Definitions

  • This invention relates generally to cigarette filters and, particularly, to cigarette filters including materials which sequester, retain or remove tars from the stream of gases drawn through a cigarette, by the smoker, so that they do not emerge from the tip.
  • FIGURE 1 is a vertical sectional view of one form of a filter cigarette including a filtration material
  • kelp has the capacity to sequester, retain or otherwise remove tars from the stream of warmed air emanating from the tip, when a cigarette is smoked.
  • Kelp belongs to the group of plants known as algae. They range from the microscopic denizens of the sea to the giant kelp plants, whose fronds may attain lengths of over 600 feet.
  • the types of kelp generally referred to herein are the large brown seaweeds of the family lammariaceae and fucaceae. It has been found that these weeds may be dried, and reduced to a fine, greyish-green powder.
  • Kelp as used herein refers to those seaweeds. It does not refer to the ash-residue obtained from burning kelp. In accordance with Websters New International Dictionary, Second Edition, Unabridged (1954 copyright), at page 2011, pulverulent as used herein means consisting of, or reducible to fine powder.
  • a cigarette 11 of ordinary character is prepared: a paper cylinder, stuffed with shreads of tobacco 12.
  • Numerous types of filtration materials are today well known. Probably the oldest is cotton. All filtration materials are generally characterised by their ability to be penetrated by gaseous matter, to which they offer little resistance. Some filtration materials, offering greater resistance to penetration by gaseous matter, are less suitable because they lack draw quality, or modify the draw quality of the ordinary unfiltered cigarette: the capacity to easily pass the warmed air sucked through the filter by the smoker. While filtration materials will be referred to, the function of the material is not to filter, but only to retain the kelp, rather than filter the combustion material, from being sucked into the mouth of the smoker, and to hold it in place.
  • the filtration material is formed into a wad 13 or section having a cross-sectional configuration conforming to that of the cigarette.
  • the wad may be approximately /8 inch long and placed at the end 14 of the cigarette.
  • a thin layer of pulverulent kelp 15 is placed over this wad 13. Only sufficient kelp 15 is deposited to cover the wad completely. This layer may be 6 of an inch thick or less.
  • a second wad 16 of filtration 3 94,096 Paitented Dec. 27, 1 966 material similarly dimensioned is positioned within the cigarette 11 in spaced relation to the first wad 13. This distance between the wads 13, 16 should only be sufiicient to retain the kelp 15 spread across the wad 13.
  • Additional layers 17, 17 of kelp, supported by additional wads 18, 18 are optional, but improve the efficiency of the filter in removing the tars.
