Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to cigarettes with reduced sidestream smoke, especially cigarettes made from inner roll paper and outer roll paper. [Prior art] Various techniques have been proposed to reduce the sidestream smoke of cigarettes. For example, the specification of Japanese Patent No. 2 5 7 24 8 8 discloses that Corest a unit (Corest a is a unit of air permeability of paper) in the unit of air permeability 1 to 5 (Corest a is a unit of air permeability of paper) and contains 1 to 8% by weight filler (such as calcium carbonate ), And cigarettes made from rolled paper with a basis weight of 35 to 65 g / m 2 and containing 18 to 40% by weight filler (such as calcium carbonate). In addition, Japanese Patent Laid-Open No. 6-7142 discloses that an inner roll paper containing a magnesium-containing filler and an outer roll containing an additive combination consisting of an alkali metal ion, an alkaline earth metal ion, an inorganic anion, and an organic anion are disclosed. Cigarettes made of paper. However, it is known that the burning speed of the conventional cigarettes is slow, so although the amount of sidestream smoke per unit time is small, there is a problem that the amount of sidestream smoke per cigarette is large. Therefore, an object of the present invention is to provide a cigarette which has not only a small amount of sidestream smoke per unit time, but also a small amount of sidestream smoke per cigarette. [Summary of the Invention] The present invention is not a technology for attaching a filter or improving tobacco filling materials (tobacco shreds, etc.), but researches the roll paper of rolled cigarettes, and achieves the above-mentioned objective with the results. In other words, according to the present invention, it is possible to provide a roll paper containing calcium carbonate content of less than 4% by weight, and calcium carbonate containing 30 g / m2 or more and a combustion regulator content of 3% by weight or more.

Description of the Invention (2) Cigarettes in the tobacco department of grass-filled rods. [Embodiment] The present invention will be described in detail below. The cigarette of the present invention includes a tobacco section including a tobacco filler rod wrapped with a specific inner roll of paper and a specific outer roll of paper. Ordinary filters can be attached to one end of the tobacco section. In the rolled paper of the rolled tobacco filling rod of the present invention, the content of the calcium carbonate in the inner rolled paper is less than 4% by weight, and it is substantially free of calcium carbonate. If the inner roll of paper contains more than 4% by weight of calcium carbonate, the obtained cigarette will burn too fast and cannot reduce the amount of sidestream smoke per unit time. The inner roll paper is preferably free of calcium carbonate. The pulp constituting the inner roll paper can be used as long as it is flax pulp or the like used for ordinary tobacco products. The pulp amount is preferably 10 to 18 g / m 2. If the amount of pulp is less than 10 g / m 2, it is difficult to stably manufacture rolled paper, and if it exceeds 18 g / m 2, the cigarette tends to smell bad. The lower the air permeability of the inner paper, the lower the sidestream smoke volume of the obtained cigarette per unit time. The air permeability of the inner roll paper is preferably from 1 to 30 Co r e s t a unit (CU), and more preferably from 6CU to 30CU. The inner roll paper may contain a combustion modifier, and its amount is preferably not more than 1% by weight (0 to 1 •% by volume). If the amount of the combustion modifier exceeds 1% by weight, the resulting cigarette tends to fail to maintain the following preferable burning rate: 6 mm / min or more. The combustion regulator added to the inner paper can be selected from sodium citrate, potassium citrate, sodium acetate, potassium acetate, sodium tartrate, potassium tartrate, sodium malate, malate, sodium succinate, potassium succinate, etc. Organic acid test metal salt.

Description of the invention (3) The roll paper used outside the present invention contains more than 30 g / m 2 of calcium carbonate and more than 3% by weight of a combustion regulator. When the amount of carbonate carbonate is less than 30 g / m 2 and / or the ratio of the combustion regulator is less than 3% by weight, the effect of reducing the amount of sidestream smoke cannot be fully exerted. Preferably, the blending amount of carbonic acid is more than 30 g / m2 and less than 50 g / m2. The combustion modifier is blended into the roll paper at a ratio of 3 to 15% by weight. The combustion regulator used for the outer roll paper is preferably an alkali metal citrate, particularly potassium citrate and sodium citrate, which can be used alone or in combination. The pulp constituting the outer roll paper can be used as the pulp constituting the inner roll paper. The pulp volume is preferably 20 to 50 g / m2. The outer roll paper preferably has a weight per unit area of 50 g / m2 to 100 g / m2. In the present invention, calcium carbonate is added in the form of particles, and its particle size can be appropriately selected based on cost and papermaking difficulty, and it is preferably from 0.2 to 10 microns. According to the present invention, the cigarette having the tobacco portion which is double-wound with the inner roll paper and the outer roll paper has not only a small amount of sidestream smoke per unit time, but also a sidestream smoke volume per cigarette is reduced. Roll paper containing a large amount of calcium carbonate is a highly flammable one. When combined with an inner roll paper that does not substantially contain calcium carbonate, the burning speed is slower than when only the outer roll paper is used, and the amount of sidestream smoke per unit time is reduced. The amount of sidestream smoke per root can also be reduced. The burning speed of the cigarette of the present invention is preferably about 6 mm / min or more, and more preferably 7 mm / min or more. Such a burning speed can be achieved as described above, so that the content of the burning regulator of the inner roll paper is 0 to 1% by weight. The cigarette burning speed of the present invention usually reaches about 12 mm / min. And the burning speed of cigarettes

Description of the invention (6). From Table 1 As a result, it was found that the amount of sidestream smoke per unit time and the amount of sidestream smoke per cigarette of all the cigarettes of the present invention have been decreased as intended. In particular, the cigarette of the present invention significantly reduced the amount of sidestream smoke per unit time and the amount of sidestream smoke per cigarette as compared with the case where the paper was rolled only (Comparative Example 1). In addition, when comparing the cigarettes of the present invention and the cigarettes of Comparative Examples 3-1 to 3-4, it can be seen that when the content of calcium carbonate in the inner paper is less than 4% by weight, the amount of sidestream smoke per unit time and the amount of sidestream smoke per stick are obvious. decline. In addition, the burning speed of all the cigarettes of the present invention is above about 6 mm / min, and the amount of sidestream smoke per unit time and the amount of sidestream smoke per cigarette have decreased as expected. The various aspects of the present invention have been described above, but the present invention is not limited to aspects such as Xin. Of course, the above-mentioned various forms can be appropriately combined. According to the present invention, it is possible to provide not only a small amount of sidestream smoke per unit time, but also a small amount of sidestream smoke per cigarette.
