Definitions
- the present invention relates to filter cigarettes having improved smoke characteristics.
- One measure adopted to reduce the weight of tobacco is that of reducing the density of the filler.
- Another measure which results in a reduction in the weight of tobacco is that of reducing one or more dimensions of the cigarette. This has been done, for example, by reducing the diameter to 5-7.5 mm while maintaining the length, as in “slim” cigarettes or by reducing both the length and diameter to 65-80 mm and 7-7.4 mm respectively, as in certain "economy” cigarettes, whereby the volume of tobacco is decreased while the density remains within conventional values.
- the cigarettes in accordance with the present invention are characterised by a total length of 50 to 70 mm, a filter length of 19 to 28 mm and a tobacco density of 270 to 320 mg/cm3, preferably 290 to 300 mg/cm3.
- the preferred cigarettes have diameters from 7.0 to 8.3mm, exhibit an overall resistance to draw of 120 to 170 mm of water and a puff count (under standard conditions) of 5 to 7.
- the nature and characteristics of the filter material are not critical, and conventional filter rods can be used.
- the cigarettes according to the invention yield substantially less sidestream smoke components than conventional cigarettes with similar delivery to the smoker and, for example, can deliver up to 40% less particulate matter to the sidestream than conventional cigarettes.
- the visibility of the sidestream is reduced correspondingly.
- the cigarettes according to the invention use substantially less tobacco than conventional cigarettes of similar mainstream smoke delivery, while affording a smaller number of puffs, they are eminently suitable for consumption by smokers having limited smoking time at their disposal, while obtaining the benefits of strong flavour and delivery per puff. At the same time they improve the quality of the environment by a reduction in the sidestream smoke delivery.
- FIG. 1 and 2 illustrate by way of example only, cigarettes according to this invention respectively without and with perforations in the filter region for the admission of ventilating air.
- the cigarette of Fig. 1 comprises a wrapped tobacco rod 1 and an abutting filter 2, interconnected by a tipping wrapper 3, the cigarette having the dimensions and other parameters characteristic of the invention.
- the cigarette of Fig. 2 is similar to that of Fig. 1 with the exception that means are provided for the admission of a desired proportion of air to dilute the smoke drawn into the mouth of the smoker.
- these means take the form of an annular zone of perforations 4 in the tipping material 3, the filter 2 (whether wrapped or otherwise) having an air-permeable peripheral wall.
- Table 2 sets out the mainstream smoke delivery values for these two cigarettes, while Table 3 sets out the sidestream smoke parameter values for the same two cigarettes.
