Definitions

  • the present invention relates to smoking articles such as cigarettes which are in part constructed by the smoker.
  • Hand rolled cigarettes in which a smoker wraps tobacco in a paper wrapper with or without a hand operated machine to make a cigarette, are well known.
  • rods of tobacco wrapped in very porous paper have been supplied for use with empty paper sleeves carrying filters. The rods of tobacco cannot be smoked alone, since the wrapper is too porous. The smoker inserts the wrapped rod into the open end of the sleeve to make a filter cigarette.
  • the sleeves being of ordinary tobacco wrapping paper and having a relatively long unsupported empty portion, are thin and easily damaged. Even when the sleeve is not damaged, it can be difficult to insert the tobacco rod into the sleeve.
  • a rod of smoking material comprising a wrapped column of smoking material, the wrapper of which extends beyond one end of the column to define a cylindrical cavity for the reception of a filter plug.
  • the cavity wall is constructed to collapse if a smoker attempts to draw on the rod through the empty cavity. This can be achieved by an appropriate choice of material and thickness of material for the cavity wall.
  • a rod of smoking material comprising a wrapped column of smoking material having at one end a cylindrical cavity for the reception of a filter plug, the wall of the cavity being constructed to collapse under the pressure exerted by the mouth of a smoker.
  • the cavity is formed by an extension of the column wrapper beyond one end of the column.
  • the cavity is circumscribed by tipping material, which is preferably unsmokeable.
  • Preferred tipping material include paper and plastics materials.
  • the tipping may extend beyond the mouth end of the cavity.
  • the invention also contemplates a kit for making a smoking article comprising a rod having a cavity for the reception of a filter plug and, separately, a filter plug.
  • the filter plug of the kit may be of any design and material compatible with the requirement that it can be inserted in the cavity in the rod.
  • the filter may be of cellulose acetate or paper or a combination thereof, and the plug may have a permeable or impermeable surface.
  • the plug may be grooved or of the plug-space-plug configuration, or may be a so-called concentric filter plug having a central core of different filter efficiency from an annular outer layer of filter material.
  • the plug may be the same length as the cavity in the rod, or may be shorter.
  • the wall of the cavity in the rod may be permeable or impermeable.
  • the internal surface of the cavity wall may be provided with ridges which, together with the surface of the filter plug when it is inserted, form channels of ambient air.
  • Conventional cigarettes including filters of this type are disclosed in EP-A-0 059 040 and EP-A-0 059 042.
  • a particular advantage of the present invention is that in some countries the sale of cigarette components in an unsmokeable form attracts a much lower excise duty than the sale of complete, smokeable cigarettes.
  • Figures 1 and 2 show a rod 10 and a filter plug 12.
  • the plug 12 is a cellulose acetate tow plug having a permeable surface, and is of conventional length.
  • the rod 10 comprises a column 14 of tobacco circumscribed by wrapping 16. The wrapping 16 extends beyond the mouth end of the tobacco column 14 to define a cavity 18.
  • the tobacco column 14 is of conventional length, and the cavity 18 is of the same length as the filter plug 12.
  • the cavity 18 is circumscribed by tipping material 20, which extends a little way along the wrapped tobacco column 14.
  • the cavity wall, formed of the tipping material 20 and the wrapping 16, is rendered permeable by a line 22 of perforations. These allow ambient air through the cavity wall and into the filter plug 12 when it is in the cavity 18.
  • the tipping material 20 is of an unsmokeable plastics material.
  • the cavity wall is sufficiently weak that if a smoker attempts to smoke the rod 10 without a filter in the cavity 18, the cavity wall will collapse. Since the tipping material 20 is unsmokeable, a smoker attempting to smoke the rod 10 by lighting the tipping material and drawing on the end of the tobacco column 14 will be unable to do so.
  • a smoker inserts a filter plug 12 into the cavity 18 in the rod 10.
  • the plug is held in the cavity by friction, and the resulting cigarette can be smoked normally.
  • the rods 10 and the filter plugs 12 will be sold separately. It is envisioned that a smoker will keep several different types of filter plug having different efficiencies, degrees of ventilation and even flavouring for use with one type of tobacco rod. Thus the smoker can choose the organoleptic properties of the cigarette without the need to buy several different packs of cigarettes.
