Description

592642 V. Description of the invention 0) [Technical field to which the invention belongs] The present invention relates to cigarettes, particularly to cigarettes that reduce the carbon monoxide content in mainstream cigarettes. [Prior Art] Various demands have been made on cigarettes today. One of them is to reduce the carbon monoxide content in mainstream cigarettes. The present applicant disclosed in Japanese Patent Laid-Open No. 10-99.96 (Patent No. 3 0 6 8 8 5). · If you use a embossed roll of paper to 'fill tobacco, not only Prevent the front end of the shredded tobacco from falling and reduce the mass ratio (C0 / T ratio) of carbon monoxide to coke t in mainstream cigarette smoke. The object of the present invention is to provide a further reduction in the carbon monoxide content in mainstream cigarettes, and as a result, a cigarette having a lower CO / T ratio can be obtained. [Mengming content] In order to achieve the above-mentioned purpose, the present inventors conducted detailed research on the application of cigarette paper rolling, and found that the cigarette paper was embossed to a certain depth, and The cut tobacco used can be cut to a certain width or more to achieve the above purpose. The present invention has been completed on the basis of this knowledge. 'That is, according to the present invention, a cigarette is provided which is characterized by having a tobacco section in which a shredded tobacco is rolled into a stick shape, the shredded tobacco has a cutting width of 1.2 miri or more, and the cigarette is partially or comprehensively. On the roll paper, from the inner surface, convex portions having a height of 1/3 or more of the thickness of the aforementioned roll paper are formed, and the convex portions are arranged toward the shredded tobacco. In the present invention, the cut width of the shredded tobacco is preferably greater than 2.0 mm.

The cigarette of the present invention uses mainstream cut tobacco and simultaneously uses roll paper which is given a predetermined embossing process, so that mainstream cigarettes contain carbon monoxide. Multiplying the amount decreases, so it also reduces the CO / T ratio. ^ The present invention will be described below with reference to examples, but the present invention is not limited to these. Example: Using the following specifications of shredded tobacco and rolled paper, a cigarette with the same structure as a cigarette with a filter (diameter: 8 mm, cut length · 5 9 mm, length of the ferrule: 2 5ίππ) is manufactured, and the rear end is connected Cut paper to make cigarette samples as shown in Table 1 below. Five cigarettes were made from each cigarette. <Tobacco>, tar. Value: 5mg is equivalent to a cigarette cut width: 0 · 8mm or 2mm <roll paper A (non-embossed processing)>, weighing: 22g / m2 · 'Filler: calcium carbonate filler Mixing ratio: 28 Mass% Accelerator: Sodium citrate Accelerator added amount: 1% by mass / degree: 3 2 μm Air permeability: 24C. U. 〈Rolled paper B (with embossing processing) &gt; Weighing capacity: 2 2 g / m 2 Filler: calcium carbonate

314382.ptd Page 10 592642 V. Description of the invention (7) As shown in Table 1, as long as the cut width of the cut tobacco is more than 1.2mm, or only embossing is performed on the roll paper, the carbon monoxide production can be reduced by 1 About 5%, and both of them can achieve a reduction rate of 41% of carbon monoxide content. From this result, it can be confirmed that the use of the predetermined cut tobacco of the present invention and the use of the predetermined embossed rolled paper can have a synergistic effect. As described above, according to the present invention, it is possible to provide a cigarette which can further reduce the carbon monoxide content in mainstream cigarettes.
