Description

The technical field to which the invention relates

The invention relates to an article of the "heat but not burn" type and a device for heating without burning.

State of the art

In articles such as cigarettes, cigars and the like, tobacco is burned in use to create tobacco smoke. As an alternative to these combustible articles, a respirable aerosol is generated by heating the base material.

These products can generally be referred to as aerosol generating devices. Examples of such devices are so-called “heat but not burn” products, also called tobacco heating products or tobacco heating devices, in which compounds are released by heating without burning the base material to form a respirable aerosol. This material can be, for example, tobacco or other non-tobacco product or a combination such as a composite blend, wherein said material may or may not contain nicotine.

Disclosure of invention

The first object of the invention is a product of the "heat but not burn" type, containing an aerosol-forming material and a filter with one or more breakable capsules, made so that when heated without burning the aerosol-forming material, the capsule is exposed to a temperature of about 30-100 ° C, and during This action does not compromise the structural integrity of the capsule, so that the capsule can be destroyed by the user before heating, during heating, or after heating.

Implementation of the invention

In accordance with the first aspect of the invention, the article of the "heat but not burn" type contains an aerosol-forming material and a filter with one or more breakable capsules, made so that when heated without burning the aerosol-forming material, the capsule is exposed to a temperature of about 30-100 ° C, and in During this action, the structural integrity of the capsule is not compromised, so that the capsule can be destroyed by the user before heating, during heating, or after heating.

The aerosol generated by the heat-not-burn product is generally warm and humid due to the nature of the heating profile and the composition of the aerosol-forming material. For example, the aerosol-forming material in a heat-but-burn-type article of the invention may contain a higher proportion of the aerosol-generating material than the smoking material used in a combustible article. The aerosol-forming material in a heat-but-not-burn article of the invention may be heated to a high temperature and / or for a longer period than the combustion temperature or period for the combustible article. It has been found that the capsules described in claim 1 are particularly suitable for use in a heat-not-burn product. Such capsules have been found to be less likely to fail or rupture when exposed to heat-but-burn conditions in a product than other capsules.

In some cases, in use, the aerosol material generates a wet aerosol and the capsule is exposed to at least 12 mg of water.

The temperature profile of the center of the filter has been found to peak during each puff during use. This is because when puffed, hot aerosol is drawn in through the filter. In some cases, the capsule may be exposed to temperatures in excess of about 30, 40 or 50 ° C. In some cases, the maximum temperature the capsule is exposed to during use is less than about 100, 90, 80, or 70 ° C. In some cases, the capsule can be exposed to temperatures in the range of 30-100 ° C, preferably in the range of 40-80 ° C or 50-70 ° C.

As used herein, the term “heat but not burn” article refers to an article that contains an aerosol-forming material; and in use, the components of the aerosol-forming material are vaporized by heating without burning or incineration, forming a respirable vapor or aerosol.

The heat-but-burn-type aerosol material of a product contains a solid component (as opposed to the aerosol-forming material in electronic cigarettes, in which the aerosol-forming material is a liquid). By "solid" material is meant that the material does not flow when it is in a steady state. Solid material can encompass gels and the like. To avoid ambiguity, the aerosol-forming material in a heat-but-not-burn article may contain, in addition to the solid component, a liquid component.

The capsule according to the invention 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 flavors. In some cases, the core may contain acid, base and / or water. In some cases, the core may contain a solvent. In some specific cases, the core may contain menthol.

A capsule shell material (which may alternatively be called a barrier material or encapsulating material) encapsulates the core in a capsule. The shell material, in some cases, can serve to minimize the movement of the core during storage of the goods. The sheath material can provide a controlled output of the core in use. The capsule can be ruptured (ie, destroyed) to release the contents prior to heating, during heating, or after heating the "heat but not burn" article.

The capsule shell material is destructible, that is, it is brittle or damaged. The user destroys or otherwise ruptures or damages the capsule in order to release the contents. Usually, the capsule is damaged just before heating starts, but the user can choose when to release the contents (it can be destroyed after heating starts). The term "breakable capsule" refers to a capsule in which the encapsulating material (which may be the shell) can be damaged by pressure to release the encapsulated material (which may be the capsule core). More specifically, the encapsulating material (eg, shell) can be ruptured under pressure provided by the user's fingers (or any other means of creating pressure) when the user wishes to release the contents of the capsule. In some cases, the capsule may have an initial (before heating) fracture strength of about 0.8 to 3.5 kgf, preferably 1.0 to 2.5 kgf, or about 1.0 to 2.0 kgf. Capsules may lose strength when heated. It was found that capsules, the initial breaking strength of which is not less than 0.8 kgf, are less likely to break / rupture when heated. It has been found that capsules with a breaking strength greater than 3.5 kgf are difficult to break before heating. It has been found that an initial fracture strength of 1.0 to 2.0 kgf provides the best capsule performance.

In some cases, the capsules of the invention may be substantially spherical with a diameter of about 0.4, 0.6, 0.8, 1.0, 2.0, 2.5, 2.8 or 3.0 mm. The capsule diameter can be less than about 10.0, 8.0, 7.0, 6.0, 5.5, 5.0, 4.5, 4.0, 3.5, or 3.2 mm. For example, the diameter of the capsule can range from about 0.4 to 10.0 mm, from about 0.8 to 6.0 mm, from about 2.5 to 5.5 mm, or from about 2.8 to 3, 2 mm. In some cases, the capsule diameter can be from about 3.0 to 3.5 mm. These dimensions are particularly suitable for placing the capsule in a heat-but-burn-type product filter.

In some cases, the total weight of the described capsule may range from about 1 to 100 mg, preferably from 5 to 60 mg, 10 to 50 mg, 15 to 40 mg, or 15 to 30 mg.

In some cases, the total weight of the core composition may range from about 2 to 90 mg, preferably from about 3 to 70 mg, 5 to 25 mg, 8 to 20 mg, or 10 to 15 mg.

The shell contains a gelling agent in an amount of 5-90% by weight based on the total weight of the capsule shell, wherein the gelling agent contains, consists of, or essentially consists of carrageenan. In some cases, the shell contains the specified gelling agent in an amount of 5-60%, 5-50% or 10-35% by weight, based on the total weight of the capsule shell. In some cases, the gelling agent in the capsule shell contains carrageenan. In some cases, the melting point of this carrageenan is at least about 30 ° C or 40 ° C.

In addition to carrageenan, the shell may contain additional gelling agents. Suitable gelling agents that may be contained in the capsule shell material may be polysaccharide or cellulose gelling agents, gelatins, gums, gels, waxes, or mixtures thereof. Suitable polysaccharides are alginates, dextrans, maltodextrins, cyclodextrins and pectins. Suitable alginates are, for example, an alginic acid salt, an alginate ester or a glycerol alginate. Alginic acid salts include ammonium alginate, triethanolamine alginate, and alginate salts of Group I or II metal ions such as sodium, potassium, calcium and magnesium alginate. Alginate esters include propylene glycol alginate and glycerol alginate. In some examples, the barrier material contains sodium alginate and / or calcium alginate. Suitable cellulosic materials are methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose, cellulose acetate, and cellulose ethers. The gelling agent may contain one or more modified starches. The gelling agent may contain one or more carrageenans. Suitable gums are agar, gellan gum, gum arabic, pullulan gum, mannan gum, ghatti gum, gum tragacanth, karaya gum, locust bean, Senegalese gum, guar, quince seeds and xanthan gum. Suitable gels are agar, agarose, carrageenans, fucoidan, and furcellaria. A suitable wax is, for example, carnauba wax. In some cases, the gelling agent may contain carrageenans and / or gellan gum; these gelling agents are particularly suitable for placement as gelling agents because the result is a pressure which is particularly suitable for breaking the resulting capsules. In some cases, the capsule shell does not contain gelatin.

The capsule shell may additionally contain one or more of the following substances: a bulking agent, a buffer, a coloring agent and a plasticizer.

In some cases, the capsule shell material may contain one or more bulking agents 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 colorant that more easily denotes the location of the capsule in the tobacco product during manufacture. Preferably, the colorant is selected from dyes and pigments.

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

In some cases, the capsule shell material may further comprise at least one plasticizer, which may be glycerin, sorbitol, maltitol, triacetin, polyethylene glycol, propylene glycol, or other polyalcohol with plasticizer properties, and, if desired, one acid of the monobasic, dibasic or tribasic type, in particular citric acid, fumaric acid, malic acid and the like. In some cases, the amount of plasticizer is in the range of 1 to 30% by weight, preferably 2 to 15% by weight, and more preferably 3 to 10% by weight, based on the total weight of the shell. In some cases, the total amount of plasticizer and gelling agent in the shell is about 40-70%, suitably 50-60%, by weight, based on the total weight of the capsule shell. In some cases, the plasticizer contains, consists of, or essentially consists of glycerin.

In some cases, the capsule shell may also contain one or more filler materials. Suitable filler materials are starch derivatives such as dextrin, maltodextrin, cyclodextrin (alpha, beta or gamma) or cellulose derivatives such as hydroxypropyl methylcellulose (HPMC), hydroxypropyl cellulose (HPC), methyl cellulose (MC), carboxymethyl cellulose (CMC), polyvinyl alcohol , polyhydric alcohols or a mixture thereof. The capsule shell may contain, in some cases, filler in an amount up to about 60% by weight based on the total weight of the capsule shell. In some cases, the capsule shell may contain filler in an amount of up to about 50, 40, 30, or 20% by weight based on the total weight of the capsule shell. In some specific cases, the capsule shell may contain no filler.

The capsule shell may further comprise a hydrophobic outer layer that reduces the capsule's susceptibility to moisture degradation. The hydrophobic outer layer is suitably selected from the group containing waxes, especially carnauba wax, candelilla wax or beeswax, carbovax, shellac (in alcoholic or aqueous solution), ethylcellulose, hydroxypropyl methylcellulose, hydroxylpropylcellulose, latex mixture, polyvinyl alcohol, or a combination thereof. More preferably, the at least one moisture barrier is ethylcellulose or a mixture of ethylcellulose and shellac.

The methods for making capsules are co-extrusion, if desired, complemented by configuring and curing and / or drying. These and other suitable techniques are known in the art.

The filter may contain filter material. For example, the filter can contain cellulosic material such as cellulose acetate, ceramic material, polylactic acid, polymer matrix, and / or activated carbon. Suitable examples of ceramic materials are silicon carbide (SiC), silicon nitride (Si ₃ N ₄ ), titanium carbide and zirconia.

In some cases, the average melting point of the filter media is at least about 150 ° C. When used in an aerosol generating device, the filter is generally exposed to temperatures not exceeding 150 ° C; so that in such embodiments the filter does not melt and supports the capsule well. This assists the user wishing to rupture the capsule after heating has started. In some cases, the average melting point of the filter media is at least about 160, 170, 180, 190, or 200 ° C.

In some cases, the average thermal conductivity of the filter material is at least 0.130 W / (m · K). This has been found to help the user wishing to break the capsule after heating has started. In some cases, the average thermal conductivity of the filter material is at least 0.140 W / (m · K), 0.150 W / (m · K), or 0.160 W / (m · K).

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

In some cases, the capsule fills approximately 5-30% of the filter by volume. In some cases, the filter contains filter material, suitably cellulose acetate, in an amount of 70-95% by volume. It has been found that these proportions result in proper absorption of heat by the capsule.

In some cases, the filter is substantially cylindrical and the capsule is substantially centered with respect to the diameter of said cylinder. In some cases, the capsule is located substantially centered on the length of the cylinder. In some cases, the length of the cylindrical filter may be about 8-14 mm, suitably 9-13 mm or 10-12 mm. The cross-sectional diameter of the filter can be about 5-9 mm, suitably 7.5-8 mm. It can be made from cellulose acetate fibers.

In some cases, when the capsule is intact, the pressure drop across the filter upon inhalation of the user is in the range of 30 to 90 mmH ₂ O. It is advisable that the pressure drop across the filter could be in the range of about 30, 33, 35, 38, or 40 mmH ₂ O to about 90, 75, 65, 60, 55, or 50 mmH ₂ O when the capsule is intact. For example, the pressure drop across the filter when the capsule is intact can be in the range of about 35-60 mmH ₂ O, preferably 38-55 mmH ₂ O or 40-50 mmH ₂ O.

In some cases, the filter contains only one capsule. In other cases, the filter contains more than one capsule. When the filter contains several capsules, the individual capsules may be the same or different from each other. For example, if there are multiple capsules, the user can select when / which capsule to damage, thereby controlling the aerosol delivery profile.

In some cases, the aerosol forming material contains an aerosol generating agent. In some cases, the aerosol generating material contains tobacco material. In some cases, the aerosol generating material contains a fragrance. In some cases, the aerosol generating material consists or essentially consists of an aerosol generating agent and / or tobacco material and / or flavoring. In some cases, the aerosol generating material may be a single, integral component. In other cases, the aerosol generating material may contain separate sections that contain different compositions. For example, the aerosol generating material may contain an aerosol generating agent and a tobacco material, and these may be located in separate different sections of the aerosol forming material.

In some embodiments, the capsule contains a flavor and the aerosol-forming material contains a flavor, the flavor is substantially the same in both cases. This can help deliver a more consistent flavor profile. In some cases, the capsule contains menthol and the aerosol material contains menthol.

As used herein, the term "tobacco material" refers to any material containing tobacco or its derivatives. The tobacco material may include one or more of the following: tobacco, tobacco derivatives, exploded tobacco, reconstituted tobacco, or tobacco substitutes. The tobacco material may contain one or more of the following materials: ground tobacco, tobacco fiber, shredded tobacco, compressed tobacco, tobacco stem, reconstituted tobacco, and / or tobacco extract.

The tobacco used to make the tobacco material can be any suitable tobacco such as single-grade tobacco or tobacco blends, cut or whole leaf tobacco, including Virginia and / or Burley tobacco and / or Oriental tobacco. It can also be "fine" tobacco particles or tobacco dust or exploded tobacco, stems, exploded stems, or other treated stem materials such as cut and rolled stems. The tobacco material can be ground tobacco or reconstituted tobacco material. The reconstituted tobacco material can contain tobacco fibers and can be made by casting, a long mesh papermaking approach with added tobacco extract, or by extrusion.

As used herein, the term "aerosol generating agent" is a substance that promotes aerosol production. The aerosol generating agent can promote aerosol production by promoting the initial vaporization and / or condensation of the gas into a respirable particulate and / or liquid aerosol.

Suitable aerosol generating agents are: a polyol such as sorbitol, glycerol, or glycols such as propylene glycol or triethylene glycol; non-polyol such as monohydric alcohols, hydrocarbons with a high boiling point, acids such as lactic acid, derivatives of glycerol compounds, esters such as diacetin, triacetin, triethylene glycol diacetate, triethyl citrate or myristates, including ethyl myristate and isopropyl myristate, and aliphatic carbon esters acids such as methyl stearate, dimethyldodecanedioate and dimethyltetradecanedioate. In some cases, the aerosol generating agent may contain glycerin and / or propylene glycol.

In some cases, the aerosol generating material contains the aerosol generating agent in an amount of at least 10% by weight based on the total weight of the aerosol generating material. Suitably, the aerosol generating material contains the aerosol generating material in an amount of at least 12, 15, 18 or 20% by weight based on the total weight of the aerosol generating material. In some cases, the residue may be tobacco material.

In some cases, a heat-but-not-burn article may be substantially cylindrical.

In some cases, a “heat but not burn” product may additionally contain a cooling element. It can be located, for example, between the filter and the aerosol-forming material. A cooling element, if present, separates the filter from the hottest parts (in use) of the heat-not-burn product. The cooling element, if present, may comprise a free tube, which is preferably made of paper. The vaporized components of the aerosol forming material may condense, forming, when used, an aerosol in the cooling element (if present).

A heat but do not burn product may additionally contain ventilation holes. They can be located in the side walls of the product. In some cases, ventilation holes can be provided in the filter and / or in the cooling element. These openings allow the air to be drawn into the product during use to be cooled, while the air is mixed with the heated vaporized components, thereby cooling the aerosol.

Ventilation improves the production of visible heated vaporized components from the product when it is heated. The heated vaporized components are made visible by the cooling process of the heated vaporized components as the heated vaporized components become oversaturated. The heated evaporated components then undergo a droplet formation process, also known as active site formation, and ultimately the aerosol particle size of the heated evaporated components increases due to additional condensation of the heated evaporated components and due to the coalescence of newly formed droplets from the heated evaporated components.

In some cases, the ratio of the cooling air to the sum of the heated evaporated components and the cooling air, which is called the ventilation ratio, is at least 15%. A ventilation ratio of 15% allows the heated vaporized components to become visible through the process described above. The visibility of the heated vaporized components allows the user to determine that vaporized components have been produced and adds a sensory experience to the smoking experience.

In another example, the ventilation ratio is 50 to 85% to provide additional cooling for the heated vaporized components.

In the present description, the term “non-combustion heating device” is to be understood as a combination of a “heat but not burn” article and a heater. The heater heats the aerosol-forming material in the heat-but-burn-type article without burning it in order to vaporize the base components and generate respirable vapor or aerosol.

In some cases, the heater can be made in one piece with the product. For example, the heater may be a combustible source of combustible material that is attached to an article such that, in use, combustion of the combustible material source heats the aerosol-forming material without combusting the material. In another example, the heater may comprise a chemical heat source, such as a phase change material, that goes through an exothermic reaction to generate heat.

In other cases, the heater may be a separate object that is configured for use with an article. For example, the heater can be a device into which a "heat but not burn" article is inserted at least partially. In another example, the heater may be a device that is at least partially inserted into a “heat but not burn” article. The heater can be controlled electrically. In some cases, the heater comprises a thin film, an electric resistance heater, an induction heater, or the like.

In some cases, the device may be configured such that at least a portion of the aerosol-forming material in the "heat but not incinerate" article is exposed to a temperature of 180 to 200 ° C for at least 50% of the heating period. In some examples, the aerosol-forming material may be exposed to a heat profile as described in PCT / EP2017 / 068804, the contents of which are incorporated herein by reference in their entirety.

In some specific cases, the non-combustion heating device is configured to separately heat two portions of the aerosol-forming material. By controlling the temperature of the first and second portions over time, at different temperature profiles of those portions, the puff profile for the aerosol in use can be controlled. The heat provided to the two portions of the aerosol forming material can be provided at different times or at different rates. Thus, staged heating can provide both rapid aerosol production and greater durability.

In one specific example, the non-combustion heating device may be configured such that at the start of the consumption period, the first heating element corresponding to the first portion of the aerosol-forming material is rapidly heated to a temperature of 240 ° C. This first heating element is kept at 240 ° C for 145 seconds and then this temperature drops to 135 ° C (and remains for the remainder of the consumption period). 75 seconds after the start of the consumption period, the second heating element corresponding to the second portion of the aerosol-forming material is heated to a temperature of 160 ° C. 135 seconds after the start of the consumption period, the temperature of the second heating element rises to 240 ° C (and remains for the remainder of the consumption period). The consumption period lasts 280 seconds, after which both heaters are cooled down to room temperature.

In some cases, the non-combustion heating device is configured such that the filter of the “heat but not burn” article is not directly heated. For example, when the heater is a device into which an article is partially inserted, the non-combustion heating device may be configured such that a heat-but-not-burn article filter is not inserted into the device.

In some specific cases, the device is designed such that the filter and cooling element, if present, of the “heat but not burn” product are not directly heated. For example, when the heater is a device in which an article is partially inserted, the non-combustion heating device may be configured such that the filter and cooling element, if present, of the heat but not burn article are not inserted into the device. In other cases, at least part of the cooling element can be inserted into said device.

In such cases, even if the filter is not directly heated, heat will pass through the “heat but not burn” product during the consumption period (when the user puffs). The temperature profile of the center of the filter has been found to have peaks during each puff. This is because when puffed, hot aerosol is drawn in through the filter. In some cases, the filter (and capsule) may be exposed to temperatures in excess of about 30, 40 or 50 ° C. In some cases, the maximum temperature that the filter (and capsule) is exposed to during use does not exceed approximately 100, 90, 80 or 70 ° C. In some cases, the filter (and capsule) may be exposed to temperatures in the range of 30-100 ° C, suitably in the range of 40-80 ° C or 50-70 ° C.

It has been found that the capsules according to the invention are particularly suitable for use in a "heat but not burn" article. Even though the capsules may in some cases be exposed to temperatures above the shell melting point or glass transition temperature, the capsules of the invention are less likely to fail or rupture when exposed to conditions in a heating device without burning compared to other capsules. Such capsules can be easily broken by the user before heating, during heating, or after heating has started to release the contents of the capsules. In this case, the capsules create a clicking sensation upon destruction, which provides tactile feedback to the user, indicating that the destruction has taken place. This clicking sensation is beneficial as the user then knows that sufficient pressure has been applied and the contents of the capsule are released. It is unlikely that excessive pressure will be applied, which can damage the product "heat, but do not burn".

The suitability of the disclosed capsules for use in a "heat but not burn" product is due to the composition of the shell material and the absorption of water. Other factors that may relate to this are the heat capacity of the shell material, the melting or glass transition temperature of the shell material, and / or the distance from the capsule to the heater.

In some cases, the capsule may be positioned in the "heat but not burn" article such that the distance from the heater in the non-fired heating device is at least about 25 mm or at least about 30 mm. In some cases, the capsule may be positioned in a “heat but not burn” article such that the distance from the heater is about 25-30 mm or about 30-35 mm (these distances are the distance from the center of the capsule to the nearest point on the heater). This arrangement means that the capsule is exposed to the correct level of heat while maintaining the proper dimensions for the “heat but not burn” product.

Capsules made from a shell material that contains carrageenan and which has a melting point of at least 30 ° C or 40 ° C have been found to withstand well the heat but not burn product conditions.

One embodiment of a "heat but not burn" product is shown in FIG. 1. This product has a substantially cylindrical shape. It may comprise a rod of aerosol-forming material, preferably tobacco, located towards the first end 2, and a filter 3, located towards the second end 4. The second end 4 is the mouth end. The capsule 5 is located in the filter 3. The filter 3 contains a filter material, which may be cellulose acetate. The paper wrap 6 retains the components in a cylindrical configuration and provides a passage 7 between the tobacco rod 1 and the filter rod 3. The passage 7 acts as a cooling element and may be omitted in alternative embodiments. There is an additional short passage between the filter rod 3 and the second end 4. In alternative embodiments of the invention, it may also be absent.

In use, the “heat but not burn” article 10 is partially inserted into the heater of a non-burning heating device (not shown) so that the article can be heated to form a respirable aerosol. In one embodiment, the heater forms an oven-like structure around the aerosol generating material. In some embodiments, the first end 2 of the "heat but not burn" article 10 is inserted such that the aerosol material 1 is located in the heater. The article 10 of the "heat but not burn" type and the device for heating without burning are made so that the filter 3 and at least part of the passage 7 are not located in the heater.

In alternative embodiments of the invention, the substantially cylindrical heat-but-not-burn article may contain aerosol-forming material 1 that is directly adjacent to the filter 3, and the passageway may be located on the opposite side of the filter relative to the specified material, or this passage may be absent.

After use, the “heat but do not burn” product is removed from the heater and is usually disposed of. With further use, other products of the "heat but do not burn" type are inserted into the heater.

An alternative non-combustion heating device is shown in FIG. 2. In this device for heating without combustion, a combustible heat source 8 is arranged next to the aerosol-forming material 1 at the first end 2 of the article 10 of the "heat but not burn" type. The combustible heat source 8 can be separated from the aerosol-forming material 1 by a non-combustible material (not shown) such as a layer of aluminum foil. Aluminum foil or other heat-conducting non-combustible materials, firstly, conduct heat to the aerosol-forming material, and, secondly, prevent the combustion of the source of combustible material, as a result of which the aerosol-forming material ignites. For use, the user ignites a source of combustible material 8 and heat is transferred by means of an aluminum foil (or the like) to the aerosol-forming material 1 to vaporize the components of this material without burning it.

FIG. 3 and 4 show another example of a heat-but-not-burn article 101, which is similar to the article shown in FIG. 1. Product 101 is adapted for use with a device comprising a power source and a heater. The article 101 is particularly suitable for use with the device 51 shown in FIG. 7-9 and described below. In use, the article 101 can be removably inserted into the device shown in FIG. 7, in place 20 of the device 51.

The article 101 is made in the form of a substantially cylindrical rod, which contains a volume of aerosol-forming material 103 and a collection filter 105, also in the form of a rod. The filter assembly 105 comprises three segments: a cooling segment 107, a filtration segment 109, and a mouth segment 111. The article 101 comprises a first end 113, also called a mouth or proximal end, and a second end 115, also called a distal end. The volume of aerosol material 103 is disposed towards the distal end 115 of the article 101. In one example, the cooling segment 107 is located adjacent to the volume of aerosol material 103 between the volume of this material 103 and the segment 109 of filtration, so that the segment 107 of cooling is adjacent to the material 103 and the segment 109 of filtration ... In other examples, the volume of aerosol material 103 and the cooling segment 107 can be separated, and the volume of aerosol material 103 and the filtration segment 109 can be separated. The filtration segment 109 is located between the cooling segment 107 and the mouth segment 111. The mouth segment 111 is located towards the proximal end 113 of the article 101 next to the filtration segment 109. In one example, the filtration segment 109 is adjacent to the mouth segment 111. In one embodiment, the overall length of the filter collection 105 is 37 to 45 mm, more preferably 41 mm.

The volume of aerosol material 103 may contain tobacco. However, in other cases, the bulk of aerosol forming material 103 may be tobacco, may be substantially tobacco only, may contain tobacco and other components such as aerosol and / or flavoring agent. In some cases, the aerosol material may be tobacco free.

In one example, the length of the rod of aerosol forming material 103 is 34 to 50 mm, preferably 38 to 46 mm, in particular 42 mm.

In one example, the total length of article 101 is 71 to 95 mm, suitably 79 to 87 mm, preferably 83 mm.

The end face of the volume of aerosol material 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) covering the end face of the volume of the aerosol material 103.

The volume of aerosol forming material 103 is connected to the collection filter 105 by an annular rim paper (not shown) that is substantially around the circumference of the collection filter 105, surrounding it, and partially extends along the length of the volume of aerosol forming material 103. In one example, the rim paper is made of a rim base papers of 58GSM standard. In one example, the length of the tipping paper is 42 to 50 mm, in particular 46 mm.

In one example, the cooling segment 107 is an annular tube and creates an air gap within the cooling segment. The air gap forms a chamber for the flow of heated vaporized components generated from the volume of aerosol-forming material 103. The cooling segment 107 is hollow and forms a chamber for accumulating aerosol, yet it is rigid enough to withstand the axial compressive forces and bending moments that can occur during manufacture and when the article 101 is inserted into the device 51. In one example, the wall thickness of the cooling segment 107 is about 0.29 mm.

The cooling segment 107 provides a physical distance between the aerosol forming material 103 and the filtration segment 109. The physical distance provided by the cooling segment 107 will create a temperature difference along the length of the cooling segment 107. In one example, the cooling segment 107 is configured to provide a temperature difference of at least 40 ° C between the heated vaporized component entering the first end of the cooling segment 107 and the evaporated component exiting the second end of the cooling segment 107. In one example, the cooling segment 107 is configured to provide a temperature difference of at least 60 ° C between the heated vaporized component entering the first end of the cooling segment 107 and the evaporated component exiting the second end of the cooling segment 107. This temperature difference along the length of the cooling element 107 protects the temperature sensitive filtration segment 109 from the high temperatures of the aerosol material 103 when heated by the device 51. If no physical distance is provided between the filtration segment 109 and the volume of aerosol material 103 and the heating elements of the device 51, the temperature sensitive filtration segment 109 can be damaged in use without performing its function as efficiently as required.

The length of the cooling segment 107 is at least 15 mm. For example, the length of the cooling segment 107 may be 20 to 30 mm, preferably 23 to 27 mm, more preferably 25 to 27 mm, suitably 25 mm.

The cooling segment 107 is made of paper, i. E. from a material that does not generate problematic compounds, such as toxic, when used near the heater of the device 51. In one example, the cooling segment 107 is made of a coiled paper tube to form a hollow inner chamber that nonetheless maintains mechanical rigidity. Spirally wound paper tubes are capable of meeting stringent dimensional accuracy requirements for tube length, outer diameter, roundness and straightness for high speed fabrication processes.

In another example, the cooling segment 107 is a recess made of stiff ficella or tipping paper. Rigid fitzella or rim paper is made to have sufficient rigidity to withstand the axial compressive forces and bending moments that can occur during manufacture and when the article 101 is inserted into the device 51.

The filtration segment 109 can be made of any filter material sufficient to remove one or more vaporized compounds from the heated vaporized components. In one example, the filtration segment 109 is made of a monoacetate material such as cellulose acetate. The filtration segment 109 provides cooling and reduction of user irritation from heated vaporized components without reducing the amount of heated vaporized components to an unsatisfactory level for the user.

The breakable capsule 5 is located in the filtration segment 109. It can be located substantially in the center of the filtration segment 109, both in diameter and in length. In other cases, it can be displaced in one or more directions.

The density of the cellulose acetate tow material for the filtration segment 109 affects the pressure drop across the filtration segment 109, which in turn affects the draw resistance for the item 101. Thus, the choice of material for the filtration segment 109 is important for controlling the draw resistance for the item 101. In addition, the filtering segment performs the filtering function in the item 101.

In one example, the filtration segment 109 is made of 8Y15 grade filter tow material that provides a filtering effect for the heated vaporized material while reducing the size of the condensed aerosol particles that are obtained from the heated vaporized material.

The presence of the filtration segment 109 provides an insulating effect by providing additional cooling to the heated vaporized components that exit the cooling segment 107. Additionally, the cooling effect reduces the contact temperature for the user's lips on the surface of the filtration segment 109.

In one example, the length of the filtration segment 109 is 6 to 10 mm, preferably 8 mm.

The mouthpiece segment 111 is an annular tube defining, inside the mouthpiece segment 111, an air gap located around it. The air gap forms a chamber for the flow of heated vaporized components that flow from the filtration segment 109. The mouthpiece segment 111 is hollow and forms an aerosol storage chamber. However, it is rigid enough to withstand the axial compressive forces and bending moments that can occur during manufacture and insertion into the device 51. In one example, the mouth segment 111 has a wall thickness of about 0.29 mm. The length of the mouthpiece segment 111 may be 6 to 10 mm, preferably 8 mm.

The mouthpiece segment 111 can be made from a spirally rolled paper tube to form a hollow inner chamber while maintaining an acceptable mechanical rigidity. Spirally wound paper tubes are capable of meeting stringent dimensional accuracy requirements for tube length, outer diameter, roundness and straightness for high speed fabrication processes.

The mouthpiece segment 111 has the function of preventing direct contact with the user of any liquid condensate that accumulates upon exiting the filtration segment 109.

It is clear that the mouth segment 111 and the cooling segment 107 can be made of one tube, and the filtration segment 109 is located in this tube, separating the mouth segment 111 from the cooling segment 107.

FIG. 5 and 6 show another exemplary embodiment of the article 301. The reference numbers shown in FIG. 5 and 6 are equivalent to the reference numbers shown in FIG. 3 and 4 and increased by 200.

In the example shown in FIG. 5 and 6 of the article 301, there is a ventilation region 317 allowing outside air to flow into the inside of the article. In one example, one or more openings 317 are formed in the ventilation region 317 in the outer layer of the article 301. Ventilation openings may be located in the cooling segment 307 to help cool the article 301. In one example, the ventilation region 317 comprises one or more rows of openings, and preferably each row of holes is located circumferentially around the article 301 in a cross section substantially perpendicular to the longitudinal axis of the article 301.

In one example, there may be one to four rows of holes to provide ventilation to the article 301. Each row of ventilation holes may contain from 12 to 36 holes 317. The diameter of the holes 317 may be, for example, from 100 to 500 microns. In one example, the axial spacing between the rows of holes 317 is 0.2 to 0.75 mm, preferably 0.5 mm.

In one example, the ventilation holes 317 are the same dimensions. In another example, ventilation openings 317 are of different sizes. The ventilation holes can be made using any suitable technology, such as laser technology, mechanically drilling the cooling segment 307, or pre-drilling the cooling segment 307 prior to making the article 301. The ventilation holes 317 are positioned to effectively cool the article 301.

In one example, the rows of ventilation holes 317 are located at least 11 mm from the proximal end 313 of the article, preferably 17 to 20 mm from the proximal end 313 of the article 301. The arrangement of the ventilation holes 317 is selected so that the user does not block the holes 317 when using product 301.

Arranging the rows of ventilation holes at a distance of 17 to 20 mm from the proximal end 313 of the article 301 allows them to be located outside the device 51 when the article 301 is fully inserted into the device 51, as shown in FIG. 8 and 9. Due to the location of ventilation openings on the outside of the device, outside unheated air can enter the article 301 through these openings, helping to cool the article 301.

The length of the cooling segment 307 is chosen such that when the article 301 is fully inserted into the device 51, the cooling segment 307 will only be partially inserted into the device 51. The length of the cooling segment 307 provides both a physical gap between the heating device of the device 51 and the heat sensitive filter device 309 and the possibility of positioning the openings 317 outside the device 51 when the article 301 is fully inserted into the device 51. As shown in FIG. 8 and 9, most of the cooling segment 307 is located in the device 51, but there is a portion of the cooling segment 307 that exits the device 51. It is in this region of the cooling segment 307 that exits the device 51 that the ventilation holes 317 are located.

FIG. 7-9 show in more detail a device 51 configured to heat an aerosol-forming material to vaporize at least one component of the material to produce an inhalation aerosol for a user. The device 51 is a heating device in which compounds are released by heating the aerosol-forming material without burning it.

The first end 53 of the device 51 is sometimes called the mouthpiece or proximal end 53, and the second end 55 is sometimes called the distal end 55 of the device 51. The device 51 includes an on / off button 57 so that the device 51 can be turned on and off as desired by the user.

The device 51 includes a housing 59 for positioning and protecting various internal components of the device 51. In the example shown, the housing 59 includes a one-piece housing 11 that surrounds the side surface of the device 51 and is covered by an upper panel 17 defining the "top" of the device 51 and a lower panel 19 defining The bottom of the device 51. In another example, the housing includes a front panel, a rear panel, and a pair of opposing side panels in addition to the top and bottom panels 17 and 19.

The top and / or bottom panels may be removably attached to the one-piece housing 11 to allow easy access to the interior of the device 51, or they may be permanently attached to the one-piece housing 11, for example, to keep the user from accessing the interior of the device 51. In one In an example, panels 17 and 19 are made of a plastic material comprising, for example, injection-molded glass-filled nylon, and the one-piece casing 11 is made of aluminum, although other materials and manufacturing processes could be used.

The upper panel 17 of the device 51 at the mouthpiece end 53 contains an opening 20 through which the article 101, 301 containing the aerosol-forming material can be inserted into the device 51 and removed from this device.

A heating device 23, a control circuit 25 and a power source 27 are located or attached to the housing 59. In this example, the heating device 23, the control circuit 25, and the power supply 27 are laterally adjacent (i.e., adjacent to each other when viewed from the end side), with the control circuit 25 substantially positioned between the heating device 23 and the power supply. 27 electricity, although other locations are possible.

The control circuit 25 may comprise a controller, such as a microprocessor, configured to control heating of the aerosol-forming material in the article 101, 301, which will be further described below.

The power source 27 may be, for example, a battery, which may be either a rechargeable battery or a non-rechargeable battery. Examples of suitable batteries are, for example, a lithium-ion battery, a nickel battery (such as a nickel-cadmium battery), an alkaline battery, and / or the like. The battery 27 is electrically connected to the heating device 23 for supplying electrical energy as needed and under the control of the control circuit 25 to heat the aerosol-forming material in the article (to vaporize the aerosol-forming material without burning this material).

An advantage of positioning the power source 27 laterally adjacent to the heater 23 is that a physically large power source 25 can be used without the need to make the device 51 excessively long. It is clear that the physically large power source 25 has a large capacity (i.e., the total electrical power that can be supplied, often measured in ampere hours or the like), hence the battery life in the device 51 may be longer.

In one example, the heating device 23 is in the form of a hollow substantially cylindrical tube having a hollow inner heating chamber 29 into which an article 101, 301 containing an aerosol-forming material is inserted for heating in use. Various designs of the heating device 23 are possible. For example, the heating device 23 can comprise a single heating element, or it can be constructed as a plurality of heating elements aligned along the longitudinal axis of the heating device 23. A single or each heating element can be annular or tubular, or at least partially annular. or partially tubular around the circumference. In one example, one or each heating element may be thin film. In another example, one or each heating element can be made of ceramic material. Examples of suitable ceramic materials are alumina and aluminum nitride and silicon nitride ceramics, which can be multilayer and can be sintered. Other heating devices are possible, including, for example, induction heating, infrared heating elements that are heated by emitting infrared radiation, or resistance heating elements, for example in the form of a resistive electric winding.

In one specific example, the heating device 23 is supported by a stainless steel support tube and includes a polyimide heating element. The heater 23 is sized so that substantially the entire volume of the aerosol-forming material 103, 303 of the article 101, 301 is located in the heater 23 when the article 101, 301 is inserted into the device 51.

A single or each heating element can be positioned such that selected zones of the aerosol generating material can be heated independently as desired, for example, one after the other (over time, as described above) or together (simultaneously).

The heating device 23 in this example is surrounded by a heat insulator 31 at least along part of its length. The insulator 31 helps to reduce the transfer of heat from the heating device 23 to the outside. This helps to reduce the power consumption of the heating device 23 since heat losses are reduced. The insulator 31 also helps to keep the outside of the device 51 cold while the heating device 23 is operating. In one example, the insulator 31 may be a double-walled sleeve between which there is a depressurization, i. E. the insulator 31 may be a "vacuum" tube, that is, a tube from which air is at least partially evacuated to minimize heat transfer by conduction and / or convection. Other designs of the insulator 31 are possible, including in addition to or instead of the double-walled sleeve it is possible to use thermal insulating materials, for example a suitable foam material.

The housing 59 may also include various internal support structures 37 to support all internal components as well as the heating device 23.

The device 51 also includes an annular bead 33 that extends around and protrudes from the opening 20 into the housing 59, and a substantially tubular chamber 35 that is located between the annular bead 33 and one end of the vacuum jacket 31. The chamber 35 further comprises a cooling structure 35f that , in this example, comprises a plurality of fins 35f spaced apart along the outer surface of the chamber 35, and each of which is located circumferentially around the outer surface of the chamber 35. Between the hollow chamber 35 and the article 101, 301 when inserted into the device 51, at least a portion of the length of the hollow chamber 35 has an air gap 36. The air gap 36 is located around the entire circumference of the article 101, 301 on at least a portion of the cooling segment 107.

The annular collar 33 contains a plurality of ribs 60, which are located circumferentially around the boundary of the hole 20 and protrude into the hole 20. The ribs 60 take up space in the hole 20, so that the open space of the hole 20 at the locations of the ribs 60 is less than the open space of the hole 20 in the places without ribs. 60. The ribs 60 are configured to engage the inserted article 101, 301 to be retained in the device 51. Open spaces (not shown) defined by adjacent pairs of ribs 60 and the article 101, 301 form ventilation paths around the outer portion of the article 101 , 301. These ventilation paths allow hot vapors exiting 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.

In use, the article 101, 301 is inserted into the insertion site 20 of the device 51 shown in FIG. 7-9. As shown in particular in FIG. 8, in one example, the volume of aerosol forming material 103, 301 that is disposed towards the distal end 115, 315 of the article 101, 301 is entirely within the heating device 23 of the device 51. The proximal end 113, 313 of the article 101, 301 protrudes from the device 51 and is a pre-assembled mouthpiece for the user.

In operation, the heating device 23 heats the article 101, 301 to vaporize at least one component of the aerosol-forming material from the bulk of the material 103, 303 to generate the aerosol.

The main flow path for heated vaporized components from the volume of aerosol-forming material 103, 303 runs axially through the article 101, 301, through the chamber located inside the cooling segment 107, 307, through the filtration segment 109, 309 and through the mouth segment 111, 313 to the user. In one example, the temperature of the heated vaporized components that are depleted from the bulk of the aerosol-forming material is 60 to 250 ° C, which may be above an acceptable temperature for inhalation by the user. As the heated vaporized component moves through the cooling segment 107, 307, it will cool and some of the vaporized components will condense on the inner surface of the cooling segment 107, 307.

In the examples of product 301 shown in FIGS. 5 and 6, cooling air is allowed to enter the cooling segment 307 through ventilation holes 317 that are provided in the cooling segment 307. This cooling air will mix with the heated vaporized components to further cool the heated vaporized components.

The ventilation improves the visibility of the heated vaporized components from the article 301 when the article is heated in the device 51. The heated vaporized components become visible due to their cooling as a result of the supersaturation process of the heated vaporized components. The heated vaporized components then undergo a droplet formation process, also known as active site formation, and ultimately the aerosol particle size of the heated vaporized components increases due to additional condensation of the heated vaporized components and due to the coalescence of newly formed droplets from the heated vaporized components.

In one embodiment of the invention, the ratio of the cooling air to the sum of the heated evaporated components and the cooling air, which is called the ventilation ratio, is at least 15%. A ventilation ratio of 15% allows heated vaporized components to become visible through the process described above. The visibility of the heated vaporized components allows the user to determine that vaporized components have been produced and adds a sensory experience to the smoking experience.

In another example, the ventilation ratio is between 50% and 85% to provide additional cooling for the heated vaporized components.
