[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.

[0005] Conventionally, tipping paper in flavor inhalation articles has been used with its CD direction parallel to the longitudinal direction of the flavor inhalation article. However, the inventors have found that the above-mentioned problem can be solved by changing the orientation of the tipping paper. That is, the above-mentioned problem is solved by the following present invention. Aspect 1: A non-combustion and heating type flavor inhalation article comprising tipping paper joining a tobacco rod and an adjacent member adjacent thereto, wherein the MD direction of the tipping paper is approximately parallel to the longitudinal direction of the non-combustion and heating type flavor inhalation article. Aspect 2: The non-combustion and heating type flavor inhalation article according to Aspect 1, wherein the tipping paper has a pulp content of 50 to 100 wt %. Aspect 3: A non-combustion and heating type flavor inhalation article according to Aspect 1, wherein the tipping paper has a pulp content of 55 g / m ２A non-combustion and heating type flavor inhalation article according to aspect 1 or 2, having a basis weight of: A non-combustion and heating type flavor inhalation article according to aspect 4, wherein the tip paper has a tensile strength of 15 N / 15 mm or more in the MD direction.

[0006] The present invention provides 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 Heating Flavor Inhalation Article The non-combustion heat-type flavor inhalation article (hereinafter also simply referred to as "flavor inhalation article") of this embodiment includes tipping paper that joins a tobacco rod and an adjacent member adjacent thereto, and the MD direction of the tipping paper is approximately parallel to the longitudinal direction of the non-combustion heat-type 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°. Until now, tipping paper has been wound so that its CD direction is parallel to the longitudinal direction of the non-combustion heat-type flavor inhalation article. However, in this embodiment, since the MD direction of the tipping paper is parallel to the longitudinal direction of the non-combustion heat-type flavor inhalation article, sufficient strength can be imparted to the flavor inhalation article.

[0010] (1) Tipping Paper Tipping paper is paper that is wound around and joined to multiple components. In this embodiment, the MD direction of the tipping paper is approximately parallel to the longitudinal direction of the non-combustion heating type flavor suction article. The MD direction of the tipping paper is the 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. 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 suction article).

[0011] As the tipping paper, paper normally used in this field can be used. From the viewpoint of achieving excellent strength, the pulp content of the tipping paper is preferably 50 to 100% by weight, more preferably 60 to 98% by weight. When the pulp content is 100% by weight, the tipping paper is uncoated paper. When the pulp content is less than 100% by weight, the tipping paper may be coated paper. The coated paper may be clear coated paper having a coating layer that does not contain pigment on base paper, or pigment coated paper having a pigment coating layer on base paper.

[0012] In this embodiment, the basis weight of the tip paper 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.

[0013] The tensile strength of the tip paper in the MD direction is preferably 15 N / 15 mm or more, more preferably 20 N / 15 mm or more.

[0014] (2) Tobacco Rod Each component will be described below with reference to FIGS. 1 and 4. FIG. 1 shows one embodiment of a non-combustion, burning flavor inhalation article, and FIG. 4 shows one embodiment of a wrapping. In the figures, 10 denotes a non-combustion, burning flavor inhalation article, 1 denotes a tobacco rod, W denotes a wrapper, 3 denotes an adjacent member (preferably a cooling member) adjacent to the tobacco rod, 5 denotes a mouthpiece, 52 denotes a filter, 54 denotes a center hole filter, 7 denotes tipping paper, 7' denotes a second tipping paper, and V denotes ventilation. The embodiment shown in FIG. 1 is also referred to as a non-combustion, direct heating flavor inhalation article because it heats the tobacco material. FIG. 1(1) shows an embodiment in which the wrapper W is a cigarette paper for the tobacco rod 1, and is wrapped with tipping paper 7 from above. The MD direction of the tipping paper 7 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 tipping paper 7 that wraps the tobacco rod 1 and the adjacent member 3. In this embodiment, the MD direction of the wrapper W, i.e., the tipping paper 7, is approximately parallel to the longitudinal direction of the non-combustion direct heating flavor inhalation article. On the other hand, the orientation of the MD direction of the second tipping paper 7' is not limited.

[0015] 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.

[0016] 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 / cm３ 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.

[0017] 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.

[0018] (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.

[0019] 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.

[0020] (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.

[0021] (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.

[0022] 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.

[0023] 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.

[0024] 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 tipping paper according to this embodiment in the portion inserted into the heating device 10.

[0025] [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) having a length of 45 mm and a width of 25 mm was used. ２ The paper tube was wound around the tip paper to prepare a test piece (see FIG. 3). At this time, the MD direction of the tip paper was approximately parallel to the longitudinal direction of the test piece.

[0026] The 20 mm cardboard tube of the 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 information are shown in Table 1.

[0027] [Comparative Example 1] A test piece was prepared and evaluated in the same manner as in Example 1, except that the direction perpendicular to the MD of the tip paper A, i.e., the CD direction, was approximately parallel to the longitudinal direction of the test piece.

[0028]

[0029] The average load is the maximum load applied until the sample breaks, with a smaller number indicating faster breakage and a larger number indicating resistance to breakage. The average distance is the average distance the plunger travels until the sample breaks, and is an index of the tenacity of the sample, i.e., the sample bends and does not break easily. Comparing the Examples and Comparative Examples, the Examples show higher values ​​for both the average distance and the average load. This clearly shows that the test pieces of the Examples exhibit a sufficient effect of suppressing breakage.
