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 from 1.0 % to 8 % and/or tobacco foil with a nicotine content from 5 % to 10 %, to which fruit acid is incorporated. The tobacco mixture has a nicotine content from 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 from 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 from 6.0 to 7.5. While giving good sensory results, the cigarettes have condensate and nicotine values respectively of less than 1 mg/cigarette and 0.1 mg/cigarette and in special cases of less than 3 mg/cigarette and less than 0.6 mg/cigarette.

Description

Vented Filtered Cigarette {VENTILATED FILTER CIGARETTE}

German Publication No. 3,228,950 shows a ventilated filter cigarette with a balanced volume-activated (ie inflated) tobacco mixture having a nicotine content of 2 to 5%. This cigarette has a low efficiency filter with a filter efficiency of up to 35%. The condensate value according to embodiments of the publication is "tar", ie 7 to 17 mg of condensate.

German Publication No. 3,638,801 discloses a vented filtered cigarette with an essentially uniform taste at each pull. This is achieved by using a special filter material that allows the mainstream smoke to have more permeate through the vented air while having an increased water vapor content.

EF-A2-0,283,672 shows doping of cigarette tobacco with nicotine and levulinic acid or nicotine levulate. The condensate value of the vented filtered cigarette thus produced is such that the "tar" is 7 mg or less.

In addition, ventilated, filtered cigarettes having a condensate value (K) and nicotine value (N) of approximately 1 mg K and 0.1 mg N or less, respectively, are known or currently available. For example, NOW cigarettes from Reynolds, USA, with a condensate value of 0.5 mg or less, and DUNHILL ULTIMATE LIGHTS cigarettes from Rothmans, with values labeled "1 mg tar and 0.1 mg nicotine" have. However, most types of consumers believe that these types of cigarettes need to be improved in terms of taste, which on the one hand can be deduced from the relatively small market share of these types of cigarettes, on the other hand. Is confirmed by the in-house smoker test.

The present invention relates to a ventilated filter cigarette according to the preamble of claim 1.

1 is a graph showing the amount of condensate obtained at each pull compared to the number of suctions.

The object of the present invention, compared to the known state of the art, is to have a very low condensate value and nicotine value, in particular with the use of conventional cost effective raw materials, without the need for particularly complicated filter techniques. Extremely light, ensuring that all undesirable smoke components of both smoke and stream smoke are simultaneously reduced to a minimum, while maintaining a substantially high quality flavor yield at each suction. ) To provide a cigarette with a filter.

The solution for achieving this object is achieved according to the invention by the features described in the independent claims of the claims, in particular the preferred embodiments mentioned in the dependent claims.

As a result of the combination of features according to the invention, all undesirable smoke constituents, for example in the gas phase and in the particles, can be reduced to a minimum, and taste components and flavors, including nicotine, which the smoker desires. The ingredients can be obtained in a very surprising way, to the extent that they fully satisfy weak smokers. Such effects that would not be expected for those skilled in the art (objectively, for example, a value level of K ≦ 1 mg / N ≦ 0.1 mg and, subjectively, a completely satisfying flavor volume) The cause of)) may be that, in a surprising manner, an approximately constant amount of "taste condensate" is obtained from the first suction, as shown in Figure 1 of the accompanying drawings. The amount of condensate obtained is plotted against the number of aspirations. This fact is lacking in conventional extremely mild cigarettes, and can contribute to disallowing such conventional cigarettes to the consumer.

The surprising effects mentioned are, in part, in combination with filters of particular retention which are customary in themselves, preferably in the so-called INCOM process (applicants' patent specifications DE 2,903,300, DE 3,119,330, and DE 3,414,625). It is assumed that this is achieved by using highly volume activated tobacco, which has been carefully obtained by an expansion process. As shown in FIG. 1, approximately constant condensate yield is obtained at each suction.

Cigarettes activated by volume by the INCOM process are particularly characterized by the preservation of cellular tissues of tobacco fibers, which does not occur to this extent in other known processes. However, many cigarettes whose volume is activated by other processes are significantly damaged in their cellular tissues, and with this, a significant loss of fragrance and nicotine can sometimes occur, which does not occur at all in INCOM cigarettes. Here, relevant fragrance components, nicotine, and secondary alkaloids are best "free". That is, they can be carried particularly easily by only a small amount of air or mainstream smoke.

These highly effective scents and nicotine mobility of INCOM cigarettes are believed to have a beneficial effect, particularly in that the amount of air sucked through the highly ventilated glow cones according to the invention is extremely small. . Likewise, significantly different from conventional cigarettes and the low filling density and relatively low pull resistance of the cigarette strand of the cigarette according to the invention (although the cigarette strand is surprisingly hard Extremely low strand retention, as determined by the < RTI ID = 0.0 > and no tendency to collapse, < / RTI > contributes to maintaining a very high amount of flavor for extremely mild cigarettes.

Finally, this surprisingly high flavor amount can be enhanced by using, at the lowest value, multiple filters of very high retention that make up part of the present invention. The retention or efficiency of the filter is determined by the amount of material retained in the filter (condensate and nicotine) with respect to the amount of incoming material. Such a multi-filter, also called a multi-filter or combination filter, consists of at least two different filter parts or filter parts, the filter parts being optionally spaced apart from one another (hollow chamber filter) and are different from each other in the filter material It is possible to have different smoke constituents at different degrees and thus be in harmony with one another "with respect to taste", especially with a high degree of ventilation suitable for this active taste effect.

Typically, extremely mild cigarettes with high retention, non-ventilated filters result in unacceptable high suction resistance, whereas very well ventilated filters with filter of the same range and thus with acceptable suction resistance. In the case of poultry, there is enough "warm air", ie, mainstream smoke with a low flavor. This is undoubtedly avoided in a cigarette according to the invention in an unexpected way.

It goes without saying that the applied weight of the tobacco of the cigarette according to the invention, which is significantly lower than that of a conventional cigarette, significantly reduces the class smoke. This desired effect is achieved by using commercially available or specific tobacco rolling papers that reduce class smoke, for example cigarette rolling papers according to the applicant's patent specifications DE 3,802,645 and DE 3,802,646, and cigarettes. The shapes can be strengthened by correspondingly smaller dimensions. Thus, in a particular embodiment, because of the extremely low mainstream smoke and class smoke emissions while maintaining a “typical” cigarette appearance, it is not necessary to use expensive materials and complicated manufacturing techniques without any of the known “smoke free” cigarette substitutes. Smoking articles are provided which are generally arranged close to one.

The tobacco mixture is preferably subjected to an inflation or expansion process as a whole. In this process, the volume of the tobacco mixture becomes larger, and correspondingly, with respect to the initial volume, the "filling capacity" of the tobacco mixture is increased. In this process, however, only leaf or leaf tobacco containing intact cellular material is inflated (ie, the volume is activated), and thus, conventional sheet tobacco is so inflated when it is mixed. I do not lose. As a result of the swelling (calculating swelling) of the entire mixture consisting of inflatable leaf tobacco and inflatable sheet tobacco, the closely mixed fine tobacco segments are exposed to mechanical treatment and heat treatment. This presumably encourages the time course of transfer of nicotine from sheet tobacco to leaf tobacco or from high nicotine leaf tobacco to low nicotine leaf tobacco, so that a more homogeneous nicotine distribution in the tobacco mixture is achieved. This process, although more expensive, provides a uniform mainstay taste taste during smoking of cigarettes. However, only a portion of the tobacco mixture, for example leaf tobacco, may undergo an inflation process, and the portion of the tobacco mixture used that does not inflate, such as tobacco or leaf veins, which are conventional in itself. It may consist of "industrial" tobacco. The latter part can serve to adjust the taste of the cigarette according to the invention with respect to taste, for example in the addition of known casings and taste substances which contribute to the desired overall flavor. . Finally, the addition of the cover and / or taste substances to the entire tobacco mixture or parts thereof may occur before swelling, ie before or after the expansion process. The finished tobacco mixture is then treated with the filtered cigarette according to the invention in a known manner in a conventional cigarette maker which accommodates multiple filters.

In one example of the tobacco mixture, the other manufacturing conditions are the same year, the use of sheet tobacco is completely excluded, in which case the entire final cigarette-tobacco mixture can be volume activated. In this case, natural cigarettes are used which have within 6% by weight of nicotine, in particular cases within 8% by weight of nicotine.

The invention is explained in more detail by the following examples.

Example A

33% air dry tobacco,

28% firepower dry tobacco,

14% orient,

25% sheet tobacco

From tobacco mixtures with American Blend traits, having an average nicotine content of 3.4% and volume activated as a whole (i.e. after mixing) by the INCOM process to increase the filling capacity by 60%. Do you smoke cigarettes with a weight of 460 mg? Cigarette strands having a total weight of 500 mg including paper (diameter: 7.9 mm, length 59 mm) were prepared. The packing density of these cigarette strands was 160 mg / cm 3, and cigarette hardness (Germany Publication No. 3,929,155). Measured by the method according to 2.25 mm penetration depth. The porosity of the rolling paper was about 40 CORESTA.

These strands were provided with double filters (paper / acetates) and treated with non-porous wrappers in a conventional manner so that the strands formed filtered cigarettes. Here, paper represents a commercially available cellulose-web filter and acetate represents a conventional cellulose-acetate fiber filter. The suction resistance of the strand-side paper-filter portion of 12 mm length was 175 daPa, and the mouth acetate of 13 mm length. The suction resistance of the filter part was 15 daPa The filter ventilation caused by laser drilling provided a ventilation of 77% added air according to DIN 6565.

The smoke data (measured values according to DIN-ISO 3402/4387/10315 / 10362-1) of this cigarette (Al) are shown in Table 1. The smoke pH value was also described in particular by the method described by "Harris" and the like (32th order). Tob Chem. Res. Conf., 1978).

Table 1 also shows the corresponding values of the cigarette A1 and the other cigarettes A2, A3 only with respect to the filter. In these cases too, a paper / acetate double filter having a 12 mm long strand-side paper-filter part and a 13 mm long mouth acetate-filter part was used, but in each case the filters used were different from the different suction resistances. It had a value of ventilation.

TABLE 1 Filter data and smoke data of cigarettes according to Example A

Sensory findings of all three cigarettes showed at least equivalent to, and better than, conventional, ultra-lingt cigarettes with K-values of 1 mg or more.

Example B

40% air dry tobacco,

20% firepower dry tobacco,

15% orient,

25% sheet tobacco

Application of tobacco from the US blended traits of tobacco blend, which has a flat nicotine content of 3.6% and a volume activated as a whole (i.e. after mixing) by the INCOM process such that the filling capacity is increased by 55%. Cigarette strands (diameter: 7.9 mm, length: 59 mm) weighing 450 mg and a total weight of 490 mg including a rolling paper were prepared. The packing density of these cigarette strands was 155 mg / cm 3 and the cigarette hardness (measured by the method according to German Publication No. 3,929,155) was 2.4 mm penetration depth. The porosity of the paper was 40 CORESTA.

These strands were provided with double filters (paper / acetates), in particular as in Example A, ie laser perforated with a 12 mm long strand side paper-filter part and a 13 mm long mouth acetate-filter part. The strands were treated with a non-porous wrapper in a conventional manner to form a filtered cigarette.

Table 2 shows the smoke data of three different cigarettes B1, B2, B3 in terms of suction resistance and ventilation of the filter parts.

TABLE 2 Filter Data of Cigarettes According to Example B

The results of sensory investigation of these three cigarettes generally indicate that they are equivalent to the conventional extreme mild cigarettes having a K value of 1 mg or more, but the cigarettes according to Example B are the conventional ordinary extreme mild cigarettes. It appears to be stronger (more reactive) than either.

Example C

Pristine

50% air dry tobacco,

35% firepower dry tobacco,

15% Orient

Application of tobacco from the US blended traits of tobacco blend, which has an average nicotine content of 3.5% and has a volume activated as a whole (i.e. after mixing) in the INCOM process with a 60% increase in filling capacity. Cigarette strands (diameter 7.9 mm, length: 59 mm) weighing 420 mg and having a total weight of 460 mg including a rolling paper were prepared. The packing density of these cigarette strands was 145 mg / cm 3 and the cigarette hardness (measured by the method according to German Publication No. 3,929,155) was 2.4 mm penetration depth. The porosity of the paper was 40 CORESTA.

These cigarette strands were provided with double filters (paper / acetates), in particular similar to Example A, ie laser perforation having a 12 mm long strand side paper-filter part and a 13 mm long mouth acetate-filter part. The strands were treated with a non-porous wrapper in a conventional manner to form a filtered filter cigarette.

Table 3 shows the smoke data of cigarettes according to Example C.

TABLE 3 Filter Data and Smoke Data of Cigarettes According to Example C

Sensory investigation results of these cigarettes generally showed surprisingly equivalent to conventional lights / light cigarettes having a K value of 4-7 mg and a corresponding nicotine value, but in Example C The resulting cigarettes have been shown to be stronger (more reactive) than some of the conventional Rights / Light cigarettes.
