Detailed description

The present invention relates to components for the release of tobacco components, which are formed from tobacco particles. These components can release tobacco components that include flavoring materials and nicotine. They can also act as a carrier for other materials that need to be released. Tobacco release components are suitable for inclusion in various tobacco products.

At least some of the released components are directly derived from the tobacco particles used to form the components. In some embodiments, additional materials may be added to the release components. These additional materials may, for example, also contain tobacco components added in addition to those directly derived from tobacco particles. Alternatively or additionally, additional materials added to the release components may not be derived from tobacco.

For example, the components may also, in some embodiments, carry and release other flavoring materials, including those not derived from tobacco.

A tobacco release component included in a tobacco product may modify the aerosol generated by said product during use. A stream of air or aerosol passing over and/or through the component, optionally with heating, causes materials to be released from the component. Released materials may, in some embodiments, include tobacco components such as flavoring materials and flavoring materials, as well as other tobacco-derived materials such as nicotine and, if included in the tobacco component release component, non-tobacco-derived materials or which are not derived from tobacco particles included in the components.

Released materials are absorbed into the air or aerosol, modifying them. In some embodiments, the flavor, aroma, or flavor of an aerosol produced by a tobacco product is modified by a component to release tobacco ingredients. In some embodiments, the aerosol is enriched with natural tobacco flavoring and flavoring materials. Additionally or alternatively, the aerosol is modified with non-tobacco flavoring materials as a result of the inclusion of flavoring materials or sources of flavoring material in the tobacco release components. In additional embodiments, the aerosol can be modified by adding nicotine. In other additional embodiments, the taste experience of the aerosol can be modified with materials such as aerosol agents released by tobacco release components.

Components for the release of tobacco components are agglomerated structures formed from a precursor composition that contains tobacco particles. This means that the components represent a mass or aggregate formed as a result of combining or gluing several particles with each other. The constituent particles include tobacco particles. In some embodiments, particles of other materials may also be included.

An important aspect of the present invention is that the release of materials from the tobacco release components can be controlled and tailored to the specific requirements of the tobacco product in which they are to be incorporated. In particular, it is desirable to control the rate and degree of release. The release of materials is a key factor in providing the desired flavor profile when using a tobacco product, as well as the desired sensory experience. In particular, it may be desirable to monitor the rate of release once the product has been used, the duration of release, and the uniformity of release. It is also important to ensure that a substantial proportion of the release materials contained in the tobacco ingredient release component are actually released during normal use of the tobacco industry product.

A component for releasing tobacco ingredients is provided that includes an agglomerated structure formed from a precursor composition containing tobacco particles, wherein the release of tobacco ingredients upon heating the component without combustion is controlled by adjusting one or more of the following: (a) surface area to volume ratio he component; and (ii) the amount of the intended agent(s) for the formation of an aerosol.

To improve the release of tobacco constituents and other materials from the component during use in a tobacco product (in which the component is heated without combustion), it is desirable for the component to have a high surface area to volume ratio.

The increased surface area of the component for releasing tobacco ingredients increases the release of tobacco ingredients and other materials. The increased surface area to volume ratio means that more of the tobacco components and other materials will be located closer to the surface of the component, causing them to heat up and release faster, and a larger fraction is released. In the context of this document, increased surface area or increased surface area to volume ratio refers to a comparison to the surface area of a solid structure that is approximately spherical and has the shape of a cylindrical rod or the same volume.

As described in more detail below, the shape of the components for the release of tobacco components can be chosen to increase the ratio of surface area to volume, for example, by increasing the surface area by creating wavy or uneven surfaces or by creating channels in the components. It is desirable to reduce the distance from the surface of the component 60 to the tobacco components and other materials to be released, so that as much of these materials as possible can be released during use of the tobacco industry product, rather than remaining trapped in the agglomerated structure. The increased proximity of the tobacco ingredients and other materials to the surface of the tobacco ingredient release component also means that the materials can be released in a controlled manner because they will heat up and vaporize more quickly when the component is heated.

The surface area of the component for the release of tobacco components, and thus the release of tobacco components and other materials, can also be increased due to the presence of pores in the agglomerated structure. Such pores reduce the density of the agglomerated structure, improving heat transfer through the component to release the tobacco components.

In some embodiments, the pores may be formed by incorporating porous materials into the precursor composition. Selecting tobacco particles with a larger diameter and/or tobacco particles with a narrow particle size distribution can also improve the formation of small gaps or pores in the agglomerated structure. Alternatively or additionally, pores can be formed in the agglomerated structure after the formation of the agglomerated structure from the precursor composition, for example, by puncturing the structure or selectively removing part or parts of the agglomerated structure.

Thus, a combination of tobacco release component shape and porosity/density can be selected to control the surface area to volume ratio and/or to control the following: (a) heat transfer rate; (its) rate of aerosol formation; (iii) amount of formed aerosol; and (im) degree of release of tobacco components and other materials.

Components for the release of tobacco components according to the present invention contain at least one agent for the formation of an aerosol. It is known to use means for the formation of an aerosol to improve the taste impression of aerosols. The amount of aerosolizing agent that is incorporated into tobacco components or materials, such as those incorporated into tobacco heating products, is generally limited because aerosolizing agents are usually in liquid form and present on the surface of the tobacco material to which they are added. . As a result, in practice, the inclusion of more than about 10 95 by weight of the aerosolizing agent makes handling and handling of the material difficult.

However, as described in more detail below, embodiments of the present invention provide for the possibility of including a larger amount of agent for the formation of an aerosol. This provides greater variability in the selection of the amount of aerosolizing agent, and it can be used to control or regulate the release of tobacco ingredients and other materials from tobacco ingredient release components. Releasing an aerosolizing agent in aerosol form by heating (without burning) the component to release the tobacco ingredients not only improves the properties of the aerosol generated by the tobacco product into which the component is incorporated, but also improves the release of the tobacco ingredients and other materials from the component. This is especially true when the tobacco and/or agglomerated structure is impregnated with an aerosolizing agent.

The amount of aerosol generating agent also affects the rate of aerosol generation.

The means for generating an aerosol can be, for example, a means for generating an aerosol based on a polyol or a means for generating an aerosol not based on a polyol, preferably a means for generating an aerosol not based on a polyol. It can be a solid or a liquid at room temperature, but preferably it is a liquid at room temperature. Suitable polyols include sorbitol, glycerin and glycols such as propylene glycol or triethylene glycol. Suitable nonpolyols include monohydric alcohols, high boiling hydrocarbons, acids such as lactic acid, and esters such as diacetin, triacetin, triethyl citrate or isopropyl myristate. A combination of aerosolizing agents may be used in equal or different proportions. Particularly preferred are glycerol, propylene glycol, and glycerol triacetate (also known as triacetin).

According to the present invention, the release of tobacco components or other materials is not controlled by adjusting the pH of the tobacco and/or the precursor composition or component for releasing the tobacco components. Such pH adjustment may alter the nature of the ingredients and may not be desirable or regulatoryly acceptable for some products in some jurisdictions.

Tobacco particles

The tobacco particles present in the precursor composition are of a size small enough to permit the agglomeration of a plurality of such particles to form components for the release of tobacco constituents having the desired size for their intended use. Smaller tobacco particles have a higher surface area to volume ratio and may thus exhibit improved release of tobacco components compared to larger particles.

In addition, the size of the tobacco particles (and other particles in the precursor composition) affects the porosity and density of the agglomerated structures and components for the release of tobacco components. Thus, the size of tobacco particles can be selected to obtain a more porous agglomerated structure, which affects the release of tobacco components.

Thus, tobacco particle size is another factor that can be adjusted to influence the release of tobacco constituents.

Extrusion processes used to form agglomerated structures can be sensitive to particle size in the composition being extruded. Thus, it may be desirable that the particles in the precursor composition, including tobacco particles, have an average particle size of no more than about 0.5 mm, or have an average particle size of no more than about 0.3 mm when measured by sieving. In some embodiments, it may be desirable that the tobacco particles in the precursor composition have an average particle size of no more than about 0.5 mm, or have an average particle size of no more than about 0.3 mm when measured by sieving. In some embodiments, the average particle size is in the range of about 0.1 to about 0.4 mm, or in the range of about 0.2 to about 0.3 mm. In some embodiments, at least about 90 to 95 particles of the precursor composition have a particle size in the range of 0.1 to 0.5 mm. In some embodiments, at least about 90 to 95 tobacco particles of the precursor composition have a particle size in the range of 0.1 to 0.5 mm. In some embodiments, none of the particles in the precursor composition have a particle size greater than 1 mm.

Tobacco particles for inclusion in tobacco component release components can be formed by grinding, crushing, cutting or crushing the tobacco material. Suitable equipment for creating such tobacco particles includes, for example, shredders, cutters or mills such as hammer mills, roller mills or other types of commercially available grinding equipment.

Without being bound by any particular theory, it is believed that grinding tobacco to form tobacco particles enhances the release of tobacco components that include volatile flavoring materials and flavoring components, as well as nicotine. It is also believed that the increased surface area of tobacco particles facilitates evaporation. Smaller tobacco particles also improve the homogeneity of agglomerated structures formed from them together with other components.

The tobacco material used to form the tobacco particles can be any type of tobacco and any part of the tobacco plant, including the tobacco leaf blade, stem, petiole, leaf veins, pharmature and chips, or mixtures of two or more of these . Suitable tobacco materials include the following types: variety

Virginia or pipe-cured tobacco, Burley tobacco, Oriental tobacco, or blends of tobacco materials, optionally including those listed here. Tobacco can be expanded, for example, planted tobacco (IET), or processed by any other means. In some embodiments, the tobacco material may be a regenerated tobacco material. The tobacco may be pre-cured or untreated and may be, for example, whole stalks (55), chopped dried stalks (505), steam-treated stalks (515), or any combination thereof. The tobacco material may be fermented, dried, uncured, roasted or otherwise pre-processed.

Additional components of the predecessor composition

In some embodiments, the precursor composition comprises a diluent. The diluent can be in solid or liquid form. In some embodiments, the diluent is inert or substantially inert.

In some embodiments, the agglomerated structure formed from the precursor composition may have an increased surface area due to the inclusion of particles of inert filler material in the precursor composition. Suitable inert fillers may be porous or non-porous.

In some embodiments, the precursor composition does not contain a binding agent or binding additive. In other embodiments, the precursor composition contains a binding agent or a binding additive. The binding additive can be selected to promote the formation of an agglomerated structure, helping the tobacco particles to adhere to each other and to the other 60 components in the composition. Suitable binding additives include, for example, starches,

polysaccharides, pectins, celluloses, cellulose derivatives such as carboxymethylcellulose, and alginates.

In some embodiments, the tobacco component release components may contain a flavor modifier to modify the flavor properties provided by the tobacco particles or to add flavor properties. In some embodiments, a flavor modifier may be included in the precursor composition. Alternatively or additionally, a flavor modifier can be added to or applied to the agglomerated structure. Flavor modifiers include, for example, sauce materials, as well as "flavoring material" and "flavoring substance" that, where permitted by local regulations, may be used to create a desired flavor or aroma in a product for adult consumers. These may include extracts (eg licorice, hydrangea, Japanese white magnolia leaf, chamomile, fennel, cloves, menthol, Japanese mint, anise seed, cinnamon, allspice, wintergreen, cherry, berries, peach, apple, Drambuis liqueur , bourbon, Scotch whiskey, whiskey, spearmint, peppermint, lavender, cardamom, celery, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, cassia , cumin, cognac, jasmine, ylang-ylang, sage, fennel, allspice, ginger, anise, coriander, coffee or mint oil of any species of the genus Mepipa), flavor enhancers, blockers of bitter receptors, activators or stimulants of sensitive receptor sites, sugars and/or sugar substitutes (eg sucralose, acesulfame potassium, aspartame, saccharin, cyclamates, lactose, sucrose, glucose, fructose, sorbitol or mannitol) and other impurities such as charcoal, chlorophyll, minerals, plant substances or mouth fresheners. They can be artificial, synthetic or natural ingredients or their mixtures. They can be presented in any suitable form, for example, in the form of an oil, liquid, gel, wax or powder.

In some embodiments, the pH of the tobacco components to release the tobacco components is not adjustable. In particular, in some embodiments, the component does not have a basic pH, and/or the precursor composition does not have a basic pH. Additionally or alternatively, the composition-precursor preferably does not contain a means for adjusting the basic pH.

In some embodiments, water may be added to the precursor composition as a process additive. For example, the presence of water may facilitate the dissolution of components of the precursor composition, and/or it may facilitate binding or improve agglomeration.

Formation of agglomerated structures

In fig. 1 shows a block diagram showing the main steps of the methods according to the present invention. The tobacco raw material, which may be pre-conditioned or pre-treated, is provided in the form of particles having the desired particle size.

A precursor tobacco composition is formed that contains tobacco particles, at least one aerosolizing agent, and in some embodiments may contain additional components. These additional components can be in liquid form or in solid form.

Additional solid components are preferably in the form of particles or powder. In other embodiments, additional components can be introduced into the agglomerated structure separately from the precursor tobacco composition.

In some embodiments, water may be added to the precursor composition as a process additive. For example, the presence of water may facilitate the dissolution of components of the precursor composition, and/or it may facilitate binding or improve agglomeration.

Finally, an agglomerated structure is formed from the precursor composition, that is, a monolithic structure formed from a plurality of tobacco particles and other components of the precursor composition. In some embodiments, the agglomerated structure can be formed from the precursor composition by a process that includes one or more steps selected from the group consisting of granulation and/or extrusion, and optionally also spheronization.

Granulation of the composition-precursor includes binding or combining particles of the composition-precursor with each other to form larger objects consisting of a plurality of particles, referred to herein as agglomerated structures. Objects consisting of a plurality of particles formed by granulation are called granules, and they can have different geometric shapes, including, for example, the general shape of spheres, cylinders, etc.

In one embodiment, the granulation step used is wet granulation. In wet granulation, granules are formed by adding granulation liquid 60 to the powder layer. Mixing in the system, along with wetting the components in the composition-

precursor, leads to the aggregation of particles with the formation of wet granules. The granulation liquid can be at least partially removed by drying to provide dry granules. The granulating liquid can be water-based or solvent-based. Suitable granulation liquids include, for example, water, glycerin, ethanol and isopropanol, alone or in combination. In some embodiments, the granulation liquid contains an aerosolizing agent, such as glycerin or one of the other agents specified herein, and/or a binder or binding agent. In some embodiments, no water is added to the precursor composition to aid in granulation.

In another embodiment, the granulation step used is dry granulation. With dry granulation, granules are formed without the use of granulation liquid.

This type of process has the advantage that the precursor composition is not exposed to moisture and therefore there is no requirement to heat the granules to dry them. Granulation by dry granulation involves compression and densification of the precursor composition, usually under high pressure.

Extrusion of the precursor composition involves feeding the precursor composition through an orifice to form an extruded agglomerate. A process in which pressure is applied to the precursor composition in combination with shear forces results in agglomerated structures.

Extrusion can be performed using one of the main classes of extruders: screw, mesh and basket, roller and piston extruders. The formation of components for the release of tobacco components by means of extrusion has the advantage that this processing combines mixing, conditioning, homogenization and formation of the precursor composition.

In some embodiments, during extrusion, the free-flowing precursor composition is subjected to elevated pressure and temperature and forced through an orifice, such as a die, to form an extruded agglomerate. In some embodiments, the extruded agglomerate has an elongated shape and/or it can be cut into segments of a desired length as it exits the orifice. The rod-shaped extruded agglomerate can essentially be cut into segments of the desired length.

In some embodiments, the precursor composition comprising tobacco particles is subjected to temperatures of from about 40°C to about 150°C or from about 80°C to about 130°C in an extruder. The composition can be subjected to pressures ranging from about 2 bar up to about 100 bar or from about 5 bar to about 60 bar depending on the design of the head used.

In some embodiments, due to the relatively high density of the extruded agglomerate and the relatively open surface of the tobacco particles therein, the tobacco ingredient release components formed from the extruded agglomerate exhibit adequate heat and mass transfer, which has a positive effect on the release of tobacco ingredients such as flavoring materials and nicotine

In some embodiments, extrusion may be a generally dry process in which the precursor composition is a substantially dry material that contains tobacco particles and optionally other particulate materials, including, for example, base, diluent, solids flavor and aroma modifiers, etc.

In some embodiments, liquids may be added to the precursor composition during the extrusion process. For example, water can be added to the composition-precursor, for example, as a process additive to promote dissolution or solubilization of the components of the composition or to promote binding or agglomeration. Alternatively or additionally, a humectant may be added to the precursor composition.

In some embodiments, the liquid may be an aerosol forming agent such as glycerin or other substances described herein. When a liquid is added to the precursor composition in this way, not only is the liquid applied to the surface, but the extruded agglomerate is impregnated with the liquid as a result of the action of the extruder pressure combined with intense mixing with high shear forces. If the liquid is an aerosolizing agent, this may result in a high availability of the aerosolizing agent in the agglomerated product to improve the evaporation of flavor components from the tobacco particles and other components of the agglomerated structure, which improves the release of tobacco components from the resulting extruded components to release tobacco components

In some embodiments, due to impregnation of the extruded agglomerate 60 with an aerosolizing agent, larger volumes of the agent may be included in the tobacco release component than if the aerosolizing agent were simply applied to the surface of the precursor composition or extruded agglomerate. In some embodiments, the amount of aerosolizing agent included in the tobacco release component can be at least about 3 95 by weight, at least about 4 95, 5 95, 6 9, 7 Uo, 8 Uo, 9 Uo, 10 U, 11 95, 12 95, 13 B, 14 95, 15 B, 16 b, 17 95, 18 95, 19 95 by weight or at least about 20 95 by weight. In some embodiments, the amount of aerosolizing agent included in the tobacco ingredient release component can be up to about 15 95, up to about 16 95, 17 95, 18 95, 19 95, 20 95, 21 95, 22 905, 23 Uu , 24 Uyu, 25 Uyu, 26 95, 27 U, 28 90, 29 95 by weight or up to approx.

ZO 9o by weight.

In some embodiments, the one or more aerosol forming agents are provided in an amount of from about C 95 to about 30 95 by weight of the component, preferably in an amount of from about 15 95 to about 30 95 by weight of the component.

Extruded agglomerate is formed using a hole or head through which it is forced to move. In some embodiments, the extruded agglomerate is cut into pieces of desired length. Parts formed in this way can be used as components for the release of tobacco components, or they can be subjected to further processing.

In some embodiments, the orifice or head is shaped to provide a continuous bundle of extruded agglomerate. For example, the extruded agglomerate may have the form of a solid cylindrical rod. Alternatively, the extruded agglomerate may have various cross-sectional shapes, including oval, polygonal (eg, triangular, square, etc.) and star-shaped.

In some embodiments, the extruded composition is provided with a desired shape selected to enhance or facilitate the release of the flavoring material, for example, by providing a shape that has a large surface area per unit volume. This large surface area can be provided on the outer surface of the extruded agglomerate, for example, by choosing cross-sectional shapes with a larger perimeter. Alternatively or additionally, a large surface area can be provided by creating channels in the extruded agglomerate.

In some embodiments, the orifice or head is shaped to provide an extruded agglomerate with internal channels. These internal channels provide additional surface area and can improve the release of tobacco components.

Examples of some nozzle or head designs are shown in Fig. 2a, 25 and 2s. These nozzles or heads have holes 21 through which the extruded composition is forced to form an extruded agglomerate with a structure similar to a spoked wheel. These nozzles or heads are used in the extruder as shown in fig. 24 and 2e, in which the direction of the flow of the extruded material is indicated by arrow A.

In fig. C shows an image of several extruded agglomerates, and different geometric cross-sectional shapes are shown, which contain internal channels. Some of these extruded agglomerates are formed using the nozzle designs shown in FIG. 2a, 25 and 2s.

Tobacco component release components formed from extruded agglomerates with cross-sections of this shape have an internal channel structure that has primarily adjustable bundle ventilation properties and a significantly increased internal surface area leading to improved heat transfer and mass transfer. As a result, such components demonstrate a better, more uniform release of flavor material due to evaporation.

In addition, the structure with internal channels shows significantly increased strength in both radial and axial directions, which is advantageous for further processing of the extruded agglomerate, for example, when it is cut into segments.

In some embodiments, the diameter of the component for releasing tobacco ingredients is from about 4 mm to about 10 mm, or the diameter can be from about 5 mm to about 8 mm.

In some embodiments, the component for releasing tobacco components is a cylindrical tobacco segment. In some embodiments, the cylinder has a diameter of about 5 mm to about 8 mm and a length of about 5 mm to about 80 mm, about 15 mm to about 50 mm, or about 20 mm to about 30 mm.

Using different nozzle designs and/or different process parameters in the extruder, including temperature, pressure and shear force, extruded agglomerates with 60 different physical properties can be produced, including different heat transfer properties, tensile strength,

and are capable of forming different aerosols and/or modifying aerosols that are entrained through the extruded agglomerate.

The composition of the precursor composition can also play a very important role in determining the physical and mechanical properties of the extruded material and, consequently, the components for the release of tobacco components.

In some embodiments, the extruded agglomerate is given a specific shape after exiting the extruder. In some embodiments, the extruded agglomerate is cut to an initial length, such as 1 meter, and allowed to cool before being cut into sections of the desired length to provide components for releasing the tobacco ingredients of the desired sizes.

In some embodiments, the extruded agglomerate may be cooled immediately prior to or immediately upon exiting the extruder. In some embodiments, the cooling is intensive and includes subjecting the extruded agglomerate, which is at an elevated temperature, for example, from about 30°C to about 100°C, or from about 40°C to about 70°C, to a cooling agent that lowers the temperature to a range of from about 0 "C to about 25 "C, or from 5 "C to about 15 "C. Such rapid cooling of the extruded agglomerate can improve the internal and external stability of the extruded agglomerate. In some embodiments, the head is cooled to achieve this effect.

In some embodiments, it may be desirable to control the temperature of the precursor composition during extrusion, including before feeding the composition through the head. This is especially true when the precursor composition contains temperature-sensitive components such as aerosolizing agents such as glycerin. Thus, in some embodiments, extruding the precursor composition includes reducing the temperature of the precursor composition before it reaches the die. Such cooling of the precursor composition can lead to the formation of an extruded agglomerate with superior properties or can improve the process of forming a bundle, for example, if channels are to be formed in a bundle of extruded agglomerate.

In some embodiments, the precursor composition may be granulated prior to extrusion. If the precursor composition contains several different types of particles, this granulation step can improve homogenization in the extruded agglomerate. The granulated precursor composition can be fed into an extruder to form components to release the tobacco ingredients.

Granulation of the composition-precursor includes binding or combining particles of the composition-precursor with each other to form larger objects consisting of a plurality of particles that are agglomerated structures. Objects consisting of a plurality of particles formed by granulation are called granules, and they can have different geometric shapes, including, for example, the general shape of spheres, cylinders, etc.

In one embodiment, the granulation step used is wet granulation. In wet granulation, granules are formed by adding granulation liquid to the powder layer. Mixing in the system, together with wetting of the components in the precursor composition, leads to the aggregation of particles with the formation of wet granules. The granulation liquid can be at least partially removed by drying to provide dry granules. The granulating liquid can be water-based or solvent-based. Suitable granulation liquids include, for example, water, ethanol and isopropanol, either alone or in combination. In some embodiments, the granulation liquid contains an aerosolizing agent, such as glycerin.

In another embodiment, the granulation step used is dry granulation. With dry granulation, granules are formed without the use of granulation liquid.

This type of process has the advantage that the precursor composition is not exposed to moisture and therefore there is no requirement to heat the granules to dry them. Granulation by dry granulation involves compression and densification of the precursor composition, usually under high pressure.

In some embodiments, spheronization is used to further process the extruded segments. These segments are generally cylindrical in shape and are cut or torn into equal lengths after extrusion. Then they are gradually given spherical shapes by means of spheronization. This shaping occurs as a result of plastic deformation, and spheronization can result in spherical agglomerated structures, often with approximately the same diameter. for

In some embodiments, if multiple tobacco component release components are included in the filter, it may be in a "Dalmatian" filter section where the tobacco component release components are distributed throughout the fibrous material of the filter rod. Alternatively, components for releasing tobacco ingredients can be placed in a cavity in the filter. The cavity may, for example, be a hollow section located between two (or more) adjacent filter rods, or the cavity may be a nest formed in the filter rod. In such embodiments, the tobacco release components may be small in size, such as in the form of granules.

In other embodiments, one larger component for releasing tobacco components is included in the filter. For example, one component for the release of tobacco components can be embedded in the fibrous material of the filter rod.

Alternatively, the tobacco component release component may be included in a multi-segment filter, with the tobacco component release component 60 itself forming one of the filter segments. In such embodiments, the component for releasing tobacco ingredients can be of any shape or size, but it may be preferred if the component has a cylindrical shape and dimensions similar to or compatible with the shape and dimensions of the filter segments. In some embodiments, the component for releasing tobacco ingredients may be surrounded by a filter material, such as a layer of fibrous filter tow, to form a filter segment. In other embodiments, the component for releasing tobacco components may have the dimensions of a filter rod, and it may be included in a filter with one or more adjacent filter rods. Alternatively, a component for releasing tobacco components can be included in a hollow section located between two (or more) adjacent filter rods.

In some embodiments, the tobacco ingredient release component itself can be a filter element in the aerosol delivery device, and it can filter out condensates and other suspended particles in the aerosol before the user inhales the aerosol.

According to some embodiments, one or more tobacco component release components are included in an aerosol delivery device or a smoking material heating device for vaporizing the at least one smoking material component in which the tobacco segment is heated without burning (i.e., a tobacco heating product or so-called non-combustion heating product).

In some of these products, the tobacco segment is heated to generate an aerosol.

One option is to include one or more components to release tobacco components in the filter of such products. In some embodiments, multiple tobacco component release components are included in the tobacco heating product filter. In other embodiments, one component for releasing tobacco components is included in the filter of the tobacco heating product.

Another option involves the inclusion of one or more components for the release of tobacco components in the tobacco segment of such products. In some embodiments, one or more tobacco component release components may be incorporated into the tobacco material to form a tobacco segment. For example, one or more tobacco component release components can be distributed in the tobacco material, such as cut tobacco or reconstituted tobacco, to contribute to the flavoring properties provided by the tobacco. In other embodiments, the tobacco included in the tobacco segment of the tobacco heating product consists of or essentially consists of one or more components to release tobacco constituents. In one embodiment, the tobacco segment heated by the tobacco heating product consists of, or essentially consists of, one or more components for releasing tobacco constituents. The tobacco release component can be heated directly. If the tobacco segment is several components for the release of tobacco components, they can be contained in a container or cartridge. At least portions of the container or cartridge may be air permeable to allow air to flow over or through the components to release the tobacco ingredients.

In fig. 6 shows a cross-sectional view of an example of a tobacco heating product for heating smoking material. The device 11 has a heating chamber 14 which, during use, contains smoking material to be heated and vaporized. In this embodiment, the smokable material is in the form of a monolithic component 13 for the release of tobacco components. However, the smokable material may be several components for releasing the tobacco ingredients contained in a heating chamber or provided in such a cartridge, as illustrated in FIG. 8.

Device 11, shown in fig. 6, additionally has an electronics/power chamber 16, which may, for example, contain control circuitry and/or a power source (not shown).

The electrical control circuit may include a controller, such as a microprocessor device, configured and adapted to control the heating of the smokable material by means of a heating element (not shown). The in-use control circuitry may receive a signal from, for example, a puff-activated sensor that is sensitive to, for example, changes in pressure or changes in air flow rate that occur when the user initiates a puff through the device 11. Control circuitry can then function to provide heating of smoking material "on demand". Various designs are available for a puff-activated sensor, including, for example, a thermistor-based sensor, an electromechanical device, a mechanical device, an optical device, an optomechanical device, and microelectromechanical systems (MEM5). Alternatively, the device may have a manually operated switch by which the user initiates the puff.

The heating chamber 14 is contained within the housing 12. Support and/or insulating means (not shown) may be provided between the heating chamber 14 and the housing 12, for example to help thermally insulate the housing 12 from the heating chamber 14 so that the housing 12 does not become hot. or at least too hot to touch during use.

The housing 12 contains an inlet 15 through which air is drawn into the device. The housing 12 also includes an outlet opening 17 on the mouthpiece 18 of the device 11. Air is drawn into the device 11 through the inlet port 15, passes through the device capturing the tobacco components released by the tobacco component release component 13, and the resulting aerosol generated by the device 11 exits from the device 11 through the outlet 19 and inhaled by the user.

In some embodiments, one or more components for releasing tobacco ingredients are included in the so-called hybrid product for heating the smokable material to vaporize at least one component of the smokable material. In some of these products, the tobacco segment is heated to generate an aerosol, in addition to heating a liquid, such as a liquid that contains nicotine or a liquid that does not contain nicotine, that is heated by a heat source to generate an aerosol or vapor. In some hybrid products, the aerosol or vapor generated from the liquid is drawn from above or through the tobacco segment, capturing the tobacco flavoring materials. In other embodiments, the aerosol or vapor generated from the liquid is not drawn in from above or through the tobacco segment.

In hybrid products that contain a filter, one option is to include components to release tobacco components in the filter of such products, in a manner similar to that described for tobacco heating products. In some embodiments, multiple tobacco release components are included in the hybrid product filter. In other embodiments, one component for the release of tobacco components is included in the filter of the hybrid product.

If the smoking product is a so-called hybrid product, another option involves the inclusion of components for the release of tobacco components in the tobacco segment of such products. In some embodiments, one or more tobacco component release components may be incorporated into the tobacco material to form a tobacco segment. For example, one or more tobacco component release components can be distributed in the tobacco material, such as cut tobacco or reconstituted tobacco, to contribute to the flavoring properties provided by the tobacco. In other embodiments, the tobacco included in the tobacco segment of the hybrid product consists of one or more components to release tobacco constituents. In one embodiment, the tobacco segment in the hybrid product consists or essentially consists of one or more components to release tobacco constituents.

In fig. 7 shows a cross-sectional view of an example of a hybrid product for heating a smoking material and a liquid. The device 21 has a housing 22 which contains a chamber 24 which, in use, contains a smokable material to be heated and vaporized. In this embodiment, the smokable material is in the form of a monolithic component 23 for the release of tobacco components. However, the smokable material may be multiple components for releasing the tobacco ingredients contained in a chamber or provided in such a cartridge as illustrated in FIG. 8. The housing 22 also includes a liquid reservoir 25 which contains a liquid 26 to be heated to vaporize.

The device 21 additionally has an electronics/power chamber 27, which may, for example, contain electrical control circuitry and/or a power source (not shown). The electrical control circuit may include a controller, such as a microprocessor device, configured and adapted to control the heating of the smokable material and liquid 26 by means of one or more heating elements (not shown). The electrical control circuit may provide the ability to activate the device 21 from a puff to provide heating of smokable material "on demand". Alternatively, the device 22 may have a manually operated switch by which the user initiates a puff.

The housing 22 also includes an inlet 28 through which air is drawn into the device. The housing 22 also includes an outlet 29 on the mouthpiece 30 of the device 21. Air is drawn into the device 21 through the inlet 28, passes through the device, capturing the vapor created 60 by heating the liquid 26 in the liquid tank 25 and the tobacco components released by the component 23 for release of tobacco components, and the resulting aerosol generated by the device 21 exits the device 21 through the outlet 29 and is inhaled by the user.

Hybrid device 21, schematically shown in fig. 7, represents only one possible configuration of such a device. The relative positions of the liquid reservoir 25 and the smokable material chamber 24 can be changed, as can the path of the air flowing through the device.

In one embodiment, the liquid reservoir is located upstream of the smokable material to be vaporized. Alternatively, the liquid reservoir may be located downstream of the smokable material to be vaporized. In yet another arrangement, the two aerosol sources in the device may be side-by-side, etc.

In some embodiments, the vapor generated by heating the liquid in the liquid reservoir flows over or through a smokable material that contains or consists of one or more tobacco release components. In some embodiments, the increased temperature of the steam results in the release of tobacco components. Alternatively or additionally, the smokable material may be heated separately by means of a heating means.

In some embodiments, a hybrid device is provided in which the vapor generated by heating the liquid heats the smokable material to vaporize at least one component of the smokable material. In some embodiments, the liquid is a liquid that does not contain nicotine. In other embodiments, the liquid contains nicotine. If the smokable material is heated by steam to vaporize at least one component of the smokable material, in certain embodiments, the device does not include a separate means for heating the smokable material. The smokable material may contain or consist of at least one tobacco release component.

In other embodiments, the vapor generated by heating the liquid in the liquid reservoir does not flow over or through a smokable material that contains or consists of one or more tobacco release components. Rather, this vapor and the aerosol generated by heating the smokable material only mix after both are formed.

The tobacco heating products and hybrid products described herein may, in some embodiments, contain tobacco segments in the form of containers or cartridges containing one or more tobacco component release components. These containers or cartridges can be removed. They can replace both the chamber holding the smokable material and the smokable material in the device described above with reference to fig. 6 and 7, as well as in the alternative embodiments described.

In fig. 8 shows a cartridge 31 for a tobacco segment that includes a housing 32 defining a cavity in which one or more tobacco release components of the present invention are held (not shown). The housing 32 may, for example, be made of molded plastic or similar material. In order to ensure the passage of air drawn through the device into the cartridge 31 and above or through one or more components for the release of tobacco components, as well as its exit from the cartridge Z1, the housing 32 of the cartridge 31 is provided with ventilation holes 33. In some embodiments, the cartridge 31 may further comprise a heating means which may be heated by a suitable means for heating one or more components to release the tobacco constituents contained therein.

In some embodiments, one or more tobacco release components are included in a filter or filter element for inclusion in a combustible smoking product.

In the context of this document, the term "combustible smoking product" includes products suitable for smoking, such as cigarettes, cigars and cigarillos based on any of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes. Combustible smoking products include a rod of smokable material and a filter that includes at least one filter element.

In the context of this document, the term "vaping smoking product" does not include heatless (HNV) products or other nicotine delivery products, such as aerosol generating devices, which include electronic cigarettes or hybrid products. 60 The component for releasing tobacco components can be located in the filter or in the filter element forming the filter of the combustible smoking product, as a result of which the released tobacco components are captured in the aerosol generated by the smoking product during use, modifying the properties of the aerosol, for example, due to the transfer of tobacco components , including tobacco flavoring material, into this aerosol.

Filters and filter elements suitable for use in combustible smoking products contain filter material to remove certain smoke constituents from the smoke inhaled through the smoking product during use. The filter material is collected to form a rod, which is cut to form individual filter segments.

A filter for a smoking product can be made of one segment of a filter rod, or it can be made of several filter elements, with or without a cavity or gaps between them. A widely used filter material is a continuous tow of fibrous cellulose acetate plasticized with triacetin.

Other filter materials may include at least one material selected from polyvinyl alcohol (PMON), polylactic acid (PI A), poly(ε-caprolactone) (PCI), poly(1-4-butanediol succinate) (PB5), butylene adipate copolymer and terephthalate (PET), starch-based materials, paper, aliphatic polyester materials, and polysaccharide polymers, or a combination thereof.

The filter may be cylindrical in shape and generally have a length and overall circumference appropriate to the type of combustible smoking product in which it is used. Smoking products such as cigarettes and their formats are often referred to according to the length of the cigarette: "regular" (typically in the 68-75mm range, e.g. from about 68mm to about 72mm), "short" or "mini" (68mm or less), "large" (typically in the range of 75-91 mm, such as from about 79 mm to about 88 mm), "long or "extra large" (typically in the range of 91-105 mm, such as from about 94 mm to about 101 mm) and "ultra-long" (typically ranging from about 110 mm to about 121 mm).

They are also called according to the circumference of the cigarette: "regular" (about 23-25 mm), "wide" (more than 25 mm), "thin" (about 22-23 mm), "semi-thin" (about 19-22 mm) , "ultra-thin" (about 16-19 mm) and "micro-thin" (less than about 16 mm). Accordingly, a cigarette in a large ultra-thin format will, for example, have a length of approximately 83 mm and a circumference of approximately 17 mm. Regular large format cigarettes have a circumference of 23 to 25 mm and a total length of 75 to 91 mm.

Each format can be made with filters of different length values, with smaller filters generally used in formats with smaller length values and circumferences. Typically, the length of the filter will be from 15 mm in short conventional formats to 30 mm in ultra-long ultra-thin formats. The lining paper will be longer than the filter, for example, 3-10 mm longer.

The components for the release of tobacco components according to the present invention, located in the filter of the combustible smoking product, are not exposed to significant temperature increases during the use of the smoking product. However, the temperature in the filter of a regular cigarette gradually rises during use. In a conventional combustible smoking product, such as a cigarette, and under normal smoking conditions, such as the I5O smoking mode, smoking may involve 8-9 puffs, with the first 5-6 puffs accompanied by only slight increases in temperature during puffs. For example, the first puffs may be accompanied by a temporary increase in temperature of the order of 1-5 "C, and the temperature remains in the range from 20 to 30 "C, and in some cases from 23 to 26 "C. During the final few puffs of a conventional combustible smoking product, such like a cigarette, the temperature begins to rise more during puffs, with peak values starting to exceed 30 "C and exceeding 60 "C for the penultimate and last puffs.

This change in temperature can be used to initiate or facilitate the release of materials from the component to release the tobacco ingredients during use of the smoking article. For example, an increase in temperature can help vaporize the remaining components that were not released during the first few puffs. Alternatively or additionally, materials may be included in the component to release the tobacco ingredients, in particular, to release or enhance the release of the tobacco ingredients at such elevated temperatures.

In some embodiments, multiple tobacco release components are included in a filter element for a combustible smoking product. In other embodiments, one component for releasing tobacco components is included in the filter element. 60 If multiple tobacco release components are included in the filter, it may be in a "Dalmatian" filter section where the tobacco release components are distributed throughout the fibrous material of the filter rod.

Such a layout is shown in fig. 9. As shown in fig. 9, the smoking article 21 includes a filter 22 and a cylindrical rod 23 of smokable material, such as tobacco, aligned with the filter 22, whereby one end of the rod 23 of smokable material adjoins the end of the filter 22. The filter 22 is wrapped with fissile (not shown). , and a rod 23 of smokable material is attached to the filter 22 with rimmed paper in the usual manner. The filter 22 is essentially cylindrical and contains a filter material 24 in which the components 25 are distributed for the release of tobacco components.

Alternatively, components for releasing tobacco ingredients can be placed in a cavity in the filter. The cavity may, for example, be a hollow section located between two (or more) adjacent filter rods, or the cavity may be a nest formed in the filter rod. In such embodiments, the tobacco release components may be small in size, such as in the form of granules.

In other embodiments, larger monolithic components for releasing tobacco components are included in the filter. For example, one component for the release of tobacco components can be embedded in the fibrous material of the filter rod.

Such a layout is shown in fig. 10, which shows a smoking product 21 that includes a filter 22 and a cylindrical rod 23 of smokable material, the filter 22 containing a component 26 for releasing tobacco components, which is surrounded by a filter material 24.

Alternatively, the component for releasing tobacco components can be included in a multi-segment filter, and the component for releasing tobacco components itself forms one of the segments of the filter. In such embodiments, the component for releasing tobacco ingredients can be of any shape or size, but it may be preferred if the component has a cylindrical shape and dimensions similar to or compatible with the shape and dimensions of the filter segments. In some embodiments, the component for releasing tobacco ingredients may be surrounded by a filter material, such as a layer of fibrous filter tow, to form a filter segment. In other embodiments, the component for releasing tobacco components may have the dimensions of a filter rod, and it may be included in a filter with one or more adjacent filter rods. Alternatively, a component for releasing tobacco components can be included in a hollow section located between two (or more) adjacent filter rods.

As shown in fig. 11, the smoking product 21 contains a filter 22 and a cylindrical rod 23 of smoking material, and the filter 22 is made of several filter segments.

A filter segment 27 is provided, located at the end of the filter, which is brought to the mouth, and a filter segment 28 is located at the end of the tobacco rod of the filter. Between these filter segments is a component 26 for releasing tobacco components, which contains filter material 24.

Filters and filter elements according to the present invention may, in some embodiments, additionally contain additives. For example, the additive can be particles of adsorbent material, including, for example, activated carbon, an ion exchange resin such as SK20, zeolite, silica gel, meerschaum, aluminum oxide (activated or not), carboxyl cationite, magnesium silicate, including sepiolite ( Mad«5ivbO15(OH)2:6bHgO) and their combinations.

If the smoking product filter contains an adsorbent, in some embodiments, the component for releasing the tobacco components is located downstream of the adsorbent.
