The present invention relates to a delivery system and an aerosol generating material used in the delivery system.

Background of the invention

Certain tobacco industry products produce aerosols during use, and the aerosols are inhaled by users. Aerosols are produced by aerosolizable materials such as tobacco that are heated or burned during use. Some tobacco industry products may include flavoring agents.

Summary of the invention

According to the first aspect of the present disclosure, a delivery system is provided, which includes: an aerosol generating material including tobacco material and aerosolizable material, the aerosol generating material including inorganic material, binder, and aerosol forming agent Materials; and aerosol modifier release components containing aerosol modifiers.

Detailed description of the preferred embodiment

According to the first aspect of the disclosure, a delivery system is provided. As used herein, the term "delivery system" is intended to cover systems that deliver substances to users, and includes: Fuel aerosol supply system, such as cigarettes, cigarillos, cigars and tobacco used in pipes or used in roll-your-own cigarettes or used in make-your-own cigarettes (whether based on tobacco or tobacco) Derivatives, expanded tobacco, reconstituted tobacco, tobacco substitutes or other smokable materials); Non-aerosol supply systems (such as e-cigarettes, tobacco heating products, and mixing systems) that use a combination of aerosol-generating materials to release compounds from aerosol-generating materials to generate aerosols without burning aerosol-generating materials; as well as A combustible aerosol supply system, which contains an aerosol generating material and is configured to be used in one of these non-aerosol supply systems.

According to the present disclosure, a "flammable" aerosol supply system is a system in which the aerosol-generating material of the aerosol supply system (or its components) is burned or burned to facilitate delivery to users.

According to the present disclosure, a "non-flammable" aerosol supply system is a system in which the aerosol generating material, which is a component of the aerosol supply system (or its components), is not burned or burned to facilitate delivery to users.

In some embodiments, the delivery system is a combustible aerosol supply system, such as a system selected from the group consisting of cigarettes, cigarillos, and cigars.

In some embodiments, the present disclosure relates to a component used in a combustible aerosol supply system or a non-aerosol supply system, such as filters, filter rods, filter sections, tobacco rods, tobacco plugs (spill), such as Aerosol modifier release components for capsules, threads or beads, or paper such as cigarette holder forming paper, tipping paper or cigarette paper.

In some of the described embodiments, the delivery system is a non-aerosol supply system, such as an electric non-aerosol supply system. The non-aerosol supply system can be an electronic cigarette, also known as an electronic atomization device (vaping device) or an electronic nicotine delivery system (END), but it should be pointed out that the presence of nicotine in the aerosol generating material is not required.

The non-aerosol supply system can be a tobacco heating system, also known as a heat-not-burn system.

The non-aerosol supply system can be a hybrid system that uses a combination of aerosol-generating materials to generate aerosols, in which one or more aerosol-generating materials can be heated. Each of the aerosol-generating materials may, for example, be in solid, liquid or gel form and may or may not be nicotine-free. The mixing system may include liquid or gel aerosol generating materials and solid aerosol generating materials. The solid aerosol generating material may comprise, for example, tobacco or non-tobacco products.

Generally, the non-aerosol supply system may include a non-aerosol supply device and consumables used with the non-aerosol supply system. However, it is envisaged that the combustible aerosol supply system itself can form a non-aerosol supply system, and the combustible aerosol supply system itself includes components for powering the aerosol generating assembly.

The non-aerosol supply device may include a power source and a controller. The power source may be an electric power source or an exothermic power source. The exothermic power source may include a carbon matrix that can be energized to distribute power in the form of heat to an aerosolizable material or heat transfer material close to the exothermic power source. A power source such as an exothermic power source may be provided in the combustible aerosol supply system to form a non-aerosol supply system.

The aerosol generating component may be a heater capable of interacting with the aerosol generating material to release one or more volatiles from the aerosol generating material to form an aerosol. The aerosol generating component may be capable of generating aerosol from the aerosol generating material without heating. For example, the aerosol generating component may be capable of generating an aerosol from the aerosol generating material without applying heat to it, for example, via one or more of vibration, mechanical, pressure, or electrostatic means.

Consumables are products containing or composed of aerosol-generating materials, some or all of which are intended to be consumed by users during use. The consumable may include one or more other components, such as aerosol generating material storage area, aerosol generating material transfer component, aerosol generating area, housing, packaging, mouthpiece, filter, and/or aerosol modifier.

The consumable may also include an aerosol generator, such as a heater, which emits heat to cause the aerosol generating material to generate an aerosol in use. The heater may include, for example, a combustible material or a heat receiver, and the combustible material is a material that can be heated by conducting electricity.

The terms "upstream" and "downstream" as used herein are relative terms defined with respect to the direction of the mainstream aerosol pumped through the delivery system in use. Although the components or parts of the delivery system are referred to herein as "mouthpieces", the components or parts of the aerosol supply system may alternatively be parts or components downstream of the aerosol generating material, and do not need to be configured to at least partially Place the ground in the mouth of the user.

The delivery system contains aerosol generating materials. An aerosol generating material is a material capable of generating an aerosol when heated, irradiated or energized in any other manner, for example. The aerosol generating material is included in the aerosol generating area of the delivery system.

The aerosol generating material includes tobacco material. As used herein, the term "tobacco material" refers to material derived from plants of Nicotiana species. The selection of plants of Nicotiana species is not restricted, and the type of one or more tobaccos used can vary.

The term "tobacco material" may include one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes. The tobacco material may include one or more of the following: ground tobacco, tobacco fibers, tobacco shreds, extruded tobacco, tobacco stems, tobacco chips, reconstituted tobacco, and/or tobacco extracts.

In some embodiments, the tobacco material is selected from flue-cured tobacco or Virginia tobacco, Burley tobacco, sun-cured tobacco, Maryland tobacco, and deep-cured tobacco. Dark-fired tobacco, dark air cured tobacco, light air cured tobacco, lndian air cured tobacco, Red Russian tobacco and Rustica Tobacco, and mixtures thereof, and various other rare or special tobaccos such as green tobacco or dried tobacco. Tobacco materials produced by any other types of tobacco treatments (such as fermented tobacco or genetic modification or hybrid breeding techniques) that can adjust the taste of tobacco are also within the scope of this disclosure. For example, it is envisaged that tobacco plants can be genetically engineered or cross-breeded to increase or decrease the production of components, characteristics, or attributes.

In some embodiments, the tobacco material is sun-dried tobacco selected from the group consisting of Indian Kurnool tobacco or Oriental tobacco, which includes Izmir tobacco, Basma Tobacco, Samsun tobacco, Katerini tobacco, Prelip tobacco, Komotini tobacco, Xanthi tobacco and Yambol )tobacco. In some embodiments, the tobacco material is dark air-cured tobacco selected from the group consisting of Passanda tobacco, Cubano tobacco, Jatin tobacco, and Besuki tobacco. In some embodiments, the tobacco material is light-colored air-dried tobacco selected from the group consisting of North Wisconsin tobacco and Galpao tobacco.

In some embodiments, the tobacco material is a dried or non-dried mixture of cured tobacco, burley tobacco, and oriental tobacco.

In some embodiments, the tobacco material is selected from Brazilian tobacco including Mata Fina tobacco and Bahia tobacco. In some embodiments, the tobacco material is selected from criollo tobacco, piloto Cubano tobacco, Olor tobacco, Green River tobacco, Isabella DAC (Isabela DAC) tobacco, White Pata tobacco, Eluru tobacco, Jatim tobacco, Madura tobacco, Kasturi tobacco, Connecticut seed ( Connecticut Seed tobacco, Broad Leaf tobacco, Connecticut tobacco, Pennsylvania tobacco, Italian dry air cured tobacco, Paraguayan dry air cured tobacco and single One Sucker tobacco.

For the preparation of smoke-burning/electronic atomization or smokeless tobacco products, plants of Nicotiana species can undergo a drying process. Certain types of tobacco can undergo alternative types of drying processes, such as roasting or drying. Preferably, but not necessarily, the dried and harvested tobacco is aged.

Tobacco can be harvested at different growth stages, for example when the plant has reached a certain degree of maturity and the lower leaves are ready for harvest while the upper leaves are still developing.

In some embodiments, at least a portion of a plant of Nicotiana species (e.g., at least a portion of tobacco material) is used in an immature form. That is, in some embodiments, the plant or at least a portion of the plant is harvested before reaching a stage that is generally regarded as mature or mature.

In some embodiments, at least a portion of a plant of Nicotiana species (e.g., at least a portion of tobacco material) is employed in a mature form. That is, in some embodiments, the plant or at least a part of the plant is harvested when the plant (or plant part) reaches a point that is traditionally regarded as overripe, overripe, or mature. This can be done by using farmers’ knowledge To achieve the tobacco harvesting technology. Both oriental tobacco and burley tobacco plants can be harvested. In addition, Virginia tobacco can be harvested or picked according to the position of its stem.

Nicotiana species can be selected according to the content of various compounds present in the plant. For example, plants can be selected based on their plants producing relatively high amounts of one or more of the compounds desired to be isolated (ie, volatile compounds of interest). In some embodiments, plants of Nicotiana species are specifically cultivated because they are rich in foliar compounds. Tobacco plants can be grown in greenhouses, growing rooms, or outdoors in the wild, or grown by hydroponics.

Parts/portions of plants of Nicotiana species can be used in the methods defined herein. In some embodiments, the entire plant or substantially the entire plant is harvested and used as is. As used herein, the term "substantially the entire plant" means that at least 90% of the plant is harvested, such as at least 95% of the plant, such as at least 99% of the plant. Alternatively, in some embodiments, various parts or fragments of the plant are harvested or separated for further use after harvesting. In some embodiments, the tobacco material is selected from plant leaves, stems, stems, and various combinations of these parts. The tobacco material of the present disclosure may therefore comprise the whole plant or any part of the plant of Nicotiana species.

In order to achieve the desired flavor profile, the aerosol generating material used in the combustible aerosol supply system (such as the smoke-burning combustible aerosol supply system) usually includes tobacco materials obtained from different parts of tobacco plants, and tobacco materials obtained from different plants. And blends of tobacco materials that have undergone post-harvest processing.

The tobacco material may be tobacco materials of different species and/or blends of tobacco materials that have been processed according to a tobacco processing process. The blend of tobacco materials can be adjusted to change the functional properties of the aerosol produced during the use of the combustible aerosol supply system. For example, the relative amounts of different types of tobacco materials in the composition can be adjusted to change the functional properties of the composition.

The aerosol-generating material may include tobacco material in an amount of about 20% to about 90% by weight of the aerosol-generating material. In some embodiments, the aerosol-generating material is included in an amount of about 30% to about 85% by weight, about 35% to about 80% by weight, about 40% to about 75% by weight, or about 45% by weight of the aerosol-generating material. To about 70% by weight of tobacco material. In some embodiments, the aerosol-generating material contains tobacco material in an amount of about 50% to about 70% by weight of the aerosol-generating material. For example, the aerosol-generating material may be contained in an amount of about 50% by weight, 51% by weight, 52% by weight, 53% by weight, 54% by weight, 55% by weight, 56% by weight, 57% by weight, 58% by weight of the aerosol-generating material. %, 59% by weight, 60% by weight, 61% by weight, 62% by weight, 63% by weight, 64% by weight, 65% by weight, 66% by weight, 67% by weight, 68% by weight, 69% by weight, or about 70% by weight The tobacco material.

Unless specifically indicated to the contrary, when the amounts given herein are given in% by weight, for the avoidance of doubt, this means on a dry weight basis. Therefore, for the purpose of determining the weight %, any water that may be present in the tobacco material or any of its components is completely ignored. The moisture content of the tobacco materials described herein can vary and can be, for example, 2% to 25% by weight. The moisture content of the tobacco materials described herein can vary depending on, for example, the temperature, pressure, and humidity conditions that maintain the composition. The water content can be determined by Karl-Fisher analysis known to those skilled in the art.

As mentioned, tobacco plants include stems and tobacco leaves. During growth, the tobacco plant produces many compounds, including carbohydrate species (such as sugar and starch) and nicotine. Sugars are also produced during the drying of some types of tobacco plants.

In some embodiments, the tobacco material comprises tobacco leaves. The tobacco material may consist of tobacco leaves or it may comprise tobacco material obtained from other parts of the tobacco plant such as tobacco stems. In some embodiments, the tobacco material is a blend comprising tobacco leaves and tobacco stems.

Tobacco leaves may be in the form of whole leaves. In some embodiments, the tobacco material comprises dried whole tobacco leaves. In some embodiments, the tobacco material substantially comprises dried whole tobacco leaves. In some embodiments, the tobacco material consists essentially of dried whole tobacco leaves.

The ratio of sugar to nicotine varies throughout the tobacco plant. As used herein, the term "sugar(s)" is intended to cover total sugars, including reducing sugars (such as glucose and fructose) and non-reducing sugars (such as starch).

The ratio of sugar to nicotine in the leaves generally decreases from the leaves in the lower area of the plant to the leaves in the upper area of the plant. Therefore, the lower leaves of the tobacco plant (e.g., the lower half of the plant) contain a relatively higher ratio of sugar to nicotine than the leaves in the upper region (e.g., the first third) of the tobacco plant. The youngest tobacco leaves are found in the upper area of the tobacco plant, while the oldest tobacco leaves are found in the lower area of the tobacco plant. Generally, the leaves in the lower half of the tobacco plant contain less sugar than the leaves in the upper half of the tobacco plant. This is because the sugar in the lower half of the plant is transported to the leaves in the upper half of the plant to assist Growth and flowering.

When the tobacco material is aerosolized in the delivery system, the ratio of sugar to nicotine and the total sugar content of the tobacco material have an impact on the functional properties of the tobacco material. For example, during the processing of tobacco materials, sugars can be converted into other compounds that exhibit desired functional properties.

Although the tobacco material is required to contain sugar, the relatively high sugar content during smoking: nicotine content can cause "astringent" taste and/or irritation, which may be undesirable. Therefore, the lower stems and leaves and the middle stems and leaves that contain a relatively high ratio of sugar to nicotine conventionally constitute a secondary component (less than 5 wt%) of the conventional aerosol generating material used in the combustible aerosol supply system.

Tobacco leaf may contain sugar and nicotine in a certain weight ratio range. The tobacco leaf contains tobacco leaf containing sugar and nicotine in a weight ratio between about 8:1 and about 20:1. It may also contain tobacco leaves containing sugar and nicotine whose weight ratio is outside this range.

In some embodiments, the tobacco leaf contains a weight ratio (sugar: nicotine) of at least about 8:1, 9:1, 10:1, 11:1, 12:1, 13:1, 14:1, 15:1, 16:1, 17:1, 18:1 or 19:1 sugar and nicotine. In some embodiments, the tobacco leaf contains a weight ratio (sugar: nicotine) of no more than about 20:1, 19:1, 18:1, 17:1, 16:1, 15:1, 14:1, 13:1, 12:1, 11:1, 10:1 or 9:1 sugar and nicotine. The tobacco material may comprise a weight ratio of about 8:1, 9:1, 10:1, 11:1, 12:1, 13:1, 14:1, 15:1, 16:1, 17:1, 18: 1. 19:1 or 20:1 sugar and nicotine. In some embodiments, the weight ratio of sugar to nicotine in tobacco leaves is between about 10:1 and about 15:1. In some embodiments, the weight ratio of sugar to nicotine in the tobacco leaf is about 9:1, 10:1, 11:1, or about 12:1.

In some embodiments, the tobacco material is contained in an amount of about 25% by weight, 26% by weight, 27% by weight, 28% by weight, 29% by weight, 30% by weight, 31% by weight, 32% by weight, 33% by weight of the tobacco material , 34% by weight, 35% by weight, 36% by weight, 37% by weight, 38% by weight, 39% by weight, 40% by weight, 41% by weight, 42% by weight, 43% by weight, 44% by weight or 45% by weight Tobacco leaf with sugar and nicotine weight ratio between about 8:1 and about 20:1.

The inventor of the present application has unexpectedly discovered that tobacco leaves containing lower stalks, that is, tobacco leaves containing sugar and nicotine in an amount greater than 5% by weight of the tobacco material, with a weight ratio between about 8:1 and about 20:1 The tobacco material can be combined with the aerosol forming agent material to provide an aerosol generating material with excellent functional characteristics when used in a combustible aerosol supply system. Not only that, since the tobacco material contains relatively high content of low-stem tobacco leaves, the resulting aerosol-generating material has a very desirable light color compared with the conventional aerosol-generating material.

In some embodiments, tobacco leaves containing sugar and nicotine in a weight ratio between about 8:1 and about 20:1 are lower stem tobacco leaves.

The tobacco leaves can be post-harvested before being incorporated into the aerosol-generating material. For example, tobacco leaves can be dried (including roasting and air-drying), aging, fermenting, or moisture regain before being included in the aerosol-generating material.

In some embodiments, the cut width of the shredded tobacco material is about 0.8 to about 1.8 or about 0.9 to about 1.7 cuts/mm. In some embodiments, the cut width of the shredded tobacco material is between about 1.4 and about 1.6 cuts/mm, or about 1.45 cuts/mm, or about 37 cuts/inch.

The tobacco material may comprise an aerosol former material. The aerosol former material contains one or more components capable of forming an aerosol. The aerosol forming agent material may comprise one or more of the following or consist of one or more of the following: glycerol, glycerin, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3- Butylene glycol, erythritol, meso-erythritol, ethyl vanillate, ethyl laurate, diethyl suberate, triethyl citrate, glyceryl triacetate, glyceryl diacetate mixture, benzene Benzyl formate, benzyl phenyl acetate, tributyrin, lauryl acetate, lauric acid, myristic acid, sorbitol and propylene carbonate.

In some embodiments, DIET is present in an amount of about 5% to about 30%, about 10% to about 20%, or about 10% to about 15%.

Advantageously, when the delivery system is a combustible aerosol supply system, the DIET material can improve the combustion characteristics of the combustible aerosol supply system. For example, it can increase the burning rate or reduce the chance of burning being extinguished. In addition, DIET usually has a higher filling value than tobacco leaves. This means that for a given volume, the weight of the aerosol-generating material containing DIET can be less than the weight of the aerosol-generating material without DIET. Including DIET in the aerosol-generating material can therefore reduce the total weight of the aerosol-generating material and therefore reduce transportation costs.

In some embodiments, the tobacco stem is present in an amount between about 5% and about 50% by weight of the tobacco material.

Advantageously, when the delivery system is a combustible aerosol supply system, the stem can improve the combustion characteristics of the combustible aerosol supply system. For example, it can increase the burning rate or reduce the chance of burning being extinguished. It can also reduce the costs associated with manufacturing the delivery system, because the stem can be a cheaper material than the other components of the aerosol generating material.

For example, the aerosolizable material may be included in an amount of about 1% by weight, 5% by weight, 10% by weight, 20% by weight, 30% by weight, 40% by weight, 50% by weight to about 90% by weight of the aerosolizable material. , About 60% to about 85% by weight or about 75% to about 80% by weight of inorganic materials.

The aerosolizable material includes one or more aerosol former materials, as previously described. The aerosolizable material may be included in an amount of about 1% to about 30% by weight, 5% to about 30% by weight of the aerosolizable material, or about 5% to about 20% by weight of the aerosolizable material Aerosol former material. In some embodiments, the aerosolizable material is 9% to about 16% by weight of the aerosolizable material, and about 10% to about 15% by weight or about 11% to about 14% by weight of the aerosolizable material. It is present in an amount of weight% or about 12 weight% to about 13 weight %.

In some embodiments, the aerosolizable material includes the aerosol forming agent material in an amount of about 10 wt% to about 20 wt% based on the total weight of the aerosolizable material, based on the total weight of the aerosolizable material The binder in an amount of about 1 wt% to about 10 wt% and an inorganic material in an amount of about 75 wt% to about 85% by weight based on the total weight of the aerosolizable material. The aerosol former material is preferably glycerin or propylene glycol, but other aerosol former materials (including any of the materials described herein) can also be used.

The total content of the aerosol forming agent material in the aerosol generating material may be between about 1% by weight and about 20% by weight of the aerosol generating material.

The aerosolizable material can include any of the flavors described herein.

In some embodiments, the aerosolizable material comprises tobacco extract. Tobacco extracts can be prepared by any method that those skilled in the art will know. Including tobacco extract in the aerosolizable material can further enhance the flavor of the aerosol-generating material.

Optionally, the aerosol-generating material may include an aerosolizable material and a tobacco material, and the tobacco material contains at least 5% by weight of the tobacco material in a sugar ratio between about 8:1 and about 20:1. And nicotine tobacco.

In some embodiments, the aerosolizable material does not contain any colorants. Alternatively, the aerosolizable material may contain a colorant. Colorants can change the visual appearance of aerosolizable materials. The presence of the colorant in the aerosolizable material can enhance the visual appearance of the aerosol generating material containing the aerosolizable material. For example, the aerosolizable material can be color-matched to the tobacco material so that when the two materials are combined, the aerosolizable material is visually blended in the tobacco material. The color of the aerosolizable material can be white, green, blue, brown or black. In a preferred embodiment, the color of the aerosolizable material is white.

In some embodiments, the color of the aerosol generating material can be adjusted to achieve any desired color. For example, a material (such as a coloring agent) that is formulated to change the appearance of the aerosol-generating material can be applied to some or all of the aerosol-generating material. In some embodiments, materials that are formulated to change the appearance of the aerosol-generating material (for example, before blending these materials) are separately applied to the tobacco material and/or the aerosolizable material. The material formulated to change the appearance of the aerosol-generating material can be applied to the aerosol-generating material after or during the blending of the aerosolizable material and the tobacco material. The material formulated to change the appearance of the aerosol generating material can be applied by spraying, for example.

The aerosolizable material can be formed into a sheet of material, and then cut or shredded into separate individual pieces or parts of the material.

The cutting width of the crushed aerosolizable material tobacco material can be about 0.5 cuts/mm to about 2.5 cuts/mm. In some embodiments, the cut width of the crushed aerosolizable material is about 0.8 to about 1.8 or about 0.9 to about 1.7 cuts/mm. In some embodiments, the cutting width of the crushed aerosolizable material is between about 1.4 and about 1.6 cuts/mm, or about 1.45 cuts/mm, or about 37 cuts/inch.

The crushed aerosolized material may have a cutting width of about 0.2 to about 1 cut/mm, about 0.3 to about 0.9 cuts/mm, about 0.4 to about 0.8 cuts/mm, or about 0.5 to about 0.7 cuts/mm .

The aerosolizable material can be manufactured by combining the aerosol forming agent materials, binders, inorganic materials and optional flavors with a solvent such as water; pouring the slurry on a heated band molding machine (heated band caster) to produce wet flakes; and the wet flakes are dried to provide an aerosolizable material. The aerosolizable material can be further processed. For example, the aerosolizable material can be shredded.

The aerosolizable material may have a moisture content between about 1% and about 10% after drying. In a preferred embodiment, the moisture content of the aerosolizable material is between about 2% and about 5%.

The aerosolizable material may not exhibit undesirable functional properties when heated or burned. Therefore, when the aerosol-generating material is heated, the aerosol generated by the aerosol-generating material exhibits a smooth and neutral flavor profile and does not release a strong or unpleasant flavor. Without wishing to be bound by theory, it is assumed that this is attributable to aerosolizable materials that have a diluting effect on the smoke stream.

In some embodiments, according to the method as previously described, the aerosol-generating material includes one or more flavors applied to the surface of the aerosol-generating material or included in the aerosolizable material. The inventors of the present invention have unexpectedly discovered that when the aerosol-generating material contains a flavor, the user can easily perceive the flavor. Therefore, it may be necessary to add a relatively small amount of flavoring agent to the composition to achieve the desired flavor profile. For example, one or more flavoring agents may be added to the aerosol generating material and/or the aerosolizable material in an amount of less than about 2000 ppm (for example, about 100 ppm, 500 ppm, 1000 ppm, 1500 ppm). In some embodiments, one or more flavors are added in an amount between about 2000 ppm and about 12000 ppm, such as about 2000 ppm, 3000 ppm, 4000 ppm, 5000 ppm, 6000 ppm, 7000 ppm, 8000 ppm, 9000 ppm , 10000 or 11000 ppm.

Instead of or in addition to being applied to the surface of the aerosol-generating material, flavoring agents may be incorporated into the aerosolizable material. For example, the aerosolizable material may contain embedded flavors. Flavors can be added to the aerosolizable material during the manufacture of the aerosolizable material. Advantageously, when the flavoring agent is included in the aerosolizable material, it can be released from the aerosolizable material more slowly than the flavoring agent included on the surface of the aerosol generating material. This can extend the shelf life of the aerosol generating material and the time period during which the flavor is released during the smoking of the article.

The flavoring agent may be added to the aerosolizable material in an amount between about 0.01% by weight and about 0.1% by weight of the aerosolizable material.

In addition, due to the relatively neutral functional properties of the described aerosol-generating materials, flavors that are not traditionally used in, for example, cigarettes, such as flavors that exhibit a light mouthfeel and/or aroma, can be used herein.

As used herein, the terms "flavoring agent" and "flavoring agent" refer to materials that can be used to produce the desired taste or aroma in products for adult consumers under the circumstances permitted by local regulations. One or more flavoring agents can be used as the aerosol modifiers described herein. It may include extracts (e.g. licorice, matcha, grapefruit, cappuccino, cranberry, star fruit, hydrangea, Japanese white magnolia leaf, chamomile, fenugreek, clove, menthol, Japanese mint, anise seed , Cinnamon, herb, holly, cherry, berry, peach, apple, doolin whisky, bourbon, scotch, spearmint, peppermint, lavender, cardamom, celery, quinoa peel, nutmeg, sandalwood, bergamot , Geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, Chinese cinnamon, coriander, brandy, jasmine, perfume tree, sage, cumin, sweet pepper, ginger, star anise, coriander, coffee or from Peppermint oil of any species of the genus Peppermint), flavor enhancers, bitter receptor site blockers, sensory receptor site activators or stimulants, sugar and/or sugar substitutes (e.g. sucralose, potassium acesulfame Spartame, saccharin, Cyclamate, lactose, sucrose, glucose, fructose, sorbitol or mannitol) and other additives such as charcoal, chlorophyll, minerals, plant products or breath fresheners. It can be imitations, synthetic or natural ingredients or blends thereof. It can be in any suitable form, such as oil, liquid or powder.

In some embodiments, the flavoring agent includes menthol, spearmint, and/or peppermint. In some embodiments, the flavor includes the flavor components of courgette, blueberry, citrus fruit and/or cranberry. In a specific embodiment, the flavoring agent is cappuccino. In some embodiments, the flavoring agent comprises eugenol. In some embodiments, the flavoring agent comprises flavor components extracted from tobacco. In some embodiments, the flavoring agent includes flavor components extracted from hemp.

In some embodiments, the flavoring agent may include a sensory agent, which is intended to achieve a certain somatosensory, which is usually determined by the fifth cranial nerve (trigeminal nerve) in addition to or in place of the aromatic odor or taste nerve. Stimulates chemical induction and perception, and these flavoring agents may include agents that provide fever, cooling, tingling, and numbing effects. A suitable thermal agent may be but not limited to vanillyl ether, and a suitable cooling agent may be but not limited to eucalyptol WS-3.

When the aerosol-generating material includes the aerosolizable material and flavor or sensation as described herein, compared with the aerosol-generating material that does not include the aerosolizable material, the aerosol-generating material can enhance the user’s The perception of flavors or sensates. Without wishing to be bound by theory, it is believed that the relatively neutral flavor characteristics of the aerosolizable material means that the aerosolizable material can act as a "flavor carrier" and enhance other flavors or sensations.

The aerosol supply system contains an aerosol modifier. Aerosol modifiers are substances usually located downstream of the aerosol generation area, which are formulated to adjust the aerosol generation by changing the taste, flavor, acidity or another characteristic of the aerosol when the aerosol generating material is heated. Aerosol produced by the material.

The aerosol modifier can be, for example, an additive or a sorbent. The aerosol modifier may, for example, include one or more of flavoring agents, coloring agents, water, and carbon adsorbents. The aerosol modifier may be solid, liquid or gel, for example. The aerosol modifier may be in the form of powder, thread or granule. The aerosol modifier may not contain filter materials.

The preferred aerosol modifiers are flavors and sensates as previously described.

As previously indicated, the aerosols produced by the aerosol-generating materials described herein exhibit relatively smooth and neutral functional properties. The inventors have discovered that the aerosol generating material does not tend to mask the aerosol modifiers present in the aerosol. This means that aerosols can serve as "carriers" for aerosol modifiers. Therefore, the functional properties of the aerosol modifier can be easily perceived by the user, and it may be necessary to add a lower amount of aerosol modifier to the aerosol-generating material to achieve the desired aerosol characteristics, and the aerosol-generating material The generated aerosol can be used to carry a variety of different aerosol modifiers.

The aerosol modifier is provided in or on the aerosol modifier release component, and the component is operable to selectively release the aerosol modifier. The aerosol modifier releasing component can be a capsule, thread or bead, or a package such as paper packaging, cigarette holder forming paper, tipping paper or cigarette paper. Aerosol modifiers are not part of the aerosol generating material. The aerosol generating material does not contain an aerosol modifier.

In some embodiments, the aerosol modifier release component is a package containing the aerosol modifier, especially tipping paper. Any of the tipping paper or paper/package described herein may contain aerosol modifiers, such as sensory materials.

In some embodiments, the sensory material may include one or more of pH adjusters, stabilizers, and/or antioxidants. These materials can help increase the storage life of the package and therefore increase the storage life of the combustible aerosol supply system.

The aerosol modifier can be encapsulated in the encapsulating material. For example, the sensate material can be provided in the form of microcapsules applied to tipping paper or other packaging. Encapsulated aerosol modifiers can provide various advantages. For example, the encapsulated aerosol modifier may include or consist of a flavoring agent having a desired mouthfeel or aroma. Encapsulation can enhance the durability of taste and/or aroma.

In particular, the encapsulated aerosol modifier can improve the durability of the aroma of the aerosol modifier by enhancing the flavor detected by the user. Therefore, even after the flavor is reduced (for example, when the flavor is no longer detectable by the user or less detectable by the consumer), the aroma can continue to be detected by the user, thereby enhancing the user’s experience. Experience.

The encapsulated aerosol modifier can also help mask other aromas that can be released by the components of the combustible aerosol supply system, so that it can be used in the non-aerosol supply system before or during the use of the non-aerosol supply system.

The encapsulated aerosol modifier can exhibit aroma indicating the flavor of the aerosol modifier. For example, the aroma can provide the user with a hint of the flavor of the aerosol modifier. This can help users quickly determine the flavor of the sensory material.

In some embodiments, the aerosol modifier release component is a capsule.

The capsule may have a core-shell structure. The core-shell structure comprises a shell that encapsulates a liquid agent such as an aerosol modifier as described herein. The shell of the capsule can be assembled to be ruptured by the user to release the aerosol modifier.

The delivery system may contain separate capsules, or it may contain more than one capsule.

The shell of the capsule may contain an encapsulating material or a barrier material that creates a shell around the core containing the aerosol modifier. The shell structure prevents the migration of the aerosol modifier during storage in the delivery system, but allows the aerosol modifier to be released during use.

The barrier material (also referred to herein as the encapsulating material) is fragile. The capsule is crushed by the user or otherwise ruptured or broken to release the encapsulated aerosol modifier. Usually, the capsule is broken just before the heating starts, but the user can choose when to release the aerosol modifier. The term "breakable capsule" refers to a capsule in which the shell can be broken by pressure to release the core; more specifically, when the user wishes to release the core of the capsule, the shell can be under pressure from the user's fingers rupture.

In some embodiments, the filter may include a capsule and a plurality of particles that are configured such that, in use, the particles cause the capsule to break after the user applies an external force to the wall of the tobacco industry product component. The particles can be made of a stronger (e.g., harder) material than the capsule shell. This helps to promote the breakage of the additive capsule after the application of external force. Stronger particles also help prevent the capsule from breaking during transportation. For example, a suitable configuration is described in WO 2019/207302.

In some cases, the barrier material is heat resistant. That is, in some cases, the barrier will not rupture, melt or otherwise fail at the temperature reached at the capsule site during the operation of the aerosol supply device. Illustratively, the capsule located in the mouthpiece can be exposed to a temperature in the range of, for example, 30°C to 100°C, and the barrier material can continue to maintain the liquid core up to at least about 50°C to 120°C.

In other cases, the capsule releases the core composition when heated, for example by melting the barrier material or rupturing the barrier material by expanding the capsule.

The capsule may be spherical and have a diameter of about 3 mm to about 3.5 mm. In other embodiments, other shapes and sizes of capsules can be used. For example, the capsule may have a diameter of less than 4 mm or less than 3.5 mm or less than 3.25 mm. In alternative embodiments, the capsule may have a diameter greater than about 3.25 mm (e.g., greater than 3.5 mm or greater than 4 mm).

The total weight of the capsule may be in the range of about 1 mg to about 100 mg, suitably about 5 mg to about 60 mg, about 8 mg to about 50 mg, about 10 mg to about 20 mg, or about 12 mg to about 18 mg .

In some cases, the gelling agent may comprise carrageenan and/or gellan gum; these gelling agents are particularly suitable for inclusion as a gelling agent because the pressure required to break the resulting capsule is particularly suitable .

The barrier material may contain one or more build-up agents, such as starch, modified starch (such as oxidized starch), and sugar alcohols such as maltitol.

The barrier material may contain a coloring agent, which makes it easier to position the capsule in the aerosol generating device during the manufacturing process of the aerosol generating device. The coloring agent is preferably selected from colorants and pigments.

Methods of preparing capsules include co-extrusion, optionally followed by centrifugation and solidification and/or drying. The content of WO 2007/010407 A2 is incorporated by reference in its entirety.

The delivery system may include filters. The filter can be placed in the mouthpiece of the delivery system to filter the aerosol generated by the aerosol-generating material during the use of the delivery system.

The filter may contain a body of material. The material body may include filamentous fiber bundles.

Exemplary Example Exemplary Example 1

Fig. 1 is a schematic diagram of a combustible aerosol supply system 1a, which is substantially cylindrical in shape. The delivery system includes a rod 2, which contains an aerosol-generating material and is packaged in a packaging material 3 (in this example, cigarette paper), by covering the filter tip 4 on the tipping material 5 and partially covering the packaging material 3 It is connected longitudinally to the filter 4 in order to connect the filter 4 to the rod 2. The filter contains an absorbent material 7 and is packaged in a cigarette holder forming paper 8.

There are a range of packaging materials that are suitable for packaging aerosol generating materials. The packaging material can have a variety of colors. In some embodiments, the color of the packaging material can be selected to match or coordinate with the aerosol generating material. The packaging material can also be translucent or transparent so that the user can identify the aerosol generating material in the consumable. For example, the aerosol-generating material or the components of the aerosol-generating material may have a unique appearance visible to the user through a transparent or translucent package.

As described herein, aerosol-generating materials may include tobacco materials and aerosolizable materials. In some embodiments, the distribution of the tobacco material and the aerosolizable material in the rod 2 is uniform. Alternatively, the distribution of the tobacco material and the aerosolizable material in the rod 2 is not uniform. The concentration of the aerosolizable material in the aerosol generating material varies along the length of the rod 2. For example, the closer to the mouthpiece, the higher the concentration of the aerosolizable material can be present. This can improve the smoothness of the aerosol produced by the consumable near the end of the smoking period. When the aerosolizable material contains flavors, the aerosol produced by the consumables near the end of the smoking period can have a particularly high concentration of flavor, so the sensory properties of the consumables are changed (for example, improved) at the end of the smoking period .

In this example, the axis area is an area with a radius of about 3 mm centered on the axis "a" of the conveying system 1a. In alternative embodiments, the radius of the shaft region may be 1 mm to 4 mm, or 1 mm to 3 mm, or about any of 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, or 3.5 mm.

The axis of the conveying system 1a around which the tobacco rod 2 and the filter 4 are aligned is indicated as "a" in FIG. 1. Exemplary Example 2

Fig. 2 is a schematic diagram of the combustible aerosol supply system 1b.

The reference numbers are based on the embodiment shown in FIG. 1 and remain unchanged as previously described.

The capsule 9 is provided in the filter 4. The capsule contains an aerosol modifier that adjusts the characteristics of the main smoke flow passing through the smoking article 2. The capsule can be manufactured using existing manufacturing processes and machinery and inserted into the filter 4. In this example, the capsule contains menthol flavoring agent, but the capsule may also contain other fluid or particulate additives.

The capsule 9 may be a breakable capsule, such as a capsule having a solid fragile shell surrounding a liquid payload. The capsule can be ruptured by the consumer to release the fluid additives into the absorbent filter material 7. The capsule 9 is completely embedded in the material body 7. In other words, the capsule 9 is completely surrounded by the material forming the material body 7.

In this example, a single capsule 9 is used. In alternative embodiments, the filter 4 may contain one or more capsules. In other examples, a plurality of breakable capsules may be arranged in the material body 7, such as two, three or more breakable capsules. The length of the material body 7 can be increased to accommodate the number of capsules required. In an example where multiple capsules are used, the individual capsules may be the same as each other, or may be different from each other in terms of size and/or capsule payload.

In other examples, a plurality of material bodies 7 may be provided, wherein each body contains one or more capsules. Exemplary Example 3

Fig. 3 is a schematic diagram of a combustible aerosol supply system 1c. The reference numbers remain unchanged according to the embodiments shown in FIGS. 1 and 2 as previously described.

The filter 4 includes a first section 7a made of an absorbent material and a second section 10 at the mouth end of the filter 4. The second section includes a filter material 11 formed in a tubular shape and has an extension through Pass through the channel 12 in the center of the filter material 11. The diameter of the hollow channel or hollow channel 12 extending through the center of the filter material 11 may be 1 mm to 6 mm, for example, the diameter may be 2 mm to 5 mm. In this example, the channel 12 extending through the center of the filter material 11 is a hollow hollow channel. In some embodiments, the channel extends through the axial region of the filter material of the second filter section 10. In this example, the axis area of the second filter section 10 is an area centered on the axis "a" of the smoking article 1 and having a radius of about 2.5 mm. In alternative embodiments, the radius of the shaft region may be 1 mm to 4 mm, or 1 mm to 3 mm, or about any of 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, or 3.5 mm. In this example, the tubular filter section is formed of cellulose acetate fiber bundles and is packaged in the second cigarette holder forming paper 13. The wall thickness of the tubular filter is about 1.5 mm. In alternative embodiments, the wall thickness may be 1 mm to 4 mm, or 1 mm to 3 mm, or about any of 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, or 3.5 mm. However, the specific size can be selected based on the density of the filter material forming the tube and the amount of plasticizer applied to the material to produce a tube with the required rigidity, porosity, or other characteristics. The tubular filter section 10 can be manufactured using existing manufacturing processes and machinery.

When the consumer breaks the capsule 9 before smoking the smoking product 1 or in the process of smoking the smoking product 1, the aerosol modifier (in the present case, menthol) contained therein is released at a higher concentration to In the shaft area of the first filter section 7a, due to the second filter section 10, an increased main smoke flow is guided through the shaft area. Therefore, the increased main smoke flow enhances the delivery of smoke adjustment additives to consumers, and compared with conventional tobacco products, the tobacco product 1c can therefore exhibit improved delivery of smoke adjustment additives to consumers.

The aerosolizable material is manufactured as follows. Combine water and sodium alginate (Protanal® RF6650, 8% by dry weight) and mix in a high shear mixer for 15 minutes. Chalk (79% by dry weight) and glycerin (13% by dry weight) were added to the mixture and mixed for 5 minutes. Stir the mixture in the tank until the slurry reaches a uniform consistency. Subsequently, a heated belt molding machine (pouring width 800 mm; 80 to 90° C., 20 minutes) was used to cast the slurry to produce a wet sheet with a thickness of about 0.5 mm. Subsequently, a shredder was used to shred the aerosolizable material at 37 cuts/inch (about 1.5 cuts/mm) to provide shredded aerosolizable material. Exemplary Example 5-Aerosol Generating Material

The aerosolizable material prepared as described above is blended with the tobacco material to produce an aerosol generating material comprising tobacco and aerosolizable material. The relative amounts of the aerosolizable material and the tobacco material in the aerosol generating material are shown in Table 1.

The tobacco contains about 50 wt% tobacco leaves based on the total weight of the composition. About 40 wt% of tobacco leaves are obtained from the lower half of the leaves of the tobacco plant and have a sugar to nicotine ratio of about 10:1. Based on the total weight of the composition, the aerosol generating material contains about 18 wt% tobacco stems.

The aerosol generating material of Exemplary Example 5 was used to manufacture three types of cigarettes including filters. Cigarettes containing aerosol-generating materials can be sold under the name "White Tobacco". One type of cigarette does not contain any additional flavoring agents. The other two cigarettes contain flavoring agents (menthol, 1 mg).

The combination is shown in Table 2. Table 2 cigarette Flavoring agent* 1 without 2 Yes (Cranberry) 3 Yes (Cappuccino) **Added to the sensory evaluation of aerosol-generating materials

The sensory characteristics of cigarettes 1 to 3 were evaluated by a group of professional smokers relative to a control cigarette (Kent Super Slim (1 mg menthol)) that did not contain the aerosolizable material as described herein.

This group of professional smokers concluded that when smoking, cigarettes 1 to 3 exhibited better aftertaste, better flavor perception, and better mouthfeel compared to control cigarettes.

Professional smokers reported that despite the same menthol flavoring content (1 mg), cigarettes 2 and 3 exhibited significantly improved cooling sensations compared to control cigarettes.
