Detailed Description

[0037] A first aspect of the invention provides a non-burning heating article comprising an aerosol generating medium and a filter, the filter containing one or more crushable capsules, in which, in use, the aerosol generating medium is heated without being burned and the capsule is exposed to a temperature of about 30-100ºC during which its structural integrity is not compromised, so that the capsule can be crushed by the user before, during or after heating.

[0038] The aerosol generated by an unburned heating product is typically hot and humid due to the nature of the heating profile and the composition of the aerosol generating medium. For example, the aerosol generating means in an unburned heating product according to the invention may contain a greater proportion of aerosol generating agent than a smokable material used in a combustible product. In addition, or alternatively, the aerosol generating medium in a non-burning heating product according to the invention can be heated to a high temperature and / or for a longer period than the temperature / burning period of a product fuel. The inventors have established that the capsules detailed in claim 1 are particularly suitable for use in a non-burning heating product and the conditions contained therein. The capsules stipulated in claim 1 have been found to be less likely to fail or break in exposure to conditions in an unburned heating product when compared to other capsules.

[0039] In some cases, in use, the aerosol generating medium generates a wet aerosol and the capsule is exposed to at least 12 mg of water.

[0040] The inventors established that the temperature profile of the center of the filter reaches its peak at the time of each puff during use. This is due to the hot aerosol being sucked through the filter during the swallow. In some cases, the capsule may be exposed to an excess temperature of around 30ºC, 40ºC or 50ºC during use. In some cases, the maximum temperature to which the capsule is exposed during use is less than about 100ºC, 90ºC, 80ºC or 70ºC. In some cases, the capsule can be exposed to temperatures in the range of 30ºC – 100ºC, suitably 40ºC-80ºC or 50ºC-70ºC.

[0041] As used in this document, the term "heating item without burning" refers to an article containing an aerosol generating means; in use, the components of the aerosol generating medium are volatilized by heating, without burning / combustion, from an inhalable vapor or aerosol.

[0042] The aerosol generating means of an unburned heating article comprises a solid component (in contrast to the aerosol generating means of electronic cigarettes in which the aerosol generating means is liquid). By "solid", it is understood that the aerosol generating medium does not exhibit any flow when it is in a steady state. The solid may include gels and the like. For the avoidance of doubt, the aerosol generating means of a non-burning heating article may comprise, in addition to a solid component, a liquid component.

[0043] The capsule described here may have a core-shell structure. In such cases, the core comprises a liquid. In some cases, the core may comprise one or more aerosol-generating agents and / or one or more flavorings. In some cases, the core may comprise an acid, a base and / or water. In some cases, the core may comprise a solvent. In some particular cases, the nucleus may comprise menthol.

[0044] The shell material of the capsule (which may alternatively be referred to here as the barrier material or the encapsulation material) encapsulates the core. The shell material may, in some cases, work to minimize core migration during product storage. In some cases, the shell material may provide controlled release of the core during use. The capsule can be broken (i.e., crushed) to release the contents before, during or after heating the article for heating, without burning.

[0045] The shell material of the capsule can be crushed; that is, it is frangible or breakable. The capsule is crushed or otherwise fractured or broken by the user to release the contents. Normally, the capsule is broken just before heating is started, but the user can select when to release the contents (that is, it can be crushed after heating is started). The term "crushable capsule" refers to a capsule in which the encapsulating material (which may be a shell) can be broken by means of pressure to release the encapsulated material (which may be a core of the capsule); more specifically, the encapsulation material

(for example, shell) can be broken under the pressure imposed by the user's fingers (or any other means of creating pressure) when the user wants to release the contents of the capsule. In some cases, the capsule may have an initial crush (preheat) resistance of about 0.8 kp to about 3.5 kp, suitably from about 1.0 kp to about 20.5 kp or about 1.0 to about 2.0 kp. The inventors have established that the capsules can weaken with heating. The inventors have established that capsules with an initial crush resistance of at least 0.8 kp are less likely to break / break with heating. The inventors have established that capsules with a crush resistance of more than 3.5 kp are difficult to crush before heating. The inventors have determined that an initial crush resistance in the range of 1.0 kp to 2.0 kp provides the best performance of the capsule.

[0046] In some cases, the capsules described here can be substantially spherical and have a diameter of at least about 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm, 2.0 mm, 2 , 5 mm, 2.8 mm or 3.0 mm. The diameter of the capsules can be less than about 10.0 mm, 8.0 mm, 7.0 mm, 6.0 mm, 5.5 mm, 5.0 mm, 4.5 mm, 4.0 mm, 3.5 mm or 3.2 mm. Illustratively, the capsule diameter can be in the range of about 0.4 mm to about 10.0 mm, from about 0.8 mm to about 6.0 mm, from about 2.5 mm to about 5.5 mm or from about 2.8 mm to about 3.2 mm. In some cases, the capsule can have a diameter of about 3.0 mm to about 3.5 mm. These sizes are particularly suitable for incorporating the capsule into a filter for a non-burning heating article.

[0047] In some cases, the total weight of a capsule described here can be in the range of about 1 mg to about 100 mg, suitably from about 5 mg to about 60 mg, from about 10 mg to about 50 mg, from about 15 mg to about 40 mg, or from about 15 mg to about 30 mg.

[0048] In some cases, the total weight of the core formulation can be in the range of about 2 mg to about 90 mg, suitably from about 3 mg to about 70 mg, from about 5 mg to about 25 mg, from about 8 mg to about 20 mg, or from about 10 mg to about 15 mg.

[0049] The shell comprises 5 to 90% by weight based on the total weight of the shell of a gelling agent capsule, in which the gelling agent comprises, consists essentially of or consists of a carrageenan. In some cases, the shell comprises 5-60%, 5-50% or 10-35% by weight based on the total weight of the capsule shell of said gelling agent. In some cases, the gelling agent in the shell of the capsule comprises a carrageenan. In some cases, this carrageenan has a melting point of at least about 30 ° C or at least about 40 ° C.

[0050] In addition to carrageenan, the shell may comprise additional gelling agents. Suitable gelling agents that can be included in the shell material of the capsule can include, without limitation, polysaccharide or cellulosic gelling agents, gelatins, gums, gels, waxes or a mixture thereof. Suitable polysaccharides include alginates, dextrins, maltodextrins, cyclodextrins and pectins. Suitable alginates include, for example, an alginic acid salt, an esterified alginate or glyceryl alginate. Alginic acid salts include ammonium alginate, triethanolamine alginate and group I or II metal ion alginate salts, such as sodium, potassium, calcium and magnesium alginate. Esterified alginates include propylene glycol alginate and glyceryl alginate. In some examples, the barrier material comprises sodium alginate and / or calcium alginate. Suitable cellulosic materials include methylcellulose, ethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, carboxymethylcellulose, cellulose acetate and cellulose ethers. The gelling agent can comprise one or more modified starches. The gelling agent can comprise one or more carrageenans. Suitable gums include agar, gel gum, arabic gum, pullum gum, manna gum, ghatti gum, tragacanth gum, Karaya gum, locust bean gum, acacia gum, guar gum, quince seed and xanthan gum. Suitable gels include agar, agarose, carrageenan, furoidane and furcelaran. Suitable waxes include carnauba wax. In some cases, the gelling agent may comprise carrageenans and / or gellan gum; these gelling agents are particularly suitable for inclusion as the gelling agent since the pressure required to break the resulting capsules is particularly suitable. In some cases, the shell of the capsule does not comprise gelatin.

[0051] The shell of the capsule may additionally comprise one or more of a bulking agent, a buffer, a coloring agent, and a plasticizer.

[0052] In some cases, the material capsule may comprise one or more bulking agents, such as starches, modified starches (for example, oxidized starches) and sugar alcohols such as maltitol.

[0053] In some cases, the capsule material may comprise a coloring agent that makes it easier to locate the capsule within the tobacco industry product during manufacture. The coloring agent is preferably chosen from dyes and pigments.

[0054] In some cases, the capsule material may also comprise at least one buffer, such as a citrate or phosphate compound.

[0055] In some cases, the capsule material may also comprise at least one plasticizer, which may be glycerol, sorbitol, maltitol, triacetin, polyethylene glycol, propylene glycol or other polyalcohol with plasticizing properties, and, optionally, a monoacid type acid, diacid or tracid, especially citric acid, fumaric acid, malic acid and the like. In some cases, the amount of plasticizer ranges from 1% to 30% by weight, preferably from 2% to 15% by weight, and even more preferably from 3 to 10% by weight of the total weight of the shell. In some cases, the total amount of plasticizer and gelling agent combined in the shell is about 40-70%, suitably 50-60% by weight based on the total weight of the capsule shell. In some cases, the plasticizer comprises, consists essentially of or consists of glycerol.

[0056] In some cases, the shell of the capsule may also comprise one or more filler materials. Suitable filler materials include, comprising starch derivatives such as dextrin, maltodextrin, cyclodextrin (alpha, beta or gamma), or cellulose derivatives, such as hydroxypropylmethylcellulose (HPMC), hydroxypropylcellulose (HPC),

methylcellulose (MC), carboxymethylcellulose (CMC), polyvinyl alcohol, polyols or mixtures thereof. The capsule shell may, in some cases, comprise up to about 60% fill weight, based on the total weight of the capsule shell. In some cases, the shell of the capsule may comprise up to about 50%, 40%, 30% or 20% by weight of filler, based on the total weight of the shell of the capsule. In some particular cases, the capsule shell may not comprise any fillers.

[0057] The capsule shell may additionally comprise a hydrophobic outer layer that reduces the capsule's susceptibility to moisture-induced degradation. The hydrophobic outer layer is suitably selected from the group comprising waxes, especially carnauba wax, candelilla wax or beeswax, carbowax wax, shellac (in alcoholic or aqueous solution), ethylcellulose, hydroxypropylmethylcellulose, hydroxylpropylcellulose, composition of latex, polyvinyl alcohol, or a combination thereof. More preferably, at least one moisture barrier agent is ethyl cellulose or a mixture of ethyl cellulose and shellac.

[0058] Capsule preparation methods include coextrusion, optionally followed by centrifugation and curing and / or drying. These and other suitable techniques are known in the art.

[0059] The filter may comprise a filter material. For example, the filter may comprise a cellulosic material, such as cellulose acetate, a ceramic material, polylactic acid, a polymeric matrix and / or activated carbon. Suitable examples of ceramic materials include silicon carbide

(SiC), silicon nitride (Si3N4), titanium carbide and zirconium dioxide (zirconia).

[0060] In some cases, the filter material has an average melting point of at least about 150ºC. In use in an aerosol generating device, the filter is generally exposed to temperatures below 150ºC; thus, in such embodiments, the filter does not melt and supports the capsule well. This helps a user looking to crush a capsule after heating is started. In some cases, the filter material has an average melting point of at least about 160ºC, 170ºC, 180ºC, 190ºC or 200ºC.

[0061] In some cases, the filter material has an average thermal conductivity of at least 0.130 W / mK. The inventors have found that this helps the user looking to crush a capsule after heating is initiated. In some cases, the filter material has an average thermal conductivity of at least 0.140 W / mK, 0.150 W / mK or 0.160 W / mK.

[0062] In some cases, the filter may additionally comprise a housing that circumscribes the other components of the filter. The bark may comprise tobacco filter paper.

[0063] In some cases, the capsule fills about 5 to 30% v / v of the filter. In some cases, the filter comprises 70-95% v / v of filter material, suitably cellulose acetate. The inventors have established that these proportions result in the appropriate heat absorption by the capsule.

[0064] In some cases, the filter is substantially cylindrical and the capsule is arranged substantially in the center in relation to the diameter of the cylinder. In some cases, the capsule is arranged substantially centrally in relation to the length of the cylinder. In some cases, the cylindrical filter may be approximately 8-14 mm long, suitably 9-13 mm or 10-12 mm. It can have a cross-sectional diameter of approximately 5-9 mm, suitably 7.5-8 mm. It can be formed by cellulose acetate fibers.

[0065] In some cases, the pressure difference through the filter when the user inhales is in the range of 30 to 90 mmH2O, when the capsule is in an intact state. Suitably, the pressure difference through the filter can be in the range of about 30 mmH2O, 33 mmH2O, 35 mmH2O, 38 mmH2O or 40 mmH2O to about 90 mmH2O, 75 mmH2O, 65 mmH2O, 60 mmH2O, 55 mmH2O or 50 mmH2O or 50 mmH2O , when the capsule is in an intact state. Illustratively, the pressure difference through the filter, when the capsule is in an unbroken state, can be in the range of about 35-60 mmH2O, preferably 38-55 mmH2O or 40-50 mmH2O.

[0066] In some cases, the filter contains only one capsule. In other cases, the filter contains more than one capsule. When the filter comprises a plurality of capsules, the individual capsules may be the same or may be different. For example, a plurality of capsules can be provided so that the user can select when / if the capsule should be broken, thereby controlling the aerosol delivery profile.

[0067] In some cases, the aerosol generating means comprises an aerosol generating agent. In some cases, the aerosol generating means comprises a tobacco material. In some cases, the aerosol generating means comprises a flavoring. In some cases, the aerosol generating means substantially consists of or consists of an aerosol generating agent and / or a tobacco material and / or a flavoring. In some cases, the aerosol generating medium may be provided as a single unitary component. In other cases, the aerosol generating medium may comprise distinct sections containing different compositions. For example, the aerosol generating means may comprise an aerosol generating agent and a tobacco material and these may be provided in separate and separate sections of the aerosol generating means.

[0068] In some embodiments, the capsule contains a flavoring and the aerosol generating means comprises a flavoring, in which the flavoring in both cases is substantially the same. This can provide a more consistent scent profile. In some cases, the capsule contains menthol and the aerosol generating medium comprises menthol.

[0069] As used herein, the term "tobacco material" refers to any material comprising tobacco or derivatives thereof. The term "tobacco material" can include one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes. The tobacco material may comprise one or more of ground tobacco, tobacco fiber, cut tobacco, extruded tobacco, tobacco stalk, reconstituted tobacco and / or tobacco extract.

[0070] The tobacco used to produce tobacco material can be any suitable tobacco, such as simple grades or mixtures, cut or whole-leaf rags, including Virginia and / or Burley and / or Oriental. They can also be 'fine' tobacco particles or powder, expanded tobacco, stems, expanded stems and other processed stem materials, such as cut and laminated stems. The tobacco material can be ground tobacco or reconstituted tobacco material. The reconstituted tobacco material may comprise tobacco fibers and may be formed by molding, a Fourdrinier-based papermaking approach with subsequent addition of tobacco extract, or by extrusion.

[0071] As used in this document, the term "aerosol generating agent" refers to an agent that promotes the generation of an aerosol. An aerosol generating agent can promote the generation of an aerosol by promoting an initial vaporization and / or the condensation of a gas in a solid and / or liquid inhalable aerosol.

Suitable aerosol generating agents include, but are not limited to: a polyol, such as sorbitol, glycerol and glycols, such as propylene glycol or triethylene glycol; a non-polyol, such as monohydric alcohols, high boiling hydrocarbons, acids such as lactic acid, glycerol derivatives, esters, such as diacetin, triacetin, triethylene glycol diacetate, triethyl citrate or myristates, including ethyl myristate and isopropyl myristate and aliphatic esters of carboxylic acid, such as methyl stearate, dimethyl dodecanedioate and dimethyl tetradecanedioate. In some cases, the aerosol generating agent may comprise glycerol and / or propylene glycol.

[0073] In some cases, the aerosol generating means comprises at least 10% by weight of an aerosol generating agent based on the total weight of the aerosol generating means. Suitably, the aerosol generating means comprises at least 12%, 15%, 18% or 20% by weight of an aerosol generating agent based on the total weight of the aerosol generating means. The rest may, in some cases, be tobacco material.

[0074] In some cases, the heating article without burning can be substantially cylindrical.

[0075] In some cases, the heating item without burning may additionally comprise a cooling element. This can be arranged between the filter and the aerosol generating means, for example. The cooling element, if present, spans the filter from the hottest parts (in use) of the heating article without burning. The cooling element, if present, may comprise an empty tube, properly formed of paper. The vaporized components of the aerosol generating medium can condense to form an aerosol in use in the cooling element, if present.

[0076] The heating item without burning may additionally comprise ventilation openings. These can be provided on the side wall of the article. In some cases, ventilation openings may be provided in the filter and / or cooling element. These openings allow cold air to be drawn into the article during use, which mixes with the volatilized heated components, thereby cooling the aerosol.

[0077] Ventilation increases the generation of heated volatile components visible from the article when it is heated during use. The heated volatilized components are made visible by the cooling process of the heated volatilized components so that the heated volatilized components are oversaturated. The heated volatilized components then undergo droplet formation, also known as nucleation, and eventually the size of the aerosol particles in the heated volatilized components increases by further condensing the heated volatilized components and by coagulating newly formed droplets from the heated volatilized components.

[0078] In some cases, the proportion of cold air to the sum of the heated volatilized components and cold air, known as the proportion of ventilation, is at least 15%. A ventilation rate of 15% allows heated volatilized components to be made visible by the method described above. The visibility of the heated volatilized components allows the user to identify that the volatilized components were generated and adds to the sensory experience of the smoking experience.

[0079] In another example, the ventilation rate is between 50% and 85% to provide additional cooling for the volatilized heated components.

[0080] As used in this document, the term "unburned heating set" refers to the combination of an unburned heating article and a heater. The heater heats the aerosol generating means of the heating article without burning, without burning, to volatilize the components of the substrate and generate an inhalable vapor or aerosol.

[0081] In some cases, the heater may be supplied in its entirety with the article. For example, the heater can be a burnable fuel source that is attached to the article, so that, in use, the combustion of the fuel source heats the aerosol generating medium without burning that medium. In another example,

the heater may comprise a chemical heating source, such as a phase change material, which undergoes an exothermic reaction to produce heat, in use.

[0082] In other cases, the heater may be a separate object, configured for use with the article. For example, the heater can be a device in which the heating article without burning is at least partially inserted. In another example, the heater can be a device that is at least partially inserted into the heating article without burning. The heater can be controlled electrically. In some cases, the heater comprises a thin film, electrically resistive heater, an induction heater or the like.

[0083] In some cases, the assembly can be configured in such a way that at least a portion of the aerosol generating medium in the heating article without burning is exposed to a temperature of at least 180ºC or 200ºC during at least 50% of the heating period heating. In some examples, the aerosol generating medium may be exposed to a heat profile, as described in the co-pending application PCT / EP2017 / 068804, the contents of which are incorporated in this document in its entirety.

[0084] In some particular cases, a non-burning heating kit is provided, which is configured to heat two portions of the aerosol generating medium separately. By controlling the temperature of the first and second portions over time, so that the temperature profiles of the portions are different, it is possible to control the aerosol blowing profile during use. The heat supplied to the two portions of the aerosol generating medium can be supplied at different times or rates; staggering the heating in this way can allow for rapid aerosol production and longevity of use.

[0085] In a particular example, the assembly can be configured so that at the beginning of the consumption experiment, a first heating element corresponding to a first portion of the aerosol generating medium is immediately heated to a temperature of 240 ° C. This first heating element is kept at 240 ° C for 145 seconds and then drops to 135 ° C (where it remains for the rest of the consumption experience). 75 seconds after the start of the consumption experiment, a second heating element corresponding to a second portion of the aerosol generating medium is heated to a temperature of 160 ° C. 135 seconds after the start of the consumption experiment, the temperature of the second heating element is raised to 240 ° C (where it remains for the rest of the consumption experiment). The consumption experience lasts 280 seconds, when both heaters are cooled to room temperature.

[0086] In some cases, the set is configured in such a way that the filter of the heating article without burning is not directly heated. For example, in cases where the heater is a device in which the article is partially inserted, the assembly can be configured so that the filter of the heating article without burning is not inserted into the device.

[0087] In some particular cases, the set is configured so that the filter and, if present, the cooling element of the heating article without burning, are not directly heated. For example, in cases where the heater is a device in which the article is partially inserted, the assembly can be configured so that the filter and, if present, the cooling element of the heating article without burning are not inserted into the device. . In other cases, at least part of the cooling element can be inserted into the device.

[0088] In such cases, even if the filter is not subject to direct heating, the heat will be sucked through the heating article without burning during the consumption experience (when the user brings it). The inventors have established that the temperature profile of the center of the filter reaches its peak at the time of each puff. This is due to the hot aerosol being sucked through the filter during the swallow. In some cases, the filter (and the capsule) may be exposed to a temperature in excess of about 30ºC, 40ºC or 50ºC during use. In some cases, the maximum temperature to which the filter (and the capsule) is exposed in use is less than about 100ºC, 90ºC, 80ºC or 70ºC. In some cases, the filter (and the capsule) can be exposed to temperatures in the range of 30ºC – 100ºC, suitably 40ºC-80ºC or 50ºC-70ºC.

[0089] The inventors have established that the capsules stipulated in claim 1 are particularly suitable for use in a non-burning heating article. Even though the capsules may, in some cases, be exposed to a temperature that exceeds the melting point of the shell or the glass transition temperature, the capsules stipulated in claim 1 are less likely to fail or break under exposure to conditions in a set heating without burning when compared to other capsules. These capsules can be easily crushed by the user before, during or after heating has started to release their contents. A feeling of clicking on the crush is maintained, providing tactile perception to the user that the crush has been performed. This click sensation is useful, since the user knows that enough pressure has been applied and the contents of the capsule have been released. Excess pressure, which can damage the heating article without burning, is therefore less likely to be applied.

[0090] Without wishing to be limited by theory, the suitability of the capsules described here for use in a non-burning heating article is thought to be associated with the composition of the shell material and water absorption. Other factors that may be relevant include the heating capacity of the shell material, the melting point or the glass transition temperature of the coating material, and / or the distance of the capsule from the heater.

[0091] In some cases, the capsule can be disposed within the heating article without burning so that it is at least about 25 mm or at least about 30 mm from the heater in the non-burning heating set. In some cases, the capsule may be arranged inside the heating article without burning so that it is about 25-30 mm or about 30-35 mm from the heater. (These distances refer to the distance from the center of the capsule to the point closest to the heater). This positioning can mean that the capsule is exposed to an appropriate heating level, while ensuring that the heating item without burning has the appropriate dimensions.

[0092] Capsules formed from a wrapping material comprising a carrageenan with a melting point of at least 30 ° C or at least 40 ° C survive very well the exposure to heating conditions without burning.

[0093] An example of an unburned heating article is shown in Figure 1. The illustrated unburned heating article 10 has a substantially cylindrical shape. It may include an aerosol generating medium bar 1, suitably a tobacco material bar, towards a first end 2 and a filter 3 towards the second end 4. The second end 4 is a mouth end. A capsule 5 is disposed within the filter 3. The filter 3 comprises a filter material which can be cellulose acetate. A paper sheath 6 holds the components in the cylindrical configuration and provides a passage 7 between the tobacco rod 1 and the filter plug 3. The passage 7 acts as a cooling element and can be omitted in alternative embodiments. Another short passage is shown between the filter plug 3 and the second end 4. This can also be omitted in alternative embodiments.

[0094] In use, the unburned heating article 10 is partially inserted into an unburned heating assembly (not shown) so that it can be heated from an inhalable aerosol. In one embodiment, the heater forms an oven-like arrangement around the aerosol generating means. In some embodiments, the first end 2 of the non-burning heating article 10 is inserted, so that the aerosol generating means 1 is contained within the heater. The unburned heating article 10 and the unburned heating assembly are configured in such a way that the filter 3 and at least some of the passage 7 is not in the heater.

[0095] In alternative embodiments, the substantially cylindrical heating article without burning may include the aerosol generating medium 1 immediately adjacent to the filter

3. A passage can be provided on the opposite side of the filter to the middle, or there may be no passage.

[0096] After use, the heating item without burning is removed from the heater and normally discarded. Subsequent uses of the heater use other heating articles without burning.

[0097] An alternative unburned heating set is shown in Figure 2. In this set, a combustible heating source 8 is arranged adjacent to the aerosol generating means 1 at the first end 2 of the unburned heating article 10. The heating source fuel 8 can be separated from the aerosol generating means 1 by a non-combustible material (not shown), such as a layer of aluminum foil. Aluminum foil or other non-combustible conductive materials are useful because (a) they conduct heat to the aerosol generating medium and (b) prevent combustion of the fuel source resulting in combustion of the aerosol generating medium. In use, fuel source 8 is ignited by the user; heat is conducted by the aluminum foil (or similar) to the aerosol generating medium 1, to volatilize the components of medium 1 without combustion.

[0098] With reference to Figures 3 and 4, a partially cross-sectional view and a perspective view of an example of an unburned heating article 101, similar to that shown in Figure 1, are shown. Article 101 is adapted for use with a device that has a power source and a heater. Article 101 of this embodiment is particularly suitable for use with device 51 shown in Figures 7 to 9, described below. In use, article 101 can be removably inserted into the device shown in Figure 7 at an insertion point 20 of device 51.

[0099] The article 101 of an example is in the form of a substantially cylindrical bar that includes an aerosol generating means body 103 and a filter assembly 105 in the form of a bar. The filter assembly 105 includes three segments, a cooling segment 107, a filter segment 109 and a mouth end segment 111. Article 101 has a first end 113, also known as a mouth or proximal end and a second end 115, also known as the distal end. The body of the aerosol generating means 103 is located towards the distal end 115 of the article

101. In one example, cooling segment 107 is located adjacent to the aerosol generating means body 103 between the aerosol generating means body 103 and filter segment 109, so that cooling segment 107 is in a relationship adjacent with the aerosol generating means 103 and the filter segment 103. In other examples, there may be a separation between the aerosol generating means body 103 and the cooling segment 107 and between the aerosol generating means body 103 and the filter segment 109. Filter segment 109 is located between the cooling segment 107 and the mouth end segment 111. The mouth end segment 111 is located towards the proximal end 113 of article 101, adjacent to the end segment filter 109. In one example, filter segment 109 is in a containment relationship with mouth end segment 111. In one embodiment, the total length of filter assembly 105 is between 37 mm and 45 mm mm, more preferably, the total length of the filter assembly 105 is 41 mm.

[0100] In one embodiment, the aerosol generating means body 103 comprises tobacco. However, in other respective embodiments, the body of the aerosol generating means 103 may consist of tobacco, may consist substantially entirely of tobacco, may comprise tobacco and other components, such as an aerosol-generating and / or flavoring agent. In some cases, the aerosol generating medium may be tobacco free.

[0101] In one example, the rod of the aerosol generating means 103 is between 34 mm and 50 mm in length, suitably between 38 mm and 46 mm in length, suitably 42 mm in length.

[0102] In one example, the total length of article 101 is between 71 mm and 95 mm, suitably between 79 mm and 87 mm, suitably 83 mm.

[0103] An axial end of the body of the aerosol generating means 103 is visible at the distal end 115 of the article 101. However, in other embodiments, the distal end 115 of the article 101 may comprise an end member (not shown) covering the axial end of the body of the aerosol generating means 103.

[0104] The body of the aerosol generating means 103 is joined to the filter assembly 105 by ring filter paper (not shown), which is located substantially around the circumference of the filter assembly 105 to surround the filter assembly 105 and extends partially along the length of the body of aerosol generating means 103. In one example, the filter paper is made of standard 58GSM filter paper. In one example, the filter paper is between 42 mm and 50 mm in length, suitably 46 mm.

[0105] In one example, the cooling segment 107 is an annular tube and is located around and defines an air gap within the cooling segment. The air gap provides a chamber for the heated volatilized components generated from the body of the aerosol generating means 103 to flow. Cooling segment 107 is hollow to provide an aerosol accumulation chamber, but rigid enough to withstand axial compression forces and bending moments that may arise during manufacture and while article 101 is in use during insertion into the device 51 In one example, the wall thickness of cooling segment 107 is approximately 0.29 mm.

[0106] Cooling segment 107 provides a physical displacement between aerosol generating means 103 and filter segment 109. The physical displacement provided by cooling segment 107 will provide a thermal gradient along the length of cooling segment 107. In For example, cooling segment 107 is configured to provide a temperature differential of at least 40 degrees Celsius between a heated volatilized component that enters a first end of the cooling segment 107 and a volatilized heated component that exits a second end of the cooling segment 107. In one example, cooling segment 107 is configured to provide a temperature differential of at least 60 degrees Celsius between a heated volatilized component that enters a first end of the cooling segment 107 and a heated volatilized component that exits a second end of the cooling segment 107. This d temperature difference along the length of the cooling segment 107 protects the temperature sensitive filter segment 109 from the high temperatures of the aerosol generating medium 103 when it is heated by the device 51. If physical displacement has not been provided between the cooling segment filter 109 and the body of the aerosol generating means 103 and the heating elements of the device 51, then the temperature sensitive filter segment 109 can be damaged in use, so that it would not perform its necessary functions as effectively.

[0107] 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 particularly 23 mm to 27 mm, more particularly 25 mm to 27 mm, suitably 25 mm.

[0108] Cooling segment 107 is made of paper, which means that it is composed of a material that does not generate compounds of concern, for example, toxic compounds when in use adjacent to the heater of device 51. In one example, the segment cooling unit 107 is manufactured from a spiral-wound paper tube that provides a hollow inner chamber, but maintains mechanical rigidity. Spiral-wrapped paper tubes are capable of meeting the strict requirements for dimensional accuracy of high-speed manufacturing processes with respect to tube length, outside diameter, circularity and linearity.

[0109] In another example, cooling segment 107 is a recess created from a hard plug or filter paper wrapper. The hard plug or filter paper wrapper is manufactured to have a stiffness that is sufficient to withstand the axial compression forces and bending moments that may arise during manufacture and while the article 101 is in use during insertion into the device 51 .

[0110] Filter segment 109 may be formed from any filter material sufficient to remove one or more volatilized compounds from heated volatilized components of the aerosol generating means. In one example, filter segment 109 is made of a monoacetate material, such as cellulose acetate. Filter segment 109 provides cooling and irritation reduction of heated volatilized components without exhausting the amount of heated volatilized components to an unsatisfactory level for a user.

[0111] A crushable capsule 5 is provided in filter segment 109. It can be arranged substantially centrally in filter segment 109, both through the diameter of filter segment 109 and along the length of filter segment 109. In other cases , can be moved in one or more dimensions.

[0112] The density of the cellulose acetate tow material of the filter segment 109 controls the pressure drop through the filter segment 109, which in turn controls the tensile strength of article 101. Therefore, the selection of the material of the filter segment 109 is important in controlling the suction resistance of article 101. In addition, the filter segment performs a filtration function on article 101.

[0113] In one example, filter segment 109 is made of grade 8Y15 filter trailer material, which provides a filtering effect on the heated volatilized material, while also reducing the size of the condensed aerosol droplets that result from the material volatilized heated.

[0114] The presence of 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.

[0115] In one example, filter segment 109 is between 6 mm to 10 mm long, suitably 8 mm.

[0116] The mouth end segment 111 is an annular tube and is located around and defines an air gap within the mouth end segment 111. The air gap provides a chamber for heated volatilized components flowing from the end segment. filter 109. The mouth end segment 111 is hollow to provide an aerosol accumulation chamber, but rigid enough to withstand axial compression forces and bending moments that may arise during manufacture and while the article is in use during insertion into the device

51. In one example, the wall thickness 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 to 10 mm, suitably 8 mm.

[0117] The mouth end segment 111 can be manufactured from a spiral-wound paper tube that provides a hollow inner chamber, but maintains critical mechanical rigidity. Spiral-wrapped paper tubes are capable of meeting the strict requirements for dimensional accuracy of high-speed manufacturing processes with respect to tube length, outside diameter, circularity and linearity.

[0118] The mouth end segment 111 provides the function of preventing any condensed liquid from accumulating at the outlet of the filter segment 109 from coming into direct contact with a user.

[0119] It should be appreciated that, in one example, the mouth end segment 111 and the cooling segment 107 can be formed by a single tube and the filter segment 109 is located within that tube separating the mouth end segment 111 and the cooling segment 107.

[0120] With reference to Figures 5 and 6, a partially cut section is shown and seen in perspective of an example of an article 301. The reference signs shown in Figures 5 and 6 are equivalent to the reference signs shown in Figures 3 and 4, but with an increase of 200.

[0121] In the example of article 301 shown in Figures 5 and 6, a ventilation region 317 is provided in article 301 to allow air to flow into article 301 from outside article 301. In one example, the ventilation region 317 takes the form of one or more ventilation holes 317 formed through the outer layer of article 301. The ventilation holes can be located in cooling segment 307 to assist in cooling article 301. In one example, the region ventilation shaft 317 comprises one or more rows of orifices and preferably each row of orifices is circumferentially arranged around the article 301 in a cross section that is substantially perpendicular to a longitudinal axis of the article 301.

[0122] In one example, there are between one to four rows of ventilation holes to provide ventilation for the article

301. Each row of ventilation holes can have between 12 to 36 ventilation holes 317. Ventilation holes 317 can, for example, be between 100 to 500 µm in diameter. In one example, an axial separation between rows of ventilation holes 317 is between 0.25 mm and 0.75 mm, suitably 0.5 mm.

[0123] In one example, the ventilation holes 317 are of uniform size. In another example, the ventilation holes 317 vary in size. The ventilation holes can be made using any suitable technique, for example, one or more of the following techniques: laser technology, mechanical drilling of the cooling segment 307 or pre-drilling of the cooling segment 307 before being formed in article 301. The ventilation holes 317 are positioned to provide effective cooling to the article 301.

[0124] In one example, the rows of ventilation holes 317 are located at least 11 mm from the proximal end 313 of the article, suitably between 17 mm and 20 mm from the proximal end 313 of the article 301. The location of the ventilation holes 317 it is positioned so that the user does not block ventilation holes 317 when article 301 is in use.

[0125] Supplying the rows of ventilation holes between 17 mm and 20 mm from the proximal end 313 of article 301 allows ventilation holes 317 to be located outside device 51, when article 301 is fully inserted into device 51, as can be seen in Figures 8 and

9. When locating the ventilation holes outside the device, unheated air is able to enter the article 301 through the ventilation holes outside the device 51 to assist in cooling the article 301.

[0126] The length of the cooling segment 307 is such that the cooling segment 307 will be partially inserted in the device 51, when the article 301 is fully inserted in the device 51. The length of the cooling segment 307 provides a first function of providing a physical opening between the heater arrangement of the device 51 and the heat sensitive filter arrangement 309 and a second function of allowing the ventilation holes 317 to be located in the cooling segment, although it is also located outside the device 51, when the article 301 is fully inserted into device 51. As can be seen in Figures 8 and 9, most of the cooling element 307 is located within device 51. However, there is a portion of the cooling element 307 that extends outside the device 51. It is in this portion of the cooling element 307 that extends outside the device 51 in which the ventilation holes 317 are located. localized.

[0127] Referring now to Figures 7 to 9 in more detail, an example of a device 51 arranged to heat aerosol generating means to volatilize at least one component of said aerosol generating means is shown, typically to form an aerosol that can be inhaled. Device 51 is a heating device that releases compounds by heating, but not burning, the aerosol generating means.

[0128] A first end 53 is sometimes referred to here as the proximal or mouth end 53 of the device 51 and a second end 55 is sometimes referred to here as the distal end 55 of the device 51. The device 51 has an on / off button turns off 57 to allow device 51 as a whole to be turned on and off as desired by the user.

[0129] Device 51 comprises a housing 59 to locate and protect various internal components of the device

51. In the example shown, the housing 59 comprises a single-body sleeve 11 covering the perimeter of the device 51, capped with an upper panel 17 that generally defines the "top" of the device 51 and a lower panel 19 that generally defines the ' bottom 'of the device 51. In another example, the housing comprises a front panel, a rear panel and a pair of opposite side panels, in addition to the top panel 17 and the bottom panel 19.

[0130] The top panel 17 and / or the bottom panel 19 can be removably attached to the single body sleeve 11, to allow easy access to the interior of the device 51, or they can be "permanently" attached to the single body sleeve 11 , for example, to prevent a user from accessing the interior of device 51. In one example, panels 17 and 19 are made of a plastic material, including, for example, glass-filled nylon formed by injection molding, and the sleeve single-body 11 is made of aluminum, although other materials and other manufacturing processes can be used.

[0131] The upper panel 17 of the device 51 has an opening 20 at the mouth end 53 of the device 51 through which, in use, the article 101, 301 including the aerosol generating means can be inserted into the device 51 and removed from the device 51 by a user.

[0132] Enclosure 59 has a heater arrangement 23, control circuit 25 and a power source located or attached to it

27. In this example, heater arrangement 23, control circuit 25 and power source 27 are laterally adjacent (ie, adjacent when viewed from one end), with control circuit 25 generally located between the arrangement of heater 23 and power source 27, although other locations are possible.

[0133] Control circuits 25 may include a controller, such as a microprocessor arrangement, configured and arranged to control the heating of the aerosol generating means in article 101, 301 as discussed further below.

[0134] Power source 27 can be, for example, a battery, which can be a rechargeable battery or a non-rechargeable battery. Examples of suitable batteries include, for example, a lithium ion battery, a nickel battery (such as a nickel-cadmium battery), an alkaline battery and / or the like. The battery 27 is electrically coupled to the heater arrangement 23 to supply electrical power when necessary and under control of the control circuits 25 to heat the aerosol generating medium in the article (as discussed, to volatilize the aerosol generating medium without causing the burning of the aerosol). aerosol generating medium).

[0135] An advantage of locating the power source 27 laterally adjacent to the heater arrangement 23 is that a physically large power source 25 can be used without causing the device 51 as a whole to be unduly long. As will generally be understood, a physically large power source 25 has a greater capacity (that is, the total electrical energy that can be supplied, often measured in ampere-hours or the like) and therefore the battery life for device 51 may be longer.

[0136] In one example, heater arrangement 23 is generally in the form of a hollow cylindrical tube, containing a hollow internal heating chamber 29 in which article 101, 301 comprising the aerosol generating means is inserted for heating in use. Different arrangements for heater arrangement 23 are possible. For example, heater arrangement 23 may comprise a single heating element or may be formed by several heating elements aligned along the longitudinal axis of heater arrangement 23. The single or each heating element may be ring or tubular, or at least partially annular or partially tubular around its circumference. In one example, the single or each heating element may be a thin film heater. In another example, the heating element itself or each element may be made of a ceramic material. Examples of suitable ceramic materials include alumina and aluminum nitride and silicon nitride ceramics, which can be laminated and sintered.

Other heating arrangements are possible, including, for example, inductive heating, infrared heating elements, which heat by emitting infrared radiation, or resistive heating elements formed by, for example, a resistive electrical winding.

[0137] In a particular example, heater arrangement 23 is supported by a stainless steel support tube and comprises a polyimide heating element. The heater arrangement 23 is dimensioned so that substantially the entire body of the aerosol generating means 103, 303 of article 101, 301 is inserted into the heater arrangement 23 when the article 101, 301 is inserted into the device 51.

[0138] The single or each heating element can be arranged so that the selected zones of the aerosol generating medium can be heated independently, for example, in turn (over time, as discussed above) or together (simultaneously) , as desired.

[0139] The heater arrangement 23 in this example is surrounded along at least part of its length by a thermal insulator 31. The insulator 31 helps to reduce the heating passage from the heater arrangement 23 to the outside of the device 51. This helps to keep energy requirements low for heater arrangement 23 as it reduces overall heat losses. The insulator 31 also helps to keep the exterior of the device 51 cool during the operation of the heater arrangement 23. In one example, the insulator 31 can be a double wall sleeve that provides a low pressure region between the two walls of the sleeve. That is, the insulator 31 can be, for example, a "vacuum" tube, that is, a tube that has been at least partially evacuated in order to minimize the transfer of heat by conduction and / or convection. Other arrangements for insulator 31 are possible, including the use of heat insulating materials, including, for example, a foam material of the appropriate type, in addition to or instead of a double wall sleeve.

[0140] The housing 59 may also comprise several internal support structures 37 to support all internal components, as well as the heating arrangement 23.

[0141] The device 51 also comprises a collar 33 that extends around and protrudes from the opening 20 into the housing 59 and a generally tubular chamber 35 that is located between the collar 33 and one end of the vacuum sleeve

31. Chamber 35 also comprises a cooling structure 35f, which in this example comprises a plurality of cooling fins 35f spaced along the outer surface of chamber 35, and each disposed circumferentially around the outer surface of chamber 35. There is an air gap 36 between the hollow chamber 35 and the article 101, 301 when it is inserted into the device 51 along at least part of the length of the hollow chamber 35. The air gap 36 is around the entire circumference of the article 101 .301 over at least part of the cooling segment 307.

[0142] The collar 33 comprises a plurality of ridges 60 arranged circumferentially around the periphery of the opening 20 and projecting towards the opening 20. The ridges 60 occupy space within the opening 20 so that the open span of the opening 20 at the locations the ridges 60 are smaller than the open span of the opening 20 in places without the ridges 60. The ridges 60 are configured to fit with an article 101, 301 inserted in the device to help secure it within the device 51. Open spaces (not shown in the Figures) defined by pairs of adjacent ridges 60 and article 101, 301 form ventilation paths around the outside of article 101, 301. These ventilation paths allow hot vapors to escape from article 101, 301 to exit the device 51 and allow the cooling air to flow to device 51 around article 101, 301 in the air gap 36.

[0143] In operation, article 101, 301 is removably inserted at an insertion point 20 of device 51, as shown in Figures 7 to 9. With particular reference to Figure 8, in one example, the body of the generating means aerosol dispenser 103, 303, which is located towards the distal end 115, 315 of article 101, 301, is entirely received within the heater arrangement 23 of device 51. The proximal end 113, 313 of article 101, 301 extends to from device 51 and acts as a nozzle set for a user.

[0144] In operation, heater arrangement 23 will heat article 101, 301 to volatilize at least one component of the aerosol generating means of the body of the aerosol generating means 103, 303.

[0145] The primary flow path for the heated volatilized components of the body of the aerosol generating means 103, 303 is axially through the article 101, 301, through the chamber within the cooling segment 107, 307, through the filter segment 109 , 309, through the mouth end segment 111, 313 for the user. In one example, the temperature of the heated volatilized components that are generated from the body of the aerosol generating medium is between 60 ° C and 250 ° C,

which may be above the user's acceptable inhalation temperature. As the heated volatilized component travels through the cooling segment 107, 307, it will cool and some volatilized components will condense on the internal surface of the cooling segment 107, 307.

[0146] In the examples in article 301 shown in Figures 5 and 6, cold air will be able to enter the cooling segment 307 through the ventilation holes 317 formed in the cooling segment 307. This cold air will mix with the volatilized components heated to provide cooling for the heated volatilized components.

[0147] Ventilation increases the generation of heated volatilized components visible from article 317 when it is heated in use by device 51. The heated volatilized components are made visible by the cooling process of the heated volatilized components so that the volatilized components are supersaturated. heated. The heated volatilized components then undergo droplet formation, also known as nucleation, and eventually the size of the aerosol particles in the heated volatilized components increases by further condensing the heated volatilized components and by coagulating newly formed droplets from the heated volatilized components.

[0148] In one embodiment, the ratio of cold air to the sum of the heated volatilized components and cold air, known as the ventilation rate, is at least 15%. A ventilation rate of 15% allows heated volatilized components to be made visible by the method described above. The visibility of heated volatilized components allows the user to identify that the volatilized components were generated and adds to the sensory experience of the smoking experience.

[0149] In another example, the ventilation rate is between 50% and 85% to provide additional cooling for the volatilized heated components.

[0150] As used in this document, the terms "aroma" and "flavoring" refer to materials that, where local regulations permit, can be used to create a desired flavor or aroma in a product for adult consumers. They can include extracts (for example, licorice, hydrangea, white-skinned Japanese magnolia leaf, chamomile, fenugreek, cloves, menthol, Japanese mint, anise, cinnamon, herb, wintergreen, cherry, berry, peach, apple, Drambuie , bourbon, scotch whiskey, whiskey, mint, peppermint, lavender, cardamom, celery, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, cassia, cumin, cognac, jasmine, ylang-ylang, sage, fennel, pepper, ginger, fennel, coriander, coffee or a mint oil of any species of the genus Mentha), flavor enhancers, receptor site blockers bitterness, activators or stimulators of the sensory receptor site, sugars and / or sugar substitutes (for example, sucralose, acesulfame potassium, aspartame, saccharin, cyclamates, lactose, sucrose, glucose, fructose, sorbitol or mannitol) and other additives, such as coal, chlorophyll, minerals, botanicals or cooling agents breath breathers. They can be imitation, synthetic or natural ingredients or mixtures of them. They can be in any suitable form, for example, oil, liquid or powder.
