Definitions

  • the invention relates to a cigarette, in particular filter cigarette, cigarette paper, in particular filter cigarette tube, each with a ventilation zone according to the preamble of claim 1, and a method for producing such a cigarette or cigarette paper tube.
  • the cigarette industry is increasingly launching cigarette brands that have a relatively low nicotine and condensate content in the smoke.
  • the aim of the invention is now to exploit the possibilities of influencing smoke, which result from the admixture of ventilation air in the filter. This should significantly reduce the condensate, nicotine and carbon monoxide content in the smoke.
  • the focus of the task is to provide a predetermined or controlled admixture of secondary air with the simplest means, ie. H. with the least possible effort.
  • the optical appearance of the correspondingly prepared filter cigarette or filter cigarette tube should remain unchanged. d. H. correspond to conventional filter cigarettes or filter cigarette tubes.
  • the essence of the present invention therefore lies in the fact that the filter cigarette or filter cigarette sleeve is mechanically perforated in each case before attachment of the tip paper in the filter area, with the formation of air passage openings or holes.
  • the ventilation zone defined by the pierced openings with porous covering paper does not have to be given particular attention to the highest dimensional accuracy and optically good appearance of the air passage openings when they are manufactured. So a relatively rough perforation is enough.
  • the degree of ventilation which is determined by the ratio of the admixed fresh air component to the total waste stream, is essentially defined by the porosity of the tip paper. For this reason, a complex and expensive laser perforation of the filter area of a filter cigarette or filter cigarette sleeve, as is currently being used increasingly, can be dispensed with when the invention is used.
  • the ventilated filter cigarette or filter cigarette tube ensures not only a reduction in pollutant values, but also a considerably greater taste uniformity.
  • the optical appearance of the filter cigarette or filter cigarette tube prepared according to the invention does not differ from conventional products of this type.
  • the air passage openings can be produced in the conventional mechanical rolling process. Accordingly, it is not very expensive.
  • the highest shape and diameter accuracy of the air passage openings is not important in the invention, since the degree of ventilation is ultimately determined by the porosity of the tip paper covering the filter. The same applies to the visual appearance.
  • the filter cigarette shown schematically in FIG. 1 consists of a tobacco rod 12 covered with cigarette paper 10, which is attached to one of the two end faces of a filter 14.
  • the filter 14 is coated with a filter wrapping paper 16.
  • the connection between filter 14 including filter wrapping paper 16 and Tobacco strand 12 wrapped with cigarette paper 10 takes place by means of a mouthpiece covering paper 18 which extends in the axial direction over the area of the filter and an adjoining section 20 of the tobacco strand 12 wrapped with cigarette paper 10.
  • the covering paper 18 is glued to the two parts of the filter cigarette mentioned.
  • the air-impermeable filter wrapping paper 16 is provided with air passage openings or holes 24 which are arranged approximately uniformly over the circumference.
  • the air passage openings 24 are pierced by means of a needle or a needle cushion in a manner described in more detail below. These air passage openings 24 are covered by the highly porous or perforated covering paper 18 and are therefore not visible from the outside.
  • the number of air passage openings 24 distributed over the circumference fluctuates between 4 and 40.
  • the mean diameter of the air passage openings 24 is between about 0.05 and about 0.4 mm, the size of the diameter preferably being inversely proportional to the number of air passage openings.
  • the axial distance of the air passage openings 24 from the free end of the filter area is approximately 12 to 30 mm, depending on the length of the filter 14.
  • Two or more circumferential rows of air passage openings 24 arranged axially apart from one another can be provided, with diameter and / or The number of air passage openings per circumferential row can be dimensioned differently.
  • a filter cigarette shown schematically in FIG. 1, is produced in such a way that first a double filter coated with air-impermeable filter wrapping paper 16 is pierced by means of a needle or a needle cushion to form the air passage openings 24, and then inserted into the two end faces of the double filter in a manner known per se attached to cigarette paper 10 wrapped tobacco rod 12, this fixed to the double filter by means of the porous covering paper 18 enveloping the double filter, and finally the "double cigarette” thus produced is separated into two single cigarettes in the area of the double filter according to FIG. 1.
  • FIG. 8 schematically shows a device for producing the air passage openings as part of an ongoing manufacturing process.
  • This device comprises a roller drum 28 rotating in the direction of arrow 26, which has troughs 30 arranged uniformly distributed on the outer circumference for receiving a double filter or a filter cigarette sleeve, these troughs 30 being assigned a pin cushion 34 rotating in the direction of arrow 32.
  • the pincushion rotates in the opposite direction to the roller drum 28.
  • the individual perforation needles are indicated in FIG.
  • the filter area to be perforated is identified by the reference number 14 'and an already perforated filter area is identified by the reference number 14 ".
  • the axial assignment of the needles 36 to the filters to be perforated is selected such that the air passage openings 24 are located from the free end of the filter 14 have an axial distance of about 15 to 25 mm corresponding to the selected length of the filter 14.
  • FIG. 2 shows a filter cigarette tube which comprises a filter 14 coated with filter wrapping paper 16 and cigarette paper 10.
  • the filter wrapping paper 16 and the cigarette paper 10 as well as any glue layers are pierced or perforated with the formation of air passage openings 24 which are evenly distributed over the circumference, the needle perforation as above using the 8 can be described.
  • the filter area is covered by a highly porous or finely perforated tipping paper 18, giving the impression of a conventional filter cigarette tube.
  • the degree of ventilation is therefore essentially determined by the porosity of the covering paper 18.
  • the air permeability of the air passage openings 24 as a whole is greater than the specific air permeability of the covering paper 18.
  • the porosity of the covering paper 18 to be selected is also determined by the number and diameter of the air passage openings 24.
  • the air passage openings 24 can be pierced at least partially obliquely to the radial and / or the axial longitudinal direction in order to achieve the effect described above with the aid of a filter cigarette.
  • two or more circumferential rows of air passage openings 24 can also be provided in the filter cigarette sleeve according to FIG. 2, the diameter and / or number of the air passage openings per circumferential row being dimensioned differently.
  • Fig. 4 shows that the degree of ventilation V q (%) also increases with increasing resistance R1 (mbar).
  • Train resistance fluctuations of z. B. 5.3 to 9.5 millibars increase the degree of ventilation from 37 to 42%.
  • fluctuations in train resistance can arise from the use of fluctuating quantities of smoking tobacco.
  • the use of a little more tobacco leads to more nicotine, condensate and carbon monoxide, but also increases the draft resistance in the tobacco rod. This reduces the main smoke flow and inevitably increases the degree of ventilation.
  • the result is a greater dilution of the total smoke and compensation for the larger amount of tobacco smoke components present in this case, such as nicotine, condensate and carbon monoxide.
  • the degree of ventilation in the same ventilation zone can still be influenced by the amount of tobacco, the tobacco cut, the tobacco moisture and also the porosity of the cigarette paper. These parameters also influence the main smoke flow. Despite this physical dependency, the effect of ventilation is clearly noticeable, as can be seen in FIGS. 4 to 7.
  • a filter cigarette tube can also be produced without filter wrapping paper 16 (see FIG. 3). In this Case, of course, only the cigarette paper 10 enveloping the filter 14 is pierced to form the ventilation zone 22.
