Description of the invention: [Technical field to which the invention belongs] The present invention relates to a kind of fire which is difficult to prevent from fire caused by cigarettes ordered by smokers due to carelessness, etc. Every item around the mains <10,000-type low-burning cigarette. [Previous technology] When the cigarette was dropped by the smoker's carelessness on the bed, etc., a proposal was placed on the tobacco roll to prevent the flame from burning to the bed. A wide 2 to 2 band of cellulose paper is used to give self-extinguishing cigarettes (Examined Japanese Patent Laid-Open No. 63-85200), and a tobacco roll is coated with a flame-resistant substance Striped cigarettes (refer to Japanese Patent Application Laid-Open No. 7_300795), etc. In addition, a non-combustible material = cigarette roll paper is known. The knowledge of these technologies is based on the height of tobacco roll paper. In the flammability and low-flammability areas, although smoking is still possible in the high-flammability area, the cigarette will extinguish in the middle of the low-flammability area. In addition, it is known in the past to reduce the sidestream smoke per hour. Quantity for purpose By reducing the burning speed of cigarettes, it is possible to provide cigarettes that can be easily extinguished midway. As such cigarettes, it has been proposed to use a cigarette roll paper with a small amount of filler as the inner roll paper, and a normal cigarette roll paper as the outer roll paper, and Cigarettes using these rolls of paper for wrapping shredded tobacco (refer to Japanese Patent No. 2572488). As low-smoker cigarettes, it has been proposed that a rod of smoking material (r0d) with a filling density of 1 to 260 mg / cm3 be used. Cigarettes wrapped in roll paper with a coresta unit of 7 or less air permeability (refer to Japanese Patent No. 3001582). Furthermore, there have been proposals: 315737 5 1243652 using a low air permeability (Koler Star unit is 7) cigarettes with low filler and low weight per unit area to reduce the burning rate of cigarettes (refer to International Patent Publication No. WO 01/48316). However, when using roll papers with non-combustible fields, It has a non-combustible part and a flammable part, so it becomes non-uniform combustion during smoking, and the smoking taste is also unstable. Furthermore, the burning speed is reduced to achieve low burning properties. The method is to reduce the air permeability of the roll paper to achieve its purpose. The air permeability effect through the roll paper is reduced, so that the amount of carbon monoxide (co) in the mainstream smoke is increased, and the carbon monoxide / tar (tar) is increased. Ratio (c / τ). Furthermore, the decrease in the breathability of the rolled paper will cause a change in the smoking taste of cigarettes, so that for ordinary smokers, there is a problem of inconsistency. On the other hand, the use of fillers Although it is known that the burning rate of cigarettes with a low proportion of paper rolls will decrease, and it is generally known from experience that the cigarettes will naturally extinguish halfway, so that the amount of filler cannot be reduced too much. Therefore, the object of the present invention is to provide a cigarette that can be made and used in general. The same smoking action, the burning speed is about the same as the burning speed of ordinary cigarettes, and while improving the C / τ (carbon monoxide / tar) ratio in mainstream smoke, it can still show low-burning cigarettes. [Summary of the Invention] In the research on low-flame cigarettes, the present inventors have found that in cigarettes composed of tobacco fillers and cigarette papers, it is not necessary to use special bands or flame-resistant substances, but only to roll the cigarettes. The specific air permeability of the cigarette paper with a tobacco filling material rod and the amount of filler blended in the paper are set to a specific value, so that the above-mentioned purpose of tobacco can be achieved 6 315737 1243652. By setting the inherent air permeability of the cigarette paper to a predetermined range: within ', the filler can be reduced as much as possible while maintaining natural combustion. The present invention has been developed based on such findings. That is, according to the present invention, a cigarette is provided, which is provided with a tobacco filling material rod, and a cigarette roll paper wrapped with the rod, and containing pulp and filler, and is characterized in that the roll paper has a Corusda unit It is more than 20, the inherent air permeability below the ribs, and containing the aforementioned filler 0 in the ratio of ^ to 5.Gg/m2. The cigarette of the present invention is continuously burned naturally and allowed to burn naturally for a certain distance. When it is on a substrate, it can show a low ductility that has a median value of the distance that the carbonization line of the cigarette paper rolls along the cigarette axis direction before the cigarette stops burning. In a preferred aspect of the present invention, a cigarette can be provided, which is provided with a tobacco filling material rod and a cigarette roll paper rolled with the rod, and is characterized in that the roll paper has a Corusta unit of 20 or more Inherent air permeability below 80, containing 1.4 to 3.7 g / m2 proportion of filler, and containing a flame modifier of 6% by weight, and the aforementioned cigarette filling material is filled with a filling density of 13 to 230 mg / cm3 filling. [Embodiment] Hereinafter, the present invention will be described in more detail. The cigarette of the present invention is provided with a tobacco filler rod and a cigarette paper rolled with the tobacco filler rod. The cigarette of the present invention has the same appearance and shape as the cigarette. The tobacco filling material rod used in the cigarette of the present invention is composed of general cut tobacco 315737 7 1243652 and the like. Tobacco can contain puffed tobacco or reconstituted tobacco, as well as middle bone. The filling density of the tobacco filling material rod is preferably 130 to 260 mg / cm3. = Jumping out of the filling density range, even if the cigarette roll paper roll of the present invention is coated, the flame retardancy cannot be sufficiently reduced. The filling density of the tobacco filling material is preferably 130 to 230 mgW, and more preferably 140 to 230 mg / cm3.

The inherent permeability of cigarette paper is preferably 'Collesida' unit is 20 or more 'and '80 or less, more preferably the Corusda unit = outside. For cigarette paper, mechanical or electrical tooth holes can be used in accordance with general methods. . There is no particular limitation on the air permeability of the roll paper having such an opening. The cigarette paper of the present invention contains a filler. As for the filler, it can be used as usual: rhenium carbonate, potassium carbonate #carbonate; hydroxide word, magnesium hydroxide special hydroxide. The amount of filler in the cigarette paper is 10 to 5.0 g / m2. If the filler amount is less than 10 g / m2, the cigarette will be annihilated halfway during natural combustion. * When the filler amount is 5.0 coffee, ±, it is expected to achieve a low 315737 8 1243652 scorchability. The amount of the filler is preferably from L4 to 3.7 g / m2, more preferably from 1.6 to 3 g / m2. In addition, the proportion of the filler in the cigarette paper is preferably 6 to 30% by weight, more preferably 7 to 21% by weight, and particularly preferably 8 to 17% by weight. The weight per unit area of cigarette paper is preferably 17 to 28 g / m2. If the unit amount per unit area is 17 g / m2 or less, it is difficult to produce a stable roll paper, and if it exceeds 28 g / m2, the 'flameability' tends to increase. The unit area weight of the roll paper is more preferably 18 to 25 g / m2, and particularly preferably 18i22 g / m2. Tobacco paper can also be added with a citric acid or a salt thereof (sodium salt, potassium salt) and the like, but the content thereof is preferably 0 to 10% by weight. : When the amount of the burning modifier is more than 1.0% by weight, the C / T ratio tends to increase.

Μ In addition, if the cigarette roll paper of the present invention has a tensile strength of 10 to 20 N / 15 mm or more, it can be smoothly used even in a high-speed cigarette manufacturing machine for manufacturing cigarettes at a speed of 8000 to 12,000 sticks / minute Make cigarettes. Tensile strength can be adjusted by adjusting the beating degree or pulp amount of the pulp used in cigarette paper. The higher the pulp beating degree and the more pulp per unit area of roll paper, the higher the tensile strength. 7 In the middle of this month, if the inherent permeability of cigarette paper and the ratio of filler in the cigarette paper are set within the above range, although the inherent permeability of cigarette paper is high, it can still be made with low flame retardancy. , Will produce a cigarette with a small c / τ ratio. In addition, the cigarette of the present invention can exhibit a burning speed almost the same as that of ordinary cigarettes. The low-flammability of the cigarette of the present invention is that when the cigarette is allowed to burn naturally for a certain distance, it is placed on a base material (10 sheets of filter paper) and is placed on the substrate (measured in accordance with 315737 9 1243652 ASTM E2187_02b method). The median value of the distance that the carbonization line moves along the cigarette axis direction is 8 mm or less, preferably 4 mm or less. Furthermore, in a plurality of cigarettes of the present invention, the highest value of the frequency of the moving distance may be 8 mm or less, and more preferably 4 mm or less. Hereinafter, the content of the present invention will be described by examples, but the present invention is not limited by these examples. (Examples and Comparative Examples) Tobacco rolls were manufactured by using flax pulp cigarette paper of the specifications not shown in Table 1 so that the tobacco filling density shown in Table φ 1 could be obtained. -, Use anti-H-bow stone, combustion regulators use drop-like sodium. Tobacco is yellow tobacco or blended tobacco. The natural air permeability and tensile strength of the cigarette paper are shown in Table 1. Here, the tensile strength shown in Table 丨 is measured using a tensile strength testing machine STROGRAPHE_s manufactured by Toyo Seiki Co., Ltd. and measured according to the method shown in Japanese Industrial Standard (JIS) P 8113-1998 (size of test piece ·· 15.0mm x about 250mm, the interval between the clips: 180 ± 2mm, tension speed (50mm / min). It is called to measure the natural burning rate of the manufactured cigarettes in accordance with the usual method, and to measure the percent full length burn on 10 sheets of filter paper in accordance with ASTME 2187-02b method. In addition, the median value of the distance that the stone reaction line of the cigarette paper was moved in the direction of the cigarette axis until the ignited cigarette was placed on the filter paper and the cigarette stopped burning (was extinguished halfway) was measured. The results are shown in Table 2. In addition, the mainstream of tobacco 315737 10 1243652, which was generated when each cigarette was burned, was measured by a conventional method to calculate the C / T ratio by calculating the total amount of particulate matter (TPM), carbon monoxide, and tar in the smoke.
