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

The invention relates to a ventilated cigarette cigarette cigarette which finds application 6 of the tobacco industry. From DE-OS 32 28 950 there is known a cigarette with a ventilated cigarette with a volume activated (i.e., expanded) tobacco mixture whose nicotine content is 2-5%. This cigarette has a low CPC. filter - maximum 35%. Concentration values according to the examples vary between 7 and 17 mg " tar " connazate. DE-OS 36 338 801 is a known cigarette with a vent filter whose taste generally remains unchanged with each Tension. . This is achieved by the use of a special filtration material whose permeability to the venturi increases with increasing winter composition by the main stream of cigarette Zim. EP-A2-0 283 672 relates to nicotine and levalinic acid cigarette tobacco, respectively. nicotine levolate. Concentrated values of the cigarette-producing quench filter produced by S3 correspond to 7 mg of "tar". At this point in time 6 applications are known and cigarettes with a vent filter with condensate (K) and nicotine (N) values of 1 mg K and 0.1 mg N are placed on the market.

For example, this is the Reynolds / USA US cigarette with a combined value of <0.5 mg, as well as the Rothmans DUNHILL ULTIMATE LIGHTS cigarette with a value of less than 1 mg of tar, 0.1 mg of nicotine. Cigarette dispensers are confronted with the consumers who are satisfied with the taste of their taste, which is confirmed by the comparatively low marketing of cigarettes, and by Zruga by the internal smoker tests. It is an object of the invention to provide an ultralight cigarette filter, in which it is to be understood that the preservation of an almost constant and qualitatively elastic taste at each thrust but with extremely low congenital and nicotine values and at the same time minimal reduction of any undesirable Winter ingredients both in the base and in the secondary stream of the cigarette Zim, using customary equipment at a discounted price, especially without a complex filter technology. The solution of this delay within the scope of the invention is achieved according to the features of the independent claim, the preferred embodiments being mentioned in the dependent claims. For example, the combination according to the invention can minimize all undesirable winter ingredients both in the gas and in the corpuscular phase, and the smokable and aromatic substances desired, including nicotine, are available to the fullest extent for light cigarette enthusiasts . This .....- 4.-,

an unexpected effect is objective: a value level, e.g., K <1 mg / N <0.1, and subjective: a completely satisfactory flavor - from the first puff there is approximately a constant quantity of "flavor candy", as can be seen from Fig. 1, wherein the amount of condensate available per pull is shown to the number of drops. It is this fact that is lacking in the ultra-light cigarettes, which leads to their inadequate perception. It is believed that said effects are achieved in part by the use of the so-called " "INCOM" technology (expanding method according to applicant's DE29 03 300, DE 31 19 330 and DE 34 14 65 patent) high volume activated tobacco, combined with common filters, a certain retention factor. There is thus a relatively constant presence of condensate of one pull, as illustrated in Fig. 1. Volumetric activated tobacco by the INCOM method is distinguished, above all, by the preservation of the cellular structure of the tobacco fiber, something which is not such a degree in other known technologies. The cellular structure of all volumetric-activated sub-technology tobacco is significantly disturbed, which in part can lead to large aromatic and nicotine losses in contrast to NCOM-tobaccos. Here, 6 are "revealed" important aromatic substances, nicotine and secondary alkaloids, i. they can be particularly easy to transfer even from low amounts of air or air. main stream of cigarette smoke.

It is believed that this relatively effective aromatic and nicotine mobility overwhelms all of the lNCOM tobacco has a favorable effect on the extremely low amount of air that is inhaled through the glowing cone in the highly ventilated cigarette of the invention. The extremely low stagnant capability due to the low seal and the relatively low resistance of pulling the still and non-collapsible cigarette pillar of the cigarette according to the invention contributes to maintaining a very high flavor for one ultra light cigarette. Ultimately, this unexpectedly high taste range at the lowest values could be favored by the use of the part of the invention of a highly retentive multi-layer filter whose retention capacity, efficiency is determined by the total amount retained in the filter substance (condensate and nicotine) relative to the incoming amount of substance. This multi-layer filter, also called multi- or wagon-filter, consists of at least two different filter units or sections, possibly spaced apart (hollow chamber filters), made from separate filtering materials and retaining thus in varying proportions of smoke constituents and thus with an opportunity to agree with each other in taste, above all with regard to the high degree of retention, in accordance with this positive effect in terms of taste. Typically, cigarettes from the ultralight segment with non-returnable high retention filters produce an unacceptably high drag resistance or respiration. suction, and with high ventilation filters of cigarettes with filters of the same segment, acceptable drag resistance often results in the take-up of "warm air" only, of a mainstream jet with a low taste range, which is unexpectedly avoided in the cigarette object of the invention. Due to the substantially low mass of tobacco input, the subject-matter of the invention, compared to conventional cigarettes, is a significantly reduced secondary smoke. This desired effect can be enhanced by the use of the proposed drug or cigarette paper for reducing the secondary smoke, for example cigarette paper, according to the applicant's DE 38 02 645 and DE 38 02 646 patent documents, low-sized cigarette formats. Thus, in a particular form of embodiment, it is convenient to smoke the cigarette which, based on its extremely low emissions of primary and secondary stream of cigarette smoke, while preserving the "classical" cigarette habit, can generally be attributed to one of the known "smoke-free cigarette surrogates" without, however, relying on their expensive materials and complex manufacturing technologies. The tobacco mixture is generally treated mainly by the method of expansion or expansion. This gives rise to an increase of the mixture and thus, respectively, an increase in the filling ratio of the tobacco mixture to the initial volume. Here, however, only that part of the tobacco containing laminar cell material is discharged or reactivated. ordinary leaf tobacco if it is impurities. By means of the compressible expansion of the whole of the mixture of suitable for blowing laminar tobacco and unfit for blown tobacco tobacco, the well-mixed and finely chopped tobacco particles are deposited together in both mechanical and thermal treatment. Thus, the time-dependent migration of nicotine from leaf tobacco to laminar tobacco, respectively, is beneficial. of the laminar tobacco with a high nicotine content to lower tobacco nicotine, thus achieving a homogeneous distribution of nicotine in the tobacco mixture. Indeed, this method is more cost-effective, but it reflects the unmistakable taste effect of the main smoky cigarette smoke when smoking the cigarette. However, only a portion of the tobacco mixture, such as laminar tobacco, may be subjected to swelling, whereas the unspent portion of the mixture used may consist of virtually conventional or "technical" tobaccos such as ripenish. the latter may, for example, serve for the taste modulation of the reactivity of the cigarette according to the invention as well as the addition of the already known humectants and flavors which contribute to the desired general taste effect. Humidifiers may be added to the general tobacco blend or parts thereof before or after the blowing or wiping process. The ready-made tobacco blend is then processed in a manner known to conventional cigarette machines by the application of the multilayer filters in the filter cigarettes of the invention. In one of the ways of preparing the tobacco blend, but under otherwise the same manufacturing conditions, no sheet tobacco is used at all, so that the final tobacco blend is suitable for volume activation. In this case, natural tobaccos are used without foreign impurities of the order of up to 6 pounds. % nicotine, and in special cases up to 3 mass. % nicotine. The invention is illustrated in more detail by the following examples:

Example A Of a tobacco blend with American Blend-Character consisting of 33% air-dried tobacco 28% air-dried tobacco 14% oriental tobacco 25% sheet tobacco with an average nicotine content of 3.4% fully activated by INCOM technology (ie after mixing) with an increase in filling capacity of about 60% produced cigarettes (diameter 7.9 mm and length 59 mm) with a useful mass of 460 mg and a total mass of 500 mg cigarette paper. The bulk density of the cigarette is 160 mg / cm3, and the hardness of the cigarette (measured by DE-OS 3929155) has a 2.5 mm penetration depth. The porosity of the cigarette paper is in the order of 40 kerosene. Cigarettes are wrapped in double filters - acetate paper and sneeze coating paper, and thus processed in the usual manner in filter cigarettes, with the term PAPER here being the commercial standard cellulose-fiber filter, and paper - the classic filter based on cellulose and acetate fiber. The pulling resistance of the long 12 mm end of the tobacco topsheet filter is 175 daPa, and this thrust from the 13-milliliter end of the acetate filter on the side of the mouth is 15 daPa. The laser ventilation provided by laser perforation provides, according to the DIN 6565 standard, a ventilation rate of 77% secondary air.

The smoke bands for this type A1 cigarette (with measurements made according to DIN-ISO 3402/4337/10315 / 10362-1) are shown in Table 1. The pH value of the bead was also measured, as described by Xapuc / Harris et al . (32th Tob, Czechoslovak Res., 1978). Table 1 also shows the corresponding values for type A2 and A3 cigarettes that differ from cigarette A1 only on the filter. In these cases, a filter was used with a filter paper filter from the tobacco column of 12 mm and a filter cut of acetate paper from the mouth with a 13 mm long, but with different stirring resistances and a different value of the degree of ventilation.

The packing density of these cigarette poles is 155 mg / cm3 and the strength of the cigarette (measured according to DE-OS 3929155) is 2.4 mm penetration depth. The porosity of the cigarette paper is from the cut of 40 loops. The cigarettes are wrapped with Zero filters - Acetate paper and Sneposer lining paper and thus processed in a customary way in cigarettes with a filter as in Example A, i.

The smoke rate of the three cigarettes type B1, B2 and B3, which distinguish between the resistance of the filter sections and the degree of ventilation, are given in Table 2. 11 with an average nicotine content of 3.5%, volume-activated INCOM technology after mixing), an increase in filling capacity of about 60% produced cigarettes with a diameter of 7.9 mm and a length of 59 mm with a useful tobacco mass of 420 mg and a total mass together with a cigarette paper of 460 mg. The packing density of these cigarettes is 145 mg / cm3, and the hardness of the cigarette (measured in accordance with DE-OS 3929155) has a 2.4 mm penetration depth. The cigarette paper porosity is in the order of 40 coresta. The cigarettes are coated with double filters - acetate paper and non-porous lining paper and thus processed in the usual manner in cigarettes with a filter similar to Example A, i.
