Description

The field of technology

This invention relates to a product and a node.

Prerequisites of the invention

In products such as cigarettes, cigars, etc., tobacco is burned during use to produce tobacco smoke. Alternative versions of these combustible products generate an inhalable aerosol by heating the substrate material.

These products may be commonly referred to as aerosol generating devices. An example of such aerosol generating devices are so-called heat-but-not-burn products, also known as tobacco heating products or tobacco heating devices, which release compounds by heating, rather than burning, a solid substrate material to form an aerosol , which is inhaled. The material can be, for example, tobacco, or other non-tobacco products, or a combination, such as a ready-made mixture, which may or may not contain nicotine.

Detailed description of the invention

According to a first aspect of the present invention, there is provided a heating but non-burning article comprising an aerosol generating medium and a filter, wherein the filter contains one or more fragile capsules, wherein in use the aerosol generating medium is heated without incineration, and the capsule is exposed to a temperature of approximately 30-1002C, while its structural integrity is not disturbed during this exposure, so that the capsule can be crushed by the user before, during or after heating.

An aerosol generated by a product that is heated but not burned is typically warm and moist due to the properties of the heating profile and the composition of the aerosol generating medium. For example, an aerosol-generating medium in a heating but not burning product of the present invention may contain a greater proportion of the aerosol-generating agent than the smoking material used in the combustible product. Additionally or alternatively, the aerosol generating medium in the heated but not burned product of the present invention may be heated to a higher temperature and/or for a longer period of time than the burning temperature/period of the combustible product.

The authors of this invention found that the capsules, described in detail in clause 1 of the claims, are particularly suitable for use in a product that heats, but does not burn, and its conditions. It turned out that the capsules defined in clause 1 of the claims of the invention are less likely to be destroyed or cracked under the influence of conditions in the product that heats, but does not burn, compared to other capsules.

In some cases, during use, the aerosol generating medium generates a wet 60 aerosol and the capsule is exposed to at least 12 mg of water.

The authors of this invention have determined that the temperature profile of the center of the filter reaches a maximum during each puff during use. This is due to the hot aerosol that is drawn in through the filter during puffing. In some cases, the capsule may be exposed to temperatures greater than about 309C, 409C or 509C during use. In some cases, the maximum temperature to which the capsule is exposed during use is less than about 1009C, 909C, 809C, or 709C. In some cases, the capsule may be exposed to temperatures in the range of 309C to 1009C, 402C to 802C, or 502C to 7096C, respectively.

In the context of this document, the term "heating but not burning product" refers to a product containing an aerosol generating medium; during use, the components of the aerosol-generating medium are vaporized by heating without combustion/combustion to form an inhalable vapor or aerosol.

The aerosol-generating medium of a product that heats but does not burn contains a solid component (as opposed to the aerosol-generating medium of electronic cigarettes, in which the aerosol-generating medium is liquid). By "solid" it is meant that the environment that generates the aerosol is not characterized by a liquid state in a steady state.

The term "solid" may include gels and the like. For the avoidance of doubt, the aerosol generating medium of a heating but not burning product may contain, in addition to a solid component, a liquid component.

The capsule described herein may have a core-shell structure. In such cases, the core contains liquid. In some cases, the core may contain one or more aerosol generating agents and/or one or more flavoring agents. In some cases, the core may contain an acid, a base, and/or water. In some cases, the core may contain a solvent. In some specific cases, the core may contain menthol.

The capsule shell material (which may alternatively be referred to herein as the barrier material or the encapsulating material) encapsulates the core. The shell material may, in some cases, function to minimize core migration during product storage. In some cases, the shell material may provide a controlled release of the core during use. The capsule may crack (i.e. be

With crushed) to release elements of the content before, during or after the heating of a product that heats but does not burn.

The capsule shell material is fragile; that is, it is brittle or fragile. The capsule is crushed or otherwise cracked or broken by the user to release the contents. Typically, the capsule breaks immediately before heating is initiated, but the user can choose when to release the contents (ie, it can be crushed after heating is initiated). The term "fragile capsule" refers to a capsule in which the encapsulating material (which may be the shell) can be broken by pressure to release the encapsulated material (which may be the core of the capsule); more specifically, the encapsulating material (eg, a shell) can crack under pressure applied by the user's fingers (or any other means of applying pressure) when the user wants to release the elements of the capsule. In some cases, the capsule may have an initial crush strength (before heating) of from about 7.845 N to about 34.323 N, respectively from about 9.806 N to about 24.517 N, or from about 9.806 to about 19.613 N. The inventors of the present invention have determined that the capsules can be weakened during heating. The present inventors have found that capsules having an initial crush strength of at least 7.845 N are less likely to break/crack when heated. The present inventors have found that capsules having a crush strength greater than 34,323 N are difficult to crush before heating. The authors of this invention determined that the initial crushing strength in the range from 9.806 N to 24.517

H provides the greatest effectiveness of the capsule.

In some cases, the capsules described herein may 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 capsule may be less than about 10.0 mm, 8.0 mm, 7.0 mm, 6.0 mm, 5.5

MM, 5.0mm, 4.5mm, 4.0mm, 3.5mm or 3.2mm. By way of illustration, the diameter of the capsule can range from 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 may have a diameter of from about 3.0 mm to about 3.5 mm. These dimensions are particularly suitable for incorporating a capsule into a filter for a product that heats but does not burn. 60 In some cases, the total weight of a capsule described herein may range from 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.

In some cases, the total weight of the core composition may range from 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.

The shell contains 5-90 95 by weight, based on the total weight of the capsule shell, of a gel forming agent, wherein the gel forming agent contains, consists essentially of, or consists of carrageenan. In some cases, the shell contains 5-60 95, 5-50 95 or 10-35 95 by weight, based on the total weight of the capsule shell, of the specified gelling agent. In some cases, the gelling agent in the capsule shell contains carrageenan. In some cases, the carrageenan has a melting point of at least about 302C or at least about 402C.

In addition to carrageenan, the shell may contain additional gelling agents.

Suitable gelling agents that may be included in the capsule shell material may include, without limitation, polysaccharide or cellulosic gelling agents, gelatins, gum types, gels, waxes, or mixtures thereof. Suitable polysaccharides include alginates, dextrans, maltodextrins, cyclodextrins and pectins. Suitable alginates include, for example, alginic acid salt, esterified alginate or glyceryl alginate. Salts of alginic acid include salts based on ammonium alginate, triethanolamine alginate and metal ion alginate | and II groups, such as alginate sodium, potassium, calcium and magnesium.

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 methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose, cellulose acetate and cellulose ethers. The gelling agent may contain one or more types of modified starch. The gelling agent may contain one or more carrageenans. Suitable gum types include agar, gellan gum, arabic gum, pullulan gum, mannan gum, ghatti gum,

From gum tragacanth, caraway gum, locust bean gum, gum arabic, guar gum, quince gum and xanthan gum. Suitable gels include agar, agarose, carrageenan, furoidan and furcellaran. Suitable waxes include carnauba wax. In some cases, the gelling agent may contain carrageenans and/or gellan gum; these gelling agents are particularly suitable for inclusion as a gelling agent as the pressure required to break the resulting capsules is particularly suitable. In some cases, the capsule shell does not contain gelatin.

The capsule shell may additionally contain one or more of a disintegrant, a buffer, a colorant, and a plasticizer.

In some cases, the capsule shell material may contain one or more disintegrants such as starches, modified starches (such as oxidized starches), and sugar alcohols such as maltitol.

In some cases, the capsule shell material may contain a dye that facilitates the location of the capsule within the tobacco product during manufacture. The dye is preferably selected from coloring agents and pigments.

In some cases, the capsule shell material may additionally contain at least one buffer, such as a citrate or phosphate compound.

In some cases, the capsule shell material may additionally contain at least one plasticizer, which may be glycerin, sorbitol, maltitol, triacetin, polyethylene glycol, propylene glycol, or another polyalcohol with plasticizing properties, and optionally one acid of the monoacid, diacid, or triacid type, especially citric acid, fumaric acid, malic acid, etc. In some cases, the amount of plasticizer is in the range from 1 95 to 30 95 by weight, preferably from 2 95 to 15 95 by weight, and even more preferably from 3 to 10 95 by weight of the total weight of the shell. In some cases, the total amount in the shell of the plasticizer together with the gelling agent is about 40-70 95, respectively 50-- 95 bO by weight, based on the total weight of the capsule shell. In some cases, the plasticizer contains, essentially consists of, or consists of glycerin.

In some cases, the capsule shell may also contain one or more fillers.

Suitable excipients include starch derivatives such as dextrin, maltodextrin, 60 cyclodextrin (alpha, beta or gamma) or cellulose derivatives such as hydroxypropylmethylcellulose (HPMC), hydroxypropylcellulose (HPC), methylcellulose (MC), carboxymethylcellulose (CMS), polyvinyl alcohol, polyhydric alcohols or their mixture.

The capsule shell may contain, in some cases, no more than about 60 95 by weight of aggregate, based on the total weight of the capsule shell. In some cases, the capsule shell may contain no more than about 50 95, 40 95, 30 95, or 20 95 by weight of aggregate, based on the total weight of the capsule shell. In some specific cases, the capsule shell may not contain a filler.

The capsule shell may additionally contain a hydrophobic outer layer that reduces the susceptibility of the capsule to degradation due to humidity. The hydrophobic outer layer is suitably selected from the group containing waxes, especially carnauba wax, candelilla wax or beeswax, carbowax, shellac (in alcoholic or aqueous solution), ethyl cellulose, hydroxypropyl methyl cellulose, hydroxypropyl cellulose, latex composition, polyvinyl alcohol or a combination thereof. More preferably, at least one waterproofing agent is ethyl cellulose or a mixture of ethyl cellulose and shellac.

Methods of creating a capsule include coextrusion, which is optionally accompanied by centrifugation and solidification and/or drying. These and other suitable techniques are known in the art.

The filter may contain filter material. For example, the filter may contain a cellulosic material such as cellulose acetate, a ceramic material, polylactic acid, a polymer matrix, and/or activated carbon. Suitable examples of ceramic materials include silicon carbide (SiC), silicon nitride (SiNi), titanium carbide and zirconium dioxide (zirconia).

In some cases, the filter material has an average melting point of at least about 1502C. When used in an aerosol generating device, the filter is typically exposed to temperatures below 150°C; thus, in such embodiments, the filter does not melt and supports the capsule well. This helps the user who tends to crush the capsule after the heating is initiated. In a particular case, the filter material has an average melting point of at least about 1602, 1709, 1809C, 19022, or 200960.

In some cases, the filter material has an average thermal conductivity of at least 0.130 W/meK. The inventors of the present invention have found that this helps the user who tends to crush the capsule after the heating is initiated. In some cases, the filter material has an average thermal conductivity of at least 0.140 W/meK, 0.150 W/meK, or 0.160 W/meK.

In some cases, the filter may further include a wrap that surrounds other filter components. The wrapper may contain tobacco rim paper.

In some cases, the capsule fills approximately 5-30 95 of the total volume of the filter. In some cases, the 70-95595 filter contains a filter material, suitably cellulose acetate. The authors of this invention have established that these particles lead to proper absorption of heat by the capsule.

In some cases, the filter is substantially cylindrical and the capsule is substantially centered relative to the diameter of the cylinder. In some cases, the capsule is essentially centered relative to the length of the cylinder. In some cases, the cylindrical filter may be approximately 8-14 mm in length, respectively 9-13 mm or 10-12 mm. It can have a cross-sectional diameter of approximately 5-9 mm, correspondingly 7.5-8 mm. It can be formed from fibers based on cellulose acetate.

In some cases, the pressure difference across the filter when the user inhales is in the range of 30 to 90 mmH2O when the capsule is in an unsqueezed state. Accordingly, the differential pressure across the filter may range from about 30 mmHgO, 33 mmHgO, 35 mmHgO, 38 mmHgO or 40 mmHgO to about 90 mmHgO, 75 mmHgO, 65 mmHgO, 60 mmHgO, 55 mmHgO or 50 mmHgO when the capsule is in an uncrushed state. By way of illustration, the pressure difference across the filter when the capsule is in an unsqueezed state may be in the range of approximately 35-60 mmNegO, preferably 38-55 mmNegO or 40-50 mmNegO.

In some cases, the filter contains only one capsule. In other cases, the filter contains more than one capsule. When a filter contains multiple capsules, the individual capsules may be the same compared to each other or may differ. For example, multiple capsules may be provided such that the user can choose when/or to crush the capsule, thereby controlling the aerosol delivery profile.

In some cases, the aerosol generating medium contains an aerosol generating agent. In some cases, the aerosol generating medium contains tobacco material. In some 60 cases, the aerosol generating medium contains a flavoring agent. In some cases, the aerosol generating medium consists essentially of or contains an aerosol generating medium and/or tobacco material and/or a flavoring agent. In some cases, the aerosol generating medium may be provided as a single continuous component. In other cases, the medium generating the aerosol may contain distinct sections containing different compositions.

For example, an aerosol-generating medium may contain an aerosol-generating medium and a tobacco material, and they may be provided in distinct separate sections of the aerosol-generating medium.

In some embodiments, the capsule contains a flavoring and the aerosol generating medium contains a flavoring, wherein the flavoring in both cases is essentially the same.

This can ensure the delivery of a richer flavor profile. In some cases, the capsule contains menthol and the aerosol generating medium contains menthol.

In the context of this document, the term "tobacco material" refers to any material containing tobacco or its derivatives. The term "tobacco material" may include one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes. Tobacco material may include one or more of ground tobacco, tobacco fiber, cut tobacco, pressed tobacco, tobacco stalk, reconstituted tobacco tobacco and/or tobacco extract.

The tobacco used to produce the tobacco material may be any suitable tobacco, such as single varieties or blends, cut tobacco or whole leaf tobacco, including Migdipia, and/or Vigieu, and/or Ogiepia). It may also be tobacco fines or dust, expanded tobacco, stalks, expanded stalks, and other processed stalk materials such as cut and twisted stalks. The tobacco material may be crushed tobacco or reconstituted tobacco material. The regenerated tobacco material may contain tobacco fibers and may be formed by casting, a Fourdrinier papermaking method with the reverse addition of tobacco extract, or by extrusion.

In the context of this document, the term "aerosol generating agent" refers to an agent that facilitates the generation of an aerosol. The aerosol generating agent may facilitate the generation of the aerosol by facilitating the initial vaporization and/or condensation of the gas to form a solid and/or liquid inhalable aerosol.

Suitable aerosol generating agents include, but are not limited to, polyols such as sorbitol, glycerin, and glycols such as propylene glycol or triethylene glycol; substances that are not polyols 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 carboxylic acid esters such as methyl stearate, dimethyl dodecanedioate and dimethyl tetradecanedioate. In some cases, the aerosol generating agent may contain glycerin and/or propylene glycol.

In some cases, the aerosol-generating medium contains at least 10 95 by weight of the aerosol-generating medium, based on the total weight of the aerosol-generating medium. Accordingly, the aerosol-generating medium contains at least 12 95, 15 95, 18 95, or 20 95 by weight of the aerosol-generating medium, based on the total weight of the aerosol-generating medium. The residue may, in some cases, be tobacco material.

In some cases, the product that heats but does not burn may be essentially cylindrical.

In some cases, a product that heats, but does not burn, may additionally contain a cooling element. It can be located between the filter and the aerosol generating medium, for example. A cooling element, if present, places the filter at a distance from the hottest parts (during use) of the product, which heats, but does not burn. The cooling element, if present, may contain an unfilled tube suitably formed from paper. The vaporized components of the aerosol generating medium may condense to form an aerosol when used in a cooling element, if present.

A product that heats, but does not burn, may additionally contain ventilation holes. They can be located in the side wall of the product. In some cases, vents may be located in the filter and/or cooling element. During use, these holes allow cold air to be drawn into the product, which mixes with the heated vaporized components, thus cooling the aerosol.

Ventilation improves the generation of visible heated vapors from the product as it heats up during use. The heated vaporized components become visible as a result of the cooling process of the heated vaporized components, resulting in supersaturation of the heated vaporized components. The heated vaporized components then undergo a process of droplet formation, also known as condensation nucleation, and, as a result, the aerosol particle size of the heated vaporized components increases due to further condensation of the heated vaporized components and coalescence of newly formed droplets from the heated vaporized components.

In some cases, the ratio of cold air to the sum of heated vaporized components and cold air, known as the ventilation ratio, is at least 15 95.

A ventilation ratio of 1595 makes the heated vaporized components visible using the method described above. Visibility of the heated vapor components allows the user to determine that the vapor components have been generated and adds to the flavor sensation during smoking.

In another example, the ventilation ratio is from 50 95 to 85 95 to provide additional cooling of heated vaporized components.

In the context of this document, the term "heat-but-not-burn assembly" refers to a combination of a heat-but-not-burn product and a heater. The heater heats the aerosol generating medium of the heating but non-combusting product without burning to vaporize the substrate components and generate an inhalable vapor or aerosol.

In some cases, the heater may be provided as a single unit with the product. For example, the heater may be a combustible fuel source that is attached to the product so that when used, the combustion of the fuel source heats the aerosol generating medium without burning that medium. In another example, the heater may contain a chemical heat source, such as a phase transition material, that undergoes an exothermic reaction to generate heat during use.

In other cases, the heater may be a separate object designed for use with the product. For example, a heater can be a device in which a product that heats, but does not burn, is at least partially inserted. In another example, the heater may be a device that is at least partially embedded in the product that heats but does not burn. The heater can be electrically controlled. In some cases, the heater includes a thin film, electric

A resistive heater, inductive heater or similar.

In some cases, the assembly may be configured such that at least a portion of the aerosol generating medium in the heating but not burning product is exposed to a temperature of at least 1802 or 20022 for at least a 50 95 heating period. In some examples, the aerosol generating medium may be subjected to a thermal profile as described in related application PCT/EP2017/068804, the contents of which are fully incorporated herein.

In some specific cases, a unit that heats, but does not burn, is provided, which is made with the possibility of separate heating of two parts of the medium that generates the aerosol.

By adjusting the temperature of the first and second parts over time so that the temperature profiles of the parts are different, it is possible to adjust the aerosol puff profile during use. The heat provided to the two parts of the aerosol-generating medium may be provided at different times or with different intensities; step heating in this way can provide both rapid aerosol formation and long duration of use.

In one specific example, the assembly can be designed in such a way that when the consumption session is initiated, the first heating element corresponding to the first part of the aerosol generating medium is immediately heated to a temperature of 240 "C. This first heating element is maintained at a temperature of 240 "C for 145 seconds and then drops to 135 "C (where it remains for the rest of the consumption session). 75 seconds after the initiation of the consumption session, the second heating element corresponding to the second part of the aerosol generating medium is heated to a temperature of 160 "C. 135 seconds after the initiation of the consumption session, the temperature of the second heating element rises to 240 "C (where it remains for the rest of the consumption session). The consumption session lasts 280 seconds, and at the end of the session, both heaters have already cooled to room temperature.

In some cases, the unit is designed in such a way that the filter of the product that heats, but does not burn, is not directly heated. For example, in cases where the heater is a device in which the product is partially inserted, the unit can be designed in such a way that the filter of the product that heats, but does not burn, is not inserted into the device. 60 In some specific cases, the node is designed in such a way that the filter, if present,

the cooling element of the product, which heats but does not burn, is not directly heated. For example, in cases where the heater is a device in which the product is partially inserted, the unit can be made in such a way that the filter and, if available, the cooling element of the product that heats, but does not burn, are not inserted into the device. In other cases, at least part of the cooling element may be inserted into the device.

In such cases, even when the filter is not directly heated, heat will be drawn in through the heating but not burning product during the consumption session (when the user takes a puff). The authors of this invention found that the temperature profile of the center of the filter reaches a maximum during each puff. This is due to the hot aerosol that is drawn in through the filter during puffing. In some cases, the filter (and its capsule) may be exposed to temperatures greater than about 302C, 402C, or 502C during use. In some cases, the maximum temperature to which the filter (and capsule) is exposed during use is less than about 1002, 909C, 809, or 702C. In some cases, the filter (and capsule) may be exposed to temperatures in the range of 3309C to 10092C, 409C to 802C or 509 to 7096C, respectively.

The authors of this invention have found that the capsules defined in point 1 are particularly suitable for use in a product that heats, but does not burn. Even though the capsules may, in some cases, be exposed to temperatures in excess of the shell's melting point or glass transition temperature, it has been found that the capsules defined in 1 are less likely to break or crack under conditions in a heating but not burning assembly , compared to other capsules. Such capsules can be easily crushed by the user before, during or after the initiation of heating to release their content elements. A crackling sensation is maintained during crushing, providing the user with tactile feedback that crushing has occurred. This snapping sensation is useful as the user then knows that a sufficient level of pressure has been applied and that the capsule contents have been released.

In this way, excessive pressure is less likely to be applied, which can damage the heating but not burning product.

Without being limited by theory, the suitability of the capsules described herein for

From use in a product that heats, but does not burn, it is considered a consequence of the composition of the material of the shell and the absorption of water. Other factors that may be relevant include the heat capacity of the shell material, the melting point or glass transition temperature of the shell material, and/or the distance of the capsule from the heater.

In some cases, the capsule may be placed within the heating but not burning article such that it is at least about 25 mm or at least about 30 mm from the heater in the heating but not burning assembly. In some cases, the capsule can be placed inside the product that heats, but does not burn, so that it will be at a distance of 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 nearest point of the heater.)

This position determination may mean that the capsule is exposed to the appropriate level of heat while ensuring that the heating but not burning product is of the appropriate size.

Capsules formed from a shell material containing carrageenan with a melting point of at least 30°C or at least 40°C have been found to withstand heat rather than combustion conditions very well.

An example of a product that heats, but does not burn, is illustrated in Fig. 1. The illustrated product 10, which heats but does not burn, is essentially cylindrical in shape. It may contain a rod of medium 1 that generates an aerosol, accordingly, a rod of tobacco material is located on the side of the first end 2, and the filter C on the side of the second end 4. The second end 4 is a mouthpiece end. The capsule 5 is placed inside the filter 3. The filter C contains a filter material, which can be cellulose acetate. The paper cover 6 holds the components in a cylindrical configuration and provides a channel 7 between the tobacco rod 1 and the rod C of the filter. Channel 7 functions as a cooling element and may be omitted in alternative embodiments. An additional short channel is shown between the rod C of the filter and the second end 4. It may also be omitted in alternative embodiments.

In use, the heat-but-not-burn product 10 is partially inserted into the heater of the heat-but-not-burn assembly (not shown) so that it can be heated to form an inhalable aerosol. In an embodiment, the heater forms an oven-like arrangement around the aerosol generating medium. In some embodiments, the first end 2 of the product 10, which heats but does not burn, is inserted in such a way that the aerosol-generating medium 1 is contained within the heater. Product 10, which heats, but does not burn, and the assembly, which heats, but does not burn, are made in such a way that the filter C and at least some part of the channel 7 are not in the heater.

In alternative embodiments, the essentially cylindrical product that heats but does not burn may contain an aerosol-generating medium 1 directly adjacent to the filter 3. The channel may be provided on the opposite side of the filter relative to the medium, or the passage may be absent.

After use, the product that heats, but does not burn, is removed from the heater and, as a rule, thrown away. During further uses of the heater, additional products are used that heat, but do not burn.

An alternative assembly that heats, but does not burn, is shown in fig. 2. In this unit, the combustible heat source 8 is located adjacent to the aerosol-generating medium 1 at the first end 2 of the product 10, which heats but does not burn. The combustible heat source 8 may be separated from the aerosol-generating medium 1 by means of a non-combustible material (not shown), such as a layer of aluminum foil. Aluminum foil or other conductive non-combustible materials are useful because they (a) conduct heat to the aerosol-generating medium and (b) prevent the fuel source from burning, which results in combustion of the aerosol-generating medium. During use, the fuel source 8 is ignited by the user; heat is conducted via aluminum foil (etc.) to the aerosol-generating medium 1, vaporizing the components of medium 1 without combustion.

In fig. 4 show a partial cross-sectional view and a perspective view of an example of a heating but non-burning product 101 similar to that shown in FIG. 1. Product 101 is adapted for use with a device that has a power source and a heater. The product 101 according to this embodiment is particularly suitable for use with the device 51 shown in FIG. 7-9 and described below. During use, the product 101 can be removably inserted into the device shown in FIG. 7, in the place 20 of the insertion of the device 51.

The product 101 according to one example is essentially in the shape of a cylindrical rod, which contains the main part of the medium 103, which generates an aerosol, and the node 105 of the filter in the form of a rod.

The filter assembly 105 contains three segments: cooling segment 107, filtering

From segment 109 and segment 111 of the mouthpiece end. The article 101 has a first end 113, also known as the mouthpiece end, or near end, and a second end 115, also known as the far end. The main portion of the aerosol generating medium 103 is located toward the distal end 115 of the article 101. In one example, the cooling segment 107 is located adjacent to the main portion of the aerosol generating medium 103 between the main portion of the aerosol generating medium 103 and the filter segment 109 , so that the cooling segment 107 is adjacent to the aerosol generating medium 103 and the filtering segment 103. In other examples, a gap may be provided between the main part of the aerosol generating medium 103 and the cooling segment 107 and between the main part of the generating medium 103 aerosol, and the filtering segment 109. The filtering segment 109 is located between the cooling segment 107 and the segment 111 of the mouthpiece end. The mouthpiece end segment 111 is located near the proximal end 113 of the product 101, adjacent to the filter segment 109. In one example, the filter segment 109 is adjacent to the mouthpiece 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 embodiment, the bulk of the aerosol generating medium 103 contains tobacco. However, in other suitable embodiments, the bulk of the aerosol generating medium 103 may consist of tobacco, may consist essentially entirely of tobacco, may contain tobacco and other components such as an aerosol generating agent and/or a flavoring agent. In some cases, the aerosol generating medium may not contain tobacco.

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

In one example, the overall length of the product 101 is between 71 mm and 95 mm, respectively between 79 mm and 87 mm, respectively 83 mm.

The axial end of the main portion of the aerosol generating medium 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 include an end member (not shown) that covers the axial end of the main portion of the generating medium 103 aerosol. because the body of the aerosol generating medium 103 is attached to the filter assembly 105 by means of an annular rim paper (not shown) which is located substantially around the periphery of the filter assembly 105 to surround the filter assembly 105 and extends partially along the length of the body of the medium 103, which generates an aerosol. In one example, the rim paper is made from a standard 58 gsm base paper. In one example, the rim paper has a length of 42 mm to 50 mm, correspondingly 46 mm.

In one example, the cooling segment 107 is an annular tube and is located circumferentially and defines an air gap in the cooling segment. The air gap provides a chamber for the flow of heated vaporized components generated from the bulk of the aerosol generating medium 103 . The cooling segment 107 is hollow to provide an aerosol collection chamber, but rigid enough to resist axial compressive forces and bending moments that may occur during manufacture and use of the article 101 during insertion into the device 51. In one example, the wall thickness of the cooling segment 107 is approximately 0.29 mm.

The cooling segment 107 provides a physical distance between the aerosol generating medium 103 and the filter segment 109. The physical distance provided by the cooling segment 107 will provide a temperature drop along the length of the cooling segment 107. In one example, the cooling segment 107 is designed to provide a temperature drop of at least 40 degrees Celsius between the heated vaporized component entering the first end of the cooling segment 107 and the heated vaporized component exiting the second end of the cooling segment 107 .

In one example, the cooling segment 107 is designed to provide a temperature difference of at least 60 degrees Celsius between the heated vaporized component entering the first end of the cooling segment 107 and the heated vaporized component exiting the second end of the cooling segment 107. This temperature difference along the length of the cooling of the element 107 provides protection of 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 a physical distance was not provided between the filter segment 109 and the main part of the aerosol-generating medium 103 and the heating elements of the device 51, the temperature-sensitive filter segment 109 may become damaged during use, causing it to not perform its required functions as 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, respectively 25

MM.

The cooling segment 107 is made of paper, meaning that it contains a material that does not generate hazardous compounds, such as toxic compounds, when in use adjacent to the heater of the device 51. In one example, the cooling segment 107 is made of a spirally twisted paper tube , which provides a hollow inner chamber, but at the same time maintains mechanical rigidity. Spiral wound paper tubes can meet the strict 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 obtained by forming an indentation in a rigid fizel or rim paper. The rigid fizel or rim paper is manufactured to have sufficient stiffness to resist axial compressive forces and bending moments that may occur during manufacture and application of the article 101 during insertion into the device 51.

The filter segment 109 may be formed of any filter material suitable for removing one or more vaporized compounds from the heated vaporized components of the aerosol generating medium. In one example, the filter segment 109 is made of a monoacetate material, such as cellulose acetate. Filter segment 109 provides cooling and reduced irritation from heated vaporized components without consuming the amount of heated vaporized components to a level unsatisfactory to the user.

A fragile capsule 5 is provided in the filter segment 109. It can be placed essentially centrally in the filter segment 109, both in the diameter of the filter segment 109 and in the length of the filter segment 109. In other cases, it can be offset by one or more amounts.

The density of the cellulose acetate tow material of the filter segment 109 determines the pressure drop across the filter segment 109, which in turn determines the pull-in resistance of the product 101. Thus, the selection of the material of the filter segment 109 is important when adjusting the pull-in resistance of the product 101. In addition , the filtering segment performs the filtering function in the product 101.

In one example, the filter segment 109 is made of 8U15 grade filter mat material, which provides a filtering effect for the heated vaporized material, while also reducing the size of the condensed aerosol droplets that form as a result of the heated vaporized material.

The presence of the filter segment 109 provides an insulating effect by providing additional cooling of the heated vaporized components that exit 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, the filter segment 109 is between 6 mm and 10 mm in length, correspondingly 8 mm.

The segment 111 of the mouthpiece end is an annular tube and is located in a circle and defines the air gap in the segment 111 of the mouthpiece end. The air gap provides a chamber for the heated vaporized components that flow from the filter segment 109.

The mouthpiece end segment 111 is hollow to provide an aerosol collection chamber, but rigid enough to resist axial compressive forces and bending moments that may occur during manufacture and application of the article during insertion into device 51. In one example, the wall thickness of segment 111 of the mouthpiece end is approximately 0.29 mm. In one example, the length of the mouthpiece end segment 111 is between b mm and 10 mm, correspondingly 8 mm.

The mouthpiece end segment 111 can be made from a spirally twisted paper tube, which provides a hollow inner chamber, yet maintains critical mechanical stiffness. Spiral wound paper tubes can meet the strict dimensional accuracy requirements of high-speed manufacturing processes with respect to tube length, outer diameter, roundness and straightness.

The nozzle end segment 111 provides the function of preventing any liquid condensate accumulated at the outlet of the filter segment 109 from entering the immediate

From contact with the user.

It should be understood that in one example, the mouthpiece end segment 111 and the cooling segment 107 may be formed from the same tube, and the filter segment 109 is located inside this tube, separating the mouthpiece end segment 111 from the cooling segment 107.

In fig. 5 and 6 show partial cross-sectional and perspective views of an example product 301.

Reference positions shown in fig. 5 and 6, equivalent to the reference positions shown in fig. Z and 4, but increased by 200.

In the example of the product 301, which is shown in fig. 5 and 6, a vent section 317 is provided in the article 301 to allow air to flow into the interior of the article 301 from the outside of the article 301. In one example, the vent section 317 is in the form of one or more vent slots 317 that pass through the outer layer of the article 301. The vent slots may be located in the cooling segment 307 to facilitate cooling of the product 301. In one example, the ventilation section 317 includes one or more rows of slots, and preferably each row of slots is located circumferentially around the product 301 in a cross section that is substantially perpendicular to the longitudinal axis of the product 301 .

In one example, one to four rows of vents are provided to provide ventilation to the product 301. Each row of vents may have 12 to 36 vents 317. The vents 317 may, for example, have a diameter of 100 to 500 µm. In one example, the distance along the axis between the rows of ventilation slots 317 is from 0.25 mm to 0.75 mm, preferably 0.5 mm.

In one example, the vents 317 are the same size. In another example, the vents 317 have different sizes. The ventilation slots can be made using any suitable technique, for example, one or more of the following techniques: laser technology, mechanical perforation of the cooling segment 307, or pre-perforation of the cooling segment 307 before it is formed on the product 301.

The ventilation slots 317 are arranged to provide effective cooling of the product 301.

In one example, the rows of vents 317 are spaced at least 11 mm from the proximal end 313 of the product, preferably 17 mm to 20 mm from the proximal end 313 of the product 301. The vents 317 are spaced so that the user does not block the vents 317 when using product 301.

By providing rows of vents 17 mm to 20 mm from the proximal end 313 of the product 301, the vents 317 can be located outside of the device 51 when the product 301 is fully inserted into the device 51, as can be seen in FIG. 8 and 9. Due to the location of the ventilation slots outside the device, unheated air can enter the product 301 through the ventilation slots from the outside of the device 51, helping to cool the product 301.

The length of the cooling segment 307 is such that the cooling segment 307 will be partially inserted into the device 51 when the product 301 is fully inserted into the device 51. The length of the cooling segment 307 performs the first function of providing a physical gap between the heating structure of the device 51 and the heat-sensitive filter structure 309 , and the second function: provides the possibility of locating the ventilation slots 317 in the cooling segment, which are also located outside the device 51 when the product 301 is fully inserted into the device 51. As can be seen in fig. 8 and 9, most of the cooling element 307 is located within the device 51. However, there is a portion of the cooling element 307 that extends beyond the device 51. It is in this portion of the cooling element 307 that extends beyond the device 51 that the ventilation slots 317 are located.

In fig. 7-9 shows in more detail an example of the device 1, made with the possibility of heating the aerosol-generating medium, for vaporizing at least one component of the specified aerosol-generating medium, as a rule, with the formation of an aerosol that can be inhaled. Device 51 is a heating device that releases compounds by heating, but not burning, the medium that generates the aerosol.

The first end 53 is sometimes referred to herein as the mouthpiece end or near end 53 of the device 51, and the second end 55 is sometimes referred to herein as the far end 55 of the device 51. The device 51 has an on/off button 57 to allow the entire device 51 to be turned on and off by at the user's request.

The device 51 includes a housing 59 for housing and protecting the various internal components of the device 51. In the example shown, the housing 59 provides a monolithic housing 11 that surrounds

A perimeter of the device 51 is covered by a top panel 17, which generally defines the "top" of the device 51, and a bottom panel 19, which generally defines the "bottom" of the device 51. In another example, the housing includes a front panel, a back panel, and a pair of opposite side panels in addition to the top panel 17 and bottom panel 19.

The upper panel 17 and/or the lower panel 19 may be detachably attached to the monolithic housing 11 to provide easy access to the interior of the device 51, or may be attached to the monolithic housing 11 "without the possibility of detachment", e.g. in order to limit the user's access to the interior of the device 51. In one example, the panels 17 and 19 are made of a plastic material, including, for example, injection-molded Skleneylon, and the monolithic housing 11 is made of aluminum, although other materials may be used materials and other production processes.

The upper panel 17 of the device 51 has an opening 20 at the mouthpiece end 53 of the device 51 through which, during use, the product 101, 301 containing an aerosol generating medium can be inserted into the device 51 and removed from the device 51 by the user.

The housing 59 houses or attaches: heating structure 23, control circuit 25 and power source 27. In this example, the heating structure 23, the control circuit 25, and the power source 27 are adjacent in the lateral direction (ie, adjacent when viewed from the end), and the control circuit 25 is usually placed between the heating structure 23 and the power source 27, although other placement options are possible .

The control circuit 25 may include a controller, such as a microprocessor device, configured and configured to control the heating of the aerosol generating medium in the product 101, 301, as will be further described below.

The power supply unit 27 can be, for example, 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. A battery 27 is electrically connected to a heating structure 23 to supply electricity on demand and is controlled by a control circuit 25 to heat the aerosol generating medium in the article (as described to vaporize the aerosol generating medium without causing the medium to burn, which generates an aerosol). because the advantage of placing the power source 27 laterally adjacent to the heating structure 23 is that a large power source 25 can be used without the need for excessive elongation of the entire device 51. As will be understood, usually a large power source 25 has a larger capacity (ie, the total electrical energy that can be supplied, often measured in ampere-hours or similar units), and thus the battery life for the device 51 can be longer.

In one example, the heating structure 23 is generally in the form of a hollow cylindrical tube having a heating chamber 29 with a hollow interior into which an article 101, 301 containing an aerosol generating medium is inserted for heating during use. Various layouts of the heating structure 23 are possible.

For example, the heating structure 23 may contain one heating element or may be formed from several heating elements installed in a row along the longitudinal axis of the heating structure 23. Said or each heating element may be annular or tubular, or at least partially annular or partially tubular along its circumference .

In one example, the or each heating element may be a thin film heater. In another example, the or each heating element may be made of a ceramic material. Examples of suitable ceramic materials include aluminum oxide and aluminum nitride, and silicon nitride ceramics, which can be layered and sintered. Other heating designs are possible, including, for example, an inductive heating device, infrared heating elements that heat by emitting infrared radiation, or resistive heating elements formed by, for example, a resistive electrical winding.

In one particular example, the heating structure 23 rests on a stainless steel support tube and contains a polyimide heating element. The heating structure 23 is sized such that substantially the entire bulk of the aerosol generating medium 103 , 303 of the product 101 , 301 is inserted into the heating structure 23 when the product 101 , 301 is inserted into the device 51 .

Said or each heating element may be positioned such that selected zones of the aerosol generating medium may be heated independently, for example alternately (over time as described above) or together (simultaneously), as desired.

The heating structure 23 in this example is surrounded along at least part of its length by a thermal insulator 31. The insulator 31 helps to reduce heat transfer from the heating structure 23 to the exterior of the device 51. This helps to reduce the energy requirements for the heating structure 23 because it reduces heat loss in general.

The insulator 31 also helps to keep the exterior of the device 51 cool during operation of the heating structure 23. In one example, the insulator 31 may be a double-walled jacket that provides a low pressure zone between the two walls of the jacket. That is, the insulator 31 can be, for example, a "vacuum" tube, that is, a tube that is at least partially vacuumed to minimize heat transfer by thermal conduction and/or convection. Other options for performing the insulator 31 are possible, including the use of thermal insulation materials, including, for example, a suitable foam material, in addition to or instead of a jacket with two walls.

The housing 59 may additionally contain various internal support structures 37 to support all internal components as well as the heating structure 23.

The device 51 also includes a ring 33 that surrounds the opening 20 and protrudes from it into the interior of the housing 59 and a generally tubular chamber 35 located between the ring 33 and one end of the vacuum jacket 31. The chamber 35 additionally contains a cooling structure C51, which, in this example, includes a plurality of cooling fins 35i spaced from each other along the outer surface of the chamber 35, each of which is located in a circle around the outer surface of the chamber 35. Between the hollow chamber 35 and the product 101, 301 when it is inserted into the device 51, an air gap 36 is provided over at least part of the length of the hollow chamber 35. The air gap 36 passes around the entire circumference of the product 101, 301 over at least part of the cooling segment 307.

The ring 33 includes a plurality of protrusions 60 that are arranged in a circle around the periphery of the opening 20 and that protrude into the opening 20. The protrusions 60 occupy the space inside the opening 20 in such a way that the open area of the opening 20 in the places where the protrusions 60 are located is smaller than the open area of the opening 20 in places without protrusions 60. The protrusions 60 are designed to engage with the product 101, 301 inserted into the device to facilitate its fixation within the device 51. The open spaces (not shown in the figures) defined by adjacent pairs of protrusions 60 and the product 101, 301, form ventilation channels around the exterior of the product 101, 301. These ventilation channels 60 allow hot steam released from the product 101, 301 to exit the device 51, and allow cooling air to flow into the device 51 around the product 101, 301 into the air gap 36.

When using the product 101, 301 is inserted with the possibility of disconnection in the place 20 of the device 51 insertion, as shown in fig. 7-9. As specifically shown in fig. 8, in one example, the main portion of the aerosol generating medium 103, 303, which is located near the distal end 115, 315 of the article 101, 301, is entirely contained within the heating structure 23 of the device 51. The proximal end 113, 313 of the article 101, 301 projects from the device 51 and functions as a mouthpiece assembly for the user.

In use, the heating structure 23 will heat the product 101 , 301 to vaporize at least one component of the aerosol generating medium from the main portion of the aerosol generating medium 103 , 303 .

The main flow channel for the heated vaporized components from the main part of the aerosol generating medium 103, 303 passes axially through the product 101, 301, through the chamber in the cooling segment 107, 307, through the filter segment 109, 309, through the segment 111, 313 mouthpiece end to the user. In one example, the temperature of the heated vaporized components generated from the bulk of the aerosol generating medium is between 60°C and 250°C, which may be above the acceptable inhalation temperature for the user. As the heated vaporized component passes through the cooling segment 107, 307, it cools, and some of the vaporized components condense on the inner surface of the cooling segment 107, 307.

In the examples of the product 301 shown in fig. 5 and b, cold air may enter the cooling segment 307 through vents 317 formed in the cooling segment 307. The cold air mixes with the heated vaporized components to provide additional cooling of the heated vaporized components.

The ventilation improves the generation of visible heated vaporized components from the product 317 as it is heated in use by the device 51. The heated vaporized components become visible as a result of the cooling process of the heated vaporized components, resulting in supersaturation of the heated vaporized components. The heated vaporized components then undergo a process of droplet formation, also known as condensation nucleation, and, in

As a result, the aerosol particle size of the heated vaporized components increases due to further condensation of the heated vaporized components and coalescence of newly formed droplets from the heated vaporized components.

In one embodiment, the ratio of cold air to the sum of the heated vaporized components and cold air, known as the ventilation ratio, is at least 15 95. A ventilation ratio of 15 95 allows the heated vaporized components to become visible using the method described above. Visibility of the heated vapor components allows the user to determine that the vapor components have been generated and adds to the flavor sensation during smoking.

In another example, the ventilation ratio is from 50 95 to 85 95 to provide additional cooling of heated vaporized components.
