Definitions

  • the invention relates to a ventilated filter cigarette according to the preamble of the claim 1.
  • Filter constructions for use in tobacco smoke filters which consist of several filter parts Different material properties exist, are the solution in the prior art various tasks.
  • EP 474 940 B2 and EP 608 047 B1 describe smoke filters in which a middle core segment consists of a filter material different from the jacket. These smoke filters are also called core or coaxial filters.
  • the filter consists of two longitudinal filter sections, namely the ventilated core filter part on the strand side and a monofilter part on the mouth side, the mouth-side monofilter part having an aesthetic effect.
  • the disadvantage of the smoke filters mentioned is that in any case the covering of the inner core of the core filter section consists of a material which is permeable to the smoke, so that the smoke can flow perpendicular to the interface between the core and the jacket of the core filter.
  • EP 0 558 166 B1 describes a ventilated filter cigarette which likewise has a monofilter section at the mouth end and a core filter section on the strand side.
  • this filter cigarette has a hollow chamber between the two filter elements, which is filled with an adsorbent (e.g. activated carbon).
  • an adsorbent e.g. activated carbon
  • EP 0 880 904 A1 and DE 39 01 226 C1 fulfill the task of realizing a cigarette with particularly low condensate values, which is achieved primarily by the coaxial structure of the tobacco rod ,
  • a disadvantage of this design is the high cost of special manufacturing units that are necessary for the production of the coaxial strand.
  • EP 539 191 B1 sets itself the task of providing a ventilated filter cigarette with a particularly light weight.
  • the disadvantage here is that the densities of the materials used (both tobacco rod and filter) have to be minimized in order to realize a particularly light-weight cigarette, which extremely limits the possibilities of varying the equipment of the cigarette.
  • the ventilation zone is located in the filter section on the side of the line.
  • the object of the invention is to provide a ventilated filter cigarette which does not have the disadvantages mentioned above and whose filter elements bring about a reduction in the particle phase of the smoke (such as nicotine) and at the same time achieve a disproportionate reduction in the gas phase smoke constituents, the filtered smoke should retain a composition that is acceptable in terms of taste to the consumer.
  • the filter should have a wide range for the above advantages Enable sensory, haptic and optical design.
  • Another task is to separate the filter's drag from the retention of the To decouple filters, i.e. an increase in the retention capacity for smoke constituents achieve without a sharp increase in tensile resistance, as in conventional Filter constructions is inevitably, you have to put up with.
  • Another object of the invention is to provide a product with the advantages mentioned above Provide markets in which chamber filters and especially those that use activated carbon filled, are rejected for both sensory and haptic reasons.
  • a filter cigarette of the aforementioned type, further comprising the characterizing features of claim 1 serves to achieve this object.
  • This filter cigarette consists of a strand part 10 and a filter 20.
  • the strand part 10 is of a one-piece tobacco rod 11 and one surrounding the tobacco rod 11 Envelope 12 formed.
  • the filter 20 consists of at least two filter parts 22 and 23 and is connected to the strand part 10 by a wrapping paper 13 which is at least 3 mm is longer than the filter 20.
  • the tobacco rod 11 is usually between 55 and 75 mm long, while the length of the filter 20 is from 21 to 27 mm.
  • the filter 20 is ventilated in the area of the mouth-side filter part.
  • the degree of ventilation can in the range from 10 to 90%.
  • the wrapping paper 13 In the area of the mouth-side filter part 22 is the wrapping paper 13 with ventilation holes 14 provided as ventilation means in the form of 1 to 3 rows, preferably 2 rows of Holes are arranged around the filter 20, in the area of the strand-side filter part 23 the wrapping paper 13, however, completely impermeable.
  • ventilation holes 14 ventilation air is drawn into the filter 20 when smoking, which leads to the fact that in the A disproportionate lowering of the particle phase compared to lowering Gas phase components of tobacco smoke is achieved. In one embodiment, this can Ventilation means also little, up to about 2 mm, over the mouth-side filter part in the protrude from the string-side filter part. The ventilation air after a redirection also sucked into the mouth-side filter part 22.
  • Ventilation holes for example on mechanically or electrostatically or through laser perforations. Others too Known ventilation means are tubes, cannulas or material savings.
  • the mouth-side filter part 22 consists of at least one filter segment.
  • the mouth side Filter part 22 can also consist of two or more filter plugs, as shown in FIG is. This gives a higher possibility of variation of the filter materials, e.g. the possibility, in addition to the ventilated filter element 22b, on the mouth side To use filter element 22a, which is embossed on its visible cross-sectional area or May have coloring.
  • the strand-side filter part 23 forming a coaxial filter has a core 24 and one Core coaxially surrounding jacket 26.
  • the pressure drop of the core 24 can be between 10 and 50 mmWS lie.
  • the jacket 26 is designed such that its pressure drop is at least around the Factor 2 is greater than that of the core 24.
  • the jacket 26 can also essentially be impermeable to smoke.
  • the surface 25 of the core 24 is essentially made impermeable to smoke or enveloped in smoke.
  • the construction of the string-side filter part 23 causes the smoke primarily through the core 24 flows.
  • the narrowing of the cross-section reduces the smoke flow rate significantly increased within this core segment, which is inherently an increase in train resistance with relatively low retention.
  • An analogous effect is achieved if the Cross-sectional narrowing of the material through which smoke flows is caused by the fact that the core of the coaxial filter plug is designed to be almost impermeable and then the whole Smoke only flows through the mantle.
  • the filter materials for the filter 20 are sheet-like, fibrous or granular filter materials in question, such as cellulose, cellulose esters, preferably Cellulose acetate, meltblown filter material e.g. manufactured according to WO97 / 33026, airlaid filter material e.g. produced according to US 4,375,447, filter materials which can be mixed with additives, Tobacco e.g. according to DE 199 25 968, reconstituted tobacco, other easily rotten Filter materials or thermoplastic filter fibers.
  • cellulose cellulose esters, preferably Cellulose acetate, meltblown filter material e.g. manufactured according to WO97 / 33026, airlaid filter material e.g. produced according to US 4,375,447, filter materials which can be mixed with additives, Tobacco e.g. according to DE 199 25 968, reconstituted tobacco, other easily rotten Filter materials or thermoplastic filter fibers.
  • additives can improve the sensory, haptic or visual appearance serve cigarette according to the invention and / or an additional effect on the selective Have retention.
  • a filter element of the filter part 22 with activated carbon particles be provided to increase gas phase adsorption.
  • the mouth side Filter plugs must be colored.
  • Addition of the additives can be by sprinkling or spraying onto the filter materials, e.g. Fibers, or by direct injection into the material strand.
  • Possible additives for the filter material are: flavoring agents, acids or bases in suspended or dissolved form, or additives with a selective retention effect adsorbents such as activated carbon or SiO 2 .
  • Other additives with a selective retention effect are organic acids, bases, for example hydroxycarboxylic acids and their salts, metals and metal oxides, nitrogen components, ion exchange systems (for example zeolites), alcohols, polyphenols and porphyrin derivatives.
  • additives such as plasticizers e.g. Triacetin, triethylene glycol diacetate or Diethyl citrate, additives which accelerate photo degradation e.g. Titanium dioxide, the biodegradable additives, vitamins and / or color pigments for individual design of the desired filter construction in question.
