Definitions
- the present invention relates to a cigarette paper which imparts a uniform tensile profile to a cigarette made therefrom. It further relates to a method for producing such a cigarette paper, a cigarette and the use of a location-dependent concentration of a fire salt in a cigarette.
- a typical cigarette is made of tobacco which is wrapped by the cigarette paper and together forms a typically cylindrical tobacco rod.
- the tobacco rod is followed by the filter, which typically consists of cellulose acetate fibers.
- the filter and tobacco rod are wrapped by the tipping paper.
- the tipping paper connects the filter to the tobacco rod.
- the cigarette paper has in addition to the function of wrapping the tobacco, among other things, the task of the cigarette to give an attractive appearance in the smoked and not hacked state and to influence the smoldering speed of the cigarette. It also serves to control the composition of the smoke, especially the content of tar, nicotine and carbon monoxide.
- the smoker When smoking, the smoker creates a negative pressure at the mouth end of the smoldering cigarette, is sucked through the air on the one hand by the cone of embers on the cigarette holder, but on the other hand also flows through the air-permeable cigarette paper into the tobacco rod and so diluted the smoke.
- the stream of air flowing through the air-permeable cigarette paper into the tobacco rod during smoking is called strand ventilation.
- the tipping paper In the case where the tipping paper is perforated, air flows through the tipping paper into the filter and also dilutes the smoke. This air flow is called filter ventilation.
- the total dilution of the smoke is composed of the strand ventilation and the filter ventilation.
- the tobacco cord burns, so that its length decreases.
- the available area for the strand ventilation cigarette paper decreases, so that less and less air can flow through the cigarette paper in the tobacco rod and thus the strand ventilation decreases from train to train.
- the smoke is less dilute from train to train, and the concentration of the smoke-forming aerosols and gases in the smoke flowing from the mouth end increases.
- the tobacco rod has a certain filtration effect on the smoke, which is also decreasing with decreasing length of the tobacco rod. This gives the smoker the impression that the cigarette is getting "stronger" from train to train.
- the cigarette paper may be perforated with the portion of the cigarette paper close to the filter being more perforated and thus having a higher air permeability than the rest of the cigarette paper.
- the strand ventilation does not decrease as much as with cigarette paper with an approximately constant air permeability along the tobacco rod.
- this method sometimes has the disadvantage that such cigarettes are difficult to ignite because much air flows through the more perforated part of the cigarette paper and the air flow through the tip of the cigarette is too low to start the glowing process when lighting.
- the cigarette paper is equipped with burn salts and designed so that the content of one or more Brandsalze in the cigarette paper from the filter end to the tobacco end changed on a cigarette made from it, in particular, that it changes monotonously within normal production and measurement tolerances, ie either monotonous increases or decreases monotonically.
- the change need not be strictly monotone, so there may be portions of constant content of the one or more Brandsalzes.
- the variable content or the variable concentration of Brandsalzen is chosen so that the cigarette paper gives a cigarette made therefrom, in particular a filter cigarette, a more uniform tensile profile, than in an otherwise similar cigarette with a constant along the longitudinal direction of the Brandsalzkonzentration would.
- the burn salts are substances, for example salts, which can increase or decrease the smoldering speed of the cigarette paper.
- Very commonly used are trisodium and tripotassium citrate and mixtures thereof.
- Trisodium and tripotassium citrate are erfmdungssiee examples of the glow-accelerating, ie fire-promoting, Brandsalze, while phosphates can serve as an example of the invention for the slowing-slowing, so fire-retardant, Brandsalze.
- a fire salt is fire-promoting or fire-retardant is generally known to those skilled in the art, or it can be easily determined by measuring the smoldering speed of a cigarette paper containing the fire salt in question in sufficient quantity.
- the direction x of the cigarette papers may or may not necessarily be in accordance with the machine direction.
- the length L corresponds to the length of the visible tobacco rod on the cigarette for which the cigarette paper is intended, d. H. the length from the point where the tobacco rod emerges from under the tipping paper to the tip of the cigarette to be lit. This length L may be different for different types of cigarettes, but will typically be ⁇ 11 cm and> 3 cm.
- the function f (x) is monotone over the interval [0, L], but does not necessarily have to be strictly monotone. On the contrary, some of the presently preferred embodiments have near-end and near-tip portions having a uniform or substantially uniform concentration c (x) of the burnt salt. In any case, the function f (x) is not constant over the entire interval.
- the actual concentration c (x) of the fire salt may deviate from the monotone function f (x) by an amount of Ac.
- This value Ac takes into account the usual production and measuring tolerances of the Brandsalzgehaltes.
- Ac defines a certain corridor about an idealized f (x) that still allows for an improvement over a constant Br, but possibly deviates locally moderately from the ideal monotonicity. Since the influence of Brandsalzen on the Abrauchowski is comparatively complex and not completely understood, the expert will determine the most suitable variation of the Brandsalzgehaltes experimentally in many cases. However, extensive research by the inventors has shown that, in fact, in many cases, the above-described monotonic or nearly monotonous course of the fire salt concentration will give good results.
- the minimum for tar and nicotine is typically at a fire salt content between 1.5% and 5.0% by weight, for trisodium citrate typically at a fire salt content of 1.5% to 3% , 0 wt .-% and for tripotassium citrate at 3.5 wt .-% to 5.0 wt .-%, each based on the mass of the cigarette paper, as it is used on the cigarette.
- the levels of smoke are beginning to rise again.
- a first possibility is to choose the content of the Brandsalzes at the filter end of the cigarette near the value at which - with an otherwise equal cigarette but with constant Brandsalzgehalt - a minimum tar and nicotine would be achieved and the content of the Brandsalzes then in the direction of to be lit end of the cigarette monotonically or at least approximately monotonically.
- a second possibility is to choose the content of the Brandsalzes at the filter end of the cigarette again close to the value at which a minimum tar and nicotine is achieved, but then to increase the content of the Brandsalzes in the direction of the end of the cigarette to be ignited.
- the Brandsalzgehalt which - with constant Brandsalzgehalt - to minimal tar and nicotine values leads near the filter end of the tobacco rod, ie in an area of the cigarette that produces the "strongest” features when smoking, while those Brandsalzgehalte, the - At constant Brandsalzgehalt - to higher Abrauch tone drove near the end of the cigarette to be ignited, ie where the trains are rather "weak".
- a "strong” or “weak” train is understood to mean that the levels of exhaustion of tar and nicotine are higher or lower this turn relative to the other strokes on the same cigarette.
- f (x) For the monotone function f (x), preferably
- L corresponds to the length of tobacco rod visible on the associated cigarette, ie, the length from the point where the tobacco rod emerges from under the tipping paper to the tip of the cigarette to be lit.
- the cigarette paper is therefore preferably designed so that for at least one fire salt with the content c (x) at the position x the inequalities
- the values Li and L 2 should be set so that the rise or fall is neither too steep nor too late to begin or end.
- the upper limit for Li 2L / 3, preferably L / 2 and more preferably L / 3 has proven.
- the lower limit for Li is 0, and preferably L / 6.
- the upper limit for L 2 can usually be set at L, preferably at 5 L / 6. In general, however, it must always be true that Li is less than or equal to L 2 . , ,
- a preferred upper limit for the length of the increase or decrease, L 2 -L], is therefore 9L / 10 and more preferably 4L / 5 and most preferably 2L / 3.
- the values for c 0 or CL should be greater than or equal to 0% by weight, preferably greater than 0.2% by weight and particularly preferably greater than 0.5% by weight. With regard to the upper limits for c 0 and CL, 15% by weight is a possible choice, but 10% by weight and more preferably 7% by weight are preferred.
- the at least one fire salt the content of which changes on the cigarette paper, is a citrate
- 5% by weight has also proved to be a very particularly preferred upper limit.
- These ranges apply to c 0 and CL independently. However, it must always be true that c 0 is different from CL, ie in fact there is a change in the fire salt content, and preferably the amount of the difference C 0 -CL is greater than 2Ac.
- the value for Ac preferably corresponds to the abovementioned values.
- Acetates, citrates or phosphates in cigarette paper can be found, for example, in CORESTA Recommended Methods 33, 34 and 45.
- the cigarette paper is designed so that it can produce cigarettes, which have within the production and measurement tolerances the nominally same course of the content of at least one Brandsalzes along the visible tobacco rod.
- the cigarette paper is provided with one or more markings which allow the cut of the tobacco rod to be synchronized with the course of the fire salt content, whose positions are thus in a predetermined local relation to the curve c (x) of the fire salt content.
- the markings are preferably detectable by their action on electromagnetic waves, that is, for example, transmission, reflection, refraction or absorption of visible light, ultraviolet light or infrared radiation, and more preferably by an optical sensor, in particular an optical sensor which responds to reflected visible light to be detected.
- these markers are mounted on the cigarette paper so that they come to lie on the finished cigarette under the tipping paper and thus are not visible to the smoker.
- One possible method is to slightly color the composition with the one or more branding salts applied to the paper and to apply a fine but easily detectable line or other mark at the location where the tipping paper overlaps with the cigarette paper , Preferably, one will imprint the line or marking on the later side facing away from the tobacco, so that after production of the tobacco rod, the line or mark remains detectable for an optical sensor. Generally that's the top of the cigarette paper. It is also possible to place the line or mark on the tobacco-facing side of the cigarette paper, but then it is advisable to detect the line or mark on the cigarette paper before the tobacco rod is formed on the cigarette machine.
- the invention can also be applied to cigarettes which contain no filter.
- base cigarette paper d. H. of the starting cigarette paper which is to receive the location-dependent Brandsalzkonzentration invention
- Base cigarette papers preferred for the invention consist of pulp fibers derived from wood, flax, hemp, esparto grass or other materials. Mixtures of pulp fibers of various origins can also be used. Preferred base cigarette papers have a basis weight of 10 g / m 2 to 60 g / m 2 , with the range of 20 g / m 2 to 35 g / m 2 being particularly preferred.
- the preferred base cigarette paper also contains inorganic mineral fillers which are added to the paper in a mass fraction of 10% to 45%.
- a particularly preferred filler is lime (calcium carbonate), but other oxides such as magnesium oxide and aluminum hydroxide and carbonates and mixtures thereof can also be used.
- Precipitated lime is preferred over geologically degraded lime for its purity and more uniform particle size.
- Cigarette papers without filler or with less than 10%) filler are also common and conceivable for the invention, especially for non-machine-made cigarettes ("roll-your-own", "make-your-own”).
- cigarette papers are known with more than 45% filler, but with increasing filler content, the strength of the paper decreases, and the paper tends to release dust in further processing, which is why this design is not preferred for use in machine-made cigarettes.
- An important factor for the characterization of the cigarette paper is its air permeability. It is measured in accordance with ISO 2965 and expressed in cm.mkf'.kPa "1.
- the preferred base cigarette papers in the context of the invention have a natural air permeability, ie without further perforation, of 0 cm min -1 kPa -1 to 350 cm min "1 kPa " 1 , preferably between 20 cm min "1 kPa “ 1 and 200 cm min "1 kPa “ 1 and more preferably between 30 cm min '1 kPa "1 and 120 cm min " kPa " .
- the air permeability can be significantly increased, for example, over 300 cm min "1 kPa " 1 or even over 1000 cm min "1 kPa " 1 .
- Cigarette papers are typically made in rolls of, for example, between 0.3m and 5m widths and cut into reels having a cigarette circumference derived width, typically 9mm to 35mm, or an integer multiple of that width.
- the known from the prior art treatment of the cigarette paper with Brandsalzen comprises impregnation of the paper on the paper machine in the size or film press with a water-based solution of the Brandsalzes and subsequent drying. Also a soaking of the paper on a separate downstream of the paper machine device is conceivable.
- aqueous composition with a particularly high Brandsalzkonzentration is applied over the entire surface and uniformly on the overdried paper by means of a flexographic printing unit integrated in the paper machines and the paper is then rolled directly without further drying.
- the at least one fire salt is applied to the base cigarette paper in the form of a liquid composition, especially a solution, suspension or other form of mixture in a solvent.
- a liquid composition especially a solution, suspension or other form of mixture in a solvent.
- This order can preferably be achieved by a printing process or by spraying.
- the single-layer application is preferred over a multilayer.
- the printing process can be formed by gravure printing or flexographic printing.
- a gravure cylinder is preferably provided with wells, from which the composition to be printed is transferred to the base cigarette paper, wherein the volume of the wells and / or the density of the wells on the gravure cylinder, which is also referred to as "grid size of the wells" can, is or is chosen so that the desired location-dependent concentration c (x) of the Brandsalzes results.
- this process is used to modify a possibly even constant course of the content of at least one fire salt which is already present in the cigarette paper.
- processing steps such as printing on prior art tapes to achieve self-extinguishment, may be before, after, or - - be carried out simultaneously with such treatment of the paper to produce or modify a course in Brandsalzgehalt.
- the composition used to prepare the history of the fire salt content comprises at least one fire salt and a solvent.
- solvent should not be considered as limited to solutions in the chemical sense.
- the fire salt may also be in suspension in a suspension or other form of the mixture in the solvent.
- water is preferred as a solvent over organic solvents because it leaves no trace of the taste of the cigarette in the paper and is safe in terms of fire hazard.
- the content of the Brandsalzes in the composition is at least 0.1 wt .-%, preferably at least 1 wt .-% and particularly preferably at least 2 wt .-%, and at most 15 wt .-%, preferably at most 10 wt .-% and particularly preferably 7% by weight, where the statements are to be understood as the mass of the anhydrous Brandsalzes based on the mass of the finished composition.
- the composition for example, for adjusting the viscosity, other substances, in particular polymers individually or in any mixture, included.
- polymers are cellulose derivatives, such as carboxymethyl cellulose, polysaccharides, such as starch or starch derivatives, or in particular also alginates, dextrins, guar or gum arabic.
- Such substances may be required, for example, for chromium-plated steel printing cylinders for intaglio printing in order to produce a film on the printing cylinder by the adapted viscosity so that the doctor applied to the printing cylinder does not scratch the printing cylinder.
- such substances may possibly be omitted in the composition.
- the viscosity of the composition can be characterized by the flow time, and it will, for example, for the gravure between 10 s and 40 s, preferably choose between 12 s and 35 s, measured as flow time from a cup with an opening of 4 mm according to ⁇ NORM EN ISO 2431: 2011.
- the measurement of the flow time should be carried out at the temperature at which the composition is used in the application process.
- the applied amount of the composition on the initial basis weight of the cigarette paper ie on the basis weight before the application of the composition must be coordinated.
- the applied amount of the composition should be at most 100% of the starting surface weight, preferably at most 80%, and more preferably at most 60%.
- the upper limits result from the amount of composition which can be applied to a cigarette paper without significantly impairing its processability, for example due to the reduced strength in the wet state.
- a lower limit results from the possibilities of the application method and is at least 0% of the starting surface weight, preferably at least 0.5% and particularly preferably at least 1%. Surfaces to which no order of the composition is made, of course, can also be provided.
- any type of dryer can be used, for example hot air dryer, infrared dryer, tunnel dryer, heated drying cylinder or even a drying by microwaves.
- the drying of the cigarette paper after the application of a water-based composition is preferably carried out by contact with one or more heated drying cylinders. Treating the paper with waterborne compositions often results in the formation of wrinkles in the paper that can be efficiently reduced by drying with drying cylinders.
- one or more spreader rollers or smoothing devices can be provided which pull wrinkles from the paper during drying and are preferably arranged so that the paper passes over one or more spreader rollers or the smoothing devices prior to contact with the first drying cylinder.
- the spreader rollers or smoothing devices may also be arranged after one or more drying cylinders.
- these technologies can also be used, but the problem of wrinkling does not occur there or only to a considerably lesser extent.
- the subject invention depends in the circumferential direction only on the average content of the at least one Brandsalzes, which is why preferably the content of the at least one Brandsalzes in the cigarette paper in the transverse direction, i. is substantially constant in the circumferential direction on a cigarette made from the paper according to the invention. This prevents the cigarette from smoldering unevenly around its circumference, and ash or tobacco falling out or the ash image being deteriorated.
- FIG. 1 shows a cigarette and, arranged above it in a diagram, shows an exemplary course of the content of the at least one fire salt.
- FIG. 2 shows an exemplary course of the content of the at least one
- an aqueous solution was prepared from the brine salt, as prepared for the prior art infusion of the paper.
- the content of Brandsalz in the solution resulted from the desired course of the content in the cigarette paper and the specifications of the application process.
- the application of the burn salts was carried out by gravure printing with an engraving of the gravure cylinder corresponding to the geometry of the desired course.
- the content of tar and nicotine in each train was calculated as the mean (M) in mg over all trains, the coefficient of variation (CoV) in% across all trains and the ratio V of the content between last and first train.
- the coefficient of variation is the standard deviation of the respective smoking value over all the traits of a cigarette divided by its mean and expressed as a percentage.
- Brandsalzgehalts according to the function f (x) are characterized by the parameters c 0 , CL, LI and L 2 and shown together with the results in Table 1.
- the course no. 1 corresponds to a constant Brandsalzgehalt of 1.4% and served as a comparison.
- V On the basis of the ratio V, a clear increase in the tar content of 62% and in the nicotine content of 41% can be seen.
- the coefficients of variation of tar and nicotine are 16.1% and 11, 6%.
- the courses 2 to 6 show a sinking from the mouth end to the cigarette tip content of fire salt, while the courses 7 to 13 correspond to an increasing content of fire salt.
- the courses 12 and 13 is still in addition to a length of 10 mm and 5 mm respectively at the mouth end and the cigarette holder, the content of Brandsalz constant and in between linearly increasing.
- the Brandsalzgehalt in the region of the filter end are at least approximately selected so that it - in a per se same cigarette with constant Brandsalzgehalt - leads to a minimization of a certain Abrauch learners, in particular nicotine or tar, and starting from this value in the direction the - -
- Cigarette tip monotonically or approximately monotonically increases or decreases.
- the term “approximately chosen so” should allow deviations from the ideal value of the Brandsalzkonzentration that less than 50%, preferably less than 30%, more preferably less than 15% of the ideal value be [EBI]
- the same cigarette is also meant a cigarette made from the same base cigarette paper or a base cigarette paper in which the weight per area is not more than 20% and whose mean air permeability is ISO 2965 not more than 15%
- An exemplary cigarette 100 consists of a filter 101 encased in a tipping paper 102 which partially overlaps the tobacco rod 103, which in turn is enveloped by a cigarette paper 104. On the cigarette 100, the tipping paper 102 is then in the overlap zone over the cigarette paper 104.
- the diagram 110 arranged above the cigarette 100 in FIG. 1 shows an exemplary profile of the content of the at least one fire salt.
- this is an idealized course, of which in reality deviations, for example, by the usual production tolerances and inhomogeneities of the paper possible are.
- an endless tobacco rod is formed which is cut into pieces having the length of the tobacco rod on the cigarette. Between each pair of such pieces, a double-length filter plug is inserted and glued to a doubly wide mouthpiece covering paper to form a double cigarette connected to the filter end. In a final cut, the double cigarette is divided into two cigarettes and turned over one of the two cigarettes, so that all running out of the cigarette machine cigarettes are the same orientation. This results in the need to choose the course of the content of at least one Brandsalzes along the cigarette paper web accordingly. Such an exemplary course is shown in FIG.
- the main direction of the cigarette paper is indicated by the arrow 201.
- the content of the at least one Brandsalzes is plotted and its course in the direction 201 is represented by the line 203.
- a piece of tobacco rod is made by cutting at each of the positions indicated by lines 204 and 205.
- the demarcated by the dashed lines 206 area 207 comes to rest on the double cigarette under the tipping paper and is thus not visible in normal use. In this area 207, the course of the content of at least one Brandsalzes plays no role, because this area is not usually smoked.
- the skilled person will be able to find a course of the invention content of at least one Brandsalzes with little experimental effort for a large class of Brandsalzen, so that the invention can be easily transferred to a variety of Brandsalze. Likewise, he will be able to find a desired course of the content of at least one Brandsalzes for different cigarette papers and cigarette designs.
