[Technical field]

[0001] The present invention relates to tobacco segments that include paper as a filler. [Background technology]

[0002] A non-combustion heat-type flavor inhalation article includes a tobacco segment filled with tobacco material, which generates a smoking flavor by being heated. To date, proposed articles include a non-combustion heat-type flavor inhalation article filled with tobacco material including a first sheet containing tobacco material and a second sheet containing a non-tobacco flavoring (Patent Document 1), a non-combustion heat-type flavor inhalation article filled with tobacco material including crimped paper (Patent Document 2), and a smoking article including a cellulose filler (Patent Document 3).

[0004] In a non-combustion heating type flavor inhalation article, if the flavor can be easily adjusted, it can meet various tastes of users. In conventional combustion type cigarettes, the flavor has been diluted by introducing air through a perforation provided on the filter or mouth side. However, in a non-combustion heating type flavor inhalation article that generates an aerosol by heating a tobacco-containing segment to a relatively low temperature, there is a problem that the aerosol re-aggregates when air is introduced through a perforation provided on the filter or mouth side, and sufficient delivery cannot be achieved. In addition, although the flavor can be adjusted by the method described in the above patent document, there is still room for improvement. Therefore, a new means is needed to adjust the flavor in a non-combustion heating type flavor inhalation article. In view of such circumstances, the present invention aims to provide a non-combustion heating type flavor inhalation article that exhibits a diluted flavor. [Means for solving the problem]

[0008] The present invention will be described in detail below. In the present invention, "X to Y" includes the extreme values ​​X and Y.

[0009] 1. Tobacco heating segment A tobacco segment is a substantially cylindrical member for releasing flavor components contained in tobacco material. A tobacco segment for heating is a tobacco segment that is heated to release flavor components. An overview of a tobacco segment is shown in FIG. 1A. A tobacco segment 20A includes a tobacco filler 21 and a wrapper 22 that wraps around the tobacco filler 21. The tobacco filler 21 includes tobacco material T and paper P. In this figure, the tobacco material T and paper P are in the form of a strand. The strand may be cut from a sheet in which sheet-shaped tobacco material T and paper P are laminated.

[0010] 1B shows an embodiment in which a sheet-like tobacco filler 21 is spirally filled into a wrapper 22. The sheet-like tobacco filler 21 may be a sheet obtained by laminating sheet-like tobacco material T and paper P, or may be a sheet obtained by joining sides of the sheet-like tobacco material T and paper P together or portions near the sides.

[0011] 1C shows an embodiment in which a sheet-like tobacco filler 21 is folded and filled into a wrapper 22. The sheet-like tobacco filler 21 may be a sheet obtained by laminating sheet-like tobacco material T and paper P, or may be a sheet obtained by joining sides of the sheet-like tobacco material T and paper P together or portions near the sides.

[0012] 1D shows an embodiment in which shredded tobacco filler 21 is filled into wrapper 22. In this figure, a shredded tobacco material T and shredded paper P are separately prepared and then filled. However, the shredded tobacco material may be obtained by cutting a sheet in which sheet-shaped tobacco material T and paper P are laminated together.

[0013] 1E shows an embodiment in which sheet-like tobacco filler 21 is compressed lengthwise and widthwise to be rolled and then filled into wrapper 22. Sheet-like tobacco filler 21 may be a sheet obtained by laminating sheet-like tobacco material T and paper P, or may be a sheet obtained by joining sides of sheet-like tobacco material T and paper P together or portions near the sides.

[0014] (1) Paper (1-1) First aspect In a first embodiment, the tobacco segment for heating contains, as a filler, a tobacco material and paper having a total content of lignin and hemicellulose of 0.1 to 10% by weight. The filler is a filler for the tobacco segment. Lignin is a high molecular phenolic compound contained in wood and the like. Hemicellulose is an insoluble polysaccharide contained in cell walls. When the total amount is within this range, it is possible to reduce unpleasant odors (such as fiber odors) during smoking. In other words, in this embodiment, an effect is achieved in which the smoking flavor can be diluted without significantly inhibiting the original smoking flavor. From this viewpoint, it is preferable that the upper limit of the total content of lignin and hemicellulose is 9.0% by weight or less.

[0015] Lignin and hemicellulose are measured by known methods, but in the present invention, they are preferably measured by the following method. [Quantitative determination of hemicellulose] 1) The paper is subjected to solvent extraction using water as a solvent, and the residue is separated. The residue is frozen and crushed using liquid nitrogen or the like to obtain sample A. 2) Sample A is reacted with an enzyme and the reaction product is collected. 3) The reaction product is hydrolyzed, and the absorbance of the hydrolyzate is measured at a wavelength of 490 nm to quantify the hemicellulose.

[0016] Step 1) can be carried out, for example, by using a method such as that described in Thermo Scientific TM Dionex TM ASE TM An accelerated solvent extraction system (model number: ASE-350) can be used.

[0017] Specifically, step 2) can be carried out as follows. 50 mg of sample A is placed in a screw bottle, 8.5 ml of ultrapure water (ML-Q water) and 0.5 ml of pancreatin solution are added, and the mixture is shaken at 40°C and 125 rpm for 16 hours. The pancreatin solution is the supernatant obtained by adding 8 g of pancreatin to 100 ml of 0.1 M phosphate buffer at pH 6.4, stirring for 1 hour, and then centrifuging at 8000 rpm for 30 minutes. The sample liquid is then transferred to a 15 ml centrifuge tube using ML-Q water, centrifuged at 8000 rpm for 15 minutes, and the supernatant is removed. This washing is repeated three times. After washing, 10 ml of 5% sulfuric acid aqueous solution is added, and hydrolysis is performed at 100°C for 2.5 hours. After the hydrolysis reaction is completed, the sample is allowed to cool to room temperature. The precipitate is then filtered off, and the filtrate is collected in a 250 ml measuring flask. The residue on the filter paper is thoroughly washed with ML-Q water, and the volume is adjusted to 250 ml. This solution is used as the sample for hemicellulose measurement. Transfer 500 μl of the sample to a 20 ml test tube, add 500 μl of 5% phenol solution and 2.5 ml of concentrated sulfuric acid, and stir vigorously for 10 seconds. Leave the sample at room temperature for 20 minutes or more, and then measure the absorbance at a wavelength of 490 nm using a spectrophotometer to quantify the hemicellulose.

[0018] [Quantitative determination of lignin] i) The sample A is prepared. ii) Sample A is refluxed in an aqueous acid solution, and the sample after refluxing is filtered. iii) The filtered sample is dried and then weighed to determine the amount of lignin.

[0019] Specifically, steps ii) and iii) can be carried out as follows. 100 mg of sample A is placed in a screw bottle, 4 ml of 72% sulfuric acid is added, the sample is completely immersed in the sulfuric acid, and shaken at 30°C and 200 rpm for 4 hours. Next, 157.2 ml of ultrapure water (ML-Q water) is added so that the sulfuric acid concentration after dilution is 4%, and the sample is transferred to an eggplant flask and heated to reflux in an oil bath at 110°C for 2 hours. After cooling to room temperature, the sample is filtered, dried in a rotary dryer, and weighed.

[0020] 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, but is preferably calculated by the following formula: Density (g / cm 3 ) = weight (g) / area (cm 2 ) / Thickness(cm)

[0021] The content of the paper used in this 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 material. When the content of the paper is within this range, the original flavor and aroma can be diluted to an appropriate level without impairing the flavor and aroma. The dry weight in one embodiment is the weight of the residue when the tobacco material is dried at 100°C for 5 hours.

[0022] The paper used in this embodiment is not limited as long as the total content of lignin and hemicellulose is within the above range, and may be, for example, tobacco paper such as wrapper paper, or printing paper such as fine printing paper or medium printing paper. However, from the viewpoint of suppressing the generation of unpleasant odors, uncoated paper or lightly coated paper is preferable. Furthermore, the paper used in this embodiment may or may not contain an aerosol-generating substrate, which will be described later. The amount of the aerosol-generating substrate may be within the range described in the second embodiment, or may be within a range other than the range described above.

[0023] (1-2) Second aspect In a second embodiment, the tobacco segment for heating includes a tobacco material and a paper containing an aerosol-generating substrate as a filler. The aerosol-generating substrate is a material that vaporizes when heated and cools to generate an aerosol, or generates an aerosol by atomization. In this embodiment, the paper containing the aerosol-generating substrate is used, so that the effect of diluting the flavor and taste without reducing the amount of smoke is achieved. As the aerosol-generating substrate, a known one can be used, and examples thereof include polyhydric alcohols such as glycerin, vegetable glycerin, propylene glycol (PG), triethyl citrate (TEC), triacetin, etc. 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, stains, etc. may occur on the tobacco segment, and if it is less than the lower limit, the smoke sensation may be reduced. The aerosol-generating substrate can be added to the paper by impregnation, spraying, etc.

[0024] The content of the paper to which the aerosol-generating base material has been 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.

[0025] The paper used in this embodiment is not limited and may be the paper described in the first embodiment. The density of the paper before the addition of the aerosol-generating substrate used in this embodiment may be in the range described in the first embodiment or in another range. The amount of lignin and hemicellulose contained in the paper used in this embodiment is not limited and may be in the range described in the first embodiment or in another range.

[0026] (1-3) Shape etc. In either embodiment, the shape of the paper is not limited, so long as it is in a shape that is easily mixed with the tobacco material. In one embodiment, the paper is in a sheet, shred, or strand. In a preferred embodiment, the paper and the tobacco material are in the same shape, and in a most preferred embodiment, both the paper and the tobacco material are in shred.

[0027] Furthermore, the paper may contain flavorings such as menthol that are commonly used in the field.

[0028] (2) Tobacco materials Tobacco materials are materials derived from plants of the genus Nicotiana. Specific tobacco materials include tobacco shreds, tobacco powder, tobacco ribs, tobacco stems, tobacco sheets, and strands, which are commonly used in the field. These are used alone or in combination. Among these, tobacco shreds and cut tobacco sheets are preferred from the viewpoints of excellent mixing with paper, not increasing air resistance, contributing to flavor and aroma, and having a highly uniform shape.

[0029] As the leaf tobacco, those belonging to the Nicotiana genus, such as Tabacum and Rustica, can be preferably used. There is no limitation on the variety, and one or more of these leaf tobaccos can be mixed and used. As the mixture, a suitable blend of the above varieties can be used to achieve the desired flavor.

[0030] (3) Manufacturing method The tobacco segments may be produced by any method, for example by mixing the tobacco material with the paper and wrapping the mixture in a wrapper, which may be any wrapper commonly used in the art.

[0031] 2. Non-combustion heating type flavor inhalation product In the present invention, the term "flavor inhalation article" refers to an article for a user to inhale a flavor. Among flavor inhalation articles, those containing tobacco or components derived from tobacco are called "tobacco flavor inhalation articles". Tobacco flavor inhalation articles are broadly classified into "combustion type tobacco flavor inhalation articles" (also simply called "smoking articles") that generate a flavor by combustion, and "non-combustion type tobacco flavor inhalation articles" that generate a flavor without combustion. Furthermore, non-combustion type tobacco flavor inhalation articles are broadly classified into "non-combustion heating type tobacco flavor inhalation articles" that generate a flavor by heating, and "non-combustion non-heating type tobacco flavor inhalation articles" that generate a flavor without heating. The tobacco segment containing the paper of the present invention is suitable for non-combustion heating type tobacco flavor inhalation articles.

[0032] FIG. 2 shows one embodiment of a non-combustion heating type tobacco flavor inhalation article. As shown in the figure, the non-combustion heating type tobacco flavor inhalation article 20 includes a tobacco segment 20A, a cylindrical cooling section 20B having perforations on the circumference, and a filter section 20C. The non-combustion heating type tobacco flavor inhalation article 20 may include other members. The axial length of the non-combustion heating type tobacco flavor inhalation article 20 is not limited, but is preferably 40 to 90 mm, more preferably 50 to 75 mm, and more preferably 50 to 60 mm. m It is more preferable that the length of the circumference of the non-combustion heating type tobacco flavor inhalation article 20 is 16 to 25 mm, more preferably 20 to 24 mm, and further preferably 21 to 23 mm. For example, the length of the tobacco segment 20A may be 20 mm, the length of the cooling section 20B may be 20 mm, and the length of the filter section 20C may be 7 mm. The lengths of these individual members may be appropriately changed depending on the manufacturing suitability, the required quality, and the like. Although FIG. 2 shows an embodiment in which the first segment 25 is disposed, only the second segment 26 may be disposed downstream of the cooling section 20B without disposing the first segment 25.

[0033] 1) Tobacco segment 20A The tobacco filler 21 in the tobacco segment 20A includes the tobacco material and paper. The method of filling the tobacco filler 21 into the wrapper 22 is not particularly limited, and for example, the tobacco filler 21 may be wrapped in the wrapper 22, or the tobacco filler 21 may be filled into a cylindrical wrapper 22. When the tobacco and paper have a longitudinal direction, such as a rectangular shape, they may be filled so that the longitudinal direction is in an unspecified direction within the wrapper 22, or may be filled so that they are aligned in the axial direction of the tobacco segment 20A or in a direction perpendicular thereto. The wrapper 22 may also be made of the paper. When the tobacco segment 20A is heated, the tobacco components, aerosol-generating substrate, and water contained in the tobacco filler 21 are vaporized and inhaled.

[0034] 2) Cooling section 20B The cooling section 20B is preferably constructed of a tubular member. The tubular member may be, for example, a cardboard tube 23 formed by processing cardboard into a cylindrical shape. The cooling section 20B may also be formed by a sheet of thin material that is wrinkled and then pleated, gathered, or folded to form a channel. As such a material, for example, a sheet material selected from the group consisting of polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polylactic acid, cellulose acetate, and aluminum foil may be used. The total surface area of ​​the cooling section 20B is appropriately adjusted taking into account the cooling efficiency, but may be, for example, 300 to 1000 mm 2 / mm. The cooling section 20B is preferably provided with perforations 24. The presence of the perforations 24 allows outside air to be introduced into the cooling section 20B during inhalation. As a result, the vaporized components of the aerosol generated by heating the tobacco segment 21A come into contact with the outside air, and as their temperature drops, they are liquefied, forming an aerosol. The diameter (diameter) of the perforations 24 is not particularly limited, but may be, for example, 0.5 to 1.5 mm. The number of 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 section 20B.

[0035] The cooling section 20B may be rod-shaped with an axial length of, for example, 7 to 28 mm. For example, the axial length of the cooling section 20B may be 18 mm. The cooling section 20B may have a substantially circular axial cross-sectional shape with a diameter of 5 to 10 mm. For example, the diameter of the cooling section may be about 7 mm.

[0036] 3) The filter part 20C The configuration of the filter part 20C is not particularly limited, and may be composed of one or more packed layers. The outside of the packed layers may be wrapped with one or more wrapping papers. The airflow resistance of the filter part 20C can be appropriately changed depending on the amount, material, etc. of the filter packing filled in the filter part 20C. For example, when the filter packing is cellulose acetate fiber, the airflow resistance can be increased by increasing the amount of cellulose acetate fiber filled in the filter part 20C. When the filter packing is cellulose acetate fiber, the packing density of the cellulose acetate fiber is 0.13 to 0.18 g / cm. 3 The airflow resistance is a value measured by an airflow resistance measuring device (product name: SODIMAX, manufactured by SODIM).

[0037] The circumferential length of the filter part 20C is not particularly limited, but is preferably 16 to 25 mm, more preferably 20 to 24 mm, and even more preferably 21 to 23 mm. The axial length of the filter part 20C (horizontal direction in FIG. 2) can be selected from 4 to 10 mm, and is selected so that the airflow resistance is 15 to 60 mmH2O / seg. The axial length of the filter part 20C is preferably 5 to 9 mm, and more preferably 6 to 8 mm. The cross-sectional shape of the filter part 20C is not particularly limited, but can be, for example, a circle, an ellipse, a polygon, etc. In addition, a destructible capsule containing a fragrance, fragrance beads, or a fragrance may be directly added to the filter part 20C.

[0038] The filter part 20C may have a center hole part as the first segment 25. The center hole part is composed of a first packed layer 25a having one or more hollow parts and an inner plug wrapper (inner wrapping paper) 25b that covers the packed layer. The center hole part has a function of increasing the strength of the mouthpiece part. The center hole part may not have an inner plug wrapper 25b and may maintain its shape by thermoforming. The filter part 20C may have a second segment 26. The second segment 26 is composed of a second packed layer 26a and an inner plug wrapper (inner wrapping paper) 26b that covers the packed layer. The second packed layer 26a can be, for example, a rod with an inner diameter of φ5.0 to φ1.0 mm, which is packed with cellulose acetate fibers at a high density and hardened by adding 6 to 20% by weight of a plasticizer containing triacetin to the weight of the cellulose acetate. Since the second packed layer has a high fiber packing density, air and aerosol flow only through the hollow parts during inhalation, and hardly flow through the second packed layer. Since the second filling layer inside the center hole portion is a fiber filling layer, the feel from the outside during use is less likely to cause discomfort to the user.

[0039] The first filling layer 25a and the second filling layer 26a are connected by an outer plug wrapper (outer wrapping paper) 27. The outer plug wrapper 27 can be, for example, a cylindrical paper. The tobacco segment 20A, the cooling section 20B, and the first filling layer 25a and the second filling layer 26a that have already been connected are connected by a mouthpiece lining paper 28. These connections can be made, for example, by applying a glue such as a vinyl acetate glue to the inner surface of the mouthpiece lining paper 28 and wrapping the three components. These components may be connected in multiple separate instances using multiple lining papers.

[0040] The combination of the non-combustion heating type tobacco flavor inhalation article and the heating device for generating an aerosol is particularly referred to as a non-combustion heating type tobacco flavor inhalation system. 3In the figure, the non-combustion heating type tobacco flavor inhalation system includes a non-combustion heating type tobacco flavor inhalation article 20 and a heating device 10 that heats a tobacco segment 20A from the outside.

[0041] The heating device 10 includes a body 11, a heater 12, a metal tube 13, a battery unit 14, and a control unit 15. The body 11 has a cylindrical recess 16, in which the heater 12 and the metal tube 13 are disposed at positions corresponding to the tobacco segment 20A to be inserted. 12 The heater 12 can be a heater using electric resistance, and is heated by being supplied with power from a battery unit 14 in response to an instruction from a control unit 15 that controls temperature. The heat generated by the heater 12 is transferred to the tobacco segment 20A through a metal tube 13 with high thermal conductivity. In the figure, the heating device 10 heats the tobacco segment 20A from the outside, but it may also heat from the inside. The heating temperature by the heating device 10 is not particularly limited, but is preferably 400°C or lower, more preferably 150 to 400°C, and even more preferably 200 to 350°C. The heating temperature refers to the temperature of the heater of the heating device 10. EXAMPLES

[0042] [Comparative Example 1] A tobacco sheet manufactured by a known papermaking method was prepared. The tobacco sheet was filled into a wrapper to form a tobacco segment, and a non-combustion heating type flavor inhalation article was prepared as shown in Figure 2. A smoking test was conducted on the article by 10 well-trained panelists (average age 40 years old).

The same tobacco sheets and papers prepared in Comparative Example 1 were cut into widths of 0.3 to 2.0 mm and lengths of 3 to 50 mm. The cut pieces of paper and the cut pieces of tobacco sheets were mixed in a weight ratio of 80:20, and non-combustion heating type flavor inhalation articles were prepared in the same manner as in Comparative Example 1, and subjected to a smoking test. Using the results of Comparative Example 1 as the standard, the flavor and smoke volume were evaluated according to the following criteria. 1: Greatly reduced 2: Decrease 3: Unchanging (standard) 4: Increase 5: Greatly Increased

[0044] The textile odor was evaluated according to the following criteria. 1: None (standard) 2: Very low 3: Low 4: Moderate 5: Strong

[0045] [Table 1]

[0046] [Example 2, Comparative Example 3] A non-combustion heating-type flavor inhalation article was prepared in the same manner as in Example 1, except that the tobacco sheet and material 5 were blended in the amounts shown in Table 2, and a smoking test was carried out.

[0047] [Table 2]

[0048] [Example 3] The tobacco sheet and material 5 were blended in the amounts shown in Table 3. However, 10% by weight of glycerin was added to material 5 as an aerosol-generating base material based on the dry weight. A non-combustion heating-type flavor inhalation article was prepared in the same manner as in Example 1 except that the blend was used, and a smoking test was performed.

[0049] [Table 3]

[0050] [Quantitative determination of hemicellulose] 1) Place the paper in a Thermo Scientific TM Dionex TM ASE TM The residue was separated by solvent extraction (solvent: water) using an accelerated solvent extraction system (model number: ASE-350). The residue was freeze-pulverized using liquid nitrogen or the like to obtain sample A. 2) 50 mg of sample A was placed in a screw bottle, 8.5 ml of ultrapure water (ML-Q water) and 0.5 ml of pancreatin solution were added, and the mixture was shaken at 40°C and 125 rpm for 16 hours. The sample liquid was then transferred to a 15 ml centrifuge tube using ML-Q water, centrifuged at 8000 rpm for 15 minutes, and the supernatant was removed. This washing was repeated three times. After washing, 10 ml of 5% sulfuric acid aqueous solution was added, and hydrolysis was performed at 100°C for 2.5 hours. After the hydrolysis reaction was completed, the sample was allowed to cool to room temperature. The precipitate was then filtered off, and the filtrate was collected in a 250 ml measuring flask. The residue on the filter paper was thoroughly washed with ML-Q water, and the volume was adjusted to 250 ml. This solution was used as a sample for measuring hemicellulose. 3) 500 μl of the sample was transferred to a 20 ml test tube, 500 μl of 5% phenol solution and 2.5 ml of concentrated sulfuric acid were added, and the mixture was stirred vigorously for 10 seconds. The sample was left at room temperature for 20 minutes or more, and the absorbance was measured at a wavelength of 490 nm using a spectrophotometer to quantify the hemicellulose.

[0051] [Quantitative determination of lignin] i) The above-mentioned sample A was prepared. ii) 100 mg of sample A was placed in a screw bottle, 4 ml of 72% sulfuric acid was added, and the sample was completely immersed in the sulfuric acid and shaken at 30°C and 200 rpm for 4 hours. Next, 157.2 ml of ultrapure water (ML-Q water) was added so that the sulfuric acid concentration after dilution was 4%, and the sample was transferred to an eggplant flask and heated to reflux in a 110°C oil bath for 2 hours. iii) The refluxed product was allowed to cool to room temperature, filtered, dried in a rotary dryer, and weighed to obtain the lignin content.

[0052] It is clear that the tobacco segments of the present invention can appropriately dilute the flavor and taste. [Explanation of symbols]
