[0004] Non-combustion heating-type flavor inhalation articles generate aerosols by heating a tobacco rod. During this process, the tipping paper around the tobacco rod is deteriorated by the heat, which can result in the non-combustion heating-type flavor inhalation article being torn or broken, impairing its handleability. In view of these circumstances, an object of the present invention is to provide a non-combustion heating-type flavor inhalation article that is easy to handle after heating.

[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. Non-combustion and heating type flavor inhalation article The non-combustion and heating type flavor inhalation article (hereinafter also simply referred to as "flavor inhalation article") of this embodiment comprises a tobacco rod and a wrapping material joining adjacent members, and a total basis weight in the radial direction on the flavor inhalation article is 40 to 110 g / m ２ The wrapping material has a region X in which the wrapping material exists so that the cross section is such that the cross section is perpendicular to the circumferential surface. The radial direction refers to a direction perpendicular to the circumferential surface. The cross section of the tobacco rod is preferably circular or elliptical, but may also be non-circular, such as a polygon or a rounded polygon. Even when the cross section of the tobacco rod is non-circular, the direction perpendicular to the circumferential surface is conveniently referred to as the radial direction. In this embodiment, the wrapping material includes tipping paper, and the tipping paper is wound so that the CD direction is approximately parallel to the longitudinal direction of the flavor inhalation article. "Approximately parallel" means that the angle between the two directions is parallel or substantially parallel. For example, the angle may be 0 to 10°, or may be 0 to 5°. Generally, tipping paper does not have high strength in the CD direction, which reduces the strength of the joint between the tobacco rod and adjacent members. However, in this embodiment, the provision of region X can impart sufficient strength to the joint.

[0010] There are no particular restrictions on the method for forming region X. For example, region X can be formed by overlapping and winding a single wrapping material in a direction perpendicular to the circumferential surface (first embodiment). Alternatively, the basis weight of part or all of the wrapping material can be set to 40 to 110 g / m. ２ The region X can be formed as follows (second embodiment).

[0011] The location of region X in the longitudinal direction of the flavor inhalation article is not limited. For example, region X may exist over the entire longitudinal direction. Alternatively, region X may be formed in a portion of the longitudinal direction so as to straddle the joint. In this case, region X is preferably wound over 25% or more of the area from the joint toward the other end of the tobacco rod, and more preferably over the entire area of ​​the tobacco rod. Similarly, region X is preferably wound over 25% or more of the area from the joint toward the other end of the adjacent member, and more preferably over the entire area of ​​the adjacent member. Typically, the tobacco rod is disposed on the most upstream side, but the location may be arbitrary. "Downstream" refers to the direction toward the mouth end, and "upstream" refers to the opposite direction.

[0012] (1) First Aspect [Region X] The first aspect will be described with reference to FIG. 4. In the figure, 10 denotes a non-combustion flavor inhalation article, 8 denotes a wrapping material, 1 denotes a tobacco rod, 3 denotes an adjacent member, and X denotes Region X. In this aspect, one wrapping material 8 is wrapped so as to overlap in a direction perpendicular to the circumferential surface, forming Region X. Region X occupies 20 to 100% of the circumferential area of ​​the flavor inhalation article. The percentage of the area occupied by a certain region in the circumferential direction is hereinafter also referred to as the "occupancy rate." If the occupancy rate of Region X is below the lower limit, the strength of the flavor inhalation article will be insufficient. From this perspective, the lower limit of the occupancy rate of Region X is preferably 50% or more. If the occupancy rate of Region X is not 100%, the total basis weight in the radial direction of the region other than Region X (referred to as Region Y for convenience) is not limited. However, if the total basis weight in the radial direction of Region Y is too high, manufacturing will be difficult and thermal conductivity may be reduced when the tobacco rod is heated from the outside. From this viewpoint, in one embodiment, the total basis weight in the radial direction of the region Y is 40 g / m ２ However, the total basis weight in the radial direction of the region Y is less than 110 g / m within a range that does not cause the above-mentioned problems. ２ The total basis weight in the radial direction of region Y may be greater than 110 g / m ２ When the area ratio exceeds 10%, the area ratio of the region Y is preferably 1 to 20%, and the upper limit is more preferably 10% or less.

[0013] FIG. 4 shows an embodiment in which region X occupies about 1 / 4 of the circumferential area in the circumferential direction, i.e., the occupancy rate of region X is 25%. In the first embodiment, the wrapping material 8 can be formed only from tipping paper. The basis weight of the tipping paper itself is adjusted to achieve the basis weight of region X. For example, if the basis weight is x (g / m ２ When n layers of tip paper (g / m) are wound to form region X, the basis weight of region X is n x (g / m) ２ ) is defined as follows. Therefore, x and n are selected so that n x is the desired value. However, n here is an integer, and when the number of turns is expressed as a decimal such as 1.5, it is an integer rounded up to the nearest whole number. Figure 4 shows an embodiment in which the tipping paper is double-wrapped. In this case, for example, 20 to 55 g / m ２ Tipping papers having a basis weight of 100g or less can be used.

[0014] The circumferential length of the tipping paper is selected so as to achieve the occupancy rate of the region X. For example, the circumferential length of the tipping paper is preferably 1.2 to 2.8 times the circumference of the flavor inhalation article, and the upper limit is more preferably 2.2 times or less. When the circumferential length is 1.2 times, the region X formed by doubly wrapping the tipping paper covers an area of ​​approximately 20% of the entire circumference of the non-combustion heating type flavor inhalation article. In this case, the occupancy rate is 20%. This mode is also sometimes referred to as 1.2-fold wrapping. When the circumferential length is 2.2 times, the doubly wrapped region of the tipping paper covers an area of ​​80% of the entire circumference of the non-combustion heating type flavor inhalation article, and the remaining 20% ​​of the entire circumference becomes a triple-wrapped region. The triple-wrapped region can be used as a gluing margin. The double-wrapped region and the triple-wrapped region have a thickness of 40 to 110 g / m ２ When the sheet has a basis weight of 100%, the occupancy rate of the area X is 100%.

[0015] The total basis weight in the radial direction of the wrapping material in region X (hereinafter simply referred to as "basis weight in region X") is 40 to 110 g / m ２ However, if the basis weight is below the lower limit, the strength of the flavor inhalation article is insufficient, whereas if the basis weight is above the upper limit, manufacturing becomes difficult and, furthermore, thermal conductivity decreases when the flavor inhalation article is heated from the outside.

[0016] [Tipping Paper] Tipping paper is paper that is used to wrap and bond multiple components. In this case, the CD direction of the tipping paper is approximately parallel to the longitudinal direction of the non-combustion heating flavor inhalation article. The CD direction of the tipping paper is a direction perpendicular to the direction in which the paper material is transported (MD direction) in the papermaking process. The tipping paper is preferably fixed with an adhesive, and it is preferable that adhesive be applied to at least the terminal end in the circumferential direction of the tipping paper (see Figure 5). In this case, it is preferable that adhesive be applied to the terminal end in a direction perpendicular to the circumferential direction (the longitudinal direction of the non-combustion heating flavor inhalation article).

[0017] As the tipping paper, paper normally used in the field can be used. The tipping paper may be uncoated paper or coated paper. The coated paper may be clear coated paper having a coating layer containing no pigment on a base paper, or pigment coated paper having a pigment coating layer on a base paper. From the viewpoint of forming the region X without impairing the workability during winding, the basis weight of the tipping paper in this embodiment is preferably 55 g / m ２ or less, more preferably 53 g / m ２ The lower limit of the basis weight is preferably 20 g / m ２ More preferably, 30 g / m ２ That's all.

[0018] As mentioned above, the strength of tipping paper in the CD direction is generally lower than the strength in the MD direction, but a non-combustion heating-type flavor inhalation article that is easy to handle after heating can be provided by providing region X. The tensile strength of the tipping paper in the CD direction is preferably 12 N / 15 mm or more, more preferably 13 N / 15 mm or more.

[0019] (2) Second Embodiment A second embodiment will be described with reference to Fig. 6. The reference numerals in the figure are the same as those in Fig. 4. In this embodiment, a single wrapping material 8 wraps the tobacco rod and the adjacent member. The method for forming the region X in the second embodiment is not limited, but examples thereof include the following.

[0020] 1) 40-110g / m ２The tipping paper described in the first embodiment can be used, but the basis weight is 40 to 110 g / m. ２ The tip paper may be uncoated paper, clear coated paper, or pigment coated paper having a pigment coating layer on a base paper. In this case, the occupancy rate of region X is 100%.

[0021] 2) Wrapping the tip paper in a single layer with a wrapping material comprising a reinforcing sheet placed on the tip paper. In this embodiment, the thickness is, for example, 30 g / m ２ 50 / m ２ This can be achieved by wrapping a wrapping material to which a reinforcing sheet having a basis weight of 100g is attached in a single layer. In this case, the occupancy rate of region X is adjusted by the circumferential length of the reinforcing sheet. The material of the reinforcing sheet is not limited, but from the viewpoint of handleability, it is preferably paper or a polymer sheet. The reinforcing sheet is preferably disposed on the inside of the circumferential surface. Figure 7 shows an embodiment in which region X is formed by disposing a reinforcing material 9 on the inner circumferential surface of tipping paper 7. In this figure, the occupancy rate of region X is 25%.

[0022] (3) Tobacco Rod Each component will be described below with reference to FIG. 1. FIG. 1 shows one embodiment of a non-combustion, direct-heating flavor inhalation article. In the figure, 10 denotes a non-combustion flavor inhalation article, 1 denotes a tobacco rod, W denotes a wrapper, 3 denotes an adjacent component (preferably a cooling component) adjacent to the tobacco rod, 5 denotes a mouthpiece, 52 denotes a filter, 54 denotes a center-hole filter, 7 denotes tipping paper, 8 denotes a wrapping material, and V denotes ventilation. The embodiment shown in FIG. 1 heats the tobacco material, and is therefore also referred to as a non-combustion, direct-heating flavor inhalation article. FIG. 1 (1) shows an embodiment in which the wrapper W is a wrapping paper for the tobacco rod 1, which is then wrapped with a wrapping material 8. The CD direction of the tipping paper included in the wrapping material 8 is approximately parallel to the longitudinal direction of the non-combustion, direct-heating flavor inhalation article. FIG. 1 (2) shows an embodiment in which the wrapper W is a wrapping material 8 that wraps the tobacco rod 1 and the adjacent component 3. In this embodiment, the CD direction of the tipping paper included in the wrapping material 8 is approximately parallel to the longitudinal direction of the non-combustion direct heating flavor inhalation article. The CD direction orientation of the tipping paper 7 not included in the wrapping material 8 is not limited.

[0023] A tobacco rod is a generally cylindrical member for generating flavor and aroma components contained in tobacco material. A tobacco rod comprises tobacco material and a cigarette paper (wrapper) surrounding the tobacco material. The shape of the tobacco material packed into the cigarette paper is not limited, and examples include a sheet, a sheet cut into widths of 0.8 to 1.2 mm, or a piece cut into widths of 0.8 to 1.2 mm. The sheet may be gathered, folded, or spirally packed into cigarette paper without being cut, to form a tobacco rod. Alternatively, the sheet may be cut into strips and packed into cigarette paper concentrically or with the longitudinal direction of the strips parallel to the longitudinal direction of the tobacco rod to form a tobacco rod.

[0024] The packing density of the tobacco material is not particularly limited, but from the viewpoint of ensuring the characteristics of the non-combustion flavor inhalation article and imparting a good smoking taste, it is usually 250 mg / cm ３ or more, preferably 320 mg / cm ３ The upper limit is usually 800 mg / cm ３ or less, preferably 600 mg / cm ３ The length of the tobacco rod 1 is not limited, but is preferably 15 to 25 mm. The diameter is also not limited, but is preferably 6 to 8 mm.

[0025] The tobacco material may generate steam when heated. The heating temperature is not limited, but is preferably about 250 to 350°C. To promote the generation of aerosol, an aerosol source such as glycerin, propylene glycol, or a polyol such as 1,3-butanediol may be added to the tobacco material. The amount of the aerosol source added is preferably 5 to 50% by weight, more preferably 10 to 30% by weight, based on the dry weight of the tobacco material. In addition, known flavorings and the like may be added to the tobacco material.

[0026] (3) Adjacent Member The adjacent member 3 is a member adjacent to the downstream side of the tobacco rod 1. "Downstream" refers to the direction toward the mouth end. Examples of the adjacent member include a cooling member for cooling the aerosol, a support member for increasing the strength of the entire product, or a mouthpiece, which will be described later. The adjacent member 3 is preferably a cooling member.

[0027] The cooling member is a member for promoting aerosolization by cooling flavor and aroma components and vapor generated in the tobacco rod 1. The cooling member may be a hollow paper tube. The paper tube is preferably made of cardboard, which has higher rigidity than cigarette paper or tipping paper. The paper tube may be provided with ventilation V (openings). A plurality of ventilations are preferably provided along the circumference of the paper tube. The cooling member may also be filled with a gathered sheet to improve heat exchange efficiency. The dimensions of the cooling member are not limited, but the length is preferably 15 to 25 mm, and the diameter is preferably 5.5 to 7.5 mm.

[0028] (4) Mouthpiece The mouthpiece is a component that constitutes the mouth end. In one embodiment, the mouthpiece 5 includes a filter 52 and a center hole filter 54. Known filters can be used as the filter 52 and the center hole filter 54.

[0029] (5) Manufacturing Method of Non-Combustion Heating Type Flavor Inhalation Article The non-combustion heat-type flavor inhalation article can be manufactured by any method as long as the effect is not impaired. For example, the non-combustion heat-type flavor inhalation article can be manufactured by a method including a step of preparing the above-mentioned components and wrapping them with the above-mentioned tipping paper.

[0030] 2. Non-combustion heating type flavor inhalation system The combination of a non-combustion heating type flavor inhalation article and a heating device is also called a non-combustion heating type flavor inhalation system. Figure 2 shows one embodiment of this system. In the figure, 100 is a non-combustion heating type flavor inhalation system, 10 is a non-combustion type flavor inhalation implement, and 30 is a heating device equipped with a heater. The heating device is equipped with a heater, a housing, a power source, etc.

[0031] The heating device 30 includes a body H1, a heater H2, a metal tube H3, a battery unit H4, and a control unit H5. The body H1 has a cylindrical recess H6, and the heater H2 and metal tube H3 are disposed in positions corresponding to the tobacco rod 1 inserted therein. The heater H3 may be an electric resistance heater, and power is supplied from the battery unit H4 in response to instructions from the temperature-controlling control unit H5, causing the heater H2 to heat. The heat generated by the heater H2 is transferred to the tobacco rod 1 through the metal tube H3, which has high thermal conductivity. While the figure shows a heating device 10 that heats the tobacco rod 1 from the outside, it may also heat from the inside. The heating temperature of the heating device 10 is not particularly limited, but is preferably 400°C or less, more preferably 150 to 400°C, and even more preferably 200 to 350°C. The heating temperature refers to the temperature of the heater in the heating device 10.

[0032] In the non-combustion heating-type flavor inhalation article, the portion inserted into the heating device 10 preferably includes a part or all of the tobacco rod 1, or the joint between the tobacco rod 1 and the adjacent member 3. In this case, the non-combustion heating-type flavor inhalation article preferably includes the wrapping material according to this embodiment in the portion inserted into the heating device 10.

[0033] [Example 1] A paper tube having a circumference of 22.3 mm and a length of 20 mm and another paper tube having a circumference of 22.3 mm and a length of 40 mm were prepared, and the two were arranged so that their end faces abutted against each other. Tipping paper A (basis weight 37 g / m ２ ) was prepared. Tipping paper A was cut into a length of 45 mm and a width of 33.5 mm, and the paper tube was wound 1.5 times so that the length direction of the tipping paper was parallel to the longitudinal direction of the paper tube, to prepare a test specimen (see Figure 4). At this time, the CD direction of the tipping paper was approximately parallel to the longitudinal direction of the test specimen. The basis weight of region X was 74 g / m ２ , the occupancy rate of region X was 50%.

[0034] A 20 mm paper tube serving as a test specimen was inserted into a heating device. The temperature of the heating device was set to 295°C, and the test specimen was subjected to a smoking test using a smoking machine. Specifically, using an automatic smoking machine (LM-1 manufactured by Borgwaldt KC Inc.), the sample was automatically smoked under the conditions of a smoke volume of 55.0 ml / sec, a smoke time of 2 sec / puff, and 9 puffs. During this process, the joint was heated. After smoking, the sample was cooled to room temperature and subjected to a breaking test. An overview of the test is shown in Figure 3. In the figure, P is the plunger, B is the base, and J is the joint. The load at break and other data are shown in Table 1.

[0035] [Example 2] A test piece was prepared and evaluated in the same manner as in Example 1, except that tipping paper A having a length of 45 mm and a width of 50 mm was prepared and the paper tube was wound 2.2 times. In this example, the area where tipping paper A was wound twice occupied 80% of the area, and the area where tipping paper A was wound three times occupied 20% of the area. The basis weight of the area where tipping paper A was wound three times was 111 g / m ２ Therefore, it does not fall under region X. Therefore, the basis weight of region X in this example is 74 g / m ２ The occupancy rate of region X was 80%.

[0036] [Example 3] Tipping paper B (basis weight 48 g / m ２ ) was prepared and cut into a size of 45 mm in length and 22.3 mm in width. Test pieces were prepared and evaluated in the same manner as in Example 1, except that the tipping paper was wound 1.1 times around the paper tube. In this example, the area where tipping paper B was wound once occupied 90% of the area, and the area where tipping paper B was wound twice occupied 10% of the area. The basis weight of the former area was 48 g / m ２ , the basis weight of the latter region is 96 g / m ２ Therefore, both of these correspond to region X. Therefore, the basis weight of region X in this example is 74 g / m ２ , 96 g / m ２ The occupancy rate of region X was 100%. [Comparative Example 1] A test piece was prepared and evaluated in the same manner as in Example 1, except that tipping paper A having a length of 45 mm was prepared and the paper tube was wound 1.1 times. The basis weight of region X was 74 g / m ２ , the occupancy rate of region X was 10%.

[0037]

[0038] It is clear that the test pieces of the Examples require a greater force to break than the test pieces of the Comparative Examples. The "average load" is the maximum load applied until the sample breaks, with a smaller number indicating faster breakage and a larger number indicating less breakage. Comparing the Examples and Comparative Examples, the Examples show higher values ​​for both average load and breakage. This clearly shows that the test pieces of the Examples exhibit a sufficient effect of suppressing breakage.
