An aerosol generating material is a material that is capable of generating an aerosol, for example when heated, radiated or energized in any other way. The aerosol-generating material may, for example, be in solid, liquid or gel form, which may or may not contain an active and/or a flavourant. In some embodiments, the aerosol-generating material may comprise an "amorphous solid," which may alternatively be referred to as a "monolithic solid" (i.e., non-fibrous). In some embodiments, the amorphous solid may be a dried gel. An amorphous solid is a solid material that can retain some fluid (such as a liquid) therein. In some embodiments, the aerosol-generating material may, for example, comprise from about 50 wt%, 60 wt% or 70 wt% amorphous solids to about 90 wt%, 95 wt% or 100 wt% amorphous solids.

The aerosol-generating material may comprise one or more active substances and/or flavourants, one or more aerosol-former materials and optionally one or more other functional materials.

The aerosol former material may comprise one or more components capable of forming an aerosol. In some embodiments, the aerosol former material may include one or more of glycerol (glycerin), glycerin (glycerol), propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1, 3-butylene glycol, erythritol, meso-erythritol, ethyl vanilate, ethyl laurate, diethyl suberate, triethyl citrate, glyceryl triacetate, a mixture of diacetate, benzyl benzoate, benzyl acetate phenyl acetate, glyceryl tributyrate, lauryl acetate, lauric acid, myristic acid, and propylene carbonate. In other embodiments, the aerosol former comprises one or more polyols, such as 1, 3-butanediol; esters of polyhydric alcohols (such as glycerol monoacetate, diacetate, or triacetate); and/or aliphatic esters of monocarboxylic, dicarboxylic or polycarboxylic acids (such as dimethyl dodecanedioate and dimethyl tetradecanedioate).

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.

The material may be present on a support or in a carrier to form a substrate. For example, the support may be or include paper, card, cardboard, reconstituted material, a plastic material, a ceramic material, a composite material, glass, metal, or a metal alloy. In some embodiments, the support comprises a susceptor. In some embodiments, the susceptor is embedded within the material. In some alternative embodiments, the susceptor is on one or both sides of the material.

A consumable is an article comprising or consisting of an aerosol-generating material, some or all of which is intended to be consumed by a user during use. The consumable may comprise one or more other components, such as an aerosol-generating material storage region, an aerosol-generating material delivery component, an aerosol-generating region, a housing, a wrapper, a mouthpiece, a filter, and/or an aerosol modifier. The consumable may also comprise an aerosol generator, such as a heater, which generates heat to cause the aerosol generating material to generate an aerosol in use. The heater may for example comprise a combustible material, a material heatable by electrical conduction or a susceptor.

Susceptors are materials that can be heated by penetrating them with a changing magnetic field, such as an alternating magnetic field. The susceptor may be an electrically conductive material such that penetration of the susceptor by a varying magnetic field causes induction heating of the heating material. The heating material may be a magnetic material such that it penetrates the heating material with a varying magnetic field causing hysteresis heating of the heating material. The susceptor may be electrically conductive and magnetic such that the susceptor may be heated by two heating mechanisms. Herein, a device configured to generate a varying magnetic field is referred to as a magnetic field generator.

An aerosol-modifying agent is a substance, typically located downstream of the aerosol-generating region, that is configured to modify the generated aerosol, for example by changing the taste, flavour, acidity or other characteristics of the aerosol. The aerosol modifier may be disposed in an aerosol modifier release member operable to selectively release the aerosol modifier.

The aerosol modifier may be, for example, an additive or an adsorbent. The aerosol modifier may, for example, comprise one or more of a fragrance, a colorant, water, and a carbon sorbent. The aerosol modifier may be, for example, a solid, liquid, or gel. The aerosol modifier may be in the form of a powder, a thread or a granule. The aerosol modifier may be free of filter material.

An aerosol generator is a device configured to generate an aerosol from an aerosol generating material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol generating material to thermal energy in order to release one or more volatiles from the aerosol generating material to form an aerosol. In some embodiments, the aerosol generator is configured to generate an aerosol from the aerosol-generating material without heating. For example, the aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.

The aerosol-generating material may comprise a carrier on which the amorphous solid is disposed. The support serves as a support on which the amorphous solid is formed, thereby being easy to manufacture. The support may provide tensile strength to the amorphous solid layer, thereby facilitating handling.

The mouthpiece of the article may comprise an amorphous solid material, suitably in the form of an aggregated sheet of amorphous solid material.

The present invention provides a mouthpiece comprising an amorphous solid material. It has surprisingly been found that the inclusion of an amorphous solid material in the mouthpiece results in improved aerosol, with desirable flavour characteristics and/or reduced temperature, thereby improving the user's perception.

In this case, the amorphous solid material is a sheet, optionally in aggregated, wound or coiled form. In some cases, the sheet material may be incorporated into the mouthpiece in the form of a sheet material. In other cases, the sheet material may be shredded and then incorporated into the mouthpiece.

The aerosol-generating material comprising the amorphous solid may have any suitable areal density, such as from 30g/m ² To 120g/m ² . In some cases, the sheet can have 80 to 120g/m ² Or from about 70 to 110g/m ² Or in particular from about 90 to 110g/m ² Or suitably about 100g/m ² Mass per unit area of (d).

In some embodiments, the amorphous solid in sheet form may have a tensile strength of from about 200N/m to about 900N/m. In some embodiments, such as when the amorphous solid does not contain a filler, the amorphous solid may have a tensile strength of from 200N/m to 400N/m, or from 200N/m to 300N/m, or about 250N/m.

In some embodiments, such as when the amorphous solid comprises a filler, the amorphous solid may have a tensile strength of from 600N/m to 900N/m, or from 700N/m to 900N/m, or about 800N/m. Such tensile strength may be particularly suitable for embodiments wherein the amorphous solid material is included in the aerosol-generating article/component as a rolled sheet, suitably in the form of a tube.

In some cases, the carrier layer 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.

The support may be any suitable material that can be used to support an amorphous solid. In some cases, the carrier may be formed from a material selected from the group consisting of: metal foil, paper, carbon paper, greaseproof paper, ceramics, carbon allotropes (such as graphite and graphene), plastics, cardboard, wood, or combinations thereof. In some cases, the carrier may comprise or consist of a tobacco material (such as a sheet of reconstituted tobacco). In some cases, the carrier may be formed from a material selected from the group consisting of metal foil, paper, cardboard, wood, or a combination thereof. In some cases, the support itself may be a laminate structure comprising a plurality of material layers selected from the above list. In some cases, the carrier may also serve as a fragrance carrier. For example, the carrier may be impregnated with a flavourant or tobacco extract.

In some cases, the surface of the support adjacent to the amorphous solid may be porous. For example, in some cases, the support comprises paper. The inventors have found that porous supports (such as paper) are particularly suitable for use in the present invention; the porous (paper) layer adjoins the amorphous solid layer 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 gel-forming slurry partially impregnates a porous support (such as paper) so that when the gel sets and forms crosslinks, the support is partially incorporated into the gel. This provides a strong bond between the gel and the carrier (and between the dried gel and the carrier).

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

In another case, paper and grease proof paper laminates have also been found to be particularly useful in the present invention. The paper layer is adjacent to the amorphous solid and the tacky amorphous solid does not readily stick to the greaseproof paper carrier backing.

In some cases, the carrier may have a diameter of between about 0.010mm to about 2.0mm, suitably from about 0.015mm, 0.02mm, 0.05mm or 0.1mm to about 1.5mm, 1.0mm or 0.5 mm.

In some cases, the amorphous solid layer may have a thickness of about 0.015mm to about 1.5mm, suitably about 0.05mm to about 1.5mm or 0.05mm to about 1.0 mm. Suitably, the thickness may be in the range of about 0.1mm or 0.15mm to about 1mm, 0.5mm or 0.3 mm. The amorphous solid may comprise more than one layer, and the thickness described herein refers to the aggregate thickness of those layers.

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 include 1 to 60 wt% of a gelling agent, wherein the weights are calculated on a dry weight basis.

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

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 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.

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), gums, 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 the formation of the amorphous solid. In some cases, the amorphous solid may include calcium-crosslinked alginate and/or calcium-crosslinked pectin.

In some embodiments, the gelling agent comprises alginate, and the alginate is present in the amorphous solid in an amount of 10 to 30 wt% (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 amorphous solid may include a gelling agent comprising carrageenan.

Suitably, the amorphous solid may comprise from about 0.1 wt%, 0.5 wt%, 1 wt%, 3 wt%, 5 wt%, 7 wt% or 10% to about 50 wt%, 45 wt%, 40 wt%, 35 wt%, 30 wt% or 25 wt% aerosol generating agent (all calculated on a dry weight basis). The aerosol generating agent may act as a plasticizer. For example, the amorphous solid may comprise 0.5 to 40 wt%, 3 to 35 wt%, or 10 to 25 wt% aerosol generating agent. In some cases, the aerosol-generating agent comprises one or more compounds selected from the group consisting of: erythritol, propylene glycol, glycerol, glyceryl triacetate, sorbitol, and xylitol. In some cases, the aerosol-generating agent comprises, consists essentially of, or consists of glycerol. The inventors have determined that if the content of plasticizer is too high, the amorphous solid can absorb water, resulting in a material that does not produce a proper consumption experience in use. The inventors have demonstrated that if the plasticizer content is too low, the amorphous solid may be brittle and easily broken. The plasticizer content described herein provides amorphous solid flexibility that allows amorphous solid sheets to be wound onto bobbins that are useful in the manufacture of aerosol-generating articles.

The amorphous solid may include a flavoring agent. In some cases, the amorphous solid may comprise up to about 80, 70, 60, 55, 50, or 45 wt% of the flavorant. In some cases, the amorphous solid can include at least about 0.1 wt%, 1 wt%, 10 wt%, 20 wt%, 30 wt%, 35 wt%, or 40 wt% of the flavorant (all calculated on a dry weight basis). For example, the amorphous solid may comprise 1 to 80 wt%, 10 to 80 wt%, 20 to 70 wt%, 30 to 60 wt%, 35 to 55 wt%, or 30 to 45 wt% of the flavorant. In some cases, the flavoring agent comprises, consists essentially of, or consists of menthol.

The amorphous solid may include 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 parts of the article comprising the amorphous solid.

A variety of colorants may 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 can impart a brown appearance to the amorphous solid. In such embodiments, the colour of the amorphous solid may be similar to the colour 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 to make it visually indistinguishable from 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 the colorant may be applied to the amorphous solid after the amorphous solid is formed (e.g., by spraying it onto the amorphous solid).

In some cases, the amorphous solid may additionally comprise an emulsifier that emulsifies the molten flavoring during the manufacturing process. For example, the amorphous solid may comprise from about 5 wt% to about 15 wt%, suitably about 10 wt%, emulsifier (calculated on a dry weight basis). The emulsifier may include gum arabic.

In some embodiments, the amorphous solid is a hydrogel and comprises less than about 20 wt% water, based on wet weight. In some cases, the hydrogel can comprise less than about 15 wt%, 12 wt%, or 10 wt% water, based on wet weight. In some cases, the hydrogel can include at least about 1 wt%, 2 wt%, or at least about 5 wt% water (WWB).

In certain embodiments, the amorphous solid comprises a gelling agent (including a cellulose gelling agent and/or a non-cellulose gelling agent), an active, and an acid.

In some embodiments, the amorphous solid additionally comprises an active substance. For example, in some cases, the amorphous solid additionally comprises tobacco material and/or nicotine. In some cases, the amorphous solid may comprise 5 to 60 wt% (on a dry weight basis) of tobacco material and/or nicotine. In some cases, the amorphous solid can include from about 1 wt%, 5 wt%, 10 wt%, 15 wt%, 20 wt%, or 25 wt% to about 70 wt%, 60 wt%, 50 wt%, 45 wt%, 40 wt%, 35 wt%, or 30 wt% (by dry weight) of the active. In some cases, the amorphous solid can include from about 1 wt%, 5 wt%, 10 wt%, 15 wt%, 20 wt%, or 25 wt% to about 70 wt%, 60 wt%, 50 wt%, 45 wt%, 40 wt%, 35 wt%, or 30 wt% (by dry weight) of the tobacco material. For example, the amorphous solids may comprise 10 to 50 wt%, 15 to 40 wt%, or 20 to 35 wt% of the tobacco material. In some cases, the amorphous solid can include from about 1 wt%, 2 wt%, 3 wt%, or 4 wt% to about 20 wt%, 18 wt%, 15 wt%, or 12 wt% (by dry weight) nicotine. For example, the amorphous solid may comprise 1 to 20 wt%, 2 to 18 wt%, or 3 to 12 wt% nicotine.

In some cases, the amorphous solid comprises an active substance, such as a tobacco extract. In some cases, the amorphous solids can include 5 to 60 wt% (dry weight basis) of the tobacco extract. In some cases, the amorphous solid can include from about 5 wt%, 10 wt%, 15 wt%, 20 wt%, or 25 wt% to about 60 wt%, 50 wt%, 45 wt%, or 40 wt%, 35 wt%, or 30 wt% (by dry weight) of the tobacco extract. For example, the amorphous solid may comprise 10 to 50 wt%, 14 to 40 wt%, or 20 to 35 wt% of the tobacco extract. The tobacco extract can contain nicotine at a concentration such that the amorphous solid comprises from 1 wt%, 1.5 wt%, 2 wt%, or 2.5 wt% to about 6 wt%, 5 wt%, 4.5 wt%, or 4 wt% (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 does comprise nicotine. In some such cases, the amorphous solid can comprise from about 1 wt%, 2 wt%, 3 wt%, or 4 wt% to about 20 wt%, 18 wt%, 15 wt%, or 12 wt% (by dry weight) nicotine. For example, the amorphous solid may comprise 1 to 20 wt%, 2 to 18 wt%, or 3 to 12 wt% nicotine.

In some cases, the total content of active and fragrance can be at least about 0.1 wt%, 1 wt%, 5 wt%, 10 wt%, 20 wt%, 25 wt%, or 30 wt%. In some cases, the total content of active and fragrance can be less than about 90 wt%, 80 wt%, 70 wt%, 60 wt%, 50 wt%, or 40 wt% (all on a dry weight basis).

In some cases, the total content of tobacco material, nicotine, and flavoring can be at least about 0.1 wt%, 1 wt%, 5 wt%, 10 wt%, 20 wt%, 25 wt%, or 30 wt%. In some cases, the total content of active and/or fragrance may be less than about 90 wt%, 80 wt%, 70 wt%, 60 wt%, 50 wt%, or 40 wt% (all on a dry weight basis).

The amorphous solid may be made from a gel, and such gel may additionally comprise a solvent contained at 0.1 to 50 wt%. However, the present inventors have determined that inclusion of a solvent in which the fragrance is soluble may reduce the gel stability, and that the fragrance may crystallize out of the gel. Thus, in some cases, and therefore, in some cases, the gel does not include a solvent in which the fragrance is soluble.

In some embodiments, the amorphous solid comprises less than 60 wt% (such as from 1 wt% to 60 wt%, or 5 wt% to 50 wt%, or 5 wt% to 30 wt%, or 10 wt% to 20 wt%) filler.

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

The filler, if present, may include one or more inorganic filler materials (such as calcium carbonate, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, magnesium carbonate), as well as suitable inorganic adsorbents (such as molecular sieves). The filler may include one or more organic filler materials (such as wood pulp, cellulose, and cellulose derivatives). In some cases, the amorphous solid includes less than 1 wt% 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, hemp, cellulose or cellulose derivatives. 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. This may be particularly advantageous because the increased tensile strength may make it less likely that defects will be introduced into the amorphous solid material during manufacture.

In some embodiments, the amorphous solid does not comprise tobacco fiber. In particular embodiments, 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 cases, the amorphous solid may consist essentially of or consist of a gelling agent, an aerosol generating agent, water, and optionally a flavoring agent and/or a tobacco material and/or a nicotine source.

In some cases, the amorphous solid may consist essentially of or consist of a gelling agent, water, an aerosol generating agent, and optionally a flavoring agent and/or an active.

Induction heating is the process of heating an electrically conductive object by penetrating the object with a varying magnetic field. The process is described by faraday's law of induction and ohm's law. The induction heater may include an electromagnet and a device for passing a varying current (such as an alternating current) through the electromagnet. When the electromagnet and the object to be heated are properly positioned relative to each other such that the resultant varying magnetic field generated by the electromagnet penetrates the object, one or more eddy currents are generated inside the object. The object has resistance to the flow of current. Thus, when such eddy currents are generated in the object, their flow against the electrical resistance of the object causes the object to be heated. This process is known as joule heating, ohmic heating, or resistive heating. An object capable of induction heating is called a susceptor.

In one embodiment, the susceptor is in the form of a closed loop. It has been found that when the susceptor is in the form of a closed loop, the magnetic coupling between the susceptor and the electromagnet is enhanced in use, which results in greater or improved joule heating.

Hysteresis heating is a process of heating an object made of a magnetic material by penetrating the object with a varying magnetic field. Magnetic materials can be considered to contain many atomic-scale magnets or magnetic dipoles. When a magnetic field penetrates such a material, the magnetic dipole aligns with the magnetic field. Thus, when a varying magnetic field (such as, for example, an alternating magnetic field generated by an electromagnet) penetrates a magnetic material, the orientation of the magnetic dipoles changes with the applied varying magnetic field. Such magnetic dipole reorientation results in the generation of heat in the magnetic material.

When an object is both electrically conductive and magnetic, penetrating the object with a varying magnetic field can cause both joule heating and hysteresis heating in the object. Furthermore, the use of magnetic materials may enhance the magnetic field, which may enhance joule heating.

In each of the above processes, since heat is generated within the object itself, rather than by an external heat source through thermal conduction, rapid temperature rise and more uniform heat distribution in the object can be achieved, particularly through selection of appropriate object materials and geometries, and appropriate varying magnetic field sizes and orientations relative to the object. Furthermore, since induction heating and hysteresis heating do not require a physical connection to be provided between the source of the varying magnetic field and the object, design freedom and control over the heating profile may be greater and costs may be lower.

Articles (such as those in the shape of rods) are often named according to product length: "conventional" (typically in the range of 68 to 75mm, for example about 68mm to about 72mm), "short" or "mini" (68mm or less), "extra large" (typically in the range of 75 to 91mm, for example about 79mm to about 88mm), "long" or "super large" (typically in the range of 91 to 105mm, for example about 94mm to about 101mm) and "extra long" (typically in the range of about 110mm to about 121 mm).

They are also named according to product perimeter: "conventional" (about 23 to 25mm), "wide" (greater than 25mm), "thin" (about 22 to 23mm), "semi-thin" (about 19 to 22mm), "ultra-thin" (about 16 to 19mm) and "microfibrous" (less than about 16 mm).

Thus, for example, an article in the form of a king size, extra light and thin will have a length of about 83mm and a circumference of about 17 mm.

Each form may be produced using a different length of mouthpiece. The mouthpiece length will be about 30mm to 50 mm. Tipping paper (tipping paper) attaches the mouthpiece to the aerosol-generating material and will typically have a longer length (e.g. 3mm to 10mm longer) than the mouthpiece such that the tipping paper covers the mouthpiece and overlaps with the aerosol-generating material (e.g. in the form of a base material rod) to attach the mouthpiece to the rod.

The articles described herein and their aerosol-generating materials and mouthpieces may be made in any of the forms described above, but are not limited to.

The terms "upstream" and "downstream" as used herein are relative terms defined with respect to the direction of mainstream aerosol drawn through the article or device in use.

The filamentary tow material described herein may comprise cellulose acetate tow. The filamentary tow may also be formed using other materials used to form fibers, such as polyvinyl alcohol (PVOH), polylactic acid (PLA), Polycaprolactone (PCL), poly (1-4 butanediol succinate) (PBS), poly (butylene adipate-co-terephthalate) (PBAT), starch-based materials, cotton, aliphatic polyester materials, and polysaccharide polymers or combinations thereof. The filamentary tow may be plasticized with a suitable plasticizer for the tow (such as triacetin, where the material is cellulose acetate tow), or the tow may be unplasticized. The tow may be of any suitable gauge, such as fibers having a "Y" shape or other cross section (such as an "X") between 2.5 and 15 denier per filament (e.g., between 8.0 and 11.0 denier per filament), and a total denier value between 5,000 and 50,000 (e.g., between 10,000 and 40,000).

As used herein, the term "tobacco material" refers to any material that includes tobacco or derivatives or substitutes thereof. The term "tobacco material" may include one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes. The tobacco material may include one or more of shredded tobacco, tobacco fibers, cut tobacco, extruded tobacco, tobacco stems, tobacco lamina, reconstituted tobacco, and/or tobacco extracts.

In the drawings described herein, like reference numerals are used to illustrate equivalent features, articles, or components.

Fig. 1 is a side cross-sectional view of an article 1 for use with a non-combustible aerosol provision apparatus. As shown in fig. 1, the article comprises a mouthpiece 2 having an upstream end 2a and a downstream end 2 b. The mouthpiece 2 comprises a body 6 comprising a sheet of amorphous solid material. In this embodiment, the amorphous solid material is gathered and wrapped by the first plug wrap 7 to form a substantially cylindrical body 6. In this embodiment, body 6 is formed from an aggregated sheet of a single amorphous solid material. However, in alternative embodiments, sheets of amorphous solid material may be cut into strips before being gathered to form body 6.

In the embodiment shown in figure 1, the article comprises a mouthpiece 2, and further comprises a cylindrical rod of aerosol generating material 3 (in the present case tobacco material) connected to the mouthpiece 2. The upstream end 2a of the mouthpiece is disposed adjacent the rod 3 of aerosol-generating material and the downstream end 2b of the mouthpiece 2 is disposed away from the rod 3 of aerosol-generating material.

The inventors have found that providing a body of amorphous solid material in a mouthpiece advantageously provides a cooling effect to the aerosol as it is drawn through the mouthpiece in use. Without wishing to be bound by theory, it is hypothesized that as the aerosol passes through the body 6, the heat transferred from the aerosol to the amorphous solid material in use aerosolizes components of the amorphous solid material, resulting in cooling of the aerosol and, advantageously, simultaneously, if desired, altering the ability of the flavour of the aerosol to pass through the mouthpiece. This arrangement can reduce known problems with smoking articles in which the aerosol is too hot when it reaches the lips of the consumer, and also provide means for adding additional flavour to the aerosol without increasing manufacturing complexity.

In this example, the length of the body 6 of amorphous solid material is 40 mm.

The body may be formed using methods known to those skilled in the art for producing paper filters for smoking articles. In this embodiment, the body 6 of amorphous solid material is formed from an aggregated sheet of a single amorphous solid material. In alternative embodiments, the body 6 may be formed from sheets of two or more amorphous solid materials or from sheets of a single material that are cut into strips before being gathered to form the body. In the present case, the amorphous solid material comprises a single layer and is not laminated on the support material. In other embodiments, the amorphous solid material may be laminated on a support material (such as paper or foil), and the laminated amorphous solid material may be used to form a body in any of the manners described herein.

In the present case, the amorphous solid material has a thickness of 0.09 mm. In alternative embodiments, the amorphous solid material may have any suitable thickness as described herein. Suitably, the amorphous solid material may have a thickness in the range 0.05mm to 0.2 mm. Suitably, in any of the embodiments described herein, the amorphous solid layer has a thickness of from about 50 μm to about 200 μm, or from about 50 μm to about 100 μm, or from about 60 μm to about 90 μm, suitably about 77 μm.

The density of the body 6 may be determined by dividing the total weight of the body 6 by the total volume of the body 6, wherein the total volume may be calculated using an appropriate measurement of the body 6 (e.g., using a caliper). If necessary, a microscope may be used to measure the appropriate dimensions. In the present case, the volume has 0.51x 10 ^-3 g/mm ³ The density of (c). In other embodiments, the body may have a thickness of between 0.1x 10 ^-3 g/mm ³ To 1x 10 ^-3 g/mm ³ The density of (d) in between.

The body 6 is wrapped in a first plug wrap 7. Preferably, the first plug wrap 7 has a basis weight of less than 50gsm, more preferably between about 20gsm to 40 gsm. Preferably, the first plug wrap 7 has a thickness of between 30 μm and 60 μm, more preferably between 35 μm and 45 μm. Preferably, the first plug wrap 7 is a non-porous plug wrap, for example, having a permeability of less than 100Coresta units (e.g., less than 50Coresta units). However, in other embodiments, the first plug wrap 7 may be a porous plug wrap, for example, having a permeability greater than 200Coresta units.

Fig. 2 is a side cross-sectional view of an article 1 'for use with a non-combustible aerosol provision apparatus, the article comprising a mouthpiece 2'. The article 1' comprises a body 6 similar to that described in relation to figure 1, except that in the present case the body 6 has a length of 10 mm. In addition to the body 6, the mouthpiece 2' comprises a hollow tubular element 8 and a body 4 of fibrous material. In the embodiment shown in figure 2, the article 1 ' further comprises a rod of aerosol generating material 3 connected to an upstream end 2 ' a of the mouthpiece 2 ' opposite to a downstream end 2 ' b of the mouthpiece 2 '.

Preferably, the length of body 6 is less than about 15 mm. More preferably, the length of body 6 is less than about 10 mm. In addition or alternatively, the length of body 6 is at least about 5 mm. Preferably, the length of body 6 is at least about 6 mm. In some preferred embodiments, body 6 has a length of about 5mm to about 15mm, more preferably about 6mm to about 12mm, even more preferably about 6mm to about 12mm, and most preferably about 6mm, 7mm, 8mm, 9mm, or 10 mm. In this embodiment, the length of the body 6 is 10 mm.

The pressure drop or pressure differential (also referred to as the resistance to draw) across the mouthpiece (e.g. the part of the article 1 downstream of the aerosol-generating material 3) is preferably less than about 40mmH ₂ And O. This pressure drop has been found to allow sufficient aerosol (including the desired compound such as a flavour compound) to pass through the mouthpiece 2 to the consumer. More preferably, the pressure drop across the mouthpiece 2 is less than about 32mmH ₂ And O. In some embodiments, the use has less than 31mmH ₂ O (e.g. about 29 mmH) ₂ O, about 28mmH ₂ O or about 27.5mmH ₂ O) achieves a particularly improved aerosol. Alternatively or additionally, the mouthpiece pressure drop may be at least 10mmH ₂ O, preferably at least 15mmH ₂ O, and more preferably at least 20mmH ₂ And (O). In some embodiments, the mouthpiece pressure drop may be at about 15mmH ₂ O to 40mmH ₂ And O is between. These values enable the mouthpiece 2 to slow the aerosol as it passes through the mouthpiece 2 so that the temperature of the aerosol has time to decrease before reaching the downstream end 2b of the mouthpiece 2.

The pressure drop or difference across the body is suitably 0.01mmH ₂ O to 100mmH ₂ And O is between. In some embodiments, the pressure drop across the body is less than about 50mmH ₂ O, less than about 45mmH ₂ O or less than about 30mmH ₂ O。

In the present embodiment, the body 6 is positioned downstream of, adjacent to and abutting the hollow tubular element 8, the hollow tubular element 8 also being referred to as cooling element. The hollow tubular member 8 is formed from a plurality of layers of paper which are wound in parallel with butt seams to form the tubular member 8. In this embodiment, the first paper layer and the second paper layer are provided in a two-layer tube, although in

other embodiments

3, 4 or more paper layers forming a 3, 4 or more layer tube may be used. Other configurations may be used, such as a layer of paper that is spirally wound, a cardboard tube, a tube formed using a tissue-type process, a molded or extruded plastic tube, or the like.

The hollow tubular element 8 may also be formed using a rigid plug wrap and/or tipping paper as the second plug wrap 9 and/or tipping paper 5 described herein, which means that a separate tubular element is not required. The rigid plug wrap and/or tipping paper is manufactured to have sufficient rigidity to withstand axial compression forces and bending moments that may occur during the manufacturing process and while the article 1' is in use. For example, the rigid plug wrap and/or tipping paper may have a basis weight of between 70gsm and 120gsm, more preferably between 80gsm and 110 gsm. Additionally or alternatively, the rigid plug wrap and/or tipping paper may have a thickness of between 80 μm and 200 μm, more preferably between 100 μm and 160 μm, or from 120 μm to 150 μm. It may be desirable for both the third plug wrap 11 and the tipping paper 5 to have values within these ranges to achieve an acceptable level of overall rigidity of the hollow tubular element 8.

The hollow tubular element 8 preferably has a wall thickness of at least about 100 μm and up to about 1.5mm, preferably between 100 μm and 1mm and more preferably between 150 μm and 500 μm, or about 300 μm, which can be measured, for example, using a caliper. In the present embodiment, the hollow tubular element 8 has a wall thickness of about 290 μm.

Preferably, the hollow tubular element 8 has a length of less than about 50 mm. More preferably, the hollow tubular element 8 has a length of less than about 40 mm. Still more preferably, the hollow tubular element 8 has a length of less than about 30 mm. In addition or as an alternative, the length of the hollow tubular element 8 is preferably at least about 10 mm. Preferably, the hollow tubular element 8 has a length of at least about 15 mm. In some preferred embodiments, the length of hollow tubular element 8 is from about 20mm to about 30mm, more preferably from about 22mm to about 28mm, even more preferably from about 24mm to about 26mm, most preferably about 25 mm. In this embodiment, the hollow tubular element 8 has a length of 25 mm.

The hollow tubular element 8 is located around the mouthpiece 2 and defines an air gap therein which acts as a cooling segment. The air gap provides a chamber through which the heated volatile components generated by the aerosol-generating material 3 flow. The hollow tubular element 8 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 when the article 1' is in use. The hollow tubular element 8 provides a physical displacement between the aerosol-generating material 3 and the body of material 6. The physical displacement provided by the hollow tubular element 8 will provide a thermal gradient across the length of the second hollow tubular element 8.

The hollow tubular element 8 may be configured to provide a temperature difference of at least 40 degrees celsius between the heated volatile components entering the first upstream end of the hollow tubular element 8 and the heated volatile components exiting the second downstream end of the hollow tubular element 8. The hollow tubular element 8 is preferably configured to provide a temperature difference of at least 60, 80 or preferably 100 degrees celsius between the heated volatile components entering the first upstream end of the hollow tubular element 8 and the heated volatile components exiting the second downstream end of the hollow tubular element 8. The temperature differential across the length of the hollow tubular member 8 protects the body of temperature sensitive material 6 from the high temperature of the aerosol generating material 3 as it is heated.

In an alternative article, the hollow tubular element 8 may be replaced with an alternative cooling element (e.g. an element formed from a body of material that allows the aerosol to pass longitudinally through it and also performs the function of cooling the aerosol, such as the body 6 of amorphous solid material).

In this embodiment, the body 4 of fibrous material is positioned downstream of the mouthpiece 2 ', at the mouth end 2' b, immediately downstream of and in abutting relationship with the body 6. The body 4 of fibre material is wrapped by a second plug wrap 9, which in this embodiment is identical to the first plug wrap 7. The body 6 and the body 4 of fibrous material each define a substantially cylindrical overall external shape and share a common longitudinal axis.

In this embodiment, the hollow tubular element 8, the body 6 and the body 4 of fibrous material are combined using a third plug wrap 11 which is wound around all three sections. Preferably, the third plug wrap 11 has a basis weight of less than 50gsm, more preferably between about 20gsm and 45 gsm. Preferably, the third plug wrap 11 has a thickness of between 30 μm and 60 μm, more preferably between 35 μm and 45 μm. The third plug wrap 11 is preferably a non-porous plug wrap having a permeability of less than 100Coresta units (e.g., less than 50Coresta units). However, in alternative embodiments, the third plug wrap 11 may be a porous plug wrap, for example having a permeability greater than 200Coresta units.

In the present embodiment, the body 4 of fibrous material is formed by a filamentary tow. In this embodiment, the tow used in the body 4 of fibrous material has a denier per filament (d.p.f.) of 8.4 and a total denier of 21,000. Alternatively, the tow may have a denier per filament (d.p.f.) of, for example, 9.5 and a total denier of 12,000. Alternatively, the tow may have a denier per filament (d.p.f.) of, for example, 8 and a total denier of 15,000. In this embodiment, the tow comprises plasticized cellulose acetate tow. The plasticizer used in the tow comprises about 7% by weight of the tow. In this example, the plasticizer is glyceryl triacetate. In other embodiments, different materials may be used to form the body 4 of fibrous material. For example, instead of a tow, the body 4 of fibrous material may be formed from paper, for example in a similar manner to known paper filters for cigarettes. Alternatively, the body 4 of fibrous material may be formed from a tow other than cellulose acetate (e.g. polylactic acid (PLA)), other materials described herein for filamentary tow, or the like. The tow is preferably formed of cellulose acetate. The tow, whether formed of cellulose acetate or other material, preferably has a d.p.f. of at least 5, more preferably at least 6, and even more preferably at least 7. These filament deniers provide a relatively coarse, coarse fiber tow with a lower surface area, which results in a lower pressure drop across the mouthpiece 2 compared to a tow with a lower d.p.f. value. Preferably, in order to obtain a sufficiently homogeneous body 6 of fibrous material, the tow has a denier per filament not exceeding 12d.p.f., preferably not exceeding 11d.p.f., and still more preferably not exceeding 10d.p.f.

The tow forming the body 4 of fibrous material preferably has a total denier value of at most 30,000, more preferably at most 28,000, and even more preferably at most 25,000. These total denier values provide a tow that occupies a reduced proportion of the cross-sectional area of the mouthpiece 2, which results in a lower pressure drop across the mouthpiece 2 than tows having higher total denier values. For a suitable stiffness of the body 4 of fibrous material, the tow preferably has a total denier of at least 8,000, and more preferably at least 10,000. Preferably, the denier per filament is between 5 and 12, while the total denier value is between 10,000 and 25,000. More preferably, the denier per filament is from 6 to 10, while the total denier is from 11,000 to 22,000. Preferably, the cross-sectional shape of the filaments of the tow is "Y" shaped, but in other embodiments, other shapes (such as "X" shaped filaments) having the same d.p.f. and total denier values provided herein may be used.

Preferably, the length of the body 4 of fibrous material is less than about 15 mm. More preferably, the length of the body 4 of fibrous material is less than about 10 mm. In addition or as an alternative, the length of the body 4 of fibrous material is at least about 5 mm. Preferably, the length of the body 4 of fibrous material is at least about 6 mm. In some preferred embodiments, the length of the body 4 of fibrous material is from about 5mm to about 15mm, more preferably from about 6mm to about 12mm, even more preferably from about 6mm to about 12mm, most preferably about 6mm, 7mm, 8mm, 9mm or 10 mm. In the present embodiment, the length of the body 4 of fibrous material is 10 mm.

In this embodiment, the aerosol-generating material 3 is wrapped in a wrapper 10. For example, the wrap 10 may be a paper or paper-backed foil wrap. In this embodiment, the wrap 10 is substantially air impermeable. In an alternative embodiment, the wrap 10 preferably has a permeability of less than 100Coresta units, more preferably less than 60Coresta units. It has been found that a wrapper of low permeability (e.g. having a permeability of less than 100Coresta units, more preferably less than 60Coresta units) results in an improvement of the aerosol formation in the aerosol-generating material 3. Without wishing to be bound by theory, it is hypothesized that this is due to the reduced loss of aerosol compound through the wrap 10. The permeability of the wrap 10 may be according to ISO 2965: 2009, which relates to determining the air permeability of materials used as cigarette paper, filter plug wrap, and filter-engaging paper.

In the present embodiment, the wrapper 10 includes an aluminum foil. It has been found that aluminium foil is particularly effective in enhancing aerosol formation within the aerosol-generating material 3. In this embodiment, the aluminum foil has a metal layer having a thickness of about 6 μm. In this embodiment, the aluminum foil has a paper backing. However, in alternative arrangements, the aluminium foil may have other thicknesses, for example a thickness between 4 μm and 16 μm. The aluminum foil also need not have a paper backing, but may have a backing formed of other materials, for example, to help provide the foil with adequate tensile strength, or it may not have a backing material. Metal layers or foils other than aluminum may also be used. The total thickness of the wrap is preferably between 20 μm and 60 μm, more preferably between 30 μm and 50 μm, which may provide a wrap with suitable structural integrity and heat transfer characteristics. The pulling force that may be applied to the wrapper before the wrapper breaks may be greater than 3,000 grams-force, such as between 3,000 and 10,000 grams-force or between 3,000 and 4,500 grams-force.

The article has a ventilation level of about 60% of the aerosol drawn through the article. In alternative embodiments, the article may have a ventilation level of between 50% and 80%, for example between 65% and 75%. Ventilation at these levels helps to slow the flow of aerosol drawn through the mouthpiece 2, thereby enabling the aerosol to cool sufficiently before it reaches the downstream end 2b of the mouthpiece 2. Ventilation is provided directly into the mouthpiece 2 'of the article 1'. In the present embodiment, ventilation is provided into the hollow tubular element 8, which ventilation has been found to be particularly advantageous for assisting the aerosol-generating process. Ventilation is provided via first and second parallel rows of perforations 12, formed in the present case as laser perforations, at locations 17.925mm and 18.625mm respectively from the downstream mouth end 2' b of the mouthpiece 2. These perforations pass through the tipping paper 5, the third plug wrap 11 and the hollow tubular element 8. In alternative embodiments, ventilation may be provided into the mouthpiece at other locations, for example into the fibre segment 4 or the first tubular element 11.

Aerosol-generating materials include nebulizable materials, also referred to as aerosol-forming materials. The nebulizable material may be present on a substrate. The substrate may be or comprise, for example, paper, card, paperboard, cardboard, reconstituted nebulizable material, plastic material, ceramic material, composite material, glass, metal, or metal alloy.

In the present embodiment, the aerosol-forming material added to the aerosol-generating material 3 comprises 14% by weight of the aerosol-generating material 3. Preferably, the aerosol-forming material comprises at least 5%, more preferably at least 10% by weight of aerosol-generating material. Preferably, the aerosol-forming material comprises less than 25%, more preferably less than 20%, for example between 10% and 20%, between 12% and 18% or between 13% and 16% by weight of aerosol-generating material.

Preferably, the aerosol-generating material 3 is provided as a cylindrical rod of aerosol-generating material. Regardless of the form of the aerosol-generating material, it preferably has a length of about 10mm to 100 mm. In some embodiments, the length of the aerosol-generating material is preferably in the range of about 25mm to 50mm, more preferably in the range of about 30mm to 45mm, still more preferably about 30mm to 40 mm.

The volume of the aerosol-generating material 3 provided may be from about 200mm ³ To about 4300mm ³ Preferably from about 500mm ³ To 1500mm ³ More preferably from about 1000mm ³ To about 1300mm ³ And (4) changing. It has been advantageously demonstrated that these volumes of aerosol-generating material are provided (e.g. from about 1000 mm) ³ To about 1300mm ³ ) A better aerosol is achieved with higher visibility and sensory properties than those achieved with volumes selected from the lower end of the range.

The mass of the aerosol-generating material 3 provided may be greater than 200mg, for example about 200mg to 400mg, preferably about 230mg to 360mg, more preferably about 250mg to 360 mg. It has been advantageously found that providing an aerosol generating material of higher quality results in improved organoleptic properties compared to an aerosol generated from a lower quality tobacco material.

Preferably, the aerosol-generating material 3 is formed from a tobacco material as described herein, which tobacco material comprises a tobacco component.

In the tobacco material described herein, the tobacco component preferably comprises paper reconstituted tobacco (tobacco). The tobacco component may also comprise leaf tobacco, extruded tobacco and/or bandcast tobacco.

The aerosol-generating material 3 may comprise a reconstituted tobacco material having a density of less than about 700 milligrams per cubic centimeter (mg/cc). It has been found that such tobacco materials are particularly effective in providing aerosol generating materials that can be heated rapidly to release an aerosol, as compared to more dense materials. For example, the inventors tested the properties of various aerosol-generating materials (such as tape cast reconstituted tobacco materials and paper-process reconstituted tobacco materials) upon heating. It has been found that for each given aerosol-generating material there is a particular zero heat flow temperature below which the net heat flow is endothermic, in other words more heat enters the material than leaves the material, and above which the net heat flow is exothermic, in other words more heat leaves the material than enters the material, while heat is applied to the material. Materials with densities less than 700mg/cc have lower zero heat flux temperatures. Since a large part of the heat flow out of the material is formed by the aerosol, having a lower zero heat flow temperature has a beneficial effect on the time it takes to first release the aerosol from the aerosol generating material. For example, it has been found that an aerosol-generating material having a density of less than 700mg/cc has a zero heat flow temperature of less than 164 ℃ compared to a zero heat flow temperature of greater than 164 ℃ for a material having a density of greater than 700 mg/cc.

The density of the aerosol-generating material also affects the rate of heat transfer through the material, with lower densities, e.g. densities below 700mg/cc, slower rates of heat transfer through the material and thus longer lasting aerosol release.

Preferably, the aerosol-generating material 3 comprises reconstituted tobacco material, such as a paper-making reconstituted tobacco material, having a density of less than about 700 mg/cc. More preferably, the aerosol-generating material 3 comprises reconstituted tobacco material having a density of less than about 600 mg/cc. Alternatively or additionally, the aerosol-generating material 3 preferably comprises reconstituted tobacco material having a density of at least 350mg/cc, which reconstituted tobacco material is believed to allow a sufficient amount of thermal conduction through the material.

The tobacco material may be provided in the form of cut shredded tobacco. The cut shredded tobacco may have a cut width of at least 15 cuts per inch (about 5.9 cuts/cm, corresponding to a cut width of about 1.7 mm). Preferably, the cut shredded tobacco has a cut width of at least 18 cuts per inch (about 7.1 cuts per cm, corresponding to a cut width of about 1.4 mm), more preferably at least 20 cuts per inch (about 7.9 cuts per cm, corresponding to a cut width of about 1.27 mm). In one embodiment, the cut shredded tobacco has a cut width of 22 cuts per inch (about 8.7 cuts/cm, corresponding to a cut width of about 1.15 mm). Preferably, the cut shredded tobacco has a cut width of 40 cuts/inch or less than 40 cuts/inch (about 15.7 cuts/cm, corresponding to a cut width of about 0.64 mm). It has been found that a cut width of between 0.5mm and 2.0mm, for example between 0.6mm and 1.5mm, or between 0.6mm and 1.7mm, results in a tobacco material which is preferred in terms of surface area/volume ratio (particularly when heated) and overall density and pressure drop of the material 3. The cut shredded tobacco may be formed from a mixture in the form of tobacco material, such as a mixture of one or more of paper-making reconstituted tobacco, leaf tobacco, extruded tobacco, and belt cast tobacco. Preferably, the tobacco material comprises paper-process reconstituted tobacco, or a mixture of paper-process reconstituted tobacco and leaf tobacco.

In the tobacco materials described herein, the tobacco material may contain a filler component. The filler component is typically a non-tobacco component, i.e., a component that does not contain tobacco-derived ingredients. The filler component may be a non-tobacco fibre such as wood fibre or pulp or wheat fibre. The filler component may also be an inorganic material such as chalk, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulphate, magnesium carbonate. The filler component may also be a non-tobacco cast material or a non-tobacco extruded material. The filler component may be present in an amount of 0 to 20% by weight of the tobacco material, or in an amount of 1 to 10% by weight of the composition. In some embodiments, the filler component is absent.

In the tobacco materials described herein, the tobacco material comprises an aerosol-forming material. In this case, the "aerosol-forming material" is an agent that promotes aerosol generation. The aerosol-forming material may facilitate the generation of an aerosol by promoting the initial evaporation of the gas and/or the condensation of the gas into an inhalable solid and/or liquid aerosol. In some embodiments, the aerosol-forming material may improve the delivery of flavourant from the aerosol-generating material. In general, any suitable aerosol-forming material or agent may be included in the aerosol-generating materials of the present invention, including those described herein. Other suitable aerosol-forming materials include, but are not limited to: polyols such as sorbitol, glycerol and glycols such as propylene glycol or triethylene glycol; non-polyols such as monoalcohols, high-boiling hydrocarbons, acids such as lactic acid, glycerol derivatives, esters such as diacetin, triacetin, triethylene glycol diacetate, triethyl citrate or myristate (including ethyl myristate and isopropyl myristate) and aliphatic carboxylic acid esters such as methyl stearate, dimethyl dodecanedioate and dimethyl tetradecanedioate. In some embodiments, the aerosol-forming material may be glycerol, propylene glycol, or a mixture of glycerol and propylene glycol. The glycerin may be present in an amount of 10% to 20% by weight of the tobacco material, for example 13% to 16% by weight of the composition, or 14% to 15% by weight of the composition. Propylene glycol, if present, may be present in an amount of 0.1% to 0.3% by weight of the composition.

If present, the aerosol-forming material may be included in any component of the tobacco material (e.g. any tobacco component) and/or in the filler component. Alternatively or additionally, the aerosol-forming material may be added separately to the tobacco material. In either case, the total amount of aerosol-forming material in the tobacco material may be as defined herein.

The tobacco material may comprise between 10% and 90% by weight of lamina tobacco, wherein the aerosol-forming material is provided in an amount up to about 10% by weight of the lamina tobacco. In order to achieve a total level of aerosol-forming material of between 10% and 20% by weight of the tobacco material, it has been advantageously found that this can be added to another component of the tobacco material (such as reconstituted tobacco material) at a higher weight percentage.

The tobacco material described herein contains nicotine. The nicotine content is 0.5% to 1.75% by weight of the tobacco material, and may be, for example, 0.8% to 1.5% by weight of the tobacco material. Additionally or alternatively, the tobacco material contains between 10% and 90% by weight of tobacco lamina having a nicotine content of tobacco lamina of greater than 1.5% by weight. It has been advantageously found that the use of leaf tobacco having a nicotine content of greater than 1.5% in combination with a lower nicotine base material, such as a paper process reconstituted tobacco, provides a tobacco material having a suitable nicotine level but better sensory properties than paper process reconstituted tobacco alone. The leaf tobacco (e.g., cut tobacco) can, for example, have a nicotine content of between 1.5% to 5% by weight of the leaf tobacco.

The tobacco material described herein can comprise an aerosol modifier, such as any of the flavorants described herein. In one embodiment, the tobacco material comprises menthol, thereby forming a mentholated article. The tobacco material may comprise between 3mg and 20mg menthol, preferably between 5mg and 18mg, and more preferably between 8mg and 16mg menthol. In this example, the tobacco material contained 16mg of menthol. The tobacco material may comprise between 2% and 8% by weight menthol, preferably between 3% and 7% by weight menthol, and more preferably between 4% and 5.5% by weight menthol. In one embodiment, the tobacco material comprises 4.7% by weight menthol. Such high levels of menthol loading may be achieved using a high percentage of reconstituted tobacco material (e.g., greater than 50% by weight of tobacco material). Alternatively or additionally, e.g. in using more than about 500mm ³ Or suitably greater than about 1000mm ³ In the case of aerosol-generating materials such as tobacco materials, the use of high volumes of aerosol-generating material (e.g. tobacco material) can increase the level of menthol loading that can be achieved.

In the compositions described herein, when amounts are given in% by weight, this is for the avoidance of doubt on a dry weight basis unless the contrary is specifically indicated. Thus, any water that may be present in the tobacco material or any of its components is completely ignored for the purpose of determining weight%. The moisture content of the tobacco material described herein can vary and can be, for example, from 5% to 15% by weight. The moisture content of the tobacco material described herein can vary depending on, for example, the temperature, pressure, and humidity conditions under which the composition is maintained. The water content can be determined by Karl-Fisher analysis, known to those skilled in the art. On the other hand, for the avoidance of doubt, even if the aerosol-generating material is a component in the liquid phase (such as glycerol or propylene glycol), any component other than water is included in the weight of the tobacco material. However, when the aerosol-forming material is provided in the tobacco component of a tobacco material or in the filler component (if present) of a tobacco material, the aerosol-forming material is not included in the weight of the tobacco component or filler component, but is included in the weight of the "aerosol-forming material" in weight% as defined herein, instead of or in addition to being added separately to the tobacco material. Even if of non-tobacco origin (e.g., non-tobacco fibers in the case of paper-process reconstituted tobacco), all other ingredients present in the tobacco component are included in the weight of the tobacco component.

In one embodiment, the tobacco material comprises a tobacco component as defined herein and an aerosol-forming material as defined herein. In one embodiment, the tobacco material consists essentially of a tobacco component as defined herein and an aerosol-forming material as defined herein. In one embodiment, the tobacco material consists of a tobacco component as defined herein and an aerosol-forming material as defined herein.

The papermaking process reconstituted tobacco is present in the tobacco component of the tobacco material described herein in an amount of 10% to 100% by weight of the tobacco component. In embodiments, the papermaking reconstituted tobacco is present in an amount of 10% to 80% or 20% to 70% by weight of the tobacco component. In further embodiments, the tobacco component consists essentially of or consists of paper-process reconstituted tobacco. In a preferred embodiment, the papermaking reconstituted tobacco is present in the tobacco component of the tobacco material in an amount of at least 10% by weight of the tobacco component. For example, the phyllotica may be present in an amount of at least 10% by weight of the tobacco component, with the remainder of the tobacco component comprising a paper-making reconstituted tobacco, a belt cast reconstituted tobacco, or a combination of a belt cast reconstituted tobacco and other forms of tobacco (such as tobacco particles).

The paper-making reconstituted tobacco refers to a tobacco material formed by the following method: the tobacco material is extracted with a solvent to provide an extract of soluble matter and a residue comprising fibrous material, and then the extract is recombined (typically after concentration, and optionally after further processing) with fibrous material from the residue (typically after refining of the fibrous material, and optionally adding a portion of non-tobacco fibers) by depositing the extract onto the fibrous material. The recombination process is similar to the papermaking process.

The paper-process reconstituted tobacco can be any type of paper-process reconstituted tobacco known in the art. In particular embodiments, the papermaking reconstituted tobacco is made from a feedstock comprising one or more of tobacco rod, tobacco stalk, and whole leaf tobacco. In a further embodiment, the papermaking reconstituted tobacco is made from a raw material consisting of tobacco rod and/or whole leaf tobacco and tobacco stems. However, in other embodiments, crumb (scrap), fine (fine) and winnings (winnowing) may alternatively or additionally be used in the feedstock.

The paper-process reconstituted tobacco for use in the tobacco materials described herein can be prepared by methods known to those skilled in the art for preparing paper-process reconstituted tobacco.

In this example, the article 1' has an outer perimeter of about 21mm (i.e., the article is in a semi-thin form). In other embodiments, the article may be provided in any form described herein, for example having an outer perimeter between 15mm and 25 mm. Since the article is to be heated to release the aerosol, improved heating efficiency may be achieved using articles having a lower outer perimeter in this range (e.g., a perimeter of less than 23 mm). In order to obtain an improved aerosol by heating while maintaining a suitable product length, an article circumference of greater than 19mm has also been found to be particularly effective. It has been found that articles having a circumference of between 19mm and 23mm, more preferably between 20mm and 22mm, provide a good balance between providing effective aerosol delivery while allowing effective heating.

The outer circumference of the mouthpiece 2' is substantially the same as the outer circumference of the rod of aerosol-generating material 3 so that there is a smooth transition between these components. In this embodiment, the outer circumference of the mouthpiece 2 is about 20.8 mm. The tipping paper 5 is wrapped over the entire length of the mouthpiece 2 'and covers a portion of the rod of aerosol-generating material 3 and has adhesive on its inner surface to join the mouthpiece 2' and the rod 3. In this embodiment the tipping paper 5 extends 5mm above the rod of aerosol-generating material 3, but it may alternatively extend between 3mm and 10mm, or more preferably between 4mm and 6mm, over the rod 3 in order to provide a secure attachment between the mouthpiece 2' and the rod 3. The tipping paper 5 may have a basis weight higher than the basis weight of the plug wrap used in the article 1', for example a basis weight of 40gsm to 80gsm, more preferably between 50gsm to 70gsm, and in this embodiment 58 gsm. It has been found that these basis weight ranges result in a tipping paper having acceptable tensile strength whilst being sufficiently flexible to wrap the article 1 and adhere to itself along a longitudinal lap seam on the paper. Once wrapped around the mouthpiece 2', the outer circumference of the tipping paper 5 is about 21 mm.

Figure 3 is a cross-sectional side view of another article 1 ". The article 1 "is substantially identical to the article 1' except that the mouthpiece 2" comprises a second hollow tubular element 13 at the mouth end 2 "b, instead of the body 4 of fibrous material.

The second hollow tubular element 13 is formed from a filamentary tow. It has advantageously been found that this significantly reduces the temperature of the outer surface of the mouthpiece 2 "at the downstream end 2" b of the mouthpiece which is in contact with the mouth of the consumer when the article 1 "is in use. Furthermore, it has also been found that the use of the tubular element 13 significantly reduces the temperature of the outer surface of the mouthpiece 2 ", even upstream of the tubular element 13. Without wishing to be bound by theory, it is hypothesized that this is due to the tubular element 13 guiding the aerosol closer to the centre of the mouthpiece 2 "and thus reducing the heat transfer from the aerosol to the outer surface of the mouthpiece 2".

The "wall thickness" of the second hollow tubular element 13 corresponds to the thickness of the wall of the tube 13 in the radial direction. This can be measured using calipers in the same way as the hollow tubular element 8. The wall thickness is advantageously greater than 0.9mm, and more preferably 1.0mm or greater. Preferably, the wall thickness is substantially constant around the entire wall of the second hollow tubular element 11. However, in case the wall thickness is not substantially constant, the wall thickness is preferably larger than 0.9mm, more preferably 1.0mm or more at any point around the second hollow tubular element 11.

Preferably, the length of the second hollow tubular element 13 is less than about 20 mm. More preferably, the length of the second hollow tubular element 13 is less than about 15 mm. More preferably, the length of the second hollow tubular element 13 is less than about 10 mm. Additionally or alternatively, the second hollow tubular element 13 has a length of at least about 5 mm. Preferably, the length of the second hollow tubular element 13 is at least about 6 mm. In some preferred embodiments, the second hollow tubular element 13 has a length of about 5mm to about 20mm, more preferably about 6mm to about 10mm, even more preferably about 6mm to about 8mm, most preferably about 6mm, 7mm or about 8 mm. In this embodiment, the second hollow tubular element 13 has a length of 6 mm.

Preferably, the second hollow tubular member 13 has a density of at least about 0.25g/cm ³ (g/cc), more preferably at least about 0.3 g/cc. Preferably, the density of the second hollow tubular member 13 is less than about 0.75g/cm ³ (g/cc), more preferably less than 0.6 g/cc. In some embodiments, the second hollow tubular member 13 has a density of between 0.25 and 0.75g/cc, more preferably between 0.3 and 0.6g/cc, and more preferably between 0.4g/cc and 0.6g/cc or about 0.5 g/cc. These densities have been found to provide a good balance between the improved hardness provided by the denser material and the lower heat transfer characteristics of the less dense material. For the purposes of the present invention, the "density" of the hollow tubular member 13 refers to the density of the filamentary tow forming the member with any plasticizer incorporated therein. The density of the second hollow tubular element 13 can be determined in the same way as described for the body 6.

The filamentary tow forming the second hollow tubular member 13 preferably has a total denier of less than 45,000, more preferably less than 42,000. This total denier has been found to allow the formation of less dense tubular elements 13. Preferably, the total denier is at least 20,000, more preferably at least 25,000. In a preferred embodiment, the filamentous tow forming the hollow tubular element 13 has a total denier of between 25,000 and 45,000, more preferably between 35,000 and 45,000. Preferably, the cross-sectional shape of the filaments of the tow is "Y" shaped, although in other embodiments, other shapes (such as "X" shaped filaments) may be used.

The filamentary tow forming the second hollow tubular member 13 preferably has a denier per filament of greater than 3. It has been found that such a monofilament denier allows the formation of a less dense tubular element 13. Preferably, the filament denier is at least 4, more preferably at least 5. In a preferred embodiment, the filamentary tow forming the second hollow tubular element 13 has a denier per filament between 4 and 10, more preferably between 4 and 9. In one embodiment, the filamentary tow forming the second hollow tubular member 13 has an 8Y40,000 tow formed of cellulose acetate and including 18% plasticizer (e.g., triacetin).

The second hollow tubular element 13 preferably has an inner diameter greater than 3.0 mm. A smaller diameter than this may result in the velocity of the aerosol through the mouthpiece 2 to the consumer's mouth increasing more than desired so that the aerosol becomes too hot, for example to reach a temperature of greater than 40 ℃ or greater than 45 ℃. More preferably, the second hollow tubular element 13 has an internal diameter greater than 3.1mm, and still more preferably greater than 3.5mm or 3.6 mm. In one embodiment, the inner diameter of the second hollow tubular element 13 is about 3.9 mm.

The second hollow tubular element 13 preferably comprises 15 to 22% by weight of a plasticizer. For cellulose acetate tow, the plasticizer is preferably triacetin, although other plasticizers (such as polyethylene glycol (PEG)) may be used. More preferably, the tubular element 13 comprises 16% to 20% by weight of plasticizer, for example about 17%, about 18% or about 19% plasticizer.

The combination of the aerosol cooling effect of the hollow tubular member 8 and body 6 together with the aerosol cooling effect of the second hollow tubular member 13 providing a reduced temperature of the outer surface of the mouthpiece results in a more comfortable user experience as the aerosol temperature and the temperature of the outer surface of the article at the mouth end is reduced.

Fig. 4 is a cross-sectional side view of another article 1 "'. The article 1 "' and mouthpiece 2" ' are substantially identical to the article 1 ' and mouthpiece 2 ' except that a body 6 of amorphous solid material is provided at the distal end of the mouthpiece 2 "' adjacent to and in abutting relationship with the aerosol generating material 3, and a hollow tubular element 8 is provided downstream of the body 6, positioned between the body 6 at the distal end of the mouthpiece and the fibre segment 4 at the mouth end of the mouthpiece.

Providing a body 6 of amorphous solid material adjacent to the aerosol-generating material results in the body 6 being subjected to greater heating than when the body 6 is positioned downstream of the cooling element. When the amorphous solid material comprises a flavourant, the result of this arrangement may be improved release of flavourant from the amorphous solid material.

Figure 5a is a side cross-sectional view of another article 1 "" comprising a mouthpiece 2 "" containing a capsule. Figure 5b is a cross-sectional view of the mouthpiece shown in figure 5a containing a capsule. The article 1 "" and mouthpiece 2 "" are identical to the article 1 'and mouthpiece 2', except that the mouthpiece 2 "" comprises a capsule housing section 14, in addition to the hollow tubular member 8, the body of amorphous solid material 6 and the body of fibrous material 4. The capsule housing section 14 includes an aerosol modifier provided in the form of a capsule 15 and is surrounded by an oil resistant plug wrap 16.

In other embodiments, the aerosol-modifying agent may be in other forms, such as a material impregnated into the body of fibrous material 4 or disposed on threads (e.g., threads carrying a flavorant or other aerosol-modifying agent), and may also be disposed within the body of fibrous material 4. The amorphous solid material forming body 6 may also contain aerosol modifiers such as flavourants. When the amorphous solid material comprises a flavorant, the aerosol-modifying agent contained within the capsule 15 may be selected to be complementary to the flavorant contained in the amorphous solid material.

Capsule 15 may comprise a breakable capsule, such as a capsule having a solid, frangible shell surrounding a liquid payload. In the present embodiment, a single capsule 15 is used. The capsule 15 is completely embedded in the body of material, which is substantially identical to the body of fibrous material 4. In other words, the capsule 15 is completely surrounded by the material of the forming body 14. In other embodiments, a plurality of breakable capsules may be disposed within the body 6 of material 14, such as 2, 3, or more breakable capsules. The length of the body of material 14 may be increased to accommodate the number of capsules required. In embodiments where multiple capsules are used, the individual capsules may be identical to one another, or may differ from one another in size and/or capsule payload. In other embodiments, multiple volumes of material 14 may be provided, wherein each volume contains one or more capsules.

The capsule 15 has a core-shell structure. In other words, capsule 15 includes a shell that encloses a liquid agent (e.g., a flavoring agent or other agent), which may be any of the flavoring agents or aerosol modifiers described herein. The shell of the capsule can be ruptured by the user to release the flavoring or other agent into the body 14 of material. The oil resistant plug wrap 16 may include a barrier coating to render the material of the plug wrap substantially impermeable to the liquid payload of the capsule 15. Alternatively or in addition, the second plug wrap 9 and/or tipping paper 5 may comprise a barrier coating to render the material of the plug wrap and/or tipping paper substantially impermeable to the liquid payload of the capsule 15.

In the present embodiment, the capsule 15 is spherical and has a diameter of about 3 mm. In other embodiments, other shapes and sizes of capsules may be used. The total weight of the capsule 15 may range from about 10mg to about 50 mg.

In this embodiment, the capsule 15 is located at a longitudinally central location within the body of the material 14. That is, the capsule 15 is positioned such that its center is 4mm from each end of the body of material 14. In other embodiments, the capsule 15 may be located in the body of material 14 at a location other than the longitudinally central location, i.e., closer to the downstream end of the body of material 14 than the upstream end, or closer to the upstream end of the body of material 14 than the downstream end. Preferably, the mouthpiece 2 "" is configured such that the capsule 15 and the vent 12 are longitudinally offset from each other in the mouthpiece 2 "".

The cross section of the mouthpiece 2 "" is shown in figure 5 b. Figure 5b shows the capsule 15, the body of material 14, the oil resistant plug wrap 16, the third plug wrap 11, and the tipping paper 5. In this example, the capsule 15 is centered on the longitudinal axis (not shown) of the mouthpiece 2 "". The oil resistant plug wrap 16, the third plug wrap 11 and the tipping paper 5 are arranged concentrically around the body 14 of material.

The breakable capsules 15 have a core-shell structure. That is, the encapsulating or barrier material creates a shell around the core containing the aerosol modifier. The shell structure hinders migration of the aerosol modifier during storage of the article 1 ""', but allows for controlled release of the aerosol modifier (also referred to as aerosol modifier) during use.

In some cases, the barrier material (also referred to herein as an encapsulant material) is frangible. The capsule is crushed or otherwise ruptured or ruptured by the user to release the encapsulated aerosol modifying agent. Typically, the capsule is ruptured immediately before heating begins, but the user may select when to release the aerosol modifying agent. The term "breakable capsule" refers to a capsule in which a shell can be broken by pressure to release a core; more precisely, when the user wants to release the core of the capsule, the shell can be ruptured under the pressure exerted by the user's finger.

In some cases, the barrier material is heat resistant. That is, in some cases, the barrier does not rupture, melt, or otherwise fail at the temperature of reaching the capsule site during operation of the aerosol provision device. Illustratively, the capsule located in the mouthpiece may be exposed to a temperature in the range of, for example, 30 ℃ to 100 ℃, and the barrier material may continue to retain the liquid core until at least about 50 ℃ to 120 ℃.

In other cases, the capsules release the core composition upon heating, for example, by melting the barrier material or by swelling of the capsules that causes rupture of the barrier material.

The total weight of the capsule may be in the range of about 1mg to about 100mg, suitably about 5mg to about 60mg, about 8mg to about 50mg, about 10mg to about 20mg, or about 12mg to about 18 mg.

The total weight of the core formulation (core formulation) may be in the range of about 2mg to about 90mg, suitably about 3mg to about 70mg, about 5mg to about 25mg, about 8mg to about 20mg, or about 10mg to about 15 mg.

The capsule according to the invention comprises a core and a shell as described above. The capsules may have a crush strength of from about 4.5N to about 40N, more preferably from about 5N to about 30N or to about 28N (e.g., from about 9.8N to about 24.5N). The capsule burst strength can be measured when the capsule is removed from the body of material 14, and the force with which the capsule bursts when pressed between two flat metal plates is measured using a load cell. A suitable measuring device is a Sauter FK 50 dynamometer with a flat head attachment, which can be used to crush the capsule against a flat, hard surface having a surface similar to the attachment.

The capsule may be substantially spherical and have a diameter of at least about 0.4mm, 0.6mm, 0.8mm, 1.0mm, 2.0mm, 2.5mm, 2.8mm or 3.0 mm. The capsule may have a diameter of less than about 10.0mm, 8.0mm, 7.0mm, 6.0mm, 5.5mm, 5.0mm, 4.5mm, 4.0mm, 3.5mm, or 3.2 mm. Illustratively, the capsule diameter may be in the range of about 0.4mm to about 10.0mm, about 0.8mm to about 6.0mm, about 2.5mm to about 5.5mm, or about 2.8mm to about 3.2 mm. In some cases, the capsule may have a diameter of about 3.0 mm. These dimensions are particularly suitable for incorporating the capsules into an article as described herein.

In some embodiments, the cross-sectional area of the capsule 15 at its largest cross-sectional area is less than 28%, more preferably less than 27%, and still more preferably less than 25% of the cross-sectional area of the portion of the mouthpiece 2' where the capsule 15 is provided. For example, for a spherical capsule having a diameter of 3.0mm, the maximum cross-sectional area of the capsule is 7.07mm ² . For a mouthpiece 2 "" having a circumference of 21mm as described herein, the body 14 of material has an outer circumference of 20.8mm and the radius of the component would be 3.31mm, corresponding to 34.43mm ² Cross-sectional area of. In this example, the cross-sectional area of the capsule is 20.5% of the cross-sectional area of the mouthpiece 2 "". As another example, if the capsule has a diameter of 3.2mm, its maximum cross-sectional area is 8.04mm ² . In this case, the cross-sectional area of the capsule will be material23.4% of the cross-sectional area of body 14. Capsules having a maximum cross-sectional area of less than 28% of the cross-sectional area of the portion of the mouthpiece 2 "", where the capsule 11 is located, have the advantage that: the mouthpiece 2 "" has a reduced pressure drop compared to a capsule of larger cross-sectional area, and leaves sufficient space around the capsule for the aerosol to pass through without the body of material 14 removing a significant amount of the aerosol as it passes through the mouthpiece 2 "".

Preferably, the reduction in pressure drop or differential pressure (also referred to as resistance to draw) across the article, measured as open pressure drop (i.e., vent opening) when the capsule is ruptured is less than 8mmH ₂ And O. More preferably, the reduction in open pressure drop is less than 6mmH ₂ O, and more preferably less than 5mmH ₂ And O. These values are measured as the average achieved by at least 80 articles made to the same design. This small variation in pressure drop means that other aspects of the product design, such as setting the correct level of ventilation for a given product pressure drop, can be achieved whether or not the consumer chooses to rupture the capsule.

In some embodiments, when the aerosol-generating material 3 is heated to provide an aerosol, for example within the non-combustible aerosol providing device described herein, the portion of the mouthpiece 2 in which the capsule is located reaches a temperature of between 58 degrees celsius and 70 degrees celsius during aerosol generation using the system. Due to this temperature, the capsule contents are heated sufficiently to promote volatilization of the capsule contents (e.g., aerosol modifier) into the aerosol formed by the system as the aerosol passes through the mouthpiece 2'. For example, the contents of the capsule 15 may be heated prior to the capsule 15 rupturing, such that when the capsule 15 ruptures, its contents are more readily released into the aerosol passing through the mouthpiece 2 "". Alternatively, after the capsule 15 is ruptured, the contents of the capsule 15 may be heated to this temperature, again resulting in an increased release of the contents into the aerosol. Advantageously, it has been found that the mouthpiece temperature is in the range of 58 to 70 degrees celsius high enough that the capsule contents can be more easily released, but low enough that the outer surface of the portion of the mouthpiece 2 "" where the capsule is located does not reach an uncomfortable temperature that the consumer contacts in order to rupture the capsule 15 by squeezing on the mouthpiece 2 "".

The capsule 15 may be ruptured by an external force applied to the mouthpiece 2 "", such as by a consumer squeezing the mouthpiece 2 "", using their finger or other mechanism. As described above, the portion of the mouthpiece located in the capsule is arranged to reach a temperature of greater than 58 ℃ during use of the aerosol provision system to generate an aerosol. Preferably, the burst strength of the capsule 15 is between 1500 and 4000 gram-force when the capsule 15 is positioned within the mouthpiece 2 "", and prior to heating the aerosol-generating material 3. Preferably, the burst strength of the capsule 15 is between 1000 grams force and 4000 grams force when the capsule 15 is positioned within the mouthpiece 2 "", and within 30 seconds of generating an aerosol using the aerosol provision system. Thus, although the capsule 15 is subjected to temperatures above 58 ℃ (e.g., between 58 ℃ and 70 ℃), the capsule is able to maintain burst strength within a range that has been found to enable the capsule 15 to be easily crushed by a consumer, while providing the consumer with sufficient tactile feedback that the capsule 15 has been breached. Maintaining such burst strength is achieved by selecting an appropriate gelling agent (such as a polysaccharide, including, for example, gum arabic, gellan gum, acacia gum, xanthan gum, or carrageenan) for the capsule as described herein, alone or in combination with gelatin. Furthermore, a suitable wall thickness for the capsule housing should be selected.

Suitably, the burst strength of the capsule is between 2000 grams force and 3500 grams force, or between 2500 grams force and 3500 grams force, when the capsule is positioned within the mouthpiece and prior to heating the aerosol generating material. Suitably, the burst strength of the capsule is between 1500 to 4000 grams force, or between 1750 to 3000 grams force, when the capsule is located within the mouthpiece and within 30s of generating an aerosol using the system. In one embodiment, the average burst strength of the capsule is about 3175 grams force when the capsule is positioned within the mouthpiece and prior to heating the aerosol-generating material, and the average burst strength of the capsule is about 2345 grams force when the capsule is positioned within the mouthpiece and within 30 seconds of generating an aerosol using the system.

The rupture strength of the capsule can be tested using a force measuring instrument, such as a texture analyzer.

The barrier material may include one or more of a gelling agent, a bulking agent, a buffer, a coloring agent (coloring agent), and a plasticizer.

Suitably, the gelling agent may be, for example, a polysaccharide or cellulose gelling agent, a gelatin, a gum, a gel, a wax, or a mixture thereof. Suitable polysaccharides include alginates, dextrans, maltodextrins, cyclodextrins, and pectins. Suitable alginates include, for example, alginate, esterified alginate or glyceryl alginate. Alginates include ammonium alginate, triethanolamine alginate, and group I or II metal ion alginates (such as sodium alginate, potassium alginate, calcium alginate, and magnesium alginate). Esterified alginates include propylene glycol alginate and glyceryl alginate. In an embodiment, the barrier material is sodium alginate and/or calcium alginate. Suitable cellulosic materials include methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose, cellulose acetate, and cellulose ethers. The gelling agent may comprise one or more modified starches. The gelling agent may comprise carrageenan. Suitable gums include agar, gellan (gellan gum), gum arabic, pullulan (pullan gum), mannan gum, gum ghatti (gum ghatti), tragacanth gum, Karaya gum (Karaya), locust bean gum, acacia gum (acacia gum), guar gum, quince seed, and xanthan gum. Suitable gels include agar, agarose, carrageenan, fucoidan, and furcellaran. Suitable waxes include carnauba wax. In some cases, the gelling agent may comprise carrageenan and/or gellan gum; the gelling agent is particularly suitable to be included as gelling agent, since the pressure required to rupture the resulting capsule is particularly suitable.

The barrier material may include one or more bulking agents such as starches, modified starches (such as oxidized starches) and sugar alcohols (such as maltitol).

The barrier material may comprise a colorant which makes it easier to position the capsule within the aerosol-generating device during manufacture of the aerosol-generating device. The colorant is preferably selected from the group consisting of a colorant (colorant) and a pigment.

The barrier material may also comprise at least one buffer (such as a citrate or phosphate compound).

The barrier material may also comprise at least one plasticizer which may be glycerol, sorbitol, maltitol, glyceryl triacetate, polyethylene glycol, propylene glycol or another polyol having plasticizing properties, and optionally one acid of the monobasic, dibasic or tribasic type (in particular citric acid, fumaric acid, malic acid, etc.). The amount of plasticizer ranges between 1% to 30% by weight, preferably between 2% to 15% by weight, even more preferably between 3% to 10% by weight of the total dry weight of the shell.

The barrier material may also comprise one or more filler materials. Suitable filler materials include starch derivatives such as dextrin, maltodextrin, cyclodextrin (alpha, beta or gamma), or cellulose derivatives such as hydroxypropyl methylcellulose (HPMC), hydroxypropyl cellulose (HPC), Methylcellulose (MC), carboxymethyl cellulose (CMC), polyvinyl alcohol, polyols or mixtures thereof. Dextrin is a preferred filler. The amount of filler in the shell is at most 98.5%, preferably from 25% to 95%, more preferably from 40% to 80%, and even more preferably from 50% to 60% by weight of the total dry weight of the shell.

The capsule shell may additionally comprise a hydrophobic outer layer which reduces the susceptibility of the capsule to moisture-induced degradation. The hydrophobic outer layer is suitably selected from the group comprising: waxes, especially carnauba wax, candelilla wax or beeswax, carbowax, shellac (in alcohol or aqueous solution), ethyl cellulose, hydroxypropyl methyl cellulose, hydroxypropyl cellulose, emulsion compositions, polyvinyl alcohol, or combinations thereof. More preferably, the at least one moisture barrier is ethyl cellulose or a mixture of ethyl cellulose and shellac.

The capsule core comprises an aerosol modifier. Such an aerosol modifier may be any volatile substance that alters at least one characteristic of the aerosol. For example, the aerosol substance may alter pH, sensory characteristics, moisture content, delivery characteristics, or flavor. In some cases, the aerosol modifier may be selected from an acid, a base, water, or a fragrance. In some embodiments, the aerosol modifier comprises one or more flavorants.

The flavouring agent may suitably be licorice, rose oil, vanilla, lemon oil, orange oil, mint flavour, suitably menthol and/or mint oil from any species of the genus mentha (such as peppermint and/or spearmint oil, or lavender, anise or anise).

In some cases, the flavoring agent comprises menthol.

In some cases, the capsule may comprise at least about 25% w/w of flavorant (based on the total weight of the capsule), suitably at least about 30% w/w of flavorant, 35% w/w of flavorant, 40% w/w of flavorant, 45% w/w of flavorant, or 50% w/w of flavorant.

In some cases, the core may comprise at least about 25% w/w flavourant (based on the total weight of the core), suitably at least about 30% w/w flavourant, 35% w/w flavourant, 40% w/w flavourant, 45% w/w flavourant, or 50% w/w flavourant. In some cases, the core may comprise less than or equal to about 75% w/w flavorant (based on the total weight of the core), suitably less than or equal to about 65% w/w flavorant, 55% w/w flavorant, or 50% w/w flavorant. Illustratively, the capsules may comprise flavoring in an amount ranging from 25 to 75% w/w (based on the total weight of the core), from about 35 to 60% w/w, or from about 40 to 55% w/w.

The capsule may contain at least about 2mg, 3mg or 4mg of aerosol modifier, suitably at least about 4.5mg of aerosol modifier, 5mg of aerosol modifier, 5.5mg of aerosol modifier or 6mg of aerosol modifier.

The core may also contain a solvent that dissolves the aerosol modifier.

Any suitable solvent may be used.

When the aerosol-modifying agent comprises a flavourant, the solvent may suitably comprise short or medium chain fats and oils. For example, the solvent may include a triglyceride of glycerol (such as C) ₂ -C ₁₂ Triglycerides, suitably C ₆ -C ₁₀ Triglycerides or C ₅ -C ₁₂ Triglycerides). For example, the solvent can include medium chain triglycerides (MCT-C) ₈ -C ₁₂ ) It may be derived from palm oil and/or coconut oil.

Esters may be formed with caprylic and/or capric acid. For example, the solvent may include a medium chain triglyceride that is caprylic acid triglyceride and/or capric acid triglyceride. For example, the solvent may include a compound identified by numbers 73398-61-5, 65381-09-1, 85409-09-2 in the CAS registry. Such medium chain triglycerides are odorless and tasteless.

The Hydrophilic Lipophilic Balance (HLB) of the solvent may be in the range of 9 to 13, suitably 10 to 12. The process for preparing the capsules comprises co-extrusion, optionally followed by centrifugation and solidification and/or drying. The contents of WO 2007/010407a2 are incorporated by reference in their entirety.

In alternative embodiments, the

mouthpieces

2, 2 ', 2 "', and 2" ", may each be formed from any combination of mouthpiece components described herein.

A non-flammable aerosol providing apparatus is used to heat an aerosol generating material 3 of the

articles

1, 1 ', 1 "', 1" ", described herein. The non-flammable aerosol providing device preferably comprises a coil, as this has been found to enable improved heat transfer to the

article

1, 1 ', 1 "', 1" ", compared to other arrangements.

In some embodiments, the coil is configured to cause, in use, heating of the at least one electrically conductive heating element such that thermal energy may be conducted from the at least one electrically conductive heating element to the aerosol-generating material to thereby cause heating of the aerosol-generating material.

In some embodiments, the coil is configured to generate, in use, a varying magnetic field for penetrating the at least one heating element to thereby cause inductive heating and/or hysteresis heating of the at least one heating element. In such an arrangement, the or each heating element may be referred to as a "susceptor" as defined herein. A coil configured to generate, in use, a varying magnetic field for penetrating the at least one electrically conductive heating element to thereby cause inductive heating of the at least one electrically conductive heating element may be referred to as an "induction coil" or "induction coil".

The device may comprise a heating element, for example an electrically conductive heating element, and the heating element may be suitably positioned or positionable relative to the coil to effect such heating of the heating element. The heating element may be in a fixed position relative to the coil. Alternatively, at least one heating element (e.g. at least one electrically conductive heating element) may be included in the article 1, 1 'for insertion into a heating zone of the device, wherein the article 1, 1' further comprises aerosol-generating material 3 and is removable from the heating zone after use. Alternatively, both the apparatus and such an article 1, 1' may comprise at least one corresponding heating element, e.g. at least one electrically conductive heating element, and the coil may be used to cause heating of the heating element of each of the apparatus and the article when the article is in the heating zone.

In some embodiments, the coil is helical. In some embodiments, the coil surrounds at least a portion of a heating zone of a device configured to receive aerosol-generating material. In some embodiments, the coil is a helical coil that encircles at least a portion of the heating zone.

In some embodiments, the device comprises an electrically conductive heating element at least partially surrounding the heating region, and the coil is a helical coil surrounding at least a portion of the electrically conductive heating element. In some embodiments, the electrically conductive heating element is tubular. In some embodiments, the coil is an inductive coil.

In some embodiments, the use of coils enables the non-combustible aerosol provision apparatus to reach operating temperatures faster than non-coil aerosol provision apparatus. For example, a non-combustible aerosol provision device comprising a coil as described above may reach an operating temperature such that a first puff may be provided in less than 30 seconds, more preferably in less than 25 seconds, from the start of the device heating procedure. In some embodiments, the device may reach the operating temperature within about 20 seconds from the beginning of the device heating program.

It has been found that the use of a coil as described herein in a device to cause heating of the aerosol generating material enhances the aerosol produced. For example, consumers report that aerosols generated by devices including coils such as described herein are organoleptically closer to aerosols generated in factory-made cigarette (FMC) products than aerosols generated by other non-combustible aerosol provision systems. Without wishing to be bound by theory, it is hypothesized that this is a result of the reduced time to reach the desired heating temperature when using the coil, the higher heating temperature achievable when using the coil, and/or the coil enabling such systems to simultaneously heat a relatively large volume of aerosol-generating material, producing an aerosol temperature similar to the FMC aerosol temperature. In FMC products, the burning coal generates a hot aerosol that heats the tobacco in the tobacco rod behind the coal as the aerosol is drawn through the rod. The hot aerosol is understood to release the flavour compound from the tobacco in the rod behind the burning coal. Devices comprising coils as described herein are believed to be also capable of heating aerosol generating materials (such as tobacco materials as described herein) to release a flavour compound, thereby producing an aerosol which has been reported to more closely resemble an FMC aerosol.

With an aerosol-providing system comprising a coil as described herein (e.g. an induction coil that heats at least some of the aerosol-generating material to at least 200 ℃, more preferably at least 220 ℃) may enable the generation of an aerosol from an aerosol-generating material having specific properties that are believed to be more closely similar to those of an FMC product. For example, when an inductive heater heated to at least 250 ℃ is used to heat an aerosol-generating material comprising nicotine for a period of two seconds, at an airflow of at least 1.50L/m during this period, one or more of the following characteristics have been observed:

at least 10 μ g of nicotine is aerosolized from the aerosol-generating material;

the weight ratio of aerosol-forming material to nicotine in the aerosol produced is at least about 2.5:1, suitably at least 8.5: 1;

at least 100 μ g of aerosol-forming material may be atomised from the aerosol-generating material;

an average particle or droplet size in the generated aerosol of less than about 1000 nm; and

the aerosol density is at least 0.1 μ g/cc.

In some cases, during this period of time, at least 10 μ g of nicotine, suitably at least 30 μ g or 40 μ g of nicotine, is aerosolized from the aerosol-generating material under an airflow of at least 1.50L/m. In some cases, less than about 200 μ g, suitably less than about 150 μ g, or less than about 125 μ g of nicotine is present under an airflow of at least 1.50L/m during this period of time.

In some cases, the aerosol comprises at least 100 μ g of aerosol-forming material, suitably at least 200 μ g, 500 μ g or 1mg of aerosol-forming material is atomised from the aerosol-generating material under a gas flow of at least 1.50L/m during this period. Suitably, the aerosol-forming material may comprise or consist of glycerol.

As defined herein, the term "average particle size or droplet size" refers to the average size of the solid or liquid component of an aerosol (i.e., the component suspended in a gas). When an aerosol comprises suspended liquid droplets and suspended solid particles, the term refers to the average size of all components together.

In some cases, the average particle or droplet size in the generated aerosol may be less than about 900nm, 800nm, 700nm, 600nm, 500nm, 450nm, or 400 nm. In some cases, the average particle size or droplet size may be greater than about 25nm, 50nm, or 100 nm.

In some cases, the generated aerosol density is at least 0.1 μ g/cc during the time period. In some cases, the aerosol density is at least 0.2 μ g/cc, 0.3 μ g/cc, or 0.4 μ g/cc. In some cases, the aerosol density is less than about 2.5 μ g/cc, 2.0 μ g/cc, 1.5 μ g/cc, or 1.0 μ g/cc.

The non-combustible aerosol provision device is preferably arranged to heat the aerosol-generating material 3 of the

article

1, 1', 1 "to a maximum temperature of at least 160 ℃. Preferably, the non-combustible aerosol provision device is arranged to heat the aerosol-forming material 3 of the

article

1, 1', 1 "at least once to a maximum temperature of at least about 200 ℃, or at least about 220 ℃, or at least about 240 ℃, more preferably at least about 270 ℃ during a heating process subsequent to the non-combustible aerosol provision device.

Using an aerosol provision system comprising a coil as described herein (e.g. an induction coil that heats at least some of the aerosol generating material to at least 200 ℃, more preferably at least 220 ℃) may enable the generation of an aerosol from the aerosol generating material in an

article

1, 1 ', 1 "', 1" ", as described herein, which article has a higher temperature than previous devices as the aerosol leaves the mouth end of the

mouthpiece

2, 2 ', 2"', 2 "", thereby facilitating the generation of an aerosol which is believed to be closer to the FMC product. For example, the highest aerosol temperature measured at the mouth end of the

article

1, 1 ', 1 "', 1" ", may preferably be greater than 50 ℃, more preferably greater than 55 ℃ and still more preferably greater than 56 ℃ or 57 ℃. Additionally or alternatively, the maximum aerosol temperature measured at the mouth end of the

article

1, 1 ', 1 "', 1" ", may be less than 62 ℃, more preferably less than 60 ℃ and more preferably less than 59 ℃. In some embodiments, the maximum aerosol temperature measured at the mouth end of the

article

1, 1 ', 1 "', 1" ", may preferably be between 50 ℃ and 62 ℃, more preferably between 56 ℃ and 60 ℃.

Fig. 6 shows an embodiment of a non-combustible aerosol provision apparatus 100 for generating an aerosol from an aerosol generating medium/material (aerosol generating material 3 of an

article

1, 1 ', 1 "', 1" ") as described herein. In a broad sense, the apparatus 100 may be used to heat a replaceable article 110 containing an aerosol-generating medium, such as the

articles

1, 1 ', 1 "', 1" ", described herein, to generate an aerosol or other inhalable medium to be inhaled by a user of the apparatus 100. Together, the apparatus 100 and the replaceable article 110 form a system.

The device 100 includes a housing 102 (in the form of an enclosure) that surrounds and contains the various components of the device 100. The apparatus 100 has an opening 104 at one end through which an article 110 may be inserted for heating by the heating assembly. In use, the article 110 may be fully or partially inserted into a heating assembly, where it may be heated by one or more components of the heater assembly.

The apparatus 100 of this embodiment includes a first end member 106 including a cover 108 that is movable relative to the first end member 106 to close the opening 104 when no article 110 is in place. In fig. 6, the cover 108 is shown in an open configuration, however the cover 108 may be moved into a closed configuration. For example, the user may slide the cover 108 in the direction of arrow "B".

The device 100 may also include a user-operable control element 112, such as a button or switch, which when pressed operates the device 100. For example, a user may turn on the device 100 by operating the switch 112.

Device 100 may also include electrical components (such as a socket/port 114) that may receive a cable to charge a battery of device 100. For example, the receptacle 114 may be a charging port, such as a USB charging port.

Fig. 7 shows the device 100 of fig. 6 with the housing 102 removed and no article 110 present. The apparatus 100 defines a longitudinal axis 134. As shown in fig. 7, the first end member 106 is disposed at one end of the apparatus 100 and the second end member 116 is disposed at an opposite end of the apparatus 100. Together, the first end member 106 and the second end member 116 at least partially define an end surface of the apparatus 100. For example, a bottom surface of the second end member 116 at least partially defines a bottom surface of the device 100. The edges of the housing 102 may also define a portion of the end surface. In this embodiment, the cover 108 also defines a portion of the top surface of the device 100.

The end of the device closest to the opening 104 may be referred to as the proximal end (or mouth end) of the device 100, since it is closest to the user's mouth when in use. In use, a user inserts the article 110 into the opening 104, operates the user controls 112 to begin heating the aerosol-generating material and drawing an aerosol generated in the apparatus. This causes the aerosol to flow through the device 100 along a flow path towards the proximal end of the device 100.

The other end of the device furthest from the mouth 104 may be referred to as the distal end of the device 100, as it is the end furthest from the mouth of the user when in use. As the user draws aerosol generated in the device, the aerosol flows away from the distal end of the device 100.

The device 100 also includes a power supply 118. The power source 118 may be, for example, a battery (such as a rechargeable battery or a non-rechargeable battery). Examples of suitable batteries include, for example, lithium batteries (such as lithium ion batteries), nickel batteries (such as nickel-cadmium batteries), and alkaline batteries. The battery is electrically coupled to the heating assembly to supply power to heat the aerosol generating material when required and under the control of a controller (not shown). In this embodiment, the batteries are connected to a central support 120 that holds the batteries 118 in place.

The device further comprises at least one electronic module 122. The electronic module 122 may include, for example, a Printed Circuit Board (PCB). The PCB 122 may support at least one controller (such as a processor and memory). PCB 122 may also include one or more electrical traces for electrically connecting together the different electronic components of device 100. For example, the battery terminals may be electrically connected to the PCB 122 so that power may be distributed throughout the device 100. The receptacle 114 may also be electrically coupled to a battery via electrical tracks.

In the exemplary apparatus 100, the heating assembly is an inductive heating assembly and includes various components that heat the aerosol-generating material of the article 110 via an inductive heating process. Induction heating is the process of heating an electrically conductive object, such as a susceptor, by electromagnetic induction. The induction heating assembly may include an inductive element (e.g., one or more induction coils) and a device for passing a varying current (such as an alternating current) through the inductive element. The varying current in the inductive element generates a varying magnetic field. The varying magnetic field penetrates a susceptor, which is suitably positioned with respect to the inductive element, and generates eddy currents inside the susceptor. The susceptor has an electrical resistance to eddy currents and thus the flow of eddy currents to this resistance causes the susceptor to heat by joule heating. In case the susceptor comprises a ferromagnetic material, such as iron, nickel or cobalt, heat may also be generated by hysteresis losses in the susceptor, i.e. a varying orientation of the magnetic dipoles in the magnetic material due to their alignment with a varying magnetic field. In induction heating, heat is generated inside the susceptor, allowing for rapid heating, as compared to heating, for example, by conduction. Furthermore, no physical contact between the induction heater and the susceptor is required, allowing for an increased degree of freedom in construction and application.

The induction heating assembly of the example apparatus 100 includes a susceptor arrangement 132 (referred to herein as a "susceptor"), a first induction coil 124, and a second induction coil 126. The first and

second inductors

124, 126 are made of a conductive material. In this embodiment, the first and

second inductors

124, 126 are made of litz wire/cable that is wound in a spiral fashion to provide

spiral inductors

124, 126. Litz wire comprises a plurality of individual wires that are individually insulated and twisted together to form a single wire. Litz wire is designed to reduce skin effect losses in the conductor. In the exemplary apparatus 100, the first inductor winding 124 and the second inductor winding 126 are made of copper litz wire having a rectangular cross section. In other embodiments, the litz wire may have other shapes in cross-section (such as circular).

The first inductor coil 124 is configured to generate a first varying magnetic field for heating a first section of the susceptor 132, and the second inductor coil 126 is configured to generate a second varying magnetic field for heating a second section of the susceptor 132. In this embodiment, first inductive coil 124 is adjacent to second inductive coil 126 in a direction along longitudinal axis 134 of apparatus 100 (i.e., first and second

inductive coils

124, 126 do not overlap). The susceptor arrangement 132 may comprise a single susceptor, or two or more separate susceptors. Terminals 130 of first inductor winding 124 and second inductor winding 126 may be coupled to PCB 122.

It should be appreciated that in some embodiments, the first and

second inductors

124, 126 may have at least one characteristic that is different from one another. For example, first inductive coil 124 may have at least one characteristic that is different from second inductive coil 126. More specifically, in one embodiment, the first inductor 124 may have a different inductance value than the second inductor 126. In fig. 7, the first inductor coil 124 and the second inductor coil 126 have different lengths such that the first inductor coil 124 is wound on a smaller section of the susceptor 132 than the second inductor coil 126. Thus, first inductor 124 may include a different number of turns than second inductor 126 (assuming that the spacing between the individual turns is substantially the same). In yet another embodiment, first inductor winding 124 may be made of a different material than second inductor winding 126. In some embodiments, the first inductor coil 124 and the second inductor coil 126 may be substantially identical.

In this embodiment, first inductor winding 124 and second inductor winding 126 are wound in opposite directions. This may be useful when the inductor is active at different times. For example, initially, first induction coil 124 may operate to heat a first section/portion of article 110, and at a later time, second induction coil 126 may operate to heat a second section/portion of article 110. Winding the coils in opposite directions helps to reduce the current induced in the inactive coils when used in conjunction with a particular type of control circuit. In fig. 7, the first inductor winding 124 is a right-hand spiral and the second inductor winding 126 is a left-hand spiral. However, in another embodiment, the inductor coils 124, 126 may be wound in the same direction, or the first inductor coil 124 may be a left-hand spiral and the second inductor coil 126 may be a right-hand spiral.

The susceptor 132 of this embodiment is hollow and thus defines a reservoir within which the aerosol-generating material is received. For example, the article 110 may be inserted into the susceptor 132. In this embodiment, the susceptor 120 is tubular with a circular cross-section.

The susceptor 132 may be made of one or more materials. Preferably, the susceptor 132 comprises carbon steel with a coating of nickel or cobalt.

In some embodiments, the susceptor 132 may include at least two materials that can be heated at two different frequencies for selectively atomizing the at least two materials. For example, a first section of the susceptor 132 (heated by the first induction coil 124) may comprise a first material and a second section of the susceptor 132 (heated by the second induction coil 126) may comprise a second, different material. In another embodiment, the first section may contain a first material and a second material, where the first material and the second material may be heated differently based on the operation of the first induction coil 124. The first material and the second material may be adjacent along an axis defined by the susceptor 132, or may form different layers within the susceptor 132. Similarly, the second section may include a third material and a fourth material, where the third material and the fourth material may be heated differently based on operation of the second induction coil 126. The third material and the fourth material may be adjacent along an axis defined by the susceptor 132, or may form different layers within the susceptor 132. For example, the third material may be the same as the first material, and the fourth material may be the same as the second material. Alternatively, each material may be different. The susceptor may comprise, for example, carbon steel or aluminum.

The apparatus 100 of fig. 7 also includes an insulating member 128, which may be substantially tubular and at least partially surrounds the susceptor 132. For example, the insulating member 128 may be constructed of any insulating material, such as plastic. In this particular embodiment, the insulating member is constructed of Polyetheretherketone (PEEK). The insulating member 128 may help insulate various components of the apparatus 100 from heat generated in the susceptor 132.

The insulating member 128 may also fully or partially support the first and

second inductors

124, 126. For example, as shown in fig. 7, the first and

second inductors

124, 126 are positioned around the insulating member 128 and are in contact with the radially outward surface of the insulating member 128. In some embodiments, the insulating member 128 does not abut the first and

second inductors

124, 126. For example, there may be a small gap between the outer surface of the insulating member 128 and the inner surfaces of the first and second induction coils 124, 126.

In a particular embodiment, the susceptor 132, the insulating member 128, and the first and second induction coils 124, 126 are coaxial about a central longitudinal axis of the susceptor 132.

Fig. 8 shows a side view in partial cross-section of the apparatus 100. In this embodiment there is a housing 102. The rectangular cross-sectional shape of the first and

second inductors

124, 126 is more clearly visible.

The apparatus 100 also includes a support 136 that engages an end of the susceptor 132 to hold the susceptor 132 in place. The support 136 is connected to the second end member 116.

The device may also include a second printed circuit board 138 associated with the control element 112.

The device 100 further comprises a second cap 140 and a spring 142 arranged towards the distal end of the device 100. The spring 142 allows the second cover 140 to open to provide access to the susceptor 132. The user may open the second cover 140 to clean the susceptor 132 and/or the support 136.

The device 100 also includes an expansion chamber 144 that extends away from the proximal end of the susceptor 132 toward the opening 104 of the device. Located at least partially within the expansion chamber 144 is a retaining clip 146 to abut and retain the article 110 when the article 110 is received within the apparatus 100. Expansion chamber 144 is connected to end member 106.

Fig. 9 is an exploded view of the device 100 of fig. 8, with the housing 102 omitted.

Fig. 10A shows a cross-section of a portion of the apparatus 100 of fig. 8. Fig. 10B shows a close-up view of the region of fig. 10A. Fig. 8A and 8B show the article 110 contained within a susceptor 132, wherein the article 110 is sized such that an outer surface of the article 110 abuts an inner surface of the susceptor 132. This ensures that heating is most efficient. The article 110 of this embodiment comprises an aerosol-generating material 110 a. The aerosol-generating material 110a is positioned within the susceptor 132. The article 110 may also include other components (such as filters, packaging, and/or cooling structures).

Figure 10B shows that the outer surface of the susceptor 132 is spaced from the inner surfaces of the inductor coils 124, 126 by a distance 150, which is measured in a direction perpendicular to the longitudinal axis 158 of the susceptor 132. In particular embodiments, the distance 150 is about 3mm to 4mm, about 3mm to 3.5mm, or about 3.25 mm.

Figure 10B further illustrates that the outer surface of the insulating member 128 is spaced from the inner surfaces of the inductor coils 124, 126 by a distance 152 measured in a direction perpendicular to the longitudinal axis 158 of the susceptor 132. In one particular embodiment, the distance 152 is about 0.05 mm. In another embodiment, the distance 152 is substantially 0mm such that the

inductive coils

124, 126 abut and contact the insulating member 128.

In one embodiment, the susceptor 132 has a wall thickness 154 of about 0.025mm to 1mm, or about 0.05 mm.

In one embodiment, the susceptor 132 has a length of about 40mm to 60mm, about 40mm to 45mm, or about 44.5 mm.

In one embodiment, the insulating member 128 has a wall thickness 156 of about 0.25mm to 2mm, 0.25mm to 1mm, or about 0.5 mm.

In use, the

articles

1, 1 ', 1 "', 1" ", described herein, may be inserted into a non-combustible aerosol-providing device (such as the device 100 described with reference to fig. 6-10). At least a portion of the

mouthpiece

2, 2 ', 2 "', 2" ", of the

article

1, 1 ', 1"', 1 "", projects from the non-combustible aerosol provision device 100 and may be placed into the mouth of a user. The aerosol is generated by heating the aerosol generating material 3 using the apparatus 100. The aerosol generated by the aerosol-generating material 3 passes through the

mouthpiece

2, 2 ', 2 "', 2" ", to the mouth of the user.

The

articles

1, 1 ', 1 "', 1" ", described herein have particular advantages, for example, when used with a non-flammable aerosol-providing apparatus, such as the apparatus 100 described with reference to fig. 6-10. In particular, it has been surprisingly found that the body 6 of amorphous solid material has a significant effect on the temperature of the aerosol delivered to the mouth end of the

article

1, 1 ', 1 "', 1" ", in use.

Tests were performed on two comparative smoking articles and exemplary embodiments of the present invention. Comparative examples a and B are the same as article 1 ", except that comparative examples a and B include bodies 4 of fibrous material instead of bodies 6 of amorphous solid material. Comparative example a had an aeration level of 60% and comparative example B had an aeration level of 75%. The exemplary article was identical to article 1 "and had 60% ventilation.

The first 2 puffs on the article were tested. Each sample was tested 9 times and the temperature provided was the average of these 9 tests. The known canadian ministry of health intense suction protocol (55 ml suction volume applied every 30 seconds for 2 seconds) was applied using standard test equipment. The test results are shown in table 1.0, where the draw temperature represents the difference between room temperature and aerosol temperature.

As shown in table 1.0, during the first and second puffs of the exemplary article comprising the amorphous solid material body, the aerosol temperature was lower than those of comparative examples a or B during these puffs. The aerosol temperature at 60% ventilation across

puffs

1 and 2 for the exemplary article is comparable to the aerosol temperature at 75% ventilation across

puffs

1 and 2 of comparative example B. Higher ventilation levels have a cooling effect on the aerosol temperature, so it is important to achieve comparable aerosol temperatures in articles with lower ventilation levels of 15%.

TABLE 1.0

Fig. 11 illustrates a method of manufacturing an article for use in a non-combustible aerosol provision system. In step S101, a source of amorphous solid material in sheet form is passed through an apparatus to form the sheet material into a rod of aggregated amorphous solid material.

At step S102, the gathered rod of amorphous solid material is cut to length to form a body of amorphous solid material as defined herein.

Figure 12 is a side view of an apparatus showing a rod for producing a body of material according to the present invention.

Fig. 12 shows a device 200 for producing a rod of a body of material according to the invention and comprising a tongue 211, a guiding nozzle 212 comprising a funnel part. The tongue 211 is a tapered tube with a wide entrance opening 211b and a narrow exit opening 211 a. The tongue 211 is generally circular in cross section and opens at its underside in the form of an elongated groove (not shown) extending along its length in its axial direction, so that the tongue 211 does not completely form a complete circle in cross section. The tongue 211 is located on a rod forming guide (not shown) that includes a forming track along which a continuous belt or "garniture" 215 extends. The fitting 215 extends over a plurality of guide rollers 216 and is driven to pass around the rollers 216 in the direction indicated by arrow "a". The wrapping paper 'P' is fed from the reel 217 onto the upper surface of the fitting 215, and is conveyed through the tongue 211 by the moving fitting 215. As the wrapper P travels through the tongue 211, the shaped track is configured to deform the fitment and the wrapper P thereon such that, in cross-section, the wrapper P changes from flat (as in the roll 217) as it enters the wide entry opening 11b of the tongue 211 to a closed circle as it exits the narrow exit opening 211a of the tongue 211, completely encircling the formed rod.

In use, a spool of amorphous solid material (not shown) is fed into the funnel of the guide nozzle 212 and directed into the tongue 211, the amorphous solid material being fed through the continuously tapered tongue 211 to form the sheet of amorphous solid material into a rod by gathering the material as it emerges from the narrow distal end 211 a.

When the amorphous solid material is fed into the tongue 211, it is gathered on the packaging material P conveyed on the fitment 215, and conveyed by the tongue 211 together therewith. As the amorphous solid material travels through the tongue 211, it is compressed as the tongue 211 tapers inwardly, and the wrapper P folds around the outside of the compressed cylinder of gathered amorphous solid material, such that when it exits through the narrow outlet opening 211a of the tongue 211 it is formed into a compressed cylindrical rod surrounded by the outer wrapper P.

The rod formed by the method described herein may then be cut to length to form a plurality of bodies 6 according to the present invention.
