[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 heating type flavor inhalation product The non-combustion heating type flavor inhalation article (hereinafter also simply referred to as "flavor inhalation article") of this embodiment includes a tobacco rod and a wrapping material that joins adjacent members to the tobacco rod, and the flavor inhalation article has a total basis weight in the radial direction of 40 to 110 g / m 2The wrapping material has a region X where the wrapping material is present so that the cross section is such that the cross section is 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, the strength of tipping paper in the CD direction is not high, 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 the region X. For example, the 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 [Area X] A first embodiment 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 embodiment, 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 proportion of the area occupied by a region in the circumferential direction is hereinafter also referred to as "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, it will be difficult to manufacture and the thermal conductivity may decrease when the tobacco rod is heated from the outside. From this perspective, in one embodiment, the total basis weight in the radial direction of 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 the region Y may be greater than 110 g / m 2 If it exceeds this limit, the occupancy rate of 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 ) is wound n times to form area X, the basis weight of area 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 the integer obtained by rounding up the decimal point. 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 its 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 weight of the double-wrapped region and the triple-wrapped region is 40 to 110 g / m 2 If the sheet has a basis weight of 100%, the occupancy rate of region 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] [Tip paper] Tipping paper is a paper that wraps and joins multiple components. In this case, the CD direction of the tipping paper is approximately parallel to the longitudinal direction of the non-combustion heating type flavor inhalation article. The CD direction of the tipping paper is a direction perpendicular to the direction (MD direction) in which the paper material is transported 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 end in the circumferential direction of the tipping paper (see Figure 5). In this case, it is preferable that adhesive be applied to the end in a direction perpendicular to the circumferential direction (the longitudinal direction of the non-combustion heating type 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 the base paper, or pigment coated paper having a pigment coating layer on the base paper. From the viewpoint of forming the region X without impairing the workability during wrapping, the basis weight of the tipping paper in this embodiment is preferably 55 g / m 2 Less than 53 g / m, more preferably 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 that in the MD direction, but the provision of region X makes it possible to provide a non-combustion heating-type flavor inhalation article that is easy to handle after heating. 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 aspect 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 tobacco rod and an adjacent member are wrapped around one wrapping material 8. The method for forming region X in the second embodiment is not limited, but examples thereof include the following.

[0020] 1) 40-110g / m 2 Wrap one layer of tipping paper having a basis weight of The tip 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 the base paper. In this case, the occupancy of region X is 100%.

[0021] 2) Wrapping the product once with a wrapping material comprising tipping paper and a reinforcing sheet placed on top of the tipping paper In this embodiment, for example, 30 g / m 250 for part or all of the tipping paper having a basis weight of g / m 2 This can be achieved by wrapping a wrapping material to which a reinforcing sheet having a basis weight of 1000g 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 ease of handling, 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 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 Figure 1. Figure 1 shows one embodiment of a non-combustion type roasted flavor inhalation article. In the figure, 10 is a non-combustion type flavor inhalation article, 1 is a tobacco rod, W is a wrapper, 3 is an adjacent component (preferably a cooling component) adjacent to the tobacco rod, 5 is a mouthpiece, 52 is a filter, 54 is a center hole filter, 7 is tipping paper, 8 is a wrapping material, and V is ventilation. The embodiment shown in Figure 1 is also called a non-combustion direct heating type flavor inhalation article because the tobacco material is heated. 1 FIG. 1(1) shows an embodiment in which the wrapper W is a wrapping paper for a tobacco rod 1, and 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 type 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 member 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 type flavor inhalation article. The CD direction of the tipping paper 7 that is not included in the wrapping material 8 is not limited.

[0023] A tobacco rod is a roughly cylindrical component for releasing 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 filled into the cigarette paper is not limited, and examples include a sheet, the sheet cut into widths of 0.8 to 1.2 mm, or shreds cut into widths of 0.8 to 1.2 mm. The sheet may be gathered, folded, or spirally wound without being cut, and then filled into cigarette paper to form a tobacco rod. Alternatively, the sheet may be cut into strips and filled 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 is generally 250 mg / cm from the viewpoint of ensuring the characteristics of the non-combustion flavor inhalation article and imparting a good smoking taste. 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 parts 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 is more rigid than cigarette paper or tipping paper. The paper tube may be provided with ventilation V (openings). It is preferable that multiple ventilations are 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. As the filter 52 and the center hole filter 54, known filters can be used.

[0029] (5) Method for manufacturing non-combustion heating type flavor inhalation article The non-combustion and heating type flavor inhalation article can be manufactured by any method as long as the effect is not impaired. For example, the non-combustion and heating 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 referred to as a non-combustion heating type flavor inhalation system. One embodiment of this system is shown in Figure 2. 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 the metal tube H3 are disposed at positions corresponding to the tobacco rod 1 to be inserted therein. 2 The heater H2 can be a heater using electrical resistance, and is heated by power supplied from the battery unit H4 in response to an instruction from the control unit H5 that controls the temperature. The heat generated by the heater H2 is transferred to the tobacco rod 1 through a metal tube H3 with high thermal conductivity. 30 Although the embodiment in which the tobacco rod 1 is heated from the outside has been shown, it may also be heated from the inside. 30 The heating temperature by the heating device 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. 30 Indicates the heater temperature.

[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. [Example]

[0033] [Example 1] A paper tube with a circumference of 22.3 mm and a length of 20 mm and another paper tube with 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, the sample was automatically smoked using an automatic smoking machine (LM-1 manufactured by Borgwaldt KC Inc.) under the following conditions: smoke volume 55.0 ml / sec, smoking time 2 sec / puff, and 9 puffs. The joint was heated during the smoking process. 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 information 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 area X. Therefore, the basis weight of area X in this example is 74 g / m 2 , the occupancy rate of area X was 80%.

[0036] [Example 3] Chip 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 / m2 , the basis weight of the latter region is 96 g / m 2 Therefore, both of these fall into region X. Therefore, the basis weight of region X in this example is 74 g / m 2 , 96g / m 2 and 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 tip 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] [Table 1]

[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. [Explanation of symbols]
