Abstract
A ventilated filter cigarette has a multiple filter with a higher global retention provided in different sections with ventilation perforations. The ventilated filter cigarette contains a tobacco mixture of expanded tobacco having a high nicotine content. The tobacco mixture contains as constitutive element expanded tobacco lamina with a nicotine content 1.0 % to 8 % and/or tobacco foil with a nicotine content 5 % to 10 %, to which fruit acid is incorporated. The tobacco mixture has a nicotine content 2.5 % to 5 %. The resistance to draw of the multiple filter is higher at the tow side than at the mouth side, and the degree of ventilation lies in a range 50 % to 95 % added air. The main smoke flow preferably has an 'American blend' taste with an approximately constant taste per puff. The pH value of the smoke lies in a range 6.0 to 7.5. While giving good sensory results, the cigarettes have condensate and nicotine values respectively of less than 1 mg per cigarette and 0.1 mg per cigarette and in special cases of less than 3 mg per cigarette and less than 0.6 mg per cigarette.
Description
The present invention relates to according to the described a kind of ventilation of preorder of claim 1 cigarette with filter tip.
German patent DE-OS 3228950 disclosed a kind of cigarette with filter tip of ventilation, contained (being expanded) tobacco mixture of pro rata volume activation, and its nicotine content is 2-5%.This cigarette has inefficient filter tip, and its filter efficiency is up to 35%.According to example, the coagulation value is between 7 to 17 milligrams " tar " (being coagulation).
German patent DE-OS 3638801 disclosed a kind of ventilation cigarette with filter tip, the jealous of its each suction is constant basically.This is owing to added a kind of special filter material and just be achieved, and this filter material is along with the continuous increase of steam content in the main flume permeability to aeration air also constantly increases.
A kind of method of adding nicotine and levulic acid or nicotine levulinate in cigarette cut tobacco is disclosed in patent EP-A2-O 283672.The ventilation made from this pipe tobacco the coagulation value of cigarette with filter tip should be below 7 milligrams " tar ".
In addition, in the moment of the present patent application patent, the cigarette with filter tip of the known ventilation that promptly on market, can buy, its coagulation (K) value and nicotine (N) value are equal to or less than 1 milligram of K and 0.1 milligram of N respectively.For instance, the cigarette NOW that U.S. RJ Reynolds Tobacco Holdings ,Inc. (Fa.Reynolds/USA) produces, its coagulation value is≤0.5 milligram; The extremely light type cigarette of youngster (DUNHILL ULTIMATE LIGHTS) is deceived in working as that Luo Fumen company (Fa.Rothmans) produces in addition, and given value is " being lower than 1 milligram of tar, 0.1 milligram of nicotine ".This cigarette still is worth improving on jealous through the most consumers comment, and this point can be inferred by the market occupancy volume of this cigarette is smaller on the one hand, also can confirm by its inner smoker's test on the other hand.
Task of the present invention provides a kind of super light type cigarette with filter tip, and with regard to known state of the art, this cigarette can guarantee to reach: every suction once all keeps almost constant high-quality jealous, and total coagulation value and nicotine value are all very low; The undesirable flue gas inclusion of people is lowered to minimum degree in main flume and time stream flue gas simultaneously, adopts the common low raw material of cost, does not especially need complicated filter tip manufacturing process.
The solution of above-mentioned task can realize by the various features described in the major event claim according to the present invention, proposes some preferred embodiments in this respect especially in the subordinate item claim.
By according to combination of the present invention, for example the gas phase and the particle inclusion of undesirable all flue gases can be reduced to minimum degree, for spices and the fragrance that the smoker liked comprises that the nicotine order is surprisingly still in store, make slight smoker satisfied fully simultaneously.For reaching effect unexpected concerning the professional-objectively: the size of several values is K≤1 milligram/N≤0.1 milligram, subjective: be entirely satisfactory to beg flavor-following point be contributive: do not expected and ground just can guarantee that from inhaling first mouthful of cigarette almost constant " jealous coagulation " measure, as shown in Figure 1.Draw among the figure and whenever have a suck of the curve of the given coagulation amount of cigarette the suction number of times.The super light type cigarette that this situation is traditional just is unexistent, thereby impels them not received by people.
Should assert, above-mentioned amazing effect partly obtains by following measure: at first adopt the highly bulked pipe tobacco that makes meticulously according to so-called INCOM-method (according to applicant's patent documentation DE 2,903 300, DE 31 19 330 and the expanded method of DE 34 14 625), in conjunction with the general filter tip with certain filtering ability originally.As shown in Figure 1, the result who obtains by this measure is that whenever to have a suck of the given coagulation of cigarette almost be constant.
The outstanding feature that adopts the expanded pipe tobacco of INCOM method is the honeycomb that obtains the fiber pipe tobacco.This point does not reach such degree by other known method.Those honeycombs according to the expanded pipe tobacco of method for distinguishing can suffer damage significantly, and are associated therewith, and a large amount of losses can appear in a part of fragrance and nicotine, for adopting the expanded pipe tobacco of INCOM method then this situation can not occur.There, important fragrance, nicotine and association alkaloid may all be " released ", and that is to say, even they may easily be taken away by very little air capacity or mainstream smoke amount especially.
Can estimate,, only need atomic little air capacity just can bring into play valuably especially through this more effective fragrance and the nicotine flowability of the expanded pipe tobacco of INCOM method.This air capacity is to be sucked into by burning red cigarette cone head part on the cigarette according to height ventilation of the present invention.Can assert equally, obviously being different from tow delay effect common cigarette, especially little is because following former therefore event: the tow according to cigarette of the present invention is still always stiffening, the tendency of not caving in, the packed density of its pipe tobacco low and inhale anti-less, thereby help super light type cigarette to keep very high jealous.
In a word, why can obtain under the situation of minimum that this is very high jealous, be owing to used the multi-filtering mouth portion that partly shows the high overall filtering power of the present invention.Filter-tip filtering usefulness or efficient are by in total amount of retaining in the filter tip (coagulation and nicotine)-for the amount that flows into-decide.This multi-filtering mouth, also be multistage filtering mouth or combination filter tip, at least comprising two filter tip part or filter tip sections different or that have spacing ground (cavity filter tip) to arrange constitutes, they are made by different each other different filtering materials, therefore can distinguish forcefully different inclusion in the filtering cigarette, and can also be whereby go up from " taste " coordinated with each other, especially combine with this taste on advantageous effects suitable ventilation.
In general, people are when inhaling the filter-tip super light type cigarette of the sort of non-ventilation with high filtering power, always feel to have a kind of unacceptable high suction to resist, inhale of the same type when having the filter-tip cigarette of high ventilation, to inhaling anti-still acceptable, but often just obtain the sensation of " hot-air ", that is to say, feel seldom jealous in the main flume.This result has avoided on according to cigarette of the present invention unexpectedly.
Compare traditional cigarette, the pipe tobacco weight used according to cigarette of the present invention is much lower, and its result makes time stream cigarette significantly reduce very naturally.This desirable effect that conforms with can strengthen by following measure: that use can be buied or certain can reduce time the cigarette paper of stream cigarette-for example use patent document DE 3,802 645 and the described cigarette paper of DE3802646 according to the applicant, also the size of cigarette profile correspondingly can be dwindled.Therefore, in a certain embodiments, provide a kind of article of inhaling, this article are considerably less based on its main flume emitting substance and time stream flue gas emitting substance, under the condition that keeps " classics " cigarette resemblance, fully can compare favourably, and not need with expensive raw material and complicated manufacturing process with a kind of known " smokeless cigarette substitute ".
Tobacco mixture is preferably done as a wholely to handle according to bloatedization method or expanded method.Like this, the volume of tobacco mixture has increased, and result's (for initial volume) makes " fillable " corresponding raising of tobacco mixture.Certainly, in this case just with blade pipe tobacco part or the pipe tobacco that contains damaged fibers element not expanded or volume activation processing in addition, remaining pipe tobacco thin slice (if blending) then so not by expanding treatment.By blade pipe tobacco that can be expanded and the laminar whole mixture of pipe tobacco that can not be expanded, through (calculating) when expanded, the pipe tobacco of cutting the very carefully part that those closely mix each other jointly stands a kind of mechanical treatment and a kind of heat treatment.Can estimate, help like this nicotine from the pipe tobacco thin slice to the blade pipe tobacco, in other words, the migration from the high lobate pipe tobacco of nicotine content to the time that depends on of the low blade pipe tobacco of nicotine content, thus can realize that nicotine distributes more uniformly in the tobacco mixture.This measure no doubt makes cost to increase to some extent, but in smoking process, keep main flume to stablize constant taste effect favourable.But, also can be only with the part of tobacco mixture for example only with the blade pipe tobacco in addition expanded method handle, and that the not expanded a part of pipe tobacco that uses in the tobacco mixture can be by being traditional or " technology " pipe tobacco is formed as the band muscle pipe tobacco that chops up originally.This band muscle pipe tobacco for example has and helps from the reactivity of taste adjusted according to cigarette of the present invention.Similarly, add original known condiment and spices, this is also helpful for obtaining desirable total taste sense.At last, can be before or after bloatedization method or expanded method are handled add to condiment or spices in the whole tobacco mixture or add in some part of this mixture.After this tobacco mixture that is mixed with can process on general cigarette machine by known method, comprises connecting on cigarette with filter tip according to the present invention according to the multi-filtering mouth described in the claim.
In a embodiment, under all identical in addition creating conditions, abandon fully using the pipe tobacco thin slice, so that whole cigarette cut tobacco final mixture can the volume activation about tobacco mixture.So just, can use to contain the pure pipe tobacco of nicotine, under specific circumstances even can use and contain the pipe tobacco of nicotine up to 8% (weight) up to 6% (weight).
Now the present invention is done more detailed explanation with regard to following embodiment:
Example A
Composition with a kind of tobacco mixture of U.S.'s mixed characteristic is:
The 33% tobacco curing silk that dries in the air
28% baking pipe tobacco
14% east pipe tobacco
25% pipe tobacco thin slice
Its average nicotine content is 3.4%.This tobacco mixture integrally (is mixed the back) and is carried out the volume activation processing according to the INCOM method, it is about 60% that its fillable improves, the tow that is made into (7.9 millimeters of diameters, long 59 millimeters), the pipe tobacco operating weight is 460 milligrams, and its gross weight comprises that cigarette paper is 500 milligrams.The packed density of this tow is 160 milligrams/centimetre
3, cigarette hardness (measuring by DE-OS 39 29 155 described methods) is 2.25 millimeters depths of cup.The venting quality of cigarette paper is 40CORESTA.
This tow has double filtration mouth (paper/acetate fiber), and uses non-porous covering paper, makes cigarette with filter tip according to a conventional method.About paper, refer to a kind of commercial universal fibre cellulose fiber net filter tip here; About acetate fiber, refer to a kind of traditional cellulose-acetate fiber filter tip here.The suction of the paper-filter segment of tow one side of 12 millimeters long is anti-to be 175dapa; The suction of long 13 millimeters filter tip side cellulose acetate filter sections is anti-to be 15dapa.Filter tip ventilation by a kind of laser boring method realizes according to Deutsche industry norm (DIN) DIN 6565, draws 77% additive air venting quality.
The cigarette data of cigarette A1 (measuring according to DIN-ISO 3402/87/10315/10362-1) are concentrated and are listed in the table 1.The detected pH value that also has cigarette, this is the 32nd tobacco chemistry seminar (32 in 1978 according to Harris people such as (Harris)
NdTob.Chem.Res.Confl., the method for being introduced 1978) detects.
Table 1 is listed the corresponding value of cigarette A2 and A3 in addition, and these two kinds of cigarettes only are having any different of its tobacco filters and cigarette A1.In these cases, also used a kind of paper/acetate fiber-double filtration mouth, the paper filter tip section of its tow one side is 12 millimeters long, and the cellulose acetate filter section of mouth side is 13 millimeters long, but its suction is anti-different, and the value of venting quality is also inequality.
Table 1: filter tip data and cigarette data cigarette A1 A2 A3 according to the described cigarette of example A inhale anti-175 94 175
Paper-filter tip section (daPa) inhales anti-15 50 50
The pH-value 7.0 of acetate fiber-filter tip section (daPa) venting quality (% additive air) 77 84 78 suction number of times 5.7 6.0 5.5 coagulations (K) (milligram) 0.2 0.2 0.1 nicotines (N) (milligram) 0.05 0.04 0.02K/N 455 cigarettes--
The sensibility qualification result of all these three kinds of cigarettes compares with the traditional super light type cigarette of its K-value 〉=1 milligram, and is identical at least, even better.
Example B
Composition with a kind of pipe tobacco complex of U.S.'s mixed characteristic is:
The 40% tobacco curing silk that dries in the air
20% baking pipe tobacco
15% east pipe tobacco
25% pipe tobacco thin slice
Its average nicotine content is 3.6%, whole tobacco mixture (mix back) press the INCOM method in addition volume activate, the fillable of its tool improves about 55%; The pipe tobacco weight that the tow of making (7.9 millimeters of diameters, long 59 millimeters) uses is 450 milligrams, and gross weight comprises that cigarette paper is 490 milligrams.The packed density of this tow is 155 milligrams/centimetre
3, cigarette hardness (method according to DE-OS 39 29 155 is measured) is 2.4 millimeters impression solubility.The air permeability of cigarette paper is 40CORESTA.
This tow is furnished with double filtration mouth (paper/acetate fiber), and use non-porous clad can paper) make the cigarette with filter tip of laser boring according to a conventional method, certainly, as shown in example A, the length of the paper filter tip section of its tow one side also is 12 millimeters, and the length of the cellulose acetate filter section of mouth side also is 13 millimeters.
Always list the not cigarette data of B3 of three kinds of cigarette B1, B2 in the table 2, these three kinds of cigarettes are because the suction of filter tip section is anti-different and different with venting quality.Table 2: inhale drag 175 94 94 according to the filter tip data of the described cigarette of example B and the data cigarette B1 B2 B3 of cigarette
Paper-filter tip section (daPa) inhales anti-15 50 50
Acetate fiber-filter tip section, (daPa) venting quality, (% additive air) 77 84 88 suction number of times 5.2 5.8 6.0 coagulations, (K), (milligram) 0.2 0.3 0.1 nicotines, (N), (milligram) 0.04 0.04 0.01K/N 5 7.5 10
The sensibility qualification result of these three kinds of cigarettes contrasts the super light type cigarette of its traditional K-value 〉=1 milligram, about equally.But, seem than one of common traditional super light type cigarette taste heavier (reactivity is bigger) according to the described several cigarettes of example B.
Example C
A kind of tobacco mixture with U.S.'s mixed characteristic, its pure composition is:
The 50% tobacco curing silk that dries in the air
35% baking pipe tobacco
15% east pipe tobacco
Its average nicotine content is 3.5%, and whole tobacco mixture (mixed back) is pressed in addition volume activation processing of INCOM method, and its tool fillable improves about 60%.The tow that mixture is made into (7.9 millimeters of diameters, long 59 millimeters), used pipe tobacco weight is 420 milligrams, gross weight comprises that cigarette paper is 460 milligrams.The packed density of this tow is 145 milligrams/centimetre
3, cigarette hardness (method according to DE-OS 39 29 155 is measured) is 2.4 millimeters depths of cup.The air permeability of cigarette paper is 40 CORESTA.
This tow is furnished with double filtration mouth (paper/acetate fiber), and uses non-porous covering paper, makes the cigarette with filter tip of laser boring according to a conventional method.Certainly, described similar to example A, the length of the paper filter tip section of its tow side is 12 millimeters, and the length of the cellulose acetate filter of mouth side is 13 millimeters.
Always list cigarette data in the table 3 according to the described cigarette of example C.Table 3: filter tip data and cigarette data cigarette C according to the described cigarette of example C inhale drag 95
Paper-filter tip section (daPa) inhales anti-15
Acetate fiber-filter tip section (daPa) venting quality (% additive air) 62 suction number of times 5.1 coagulations (K) (milligram) 1.40 nicotines (N) (milligram) 0.20K/N 7
Contrast traditional light type cigarette that the K value is 4 to 7 milligrams and corresponding nicotine value that has, the sensibility qualification result of listed this cigarette equates with it surprisingly substantially in the table.But, the cigarette according to example C seems really that than some traditional light type cigarette strong (reactivity is bigger) more arranged.
