Abstract

The invention relates to cigarettes and similar smoking articles m. The aim of the invention is to reduce sidestream smoke by reducing the content of harmful components. The smoking article contains a rod 1 of smoking material enclosed in a paper wrapper 2, the air permeability of which is not more than 20 Coresta, a filter 3. attached to the rod 1 by an end wrapper 4. Smoking material contains at least 20% by weight of expanded tobacco, the density of its packing in the rod 100-260 mg / cme, with the provision of at least six shakes and a sidestream smoke output of not more than 17 mg of solid particles free of water and nicotine. 3 E.

which is no more than 20 coresta, filter 3, the smoke flow respectively is

32.0; 5.43 and 63.7 mg. The average number of heads of the first control cigarette is 10.

When the second comparable control cigarettes containing as a tobacco-filler 100% of the expanded sliced leaf tobacco tobacco, the same as n tobacco-filled

attached to the rod 1 through the end wrapper 4.

The smoking material contains at least 20% by weight of expanded tobacco, its packing density in the rod is 100-260 mg / cm3, ensuring that no more than six tackles are smoked on the machine and no more than 17 mg of solids free in the sidestream smoke from water and nicotine (TFSVN), and not more than 35 mg of mono-, carbon monoxide. The circumference of the rod of smokable material is 10-30 mm, the volume of expanded tobacco used in the smoking material is increased by at least 75% of its original volume, and the proportion of expanded tobacco is 100-175 mg / cm3.

the body, and additionally containing ordinary cigarette paper, is the same as that of the first control cigarettes, smoothed out according to the smoking regimen, the average total yield per cigarette PSTVN, PNA and CO in the sidestream smoke is 18.2; 2.25 and 39.4 mg. The average number of second control cigarettes is 6.0.

the body, and additionally containing ordinary cigarette paper, is the same as that of the first control cigarettes, smoothed out according to the smoking regimen, the average total yield per cigarette PSTVN, PNA and CO in the sidestream smoke is 18.2; 2.25 and 39.4 mg. The average number of second control cigarettes is 6.0.

When untwined sliced leaf tobacco is used for

on the circumference of the rod 24.75 mm, the filter 3 is made of cellulose acetate, and its length is 20 mm0

The smoking material of rod 1 includes a cut tobacco filler consisting of 100% cut tobacco tobacco leaves, which is expanded by using a strong swelling process, known as the DIET process. The filler tobacco density is 174 mg-cm 3. Wrap 2 has an air permeability of less than 1.0 Coresta units, it contains 4.3% calcium carbonate, but does not have additives that affect its combustible properties.

When such cigarettes are spun under standard machine smoking conditions to a finite cigarette rod stub length of about 8 mm, then the average total output per cigarette of the side stream of TFCHVN, full nicotine alkaloids (PNA) and carbon monoxide (CO) is respectively 7.2 ; 0.84

third comparable control cigarettes containing rod wrappers with

low permeability from paper with a permeability of less than 1.0 Coresta units, and third control cigarettes are crammed, again under standard machine smoking conditions until a stub length of 8 mm is obtained, the total average output per cigarette PMTVN, PNA and CO in the sidestream smoke is respectively 19.9; 3.62 and 47.8 mg.

From the results obtained when smoking control cigarettes, it can be easily calculated that, based on a straight linear proportion, the expected average total yield of TPSHVN, PNA and CO in the sidestream smoke for comparable cigarettes containing as 100% expanded tobacco filler, the same as the tobacco filler and the wrapper of the said paper with a permeability less than 1.0 units of Coresta were 11.3 per cigarette, respectively; 1.48 and 29.6 mg

(for example, the calculated value of TSTVN is 19.9 "(1-0.43) 11.3, while the value of 19.9 is the value of TSTN for the third control cigarettes, and the value of 0.43 is the value of TLSNV for the first control cigarettes minus the TSCVN value for the second control cigarettes, expressed as a fraction of the TSCVN value for the first control cigarettes, i.e., as the ratio of the decrease in TSCVN. is respectively 7.2; 0.84 and 19 mg.

Thus, the total average yield of TPSVN in the sidestream for cigarettes, which are cigarettes according to the invention, is 36% less than the calculated value. If we look at the total average output of the PNA and CO in the sidestream, the values measured for the proposed cigarettes are 43% and 36% less than the calculated values, respectively. Such cigarettes exhibit a certain synergistic effect of reducing sidestream smoke components.

In tab. Table 1 provides detailed information on the average total yield of sidestream smoke components and the number of puffs for cigarettes according to the invention. Cigarettes containing a wrapper of paper labeled A (this is a proposed cigarette) "Other cigarettes are comparable, except for the content of the paper labeled B and C, respectively. These si are

the garets were smoking according to the above mentioned smoking regimen.

In tab. 2 provides detailed information on papers A to C.

In tab. 1, the letter S under the values given in columns 5-7 indicates a synergistic effect of reducing the smoke components in the sidestream. As you can see from the table. 1, synergism for reducing sidestream components is the hallmark of each cigarette design using paper wrappers from A to C.

Cigarettes for which the values of the components in the sidestream smoke are presented in table. 3, comparable to cigarettes according to Table. 1, except that the first cigarettes

contain tobacco filler in 50% of expanded tobacco, and this tobacco is again a tobacco expanded according to the DIET method. The remaining 50% of tobacco filler was provided with unweighted tobacco slices and leaflets. The density of the tobacco filler is 212 mg-cm 3. The predicted values of the components in the sidestream smoke are given in table. 3, are calculated from the measured feed values of the sidestream smoke components for the first, second i. the third control cigarettes, as well as above for cigarettes according to table 1. As can be seen from columns 5-7 in the table. 3, the synergistic effects of reducing components in the sidestream smoke are manifest in all cigarettes about

Cigarettes for which the values of the components of the sidestream smoke are presented in table. 4, are comparable to cigarettes according to Table 1, except that the first cigarettes contain tobacco filler from 100% cut leaf tobacco, which is expanded by using a strong swelling process. The density of the tobacco filler is 140 mg-cm. 3. The values of the components in the sidestream smoke are given in table. -, calculated from the measured feed rates of the sidestream components for the first, second and third control cigarettes in the same way as for cigarettes according to Table. 1. As can be seen from columns 5-7 of the table. 4, the synergistic effects of the reduction of the smoke components in the sidestream flow are manifested by all cigarettes according to Table. 4, with the exception of cigarettes containing paper, for which the supply of TTSVN in the sidestream was not synergistic.

Cigarettes for which the values of the components in the sidestream smoke are presented in the scoreboard 5 are comparable to cigarettes according to Table 1, except that the circumference of the first cigar g is 17 mm. The predicted values of the components in the sidestream smoke are given in table. 5 are calculated from the measured component feed rates in the sidestream for the first, second and third control cigarettes in the same way as above for cigarettes according to

tab. 1, except that in this case, the first, second, and third control cigarettes are 17 mm in circumference. The cat can be seen from columns 5-7, the inertial effects of reducing components in the sidestream smoke are shown by cigarettes according to the scoreboard 5.

Paper H, listed in Table. 5, has an air permeability of 1.0 Coresta units, and a specific weight of 22.3 2. Paper H contains 1.3% calcium carbonate and 13.8% titanium dioxide.
