  • the invention relates to smoking articles and, in particular, to modifying smoke in smoking articles.
  • Smoking articles comprising smoke modifying agents are known in the art.
  • Examples include absorbents or adsorbents located in the filter section or tobacco rod of the smoking article.
  • Particulate filters absorb smoke constituents residing in the particulate phase of a smoke stream.
  • Adsorbents are often included and are known to adsorb smoke constituents travelling in the vapour phase of the smoke stream. While such absorbents and adsorbents have removed smoke constituents from the smoke stream as it passes through the smoking article, the arrangement of the smoking article has not allowed the temperature profile of the smoke to be controlled. As such, smoke constituents are not removed when it is desirable that they be removed.

  • the at least one channel may comprise a plurality of channels disposed radially about the circumference of the rod of smokable material.
  • the smoke stream is cooled downstream of the first region of filtration material for example by means of a cooling chamber.
  • a region of adsorbent material may be provided in or downstream of the cooling chamber.
  • Perforations for cooling the smoke may be included in a wrapper circumscribing the filter section.
  • a diluent may be provided, for example downstream of the first region of filtration material.

  • a second region of filtration material may be provided downstream of the first region of filtration material, wherein the second region of filtration material has a filtration efficiency lower than the filtration efficiency of the first region of filtration material.
  • the first region of filtration material may have a retention value greater than 30 percent or even greater than 70 percent.
  • the smoking article may be configured such that the first region of filtration material only removes matter with boiling points of or greater than a predetermined level, for example about 250°C, 300°C, 350°C, 400°C, 450°C or 500°C.
  • a predetermined level for example about 250°C, 300°C, 350°C, 400°C, 450°C or 500°C.

  • the mouth end filter section 55 prevents the adsorbent material 50 from coming into contact with the users mouth.
  • flavourants may be included in the mouth end filter section 55. This can have the effect of counteracting any change to the taste that may be caused by the adsorbent material 50.
  • the tipping paper 25 is provided with a gap 65 along its length which allows air to permeate into the filter section 20 and some smoke constituents to permeate out of the filter section 20.

  • the smoke stream is formed from various constituents, each of which exist in a vapour phase and/or a particulate phase.
  • the amount of each smoke constituent that exists in each phase depends on the temperature of the smoke.
  • the proportion of a particular smoke constituent that exists in the vapour phase rises with rising temperature.
  • the fall in temperature of the smoke is reduced by factors such as changes in the downstream flow of the smoke.
  • the flow is affected by using short, slim tobacco rods or via channels or bores of low flow resistance in the tobacco and the use of low permeability wrappers around the tobacco rod. Additional factors such as use of thermal conducting materials and reducing the thermal mass of the tobacco rod are also important factors.
  • the smoke stream passes through the diluent holding material 35 which dilutes the smoke by adding further constituents to the smoke aerosol.
  • the diluent holding material 35 may be located either within the region of high FE material 30 or inside the cooling chamber 40.
  • the smoke cools to a lower temperature. As the smoke cools various constituents that were previously in the vapour phase condense into the particulate phase.
  • the rate at which the smoke cools will be affected by factors such as the positioning of any perforations such as gap 65 in the tipping paper 26 and the level of natural permeability of the tipping paper 25 and plugwrap 27 as the smoke is ventilated with ambient air.
  • the gaps 65 may be between 1 and 30 mm in length. It will be apparent to those skilled in the art that the choice of tipping paper 25 and plugwrap 27 is therefore important since it allows the cooling of the smoke, and the proportions of constituents residing in the vapour and particulate phases to be better controlled.
  • particulate phase constituents are removed.
  • the amount of particulate material removed from the smoke stream at the region of low FE material 45 is lower than that removed at the region of high FE material 30 due to the lower filtration efficiency of the region 45 relative to the region 30.
  • Adsorbent material 50 such as activated carbon or any other adsorbent of smoke constituents that is known in the art, may be located within the region of low FE material 45.
  • the adsorbent material 50 removes smoke constituents mainly in the vapour phase.

  • this medium FE material 85 Downstream of this medium FE material 85 there is provided a filter arrangement substantially similar to the arrangement described above with reference to Figure 1.
  • the FE of the region 85 is higher than the FE of the region 45 and lower than the FE of the region 80.
  • the centre of the annular region 80 forms a longitudinal bore 86 extending along the length of the annular region 80 which may be approximately 0.1 to 2 mm in width.
  • certain smoke constituents build up in the central bore 86, eventually at least partially blocking the bore 86 to smoke constituents.
  • the pressure drop across the filter region 80 during the first few draws will differ from that after later draws when the filter region 80 has become hot and when the tobacco rod 15 has been at least partially combusted and is therefore shorter.
  • Smoke that passes through the filter region 80 following the first few draws will therefore contain different proportions of certain smoke constituents than will smoke passing through the region 80 from later draws. This is because some smoke that is drawn through the region 80 from the earliest draws will travel through the central bore 86 and will be substantially unfiltered by the region 80. However, smoke from later draws will be forced through the filtration material located in the outer annulus of the annular region 80.
