Definitions
- the present invention is intended to prevent a ignited cigarette from spreading to a fire from a burning part thereof so as to prevent a fire from being caused by carelessness of a smoker. About.
- the cigarette wrapper is made of cellulosic paper with a width of 2 to 20 mm so that it will not spread from the burning part.
- a cigarette with a self-extinguishing property provided by providing a band Japanese Patent Application Laid-Open No. 63-850200
- a band in which a flame-retardant substance is applied to tapaco paper is provided.
- cigarettes Japanese Patent Application Laid-Open No. 7-300079
- cigarette wrapping paper to which non-combustible material is attached is known.
- cigarette paper is provided with a highly flammable area and a low flammable area, so that normal smoking can be performed in the highly flammable area, but cigarettes can be smoked in the low flammable area. It is based on the knowledge that cigarettes extinguish themselves if there is a substance that comes into contact with them.
- Japanese Patent Application Laid-Open No. 60-59 199 discloses that in order to provide a smoking article having a low tendency to fire, a tobacco column is provided with two packaging materials each having a specific range of BMI (burnrate index) values. It discloses packaging. Out of the two packaging materials, the packaging material on the right side has a low air permeability of 1 cholester unit. In any case, Japanese Patent Application Laid-Open No. 60-59199 does not disclose or suggest that the thermal conductivity of the wrapper relates to the spreadability of cigarettes.
- BMI burnrate index
- An object of the present invention is to provide a low fire spread cigarette having the same combustion speed in the axial direction as a normal cigarette.
- a tobacco portion composed of a pillar-shaped tobacco filler, an inner wrapper wound around the outer periphery of the pillar-shaped tobacco filler, and an outer wrapper wound around the outer periphery of the inner wrapper is provided.
- the tobacco portion may exhibit a weight burning rate of 55 mg / min or more or a natural burning linear velocity of 5.0 mm / min or more.
- the inner wrapping paper may contain 0 to 0.5% by weight of a filler, and the inner wrapping paper preferably has air permeability of 5 to 30 coresta units.
- the pillar-shaped tobacco filler is wrapped in two rolls (inside). (A side wrapping paper and an outer wrapping paper). That is, in the cigarette of the present invention, the tobacco filler is wound by a winding material composed of an inner wrapping paper and an outer wrapping paper each having a specific thermal conductivity.
- the thermal conductivity of the wrapping paper can be determined by the filler (usually calcium carbonate or magnesium hydroxide) added to the base pulp, by increasing or decreasing the amount of pulp and by controlling the paper layer structure.
- the inner wrapping paper used in the present invention is characterized by high thermal conductivity (0.5 W WK-1 1m-1 or more).
- the inner wrapping paper is made by adding filler (usually calcium carbonate, magnesium hydroxide, etc. is used) to the base wrapping paper composed of pulp such as flax pulp or wood pulp. It is composed only by adding a trace amount (less than 0.5% by weight). It is preferable not to add a combustion regulator such as citrate.
- the inner wrapping paper may typically have a thermal conductivity of up to 0.6 W ⁇ K ⁇ 1 ⁇ m ⁇ 1.
- the inner wrapper preferably has a thermal conductivity in the range of 0.52 to 0.56 W ⁇ K-1 ⁇ m-1.
- the basis weight of the inner wrapping paper is not particularly limited, but it is usually preferably about 15 to 35 g / m 2 .
- the air permeability of the inner wrapping paper is not particularly limited, but it is desirable that the air permeability is high depending on the combination with the outer wrapping paper.
- the air permeability of the inner wrapper is preferably in the range of 5 to 30 corester units, more preferably in the range of 10 to 30 corester units. The higher air permeability of the inner wrapper increases the amount of air introduced from the wrapper into the cigarette, further dilutes the mainstream smoke and reduces the amount of carbon monoxide. Only decrease. Further, when the air permeability of the inner wrapping paper is high, the amount of air introduced from the wrapping paper into the cigarette increases, so that the number of ventilating holes formed in the chip paper can be reduced.
- the outer wrapper has a thermal conductivity of less than 0.5 W ⁇ K-1 m-1.
- the outer wrapping paper is based on pulp such as flax pulp or wood pulp, and controls the combustion of, for example, citric acid or a salt thereof (for example, a sodium salt or a calcium salt). 1% to 5% by weight of the agent. / 0 is preferred.
- the outer wrapping paper may usually have a thermal conductivity of 0.25 W'K-lm-1 or more.
- the outer wrapping paper preferably has a thermal conductivity in the range of 0.29 to 0.45 W'K-1m-1, preferably 0.29 to 0.35W * K- i m - arbitrariness preferred Ri good is and child having a thermal conductivity of 1 of the range.
- the basis weight of the outer wrapping paper is about 20 to 70 g / m 2, and the air permeability is about 100 core units and about 100 core units. Is preferred.
- the outer wrapping paper preferably contains a filler such as calcium carbonate or magnesium hydroxide at a ratio of 10% by mass to 60% by mass.
- the tobacco filler is generally used for cigarettes such as tobacco shreds, and the packing density is not different from that of conventional cigarettes.
- the cigarette of the present invention can be provided with a normal filter at one end of the tang portion.
- the cigarette of the present invention is clearly distinguished from the cigarette of the prior art in the thermal conductivity of the inner wrapping paper on which the tobacco filler is directly wound. Is done. Also, it is a feature of the present invention that it is not necessary to particularly limit the air permeability of the ⁇ side wrapping paper. In other words, the total air permeability of the inner wrapper and the outer wrapper is reduced by reducing the air permeability of the inner wrapper from 5 corestas to about 30 corestas. By doing so, it is possible to solve the problem that the ventilation effect from the wrapping paper in a conventional double wrapping cigarette is low.
- One of the features of the present invention is that a highly flammable wrapping paper is used for the outer wrapping paper, which has an effect of assisting the combustion of the flame-retardant inner wrapping paper.
- the cigarette of the present invention having a tobacco portion having such a configuration can exhibit a weight burning speed of 55 mg / min or more or a natural burning linear speed of 5.0 mm / min or more.
- Cigarettes A to L with the specifications shown in Table 1 below were manufactured by a conventional method. Cigarettes A to J are comparative examples, and cigarettes KL are products of the present invention. The only difference between the two is the specification of the wrapping paper and the configuration of the wrapping paper. The basis weight of each wrapper, the amount (wt%) of the filler (calcium carbonate), the amount (weight 0/0) of the combustion modifier (h E phosphorylated Li ⁇ beam), thermal conductivity and air permeability shown in Table 1 Show. Thermal conductivity was measured by the unsteady plane heat source method.
- the tobacco cut is a normal commercial American blend (packing density: 21.8 mg ⁇ cm-3), and the circumference of the cigarette is 24.8 mm.
- the length of the cigarette was 84 mm.
- the weight burning rate, linear burning rate and ignition rate were measured.
- Cigarette Weight The burning rate and the linear burning rate were measured with the cigarette placed sideways and without wind.
- the ignition rates in Table 2 are based on the simulated ignition test method reported at the National Institute of Standards and Technology (NIST).
- the present invention is a.
- the product of the present invention has an extremely low ignition rate while maintaining the weight burning rate similar to that of the conventional cigarette.
- a low fire spread cigarette having the same combustion speed in the axial direction.
- the cigarettes of the present invention have the same burning speed in the axial direction, so that the taste does not change during smoking.
