Description

Specification

Cigarette wrapping paper and cigarette

Technical field

The present invention relates to a cigarette having a short tobacco rod length and at least six smoking times (puffing times).

Background art

Conventionally, cigarettes with a short tobacco cut-out mouth length have been proposed for fire prevention and reduction of sidestream smoke, or to prevent carbon dioxide gas generation. For example, Utility Model Registration No. 3049857 contains a cigarette 1 in which the rod length per cigarette is reduced to half that of a normal cigarette in order to reduce the actual amount of carbon dioxide generated. Lets be disclosed. Japanese Patent Application Laid-Open No. 7-327654 discloses a cigarette power in which the rod length of the tobacco cut is shortened to 1 to 1.5 cm for fire prevention and sidestream smoke reduction; Let's do it. However, under the standard smoking condition (ISO), cigarettes on the market use 6 to 10 times of smoking (puffing), while those cigarettes do not Short cigarettes do not satisfy smokers because they smoke much less frequently.

Also, Patent No. 2,834,325 discloses that the tobacco cut density is set to 300 mg / cc or more and the burning speed of the tobacco cut rod is reduced to reduce the number of smoking. Many cigarettes are disclosed. Such cigarettes may be able to achieve a certain number of cigarettes, even with a shorter tobacco cut length. However, cigarettes with a tobacco shredding density of 300 mg Zcc or more are not suitable for high-speed production, and the amount of ash per cigarette smoke is small. It is no different from commercially available cigarettes.

It is an object of the present invention to provide a cigarette wrapping paper capable of slowing the natural burning rate, and to provide a cigarette with a short tobacco cut rod length that can satisfy a smoker. A new cigarette that is economical and environmentally friendly, with less ash and less sidestream smoke than conventional cigarettes To do.

Disclosure of the invention

The cigarette wrapping paper of the present invention has a basis weight of 17 to 21 gm2.

The composition is characterized in that the mixing ratio of the filler composed of calcium carbonate is 16 to 25% by weight, and the content of calcium carbonate is 3 g / m ² or more.

The cigarette of the present invention is characterized in that the tobacco cut is wound with the cigarette wrapping paper described above.

More specifically, the cigarette according to the present invention includes a cigarette portion in which a cigarette cut is wound with a cigarette, a finolator portion connected to one end of the tobacco portion, and a cigarette portion of the cigarette portion. The tobacco part covering the base end part and the filter part and the filter part are integrally connected, and are circumferentially located at a position away from the smoke-absorbing end of the filter part. A chipper having a plurality of bench-recess holes drilled along the tobacco, wherein the tobacco portion has a rod length of S30 to 46 mm, and is filled with tobacco cuts. The density is 180 to 270 mg Z cm 3, and the wrapping paper has a basis weight of 17 to 21 g Z m ² , and the mixing ratio of a filler consisting of canola carbonate is 16 1-2 5 weight ^_0/0, Ri carbonate calcium U der beam content 3 g / m ² or more, smoking times under standard smoking conditions The feature is that the number of times is six or more.

BEST MODE FOR CARRYING OUT THE INVENTION

The inventors of the present invention aimed at shortening the rod length of the tobacco cut, to reduce various factors such as tobacco wrapping paper, the diameter of the filter opening, the product airflow resistance during suction, and the like. Factors were analyzed. As a result, if a standard cigarette shred density is used in combination with materials used for normal cigarette manufacturing, a shorter cigarette shred rod will reduce the number of smokes and increase smoker satisfaction. It has been found that no can be obtained. This is because the cigarettes' free burning rate (the burning rate of the length of the tobacco cut-out head in a state where cigarettes are not smoked) is high at a standard tobacco chopping density. It turned out to be less. Therefore, it was expected that if the natural burning rate of cigarettes could be slowed, smokers would be satisfied.

The present invention provides a novel cigarette wrapping paper capable of slowing the natural burning rate of cigarettes, and a cigarette using such a wrapping paper.

The present inventors have found that the use of paper wrapping paper containing no auxiliary agent, having a basis weight as small as possible, and having a small weight percentage of filler (calcium carbonate) is a natural burning of cigarettes. It was found to be effective in slowing down the speed. However, in order to wind up the notch with a normal cigarette winding machine, the longitudinal tensile breaking load of the wrapping paper must be 1.0 kg / 15 mm or more and 2.0 kg / l 5 mm or less. Preference is given, but if the basis weight is too small, the tensile breaking load will be less than 1.0 kg / l 5 mm and the filler content will be reduced. It was also found that if too much, the tensile breaking load exceeded 2.0 kg / 15 mm, causing the ignited cigarette force to extinguish naturally.

Based on these findings, the present inventors have found that the basis weight is 17 to 21 g Zm2, the blending ratio of the filler composed of calcium carbonate is 16 to 25% by weight, We have developed cigarette wrapping paper with a um content of 3 g Z m 2 or more.

In addition, the basis weight is 17 to 21 g / m ² , the proportion of the filler composed of calcium carbonate is 16 to 25% by weight, and the content of carbonated calcium is 3 g. / m2 or more, the mouth length is 30 to 46 mm, the cigarette packing density is 180 to 270 mg / cm3, and the number of smoking in the standard smoking state is We developed a cigarette that is more than 6 times. The cigarette of the present invention has a tobacco cut packing density within a standard range of 180 to 270 mg / cm 3, and has a rod strength of 30 to 46 mm. Despite its short length (preferably 35-42 mm), more than 6 smokes can be achieved under standard smoking conditions.

In the present invention, by adjusting the filter portion and the tobacco portion, it is possible to provide a cigarette having a tar value that matches the taste of the smoker.

For example, in the design of high-tar cigarettes where the tar in mainstream smoke is 6 mg or more, the ventilation ratio (V f) from the ventilation holes in the fin- olator section is 30%. % Or less, and the blending ratio in the tobacco cut is preferably 20% by weight or less.

Tobacco shredding has the effect of lowering the temperature of smoke, but The garet has a short tobacco rod length, so the smoke temperature is unlikely to drop. In particular, when V f is low, it is remarkable, and the flavor is impaired. On the other hand, it is possible to improve the flavor by making the area where the tip paper connecting the notched rod and the freighter part covers the base end of the wrapping paper at least 10 mm. You.

On the other hand, in the design of a low targ tobacco with a tar in the mainstream smoke of 6 mg or less, more preferably 3 mg or less, the V f of the fretter section is 50% or more, and It is preferable that the composition ratio of the relaxing step is 20% by weight or more.

In addition, since the temperature of the smoke is unlikely to decrease, if the fent contains a menthol, the smoke will be more likely to evaporate due to the high-temperature smoke. This gives a cooler feeling than a normal mensole cigarette.

Hereinafter, examples of the present invention will be described.

As shown in Table 1, cigarettes were manufactured by variously changing the design of the tobacco section, wrapping paper, and part of the filter. For the tobacco section, the type of tobacco cut, rod length, percentage of relaxation cut, and tobacco cut density are adjusted. For wrapping paper, adjust the basis weight, filler content, calcium carbonate (CaCO ₃ ) content, auxiliary agent content, and air permeability (unit: Coresta unit). Reply For the filter part, the type of the filter, the length of the filter, and the ventilation ratio (V f) from the vent hole holes are adjusted.

In Table 1, the top three are comparative groups. In each group, the standard product is a commercial or similar cigarette and the control product is a cigarette. Cigarettes in which the rod length of the tobacco portion of the standard product is simply shortened, and Examples (1 to 3) are cigarettes included in the present invention. That is, in the cigarettes of Examples 1 to 3, the wrapping paper had a basis weight of 17 to 21 g Zm2, and the mixing ratio of the filler composed of calcium carbonate was 16 to 2 5% by weight, the content of calcium carbonate is 3 g Zm ² or more, and the tobacco part has a rod strength of 30 to 46 mm.

Table 2 shows, for each cigarette, airflow resistance, natural combustion speed, combustion length, natural combustion time, tar in mainstream smoke, amount of sidestream smoke, and number of smokes (number of puffs). ) Shows the measurement results. The burning condition of cigarettes was measured under the standard smoking condition (ISO).
