[Diagram 2] FIG. 1 is a schematic cross-sectional view of a non-combustion aerosol delivery device for generating aerosol from a permeable container holding a dried extract from plant material. [Diagram 3] FIG. 1 is a schematic cross-sectional view of a hybrid device for generating aerosol from a permeable container holding a dry extract from plant material and an additional vapor source. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0040] The present invention relates to articles of manufacture that include a permeable container that holds a dried or dehydrated fragrance and / or active delivery composition formed from extracts derived from fragrance-containing and / or active-containing plant material.

[0041] In some embodiments, the extract is a liquid solution or suspension and may be dried or dehydrated using processes such as spray drying or freeze drying. Dried or dehydrated perfume and / or active delivery compositions may be formed from precursor materials including extracts from perfume- and / or active-containing botanical materials and aerosol-forming materials.

[0042] The perfume and / or active delivery composition, which comprises a dry extract from perfume-containing and / or active-containing plant material, contains a high concentration of perfume and / or active, with little or no material that does not contribute to the aerosol generated from the dry aerosol-generating material. Thus, a very small amount of the perfume and / or active delivery composition is sufficient to deliver the desired active and perfume content. Moreover, the perfume and / or active can be released by the composition quickly and efficiently.

[0043] In some embodiments, the dry aerosol forming material has a moisture content of 0 to about 10%, or 0 to about 5%, (calculated on a wet weight basis) as measured by gas chromatography-thermal conductivity detector (GC-TCD) or Karl Fischer titration. In some embodiments, the moisture content of the dry aerosol forming material is less than about 3% by weight, e.g., about 0 to about 3% by weight, or about 0.5 to about 2.5% by weight.

[0044] Karl Fischer titration is a classical method of chemical analysis to reliably determine the amount, even trace amounts, of water in a sample. The method can be easily performed using an automated Karl Fischer titrator. Similarly, the use of GC-TCD is also an established method to reliably determine the water content in a sample.

[0045] Unless otherwise stated, references to water content herein are references to water content as measured by Karl Fischer titration.

[0046] In the present disclosure, a product is provided that includes a permeable container that contains a fragrance and / or active delivery composition. The container allows exposure of the fragrance and / or active delivery composition to airflow and moisture. The container also allows the flavor and / or active ingredients released by the composition to exit the container and be delivered to a user.

[0047] In some embodiments, packaging a portion of the perfume and / or active delivery composition in a permeable container is carried out in a controlled low humidity environment to minimize the moisture absorbed by the perfume and / or active delivery composition.This is because this hygroscopic material may become more difficult to handle and process when it absorbs moisture and becomes more sticky.In some embodiments, the perfume and / or active delivery composition does not need to be protected from moisture after being packaged in a container, since the absorption of moisture is not as detrimental after entering the container and may even be beneficial in some embodiments discussed herein.

[0048] Thus, there is provided a permeable container comprising a perfume and / or active delivery composition comprising dried precursor material comprising an extract from perfume- and / or active-containing plant material.

[0049] In some embodiments, the hygroscopic perfume and / or active delivery composition has a moisture content of about 10% or less or about 5% or less (calculated on a wet weight basis) as measured by gas chromatography-thermal conductivity detector (GC-TCD) or Karl Fischer titration. This moisture content is stable, meaning that the moisture content of the perfume and / or active delivery composition is within this range not only when it is first prepared, but also after it is incorporated into an article, and after transportation and storage. Even under "normal" humidity conditions, this stable moisture content is observed despite the fact that the hygroscopic perfume and / or active delivery composition absorbs moisture rapidly when exposed to the environment. In fact, when a perfume and / or active delivery composition is described as hygroscopic, this means that it rapidly absorbs water from the surrounding environment, greatly increasing its moisture content. For example, when the fragrance and / or active delivery composition is exposed to the environment (e.g., upon storage in an open container, etc.), the moisture content increases rapidly to greater than 20% or even 25% (calculated on a wet weight basis) as measured by gas chromatography-thermal conductivity detector (GC-TCD) or Karl Fischer titration.

[0050] permeable container The permeable containers disclosed herein provide a moisture and air permeable barrier around the perfume and / or active delivery compositions formed by drying extracts from perfume- and / or active-containing plant materials. The permeable containers may provide precise doses or amounts of the perfume and / or active delivery compositions.

[0051] The permeable container may be rigid or non-rigid. In some embodiments, the permeable container is a wrapper, bag, or pouch. In other embodiments, the container may be a pod, capsule, or cartridge.

[0052] The wrapper, bag or pouch may be flexible, for example, formed from one or more sheets. Once a portion of the perfume and / or active delivery composition has been added, the sheets may be joined together to seal the wrapper, bag or pouch. The wrapper, bag or pouch forms a chamber within which the perfume and / or active delivery composition is sealed.

[0053] In some embodiments, the sheet is formed or consists of a moisture impermeable material, such as a polymer sheet, metal foil or laminate sheet, which is perforated to make it moisture permeable, hi other embodiments, the sheet material comprises a permeable or porous material, such as a porous paper, fabric or fleece.

[0054] In some embodiments, the sheet comprises a woven or nonwoven fabric or fleece comprising a plurality of fibers, hi some embodiments, the fleece or fabric is made by a dry laid, air laid, wet laid, spun melt, melt blown, or the like process to entangle fibers or filaments into a web in a manner that does not involve weaving or knitting.

[0055] The fabric may include fibers formed from materials including cellulose fibers, viscose fibers, regenerated cellulose fibers, wood fibers, cotton fibers, wool fibers, or other fleece-forming polymers, such as polyglycolic acid fibers, polylactic acid fibers, polyhydroxyalkanoate fibers, polycaprolactone fibers, polybutylene succinate fibers, polybutylene succinate adipate fibers, and combinations thereof. In some embodiments, the fibers are heat stable and / or biodegradable.

[0056] The pouches may be provided as a single pouch or as a series of connected pouches, each pouch holding a perfume and / or active delivery composition. The multiple pouches may all hold the same perfume and / or active delivery composition, or two or more different perfume and / or active delivery compositions. The series of connected pouches may be configured to allow a single pouch to be separated from the rest and used. Alternatively, in some embodiments, the series of pouches may remain connected and may be used sequentially.

[0057] An example of a permeable pouch is shown in Figure 1. The pouch 1 comprises two sheets 2 of porous material that are fused or glued along their edges to form a chamber in which the perfume and / or active delivery composition 3 is sealed.

[0058] In some embodiments, the dried perfume and / or active delivery composition is placed into an already formed container. In other embodiments, the perfume and / or active delivery composition is added as the container is being formed. This may be an attractive option when the container is a bag or pouch.

[0059] In further embodiments, the precursor material can be added to a container and then dried in the container to form the perfume and / or active delivery composition. This option can be attractive when the container, such as a pod, capsule or cartridge, is rigid and therefore suitable for holding a liquid or slurry. The material of the container must also be compatible with the drying process used to dry the precursor. In some embodiments, the precursor material can be frozen before being added to the container or while in the container, for example by quick freezing by exposure to liquid nitrogen. The frozen precursor is then dried to form the perfume and / or active delivery composition.

[0060] Fragrance and / or Active Delivery Compositions The perfume and / or active delivery composition comprises a dried extract derived from perfume- and / or active-containing plant material.

[0061] In some embodiments, the fragrance and / or active delivery composition is formed by drying a precursor material that includes an extract from a fragrance-containing and / or active-containing plant material. The drying process is selected to preserve the desired components of the precursor material, and thus the fragrance and / or active delivery material may include one or more actives and / or fragrances.

[0062] In some embodiments, the extract from the perfume-containing or active-containing plant material is an extract obtained by contacting the plant material with a suitable solvent, such as an aqueous solvent or an alcohol, such as ethanol, and the liquid portion containing the solvent and any dissolved plant components is then separated or partially separated from the remaining solid plant material to provide the extract contained in the precursor composition, which can then be dried.

[0063] The precursor material may also optionally include one or more other functional materials. Additionally or alternatively, one or more functional materials may be added to the dry precursor material to provide a fragrance and / or active delivery material with desired ingredients and properties.

[0064] At least some embodiments of the present invention take advantage of flavor and / or active delivery compositions that have a long shelf life and can be easily transported and stored. Without wishing to be bound by any particular theory, it is hypothesized that the low water content of the flavor and / or active delivery composition reduces the evaporation of other solvents over time, reducing the degradation of actives such as nicotine, flavors and / or other volatile compounds.

[0065] Low moisture content also inhibits microbial growth. In some embodiments, the compositions may be stored at temperatures ranging from 0 to 35° C. In some embodiments, the compositions may be stored at up to about 30%, or even 50% relative humidity prior to use.

[0066] The fragrance and / or active delivery compositions may also have the advantage of having a high concentration of the desired ingredient, meaning that a relatively small amount of the composition is needed and the desired ingredient is quickly and easily released upon use.

[0067] In some embodiments, the extract from flavor-containing or active-containing plant material is an extract from tobacco material. Importantly, in such embodiments, the composition provides a reasonable intensity of authentic tobacco taste.

[0068] The tobacco extract or material may be from or may be any type of tobacco and any part of the tobacco plant, including tobacco blades, stems, stalks, ribs, crumbs and bits, or a mixture of two or more thereof. Suitable tobacco extracts or materials include the following types: Virginia or flue-cured tobacco, Burley tobacco, Oriental tobacco, or blends of tobacco materials, optionally including those listed herein. Tobacco, such as dry ice expanded tobacco (DIET), may be expanded or processed by any other means. In some embodiments, the tobacco material may be a reconstituted tobacco material. The tobacco may be pre-processed or unprocessed, for example, solid stem (SS), shredded dried stem (SDS), steam treated stem (STS), or any combination thereof. The tobacco material may be fermented, cured, uncured, roasted, or otherwise pre-processed. The tobacco material may be provided in the form of cut rag tobacco. The cut rag tobacco may have a cut width of at least 15 cuts / inch (about 5.9 cuts / cm, which corresponds to a cut width of about 1.7 mm). Cut rag tobacco can be formed from a mixture of tobacco material forms, such as a mixture of one or more of reconstituted tobacco, leaf tobacco, extruded tobacco, and band-cast tobacco.

[0069] The precursor material that is dried to form the flavor and / or active delivery composition may comprise at least about 10%, at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, or at least about 40% by weight of tobacco solids (calculated on a wet weight basis).

In some embodiments, the precursor material comprises between about 20% and about 40% by weight of tobacco solids (calculated on a wet weight basis).

[0070] In some embodiments, the precursor material comprises at least about 10% by weight, at least about 20% by weight, at least about 30% by weight, at least about 40% by weight, at least about 50% by weight, at least about 60% by weight, at least about 70% by weight, at least about 80% by weight, or at least about 90% by weight of an extract derived from tobacco or other flavor- or active-containing plant material (calculated on a wet weight basis). Alternatively or additionally, the precursor material may comprise up to about 99% by weight, up to about 90% by weight, up to about 80% by weight, up to about 70% by weight, or up to about 60% by weight of an extract derived from tobacco or other flavor- or active-containing plant material (calculated on a wet weight basis). In some embodiments, the precursor material comprises about 50% by weight of a tobacco extract (calculated on a wet weight basis).

[0071] In some embodiments, the aerosol-forming material may comprise at least about 45%, at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, or at least about 95% by weight of tobacco material or tobacco extract, or flavorant- or active-containing plant material extract (calculated on a dry weight basis). In some embodiments, the aerosol-forming material may comprise from about 60 to about 80% by weight of tobacco extract (calculated on a dry weight basis).

[0072] In some embodiments, the dry flavor and / or active delivery composition may contain from about 2% to about 10% by weight of nicotine, or from about 3% to about 6% by weight of nicotine (calculated on a dry weight basis).

[0073] In some embodiments, the precursor material comprises about 50% v / v tobacco extract. When the precursor material comprises about 50% v / v tobacco extract, and the tobacco extract has a tobacco solids content of about 55 to about 60% v / v, the overall tobacco solids content of the precursor material is about 27.5 to about 30% v / v.

[0074] In some embodiments, the tobacco extract has a solids content of about 40% to about 65%, about 45% to about 65%, or about 40% to about 60% by weight (calculated on a wet weight basis). In some embodiments, the moisture content of the tobacco extract is about 35% to about 65%, or about 35% to about 55% by weight (calculated on a wet weight basis). In some embodiments, the nicotine content of the tobacco extract is about 1% to about 5% by weight (calculated on a wet weight basis).

[0075] In some embodiments, the dry flavor and / or active delivery composition may comprise at least about 45%, at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, or at least about 95% by weight of tobacco solids (calculated on a dry weight basis). Additionally or alternatively, the flavor and / or active delivery composition may comprise up to about 99%, up to about 98%, up to about 95%, up to about 90%, or up to about 80% by weight of tobacco solids. In some embodiments, the dry flavor and / or active delivery composition may comprise from about 60 to about 80% by weight of tobacco solids (calculated on a dry weight basis).

[0076] In some embodiments, the tobacco extract is an aqueous tobacco extract. In some embodiments, the tobacco extract may be concentrated and then diluted before being added to the precursor material and dried. In other embodiments, the tobacco extract may not be concentrated and may be used directly to the precursor material.

[0077] The precursor material may be in the form of a slurry, suspension, gel, liquid or solid, but in some potentially preferred embodiments is in the form of a suspension or liquid, hi some embodiments, particles of solid material may be removed from the extract and / or precursor material by filtration and / or centrifugation.

[0078] In some embodiments, it may be desirable for any particles in the precursor composition to have an average particle size of about 3 mm or less, 1 mm or less, about 0.5 mm or less, or to have an average particle size of about 0.3 mm or less, as measured by sieving or by observing the size of the particles by SEM.

[0079] The water content of the precursor material can be at least about 20% by weight, at least about 30% by weight, at least about 40% by weight, at least about 50% by weight, at least about 60% by weight, at least about 70% by weight, at least about 80% by weight, or at least about 90% by weight on a wet weight basis.

In some embodiments, the water content of the precursor material is about 40% to about 50% by weight (50% to 60% v / v%) on a wet weight basis. When the water content of the precursor material is low, the spray / freeze drying process is quicker because there is less water to remove.

[0080] In some embodiments, the dried fragrance and / or active delivery composition and / or precursor material contains one or more active substances, which may be obtained from an extract or may be added. In some embodiments, an extract from a fragrance-containing or active-containing plant material contains the active substances.

[0081] The active substance may be a physiologically active material, which is a material intended to achieve or enhance a physiological response. The active substance may be selected from, for example, dietary supplements, nootropics, and psychotropic drugs. The active substance may include, for example, nicotine, caffeine, taurine, theine, vitamins such as B6 or B12 or C, melatonin, cannabinoids, or components, derivatives, or combinations thereof. The active substance may include one or more components, derivatives, or extracts of tobacco, cannabis, or another botanical substance.

[0082] In some embodiments, the active agent comprises nicotine, hi some embodiments, the active agent comprises caffeine, melatonin, or vitamin B12.

[0083] In some embodiments, the precursor material may include extracts from other plant source(s) along with or in place of tobacco extract.

[0084] As described herein, an extract may comprise or be derived from one or more plants or components, derivatives or extracts thereof. As used herein, the term "botanical" includes any material derived from a plant, including, but not limited to, extracts, leaves, bark, fiber, stems, roots, seeds, flowers, fruits, pollen, husks, shells, etc. Extracts may comprise or be derived from plants in the form of liquids, gases, solids, powders, dusts, crushed particles, granules, pellets, shreds, strips, sheets, etc. Exemplary botanicals include tobacco, eucalyptus, star anise, hemp, cocoa, cannabis, fennel, lemongrass, peppermint, spearmint, rooibos, chamomile, flax, ginger, ginkgo, hazel, hibiscus, bay, licorice, matcha, yerba mate, orange peel, papaya, rose, sage, tea, such as green or black tea, thyme, cloves, cinnamon, coffee, aniseed, basil, bay leaf, cardamom, coriander, cumin, nutmeg, oregano, paprika, rosemary, saffron, Lavender, lemon peel, mint, juniper, elderflower, vanilla, wintergreen, shiso, curcuma, turmeric, sandalwood, cilantro, bergamot, orange blossom, myrtle, blackcurrant, valerian, pimento, mace, damiane, marjoram, olive, lemon balm, lemon basil, chives, Calvi, verbena, tarragon, geranium, mulberry, ginseng, theanine, theacrine, maca, ashwagandha, damiana, guarana, chlorophyll, baobab, or any combination thereof.

[0088] The flavour and / or active delivery composition and / or precursor material may comprise one or more cannabinoid compounds selected from the group consisting of cannabidiol (CBD) and THC (tetrahydrocannabinol).

[0089] The flavor and / or active delivery composition and / or precursor material may include cannabidiol (CBD).

[0090] The flavour and / or active delivery composition and / or precursor materials may include nicotine and cannabidiol (CBD).

[0091] The flavouring and / or active delivery composition and / or precursor materials may include nicotine, cannabidiol (CBD), and THC (tetrahydrocannabinol).

[0092] In some embodiments, the perfume and / or active delivery composition and / or precursor material further comprises one or more excipients. In some embodiments, the excipients stabilize and preserve the precursor material, and the inventors have found the inclusion of excipients particularly important for stability when the precursor material comprises glycerol. The excipients may also act as bulking or filler materials. In some embodiments, the inclusion of excipients can also improve the handling of the dried material and help the dry aerosol-generating material retain its granular morphology by helping to reduce moisture uptake and increase the cohesiveness of the resulting material. The presence of excipients may also affect the rate of (freeze) drying.

[0093] Suitable excipients include mannitol, sucrose, trehalose, lactose, sorbitol, raffinose, maltose, dextrans such as dextran 10, dextran 70, dextran 90, maltodextrin, gelatin, agar, cyclodextrin, and polyethylene glycols such as PEG 2000-6000 and polyvinylpyrrolidone (PVP10).

[0094] In some embodiments, the perfume and / or active delivery composition and / or precursor material comprises one or more excipients in an amount of 0 to about 40% by weight on a wet weight basis. In some embodiments, the precursor material may comprise at least about 1%, at least about 10%, at least about 20%, at least about 30%, and / or up to about 40%, up to about 30%, up to about 20%, or up to about 10% by weight of excipients on a wet weight basis.

[0095] In some embodiments, the fragrance and / or active delivery composition may comprise at least about 0.1% by weight, at least about 10% by weight, at least about 20% by weight, or at least about 25% by weight of excipients (calculated on a dry weight basis). In some embodiments, the fragrance and / or active delivery composition may comprise up to about 25% by weight, up to about 20% by weight, up to about 15% by weight, or up to about 10% by weight of excipients (calculated on a dry weight basis).

[0096] In an exemplary embodiment, the flavor and / or active delivery composition comprises, on a dry weight basis, about 36% glycerol, about 45% tobacco extract, and about 19% excipients.

[0097] In another exemplary embodiment, the flavor and / or active delivery composition comprises, on a dry weight basis, from about 17 to about 39% glycerol, from about 41 to about 76% tobacco extract, and from 0 to about 28% excipients.

[0098] In embodiments where the excipient is agar, the precursor material may comprise about 0%, about 5%, or about 10% by weight of agar. The inventors have found that when the precursor material comprises a lower concentration of the agar excipient, the agar makes the precursor material more viscous and the freeze-drying process is easier.

[0099] In some embodiments, the precursor material comprises about 50% by weight tobacco extract, 0 to about 36% by weight aerosol forming agent (e.g., 0 to about 15% v / v), and 0 to about 40% by weight excipients (e.g., about 37.5% v / v). The tobacco extract may comprise about 55% by weight tobacco solids, with the total tobacco solids content of the precursor material being about 27.5% by weight.

[0100] In some embodiments, the precursor material comprises about 50% by weight tobacco extract, up to about 36% by weight (e.g., about 15% v / v) glycerol, and 0 to about 40% by weight (e.g., about 37.5% v / v) excipients. The tobacco extract may comprise about 55% by weight tobacco solids, with the total tobacco solids content of the precursor material being about 27.5% by weight.

[0101] Some sample formulations of dry aerosol-forming materials formed from aqueous tobacco extracts are summarized in Table 1 below, with amounts provided on a dry weight basis. These are theoretical values ​​(before drying and inherent losses). Typically, about 80-89% of the glycerol is retained after drying. Glycerol may be used as the aerosol-forming material, but may be replaced or partially replaced with one or more other aerosol-forming materials, such as those disclosed herein. The excipient used may be dextran, e.g., dextran 70. Again, this may be replaced or partially replaced with alternative excipients, such as those disclosed herein.

[0107] In some embodiments, the fragrance may include a sensory elicitor, which is intended to achieve somatic sensations that are usually chemically induced and perceived by stimulation of the fifth cranial nerve (trigeminal nerve) in addition to or instead of the scent or taste nerves, and may include agents that produce a heating, cooling, tingling, or numbing effect. A suitable heating agent may be, but is not limited to, vanillyl ethyl ether, and a suitable cooling agent may be, but is not limited to, eucalyptol, WS-3.

[0108] In some embodiments, the fragrance and / or active delivery composition and / or precursor materials include one or more other functional materials, which may include one or more of a pH adjuster, a colorant, a preservative, a filler, a stabilizer, and / or an antioxidant.

[0109] In some embodiments, the flavor and / or active delivery composition and / or precursor material includes a filler component. The filler component is generally a non-tobacco component, i.e., a component that does not include tobacco-derived raw materials. In some embodiments, the precursor material includes less than 60% by weight of filler, such as 1% to 60% by weight, or 5% to 50% by weight, or 5% to 30% by weight, or 10% to 20% by weight on a wet weight basis.

[0110] When present, the filler may include one or more inorganic filler materials such as calcium carbonate, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, magnesium carbonate, and suitable inorganic adsorbents such as molecular sieves. The filler may also include one or more organic filler materials such as wood pulp, hemp fiber, cellulose and cellulose derivatives.

[0111] In some embodiments, the perfume and / or active delivery composition is in the form of a gel. The gelling agent may be added to the perfume and / or active delivery composition, the precursor material, or may be optionally omitted. The gelling agent includes one or more compounds selected from cellulosic gelling agents, non-cellulosic gelling agents, guar gum, acacia gum, and mixtures thereof.

[0112] In some embodiments, the cellulosic gelling agent is selected from the group consisting of hydroxymethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, carboxymethylcellulose (CMC), hydroxypropylmethylcellulose (HPMC), methylcellulose, ethylcellulose, cellulose acetate (CA), cellulose acetate butyrate (CAB), cellulose acetate propionate (CAP), and combinations thereof.

[0113] In some embodiments, the gelling agent comprises (or is) one or more of hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methylcellulose (HPMC), carboxymethyl cellulose, guar gum, or acacia gum.

[0114] In some embodiments, the gelling agent comprises (or is) one or more non-cellulosic gelling agents, including, but not limited to, agar, xanthan gum, gum arabic, guar gum, locust bean gum, pectin, carrageenan, starch, alginate, and combinations thereof.

[0115] The perfume and / or active delivery composition and / or precursor material may include an acid. The acid may be an organic acid. In some of these embodiments, the acid may be at least one of a monoprotic acid, a diprotic acid, and a triprotic acid. In some such embodiments, the acid may contain at least one carboxyl functional group. In some such embodiments, the acid may be at least one of an alpha-hydroxy acid, a carboxylic acid, a dicarboxylic acid, a tricarboxylic acid, and a keto acid. In some such embodiments, the acid may be an alpha-keto acid.

[0116] In some such embodiments, the acid may be at least one of succinic acid, lactic acid, benzoic acid, citric acid, tartaric acid, fumaric acid, levulinic acid, acetic acid, malic acid, formic acid, sorbic acid, benzoic acid, propanoic acid, and pyruvic acid.

[0117] In other embodiments, the acid may be an inorganic acid. In some of these embodiments, the acid may be a mineral acid. In some such embodiments, the acid may be at least one of sulfuric acid, hydrochloric acid, boric acid, and phosphoric acid.

[0118] The inclusion of an acid may be beneficial in embodiments in which the flavor and / or active delivery composition and / or precursor material includes nicotine. In such embodiments, the presence of an acid may stabilize dissolved species in the slurry from which the aerosol-forming material is formed. The presence of an acid may reduce or substantially prevent evaporation of nicotine during drying of the slurry, thereby reducing loss of nicotine during production.

[0119] In certain embodiments, the perfume and / or active delivery composition comprises a gelling agent that includes a cellulosic and / or non-cellulosic gelling agent, an active and an acid.

[0120] The dried fragrance and / or active delivery composition may be in any solid form. For example, the fragrance and / or active delivery composition may be in the form of particles, granules, or powder. The fragrance and / or active delivery composition may be in monolithic form, tablet, agglomerate, or "cake" form. In some embodiments, the fragrance and / or active delivery composition is formed by freeze-drying or spray-drying, and then processed as necessary by other suitable steps known to those skilled in the art to provide a dried material in the desired form, for example, in the form of particles of the desired size(s).

[0121] In some embodiments, the perfume and / or active delivery composition is in the form of granules.The granules can be of any size, cross-sectional shape or mass.The perfume and / or active delivery composition in the form of granules is advantageous due to its high surface area to volume ratio, which positively affects the release of ingredients, including perfume and / or active, from the material.

[0122] In some embodiments, the perfume and / or active delivery composition is free-flowing and non-sticky, which aids in further processing and handling of the perfume and / or active delivery composition.

[0123] Smaller granules and particles have a larger surface area to volume ratio and therefore may exhibit enhanced release of components compared to larger sized particles.

[0124] In some embodiments, the particles in the precursor composition have an average particle size of about 3 mm or less, 1 mm or less, 500 μm or less, about 200 μm or less, 100 μm or less, about 50 μm or less, 40 μm or less, about 30 μm or less, 20 μm or less, about 10 μm or less, about 5 μm or less, or desirably have an average particle size of about 1 μm or less, as measured by sieving.

[0125] In some embodiments, the average particle size is in the range of about 0.1 μm to about 1 mm, about 1 μm to about 500 μm, about 10 μm to about 200 μm, about 10 μm to about 100 μm, or about 10 μm to about 50 μm. In some embodiments, at least about 90% of the particles of the precursor composition have a particle size in the range of about 1 μm to about 1 mm, or about 10 to about 500 μm, or about 50 to about 200 μm. In some embodiments, at least about 90% of the tobacco particles of the precursor composition have a particle size in the range of about 1 μm to about 1 mm, or about 10 to about 500 μm, or about 50 to about 200 μm. In some embodiments, at least about 90% of the tobacco particles of the precursor composition have a particle size in the range of about 1 μm to about 1 mm, or about 10 to about 500 μm, or about 50 to about 200 μm. In some embodiments, at least about 90% of the tobacco particles of the precursor composition have a particle size in the range of about 1 μm to about 1 mm, or about 10 to about 500 μm, or about 50 to about 200 μm. In some embodiments, none of the particles in the precursor composition have a particle size greater than 1 mm, greater than 0.5 mm, greater than 0.2 mm, greater than 0.15 mm, or greater than about 0.1 mm. In some embodiments, the average particle size is less than 50 μm.

[0126] When preparing the dried precursor composition, the particle size of any solid material present can be reduced by grinding, shredding, cutting or crushing the plant material. Suitable machines for making such plant particles include, for example, shredders, cutters, or mills, such as hammer mills, roller mills or other types of commercially available milling machines. The size of the plant particles is selected to result in particles that can be readily prepared from a variety of different types of plant material having the characteristics described herein and that provide a source of readily releasable plant components.

[0127] Smaller size of the perfume and / or active delivery composition particles may be advantageous for releasing perfume and / or active. Without wishing to be bound by any particular theory, smaller particles may have a larger surface area to volume ratio, which may improve release. In some embodiments, the dried perfume and / or active delivery composition easily forms particles with an average size of less than 1 mm. In some embodiments, the particles may be as small as 10 μm, or as small as 1 μm. The size of the particles can be determined by sieving or by observing the particles by SEM.

[0128] In some embodiments, the lyophilized precursor material can be ground into particles and sieved to remove particles that are deemed too small or too large for use as a flavor and / or active delivery composition.

[0129] In some embodiments, the perfume and / or active delivery composition used in the present invention has a particle size distribution D10 of about 5 to about 25 μm (meaning that 10% of the particles in the test sample are smaller than the value), a particle size distribution D50 of about 30 to about 200 μm (meaning that 50% of the particles in the test sample are smaller than the value), and a particle size distribution D90 of about 500 to about 2500 μm (meaning that 90% of the particles in the test sample are smaller than the value). These values ​​are determined using a particle size analyzer Microtrac CamSizer® X2. The percentages referred to herein are volume percentages.

[0130] In some embodiments, the lyophilized materials used as flavor and / or active delivery compositions according to the present invention have a particle size distribution D10 of about 8 to about 15 μm, a particle size distribution D50 of about 50 to about 150 μm, and a particle size distribution D90 of about 900 to about 1700 μm.

[0131] In some embodiments, the D10 average is from about 10 to about 15 μm, the D50 average is from about 40 to about 140 μm, and the D90 average is from about 800 to about 1600 μm.

[0132] Spray drying and freeze drying The drying method used to dry the precursor material can be any suitable drying process, including freeze-drying or spray-drying processes. The drying process used must be compatible with the precursor material and the desired composition of the fragrance and / or active delivery composition. Since it may be desirable for the fragrance and / or active delivery composition to contain active and / or fragrance substances derived from the extract in the precursor material, it is important to select a drying method that retains sufficient amounts of these components.

[0133] In a small scale example, the precursor material is freeze-dried using a freeze-drying microscope, for example a Lyostat freeze-drying microscope.

[0134] In the spray drying process, precursor material is sprayed and dried rapidly using hot gas.The use of spray drying provides several advantages to the present invention, such as dry particle size can be controlled and consistent, tobacco or flavor extracts or materials are heat sensitive, but can still be spray dried at relatively high inlet temperatures, short residence times are required in the spray drying equipment, and loss of flavor / volatile substances is minimal.This makes the process adaptable to reduce loss of volatile compounds and maintain the desired flavor of flavor and / or active delivery composition.

[0135] Lyophilization, also known as cryodesication, is a process in which precursor materials are frozen, the temperature is reduced, and water is removed by sublimation under reduced pressure conditions. Without wishing to be bound by any particular theory, it is believed that the low processing temperature and the rapid water loss by sublimation avoids alteration of the properties of the perfume and / or active delivery composition. This process preserves the structure of the precursor materials and reduces the loss and decomposition of volatile perfume compounds.

[0136] The dried perfume and / or active delivery composition has a lower moisture content than the precursor material. The moisture content of the perfume and / or active delivery composition can be up to about 0.5% by weight, about 1% by weight, about 2% by weight, about 5% by weight, about 10% by weight, or about 20% by weight (calculated on a wet weight basis). The moisture content of the dried perfume and / or active delivery composition may be reduced by at least about 50% by weight, about 60% by weight, about 70% by weight, about 80% by weight, about 90% by weight, about 95% by weight, about 98% by weight, or about 100% by weight from the precursor material. In some embodiments, the dried perfume and / or active delivery composition has a moisture content of less than about 5% by weight, less than about 4% by weight, less than about 3% by weight, less than about 2% by weight, or less than about 1% by weight (calculated on a wet weight basis) as measured by gas chromatography-thermal conductivity detector (GC-TCD) or Karl Fischer titration.

[0137] In an exemplary embodiment of the present invention, the precursor material comprises Burley tobacco extract and a moisture content of 60% by weight. After the freeze-drying operation described herein, the dried flavor and / or active delivery composition has a moisture content of 3% by weight.

[0138] The lower moisture content of dried perfume and / or active delivery composition is associated with longer shelf life and stability.However, very low moisture content may be associated with brittle structure and smaller particle size, and longer processing time.The material is also very hygroscopic.On the other hand, if the moisture content of dried perfume and / or active delivery composition is too high, the desired stability improvement may not be achieved.Dried perfume and / or active delivery composition is also not easy to handle at higher moisture content, and the material may become sticky.

[0139] The inventors have found that when a precursor material includes an excipient, the precursor material may be more suitable for drying by spray drying (compared to a precursor material that does not include an excipient). Without wishing to be bound by any particular theory, it is speculated that increasing the amount of excipient in the precursor material increases the glass transition temperature above 100° C., which affects the physical properties of the material making it more suitable for spray drying.

[0140] Aerosol generation The permeable container containing the fragrance and / or active delivery composition disclosed herein can be used to generate an aerosol.

[0141] An aerosol-forming material is a material that is capable of generating an aerosol when, for example, heated, irradiated, or in any other way energized.

[0142] Conventional aerosol generating materials, including tobacco materials or tobacco extracts, can be used in combustion and non-combustion aerosol generating devices, including hybrid devices and tobacco heating products, to provide users with an aerosol with authentic tobacco taste and texture. One problem encountered with such materials is that the content of flavors, other volatile compounds, and nicotine decreases with storage of the aerosol generating material, especially toward the end of the material's life. This is because the more volatile components, including nicotine and many flavors and aromas, are easily released from the material. Furthermore, when the moisture content of the aerosol generating material increases due to moisture absorption, the release of substances such as nicotine and flavors is adversely affected. Aerosol generating materials produced using conventional methods and procedures generally need to be used within 1-3 days of production. Thus, there is a need to improve the shelf life of aerosol generating materials.

[0143] A further problem associated with conventional aerosol-forming materials that include tobacco materials or tobacco extracts is that the concentrations of desired components, such as nicotine and flavors, are relatively low. This limits the concentration of these desired components in the generated aerosol. Furthermore, this means that a relatively large amount of the aerosol-forming material is required, and therefore a large amount of energy is required to heat the aerosol-forming material to release the desired components.

[0144] A further advantage of the fragrance and / or active delivery compositions disclosed herein used as solid substrates for aerosol generation is that the low water content reduces the problems associated with "hot puffs" as known in the art.

[0145] In some embodiments, a permeable container holding a fragrance and / or active delivery composition is used to generate an aerosol for inhalation by a user.

[0146] An advantage of the permeable containers holding the flavor and / or active delivery compositions is that they can be used as solid aerosol generating substrates in hybrid systems or tobacco heating products (THPs), making the present invention versatile enough to be used in a variety of products without the need for further processing.

[0147] When the perfume and / or active delivery composition is used as an aerosol generating material, the composition may include an aerosol forming material. In some embodiments, the aerosol forming material is included in the precursor material. Alternatively or additionally, the aerosol forming material may be added to the dried perfume and / or active delivery composition.

[0148] The aerosol-forming material may include one or more components capable of forming an aerosol. The aerosol-forming agent may be, for example, a polyol aerosol generating agent or a non-polyol aerosol generating agent. It may be a solid or liquid at room temperature, but is preferably a liquid at room temperature.

[0149] In some embodiments, the aerosol forming material may include one or more of glycerin, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, mesoerythritol, ethyl vanillate, ethyl laurate, diethyl suberate, triethyl citrate, triacetin, diacetin mixtures, benzyl benzoate, benzyl phenyl acetate, tributyrin, lauryl acetate, lauric acid, myristic acid, and propylene carbonate.

[0150] In some embodiments, the aerosol forming agent comprises one or more polyhydric alcohols such as propylene glycol, triethylene glycol, 1,3-butanediol, and glycerin, esters of polyhydric alcohols such as glycerol mono-, di-, or triacetate, and / or aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanedioate and dimethyl tetradecanedioate. In some embodiments, the aerosol forming material comprises one or more compounds selected from erythritol, propylene glycol, glycerol, vegetable glycerin (VG), triacetin, sorbitol, and xylitol.

[0151] In some embodiments, the aerosol-forming material comprises, consists essentially of, or consists of glycerol. Glycerol provides a visible aerosol when the aerosol generating device is used. Aerosol generating devices that provide a visible aerosol are generally preferred by consumers because they allow them to visualize the product and what they are consuming. This makes glycerol a desirable choice for the aerosol-forming material. Propylene glycol has the advantage of being a better perfume carrier than glycerol.

[0152] Combinations of two or more aerosol forming agents may be used, in equal or differing proportions.

[0153] In some embodiments, the precursor material comprises at least about 1%, at least about 5%, at least about 10%, or at least about 20% by weight of aerosol-forming material (calculated on a wet weight basis). Additionally or alternatively, the precursor material may comprise up to about 40%, up to about 35%, up to about 30%, up to about 25%, up to about 20%, or up to about 10% by weight of aerosol-forming material (calculated on a wet weight basis).

[0154] In embodiments of the invention in which the aerosol-forming material is glycerol, the precursor material may contain up to 36% glycerol by weight. The inventors have demonstrated that dry weight content levels of aerosol-forming material of up to 36% by weight (calculated on a dry weight basis) are possible.

[0155] The amount of glycerol in precursor material, and thus in dried fragrance and / or active delivery composition, is important, since it is both an aerosol forming material and a plasticizer.Too high a concentration of glycerol can be detrimental to the critical temperature of the product during the freeze-drying process, and can lead to the collapse of the product when the critical temperature of the formulation is exceeded.On the other hand, sufficient glycerol should be included to provide sufficient and pleasant aerosol to the consumer.

[0156] It is particularly surprising that precursor materials including glycerol and some other aerosol forming materials can be freeze-dried because such materials are believed to have antifreeze properties. Nevertheless, the inventors have discovered that precursor materials including glycerol can be freeze-dried to form highly useful fragrance and / or active delivery compositions.

[0157] In some embodiments, the dry fragrance and / or active delivery composition may comprise at least about 1% by weight, at least about 5% by weight, at least about 10% by weight, at least about 20% by weight, at least about 30% by weight, or at least about 40% by weight of aerosol-forming material (calculated on a dry weight basis).

[0158] In some embodiments, the dry flavor and / or active delivery composition may comprise from about 1 to about 34% by weight, or from about 17 to about 34% by weight, of the aerosol-forming material (calculated on a dry weight basis). In some embodiments where the aerosol-forming material is glycerol, the dry flavor and / or active delivery composition may comprise from about 13 to about 34% by weight, of glycerol (calculated on a dry weight basis).

[0159] In embodiments in which burley tobacco is used, the flavor and / or active delivery composition may comprise about 17 to about 36% by weight of glycerol. The amount of glycerol in the flavor and / or active delivery composition is important since it is both an aerosol forming material and a plasticizer. If the concentration of glycerol is too high, it may be detrimental to the critical temperature of the product during the freeze-drying process, and may result in the collapse of the product if the critical temperature of the formulation is exceeded. On the other hand, sufficient glycerol should be included to provide a sufficient and pleasant aerosol to the consumer.

[0160] In some embodiments, the perfume and / or active delivery composition and / or precursor material further comprises one or more excipients. In some embodiments, the excipients stabilize and preserve the precursor material, and the inventors have found that the inclusion of an excipient is particularly important for stability when the precursor material comprises glycerol as an aerosol forming material.

[0161] In some embodiments, the container and / or the fragrance and / or active delivery composition includes one or more additives that are released upon heating of the fragrance and / or active delivery composition, thus contributing to the generated aerosol.

[0162] In some cases, the total weight of the fragrance and / or active delivery composition contained in the container is up to about 200 mg, up to about 190 mg, up to about 180 mg, up to about 170 mg, up to about 160 mg, up to about 150 mg, up to about 140 mg, up to about 130 mg, up to about 120 mg, up to about 110 mg, up to about 100 mg, up to about 90 mg, up to about 80 mg, up to about 70 mg, up to about 60 mg, or up to about 50 mg.

[0163] Alternatively or additionally, the total mass of the included fragrance and / or active delivery composition may be at least about 5 mg, at least about 10 mg, at least about 15 mg, at least about 20 mg, at least about 25 mg, at least about 30 mg, at least about 35 mg, at least about 40 mg, at least about 45 mg, or at least about 50 mg.

[0164] In some embodiments, the total mass of the flavor and / or active delivery composition is sufficient to provide, for example, up to about 10 puffs of aerosol generated in a single session or over a series of multiple sessions, In such embodiments, the total mass of dry aerosol-generating material provided is from about 10 to 100 mg, or from about 25 to about 50 mg.

[0165] The container has suitable dimensions to contain this amount of fragrance and / or active delivery composition, yet is also of a size that is easy to manufacture and handle.

[0166] In some embodiments, the perfume and / or active delivery composition may be incorporated into a container without the need for a carrier or other substrate material that requires heating.

[0167] However, in some embodiments, the perfume and / or active delivery composition may be combined with a carrier or substrate prior to being placed in the container.

[0168] In some embodiments, the flavoring and / or active delivery composition is combined with additional aerosol-generating materials, such as tobacco-containing materials. For example, the flavoring and / or active delivery composition may be combined with tobacco materials. The tobacco may be pre-treated or untreated, for example, solid stem (SS), shredded dried stem (SDS), steam-treated stem (STS), or any combination thereof. The tobacco material may be fermented, cured, uncured, roasted, or otherwise pre-treated. The tobacco material may be provided in the form of cut rag tobacco. The cut rag tobacco may have, for example, a cut width of at least 15 cuts / inch (about 5.9 cuts / cm, which corresponds to a cut width of about 1.7 mm). The cut rag tobacco may be formed from a mixture of forms of tobacco materials, such as a mixture of one or more of paper reconstituted tobacco, leaf tobacco, extruded tobacco, and band cast tobacco.

[0169] In other embodiments, the fragrance and / or active delivery composition may be combined with additional aerosol-generating materials including gelling agents, aerosol forming agents, and amorphous solids such as dry compositions comprising one or more fragrances and / or actives.

[0170] In some embodiments, the container contains a heating material and / or the fragrance and / or active delivery composition comprises a heating material. The heating material comprises one or more materials selected from the group consisting of conductive materials, magnetic materials, and magnetic conductive materials. In some embodiments, the heating material may comprise a metal or metal alloy. In some embodiments, the heating material may comprise one or more materials selected from the group consisting of aluminum, gold, iron, nickel, cobalt, conductive carbon, graphite, flat carbon steel, stainless steel, ferritic stainless steel, copper, and bronze.

[0171] In some embodiments, the heating material may be heated by induction heating, a process in which a conductive object is heated by penetrating a varying magnetic field into the conductive object. In some embodiments, the heating material may be heated by resistive heating. In such embodiments, the heating material is connected to a power source. Alternatively, the heating may be microwave heating or infrared heating.

[0172] In some embodiments, the heating material is surrounded by the perfume and / or active delivery composition. In some embodiments, the heating material is in the form of a mesh or perforated sheet, strip or ribbon. In some embodiments, the heating material is in particulate form. In some embodiments, the heating material is the perfume and / or active delivery composition or a coating on the container. It may be preferred that the heating material contacts the perfume and / or active delivery composition.

[0173] Aerosol Delivery System The article of manufacture, including the container containing the fragrance and / or active delivery composition, may be used in a combustion or non-combustion aerosol delivery system.

[0174] In some embodiments, the product is used as or is included in a consumable product.

[0175] The high concentration of perfume and / or active provided by the perfume and / or active delivery composition of the present disclosure means that when heated, the composition can provide an aerosol containing a high concentration of these desirable ingredients.Furthermore, the small amount of composition required means that aerosols can be generated quickly once heating is initiated, since the mass of the composition to be heated is very small.Furthermore, heating these compositions is very energy efficient, since there may be very little material in the composition that does not contribute to the aerosol.

[0176] A consumable is an article that contains aerosol-generating material, some or all of which is intended to be consumed during use by a user. In this case, the aerosol-generating material, or at least a portion of the aerosol-generating material, is a fragrance and / or active delivery composition, and is provided in a container as disclosed herein. Additional aerosol-generating material may be provided in the container or elsewhere in the consumable.

[0177] In aerosol-generating embodiments, the fragrance and / or active delivery composition may be used as or referred to as an aerosol-generating material.

[0178] The consumable may comprise one or more other components, such as an aerosol-generating material storage region, an aerosol-generating material transfer component, an aerosol-generating region, a housing, a wrapper, a mouthpiece, a filter, and / or an aerosol modifier.

[0179] The consumable may also include an aerosol generator, such as a heater that generates heat during use to cause the aerosol-generating material to generate an aerosol. The heater may comprise, for example, a material that can be heated by electrical conduction, or a susceptor. The heater, in some embodiments, may be provided within the container along with the fragrance and / or active delivery composition. In some embodiments, the heater may form part of the container.

[0180] The permeability of the container can aid in the transfer of heat from a heat source outside the container to the composition held within the container. In some embodiments, at least a portion of the container includes a thermally conductive material to enhance the heating of the perfume and / or active delivery composition held therein. In some embodiments, a heating material or heated heating material can be provided within the container along with the perfume and / or active delivery composition, as described above.

[0181] The consumable may be of any shape or size suitable for the aerosol generating device, in a preferred embodiment of the invention the consumable is rod shaped.

[0182] In some embodiments, the container containing the flavorant and / or active delivery composition is provided in an aerosol generating device, such as a tobacco heating product (THP) or a hybrid e-cigarette product. Suitably, the container may be used directly as a solid substrate, where the container is heated directly without combustion to provide an inhalable aerosol.

[0183] In some embodiments, heating the container first heats the flavor and / or active delivery composition and volatilizes or aerosolizes its components, including the flavor and / or active components to be delivered, and then releases the aerosolized components, such as glycerol, nicotine, and / or tobacco flavors.

[0184] The delivery systems described herein can be combustion aerosol delivery systems or non-combustion aerosol delivery systems.

[0185] As used herein, the term "delivery system" is intended to encompass a system that delivers at least one substance to a user, Combustion aerosol delivery systems, such as cigarettes, cigarillos, cigars, and tobacco for pipes or for roll-your-own or hand-made cigarettes, whether based on tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, tobacco substitutes, or other smokable materials; and non-combustion aerosol delivery systems that release compounds from an aerosol-forming material without combusting the aerosol-forming material, such as e-cigarettes, tobacco heating products, and hybrid systems that generate an aerosol using a combination of aerosol-forming materials.

[0186] According to the present disclosure, a "combustion-based" aerosol delivery system is a system in which the constituent aerosol-generating materials (or components thereof) of the aerosol delivery system are combusted or burned during use to facilitate delivery of at least one substance to a user.

[0187] In some embodiments, the delivery system is a combustion aerosol delivery system, such as a system selected from the group consisting of a cigarette, a cigarillo, and a cigar.

[0188] In some embodiments, the present disclosure relates to components for use in combustion aerosol delivery systems, for example, aerosol modifier-releasing components such as filters, filter rods, filter segments, tobacco rods, spills, capsules, threads or beads, or papers such as plug wrap, tipping paper or cigarette paper.

[0189] According to the present disclosure, a "non-combustion" aerosol delivery system is one in which the constituent aerosol-generating materials (or components thereof) of the aerosol delivery system are not combusted or burned to facilitate delivery of at least one substance to a user.

[0190] In some embodiments, the delivery system is a non-combustion aerosol delivery system, such as a powered non-combustion aerosol delivery system.

[0191] In some embodiments, the non-combustion aerosol delivery system is an electronic cigarette, also known as a vaping device or electronic nicotine delivery system (END), although it should be noted that the presence of nicotine in the aerosol-generating material is not a requirement.

[0192] In some embodiments, the non-combustion aerosol delivery system is an aerosol-generating material heating system, also known as a non-combustion heating system. One example of such a system is a tobacco heating system.

[0193] Typically, a non-combustion aerosol delivery system may include a non-combustion aerosol delivery device and a consumable for use with the non-combustion aerosol delivery device.

[0194] In some embodiments, the present disclosure relates to consumables that include a container containing an aerosol-generating material and that are configured for use with a non-combustion aerosol delivery device. These consumables may be referred to as articles throughout this disclosure.

[0195] In some embodiments, the non-combustion aerosol delivery system, such as the non-combustion aerosol delivery device, may include a power source and a controller. The power source may be, for example, a power source or a heat generating power source. In some embodiments, the heat generating power source includes a carbon substrate that can be energized to deliver power in the form of heat to a composition including the aerosol generating material and the moisture impermeable coating or to a heat transfer material in proximity to the heat generating power source.

[0196] In some embodiments, the non-combustion aerosol delivery system may include a consumable, an aerosol generator, an aerosol-generating region, a housing, a mouthpiece, a filter, and / or a region or chamber for receiving an aerosol modifier.

[0197] The present invention also relates to devices having a chamber for receiving one or more consumables. The chamber may be opened, for example, to allow a user to insert the consumable, and then closed or sealed to prevent the consumable from falling out of the chamber. In some embodiments, the device may include a mechanism for holding or gripping the consumable once it is placed in a receiving area or chamber of the device.

[0198] The region or chamber for receiving the consumable may be surrounded by a heat source such that heat is transferred to the consumable and the aerosol generating material held therein, or alternatively, heat from another heat source within the device may be transferred to the consumable within the chamber or region.

[0199] In some embodiments, a consumable for use with a non-combustion aerosol delivery device may include a composition including an aerosol-generating material and a moisture impermeable coating, an aerosol-generating material storage region, an aerosol-generating material transport component, an aerosol generator, an aerosol-generating region, a housing, a wrapper, a filter, a mouthpiece, and / or an aerosol modifier.

[0200] In some embodiments, the substance to be delivered may be an aerosol-generating material provided in a container, and optionally another aerosol-generating material that may or may not be heated. If desired, the aerosol-generating material in the container and any other aerosol-generating materials may include one or more active ingredients, one or more flavorings, one or more aerosol-forming materials, and / or one or more other functional materials.

[0201] In some embodiments, a permeable container containing a flavorant and / or active delivery composition is used to provide an aerosol-generating material, which is a tobacco heating system. This may be in place of or in addition to another aerosol-generating material, such as a tobacco composition. The container and / or the flavorant and / or active delivery composition can be heated directly or indirectly to generate an aerosol from the flavorant and / or active delivery composition. The permeability of the container means that it does not need to be removed or opened before use.

[0202] The contents of the container may be sufficient to provide aerosol for a single puff or a series of puffs. In certain embodiments, the contents of the container provide 6-9 puffs of aerosol when heated. In such embodiments, the flavor and / or active delivery composition produces an aerosol having a high concentration of flavor and / or active, which can provide authentic tobacco taste and nicotine delivery.

[0203] In some embodiments, the very small size of the container and the very concentrated nature of the flavor and / or active delivery composition means that the aerosol delivery system can be designed to be small and unobtrusive.As mentioned above, the amount of energy required to operate the system is much less than that required by conventional tobacco heating devices.In addition, the aerosol generated is much more satisfying with a high concentration of flavor and / or active.

[0204] 2 is a cross-sectional view of one example of a tobacco heating product for heating an aerosol-forming material. The device 11 has a heating chamber 14 containing a permeable container 13 that contains a flavorant and / or active delivery composition that is heated and volatilized in use.

[0205] The device 11 of FIG. 2 further includes an electronics / power chamber 16 that may contain, for example, an electrical control circuit and / or a power source (not shown). The electrical control circuit may include a controller, such as a microprocessor arrangement, configured and designed to control the heating of the smokable material via a heating element (not shown). The electrical control circuit may receive a signal, for example, from a puff-activated sensor that is sensitive to changes in pressure or changes in airflow rate that occur, in use, for example, when a user initiates a draw on the device 11. The electrical control circuit may then operate to cause heating of the flavorant and / or active delivery composition on "demand". Various configurations for puff-activated sensors are available, including, for example, thermistors, electromechanical devices, mechanical devices, optical devices, opto-mechanical devices, and microelectromechanical systems (MEMS)-based sensors. Alternatively, the device may have a manually operable switch for the user to initiate a puff.

[0206] The heating chamber 14 is contained within the housing 12. Supports and / or insulating means (not shown) may be positioned between the heating chamber 14 and the housing 12, for example to help insulate the housing 12 from the heating chamber 14, so that the housing 12 does not get hot, or at least too hot to touch, during use.

[0207] The housing 12 includes an inlet 15 through which air is drawn into the device. The housing 12 also includes an outlet 17 at the mouthpiece 18 of the device 11. Air is drawn into the device 11 through the inlet 15, travels through the device and through the reservoir 13, picking up aerosol emitted by the flavor and / or active delivery composition. The resulting aerosol generated by the device 11 exits the device 11 through outlet 19 and is inhaled by the user.

[0208] In other embodiments, the non-combustion aerosol delivery system is a hybrid system that generates an aerosol using a combination of aerosol-generating materials, one or more of which may be heated, a composition including an aerosol-generating material, and a moisture impermeable coating. Each of the aerosol-generating materials may be, for example, 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. The solid aerosol-generating material may include, for example, a tobacco or non-tobacco product.

[0209] In some embodiments, a permeable container containing a flavor and / or active delivery composition is used in a hybrid system, where the flavor and / or active delivery composition is heated by steam generated by the system and drawn through the permeable container. Additionally or alternatively, the flavor and / or active delivery composition may be directly heated by an additional heat source. In such embodiments, the flavor and / or active delivery composition adds concentrated flavors and / or actives, such as real tobacco taste and nicotine delivery, to the aerosol.

[0210] 3 shows a cross-sectional view of one example of a hybrid product for heating a fragrance and / or active delivery composition and liquid. The device 21 has a housing 22 housing a chamber 24 that houses a container containing a fragrance and / or active delivery composition 23 that is heated and vaporized during use. The housing 22 also contains a liquid reservoir 25 that houses a liquid 26 that is heated to form a vapor.

[0211] The device 21 further includes an electronics / power chamber 27 that may contain, for example, electrical control circuitry and / or a power source (not shown). The electrical control circuitry may include a controller, such as a microprocessor arrangement, constructed and arranged to control the heating of the container 23 and / or its contents, and the liquid 26 via one or more heating elements (not shown). The electrical control circuitry may enable the device 21 to be puff-activated to cause heating "on demand". Alternatively, the device 22 may have a manually operable switch for a user to initiate a puff.

[0212] The housing 22 also includes an inlet 28 through which air is drawn into the device. The housing 22 also includes an outlet 29 at the mouthpiece 30 of the device 21. Air is drawn into the device 21 through the inlet 28 and travels through the device picking up vapor generated by heating the liquid 26 in the liquid reservoir 25, as well as flavorings and / or active ingredients released by the container 23, and the resulting aerosol generated by the device 21 exits the device 21 through the outlet 29 and is inhaled by the user.

[0213] The hybrid device 21 shown diagrammatically in Figure 3 represents just one possible configuration of such an apparatus. The relative positions of the liquid reservoir 25 and the chamber 24 for holding the container 23 can be varied, as can the path of the air flowing through the apparatus.

[0214] In one embodiment, the liquid reservoir is located upstream of the volatilizing smokable material. Alternatively, the liquid reservoir may be located downstream of the volatilizing smokable material. In yet another arrangement, two aerosol sources within the device can be positioned side-by-side, etc.

[0215] Oral Feeding System The product, which includes a permeable container containing the perfume and / or active delivery composition, may be used in or as an aerosol-free delivery system.

[0216] Aerosol-free delivery systems include, but are not limited to, lozenges, gums, patches, articles containing inhalable powders, and oral products such as oral tobacco, including snus or moist snuff, that deliver at least one substance to a user orally, nasally, transdermally, or otherwise without forming an aerosol, where the at least one substance may or may not contain nicotine.

[0217] The products disclosed herein may be configured for oral use to provide buccal delivery of flavors and / or actives.

[0218] In some embodiments, the permeable container is provided in such a manner that during oral use, saliva in the user's mouth passes through the permeable container and comes into contact with the flavor and / or active delivery composition. The saliva releases the flavor and / or active ingredients from the flavor and / or active delivery composition, and the saliva containing the released ingredients can exit the container so that they can be perceived in the mouth and / or absorbed into the bloodstream via mucous membranes in the oral cavity or by being swallowed by the user.

[0219] In some embodiments, the permeable container comprises or consists of a water-permeable pouch.

[0220] In some embodiments, the highly concentrated nature of the flavor and / or active delivery composition means that the container may be very small, for example a "micropouch" having dimensions smaller than conventional pouches provided for oral use, such as snus or moist snuff. As a result, these small pouches are less noticeable and more comfortable to use. Also, the amount of saliva required to release the flavor and / or active ingredients may be much less than conventional products. This means that the release of the ingredients can be much faster, providing a more immediate effect for the user. Indeed, in some embodiments, the release of the ingredients may begin within less than about 5 minutes, less than about 4 minutes, less than about 3 minutes, less than about 2 minutes, less than about 1 minute, or less than about 30 seconds after placing the product in the oral cavity.

[0221] Additionally, product use may, in some embodiments, be much more satisfactory at higher levels of fragrance and / or actives.

[0222] In some embodiments, the container holds not only the flavor and / or active delivery composition, but also additional flavor and / or active sources, such as a tobacco formulation. The tobacco formulation may be a formulation similar to those used in known oral tobacco products. In such embodiments, the flavor and / or active delivery composition provides an additional release of flavor and / or active ingredient(s) in addition to the ingredients delivered by the tobacco formulation. In such embodiments, the flavor and / or active delivery composition may provide an initial "hit" of flavor and / or activity before a slower, more sustained release that forms the tobacco formulation.

[0223] packaging In some embodiments, the product includes a moisture-impermeable coating that surrounds the perfume and / or active delivery composition, but may be separate from the perfume and / or active delivery composition. For example, the moisture-impermeable coating may surround the perfume and / or active delivery composition. In some embodiments, the moisture-impermeable coating may be provided as a film or wrapper, and may optionally be deposited on a moisture-permeable carrier.

[0224] In some embodiments, the product includes an adsorbent or desiccant material. As mentioned above, the adsorbent or desiccant material can be provided within the perfume and / or active delivery composition. Alternatively, these components may be provided separately in the product, but in such a way that the adsorbent still competes with the perfume and / or active delivery composition for moisture in the environment, thus reducing the amount of moisture absorbed by the perfume and / or active delivery composition. In some embodiments, the adsorbent may be provided in or on a wrapper that surrounds the perfume and / or active delivery composition in the product. In other embodiments, the adsorbent may be incorporated into a separate section of the product to the perfume and / or active delivery composition. If the product is heated to generate an aerosol, this may have the advantage of reducing the exposure of the adsorbent to the high temperatures to which the aerosol-generating material is heated during use. For example, the adsorbent may be located in an adjacent section of the product that is not directly heated. This may be downstream or upstream of the aerosol-generating material. In some embodiments, the adsorbent is included in one or more sections of the product that do not include the aerosol-generating material, such as the cooling element section or the filter section.

[0225] In yet another embodiment, the adsorbent may be separated or removed from the perfume and / or active delivery composition and / or product prior to use. For example, the adsorbent may be placed in a package in which the product is held prior to use. In some embodiments, the package may be a wrapper, box or other container. The adsorbent may be incorporated into the packaging material or part thereof. Alternatively, the adsorbent may be provided in a separate article, such as a sachet or sheet, that is placed with the product in the package.

[0226] stability The present invention enjoys the advantage of a longer shelf life than other tobacco extracts.

[0227] The nicotine content of the precursor and flavor and / or active delivery composition after the freeze-drying process is calculated to indicate the amount of nicotine retained after processing. The nicotine recovery of the dried flavor and / or active delivery composition compared to the original tobacco extract is at least about 76% by weight on a dry weight basis. The nicotine recovery of the dried flavor and / or active delivery composition compared to the original tobacco extract can be at least about 60%, at least about 70%, at least about 75%, at least about 80%, or at least about 90% by dry weight basis.

[0228] The glycerol content of the precursor and dried fragrance and / or active delivery composition after the freeze-drying process is calculated to indicate the amount of glycerol retained after processing. The glycerol recovery of the dried fragrance and / or active delivery composition compared to the precursor material is at least about 85%. The glycerol recovery of the dried fragrance and / or active delivery composition compared to the precursor material can be at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 90% at least about 95% on a dry weight basis.

[0229] Example 1 In a first test, the precursor material consisted essentially of an aqueous tobacco extract and glycerol. The aqueous tobacco extract was further diluted with glycerol to about 24% by weight (calculated on a dry weight basis). The aqueous burley tobacco extract had a tobacco solids content of about 40% by weight and a moisture content of about 60% by weight. The precursor material was dried by freeze drying.

[0230] Example 2 In further tests, the precursor material consisted essentially of aqueous tobacco extract, glycerol and dextran 70. The glycerol content was from about 0 to about 15% v / v, or up to about 36% by weight, calculated on a dry weight basis. The precursor material was dried by lyophilization.

[0231] Example 3 The freeze-dried material of Example 1 or Example 2 is milled to obtain a loose powder having an average size of about 10 μm to about 50 μm. 50 mg of the powder is then placed into a fleece pouch to provide an oral product for releasing flavors and / or actives upon contact with the salvia in the user's oral cavity.

[0232] Example 4 The lyophilized aerosol generating material of Example 1 or Example 2 is ground to obtain a loose powder having an average size of about 500 μm to about 1000 μm. 200 mg of the powder is then placed into a permeable pod with a susceptor containing a metal mesh to provide a consumable for use in an aerosol generating system that provides aerosol for a series of puffs or a session of puffs.
