In a paramagnetic conductive material, induction heating occurs solely through resistive heating due to eddy currents. Alternatively, the susceptor may comprise a non-conductive ferrimagnetic material, such as a non-conductive ferrimagnetic ceramic. In this case, heat is generated solely through hysteresis losses. The susceptor may comprise a commercially available alloy such as Phytherm 230 (composition including 50 wt% Ni, 10 wt% Cr, and the rest of the Fe (weight % = wt %)) or Phytherm 260 (composition including 50 wt% Ni, 9 wt% Cr, and the rest of the Fe).
[0099] In some embodiments of any of the above embodiments, the susceptor may be a metal foil or film, optionally an aluminum foil or film, or an iron foil or film, or any conductive material that can be sprayed or deposited onto the material that makes up the support.
[0100] An aerosol-forming material is a material that is capable of generating an aerosol when energized, e.g., by heating, irradiating, or in any other manner. The aerosol-forming material may be, for example, in solid, liquid, or semi-solid (e.g., gel) form, and may or may not contain active substances and / or flavorings.
[0101] The aerosol-generating material may include one or more active agents and / or flavorings, one or more aerosol-forming materials, and optionally one or more other functional materials.
[0102] The aerosol-generating material may include a binder, such as a gelling agent, and an aerosol-forming agent. Optionally, a delivery substance and / or a filler may also be present. Optionally, a solvent, such as water, may also be present, in which one or more other components of the aerosol-generating material may or may not be soluble. In some embodiments, the aerosol-generating material is substantially free of plant matter. In particular, in some embodiments, the aerosol-generating material is substantially free of tobacco.
[0103] The aerosol-generating material may include or be in the form of an aerosol-generating film.

[0136] In some cases, the aerosol-forming material may include from about 1 wt%, 5 wt%, 10 wt%, 15 wt%, or 20% to about 60 wt%, 50 wt%, 40 wt%, 30 wt%, or 25 wt% of the gelling agent (DWB). For example, the aerosol-forming material may include from 10 to 40 wt%, 15 to 30 wt%, or 20 to 25 wt% of the gelling agent (DWB).
[0137] For example, the aerosol-forming material may comprise, in total, the gelling agent and the bulking agent in an amount of about 10 wt%, 20 wt%, 25 wt%, 30 wt%, or 35% to about 60 wt%, 55 wt%, 50 wt%, or 45 wt% of the aerosol-forming material.

[0138] By way of example, the aerosol-forming material may comprise a gelling agent in an amount of about 5 wt%, 10 wt%, 15 wt%, 20 wt%, 25 wt%, 30 wt%, or 35% to about 60 wt%, 55 wt%, 50 wt%, or 45 wt% of the aerosol-forming material (i.e., not taking into account the amount of filler). By way of example, the aerosol-forming material may comprise a gelling agent in an amount of about 5-60 wt%, 20-60 wt%, 25-55 wt%, 30-50 wt%, or 35-45 wt% of the aerosol-forming material (i.e., not taking into account the amount of filler).
[0139] In some examples, the alginate is included in the gelling agent in an amount of about 5-40 wt% or 15-40 wt% of the aerosol-forming material, i.e., the aerosol-forming material comprises alginate in an amount of about 5-40 wt% or 15-40 wt% of the aerosol-forming material by dry weight, in some examples, the aerosol-forming material comprises alginate in an amount of about 20-40 wt% or about 15 wt% to 35 wt% of the aerosol-forming material.
[0140] In some examples, the pectin is included in the gelling agent in an amount of about 3-15 wt% of the aerosol-forming material, i.e., the aerosol-forming material comprises pectin in an amount of about 3-15 wt% of the aerosol-forming material by dry weight, hi some examples, the aerosol-forming material comprises pectin in an amount of about 5-10 wt% of the aerosol-forming material.
[0141] In some examples, the guar gum is present in the gelling agent in an amount of about 3-40 wt% of the aerosol-generating material. That is, the aerosol-generating material comprises guar gum in an amount of about 3-40 wt% of the aerosol-generating material by dry weight. In some examples, the aerosol-generating material comprises guar gum in an amount of about 5-10 wt% of the aerosol-generating material. In some examples, the aerosol-generating material comprises guar gum in an amount of about 15-40 wt%, or about 20-40 wt%, or about 15-35 wt% of the aerosol-generating material.
[0142] For example, the alginate is present in an amount of at least about 50 wt% of the gelling agent. For example, the aerosol-forming material includes alginate and pectin, and the ratio of alginate to pectin is 1:1 to 10:1. The ratio of alginate to pectin is usually greater than 1:1. That is, the alginate is present in an amount greater than the amount of pectin. For example, the ratio of alginate to pectin is about 2:1 to 8:1, or about 3:1 to 6:1, or about 4:1.
[0143] The aerosol-generating material may be formed by (a) forming a slurry containing components of the aerosol-generating material or a precursor thereof, (b) forming a layer of the slurry, (c) curing the slurry to form a gel, and (d) drying to form the aerosol-generating material.
[0144] (b) Forming the slurry layer typically involves spraying, casting, or extruding the slurry. For example, the slurry layer may be formed by electrospraying the slurry. For example, the slurry layer may be formed by casting the slurry.
[0145] In some instances, (b), and / or (c), and / or (d) occur at least partially simultaneously (e.g., in an electrospray). In some instances, (b), (c), and (d) occur sequentially.
[0146] In some instances, the slurry may be applied to a support such that a layer is formed on the support. By way of example, the slurry may include a gelling agent, an aerosol-forming material, and an active agent. The slurry may include these components in any of the proportions described herein for the composition of the aerosol-generating material. For example, the slurry may include (on a dry weight basis): a gelling agent and optionally a filler, the amount of gelling agent and filler together being about 10-60 wt% of the slurry; an aerosol-forming material in an amount of about 40-80 wt % of the slurry; Optionally, an active material in an amount of up to about 20 wt. % of the slurry; and may also include
[0147] Hardening the gel (c) may include providing a hardening agent to the slurry, for example the slurry may include sodium, potassium or ammonium alginate as a gel precursor and the addition of a hardening agent to the slurry including a calcium source (such as calcium chloride) to form a calcium alginate gel.
[0148] By way of example, the sclerosing agent may include or consist of calcium acetate, calcium formate, calcium carbonate, calcium bicarbonate, calcium chloride, calcium lactate, or a combination thereof. In some examples, the sclerosing agent may include or consist of calcium formate and / or calcium lactate. In certain examples, the sclerosing agent may include or consist of calcium formate. The inventors have determined that when calcium formate is employed as a sclerosing agent, the aerosol generating material typically exhibits higher tensile strength and resistance to elongation.
[0149] The total amount of hardening agent, such as a calcium source, may be 0.5 to 5 wt % (calculated on a dry weight basis). Preferably, the total amount is about 1 wt %, 2.5 wt %, or 4 wt % to about 4.8 wt % or 4.5 wt %. The inventors have found that if too little hardening agent is added, the components of the aerosol-generating material may not be stable and may drop out of the aerosol-generating material. The inventors have also found that if too much hardening agent is added, the aerosol-generating material may become very sticky and difficult to handle.
[0150] If the aerosol-forming material does not contain tobacco, it may be necessary to apply more stiffening agent. Thus, in some cases, the total amount of stiffening agent may be 0.5 to 12 wt %, such as 5 to 10 wt %, calculated on a dry weight basis. Suitably, the total amount may be from about 5 wt %, 6 wt %, or 7 wt % to about 12 wt % or 10 wt %. In this case, the aerosol-forming material will generally not contain any tobacco.
[0151] As an example, applying the hardener to the slurry includes spraying the hardener onto the slurry, such as onto the top surface of the slurry.
[0152] Alginates are derivatives of alginic acid and are typically high molecular weight polymers (10-600 kDa). Alginic acid is a copolymer of β-D-mannuronic acid (M) and α-L-guluronic acid (G) units (blocks) linked together by (1,4)-glycosidic bonds to form a polysaccharide. Upon addition of calcium cations, alginates crosslink to form a gel. Alginates with a high G monomer content have been found to gel more readily with the addition of a calcium source. Thus, in some cases, the gel precursor may include an alginate in which at least about 40%, 45%, 50%, 55%, 60%, or 70% of the monomer units in the alginic acid copolymer are α-L-glucuronic acid (G) units.
[0153] For example, drying (d) removes from about 50 wt%, 60 wt%, 70 wt%, 80 wt%, or 90 wt% to about 80 wt%, 90 wt%, or 95 wt% (WWB) of the water in the slurry. For example, drying (d) reduces the thickness of the cast material by at least 80%, preferably 85% or 87%. For example, the slurry is cast to a thickness of 2 mm and the resulting dried aerosol-generating material has a thickness of 0.2 mm.
[0154] In some examples, the slurry solvent consists essentially of or consists of water, hi some examples, the slurry comprises about 50 wt%, 60 wt%, 70 wt%, 80 wt%, or 90 wt% solvent (WWB).
[0155] In instances where the solvent comprises water, the dry weight content of the slurry may correspond to the dry weight content of the aerosol-forming material, such that any discussion herein of solid components is expressly disclosed in conjunction with the slurry aspects of the invention.
[0156] The aerosol-forming material may include a flavoring. The aerosol-forming material may include up to about 80 wt%, 70 wt%, 60 wt%, 55 wt%, 50 wt%, or 45 wt% of flavoring. In some cases, the aerosol-forming material may include at least about 0.1 wt%, 1 wt%, 10 wt%, 20 wt%, 30 wt%, 35 wt%, or 40 wt% of flavoring (all calculated on a dry weight basis). For example, the aerosol-forming material may include 1-80 wt%, 10-80 wt%, 20-70 wt%, 30-60 wt%, 35-55 wt%, or 30-45 wt% of flavoring. In some cases, the flavoring includes, consists essentially of, or consists of menthol.
[0157] The aerosol-forming material may include a bulking agent.
[0158] In some embodiments, the aerosol-forming material contains less than 60 wt% filler, such as between 1 wt% and 60 wt%, or between 5 wt% and 50 wt%, or between 5 wt% and 30 wt%, or between 10 wt% and 20 wt%.
[0159] In other embodiments, the aerosol forming material contains less than 20 wt%, preferably less than 10 wt% or less than 5 wt% of a filler. Optionally, the aerosol forming material contains less than 1 wt% of a filler, and optionally no filler.
[0160] In some cases, the aerosol-forming material comprises at least 1 wt% filler (e.g., at least 5 wt%, at least 10 wt%, at least 20 wt%, at least 30 wt%, at least 40 wt%, or at least 50 wt% filler), hi some embodiments, the aerosol-forming material comprises between 5 and 25 wt% filler.
[0161] When present, the filler may include one or more inorganic filler materials, such as calcium carbonate, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, magnesium carbonate, and suitable inorganic adsorbents, such as molecular sieves. The filler may also include one or more organic filler materials, such as wood pulp, cellulose, and cellulose derivatives (e.g., methylcellulose, hydroxypropylcellulose, and carboxymethylcellulose (CMC)). In certain cases, the aerosol-generating material does not include calcium carbonate, such as chalk.
[0162] In certain embodiments that include a filler, the filler is fibrous. For example, the filler may be a fibrous organic filler material such as wood pulp, hemp fiber, cellulose, or a cellulose derivative (e.g., methylcellulose, hydroxypropylcellulose, and carboxymethylcellulose (CMC)).
[0163] Without being bound by theory, it is believed that including a fibrous filler in the aerosol-generating material may increase the tensile strength of the material, which may be particularly advantageous in instances where the aerosol-generating material is provided as a sheet, such as when the sheet defines a rod of aerosolizable material.
[0164] In some embodiments, the aerosol-forming material does not include tobacco fibers, hi certain embodiments, the aerosol-forming material does not include fibrous materials.

In some cases, the aerosol-forming material may include about 1 wt%, 2 wt%, 3 wt%, or 4 wt% to about 20 wt%, 18 wt%, 15 wt%, or 12 wt% nicotine (calculated on a dry weight basis). For example, the aerosol-forming material may include 1-20 wt%, 2-18 wt%, or 3-12 wt% nicotine.
[0168] In some cases, the aerosol-forming material includes an active agent such as a tobacco extract. In some cases, the aerosol-forming material may include 5-60 wt% tobacco extract (calculated on a dry weight basis). In some cases, the aerosol-forming material may include about 5 wt%, 10 wt%, 15 wt%, 20 wt%, or 25 wt% to about 60 wt%, 50 wt%, 45 wt%, 40 wt%, 35 wt%, or 30 wt% tobacco extract (calculated on a dry weight basis). For example, the aerosol-forming material may include 10-50 wt%, 15-40 wt%, or 20-35 wt% tobacco extract. The tobacco extract may contain nicotine in a concentration such that the aerosol-forming material contains from 1 wt%, 1.5 wt%, 2 wt%, or 2.5 wt% to about 6 wt%, 5 wt%, 4.5 wt%, or 4 wt% nicotine (calculated on a dry weight basis).

[0169] In some embodiments, the aerosol-forming material does not include tobacco material and does include nicotine. In some cases, the aerosol-forming material may include from about 1 wt%, 2 wt%, 3 wt%, or 4 wt% to about 20 wt%, 18 wt%, 15 wt%, or 12 wt% nicotine (calculated on a dry weight basis). For example, the aerosol-forming material may include from 1 to 20 wt%, 2 to 18 wt%, or 3 to 12 wt% nicotine.
[0170] In some cases, the total content of actives and / or flavorings may be at least about 0.1 wt%, 1 wt%, 5 wt%, 10 wt%, 20 wt%, 25 wt%, or 30 wt%.

[0173] The tobacco material may be present in the aerosol forming composition in an amount of about 50-95 wt%, or about 60-90 wt%, or about 70-90 wt%, or about 75-85 wt%.
[0174] The tobacco material may be in any form, but is typically shredded (e.g., cut into small pieces). Shredded tobacco material is advantageous because it can be mixed with an aerosol-forming material to provide an aerosol-forming composition having a uniform distribution of tobacco material and aerosol-forming material throughout.
[0175] By way of example, the tobacco material comprises one or more of ground tobacco, tobacco fiber, cut tobacco, extruded tobacco, tobacco stems, reconstituted tobacco, and / or tobacco extract. Surprisingly, the inventors have determined that relatively large amounts of laminar tobacco can be used in the aerosol-generating composition and still provide an acceptable aerosol when heated by a non-combustible aerosol delivery system. Laminar tobacco typically provides superior sensory properties. By way of example, the tobacco material comprises laminar tobacco in an amount of at least about 50 wt%, 60 wt%, 70 wt%, 80 wt%, 85 wt%, 90 wt%, or 95 wt% of the tobacco material. In certain examples, the tobacco material comprises cut tobacco in an amount of at least about 50 wt%, 60 wt%, 70 wt%, 80 wt%, 85 wt%, 90 wt%, or 95 wt% of the tobacco material.
[0176] The tobacco used to produce the tobacco material may be any suitable tobacco, such as a single grade or blend, cut rag or whole leaf, including Virginia, and / or Burley, and / or Oriental.
[0177] In some embodiments, the 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.
[0178] Optionally, the aerosol-forming material may additionally include an emulsifier to emulsify the molten flavoring during preparation. For example, the aerosol-forming material may include about 5 wt% to about 15 wt%, preferably about 10 wt% (calculated on a dry weight basis) of an emulsifier. The emulsifier may include gum acacia.
[0179] In some embodiments, the aerosol-forming material is a hydrogel and contains less than about 20 wt% water, calculated on a wet weight basis. Optionally, the hydrogel contains less than about 15 wt%, 12 wt%, or 10 wt% water, calculated on a wet weight basis. Optionally, the hydrogel contains at least about 1 wt%, 2 wt%, or at least about 5 wt% water (WWB).
[0180] The aerosol-forming material may have any suitable water content, such as between 1 wt% and 15 wt%. Preferably, the water content of the aerosol-forming material is between about 5 wt%, 7 wt%, or 9 wt% and about 15 wt%, 13 wt%, or 11 wt% (WWB), most preferably about 10 wt%. The water content of the aerosol-forming material may be determined, for example, by Karl-Fischer titration or Gas Chromatography with Thermal Conductivity Detector (GC-TCD).
[0181] In some cases, the aerosol-forming material may consist essentially of or consist of a gelling agent, water, an aerosol-forming agent, a flavoring agent, and optionally an active agent.
[0182] In some cases, the aerosol-forming materials may consist essentially of or consist of gelling agent, water, aerosol-forming agent, flavorings, and optionally tobacco materials and / or a nicotine source.
[0183] By way of example, the aerosol-forming material may consist essentially of, or consist of, a gelling agent, an aerosol-forming agent, an active substance, and water.By way of example, the aerosol-forming material may consist essentially of, or consist of, a gelling agent, an aerosol-forming agent, and water.
[0184] As an example, the aerosol-forming material does not include flavorants. In certain instances, the aerosol-forming material does not include active agents. In some embodiments, the aerosol-forming material comprises: 1 to 60 wt % of a gelling agent; 0.1 to 50 wt % of an aerosol generating agent; 0.1 to 80 wt% of fragrance, Including, These weights are calculated on a dry weight basis.
[0185] In some embodiments, the aerosol-forming material comprises 1-80 wt % (dry weight basis) of flavoring. In some embodiments, the aerosol-forming material comprises: 1 to 50 wt % of a gelling agent; 0.1 to 50 wt % of an aerosol generating agent; 30-60wt% fragrance, Including, These weights are calculated on a dry weight basis. In an alternative embodiment, the aerosol-forming material is: 1 to 60 wt % of a gelling agent; 5 to 60 wt % of an aerosol generating agent; 10 to 60 wt % of a gelling agent; Including, These weights are calculated on a dry weight basis. In some embodiments, the aerosol-forming material comprises: 1 to 60 wt % of a gelling agent; 20 to 60 wt % of an aerosol generating agent; 10-60 wt% tobacco extract; Including, These weights are calculated on a dry weight basis.
[0186] In some embodiments, the aerosol-generating material comprises 20-35 wt.% gelling agent, 10-25 wt.% aerosol-forming material, 5-25 wt.% fiber-containing filler, and 35-50 wt.% flavoring and / or active agent.
[0187] In some cases, the aerosol-forming materials may consist essentially of or consist of a gelling agent, an aerosol-forming agent, tobacco extract, water, and optional flavorings. In some cases, the aerosol-forming materials may consist essentially of or consist of glycerol, alginate and / or pectin, tobacco extract, and water.
[0188] In some embodiments, the aerosol-generating material may have a composition (DWB) as follows: a gelling agent (preferably including alginate) in an amount of about 5 wt% to about 40 wt%, or about 10 wt% to 30 wt%, or about 15 wt% to about 25 wt%, a tobacco extract in an amount of about 30 wt% to about 60 wt%, or about 40 wt% to 55 wt%, or about 45 wt% to about 50 wt%, and an aerosol-generating agent (preferably including glycerol) in an amount of about 10 wt% to about 50 wt%, or about 20 wt% to about 40 wt%, or about 25 wt% to about 35 wt% (DWB).
[0189] In one embodiment, the aerosol forming material comprises about 20 wt% alginate gelling agent, about 48 wt% Virginia tobacco extract, and about 32 wt% glycerol (DWB).
[0190] The "thickness" of an aerosol-generating material refers to the shortest distance between a first surface and a second surface. In embodiments in which the aerosol-generating material is in the form of a sheet, the thickness of the aerosol-generating material is the shortest distance between a first planar surface of the sheet and a second surface of the sheet opposite the first planar surface of the sheet.
[0191] In some cases, the layer of aerosol-forming material for forming the aerosol has a thickness of about 0.015 mm to about 1.5 mm, preferably about 0.05 mm to about 1.5 mm or 0.05 mm to about 1.0 mm. Preferably, the thickness may be in the range of about 0.1 mm or 0.15 mm to about 1.0 mm, 0.5 mm, or 0.3 mm.
[0192] In some cases, the aerosol-forming material may have a thickness of from about 0.015 mm to about 1.0 mm. Suitably, the thickness may range from about 0.05 mm, 0.1 mm, or 0.15 mm to about 0.5 mm or 0.3 mm.
[0193] A material having a thickness of 0.2 mm is particularly suitable. The aerosol-generating material may comprise two or more layers, and the thicknesses given herein refer to the combined thicknesses of these layers.
[0194] It has been found that if the aerosol-generating material is too thick, it will heat less efficiently, which will have a negative impact on power consumption during use. Conversely, if the aerosol-generating material is too thin, it will be difficult to manufacture and handle. If the material is too thin, it will be more difficult to mold and may even be fragile, compromising aerosol formation during use.
[0195] The thicknesses specified herein are the average thickness of the material. In some cases, the thickness of the aerosol-generating material may vary by no more than 25%, 20%, 15%, 10%, 5%, or 1%.
[0196] In some examples, the aerosol-generating material in sheet form may have a tensile strength of about 200 N / m to about 900 N / m. In some examples, such as when the aerosol-generating material does not include a filler, the aerosol-generating material may have a tensile strength of 200 N / m to 400 N / m, or 200 N / m to 300 N / m, or about 250 N / m.
[0197] Such tensile strengths may be particularly suitable for embodiments in which the aerosol-generating material is formed into a sheet, which is then chopped and incorporated into an aerosol product. In some instances, such as where the aerosol-generating material includes a filler, the aerosol-generating material may have a tensile strength of around 600N / m to 900N / m, or 700N / m to 900N / m, or 800N / m. Such tensile strengths may be particularly suitable for embodiments in which the aerosol-generating material is included in an aerosol product / assembly as a rolled sheet, preferably in the form of a tube.
[0198] In some examples, the aerosol-generating material in sheet form may have a tensile strength of around 200 N / m to around 2600 N / m. In some examples, the aerosol-generating material may have a tensile strength of around 600 N / m to around 2000 N / m, or 700 N / m to 1500 N / m, or around 1000 N / m. Such tensile strengths may be particularly suitable for embodiments in which the aerosol-generating material is formed and incorporated into an aerosol-generating consumable as a sheet.
[0199] The aerosol-generating material is 30 g / m 2 ~120g / m 2 In some cases, the mass per unit area of the sheet may be 80 to 120 g / m 2 , or about 70 to 110 g / m 2 , or, in particular, about 90 to 110 g / m 2 , or preferably about 100 g / m 2 (which has a density similar to that of cut rag tobacco so that mixtures of these materials do not easily separate). Optionally, the mass per unit area of the sheet is about 30 to 70 g / m 2 , 40~60g / m 2 , or 25 to 60 g / m 2 and may be adapted to be used to wrap an aerosolizable material such as tobacco.
[0200] All weight percentages (expressed as wt%) referred to herein are calculated on a dry weight basis unless expressly stated otherwise. All weight ratios are also calculated on a dry weight basis. Weights quoted on a dry weight basis represent the totality of the extract, or slurry, or material, excluding water, and may include ingredients that are themselves liquids at room temperature and pressure, such as glycerol. In contrast, weight percentages quoted on a wet weight basis represent all ingredients, including water.
[0201] The aerosol-generating material may include a colorant. The addition of a colorant can change the visual appearance of the aerosol-generating material. The presence of a colorant in the aerosol-generating material can enhance the visual appearance of the aerosol-generating material. By adding a colorant to the aerosol-generating material, the aerosol-generating material can be color-matched to other components of the article that contains the aerosol-generating material.
[0202] A variety of colorants may be used depending on the desired color of the aerosol-generating material. The color of the aerosol-generating material may be, for example, white, green, red, purple, blue, brown, or black. Other colors are contemplated. Natural or synthetic colorants may be used, such as natural or synthetic dyes, food grade colors, and pharmaceutical grade colors. In a particular embodiment, the colorant is caramel, which may give the aerosol-generating material a brown appearance. In such an embodiment, the color of the aerosol-generating material may be similar to the color of other components of the aerosol-generating material, such as the tobacco material.
[0203] The colorant may be incorporated into the aerosol-forming material during formation (e.g., during formation of a slurry containing the materials that make up the aerosol-forming material) or may be applied after formation of the aerosol-forming material (e.g., by spraying onto the aerosol-forming material).
[0204] In some embodiments of any of the above embodiments, talc powder, calcium carbonate powder, or other powder is applied to an exposed surface of at least one discrete portion of the aerosol-generating material, which may reduce the level of tackiness or adhesiveness of the aerosol-generating material.
[0205] In the following discussion of the accompanying drawings, when an identical element is present in more than one embodiment, the same reference number is used for that element throughout, and when similar elements are present, like reference numbers (the same number plus a multiple of 100) are used.
[0206] 1, the aerosol delivery device 2 comprises a casing 4 within which is disposed a heating assembly 6. The heating assembly 6 is comprised of a heating chamber 8 and an aerosol generator 10. The aerosol generator 10 may be an electrical resistance heater or a magnetic field generator for use with a susceptor.
[0207] The heating chamber 8 defines an opening or mouth 12 at a first end of the heating chamber 8. At an opposite end of the heating chamber 8 is an opening 14. The opening 14 is in fluid communication with a mouthpiece 16 via a conduit 18.
[0208] Also disposed within the casing 4 is a controller 20 in electronic communication with the aerosol generator 10 to control its function. The controller 20 may include a memory (not shown) in which one or more tables relating to the operation of the heater 10 may be stored. The aerosol generator 10 and the controller 20 are powered by a power source 22. The power source 22 is a rechargeable battery. In other embodiments, the power source may be another suitable power source.
[0209] The aerosol generating device 2 is suitable for use with a consumable 24. The consumable 24 and the heating chamber 8 are sized and configured such that at least a portion of the consumable 24 can be reversibly inserted into the heating chamber 8. The consumable 24 comprises one or more discrete portions of aerosol-generating material. When the consumable 24 is inserted into the heating chamber 8 to the extent required by the design of the heating device 2 and the consumable 24, one or more of the discrete portions of aerosol-generating material can be heated by the aerosol generator 10. Although the consumable 24 and the heating chamber 8 are shown as rectangular in FIG. 1, they may be other shapes and configurations.
[0210] 2 and 3, the consumable 24 comprises a support 26, a cover 28, and a plurality of discrete portions of aerosol-generating material in the form of an aerosol-generating film 30. As shown in FIG.
[0211] The support 26 is a laminate and includes a first layer 32 and a second layer 36. The first layer 32 is constructed of aluminum foil, and all or a portion of the first layer may act as a susceptor when exposed to an alternating magnetic field. The second layer 36 of the support 26 is constructed of cardboard.
[0212] The first layer 32 is substantially flat or planar and has first and second major surfaces that define the two largest surfaces of the layer 32. The first major surface does not face the second layer 36 of the support 26 and serves as the support surface 34. The second layer 36 is secured to the second major surface of the first layer 32 using an adhesive (not shown).
[0213] 2 and 3, the support surface 34 is configured to be entirely covered by the cover 28, and therefore the covered portion of the support surface 34 is the entire support surface 34. In other examples not shown, a portion of the support surface that is less than the entire support surface constitutes the covered portion of the support surface.
[0214] The cover 28 covers the support surface 34 and has a cover surface 38 facing the support surface 34. The cover 28 is a sheet material and has a three-dimensional structure due to embossing. The embossing introduces two parallel linear ridges 28A, one groove 28B, and two parallel grooves 28C into the cover 28. The shape of the ridges and grooves 28A, 28B is trapezoidal. In other examples not shown, the cover may be configured with more ridges and grooves 28A, 28B, and the shape of the ridges and grooves may be different shapes, such as, but not limited to, sinusoidal, rectangular, or triangular.
[0215] When cover 28 covers support surface 34, at least a portion of cover surface 38 of each valley 28B or partial valley 28C is in contact with (i.e., touching or adjacent to) support surface 34. The zone where cover surface 38 and support surface 34 are in contact is a contact zone 40. In each contact zone 40, cover surface 38 is secured to support surface 34 by adhesive 42.
[0216] When the cover 28 covers the support surface 34, the cover surface 38 at the peaks 28A, the portions of the cover surface 38 at the valleys 28B that are not in contact with the support surface 34, and the portions of the support surface 34 that are not in contact with the cover 28 collectively define a pair of passages 44. The passages 44 are separated from one another by the contact zones 40, and because the peaks 28A are parallel and linear, the passages 44 are also parallel and linear. Each passage 44 has a first end 44A and a second end 44B. The first and second ends 44A, 44B of the passages 44 are defined by the edges or perimeters of the cover 28 and the support 26, respectively.
[0217] Spaced along each of the passages 44 are a plurality of discrete portions of the aerosol-generating film 30. The portions of the aerosol-generating film 30 are disposed at portion locations 46 on the support surface 34. The configuration of the valleys and peaks 28B, 28A of the cover 28 is such that the discrete portions of the aerosol-generating film 30 do not contact the cover surface 38.
[0218] When the consumable 24 is used in the aerosol generation device 2 with the aerosol generator 10 in the form of a magnetic field generator, the aerosol generator 10 heats the foil of the first layer 32 at one or more partial positions 46. This heats the aerosol-generating membrane 30 at the heated partial positions 46 and generates an aerosol. When a user of the device 2 utilizes the mouthpiece 16, air is drawn along at least one of the passages 44 from one end 44A or 44B to the other end 44B or 44A, drawing the aerosol from the heated aerosol-generating membrane 30 into the mouthpiece 16.
[0219] 4, this shows a consumable 124. The consumable 124 has a support 26 of the same configuration and layout as the support 26 of the consumable 24 of FIGS.
[0220] The cover 128 covers a support surface (not shown in FIG. 4) and has a cover surface (not shown in FIG. 4) facing the support surface side. The cover 128 is a sheet material and has a three-dimensional configuration due to folding. The folding of the cover 128 forms two parallel linear ridges 128A, one groove 128B, and two parallel grooves 128C. The shapes of the ridges and grooves 128A, 128B are trapezoidal.
[0221] When the cover 128 covers the support surface, at least a portion of the cover surface of each valley 128B or partial valley 128C contacts (i.e., touches or is adjacent to) the support surface. The zone where the cover surface and the support surface are in contact is a contact zone (not shown in FIG. 4). At each contact zone, the cover surface is secured to the support surface by melting at least a portion of the cover 128 and fusing the melted portion of the cover 128 with the cover surface before solidifying. In other examples of consumables of the present disclosure not shown, the support and the cover are joined at the contact zone by one or more mechanical fastening means, such as staples (staples are short, thin wires that are pushed through the cover 128 and support 26 and then bent flat).
[0222] When the cover 128 covers the support surface, the cover surface of the peaks 128A, the parts of the cover surface of the valleys 128B that are not in contact with the support surface, and the parts of the support surface that are not in contact with the cover 128 together define a pair of passages (not shown in FIG. 4). The passages are separated from each other by contact zones, and because the peaks 128A are parallel and linear, the passages are also parallel and linear. The ends of the peaks 128A are closed by end plates 148A, 148B, and the passage ends 144A, 144B are formed by openings through the cover 128 adjacent the end plates 148A, 148B. Such an arrangement allows for different management of the airflow through the consumable 124 and / or the aerosol generation device 2.
[0223] Spaced along each of the passages are a plurality of discrete portions of the aerosol-generating film 30. Portions of these aerosol-generating film 30 are disposed at partial locations (not shown in FIG. 4) on the support surface. The configuration of the valleys and peaks 128B, 128A of the cover 128 is such that the discrete portions of the aerosol-generating film 30 do not contact the cover surface.
[0224] 5, 6 and 7, FIG. 5 shows a partially formed consumable 224 including a support 226, a cover 228, and a plurality of aerosol-generating membrane discrete portions 230, 252. As shown in FIG.
[0225] The support 226 is a laminate and includes a first layer 232 and a second layer 236. The first layer 232 is constructed of aluminum foil, and all or a portion of the first layer may act as a susceptor when exposed to an alternating magnetic field. The second layer 236 of the support 226 is constructed of cardboard.
[0226] The first layer 232 is substantially flat or planar and has first and second major surfaces that define the two largest surfaces of the layer 232. The first major surface does not face the second layer 236 of the support 226 and serves as a support surface 234. The second layer 236 is secured to the second major surface of the first layer 232 using an adhesive (not shown).
[0227] The support surface 234 comprises a covering portion 234A, a second portion 234B, and a hinge portion 234C present between the covering portion and the second portion 234A, 234B. The covering portion and the second portion 234A, 234B are joined to the hinge portion 234C by first and second fold lines 250A, 250B.
[0228] The covering portion 234 A of the support surface 234 is configured to be entirely covered by the cover 228 .
[0229] The cover 228 covers the covering portion 234A of the support surface 234 and has a first cover surface 238 facing the covering portion 234A side of the support surface 234. The cover 228 also has a second cover surface 254 facing in the opposite direction to the first cover surface 238. The cover 228 is a sheet material and has a three-dimensional configuration formed by molding. Two parallel linear ridges 228A, one groove 228B, and two partial grooves 228C are formed by molding. The shapes of the ridges and grooves 228A, 228B are trapezoidal.
[0230] When the cover 228 covers the covering portion 234A of the support surface, at least a portion of the covering surface 238 of each valley 228B or partial valley 228C is in contact with (i.e., touching or adjacent to) the covering portion 234A of the support surface. The zone of contact between the first covering surface 238 and the covering portion 234A of the support surface is a contact zone 240. In each contact zone 240, the first covering surface 238 is fixed to the covering portion 234A of the support surface by the adhesive 42.
[0231] When the cover 228 covers the covering portion 234A of the support surface, the first covering surface 238 of the peaks 228A, the portions of the first covering surface 238 of the valleys 228B that are not in contact with the first portion 234A of the support surface, and the portions of the covering portion 234A of the support surface that are not in contact with the cover 228 together define a pair of passages 244. The passages 244 are separated from each other by the contact zones 240, and because the peaks 228A are parallel and linear, the passages 244 are also parallel and linear. Each passage 244 has a first end 244A and a second end 244B. The first and second ends 244A, 244B of the passages 244 are defined by the edges or perimeters of the cover 228 and the support portion 226, respectively.
[0232] Spaced along each of the passages 244 are a plurality of discrete aerosol-generating film portions 230. The portions of the aerosol-generating film 230 are disposed at portion locations 246 on the first portion 234A of the support surface. The configuration of the valleys and peaks 228B, 228A of the cover 228 is such that the discrete aerosol-generating film portions 230 do not contact the first cover surface 238.
[0233] The second portion 234B of the support surface 234 is substantially flat and supports a plurality of aerosol-generating film segments 252 disposed in a second position 260. A barb 256 extends from an edge 258 of the support portion 236.
[0234] The support portion 226 is folded approximately 90° about each of the folds 250A, 250B to provide the necessary configuration for use of the consumable 224 (as shown in FIGS. 6 and 7), such that the second portion 234B of the support surface 234 covers the cover 228 and contacts or rests adjacent to a portion of the second cover surface 254 that forms part of the peak 228A of the cover 228.
[0235] The second cover surface 254 of the valley portion 228B, the portion of the second cover surface 228 of the peak portion 228A that is not in contact with or adjacent to the second portion 234B of the support surface 234, and a portion of the second portion 234B of the support surface 234 together define a passageway 245. The passageway 245 is linear and parallel to the passageway 244 and has first and second ends 245A, 245B.
[0236] To hold the support portion 226 in the folded configuration, the barb members 256 are secured to the second cover surface 254 using adhesive 242 .
[0237] The positioning locations 260 and the aerosol-generating film discrete portions 252 are disposed on the second portion 234 B of the support surface 234 so as not to contact the second cover surface 254 within the passageway 245 .
[0238] When the consumable 224 is used in the aerosol generating device 2 with the aerosol generator 10 in the form of a magnetic field generator, the aerosol generator 10 heats the foil of the first layer 232 at one or more of the part positions 246, 260. This heats the aerosol-generating membrane 230, 252 at the heated part positions 246, 260 and generates an aerosol. When a user of the device 2 utilizes the mouthpiece 16, air is drawn along at least one of the passages 44, 45 from one end 44A, 45A or 44B, 45B to the other end 44B, 44B or 44A, 45A, drawing the aerosol from the heated aerosol-generating material 230, 252 into the mouthpiece 16.
[0239] In an alternative embodiment of the consumable 224, as shown in FIG. 8, the wrap 262 extends around the longitudinal extent of the support 226 in the consumable 324 to hold the support and cover 228 in the configuration shown in FIG. 8. In this embodiment, the hooks 256 and adhesive 242 of the support 226 used in the embodiment shown in FIGS. 5-7 may all be omitted. As an advantage of this embodiment, the wrap 262 may be a suitable heat resistant film, which can protect the support 226, cover 228, and aerosol-generating films 230, 252 from physical damage and moisture. In some examples, the wrap 262 closes the ends 244A, 244B, 245A, 245B of the passages 244, 245 when it is initially wrapped around the folded support 226 and cover 228. To use consumable 324, it is prepared for use by opening ends 244A, 244B, 245A, 245B of passages 244, 245 by piercing or removing a portion of wrap 262. Consumable 324 is then used in the same manner as described in connection with consumable 224 above.
[0240] 9, this shows an alternative support 426 and cover 428 during manufacture of the consumable 424. The support 426 is the same as that used for the consumable 224 described above, except that the aerosol-generating film discretizations 252 are arranged in a grid pattern on the second portion 234B of the support surface 234.
[0241] The cover 428 is formed from a blow-molded plastic sheet and in combination with the first portion 234A of the support surface defines three passages 444. Each passage 444 includes three chambers 464 (not all of the chambers 464 are numbered for clarity). The centerlines of each passage 444 are linear and parallel to one another. In each passage 444, the chambers 446 are joined in series by two conduits 466 (not all of the chambers 464 are numbered for clarity). The chambers 464 are larger than the conduits 466 in at least one direction perpendicular to the centerline of the passages 444.
