A first aspect of the invention provides a non-combustion heated article comprising an aerosol-generating medium and a filter, the filter containing one or more collapsible capsules, and in use, the aerosol-generating medium is heated without being combusted, the capsule is exposed to temperatures of approximately 30-100°C; during such exposure, the structural integrity of the capsule is not compromised, so that the user The capsules can be crushed before, during or after heating.

Aerosols produced by non-combustion heated products are typically warm and moist due to the characteristics of the heating profile and the composition of the aerosol generating medium. For example, the aerosol-generating medium of a non-combustible heated product according to the invention may include a greater proportion of aerosol-generating agent than the smokable material used in the combustible product. Additionally or alternatively, the aerosol-generating medium of a non-combustible heated product according to the invention can be heated to a higher temperature and/or for a longer time than the combustion temperature/time of the combustible product. The inventors have found that the capsule detailed in claim 1 is particularly suitable for use in and in non-combustible heated products. The capsule defined in claim 1 has been found to be less prone to failure and rupture when exposed to conditions within a non-combustion heated product compared to other capsules.

In some cases, during use, the aerosol-generating medium produces a high humidity aerosol and the capsule is exposed to at least 12 mg of water.

The inventors have determined that the temperature profile in the center of the filter peaks with each puff during use. This is due to the hot aerosol being drawn through the filter during puffing. In some cases, the capsules may be exposed to temperatures in excess of about 30°C, 40°C, or 50°C during use. In some cases, the maximum temperature to which the capsule is exposed during use is less than about 100°C, 90°C, 80°C, or 70°C. In some cases, the capsules may be exposed to temperatures in the range of 30°C to 100°C, suitably 40°C to 80°C or 50°C to 70°C.

As used herein, the term "non-combustible heated article" refers to an article that includes an aerosol-generating medium, where, in use, the components of the aerosol-generating medium are volatilized by heating without combustion to form an inhalable vapor or aerosol.

The aerosol-generating medium of a non-combustion heated article includes a solid component (in contrast to the aerosol-generating medium of an e-cigarette, where the aerosol-generating medium is a liquid). By "solid" it is meant that the aerosol-generating medium exhibits no flowability during steady state conditions. Solids may include gels and the like. For the avoidance of doubt, the aerosol generating medium of a non-combustion heated article may include a liquid component in addition to a solid component.

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

A capsule shell material (sometimes alternatively referred to herein as a barrier material or an encapsulating material) surrounds the core. The shell material may in some cases have the ability to minimize core movement during storage of the product. In some cases, the shell material can control the release of the core during use. The capsule can be ruptured (ie, crushed) to release the contents before, during, or after heating the non-combustible heated article.

The capsule shell material is crushable, ie, brittle or brittle. The capsule may be crushed or broken or broken by the user to release the contents. Typically, the capsule is broken just before heating begins, but the user can choose when to release the contents (ie, can be crushed after heating begins). The term "crushable capsule" refers to a capsule whose encasing material (which may be a shell) can be broken by pressure to release the encased material (which may be a capsule core); More specifically, the encasing material (e.g. shell) is capable of absorbing pressure under the pressure applied by the user's fingers (or any other pressure generating means) when the user wishes to release the contents of the capsule. , can be divided. In some cases, the capsules can have an initial (before heating) breaking strength of about 0.8 kp to about 3.5 kp, which can be about 1.0 kp to about 2.5 kp or about 1.0 to about 2 .0 kp is appropriate. The inventors have determined that heating can weaken the capsule. The inventors have determined that capsules with an initial breaking strength of at least 0.8 kp are resistant to breaking/cracking when heated. The inventors have confirmed that capsules with a breaking strength greater than 3.5 kp are less likely to break before heating. The inventors have determined that an initial failure strength in the range of 1.0 kp to 2.0 kp provides the best capsule performance.

Illustratively, the diameter of the capsule is about 0.4 mm to about 10.0 mm, about 0.8 mm to about 6.0 mm, about 2.5 mm to about 5.5 mm, or about 2.8 mm to about 3.2 mm. can be in the range of In some cases, the capsule may have a diameter of about 3.0 mm to about 3.5 mm. These dimensions are particularly suitable for incorporating the capsules into filters for non-combustion heated articles.

In some cases, the total weight of the capsules described herein can range from about 1 mg to about 100 mg, 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 is suitable.

In some cases, the total weight of the core formulation can range from about 2 mg to about 90 mg, 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 Approximately 15 mg is suitable.

The shell comprises from 5 to 90% by weight of the total capsule shell weight of a gelling agent, the gelling agent comprising, consisting essentially of carrageenan, or consisting solely of carrageenan. In some cases, the shell comprises 5-60%, 5-50%, or 10-35% by weight of the gelling agent of the total weight of the capsule shell. In some cases, the capsule shell gelling agent includes carrageenan. In some cases, the carrageenan has a melting point of at least about 30°C or at least about 40°C.

Suitable gels include agar, agarose, carrageenan, furoidan, and furcellaran. Suitable waxes include carnauba wax. In some cases, gelling agents may include carrageenan and/or gellan gum, and the pressure required to break the resulting capsules is particularly suitable, so that these gelling agents It is particularly suitable for inclusion as an agent. In some cases, the capsule shell does not contain gelatin.

The capsule shell may further include one or more of fillers, buffers, colorants, and plasticizers.

In some cases, the capsule shell material may include one or more fillers such as starch, modified starch (such as oxidized starch), and sugar alcohols such as maltitol.

In some cases, the capsule shell material may include a coloring agent that more easily represents the location of the capsule within the tobacco industry product being manufactured. Preferably, the colorant is selected from colorants and pigments.

In some cases, the capsule shell material may further include at least one buffering agent, such as a citrate compound or a phosphate compound.

In some cases, the capsule shell material may further include at least one plasticizer, such as glycerol, sorbitol, maltitol, triacetin, polyethylene glycol, propylene glycol, or another polyalcohol, which has plasticizing properties. , optionally one of the mono-, di-, or tri-acid types, such as citric acid, fumaric acid, and malic acid, among others. In some cases, the amount of plasticizer ranges from 1 to 30% by weight of the total weight of the shell, preferably from 2 to 15%, and more preferably from 3 to 10%. In some cases, the total amount of combined plasticizer and gelling agent in the shell is about 40-70% by weight of the total weight of the capsule shell, suitably 50-60%. In some cases, the plasticizer comprises, consists essentially of, or consists only of glycerol.

In some cases, the capsule shell may also include one or more fillers. Suitable fillers include starch derivatives such as dextrins, maltodextrins, cyclodextrins (alpha, beta, or gamma), or hydroxypropyl-methylcellulose (HPMC), hydroxypropylcellulose (HPC), methylcellulose ( Examples include cellulose derivatives such as methylcellulose (MC) and carboxymethylcellulose (CMC), polyvinyl alcohol, polyols, and mixtures thereof. The capsule shell may in some cases include filler up to about 60% by weight of the total weight of the capsule shell. In some cases, the capsule shell may include filler up to about 50%, 40%, 30%, or 20% by weight of the total weight of the capsule shell. In some specific cases, the capsule shell may be filler-free.

The capsule shell may further include a hydrophobic outer layer that makes the capsule less susceptible to moisture-induced degradation. The hydrophobic outer layer may be a wax, especially carnauba wax, candelilla wax or beeswax, carbowax, shellac (in alcoholic or aqueous solution), ethylcellulose, hydroxypropylmethylcellulose, hydroxypropylcellulose, a latex composition, polyvinyl alcohol, or Suitably selected from the group including combinations thereof. More preferably, the at least one moisture barrier agent is ethylcellulose or a mixture of ethylcellulose and shellac.

The method of making the capsules includes coextrusion, optionally followed by centrifugation and curing and/or drying. These and other suitable techniques are known in the art.

The filter can include filter material. For example, filters may include cellulosic materials such as cellulose acetate, ceramic materials, polylactic acid, polymeric matrices, and/or activated carbon. Suitable examples of ceramic materials include silicon carbide (SiC), silicon nitride (Si ₃ N ₄ ), titanium carbide, and zirconium dioxide (zirconia).

In some cases, the filter material has an average melting point of at least about 150°C. When used in an aerosol generation device, the filter is generally exposed to temperatures below 150° C., and therefore, in such embodiments, the filter does not melt and provides sufficient support for the capsule. This helps the user try to crush the capsule after heating has started. In some cases, the filter material has an average melting point of at least about 160°C, 170°C, 180°C, 190°C, or 200°C.

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 try to crush the capsule after heating has started. 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.

In some cases, the filter may further include a wrapper surrounding other filter components. The wrapper may include tobacco chip paper.

In some cases, the capsule occupies about 5-30% v/v of the filter. In some cases, the capsule contains 70-95% v/v filter material, with acetylcellulose being suitable. The inventors have confirmed that these ratios provide adequate heat absorption 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 substantially centered relative to the length of the cylinder. In some cases, the cylindrical filter may be about 8-14 mm in length, suitably 9-13 mm or 10-12 mm. The filter may have a cross-sectional diameter of about 5-9 mm, suitably 7.5-8 mm. The filter may be formed from acetylcellulose fibers.

In some cases, the pressure difference across the filter when the user inhales is in the range of 30-90 mm H ₂ O with the capsule intact. The pressure difference before and after the filter is approximately 30 mm H ₂ O, 33 mm H ₂ O, 35 mm H ₂ O, 38 mm H 2 O, or 40 mm H ₂ O to approximately 90 mm H ₂ O, 75 mm H ₂ O, 65 mm H ₂ O, when the capsule is _not broken. A range of 60 mm _H2O , 55 mm _H2O , or 50 mm _H2O is suitable. Illustratively, the pressure difference across the filter may be in the range of about 35-60 mm H ₂ O with the capsule unbroken, preferably 38-55 mm H ₂ O or 40-50 mm H ₂ O.

In some cases, the filter contains only one capsule. In other cases, the filter contains more than one capsule. If the filter comprises multiple capsules, the individual capsules may be the same or different from each other. For example, multiple capsules can be provided so that the user can choose when/if to break the capsule, thereby controlling the aerosol delivery profile.

In some cases, the aerosol-generating medium includes an aerosol-generating agent. In some cases, the aerosol-generating medium includes tobacco material. In some cases, the aerosol-generating medium includes a flavoring agent. In some cases, the aerosol-generating medium consists essentially of an aerosol-generating agent and/or a tobacco material and/or a flavoring agent, or consists only of an aerosol-generating agent and/or a tobacco material and/or a flavoring agent. . In some cases, the aerosol generating medium may be provided as a single unitary component. In other cases, the aerosol-generating medium may comprise separate portions containing different components. For example, the aerosol-generating medium includes an aerosol-generating agent and a tobacco material, which may be provided in separate parts of the aerosol-generating medium.

In some cases, the capsule contains a flavoring agent and the aerosol-generating medium includes a flavoring agent, and the flavoring agent is substantially the same in both cases. This can provide a more consistent delivery of fragrance profiles. In some cases, the capsule contains menthol and the aerosol-generating medium includes menthol.

As used herein, the term "tobacco material" refers to any material that contains tobacco or its derivatives. The term "tobacco material" may include one or more of tobacco itself, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes. The tobacco material may include one or more of ground tobacco, tobacco fiber, shredded tobacco, extruded tobacco, tobacco stalks, regenerated tobacco, and/or tobacco extract.

The tobacco used to produce the tobacco material may be any suitable tobacco, such as single grades or blends, chopped rags or whole leaves, including Virginia and/or Burley and/or Oriental. The tobacco may also be "fines" or powder of tobacco particles, expanded tobacco, stems, expanded stems, and other processed stem materials such as cut-rolled stems. The tobacco material may be ground tobacco or recycled tobacco material. The recycled tobacco material may include tobacco fibers and may be formed by casting, Fourdrinier-type means with inverse addition of tobacco extract, or by extrusion.

As used herein, the term "aerosol generating agent" refers to an agent that promotes the production of aerosol. Aerosol generating agents can facilitate aerosol production by promoting the initial evaporation and/or condensation of gases into respirable solid and/or liquid aerosols.

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

In some cases, the aerosol-generating medium includes at least 10% by weight of an aerosol-generating agent based on the total weight of the aerosol-generating medium. Suitably, the aerosol-generating medium comprises at least 12%, 15%, 18%, or 20% by weight of an aerosol-generating agent based on the total weight of the aerosol-generating medium. The remainder can be tobacco material in some cases.

In some cases, the non-combustion heated article may be substantially cylindrical.

In some cases, the non-combustion heated article may further include a cooling element. A cooling element may be placed, for example, between the filter and the aerosol-generating medium. The cooling element, if present, separates the filter from the hottest part of the non-combustion heated article (in use). The cooling element, if present, may comprise an empty tube and is suitably formed from paper. In use, the vaporized components of the aerosol-generating medium condense on the cooling element, if present, to form an aerosol.

The non-combustion heated article may further include ventilation openings. These ventilation openings may be provided in the side walls 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, where it mixes with the heated volatile components and cools the aerosol.

When the article is heated during use, this ventilation promotes the production of heated, volatile visible components from the article. The heated volatile component is visualized by a process of cooling the heated volatile component such that supersaturation of the heated volatile component occurs. The heated volatile components then undergo droplet formation, also known as nucleation, which ultimately results in further condensation of the heated volatile components and newly formed droplets from the heated volatile components. Coagulation of the droplets increases the size of the aerosol particles of heated volatile components.

In some cases, the ratio of cold air to the sum of heated volatile components and cold air, known as the ventilation rate, is at least 15%. If the ventilation rate is 15%, the vaporized components heated by the above method can be visualized. When the heated volatilized components are visualized, the user is aware that the volatilized components have been produced, and this adds to the sensory experience of the smoking experience.

In another example, the ventilation rate is between 50% and 85% to further cool the heated volatile components.

As used herein, the term "non-combustion heated assembly" refers to a combination of a non-combustion heated article and a heater. The heater heats the aerosol-generating medium of the non-combustion heated article without combusting it to volatilize the components of the substrate and produce an inhalable vapor or aerosol.

In some cases, the heater may be provided integrally with the article. For example, the heater may be a combustible fuel source attached to the article such that, in use, its combustion heats the aerosol-generating medium without burning it. In another example, the heater may include a chemical heat source, such as a phase change material that undergoes an exothermic reaction to produce heat when used.

In other cases, the heater may be a separate item configured for use with the article. For example, the heater may be a device into which the non-combustion heated article is at least partially inserted. In another example, the heater may be a device that is at least partially inserted into the non-combustion heated article. The heater may be electrically controlled. In some cases, the heater includes a thin film electrical resistance heater, an induction heater, or the like.

In some cases, the assembly may be configured such that at least a portion of the aerosol generating medium of the non-combustion heated article is exposed to a temperature of at least 180°C or 200°C during at least 50% of the heating period. In some examples, the aerosol-generating medium may be exposed to the thermal profile described in co-pending application PCT/EP2017/068804, which is incorporated herein by reference in its entirety.

In some particular cases, a non-combustion heating assembly is provided that is configured to separately heat two portions of the aerosol generating medium. By controlling the temperature of the first and second parts over time so that the temperature profiles of these parts are different, it is possible to control the puff profile of the aerosol during use. The heat supplied to the two parts of the aerosol generation medium can be supplied at different times or ratios, and this staggered heating allows for both rapid aerosol production and extended use. Become.

In one particular example, the assembly can be configured such that at the beginning of the consumption experience, the first heating element corresponding to the first portion of the aerosol-generating medium is immediately heated to a temperature of 240°C. . This first heating element is held at 240°C for 145 seconds and then reduced to 135°C (which is maintained for the remainder of the consumption experience). At 75 seconds after the start of the consumption experience, a second heating element corresponding to the second portion of the aerosol-generating medium is heated to a temperature of 160°C. At 135 seconds after the start of the consumption experience, the temperature of the second heating element is increased to 240°C (which is maintained for the remainder of the consumption experience). The consumption experience lasts 280 seconds, at which point both heaters are lowered to room temperature.

In some cases, the assembly is configured such that the filter of the non-combustion heated article is not directly heated. For example, if the heater is a device into which the article is partially inserted, the assembly may be configured such that the filter of the non-combustion heated article is not inserted into the device.

In some particular cases, the assembly is configured such that the filter and, if any, the cooling element of the non-combustion heated article are not directly heated. For example, if the heater is a device into which the article is partially inserted, the assembly can be configured such that the filter of the non-combustion heated article and the cooling element, if any, are not inserted into the device. In other cases, at least a portion of the cooling element may be inserted within the device.

In such cases, heat is drawn through the non-combustible heated article during the consumption experience (during the user's puff) even though the filter is not directly heated. The inventors have determined that the temperature profile in the center of the filter peaks with each puff. This is due to the hot aerosol being drawn through the filter during puffing. In some cases, the filter (and capsule) may be exposed to temperatures in excess of about 30°C, 40°C, or 50°C during use. In some cases, the maximum temperature to which the filter (and capsule) is exposed during use is less than about 100°C, 90°C, 80°C, or 70°C. In some cases, the filter (and capsule) may be exposed to temperatures in the range of 30°C to 100°C, suitably 40°C to 80°C or 50°C to 70°C.

The inventors have found that the capsule defined in claim 1 is particularly suitable for use in non-combustion heated articles. In some cases, even if the capsule is exposed to temperatures above the melting point or glass transition temperature of the shell, the capsule as defined in claim 1 will be less susceptible to conditions in a non-combustion heated assembly than other capsules. It was found that failure and rupture are less likely to occur when exposed to Such capsules can be easily crushed by the user to release their contents before, during, or after heating begins. The click feeling when squeezing is maintained, which gives the user haptic feedback that it has been squished. This click is then useful because the user knows that sufficient pressure has been applied to release the contents of the capsule. Therefore, the possibility of applying excessive pressure that could damage the non-combustion heated article is reduced.

Without wishing to be bound by theory, it is believed that the suitability of the capsules described herein for use in non-combustion heated articles is due to the composition and water absorption properties of the shell material. 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 positioned within the non-combustion heated article such that it is at least about 25 mm or at least about 30 mm from the heater within the non-combustion heated assembly. In some cases, the capsule may be placed within the non-combustion heated article such that it is about 25-30 mm or about 30-35 mm from the heater (these distances are from the center of the capsule to the nearest point of the heater). ). This positioning may mean ensuring that the non-combustion heated article has the appropriate dimensions while the capsule is exposed to the appropriate heat level.

Capsules formed from shell materials comprising carrageenan having a melting point of at least 30°C or at least 40°C have been found to withstand exposure to non-combustion heated conditions well.

An example of a non-combustion heated article is shown in FIG. The illustrated non-combustion heated article 10 is substantially cylindrical. The article 10 may comprise, towards a first end 2 , a rod of aerosol-generating medium 1 , suitably a rod of tobacco material, and towards a second end 4 a filter 3 . The second end 4 is the end on the mouth side (hereinafter referred to as the "mouth side end"). A capsule 5 is placed within the filter 3. Filter 3 includes a filter material, which may be acetylcellulose. Covering paper 6 holds the components in a cylindrical shape and provides a passageway 7 between tobacco rod 1 and filter plug 3. Passage 7 serves as a cooling element and may be omitted in alternative embodiments. A further short passage is shown between the filter plug 3 and the second end 4. This may also be omitted in alternative embodiments.

In use, the non-combustion heated article 10 is partially inserted into a heater of a non-combustion heated assembly (not shown) so that it can be heated to form an inhalable aerosol. In one embodiment, the heater forms an oven-type arrangement around the aerosol-generating medium. In some embodiments, the first end 2 of the non-combustion heated article 10 is inserted such that the aerosol generating medium 1 enters the heater. The non-combustion heated article 10 and the non-combustion heated assembly are configured such that at least a portion of the filter 3 and passageway 7 do not enter the heater.

In an alternative embodiment, a substantially cylindrical non-combustion heated article may include an aerosol-generating medium 1 immediately adjacent to a filter 3 . The passageway may be provided on the side of the filter opposite the media, or there may be no passageway.

After use, the non-combustion heated article is removed from the heater and typically disposed of. If a heater is subsequently used, an additional non-combustion heated article is used.

An alternative non-combustion heated assembly is depicted in FIG. In this assembly, a combustible heat source 8 is positioned adjacent to an aerosol-generating medium 1 at a first end 2 of a non-combustible heated article 10 . The combustible heat source 8 may be separated from the aerosol-generating medium 1 by a non-combustible material (not shown), such as a layer of aluminum foil. Aluminum foil or other conductive, non-flammable material is useful because it (a) transfers heat to the aerosol-generating medium, and (b) prevents combustion of the fuel source from causing combustion of the aerosol-generating medium. In use, the fuel source 8 is ignited by the user and heat is transferred to the aerosol-generating medium 1 by means of aluminum foil (or the like) to volatilize the components of the medium 1 without combustion.

Referring to FIGS. 3 and 4, shown are partially cut away cross-sectional and perspective views of an example non-combustion heated article 101 similar to that shown in FIG. Article 101 is configured 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 FIGS. 7-9, discussed below. In use, the article 101 can be removably inserted into the device at the insertion point 20 of the device 51 shown in FIG.

One example article 101 is in the form of a substantially cylindrical rod that includes a body of aerosol generating medium 103 in the form of a rod and a filter assembly 105. Filter assembly 105 includes three segments: cooling segment 107 , filter segment 109 , and mouth end segment 111 . Article 101 has a first end 113, also known as an oral or proximal end, and a second end 115, also known as a distal end. The body of aerosol-generating medium 103 is positioned toward the distal end 115 of article 101. In one example, cooling segment 107 is positioned adjacent to the body of aerosol-generating medium 103 between the body of aerosol-generating medium 103 and filter segment 109 such that cooling segment 107 It is in contact with 103. In other examples, there may be a spacing between the body of aerosol-generating medium 103 and cooling segment 107 and between the body of aerosol-generating medium 103 and filter segment 109. Filter segment 109 is positioned between cooling segment 107 and oral end segment 111. Mouth end segment 111 is positioned toward proximal end 113 of article 101 adjacent filter segment 109 . In one example, filter segment 109 is in abutting relationship with oral end segment 111. In one embodiment, the total length of the filter assembly 105 is between 37 mm and 45 mm, and more preferably the total length of the filter assembly 105 is 41 mm.

In one embodiment, the body of aerosol generating medium 103 includes tobacco. However, in other embodiments, the body of the aerosol-generating medium 103 may be composed solely of tobacco, or substantially entirely tobacco, such as tobacco and an aerosol-generating agent and/or flavoring agent. It may also contain other ingredients. In some cases, the aerosol generation medium may be tobacco-free.

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

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

The axial end of the body of aerosol generating medium 103 is visible at the distal end 115 of 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 body of the aerosol-generating medium 103.

The body of aerosol-generating media 103 is joined to filter assembly 105 by an annular tipping paper (not shown) that is disposed substantially around the entire circumference of filter assembly 105 to surround filter assembly 105. and extends partially along the length of the body of the aerosol generating medium 103. In one example, the tipping paper is made from 58 GSM standard tipping paper. In one example, the length of the chipping paper is between 42 mm and 50 mm, with 46 mm being suitable.

In one example, cooling segment 107 is an annular tube positioned around and defining a void within the cooling segment. The air gap provides a chamber for the flow of heated volatile components generated from the body of aerosol-generating medium 103. Although cooling segment 107 is hollow to provide a chamber for aerosol accumulation, it is still susceptible to axial compressive forces and bending that may occur when article 101 is inserted into device 51 during manufacturing and use. It is rigid enough to withstand moments. In one example, the wall thickness of cooling segment 107 is approximately 0.29 mm.

Cooling segment 107 provides physical spacing between aerosol generating media 103 and filter segment 109. This physical spacing provided by cooling segment 107 creates a thermal gradient across the length of cooling segment 107. In one example, the cooling segment 107 has a temperature difference of at least 40 degrees Celsius between the heated volatile component entering the first end of the cooling segment 107 and the heated volatile component exiting the second end of the cooling segment 107. It is configured to provide a temperature difference of 100 degrees. In one example, the cooling segment 107 has a temperature difference of at least 60 degrees Celsius between the heated volatile component entering the first end of the cooling segment 107 and the heated volatile component exiting the second end of the cooling segment 107. It is configured to provide a temperature difference of 100 degrees. This temperature difference across the length of the cooling element 107 when heated by the device 51 protects the temperature sensitive filter segment 109 from the high temperature of the aerosol generating medium 103. If no physical spacing is provided between the filter segment 109 and the body of the aerosol-generating medium 103 and the heating element of the device 51, the temperature-sensitive filter segment 109 may be damaged during use and thus , will not effectively perform the required function.

In one example, the length of 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 between 23 mm and 27 mm, more particularly between 25 mm and 27 mm, suitably 25 mm.

The cooling segment 107 is made of paper, meaning that it is constructed of a material that does not produce compounds of concern, e.g. toxic compounds, when in use next to the heater of the device 51. In one example, the cooling segment 107 is manufactured from a helically wound paper tube, which includes a hollow internal chamber but still maintains mechanical rigidity. Helically wound paper tubes can meet the stringent dimensional accuracy requirements of high speed manufacturing processes with respect to tube length, outer diameter, roundness, and straightness.

In another example, cooling segment 107 is a recess made from stiff plug web or chipping paper. The rigid plug web or tip paper is manufactured to have sufficient stiffness to withstand the axial compressive forces and bending moments that may occur during manufacture and use while the article 101 is inserted into the device 51. Ru.

Filter segment 109 may be formed from any filter material sufficient to remove one or more volatile compounds from heated volatile components from the aerosol generation medium. In one example, filter segment 109 is made from a monoacetate material such as cellulose acetate. Filter segment 109 cools the heated volatile components and reduces irritation from them without reducing the amount of heated volatile components to a level that is unsatisfactory to the user.

A collapsible capsule 5 is provided in the filter segment 109. The collapsible capsule 5 may be located substantially in the middle of the filter segment 109, ie centrally both in terms of the diameter of the filter segment 109 and the length of the filter segment 109. In other cases, the collapsible capsule 5 may be offset in one or more directions.

The density of the acetylcellulose tow material of filter segment 109 controls the pressure drop across filter segment 109 and thus the suction resistance of article 101. Therefore, the selection of the material for filter segment 109 is important in controlling the suction resistance of article 101. Additionally, the filter segments perform a filtration function in article 101.

In one example, the filter segment 109 is made of 8Y15 grade filter tow material, which provides a filtration effect on heated volatilized material and removes condensed aerosol droplets resulting from heated volatilized material. Reduce size.

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

In one example, the length of filter segment 109 is between 6 mm and 10 mm, with 8 mm suitably.

Oral end segment 111 is an annular tube that is disposed around and defines a void within oral end segment 111 . The air gap provides a chamber for heated volatile components flowing from filter segment 109. The oral end segment 111 is hollow to provide a chamber for aerosol accumulation, but is still susceptible to axial compressive forces that may occur during manufacture and when an article is inserted into the device 51 during use. and has sufficient rigidity to withstand bending moments. In one example, the wall thickness of oral end segment 111 is approximately 0.29 mm. In one example, the length of the oral end segment 111 is between 6 mm and 10 mm, with 8 mm suitably.

The oral end segment 111 may be manufactured from a helically wound paper tube, which includes a hollow internal chamber but still maintains ultimate mechanical rigidity. Helically wound paper tubes can meet the stringent dimensional accuracy requirements of high speed manufacturing processes with respect to tube length, outer diameter, roundness, and straightness.

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

In one example, oral end segment 111 and cooling segment 107 may be formed from a single tube, with filter segment 109 disposed within the tube to connect oral end segment 111 and cooling segment 107. Separation should be understood.

Referring to FIGS. 5 and 6, a partially cut away cross-sectional and perspective view of an example article 301 is shown. The reference numbers shown in FIGS. 5 and 6 are the same as the reference numbers shown in FIGS. 3 and 4 plus "200".

In the example article 301 shown in FIGS. 5 and 6, a ventilation area 317 is provided in the article 301 to allow air to flow from the exterior of the article 301 to the interior of the article 301. In one example, ventilation area 317 takes the form of one or more ventilation holes 317 formed through the outer layer of article 301. Ventilation holes may be placed in the cooling segment 307 to aid in cooling the article 301. In one example, the ventilation area 317 comprises one or more rows of holes, each row of holes arranged around the entire circumference of the article 301 in a cross-section substantially perpendicular to the longitudinal axis of the article 301. It is preferable.

In one example, there are one to four rows of ventilation holes to provide ventilation for the article 301. Each row of ventilation holes can have between 12 and 36 ventilation holes 317. The diameter of the ventilation hole 317 can be, for example, 100 μm to 500 μm. In one example, the axial spacing between rows of ventilation holes 317 is between 0.25 mm and 0.75 mm, with 0.5 mm being suitable.

In one example, ventilation holes 317 are uniformly sized. In another example, ventilation holes 317 are of different sizes. Ventilation holes can be created using any suitable technique, such as one or more of the following techniques: That is, laser technology, mechanical drilling of the cooling segment 307, or pre-drilling before forming the cooling segment 307 in the article 301. Ventilation holes 317 are arranged to effectively cool the article 301.

In one example, the row of ventilation holes 317 is located at least 11 mm from the proximal end 313 of the article, and suitably between 17 mm and 20 mm from the proximal end 313 of the article 301. The position of the ventilation hole 317 is arranged so that the user does not block the ventilation hole 317 when using the article 301.

As can be seen in FIGS. 8 and 9, by providing a row of ventilation holes 17 mm to 20 mm from the proximal end 313 of article 301, ventilation holes 317 are provided when article 301 is fully inserted into device 51. It can be placed outside the device 51. By placing the ventilation holes on the outside of the device, unheated air can enter the article 301 from outside the device 51 through the ventilation holes to help cool the article 301.

The length of cooling segment 307 is such that when article 301 is fully inserted into device 51, cooling segment 307 is partially inserted into device 51. The length of the cooling segment 307 serves the primary function of providing a physical gap between the heater arrangement of the device 51 and the heat sensitive filter arrangement 309 and the length of the cooling segment 307 so that the article 301 is completely inserted into the device 51. When installed, the ventilation hole 317 is located within the cooling segment, but also provides a second function of allowing it to be located outside the device 51 as well. As can be seen in FIGS. 8 and 9, the majority of the cooling element 307 is located within the device 51. However, a portion of cooling element 307 extends outside of device 51. Ventilation holes 317 are located in this part of the cooling element 307 that extends out from the device 51.

7-9 in more detail, the aerosol-generating medium is typically used to form an aerosol that can be inhaled to volatilize at least one component of the aerosol-generating medium. An example of a device 51 configured to heat is shown. Device 51 is a heating device that releases the compound by heating the aerosol generating medium without burning it.

First end 53 is also referred to herein as the oral or proximal end 53 of device 51, and second end 55 is also referred to herein as distal end 55 of device 51. Device 51 has an on/off button 57 that allows the user to turn the entire device 51 on and off as desired.

Device 51 includes a housing 59 for locating and protecting various internal components of device 51. In the illustrated example, the housing 59 includes an integral sleeve 11 that surrounds the device 51, including a top panel 17 that generally defines the "top" of the device 51, and a bottom panel 19 that generally defines the "bottom" of the device 51. is covered with In another example, the housing includes a top panel 17 and a bottom panel 19, as well as a front panel, a rear panel, and a pair of opposing side panels.

The top panel 17 and/or bottom panel 19 may be removably secured to the integral sleeve 11 to allow easy access to the interior of the device 51 or, for example, to allow a user to access the interior of the device 51. It may be "permanently" fixed to the integral sleeve 11 so that the interior cannot be accessed. In one example, panels 17 and 19 are made from a plastic material including, for example, glass-filled nylon formed by injection molding, and integral sleeve 11 is made from aluminum, although other materials and other manufacturing processes may be used. You can.

The top panel 17 of the device 51 has an opening 20 at the oral end 53 of the device 51 through which, in use, a user inserts an article 101, 301 containing an aerosol-generating medium into the device 51. It can also be removed from the device 51.

A heater component 23, a control circuit 25, and a power source 27 are arranged or fixed within the housing 59. In this example, heater arrangement 23, control circuit 25, and power supply 27 are laterally adjacent (i.e., (adjacent when viewed from one end), but other positions are also possible.

Control circuit 25 may include a controller, such as a microprocessor arrangement, constructed and arranged to control heating of the aerosol-generating medium of article 101, 301, as discussed further below.

Power source 27 may be, for example, a battery, which may be a rechargeable battery or a non-rechargeable battery. Examples of suitable batteries include, for example, lithium ion batteries, nickel batteries (such as nickel-cadmium batteries), and/or alkaline batteries. The battery 27 is used to provide electrical power when needed and to heat the aerosol-generating medium of the article under the control of the control circuit 25 (as described above, without burning the aerosol-generating medium). (for volatilization) and is electrically connected to a heater arrangement 23.

The advantage of locating power supply 27 side-by-side with heater arrangement 23 is that a physically larger power supply 25 can be used without making the overall device 51 too long. As will be appreciated, a physically larger power source 25 will generally have a greater capacity (i.e., total electrical energy that it can provide, often measured in ampere-hours, etc.) and, therefore, a physically larger power source 25 battery life can be extended.

In one example, the heater arrangement 23 is generally in the form of a hollow cylindrical tube having a hollow internal heating chamber 29 such that, in use, the article 101, 301 with the aerosol-generating medium is placed within the heating chamber 29 under heating. inserted for. Different configurations of heater arrangement 23 are possible. For example, heater arrangement 23 may include a single heating element or may be formed from a plurality of heating elements aligned along the longitudinal axis of heater arrangement 23. The or each heating element may be annular or tubular or at least partially annular or partially tubular in 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 from a ceramic material. Examples of suitable ceramic materials include alumina, aluminum nitride, and silicon nitride ceramics, which may be laminated and sintered. Other heating arrangements are possible, including, for example, induction heating, infrared heating elements that heat by emitting infrared radiation, or resistive heating elements, for example formed by resistive electrical windings.

In one particular example, heater arrangement 23 is supported by a stainless steel support tube and includes a polyimide heating element. The heater arrangement 23 is configured such that when the article 101 , 301 is inserted into the device 51 , substantially the entire body of the aerosol generating medium 103 , 303 of the article 101 , 301 is inserted into the heater arrangement 23 . The dimensions are as follows.

This or each heating element may independently heat selected regions of the aerosol-generating medium, e.g. in sequence (over time, as described above) or together (simultaneously), as desired. It can be configured to do so.

The heater arrangement 23 in this example is surrounded by insulation 31 along at least part of its length. Insulation 31 helps reduce heat flowing from heater arrangement 23 to the exterior of device 51. This generally reduces heat losses and thus helps keep power requirements to heater arrangement 23 low. Insulation 31 also helps keep the outside of device 51 cool during operation of heater arrangement 23. In one example, the insulation 31 may be a double-walled sleeve with a low pressure region between the two walls of the sleeve. That is, the insulation 31 may be, for example, a "vacuum" tube, ie, a tube that is at least partially evacuated to minimize heat transfer by conduction and/or convection. Other configurations of the insulation 31 are possible, including the use of insulating materials, including, for example, suitable foam-type materials in addition to or instead of a double-walled sleeve.

Housing 59 may further include various internal support structures 37 to support not only heating arrangement 23 but all internal components.

Device 51 includes a collar 33 extending around opening 20 and projecting from opening 20 into the interior of housing 59 and a generally tubular chamber 35 disposed between collar 33 and one end of vacuum sleeve 31. Be prepared for more. Chamber 35 further includes a cooling structure 35f, which in this example is spaced apart along the outer surface of chamber 35, each of which is arranged circumferentially around the outer surface of chamber 35. Cooling fins 35f are provided. There is an air gap 36 between the hollow chamber 35 and the article 101, 301 when the article 101, 301 is inserted into the device 51 over at least a portion 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 a portion of the cooling segment 307.

The collar 33 includes a plurality of ridges 60 circumferentially arranged around the opening 20 , the ridges 60 projecting into the opening 20 . The ridge 60 occupies a space within the aperture 20 such that the aperture span of the aperture 20 at the location of the ridge 60 is narrower than the aperture span of the aperture 20 at the location without the ridge 60. There is. The ridges 60 are configured to engage an article 101 , 301 inserted into the device to help secure the article 101 , 301 within the device 51 . An open space (not shown) defined by the pair of adjacent ridges 60 and the article 101,301 forms a ventilation passageway around the outside of the article 101,301. These ventilation passages allow hot steam leaking from the articles 101 , 301 to exit the device 51 and also allow cooling air to flow into the device 51 from around the articles 101 , 301 in the air gap 36 . enable.

In operation, the article 101, 301 is removably inserted into the insertion point 20 of the device 51, as shown in FIGS. 7-9. With particular reference to FIG. 8, in one example, the body of the aerosol-generating medium 103, 303 disposed toward the distal end 115, 315 of the article 101, 301 is completely contained within the heater arrangement 23 of the device 51. has been done. Proximal ends 113, 313 of articles 101, 301 extend from device 51 to serve as a mouthpiece assembly for the user.

In operation, heater arrangement 23 heats article 101, 301 to volatilize at least one component of the aerosol-generating medium from the body of aerosol-generating medium 103, 303.

The main flow path for the heated volatile components from the body of the aerosol-generating medium 103, 303 passes axially through the article 101, 301, through the inner chamber of the cooling segment 107, 307, through the filter segment 109, 309 and through the oral end segments 111, 313 to the user. In one example, the temperature of the heated volatile components produced from the body of the aerosol-generating medium is between 60° C. and 250° C., which may be higher than the suction temperature acceptable to the user. As the heated volatile components move through the cooling segments 107, 307, their temperature decreases and some of the volatile components condense on the inner surfaces of the cooling segments 107, 307.

In the example article 301 shown in FIGS. 5 and 6, cold air may enter the cooling segment 307 through ventilation holes 317 formed in the cooling segment 307. This cool air mixes with the heated volatile components and further cools the heated volatile components.

As the article is heated by device 51 during use, this ventilation facilitates the production of heated, volatile visible components from article 317. The heated volatile component is visualized by a process of cooling the heated volatile component such that supersaturation of the heated volatile component occurs. The heated volatile components then undergo droplet formation, also known as nucleation, which ultimately results in further condensation of the heated volatile components and newly formed droplets from the heated volatile components. Coagulation of the droplets increases the size of the aerosol particles of heated volatile components.

In one embodiment, the ratio of cold air to the sum of heated volatile components and cold air, known as the ventilation rate, is at least 15%. If the ventilation rate is 15%, the vaporized components heated by the above method can be visualized. When the heated volatilized components are visualized, the user is aware that the volatilized components have been produced, and this adds to the sensory experience of the smoking experience.

In another example, the ventilation rate is between 50% and 85% to further cool the heated volatile components.
