There is also at least one perforation in the area of the groove for introduction provided by air through the envelope in the filter body. This is supposed to a filter is provided with an improved air distribution in the filter rod become.
  • An envelope made of impermeable material contributes to this air-permeable area.
  • the covering paper is impermeable, but provided with ventilation openings.
  • DE-PS 21 07 850 shows a filter mouthpiece, the scope is provided with longitudinal grooves.
  • a filter wrapping paper is not mentioned and the grooves are preferably open towards the mouth end of the filter.
  • DE 31 43 965 C2 shows a cigarette filter with grooves that are neither open to the tobacco nor to the mouth end, so only about the Extend the center of the filter body.
  • Each groove has an opening so that ventilation air in the longitudinal direction of the filter rod towards the Mouth end is steered. This is supposed to easily provide high outside air Speed can be inserted into the cigarette filter without the There is a risk of closing due to lip pressure or pressure drop.
  • DE 31 43 964 A1 shows a similar cigarette filter with a smoke-proof covering of the filter body and with an axially through the filter body extending central tube, which in Flow connection with the opening in the grooves is. This is supposed to smoke emerging from the tobacco rod can be divided into two parts. On Part flows over the central tube and the other part flows through the Filter material.
  • DE 30 48 905 A1 describes a cigarette filter with a air-impermeable covering for the filter core and with grooves in the Extent of the filter core that extends over the entire length of the filter core extend. This filter is easier to manufacture because one Change of production direction is omitted.
  • a filter for tobacco smoke is known from DE 32 25 091 C2, in which Perimeter grooves are arranged through a corrugated material around the actual filters are generated.
  • the envelope of the filter core is smoke-tight, with the grooves on at least one end of the filter are open, the covering paper is smoke-proof and shows Ventilation openings.
  • This filter element is said to be versatile and flexible be usable.
  • GB 2 089 641 A shows a filter for a cigarette with a central, hollow tube that extends from one end of the filter into the filter material extends into it.
  • the filter core is of a non-porous coating surrounded, and the filter body and the casing have at least one Groove extending longitudinally from one end of the filter body. This is supposed to include a normal pressure drop across the cigarette for a filter low to moderate efficiency can be achieved.
  • GB 2 136 669 A also shows a cigarette filter with a Filter body, which is surrounded by a smoke-permeable material.
  • the Filter has longitudinal undulations that are outside the smoke permeable Envelope form grooves that are open at one end of the filter and located in Extend longitudinally from this end to the other end, however not over the entire length of the filter body.
  • the wrapper is wearing Means, namely a coating that covers an area that is only partially extends over the length of the grooves, make smoke-tight and a corrugated area from the associated end of the filter Remove the wrapping that is permeable to smoke.
  • GB 2 095 093 A also includes a filter with a filter body a non-porous coating and with grooves that are different from one End of the filter from a certain distance towards the other Extend the end of the filter.
  • the grooves can be open to the atmosphere and be aligned so that it extends to the mouth end of the filter or to the Extend the tobacco end of the filter.
  • the alternating arrangement of Grooves that start at the mouth end and at the tobacco end possible.
  • the filter is replaced by a narrow strip of material String of tobacco attached to a disruption of access to the Exclude ventilation openings to the grooves.
  • US-A-3,752,165 also shows a filter for a smokable article with a filter body covered by a thin, porous wrapping paper is surrounded.
  • Several grooves are in the wrapping paper and that Filter material molded into one end of the filter.
  • the grooves extend from one end of the filter to a point just before opposite end and are smoke-tight Surround covering paper.
  • the grooves extend from one end of the filter to a point that is at a distance from the other end.
  • US-A-3,910,288 is a filter with a filter body known, in the circumference of which grooves are arranged, which differ from tobacco-side end of the filter up to a place in front of the mouth-side Extend the end of the filter.
  • the grooves are in a rigid plastic covering trained, which surrounds the filter material. At one end everyone Groove is provided an opening that connects to the filter material allows. Filter ventilation is not provided.
  • This filter is very resistant to crushing, so that the or each groove is open throughout the smoking of the smokable item can stay. Due to the gradual change in the proportion of smoke caused by the Groove flows from a previously defined value to 0 the filter delivers an almost uniform delivery of particulate matter per train due to a relatively steady increase in filter efficiency.
  • US-A-3,596,663 shows a filter for a smokable article with a filter body with grooves, the length of which is not defined.
  • the Filter cover and the covering paper are each porous or with Perforations.
  • the breathable wrap has a wave shape to make it breathable To increase surface area and thus direct the air to it simplify the through the ventilated covering paper to the filter material of the Filter body is approved. This is to create a ventilated filter the restriction of air passage to the filter medium significantly decreased.
  • Cigarette filters are grooved depending on the location and the length of the grooves and the porosity or ventilation of the Base paper / filter wrapping paper the different leadership of Allow smoke and / or air. Thinning of the smoke, a swirling of the smoke in the mouth, the separate guidance of Ventilation air and smoke as well as some other effects can be achieved.
  • CO carbon monoxide
  • the invention has for its object a filter for a smokable Creating articles, especially a cigarette, that are effective, in particular adjustable reduction in the CO content compared to other ingredients such as smoke condensate / nicotine.
  • a filter wrapping paper can also be used that are inherently porous or ventilated, i.e. with ventilation openings is provided. Then part of the ventilation air flows through it Flow path, i.e. through the permeable filter wrapping paper, into the Filters and to the smoker's mouth.
  • This share can be made by appropriate Adjustment of the inherent or artificial porosity of the Filter wrapping paper are regulated, which in turn affects the CO / condensate ratio can be taken.
  • two to ten grooves provided because the use of only a single groove to a very asymmetrical distribution of ventilation air in the smoke that leads to the Smoking could impair. More than ten grooves are in the Manufacturing very complex and leave little space for sufficient Flow cross sections of the individual grooves. Good results have been made with reached four grooves.
  • the rollers have a V-shaped or, particularly preferably, U-shaped Cross-section as this has manufacturing and fluidic advantages Has.
  • All conventionally used filter materials come as filter material in question, using one or more of these materials can.
  • additives such as activated carbon or Flavor-modified additives are possible.
  • the grooves extend over less than 80% of the length of the filter, with good results at around 60% were achieved.
  • the groove depth should be in the range of 1 to 2 mm, preferably around 1.5 mm lie, which results in suitable flow volumes.
  • the width of the grooves measured on the circumference of the filter, are between 1 and 3 mm, preferred between 1.5 and 2.5 mm.
  • the topping paper used to attach the filter to the tobacco rod can have a common structure, provided it leaves ventilation to. This can be done either by using a porous, ie inherently air-permeable covering paper or by mechanical, electrostatic or generation of ventilation openings produced by laser beams happen.
  • FIG 1 shows a perspective view of part of a generally through the reference number 10 indicated filter cigarette with a usual Tobacco rod 12 and one attached to one end of the tobacco rod 12 Filter element 14.
  • the filter element 14 consists of a cylindrical Filter body 16 made of filter tow made of cellulose acetate, which is homogeneous over the entire volume of the filter body 14 is distributed. So they are not Flow openings, pipes, etc. are provided in the filter body 14.
  • the filter body 14 with the filter mass 16 is one Surround the filter wrapping paper 18, depending on the requirements, that is especially considering the desired tobacco taste impermeable to air, inherently porous and / or with ventilation openings can be provided.
  • Grooves 20 are embossed into the circumference of the filter body 14 embodiment shown four grooves 20 which are symmetrical about the Scope of the filter body 14 are distributed.
  • the grooves 20 extend through to the tobacco rod end of the filter 14 and are open there, so that a flow connection between the grooves 20 and the tobacco rod 12 consists.
  • the grooves 20 extend axially over the circumference of the filter body 16 Direction and end at a fluidically sufficient distance in front of the mouth end of the filter 14, that is at a distance in which neither air nor smoke from the grooves 20 directly to the mouth end of the filter body 14 can reach.
  • the axial length of the grooves 20 is less than 80% of the length of the filter body 14 should be. To be favoured about 60%.
  • the grooves 20 have a U-shaped cross section, a depth of approximately 1.5 mm and a width of about 2 mm at the circumference.
  • the filter body 14 is covered in the usual manner by a covering paper 22 surround that in the illustrated embodiment with two revolving parallel rows of ventilation openings 24 is provided. It can more or fewer rows of ventilation openings 24 are also provided or the tipping paper 22 may be inherently porous. It just has to ensure 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 into the grooves 20 and then in the Grooves 20 towards the tobacco rod, where the direction is reversed and the Ventilation air now together with the smoke from the tobacco rod 12 flows through the filter body 16 into the mouth of the smoker.
  • the filter wrapping paper permeable to air i.e. inherently porous or with Provide ventilation openings, so an adjustable portion of the flows Ventilation air through this flow path, i.e. through the air-permeable Place the filter wrapping paper in the filter and to the mouth of the Smoker.
  • the thinning of the smoke can be carried out set the ventilation air at two points, namely once at the Ventilation 24 of the topping paper 22 and the other on the Ventilation air that enters filter material 16 directly via grooves 20.
  • Figure 2 shows a graph of the effect of filter ventilation on the CO / condensate ratio in a filter according to the invention conventional filter tow made of cellulose acetate, an air impermeable Filter wrapping paper and four grooves 20 having the above dimensions are distributed symmetrically over the circumference of the filter body 16 and starting from the tobacco-side end, over 60% of the length of the filter 14 extend.
  • the ventilation of the filter 14 was varied, namely from that Filter ventilation 0 to a maximum ventilation level of 70%.
  • the filter 14 according to the invention has a CO content of smoke and thus the ratio of CO / condensate of about 1.4 reduced to about 0.7 while by ventilation alone, i.e. without Using grooves, the CO / condensate ratio is only about 1.12 can be lowered.
