Definitions

  • the present invention relates to a cigarette with a very low tar content which has an acceptable draft resistance and yet a tobacco taste equivalent to that of a conventional cigarette with a higher tar yield.
  • multi-section filters including, on the tobacco side, a section with a high filtration rate and on the mouth side, a section with low draft resistance, ventilation holes being provided at the level of the junction between the two filters.
  • the smoke passing through the section on the mouth side is diluted in the ventilation current and we therefore obtain a resistance to draft acceptable.
  • the invention therefore more particularly aims to remove these disadvantages.
  • the flow of smoke emanating from the tobacco section and which propagates in the central region of the acetate filter section will undergo at the start (i.e. during the period when the paper section distorts the taste the most) stronger flavoring (path length + heat and humidity of the flow) than that undergone by the ventilation flow whose flow is greater, the shorter flavoring route, but which initially does not taste bad.
  • the flavoring will be included in a filter section between the filter section with a high filtration coefficient and the filter section with low filtration coefficient.
  • ventilation holes will be preferably provided in the central area of the flavored filter section.
  • the cigarette consists of a non-flavored tobacco section 1, of usual dimensions, contained in an envelope of cigarette paper 2 and extended by a ventilated filter 3 with three sections T 1 to T 3 housed in a tubular cuff 4 which overlaps the tobacco section 1 so as to ensure the mechanical connection of the filter 3 / tobacco section 1.
  • the filter section T 1 located on the tobacco side, with a length of the order of 10 mm, is a paper section with very high draft resistance and filtration (RT ⁇ 150 - filtration> 80%).
  • the filter section T 3 located on the mouth side, also of the order of 10 mm in length, is a section of cellulose acetate with very low resistance to RT draft and filtration.
  • a section T 2 of 5 mm in length constituting a chamber containing an adsorbent material such as sepiolite flavored with a flavoring having a tobacco odor.
  • the ventilation of the filter 3 is ensured by means of perforations P of the cuff 4 located approximately 13 mm from the orifice of the filter T 3 located on the mouth side, that is to say at the level of the central region of the section T 2 .
  • the smoke produced by the combustion of the tobacco section 1 and whose flow is indicated diagrammatically by a hatched zone between the veins V 1 and V 2 passes mainly through the central region of the sections T 2 and T 3 , while the ventilation air flows (veins V 3 , V 4 ) which pass through the perforations P circulate in an annular zone surrounding the flow of smoke.
