Definitions
- the invention relates to a filter cigarette according to the preamble of patent claim 1.
- Filters for tobacco smoke that consist entirely of tobacco have long been known. They have good filter properties and are particularly attractive to many smokers for reasons such as biodegradability, natural origin, ecological aspects. By using highly aromatic tobacco, this leads to improved taste properties of tobacco smoke.
- EP 0 232 166 A2 describes a ner process for producing a filter cigarette with a tobacco filter, the mouth end of the tobacco filter being solidified with a binder in order to prevent tobacco from crumbling out.
- the object of the invention is to provide a filter cigarette with a multi-part filter, in which a significant improvement in taste is achieved and the disadvantages of known tobacco filters, such as the lingual, labial and optical as well as sensory interferences, are avoided. Furthermore, the natural filter properties of the tobacco should be used and especially addressed to consumers who prefer natural products.
- Another object of the invention is to further improve the taste of the filter cigarette with tobacco filter by means of at least one additional structural hollow or flow filter element.
- a smoking product is provided according to the preamble of claim 1, which is characterized in that the filtration system additionally has a hollow filter to improve the sensory properties, which is coaxially attached to the mouth of the tobacco filter part.
- An essential part of the invention consists in avoiding lingual, labial and haptic irritation by using the mouth-side hollow filter part, which also has pleasant haptic and optical properties due to its surface smoothness.
- Another advantage of the invention is that the use of aromatic tobacco in the tobacco filter results in a significantly improved taste. At the same time, this enables Measure a significant reduction in the cost of materials, since less aromatic and therefore cheaper tobacco can be used in the strand. Accordingly, the essence of the invention is the formation of the filtration system from a tobacco filter on the one hand and a hollow filter on the other.
- Another advantage is the improved appearance due to the increased distance between the tobacco surface and the mouth end of the filter.
- the use of a hollow filter part in a tobacco filter saves material costs for the highly aromatic filter tobacco.
- aromatic tobacco filter materials tobacco of good leaf quality, e.g. Tobacco with a very low proportion of expanded tobacco, rib or foil tobacco or tobacco that has previously been subjected to aroma enrichment.
- the aromatic tobacco portion in the tobacco filter element significantly reduces the negative taste impression compared to one-piece artificial filter elements.
- thermal methods can be used in a manner known per se.
- the strand wrapping material can consist of at least one wrapping layer of reconstituted tobacco or natural tobacco leaf, the cover sheet being attached in a spiral winding.
- FIG. 1 shows a smoke product with tobacco filter and hollow filter mouthpiece
- FIG. 2 shows a smoke product according to FIG. 1 with ventilation zone
- Figure 3 shows a smoke product according to Figure 1 or 2 with a prefilter
- Figure 4 shows a smoke product with a tobacco filter in the filter core
- Figure 1 shows a first embodiment with a tobacco rod 1
- Tobacco filter section 2 on the mouth side of which a hollow filter part 3 is attached, which can have one of the cross-sectional shapes shown in FIG.
- the tobacco smoke flow is directed through the hollow filter according to the Coanda effect so that the flow takes place along a solid surface.
- this swirl boundary surface effect also produces an increased condensate separation on the surface of the hollow filter, without this causing an additional increase in draft resistance.
- the tobacco filter as shown in FIG. 2, can be ventilated.
- the arrangement of the ventilation means e.g. a row of perforations 7 is preferably provided at the end of the filter on the strand side. Both the main flow smoke and the ventilation air supplied then flow through the aroma-rich tobacco over the longest possible distance, which leads to the maximum aroma enrichment of the smoke flow supplied to the consumer.
- FIG. 3 shows a smoke product with a ventilated tobacco filter section 2 and a hollow filter 3 adjoining the mouth, with the tobacco filter section 2 on the side of the tobacco rod 1 a prefilter 6 is attached, which serves for prefiltering the tobacco smoke and / or for ventilation.
- a tobacco filter system according to the invention can be used in the segment of lights and ultralights smoke products.
- the prefilter 6 can be made, for example, of cellulose, cellulose acetate, activated carbon-containing paper, activated carbon-containing cellulose acetate, polyolefins such as polyethylene or polypropylene.
- the material of the prefilter 6 can be mixed with flavors or functional additives.
- a closed flow filter element made of known filter material (polyethylene, creped cellulose, cellulose acetate) is attached to the mouth of the tobacco filter section.
- Tobacco portion in the tobacco filter element significantly reduces the negative taste impression compared to one-piece conventional filter elements.
- FIG. 4 shows a smoke product with a coaxial or core filter with a tobacco core 8 and jacket 9 made of a different filter material, for example cellulose acetate. It can be seen that the jacket 9 extends from the tobacco rod 1 to the mouth end of the cigarette, while the tobacco core 8 encased by the jacket ends at a distance from the mouth end of the filter, so that the hollow filter 3 is formed in this area.
- a coaxial or core filter with a tobacco core 8 and jacket 9 made of a different filter material, for example cellulose acetate.
- the hollow filter 3 is either a hollow tube or a socket according to FIG. 5a, or a tube or socket with a concentric inner tube according to FIG. 5b.
- the inner tube 4 has a circular cross section, while the cross section in the embodiment according to FIG. 5c has a rectangular shape and according to FIG. 5d has a further geometric shape.
- Other cross-sectional shapes for the inner tube 4 are also possible.
- FIGS. 5e and 5f also show webs 5 which support the inner tube 4 in an outer hollow filter part 3. It is pointed out that the embodiment according to FIG. 5f differs from the embodiment according to FIG. 5e in that the inner tube 4 is filled, for example, with cellulose acetate.
- the upstream tobacco filter improves the overall negative impressions of the usual filters, which consist entirely of filter material such as paper or plastic.
- the tobacco which is used in the filter, is brought to a tobacco temperature between 60 ° C and 150 ° C, preferably 80 ° C and exposed to a high relative humidity and with a cutting width of 0.3 for a period of between 1 minute and 15 minutes mm to 0.6 mm cut.
- the tobacco filter has a hollow filter part on the mouth side, a so-called recess filter, and is connected to the tobacco rod on a conventional cigarette machine by means of a wrapping paper.
- the cigarettes have an attractive visual appearance and there are no lingual or labial disturbances when smoking.
- Example 2 200 kg of tobacco are subjected to a casing preparation, cut in a fine cutting width of 0.3 mm to 0.6 mm and processed into filter parts.
- the mouth-side hollow filter part consists of polyethylene, the inner tube being connected to the outer wall of the hollow filter via three webs.
- the tobacco filter and hollow filter parts are processed into double filters and attached to the tobacco rod with the help of wrapping paper.
- the wrapped tobacco rod contained a tobacco blend with a high proportion of ribs and inexpensive tobacco.
- the tensile resistance of the inventive filter was 82 mm WS, which was in the range of the tensile resistances of filters made of conventional materials.
- Cigarette according to the invention showed a significantly better taste compared to a cigarette with a one-piece tobacco filter without a hollow mouthpiece. Furthermore, the test subjects were asked about their visual and haptic impressions. There was a unanimous opinion that the optical, haptic and lingual or labial interference impression is significantly reduced compared to the comparative cigarette.
