Definitions
- the invention relates to a filter cigarette.
- the smoke of cigarettes is composed of a particle and a gas phase.
- the smoke is filtered with the aid of cellulose acetate.
- the gas phase is often not lowered to a satisfactory extent, so often other design features are adjusted. For example, it is common to provide cigarettes with a relatively high ventilation, which causes the gas phase to be additionally diluted with air.
- Another possibility of additional gas phase reduction is the use of gas phase-active, that is reducing the gas phase, substances in the filter.
- cigarettes are usually smoked to the ISO standard. If alternative smoking conditions are selected, as is the case for example. B. under intense smoking conditions (see definitions below) in Canada, gas phase values are significantly higher.
- Filter cigarettes are known from the prior art, which influence the tobacco smoke with the aid of gas-phase-active substances in such a way that the amount of gas phase in the mainstream smoke inhaled by the smoker is reduced.
- filter cigarettes are on the market whose gas phase values are reduced by the addition of gas phase active substances, such as activated carbon.
- gas phase active substances such as activated carbon.
- Activated carbon filters in which the activated carbon is introduced into a chamber, are used for a long time and especially in Japan and are known from WO 02/37990 A2 or from other documents such. B. DE 42 056 58 A1 or WO 00/49901 A1.
- the filter consists of a filter segment with activated charcoal and a filter segment with ion exchange resins and optionally a mouth-side filter segment made of cellulose acetate. Comparable cigarettes are described in WO 03/015544 A1 and WO 2004/103099 A2.
- the gas phase reduction is also influenced by the combination of the design parameters of a filter cigarette, which includes not only the filter additives, but also the nature of the tobacco, the wrapping material and the filter components.
- the gas phase is not lowered to a satisfactory extent in the cigarettes described.
- the values for the total gas phase content G ges are more than 1200 ⁇ g / cigarette, measured according to ISO.
- a further disadvantage is that conventional gas phase active cigarette filters lose their effectiveness after a certain storage time.
- the cigarettes according to the prior art are often added further substances either in the tobacco mixture or in the filter, such as palladium to tobacco as in WO 02/37990 Al.
- the disadvantage here is the high costs and difficult manufacturing conditions. Also disadvantageous are complex and expensive Multifilterkonstruk- tions with a variety of different adsorbents or expensive special materials.
- the object of the invention is to provide a filter cigarette with a significant gas phase reduction of the tobacco smoke. This gas phase reduction should also be given under so-called Intense-Abrauch discipline (see below).
- the gas phase efficiency of the filter should be possible over a longer period, eg. B. the period of storage of the cigarettes, be constant or at least only slightly change.
- the filter cigarette according to the invention has a tobacco rod, a filter and a wrapper (preferably made of cigarette paper, filter wrapping paper and tipping paper).
- the filter contains a filter material matrix with gas phase reducing substances.
- the tobacco of the tobacco rod preferably consists of an American Blend mixture or a Virginia blend.
- the tobaccos of the tobacco blend are preferably provided with an additive level below 1% of non-volatiles relative to the tobacco dry substance; most preferably no additives are used.
- the tobaccos are preferably selected so that the TSNA content (TSNA: tobacco-specific nitrosamines) of the total mixture is less than 2 ⁇ g / g tobacco. It is even more advantageous if the content of TSNA in the tobacco is below 1 ⁇ g / g of tobacco.
- the tobacco may additives or additives such.
- the cigarette paper surrounding the tobacco rod is preferably porous and has a porosity of more than 40 CU (Coresta Units) or more than 60 CU. To achieve particularly low NFDPM values (see below) in the range of 4-7 mg / cigarette, the porosity is preferably greater than 300 CU.
- the naturally porous cigarette paper can additionally be electroperfused, mechanically perforated or laser perforated.
- the cigarette paper preferably contains a relatively high mullet salt content to lower the CO content in the smoke.
- Usual Glimmsalzmengen are at 0, 7%. Glimmsalzmengen of 1, 3% or more, preferably 2% are used according to the invention. Preferably, sodium / potassium citrates are used.
- the basis weight of the cigarette paper is preferably lower than conventional comparable cigarettes and is at 22 g / m z .
- the filter may for example consist of one, two, three, four or five filter sections and preferably has two filter sections. If the filter has more than one filter section, a filter section is preferably arranged on the mouth side, which does not contain any substances which reduce the gas phase. Different gas phase reducing substances can be introduced in one or in different filter parts. In the case of several filter parts, these can be arranged longitudinally one behind the other or else arranged coaxially.
- the filter material (the matrix and others) contains, for example, cellulose, cellulose derivatives (preferably cellulose acetate), polymers such as polyolefins (polypropylene, polyethylene), polyesters or mixtures thereof.
