As used herein, the term "delivery system" is intended to cover a system that delivers at least one substance to a user, and includes: Fuel aerosol supply system, such as cigarettes, cigarillos, cigars and pipe tobacco or cigarette tobacco or homemade cigarette tobacco (whether in tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, tobacco substitutes or other inhalable materials Mainly); Non-aerosol supply systems, which release compounds from aerosol-generating materials without burning aerosol-generating materials, such as electronic cigarettes, tobacco heating products, and hybrid systems that use aerosol-generating materials to generate aerosols; An aerosol-free delivery system that delivers at least one substance orally, nasally, transdermally or in another way to the user without forming an aerosol, including but not limited to lozenges, chewing gums, patches, including inhalable Powdered products and oral products, such as oral tobacco including snuff or moist snuff, in which at least one substance may or may not contain nicotine.

According to the present disclosure, a "flammable" aerosol supply system is an aerosol in which the constituent aerosol generating material of the aerosol supply system (or its components) is burned or ignited during use in order to deliver at least one substance to the user Supply system.

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 components used in the combustible aerosol supply system, such as filters, filter rods, filter segments, tobacco rods, empty tubes, aerosol modifier release components (such as capsules, threads, or beads). Pellets) or paper (such as forming paper, tipping paper or cigarette paper).

According to the present disclosure, a "non-flammable" aerosol supply system is an aerosol supply in which the constituent aerosol-generating material of the aerosol supply system (or its components) is not burned or ignited to facilitate the delivery of at least one substance to the user system.

In some embodiments, the delivery system is a non-aerosol supply system, such as a powered non-aerosol supply system.

In some embodiments, the non-aerosol supply system is an electronic cigarette, also known as an electronic cigarette smoking device or an electronic nicotine delivery system (END), but it should be noted that nicotine is not required to be present in the aerosol generating material.

In some embodiments, the non-aerosol supply system is an aerosol generating material heating system, also known as a thermal non-combustion system. An example of such a system is a tobacco heating system.

In some embodiments, the non-aerosol supply system is a hybrid system that uses a combination of aerosol-generating materials to generate aerosols, and one or more of the 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 contain nicotine. In some embodiments, the mixing system includes a liquid or gel aerosol generating material and a solid aerosol generating material. 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 device.

In some embodiments, the present disclosure relates to consumables that contain aerosol generating materials and are configured to be used with non-aerosol supply devices. Throughout this disclosure, these consumables are sometimes referred to as products.

In some embodiments, the non-aerosol supply system, such as its non-aerosol supply device, may include a power source and a controller. The power source may be, for example, an electric power source or an exothermic power source. In some embodiments, the exothermic power source includes a carbon matrix that can be energized to distribute power in the form of heat to the aerosol generating material or heat transfer material close to the exothermic power source.

In some embodiments, the non-aerosol supply system may include an area for receiving consumables, an aerosol generator, an aerosol generating area, a housing, a mouthpiece, a filter, and/or an aerosol modifier.

In some embodiments, the delivery system is an aerosol-free delivery system that delivers at least one substance to the user orally, nasally, transdermally, or in another manner without forming an aerosol, including but not limited to lozenges , Chewing gum, patches, products containing inhalable powder and oral products, such as oral tobacco including snuff or moist snuff.

Tobacco plants include stems and tobacco leaves. During growth, tobacco plants produce a variety of compounds, including carbohydrate species (such as sugar and starch) and nicotine. Sugar is also produced during the preparation of some tobacco plant varieties.

As used herein, the terms "sugar" and "sugars" are intended to encompass total sugars, including reducing sugars (such as glucose and fructose) and non-reducing sugars (such as starch).

In the whole tobacco plant, the ratio of sugar to nicotine is different. The ratio of sugar to nicotine in 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 leaves of the lower part of the tobacco plant (e.g., the lower half of the plant) contain a relatively higher ratio of sugar to nicotine than the leaves of the upper area of the tobacco plant (e.g., the top third). The youngest tobacco leaves are in the upper area of the tobacco plant, while the oldest tobacco leaves are in the lower area of the tobacco plant. Generally, the leaves of the lower half of the tobacco plant have lower sugar content than the leaves of the upper half of the tobacco plant, because the sugar in the lower half of the plant is transferred to the leaves of the upper half of the plant to help growth and flowering.

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

Although the tobacco material is expected to contain sugar, the relatively high sugar and nicotine content can result in "astringent" taste and/or irritation during smoking, which may be undesirable. Therefore, the conventional low-stem leaves and middle-stem leaves containing relatively high sugar to nicotine ratio constitute a minor component (less than 5% by weight) of the conventional tobacco composition used in the combustible aerosol supply system.

As used herein, the term "tobacco material" refers to material derived from Nicotiana plant plants. The selection of tobacco planting plants is not restricted, and the type of one or more tobaccos used may be different.

In some embodiments, the tobacco material is selected from flue-cured tobacco or Virginia, Burley, sun-cured, Maryland, dark-cured tobacco, dark-cured tobacco, and light-cured tobacco. , Indian air-cured tobacco, Red Russian and yellow flower tobacco and their mixtures, as well as various other rare or special tobaccos, which are untreated or prepared. Through any other types of tobacco treatments that can change the taste of tobacco, such as fermented tobacco or tobacco materials produced by genetic modification or hybridization techniques, are also within the scope of this disclosure. For example, it is envisaged that tobacco plants can be genetically engineered or crossed to increase or decrease the production of components, characteristics, or attributes.

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

In some embodiments, the tobacco material is a modulated or unmodified mixture of flue-cured tobacco, burley tobacco, and oriental tobacco.

In some embodiments, the tobacco material is selected from Brazilian tobacco, including Mata Fina and Bahia tobacco. In some embodiments, the tobacco material is selected from the group consisting of criollo, piloto Cubano, Olor, Green River, Isabela DAC, white White Pata, Eluru, Jatim, Madura, Kasturi, Connecticut Seed, Broad Leaf ), Connecticut, Pennsylvania, Italian dry-aired tobacco, Paraguayan dry-aired tobacco and One Sucker tobacco.

To prepare smoking/e-cigarette smoking or smokeless tobacco products, plants of Nicotiana species can be prepared. Certain types of tobacco can undergo alternative types of brewing processes, such as fire roasting or sun drying. Preferably, but not necessarily, the harvested conditioned tobacco is aged.

Tobacco can be harvested at different growth stages, for example when the plant reaches maturity and the lower leaves are ready to be harvested while the upper leaves are still developing.

In some embodiments, at least a portion of the Nicotiana species plant (e.g., at least a portion of the tobacco material) is employed 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 considered ripe or mature.

In some embodiments, at least a portion of the Nicotiana species plant (e.g., at least a portion of the tobacco material) is employed in a mature form. That is, in some embodiments, when a plant (or plant part) reaches a point that is traditionally regarded as ripe, over-ripe or mature, the plant or at least a part of the plant is harvested, which can be used by farmers. Tobacco harvesting technology is done. Both Oriental tobacco and Burley tobacco plants can be harvested. In addition, Virginia tobacco leaves can be harvested or initially processed depending on the position of the stem.

Nicotiana species can be selected based on 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 to be isolated (i.e., volatile compounds of interest). In certain embodiments, Nicotiana species plants are specially cultivated for their rich leaf surface compounds. Tobacco plants can be grown in greenhouses, growing rooms, or outdoor fields, or grown by hydroponics.

Various parts of the tobacco plant 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, multiple parts or pieces of the plant are harvested or separated for further use after harvest. In some embodiments, the tobacco material is selected from the leaves, stems, stalks and various combinations of these parts of the plant. Therefore, the tobacco material of the present disclosure may include the entire plant or any part of the plant of Nicotiana species.

In order to obtain the desired flavor profile, the tobacco composition used in the aerosol supply system, such as smoking products, usually contains tobacco material obtained from different parts of the tobacco plant, tobacco material obtained from different plants and already harvested A blend of post-processed tobacco materials.

The inventor of the present application surprisingly found that low-stem tobacco leaves containing more than 5% by weight of the tobacco material, that is, tobacco leaves with a weight ratio of sugar to nicotine between about 8:1 and about 20:1 When used in a flammable aerosol supply system, the tobacco material can be combined with aerosol former materials to obtain a tobacco composition with excellent organoleptic properties. Moreover, due to the relatively high content of low-stalk tobacco leaves in the tobacco material, the obtained tobacco composition has a very desirable light color compared with the conventional tobacco composition.

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 customized to change the organoleptic 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 customized to change the sensory characteristics of the composition.

In the composition described herein, when the amount is given in the form of% by weight, for the avoidance of doubt, unless specifically stated to the contrary, this means on a dry weight basis. Therefore, in order to determine the weight %, any water that may be present in the tobacco material or any of its components is completely disregarded.

Especially the flavor and taste of the tobacco material in the tobacco composition. Advantageously, this allows the use of various tobaccos that are conventionally considered to have desirable but subtle flavor characteristics in tobacco compositions.

In some embodiments, the aerosolizable material is an amorphous solid.

As previously mentioned, the aerosolizable material may include an aerosol former material. The aerosolizable material may include the aerosol forming agent material in an amount of about 1% to about 25% by weight or about 5% to about 20% by weight of the aerosolizable 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 %.

The aerosolizable material may include a binder. The binder can be selected from the group comprising alginate, pectin, starch (and derivatives), cellulose (and derivatives), glue, silica or polysiloxane, clay, polyvinyl alcohol, and combinations thereof Of one or more compounds. For example, in some embodiments, the binder includes alginate, pectin, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose, pullulan, xanthan gum, guarana One or more of gelatin, carrageenan, agarose, gum arabic, aerosol silica, PDMS, sodium silicate, kaolin and polyvinyl alcohol. In some cases, the binder includes alginate and/or pectin. In some embodiments, the binder includes alginate, such as sodium alginate.

The aerosolizable material may include a binder in an amount of 1% to about 15% by weight of the aerosolizable material. In some embodiments, the binder is present in an amount of about 5% to about 10% by weight or about 7% to about 9% by weight of the aerosolizable material.

The aerosolizable material may include inorganic materials. The inorganic material may comprise or consist of one or more metal carbonates, such as calcium carbonate or magnesium carbonate. Alternatively, the inorganic material may be a mixture of metal carbonates (such as magnesium carbonate or calcium carbonate), metal oxides (such as calcium oxide or magnesium oxide), and/or metal sulfates (such as calcium sulfate). The inorganic material may be a mineral containing one or more metal carbonates. In some embodiments, the inorganic material is chalk.

The aerosolizable material may include an inorganic material in an amount of about 50% by weight to about 90% by weight, about 60% by weight to about 85% by weight, or about 75% by weight to about 80% by weight of the aerosolizable material.

In some embodiments, the aerosolizable material includes an aerosol former material, a binder, and an inorganic material or is composed of an aerosol former material, a binder, and an inorganic material. In some embodiments, the aerosolizable material comprises an aerosol forming agent material in an amount of about 10% to about 20% by weight based on the total weight of the aerosolizable material, based on the total weight of the aerosolizable material The adhesive in an amount of about 1% to about 10% by weight and an inorganic material in an amount of about 75% to about 85% by weight based on the total weight of the aerosolizable material.

The aerosolizable material may contain any flavoring agent described herein.

In some embodiments, the aerosolizable material comprises tobacco extract. Tobacco extracts can be prepared by any method known to those skilled in the art. The inclusion of tobacco extract in the aerosolizable material can further enhance the flavor of the tobacco composition.

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 tobacco composition 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, it visually mixes with 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 tobacco composition can be customized to obtain any desired color. For example, materials configured to change the appearance of the tobacco composition, such as coloring agents, can be applied to some or all of the tobacco composition. In some embodiments, the material configured to change the appearance of the tobacco composition is applied to the tobacco material and/or aerosolizable material alone (e.g., before blending such materials). The material configured to change the appearance of the tobacco composition can be applied to the tobacco composition after or during the blending of the aerosolizable material and the tobacco material. The material configured to change the appearance of the tobacco composition can be applied, for example, by spraying.

The aerosolizable material can be combined with the tobacco material to form a tobacco composition. Optionally, the tobacco composition may include tobacco leaves containing sugar and nicotine in a weight ratio of about 8:1 to about 20:1, in an amount of at least 5% by weight of the tobacco material.

The aerosolizable material can be formed into pieces of material, and then cut or shredded into separate pieces or portions of material. The thickness of the material piece and the material portion shredded therefrom may be about 0.015 mm to about 1.0 mm. Suitably, the thickness may be about 0.05 mm, 0.1 mm or 0.15 mm to about 0.5 mm or 0.3 mm. In some embodiments, the thickness of the aerosolizable material may be about 0.45 mm to about 0.85 mm. The inventors have found that materials with a thickness of 0.5 mm are particularly suitable.

The aerosolizable material can be formed into a sheet of material, and then shredded for inclusion in the tobacco composition.

The cut width of the shredded aerosolizable tobacco material can range from about 0.5 cuts per millimeter to about 2.5 cuts per millimeter. In some embodiments, the cut width of the shredded aerosolizable material is about 0.8 to about 1.8 or about 0.9 to about 1.7 cuts per millimeter. In some embodiments, the cut width of the shredded aerosolizable material is about 1.4 to about 1.6 cuts per millimeter, or about 1.45 cuts per millimeter, or about 37 cuts per inch.

The cutting width of the shredded aerosolizable material may be about 0.2 to about 1 cut per millimeter, about 0.3 to about 0.9 cuts per millimeter, about 0.4 to about 0.8 cuts per millimeter, or about 0.5 to about 0.7 cuts per millimeter. Times cutting.

The aerosolizable material can be manufactured by: combining aerosol former materials, binders, and inorganic materials with a solvent (such as water); casting the slurry on a heated belt casting machine to produce a wet sheet; and The wet sheet is dried to obtain an aerosolizable material. The aerosolizable material can be further processed. For example, the aerosolizable material can be shredded.

Aerosolizable materials do not exhibit undesirable organoleptic properties when heated or burned. Therefore, the tobacco composition exhibits smooth and neutral flavor characteristics during smoking, and does not emit an excessively strong or unpleasant flavor. Without wishing to be bound by theory, it is assumed that this may be due to the aerosolizable material having a diluting effect on the smoke stream.

In some embodiments, the tobacco composition includes a flavoring agent. The inventors surprisingly discovered that the smooth and neutral flavor characteristics exhibited by the tobacco composition means that the user can more easily perceive the flavor. Therefore, it may be necessary to add less flavor to the composition to achieve the desired flavor profile. In addition, due to the relatively neutral sensory properties of the aerosol-generating material, flavors that are not traditionally used in, for example, cigarettes, such as flavors that exhibit subtle taste and/or aroma, may be used herein.

In some embodiments, the tobacco composition includes one or more flavors applied to the surface of the tobacco composition. The present inventors surprisingly found that when the tobacco composition contains a flavoring agent, the flavoring agent can be easily perceived by the user. 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 aerosolizable material in an amount of less than about 2000 ppm, such as about 100 ppm, 500 ppm, 1000 ppm, 1500 ppm. In some embodiments, one or more flavoring agents are at about 2000 ppm to 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 The amount added.

Instead of or in addition to being applied to the surface of the tobacco composition, flavoring agents can be incorporated into the aerosolizable material. For example, the aerosolizable material may include embedded flavors. Flavors can be added to the aerosolizable material during the manufacturing process. Advantageously, when the flavoring agent is included in the aerosolizable material, it can be released more slowly from the aerosolizable material than the flavoring agent included on the surface of the tobacco composition. This can extend the shelf life of the tobacco composition, and also extend the time to release the flavor during smoking of the product.

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

As used herein, the terms "flavour" and "flavourant" refer to products that can be used to produce desired taste, aroma or other body sensations in products intended for adult consumers when permitted by local regulations Material. It may include naturally occurring flavor materials, botanical medicinal materials, botanical medicinal extracts, synthetically obtained materials or combinations thereof (for example, tobacco, hemp, licorice, matcha, grapefruit, cappuccino, cranberry, star fruit, Hydrangea, eugenol, Japanese white magnolia leaf, chamomile, fenugreek, clove, maple, matcha, menthol, Japanese mint, anise (anise), cinnamon, turmeric, Indian spices, Asian spices, herbs , Holly, cherries, berries, cranberries, cranberries, peaches, apples, oranges, mangoes, citruses, lemons, limes, tropical fruits, papaya, rhubarb, grapes, durians, dragon fruits, cucumbers, blueberries, Mulberries, citrus fruits, Drambuie, Bourbon, Scotch, Whiskey, Gin, Tequila, Rum, Spearmint, Peppermint, Lavender, Aloe Vera, Cardamom, Celery, Sage, Nutmeg, sandalwood, bergamot, geranium, khat, naswar, betel nut, hookah, pine, honey extract, rose oil, vanilla, lemon oil, orange oil, orange blossom, cherry blossom, cinnamon , Caraway, cognac, jasmine, ylang-ylang, sage, fennel, wasabi, allspice, ginger, coriander, coffee, hemp, peppermint oil from any species of mint, eucalyptus, star anise, cocoa, Lemongrass, Dr. Louis tea (rooibos), flax, ginkgo, hazel, hibiscus, bay laurel, mate, orange peel, rose, tea such as green or black tea, thyme, juniper, elderflower, basil, moon Cinnamon leaves, cumin, oregano, paprika, rosemary, saffron, lemon peel, mint, perilla, turmeric, coriander leaves, myrtle, black currant, valerian, pepper tree, dried nutmeg, Damien, marjoram, olive, lemon balm, lemon basil, chives, caraway, verbena, tarragon, limonene, thymol, camphene), flavor enhancer, bitter receptor site blocker , Sensory receptor site activator or stimulant, sugar and/or sugar substitutes (e.g., sucralose, potassium acesulfame, aspartame, saccharin, cyclamate, lactose, sucrose, glucose, fructose, sorbose Alcohol or mannitol) and other additives such as charcoal, chlorophyll, minerals, botanicals or breath fresheners. It can be imitation, synthetic or natural ingredients or blends thereof. It can be in any suitable form, such as liquid (such as oil), solid (such as powder) or gas.

In some embodiments, the flavoring agent includes menthol, spearmint, and/or peppermint. In some embodiments, the flavoring agent includes flavor components of cucumber, blueberry, citrus fruit and/or cranberry. In one 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 comprises flavor components extracted from hemp.

In some embodiments, flavoring agents may include sensory agents, which are intended to achieve somatosensory sensations, which in addition to or in place of aroma or taste nerves, are usually chemically induced and by stimulating the fifth cranial nerve (trigeminal nerve). Sensitive, and such sensation agents may include agents that provide heating, cooling, tingling, and numbing effects. Suitable heat effect agent can be but not limited to vanillyl ethyl ether, and suitable cooling agent can be but not limited to cineole, WS-3.

In the case where the tobacco composition contains the aerosolizable material and flavor or sensation as described herein, the aerosolizable material can enhance the user’s perception of The perception of flavors or sensates. Without wishing to be bound by theory, it is believed that the relatively neutral flavor profile of the aerosolizable material means that it can act as a "flavor carrier" and enhance other flavors or sensations.

The consumables may include tobacco compositions. Consumables are products containing or composed of aerosol-generating materials, part or all of which are intended to be consumed by users during use. The consumables may include one or more other components, such as aerosol generating material storage area, aerosol generating material delivery component, aerosol generating area, housing, packaging, mouthpiece, filter, and/or aerosol modifier. The consumables may also include an aerosol generator, such as a heater, which emits heat during use to cause the aerosol generating material to generate an aerosol. The heater may, for example, comprise combustible materials, materials that can be heated by electric conduction, or susceptors.

The susceptor is a material that can be heated by penetrating it with a changing magnetic field (such as an alternating magnetic field). The susceptor can be a conductive material, so its penetration with a variable magnetic field will cause induction heating of the heating material. The heating material can be a magnetic material, so its penetration with a fluctuating magnetic field will cause hysteresis heating of the heating material. The susceptor can be conductive and magnetic, so the susceptor can be heated by two heating mechanisms. A device configured to generate a variable magnetic field is referred to herein as a magnetic field generator.

The consumable may be a combustible aerosol supply system containing the tobacco composition as described herein. Consumables can be used in non-aerosol supply systems instead.

Fig. 1 is a schematic diagram of a consumable 1a, which is generally cylindrical. The delivery system includes a strip 2 which contains the tobacco composition as described herein and is wrapped in a packaging material 3 (in this example, cigarette paper), by a tipping material 5 that covers the filter 4 and partially covers the packaging material 3 longitudinally Connect to the filter 4 in order to connect the filter 4 to the strip 2. The filter contains an absorbent material 7 and is wrapped in a forming paper 8.

A series of packaging materials can be suitable for packaging tobacco compositions. The packaging material can have various colors. In some embodiments, the color of the packaging material can be selected to match or coordinate with the tobacco composition. The packaging material can also be translucent or transparent, so that the user can identify the tobacco composition in the consumable. For example, the tobacco composition can have a unique appearance, which can be seen by the user through a transparent or translucent packaging.

As described herein, the tobacco composition may include tobacco materials and aerosolizable materials. In some embodiments, the distribution of tobacco material and aerosolizable material in the rod 2 is uniform. Alternatively, the distribution of tobacco material and aerosolizable material in the bar 2 is not uniform. The concentration of the aerosolizable material in the tobacco composition can vary along the length of the rod 2. For example, the closer the aerosolizable material is to the mouthpiece, the higher the concentration it can exist. This can improve the smoothness of the aerosol produced by the consumable at the end of the suction. In the case where the aerosolizable material contains flavors, the aerosol produced by the consumables at the end of the puffing can have a particularly high concentration of flavors, thereby changing (for example, improving) the consumables at the end of the puffing. Feeling characteristics.

In this example, the axis area is an area centered on the axis "a" of the delivery system 1a, and its radius is about 3 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 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, or 3.5 mm.

The axis of the delivery system 1a to which the tobacco rod 2 and the filter 4 are aligned is denoted as "a" in FIG. 1.

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

The component symbols from the embodiment shown in FIG. 1 and described previously are retained.

A capsule 9 is provided in the filter 4. The capsule contains an aerosol modifier, which changes the characteristics of mainstream smoke 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 flavor, but other fluid or granular additives may also be included in the capsule.

The capsule 9 may be a breakable capsule, such as a capsule having a solid, fragile shell surrounding a liquid payload. The consumer can rupture the capsule 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 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 disposed 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 required number of capsules. 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, multiple material bodies 7 may be provided, each body containing one or more capsules.

The combustible aerosol supply system may include an aerosol modifier. Aerosol modifiers are substances usually located downstream of the aerosol generating zone, which are configured to change the aerosol produced when the tobacco composition is heated, for example by changing the taste, flavor, acidity or another characteristic of the aerosol.

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

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

As previously mentioned, the aerosol produced by the tobacco composition described herein exhibits relatively smooth and neutral sensory properties. The inventors have discovered that the tobacco composition does not tend to mask the aerosol modifiers present in the aerosol. This means that aerosols can act as "carriers" for aerosol modifiers. Therefore, the user can easily perceive the sensory characteristics of the aerosol modifier, and it may be necessary to add a lower amount of aerosol modifier to the tobacco composition to achieve the desired aerosol characteristics. Aerosols can be used to carry many different aerosol modifiers.

The aerosol modifier is provided in or on the aerosol modifier release component, which can be operated to selectively release the aerosol modifier. The aerosol modifier release component can be a capsule, thread or bead, or a package, such as wrapping paper, forming paper, tipping paper or cigarette paper.

In some embodiments, the aerosol modifier release component is a package containing the aerosol modifier, especially tipping paper. The tipping paper or any paper/package described herein may contain an aerosol modifier, such as a sensory material.

In some embodiments, the sensory material may include one or more of pH adjusters, stabilizers, and/or antioxidants. These materials can help extend the storage period of the packaging, thereby extending the storage period 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, which are applied to tipping paper or other packaging materials. Encapsulation of aerosol modifiers can provide various advantages. For example, the encapsulated aerosol modifier may include or consist of a flavoring agent having a desired taste or aroma. Encapsulation can improve the persistence of taste and/or aroma.

In particular, the encapsulation of the aerosol modifier can enhance the persistence of the aroma of the aerosol modifier by enhancing the flavor detected by the user. Therefore, even after the flavor is weakened (for example, when the flavor is no longer detectable by the user or difficult to be detected by the consumer), the user can continue to detect the aroma, thereby enhancing the user's experience.

The encapsulated aerosol modifier can also help to mask other aromas that may be emitted by the components of the combustible aerosol supply system before or during its use.

The encapsulated aerosol modifier can exhibit aroma indicating the flavor of the aerosol modifier. For example, the fragrance can provide the user with a hint of the flavor of the sensory material. This can help the user to quickly put in the flavor of the sensate material.

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

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

The delivery system may comprise a single capsule, or it may comprise more than one capsule.

The shell of the capsule may contain an encapsulating material or a barrier material, which forms a shell around the core containing the aerosol modifier. The shell structure hinders the migration of the aerosol modifier during storage in the delivery system, but allows the controlled release of the aerosol modifier during use.

The barrier material (also referred to herein as the encapsulating material) is fragile. The user crushes or breaks or breaks the capsule in other ways 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 wants to release the core of the capsule, the shell can be broken under pressure from the user's fingers .

In some embodiments, the filter may include a capsule and a plurality of particles that are configured such that, in use, the particles promote the capsule when the user applies an external force to the wall of the tobacco industry product component. The particles may be made of a stronger (e.g. harder) material than the capsule shell. This helps to promote the rupture of the additive capsule when an external force is applied. The stronger particles also help prevent the capsule from breaking during transportation. A suitable arrangement 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 may be exposed to a temperature in the range of, for example, 30°C to 100°C, and the barrier material may continue to retain the liquid core until 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 by expanding the capsule to cause the barrier material to rupture.

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

The total weight of the capsule can 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 .

The total weight of the nuclear formulation may be in the range of about 2 mg to about 90 mg, suitably about 3 mg to about 70 mg, about 5 mg to about 25 mg, about 8 mg to about 20 mg, or about 10 mg to about 15 mg.

The barrier material may include one or more of a gelling agent, a buildup agent, a buffer, a coloring agent, and a plasticizer. Suitably, the gelling agent may be, for example, a polysaccharide or cellulose gelling agent, gelatin, gum, gel, wax or mixtures thereof. Suitable polysaccharides include alginate, polydextrose, maltodextrin, cyclodextrin and pectin. Suitable alginates include, for example, alginate, esterified alginate or glyceryl alginate. Alginates include ammonium alginate, triethanolamine alginate, and group I or group II metal ion alginates such as sodium alginate, potassium alginate, calcium alginate and magnesium alginate. Esterified alginates include propylene glycol alginate and glyceryl alginate. In one embodiment, the barrier material is sodium alginate and/or calcium alginate. Suitable cellulosic materials include methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose, cellulose acetate and cellulose ethers. The gelling agent may include one or more modified starches. The gelling agent may include carrageenan. Suitable gums include agar, gellan gum, acacia gum, pullulan gum, manna gum, gordi gum, tragacanth gum, Karaya gum (Karaya), locust bean gum, gum arabic, guar gum, quince Seeds and xanthan gum. Suitable gels include agar, agarose, carrageenan, furoidan and furcellaran. Suitable waxes include carnauba wax. In some cases, the gelling agent may include carrageenan and/or gellan gum; these gelling agents are particularly suitable for inclusion as gelling agents because the pressure required to rupture 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 the position of the capsule in the aerosol generating device more obvious during the manufacturing process of the aerosol generating device. The coloring agent is preferably selected from coloring agents and pigments.

The barrier material may further include at least one buffer, such as a citrate or phosphate compound.

The barrier material may further include at least one plasticizer, which may be glycerol, sorbitol, maltitol, triacetin, polyethylene glycol, propylene glycol or another polyol with plasticizing properties, and optional A mono-, di- or tri-acid type of acid, especially citric acid, fumaric acid, malic acid and the like. The amount of plasticizer ranges from 1% to 30% by weight of the total dry weight of the shell, preferably 2% to 15% by weight, and even more preferably 3% to 10% by weight.

The barrier material may also include one or more filler materials. Suitable filling materials include starch derivatives, such as dextrin, maltodextrin, cyclodextrin (α, β or γ), or cellulose derivatives, such as hydroxypropyl methylcellulose (HPMC), hydroxypropyl Base cellulose (HPC), methyl cellulose (MC), carboxymethyl cellulose (CMC), polyvinyl alcohol, polyhydric alcohol or mixtures thereof. Dextrin is the preferred filler. The amount of filler in the shell is at most 98.5 wt% of the total dry weight of the shell, preferably 25 wt% to 95 wt%, more preferably 40 wt% to 80 wt% and even more preferably 50 wt% to 60 wt%.

The capsule shell may additionally comprise a hydrophobic outer layer, which reduces the sensitivity of the capsule to moisture-induced degradation. The hydrophobic outer layer is suitably selected from the group comprising: wax (especially carnauba wax, candelilla wax or beeswax), carbowax, shellac (in alcoholic or aqueous solution), ethyl cellulose, hydroxy Propyl methyl cellulose, hydroxypropyl cellulose, latex composition, polyvinyl alcohol or a combination thereof. More preferably, the at least one moisture-proofing agent is ethyl cellulose or a mixture of ethyl cellulose and shellac.

The capsule core contains an aerosol modifier as previously described.

When the aerosol modifier is a flavoring agent, the flavoring agent is suitably licorice, rose oil, vanilla, lemon oil, orange oil, peppermint flavoring agent (preferably menthol and/or peppermint oil from any species of the genus Peppermint, Such as peppermint oil and/or spearmint oil), or lavender, fennel or star anise. In some cases, the flavoring agent includes menthol.

In some cases, the capsule may contain at least about 25% w/w flavor (based on the total weight of the capsule), suitably at least about 30% w/w flavor, 35% w/w flavor, 40% w/ w flavor, 45% w/w flavor or 50% w/w flavor.

In some cases, the core may comprise at least about 25% w/w flavor (based on the total weight of the core), suitably at least about 30% w/w flavor, 35% w/w flavor, 40% w/ w flavor, 45% w/w flavor or 50% w/w flavor. In some cases, the core may contain less than or equal to about 75% w/w flavoring agent (based on the total weight of the core), suitably less than or equal to about 65% w/w flavoring agent, 55% w/w flavoring agent, or 50% w/w flavoring agent. Illustratively, the capsule may include a flavor amount in the range of 25-75% w/w (based on the total weight of the core), about 35-60% w/w, or about 40-55% w/w.

The capsule may include at least about 2 mg, 3 mg or 4 mg aerosol modifier, suitably at least about 4.5 mg aerosol modifier, 5 mg aerosol modifier, 5.5 mg aerosol modifier Or 6 mg aerosol modifier.

In some cases, the capsule contains at least about 7 mg of aerosol modifier, suitably at least about 8 mg of aerosol modifier, 10 mg of aerosol modifier, 12 mg of aerosol modifier, or 15 mg of aerosol modifier. mg of aerosol modifier. The core may also include a solvent that dissolves the aerosol modifier. Any suitable solvent can be used.

In the case where the aerosol modifier includes a flavoring agent, the solvent may appropriately include short-chain or medium-chain fats and oils. For example, the solvent may comprise triglycerides, such as C2-C12 triglycerides, suitably C6-C10 triglycerides or Cs-C12 triglycerides. For example, the solvent may include medium chain triglycerides (MCT-C8-C12), which may be derived from palm oil and/or coconut oil.

These esters can be formed with caprylic acid and/or capric acid. For example, the solvent may include medium chain triglycerides, which are caprylic acid triglycerides and/or capric acid triglycerides. For example, the solvent may include compounds identified by numbers 73398-61-5, 65381-09-1, 85409-09-2 in the CAS registry. Such medium-chain triglycerides are odorless and tasteless.

The hydrophilic-lipophilic balance (HLB) of the solvent may be in the range of 9-13, suitably in the range of 10-12. The method of manufacturing capsules includes co-extrusion, optionally followed by centrifugation and curing and/or drying. The content of WO 2007/010407 A2 is incorporated by reference in its entirety.

The delivery device may include a filter. The filter may be located in the mouthpiece of the delivery device to filter the aerosol generated by the aerosol generating material during the use of the delivery device.

The filter may comprise a body of material. The body of material may comprise tows. The tow materials described herein may comprise cellulose acetate fiber tows.

The aerosolizable material was prepared 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 glycerol (13% by dry weight) were added to the mixture and mixed for 5 minutes. The mixture is stirred in the tank until the slurry reaches a uniform consistency. The slurry was then cast using a heated belt casting machine (casting width 800 mm; 80 to 90° C., 20 minutes) to produce a wet sheet about 0.5 mm thick. Subsequently, a shredder is used to shred the aerosolizable material at 37 cuts per inch (approximately 1.5 cuts per millimeter) to obtain a shredded aerosolizable material. Example 2

The aerosolizable material produced according to Example 1 was blended with the tobacco material to produce a tobacco composition containing tobacco and aerosolizable material. The relative amounts of aerosolizable materials and tobacco materials in the tobacco composition are shown in Table 1.

The tobacco composition contains tobacco leaves in an amount of about 50% by weight based on the total weight of the composition. About 40% by weight of tobacco leaves are leaves obtained from the lower half of the tobacco plant, and the ratio of sugar to nicotine is about 10:1. The tobacco composition contains tobacco stems in an amount of about 18% by weight based on the total weight of the composition. Table 1 Tobacco composition Aerosolizable material (wt%) 37% Tobacco material (wt%) 63% Example 3

The tobacco composition produced according to Example 2 was made into cigarettes. Cigarettes containing tobacco components can be sold under the name "white tobacco".

Use aerosol-generating materials to make three cigarettes with filters. A cigarette does not contain any additional flavors. The other two cigarettes contain flavor (menthol, 1 mg).

The configuration 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

A panel of professional smokers evaluated the sensory characteristics of cigarettes 1 to 3 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, cigarettes 1 to 3 showed better aftertaste, better flavor perception and better mouthfeel than the control cigarettes.

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