detailed description

The tobacco composition can be used in delivery systems, including combustible and non-combustible aerosol delivery systems. Tobacco compositions can include non-tobacco materials as well as tobacco materials.

As used herein, the term "delivery system" is intended to encompass systems that deliver at least one substance to a user, including:
Combustion-type aerosol delivery systems, such as cigarettes, cigarillos, cigars, and tobacco (tobacco, tobacco derivatives, puffed tobacco, reconstituted tobacco, tobacco substitutes or other smoking wood-based or not);
Non-combustion aerosol delivery systems that release a compound from the aerosol-generating material without combusting the aerosol-generating material, such as electronic cigarettes, tobacco heating products, and hybrid systems that generate an aerosol using certain combinations of aerosol-generating materials;
Aerosol-free delivery systems that deliver at least one substance orally, nasally, transdermally or otherwise to a user without generating an aerosol, including but not limited to drops, gums, patches, inhalers Possible powder-containing articles and oral articles such as chewing tobacco, including snus or moist snuff, wherein the at least one substance may or may not contain nicotine.

According to this disclosure, a "combustion-type" aerosol delivery system is one in which an aerosol-generating material that is a component of the aerosol delivery system (or a component thereof) is used to facilitate delivery of at least one substance to a user. ignited or combusted.

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

In some embodiments, the present disclosure provides components for use in combustion-type aerosol delivery systems such as filters, filter rods, filter segments, tobacco rods, spills, aerosol modifier releasing components such as capsules, threads or beads. , or paper, such as plug wrap, tipping paper or cigarette paper.

According to this disclosure, a "non-combustible" aerosol delivery system is one in which the aerosol-generating materials of the components of the aerosol delivery system (or components thereof) are combusted to facilitate delivery of at least one substance to a user. not burn or burn.

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

In some embodiments, the non-combustion aerosol delivery system is an electronic cigarette, also referred to as a vaping device or electronic nicotine delivery system (END), although the presence of nicotine in the aerosol-generating material is said not to be a requirement. .

In some embodiments, the non-combustion aerosol delivery system is an aerosol-generating material heating system, also referred to as a non-combustion heating system. One example of such a system is a tobacco heating system.

In some embodiments, the non-combustion aerosol delivery system is a hybrid system that uses a combination of aerosol-forming materials, one or more of which may be heated, to produce the aerosol. Each aerosol-generating material may, for example, be in the form of a solid, liquid or gel, and may or may not contain nicotine. In some embodiments, the hybrid system includes a liquid or gel aerosol-generating material and a solid aerosol-generating material. Solid aerosol-generating materials may include, for example, tobacco or non-tobacco products.

Typically, a non-combustion aerosol delivery system may include a non-combustion aerosol delivery device and consumables used with the non-combustion aerosol delivery device.

In some embodiments, the present disclosure relates to consumables that include an aerosol-generating material and are configured for use with non-combustion aerosol delivery devices. These consumables are sometimes referred to as articles throughout this disclosure.

In some embodiments, a non-combustion aerosol delivery system, eg, a non-combustion aerosol delivery device thereof, may include a power source and a controller. The power source can be, for example, a power source or a heat generating power source. In some embodiments, the exothermic power source includes a carbon substrate that can be activated to deliver output in the form of heat to an aerosol-generating material or heat transfer material proximate the exothermic power source.

In some embodiments, a non-combustion aerosol delivery system can include a consumable receiving area, an aerosol generator, an aerosol generating area, a housing, a mouthpiece, a filter, and/or an aerosol modifier.

In some embodiments, consumables used with non-combustible aerosol delivery devices include aerosol-generating materials, aerosol-generating material storage areas, aerosol-generating material delivery components, aerosol generators, aerosol-generating areas, housings, wrappers, filters. , a mouthpiece, and/or an aerosol modifier.

In some embodiments, the delivery system is an aerosol-free delivery system that delivers at least one substance to a user orally, nasally, transdermally, or otherwise without forming an aerosol, e.g. This includes, but is not limited to, oral products such as drops, gums, patches, articles containing inhalable powders, and chewing tobacco, including snus or moist snuff.

Tobacco plants include stems and tobacco leaves. During growth, tobacco plants produce various chemical compounds, including carbohydrate species (eg, sugars and starches) and nicotine. Sugars are also produced during the curing of some varieties of tobacco plants.

As used herein, the terms "sugar" and "sugars" are intended to cover all sugars, including reducing sugars (eg glucose and fructose) and non-reducing sugars (eg starch).

The sugar to nicotine ratio varies throughout the tobacco plant. The leaf sugar to nicotine ratio generally decreases from leaves in the lower areas of the plant to leaves in the higher areas of the plant. Thus, leaves in the lower portion of the tobacco plant (e.g., the lower half of the plant) have a relatively high ratio of sugars to nicotine compared to leaves in the upper region (e.g., the upper third) of the tobacco plant. including. The youngest tobacco leaves are found in the upper region of the tobacco plant, while the oldest tobacco leaves are found in the lower region of the tobacco plant. Generally, the leaves of the bottom half of the tobacco plant contain less sugar than the leaves of the top half of the tobacco plant, because the sugars in the bottom half of the plant are transported to the leaves in the top half of the plant to aid in growth and flowering.

The sugar to nicotine ratio and total sugar content of a tobacco material have an effect on the organoleptic properties of the tobacco material when an aerosol is produced in the aerosol delivery system. For example, sugars may be converted to other compounds exhibiting desirable organoleptic properties during processing of the tobacco material.

Although it is desirable that the tobacco material contain sugars, a relatively high sugar-to-nicotine content can result in a "too strong" flavor and/or pungency when smoked, which may be undesirable. As a result, lower petiole and mid-stalk leaves, which contain relatively high sugar-to-nicotine ratios, constitute minor components (less than 5 wt%) of conventional tobacco compositions used in conventional combustion-type aerosol delivery systems. do.

As used herein, the term "tobacco material" refers to material derived from plants of the Nicotiana species. The selection of Nicotiana species plants is not limited and the type of tobacco or tobacco used may vary.

In some embodiments, the tobacco material is pipe-cured or Virginia, Burley, sun-cured, Maryland, dark-fire-cured, dark-air-cured, light-air-cured, Indian air-cured, Red Rusian and Rustica tobaccos, and mixtures thereof. , as well as a variety of other fresh-leaf or dried rare or specialty tobaccos. Any other type of tobacco treatment capable of modifying the taste of tobacco, such as fermented tobacco or tobacco material produced by genetic engineering or crossbreeding techniques, is also within the scope of this disclosure. For example, tobacco plants could be genetically engineered or crossbred to increase or decrease component production, traits or attributes.

In some embodiments, the tobacco material is sun-cured tobacco selected from Indian Kurnool and Oriental tobaccos, such as Izmir, Basma, Samsun, Katerini, Prelip, Komotini, Xanti and Yambol tobaccos. In some embodiments, the tobacco material is a dark air-cured tobacco selected from Passanda, Cubano, Jatin and Veschi tobacco. In some embodiments, the tobacco material is light air-cured tobacco selected from North Wisconsin and Gulpao tobaccos.

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

In some embodiments, the tobacco material is selected from Brazilian tobacco, such as Matafina and Bahia tobacco. In some embodiments, the tobacco material is Criollo, Piloto Cubano, Olau, Green River, Isabella DAC, White Pata, Ehrul, Jatin, Madura, Castri, Connecticut Seeds, Broadleaf, Connecticut, Pennsylvanian, Italian Dry Air Dry, Paraguay Selected from uncured air cured and onesucker tobacco.

For the preparation of smoking/vaping or smokeless tobacco products, plants of the Nicotiana species may be subjected to a drying process. Certain types of tobacco may be subjected to another type of curing process, such as fire-curing or sun-curing. Preferably, but not necessarily, the dried and harvested tobacco is aged.

Tobacco can be harvested at various stages of growth, for example when the plant reaches a certain level of maturity and the lower leaves are ready for harvesting while the upper leaves are still developing.

In some embodiments, at least a portion of the Nicotiana species plant (eg, at least a portion of the tobacco material) is used in immature form. That is, in some embodiments, the plant, or at least a portion of the plant, is harvested before reaching a stage that would normally be considered full ripeness or maturity.

In some embodiments, at least a portion of the Nicotiana species plant (eg, at least a portion of the tobacco material) is used in mature form. That is, in some embodiments, the plant, or at least a portion of the plant, is harvested when the plant (or plant part) reaches a point traditionally considered full ripeness, overripe, or maturity, which the farmer can be achieved through the use of tobacco harvesting techniques conventionally used by Both Oriental and Burley tobacco plants can be harvested. Virginia tobacco leaves can also be harvested, or the lower leaves can be harvested depending on the position of the petiole.

Nicotiana species can be selected for the content of various compounds present in the plant. For example, plants may be selected based on the fact that they produce relatively high amounts of the compound or compounds that it is desired to isolate (ie, the volatile compounds of interest). In certain embodiments, plants of the Nicotiana species are cultured specifically for leaf surface compound richness. Tobacco plants can be grown in greenhouses, grow boxes, or in outdoor fields, or can be grown hydroponically.

Various organs or parts of plants of the Nicotiana species can be used in the methods defined herein. In some embodiments, whole plants, or substantially whole plants, are harvested and used as is. As used herein, the term "substantially the whole 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 organs or pieces of the plant are harvested or separated after harvest for further use. In some embodiments, the tobacco material is selected from plant leaves, stems, petioles, and various combinations of these organs. As such, the tobacco material of the present disclosure may comprise a whole plant of the Nicotiana species or any part of the plant.

To achieve the desired flavor profile, tobacco compositions used in combustion-type aerosol delivery systems, e.g. Includes blends of tobacco materials that have been subjected to subsequent processing.

The inventors of the present application have surprisingly found that lower petiole tobacco, i.e., leaf tobacco having a weight ratio of sugars to nicotine of from about 8:1 to about 20:1, is used in an amount greater than 5% by weight of the tobacco material. It has been found that the tobacco material comprising, when combined with an aerosol-forming material, can provide a tobacco composition having superior sensory properties when used in a combustion-type aerosol delivery system. Moreover, as a result of the relatively high content level of lower petiole tobacco in the tobacco material, the resulting tobacco composition has a highly desirable light color compared to conventional tobacco compositions.

The tobacco material can be a blend of different species of tobacco material and/or tobacco material that has been treated according to a tobacco treatment process. The tobacco material blend can be tailored to alter the sensory characteristics of the aerosol produced during use of the combustion-type aerosol delivery system. For example, the relative amounts of different varieties of tobacco material in the composition can be adjusted to alter the organoleptic properties of the composition.

In compositions described herein where amounts are given in weight percent, this, for the avoidance of doubt, refers to a dry weight basis unless indicated to the contrary. Therefore, any water that may be present in the tobacco material, or any component thereof, is completely ignored for purposes of weight percent determination.

For example, in some embodiments, the binder is alginate, pectin, hydroxyethylcellulose, hydroxypropylcellulose, carboxymethylcellulose, pullulan, xanthan gum, guar gum, carrageenan, agarose, gum acacia, fumed silica, PDMS, sodium silicate, kaolin. and polyvinyl alcohol. Optionally, binders include alginate and/or pectin. In some embodiments, the binder comprises an alginate, such as sodium alginate.

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

Aerosol-generating materials 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 or magnesium oxides, and/or metal sulfates, such as calcium sulfate. The inorganic material can be a mineral containing one or more metal carbonates. In some embodiments, the inorganic material is chalk.

The aerosol-generating material can include inorganic materials in amounts of about 50% to about 90%, about 60% to about 85%, or about 75% to about 80% by weight of the aerosol-generating material.

In some embodiments, the aerosol-generating material comprises or consists of an aerosol-forming agent, a binder and an inorganic material. In some embodiments, the aerosol-generating material comprises an aerosol-forming agent in an amount of about 10 wt% to about 20 wt%, based on the total weight of the aerosol-generating material, and a binder, based on the total weight of the aerosol-generating material. The inorganic material is included in an amount of about 1 wt% to about 10 wt% and in an amount of about 75 wt% to about 85 wt% based on the total weight of the aerosol-generating material.

Aerosol-generating materials can include any of the perfumes described herein.

In some embodiments, the aerosol-generating material comprises tobacco extract. Tobacco extracts may be prepared by any means known to those skilled in the art. Including tobacco extract in the aerosol-generating material may further enhance the flavor of the tobacco composition.

In some embodiments, the aerosol-generating material does not contain a colorant. Alternatively, the aerosol-generating material may contain a coloring agent. Colorants can change the appearance of the aerosol-generating material. The presence of colorants in the aerosol-generating material can enhance the appearance of tobacco compositions containing the aerosol-generating material. For example, the aerosol-generating material can be toned with the tobacco material so that it visually blends with the tobacco material when the two materials are combined. The aerosol-generating material can be white, green, blue, brown or black in color. In preferred embodiments, the aerosol-generating material is white in color.

In some embodiments, the color of the tobacco composition can be adjusted to achieve the desired color. For example, substances configured to alter the appearance of the tobacco composition, such as colorants, may be applied to some or all tobacco compositions. In some embodiments, the substance configured to alter the appearance of the tobacco composition is applied separately to the tobacco material and/or the aerosol-generating material (eg, prior to blending these materials). A substance configured to alter the appearance of the tobacco composition may be applied to the tobacco composition after or during blending of the aerosol-generating material and the tobacco material. Substances designed to alter the appearance of tobacco compositions can be applied, for example, by spraying.

The aerosol-generating material can be combined with tobacco material to form a tobacco composition. Optionally, the tobacco composition may comprise leaf tobacco in an amount of at least 5% by weight of the tobacco material, comprising sugars and nicotine in a weight ratio of about 8:1 to about 20:1.

The aerosol-generating material can be formed as a sheet of material and then cut or chopped into separate individual segments or portions of material. The sheet of material, and thus the portion of material engraved, can have a thickness of about 0.015 mm to about 1.0 mm. Suitably the thickness may be from about 0.05 mm, 0.1 mm or 0.15 mm to about 0.5 mm or 0.3 mm. In some embodiments, the aerosol-generating material can have a thickness of about 0.45mm to about 0.85mm. The inventor has found that a material having a thickness of 0.5 mm is particularly suitable.

The aerosol-generating material can be formed as a sheet of material and then chopped for inclusion in the tobacco composition.

The cut width of the chopped aerosol-generating material tobacco material can be from about 0.5 cuts/mm to about 2.5 cuts/mm. In some embodiments, the cut width of the engraved aerosol-generating material is from about 0.8 to about 1.8 or from about 0.9 to about 1.7 cuts/mm. In some embodiments, the cut width of the engraved aerosol-generating material is about 1.4 to about 1.6 cuts/mm, or about 1.45 cuts/mm, or about 37 cuts/inch.

The minced aerosol-generating material has about 0.2 to about 1 cut/mm, about 0.3 to about 0.9 cut/mm, about 0.4 to about 0.8 cut/mm, or about 0.5 to about 0.8 cut/mm. It may have a cut width of about 0.7 cuts/mm.

Aerosol-forming materials are prepared by combining an aerosol-forming agent, a binder, and an inorganic material with a solvent, such as water; casting the slurry onto a heated band caster to form a wet sheet; and drying the wet sheet to form an aerosol. It can be manufactured by providing a flexible material. Aerosol-generating materials may be further processed. For example, an aerosol-generating material may be chopped.

Aerosol-forming materials do not exhibit undesirable sensory properties when heated or combusted. Accordingly, the tobacco composition exhibits a smooth, neutral flavor profile when smoked and does not release strong or unpleasant flavors. While not wishing to be bound by theory, it is hypothesized that this may be due to the aerosol-forming material having a diluting effect on the smoke stream.

In some embodiments, the tobacco composition comprises flavoring. The inventor has surprisingly found that the smooth, neutral flavor profile exhibited by the tobacco composition means that the flavor can be more readily perceived by the user. Accordingly, less flavorant may be added to the composition to achieve the desired flavor profile. Also, flavorants not commonly used in, for example, cigarettes may be used, such as flavorants that exhibit subtle tastes and/or odors due to the relatively neutral organoleptic properties of the aerosol-generating materials described herein. it may be possible to

In some embodiments, the tobacco composition comprises one or more flavoring agents applied to the surface of the tobacco composition. The inventor has surprisingly found that when the tobacco composition contains a flavor, the flavor can be readily perceived by the user. Accordingly, relatively small amounts of flavoring agents may need to be added to the composition to achieve the desired flavor characteristics. For example, one or more perfumes can be added to the aerosol-generating material and/or aerosol-generating 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 fragrances are added in an amount from 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.

Flavoring agents may be incorporated into the aerosol-generating material instead of, or in addition to, being applied to the surface of the tobacco composition. For example, an aerosol-generating material may contain an embedded perfume. Perfume may be added to the aerosol-generating material during its manufacture. Advantageously, when flavorants are contained within the aerosol-generating material, they may be released from the aerosol-generating material more slowly than flavorants contained on the surface of the tobacco composition. This can extend the shelf life of the tobacco composition and can also extend the period of flavor release during smoking of the article.
Perfume can be added to the aerosol-generating material in an amount of about 0.01% to about 0.1% by weight of the aerosol-generating material.

As used herein, the terms "perfume" and "flavourant" refer to any ingredient that, where permitted by local regulations, is used to produce a desired taste, aroma, or other somatosensory perception in products intended for adult consumers. Refers to materials that may be used.

They can be imitations, synthetic or natural ingredients or blends thereof. They may be in any suitable form, for example liquids such as oils, solids such as powders, or gases. In some embodiments, flavorants include menthol, spearmint and/or peppermint. In some embodiments, the flavoring agent comprises cucumber, blueberry, citrus and/or redberry flavoring ingredients. In one embodiment, the flavor is cappuccino. In some embodiments, the perfume comprises eugenol. In some embodiments, the flavoring agent comprises flavoring ingredients extracted from tobacco. In some embodiments, the flavoring agent comprises flavoring ingredients extracted from cannabis.

In some embodiments, flavoring agents may include sensates, which are intended to achieve somatosensory perception, which are usually chemically induced, and which are used in addition to or instead of scent or taste nerves. They are perceived by stimulation of the fifth cranial nerve (trigeminal nerve) and can include agents that produce heating, cooling, tingling, and numbing effects. A suitable heating effect agent may be, but is not limited to, vanillyl ethyl ether, and a suitable cooling agent may be, but not limited to, eucoliptol, WS-3.

When a tobacco composition comprises an aerosol-generating material as described herein and a flavoring or sensate agent, the aerosol-generating material is less sensitive to the user's flavor or sensibility than a tobacco composition without the aerosol-generating material. May enhance perception of agents. While not wishing to be bound by theory, it is believed that the relatively neutral flavor profile of the aerosol-generating material means that it can serve as a "flavor carrier" to enhance other flavor or sensate agents. be done.

Consumables may include tobacco compositions. A consumable is an article that contains or consists of an aerosol-generating material, some or all of which is intended to be consumed during use by a user. A consumable may include one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material delivery component, an aerosol-generating area, a housing, a wrapper, a mouthpiece, a filter, and/or an aerosol modifier. Consumables can also include aerosol generators, such as heaters, that emit heat that causes the aerosol-generating material to generate an aerosol when in use. The heater can include, for example, a combustible material, a conductively heatable material, or a susceptor.

A susceptor is a material that can be heated by penetration by a varying magnetic field, such as an alternating magnetic field. The susceptor can be an electrically conductive material whose immersion by a fluctuating magnetic field causes inductive heating of the heating material. The heating material may be a magnetic material such that immersion thereof by a varying magnetic field causes magnetic hysteresis heating of the heating material. The susceptor can be a susceptor that is both electrically conductive and magnetic and thus heatable by both heating mechanisms. A device configured to generate a varying magnetic field is referred to herein as a magnetic field generator.

The consumable can be a combustion-type aerosol delivery system containing the tobacco compositions described herein. Alternatively, the consumable may be used with non-combustion aerosol delivery systems.

FIG. 1 is a schematic representation of a consumable 1a which is generally cylindrical in shape. The delivery system comprises a rod 2 containing a tobacco composition as described herein, the rod 2 being wrapped in a wrapping material 3, in this example cigarette paper, and longitudinally bounded by a tipping material 5 through a filter 4. , the tipping material 5 covers the filter 4 and partially covers the wrapping material 3 to connect the filter 4 to the rod 2 . The filter contains absorbent material 7 and is wrapped in plug wrap 8 .

A range of packaging materials may be suitable for enclosing the tobacco composition. The packaging material can have various colors. In some embodiments, the color of the packaging material may be selected to match or match the tobacco composition. The packaging material can also be translucent or transparent to allow the user to see the tobacco composition within the consumable. For example, the tobacco composition may have a unique appearance visible to the user through a transparent or translucent wrapper.

Tobacco compositions may include tobacco materials and aerosol-generating materials as described herein. In some embodiments, the distribution of tobacco material and aerosol-generating material within rod 2 is uniform. Alternatively, the distribution of tobacco material and aerosol-generating material within rod 2 is uneven. The concentration of aerosol-generating material in the tobacco composition can vary along the length of rod 2 . For example, the aerosol-generating material may be present at a higher concentration closer to the mouthpiece. This may improve the smoothness of the consumable-generated aerosol towards the end of the session. If the aerosol-generating material includes perfume, the aerosol generated by the consumable towards the end of the session may have a particularly high perfume concentration, thus altering (eg, improving) the sensory properties of the consumable towards the end of the session.

The axial region is, in this example, the region centered on the axis "a" of the delivery system 1a and having a radius of about 3 mm. In alternate embodiments, the radius of the axial region can be anywhere from 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 around which the tobacco rod 2 and filter 4 are arranged is shown as "a" in FIG.

FIG. 2 is a schematic diagram of a combustion-type aerosol delivery system 2a.

Reference numerals have been kept from the embodiment shown in FIG. 1 and have already been described.

A capsule 9 is provided in the filter 4 . The capsule contains an aerosol modifier that modifies the characteristics of mainstream smoke passing through the smoking article 2 . The capsule can be manufactured and inserted into filter 4 using existing processes and machinery. In this example the capsule contains menthol flavoring, but other fluid or granular additives could be contained within the capsule.

The capsule 9 can be a frangible capsule, eg a capsule with a solid frangible shell surrounding a liquid payload. The capsule can be ruptured by the consumer to release the fluid additive into the absorbent filter material 7 . The capsule 9 is completely embedded within the body of material 7 . In other words, capsule 9 is completely surrounded by the material forming body 7 .

A single capsule 9 is used in this example. In alternate embodiments, filter 4 may include one or more capsules. In another example, a plurality of frangible capsules, eg two, three or more frangible capsules, may be arranged within the body of material 7 . The length of the body of material 7 can be increased to accommodate the number of capsules required. In instances where multiple capsules are used, the individual capsules may be identical or different in size and/or capsule payload.

In other examples, multiple bodies of material 7 may be provided, each body containing one or more capsules.

A combustion-type aerosol delivery system may include an aerosol modifier. Aerosol modifying agents are configured to modify the aerosol produced by the tobacco composition when heated, for example by altering the taste, flavor, acidity or other property of the aerosol, typically in the aerosol-generating area. Substance placed downstream.

Aerosol modifiers can be, for example, additives or adsorbents. Aerosol modifiers may include, for example, one or more of fragrances, colorants, water, and carbon adsorbents. Aerosol modifiers can be, for example, solids, liquids, or gels. Aerosol modifiers may be in the form of powders, threads or granules. Aerosol modifiers may not contain filter media.

Preferred aerosol modifiers are flavorants and sensates as already described.

As previously mentioned, the aerosols produced by the tobacco compositions described herein exhibit relatively smooth and neutral sensory characteristics. The inventors have found that the tobacco composition does not tend to mask the aerosol modifier present in the aerosol. This means that the aerosol can act as a "carrier" for the aerosol modifier. Therefore, the organoleptic properties of the aerosol modifier can be more readily perceived by the user, and lower amounts of the aerosol modifier may need to be added to the tobacco composition to achieve the desired aerosol properties, resulting in a tobacco composition. Aerosols produced by can be used to carry a wide variety of different aerosol modifiers.

The aerosol modifier is provided in or on an aerosol modifier release component that may be operable to selectively release the aerosol modifier. The aerosol modifying agent release component can be a capsule, thread, or bead, wrapper such as paper wrapper, plug wrap, tipping paper or cigarette paper.

In some embodiments, the aerosol modifying agent release component is a wrapper, particularly tipping paper, containing the aerosol modifying agent. The tipping paper or any of the papers/wrappers described herein can include an aerosol modifier, such as a sensate material.

In some embodiments, sensate substances may include one or more of pH modifiers, stabilizers, and/or antioxidants. These materials can help increase the shelf life of the wrapper, and thus the combustion-type aerosol delivery system.

The aerosol modifier can be encapsulated within an encapsulant. For example, the sensate material can be provided in the form of microcapsules applied to a tipping paper or other wrapper. Encapsulation of aerosol modifiers can provide various advantages. For example, an encapsulated aerosol modifier can comprise or consist of a flavoring agent having a desired taste or aroma. Encapsulation can enhance taste and/or aroma longevity.

In particular, encapsulation of the aerosol modifier can improve the odor longevity of the aerosol modifier by enhancing the flavor detected by the user. Thus, the scent may enhance the user's experience by remaining detectable by the user even after the flavor has diminished (e.g., when the flavor is no longer detectable by the user or less than detectable by the consumer). .

Encapsulated aerosol modifiers can also help mask other scents that may be released by the components of the combustion-type aerosol delivery system before or during its use.

An encapsulated aerosol modifier may exhibit an odor indicative of the flavor of the aerosol modifier. For example, scent can provide a user with a cue to the flavor of a sensate substance. This can help the user quickly set up the flavor of the sensate substance.

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

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

The delivery system may contain a single capsule or may contain more than one capsule.

The shell of the capsule may comprise an encapsulant or barrier material that creates a shell around a core containing the aerosol modifier. The shell structure prevents migration of the aerosol modifier during storage of the delivery system, but allows controlled release of the aerosol modifier during use.

Barrier materials (also referred to herein as encapsulants) are fragile. The capsule is crushed or otherwise crushed or ruptured by the user to release the encapsulated aerosol modifier. Typically, the capsule is ruptured just before heating begins, but the user can choose when to release the aerosol modifier. The term "breakable capsule" refers to a capsule whose shell can be broken by pressure to release the core; Can burst under pressure.

In some embodiments, the filter may comprise a capsule and a plurality of particles configured such that the particles promote rupture of the capsule when an external force is applied by a user to the wall of the tobacco industry product component during use. The particles may be made of a material that is tougher (eg, harder) than the capsule shell. This helps facilitate breakage of the additive capsule when an external force is applied. Particles that are tougher also help prevent capsule breakage during transit. Suitable constructs are described in WO2019/207302.

Optionally, the barrier material is heat resistant. That is, optionally the barrier does not rupture, melt, or otherwise fail at temperatures reached at the capsule site during operation of the aerosol delivery device. By way of illustration, a capsule located in the mouthpiece may be exposed to temperatures in the range of, for example, 30°C to 100°C, and the barrier material may retain the liquid core until at least about 50°C to 120°C.

In other cases, the capsule releases the core composition upon heating, for example by melting of the barrier material or by swelling of the capsule leading to rupture of the barrier material.

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

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

The filter 4 comprises a first section 7a made of absorbent material and a fibrous filter material 11 formed into a tubular shape with a channel 12 extending through the center of the filter material 11 at the mouth side of the filter 4. It includes an end second section 10 . The empty or hollow channel 12 extending through the center of the filter material 11 can be 1 mm to 6 mm in diameter, such as 2 mm to 5 mm in diameter. Channel 12 extending through the center of filter material 11 is an empty hollow passageway in this example. The channels extend through the axial region of the filter material of the second filter section 10 in some embodiments. The axial region of the second filter section 10 is the region centered on the axis "a" of the smoking article 1 having a radius of approximately 2.5 mm in this example.

Example 1
The aerosol-generating material was made as follows. Water and sodium alginate (Protanal® RF6650; 8% on a dry weight basis) were combined and mixed in a high shear mixer for 15 minutes. Chalk (79% dry weight basis) and glycerol (13% dry weight basis) were added to the mixture and mixed for 5 minutes. The mixture was stirred in the tank until the slurry reached a uniform consistency. The slurry was then cast using a heated band caster (cast width 800 mm; 80-90°C, 20 minutes) to produce a wet sheet approximately 0.5 mm thick. The aerosol-generating material was then chopped using a chopper to 37 cuts/inch (about 1.5 cuts/mm) to obtain chopped aerosol-generating material.

Example 2
The aerosol-generating material produced according to Example 1 was blended with tobacco material to form a tobacco composition comprising tobacco and the aerosol-generating material. The relative amounts of aerosol-generating material and tobacco material in the tobacco composition are shown in Table 1.

The tobacco composition contained tobacco in an amount of about 50 wt% relative to the total weight of the composition. About 40 wt% of the tobacco leaves were leaves obtained from the lower half of the tobacco plant and had a sugar to nicotine ratio of about 10:1. The tobacco composition contained tobacco stems in an amount of about 18 wt% based on the total weight of the composition.

Example 3
A tobacco composition produced according to Example 2 was made into cigarettes. Cigarettes containing tobacco compositions may be marketed under the name "white tobacco."

Three cigarettes containing filters were manufactured using the aerosol-generating material. One cigarette did not contain any added flavorant. Two other cigarettes contained flavoring (menthol, 1 mg).

Table 2 shows the configuration.
