Definitions
- the invention relates to a filter for a smokable article, in particular for a cigarette, wherein in the periphery of the filter grooves are pressed.
- filters are known in various embodiments.
- DE 33 04 763 A1 discloses a cigarette filter with a cylindrical filter body, with an air-permeable envelope for the filter body and with depressed in the circumference of the filter body grooves which extend, starting from the mouth-side end of the filter over part of the filter length ,
- the cylindrical filter body, and thus the grooves are attached to the tobacco rod by an air-permeable tipping paper, which is provided with ventilation openings.
- This filter should have a straightforward structure and achieve a substantially normal pressure drop across the cigarette.
- DE 36 01 959 A shows a further modification of such a filter, in which also the grooves are open to the mouth end of the filter.
- at least one perforation in the region of the grooves for introducing air through the sheath into the filter body is provided. This is to provide a filter with improved air introduction into the filter rod.
- the tipping paper is impermeable, but provided with ventilation openings.
- DE-PS 21 07 850 shows a filter with a cylindrical filter body with embossed, in the axial or longitudinal direction over the circumference of the filter body extending grooves, see Figures 3 and 5. It is stated in relation to Figure 5, that after a preferred embodiment, the end (51) to be attached to the tobacco rod, whereby the groove are not open to the tobacco rod side but the mouth-side end.
- This is an essential feature of the known filter, since ventilation air to enter the groove via an air-permeable shell and should reach from there to the mouth of the smoker. As a result, a dilution of the smoke with ventilation air and a reduction of the condensate content of the smoke can be achieved.
- DE-OS 27 55 720 shows a filter with a cylindrical filter body, a corrugated envelope of air-permeable filter paper and a wrapper of air-permeable paper. Between the two sheaths are channels or grooves educated. This filter body is attached to a cigarette by a ring mouthpiece or tipping paper on a tobacco rod.
- DE 31 43 964 A1 shows a similar cigarette filter with a smoke-impermeable enclosure of the filter body and with an axially extending through the filter body, central tube, which is in flow communication with the opening in the grooves. This should be the from the tobacco rod emerging smoke are divided into two parts. One part flows over the central tube and the other part flows through the filter material.
- DE 30 48 905 A1 discloses a cigarette filter with an airtight envelope for the filter core and with grooves in the circumference of the filter core, which extend over the entire length of the filter core. This filter is easier to manufacture because there is no need to change the production direction.
- a filter for tobacco smoke in the periphery of grooves are arranged, which are generated by a corrugated material around the actual filter.
- the envelope of the filter core is impermeable to smoke, the grooves being open at at least one end of the filter, the tipping paper is impermeable to smoke and has ventilation openings.
- This filter element should be versatile and flexible usable.
- GB 2 089 641 A shows a filter for a cigarette having a central, hollow tube extending into the filter material from one end of the filter.
- the filter core is surrounded by a non-porous sheath, and the filter body and the sheath have at least one groove extending longitudinally from one end of the filter body. This is intended to achieve a normal pressure drop across the cigarette for a low to moderate efficiency filter.
- GB 2 136 669 A shows a cigarette filter with a filter body which is surrounded by a smoke-permeable material.
- the filter has longitudinal corrugations that form grooves outside the smoke-permeable enclosure which are open at one end of the filter and extend longitudinally from that end to the other end, but not the entire length of the filter body.
- the serving carries Means, namely a coating rendering it impermeable to smoke over an area extending only partially over the length of the grooves and separating from the associated end of the filter a corrugated area of the enclosure which is smoke permeable.
- GB 2 095 093 A discloses a filter comprising a filter body having a non-porous sheath and grooves extending from one end of the filter a certain distance towards the other end of the filter.
- the grooves may be open to the atmosphere and oriented to extend to the mouth end of the filter or to the tobacco end of the filter. Also, the alternating arrangement of grooves that begin at the mouth end and the tobacco end is possible.
- the filter is fastened to the tobacco rod by a narrow strip of material in order to prevent disturbance of the access of the ventilation openings to the grooves.
- US-A-3,752,165 shows a filter for a smokable article with a filter body surrounded by a thin, porous wrapping paper. Multiple grooves are formed in the wrapping paper and in the filter material at one end of the filter. The grooves extend from one end of the filter to a position just before the opposite end and are surrounded by a smoke-impermeable tipping paper. The grooves extend from one end of the filter to a location spaced from the other end. This filter is intended to achieve high efficiency for the removal of the condensate from the tobacco smoke at an acceptable pressure drop.
- a filter with a filter body in the periphery of grooves are arranged, which extend from the tobacco-side end of the filter to a point in front of the mouth-side end of the filter.
- the grooves are formed in a rigid plastic envelope surrounding the filter material. At one end everyone Groove is provided an opening which allows a connection to the filter material. A filter ventilation is not provided.
- This filter is highly resistant to crushing so that the or each groove can remain open throughout the smoking of the smokable article.
- the filter achieves a nearly uniform release of particulate matter per train by a relatively steady increase in filter efficiency.
- US-A-3,596,663 shows a filter for a smokable article having a filter body with grooves whose length is not defined.
- the filter wrapper and tipping paper are each porous or perforated.
- the air-permeable envelope has a wave shape to increase its air-permeable surface area and thereby facilitate the conduction of the air admitted by the ventilated tipping paper to the filter material of the filter body. This is to provide a vented filter that significantly reduces the restriction of air passage to the filter media.
- cigarette filters have been provided with grooves which, depending on the position and the length of the grooves as well as the porosity or ventilation of the tipping paper / filter wrapping paper, permit the different guidance of smoke and / or air. Thinning of the smoke, turbulence of the smoke in the mouth, separate ventilation and smoke control, as well as some other effects can be achieved.
- the invention has for its object to provide a filter for a smokable article, in particular a cigarette, which allows an effective, in particular adjustable reduction of the CO content compared to other ingredients such as condensate / nicotine of the smoke.
- the advantages achieved by the invention are based on the fact that the filter design defined here reduces the CO content of the smoke very effectively, but hardly influences the condensate content. This filter therefore offers the possibility of influencing the CO / condensate ratio and ultimately determining it.
- the ventilation air flows when smoking the cigarette through the grooves in the direction of tobacco rod and from there back through the filter into the mouth of the smoker.
- a filter wrapping paper can be used which is inherently porous or ventilated, that is, provided with ventilation openings. Then, part of the ventilation air flows through this flow path, that is through the permeable filter wrapping paper, into the filter and to the smoker's mouth.
- This proportion can be adjusted by appropriate adjustment of the inherent or artificial porosity of the Filter wrapping papers are regulated, which in turn can be influenced on the ratio CO / condensate.
- two to ten grooves are provided because the use of only a single groove results in a very asymmetric distribution of the ventilation air in the smoke, which could affect the smoking pleasure. More than ten grooves are very expensive to manufacture and also leave little room for sufficient flow cross sections of the individual grooves. Good results were achieved with four grooves.
- the grooves have a V-shaped, or but, more preferably U-shaped cross-section, as this has manufacturing and fluidic advantages.
- filter material all conventional filter materials used in question, wherein one or more of these materials can be used.
- additives such as activated carbon or flavored additives is possible.
- a conventional filter tow of cellulose acetate is used.
- the grooves extend for less than 80% of the length of the filter, with good results being achieved at about 60%.
- the groove depth should be in the range of 1 to 2 mm, preferably about 1.5 mm, resulting in suitable flow volumes.
- the width of the grooves measured at the periphery of the filter should be between 1 and 3 mm, preferably between 1.5 and 2.5 mm.
- the tipping paper used to attach the filter to the tobacco rod may be of conventional construction, provided that it allows for ventilation. This can be done either by using a porous, so inherently air-permeable tipping paper or by the mechanical, electrostatic or laser-generated generation of ventilation openings.
- FIG 1 shows a perspective view of a portion of a generally indicated by the reference numeral 10 filter cigarette with a conventional tobacco rod 12 and attached to one end of the tobacco rod 12 filter element 14.
- the filter element 14 consists of a cylindrical filter body 16 of filter tow of cellulose acetate, the is homogeneously distributed over the entire volume of the filter body 14. So there are no flow openings, pipes, etc. provided in the filter body 14.
- the filter body 14 with the filter mass 16 is surrounded by a filter wrapping paper 18, which may be impermeable to air, depending on requirements, in particular taking into account the desired tobacco taste, inherently porous and / or provided with ventilation openings.
- grooves 20 are impressed, in the illustrated embodiment, four grooves 20 which are distributed symmetrically over the circumference of the filter body 14.
- the grooves 20 extend to the tobacco rod side end of the filter 14 and are open there, so that a flow connection between the grooves 20 and the tobacco rod 12 is.
- the grooves 20 extend over the circumference of the filter body 16 in the axial direction and terminate in a fluidically sufficient distance before the mouth end of the filter 14, ie at a distance in which neither air nor smoke from the grooves 20 directly to the mouth end of the filter body 14 can get.
- the axial length of the grooves 20 should be less than 80% of the length of the filter body 14. About 60% is preferred.
- the grooves 20 have in cross-section U-shape, a depth of about 1.5 mm and at the periphery a width of about 2 mm.
- the filter body 14 is surrounded in the usual way by a tipping paper 22, which is provided in the illustrated embodiment with two circumferential parallel rows of ventilation openings 24. Also, more or less rows of ventilation openings 24 may be provided, or the tipping paper 22 may be inherently porous. It only has to be ensured that the porosity or the number and size of the ventilation openings 22 ensure a desired degree of ventilation.
- the ventilation air flows when smoking the cigarette through the ventilation openings 24 in the grooves 20 and then in the grooves 20 in the direction of tobacco rod, where the direction is reversed and the ventilation air now together with the smoke from the tobacco rod 12th flows through the filter body 16 into the mouth of the smoker.
- the filter wrapping paper is permeable to air, ie inherently porous or provided with ventilation openings
- a regulatable proportion of the ventilation air flows through this flow path, ie through the air-permeable areas of the filter wrapping paper, into the filter and to the smoker's mouth.
- the dilution of the smoke by the ventilation air can be set in two places, namely once on the ventilation 24 of the lining paper 22 and on the other via the ventilation air, which enters the filter material 16 directly via the grooves 20.
- short grooves can be embossed only open to the mouth side of the filter 14, which have no function in terms of flow, since they are not connected to the ventilation zone 24, but only the smoker the presence of grooves in the Show filter 14.
- Figure 2 shows a graph of the effect of filter ventilation on the CO / condensate ratio in a conventional filter-tow filter of cellulose acetate, an airtight type according to the present invention
- the ventilation of the filter 14 was varied, from the filter ventilation 0 to a maximum degree of ventilation of 70%.
- the full circles indicate the measured values for a conventional filter of monoacetate filter tow without grooves, while the squares describe the measured values for a filter 14 according to the invention with the construction explained above and otherwise the same dimensions as the comparison filters.
- the filter 14 according to the invention reduces the CO content of the smoke and thus the ratio CO / condensate from about 1.4 to about 0.7, while by ventilation alone, ie without the use of grooves, the ratio CO / Condensate can only be lowered to about 1.12.
