Definitions

  • the present invention relates to tobacco smoke filters (e.g. for cigarettes) and their production.
  • cellulose acetate is the dominant material used in tobacco smoke filters. It is also known to use paper as a filtration material in filters, e.g. for cigarettes; paper offers a number of advantages over cellulose acetate in terms of enhanced biodegradability, higher filtration efficiencies at a given pressure drop and lower material cost. Despite these advantages, the use of paper filters is small and generally limited to niche applications. The main reason why paper filters have failed to attract widespread market interest is that they have a deleterious effect on the taste of the cigarette. This so-called 'paper taste' is often considered to impart a harsher, drier sensation to cigarette smoke.
  • US 5166366 discloses a gamma-octalactone a flavouring additive in a tobacco product.
  • the additive can be used in the tobacco itself or in the filter or paper wrapper of the smoking article.
  • KR 20090041668 discloses favouring paper filters with natural botanical extracts according to Database WPI Thomson Scientific London 2209-J08652.
  • EP 0342538 teaches the use of a paper sheet as flavourant sheet material which constitutes as an filter element in a heat tobacco article.
  • the flavouring agents are various ketones and alicyclic or aromatic lactones.
  • a further limitation with paper filters is their reduced retention of toxic phenolic compounds - for example phenol, cresols, catechol and resorcinol - found in volatile and semi-volatile phases of cigarette smoke, compared to cellulose acetate filters; this results in higher relative yields of phenolic compounds from cigarettes with paper filters. This is caused by the well-known selectivity of cellulose acetate filters towards phenolic compounds rather than any inherent deficiency with paper filters. However, it of course still desirable to enhance phenol retention of paper filters so a smoker would not be exposed to higher levels of phenolic compounds when smoking a paper filtered cigarette compared to a cellulose acetate filtered cigarette.
  • a filter for a cigarette which has the advantages of a paper filter (biodegradability etc.) without the deleterious paper taste effect and/or with phenolic retention at least similar to that of a cellulose acetate filter.
  • a tobacco smoke filter or filter element comprising: a tobacco smoke filtering material including paper; and a flavour enhancing additive (e.g. selected from ⁇ -Valerolactone, ⁇ -Hexalactone, ⁇ -Hexalactone, ⁇ -Heptalactone, ⁇ -Octalactone, ⁇ -Octalactone, 4-Hydroxy-3-pentenoic acid lactone, 5-Hydroxy-2-decenoic acid ⁇ -lactone, 4,4-Dibutyl- ⁇ -butyrolactone, Mintlactone, Dehydromenthofurolactone, 3-Butylidenephthalide, 3-n-Butylphthalide, Whiskey lactone or sedanenolide.
  • the filter or filter element may include one or more flavour enhancing additives.
  • flavour enhancing additive means an additive which reduces the deleterious "paper taste” effect on the taste of the cigarette and/or reduces smoker perception of a harsher, drier sensation in paper filtered cigarette smoke compared to a known cellulose acetate filtered cigarette. That is, the taste of a paper filtered cigarette containing the flavour enhancing additive should be within the normal cigarette-to-cigarette taste variability associated with commercial brands of cellulose acetate filtered cigarettes.
  • Various attempts have been made to categorise flavouring substances according to their chemical characteristics such that they are distributed in groups of structurally related compounds.
  • the flavour enhancing additive are selected from ⁇ -Valerolactone (assigned FEMA GRAS Number FEMA 3103), x-Hexalactone (FEMA 2556), ⁇ -Hexalactone (FEMA 3167), ⁇ -Heptalactone (FEMA 2539), ⁇ -Octalactone (FEMA 2796), ⁇ -Octalactone (FEMA 3214), 4-Hydroxy-3-pentenoic acid lactone (FEMA 3293), 5-Hydroxy-2-decenoic acid ⁇ -lactone (FEMA 3744), 4,4-Dibutyl-x-butyrolactone (FEMA 2372), Mintlactone (FEMA 3764), Dehydromenthofurolactone (FEMA 3755), 3-Butylidenephthalide (FEMA 3333), 3-n-Butylphthalide (FEMA 3334) and Whiskey lactone (FEMA 3803).
  • ⁇ -Valerolactone assigned FEMA GRAS Number FEMA 3

  • the tobacco smoke filter or filter element according to the invention may be of circumference 14 to 28 mm, for example 16 to 26 mm, for example 16 to 17 mm or 24 to 25 mm.

  • a tobacco smoke filter element of the invention may be of length 5 to 30mm, e.g. 6 to 20mm, e.g. 8 to 15 mm, e.g. 10 to 12 mm.

  • the tobacco smoke filter (or filter element) comprising a tobacco smoke filtering material including paper is of the same or similar structure to that of the filter sold under the trade mark PURACEL (of Filtrona International Limited), and further includes the flavour enhancing additive.
  • the tobacco smoke filter (or filter element) comprising a tobacco smoke filtering material including paper is of the same or similar structure to that of the filter sold under the trade mark CREST (of Filtrona International Limited), and further includes the flavour enhancing additive.
  • the flavour enhancing additive may be located on or in the filter or filter element (e.g. located on or impregnated in the paper and/or the wrapper if present, and/or the second or further filtering material, if present). If more than one flavour enhancing additive is present, the additives may be present in the same location (e.g. both/all in the paper) or in different locations (one flavour enhancing additive on the paper, one on the further filtering material etc).
  • flavour enhancing additive or additives as defined above for example as essential oil of seed of celery (celery seed oil)
  • a filter or filter element or in a cigarette with a paper filter, as described below] may overcome the 'paper taste' sensation and provide a cigarette with sensory characteristics similar to those from cellulose acetate filtered cigarettes.
  • the filter or filter element may further comprise a further additive which selectively reduces one or more phenolic compounds found in the volatile and/or semi-volatile phases of cigarette smoke.
  • the term "further additive which selectively reduces one or more phenolic compounds found in the volatile and/or semi-volatile phases of cigarette smoke” means an additive which proportionally reduces the yield of one or more phenolic compounds (for example, proportionally reduces one or more of phenol, cresol, catechol or resorcinol) in cigarette smoke to a greater extent than the majority of compounds in smoke (e.g. tar).
  • the filter or filter element may include more than one further additive which selectively reduces one or more phenolic compounds found in the volatile and/or semi-volatile phases of cigarette smoke.

  • their use in conjunction with a filter or filter element which contains paper, and a flavour enhancing additive or additives as discussed herein, may provide a filter cigarette which has a yield of phenolic compounds which is comparable to that from a conventional cellulose acetate filtered cigarette (i.e. more selective filtration than a conventional paper filter cigarette), and the desirable reduction in paper taste.
  • a filter element according to the invention may be used as a segment of a dual, triple, or other multi component (multiple segment), filter. Dual and other multiple component filters are known in the art.
  • a dual, triple, or other multi component, filter includes a granular additive(s) such as activated carbon, silica gels, zeolites, ion exchange resins or sepiolite. It is preferred that the granular additive is not included in the filter element of the invention (i.e. is included in one of the other segments of the multi component filter).
