of the aerosol-forming material, such as device 100 shown in FIG. 5 and described below. The device may be a device for heating a tobacco product (also known as a device for heating tobacco or heating without combustion.

The consumable material 1 includes a hollow tube 1a, which defines an internal channel 20 located therein. The hollow tube 1a contains a wound structure 10 containing an aerosol-forming material. In this embodiment of the invention, the wound structure 10 is a helically wound structure containing an aerosol-forming material. However, in other embodiments of the invention, the wound structure may be non-helical wound. For example, the structure containing the aerosol-forming material may be wound in a non-helical manner.

In some embodiments, the aerosol-forming material of structure 10 comprises tobacco. In some embodiments, the aerosol-forming material comprises a reconstituted aerosol-forming material, such as reconstituted tobacco. In some embodiments, the aerosol-forming material comprises an amorphous substance, which may, for example, be supported on a carrier such as paper or cardboard. In other embodiments, the aerosol-forming material may be in any of the other forms discussed herein. The structure containing the aerosol-forming material may comprise a carrier such as paper or cardboard, and the aerosol-forming material may be on the surface of the carrier or impregnate the carrier. For example, the aerosol-forming material may contain tobacco extract. In some embodiments of the invention, the structure containing the aerosol-forming material consists of an aerosol-forming material. For example, the aerosol-forming material may be cast or otherwise formed.

In this embodiment, the wound structure 10 containing the aerosol-forming material defines both the innermost surface 1b of the hollow tube 1a and the outermost surface 1c of the hollow tube 1a. In some embodiments of the invention, the hollow tube 1a consists or essentially consists of a wound structure 10 containing an aerosol-forming material. In other embodiments of the invention, as will be understood from the following description, the innermost surface 1b of the hollow tube 1a and/or the outermost surface 1c of the hollow tube 1a may be defined by a consumable portion other than the wound structure 10 containing an aerosol-forming material. The portion may be another layer of the hollow tube 1a or a consumable. In some embodiments, the wound structure 10 containing the aerosol-generating material defines only a portion of the innermost surface 1b of the hollow tube 1a and/or only a portion of the outermost surface 1c of the hollow tube 1a due to the presence of another portion of the hollow tube 1a or a consumable portion delimiting, respectively, part or all of the remaining part of the innermost and/or outermost surface.

In this embodiment of the invention, the structure 10 containing the aerosol-forming material is circular. In other embodiments, the wound structure 10 containing the aerosol-generating material is corrugated, embossed, or embossed. Such an arrangement may increase the surface area on which an aerosol can be generated from the aerosol-forming material when the device is used.

In fig. 3 and 4 show a consumable 2 according to another embodiment of the invention. The consumable material 2 is intended for use in a device for heating an aerosol-forming material to vaporize at least one component of the aerosol-forming material, such as the device 100 shown in FIG. 5 and described below. The device may be a tobacco heating product (also known as a tobacco heating device or a non-combustion heating device).

The consumable 2 contains a hollow tube 2a. The hollow tube 2a defines an internal channel 20 located therein. The hollow tube 2a contains a plurality of layers 10, 11, 12, 13. In some embodiments, two layers, or some layers, or all layers of a plurality of layers 10, 11, 12, 13 bonded together, resulting in multiple layers forming a layered structure.

One of the layers is a wound structure 10 containing an aerosol-forming material. In this embodiment of the invention, the wound structure 10 is a helically wound structure containing an aerosol-forming material. However, in other embodiments of the invention, the wound structure may be non-helical wound. For example, the structure containing the aerosol-forming material may be wound in a non-spiral manner.

In some embodiments, the aerosol-forming material of structure 10 comprises tobacco. In some embodiments, the aerosol-forming material is a reconstituted aerosol-forming material, such as reconstituted tobacco. In some embodiments, the aerosol-forming material comprises an amorphous substance, which may, for example, be supported on a carrier such as paper or cardboard. The structure containing the aerosol-forming material may comprise a carrier such as paper or cardboard, and the aerosol-forming material may be on the surface of the carrier or impregnate the carrier. For example, the aerosol-forming material may contain tobacco extract. In some embodiments of the invention, the structure containing the aerosol-forming material consists of an aerosol-forming material. For example, the aerosol-forming material may be cast or otherwise formed.

In this embodiment of the invention, a wound structure 10 containing an aerosol-forming material defines the surface of the hollow tube 2a, in particular its innermost surface 2b. In other embodiments of the invention, the wound structure 10 containing the aerosol-forming material defines only a portion of the innermost surface 2b of the hollow tube 2a because another portion of the hollow tube 2a or consumable defines some or all of the remaining portion of the innermost surface 2b.

In this embodiment of the invention, the wound structure 10 containing the aerosol-forming material contains corrugations. In other embodiments of the invention, the structure 10 additionally or alternatively includes embossing or embossing. As mentioned above, this arrangement allows for an increase in the surface area on which an aerosol can be generated from the aerosol-generating device when the device is used. In other embodiments, the wound structure 10 containing the aerosol-generating material is not corrugated, embossed, or embossed.

As noted above, the hollow tube 2a contains additional layers 11, 12, 13. It should be noted that not all of these additional layers 11, 12, 13 may be present in all embodiments of the invention. In this embodiment, each of the additional layers 11, 12, 13 is a wound layer, such as a helically wound layer, but in other embodiments, one or more additional layers 11, 12, 13 may be a non-wound layer, such as as a cast or extruded layer.

In this embodiment of the invention, the consumable 2 contains a heating material capable of being heated under the influence of a changing magnetic field. The heating material may be, for example, one or more of the materials listed above. The heating material is designed to heat the aerosol-forming material of the wound structure 10. In this embodiment, the hollow tube 2a includes a heating material layer 11. More specifically, the layer 11 containing the heating material is radially adjacent to the wound structure 10 containing the aerosol-forming material, whereby the thermal energy generated in the heating material when the device is used can be effectively transferred to the aerosol-forming material. In this embodiment, the layer 11 containing the heating material is located radially outward from the wound structure 10 containing the aerosol-forming material, but in other embodiments of the invention, the layer 11 containing the heating material may be located radially inward from the wound structure 10 containing the aerosol-forming material .

In this embodiment of the invention, the layer 11 containing the heating material is a wound layer, such as a helically wound layer, wherein the layer 11 containing the heating material is wound around a structure 10 containing the aerosol-forming material. In other embodiments of the invention, the layer 11 containing the heating material may not be wound. In some embodiments of the invention, the heating material containing layer 11 includes a carrier, such as paper, carrying the heating material. In other embodiments of the invention, the layer 11 containing the heating material comprises a metal or metal alloy foil, such as aluminum. In some embodiments of the invention, the layer 11 containing the heating material may be absent. In some embodiments of the invention, the consumable part 2 may not contain a heating material capable of heating when a changing magnetic field penetrates it.

In this embodiment, the aerosol-forming material of the wound structure 10 adheres the wound structure 10 to the layer 11 containing the heating material. In other embodiments, this may not be the case and/or the aerosol-forming material of the wound structure 10 may adhere the wound structure 10 to another layer or portion of the hollow tube 2a. In some embodiments of the invention, an adhesive may be used to glue the layers together.

As noted above, in this embodiment, in this embodiment, the structure 10 containing the aerosol-forming material includes corrugations, and in some other embodiments, the structure 10 additionally or alternatively includes embossing or embossing. The hollow tube 2a in this case contains one or more aerosol flow paths 17 defined by and between the corrugations, embossing or extrusion of the structure 10 containing the aerosol-forming material and the layer 11 containing the heating material. The aerosol flow path(s) extend in the axial direction of the hollow tube 2a and provide a route along which aerosol generated in or from the aerosol-forming material can exit the hollow tube 2a. This may be particularly advantageous if the inner channel 20 of the consumable 2 is filled with a heating element of the device with which the consumable 2 can be used. In other embodiments of the invention, whereby the hollow tube 2a is free of heating material, one or more aerosol flow paths may be formed between the corrugations, embossing or extrusion of the structure containing the aerosol-forming material and another layer or part of the hollow tube 2a, such as another layer 12 or a barrier layer 13, which will be described below.

In this embodiment of the invention, the hollow tube 2a includes a barrier layer 13 defining the surface of the hollow tube 2a. In this embodiment, said surface is the outermost surface 2c of the hollow tube 2a, therefore, the barrier layer 13 is located radially outside the wound aerosol-forming material structure 10. In addition, a layer 11 containing a heating material is located between the barrier layer 13 and the structure 10 containing the aerosol-forming material, and is adjacent to this structure 10. In some embodiments of the invention, the barrier layer 13 defines only a portion of the outermost surface 2c of the hollow tube 2a, t .To. another portion of the hollow tube 2a or consumable defines some or all of the remainder of the outermost surface 2c. In some embodiments, the barrier layer 13 is a wound layer, such as a helical wound layer, but in other embodiments, the barrier layer 13 may be a non-wound layer.

The barrier layer 13 may, for example, comprise one or more of the following materials: paper, cardboard, paperboard, paperboard, reconstituted tobacco, plastic material, or heating material. The barrier layer 13 helps provide rigidity to the hollow tube 2a. In some embodiments of the invention in which the barrier layer 13 is adjacent to a structure 10 containing an aerosol-generating material, the barrier layer 13 is impermeable to the aerosol generated in the structure 10 during use of the device. This may prevent or prevent the generated aerosol from contacting the device, or depositing it in the device with which the consumable material 2 is used. It also helps direct the aerosol generated from the aerosol-generating material along and beyond the hollow tube 2a. In some embodiments of the invention, the barrier layer 13 is absent.

The consumable material 2 in this embodiment of the invention includes another layer 12 that is radially adjacent to the layer 11 containing the heating material, whereby the thermal energy generated in the heating material when using the device can be effectively transferred to the other layer 12. In this case, the layer 11 containing the heating material is located radially inward relative to the other layer 12, but in other cases the layer 11 containing the heating material may be located radially outward from the other layer 12. Thus, in this case, the other layer 12 is located between the barrier layer 13 and layer 11 containing heating material and also adjacent to the barrier layer 13.

In some embodiments, another layer 12 contains an aerosol-forming material. Thus, in some such embodiments, the hollow tube 2a includes a layer 11 containing a heating material that is located between a wound structure 10 containing an aerosol-forming material and another layer 12 containing an aerosol-forming material. The aerosol-forming material of the other layer 12 may adhere the other layer 12 to the barrier layer 13 and/or to the heating material-containing layer 11. In some embodiments, the aerosol-forming material of the other layer 12 contains tobacco. In some embodiments, the aerosol-forming material is a reconstituted aerosol-forming material, such as reconstituted tobacco. In some embodiments, the aerosol-forming material comprises an amorphous substance, which may, for example, be supported on a carrier such as paper or cardboard. In some embodiments, in addition to or alternatively to the aerosol-forming material, another layer 12 may contain, for example, a flavoring agent or a sensory substance. In some embodiments of the invention, the other layer 12 is absent.

In some embodiments, the other layer 12 is a wound layer, such as a helical wound layer, but in other embodiments, the other layer 12 may be a non-wound layer. In some embodiments, another layer 12 is wound around a layer 11 containing a heating material, or around any other layer located radially inward relative to another layer 12. Likewise, in some embodiments, a barrier layer 13 is wound around another layer 12.

In some embodiments, the aerosol-forming material of the other layer 12 has a different shape or chemical composition than the aerosol-forming material of the structure 10. For example, in some embodiments, a difference in shape may mean a difference in the average particle size of the aerosol-forming material. In general, particles of aerosol-forming material of a smaller average size may be heated faster, for example, to vaporize at least one component of the aerosol-forming material, than particles of aerosol-forming material of a larger average size under the same heat source.

In some embodiments, the difference in shape may relate to the aerosol-forming material of the structure 10 or layer 12 being in the form of a reconstituted aerosol-forming material (such as reconstituted tobacco) and the aerosol-forming material of another structure 10 or layer 12 containing an amorphous substance.

In some embodiments, a difference in chemical composition may mean a difference in the ingredient or ingredients of the aerosol-forming material, for example, a difference in the chemical composition of the respective amorphous substances. In some embodiments, a difference in chemical composition may mean a difference in the type or density of aerosol-forming agent, such as glycerin, in the aerosol-forming material. In some embodiments, a difference in chemical composition may mean a difference in the amounts by weight of a smoke modifying agent, such as a flavoring agent, as a percentage of the total weight of the aerosol-forming material.

In some embodiments, the layer 12 (if present) and/or the wound structure 10 containing the aerosol-forming material may comprise a plurality of spaced apart discrete regions of the aerosol-forming material. When the device is used, such discrete areas of the aerosol-forming material can be independently heated by the corresponding heaters of the device with which the consumable 2 is used.

Accordingly, as noted above, in some embodiments of the invention, the plurality of layers 10, 11, 12, 13 of the hollow tube 2a may be layer wound, with the outer layers of layers 11, 12, 13 wound around the inner layers 10, 11, 12. Methods The manufacture of such hollow tubes 2a will be discussed below.

In some embodiments of the invention, the order of the layers 10, 11, 12, 13 of the hollow tube 2a may differ from that shown in FIG. 3 and 4. For example, in some embodiments of the invention, the consumable material may have a wound structure containing an aerosol-forming material that forms at least a portion of the outermost surface of the hollow tube, and a layer containing heating material that is located radially inward from the structure containing the aerosol-forming material. material.

In some embodiments of the invention, the hollow tube 2a may comprise at least one additional layer, which may or may not be a wound layer, for example a spiral wound layer.

In each of the embodiments of FIGS. 1-4, the hollow tube 1a, 2a has a circular cross-sectional shape for the inner and outer portions of the tube. In other embodiments, one or each of the inner and outer cross-sectional shapes of the hollow tube may be non-circular, such as elliptical, polygonal, rectangular, square, triangular or star-shaped.

In each of the embodiments discussed above, the hollow tube 1a, 2a extends along the axis A-A. The A-A axis is a central axis that extends along the inner channel 20, but in other embodiments, the configuration of the consumable 1, 2 may be such that the A-A axis is offset relative to the inner channel 20. In the illustrated embodiments, the consumable 1, 2 has an elongated shape in the A-A axis direction, but in other embodiments, the width or diameter of the consumable 1, 2 may be greater than or equal to the size of the consumable 1, 2 in the A-A axis direction, so that the consumable 1, 2 is not elongated. Moreover, in the illustrated embodiments, the hollow tube 1a, 2a of the consumable 1, 2 has an elongated shape in the A-A axis direction, but in other embodiments, the width or diameter of the hollow tube 1a, 2a may be greater than or equal to the size of the hollow tube 1a. 2a in the direction of the A-A axis, so that the hollow tube 1a, 2a is not itself elongated.

In each of the embodiments of FIGS. 1-4, the internal channel 20 is open at the axial end 15 of the hollow tube 1a, 2a and, in fact, at the end of the consumable 1, 2. In some embodiments of the invention, in which the consumable does not contain heating material, the heating element of the device can be inserted into the internal channel 20 when using the device as will be described in more detail below. In each of the embodiments of FIGS. 1-4, the inner channel 20 extends completely through the hollow tube 1a, 2a from one axial end 15 thereof to the opposite axial end 16. Moreover, in each of these embodiments, the inner channel 20 extends completely through the consumable 1, 2 from its first axial end 15 to the opposite second axial end 16. However, in some embodiments of the invention, the inner channel 20 may extend only partially along the length or axial dimension of the consumable 1, 2, for example, through most of the length or axial dimension of the consumable 1, 2, or to a smaller part of the length or axial size of the consumable material 1, 2.

In some embodiments, the hollow tube 1a, 2a extends the entire length or axial dimension of the consumable 1, 2. In other embodiments, the consumable 1, 2 may include one or more elements (not shown) at one or each axial end of the hollow tubes 1a, 2a, so that the hollow tube 1a, 2a extends only part of the length or axial dimension of the consumable 1, 2.

In some embodiments, the consumable material 1, 2 comprises a porous body (not shown). The porous body is designed to filter the aerosol or vapor released from the aerosol-forming material when the device is used. Alternatively or additionally, the porous body may be configured to control a pressure differential along the length or axial dimension of the consumable material 1, 2. The porous body may be of any type used in the tobacco industry. For example, the porous body may be made of cellulose acetate. In some embodiments of the invention, the porous body is substantially cylindrical with a substantially circular cross section and longitudinal axis. In other embodiments, the filter may have a different cross-section or not be elongated.

In some embodiments, the porous body is adjacent to the axial end 15, 16 of the hollow tube 1a, 2a and is axially aligned with the hollow tube 1a, 2a. In other embodiments of the invention, the porous body may be spaced from the hollow tube 1a, 2a, for example, by a gap and/or by one or more additional consumable components 1, 2. Examples of additional components include an additive or flavoring source (such as a capsule or threads containing an additive or flavoring) which may be retained, for example, by a porous body of filter material, or between two bodies of filter material.

The consumable 1, 2 may also include a wrapper that is wrapped around the hollow tube 1a, 2a and the porous body to hold the porous body relative to the hollow tube 1a, 2a. The wrapper may cover the hollow tube 1a, 2a and the porous body. The wrapper may be wrapped around the hollow tube 1a, 2a and the porous body such that the free ends of the wrapper overlap each other. The wrapper may form part or all of the circular outer surface of the consumable material 1, 2. The wrapper may be made from any suitable material, such as paper, cardboard, or reconstituted aerosol-forming material (eg, reconstituted tobacco). The wrapper may also contain an adhesive that glues the overlapping free ends of the wrapper together. The glue helps prevent the overlapping free ends of the wrapper from separating. In other embodiments, the adhesive may be missing or the wrapper may differ from that described. In other embodiments of the invention, the porous body may be held relative to the hollow tube 1a, 2a by a connector other than a wrapper, such as adhesive.

In some embodiments of the invention, the length or axial dimension of the consumable material 1, 2 is from 30 to 150 mm, for example, from 70 to 120 mm.

In some embodiments, the consumable material 1, 2 may have an internal dimension (eg, internal diameter) in a direction perpendicular to the axial direction of 2 to 10 mm, such as 4 to 8 mm.

In some embodiments, the consumable material 1, 2 has an outer dimension (eg, outer diameter) in a direction perpendicular to the axial direction of 4 to 10 mm, such as 4.5 to 8 mm.

In some embodiments, the aerosol-forming material, wherever located in the consumable material 1, 2, has a thickness of 0.05 to 2 mm, for example, 0.05 to 1 mm, or 0.1 to 1 mm, or from 0.15 to 0.5 mm. The thickness may be less than or equal to 1 mm, for example less than or equal to 0.5 mm, less than or equal to 0.25 mm, less than or equal to 0.2 mm, less than or equal to 0.1 mm or less than or equal to 0.05 mm .

As noted above, the wound structure, which may contain an aerosol-forming material, may include corrugations, embossing or embossing. In some such cases, corrugations, embossing or embossing define a plurality of depressions or depressions, and an aerosol-forming material (such as the amorphous substance described above) is located in at least one of the plurality of depressions or depressions.

Next, exemplary embodiments of methods for manufacturing a hollow tube as a consumable material for use in a device for heating an aerosol-forming material for vaporizing at least one component of the material will be described. Any of the methods described below can be used, for example, in the manufacture of any of the hollow tubes described above.

In fig. 6 shows a flow diagram of a method 600 for manufacturing such a hollow tube, whereby a structure 601 containing an aerosol-forming material is wound.

The aerosol-forming material may be, for example, any of those described above. In some embodiments, the aerosol-forming material comprises tobacco. In some embodiments, the aerosol-forming material is a reconstituted aerosol-forming material, such as reconstituted tobacco. In some embodiments, the aerosol-forming material comprises an amorphous substance, which may, for example, be supported on a carrier such as paper or cardboard. The structure containing the aerosol-forming material may contain a carrier such as paper or cardboard, and the aerosol-forming material may be on the surface of the carrier or impregnate the carrier. For example, the aerosol-forming material may contain tobacco extract. In some embodiments of the invention, the structure containing the aerosol-forming material consists of an aerosol-forming material. For example, the aerosol-forming material may be cast or otherwise formed.

In some embodiments, the winding 601 comprises a helically wound structure containing an aerosol-forming material. In some embodiments, the winding 601 comprises a helically wound structure containing an aerosol-forming material. In some embodiments, the winding 601 is a helical winding of a structure containing an aerosol-forming material such that the structure is in the shape of a helical helix.

Winding 601 may be accomplished by winding a structure containing an aerosol-forming material around a mandrel. The mandrel may be made of any suitable material, such as metal, a metal alloy, or a plastic material such as polyetheretherketone (PEEK). Alternatively, the mandrel may not be used. For example, the structure containing the aerosol-forming material may be wound using a headset. If the structure containing the aerosol-forming material contains corrugations, embossings or embossings, the surface of the mandrel may be suitably shaped to engage the corrugations, embossings or embossings.

In some embodiments, winding 601 includes winding a structure containing an aerosol-forming material to form the innermost surface of the hollow tube. In other embodiments, the structure containing the aerosol-forming material may be wound around one or more other elements of the hollow tube being manufactured, such as one or more helically wound layers, such that the structure containing the aerosol-generating material does not form the innermost surface of the hollow tube.

In some embodiments of the invention, the aerosol-forming material-containing structure comprises the aerosol-forming material on the surface of a medium, such as paper. In some such embodiments, the method includes wrapping a carrier and an aerosol-forming material around a mandrel, with the carrier in contact with the mandrel and the aerosol-forming material outermost therefrom, and then wrapping a layer, such as paper, onto the aerosol-forming material. This forms an arrangement in which the aerosol-forming material is sandwiched between the carrier and the layer.

In fig. 7 is a flow diagram of another method 700 for making a hollow tube for use in a device as a consumable part. Method 700 draws 701 material from its source, such as a reel or reel. The material can be, for example, paper or cardboard. The method also includes a step 702 of winding the material as it is pulled from the source. The winding 702 may be, for example, helical. Winding 702 may include winding material onto a mandrel. The mandrel can be made, for example, from any of the materials described above.

In some embodiments of the invention, the material drawn from its source already has an aerosol-forming material on it or within it. However, in some alternative embodiments of the invention, the method comprises the step 703 of applying an aerosol-forming material to the material after it has been drawn from the source. The aerosol-forming material may be any of those described above. The application step 703 may be performed before the location at which the material winding step 702 is performed. Alternatively, if the winding step 702 includes winding the material around a mandrel, the application step 703 may be performed using the mandrel. For example, the aerosol-forming material may be passed, eg, pumped, as a fluid through the mandrel and come into contact with the material while the material is on the mandrel. The mandrel may include a first portion around which the material is wound, and a second portion located downstream of the first portion and including openings for supplying aerosol-forming material through which the aerosol-forming material comes into contact with the material. The first part of the mandrel may not have holes for supplying aerosol-forming material. The material may be porous or non-porous with respect to the aerosol-forming material. After step 703 of applying the aerosol-forming material to the material, the material carrying the aerosol-forming material continues to be wound onto the mandrel.

In some embodiments, the aerosol-forming material may be applied to the outer surface of the mandrel or to a material on the mandrel or upstream of the mandrel without first passing through the mandrel. With this application, the aerosol-forming material can be in the form of a suspension.

The method may further comprise the step 704 of drying the aerosol-forming material during or after the step 702 of winding the structure.

In some embodiments of the invention, the structure containing the aerosol-forming material consists of an aerosol-forming material. The aerosol-forming material may be cast or otherwise formed. For example, the aerosol-forming material may be cast as a block and then compressed into a thinner form, such as a layer or sheet.

The structure containing the aerosol-forming material may, for example, include corrugations, embossings or embossings while it is at the source, or the structure may be passed through a station where the structure is formed with corrugations, embossings or embossings after the structure has been drawn from its source.

The method may also include the step 705 of winding one or more layers, for example, in a helical manner. In winding, one or more layers may be wound around a mandrel. One or more layers may be wound around a structure containing an aerosol-forming material. Alternatively, the structure containing the aerosol-forming material may be wound around one or more layers. In some embodiments, the structure containing the aerosol-forming material may be wound around one or more layers, and then one or more additional layers may be wound around the structure containing the aerosol-forming material.

At least one of the layers may contain a heating material capable of heating when a varying magnetic field penetrates it. The heating material may be, for example, any of the above. At least one of the layers may contain a flavor or sensory substance. At least one of the layers may contain an aerosol-forming material. The aerosol-forming material may be, for example, any of the above.

If a mandrel is used, in some embodiments of the invention the mandrel can be considered to have different zones: one in which the aerosol-forming material is applied to the material to form a structure containing the aerosol-forming material, one in which the structure is wound, one in which the aerosol-forming material is dried or allowing it to dry, and optionally one or more zones in which one or more layers can be wound around a structure containing the aerosol-forming material.

In some embodiments, different materials or layers may be wound around a mandrel from diametrically opposed sides of the mandrel. These various materials can be wound around the mandrel in a certain general area in the direction of the length of the mandrel. Each of the materials or layers may be, for example, any of the types mentioned above.

In some embodiments of the invention, to reduce adhesion of the aerosol-forming material to the mandrel, the aerosol-forming material may be coated with or contain a release agent. Alternatively or additionally, the mandrel may be coated with a release agent, or may be heated, or may be cone-shaped, or include a blower or ultrasonic vibrator to prevent the aerosol-forming material from sticking to the mandrel, or to assist in releasing the aerosol-forming material from the mandrel if it does stick. . The gas blower may include one or more openings on the surface of a mandrel upon which an aerosol-forming material or material is wound in use, as well as a source of gas, such as air, for supplying it to the one or more openings on the surface of the mandrel. In some embodiments of the invention, the mandrel may be made of a porous material, and gas may be supplied from its source to the surface of the mandrel through pores in the mandrel.

The method may result in the formation of a continuous hollow tube. The continuous hollow tube may be pulled from the mandrel during or after the winding step. In this case, the method may include a separation step 706, for example, by cutting a continuous hollow tube to form individual hollow tubes that can be included in a consumable, or forming a consumable for use in an aerosol-forming material heating device to vaporize at least one component this aerosol-forming material.

When producing the hollow tube 2a shown in FIG. 3 and 4, a winding step 702 may include winding material to form the innermost surface of the hollow tube, and a layer winding step 705 may include winding a layer containing a heating material around a structure containing an aerosol-forming material, winding another layer containing an aerosol-forming material material around a layer containing a heating material, and winding a barrier layer around another layer containing an aerosol-forming material.

In another embodiment of the invention, the method may comprise the step of applying an aerosol-forming material containing an amorphous substance to a carrier, such as paper, to form a structure containing the aerosol-forming material. The aerosol-forming material can be applied to the carrier, for example, by casting, tape casting, spraying or electrospraying. The structure can be stored as a source, for example on a reel. The structure may be drawn, for example, from a source and wound either with or without a mandrel, causing the free ends of the structure to be circumferentially adjacent to each other or butted but not overlapping, thereby creating a tubular or similar shape. tubular with a substantially constant diameter. In this way, the tube can have a seamless connection of the free ends. The aerosol-forming material may face the internal hollow space in a tubular or near-tubular shape. A layer, such as paper, may be wrapped around the outside of the tubular or near-tubular shape and possibly adhered to it to help maintain the tubular or near-tubular shape. This layer may also have free ends that abut or butt but do not overlap. Adhesive, if used, can be applied to the structure using tape casting. Since in this method the free ends of the structure do not overlap, the formed hollow tube has an exceptionally circular, or at least approximately circular, or radially symmetrical cross-section, compared to a hollow tube that contains overlapping free ends of the material. This means that when the device is used, the aerosol-forming material can be heated more uniformly because all areas of the material can be more easily positioned at equal distances from the heating element that heats the aerosol-forming material when the device is used. However, in other embodiments of the invention, the free ends of the combined material may overlap.

In some embodiments of the invention in which the aerosol-forming material is supported on a carrier, the surface of the carrier adjacent to the aerosol-forming material may be porous. For example, in some cases the media contains paper. In some cases, the carrier contains or consists of tobacco material, such as reconstituted tobacco sheet, which may be porous. It has been found that a porous carrier, such as paper, is particularly suitable for some embodiments of the present invention because the porous layer is adjacent to the aerosol-forming material, forming a strong bond with it. The amorphous substance of the aerosol-forming material is formed by drying the gel, and the suspension from which the gel is formed partially impregnates a porous carrier (eg, paper), with the result that when the gel hardens and cross-links, the carrier is partially bound to the gel. This ensures a strong bond between the gel and the carrier (and between the dried gel and the carrier). A porous layer (eg paper) can also be used as a carrier for the flavoring agent. In some cases, the porous layer may comprise paper having a porosity of 0-300 Coresta Units (CU), preferably 5-100 CU or 25-75 CU.

In addition, surface roughness can contribute to the strength of the bond between the aerosol-forming material and the carrier. It has been found that the paper roughness (for the surface adjacent to the carrier) should preferably be in the range of 50-1000 seconds, preferably 50-150 seconds, preferably 100 seconds Beck smoothness (measured in the range of air pressure 50.66-48.00 kPa). A Beck Smoothness Tester is an instrument used to determine the smoothness of a paper surface in which air at a certain pressure is forced between a smooth glass surface and a sample of paper, and the time (in seconds) for a fixed volume of air that leaks between these surfaces is "Beck smoothness"

The consumable material 1, 2 is adapted to be introduced into a heating zone of the device, such as the heating zone 110 of the device 100 shown in FIG. 5. The device has a heating device that heats the aerosol-forming material of the consumable 1, 2 when the consumable is in the heating zone. The aerosol-forming material located in the heating zone 110 is heated by the heating device of the device, which causes at least one component of the aerosol-forming material to evaporate.

The device is configured to apply thermal energy to the consumable material 1, 2 and, in particular, to the aerosol-forming material. In some cases, the device includes a resistive heater that heats up when it is electrically connected to a power source, and thermal energy passes from the resistive heater to the consumable 1, 2.

In some other embodiments of the invention, the device may include a magnetic field generator to create a varying magnetic field to penetrate the heating zone when the consumable material 1, 2 is in the heating zone 110 and the consumable part 1, 2 contains a heating material capable of heating upon penetration into the heating zone. a changing magnetic field to heat the aerosol-forming material. Accordingly, in such embodiments of the invention, the device is configured to generate electromagnetic energy to supply it to the heating material of the consumable material 1, 2 to generate heat in the heating material and transfer this heat from the heating material to the aerosol-forming material. In some cases, the consumable material 1, 2 may contain a heating material that is partially or completely embedded in the aerosol-forming material.

In other embodiments of the invention, the device 100 has a heated element containing a heating material, the heated element is in thermal contact with a heating zone, and the magnetic field generator is configured to generate a varying magnetic field that penetrates the heated element of the device to cause heating of the element. and therefore heating zones. Thus, thermal energy is supplied to any consumable material located in the heating zone.

In either case, the volatile components of the aerosol-forming material are released from the material and from the consumable material 1, 2, for example, when the user draws through the consumable material 1, 2 or the mouthpiece (if any) of the device.

In fig. 5 schematically shows a system 1000 containing the consumable 1 shown in FIG. 1 and 2, and a device 100 for heating an aerosol-forming material in a consumable to vaporize at least one component of the aerosol-forming material. In other embodiments of the invention, the consumable may be replaced by any other consumable, such as consumable 2 shown in FIG. 3 and 4. In this embodiment, the device 100 is a tobacco heating article (also known in the art as a tobacco heating device or a non-combustion heating device).

The device 100 includes a heating zone 110 for receiving the consumable parts 1, 2 and a heating device 112 for heating the aerosol-forming material when the consumables 1, 2 are in the heating zone 110.

The device 100 may have an air inlet (not shown) that fluidly connects the heating zone 110 to the exterior of the device 100. The user may be able to inhale the volatile components of the aerosol-forming material by drawing them out of the heating zone 110. As volatile components are removed from the heating zone 110 and consumables 1, 2, air may be drawn into the heating zone 110 through the air inlet of the device 100.

In this embodiment, the heating zone 110 includes a recess for receiving at least a portion of the consumable material 1, 2. In other embodiments, the heating zone 110 may be different and different from the recess, for example, it may be a shelf, surface or protrusion, and may a mechanical connection to the consumable 1, 2 is required to interact with it or to receive it. In this embodiment, the heating zone 110 is elongated and sized and shaped to accommodate all of the consumables 1, 2. In other embodiments, the heating zone 110 may be sized to accept only a portion of the consumables 1, 2.

In some cases, when using the device, substantially all of the amorphous material is located no more than 4, 3, 2 or 1 mm from the heater (ie, the heated element or resistance heater). In some cases, the amorphous material is located at a distance of about 0.010-2.0 mm from the heater, preferably about 0.02-1.0 mm or 0.1-0.5 mm. These minimum distances may in some cases reflect the thickness of the support that supports the amorphous substance. In some cases, the surface of the amorphous substance may be directly adjacent to the heater.

In some embodiments, fixture 112 includes a power source, a resistive heater capable of heating when electrical current is passed through it, and a controller for controlling the electrical current passing through the resistive heater. The resistance heater is configured to supply thermal energy to the heating zone 110 and, therefore, to the consumables 1, 2 when the consumable is in the heating zone 110. The resistive heater causes thermal energy to be applied to the aerosol-forming material of the consumable 1, 2. In some embodiments, the resistive heater may be included in the heating zone 110, located in the internal channel 20 of the consumable 1, 2 when the consumable is in the heating zone 110. In some other embodiments of the invention, the resistance heater may be located radially outside the consumable material 1, 2 when the consumable material is in the heating zone 110. For example, a resistance heater may at least partially define the heating zone 110. In some embodiments, the device may include a first resistance heater that is located in the internal channel 20 of the consumable 1, 2 when it is in the heating zone 110, and a second resistance heater that is located radially outside the consumable 1, 2 when it is is located in heating zone 110.

In some embodiments of the invention, such as that shown in FIG. 5, the fixture 112 includes a magnetic field generator for generating a varying magnetic field that penetrates the heating zone 110 when the consumable 1, 2 is in the heating zone 110.

As noted above, in some embodiments of the invention, the consumable material contains a heating material for heating the aerosol-forming material. In such cases, the device's magnetic field generator may be configured to generate a varying magnetic field that penetrates the heating material of the consumable 1, 2 when the consumable 1, 2 is in the heating zone 110.

In other embodiments of the invention, such as that shown in FIG. 5, fixture 112 of device 100 includes a heating element 111, and a magnetic field generator is configured to generate a varying magnetic field penetrating the heating element 111. In some cases, the heating element is located radially outside the consumable 1, 2 when it is in the area 110 heating For example, the heating element may at least partially define the heating zone 110. In other embodiments of the invention, such as that shown in FIG. 5, the heating element 111 enters the heating zone 110. The heating element 111 may be configured to introduce consumable material 1, 2 into the inner channel 20 when the device is in use. In some embodiments of the invention, such as that shown in FIG. 5, the heating element 111 enters the inner channel 20 when the consumable material 1, 2 is inserted into the heating zone 110. In other embodiments of the invention, the device may be configured such that the heating element 111 is movable relative to the heating zone 110 to enter the internal channel 20 when the consumable 1, 2 is already in the heating zone 110.

In some embodiments, the outer cross-sectional shape of the heating element 111 of the device matches the shape of the innermost surface 1b, 2b of the hollow tube 1a, 2a of the consumable 1, 2. For example, the inner and outer cross-sectional shapes may be circular or may be non-circular, such as elliptical , polygonal, rectangular, square, triangular, corrugated or star-shaped. In some embodiments of the invention, the heating element 111 of the device and the innermost surface 1b, 2b of the hollow tube 1a, 2a of the consumable material 1, 2 are of such relative sizes that, in use, the innermost surface is adjacent to the heating element 111 to improve the efficiency of transfer of thermal energy from the heating element. element 111 to the innermost surface. The innermost surface may have a close or tight fit with the heating element 111.

In this embodiment, the magnetic field generator includes a power source 113, a coil 114, means 116 for passing a varying electrical current, such as alternating current, through the coil 114, a controller 117, and a user interface 118 for user interaction with the controller 117.

The power supply 113 in this embodiment of the invention is a rechargeable battery. In other embodiments of the invention, the power source 113 may be different, such as a non-rechargeable battery, a capacitor, a hybrid battery-capacitor, or a connection to a power supply.

The coil 114 may have any suitable shape. In some embodiments, coil 114 is a helical coil made of an electrically conductive material, such as copper. In some embodiments of the invention, the coil is flat, i.e. is a two-dimensional spiral made of electrically conductive material such as copper. In some embodiments, a coil 114 surrounds a heating zone 110. In some embodiments, coil 114 extends along a longitudinal axis that is substantially aligned with the longitudinal axis of heating zone 110. Aligned axes can coincide. Alternatively, the aligned axes may be parallel or inclined to each other.

In this embodiment, means 116 for passing varying current through coil 114 is electrically connected between power supply 113 and coil 114. In this embodiment, controller 117 is also electrically connected to power source 113 and coupled to control means 116 for controlling the device 116. More Specifically, in this embodiment, controller 117 is configured to control device 116 to control the supply of power from source 113 to coil 114. In this embodiment, controller 117 includes an integrated circuit (IC), such as a printed circuit board (PCB) IC. In other embodiments of the invention, the controller 117 may be configured differently. In some embodiments, device 100 may have a single electrical or electronic component including means 116 and controller 117. In this case, controller 117 is controlled by user actions through user interface 118. User interface 118 may include a push button, a toggle button, or a dial. , touch screen, or similar components. In other embodiments, the user interface 118 may be remote and connect to the rest of the device 100 wirelessly, such as via Bluetooth.

In this embodiment, the user's actions through the user interface 118 cause the controller 117 to cause the device 116 to pass an alternating electrical current through the coil 114. This causes the coil 114 to generate an alternating magnetic field. The coil 114 and the heating zone 110 of the device 100 are respectively positioned relative to each other so that when the consumable material 1, 2 is located in the heating zone 110, the changing magnetic field generated by the coil 114 penetrates the heating element 111 of the device 100. When the material of the heating element 111 is electrically conductive, this penetration causes one or more eddy currents to appear in the material of the heating element 111. The flow of eddy currents in the material of the heating element 111 in the presence of electrical resistance of the material heats the material by Joule heating. When the material of the heating element 111 is made of a magnetic material, the orientation of the magnetic dipoles in the material of the heating element 111 changes with a change in the applied magnetic field, which causes heat to be generated in the material of the heating element 111.

In some embodiments, the consumable material 1, 2 contains a heating material, and the coil 114 and the heating zone 110 of the device 100 are preferably positioned relative to each other such that when the consumable material 1, 2 is located in the heating zone 110, the changing magnetic field generated by the coil 114 penetrates the heating material of the consumable 1, 2. In some embodiments, the device 100 includes a heating element 111 that contains a heating material, and the consumables 1, 2 also contain a heating material. In some such cases, the coil 114 and the heating zone 110 of the device 100 may be positioned relative to each other such that when the consumable 1, 2 is located in the heating zone 110, the changing magnetic field generated by the coil 114 penetrates the heating material of the consumable 1. 2 and into the heating material of the heating element 111.

The device 100 according to this embodiment of the invention includes a temperature sensor 119 for measuring the temperature in the heating zone 110. The temperature sensor 119 is connected to the controller 117, whereby the controller 117 can monitor the temperature of the heating zone 110. Based on one or more signals received from temperature sensor 119, controller 117 may adjust the characteristics of the variable or alternating electrical current generated by fixture 112 through coil 114 to ensure that the temperature of heating zone 110 remains within a predetermined range. The characteristic may be, for example, amplitude, frequency or duty cycle. Within a predetermined temperature range, during use of the device, the aerosol-forming material in the consumable material located in the heating zone 110 is heated sufficiently to vaporize at least one component of the aerosol-forming material without burning the material. Accordingly, controller 117 and apparatus 100 are generally configured to heat the aerosol-forming material to vaporize at least one component of the aerosol-forming material without burning it.
