Definitions

  • Popular smoking articles such as cigarettes, have a substantially cylindrical rod shaped structure and include a charge, roll or column of smokable material such as shredded tobacco (e.g., in cut filler form) surrounded by a paper wrapper thereby forming a so-called "tobacco rod.”
  • a cigarette has a cylindrical filter element aligned in an end-to-end relationship with the tobacco rod.
  • a filter element includes cellulose acetate tow circumscribed by plug wrap, and is attached to the tobacco rod using a circumscribing tipping material. It also has become desirable to perforate the tipping material and plug wrap, in order to provide dilution of drawn mainstream smoke with ambient air.
  • smokable material 20 is contained in a first circumscribing inner wrapping material 25, and a second outer wrapping material 27 circumscribes the first wrapping material.
  • the first wrapping material 25 is formed into a circular shape such that the ends 71, 72 of the sides thereof abut one another.
  • the ends 71, 72 of wrapping material 25 can abut one another (as shown in Figure 1A), nearly abut one another, or slightly overlap one another.
  • the second wrapping material 27 includes a lap zone 73 including a suitable adhesive therebetween so as to form a secure outer wrapper.
  • the width of the inner wrapping material is less than that of the outer wrapping material.
  • Another wrapping material is available as P-3122-4-4 from Kimberly-Clark Corp.; which is a paper made from about 20 weight percent wood pulp, about 30 weight percent Turkish tobacco strip, about 30 weight percent "American blend” in cut filler form and about 20 weight percent calcium carbonate particles, and is electrostatically perforated to a net permeability of about 150 CORESTA units.
  • Another wrapping material is available as P-2831-189-AA4 from Kimberly-Clark Corp.; which is a paper made from 20 weight percent wood pulp, about 30 weight percent Turkish tobacco strip, about 30 weight percent "American blend” in cut filler form and about 20 weight percent calcium carbonate particles, and has a basis weight of about 60 g/m 2 and an inherent permeability of about 125 CORESTA units.
  • Cigarettes of the present invention exhibit a desirably high resistance to draw.
  • cigarettes of this invention exhibit a pressure drop of between about 50 and about 200 mm water pressure drop at 17.5 cc/sec. air flow.
  • pressure drop values of cigarettes are measured using a Filtrona Filter Test Station (CTS Series) available from Filtrona Instruments and Automation Ltd.
  • Cigarettes of this invention preferably exhibit resistance to draw values of about 70 to about 180, more preferably about 80 to about 150 mm water pressure drop at 17.5 cc/sec. air flow.
  • the solution is applied to the paper wrap by immersing the wrap in the solution at ambient temperature so as to saturate that paper with the solution.
  • the paper is removed from the solution, pressed to remove excess solution, dried at about 80°C to about 90°C on a curved top sheet dryer, and conditioned under ambient conditions for about 4 hours. After conditioning, the paper exhibits a basis weight of 33 g/m 2 and a porosity of 7.9 CORESTA units.
  • the final outer wrap includes about 75 parts calcium carbonate, wood pulp and flax fiber; and about 25 parts of a mixture of calcium, acetate, potassium and chloride ions provided by the additive package.
  • the cigarettes are smoked and tested as described in Example 1, and yield 10.7 puffs and yield a sidestream absorbance value of 0.1972.
  • the exemplary cigarette having the treated wrapping material and a comparison cigarette are treated for sidestream smoke production using the techniques described in Example 1.
  • the sidestream smoke absorbance value for the comparison cigarette is 0.6716, while that for the exemplary cigarette is 0.5243.
