(A) (Lip release agent content per unit area in the first region) > (Lip release agent content per unit area in the second region)
An example of the non-combustible heated tobacco according to the above embodiment is shown in FIG. Hereinafter, the non-combustible heated cigarette will be explained with reference to FIG. 1. In Figure 1, it is shown that the lip release agent is applied to the entire one side of the chip paper at a uniform concentration, but there is no such limitation, and there are differences in the concentration depending on the area where it is applied. It's fine. This also applies to other figures.
The direction h in FIG. 1 is the long axis direction of the non-combustion heated tobacco.

It is preferable that the non-combustible heated tobacco has a columnar shape that satisfies a shape with an aspect ratio defined as below of 1 or more.
Aspect ratio = h/w
w is the width of the bottom surface of the columnar body (in this specification, it is the width of the bottom surface on the tobacco rod side), h is the height, and it is preferable that h≧w. However, in this specification, as described above, the major axis direction is defined as the direction indicated by h. Therefore, even when w≧h, the direction indicated by h is called the long axis direction for convenience. The shape of the bottom is not limited and may be a polygon, a rounded polygon, a circle, an ellipse, etc., and the width w is the diameter if the bottom is circular, the major axis if it is an ellipse, or the polygon or rounded polygon. In some cases, it is the diameter of the circumscribed circle or the major axis of the circumscribed ellipse. For example, in the embodiment shown in FIG. 1, since the bottom surface is a circle, its diameter can be determined. The diameter is the width w, and the length perpendicular to this is the height h.

Each component of the non-combustible heated cigarette will be explained below.

<1-1. Winding section>
[First region and second region of wrapping section]
As shown in FIG. 1, the wrapping portion in which the tobacco rod portion 10 and the mouthpiece portion 11 are wrapped with tip paper 12 includes a first region 12a and a second region 12b. Although not shown in FIG. 1, the tobacco rod portion 10 is made by wrapping tobacco filling with wrapping paper, as will be described later. Furthermore, the chip paper is coated with a lip release agent 13 at least in part.
The first region 12a is a region that includes the mouth end of the non-combustion heated cigarette in the longitudinal direction of the non-combustible heated cigarette, and the second region 12b is a region that is wider than the first region. This is a region located on the tobacco rod part side of the wrapping part. The first region and the second region are adjacent regions.
In FIG. 1, the lip release agent in the first region is a portion indicated by 13a, and the lip release agent in the second region is a portion indicated by 13b.
The content of lip release agent per unit area in the first region is also simply referred to as "the amount of lip release agent in the first region", and the content of lip release agent per unit area in the second region is also referred to as "amount of lip release agent in the first region". , also simply referred to as "the amount of lip release agent in the second region".

In conventional non-combustible heated cigarettes, the entire surface of the tip paper is usually coated with a lip release agent, and the concentration of the lip release agent is varied within the surface, that is, the above condition (A) is satisfied. Lip release agents are not applied to the skin. In this case, although the lip release property that is the purpose of applying the lip release agent is achieved, during use, substances derived from the lip release agent generated by heating are generated from the entire surface of the chip paper.
On the other hand, when the lip release agent is applied so as to satisfy the above condition (A), the lip release agent in the first region not only achieves lip release properties but also improves the lip release properties in the second region. Since the amount of lip release agent is smaller than the amount of lip release agent in the first region, the amount of lip release agent-derived substances generated during use is reduced compared to the above-mentioned conventional non-combustion heated tobacco. Note that at least a part of the chip paper is coated with a lip release agent, but from the viewpoint of ensuring lip release properties, the lip release agent coated portion is a filter section described below that can be provided in the mouthpiece section. It is preferable that at least a part of the region of the chip paper located directly below is coated, and it is also a preferable embodiment that the entire surface of that region is coated.
Although the aspects of the first region and the second region are not particularly limited, particularly preferred aspects will be described below.

(1) First aspect A first aspect of the first region and the second region is such that the first region extends from the mouth end of the non-combustible heated cigarette in the longitudinal direction of the non-combustible heated cigarette. This embodiment is characterized in that it is a region up to a position of 17 mm, and the second region is a region from the 17 mm position to an end on the tobacco rod side in the longitudinal direction of the wrapping part.
In the general usage mode of non-combustible heated cigarettes, if a lip release agent is coated on the first region, which is the area 17 mm from the mouth end of the non-combustible heated cigarette, the By considering the contact area between the smoker's lips and the non-combustible heated cigarette (also referred to as the "lip contact area"), sufficient lip release properties can be ensured. Furthermore, the 17
By reducing the amount of lip release agent applied in the second region, which is the region from the position of mm to the end of the tobacco rod in the longitudinal direction of the wrapping part, the generation of substances derived from the lip release agent during use is reduced. The amount can be reduced.

The position from the mouth end of the non-combustible heated cigarette that separates the first region and the second region can be set to 17 mm for the above reasons, but substances derived from the lip release agent are generated during use. From the viewpoint of being able to reduce the amount, it is preferably 15 mm, more preferably 13 mm, and particularly preferably 10 mm. If the position is brought closer to the mouthpiece end side, it becomes difficult to ensure lip release properties.

(2) Second aspect A second aspect of the first area and the second area is that the first area The region extends from the mouth end of the non-combustion heating type cigarette to a 42.5% position, and the second region extends from the 42.5% position to the end of the tobacco rod in the longitudinal direction of the wrapping part. This is an aspect characterized by being in the area of .
Similar to the first aspect above, considering the general usage of non-combustion heated cigarettes, the length of the wrapping part in the long axis direction of the non-combustion heated cigarette is If the lip release agent is coated on the first area, which is the area 42.5% from the end of the mouthpiece side of the formula cigarette, sufficient lip release properties can be ensured. The amount of substances derived from lip release agents can be reduced.

For the reasons stated above, the ratio from the mouth end of the non-combustible heated cigarette to the length of the wrapping part in the longitudinal direction of the non-combustible heated cigarette that separates the first region and the second region is determined. It can be 42.5%, but from the viewpoint of reducing the amount of substances derived from lip release agents during use, it is preferably 37.5%, and 32.5% is preferable. More preferably, it is particularly preferably 25%. If the position is brought closer to the mouthpiece end side, it becomes difficult to ensure lip release properties.

(3) Third Aspect The mouthpiece section of the non-combustible heated cigarette according to this embodiment may include a cooling section and a filter section. A third aspect of the first region and the second region, which is a possible aspect in this case, is that the cooling section has a plurality of openings, and the plurality of openings are formed on the outer peripheral surface of the cooling section. The first region is arranged in the circumferential direction, and the first region extends from the mouth end of the non-combustible heated cigarette to the arrangement position of the opening with respect to the length of the wrapping part in the longitudinal direction of the non-combustible heated cigarette. This embodiment is characterized in that the second region is a region from the arrangement position of the opening to the tobacco rod side end in the longitudinal direction of the wrapping portion.
The openings in the cooling section make it possible to control the air and smoke flow in the cooling section and filter section by introducing diluted air from the openings to the suction end side during use. . Generally, a region closer to the mouth end than the position where the opening is provided becomes the lip contact region. In other words, if the lip release agent is applied to the region closer to the mouth end than the opening position, sufficient lip release properties can be ensured. As described in the first aspect above, by reducing the amount of lip release agent applied in the second region, it is possible to reduce the amount of substances derived from the lip release agent generated during use. In particular, the flow of air and smoke in the mouthpiece changes around the aperture position, and the temperature of the winding on the mouth end side of the aperture increases, while the temperature of the winding on the tobacco rod side of the aperture changes. By reducing the content of lip release agent in the wrapping on the tobacco rod side than the opening position, the amount of lip release agent-derived substances is greatly reduced. can be done.
The above-mentioned apertures are sometimes referred to in the art as "ventilation apertures."

The openings are arranged in the circumferential direction of the outer peripheral surface of the cooling section (specifically, they are arranged on a plane perpendicular to the long axis direction of the non-combustion heated tobacco in the cooling section), The number of arrangement (also referred to as "circumferential arrangement") is not particularly limited, and two or more may exist, but in this case, generally the circumferential arrangement is provided in the lip contact area. Since it is on the outside, the circumferential arrangement that forms the boundary between the first region and the second region is the circumferential arrangement that is closest to the mouthpiece end.
The position of the opening is not particularly limited, but from the viewpoint of reducing the amount of substances derived from the lip release agent generated during use, it is determined that the length of the wrapping part in the longitudinal direction of the non-combustible heating tobacco On the other hand, it is preferably 17 mm from the mouth end of the non-combustible heating type cigarette, more preferably 15 mm, even more preferably 13 mm, and particularly preferably 10 mm.

[Tip paper]
The material of the chip paper 12 constituting the winding part is not particularly limited, and paper made from common vegetable fibers (pulp) or chemical fibers made from polymers (polypropylene, polyethylene, nylon, etc.) may be used. A plastic sheet, a polymer sheet, a metal foil such as aluminum foil, etc. can be used. Note that the tip paper here refers to a sheet that connects a plurality of segments in a non-combustible heated cigarette, such as connecting a tobacco rod part and a mouthpiece part.

The method for producing chip paper is not particularly limited, and general methods can be applied. For example, in the case of an embodiment in which pulp is the main component, the pulp is used in a Fourdrinier paper machine, a cylinder paper machine, a circle paper machine, etc. In the paper making process using a short combined paper machine, etc., there is a method of adjusting and making the texture uniform. Note that, if necessary, a wet paper strength enhancer may be added to impart water resistance to the wrapping paper, or a sizing agent may be added to adjust the printing quality of the wrapping paper. Furthermore, internal additives for paper making such as sulfuric acid, various anionic, cationic, nonionic, or amphoteric retention improvers, freeness improvers, and paper strength enhancers, as well as dyes, pH adjusters, Papermaking additives such as antifoaming agents, pitch control agents, and slime control agents can be added.
In addition to pulp made from wood pulp such as softwood pulp and hardwood pulp, non-wood pulp such as flax pulp, hemp pulp, sisal pulp, and espart, which are commonly used for wrapping paper for smoking articles, are mixed. It may also be obtained by manufacturing. Further, as the type of pulp, chemical pulps produced by kraft cooking method, acidic/neutral/alkaline sulfite cooking method, soda salt cooking method, etc., ground pulp, chemical ground pulp, thermomechanical pulp, etc. can be used.

<1-2. Lip release agent>
Considering ease of analysis and actual solid content, the solid content of the lip release agent in this embodiment may be 100% nitrocellulose, or 100% ethylcellulose. Alternatively, a mixture of these in any proportion may be used. Moreover, the solid content of the lip release agent may be a mixture further containing components other than nitrocellulose and/or ethylcellulose.
Until now, no studies have been conducted on the effects of lip release agents on the smoking taste of non-combustible heated cigarettes. The present inventor prepared a non-combustible heated cigarette having a wrapper whose entire surface was coated with a lip release agent, and a non-combustible heated cigarette that satisfies the above condition (A). An experiment was conducted to compare the TSNA content of both types of cigarettes. As a result, non-combustible heated cigarettes with a wrapper coated with a lip release agent on the entire surface contained more TSNA than non-combustible heated cigarettes that met condition (A). I understand. The inventor considered the cause as follows.
A typical component used in lip release agents is nitrocellulose, which is a nitrate ester of cellulose. Nitrocellulose is usually obtained by treating cellulose with a mixed acid of nitric acid and sulfuric acid. This nitrocellulose was decomposed by heating to produce nitric acid, and TSNA was produced by the reaction of the nitric acid with minor alkaloids in the tobacco raw material. Non-combustible heated cigarettes that have a wrapper coated entirely with a lip release agent have a lower lip release agent content than non-combustible heated cigarettes that have a wrapper partially coated with a lip release agent. The heated area becomes wider. Therefore, the heat from the heater was transmitted directly or indirectly to the lip release agent, and a portion of the lip release agent was heated excessively, which is thought to have resulted in the above result.
Note that TSNA is a general term for tobacco-specific nitrosamines, including N'-nitrosonornicotine (NNN), 4-(N-nitrosomethylamino)-1-(3-pyridyl)-1-butanone (NNK) , N'-nitrosoanatabine (NAT), and N'-nitrosoanabasine (NAB).

When lip release agents contain nitrocellulose, TSNA is generated as mentioned above, but in addition to nitrocellulose, there are other ingredients in lip release agents that may generate substances that may have an undesirable effect on the taste, etc. contained in the drug. For example, ethyl cellulose, which can be used in lip release agents, may cause undesirable changes in taste and the like.
The materials contained in the lip release agent in this embodiment are not particularly limited, and examples thereof include nitrocellulose, ethylcellulose, and mixtures thereof, but from the viewpoint of suppressing the generation of TSNA, nitrocellulose is included. This is particularly advantageous for lip release agents.

The lip release agent may contain components other than the above-mentioned nitrocellulose and ethylcellulose, and for example, fillers such as calcium carbonate can be used. Commercially available products can be used as the components of these lip release agents.

The method of applying the lip release agent to the chip paper is not particularly limited, and a general application method can be applied. The lip release agent can usually be used as a 1.0 to 30.0% by weight aqueous solution or ethyl acetate solution, and such an aqueous solution or ethyl acetate solution can be used by using an appropriate printing method such as gravure printing. Accordingly, the chipping paper according to the embodiment of the present invention can be coated. The lip release agent may be applied to the chip paper according to the embodiment of the present invention by known means other than printing, such as applying an opaque ink by inkjet printing, spraying, or impregnation.
Further, the lip release agent needs to be coated on at least a part of the outer surface of the first region of the tip paper, but may also be coated on the inner surface. However, from the viewpoint of reducing the amount of substances derived from the lip release agent generated during use, it is preferable that the lip release agent is not coated on the inner surface of the chip paper.

[Lip release agent content]
The content of the lip release agent satisfies condition (A) as described above.
By satisfying the condition (A), lip release properties are ensured, and the generation of substances derived from the lip release agent during use is reduced, reducing the amount of substances generated that have an undesirable effect on the smoking taste. Can be suppressed.
The ratio of the content of the lip release agent per unit area in the second region to the content of the lip release agent per unit area in the first region is not particularly limited. From the viewpoint of reducing the amount of generated substances derived from lip release agents, it is preferably 1/2 or less, more preferably 1/4 or less, particularly preferably 1/6 or less, and 1/8 or less. Most preferably.

The content of lip release agent per unit area in the first region is not particularly limited as long as it is higher than the content of lip release agent per unit area in the second region, but is usually 0.20 μg/mm ² or more, It is 1.00 μg/mm ² or less, preferably 0.25 μg/mm ² or more and 0.75 μg/mm ² or less.

The content of lip release agent per unit area in the second region is not particularly limited, but from the viewpoint of reducing the amount of lip release agent-derived substances generated during use, the amount of lip release agent-derived substances generated during use is From the viewpoint of reduction, it is preferably less than 0.56 μg/mm ² , more preferably less than 0.28 μg/mm ² , particularly preferably less than 0.14 μg/mm ² , and particularly preferably less than 0 μg/mm ² It is most preferable that the material is , that is, not coated.
The method for measuring the content of the lip release agent is not particularly limited, but for example, after peeling off the chip paper constituting the wrapping part from a non-combustible heated cigarette, cutting it into a first region and a second region. After separating them, measure their weight, subtract the weight of the tip paper in each area to calculate the coated weight of lip release agent, and divide these by the area of each area to calculate the weight of the first area and The content of lip release agent per unit area in the second region can be determined.
In addition, if it is possible to calculate, calculate the coating weight of the lip release agent divided by the area at the time of manufacture or the coating weight calculated from the difference in weight of chip paper before and after applying the lip release agent to the target area. The value divided by the area of may also be used.
Since lip release agents have the property of turning brown when heated to a certain level, a simple way to estimate the level of lip release agent content is to measure the surface of the tip paper before and after using a non-combustible heated cigarette. A method of observing the degree of discoloration can be adopted.

Moreover, the content of the lip release agent can be measured by spectrophotometry. For example, when nitrocellulose is used as a lip release agent, a value calculated by the following method can be used.
First, a standard sample for the calibration curve was prepared using the method shown below, and the absorbance was measured.
In accordance with D3133-01, a calibration curve is created from the absorbance measurement results of the calibration curve standard sample. Then, a measurement sample is prepared by the method shown below, and the absorbance is measured. From the above calibration curve and the results of absorbance measurement of the measurement sample, the content weight of nitrocellulose in the measurement sample can be determined, and by dividing this by the area of the target area, coating of the lip release agent in the target area can be determined. You can find the quantity.

<1-3. Tobacco rod section＞
The structure of the tobacco rod section 10 is not particularly limited and can be of a general form. For example, a tobacco filling wrapped in wrapping paper can be used.

[Tobacco filling]
The composition of the tobacco filler is not particularly limited, but it may be composed of a composition containing shredded tobacco (hereinafter also referred to as the first tobacco filler), or it may be composed of a plurality of tobacco sheets described below (hereinafter referred to as the first tobacco filler). , a second tobacco filling), or a single tobacco sheet (hereinafter also referred to as a third tobacco filling).
The tobacco rod portion (herein also simply referred to as “tobacco rod”) preferably has a columnar shape, and in this case, the longitudinal direction of the tobacco rod portion with respect to the width of the bottom surface of the tobacco rod portion. It is preferable that the aspect ratio expressed by the height of is 1 or more.
The shape of the bottom surface of the tobacco rod part is not limited and may be a polygon, a rounded polygon, a circle, an ellipse, etc., and the width is the diameter if the bottom is circular, the major axis if the bottom is oval, and the polygon or corner. If it is a round polygon, it is the diameter of the circumscribed circle or the major axis of the circumscribed ellipse. For example, in the embodiment shown in FIG. 1, since the bottom surface is a circle, its diameter can be determined. The diameter is the width, and the length perpendicular to this is the height. It is preferable that the tobacco filler constituting the tobacco rod portion has a height of about 12 to 70 mm and a width of about 4 to 9 mm.
The tobacco rod portion may have a fitting portion for a heater member or the like for heating the non-combustible heated tobacco.

First, the first filling will be explained. The material of the shredded tobacco contained in the first filling is not particularly limited, and known materials such as lamina and backbone can be used. Alternatively, dried tobacco leaves may be pulverized and homogenized to have an average particle size of 20 to 200 μm, processed into a sheet (hereinafter also simply referred to as a homogenized sheet), and then shredded. Furthermore, a so-called strand type may be used in which the tobacco rod is filled with a homogenized sheet having a length comparable to the longitudinal direction of the tobacco rod and cut approximately horizontally to the longitudinal direction of the tobacco rod. . The width of the shredded tobacco is preferably 0.5 to 2.0 mm for filling the tobacco rod portion. In the case of a tobacco rod having a circumference of 22 mm and a length of 20 mm, the content of the tobacco filler in the tobacco rod may be 200 to 800 mg/rod, preferably 250 to 600 mg/rod. Various types of tobacco can be used for the tobacco leaves used in the tobacco shredding and production of the homogenized sheet. Examples include yellow varieties, burley varieties, orient varieties, native varieties, other Nicotiana tabacum varieties, Nicotiana rustica varieties, and mixtures thereof. As for the mixture, the above-mentioned varieties can be appropriately blended and used so as to obtain the desired taste. Details of the tobacco varieties are disclosed in "Tobacco Encyclopedia, Tobacco Research Center, March 31, 2009." There are a number of conventional methods for producing the homogenized sheet, that is, a method for pulverizing tobacco leaves and processing them into a homogenized sheet. The first method is to produce a paper sheet using a papermaking process. The second method is to mix an appropriate solvent such as water with crushed tobacco leaves and homogenize them, then cast a thin layer of the homogenized product onto a metal plate or metal plate belt, and dry it to form a cast sheet. This is a method of manufacturing. The third method is to prepare a rolled sheet by mixing an appropriate solvent such as water with crushed tobacco leaves, homogenizing the mixture, and extruding the mixture into a sheet shape. Details of the types of the homogenizing sheet are disclosed in "Tobacco Encyclopedia, Tobacco Research Center, March 31, 2009."

The moisture content of the tobacco filling can be 10 to 15% by weight, preferably 11 to 13% by weight, based on the total amount of the tobacco filling. Such a moisture content suppresses the occurrence of winding stains and improves the winding suitability during manufacturing of the tobacco rod portion.
There are no particular restrictions on the size of the shredded tobacco contained in the first tobacco filling or the method for preparing it. For example, dried tobacco leaves chopped to a width of 0.5 to 2.0 mm may be used.
When using a pulverized homogenized sheet, dry tobacco leaves are pulverized and homogenized to an average particle size of about 20 to 200 μm, then processed into a sheet with a width of 0.5 to 2.0 μm. You may use one cut to 0 mm.

The first tobacco fill includes an aerosol-generating substrate that generates aerosol smoke. The type of the aerosol-generating base material is not particularly limited, and extracts from various natural products and/or their constituent components can be selected depending on the purpose. Aerosol generating substrates can include glycerin, propylene glycol, triacetin, 1,3-butanediol, and mixtures thereof.

Further, these fragrances may be used alone or in combination of two or more.

The content of the flavoring agent in the first tobacco filling is not particularly limited, and from the viewpoint of imparting good smoking taste, it is usually 10,000 ppm or more, preferably 20,000 ppm or more, more preferably 25,000 ppm or more, and , usually 50,000 ppm or less, preferably 40,000 ppm or less, and more preferably 33,000 ppm or less.

The packing density of the first tobacco filling is not particularly limited, but is usually 250 mg/cm ³ or more, preferably 320 mg/cm from the viewpoint of ensuring the performance of the non-combustible heated tobacco and imparting good smoking taste. ³ or more, and usually 800 mg/cm ³ or less, preferably 600 mg/cm ³ or less.
The first tobacco filling is wrapped with wrapping paper so that it is on the inside to form a tobacco rod portion.

The second tobacco filler is composed of a plurality of concentrically arranged tobacco sheets. As used herein, "arranged concentrically" means that the centers of all the cigarette sheets are arranged at approximately the same position. In this specification, the term "sheet" refers to a shape having a pair of substantially parallel main surfaces and side surfaces. The second filling is formed by winding a plurality of tobacco sheets concentrically in a direction perpendicular to the longitudinal direction of the non-combustible heated tobacco.
Examples of the sheet base material include tobacco materials such as tobacco powder, and tobacco materials are particularly preferred. It is preferable that the tobacco sheet is a base sheet of tobacco material, which carries a component capable of producing flavor as required. Tobacco sheets generate aerosol as they are heated. Aerosol sources such as glycerin, propylene glycol, polyols such as 1,3-butanediol, etc. can be added as aerosol generating substrates. The amount of such aerosol-generating base material added is preferably 5 to 50% by weight, more preferably 15 to 25% by weight, based on the dry weight of the tobacco sheet.

A cigarette sheet as a material before being concentrically arranged will be explained.
Tobacco sheets can be appropriately manufactured by known methods such as paper forming, slurry, rolling, etc. Note that the homogenizing sheet described in the first tobacco filling can also be used.
In the case of papermaking, it can be manufactured by a method including the following steps. 1) Roughly crush dried tobacco leaves, extract with water, and separate into water extract and residue. 2) Dry and concentrate the aqueous extract under reduced pressure. 3) Add pulp to the residue, turn it into fibers using a refiner, and then make paper. 4) A concentrated solution of water extract is added to the paper sheet and dried to obtain a tobacco sheet. In this case, a step of removing some components such as nitrosamines may be added (see Japanese Patent Publication No. 2004-510422).
In the case of the slurry method, it can be manufactured by a method including the following steps. 1) Mix water, pulp and binder with crushed tobacco leaves. 2) Spread (cast) the mixture thinly and dry. In this case, a step may be added in which some components such as nitrosamines are removed by irradiating ultraviolet rays or X-rays to a slurry of water, pulp, binder, and crushed tobacco leaves.

In addition, as described in International Publication No. 2014/104078, a nonwoven tobacco sheet manufactured by a method including the following steps can also be used. 1) Mix powdered tobacco leaves and a binder. 2) Sandwich the mixture between nonwoven fabrics. 3) The laminate is formed into a certain shape by heat welding to obtain a nonwoven tobacco sheet.
The types of tobacco leaves used as raw materials in each of the above methods can be the same as those described for the first filling.
Although the composition of the tobacco sheet is not particularly limited, for example, the content of tobacco raw material (tobacco leaves) is preferably 50 to 95% by weight based on the total weight of the tobacco sheet. Further, the tobacco sheet may contain a binder, and examples of such binders include guar gum, xanthan gum, CMC (carboxymethylcellulose), CMC-Na (sodium salt of carboxymethylcellulose), and the like. The amount of binder is preferably 1 to 20% by weight based on the total weight of the tobacco sheet. The tobacco sheet may further contain other additives. Examples of additives include fillers such as pulp. Although a plurality of tobacco sheets are used herein, all of the tobacco sheets may have the same composition or physical properties, or some or all of the tobacco sheets may have different compositions or physical properties.

The second tobacco filling is made by preparing a plurality of tobacco sheets with different widths, stacking them so that the width decreases from the bottom to the top, and passing this through a winding tube and rolling it up. It can be manufactured by According to this manufacturing method, the plurality of tobacco sheets extend in the longitudinal direction and are arranged concentrically about the longitudinal axis. Further, a fitting portion extending in the longitudinal direction may be formed between the longitudinal axis and the innermost tobacco sheet.
In this manufacturing method, the laminate is preferably prepared such that a non-contact portion is formed between the adjacent tobacco sheets after winding.
If there is a non-contact part (gap) between the plurality of tobacco sheets where the tobacco sheets do not come into contact with each other, a flavor flow path can be ensured and the delivery efficiency of flavor components can be increased. On the other hand, since the heat from the heater can be transferred to the outer tobacco sheets through the contact portions of the plurality of tobacco sheets, high heat transfer efficiency can be ensured.

In order to provide a non-contact part between a plurality of tobacco sheets where the tobacco sheets do not come into contact, for example, embossed tobacco sheets are used, adjacent tobacco sheets are laminated without adhering their entire surfaces, or adjacent tobacco sheets are used. Examples include methods of preparing a laminate by gluing and laminating parts of adjacent cigarette sheets, or laminating all or part of adjacent cigarette sheets by lightly adhering them so that they can be peeled off after winding and forming. .
When preparing a tobacco rod portion including wrapping paper, the wrapping paper may be placed at the bottom of the laminate.
Alternatively, the fitting portion can be formed by placing a cylindrical dummy such as a mandrel on the top of the stack to form the second tobacco filling, and then removing the dummy.
Although the thickness of each tobacco sheet is not limited, it is preferably 200 to 600 μm in view of the balance between heat transfer efficiency and strength. The thickness of each tobacco sheet may be the same or different.
The number of tobacco sheets constituting the second tobacco filling is not particularly limited, and may be, for example, 2, 3, 4, 5, or 6 sheets.

The third tobacco filler consists of a single folded tobacco sheet. The sheet may be a so-called gathered sheet that has a length comparable to the longitudinal direction of the tobacco rod portion and is folded back and filled multiple times horizontally to the longitudinal direction of the tobacco rod portion. The thickness of the sheet is preferably 200 to 600 μm from the viewpoint of heat transfer efficiency and strength.
As the sheet base material used for the third tobacco filling material, the same material as the second tobacco filling material can be used.

[Wrapping paper]
The structure of the wrapping paper is not particularly limited, and a general one can be used. For example, as the base paper used for the wrapping paper, cellulose fiber paper can be used, and more specifically, hemp, wood, or a mixture thereof can be mentioned. Note that the "wrapping paper" used here is for wrapping the tobacco filling.
The wrapping paper may contain a filler, and the type of filler is not limited, and may include metal carbonates such as calcium carbonate and magnesium carbonate, metal oxides such as titanium oxide and aluminum oxide, barium sulfate, calcium sulfate, etc. Examples include metal sulfates, metal sulfides such as zinc sulfide, quartz, kaolin, talc, diatomaceous earth, gypsum, etc., and in particular, calcium carbonate is included from the viewpoint of improving whiteness and opacity and increasing heating rate. It is preferable.
The blending ratio of filler in the wrapping paper is not particularly limited, and is usually 1 to 50 wt%, preferably 5 to 45 wt%, more preferably 10 to 42 wt%, and 20 to 40 wt%. It is particularly preferable that Note that, for example, when determining the content of calcium carbonate, it can be determined by measuring the ash content or by quantifying calcium ions after extraction.
If it is less than the lower limit of the above range, the wrapping paper will be likely to burn, while if it exceeds the upper limit, the strength of the wrapping paper will be greatly reduced and the winding properties may deteriorate.

Various auxiliary agents other than base paper and filler may be added to the wrapping paper. For example, in order to improve water resistance, a water resistance improver may be added. Water resistance improvers include wet paper strength agents (WS agents) and sizing agents. Examples of wet paper strength agents include urea formaldehyde resin, melamine formaldehyde resin, and polyamide epichlorohydrin (PAE). Examples of sizing agents include rosin soap, alkyl ketene dimer (AKD), alkenyl succinic anhydride (ASA), and highly saponified polyvinyl alcohol with a saponification degree of 90% or more.
A paper strength enhancer may be added as an auxiliary agent, and examples thereof include polyacrylamide, cationic starch, oxidized starch, CMC, polyamide epichlorohydrin resin, polyvinyl alcohol, and the like. In particular, it is known that using a very small amount of oxidized starch improves air permeability (Japanese Patent Laid-Open No. 2017-218699).
Moreover, the wrapping paper may be appropriately coated.

A coating agent may be added to at least one of the front and back sides of the wrapping paper. Although there are no particular limitations on the coating agent, a coating agent that forms a film on the surface of paper and can reduce liquid permeability is preferred. Examples include alginic acid and its salts (e.g. sodium salt), polysaccharides such as pectin, cellulose derivatives such as ethylcellulose, methylcellulose, carboxymethylcellulose, nitrocellulose, starch and its derivatives (e.g. carboxymethyl starch, hydroxyalkyl starch and cationic starch). ester derivatives such as starch acetate, starch phosphate and starch octenylsuccinate).

The basis weight of the wrapping paper is usually 20 to 45 g/m ² , preferably 25 to 40 g/m ² . Within this range, appropriate strength and winding properties can be maintained.
The air permeability of the wrapping paper is usually 0 to 120 Coresta units, preferably 5 to 100 Coresta units, and more preferably 10 to 80 Coresta units. Within this range, appropriate strength and flavor can be maintained.

<1-4. Mouthpiece section＞
The configuration of the mouthpiece portion 11 is not particularly limited, and can be of a general configuration. For example, as shown in FIG. 3, it may include a cooling section 15 and a filter section 16, or these may be used in combination.

[Cooling section]
The configuration of the cooling unit is not particularly limited as long as it has the function of cooling mainstream tobacco smoke, and for example, a configuration made of cardboard processed into a cylindrical shape may be used. In this case, the cylindrical interior is hollow, and the vapor containing the aerosol-generating substrate and tobacco flavor component is cooled by contacting the air within the cavity.

As shown in FIG. 3, the non-combustible heated tobacco 1 has holes (not shown) for introducing air from the outside in the cooling part 15 and a part of the tip paper 12 that can be covered with a lip release agent. It may have. The presence of such openings allows air to flow into the cooling section 15 from the outside during use, and vapor containing the aerosol-generating base material and tobacco flavor components generated by heating the tobacco rod section. When it comes into contact with air from the outside and its temperature drops, it liquefies and can promote the generation of aerosol. As shown in FIG. 4, when the cooling unit 15 has a plurality of openings 18, as described in the third aspect of “1-1. A plurality of openings 18 are arranged in the circumferential direction of the outer peripheral surface of the cooling part 15. The number of circumferential arrangements is not particularly limited, and two or more may be present. Although the cooling section in FIG. 4 has a cylindrical shape with a cavity 17, it is not limited to this shape. Further, in FIG. 4, the boundary between the first region and the second region is omitted.
The diameter of the openings is preferably 100 to 1000 μm, more preferably 300 to 800 μm. It is preferable that the opening is approximately circular or approximately elliptical, and in the case of approximately elliptical, the diameter represents the major axis.

As shown in FIG. 4, the chip paper 12 and the lip release agent 13 may have holes so that the openings of the cooling section pass through them, or they may not have holes, but the cooling effect may be reduced. From the viewpoint of promotion, it is preferable to have pores.
Furthermore, as described in the third aspect of "1-1. Winding section" above, the openings are arranged in the circumferential direction of the outer circumferential surface of the cooling section, (also referred to as "circumferential arrangement") is not particularly limited, and two or more may exist, but in this case, the circumferential arrangement is generally provided outside the lip contact area. The circumferential arrangement that forms the boundary between the first region and the second region is the circumferential arrangement that is closest to the mouth end.
Further, the inside of the cooling section may be filled with gathered sheet-shaped members such as paper, polymer film, or metal foil. In this case, the steam can also be cooled using the specific heat of these members.
The height of the cooling part in the long axis direction is not particularly limited, but from the viewpoint of ensuring the cooling function, it is usually 5 to 40 mm, preferably 10 to 35 mm, and more preferably 15 to 30 mm.

[Filter section]
The structure of the filter section 16 is not particularly limited as long as it has a function as a general filter, and for example, it may be formed by processing cellulose acetate tow into a columnar shape. The single fiber fineness and total fineness of cellulose acetate tow are not particularly limited, but in the case of a filter section with a circumference of 22 mm, the single fiber fineness is preferably 5 to 12 g/9000 m, and the total fineness is 12000 to 30000 g/9000 m. The cross-sectional shape of the cellulose acetate tow fibers may be either a Y cross-section or an R cross-section. In the case of a filter filled with cellulose acetate tow, triacetin may be added in an amount of 5 to 10% by weight based on the weight of the cellulose acetate tow in order to improve filter hardness.
In FIG. 3, the filter section 16 is composed of a single segment, but it may be composed of a plurality of segments. If it is composed of multiple segments, for example, a hollow segment such as a center hole is placed on the upstream side (tobacco rod side), and the downstream segment (on the user's mouth end side) has a cross section of cellulose acetate tow. An embodiment of arranging a filled acetate filter can be mentioned. According to such an aspect, it is possible to prevent unnecessary loss of the generated aerosol and to improve the appearance of the non-combustible heated cigarette. Furthermore, from the viewpoint of changes in the sensation of sucking response and comfort in the mouth, an embodiment may be adopted in which an acetate filter is disposed on the upstream side and a hollow segment such as a center hole is disposed on the downstream side. Note that, instead of the acetate filter, a paper filter filled with sheet-like pulp paper may be used.
In addition, in manufacturing the filter, adjustment of ventilation resistance and addition of additives (known adsorbents, fragrances, fragrance retention materials, etc.) can be designed as appropriate.

<2. Electrically heated tobacco products>
One embodiment of the electrically heated tobacco product includes an electrically heated device that includes a heater member, a battery unit that serves as a power source for the heater member, and a control unit that controls the heater member; An electrically heated tobacco product comprising a non-combustible heated tobacco as described above, which are inserted into contact with each other.
The electrically heated tobacco product may be of the type shown in FIG. 5 in which the outer peripheral surface of a non-combustible heated cigarette is heated, or the tobacco rod part of a non-combustible heated cigarette as shown in FIG. It may also be an embodiment in which heating is performed from inside. Although the electric heating device 2 shown in FIGS. 5 and 6 is provided with an air introduction hole, it is not shown here. The electrically heated tobacco product will be described below with reference to FIG.
The electrically heated tobacco product 3 is used by being inserted into the heater member 23 disposed inside the electrically heating device 2 so that the non-combustible heated tobacco 1 described above comes into contact therewith.
The electric heating device 2 includes a battery unit 20 and a control unit 21 inside a frame 22 made of resin, for example.
When the non-combustible heated tobacco 1 is inserted into the electric heating device 2, the outer circumferential surface of the tobacco rod comes into contact with the heater member 23 of the electric heating device 2, and eventually the entire outer circumferential surface of the tobacco rod and the wrapping section come into contact with each other. A portion of the outer peripheral surface contacts the heater member.
The heater member 23 of the electric heating device 2 generates heat under the control of the control unit 21 . When the heat is transmitted to the tobacco rod portion of the non-combustible heating type cigarette, the aerosol-generating base material, flavor components, etc. contained in the tobacco filler in the tobacco rod portion are volatilized.

The heater member may be, for example, a sheet heater, a flat heater, or a cylindrical heater. The sheet-shaped heater is a flexible sheet-shaped heater, and includes, for example, a heater containing a film (about 20 to 225 μm thick) of a heat-resistant polymer such as polyimide. The flat heater is a rigid flat heater (about 200 to 500 μm thick), and includes, for example, a heater that has a resistance circuit on a flat base material and uses this portion as a heat generating part. A cylindrical heater is a hollow or solid cylindrical heater (approximately 200 to 500 μm thick), such as a heater that has a resistance circuit on the outer circumferential surface of a cylinder made of metal or the like and uses that part as a heat generating part. . Other examples include rod-shaped heaters and cone-shaped heaters made of metal or the like, which have a resistance circuit inside and use this portion as a heat generating part. The cross-sectional shape of the cylindrical heater may be a circle, an ellipse, a polygon, a polygon with rounded corners, or the like.
In the case of heating the outer circumferential surface of a non-combustion heating type cigarette as shown in FIG. 5, the above-mentioned sheet heater, flat plate heater, or cylindrical heater can be used. On the other hand, in the case of heating from the inside of the tobacco rod portion of a non-combustible heated tobacco as shown in FIG. 6, the above-described flat heater, columnar heater, or conical heater can be used.
The length of the heater member in the longitudinal direction can be within the range of L±5.0 mm, where Lmm is the length of the tobacco rod portion in the longitudinal direction. The length in the long axis direction of the heater member is L mm from the viewpoint of sufficiently transmitting heat to the tobacco rod portion and sufficiently volatilizing the aerosol-generating base material, flavor components, etc. contained in the tobacco filling, that is, from the viewpoint of aerosol delivery. The above is preferable, and from the viewpoint of suppressing the generation of components that have an undesirable effect on the smoking taste, L+0.5 mm or less, L+1.0 mm or less, L+1.5 mm or less, L+2.0 mm or less, L+2.5 mm or less, L+3 It is preferable that they are .0 mm or less, L+3.5 mm or less, L+4.0 mm or less, L+4.5 mm or less, or L+5.0 mm or less.

The heating intensity such as the heating time and heating temperature of the non-combustible heated tobacco by the heater member can be set in advance for each electrically heated tobacco product.
