Disclosure of Invention

Problems to be solved by the invention

In the non-combustion heating type flavor-absorbing article, if the flavor-absorbing property can be easily adjusted, various tastes of users can be dealt with. In conventional combustion-type tobacco, the flavor is diluted by introducing air from perforations provided in the filter or the mouthpiece side. However, in a non-combustion heated type flavor-drawn article in which an aerosol is generated by heating a tobacco-containing segment to a relatively low temperature, if air is introduced from a perforated hole provided on the filter or the mouthpiece side, the aerosol is reagglomerated, and thus there is a problem that sufficient release cannot be achieved. In addition, the method described in the above patent document can also adjust the odor and taste, but there is still room for improvement. Therefore, in order to adjust the flavor of the non-combustion heating type flavor-suctioned article, a new solution is required. In view of the above, an object of the present invention is to provide a non-combustion heating type flavor-absorbing article exhibiting a diluted flavor.

(1) Paper sheet

(1-1) first mode

As a first embodiment, the tobacco segment for heating contains a tobacco material and paper having a total content of lignin and hemicellulose of 0.1 to 10 wt% as a filler. The filler is used for tobacco segments. Lignin refers to a high molecular phenol compound contained in trees and the like. Hemicellulose refers to insoluble polysaccharides contained in the cell wall. If the total amount is within this range, the unpleasant smell (such as fibrous smell) during smoking can be reduced. That is, in this embodiment, the effect of diluting the flavor and taste without seriously impeding the original flavor and taste is achieved. From this viewpoint, the upper limit of the total content of lignin and hemicellulose is preferably 9.0 wt% or less.

Lignin and hemicellulose are measured by a known method, but in the present invention, they are preferably measured by the following method.

[ quantification of hemicellulose ]

1) The paper was subjected to solvent extraction using water as a solvent, and the residue was separated. The residue was freeze-pulverized using liquid nitrogen or the like to obtain sample a.

2) Sample a was reacted with an enzyme, and the reaction product was recovered.

3) The reaction product was hydrolyzed, absorbance of the hydrolyzed product was measured at 490nm, and hemicellulose was quantified.

Step 1) can be performed using Thermo Scientific, for example ^TM Dionex ^TM ASE ^TM High-speed solvent extraction system (model: ASE-350).

Step 2) can be specifically performed as follows.

50mg of sample A was placed in a screw flask, 8.5ML of ultrapure water (ML-Q water) and 0.5ML of pancreatin solution were added thereto, and the mixture was shaken at 125rpm at 40℃for 16 hours. The pancreatin solution was obtained by adding 8g of pancreatin to 100ml of 0.1M phosphate buffer solution at pH6.4, stirring for 1 hour, and then subjecting the mixture to centrifugation at 8000rpm for 30 minutes. Next, the sample liquid was transferred to a 15ML centrifuge tube using ML-Q water, and centrifuged at 8000rpm for 15 minutes to remove the sample liquid. This washing was repeated three times. After washing, 10ml of a 5% aqueous sulfuric acid solution was added, and hydrolysis was performed at 100℃for 2.5 hours. After the hydrolysis reaction, the sample was naturally cooled to room temperature. Next, the precipitate was filtered and the filtrate was recovered into a 250ml pear-shaped flask. After the residue on the filter paper was sufficiently washed with ML-Q water, the volume was set at 250ML. The solution was used as a sample for hemicellulose measurement. The sample was transferred in 500. Mu.l to a 20ml test tube, and 500. Mu.l of 5% phenol aqueous solution and 2.5ml of concentrated sulfuric acid were added thereto and stirred vigorously for ten seconds. The sample was allowed to stand at room temperature for 20 minutes or longer, and absorbance was measured at a wavelength of 490nm using a spectrophotometer to quantify hemicellulose.

[ quantification of lignin ]

i) The sample a was prepared.

ii) refluxing the sample A in an aqueous acid solution, and filtering and separating the sample after the refluxing treatment.

Iii) the sample separated by filtration was dried and weighed as lignin amount.

The steps ii) and iii) can be specifically performed as follows.

100mg of sample A was placed in a screw flask, and 4ml of 72% sulfuric acid was added thereto, and the sample was completely immersed in sulfuric acid, and the mixture was shaken at 200rpm at 30℃for 4 hours. Then, 157.2ML of ultrapure water (ML-Q water) was added so that the concentration of the diluted sulfuric acid became 4%, transferred to a pear-shaped flask, and heated and refluxed in an oil bath at 110℃for 2 hours. Naturally cooling to room temperature, filtering, drying by a rotary dryer, and weighing.

The density of the paper used in this embodiment is preferably 0.05 to 0.8 (g/cm ³ ) More preferably 0.1 to 0.6 (g/cm) ³ ). The density is measured by a known method, preferably by the following formula.

Density (g/cm) ³ ) =weight (g)/area (cm) ² ) Thickness (cm)

The content of the paper used in the present embodiment is preferably 5 to 70% by weight, more preferably 10 to 50% by weight, and even more preferably 15 to 40% by weight, based on the dry weight of the tobacco sheet. If the paper content is within this range, the odor can be diluted to an appropriate level without affecting the original odor. In one aspect, the dry weight refers to the weight of the residue when the tobacco material is dried at 100 ℃ for 5 hours.

The paper used in the present embodiment is not limited as long as the total content of lignin and hemicellulose is within the above range, and for example, paper for tobacco such as wrapping paper, paper for printing such as high-quality printing paper and medium printing paper can be used. However, from the viewpoint of suppressing the generation of odor, non-coated paper or micro-coated paper is preferable. The paper used in the present embodiment may or may not contain an aerosol-generating substrate described below. The amount may be in the range described in the second embodiment or may be other than the range.

(1-2) second mode

As a second aspect, the tobacco segment for heating contains a tobacco material and paper containing an aerosol-generating substrate as a filler. The aerosol-generating substrate is a material that generates an aerosol by heating and cooling, or generates an aerosol by atomizing. In this embodiment, since the paper including the aerosol-generating substrate is used, the effect of diluting the flavor and taste without reducing the smoke amount is achieved. As the aerosol-generating substrate, a known aerosol-generating substrate can be used. Examples thereof include polyols such as glycerin, vegetable glycerin, propylene Glycol (PG), and the like, triethyl citrate (TEC), triacetin, and the like. The amount of the aerosol-generating substrate is preferably 3 to 20% by weight, more preferably 5 to 15% by weight, based on the dry weight of the paper. If the amount of the aerosol-generating substrate exceeds the upper limit, dirt or the like may be generated in the tobacco segment, and if the amount is less than the lower limit, the smoke feeling may be reduced. The aerosol-generating substrate can be added to the paper by impregnation, spraying, or the like.

The content of the paper to which the aerosol-generating substrate is added is preferably 5 to 75% by weight, more preferably 10 to 50% by weight, and even more preferably 15 to 40% by weight, based on the dry weight of the tobacco material.

The paper used in the present embodiment is not limited, and may be the paper described in the first embodiment. The density of the paper before the aerosol-generating substrate is added used in the present embodiment may be within the range described in the first embodiment or may be within a range other than the range. The amount of lignin and hemicellulose contained in the paper used in the present embodiment is not limited, and may be in the range described in the first embodiment or may be other than the range.

(1-3) shape, etc

In any of the modes, the shape of the paper is not limited, as long as the paper is a shape that is easily mixed with the tobacco material. In one aspect, the paper is a sheet, wire, or strand. In addition, in a preferred form, the paper and tobacco material are the same shape, and in a most preferred form, both the paper and tobacco material are filaments.

In addition, a perfume or the like generally used in the art, such as menthol, may be added to the paper.

(2) Tobacco material

The tobacco material is a material derived from plants of the genus nicotiana. Specific examples of the tobacco material include cut tobacco, tobacco fine powder, tobacco stems, tobacco flakes, strands, and the like which are generally used in this field. They may be used alone or in combination. Among them, cut tobacco and cut tobacco pieces are preferable from the viewpoints of excellent mixing with paper, no improvement in ventilation resistance, easiness in contributing to flavor absorption, high uniformity in shape, and the like.

Tobacco leaves belonging to the genus Nicotiana, such as Nicotiana, nicotiana tabacum, and Nicotiana tabacum, can be suitably used. Although not limited to variety, one or more kinds of these tobaccos may be used in combination. As the mixture, a mixture in which the above-mentioned respective varieties are appropriately blended to the target taste can be used.

(3) Method of manufacture

The tobacco segments can be manufactured by any method, for example, by mixing the tobacco material described above with the paper described above and wrapping it around a paper. As the wrapping paper, wrapping paper commonly used in the art can be used.

2. Non-combustion heated flavor smoking article

In the present invention, the "fragrance-suctioning article" means an article that a user uses to suction fragrance. Among the flavor-absorbing articles, tobacco or a material having a component derived from tobacco is referred to as "tobacco flavor-absorbing article". Tobacco flavor smoking articles are broadly classified into "combustion type tobacco flavor smoking articles" (also simply referred to as "smoking articles") that produce a flavor by combustion, and "non-combustion type tobacco flavor smoking articles" that do not produce a flavor by combustion. Further, the non-combustion type tobacco flavor-absorbing article is largely classified into a "non-combustion heating type tobacco flavor-absorbing article" which generates a flavor by heating, and a "non-combustion non-heating type tobacco flavor-absorbing article" which generates a flavor by not heating. The paper-containing tobacco segments of the present invention are suitable for non-combustion heated tobacco flavor smoking articles.

Fig. 2 shows one embodiment of a non-combustion heating type tobacco flavor smoking article. As shown in the figure, the non-combustion heating type tobacco flavor smoking article 20 includes a tobacco segment 20A, a tubular cooling portion 20B having a hole formed in the circumference thereof, and a filter portion 20C. The non-combustion heating type tobacco flavor smoking article 20 may have other components. The axial length of the non-combustion heating type tobacco flavor smoking article 20 is not limited, but is preferably 40 to 90mm, more preferably 50 to 75mm, and even more preferably 50 to 60mm or less. The circumferential length of the non-combustion heating type tobacco flavor smoking article 20 is preferably 16 to 25mm, more preferably 20 to 24mm, and even more preferably 21 to 23mm. For example, the length of the tobacco segment 20A is 20mm, the length of the cooling portion 20B is 20mm, and the length of the filter portion 20C is 7mm. The length of each of these components can be appropriately changed according to manufacturing suitability, required quality, and the like. Although fig. 2 shows the first stage 25 being disposed, the second stage 26 may be disposed only on the downstream side of the cooling unit 20B without disposing the first stage 25.

1) Tobacco segment 20A

The tobacco filler 21 in the tobacco segment 20A comprises the tobacco material and paper described above. The method of filling the tobacco filler 21 into the wrapping paper 22 is not particularly limited, and for example, the tobacco filler 21 may be wrapped with the wrapping paper 22, or the tobacco filler 21 may be filled into the cylindrical wrapping paper 22. When the shape of the tobacco and paper has a long direction like a rectangle, the tobacco and paper may be filled so that the long direction becomes an unspecified direction in the wrapping paper 22, or may be aligned in the axial direction of the tobacco segment 20A or aligned in a direction orthogonal thereto. In addition, the above paper may be used as the wrapping paper 22. By heating the tobacco segment 20A, the tobacco component, aerosol-generating substrate, and water contained in the tobacco filler 21 are gasified for smoking.

2) Cooling unit 20B

The cooling unit 20B is preferably formed of a cylindrical member. The tubular member may be, for example, a paper tube 23 formed by processing thick paper into a cylindrical shape. In addition, in order to form the channels, the cooling portion 20B may be formed by a sheet of a thin material obtained by crimping, then pleating, or folding. As such a material, for example, a sheet material selected from polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polylactic acid, cellulose acetate, and aluminum foil can be used. The total surface area of the cooling portion 20B is appropriately adjusted in consideration of the cooling efficiency, and may be, for example, 300 to 1000mm ² /mm. Perforations 24 are preferably provided in the cooling portion 20B. By the presence of the through holes 24, the outside air is introduced into the cooling portion 20B at the time of suction. As a result, the aerosol-gasifying component produced by heating the tobacco segment 21A is brought into contact with the outside air, and the temperature thereof is lowered, so that the aerosol is formed by liquefaction. The diameter (diameter length) of the through hole 24 is not particularly limited, and may be, for example, 0.5 to 1.5mm. The number of the perforations 24 is not particularly limited, and may be one or two or more. For example, a plurality of perforations 24 may be provided on the circumference of the cooling portion 20B.

The cooling portion 20B can be formed in a rod shape having a length in the axial direction of, for example, 7 to 28 mm. For example, the length of the cooling portion 20B in the axial direction may be 18mm. The cooling portion 20B may have a substantially circular cross-sectional shape in the axial direction, and may have a diameter of 5 to 10mm. For example, the diameter of the cooling portion can be set to about 7mm.

3) Filter unit 20C

The structure of the filter portion 20C is not particularly limited, and may be composed of a single filler layer or a plurality of filler layers. The outside of the filling layer may be wrapped by one or more rolls. The ventilation resistance of the filter portion 20C can be appropriately changed according to the amount of filler, the material, and the like that are filled in the filter portion 20C. For example, in the case where the filler is cellulose acetate fiber, if the amount of cellulose acetate fiber filled in the filter portion 20C is increased, the ventilation resistance can be increased. At the position ofIn the case where the filler is cellulose acetate fiber, the packing density of the cellulose acetate fiber may be 0.13 to 0.18g/cm ³ . The air flow resistance was measured by an air flow resistance measuring instrument (trade name: manufactured by SODIMAX, SODIM).

The circumferential length of the filter portion 20C is not particularly limited, but is preferably 16 to 25mm, more preferably 20 to 24mm, and still more preferably 21 to 23mm. The length of the filter portion 20C in the axial direction (horizontal direction in FIG. 2) can be selected from 4 to 10mm so that the ventilation resistance thereof is 15 to 60mmH ₂ The manner of O/seg. The axial length of the filter portion 20C is preferably 5 to 9mm, more preferably 6 to 8mm. The cross-sectional shape of the filter portion 20C is not particularly limited, but may be, for example, circular, elliptical, polygonal, or the like. Further, a destructive capsule containing a perfume, a perfume bead, or a perfume may be directly added to the filter portion 20C.

The filter portion 20C may include a center hole portion as the first segment 25. The center hole portion is constituted by a first filler layer 25a having one or more hollow portions, and an inner plug wrap (inner roll paper) 25b covering the filler layer. The center hole portion has a function of improving the strength of the mouthpiece portion. The center hole portion may be formed by thermoforming without the inner plug wrap 25 b. The filter portion 20C may also be provided with a second segment 26. The second segment 26 is composed of a second filler layer 26a and an inner plug wrap (inner roll paper) 26b covering the filler layer. The second filler layer 26a may be a rod having an inner diameter of 5.0 to 1.0mm, which is filled with, for example, cellulose acetate fibers at a high density, and to which a plasticizer containing triacetin is added in an amount of 6 to 20% by weight relative to the weight of cellulose acetate, and which is cured. Since the second filler layer has a high packing density of fibers, air and aerosol flow only in the hollow portion during suction, and hardly flow in the second filler layer. Since the second filling layer inside the center hole portion is a fiber filling layer, the feeling from the outside is less likely to cause discomfort to the user when in use.

The first filler layer 25a and the second filler layer 26a are connected by a plug wrap (outer roll paper) 27. The outer plug wrap 27 may be, for example, cylindrical paper. In addition, the tobacco segment 20A, the cooling portion 20B, and the connected first and second filler layers 25a, 26a are connected by a tipping paper 28. These connections can be made by, for example, applying a slurry such as vinyl acetate on the inner surface of the tipping paper 28 and winding up the 3 members. These components may also be connected in multiple portions by multiple interleaving papers.

In particular, the combination of a non-combustion heated tobacco flavor smoking article and a heating device for generating an aerosol is also referred to as a non-combustion heated tobacco flavor smoking system. An example of this system is shown in fig. 2. In the figure, the non-combustion heating type tobacco flavor smoking system includes a non-combustion heating type tobacco flavor smoking article 20 and a heating device 10 for heating a tobacco segment 20A from the outside.

The heating apparatus 10 includes a body 11, a heater 12, a metal pipe 13, a battery unit 14, and a control unit 15. The body 11 has a cylindrical recess 16, and a heater 12 and a metal tube 13 are disposed at positions corresponding to tobacco segments 20A inserted therein. The heater 13 may be a heater using electric resistance, and the heater 12 may be heated by supplying electric power through the battery unit 14 in response to an instruction from the control unit 15 that performs temperature control. The heat emitted by the heater 12 is transferred to the tobacco segment 20A through the metal tube 13, which has a high thermal conductivity. The heating device 10 is shown in this figure as heating the tobacco segment 20A from the outside, but it may also be heated from the inside. The heating temperature by the heating device 10 is not particularly limited, but is preferably 400 ℃ or lower, more preferably 150 to 400 ℃, and still more preferably 200 to 350 ℃. The heating temperature represents the temperature of the heater of the heating apparatus 10.
