Definitions
- the invention relates to a ventilated cigarette, the mouthpiece zone of which consists of tobacco or a filter or a hollow mouthpiece and there contains at least one ventilation zone in the casing or wall, wherein in the mouthpiece zone or between this and the tobacco rod or in the latter a polymeric non-crimped staple fibers and / or filaments existing element is arranged so that it is, seen from the mouth-facing end of the mouthpiece zone, behind the ventilation zone, the staple fibers and filaments each having a diameter of 0.1 to 20 microns.
- a generic ventilated cigarette is known from German Offenlegungsschrift (DE-A) 22 43 349, the mouthpiece zone of which consists of a filter or a hollow mouthpiece and there contains air holes in the casing or wall, with a disc of a tightly packed one between the mouthpiece zone and the tobacco rod Layer of fine fibers is arranged so that it is from the mouth-facing end of the mouthpiece zone, behind the air holes, the fine fibers, which consist for example of a synthetic textile material, each from 0.01 to 10 microns or 0.1 to 100 microns.
- a filter for tobacco smoke which is composed of several filter elements, at least one of the filter elements consisting entirely of non-crimped fibers made of thermoplastic polymeric non-absorbent material, which have a diameter of less than about 5 microns and the like the greater part is arranged so that the fibers are transverse to the tobacco smoke flow.
- this known filter is one without a ventilation zone (s).
- this known filter has the disadvantage that it becomes clogged after only a few puffs when a cigarette provided with such a filter is smoked, ie that a large amount of condensate is very quickly deposited on the filter element made of non-crimped fibers made of thermoplastic polymeric non-absorbent material, which means the draw resistance is increased excessively.
- the invention has for its object to provide a ventilated cigarette of the type described above, with which the smoke yield and taste are evened out and the overall smoke values are lowered both in the particle and in the gas phase.
- polymer blends or copolymers can also be used.
- the staple fibers and filaments of an element according to the invention consist of a single, ie of the same polymeric material; however, the element can also consist of a mixture of staple fibers and / or filaments made of two or more polymeric materials.
- the staple fibers and filaments of an element according to the invention can have the same diameter; however, it can also be staple fibers and filaments of different diameters.
- the element according to the invention is preferably located at a distance of up to 30 mm from the end of the mouthpiece zone facing the mouth.
- the staple fibers and filaments of an element according to the invention each have a diameter of 1 to 5 ⁇ m.
- Table 3 shows the values determined for the degree of ventilation and the draft resistance for the filter cigarette C during smoking.
- Table 3 train Degree of ventilation in percent Draw resistance in Pascal 0 17.5 1028 1 20.0 1125 2nd 22.4 1241 3rd 21.8 1226 4th 21.7 1230 5 20.6 1213 6 19.9 1200 7 20.5 1255 8th 19.9 1246 9 21.9 1376
- Tables 2 and 3 show in particular that the degree of ventilation of the original filter cigarette only increases by about 11 percent up to the ninth pull, while the degree of ventilation of the filter cigarette C increases by about 25 percent, which ultimately leads to a smoothing of the Tobacco smoke yield per train and thus also leads to a reduction in the overall smoke yield in both the particle and the gas phase.
- Table 4 shows the values determined for the degree of ventilation and the draw resistance for the filter cigarette A during smoking.
- Table 4 train Degree of ventilation in percent Draw resistance in Pascal 0 23.7 1298 1 26.7 1437 2nd 30.1 1604 3rd 30.0 1624 4th 30.6 1676 5 31.6 1767 6 32.3 1862 7 34.5 2029 8th 37.3 2267 9 43.0 2609
- Table 5 shows the ventilation degree and draft resistance values determined for filter cigarette B during smoking.
- Table 5 train Degree of ventilation in percent Draw resistance in Pascal 0 32.3 1692 1 34.5 1809 2nd 37.8 1991 3rd 39.1 2061 4th 41.2 2184 5 43.5 2325 6 47.2 2557 7 53.2 2945 8th 64.4 3695 9 74.3 4277
- discs A and B in the - ventilated - filter cigarettes achieve a very significant increase in the degree of ventilation during smoking, which naturally leads to a very strong equalization of the smoke yields per train and a reduction the total smoke yield per cigarette leads.
- the invention has the following advantages:
- the ventilated cigarette according to the invention shows - compared to commercially available ventilated cigarettes - an equalization of the smoke yield when smoking step by step, whereby the taste of the tobacco smoke remains practically the same during the smoking. Furthermore, a reduction in the overall smoke yield is achieved in both the particle and the gas phase per cigarette.
