Description

Consumables comprising two different aerosol generating materials for a non-flammable aerosol providing device

The present invention relates to consumables for use with a non-flammable aerosol providing device, the consumables comprising an aerosol generating material comprising an amorphous solid.

Smoking consumables, such as cigarettes, cigars, etc., generate tobacco smoke by burning a cigarette during use. Alternatives to these types of consumables release inhalable aerosols or vapors by heating rather than burning to release compounds from the substrate material. These may be referred to as non-combustible smoking consumables or aerosol generating assemblies.

One example of such an article is a heating device, which releases compounds by heating but not burning the aerosol generating solid material. This aerosol generating solid material may, in some cases, comprise tobacco material. Heating volatilizes at least one component of the material, typically forming an inhalable aerosol. These products may be referred to as non-combustible heating devices, tobacco heating devices or tobacco heating products. Various other arrangements are known for volatilizing at least one component of an aerosol generating solid material.

As another example, hybrid devices exist. These include a liquid source (which may or may not contain nicotine) that is evaporated by heating to generate an inhalable vapor or aerosol. The device further comprises an aerosol generating solid material, which may or may not comprise tobacco material, wherein components of the material are entrained in an inhalable vapor or aerosol to generate an inhalation medium.

Amorphous solid composition

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

In some cases, the amorphous solid may have a thickness of from about 0.015 mm to about 1.0 mm. Suitably, the thickness may range from about 0.05 mm, 0.1 mm, or 0.15 mm to about 0.5 mm, 0.3 mm or 0.2 mm. We have found that an amorphous solid having a thickness of 0.2 mm is particularly suitable. In some embodiments, the amorphous solid may have a thickness of about 0.1 to 0.2 mm. An amorphous solid may include more than one layer, and the thicknesses described herein refer to the collective thickness of these layers.

The inventors have established that heating efficiency is compromised if the amorphous solid is too thick. This adversely affects power consumption during use. Conversely, if the amorphous solid is too thin, it is difficult to manufacture and handle; Very thin materials are more difficult to cast, brittle and can impair aerosol formation in use.

The inventors have established that the amorphous solid thickness defined herein optimizes material properties in light of these conflicting considerations. The thickness defined 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 solids can be heated to generate an aerosol once. In some cases, the amorphous solids may be heated to generate more than one aerosol, such as two or three times.

Thicker amorphous solids may be used if the amorphous solid has to be heated more than once. For example, in some embodiments the thickness may be between 0.2 and 0.5 mm.

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

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

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

In embodiments, the coalescent comprises or consists of calcium acetate, calcium formate, calcium carbonate, calcium hydrogen carbonate, calcium chloride, calcium lactate, or combinations thereof. In some embodiments, the coalescent comprises or consists of calcium formate and/or calcium lactate. In certain instances, the coalescent comprises or consists of calcium formate. The inventors have found that typically, the use of calcium formate as the coalescent results in an amorphous solid with greater tensile strength and greater resistance to elongation.

The total amount of coalescents, such as calcium sources, may be 0.5 to 5 wt % (calculated on a dry weight basis). Suitably, the total amount may be from about 1 wt %, 2.5 wt % or 4 wt % to about 4.8 wt % or 4.5 wt %. The inventors have found that the addition of too little amount of coalescing agent can lead to an amorphous solid that does not stabilize the amorphous solid components and can result in these components falling out of the amorphous solid. The inventors have found that adding too much coalescent results in a very sticky amorphous solid and consequently poor handleability.

When the amorphous solid does not retain tobacco, a higher amount of coalescent may need to be applied. Thus, in some cases, the total amount of coalescing agent may be 0.5 to 12 wt %, such as 5 to 10 wt % (calculated on a dry weight basis). Suitably, the total amount may be from about 5 wt %, 6 wt % or 7 wt % to about 12 wt % or 10 wt %. In this case, the amorphous solid generally does not retain any tobacco.

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

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

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

In some embodiments, the gelling agent may include one or more compounds selected from cellulosic gelling agents, non-cellulosic gelling agents, guar gum, acacia gum, and mixtures thereof.

In some embodiments, the gelling agent comprises (or is one or more of) one or more of hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methylcellulose (HPMC), carboxymethylcellulose, guar gum, or acacia gum.

In some embodiments, the gelling agent is agar, xanthan gum, gum Arabic, guar gum, locust bean gum, pectin, carrageenan , one or more non-cellulosic gelling agents including, but not limited to, starch, alginate, and combinations thereof. In preferred embodiments, the non-cellulosic gelling agent is alginate or agar.

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

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

In embodiments where the amorphous solid comprises a flavoring agent, suitably the amorphous solid comprises up to about 60 wt%, 50 wt%, 40 wt%, 30 wt%, 20 wt%, 10 wt% or 5 wt% flavoring agent. In some cases, the amorphous solid may comprise at least about 0.5 wt %, 1 wt %, 2 wt %, 5 wt %, 10 wt %, 20 wt %, or 30 wt % of a flavoring agent, all calculated on a dry weight basis. For example, the amorphous solid may include 0.1 to 60 wt%, 1 to 60 wt%, 5 to 60 wt%, 10 to 60 wt%, 20 to 50 wt%, or 30 to 40 wt% of a flavoring agent. In some cases, the flavoring agent (if present) comprises, consists essentially of, or consists of menthol. In some cases, the amorphous solid is flavorless.

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

In embodiments where the amorphous solid comprises an acid, the amorphous solid comprises 1 to 20 wt%, 5 to 15 wt% or 8 to 12 wt% (calculated on a dry weight basis) of an acid, e.g., 1 wt%, 2 wt%, 3 wt% or 4 wt % to about 20 wt %, 15 wt %, 10 wt % or 5 wt % (calculated on a dry weight basis) of acid.

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

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

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

In some such embodiments, the acid may have an acidic functional group having a pK _a value in the range of 2 to 6, for example in the range of 3 to 6 or 4 to 5, as measured at 25°C.

In some cases, the amorphous solid may comprise at least about 1 wt %, 2 wt %, or at least about 5 wt % water (WWB). The amorphous solid comprises from about 1 wt % to about 15 wt % water, or from about 5 wt % to about 15 wt % water calculated on a wet weight basis. Suitably, the moisture content of the amorphous solid may be from about 5 wt %, 7 wt % or 9 wt % to about 15 wt %, 13 wt % or 11 wt % (WWB), most suitably about 10 wt %.

The amorphous solid may be prepared as a gel, and the gel may further include a solvent contained in an amount of 0.1 to 50 wt%. However, the present inventors have established that the inclusion of a solvent in which the flavoring agent is soluble can reduce gel stability, and the flavoring agent can crystallize from the gel. Thus, in some cases, the gel does not include a solvent in which the flavoring agent is soluble.

Inorganic adsorbents may be included. The filler may include one or more organic filler materials, such as wood pulp, cellulose and cellulose derivatives (such as methylcellulose, hydroxypropyl cellulose, and carboxymethyl cellulose (CMC)). In some cases, the amorphous solid comprises less than 1 wt % filler, and in some cases no filler. In particular, in some cases, the amorphous solid does not include calcium carbonate, such as chalk.

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

In some embodiments, the amorphous solid does not include tobacco fibers. In certain embodiments, the amorphous solid does not include a fibrous material.

In some embodiments, the aerosol generating material does not include tobacco fibers. In certain embodiments, the aerosol generating material does not comprise a fibrous material.

In some examples, such as where the amorphous solid comprises a filler, the amorphous solid can have a tensile strength of 600 N/m to 900 N/m, or 700 N/m to 900 N/m, or about 800 N/m.

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

Various 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 envisioned. Natural or synthetic colorants may be used, such as natural or synthetic dyes, food-grade colorants and pharmaceutical-grade colorants. In certain embodiments, the colorant is caramel, which can give an amorphous solid with a brown appearance. In such embodiments, the color of the amorphous solid may be similar to the color of other components of the aerosol generating material comprising the amorphous solid (eg, tobacco material). In some embodiments, the addition of a colorant to the amorphous solid renders the amorphous solid visually indistinguishable from other components of the aerosol generating material.

The colorant may be incorporated during the formation of the amorphous solid (eg, when forming a slurry comprising materials that form the amorphous solid) or (eg, by spraying the colorant onto the amorphous solid) or the formation of the amorphous solid. It can then be applied to the amorphous solid.

Expendables

In some cases, aerosol generating materials (eg, first and second aerosol generating materials) are attached to a support. Advantageously, the support is a planar support. In some cases, the support may be substantially or wholly impermeable to gases and/or aerosols. This prevents the passage of aerosols or gases through the support, thereby controlling the flow and ensuring good delivery to the user. It can also be used, for example, to prevent condensation or other deposition of gases/aerosols in use on the surface of a heater provided in a non-flammable aerosol providing system. Thus, consumption efficiency and hygiene may be improved in some cases.

These weights are calculated on a dry weight basis; and

The amorphous solid of the first aerosol-generating material has a different composition than the amorphous solid of the second aerosol-generating material.

The support may be at least partially porous in the region of the surface that encounters the amorphous solid. The inventors have found that such supports are particularly suitable for the present invention; The porous portion of the support contacts the amorphous solid and forms a strong bond. The amorphous solid is formed by drying the gel, and without being limited by theory, the slurry forming the amorphous solid may partially impregnate the porous material of the support so that the amorphous solid hardens and forms cross-links. In this case, it is contemplated that the support is partially bound to the amorphous solid. This provides a strong bond between the amorphous solid and the support.

Additionally, the surface roughness can contribute to the bond strength between the amorphous solid and the support. The inventors have determined that the paper roughness (for the surface abutting the aerosol generating material) is suitably 50 to 1000 Bekk sec, suitably 50 to 150 Bekk sec, suitably 100 Beck sec (atmospheric pressure of 50.66 to 48.00 kPa). measured over the interval). (Beck smoothness tester is a tool used to determine the smoothness of a paper surface that leaks air at a specified pressure between a smooth glass surface and a paper sample, and the time (in seconds) for a fixed volume of air to seep between these surfaces is called "Beck smoothness" "lim)

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

In one particular case, the support itself may be a laminate structure. For example, the support may comprise a cardboard-backed foil; The cardboard layer is brought into contact with the amorphous solid and the properties discussed in the previous paragraphs are provided by this contact. The foil backing is substantially impermeable to provide control of the aerosol flow path. In addition, the metal foil backing can serve to conduct heat to the amorphous solid.

In other cases, the foil layer of the cardboard-backed foil abuts the amorphous solid. The foil is substantially impermeable, thereby preventing water provided to the amorphous solid from being absorbed into the paper and weakening its structural integrity.

In some cases, the support is formed of or comprises a metal foil, such as an aluminum foil. The metal support may allow better conduction of thermal energy to the amorphous solid. Additionally or alternatively, the metal foil may function as a susceptor in an induction heating system. In certain embodiments, the support comprises a metal foil layer and a support layer, such as cardboard. In such embodiments, the metal foil layer may have a thickness of less than 20 μm, such as from about 1 μm to about 10 μm, suitably about 5 μm.

Alternatively, the consumable may be referred to herein as a cartridge. The consumable may be configured for use with a THP, hybrid device or other aerosol generating device. In some cases, the consumable may be in the form of a rod. In some cases, the consumable may further include a filter and/or cooling element, as previously described. In some cases, the consumable may be surrounded by a wrapping material such as paper.

The consumable may further include ventilation apertures. These may be provided on the sidewall of the consumable. In some cases, vent holes may be provided in the filter and/or cooling element. These apertures may allow cooling air to be sucked into the consumable during use, which may mix with the heated volatile components, thereby cooling the aerosol.

Ventilation enhances the production of visible heated volatilized components from the consumable as the consumable is heated in use. The heated volatilized components are made visible by a process of cooling the heated volatilized components such that supersaturation of the heated volatilized components occurs. The heated volatilized components are then subjected to droplet formation—otherwise known as nucleation—and, eventually, the size of the aerosol particles of the heated volatilized components is It is increased by further condensation of the heated components and coagulation of newly formed droplets from the heated volatilized components.

In some cases, the ratio of the cooling air to the sum of the cooling air and the heated volatilized components (known as the aeration ratio) is at least 15%. An aeration rate of 15% allows the heated volatilized components to be visualized by the method described above. The visibility of the heated volatilized ingredients allows the user to identify that the volatilized ingredients have been produced and add to the sensory experience of the smoking experience.

In another example, the aeration rate is between 50% and 85% to provide additional cooling to the heated volatilized components. In some cases, the ventilation rate may be at least 60% or 65%.

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

An example consumable 101 is substantially in the form of a cylindrical rod, which includes a filter assembly 105 and a body of aerosol generating material 103 in the form of a rod. Aerosol generating materials include the amorphous solid materials described herein. In some embodiments, the aerosol generating material may be included in the form of a sheet. In some embodiments, the aerosol generating material may be included in the form of a shredded sheet. In some embodiments, the aerosol generating material described herein may be incorporated in sheet form and crushed form.

The filter assembly 105 comprises three segments; a cooling segment 107 , a filter segment 109 and a mouth end segment 111 . The consumable 101 has a first end 113 , also known as a mouth or proximal end, and a second end 115 , also known as a distal end. The body of the aerosol generating material 103 is positioned towards the distal end 115 of the consumable 101 . In one example, the cooling segment 107 is positioned adjacent the body of the aerosol-generating material 103 between the body of the aerosol-generating material 103 and the filter segment 109 such that the cooling segment 107 is aerosol-generating. is in abutting relationship with material 103 and filter segment 109 . In other examples, there may be a gap between the body of the aerosol generating material 103 and the cooling segment 107 , and between the body of the aerosol generating material 103 and the filter segment 109 . The filter segment 109 is positioned between the cooling segment 107 and the mouth end segment 111 . The mouth end segment 111 is positioned towards the proximal end 113 of the consumable 101 adjacent the filter segment 109 . In one example, filter segment 109 is in abutting relationship with mouth end segment 111 . In one embodiment, the overall length of the filter assembly 105 is between 37 mm and 45 mm, more preferably the overall length of the filter assembly 105 is 41 mm.

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

In one example, the overall length of the consumable 101 is 71 mm to 95 mm, suitably 79 mm to 87 mm, suitably about 83 mm.

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

The body of the aerosol generating material 103 is bonded to the filter assembly 105 by an annular tipping paper (not shown), which tipping paper substantially surrounds the filter assembly 105 ( It is located around the circumference of 105 and extends partially along the length of the body of the aerosol generating material 103 . In one example, the tipping paper is made of 58GSM standard tipping base paper. In one example, the tipping paper has a length of between 42 mm and 50 mm, suitably about 46 mm.

In one example, cooling segment 107 is an annular tube, positioned around the cooling segment and defining an air gap within the cooling segment. The voids provide a chamber through which the heated volatilized components generated from the body of the aerosol generating material 103 flow. The cooling segment 107 is hollow to provide a chamber for aerosol accumulation, but avoids axial compressive forces and bending moments that may arise during manufacture and while the consumable 101 is being inserted into the device 51 in use. It has enough strength to withstand it. In one example, the thickness of the wall of the cooling segment 107 is approximately 0.29 mm.

The cooling segment 107 provides a physical displacement between the aerosol generating material 103 and the filter segment 109 . The physical displacement provided by the cooling segment 107 will provide a thermal gradient over the length of the cooling segment 107 . In one example, the cooling segment 107 is at least 40° C. between the heated volatilized component entering the first end of the cooling segment 107 and the heated volatilized component exiting the second end of the cooling segment 107 . is configured to provide a temperature difference of In one example, the cooling segment 107 is at least 60° C. between the heated volatilized component entering the first end of the cooling segment 107 and the heated volatilized component exiting the second end of the cooling segment 107 . is configured to provide a temperature difference of This temperature difference over the length of the cooling element 107 protects the temperature sensitive filter segment 109 from the high temperature of the aerosol generating material 103 when the aerosol generating material 103 is heated by the device 51 . If no physical displacement is provided between the filter segment 109 and the body of the aerosol generating material 103 and the heating elements of the device 51 , the temperature sensitive filter segment 109 is damaged in use, so its requirements It will not perform its functions effectively.

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

The cooling segment 107 may be made of paper, which states that the cooling segment 107 is constructed of a material that does not generate compounds of interest, eg, toxic compounds, when in use adjacent to the heater of the device 51 . means that In one example, the cooling segment 107 is made of a spirally wound paper tube that provides a hollow inner chamber, but maintains mechanical rigidity. Spirally wound paper tubes can meet the stringent dimensional accuracy requirements of high-speed manufacturing processes with respect to tube length, outer diameter, roundness and straightness.

In another example, the cooling segment 107 is a stiff plug wrap or recess created in tipping paper. The rigid plug wrap or tipping paper is manufactured to have sufficient stiffness to withstand bending moments and axial compressive forces that may occur during manufacture and while the consumable 101 is being inserted into the device 51 in use.

Filter segment 109 may be formed of any filter material sufficient to remove one or more volatilized compounds from heated volatilized components from the aerosol generating material. In one example, filter segment 109 is made of a mono-acetate material such as cellulose acetate. Filter segment 109 provides cooling and irritation-reduction from heated volatilized components without depleting the amount of heated volatilized components to an unsatisfactory level for the user.

In some embodiments, a capsule (not illustrated) may be provided in the filter segment 109 . The capsule may be disposed substantially central to the filter segment 109 across the filter segment 109 diameter and along the length of the filter segment 109 . In other cases, the capsule may be offset in one or more dimensions. Capsules, if present, may in some cases retain volatile ingredients such as flavoring agents or aerosol generators.

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

In one example, the filter segment 109 is made of 8Y15 grade filter tow material, which provides a filtering effect to the heated volatilized material while reducing the size of condensed aerosol droplets arising from the heated volatilized material. .

The presence of the filter segment 109 provides an insulating effect by providing additional cooling to the heated volatilized components exiting the cooling segment 107 . This additional cooling effect reduces the contact temperature of the user's lips on the surface of the filter segment 109 .

In one example, filter segment 109 is between 6 mm and 10 mm in length, more suitably about 8 mm.

The mouth end segment 111 is an annular tube and is positioned around it and defines a void within the mouth end segment 111 . The voids provide a chamber for the heated volatilized components flowing from the filter segment 109 . Mouth end segment 111 is hollow to provide a chamber for aerosol accumulation, but to withstand axial compressive forces and bending moments that may occur during manufacture and while a consumable is being inserted into device 51 in use. have sufficient rigidity. In one example, the thickness of the wall of the mouth end segment 111 is approximately 0.29 mm. In one example, the length of the mouth end segment 111 is between 6 mm and 10 mm, suitably about 8 mm.

Mouth end segment 111 may be made of a spirally wound paper tube that provides a hollow inner chamber but maintains critical mechanical stiffness. Spirally wound paper tubes can meet the stringent dimensional accuracy requirements of high-speed manufacturing processes with respect to tube length, outer diameter, roundness and straightness.

The mouth end segment 111 serves to prevent any liquid condensate that has accumulated at the outlet of the filter segment 109 from direct contact with the user.

In one example, the mouth end segment 111 and the cooling segment 107 may be formed of a single tube, and the filter segment 109 is positioned within that tube separating the mouth end segment 111 and the cooling segment 107 . It should be understood that

3 and 4 , a partially cut-away cross-sectional view and a perspective view of an example of the consumable 301 are shown. Reference numerals shown in Figs. 3 and 4 are the same as those shown in Figs. 1 and 2, but incremented by 200.

In the example of the consumable 301 shown in FIGS. 3 and 4 , a ventilation zone 317 is provided in the consumable 301 so that air can flow from the outside of the consumable 301 to the inside of the consumable 301 . . In one example, the ventilation zone 317 takes the form of one or more ventilation holes 317 formed through the outer layer of the consumable 301 . Vent holes may be located in the cooling segment 307 to aid cooling of the consumable 301 . In one example, the vent region 317 includes one or more rows of holes, preferably each row of holes is a consumable in a cross section substantially perpendicular to the longitudinal axis of the consumable 301 . 301) are arranged circumferentially around the perimeter.

In one example, there are 1 to 4 rows of ventilation holes to provide ventilation for the consumable 301 . Each row of ventilation holes may have 12 to 36 ventilation holes 317 . The ventilation holes 317 may have a diameter of 100 to 500 μm, for example. In one example, the axial separation between the rows of vent holes 317 is between 0.25 mm and 0.75 mm, suitably 0.5 mm.

In one example, the ventilation holes 317 are uniform in size. In another example, the vent holes 317 vary in size. Vent holes may be manufactured using any suitable technique, for example one or more of the following techniques: laser technique, mechanical drilling of cooling segment 307 , or cooling segment 307 into consumable 301 . Pre-drilling of cooling segments 307 before forming. The vent holes 317 are positioned to provide effective cooling to the consumable 301 .

In one example, the rows of vent holes 317 are located at least 11 mm from the proximal end 313 of the consumable, and suitably located between 17 mm and 20 mm from the proximal end 313 of the consumable 301 . The position of the ventilation holes 317 is positioned so that the user does not block the ventilation holes 317 when the consumable 301 is used.

Providing rows of vent holes 17 to 20 mm from the proximal end 313 of the consumable 301 when the consumable 301 is fully inserted into the device 51 , as can be seen in FIGS. 6 and 7 . , allowing the ventilation holes 317 to be located on the outside of the device 51 . By locating the vent holes on the outside of the device, unheated air can enter the consumable 301 through the vent holes from the outside of the device 51 to help cool the consumable 301 .

The length of the cooling segment 307 is such that when the consumable 301 is fully inserted into the device 51 , the cooling segment 307 is partially inserted into the device 51 . The length of the cooling segment 307 has a primary function of providing a physical gap between the heater arrangement of the device 51 and the heat-sensitive filter arrangement 309, and with the vent holes 317 located in the cooling segment, It also provides a second function that allows the consumable 301 to be positioned on the outside of the device 51 when fully inserted into the device 51 . 6 and 7 , most of the cooling element 307 is located within the device 51 . However, there is a portion of the cooling element 307 extending out of the device 51 . It is this part of the cooling element 307 that extends out of the device 51 in which the ventilation holes 317 are located.

Referring now in more detail to FIGS. 5-7 , a device arranged to heat an aerosol-generating material to volatilize at least one component of the aerosol-generating material, typically to form an aerosol that can be inhaled. An example of (51) is shown. Device 51 is a heating device, which releases compounds by heating but not burning the aerosol generating material.

The first end 53 is sometimes referred to herein as the mouth or proximal end 53 of the device 51 , and the second end 55 is sometimes referred to herein as the distal end 55 of the device 51 . do. The device 51 has an on/off button 57 that allows the entire device 51 to be switched on and off as desired by the user.

Device 51 includes a housing 59 for positioning and protecting various internal components of device 51 . In the example shown, the housing 59 comprises a top panel 17 that generally defines the 'top' of the device 51 and a top panel 17 that generally defines the 'bottom' of the device 51 . a uni-body sleeve 11 surrounding the perimeter of the device 51 which is capped with a lowermost panel 19 . In another example, the housing includes a front panel, a rear panel, and a pair of opposing side panels in addition to the top panel 17 and the bottom panel 19 .

The top panel 17 and/or the bottom panel 19 may be removably secured to the single-body sleeve 11 to allow easy access to the interior of the device 51 , or ) to "permanently" to prevent, for example, a user from accessing the interior of the device 51 . In one example, panels 17 and 19 are made of a plastic material including, for example, glass-filled nylon formed by injection moulding, and a single-body sleeve. (11) is made of aluminum, although other materials and other manufacturing processes may be used.

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

Housing 59 places or secures heater arrangement 23 , control circuitry 25 and power source 27 therein. In this example, the heater arrangement 23 , the control circuitry 25 and the power source 27 are sideways, with the control circuitry 25 generally positioned between the heater arrangement 23 and the power source 27 . directionally (ie, adjacent when viewed from one end), but other locations are possible.

The control circuitry 25 may include a controller, such as a microprocessor arrangement, constructed and arranged to control heating of the aerosol generating material within the consumables 101 , 301 , as discussed further below.

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

An advantage of positioning the power supply 27 laterally adjacent to the heater arrangement 23 is that a physically large power supply 27 can be used without unduly elongating the entire device 51 . As will be appreciated, in general, a physically larger power source 27 has a greater capacity (ie, the total electrical energy that can be supplied, often measured in Amp-hours, etc.), and thus The battery life will be longer.

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

In one particular example, the heater arrangement 23 is supported by a stainless steel support tube and includes a polyimide heating element. The heater arrangement 23 is such that substantially the entirety of the body of the aerosol generating material 103 , 303 of the consumables 101 , 301 is the heater arrangement 23 when the consumables 101 , 301 are inserted into the device 51 . ) is dimensioned to be inserted into

The or each heating element may be arranged such that selected zones of aerosol generating material can be heated independently, eg, as desired, one after the other (over time as discussed above) or together (simultaneously). can

The heater arrangement 23 in this example is surrounded along at least part of its length by a thermal insulator 31 . The insulation 31 helps reduce heat passing from the heater arrangement 23 to the outside of the device 51 . The insulation helps to lower the power requirements for the heater arrangement 23 because it generally reduces heat loss. The insulation 31 also helps to keep the exterior of the device 51 cool during operation of the heater arrangement 23 . In one example, the insulation 31 may be a double walled sleeve that provides a low pressure zone between the two walls of the sleeve. That is, the insulation 31 may be, for example, a “vacuum” tube, ie, a tube that is at least partially evacuated to minimize heat transfer by conduction and/or convection. In addition to or instead of the double-walled sleeve, insulating material 31 , comprising, for example, using heat insulating materials comprising a suitable foam-type material. Other arrangements for this are possible.

The housing 59 may further include various internal support structures 37 for supporting the heating arrangement 23 as well as all internal components.

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

The collar 33 comprises a plurality of ridges 60 arranged circumferentially around the perimeter of the opening 20 and projecting into the opening 20 . The ridges 60 are such that the open span of the opening 20 at the positions of the ridges 60 is less than the open span of the opening 20 at the positions without the ridges 60 . It takes up space within the opening 20 . Ridges 60 are configured to engage consumables 101 , 301 that are inserted into device 51 to help secure the device within device 51 . Open spaces (not shown in the figures) defined by adjacent pairs of ridges 60 and consumables 101 , 301 form ventilation paths around the outer perimeter of consumables 101 , 301 . These vent paths allow hot vapors escaped from the consumables 101 , 301 to exit the device 51 and cooling air to the device 51 around the consumables 101 , 301 in the void 36 . allow flow in.

In operation, the consumables 101 , 301 are removably inserted into the insertion point 20 of the device 51 as shown in FIGS. 5-7 . In particular, referring to FIG. 6 , in one example, the body of aerosol generating material 103 , 303 positioned towards the distal end 115 , 315 of the consumable 101 , 301 is a heater arrangement of the device 51 ( 23) is fully accommodated in The proximal ends 113 , 313 of the consumables 101 , 301 extend from the device 51 and serve as a mouthpiece assembly for the user.

In operation, the heater arrangement 23 will heat the consumables 101 , 301 to volatilize at least one component of the aerosol generating material from the body of the aerosol generating material 103 , 303 .

The primary flow path for the volatilized components heated from the body of the aerosol generating material 103 , 303 is, axially, through the consumables 101 , 301 inside the cooling segments 107 , 307 . through the chamber of , through filter segments 109 , 309 , and through mouth end segments 113 , 313 to the user. In one example, the temperature of the heated volatilized components generated from the body of the aerosol generating material is between 60° C. and 250° C., which may exceed the user-acceptable inhalation temperature. As the heated volatilized components move through the cooling segments 107 , 307 , the cooled and some volatilized components will condense on the inner surface of the cooling segments 107 , 307 .

In the examples of consumable 301 shown in FIGS. 3 and 4 , cooling air may enter cooling segment 307 through vent holes 317 formed in cooling segment 307 . This cooling air will mix with the heated volatilized components to provide further cooling to the heated volatilized components.

Advantageously, the consumable of the present invention allows each of the first and second aerosol generating materials to be aerosolized separately. In other words, the generation of an aerosol from each aerosol-generating material may be under individual control, such that the generation of the aerosol generated by each aerosol-generating material may vary individually. In embodiments where the non-flammable aerosol providing system is heated to generate an aerosol, each aerosol generating material of the consumable may be under the control of a separate heat generating arrangement. In such embodiments, the temperature of each aerosol-generating material may be separately controlled to stimulate the release of a desired amount of aerosol from each aerosol-generating material. In this way, the non-combustible aerosol delivery system is configured to enable a user to aerosolize the first and/or second aerosol generating material according to personal preference. By way of non-limiting example provided to illustrate the present invention; The amorphous solid of the first aerosol generating material may comprise a flavoring agent and no active substance, whereas the amorphous solid of the second aerosol generating material may comprise the active substance and no flavorant; If the user wishes to inhale only the flavor, a non-flammable aerosol delivery system may allow this; For example, a user may program a non-flammable aerosol providing device to aerosolize a first aerosol generating material (including a flavoring agent) but not aerosolizing a second aerosol generating material (including an active substance). It will be appreciated that such a system may be further configured to enable a user to obtain a wide range of smoking experiences according to preferences.

In some embodiments, the aerosol generating materials will be arranged in the consumable such that they can be stimulated to generate an aerosol under separate control from each other when used in a non-combustible aerosol delivery system.

The advantage of the consumables of the present invention is that a single type of consumables can be manufactured in one manufacturing line or equipment, which can provide various experiences according to user preferences.

In some cases, a heater (eg, a heater in a non-flammable aerosol providing system) can heat amorphous solids in use without burning to 120° C. to 350° C. In some cases, the heater can heat the amorphous solids in use without burning to 140°C to 250°C.

The heater may comprise one or more electrically resistive heaters, including, for example, one or more nichrome resistive heater(s) and/or one or more ceramic heater(s). The one or more heaters may include one or more induction heaters comprising an arrangement comprising one or more susceptors capable of forming a chamber into which an article comprising an aerosol generating material is inserted or otherwise positioned in use. Alternatively or additionally, one or more susceptors may be provided in the aerosol generating material. Also, other heating arrangements may be used.
