Definitions

  • the invention relates to a filter for a smoking article and to a smoking article including a filter.
  • the filter 4 further comprises a second section 10 at the mouth-end of the filter 4 comprising fibrous filter material 11 formed into a tubular shape and having a channel 12 extending through the centre of the filter material 11.
  • the empty or hollow channel 12 extending through the centre of the filter material 11 can be from 1mm to 6mm in diameter, for instance from 2mm to 5mm in diameter.
  • the channel 12 extending through the centre of the filter material 11 is, in the present example, an empty, hollow passageway.
  • the channel in some embodiments, extends through an axial region of the filter material of the second filter section 10.
  • the axial region of the second filter section 10 is a region, in the present example, centred on the axis 'a' of the smoking article 1, having a radius of about 2.5mm.
  • the capsule 68 is located within a portion of the first filter section 66 closer to the downstream end of the first filter section 66, or to the second filter section 70, than to the upstream end of the first filter section, or to the tobacco rod 62.
  • the distance 'd' between the centre of the capsule 68 and the downstream end of the first filter section 66 is approximately 30% of the total longitudinal length of the first filter section 66.
  • the capsule 68 can be located longitudinally centrally within the first filter section 66 or closer to the upstream end of the first filter section 66 than to the downstream end.
  • FIG 7 is a schematic illustration of a smoking article 121 having a filter not falling under the scope of the present invention.
  • the features of the smoking article 121 are the same as those of the smoking article 1 described with reference to Figure 1 , unless otherwise stated below.
  • the smoking article 121 includes a tobacco rod 122 wrapped in a wrapping material 123, in this example cigarette paper, connected longitudinally to a filter 124 by tipping material 125 overlaying the filter 124 and partially overlaying the wrapping material 123.
  • the filter 124 further comprises a second section 130 at the tobacco rod end of the filter 124 rather than at the mouth end of the filter 124 comprising fibrous filter material 131 formed into a tubular shape and having a channel 132 extending through the centre of the filter material 131, or through an axial region thereof, similar to the second section 10 of the filter 4 of Figure 1 .
  • the tubular filter section is formed from cellulose acetate tow and is wrapped in a second plug wrap 133.
