Definitions

  • the present invention relates to a smoking article including a wrapper forming a mouth end cavity.
  • filter cigarettes typically comprise a rod of tobacco cut filler surrounded by a paper wrapper and a mouthpiece axially aligned in an abutting end-to-end relationship with the wrapped tobacco rod.
  • the mouthpiece typically comprises a segment of filtration material circumscribed by a paper plug wrap.
  • Smoking articles having a cavity at the mouth end of their mouthpiece section have also been proposed.
  • the wrapped tobacco rod and the mouthpiece are joined by a band of tipping wrapper, normally formed of a paper material that circumscribes the entire length of the mouthpiece and an adjacent portion of the wrapped tobacco rod.
  • a filter cigarette is employed by a consumer by lighting the tobacco rod end thereof to burn the shredded tobacco rod. The consumer receives mainstream smoke by drawing on the mouth end of the cigarette.
  • a number of smoking articles in which tobacco is heated rather than combusted have also been proposed in the art.
  • heated smoking articles an aerosol is generated by heating an aerosol generating substrate, such as tobacco.
  • Known heated smoking articles include, for example, smoking articles in which an aerosol is generated by electrical heating or by the transfer of heat from a combustible fuel element or heat source to an aerosol forming substrate.
  • volatile compounds are released from the aerosol forming substrate by heat transfer from the heat source and entrained in air drawn through the smoking article. As the released compounds cool they condense to form an aerosol that is inhaled by the consumer.
  • smoking articles in which a nicotine-containing aerosol is generated from a tobacco material, tobacco extract or other nicotine source, without combustion and in some cases without heating, for example through a chemical reaction.
  • a smoking article comprising an aerosol generating substrate and a mouthpiece in axial alignment with the aerosol generating substrate.
  • the mouthpiece has a rod end adjacent the aerosol generating substrate and a mouth end opposite the rod end.
  • the mouthpiece comprises at least a tubular element defining a mouth end cavity.
  • the mouthpiece comprises a first wrapper circumscribing the tubular element around at least the mouth end cavity, and one or more holes are provided in the tubular element at the mouth end cavity to expose one or more portions of the inner surface of first wrapper to the mouth end cavity.
  • a method for the manufacture of a mouthpiece for a smoking article comprises providing a first wrapper web material and a second wrapper web material and forming in a first portion of the first wrapper web material one or more holes. Further, the method comprises providing two mouthpiece segments and disposing the mouthpiece segments on the first wrapper web material so that the mouthpiece segments are spaced apart with the first portion of the first wrapper web material between the mouthpiece segments.
  • the first wrapper web material is wrapped around a portion of the mouthpiece segments such that the wrapper web material forms a tubular element defining a cavity between the aligned mouthpieces segments, with the one or more holes disposed at a position along the cavity.
  • the second wrapper web material is wrapped at least around the first portion of the first wrapper web material with the one or more holes, so that one or more portions of the inner surface of second wrapper web material are exposed to the cavity.
  • upstream and downstream are used to describe the relative positions of elements, or portions of elements, of the smoking article in relation to the direction in which a consumer draws on the smoking article during use thereof.
  • Smoking articles as described herein comprise a downstream end and an opposed upstream end. In use, a consumer draws on the downstream end of the smoking article.
  • the downstream end which is also described as the mouth end, is downstream of the upstream end, which may also be described as the distal end.
  • imperforate is used to describe a portion of an element of the smoking article that has no hole, opening or aperture.
  • the continuity of the material forming an element of the smoking article is not interrupted at least over the whole of an imperforate portion of said element.
  • the mouthpiece comprises a tubular element and a first wrapper.
  • the tubular element defines a mouth end cavity.
  • the first wrapper surrounds at least the portion of the tubular element defining the mouth end cavity.
  • one or more holes are provided in the tubular element at the mouth end cavity, so that one or more portions of the inner surface of the first wrapper are exposed to the mouth end cavity of the smoking article.
  • the inner surface of the mouth end cavity provides a novel tactile perception to the consumer.
  • the holes in the tubular element provide a novel way of presenting indicia or visual content to the consumer, since they can be arranged to form text, shapes, images, logos, patterns or the like. This can advantageously result in interesting, novel ways of displaying information to the consumer and in an unusual visual impact and provides a distinctive product.
  • the holes in the tubular element may advantageously provide a novel way of marking and authenticating smoking articles so that it can be checked that they have originated from a genuine source and are not a counterfeit product.
  • the holes in the tubular element may be arranged to form an identification code which may be associated with information regarding production, and can be used to authenticate the smoking articles.
  • smoking articles according to the invention can advantageously be produced using existing apparatus and methods, optionally with the inclusion of means for registering the position of the hole(s) in the first wrapper relative to the other components of the smoking article.
  • Smoking articles according to the present invention may be filter cigarettes or other smoking articles in which the tobacco material is combusted to form smoke.
  • smoking articles according to the present invention may be articles in which the tobacco material is heated to form an aerosol, rather than combusted.
  • the tobacco material is heated by one or more electrical heating elements to produce an aerosol.
  • an aerosol is produced by the transfer of heat from a combustible or chemical heat source to a physically separate tobacco material, which may be located within, around or downstream of the heat source.
  • the present invention further encompasses smoking articles in which a nicotine-containing aerosol is generated from a tobacco material without combustion or heating.
