Problems solved by technology

While increasing the stiffness of the mouth end of the filter prior to smoking, this does not overcome the increased risk of deformation of the mouth end cavity as the material defining the cavity becomes wet during smoking

Embodiment Construction

[0075] figure 2 and 3 A smoking article 10 according to the invention is shown. The smoking article 10 comprises a wrapper 12 of tobacco cut filler attached at one end to an axially aligned filter 14 . A strip of tipping paper 16 surrounds the filter 14 and a portion of the tobacco wrapper 12 to join the two portions of the smoking article 10 together.

[0076] Such as image 3 As shown in , the filter 14 includes a hollow tube section 24 , a first filter section 20 which may or may not contain fragrance, and a rod end filter section 18 . The upstream end of the hollow tube section 22 abuts against the downstream end of the first filter section 20 . The upstream end of the first filter section 20 abuts the downstream end of the rod end filter section 18 . The upstream end of the rod end filter segment 18 abuts against the tobacco rod 12 . The hollow pipe section is 10mm long. The first filter segment is 12mm long. The rod end filter segment is 12mm long. Overall filt...

Abstract

A smoking article (10) comprises: a tobacco rod (12); a filter (14) in axial alignment with the tobacco rod, the filter (14) comprising: a hollow tube segment (22) having a wall thickness of no more than 0.9 mm;and a filtration portion upstream of the hollow tube segment (22), the filtration portion comprising one or more filter segments (18) (20). The hollow tube segment (22) defines a cavity (26) at the mouth end of the filter (14) providing an unrestricted flow channel that extends from the downstream end of the filtration portion to the mouth end of the filter (14). The hollow tube segment(22) is formed from a fibrous filtration material and comprises a filter plasticiser, wherein the amount of filter plasticiser is at least 22 percent by weight of the fibrous filtration material.

Description

technical field [0001] The present invention relates to a smoking article having an orifice cavity defined by a hollow tube section. [0002] Filter cigarettes generally comprise a cylindrical rod of tobacco cut filler surrounded by a wrapper, and a cylindrical filter axially aligned in abutting end-to-end relationship with the wrapped tobacco rod. Cylindrical filters generally consist of a filter material surrounded by plug paper. Conventionally, the packaged tobacco rod and filter are joined by a strip of tipping paper, usually formed of opaque paper material, which surrounds the entire length of the filter and adjacent portions of the packaged tobacco rod. The invention also proposes a smoking article having a cavity at the mouth end of its filter section. Background technique [0003] Various smoking articles in which tobacco is heated rather than combusted have been proposed in the art. In heated smoking articles, an aerosol is generated by heating an aerosol-generat...
