LT3253B - Paper for cigarettes and smokers - Google Patents

Abstract

Cigarette paper having a total filler content of about 20 percent by weight or less, and the filler content is capable of significantly reducing the generation of sidestream smoke. The weight of the paper is about 30 grams per square meter or more. Cigarettes made using such paper provide a synergistic reduction in the amount of the component in the generation of sidestream smoke, compared to controls. The invention also describes paper with various combustible additives.

Description

The present invention relates to a wrapping paper for wrapping smoking material and the production of cigarette cores. Hereinafter, such wrapping paper is referred to as cigarette paper.

Previously, cigarette papers were offered that contained magnesium oxide, introduced to reduce the noticeable sidestream smoke compared to that emitted by regular cigarette papers. This appears to be of poor quality, made using sidestream smoke reduction papers, which have been noted by smokers to impart an extra flavor to the mainstream smoke, and also exhibit poor ash formation.

The aim of this invention is to create cigarette paper with reduced sidestream smoke.

cigarette paper, For example, cigarettes

Another object of the present invention is to provide cigarettes with reduced sidestream smoke or other smokers with similar reduced sidestream smoke.

The present invention includes cigarette paper comprising a total filler content of about 20 percent by weight or less, i.e., a filler proportion that provides a significant reduction in the generation of sidestream smoke, and having a paper weight of about 30 grams per square meter or more.

The present invention also includes such smokers which include in the main composition of the smoking material object and the wrapping paper surrounding the smoking material a total amount of filler of not more than 20 percent by weight, and which filler is present in such a proportion as to provide effective reduction of sidestream smoke, and the weight of the paper is 30 grams per square meter or more.

The filler that provides a significant reduction in side flow is preferably magnesium oxide and/or magnesium hydroxide or chalk with a very smooth surface or a mixture of these components. The magnesium oxide used for the purposes of this invention is preferably the reactive fraction.

As a supplement to the filler, which significantly reduces side flow, ordinary chalk can also be included in the filler composition. When adding chalk to the filler composition, its amount is best selected at about 12 percent - 3 percent of the weight of the paper, and usually its amount does not exceed 10 percent of the weight of the paper.

The optimum amount of filler that significantly reduces the main flow is in the range of about 4 percent to 18 percent by weight, but the most optimal ratio is about or greater than 7 percent by weight.

The paper has a permeability inherent to it, and is related to the binding flux, and is preferably about 10 Coresta units or less, and more preferably about 5 Coresta units or less.

The air permeability of paper, expressed in Coresta units, is the amount of air, expressed in cubic centimeters, that passes through one square centimeter of paper in one minute at a constant pressure difference of one kiloPascal.

Porous cigarette paper consists of interconnected fibers that are exclusively or mainly cellulose fibers mixed with filler particles, such as calcium carbonate. The holes in the matrix of fibers or filler have a width of the order of one micrometer, moreover, this size is very small compared to the thickness of the paper /usually from 20 to 50 micrometers/ and the air flow through such holes is determined by the action of bonding forces. In addition, if the paper turns out to be perforated during its production process, the perforations are relatively large and usually have a width of the order of the thickness of the paper. In addition, the air flow through such perforations is determined by energy forces.

Thus, it can be concluded that when the permeability of perforated paper is determined by the permeability determination method, according to Coresta, and the obtained values are the sum of the permeability, which causes continuous flow through the holes in the paper, formed in the paper production process, and the permeability, which causes inertial flow through the perforation. The paper has the same 2 formed permeability, if although it is not perforated, the more it has a supplement for small holes with continuous flow, has large holes with inertial flow, in addition, the latter holes can be called staple holes. Paper with such properties can appear, for example, in an unsatisfactory paper production technology process.

The total air flow through the paper can be expressed by the following formula:

Q = ZAP + Z^iPJn where “1

Q - denotes air flow (cm min),

A - denotes the area of paper (cm ² ) through which the air flow is directed,

P - denotes added (kiloPascals), 4 for paper pressure difference Z - marks paper permeability, leading to continuation 5 flow through the holes formed by the paper in the production process , expressed Coresta in units (cm min ¹ kiloPascal), z ¹ - marks paper permeability, which determines inert- 10 what is the flow through perforations and/or pins punctures (cm min' ¹ kiloPascal ¹ ) and

n - denotes a constant for this set of perforated holes or staples, where 0.5<n<l.0, moreover, the exact value of n depends on the sizes of the perforations or staples.

The total permeability of paper, including the permeability due to perforations and/or the permeability due to staples, is equal to Z + Z ¹ , and the relative values of these values for this type of paper can be obtained by measuring the air flow through the paper, selecting the differences in pressure applied to the paper, and quantitatively is the ratio of the Q/P value, in the above formula, to the value, respectively, of the average perforation size - staples in this type of paper.

It is understood that the value of ten Coresta units mentioned above in relation to the cigarette wrappers of the present invention is intended to be a continuous flow permeability of such wrappers. It is also understood that it is possible for a cigarette wrapper of the present invention to have a total permeability, i.e., a permeability determined using the Coresta method, exceeding ten units if the paper from which the wrapper is made has perforations and/or staples.

As a rule, the maximum weight of all filler in paper is about eight grams per square meter.

The weight of the paper is usually about 35 grams per square meter or more, and a better value is about 40 grams per square meter or more.

Preferably, the paper according to the invention contains combustion additives in the range of about two to ten percent by weight.

Additives which have proven to be sufficiently effective in achieving the purpose of this invention include sodium acetate, tripotassium citrate, sodium orthophosphate and potassium tartrate. The salts of the combustible additives may be provided in either alkaline, acidic or aqueous solutions.

Combustion additives can be either combustion accelerators or combustion retardants.

The smoking materials of the invention may include a specified proportion of expanded tobacco. The expanded tobacco may have a bulk density in the range of 100 grams cm ³ to 175 grams cm ³ . The proportion of expanded tobacco in the smoking material should be at least ten percent by weight, and preferably at least 20 percent by weight, and more preferably at least 30 and even 40 percent by weight.

The length of the smoking material core of the smokers according to the present invention is suitably at least 45 millimeters, more suitably at least 55 millimeters. The smoking material cores should preferably have uniform cross-sectional shape and dimensions along their entire length.

s

If, as is usual in the case of cigarettes and similar tobacco products, the core of the smoking material of the product according to the present invention has a uniform circular cross-section, the circumference of the core may be from 10 to 30 millimeters. While significant and commercially useful reduction of sidestream smoke from cigarettes according to the present invention is achieved when the core circumference is 25±5 millimeters, even better results are obtained when the core circumference is less than this value, reaching up to 10 millimeters. Preferably, the circumference of the cigarettes in the form of a core does not exceed 12.5 millimeters according to the present invention.

When smoking cigarettes under standard mechanical smoking conditions, the present invention ensures at least five puffs, preferably at least six puffs.

Preferably, smokers according to the present invention have a filter or mouthpiece attached to the core of the smoking material at one of its ends.

Smokers can activate the ventilation device according to the present invention.

It should be noted that the smokers according to the present invention may have a wrapper comprising one or more sheets covering the wrapping material.

EXAMPLE 1

The first batch of cigarettes tested consisted of cigarette cores measuring 64 millimeters in length and 24.73 millimeters in circumference, and cellulose acetate filters measuring 20 millimeters in length. The density of the cut tobacco filling the cigarette cores was 256 milligrams per cubic centimeter. The cigarettes were wrapped in regular cigarette paper with a permeability of 45 Coresta units, with an average weight of 37 grams per square meter. The paper contained 28.8% calcium carbonate filler. These cigarettes were labeled Cigarettes 1.

The second control batch of cigarettes, designated Cigarettes 2, consisted of cigarette cores 64 millimeters long, with a circumference of 24.82 millimeters, and 20 millimeters long cellulose acetate filters. The cigarette core filler was made of cut tobacco with a density of 261 milligrams per cubic centimeter. The cigarette wrappers were made of paper with a permeability of 61 Coresta units and a weight of 34.8 grams per square meter. The paper contained 15.4 percent calcium carbonate and 11 percent magnesium oxide.

*

The third control batch of cigarettes had cigarette cores 64 millimeters long with a circumference of 24.82 millimeters and filters of acetate cellulose 20 millimeters long. The filler, made of cut tobacco, had a density of 252 milligrams per cubic centimeter. The cigarettes were wrapped in paper with a permeability of six Coresta units, having a weight of 35.6 grams per square meter. The paper incorporated a 22.4% calcium carbonate filler.

Cigarettes A were manufactured as smokers according to the present invention. These cigarettes were formed from cigarette cores 64 millimeters long, circles 24.83 millimeters long and cellulose acetate filters 20 millimeters long. The filler, made of cut tobacco, had a density of 248 milligrams per cubic centimeter.

The cigarette cores were wrapped in paper with a permeability of 7 Coresta units and a weight of 36.6 grams per square meter.

LT 32S3 B

The paper had 4.9% calcium carbonate filler and 10.5% magnesium oxide filler.

Cigarettes 1-3 and cigarette A were smoked under standard mechanical smoking conditions, i.e., puffing at a volume of 35 cubic centimeters for two seconds every minute to a tobacco core length of 6 millimeters, and the total sidestream flow for each type of cigarette was measured using the method without nicotine and water (PMWNF), total nicotine alkaloids (TNA), carbon monoxide (CO) and carbon dioxide (CO ₂ ). The average values measured are shown in Table 1.

The predicted values presented in Table 1 for cigarette A were calculated from the measurement results for cigarette 13. In this example, the predicted values were calculated based on the percentage reduction provided by each control cigarette corresponding to the sidestream components of the first control cigarette.

For example, the predicted PMWNF size for cigarette A is calculated as 28.6 (1-0.12)(1-0.09) = 22.9. 28.6 is the PMWNF size for the first control cigarette. 0.12 is the PMWNF size for the first control cigarette minus the size of the second control cigarette expressed as a fraction of this size for the first control cigarette, i.e., the PMWNF reduction ratio. 0.09 is the PMWNF reduction ratio for the third control cigarette relative to the first control cigarette.

The measured PMWNF size for cigarettes A was 20.3. Thus, it can be seen that the cigarettes according to the present invention have a synergistically reduced PMWNF size value. The synergistic reduction is also observed in the total amount of nicotine alkaloids, carbon monoxide and carbon dioxide.

EXAMPLE 2

The first control batch of cigarettes (Cigarettes 1) and the second control batch of cigarettes (Cigarettes 2) were the same as in Example 1.

The third control batch of cigarettes - Cigarettes 4 were cigarette cores 64 millimeters long, 24.77 millimeters in circumference. The density of the cut tobacco filler in the cigarette cores was 252 milligrams per cubic centimeter. The cigarette cores were also wrapped in paper with a permeability of 6 Coresta units, weighing 36.7 grams per square meter. The paper had a calcium carbonate filler of 19.6%.

Cigarettes A were manufactured in accordance with the present invention and were equivalent to Cigarettes A in Example 1.

Cigarettes 1, 2, 4 and A were smoked under standard mechanical conditions and the following sidestream measurements were made for the cigarette: PMWNF, TNA, CO and CO ₂ . The average values measured are given in Table 2, which also shows the predicted values for each sidestream component. It can be seen that the cigarettes according to the present invention have a synergistic reduction in the sidestream smoke components for each of the tested components.

The following examples illustrate the levels of components in sidestream smoke produced by smoking tobacco products wrapped in paper made in accordance with the present invention. In each case, the physical properties of the paper wrappers varied to some extent.

EXAMPLE 3

A batch of cigarettes was made consisting of regular cigarette cores with a standard circumference of 59 millimeters and cellulose acetate filters of 20 millimeters in length. The average density of the filler, from cut tobacco, in the cores of these cigarettes was 205 milligrams per cubic centimeter. A uniform tobacco blend was used for the manufacture of all cigarettes and included about 40% of the expanded tobacco DIET sheets. Table 3 presents data for each of the papers used to manufacture cigarettes A to E. The paper was treated with an increased concentration of sodium acetate. The paper used to manufacture cigarette A is identical to that used to manufacture cigarette A in Examples 1 and 2.

Each of these cigarettes was smoked in a standard device, and the sidestream smoke component measurements were made, as shown in Table 4. The control cigarette, Cigarette 5, was a product of similar dimensions, with a tobacco density of 246 milligrams per cubic centimeter. The paper used to make the cigarettes had a permeability of 50 Coresta units and a basis weight of 29 grams per square meter. The paper contained 21% chalk and 2% sodium citrate and potassium citrate.

Cigarette batches F to H were produced, having the same sizes as those of Example 3. The cigarettes of Example 4 used the same tobacco blend as in Example 3, with the addition of 40% of the expanded tobacco DIET sheets. The paper for cigarettes A was treated with trisodium citrate levels of 3.3%, 5.2% and 10.1%, respectively.

The control cigarette was the same as in Example 3.

Table 5 presents the amounts of sidestream smoke components when cigarettes were smoked using a standard smoking device. For comparison, the amounts of sidestream smoke for cigarettes A and C are also included in the table.

In this series of cigarettes the tobacco blend was the same and the paper was treated with citrate. In cigarettes F to H the density was reduced from the average level of 205 milligrams per cubic centimetre for cigarettes A and C to 188 milligrams per cubic centimetre, 190 milligrams per cubic centimetre and 192 milligrams per cubic centimetre, in order to determine whether satisfactory physical characteristics of the products were guaranteed by such a reduction.

The results obtained show that treatment with tripotassium citrate at a concentration equivalent to sodium acetate provides an effect equivalent to that obtained with sodium acetate. In the mainstream smoke stream (these data are not provided in the application), at equal concentrations of tripotassium acetate and sodium acetate, a small but nevertheless noticeable reduction is observed for CO/PMWNF paper treated with citrate compared to paper treated with sodium acetate.

EXAMPLE 5

This series of cigarettes used paper according to the present invention, which also has a reduced weight. The characteristics of the paper used for the production of cigarettes are given in Table 6. The paper was treated with sodium acetate.

EXAMPLE 8

A batch of cigarettes was produced to illustrate the effect of the paper produced according to the present invention on sidestream smoke components, using such paper for wrapping smoking tobacco cores.

The batch of cigarettes included a series of control cigarettes, specifically Cigarettes 1, 2, 3, 4, mentioned earlier in this application. In addition, control Cigarettes 6, 7, 8 and 9 were produced. The paper for Cigarette 1 was treated with combustible additives, such as sodium acetate, tripotassium citrate, potassium orthophosphate and potassium tartrate, as shown in Table 12. The concentration data reported are expressed as a weight percentage of the total paper weight in g/m of the treated paper.

Cigarettes wrapped in paper prepared according to the present invention 5 were produced by treating the paper used in the manufacture of Cigarettes A with the same combustible additives as used in the manufacture of Cigarettes 6-9. The percentage of the treated component is given in Table 13 and is a weight percentage of the weight of the treated paper. Cigarettes of this batch are designated by the indices AA - DD.

It can be seen that there is a relatively good correlation between the concentrations of the processed mixture in the control and test cigarettes.

The physical characteristics of such cigarettes are shown in Table 14 below. The dimensions of these cigarettes were as usual, i.e. the tobacco core was 64 millimetres long and of standard circumference, and the cellulose acetate filter was 20 millimetres long.

The same tobacco blend was used as in Examples 1 and 2, i.e., 22% stems, 3 percent tobacco leaves and 75 percent leaf tobacco, of which 12 percent was expanded leaf tobacco DIET.

These cigarettes were smoked in a standard smoking device, and measurements of the components in the sidestream smoke were made. Table 15 presents the results obtained for control Cigarettes 6-9.

Using the data presented in Table 15 and the data for the other control cigarettes, namely Cigarettes 1, 2, and 3, it is possible to calculate the exact amount of components in the sidestream smoke, as was done

In Example 1. Furthermore, given that there are currently three variable paper performance parameters, i.e. the effect obtained by using the magnesium oxide filler, the effect by reducing air permeability and the effect obtained by using the combustible additive, the predicted value of PMWNF for Cigarettes AA is calculated as follows: 28.6 (1-0.12)(1-0.09)(1-0.21) = 18.1, where 0.21 is the PMWNF value for Cigarettes 1 minus this value for Cigarettes 6, expressed as a fraction of the value for Cigarettes 1.

The measured value of PMWNF for AA cigarettes was 13.6. Thus, it can be seen that cigarettes manufactured according to the present invention have a synergistic reduction in PMWNF.

Table 16 presents the calculated and measured values for Cigarettes AA - DD. Control batch 3 of cigarettes used in these calculations as in Example 1.

EXAMPLE 9

A paper was produced with a weight of 45-50 grams per square meter and a permeability of about 5 Coresta units. The paper contained 6 percent to 8 percent magnesium oxide and about 3-5 percent calcium carbonate. This paper was designated EE. This paper was processed to a degree that it contained 4.5 percent sodium acetate, and the resulting paper was designated FF. The FF paper was electrostatically perforated to a total permeability of 65 Coresta units.

When all the paper grades with the characteristics described in the examples provided were used in cigarette production, satisfactory ash formation was observed when smoking the cigarettes, there was only a very slight off-taste, or none at all, and the paper wrappers had a high-quality, uniform appearance.

In the experimental descriptions, all cigarettes made using the paper presented in the invention did not have ventilation channels.
