Description

Non-heated tobacco

The present invention relates to a non-heated cigarette that can taste the flavor of cigarettes by inhalation without igniting.

Cigarettes have been a favorite item for a long time, but in recent years they have been shunned from the surroundings due to sidestream smoke and odors produced by cigarette combustion. In order to reduce such a problem, Patent Literature 1 discloses a smokeless tobacco that can taste the flavor of tobacco without igniting. In this smokeless tobacco, a tobacco raw material impregnated with a tobacco extract flavor containing nicotine and a filter are filled in a hollow cylindrical container and sucked from an end portion on the filter side.

However, in order to reduce the cost or impart a flavor, a filter made of cellulose acetate is generally used. In the smokeless tobacco of Patent Document 1, since the tobacco raw material is basic, acetic acid is produced by liberation of the acetyl group of cellulose acetate, which may adversely affect the flavor. Furthermore, the amount of flavor components delivered decreases due to the effect of sorption due to the chemical affinity between the flavor components and the filter material. Such cellulose acetate is often used in general cigarette filters.

In order to solve the above problems, as a filter resin, a PAN (polyacrylonitrile), EVOH (ethylene vinyl alcohol copolymer resin) or the like continuously foamed, or a resin particle aggregated with a binder is used. In either case, it is very expensive. Similarly, it is possible to use a filter made of a metal, but this is also expensive.

It is a schematic sectional drawing of the non-heating-type cigarette which concerns on this invention. It is an experimental data which shows the delivery amount of the flavor component of the non-heating type tobacco which concerns on this invention. It is an experimental data which shows the base-proof performance of the non-heating type cigarette which concerns on this invention. It is an experimental data which shows the sending amount of the flavor component when changing the filling amount of a tobacco grain.

As shown in FIG. 1, the non-heated cigarette 1 according to the present invention is a so-called smokeless cigarette, and includes a snuff tobacco material 2, a holder (tubular body) 3, and a filter 4. The snuff material 2 is obtained by mixing a tobacco leaf and a fragrance and adding a flavor component of tobacco. The holder 3 has a hollow and substantially cylindrical shape, and a tapered mouthpiece portion 5 is formed at one end on the mouthpiece side. The holder 3 is filled with a snuff material 2 and a filter 4. More specifically, the snuff material 2 and the filter 4 are filled in the holder 3 via the hollow cylinder 6. However, the tobacco material 2 may be filled directly into the holder 3. The hollow cylinder 6 is filled with a snuff tobacco material 2 and a filter 4 side by side with a partition material 7 having air permeability interposed therebetween. At both ends of the hollow cylinder 6, a lid material 8 having air permeability is fitted. In this state, the filter 4 is inserted into the holder 3 so as to be on the mouthpiece 5 side. A cap 9 having an opening 10 is fitted into the end of the holder 3 opposite to the mouthpiece 5. The holder 3 may be replaced with a cartridge in which the hollow tobacco 6 is filled with the snuffed tobacco material 2, the filter 4 is arranged with the partition material 7 being spaced, and both ends are closed with the lid material 8. Further, the filters 4 may be installed at both ends of the hollow cylinder 6 so that the user can use the hollow cylinder 6 in any direction with respect to the holder 3 without any problem.

The user of the non-heated cigarette 1 tastes the flavor of the snuffed tobacco material 2 by sucking air from the mouthpiece 5. When air is sucked from the mouthpiece 5, air flows into the holder 3 from the opening 10 through the lid member 8. Then, the air comes into contact with the snuffed tobacco material 2 and the flavor of the snuffed tobacco material 2 is included in the air. The air containing the flavor passes through the filter 4 and is sucked by the user from the mouthpiece portion 5, so that the user can taste the flavor. When the flavor is lost, the hollow cylinder 6 is taken out of the holder 3 and replaced with a new one.

The filter 4 is made of a pulp material. Thereby, it can suppress that the flavor which the snuff tobacco material 2 contains is sorbed by the filter 4. Therefore, the flavor of the tobacco material sniffed in the air sucked from the mouthpiece portion 5 can be surely included. Moreover, by using a pulp raw material, increase in ventilation resistance can be prevented and a stable suction feeling can be given to the user. Furthermore, the filter 4 can be manufactured at low cost by using a pulp material. In addition, you may use a pulp nonwoven fabric for the filter 4. FIG.

As apparent from FIG. 2, the amount of the flavor component delivered by the filter using the pulp material (the amount that the flavor component passes through the filter) is higher than that of the filter using the cellulose acetate material that has been conventionally used. There are many. In addition, this delivery amount has shown the result of having computed the delivery amount when using the filter of a cellulose acetate raw material as 1.0. In this experiment, the flavor component was nicotine. The pulp material filter used was a paper board creped and woven into a web. The snuff material is obtained by sieving tobacco particles having a particle size of 0.5 mm to 1.18 mm from those obtained by pulverizing the leaves of the tobacco, and adjusting the mixture by adding potassium carbonate and fragrance after humidification and heat treatment. Using. The filling amount of snuff material is 0.27 g. A hollow cylinder having an inner diameter of 8 mm was used. Filter cigarettes are generally known to have higher filtration rates for tar and nicotine in the case of the same ventilation resistance, but in the case of non-heated tobacco, the flavor component is more efficient. 2 can be seen from FIG. As the flavor delivery amount, an average value per one time when suctioned 40 times at 15 second intervals with a capacity of 35 cc / 2 seconds was used.

Also, as is clear from FIG. 3, acetic acid is not liberated in the filter using the pulp material compared to the filter using the cellulose acetate material used in the past. In this experiment, according to JIS K 7114, 10 ml of 50 wt% aqueous potassium carbonate solution (pH 14.1) was used, soaked 10 filters each cut to 5 mm length, and the filter after one month had passed in an environment of 55 ° C. in a sealed condition. Changes in physical properties and the like were measured. In the filter made of cellulose acetate material, it can be seen that the pH of the solution is greatly lowered and acetic acid is liberated. On the other hand, as described above, in the pulp material filter, acetic acid is not liberated and the pH is not significantly changed. In the case of non-heated cigarettes, the release of acetic acid may greatly affect the flavor, so it is understood that a filter using a pulp material is superior to give the user a proper flavor. . A capillary electrophoresis measuring device was used for measuring the acetic acid concentration in the solution.

On the other hand, the longitudinal direction of the airflow resistance of the filter 4, it is preferred for the filter length 5mm are 5mmH _₂ O ~ 15mmH ₂ O. In the non-heated cigarette 1, the overall ventilation resistance is defined by the sum of the ventilation resistances of the snuff material 2 and the filter 4. The ventilation resistance in the non-heated cigarette 1 cannot be smoked by a person if it is too high, so it is necessary to set it below a desired value. For this reason, it is necessary to set the ventilation resistance of the snuff material 2 and / or the filter 4 low. When the ventilation resistance of the snuff tobacco material 2 is lowered, it is conceivable to reduce the filling amount of the snuff tobacco material 2 or change the particle size. However, it is not preferable to reduce the filling amount of the snuff material 2 because it leads to a decrease in flavor. Moreover, the change of the particle size also has an influence on the flavor, which is not preferable. For this reason, setting the ventilation resistance of the snuff tobacco material 2 low is not preferable from the viewpoint of influence on flavor.

For this reason, in order to set the ventilation resistance of the whole non-heating type cigarette 1 low, the ventilation resistance of the filter 4 must be lowered. The filter 4 prevents the spilled tobacco material 2 from spilling in cooperation with the partition member 7 and the lid member 8 described above, and therefore requires a ventilation resistance to such an extent that the spilled-off does not occur. Therefore, the ventilation resistance of the filter 4 needs to be as low as possible from the viewpoint of ease of sucking and can prevent the snuff tobacco material 2 from falling out. With this in mind, the present inventors have found that it is optimally 5mmH _₂ O ~ 15mmH ₂ O with respect to the filter length 5mm, as described above.

For the non-heated cigarette 1 shown in FIG. 1, sensory evaluation showed that the optimum ventilation resistance was 40 mmH ₂ O to 80 mmH ₂ O. Table 1 below shows the results of evaluation by sucking two types of non-heated cigarettes with 16 testers having different ventilation resistances.

If a non-heating type tobacco unheated type tobacco and airflow resistance mmH 2 _O airflow resistance 40mmH 2 _O were compared by the test person was no difference in the evaluation of the test person. However, non-heating tobacco and non-heating tobacco and airflow resistance 80mmH ₂ O airflow resistance mmH ₂ O, between a non-heating type tobacco unheated type tobacco and airflow resistance 100 mm H ₂ O airflow resistance 80mmH ₂ O In the comparison of, there was a difference in the evaluation. Of these, it was also found that testers tend to prefer non-heated cigarettes with low ventilation resistance. Specifically, rather than non-heating type tobacco airflow resistance 100 mm H ₂ O are preferred better unheated type tobacco airflow resistance 80mmH ₂ O. Also, rather than a non-heating type tobacco airflow resistance 80mmH ₂ O are preferred better unheated type tobacco airflow resistance mmH ₂ O. However, the difference in taste testers between the non-heating type tobacco unheated type tobacco and airflow resistance 40mmH 2 _O airflow resistance mmH 2 _O is not substantially.

Table 1 also shows that when non-heated cigarettes with different ventilation resistances are compared, if there is a difference of 20 mmH ₂ O in the ventilation resistance, the tester can identify the difference in ventilation resistance.

As described above, the ventilation resistance of the non-heated tobacco is preferably 80 mmH ₂ O or less, specifically 40 mmH ₂ O to 80 mmH ₂ O.

On the other hand, in the non-heated cigarette 1 shown in FIG. 1, the weight of the snuff material 2 needs to be 0.2 g or more on a dry basis. Here, FIG. 4 shows the relationship between the amount of flavor components delivered from non-heated tobacco in a single puffing operation and the amount of tobacco particles filled (dry basis). In addition, the flavor component represents the component (specifically nicotine) used as a flavor parameter | index among the tobacco components contained in a tobacco grain.

Here, the specification of the snuff material 2 having the relationship shown in FIG. 4 was as follows.
Tobacco grains: A mixture obtained by adding an additive such as carbonate (potassium carbonate) and a fragrance after moistening and heat-treating the pulverized tobacco leaves of Burley seeds.
Particle size of tobacco particles of 90% by weight or more: 0.212 mm to 2.0 mm
Inner diameter of hollow cylinder 6: 7 mm

As can be seen from FIG. 4, the amount of flavor components to be delivered increases as the amount of tobacco particles increases, but if the amount exceeds 0.2 g, there is almost no change from the case where the amount is 0.3 g. . Therefore, the filling amount of the snuff material 2 is preferably 0.2 g or more on a dry basis.

In the non-heated tobacco 1 shown in FIG. 1, when the inner diameter of the hollow tube is 6 mm to 8 mm, the snuff tobacco material 2 has a particle size of 0.5 mm to 2 mm, and the snuff tobacco material 2 has a weight of 0.2 g or more on a dry basis. The snuffing material 2 has a ventilation resistance of 25 mmH ₂ O to 75 mmH ₂ O.

As described above, when the snuffing material 2 has an airflow resistance of 25 mmH ₂ O to 75 mmH ₂ O, the airflow resistance of the filter of the present invention is 5 mmH ₂ O to the filter length of 5 mm, which is the minimum length in manufacture. if 15 mmH ₂ O, for the entire flow resistance of the non-heating type tobacco 1 it is possible to realize a 40mmH _₂ O ~ 80mmH ₂ O is the optimal ranges mentioned above.
