Definitions

  • hyperlighter cigarettes having a tar content of the order of 0.5 and 1 mg and a draft resistance (RT) greater than 65 mm of EC, preferably close to 90 mm of CE, and delivering a primary smoke having an aromatic character considered equivalent to earlier products having a much higher tar content.
  • RT draft resistance
  • the object of the invention is to achieve the objectives set out above while avoiding the drawbacks of all these known solutions.
  • the cigarette consists of a cylindrical tobacco section T 1 housed in a paper envelope E 1 , of a filter whose two sections T 2 , T 3 are axially contiguous, of a flavored thick cladding G 1 which surrounds the filter section T 3 located on the mouth side, an assembly cladding G 2 of the two filter sections T 2 , T 3 and a microperforated assembly sleeve M 1 , of the filter on the tobacco section T 1 .
  • the filter section T 3 located on the mouth side is made of cellulose acetate or an equivalent product preferably of low resistance to draft, for example of the order of 15 to 20 mm of CE, and of negligible tar retention. This resistance to draft could however be increased up to 30 mm of CE.
  • the filter section T 2 located on the tobacco side which can be produced from paper has, for its part, a high resistance to draft, for example of the order of 110 to 180 mm of EC, (preferably 150 for a cigarette of 0, 5 and 130 for a 1 mg cigarette) and is highly retentive in tar: tar retention could drop to 65% for a 1 mg cigarette but would preferably be greater than 80% for a 0.5 mg cigarette.
  • the assembly cladding G 2 of the two filter sections T 2 , T 3 can be of the same nature as the cladding G 1 . It can also be loaded with aromatic compounds.
  • the cuff M 1 is a conventional perforated or porous assembly cuff giving ventilation of the cigarette of the order of 60 to 80%, preferably of the order of 72% for a cigarette of 0.5 mg and 65 % for a 1 mg cigarette, the perforations P being located in an area located substantially at the junction between the two sections T 2 , T 3 (for example 13 mm from the end of the cigarette, mouth side) .
  • the invention is not limited to the embodiment described above.
  • two flavored cladding G 1 , G 2 which can be impregnated with two respective sets of different aromatic compounds whose different partial adsorption on paper and acetate would modify the perception by the smoker.
  • adsorbents such as, for example, carbon into the paper filter part. active, either in the paper matrix, or during the manufacture of the filtering section by welding, or even gluing.
