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.
- the Korean patent application KR 2009 0041668 discloses a cigarette filter made of paper and flavoured with natural botanical extracts It would thus be highly desirable to overcome this 'paper taste' and create a smoking sensation from paper-filtered cigarettes that is comparable to that of conventional cellulose acetate filtered cigarettes. In addition, discarded paper butts would degrade much quicker than those of cellulose acetate, resulting in significant environmental improvements. However, any measure to overcome the paper taste must also result in a smoking experience which is comparable to that from a conventional cellulose acetate filtered cigarette. This has not been achieved by previous attempts to overcome 'paper taste' deficiencies (e.g. by adding specific flavouring such as menthol).
- 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 made of paper and essential oil of seed of celery.
- the essential oil of seed of celery is present in the filter or filter element in an amount which is up to 1 % by weight (w/w) of the paper in the filter or filter element.
- 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 of the invention may be of length 10 to 40 mm, e.g. 15 to 35 mm, e.g. 20 to 30 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 paper may be any paper (in any form) which is conventionally used in filters or filter elements.
- the paper may be, for example, filtering paper, aperture paper, crepe paper etc..
- the paper may be in the form of a web of paper, e.g. gathered laterally into, and held, in rod form.
- the fibre of the paper web may be 100% natural fibre (e.g. wood pulp), 100% synthetic fibre, or mixtures of the two (for aperture paper, the paper is preferably 100% natural fibre).
- bonding agents e.g. plasticisers
- the paper may be in the form of a longitudinally corrugated and/or fibrillated web of paper, for example gathered laterally into, and held, in rod form, for example as disclosed in GB2075328 .
- the filter or filter element may be (or include) a rod (e.g. cylindrical rod) of filtering material, including (e.g. formed from) the paper (e.g. the web of paper).
- the filter or filter element may include a tobacco smoke filtering material which is made of paper and one or more further filtering materials.
- the filter or filter element may include a tobacco smoke filtering material in the form of a coherent web made of paper and a second filter material and, optionally, one or more further filter materials.
- the filter or filter element may be (or include) a rod including (e.g.
- the second and any further filter materials may be, for example, cellulose acetate tow, a (further) paper (e.g. different to the other paper in the filter or filter element), a non-woven web made from natural and/or synthetic fibres, other fibre tow, for example polypropylene etc..
- the tobacco smoke filter or filter element) comprising a tobacco smoke filtering material made of paper is of the same or similar structure to that of the filter sold under the trade mark MYRIA (of Filtrona International Limited), and further includes the essential oil of seed of celery.
- the tobacco smoke filter or filter element comprising a tobacco smoke filtering material made of 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 essential oil of seed of celery.
- the tobacco smoke filter or filter element comprising a tobacco smoke filtering material made of 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 essential oil of seed of celery.
- the filter or filter element may be overwrapped with a wrapper, for example a wrapper of an air-permeable paper.
- Filters or filter elements according to the invention can be wrapped in the standard range of plugwraps and can be ventilated in any conventional manner.
- the essential oil of seed of celery may be located on or in the filter or filter element comprising a tobacco smoke filtering material made of paper (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 a second or further flavour enhancing additive is present, the second or further flavour enhancing additive may be present in the same location (e.g. both/all in the paper) or in a different location to the essential oil of seed of celery .
- 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.
- the further additive which selectively reduces one or more phenolic compounds found in the volatile and/or semi-volatile phases of cigarette smoke is a polyethylene glycol (e.g. PEG200, PEG300, PEG400) or a methoxypolyethylene glycol (e.g. mPEG350).
- the further additive which selectively reduces one or more phenolic compounds found in the volatile and/or semi-volatile phases of cigarette smoke is present in the filter or filter element in an amount which is up to 20% by weight (w/w) of the paper in the filter or filter element.
- the further additive which selectively reduces one or more phenolic compounds may be present in an amount which is from 1 to 19% by weight (e.g.
- the total amount of further additives is up to 20% by weight (w/w) of the paper in the filter or filter element.
- the further additive which selectively reduces one or more phenolic compounds may be located on or in the filter or filter element (e.g. located on or impregnated in the paper and/or the wrapper, and/or the second or further filtering material, if present). If more than one further additive is present, the additives may be present in the same location (e.g. both/all in the paper) or in different locations (one additive on the paper, one on the further filtering material etc).
- polyethylene glycols e.g. PEG200, PEG300 and PEG400
- methoxy-polyethylene glycols e.g. mPEG 350
- 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). In an example the filter element of the invention forms the mouth end segment of a dual segment filter, while tobacco end segment of the dual filter includes a granular additive.

- the filter may, for example, be joined to the wrapped tobacco rod by ring tipping (which engages around just the adjacent ends of a [wrapped] filter and rod to leave much of the filter wrapper exposed) or by a full tipping overwrap (which engages around the full filter length and adjacent end of the tobacco rod).
- Any filter or filter cigarette according to the invention may be unventilated, or may be ventilated by methods well known in the art, e.g.
- the final filter cigarette may be of any circumference range traditionally used in smoking products (e.g. c. 14 to c. 28 mm circumference).
- the present invention also provides a filter cigarette which includes a tobacco smoke filter or filter element of the invention, as disclosed above.
- the filters or filter elements according to the invention may be made as continuous rods, as is well known in the art.
- the continuous rod as it issues continuously from the production machine outlet is cut into finite lengths for subsequent use. This cutting may be into individual filters or filter elements as defined and described above, each of which is then attached to an individual wrapped tobacco rod to form a filter cigarette.
- the continuously issuing rod is first cut into double or higher multiple (usually quadruple or sextuple) lengths for subsequent use; when the initial cut is into quadruple or higher lengths, then the latter are subsequently cut into double lengths for the filter cigarette assembly - in which the double length filter rod is assembled and joined (by ring tipping or full tipping overwrap) between a pair of wrapped tobacco rods with the combination then being severed centrally to give two individual filter cigarettes.
- the invention includes (e.g. double and higher) multiple length filter rods (and/ or filter element rods), including a plurality of filter rods (filter element rods), e.g. joined end to end.
- the filter or filter element may include a further flavouring agent (in addition to the essential oil of seed of celery), for example menthol.
- a filter cigarette comprising: a filter or filter element comprising a tobacco smoke filtering material made of paper; and a wrapped tobacco rod; wherein the filter cigarette further comprises essential oil of seed of celery.
- the filter cigarette may include one or more flavour enhancing additives.
- the essential oil of seed of celery may be located on or in the filter or filter element [e.g. located on or impregnated in the paper and/or the filter wrapper if present, and/or the second or further filtering material, if present], and/or located on or in the tobacco, and/or on or in the wrapper of the wrapped tobacco rod. If a second or further flavour enhancing additive is present, the second or further flavour enhancing additive may be present in the same location (e.g. both/all in the paper) or in different location to the essential oil of seed of celery .
- the filter cigarette 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, as defined above and disclosed herein.
- the further additive which selectively reduces one or more phenolic compounds may be located on or in the filter or filter element [e.g. located on or impregnated in the paper and/or the filter wrapper if present, and/or the second or further filtering material, if present], and/or located on or in the tobacco, and/or on or in the wrapper of the wrapped tobacco rod.
- essential oil of seed of celery may provide improved taste when used in (or with) smoking articles that heat, rather than burn, tobacco.
- smoking articles that heat rather than burn tobacco are known. Although such smoking articles generally feature a cellulose acetate filter, they tend to provide a poorer taste in comparison to conventional cigarettes with cellulose acetate filters. The applicants have surprisingly found that inclusion of essential oil of seed of celery in the filters used in smoking articles that heat rather than burn tobacco results in improved sensory characteristics for these smoking articles.
- a smoking article which heats tobacco excludes smoking articles such as cigarettes and cigars, the use of which involves burning of the tobacco.
- Sample paper filters were made from a cylindrical rod (of length 15 mm and circumference 24.50 mm) of paper formed from a non-aperture porous web of 100% wood pulp fibre according to the method set out in GB2075328A .
- the paper is formed on an inclined wire machine from fibres 2.5 to 6mm in length and has a finished substance (before corrugation) of 15 to 35 grammes per square metre (by the method set out in GB2075328A ).
- a further additive in the form of polyethylene glycol is applied to the paper, also by methods well known in the art.
- the longitudinally advancing finished web of paper (to which the additives have been applied) is then longitudinally advanced between cooperating rolls having circumferentially-extending corrugations, and thereafter continuously gathered (while longitudinally advancing as a paper web) laterally into rod form.
- the resulting continuously produced rod is continuously cut transversely into finite lengths to give the product filter or filter rod, by methods which are also known in the art.
- Sample cigarettes were assembled using the sample filters made as set out above.
- the yield of phenol, o-, m- and p-cresol (collectively termed the mono-hydroxyphenols) were then measured for all samples under ISO smoking conditions.
- the tar yields from the sample cigarettes were also measured in order that the ratios of phenols to tar could be assessed.
- the yields were compared with a control cigarette (of equal dimensions but containing a conventional cellulose acetate filter), also smoked under ISO smoking conditions.
- sample filters according to the invention which include a paper filter selectively reduce phenols; the exposure of the phenol compounds mentioned above was found to be comparable with a cellulose acetate filter cigarette.
- the filters were removed from a first group of the cigarettes and replaced with machine-made paper filters of equivalent tar retention. These filters are referred to as unmodified paper-filtered cigarettes ('P'), below.
- the filters were also removed from a second group of the cigarettes and replaced with machine-made paper filters of equivalent tar retention (as with the P group). A metered quantity of essential celery seed oil was injected into each paper filter and the cigarettes allowed to age for around 3-4 weeks. These filters are referred to as modified paper-filtered cigarettes ('P+'), below.
- the panel compared unmodified paper-filtered cigarettes ('P') with the monoacetate control ('C'); and the modified paper filters ('P+') versus 'C'.
