TOBACCO MOUSSE
Summary [0001] The present invention relates to a foam comprising an inhalable agent and / or agent containing tobacco ingredient, an aerosol forming agent, a foam stabilizing agent and a foaming agent.
Background of the Art [0002] Foam tobacco products were known in the prior art mainly in the field of reconstituted tobacco products. Manufacturing processes generally involve forming reconstituted tobacco leaves from finely molded tobacco particles with a foaming agent and a foam stabilizing agent, followed by crushing the reconstituted leaves and mixing with pieces of natural tobacco. Reconstituted tobacco products are generally used to make cigarettes.
[0003] For example, tobacco foams are used to produce reconstituted tobacco, as disclosed, for example, in US 4002178 A, in which the precursors glycerin and propylene glycol are used in an amount of less than 5% and tobacco in about 70%. US7500485B1 describes a foam tobacco composition in which the amount of tobacco is about 40% by weight.
[0004] However, these foams are intended for combustion use instead of tobacco using reconstituted tobacco.
[0005] In addition, foams that comprise tobacco that

are used for combustion, this is, burn, are revealed in US 7500485 Bl, US 2016/28 6851 Al e US 2011/088708 Al.[0006] 0 US document 7500485 Bl se refers to an composition foam tobacco what includes particles in tobacco, water and a stabilizer foam which is one
hydrophobically modified hydroxyalkylated carbohydrate, as well as its use in a low density tobacco leaf material that can then be used to produce filler materials in cigars, cigarettes or pipes.
[0007] US 2016/286851 A1 discloses a smoke composition comprising an aerosol-forming substrate and an aroma precursor compound.
[0008] US 2011/088708 A1 describes smokable filler materials and a process for producing them, wherein the smokable filler material comprises a foaming agent, an agent capable of forming chemical cross-links and a cross-linking agent.
[0009] The spread and popularity of electronic cigarettes (e-cigarettes) arose with the need and possibility for innovative tobacco products to be vaporized and inhaled by smokers. E-cigarettes or similar devices such as electronic pipes generally generate an aerosol by heating a liquid that comprises an additional aerosol-forming agent, water and optionally flavoring and nicotine. In general, this can lead to an uneven smoke profile, in which the experienced aroma of puffs can differ significantly, for example, by an inefficient extraction of key compounds in the liquid.

[0035] As used herein,% by weight should be understood as the percentage by weight, based on the total weight of the foam, unless explicitly specified otherwise. In the present disclosure, all amounts are given in% by weight, unless clearly stated otherwise or obvious from the context. In the present disclosure, moreover, all amounts given in% by weight in a particular foam add up to 100% by weight. Weight percentages are thus calculated by dividing the mass of each component by the total mass of the foam, unless otherwise stated or clear from the context.

According to certain embodiments, no water and / or acid and / or ester, for example, diacetin, or at least below 1% by weight, is contained in the present foam. In firing applications, for example, smoking articles, water is usually contained in larger quantities, since dry smoke does not taste so pleasant. In contrast, the present foams are particularly unburnt, and the aerosol-forming agent can carry aromas and / or flavors, so that the amount of water can be kept low, although some small amounts of water can help to reduce any roughness. steam and allow a smoother smoking experience. Similarly, the addition of a small amount of diacetin (preferably less than 1% by weight) can also reduce any roughness in the aerosol produced as experienced by users.
[0039] Also disclosed in a second aspect is a foam consisting essentially of an inhalable agent and / or agent containing tobacco ingredient, an aerosol forming agent, a foam stabilizing agent and a foaming agent. Small amounts of water and / or acid and / or ester, eg diacetin, up to 5%

11/54 by weight, preferably up to 3.5% by weight, more preferably up to 2.5% by weight, even more preferably up to 1.5% by weight, can be contained in the foam according to the second aspect of the invention.
[0040] According to certain modalities, the foam may consist of an inhalable agent and / or agent containing tobacco ingredient, an aerosol forming agent, a foam stabilizing agent and a foaming agent. In such a modality, of course, unavoidable impurities may be contained.
[0041] A third aspect of the invention relates to a foam comprising: an inhalable agent and / or agent containing tobacco ingredient, an aerosol forming agent, a foam stabilizing agent and a foaming agent, wherein the foaming agent is a protein-free polysaccharide, and the weight of the foaming agent is less than 20% by weight of the foam. According to certain embodiments of the foam of the third aspect, the weight of the inhalable agent and / or the agent containing tobacco ingredient is 0.1 - 40% by weight, preferably 0.1 - 33% by weight of the foam, and / or the weight of the aerosol forming agent is 1080% by weight, preferably 40 - 70% by weight, of the foam weight.
[0042] The present foams, that is, of the first, second and third aspects, can be - according to certain modalities - configured to be heated, but not burnt, that is, they are used in an application in which they are not smoked. Thus, a use of the present foams as articles that are not
Petition 870190060453, of 06/28/2019, p. 20/79
12/54 burned, and their use in non-smoking applications, for example, for evaporation devices such as e-cigarettes, e-pipes and similar devices. The first, second and third aspect foams can be used in a vaporizer device comprising a heater to heat the foam to a temperature of maximum 350 ° C, preferably maximum 300 ° C, more preferably below 300 ° C and, most preferably, between 220 ° C and 270 ° C.
[0043] In the following, the description refers to foams from the first to the third aspects, unless it is clear, from the context, that it is otherwise.
[0044] The present foams are preferably non-smokable, that is, they are applied in a way that they are not heated to a temperature at which they are burned, but only at least parts of them are evaporated, particularly at least essentially the aerosol formation and more preferably at least a part of the inhalable agent and / or the agent containing tobacco ingredient, more preferably also essentially the inhalable agent and / or agent containing tobacco ingredient. In the present foams, at least some parts of the inhalable agent and / or the agent containing tobacco ingredient are preferably adhered to the foam structure and / or absorbed by the foam structure formed essentially by the foaming agent and the stabilizing agent. foam, so that they can be easily released together with the aerosol forming agent after heating. In addition, it is possible that some parts of the inhalable agent and / or the
Petition 870190060453, of 06/28/2019, p. 21/79
13/54 agent containing tobacco ingredient are attached to the foam structure, and the inhalable agent and / or agent containing tobacco ingredient are extracted during heating, so that an aroma of the inhalable agent and / or agent that contains tobacco ingredient to be released from them together with the aerosol forming agent. According to certain embodiments, the inhalable agent and / or agent containing tobacco ingredient is configured so that it is released after heating together with the aerosol forming agent and is only essentially adsorbed and / or absorbed in the foam structure. In this regard, the inventors have shown that a loss of mass in the foam can be observed which shows that essentially at least the mass of the foaming agent and the foam stabilizing agent remains. The foam structure is presumed to be mainly formed by the foaming agent, which forms a cap to adhere and / or absorb the aerosol forming agent and an inhalable agent and / or the agent containing tobacco ingredient, while whereas the foam stabilizing agent stabilizes the foam to maintain the shape of the foam.
[0045] According to certain embodiments, only a small amount or essentially no amount, for example, no amount, of the aerosol forming agent takes part in the foaming, that is, it is bound within the foam. The aerosol forming agent preferably does not form the foam structure and, most preferably, is adhered to the foam structure and / or included in the foam structure,
Petition 870190060453, of 06/28/2019, p. 22/79
14/54 for example, trapped in pores thereof at room temperature, for example, from 0 to 40 ° C, for example, room temperature from about 20 to about 25 ° C.
Thus, according to certain modalities, the present foams will undergo significant weight loss due to the aerosol forming agent, at least after heating to a temperature at which the aerosol forming agent is evaporated, for example , at a temperature that is at least as high as the highest boiling point of all aerosol forming agents contained, but preferably below a temperature at which the foam is burned. Therefore, the invention also relates to a foam that results from heating the foam of the first and / or second and / or third aspects, particularly at a temperature that is at least as high as the highest boiling point of all agents. aerosol forming agents contained, but preferably below a temperature at which the foam is burned, wherein particularly at least 40% by weight, preferably at least 45% by weight, more preferably at least 50% by weight, particularly preferably at least 60% by weight of the weight of the unheated foam is lost after heating.
[0047] Furthermore, the foams are not - according to certain modalities - connected and / or connected to a carrier, that is, they can be used as they are, that is, as an independent foam. In particular, the foams are not bound to a substrate, according to certain modalities, but are used as they are. Thus, according to certain modalities, the present foams
Petition 870190060453, of 06/28/2019, p. 23/79
15/54 are stable enough to be used as they are, that is, they are self-supporting, and have sufficient stiffness, so that they are not bent when collected by themselves and do not require an additional stabilizing substrate.
[0048] According to certain modalities, the present foams are biodegradable.
[0049] The following description refers to the foams described above in the first, second and third aspects of the invention and thus applies to each of these. All present foams can be, for example, in the form of a mousse.
[0050] The foam structure in the foams is not particularly limited and can, for example, comprise trapped air bubbles and / or bubbles of other gases, such as nitrogen or oxygen, for example, air bubbles. It can be supplied as an open structure with a large surface area, which allows heat and aerosol to circulate through the foam, particularly during heating, thus providing uniform heating, a good quality aerosol and extremely efficient extraction. inhalable agent and / or agent containing tobacco ingredient. According to certain modalities, the foam is an open pore foam. It can be a liquid foam, a dry foam, a solid foam, or a pellet, preferably a dry foam, a solid foam or a pellet. The foaming agent can generally trap the bubbles when the foam is formed, for example, whipped, and the foam stabilizing agent can reduce and even prevent foam breakage. The foam bubbles can have an average diameter in the range of 20 - 120 pm, for
Petition 870190060453, of 06/28/2019, p. 24/79
16/54 example, 50 - 100 pm, for example, 60 - 80 pm, and about 98% of the bubbles can have a diameter of 160 pm or less, for example, 140 pm or less, for example, 120 pm or less . The foam can be formed in any shape suitable for insertion into an e-cigarette. According to certain embodiments, the present foam comprises at least one tipper or hole through the foam for the circulation and aerosol transmission, for example, one, two, three, four, five, six, seven, eight, nine, ten or more holes through the foam. An exemplary shape is an annular tube shaped hole that extends through the foam portion of any shape, for example, about 1 cm in diameter, for example, a 3 mm through hole, or a square, a star , but it can also be any other shape or dimension. According to certain embodiments, the foam has a structure that has a large surface area, for example, that has at least one surface with at least one distance between any two sides of the surface or with a diameter that is sufficiently larger than the foam thickness. The foam can thus be shaped like a disk, for example, a cylindrical disk, a thin plate, etc. According to certain embodiments, the at least one hole extends through at least one surface with at least one distance between any two sides of the surface or with a diameter that is sufficiently greater than the thickness of the foam.
[0051] The agent containing tobacco ingredient, for example, tobacco, can be used to provide authentic aroma, and is not particularly limited. According
Petition 870190060453, of 06/28/2019, p. 25/79
In certain embodiments, the tobacco-containing agent of the present foam is at least one selected from the group consisting of tobacco, tobacco flavor, such as various tobacco extracts, and nicotine or a derivative thereof. The tobacco, tobacco flavor and / or nicotine can be derived from any part of the tobacco plant (seed, stem, leaf and so on).
[0052] Similarly, the inhalable agent is not particularly limited and can be, for example, at least one among a stimulant, for example, caffeine, guarana and combinations thereof, and / or a flavor, for example, menthol, vegetable aromas natural and / or artificial, for example, flavorings known for use in conventional e-liquids for use with e-cigarettes that vaporize e-liquid, for example, in the amounts used in them, saccharides, animal aromas and combinations thereof.
[0053] The inhalable agent and / or agent containing tobacco ingredient are preferably comprised in the present foam in an amount of 0.1 to 40% by weight, more preferably 0.1 - 33% by weight of the foam. If the amount of tobacco is increased to above 40% by weight, particularly above 33% by weight of the foam, for example, at the expense of the stabilizing agent, the foam, for example, in a mousse, can become too fragile and unstable. In addition, if the amount of the inhalable agent and / or the agent containing tobacco ingredient is increased above that amount, the amount of the aerosol forming agent can be reduced, which can cause an amount
Petition 870190060453, of 06/28/2019, p. 26/79
Lower 18/54 aerosol TPM (total particulate matter, which is the amount of aerosol matter retained in a filter by user inhalation). In certain embodiments, the amount of inhalable agent and / or tobacco ingredient agent comprised in the foam is 1 - 30% by weight of the foam, preferably 3-29% by weight, more preferably 5-28% by weight, more preferably 10-28% by weight, even more preferably 11 to 27.5% by weight, for example, 15 to 25% by weight, for example, 11-23% by weight, for example, 17-21% by weight .
[0054] According to certain embodiments, the tobacco ingredient-containing agent comprises tobacco particles which have a particle size of less than 200 pm, preferably less than 150 pm, more preferably less than 100 pm, even more preferably less than 50 pm, preferably until less than 30 pm, for example, 2-150 pm, for example, 5-100 pm, for example, 5-50 pm, for example, 5-30 pm, for example, 5-15 pm , for example, 20 50 pm, for example, 60-90 pm. The particle size can be measured through sieving, and the particles can be obtained through any suitable grinding and / or grinding process. According to certain embodiments, the tobacco particles are essentially uniform in size, for example, uniform in size.
[0055] No however, also is possible add particles of tobacco with sizes many different in two or more fractions, per example, an first fraction with particles that has one size in less than 30 pm, per example, less in 20 pm, and an l second fraction with particles that has one size in more of 30 pm, per

19/54 example, more than 50 μη, for example, more than 100 μη, for example, more than 200 μη, for example, about 250 μη or more. Preferably, for example, a second fraction of tobacco particles with a size of more than 30 μη is contained in a mixture of tobacco particles with sizes
different in one amount in any less out of 9 ( 3% in Weight, preferably 80% in Weight, or any less, more preferably any less in 50 % in Weight, still more preferably any less in 40 % in Weight, still more preferably any less in 30 % in Weight, still more preferably 2 0% on weight or less , with based on Weight
total tobacco particles. An addition of tobacco particles with a size of more than 30 μη can lead to a reduction in the roughness of the aerosol released from the foam after heating in the first puffs.
[0056] In the present method, the foam stabilizing agent is not particularly limited, in that it can stabilize the foam to some extent after formation. According to certain modalities, the foam stabilizing agent of the present foam is selected from the group consisting of cellulose gum, hydroxyalkylated carbohydrates, derived from them, for example, salts thereof, preferably alkali metal salts thereof, for example, sodium and / or potassium salts thereof and mixtures thereof. Neither cellulose gum nor hydroxyalkylated carbohydrates are particularly restricted. According to certain preferred embodiments, the foam stabilizing agent is a cellulose gum, particularly a carboxymethyl cellulose, or a derivative thereof. A gum of
Petition 870190060453, of 06/28/2019, p. 28/79
Exemplary preferred cellulose that can be used in the present invention is CEKOL® 2000, a purified sodium carboxymethyl cellulose. Another class of suitable foam stabilizing agents are hydroxyalkylated carbohydrates and, more preferably, cellulose ethers and derivatives thereof. A cellulose ether or derivative thereof that can be used can have at least one substituent selected from the group consisting of methyl, ethyl, hydroxyethyl and hydroxypropyl groups. It can additionally be substituted by substituted or unsubstituted straight or branched alkyl radicals having 1 to 20 carbon atoms or an aralkyl radical having 7 to 20 carbon atoms. Such a radical is preferably joined by an ether bond. Suitable substituents can be, for example, a hydroxy group, a carboxy group with 1 to 4 carbon atoms, etc. According to certain modalities, cellulose ether is selected from hydroxyethylcellulose, methylcellulose, methylhydroxyethylcellulose, ethylhydroxyethylcellulose and mixtures thereof. In addition, mixtures of different cellulose gums, different hydroxyalkylated carbohydrates and mixtures of one or more cellulose gums with one or more hydroxyalkylated carbohydrates, as well as derivatives of one or any of the same, may be used. Also included as derivatives are salts of these cellulose ethers, preferably alkali metal salts thereof, for example, sodium and / or potassium salts thereof.
[0057] The amount of the foam stabilizing agent in the foam is not particularly limited, as it
Petition 870190060453, of 06/28/2019, p. 29/79
21/54 a suitable stable foam can be formed. For example, the foam stabilizing agent can be contained in an amount of 3 - 60% by weight, preferably 4-50% by weight, more preferably 4-45% by weight, more preferably 4.2 - 40% by weight , more preferably 4.5 - 20% by weight, even more preferably 5-20% by weight, even more preferably 5.5 - 16% by weight, for example, 8-40% by weight, for example, 12-30 % by weight, for example, 16-20% by weight.
[0058] The foaming agent is also not particularly restricted. According to certain modalities, the foaming agent of the present foam is selected from the group consisting of agar, gum gum, lecithin, polyglycerol esters of fatty acids, glycerol esters of fatty acids, sorbitan esters of fatty acids and / or mixtures thereof, without being limited to them. A preferred foaming agent is gellan gum. Particularly proteoglycans, but also pectin and alginates, have been shown to be less suitable as foaming agents. The fatty acids therein are not particularly limited and can comprise, for example, 8-40 carbon atoms. Glycerol esters can be prepared by standard esterification methods. If glycerol esters of fatty acids are used, the foaming agent may suitably be a compound such as glycerol monostearate and / or glycerol mono-oleate. Polyglycerol esters can be prepared by polymerizing glycerin under alkaline conditions
Petition 870190060453, of 06/28/2019, p. 30/79
22/54 properly followed by their reaction with specific fatty acids. Suitable polyglycerol esters can be hexaglycerol mono-oleate, octaglycerol mono-stearate and / or octaglycerol mono-oleate. The fatty acid sorbitan esters used in certain embodiments of the present invention can be sorbitan monostearate, sorbitan mono-oleate and / or sorbitan mono-palmitate. In addition, any possible combinations of compounds that belong to the classes mentioned above can be used.
[0059] And choosing adequate amounts of foaming agent and foam stabilizing agent together with the inhalable agent and / or agent containing tobacco ingredient can create and stabilize the foam matrix, which can contribute to the hardness of the foam.
[0060] Like the foam stabilizing agent, the amount of the foaming agent is not particularly limited, as a foam is formed. For example, the foaming agent may be contained in an amount of 0.5-12% by weight, preferably 1-11% by weight, more preferably
1.5-10% by weight, more preferably 1.8 - 9.5% by weight, more preferably 2-9% by weight, even more preferably 2-7% by weight, particularly preferably 2.25 - 6, 75 % by weight, for example, 5.5% by weight.
[0061] Furthermore, the aerosol forming agent is also not particularly limited, and the foam may also comprise more than one aerosol forming agent, for example, two, three or four, for example,
Petition 870190060453, of 06/28/2019, p. 31/79
23/54 in the form of a mixture.
[0062] According to certain modalities, the aerosol forming agent of the present foam is selected from the group consisting of glycerol, glycol derivatives, sebacate esters and / or mixtures thereof, without being limited to them. A glycol derivative that can be used in certain embodiments is propylene glycol, and a suitable sebacate ester can be di-2-ethylhexyl sebacate. In addition, any possible combinations of compounds that belong to the classes mentioned above can be used. For example, a combination of glycerol and propylene glycol can be used as an aerosol forming agent. Preferred examples of the present aerosol forming agent are glycerol, propylene glycol and mixtures thereof, with glycerol and a more preferred mixture of propylene glycol and glycerol and an even more preferred mixture of propylene glycol and glycerol. According to certain embodiments, at least glycerol is understood as an aerosol forming agent. According to certain modalities, glycerol and propylene glycol can be used with equal weight percentages, but also with different weight percentages. In certain embodiments, 10-95% by weight of glycerol and 5-90% by weight of propylene glycol, preferably 10-80% by weight of glycerol and 20 - 90% by weight of propylene glycol, more preferably 10-70% by weight. weight of glycerol and 70 -10% by weight of propylene glycol, for example, 15-65% by weight of glycerol and 65-15% by weight of propylene glycol, preferably 20 - 40% by weight of glycerol and 10-40% by weight of propylene glycol, for example, 20 - 40% by weight
Petition 870190060453, of 06/28/2019, p. 32/79
24/54 glycerol and 20 - 40% by weight of propylene glycol can be used as an aerosol forming agent, wherein the total mass of the aerosol forming agent is 10 to 80% by weight, preferably 40 - 70% by weight of the weight of the foam, so that the two components can be properly adjusted in relation to their ratio. However, according to certain modalities, glycerol is used as the only aerosol forming agent.
[0063] A suitable ratio of propylene glycol and glycerol is, according to certain modalities, in a mixture that comprises these two as an aerosol forming agent or that consists of these two as an aerosol forming agent, according to preferred modalities, between 8: 1 and 1: 8, preferably between 80:20 and 20:80, more preferably between 4: 1 and 1: 4, more preferably between 70:30 and 30:70, even more preferably between 1: 2 and 2 : 1, for example, between 60:40 and 40: 60, for example, between 55:45 and 45: 55, based on a weight ratio. According to certain embodiments, glycerol is used in an excessive amount compared to propylene glycol if both are used as a mixture for an aerosol forming agent or are particularly used as an aerosol forming agent. According to certain embodiments, glycerol is used in an amount of at least 55% by weight, preferably at least 60% by weight, based on the total amount of glycerol and propylene glycol in the aerosol forming agent. Consequently, according to certain modalities, propylene glycol is used in an amount of a maximum of 45% by weight, preferably
Petition 870190060453, of 06/28/2019, p. 33/79
25/54% by weight or less, based on the total amount of glycerol and propylene glycol in the aerosol forming agent. According to certain modalities, the ratio between glycerol and propylene glycol is between 20:80 and 90:10, preferably between 40:60 and 85:15, more preferably between 55:45 and 80:20, even more preferably between 60: 40 and 80:20, for example, about 60:40, for example, 60:40, based on the total amount of glycerol and propylene glycol in the aerosol forming agent. The ratio of propylene glycol to glycerol can influence the basic viscosity of the foam. A higher amount of glycerol leads to a higher viscosity and a better texture of the foam, for example, a mousse and allows a better release of the inhalable agent and / or the agent containing tobacco ingredient, leading to a better body for inhalation due to a better mix. In addition, a greater amount of glycerol can lead to a decreased level of steam initially created after heating, which can have an influence on the harshness of the steam felt after inhalation. At the same heating temperature, glycerol can also release less volume of vapor than propylene glycol if the heating is above the boiling point of both. A greater amount of propylene glycol leads to a higher sweet note during inhalation, especially if 10% by weight or more, preferably 20% by weight or more, for example, 20 to 40% by weight, or more than 20% by weight, more than 30% by weight, or more than 40% by weight of the total aerosol / wetting agent comprises propylene glycol instead of glycerin.
Petition 870190060453, of 06/28/2019, p. 34/79
26/54 [0064] The aerosol forming agent is comprised in an amount of 10 to 80% by weight, preferably 20 to 75% by weight, more preferably 40 - 70% by weight, more preferably 45 - 70% by weight , more preferably 45 - 65% by weight, particularly preferably 50 - 63% by weight, more preferably 55 to 65% by weight, for example, about 60% by weight of the foam, which is much higher than the prior art in with respect to reconstituted tobacco foams, how an aerosol should be formed. This may, for example, enable a more convenient foam-making process than in the prior art. If the amount of aerosol forming agent is too high, however, no foam will be formed, but creamy liquid fluid. If the amount of aerosol forming agent is too low, no foam will be formed, but a paste particularly without a foam structure, particularly bubbles and / or pores.
[0065] Propylene glycol, as used in the present invention, is to be understood as propane-1,2-diol. Glycerin or glycerol, as used in the present invention, is to be understood as 1,2,3-propanotriol.
[0066] The aerosol forming agent may additionally comprise water. According to certain modalities, no water is contained, however, since water in aerosol form can burn a user's mouth. The water can be contained in an amount of 0 15% by weight of the foam weight, for example, 5 - 10% by weight. Small amounts of water and / or an acid and / or ester, for example, diacetin, particularly water and / or
Petition 870190060453, of 06/28/2019, p. 35/79
27/54 ester, for example, diacetin, up to 5% by weight, preferably up to 3.5% by weight, more preferably up to 2.5% by weight, even more preferably up to 1.5% by weight and most preferably , between 0.5 - 1.5% by weight, at least between 0.5 - 1.5% by weight of water, can be contained in the foam. According to certain embodiments, no water and / or acid, particularly no water and / or ester, for example, diacetin, is contained in the present foam. If an ester, for example, diacetin, is included, it is preferably included with 3% by weight or less, preferably 2% by weight or less, more preferably 1.5% by weight or less, for example, 1% in weight or less.
[0067] According to certain modalities, the present foams may additionally comprise at least one non-smoking flavoring agent. In certain modalities, the aromas can be selected from menthol, natural vegetable aromas, for example, cinnamon, sage, forage, chamomile, kudzu (Pueraria lobata), hydrangeae dulcis folium, clover, lavender, cardamom, caryophyllus, nutmeg , bergamot, geranium, honey essence, rose oil, lemon, orange, cassia peel, cumin, jasmine, ginger, coriander, vanilla extract, mint, mint, cassia, coffee, celery, cascarilla, sandalwood, cocoa, ylang ylang, fennel, anise, licorice, St. John's bread, plum extract and peach extract; saccharides, for example, glucose, fructose, isomerized saccharide and caramel; cocoa, for example, powder and extract; esters, for example, isoamyl acetate, linalyl acetate, isoamyl propionate and linalyl butyrate; ketones, for
Petition 870190060453, of 06/28/2019, p. 36/79
28/54 example, mentone, ionone, damascenone and ethyl maltol; alcohols, for example, geraniol, linalool, anethole and eugenol; aldehydes, for example, vanillin, benzaldehyde and anisaldehyde; lactones, for example, γ-undecalactone and γ-nonalactone; animal aromas, for example, musk, amber, civet and castoreal; and hydrocarbons, for example, limonene and pinene and combinations thereof, without being limited to them. This aroma or others can be used alone or in combination. The non-tobacco flavoring agent may, for example, be added in an amount such that the total quantity of the agent containing tobacco ingredient and the non-tobacco flavoring agent, if these two are included, add up to the quantities given to the agent containing tobacco ingredient given above.
[0068] In certain embodiments, the foams may comprise an electrically conductive material and, more particularly, a ferromagnetic material, to generate heat by induction. The electrically conductive material is not particularly limited and can be any of, or alloys of, iron, nickel, stainless steel, manganese, silicon, carbon and copper. The electrically conductive material may be in the form of a powder and / or larger particles. Its quantity is not particularly restricted and can be adjusted accordingly.
[0069] The present foams can, for example, be formed on a disk, foam tube etc., optionally with one or more tunnels and / or holes for the air flow, and a foam rod etc. for example, it can be cut into capsule-shaped pieces to be placed in a capsule.
Petition 870190060453, of 06/28/2019, p. 37/79
29/54 [0070] In another embodiment, the foams can be arranged as a capsule, disc or rod, and can be packed in a porous paper, for example, with a filter on the tip next to the user. The porous paper is not particularly limited and can be made of wood pulp and / or hemp fibers or combinations thereof. The filter material of the filter is not particularly limited and may be any filament material conventionally employed for the manufacture of tobacco smoke filter. The filter material can be a natural or synthetic filament bundle, for example, of cotton or plastics, such as polyethylene or polypropylene, or cellulose acetate filament bundle.
[0071] The present foams can be sold in packages, for example, a hermetically sealed wrapper, which can, for example, be removed by the user or perforated by the e-cigarette when operationally housed. Another example can be a blister pack containing one or more foam units, together or separated, for example, separated, that is, in separate packaging units that can be opened separately. According to certain modalities, the packaging at least prevents water from coming into contact with the present foams.
[0072] A peripheral support material, for example, metal or other inert material for heat transmission can surround the present foam. In an example of annular ring foam, the support material can be a metal ring disposed, for example, around the side of the annular space. The support material may have openings for circulation.
Petition 870190060453, of 06/28/2019, p. 38/79
The present foams can form an aerosol after being subjected to a temperature of 150 - 350 ° C, for example, 200 - 300 ° C, preferably at least above a boiling point of a aerosol, for example, at least to the boiling point of the aerosol forming agent with the highest boiling point, but at a temperature below which the foam is burned. The heat can be supplied by any suitable heat source, such as an electric heater or other suitable heat generating device, which is not particularly limited. If the temperature is too low, the evaporation of the aerosol-forming agent in the foam will be insufficient, leading to insufficient aerosol. If the temperature is too high, there is a risk that the aerosol formed is too hot and that the foam may burn.
[0074] According to certain embodiments, foams include a porous structure that has open pores, particularly where the structure is essentially formed from the foaming agent and the foam stabilizing agent.
[0075] According to certain modalities, the aerosol forming agent and / or an inhalable agent and / or the agent containing tobacco ingredient and / or the at least one ideal non-smoking flavoring agent is, at least to some extent adhered to the foam structure and / or absorbed in the foam structure and, in particular, the aerosol forming agent and / or an inhalable agent and / or the agent containing tobacco ingredient and / or at least one flavoring agent not ideal tobacco is essentially
Petition 870190060453, of 06/28/2019, p. 39/79
31/54 adhered to the foam structure and / or absorbed in the foam structure. In this way, these components can be easily released after heating, particularly together with the aerosol forming agent.
[0076] According to certain modalities, the present foams additionally comprise a solvent and / or an acid and / or an ester in an amount of up to 15% by weight, based on the total weight of the foam, preferably up to 5% by weight , as already discussed above.
[0077] According to certain modalities, the solvent and / or acid and / or ester are comprised in an amount of up to 15% by weight before any drying stage, based on the total weight of the foam, preferably up to 5% in Weight. The water can be contained in an amount of 0 - 15% by weight of the foam weight before any drying stage, for example, 5
- 10% by weight. Small amounts of water and / or an acid and / or ester, eg diacetin, particularly water and / or ester, eg diacetin, up to 5% by weight, preferably up to 3.5% by weight, more preferably up to 2.5% by weight, even more preferably up to 1.5% by weight, and most preferably between 0.5 - 1.5% by weight, at least between 0.5
- 1.5% by weight of water, can be contained in the foam before any drying stage. According to certain embodiments, no water and / or acid, particularly no water and / or ester, for example, diacetin, is contained in the present foam before any drying stage. If an ester, for example,
Petition 870190060453, of 06/28/2019, p. 40/79
32/54 diacetin, is included, it is preferably included with 3% by weight or less, preferably 2% by weight or less, more preferably 1.5% by weight or less, for example, 1% by weight or less before any drying stage.
[0078] The present invention also relates to a method of generating an aerosol, the method comprising heating a foam comprising an agent containing tobacco flavor, an aerosol forming agent, a foam stabilizing agent and a foaming agent, particularly the foam of the first and / or second and / or third aspects of the invention, in the absence of combustion at 150 - 350 ° C, for example, 200 - 300 ° C. A method of generating an aerosol can, for example, be performed with the foam of the present invention.
[0079] In certain embodiments, the present foam may comprise tobacco, optionally nicotine and optionally at least one additional flavor. In other certain embodiments, it may comprise nicotine and optionally at least one additional flavor. In yet another embodiment, it may comprise only tobacco flavoring as the agent containing the tobacco ingredient. In yet another embodiment, it may comprise only at least one inhalable agent and optionally at least one additional flavor.
[0080] The present invention also relates to an aerosol obtainable by heating the present foams in the absence of combustion. An absence of combustion in this document means heating to a temperature that is below the combustion temperature of the components of the
Petition 870190060453, of 06/28/2019, p. 41/79
33/54 foam, which generate the aerosol, or even below the combustion temperature of all foam components. Such a temperature can be, for example, 350 ° C or less, for example, 150 - 350 ° C, for example, 200 - 300 ° C.
[0081] The aerosol can be released by heating the foam. The aerosol forming agent can be mixed with the inhalable agent and / or agent containing tobacco ingredient and optionally one or more flavors and / or additional extracts of the inhalable agent and / or agent containing tobacco ingredient. When the aerosol-forming agent is heated and vaporized, the vapor may be carrying the agent containing tobacco ingredient and / or the bound inhalable agent and / or one or more compounds extracted from the inhalable agent and / or agent containing ingredient tobacco and optionally one or more additional flavors.
[0082] A (first) foaming method is also disclosed which comprises mixing an aerosol forming agent, a foaming agent and optionally a solvent, which is not particularly limited, and can comprise, for example, purified water, an acid and / or ester, for example diacetin, and / or an alcohol such as ethanol, 1-propanol and / or 2-propanol, or mixtures thereof, under heating, optionally injecting or circulating in a gas, for example, during heating, where the gas may be, for example, air, oxygen, nitrogen, or mixtures thereof, add an agent containing tobacco ingredient and / or the inhalable agent, add a foam stabilizing agent and cool the mixture.
[0083] In addition, a (second) foaming method is disclosed, which comprises mixing an agent
Petition 870190060453, of 06/28/2019, p. 42/79
34/54 aerosol formation and optionally a solvent, under heating; adding an inhalable agent and / or agent containing tobacco ingredient to the mixture; add a foaming agent; optionally inject a gas; add a foam stabilizing agent; and cooling the mixture, wherein preferably the foam stabilizing agent is added after the foaming agent, aerosolizing agent, the optional solvent and an inhalable agent and / or the agent containing tobacco ingredient.
[0084] With the present methods, particularly the foams of the first and / or second and / or third aspects of the invention can be produced. Therefore, the aerosol forming agent, the foaming agent, the foam stabilizing agent, the inhalable agent and / or agent containing tobacco ingredient can be chosen as indicated above in relation to the foams of the invention, as well as the amounts each of them. In addition, at least in non-tobacco flavoring agent and / or an electrically conductive material and / or other optional ingredients can be suitably added, as indicated above, in relation to the present foams.
[0085] According to certain modalities, the step of mixing an aerosol forming agent, optionally a foaming agent - in the first method - and optionally a solvent under heating is performed first. According to certain embodiments, the foaming agent is then added to the aerosolizing agent in the first method, particularly when the aerosolizing agent
Petition 870190060453, of 06/28/2019, p. 43/79
35/54 comprises more than one component, for example, propylene glycol and glycerol. In the second method, the foaming agent is preferably added after the agent containing tobacco ingredient and / or inhalable agent, particularly when the agent containing tobacco ingredient and / or inhalable agent can be dissolved in the aerosolizing agent and in the optional solvent and / or when they do not bind to the foam structure, that is, they are only adhered / adsorbed to it and / or absorbed in it. When the foaming agent is added, the viscosity can be increased, and a microstructure with bubbles, for example, in the presence of air, an aerated microstructure, can be formed, which allows a constant aerosol release of the foam after the heating, as well as the release of a consistent volume of steam. In the second method, then, also the agent containing tobacco ingredient and / or inhalable agent can then be contained in the microstructure and be released effectively after heating, leading to a constant vapor flow and stable aroma perception.
[0086] In the first method, the agent containing tobacco ingredient and / or inhalable agent are preferably added after the foaming agent. In this case, the agent containing tobacco ingredient and / or inhalable agent can be equally distributed and allows for a constant release of aroma and perception of stable aroma. This method is particularly suitable if the agent containing tobacco ingredient and / or inhalable agent is at least partially participating in the foaming.
Petition 870190060453, of 06/28/2019, p. 44/79
36/54 [0087] In certain embodiments, the mixture can be heated to 30 - 80 ° C, for example, to 45 - 75 ° C during the mixing of an aerosol forming agent, a foaming agent and optionally a solvent. Heating can, for example, assist dispersion, for example, by lowering viscosity.
[0088] If water and / or an acid and / or ester, for example, diacetin, are added as a solvent and / or additive, they are preferably added in an amount of up to 5% by weight, preferably up to 3.5% by weight, more preferably up to 2.5% by weight, even more preferably up to 1.5% by weight, based on the weight of the resulting foam. This allows for better handling and in particular also makes drying easier and, according to certain modalities, even unnecessary. If an ester, for example, diacetin, is added, it is preferably included with 3% by weight or less, preferably 2% by weight or less, more preferably 1.5% by weight or less, for example, 1% in weight or less, for example, less than 1% by weight.
[0089] According to certain modalities, the foaming agent is added last, that is, after the aerosol forming agent, the foaming agent, the inhalable agent and / or agent containing tobacco ingredient , the optional solvent and other optional ingredients. The optional solvent and other optional ingredients can be added in a suitable step, for example, together with the inhalable agent and / or agent containing tobacco ingredient.
[0090] The final addition of the stabilizing agent of
Petition 870190060453, of 06/28/2019, p. 45/79
37/54 foam leads to a stable formation of the foam matrix. This allows for an adequate release of aerosol and aroma-forming agents, thus enabling better handling and particularly maintaining volatile components in the foam matrix. During heating, at least the foaming agent and the foam stabilizing agent remain as a disposable wrap - after foaming and evaporation of the aerosolizing agent and at least aromas and / or flavors of the inhalable agent and / or the agent containing the tobacco ingredient.
[0091] In certain modalities, the mixture can be cooled to room temperature and below, for example
example, 15 - 25 ° C, for example, about 20 ° C, or below, per example, less than 20 ° C or up to less than 10 The z — iC, for example of a quick way, for example, in less than 20 minutes, for example, 15 minutes or less, per example, 10 minutes or less. According certain
modalities, the foam can be aged for 4-24 hours, for example, 12-24, or, for example, 6-8 hours, and / or at a temperature of 35 - 60 ° C, for example, 40 - 55 ° Ç. The mixing and addition of components in this method are not particularly limited and can be properly performed by known methods. In certain embodiments, the steps in the foaming method can be carried out in order, as indicated above, for the respective method. With the present methods, particularly the foam of the present invention can also be obtained. Thus, according to certain modalities, the different compounds can be added properly
Petition 870190060453, of 06/28/2019, p. 46/79
38/54 in an amount such that the present foam is obtained. The corresponding quantities are already mentioned in relation to the present foam.
[0092] The present invention also relates to an aerosol generating system, which comprises the present foam and an aerosol generating apparatus, for example, the foam as defined above. In the aerosol generating system, the aerosol generating apparatus is not particularly limited. In certain embodiments, the aerosol generating device can be any type of e-cigarette or similar devices such as an electronic pipe. The same can, for example, comprise a heating system, which is not particularly limited and can be an electrically heated system or an induction heating system, a control system for controlling the heating system, a receiving portion for receiving the foam and to transmit heat to the foam, without combustion of the foam, and a flow path through the inhalation device to transmit aerosol from the receiving portion, for example, a capsule, for example, a rod, to the user .
[0093] In addition, the use of the present foam in an aerosol generating apparatus as described above is revealed, preferably in a non-burning application, that is, in which the foam is not burned.
[0094] In addition, the present invention also provides a method of supplying a foam, particularly in accordance with the first and / or second and / or third aspects of the invention, to an aerosol generating apparatus as described above, wherein the method comprises: providing
Petition 870190060453, of 06/28/2019, p. 47/79
39/54 removable mode a foam to a receiving portion of the apparatus, the receiving portion being operatively connected to a heating system for the generation of an aerosol from said foam. In certain embodiments, the present foam is supplied to the receiving portion of the apparatus.
[0095] A kit for supplying a foam containing inhalable agent and / or agent containing tobacco ingredient is further disclosed, comprising a foam comprising a foam stabilizing agent, a foaming agent and optionally a first aerosol forming agent; and a mixture that contains
one agent inhalable and / or agent what contains ingredient in tobacco, and one second training agent aerosol,in . that the weight of inhalable agent and / or agent that
contains tobacco ingredient is 0.1 - 33% by weight of the foam and mixture weight, and the total weight of the first and second aerosol forming agents in the kit is 10 - 80% by weight, preferably 40 - 70% by weight, the weight of the foam and the mixture.
[0096] The present kit thus comprises at least two components, that is, the foam and the mixture. In addition, more than one mixture containing an agent containing tobacco ingredient and / or inhalable agent and a second (or third,
room etc. ) agent of formation aerosol can be contained by example, if a kit for provided, on what foams with many different flavors and / or aromas can be ready. If more than one mixture for provided, the agent
Petition 870190060453, of 06/28/2019, p. 48/79
40/54 containing tobacco ingredient and / or inhalable agent and the (second) aerosol forming agent can be the same or different. With the present kit, foams in line with the first aspect of the invention can also be prepared. Therefore, the foam stabilizing agent, the foaming agent, and an inhalable agent and / or the agent containing tobacco ingredient, as well as the amounts thereof, can be the same as discussed in relation to the foams of the first , second and third aspects of the present invention. In addition, the first and second aerosol forming agents and their amounts can be the same as discussed in relation to the foams of the first, second and third aspects of the present invention. The first and second aerosol forming agents can be the same or different. According to certain modalities, the inhalable agent and / or agent containing tobacco ingredient are adhered to an external foam surface in the kit when the mixture is applied to the foam, whereas the foam microstructure, for example, bubbles and / or pores, do not necessarily have to contain the inhalable agent and / or agent containing tobacco ingredient, although this is also not excluded. As in the first, second and third aspects, water and / or an acid and / or ester, for example diacetin, as well as other additional components, as given above, can be contained in the foam and / or in the kit mixture.
[0097] In the present kit, the foam and the mixture can each be supplied in a suitable packaging, which are not particularly restricted and may be the same as those discussed in relation to the foam of the first, second and
Petition 870190060453, of 06/28/2019, p. 49/79
41/54 third aspects of the invention, or may be different. For example, the mixture can also be supplied in a suitable applicator to be applied to the foam.
[0098] A foam (also called raw foam) which further comprises a foam stabilizing agent, a foaming agent and an aerosol forming agent, wherein the weight of the aerosol forming agent in the foam is 10-80% by weight, preferably 40 - 70% by weight, of the foam weight. This foam represents, according to certain embodiments, a foam as similarly described in relation to the present kit, as well as a foam of the first and / or second and / or third aspects without the inhalable agent and / or agent containing tobacco ingredient.
[0099] So again, the foam stabilizing agent and the foaming agent, as well as the aerosol forming agent and the amounts of each, can be adjusted as with respect to the first, second and third aspects of the invention. Such foam can serve as a raw foam in the present kit, that is, to add suitable flavors and / or aromas. In addition, water and / or an acid and / or ester, for example, diacetin, particularly water and / or ester, for example, diacetin, as well as other additional components, as given above, can be contained in that crude foam. According to certain embodiments, the raw foam essentially consists of the foam stabilizing agent, the foaming agent and the aerosolizing agent. According to certain modalities, the raw foam consists of the foam stabilizing agent, the foaming agent
Petition 870190060453, of 06/28/2019, p. 50/79
42/54 foam and aerosol forming agent.
[0100] The raw foam can be prepared through the same steps, as described in the present methods, except that the step of adding the inhalable agent and / or the agent containing tobacco ingredient is absent.
[0101] Therefore, a (third) foaming method is disclosed, which comprises mixing an aerosol forming agent, a foaming agent and optionally a solvent, which is not particularly limited and can comprise, for example , purified water, an acid and / or ester, for example, diacetin, and / or an alcohol such as ethanol, 1-propanol and / or 2-propanol, or mixtures thereof, under heating, optionally injecting or circulating in a gas, for example, during heating, where the gas can be, for example, air, oxygen, nitrogen, or mixtures thereof, add a foam stabilizing agent and cool the mixture.
[0102] Furthermore, a (fourth) foaming method is disclosed, which comprises mixing an aerosol forming agent and optionally a solvent, under heating; add a foaming agent; optionally inject a gas; add a foam stabilizing agent; and cool the mixture. The steps can therefore be carried out with the ingredients and quantities of the same and in the order discussed in relation to the first and second methods.
[0103] A package is also revealed, containing the foam of the first, second and / or third aspects and / or the raw foam discussed above. According to certain modalities, the foam of the first, second and / or third
Petition 870190060453, of 06/28/2019, p. 51/79
43/54 aspects and / or the raw foam is sealed in the packaging, particularly sealed in order to prevent the entry of water and / or water vapor. The sealing is not particularly restricted in this regard, and the packaging may, for example, be a blister-type package with an aluminum lining, or something similar, as, for example, known from pharmaceutical packaging. According to certain modalities, the packaging prevents water absorption at a temperature between -20 and +40 ° C and at a relative humidity between 20 and 80% of more than 1% by weight, based on the weight of the foam, within over a period of one year, based on the weight of the foam. According to a certain modality, a water absorption of more than 1% by weight, based on the weight of the foam, is prevented in at least 90% of the inhabited places on Earth, preferably in at least 90% of the places on Earth.
[0104] The above modalities can be combined arbitrarily, if appropriate. Other possible embodiments and implementations of the invention also comprise combinations of features mentioned not explicitly in the above or below in relation to the examples of the invention. In particular, one skilled in the art will also add individual aspects such as enhancements or additions to the respective basic form of the invention.
Examples [0105] The present invention will now be described in detail with reference to its examples. However, these examples are illustrative and do not limit the scope of the invention.

Example 1:
[0106] Table 1 shows components used to produce an exemplary embodiment of the present foam.
[0107] To produce the example foam, the ingredients given in the respective column of Table 1 were mixed and combined as follows.
[0108] First, propylene glycol and glycerin were mixed and stirred, followed by mixing in purified water and stirring again. Then, the gellan gum was added, and the mixture was stirred again. The entire mixture was then heated to about 70 ° C for 5 minutes to initiate bubble formation. After adding the
Petition 870190060453, of 06/28/2019, p. 53/79
45/54 tobacco powder for 5 minutes, the mixture was homogenized for another 10 minutes. Cekol® 2000 was added over 5 minutes as well, followed by mixing for another 10 minutes. Then, the mixture was cooled to 10 ° C in 10 minutes and aged at 50 ° C for 8 hours.
[0109] The foam obtained in this way was formed as a tube / rod with a tunnel formed inside and cut into smaller portions used in a test to determine its smoke profile.
[0110] Figure 1 shows the smoke profile obtained in this test, that is, of a steamed mousse that comprises the present foam. In Figure 1, the lower line indicates the total particulate matter (TPM) per puff in mg, shown on the left side of the figure, and the upper line shows the flavor intensity, in which the first puff is adjusted to a flavor intensity of 100%, indicated on the right side of the figure. The intensity of flavor and TPM can be maintained at almost the same level by a large number of puffs, before decreasing quite quickly. This indicates a very efficient extraction of volatile components when heated. PMS can be kept consistent for up to 30 puffs, which corresponds to constant delivery, followed by a marked decrease in PMS, as the product is substantially extracted from the foam. A significant factor behind consistent delivery may be the foam's open pore structure.
Example 2:
[0111] Example 2 was prepared as described in Example 1, using the appropriate amounts for the
Petition 870190060453, of 06/28/2019, p. 54/79
46/54 components, as given in Table 1 in the respective column.
Example 3:
[0112] Example 3 was prepared as described in
Example 1, using the appropriate amounts for the components, as given in Table 1 in the respective column.
Example 4:
[0113] Example 4 was prepared as described in
Example 2, except that tobacco powder was replaced with menthol.
Examples 5 to 9:
[0114] Examples 5 to 9 were prepared as described in Example 1, with the amount given in Table 2.

Examples 10 and 11:
[0115] Example 10 was performed like Example 5, except for the amount of water that was reduced to 0.5% by weight, in which the amount of aerosol forming agent was increased accordingly.
[0116] Example 11 was performed like Example 5, except for the amount of water that was increased to 5.0% by weight, in which the amount of aerosol forming agent was decreased accordingly.
Example 12:
[0117] Example 12 was performed like Example 5, except for tobacco powder which had particles <30 pm in size which was replaced by a mixture of two tobacco powders, one of which was tobacco powder which had particles with a size <30 pm (80% by weight, based on the total weight of the tobacco powder), and one of which was a particulate tobacco powder with a size of about 250 pm (20% by weight, based on in the total weight of the tobacco powder). After the formation of the foam, both were included in an e-cigarette with a suitable capsule to receive the foam (which was cut to a suitable size), and heated to about 200 ° C. The aerosol generated was inhaled by a jury of 5 subjects and compared to an aerosol that was obtained by heating the foam of Example 5 in the same way. Overall, the aerosol from Example 12 was found to be less rough.
Examples 13 and 14:
[0118] Examples 13 and 14 were performed like Example 8, except for tobacco powder which was replaced by menthol (Example 13) and Logic fruity e-liquid (Example 14),
Petition 870190060453, of 06/28/2019, p. 57/79
49/54 respectively.
Example 15:
[0119] Example 15 was performed like Example 5, except that no tobacco particle was added and the amount of foam components was adjusted accordingly.
Example 16 [0120] To test the performance of different foams of the invention, different batches were prepared with systematic changes of components in them, prepared in a cylinder with a central hole, and offered to a test panel of 7 people who were testing the their aroma and flavor by vaporization.
[0121] The composition of the different lots is given in table 3 below, with the weights given in relation to the total composition.
