Description

Consumable for a non-combustible aerosol provision device comprising two different aerosol generating materials

Technical Field

The present invention relates to a consumable for use with a non-combustible aerosol provision device (consumable), the consumable comprising an aerosol-generating material (aerosol-generating material) containing an amorphous solid.

Background

Smoking consumables such as cigarettes, cigars, and the like burn tobacco during use to produce tobacco smoke. Alternatives to these types of consumables release an inhalable aerosol or vapor by heating, but not burning, a substrate material to release a compound. These may be referred to as non-combustible smoking consumables or aerosol generating components.

One example of such a product is a heating device that releases a compound by heating, but not burning, a solid aerosol generating material. In some cases, the solid aerosol generating material may comprise a tobacco material. Heating volatilizes at least one component of the material, typically forming an inhalable aerosol. These products may be referred to as heated non-combustion devices, tobacco heating devices, or tobacco heating products. Various arrangements for volatilising at least one component of a solid aerosol generating material are known.

Another example is a mixing device. These include liquid sources (which may or may not contain nicotine) that are vaporized by heating to produce an inhalable vapor or aerosol. The device additionally comprises a solid aerosol generating material (which may or may not comprise tobacco material) and components of such material are entrained in the inhalable vapour or aerosol to generate the inhalation medium.

In some such embodiments, the amorphous solids of the first and second aerosol generating materials comprise the same active substance. In some such embodiments, the active is present in varying amounts. As used herein, "amount" may mean that the amorphous solid contains 0% active, in other words, the amorphous solid of the first or second aerosol generating material is free of active present in the amorphous solid of the other aerosol generating material.

In some embodiments, the amorphous solids of both the first and second aerosol generating materials comprise an active substance. In some such embodiments, the amorphous solids of the first and second aerosol generating materials comprise the same active material, wherein the amorphous solids of the first aerosol generating material comprise an amount of active material that is greater than the amount of active material present in the amorphous solids of the second aerosol generating material.

In some such embodiments, the amorphous solid of the first aerosol-generating material comprises the same active material as is present in the amorphous solid of the second aerosol-generating material. In some such embodiments, the amorphous solid of the first aerosol-generating material comprises an active material that is different from the active material present in the amorphous solid of the second aerosol-generating material.

In such an embodiment, the two aerosol generating materials may comprise substantially the same composition, except that the amount of active present in each of the two aerosol generating materials is different. In a non-limiting example, a consumable according to the present invention comprises:

In some cases, the amorphous solid of at least one of the above-described aerosol-generating materials comprises more than one of a flavorant, an active, and/or an acid.

In such embodiments, the two aerosol generating materials (e.g. the first and second aerosol generating materials) may comprise substantially the same ingredients, except that the amorphous solid of the first aerosol generating material comprises a flavourant that is different from the flavourant present in the amorphous solid of the second aerosol generating material. In a non-limiting example, the amorphous solids of the two aerosol generating materials comprise an active material, an acid, and a flavorant, wherein the flavorant in the amorphous solids of the first aerosol generating material is different from the flavorant in the amorphous solids of the second aerosol generating material. In some embodiments, a consumable of the present invention may comprise more than two aerosol generating materials, wherein the amorphous solid of each aerosol generating material comprises a flavorant that is different from the flavorant present in at least one other amorphous solid of another aerosol generating material in a consumable of the present invention.

It is also envisaged that the aerosol generating materials in the consumable of the present invention differ from each other in the amount of flavouring agent or acid. In some such embodiments, the flavoring agent of the amorphous solid of the first aerosol generating material is present in an amount that is different from the amount of flavoring agent in the amorphous solid of the second aerosol generating material. For example, the amount of flavouring agent present in the amorphous solid of the first aerosol generating material is greater than the amount of flavouring agent present in the second aerosol generating material. In some such embodiments, the acid of the amorphous solid of the first aerosol-generating material is present in an amount that is different from the amount of acid in the amorphous solid of the second aerosol-generating material.

Amorphous solid composition (composition)

The following discussion of the composition of the amorphous solid applies independently to the amorphous solid of each aerosol generating material present in the consumable of the present invention.

In some cases, the amorphous solid may have a thickness of about 0.015mm to about 1.0 mm. Suitably, the thickness may be in the range of about 0.05mm, 0.1mm or 0.15mm to about 0.5mm, 0.3mm or 0.2 mm. The inventors have found that amorphous solids having a thickness of 0.2mm are particularly suitable. In some embodiments, the amorphous solid may have a thickness of about 0.1-0.2 mm. The amorphous solid may comprise more than one layer, and the thickness described herein refers to the total thickness of those layers.

The inventors have determined that if the amorphous solid is too thick, the heating efficiency suffers. This adversely affects the power consumption in use. Conversely, if the amorphous solid is too thin, it is difficult to manufacture and handle; very thin materials are more difficult to cast and may be brittle, compromising aerosol formation in use.

The inventors have determined that the amorphous solid thickness specified herein optimizes material properties in view of these competing considerations. The thickness specified herein is the average thickness of the material. In some cases, the amorphous solid thickness may vary by no more than 25%, 20%, 15%, 10%, 5%, or 1%.

In some cases, the amorphous solid may be heated to produce a primary aerosol. In some cases, the amorphous solid may be heated to produce more than one (such as two or three) aerosols.

When the amorphous solid is heated more than once, thicker amorphous solids may be used. For example, in some embodiments, the thickness may be 0.2-0.5mm.

In some cases, the amorphous solid may comprise 1 to 60wt% gelling agent, where these weights are calculated on a dry weight basis.

In some embodiments, the gelling agent comprises a hydrocolloid. In some embodiments, the gelling agent comprises one or more compounds selected from the group comprising: alginates, pectins, starches (and derivatives), celluloses (and derivatives such as methylcellulose, hydroxypropylcellulose, and carboxymethylcellulose (CMC)), gums (gum, gummy, chewing gum), silica or silicone compounds, clays, polyvinyl alcohols, and combinations thereof. For example, in some embodiments, the gelling agent comprises one or more of alginate, pectin, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose, pullulan, xanthan gum, guar gum, carrageenan, agarose, gum arabic, fumed silica, PDMS, sodium silicate, kaolin, and polyvinyl alcohol. In some cases, the gelling agent comprises alginate and/or pectin, and may be combined with a hardening agent (such as a calcium source) during formation of the amorphous solid. In some cases, the amorphous solid may comprise calcium-crosslinked alginate and/or calcium-crosslinked pectin.

In some cases, the gelling agent may be combined with a hardening agent (such as a calcium source) during the formation of the amorphous solid.

In an example, the hardening agent comprises or consists of calcium acetate, calcium formate, calcium carbonate, calcium bicarbonate, calcium chloride, calcium lactate, or a combination thereof. In some examples, the hardener comprises or consists of calcium formate and/or calcium lactate. In a specific example, the hardening agent comprises or consists of calcium formate. The inventors have determined that typically the use of calcium formate as a hardener results in an amorphous solid with greater tensile strength and greater resistance to elongation.

The total amount of hardening agent (such as a calcium source) may be 0.5-5wt% (dry basis). Suitably, the total amount may be about 1wt%, 2.5wt% or 4wt% to about 4.8wt% or 4.5wt%. The inventors have found that adding too little hardener may result in amorphous solids that do not stabilize the amorphous solid components and cause these components to fall out of the amorphous solid. The inventors found that adding too much hardener produced amorphous solids that were very sticky and thus had poor handleability.

When the amorphous solid does not contain tobacco, it may be desirable to apply a higher amount of hardening agent. In some cases, the total amount of hardener may thus be 0.5-12wt%, such as 5-10wt%, calculated on a dry weight basis. Suitably, the total amount may be from about 5wt%, 6wt% or 7wt% to about 12wt% or 10wt%. In this case, the amorphous solid does not generally contain any tobacco.

In some embodiments, the gelling agent comprises alginate, and the alginate is present in the amorphous solid in an amount of 10-30wt% (based on dry weight) of the amorphous solid. In some embodiments, the alginate is the only gelling agent present in the amorphous solid. In other embodiments, the gelling agent comprises alginate and at least one additional gelling agent such as pectin.

In some embodiments, the gelling agent comprises a mixture of alginate and carboxymethylcellulose (CMC). Suitably, the gelling agent comprises a greater amount of CMC than alginate; for example, in some cases, the ratio of CMC to alginate is about 5:1, about 3:1, about 2:1, or about 1.5; for example in the range of 5:1-1.5.

In some embodiments, the amorphous solid may comprise a gelling agent comprising carrageenan.

In some embodiments, the gelling agent may comprise one or more compounds selected from the group consisting of cellulosic gelling agents, non-cellulosic gelling agents, guar gum, gum arabic, and mixtures thereof.

In some embodiments, the cellulose gelling agent is selected from the group consisting of: hydroxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose (CMC), hydroxypropyl methyl cellulose (HPMC), methyl cellulose, ethyl cellulose, cellulose Acetate (CA), cellulose Acetate Butyrate (CAB), cellulose Acetate Propionate (CAP), and combinations thereof.

In some embodiments, the gelling agent comprises (or is) one or more of hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose (HPMC), carboxymethylcellulose, guar gum, or gum arabic.

In some embodiments, the gelling agent comprises (or is) one or more non-cellulosic gelling agents, including but not limited to agar, xanthan gum, gum arabic, guar gum, locust bean gum, pectin, carrageenan, starch, alginate, and combinations thereof. In a preferred embodiment, the non-cellulose based gelling agent is alginate or agar.

Suitably, the amorphous solid may comprise from about 5wt%, 10wt%, 15wt% or 20wt% to about 80wt%, 70wt%, 60wt%, 55wt%, 50wt%, 45wt%, 40wt% or 35wt% aerosol-forming material (all calculated on a dry weight basis). The aerosol-forming material may act as a plasticiser. For example, the amorphous solid may comprise 10 to 60wt%, 15 to 50wt% or 20 to 40wt% of the aerosol-forming material. In some cases, the aerosol-forming material comprises one or more compounds selected from erythritol, propylene glycol, glycerol, triacetin, sorbitol, and xylitol. In some cases, the aerosol-forming material comprises, consists essentially of, or consists of glycerin. The inventors have determined that if the content of aerosol-forming material is too high, the amorphous solid may absorb water, resulting in a material that does not give rise to a suitable consumer experience in use. The inventors have determined that if the aerosol-forming material content is too low, the amorphous solid may be brittle and easily crumble.

In some embodiments, the aerosol former comprises one or more polyols, such as propylene glycol, triethylene glycol, 1,3-butanediol, and glycerin; esters of polyhydric alcohols, such as glycerol monoacetate, diacetate, or triacetate; and/or aliphatic esters of mono-, di-or polycarboxylic acids, such as dimethyl dodecanedioate and dimethyl tetradecanedioate.

In embodiments where the amorphous solid comprises a flavoring agent, suitably, the amorphous solid comprises up to about 60, 50, 40, 30, 20, 10 or 5wt% of the flavoring agent. In some cases, the amorphous solid can comprise at least about 0.5wt%, 1wt%, 2wt%, 5wt%, 10wt%, 20wt%, or 30wt% flavoring (all calculated on a dry weight basis). For example, the amorphous solid may comprise 0.1 to 60wt%, 1 to 60wt%, 5 to 60wt%, 10 to 60wt%, 20 to 50wt%, or 30 to 40wt% of the flavoring agent. In some cases, the flavoring agent (if present) comprises, consists essentially of, or consists of menthol. In some cases, the amorphous solid does not contain a flavoring agent.

In embodiments in which the aerosol-generating material of the invention comprises an active substance, in some cases the amorphous solid comprises a tobacco material and/or nicotine. For example, the amorphous solid may comprise powdered tobacco and/or nicotine and/or a tobacco extract. In some cases, the amorphous solid may comprise from about 1wt%, 5wt%, 10wt%, 15wt%, 20wt%, or 25wt% to about 70wt%, 50wt%, 45wt%, or 40wt% (by dry weight) of the active. In some cases, the amorphous solid can comprise about 1wt%, 5wt%, 10wt%, 15wt%, 20wt%, or 25wt% to about 70wt%, 60wt%, 50wt%, 45wt%, or 40wt% (by dry weight) of tobacco material and/or nicotine.

In embodiments where the aerosol-generating material comprises an active material, such as a tobacco extract, in some cases the amorphous solid may comprise 5-60wt% (on a dry weight basis) of the tobacco extract. In some cases, the amorphous solid can comprise about 5wt%, 10wt%, 15wt%, 20wt%, or 25wt% to about 55wt%, 50wt%, 45wt%, or 40wt% (by dry weight) of the tobacco extract. For example, the amorphous solid may comprise 5-60wt%, 10-55wt%, or 25-55wt% of the tobacco extract. The tobacco extract may comprise nicotine at a concentration such that the amorphous solid comprises from 1wt%, 1.5wt%, 2wt% or 2.5wt% to about 6wt%, 5wt%, 4.5wt% or 4wt% (on a dry weight basis) nicotine. In some cases, nicotine may not be present in the amorphous solid except for nicotine produced by the tobacco extract.

In some embodiments, the amorphous solid does not comprise tobacco material but comprises nicotine. In some such cases, the amorphous solid can comprise from about 1wt%, 2wt%, 3wt%, or 4wt% to about 20wt%, 15wt%, 10wt%, or 5wt% (by dry weight) nicotine. For example, the amorphous solid may comprise 1-20wt% or 2-5wt% nicotine.

In embodiments where the amorphous solid comprises an acid, the amorphous solid may comprise from 1 to 20wt%, 5 to 15wt%, or 8 to 12wt% (on a dry basis) of the acid, for example from 1wt%, 2wt%, 3wt%, or 4wt% to about 20wt%, 15wt%, 10wt%, or 5wt% (on a dry basis) of the acid.

Without wishing to be bound by theory, it is believed that the inclusion of an acid in the amorphous solid protonates the nicotine and produces an aerosol which some users of smoking devices find more satisfactory.

The aerosol generating material or the amorphous solid may comprise an acid.

In embodiments where the aerosol-generating material or amorphous solid comprises nicotine, the inclusion of an acid is particularly preferred. In such embodiments, the presence of the acid may stabilize the dissolved species in the slurry forming the aerosol generating material or the amorphous solid. The presence of the acid may reduce or substantially prevent evaporation of nicotine during drying of the slurry, thereby reducing loss of nicotine during manufacture.

In some such embodiments, the acid may comprise an acidic functional group (acidic functional group) having a pK measured at 25 ℃ in the range of 2 to 6, such as in the range of 3 to 6 or in the range of 4 to 5 _a The value is obtained.

In some such embodiments, the acid may have a boiling point in the range of 70 ℃ to 450 ℃, for example in the range of 100 ℃ to 320 ℃.

In some such embodiments, the amorphous solid comprises 1-20wt% of the acid, wherein the acid has a functional group having a pK measured at 25 ℃ in the range of 2 to 6 _a And wherein the acid has a boiling point in the range of 70 ℃ to 350 ℃.

In some such embodiments, the acid may be an organic acid.

In some of these embodiments, the acid may be at least one of a monoprotic acid, a diprotic acid, and a triprotic acid.

In some such embodiments, the acid may comprise at least one carboxyl functional group.

In some such embodiments, the acid may be at least one of an alpha-hydroxy acid, a carboxylic acid, a dicarboxylic acid, a tricarboxylic acid, and a keto acid.

In some such embodiments, the acid may be an alpha-keto acid.

In some such embodiments, the acid may be at least one of succinic acid, lactic acid, benzoic acid, citric acid, tartaric acid, fumaric acid, levulinic acid, acetic acid, malic acid, formic acid, sorbic acid, benzoic acid, propionic acid, and pyruvic acid.

Suitably, the acid is lactic acid. In other embodiments, the acid is benzoic acid.

In other embodiments, the acid may be an inorganic acid. In some of these embodiments, the acid may be a mineral acid. In some such embodiments, the acid may be at least one of sulfuric acid, hydrochloric acid, boric acid, and phosphoric acid.

In some embodiments, the acid is levulinic acid.

In embodiments where the amorphous solid comprises an acid, the amorphous solid may comprise from 1wt%, 2wt%, 3wt%, or 4wt% to about 20wt%, 15wt%, 10wt%, or 5wt% (by dry weight) of the organic acid.

In embodiments where the amorphous solid comprises an acid, the amorphous solid may comprise from 1wt%, 2wt%, 3wt%, or 4wt% to about 20wt%, 15wt%, 10wt%, or 5wt% (by dry weight) of the acid comprising a carboxyl functional group.

In embodiments where the amorphous solid comprises an acid, the amorphous solid may comprise from 1wt%, 2wt%, 3wt%, or 4wt% to about 20wt%, 15wt%, 10wt%, or 5wt% (by dry weight) of an acid comprising an acidic functional group having a pK of between 2 and 6 when measured at 25 ℃, when measured at 25 ℃ _a The value is obtained.

In certain embodiments, the aerosol generating material or amorphous solid comprises a gelling agent comprising a cellulose gelling agent and/or a non-cellulose gelling agent, an active, and an acid.

In some cases, the amorphous solid can be a hydrogel and contain less than about 20, 15, 12, or 10 weight percent water calculated on a Wet Weight (WWB) basis. In some cases, the amorphous solid may comprise at least about 1wt%, 2wt%, or 5wt% water (WWB). The amorphous solid comprises from about 1wt% to about 15wt% or from about 5wt% to about 15wt% water, calculated on a wet weight basis. Suitably, the water content of the amorphous solid may be from about 5wt%, 7wt% or 9wt% to about 15wt%, 13wt% or 11wt% (WWB), most suitably about 10wt%.

The amorphous solid may be made from a gel, and such gel may additionally comprise a solvent, comprising 0.1 to 50wt% of the solvent. However, the inventors have determined that solvents containing soluble flavoring agents may reduce gel stability, and that the flavoring agents may crystallize out of the gel. Thus, in some cases, the gel does not contain a solvent in which the flavoring agent can be dissolved.

In some cases, the amorphous solid contains 1 to 60wt% filler, for example 5 to 50wt%, 10 to 40wt%, or 15 to 30wt% filler. In some such cases, the amorphous solid comprises at least 1wt% filler, e.g., at least 5wt%, at least 10wt%, at least 20wt%, at least 30wt%, at least 40wt%, or at least 50wt% filler.

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

In other embodiments, the amorphous solid comprises less than 20wt%, suitably less than 10wt% or less than 5wt% filler. In some cases, the amorphous solid contains less than 1wt% filler, and in some cases, no filler.

The filler (if present) may comprise one or more inorganic filler materials such as calcium carbonate, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulphate, magnesium carbonate and suitable inorganic adsorbents such as molecular sieves. The filler may comprise one or more organic filler materials such as wood pulp, cellulose and cellulose derivatives such as methyl cellulose, hydroxypropyl cellulose and carboxymethyl cellulose (CMC). In some cases, the amorphous solid contains less than 1wt% filler, and in some cases, no filler. In particular, in some cases, the amorphous solid does not comprise calcium carbonate such as chalk.

In a particular embodiment comprising a filler, the filler is fibrous. For example, the filler may be a fibrous organic filler such as wood pulp, cellulose or cellulose derivatives such as methyl cellulose, hydroxypropyl cellulose and carboxymethyl cellulose (CMC). Without wishing to be bound by theory, it is believed that the inclusion of fibrous fillers in the amorphous solid may increase the tensile strength of the material.

In some embodiments, the amorphous solid does not include tobacco fiber. In a particular embodiment, the amorphous solid does not comprise a fibrous material.

In some embodiments, the aerosol generating material does not comprise tobacco fibres. In particular embodiments, the aerosol generating material does not comprise a fibrous material.

In some embodiments, the aerosol generating material does not comprise tobacco fibres. In particular embodiments, the aerosol generating material does not comprise fibrous material.

In some embodiments, the consumable does not include tobacco fiber. In a particular embodiment, the consumable does not comprise a fibrous material.

The aerosol generating material comprising the amorphous solid may have any suitable areal density, such as 30g/m ² To 120g/m ² . In some embodiments, the aerosol generating material may have about 30 to 70g/m ² Or about 40 to 60g/m ² The area density of (a). In some embodiments, the amorphous solid may have about 80 to 120g/m ² Or about 70 to 110g/m ² Or specifically about 90 to 110g/m ² The area density of (a).

In some examples, an amorphous solid in sheet form (sheet form) may have a tensile strength of about 200N/m to about 900N/m. In some examples, such as when the amorphous solid does not include a filler, the amorphous solid may have a tensile strength of 200N/m to 400N/m, or 200N/m to 300N/m, or about 250N/m. In some examples, for example when the amorphous solid comprises a filler, the amorphous solid may have a tensile strength of 600N/m to 900N/m, or 700N/m to 900N/m, or about 800N/m.

The amorphous solid may comprise a colorant. The addition of a colorant can change the visual appearance of the amorphous solid. The presence of the colorant in the amorphous solid may enhance the visual appearance of the amorphous solid and the aerosol generating material. By adding a colorant to the amorphous solid, the amorphous solid may be color matched to other components of the aerosol generating material or to other components of an article comprising the amorphous solid.

A variety of colorants can be used depending on the desired color of the amorphous solid. The color of the amorphous solid may be, for example, white, green, red, purple, blue, brown, or black. Other colors are also contemplated. Natural or synthetic colorants such as natural or synthetic dyes, food grade colorants, and pharmaceutical grade colorants may be used. In certain embodiments, the colorant is caramel, which may impart a brown appearance to the amorphous solid. In such embodiments, the color of the amorphous solid may be similar to the color of other components in the aerosol generating material comprising the amorphous solid (such as the tobacco material). In some embodiments, the colorant is added to the amorphous solid such that it is visually indistinguishable from the other components in the aerosol generating material.

The colorant may be incorporated during the formation of the amorphous solid (e.g., when forming a slurry comprising the material forming the amorphous solid) or it may be applied to the amorphous solid after the amorphous solid is formed (e.g., by spraying it onto the amorphous solid).

Method of manufacturing a consumable

providing a vector;

depositing at least two discrete portions of a slurry on a carrier, the slurry comprising a gelling agent; an aerosol former; and at least one of an active, a flavoring agent, and an acid;

forming a consumable;

-0.5-60wt% of a gelling agent;

-0-80wt% of an aerosol-forming material; and

The embodiments described throughout this application in relation to the consumable of the present invention are in principle also applicable to the method of manufacturing the consumable.

The invention also comprises the use of a consumable as described throughout the present application in a non-combustible aerosol provision device, wherein the device is arranged to generate an aerosol from the consumable when the consumable is used with the non-combustible aerosol provision device.

The embodiments described throughout this application in connection with the consumable of the invention are in principle also applicable to the use of the consumable.

Consumable product

In some cases, the aerosol-generating materials (e.g., the first and second aerosol-generating materials) are attached to a carrier. Advantageously, the support is a planar support. In some cases, the carrier may be substantially or completely impermeable to gases and/or aerosols. This prevents the aerosol or gas from passing through the carrier, thereby controlling the flow rate and ensuring good delivery to the user. This may also be used to prevent condensation or other deposition of gas/aerosol on the surface of a heater, for example provided in a non-combustible aerosol supply system, in use. Therefore, in some cases, consumption efficiency and hygiene can be improved.

Accordingly, in certain embodiments, the present invention provides a consumable for use in a non-combustible aerosol provision system, the consumable comprising:

a carrier;

a first aerosol generating material attached to a support; and

a second aerosol generating material attached to the carrier,

wherein each aerosol-generating material comprises an amorphous solid comprising:

-0.5-60wt% of a gelling agent;

-0-80wt% of an aerosol-forming material; and

wherein the weights are calculated on a dry weight basis; and is

Wherein the composition of the amorphous solid of the first aerosol generating material is different from the amorphous solid of the second aerosol generating material.

The support may be at least partially porous in the region adjacent the surface of the amorphous solid. The inventors have found that such a vector is particularly suitable for use in the present invention; the porous region of the support adjoins the amorphous solid and forms a strong bond. The amorphous solid is formed by drying the gel, and without being limited by theory, it is believed that the slurry forming the amorphous solid partially impregnates the porous material of the support such that when the amorphous solid solidifies and forms crosslinks, the support is partially incorporated into the amorphous solid. This provides a strong bond between the amorphous solid and the support.

In addition, the surface roughness may contribute to the bonding strength between the amorphous solid and the support. The inventors have found that the paper roughness (for the surface abutting the aerosol generating material) may suitably be in the range 50-1000Bekk seconds, suitably 50-150Bekk seconds, suitably 100Bekk seconds (measured in an air pressure interval of 50.66-48.00 kPa). (Bekk smoothness tester is an instrument for determining the smoothness of a paper surface, in which air at a given pressure leaks between a smooth glass surface and a paper sample, and the time (in seconds) for a fixed volume of air to seep between these surfaces is "Bekk smoothness")

Conversely, the surface of the support facing away from the amorphous solid may be placed in contact with the heater, and a smoother surface may provide more efficient heat transfer. Thus, in some cases, the support is configured to have a rougher side adjacent the amorphous solid and a smoother side facing away from the amorphous solid.

In one particular case, the support itself may be a laminate structure. For example, it may comprise a cardboard-backed foil; the paperboard layer is contiguous with the amorphous solid and the properties discussed in the previous paragraph are provided by this contiguity. The foil backing is substantially impermeable, controlling the aerosol flow path. The metal foil backing may also be used to conduct heat to the amorphous solid.

In another case, the foil layer of the cardboard backing foil is contiguous with the amorphous solid. The foil is substantially impermeable, thereby preventing water provided by the amorphous solid from being absorbed into the paper, which can weaken the structural integrity of the paper.

In some cases, the carrier is formed from or includes a metal foil (such as aluminum foil). The metal support may allow better conduction of thermal energy to the amorphous solid. Additionally or alternatively, the metal foil may be used as a susceptor in an induction heating system. In a particular embodiment, the carrier comprises a metal foil layer and a carrier layer, such as paperboard. In these embodiments, the metal foil layer may have a thickness of less than 20 μm, such as from about 1 μm to about 10 μm, suitably about 5 μm.

The consumable may alternatively be referred to herein as a cartridge (cartridge). The consumable may be suitable for use in a THP, a mixing device or another aerosol generating device. In some cases, the consumable may be in the form of a stick. In some cases, as previously described, the consumable may additionally include a filter and/or a cooling element. In some cases, the consumable may be surrounded by a packaging material (such as paper).

The consumable may additionally comprise a ventilation aperture (vent). These may be provided in the side walls of the consumable. In some cases, the vent may be provided in the filter and/or the cooling element. The holes may allow cold air to be drawn into the consumable during use, which may mix with the hot volatile components, thereby cooling the aerosol.

Aeration enhances the production of visible hot volatile components from the consumable when it is heated in use. The hot volatile components are made visible by the process of cooling the hot volatile components so that supersaturation of the hot volatile components occurs. The hot volatile component then undergoes droplet formation (also referred to as nucleation), and eventually the aerosol particles of the hot volatile component increase in size due to further condensation of the hot volatile component and due to condensation of the newly formed droplets by the hot volatile component.

In some cases, the ratio of cool air to the sum of the hot volatile components and cool air (referred to as the aeration ratio) is at least 15%. An aeration ratio of 15% makes it possible to make the thermally volatile components visible by the method described above. The visibility of the thermally volatile components enables the user to recognize that volatile components have been generated and to increase the sensory experience of the smoking experience.

In another example, the aeration ratio is between 50% and 85% to provide additional cooling to the thermally volatile components. In some cases, the aeration ratio may be at least 60% or 65%.

Referring to fig. 1 and 2, a partially cut-away cross-sectional view and a perspective view of an example of an aerosol generating consumable 101 are shown. The consumable 101 is adapted for use with a device having a power source and a heater. The consumable 101 of this embodiment is particularly suitable for use with the apparatus 51 shown in figures 5 to 7 described below. In use, the consumable 101 may be removably inserted into the device shown in fig. 5 at the insertion point 20 of the device 51.

The consumable 101 of one example is in the form of a substantially cylindrical rod comprising a body of aerosol generating material 103 and a filter assembly 105 in the form of a rod. The aerosol generating material comprises an amorphous solid material as described herein. In some embodiments, it may be included in the form of a sheet. In some embodiments, it may be included in the form of shredded sheets. In some embodiments, the aerosol generating material described herein may be incorporated in sheet form and in shredded form.

The filter assembly 105 includes three sections: a cooling section 107, a filtering section 109, and a mouth end section 111. The consumable 101 has a first end 113 (also referred to as the mouth end or proximal end) and a second end 115 (also referred to as the distal end). The body of aerosol-generating material 103 is located towards the distal end 115 of the consumable 101. In one example, the cooling section 107 is positioned adjacent the body of aerosol generating material 103 between the body of aerosol generating material 103 and the filtering section 109 such that the cooling section 107 is in abutting relationship with the aerosol generating material 103 and the filtering section 103. In other examples, there may be a space between the body of aerosol generating material 103 and the cooling section 107 and between the body of aerosol generating material 103 and the filtering section 109. The filter section 109 is located between the cooling section 107 and the mouth end section 111. The mouth end section 111 is located towards the proximal end 113 of the consumable 101, adjacent to the filter section 109. In one example, the filter section 109 is in an abutting relationship with the mouth end section 111. In one embodiment, the overall length of filter assembly 105 is between 37mm and 45mm, and more preferably, the overall length of filter assembly 105 is 41mm.

In one example, the length of the rod of aerosol-generating material 103 is between 34mm and 50mm, suitably between 38mm and 46mm, suitably 42mm in length.

In one example, the total length of the consumable 101 is between 71mm and 95mm, suitably between 79mm and 87mm, suitably 83mm.

An axial end of the body of aerosol-generating material 103 is visible at the distal end 115 of the consumable 101. However, in other embodiments, the distal end 115 of the consumable 101 may comprise an end member (not shown) covering an axial end of the body of aerosol generating material 103.

The body of aerosol generating material 103 is attached to the filter assembly 105 by annular tipping paper (not shown) which is located substantially around the periphery of the filter assembly 105 so as to surround the filter assembly 105 and extend partially along the length of the body of aerosol generating material 103. In one example, the tipping paper is made of 58GSM standard tipping base paper. In one example, the tipping paper has a length of between 42mm and 50mm, suitably 46 mm.

In one example, the cooling section 107 is an annular tube and is positioned around and defines an air gap within the cooling section. The air gap provides a chamber for the flow of hot volatile components generated from the body of aerosol generating material 103. The cooling section 107 is hollow to provide a chamber for aerosol accumulation and is sufficiently rigid to withstand axial compression forces and bending moments that may occur during manufacture and use of the consumable 101 when inserted into the apparatus 51. In one example, the thickness of the wall of the cooling section 107 is approximately 0.29mm.

The cooling section 107 provides physical displacement between the aerosol generating material 103 and the filtering section 109. The physical displacement provided by the cooling section 107 will provide a thermal gradient over the length of the cooling section 107. In one example, the cooling section 107 is configured to provide a temperature difference of at least 40 degrees celsius between the thermally volatile components entering a first end of the cooling section 107 and the thermally volatile components exiting a second end of the cooling section 107. In one example, the cooling section 107 is configured to provide a temperature difference of at least 60 degrees celsius between the thermally volatile components entering a first end of the cooling section 107 and the thermally volatile components exiting a second end of the cooling section 107. This temperature difference over the length of the cooling element 107 protects the temperature sensitive filter section 109 from the high temperature of the aerosol generating material 103 when the aerosol generating material 103 is heated by the device 51. If no physical displacement is provided between the filtering section 109 and the body of aerosol generating material 103 and the heating element of the apparatus 51, the temperature sensitive filtering section 109 may be damaged in use and therefore will not be able to effectively perform the required function.

In one example, the length of the cooling section 107 is at least 15mm. In one example, the length of the cooling section 107 is between 20mm and 30mm, more specifically 23mm to 27mm, more specifically 25mm to 27mm, suitably 25mm.

The cooling section 107 is made of paper, which means that it contains a material that does not produce a compound of interest, such as a toxic compound, when used adjacent to the heater of the device 51. In one example, the cooling section 107 is fabricated from a spirally wound paper tube that provides a hollow interior chamber but remains mechanically rigid. The spirally wound paper tube is capable of meeting the stringent dimensional accuracy requirements of high speed manufacturing processes in terms of tube length, outer diameter, roundness, and straightness.

In another example, the cooling section 107 is a depression created by a hard plug wrap or tipping paper. The rigid plug wrap or tipping paper is manufactured to be sufficiently rigid to withstand axial compression forces and bending moments that may occur during manufacture and during use of the consumable 101 inserted into the device 51.

The filter section 109 may be formed from any filter material sufficient to remove one or more volatilized compounds from the thermally volatilized components of the aerosol generating material. In one example, the filter section 109 is made of a monoacetate material (such as cellulose acetate). The filtration section 109 cools the hot volatiles and reduces their irritation, but does not consume the amount of hot volatiles to a level that is unsatisfactory to the user.

In some embodiments, a capsule (not shown) may be provided in the filtration section 109. It may be arranged substantially centrally in the filter section 109, both across the entire diameter of the filter section 109 and along the length of the filter section 109. In other cases, it may be offset in one or more dimensions. In some cases, when present, the capsule may contain volatile components, such as flavoring agents or aerosol generating agents.

The density of the cellulose acetate tow material of the filtration section 109 controls the pressure drop across the filtration section 109, which in turn controls the draw resistance of the consumable 101. Therefore, the selection of the material of the filter section 109 is important in controlling the draw resistance of the consumable 101. Furthermore, the filtering section performs a filtering function in the consumable 101.

In one example, the filtration section 109 is made of 8Y15 grade filter tow material that provides a filtration effect on the hot volatiles while also reducing the size of condensed aerosol droplets generated by the hot volatiles.

The presence of the filtering section 109 provides an insulating effect by further cooling the hot volatiles exiting the cooling section 107. This further cooling effect reduces the contact temperature of the user's lips on the surface of the filter section 109.

In one example, the length of the filtration section 109 is between 6mm and 10mm, suitably 8mm.

The mouth end section 111 is an annular tube that is positioned around the air gap in the mouth end section 111 and defines the air gap in the mouth end section 111. The air gap provides a chamber for the hot volatile components flowing from the filter section 109. The mouth end section 111 is hollow to provide a chamber for aerosol accumulation, but is sufficiently rigid to withstand axial compression forces and bending moments that may occur during manufacture and use in inserting a consumable into the device 51. In one example, the thickness of the wall of the mouth end section 111 is about 0.29mm. In one example, the length of the mouth end section 111 is between 6mm and 10mm, suitably 8mm.

The mouth end section 111 may be manufactured from a spirally wound paper tube that provides a hollow interior chamber but maintains a critical mechanical stiffness. The spirally wound paper tube is capable of meeting the stringent dimensional accuracy requirements of high speed manufacturing processes in terms of tube length, outer diameter, roundness, and straightness.

The mouth end section 111 provides the function of preventing any liquid condensate accumulating at the outlet of the filtering section 109 from coming into direct contact with the user.

It should be understood that in one example, the mouth end section 111 and the cooling section 107 may be formed from a single tube, and the filtration section 109 is located within the tube separating the mouth end section 111 and the cooling section 107.

Referring to fig. 3 and 4, a partially cut-away section and perspective view of an example of a consumable 301 is shown. The reference numerals shown in fig. 3 and 4 are identical to those shown in fig. 1 and 2, but with increments of 200.

In the example of the consumable 301 shown in fig. 3 and 4, a vent region 317 is provided in the consumable 301 to enable air to flow from outside the consumable 301 into the interior of the consumable 301. In one example, the vent region 317 takes the form of one or more vent holes 317 formed through an outer layer of the consumable 301. These vents may be located in the cooling section 307 to help cool the consumable 301. In one example, the vent region 317 comprises one or more rows of apertures, and preferably each row of apertures is arranged circumferentially around the consumable 301 in a cross-section substantially perpendicular to the longitudinal axis of the consumable 301.

In one example, there are between one and four rows of vent holes to provide venting for the consumable 301. Each row of vents may have 12 to 36 vents 317. The diameter of the vent 317 may be, for example, between 100 μm and 500 μm. In one example, the axial spacing between each row of vent holes 317 is between 0.25mm and 0.75mm, suitably 0.5mm.

In one example, the vent holes 317 are uniformly sized. In another example, the vent holes 317 are different sizes. The vent holes may be made using any suitable technique (e.g., one or more of the following techniques): laser techniques, mechanical perforation of cooling section 307, or pre-perforation of cooling section 307 prior to forming consumable 301. The vent 317 is positioned to provide effective cooling of the consumable 301.

In one example, each row of vent holes 317 is located at least 11mm from the proximal end 313 of the consumable, suitably between 17mm and 20mm from the proximal end 313 of the consumable 301. The vent 317 is positioned such that the user does not block the vent 317 when the consumable 301 is in use.

As can be seen in fig. 6 and 7, providing a vent row between 17mm and 20mm from the proximal end 313 of the consumable 301 enables the vent 317 to be located outside the device 51 when the consumable 301 is fully inserted into the device 51. By locating the vent on the exterior of the device, unheated air can enter the consumable 301 from the exterior of the device 51 through the vent to assist in cooling the consumable 301.

The length of the cooling section 307 is such that when the consumable 301 is fully inserted into the apparatus 51, the cooling section 307 will be partially inserted into the apparatus 51. The length of the cooling section 307 provides a first function of providing a physical gap between the heater arrangement and the heat sensitive filter arrangement 309 of the device 51, and a second function of enabling the vent 317 to be located in the cooling section whilst also being located outside of the device 51 when the consumable 301 is fully inserted into the device 51. As can be seen from fig. 6 and 7, most of the cooling element 307 is located within the device 51. However, a portion of the cooling element 307 extends out of the device 51. A vent 317 is located in the portion of the cooling element 307 that extends out of the device 51.

Referring now in more detail to figures 5 to 7, there is shown one example of an apparatus 51 arranged to heat an aerosol generating material to volatilise at least one component of the aerosol generating material, typically to form an aerosol which can be inhaled. The device 51 is a heating device that releases the compound by heating but not burning the aerosol generating material.

The first end 53 is sometimes referred to herein as the mouth or proximal end 53 of the device 51, and the second end 55 is sometimes referred to herein as the distal end 55 of the device 51. The device 51 has an on/off button 57 to allow the device 51 as a whole to be turned on and off as desired by the user.

The device 51 includes a housing 59 for locating and protecting various internal components of the device 51. In the example shown, the housing 59 comprises a one-piece sleeve 11 that surrounds the perimeter of the device 51, covered with a top panel 17 that generally defines the 'top' of the device 51 and a bottom panel 19 that generally defines the 'bottom' of the device 51. In another example, the housing includes, in addition to the top panel 17 and the bottom panel 19, a front panel, a rear panel, and a pair of opposing side panels.

The top panel 17 and/or the bottom panel 19 may be removably secured to the one-piece sleeve 11 to allow easy access to the interior of the device 51, or may be "permanently" secured to the one-piece sleeve 11, for example, to prevent a user from accessing the interior of the device 51. In one example, the

panels

17 and 19 are made of a plastic material including glass filled nylon, for example, formed by injection molding, and the unitary sleeve 11 is made of aluminum, although other materials and other manufacturing processes may be used.

The top panel 17 of the device 51 has an opening 20 at the mouth end 53 of the device 51 through which, in use, a consumable 101, 301 comprising aerosol generating material may be inserted into the device 51 and removed from the device 51 by a user.

A heater arrangement 23, control circuitry 25 and a power supply 27 are located or secured within the housing 59. In this example, the heater arrangement 23, control circuit 25 and power supply 27 are laterally adjacent (i.e. adjacent when viewed from the end), the control circuit 25 typically being located between the heater arrangement 23 and the power supply 27, but other locations are possible.

The control circuit 25 may comprise a controller, such as a microprocessor arrangement, constructed and arranged to control heating of the aerosol generating material in the consumable 101, 301, as discussed further below.

The power source 27 may be, for example, a battery, which may be a rechargeable battery or a non-rechargeable battery. Examples of suitable batteries include, for example, lithium ion batteries, nickel batteries (such as nickel cadmium batteries), alkaline batteries, and the like. The battery 27 is electrically coupled to the heater arrangement 23 to supply power to heat the aerosol generating material in the consumable (to volatilise the aerosol generating material without burning the aerosol generating material as discussed) when required and under the control of the control circuit 25.

An advantage of locating the power supply 27 laterally adjacent to the heater arrangement 23 is that a physically large power supply 25 can be used without making the device 51 as a whole too long. It will be appreciated that, typically, a physically large power source 25 has a higher capacity (i.e., the total power that can be supplied, typically measured in amp-hours, etc.), so the battery life of the device 51 may be longer.

In one example, the heater arrangement 23 is generally in the form of a hollow cylindrical tube having a hollow interior heating chamber 29 into which a consumable 101, 301 comprising aerosol generating material is inserted for heating in use. Different arrangements for the heater arrangement 23 are possible. For example, the heater arrangement 23 may comprise a single heating element or may be formed by a plurality of heating elements aligned along a longitudinal axis of the heater arrangement 23. The or each heating element may be annular or tubular, or at least part-annular or part-tubular around its circumference. In one example, the or each heating element may be a thin film heater. In another example, the or each heating element may be made of a ceramic material. Examples of suitable ceramic materials include alumina and aluminum nitride and silicon nitride ceramics, which may be laminated and sintered. Other heating arrangements are possible, including, for example, inductive heating, infrared heater elements heated by emitting infrared radiation, or resistive heating elements formed from, for example, resistive electrical windings.

In one specific example, the heater arrangement 23 is supported by a stainless steel carrier tube and comprises a polyimide heating element. The heater arrangement 23 is dimensioned such that when a consumable 101, 301 is inserted into the device 51, substantially the entire body of

aerosol generating material

103, 303 of the consumable 101, 301 is inserted into the heater arrangement 23.

The or each heating element may be arranged such that selected regions of the aerosol generating material may be heated independently, for example sequentially (over time, as discussed above) or together (simultaneously) as required.

In this example, the heater arrangement 23 is surrounded along at least a portion of its length by a thermal insulator 31. The insulator 31 helps to reduce the amount of heat transferred from the heater arrangement 23 to the exterior of the device 51. This helps to reduce the power requirements of the heater arrangement 23 as it reduces heat losses overall. The insulator 31 also helps to keep the exterior of the device 51 cool during operation of the heater arrangement 23. In one example, the insulator 31 may be a double-walled sleeve that provides a low pressure region between the two walls of the sleeve. That is, the insulator 31 may be, for example, a "vacuum" tube, i.e., a tube that has been at least partially evacuated to minimize heat transfer by conduction and/or convection. Other arrangements of the insulator 31 are possible, including the use of insulating materials, including, for example, suitable foam-type materials in addition to or in lieu of a double-walled sleeve.

The housing 59 may further include various internal carrier structures 37 for supporting all internal components and the heating arrangement 23.

The apparatus 51 further comprises a collar 33 (collar) extending around the opening 20 and projecting from the opening 20 into the interior of the housing 59 and a generally tubular chamber 35 located between the collar 33 and one end of the vacuum sleeve 31. The chamber 35 further includes a cooling structure 35f, which in this example comprises a plurality of cooling fins 35f spaced along the outer surface of the chamber 35, and each cooling fin is arranged circumferentially around the outer surface of the chamber 35. When the consumable 101, 301 is inserted into the device 51 over at least a portion of the length of the hollow chamber 35, there is an air gap 36 between the hollow chamber 35 and the consumable. The air gap 36 surrounds the entire circumference of the consumable 101, 301 over at least a portion of the cooling section 307.

Collar 33 includes a plurality of ridges 60 circumferentially arranged about the periphery of opening 20 and projecting into opening 20. The ridge 60 occupies space within the opening 20 such that the opening 20 has an opening span at the location of the ridge 60 that is less than the opening span of the opening 20 at locations without the ridge 60. The ridge 60 is configured to engage with a consumable 101, 301 inserted into the device to help secure the consumable within the device 51. The open space (not shown in the figures) defined by adjacent pairs of ridges 60 and

consumables

101, 301 forms a vent path around the exterior of the

consumables

101, 301. These vent paths allow hot vapor escaping from the consumable 101, 301 to exit the device 51 and allow cooling air to flow in the air gap 36 into the device 51 around the consumable 101, 301.

In operation, as shown in fig. 5-7, the consumable 101, 301 is removably inserted into the insertion point 20 of the device 51. Referring specifically to fig. 6, in one example, the body of

aerosol generating material

103, 303 located towards the

distal end

115, 315 of the consumable 101, 301 is received entirely within the heater arrangement 23 of the device 51. The

proximal end

113, 313 of the consumable 101, 301 extends from the device 51 and acts as a mouthpiece component for the user.

In operation, the heater arrangement 23 will heat the consumable 101, 301 to volatilize at least one component of the aerosol generating material from the body of

aerosol generating material

103, 303.

The primary flow path of the hot volatile components from the body of

aerosol generating material

103, 303 is axially through the consumable 101, 301, through the chamber inside the

cooling section

107, 307, through the

filtering section

109, 309, through the

mouth end section

111, 313 to the user. In one example, the temperature of the hot volatile components generated by the body of aerosol generating material is between 60 ℃ and 250 ℃, which may be above the acceptable inhalation temperature for the user. As the hot volatile components travel through the cooling

sections

107, 307, they will cool and some of the volatile components will condense on the inner surfaces of the cooling

sections

107, 307.

In the example of the consumable 301 shown in fig. 3 and 4, cold air will be able to enter the cooling section 307 via vents 317 formed in the cooling section 307. The cooling air will mix with the hot volatiles to provide additional cooling to the hot volatiles.

Advantageously, the consumable of the present invention allows each of the first and second aerosol generating materials to be aerosolized separately. In other words, the generation of aerosols from each aerosol generating material may be under separate control, such that the generation of aerosols generated by each aerosol generating material may be varied separately. In embodiments where the non-combustible aerosol provision system uses heat to generate the aerosol, each aerosol generating material in the consumable may be under the control of a separate heat generating arrangement. In such embodiments, the temperature of each aerosol generating material may be controlled individually to stimulate the release of a desired amount of aerosol from each aerosol generating material. In this way, the non-combustible aerosol provision system is adapted to allow a user to aerosolize the first and/or second aerosol generating material according to personal preference. As a non-limiting example provided to illustrate the present invention, the amorphous solid of the first aerosol generating material may comprise a flavorant but no active, while the amorphous solid of the second aerosol generating material may comprise an active but no flavorant; if the user only wants to inhale a scent, the non-combustible aerosol provision system may allow this; for example, a user may program a non-combustible aerosol provision device to aerosolize a first aerosol generating material (comprising a flavouring agent) but not a second aerosol generating material (comprising an active substance). It will be appreciated that such a system may be further configured to allow a user to obtain a wide variety of smoking experiences, depending on preferences.

In some embodiments, the aerosol generating material is arranged in the consumable such that when used within the non-combustible aerosol provision system, they can be stimulated to generate aerosols under control separate from each other.

The consumable of the present invention has the advantage that a single production line or facility can produce a single type of consumable, providing multiple experiences according to user preferences.

In some cases, a heater (e.g., in a non-flammable aerosol supply system) may heat, but not burn, the amorphous solid to between 120 ℃ and 350 ℃ in use. In some cases, in use, the heater may heat the amorphous solid to between 140 ℃ and 250 ℃ without combusting.

The heater may comprise one or more resistive heaters including, for example, one or more nichrome resistive heaters and/or one or more ceramic heaters. The one or more heaters may comprise one or more induction heaters comprising an arrangement comprising one or more susceptors which may form a chamber into which an article comprising an aerosol generating material is inserted or otherwise positioned in use. Alternatively or additionally, one or more susceptors may be provided in the aerosol generating material. Other heating arrangements may also be used.
