[0037] As used in this disclosure, a range "XY" includes X and Y as endpoints.

[0038] 1. Aerosol generating sheet

[0039] An aerosol-generating sheet is, for example, a sheet capable of generating an aerosol by being heated. In one embodiment, the aerosol-generating sheet (sometimes referred to hereinafter as simply a "sheet") comprises (A) 15% to 50% by weight of a tobacco extract, (B) a non-wood fiber, (C) a binder, and (D) 10% to 60% by weight of an aerosol source, wherein the sum of (B) and (C) is 23% to 50% by weight based on the weight of the sheet. Unless otherwise indicated, weights and weight percentages are dry weights and dry weight percentages. Dry weight is weight excluding the weight of water.

[0040] (1) Ingredient (A): Tobacco extract

[0041] Tobacco extracts are flavor substances or mixtures extracted from tobacco. Tobacco extracts can be prepared by known methods. The following methods are examples: 1) a method of extracting tobacco raw material using a medium to obtain a tobacco extract; 2) a method of adding a medium to the tobacco raw material, heating the mixture, and collecting the resulting vapor; and 3) a method of allowing a hot vaporized medium to pass through the tobacco raw material and collecting the vapor that has passed through. The medium can be water or a hydrophilic organic solvent, such as an alcohol. For example, in method 1), water is preferably used as the medium for processability. In methods 2) and 3), alcohol (such as propylene glycol, glycerol, or ethanol) is preferably used as the medium for work efficiency. Acids or alkalis can also be used for extraction as needed. The liquid containing the tobacco extract and the medium obtained by extraction is called a tobacco extract.

[0042] Raw materials of the genus Nicotiana (such as common tobacco (Nicotiana tabacum) and yellow tobacco (Nicotiana rustica)) can be used as tobacco raw materials. Examples of common tobacco that can be used include varieties such as Burley tobacco (Burleytobacco) and yellow tobacco (yellow tobacco). Oriental tobacco (Oriental tobacco) or Burley tobacco, which are native species of the genus Nicotiana, can also be used.

[0043] The tobacco raw material can be chopped or powdered tobacco raw material (hereinafter also referred to as " raw material sheet "). In this case, the particle size of the raw material sheet is preferably 0.5 to 1.18 mm. This type of raw material sheet is for example obtained by screening according to JIS Z 8815 using the stainless steel sieve according to JIS Z 8801. For example, 1) use the stainless steel sieve with 1.18 mm openings to screen the raw material sheet in the time period of 20 minutes by drying and mechanical oscillation, to obtain the raw material sheet passing the stainless steel sieve with 1.18 mm openings. 2) then use the stainless steel sieve with 0.50 mm openings to screen the raw material sheet in the time period of 20 minutes by drying and mechanical oscillation, to remove the raw material sheet passing the stainless steel sieve with 0.50 mm openings. Therefore, the raw material sheet can be prepared by passing the stainless steel sieve with a specified upper limit (1.18 mm openings) and not passing the stainless steel sieve with a specified lower limit (0.50 mm openings).

[0044] On the one hand, with alkali treatment tobacco raw material.Can collect the tobacco extract liquid that comprises tobacco extract and water to prepare the flavor component produced by said processing.At this moment, flavor component preferably extracts from the tobacco raw material of alkali treatment with gaseous form, and preferably gas is introduced into water so that flavor component is transferred to liquid thus.

[0045] The alkaline substance is preferably an alkaline liquid, such as potassium carbonate aqueous solution. At this point, the alkaline substance is supplied until the pH of the tobacco raw material is within a certain range. The pH is preferably at least 8.0 and more preferably 8.9 to 9.7. The pH of the tobacco raw material is the pH of water when the tobacco raw material is mixed with 10 times the amount of water.

[0046] The moisture content of tobacco raw material is not restricted, but is preferably about 5% to 30% by weight for the consideration of effective flavor component extraction.The moisture content of tobacco raw material can be determined by known methods; For example, moisture content can be defined as the weight loss that occurs at the time point where 1 g sample has been heated to 105 ° C and heated until the weight change rate is not more than 1 mg / min. This can for example be determined using a moisture analyzer (such as MB45, OHAUS CORPORATION) with a halogen heat source.

[0047] The sheet has a tobacco extract content of 15% to 50% by weight. Where appropriate, this amount can be adjusted to, for example, between 20% and 40% by weight.

[0048] (2) Component (B): Non-wood fiber

[0049] Non-wood fibers are fibers not derived from wood, and are preferably fibers other than tobacco fibers. Tobacco fibers are less likely to make the sheet stronger and may cause an astringent taste. Dietary fibers are preferred as non-wood fibers. Dietary fibers are dietary components that are indigestible by human digestive enzymes, and are more preferably water-insoluble dietary fibers. Dietary fibers can be porous, specifically, sponge-like. Porous fibers can increase the surface area of ​​the smoking article sheet and improve the thermal conductivity of the sheet. For example, the fiber is preferably citrus fiber because it is readily available. Citrus fiber is primarily composed of the mesocarp of citrus fruits. Dietary fiber can also be short fibers or columnar particles with a small aspect ratio. Citrus fiber is particularly preferred because it can be used in small quantities to make the sheet stronger. The moisture content of the non-wood fibers is determined in order to determine how much non-wood fiber should be blended to meet the above relationship. The moisture content of the non-wood fibers can be determined by known methods, and can be determined, for example, in the same manner as the moisture content of tobacco raw materials. In one aspect, the content of component (B) in the sheet is 10% to 30% by weight. Wood fiber is a known fiber material, but the advantage of using non-wood fiber is that the liquid carrying capacity is better than that of wood fiber. Therefore, the amount of non-wood fiber added can be reduced to increase the amount of ingredients that contribute to the flavor and aroma of smoking.

[0050] (3) Component (C): Adhesive

[0051] Examples of the binder include carboxyalkyl cellulose and guar gum.The moisture content of the binder can be determined by a known method, and can be determined, for example, in the same manner as the moisture content of the tobacco raw material.

[0052] The total amount of component (B) and component (C) in the sheet is 23% to 50% by weight. Amounts below this lower limit will result in poor sheet handling and insufficient sheet strength. Amounts above this upper limit will result in a less flavorful or a more astringent taste. Processing of the sheet (such as cutting or folding) will also become more difficult. In this regard, the lower limit of the total amount is preferably 24% by weight or more, and the upper limit is preferably 40% by weight or less, and more preferably 30% by weight or less. The amounts of component (B) and component (C) are determined to meet the above total amount, but in one aspect, the amount of component (B) is 10% to 30% by weight or 13% to 25% by weight, and the amount of component (C) is 13% to 20% by weight or 10% to 25% by weight.

[0053] (4) Component (D): Aerosol source

[0054] The example of aerosol source comprises polyol, such as glycerol or polyethylene glycol.The water content of aerosol source can be determined by known methods, and can for example determine in the mode identical with the water content of tobacco raw material.The amount of aerosol source in the sheet material is 10% to 60% by weight.The amount below this lower limit will cause the smoke quantity not enough in the smoking process.The amount above this upper limit will cause the sheet material to handle badly.In this respect, this amount is preferably 15% to 50% by weight and more preferably 20% to 40% by weight.

[0055] (5) Other ingredients

[0056] The sheet material can contain wood fiber. The example of wood fiber comprises softwood pulp, Vitacel FL400 and Vitacel L600 / 30 (all from J. Rettenmaier & Sohne company). As described below, the mixture for producing the sheet material preferably comprises water, wherein the water in the mixture: the non-aqueous component weight ratio is preferably (2 to 10): 1. It is preferred to determine the moisture content of the wood fiber so that how much wood fiber should be blended to satisfy the above relationship. The moisture content of the wood fiber can be determined by known methods, and can for example be determined in the same manner as the moisture content of tobacco raw material. On the one hand, the content of wood fiber is 1% to 10% by weight in the sheet material.

[0057] The sheet may also contain known flavoring agents. Examples of flavoring agents include, but are not limited to, menthol, and any of the following may be used. The amount of flavoring agent may also be a known amount. These examples of flavoring agents may be used alone or in combinations of two or more.

[0059] 2. Components of smoking products

[0060] Sheet material can be used as a component of a smoking article. Examples of smoking article components that include sheet material include flavor sources, wrappers, paper tubes, filters, and containers. For example, the sheet material can be folded or spiral-shaped, or cut into strands or fragments for use as a flavor source in smoking articles, specifically, as filler for tobacco rods. The strands have a rectangular shape and can be arranged longitudinally along the flavor source or randomly arranged. Fragments are also randomly arranged within the flavor source.

[0061] 3. Smoking products

[0062] The smoking article component can be used in smoking articles. For example, a burn-not-burn smoking article or a heat-not-burn smoking article can be prepared that includes the above tobacco rod and the mouthpiece component. The mouthpiece can include a filter and a cooling portion to promote aerosolization of the vapor generated from the flavor source. The cooling portion can be composed of a paper tube. The paper tube can be filled with a material (such as a polylactic acid sheet) to promote cooling and can provide multiple longitudinally connected flow paths. In addition, the circumferential surface of the cooling portion can be provided with openings through which external air is drawn in. The filter can be composed of an acetate filter, a paper filter, a center hole filter, or a combination thereof.

[0063] For example, an acetate filter, a paper filter or a center hole filter may be provided as a tip plug upstream of the tobacco rod, where upstream is the direction opposite to the mouthpiece end.

[0064] 4. Production Method

[0065] The sheet of this embodiment is preferably produced by the following method, which includes: step 1, wherein a mixture containing a tobacco extract liquid containing component (A) (tobacco extract), component (B) (non-wood fiber), component (C) (binder) and component (D) (aerosol source) is prepared; and step 2, wherein the mixture is formed into a sheet.

[0066] (1) Step 1

[0067] (1-1) Preparation of tobacco extract

[0068] In this step, extract above-mentioned tobacco raw material to prepare the tobacco extract liquid that comprises tobacco extract active ingredient and medium.Preferably use water as medium.For the consideration of smoking flavor, extraction temperature is not restricted, but is preferably 60 ℃ to 100 ℃, and is more preferably 70 ℃ to 90 ℃.Extraction time is preferably 20 to 40 minutes.

[0069] (1-2) Mixed

[0070] The ingredients can be mixed by known methods; for example, the mixture can be prepared by mixing the ingredients in a mixer. The mixture preferably contains water, with the water:non-aqueous component weight ratio preferably being (2 to 10):1. The water can be the water contained in the tobacco extract or can be additional water that has been added. In particular, as the non-wood fiber content increases, the water content is preferably also increased. Preferred embodiments are described below.

[0071] [When manufacturing a laminated sheet]

[0072] The following three methods can be cited.

[0073] 1) A tobacco extract is mixed with a binder to prepare mixture X. If water is to be added, additional water is also mixed to prepare mixture X. An aerosol source, such as glycerin, is mixed with other solids to prepare mixture Y. Mixture X is then mixed with mixture Y. Specifically, the other solids are component (B) or other components described above.

[0074] 2) Mix the tobacco extract with an aerosol source, such as glycerin. Add the binder to this mixture and mix with it. If water is to be added, mix it in at this time. Then mix the other solids with this mixture.

[0075] 3) Mix an aerosol source, such as glycerin, with a binder. Mix the tobacco extract with this mixture. If water is to be added, mix it in now. Then mix any other solids with this mixture.

[0076] The above method involves mixing the binder with the tobacco extract (and water, if desired). This mixing prevents the solid from preferentially absorbing water and allows the binder to dissolve in the water without "clumping," thereby fully realizing the binder's function. The method of first mixing the binder with the aerosol source makes the binder particularly unlikely to "clump." "Clumping" refers to a state in which the ingredients exist in a clumped form, rather than being dispersed or dissolved.

[0077] [Casting sheet]

[0078] The tobacco extract is mixed with an aerosol source, such as glycerin. If water is to be added, it is also mixed in at this point. A binder is mixed with the mixture, and after confirming that the binder has been mixed until uniform, other solids are mixed in. When the solids containing the binder are first mixed with one another, the binder will "clump," a difficult-to-solve condition. In this method, the binder is first mixed with the aerosol source, thereby reducing the likelihood of the binder "caking."

[0079] (2) Step 2

[0080] The sheet can be made by known methods. For example, the sheet can be made using a casting method or a rolling method. In the casting method, the mixture is cast onto a substrate to form a wet sheet. The wet sheet is then dried to obtain a sheet. The drying temperature is preferably 50°C to 100°C. Sheets obtained by this method are also referred to as "cast sheets."

[0081] In the rolling method, the mixture (when sandwiched between two substrate films) is rolled to a predetermined thickness (greater than 100 μm) by a pair of rollers using a calendering device (e.g., from Yuri Roll Machine Co., Ltd.), thereby producing a laminate comprising a wet sheet between the two substrate films. The laminate may be rolled multiple times. The substrate films are preferably non-sticky films such as fluoropolymer films, a specific example of which is Teflon® film.

[0082] One of the substrate films of the laminate is then peeled off. The laminate is dried using a forced air dryer. The drying temperature is preferably between 50°C and 100°C, and the drying time can be 1 to 2 minutes. The remaining substrate film is then peeled off and further dried under the same conditions to obtain a sheet. Drying in this manner prevents the sheet from adhering to another substrate.

[0083] The sheets obtained by this method are also called "laminated sheets". Laminated sheets are preferred because they have a smooth surface and can prevent the cut tobacco from spilling when it comes into contact with other components. This method is also suitable for producing sheets of 300 μm or less.

[0084] In the rolling method, the amount of water in the mixture obtained in step 1 is preferably adjusted to between 20% and 80% by weight, and more preferably between 20% and 40% by weight, and a moist powder (powder in a moist state) is preferably produced. The moist powder is then preferably kneaded using a single-screw or multi-screw kneader such as a kneader (e.g., Dalton's DG-1) and then prepared into a laminate.

[0085] Examples

[0086] Example 1

[0087] Ground yellow tobacco and oriental tobacco were prepared as tobacco raw materials. The chopped tobacco leaves were extracted with 500% by weight of water relative to the dry weight of the tobacco leaves at room temperature to obtain a tobacco extract.

[0088] A mixture was prepared using Herbacel AQ Plus CF-D / 100 (DSP Gokyo Food & Chemical Co., Ltd.) as the non-wood fiber, carboxyalkyl cellulose (CMCF30MC, Nippon Paper Industries Co., Ltd.) as the binder, and glycerin as the aerosol source in the proportions shown in Table 1. The ratio of the total amount of water in the mixture to the total amount of non-aqueous components was 1:4. The total amount of water here refers to the total weight of the water contained in each component. The weight of water in each component was determined by the above-described method.

[0089] The resulting mixture was cast onto a stainless steel sheet and dried in an oven at 80°C to produce a 0.25 mm thick cast sheet. The dried sheet was then further conditioned at 22°C and 60% RH for at least overnight. At this point, the sheet was evaluated for its ability to hold the liquid, its stickiness, and its oozing of liquid onto the surface of the sheet. The results are shown in Table 1. The weights shown in the table are dry weights in each case.

[0090] Evaluation Criteria

[0091] a: Minimal sheet stickiness, no liquid seepage

[0092] b: No liquid seepage, but the sheet is obviously sticky

[0093] c: Liquid exudation

[0094] Examples 2 to 6

[0095] Cast sheets were prepared and evaluated in the same manner as in Example 1, except that the formulation of the ingredients was changed as shown in Table 1.

[0096] Comparative Examples 1 to 7

[0097] Cast sheets were prepared and evaluated in the same manner as in Example 1, except that the formulation of the ingredients was changed as shown in Table 1.
