  • Patent number: 9119418
    Abstract: A smoking article (1) in which a patch of web material (7) such as paper containing an adsorbent material therein, such as activated carbon, is positioned towards the mouth end of the smoking article (1) to achieve a flatter puff profile compared to a conventional cigarette by decreasing the smoke constituents in the final few puffs. Characteristics of the smoking articles may be changed to increase the delivery of smoke constituents in the first few puffs in order to maintain a constant ISO NFDPM yield. The adsorbent-containing paper extends over only a portion of the smoking article towards the mouth end and does not comprise a flavorant therein.
    Type: Grant

  • Patent number: 6311696
    Abstract: The invention relates to low delivery cigarettes, usually having a mainstream particulate matter delivery of about 9 mg or less. An embodiment has a rod of tobacco material and a filter element. The filter element is an alkali filter material section having a loading level of less than 12% by weight of the section. The characteristics of the cigarettes are arranged so that, when smoked, the alkaline filter material is exposed to an amount of smoke acceptable to achieve an increased perception of smoke impact.
