Definitions
- the invention relates to a ventilated filter cigarette according to the preamble of patent claim 1.
- Filter constructions for use in tobacco smoke filters which consist of several filter parts with different material properties, are used in the prior art to solve various tasks.
- the ventilation of filters is used to ensure a milder smoke and a lower pollutant supply.
- 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 strand-side core filter part and a mouth-side monofilter part, 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 AI and DE 39 01 226 Cl accomplish the task of using a cigarette with a coaxial arrangement of both the tobacco rod and the filter to realize low condensate values, which is primarily achieved 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 components, the filtered smoke should retain a composition that is acceptable in terms of taste to the consumer.
- the filter should allow a wide range of variation for the sensory, haptic and optical configuration.
- Another task is to decouple the tensile resistance of the filter from the retention of the filter, i.e. to achieve an increase in the retention capacity for smoke constituents without having to accept a strong increase in the draft resistance, which is inevitable with conventional filter designs.
- Another object of the invention is to provide a product with the advantages mentioned above for markets in which chamber filters and in particular those which are filled with activated carbon are rejected for both sensory and haptic reasons.
- a filter cigarette of the type mentioned at the outset serves to achieve this object and also has the characterizing features of patent claim 1.
- FIG. 1 shows the schematic illustration of a filter cigarette according to the invention.
- FIG. 2 shows the schematic illustration of a further embodiment of the filter cigarette according to the invention.
- This filter cigarette consists of a strand part 10 and a filter 20.
- the strand part 10 is formed by a one-piece tobacco rod 11 and a casing 12 surrounding the tobacco rod 11.
- 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 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 between 21 and 27 mm.
- the filter 20 is ventilated in the area of the mouth-side filter part.
- the degree of ventilation can be selected in the range from 10 to 90%.
- the wrapping paper 13 is provided with ventilation holes 14 as ventilation means, which are arranged in the form of 1 to 3 rows, preferably 2 rows of holes, around the filter 20, in the area of the strand-side filter part 23, however, is the wrapping paper 13 completely impermeable. Ventilation air is sucked into the filter 20 through the ventilation holes 14 when smoking, which leads to a disproportionate reduction in the gas phase components of the tobacco smoke being achieved in comparison with the reduction in the particle phase.
- the ventilation means can also protrude slightly, up to about 2 mm, beyond the mouth-side filter part into the strand-side filter part. After a deflection, the ventilation air is also drawn into the mouth-side filter part 22.
- Ventper holes are to be produced, for example mechanically or electrostatically or by laser perforations.
- Other also 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. 2. This gives a higher possibility of variation of the filter materials, e.g. the possibility, in addition to the ventilated filter element 22b, of using a further filter element 22a on the mouth side, which can have an embossing or coloring on its visible cross-sectional area.
- the strand-side filter part 23 forming a coaxial filter has a core 24 and a jacket 26 coaxially surrounding the core.
- 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 a factor of 2 greater than that of the core 24.
- the jacket 26 can also be essentially impermeable to smoke.
- the surface 25 of the core 24 is made essentially smoke-proof or is smoke-impermeable.
- the construction of the filter part 23 on the strand side causes the smoke to flow primarily through the core 24.
- the narrowing of the cross-section significantly increases the smoke flow velocity within this core segment, which inherently includes an increase in draft resistance with a relatively low retention.
- An analogous effect is achieved if the narrowing of the cross section of the material through which the smoke flows is caused by the fact that the core of the coaxial filter plug is designed to be almost impermeable and the entire smoke then flows exclusively through the jacket.
- the design options are extremely numerous within the specified objective, since the filter cigarette according to the invention allows the gas phase to be lowered proportionally without significantly influencing the speed, so that e.g. there is no typical effect which smokers call "yeast taste".
- Suitable filter materials for the filter 20 are sheet-like, fibrous or granular filter materials, such as cellulose, cellulose esters, preferably cellulose acetate, meltblown filter material e.g. manufactured according to WO97 / 33026, airlaid filter material e.g. manufactured according to US 4,375,447, additive filter materials, tobacco e.g. according to DE 19925 968, reconstituted tobacco, other easily decomposable filter materials or thermoplastic filter fibers.
- sheet-like, fibrous or granular filter materials such as cellulose, cellulose esters, preferably cellulose acetate, meltblown filter material e.g. manufactured according to WO97 / 33026, airlaid filter material e.g. manufactured according to US 4,375,447, additive filter materials, tobacco e.g. according to DE 19925 968, reconstituted tobacco, other easily decomposable filter materials or thermoplastic filter fibers.
- a filter element of the filter part 22 can be provided with activated carbon particles in order to increase the gas phase adsorption.
- the mouth-side filter plug can be colored.
- the pH values of the particle spectra and thus the taste impression can be influenced by adding acids or bases.
- the addition of the additives can be done by sprinkling or spraying on 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 acid bases e.g. Hydroxycarboxylic acids and their salts, metals and metal oxides, nitrogen components, ion exchange systems (e.g. zeolites), alcohols, polyphenols and polyphyrin derivatives.
- additives such as plasticizers e.g. Triacetiti, triethylene glycol diacetate or citric acid diethyl ester, additives which accelerate photo degradation e.g. Titanium dioxide, additives that promote biodegradability, vitamins and / or color pigments can be used for the individual design of the desired filter construction.
- plasticizers e.g. Triacetiti, triethylene glycol diacetate or citric acid diethyl ester
- additives which accelerate photo degradation e.g. Titanium dioxide
- additives that promote biodegradability e.g. Titanium dioxide
- vitamins and / or color pigments can be used for the individual design of the desired filter construction.
