"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 and heating type flavor inhalation article. However, in this embodiment, the MD direction of the tipping paper is parallel to the longitudinal direction of the non-combustion and heating type flavor inhalation article, which provides sufficient strength to the flavor inhalation article.
[0010] (1) Tipping paper Tipping paper is paper that wraps and joins 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 circumferential end 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 pigment-free coating layer 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 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.

In the figure, 10 is a non-combustion flavor inhalation article, 1 is a tobacco rod, W is a wrapper, 3 is an adjacent member (preferably a cooling member) adjacent to the tobacco rod, 5 is a mouthpiece, 52 is a filter, 54 is a center hole filter, 7 is tipping paper, 7' is a second tipping paper, and V is ventilation. The embodiment shown in FIG. 1 is also called 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 wrapping 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 MD direction of second tipping paper 7' is not limited.
[0015] 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.
[0016] 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 3The 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 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.
[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 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.
[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. As the filter 52 and the center hole filter 54, known filters can be used.
[0021] (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.
[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 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.
[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 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 power is supplied from a battery unit H4 in response to instructions from a control unit H5 that controls temperature, causing the heater H2 to heat. The heat generated by the heater H2 is transferred to the tobacco rod 1 through a metal tube H3 with high thermal conductivity. While the figure shows a mode in which the heating device 10 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 of 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. [Example]
[0025] [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. Tip paper A (basis weight 37 g / m) with a length of 45 mm and a width of 25 mm was used. 2 ) was prepared, and the paper tube was wound around it to prepare a test piece (see FIG. 3). At this time, the MD direction of the tip paper was made approximately parallel to the longitudinal direction of the test piece.
[0026] The 20 mm paper 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 puff volume of 55.0 ml / sec, a puff time of 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 data 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 tip paper A, i.e., the CD direction, was approximately parallel to the longitudinal direction of the test piece.
[0028] [Table 1]
[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. [Explanation of symbols]
