Definitions

  • the present invention relates to a smoking article that can be adjusted to provide different levels of taste intensity.
  • Filter cigarettes typically comprise a rod of tobacco cut filler surrounded by a paper wrapper and a cylindrical filter aligned in end-to-end relationship with the wrapped tobacco rod, with the filter attached to the tobacco rod by tipping paper.
  • the filter may consist of a plug of cellulose acetate tow wrapped in porous plug wrap.
  • Filter cigarettes with multi-component filters that comprise two or more segments of filtration material for the removal of particulate and gaseous components of the mainstream smoke are also known.
  • smoking articles which may be adapted by the consumer in order to vary the flavour intensity of the mainstream smoke delivered during smoking.
  • a smoking article in which the ventilation of the smoking article can be varied in order to vary the dilution of the mainstream smoke.
  • the filter of the smoking article may be manipulated by the consumer in order to vary the filtering properties of the smoking article and the resultant taste intensity.
  • CH 467 031 A1 also describes a filter having multiple segments which can be selectively removed by a consumer before or during smoking.
  • a smoking article comprising: a tobacco rod circumscribed by an outer wrapper having a plurality of perforations extending through the wrapper; and a filter comprising two or more filter segments in axial alignment with each other, wherein adjacent filter segments of the filter abut at an interface.
  • the two or more filter segments are at least partially circumscribed by a substantially air impermeable plug wrap.
  • a filter wrapper circumscribes a portion of the filter and an adjacent portion of the tobacco rod to connect the filter and the tobacco rod.
  • the filter wrapper includes one or more circumferential lines of weakness extending around the filter at a position corresponding to the position of an interface.
  • the substantially air impermeable plug wrap extends around the interface under the one or more circumferential lines of weakness such that the smoking article provides two or more different tar levels between 0.1 mg and 15 mg, wherein the tar level is determined when the smoking article is smoked under ISO conditions, and such that the levels of carbon monoxide delivery for each tar level are within 1 mg of each other, wherein the level of carbon monoxide delivery is determined when the smoking article is smoked under ISO conditions.
  • Smoking articles according to the invention provide an effective way for the consumer to vary the taste intensity of the smoking article between two or more discrete levels.
  • the provision of circumferential lines of weakness at the location of each interface between adjacent filter segments enables the filter segments to be separated from each other by breaking the filter wrapper along the lines of weakness.
  • the length of the filter may be varied in order to alter the taste intensity of the mainstream smoke delivered during smoking.
  • the overall length of the filter is reduced and less of the particulate phase of the smoke is removed by the filter. The resultant taste intensity increases as a result of the increased particulate phase delivery in the mainstream smoke.
  • the consumer can therefore choose to increase the taste intensity of the mainstream smoke delivered by a smoking article according to the invention by breaking off one or more filter segments from the mouth end of the filter. This provides the consumer with greater control and variety in the smoking experience that can be delivered from a single cigarette design.
  • the number of discrete taste levels available to the consumer can be changed by adapting the number of filter segments in the filter.
  • the number of available taste levels corresponds to the number of filter segments so that additional, discrete taste levels can be incorporated through the addition of filter segments.
  • smoking articles according to the invention having two filter segments can provide two different taste levels and smoking articles according to the invention having three filter segments can provide three different taste levels.
  • the filter of smoking articles according to the invention comprises three filter segments in axial alignment with each other, thereby providing two interfaces.
  • interface is used in the present specification to define the area or plane where adjacent filter segments abut one another, such that the ends of the filter segments come into contact with each other.
  • adjacent filter segments may not be in contact with each other but may be separated by a narrow space or cavity.
  • the one or more lines of weakness in the filter wrapper extend around the filter at a position corresponding to the space between the adjacent filter segments.
  • the construction of the filter of smoking articles according to the invention allows consumers to choose between two or more discrete taste levels and to achieve the desired taste level with a simple manipulation of the filter to remove one or more filter segments from the mouth end of the filter.
  • the arrangement of the present invention facilitates the variation in the taste of the mainstream smoke compared with the more complicated arrangements of the prior art.
  • the taste levels are well defined such that consistent taste levels can be provided to the consumer with all smoking articles having the same arrangement of filter segments.
  • Smoking articles according to the invention provide two or more different tar levels between about 0.1 mg and about 15 mg, between about 0.1 mg and about 10 mg, between about 1 mg and about 15 mg, more preferably between about 4 mg and about 12 mg, wherein the tar level is determined when the smoking article is smoked under ISO conditions (35ml puffs lasting 2 seconds each, every 60 seconds).
  • the term 'tar level' or 'particulate phase delivery' is used to refer to the total nicotine free dry particulate matter (NFDPM) of a smoking article under ISO conditions.
  • the smoking article provides three available tar levels of about 8 mg, about 10 mg and about 12 mg, wherein the higher levels of about 10 mg and about 12 mg are achieved by breaking off one and two segments, respectively.
  • Other tar levels that may be provided by the cigarette are about 1 mg, about 2 mg, about 4 mg, and about 6 mg.
  • the intervals between the tar delivery levels may be the same.
  • the intervals between the tar levels may be about 1 mg, about 2mg, about 3 mg, or about 4 mg. In other cases, the intervals between the three or more available tar levels may be different.
  • the plug wrap circumscribing the two or more filter segments of smoking articles according to the invention is substantially air impermeable.
  • the substantially air impermeable plug wrap may circumscribe the filter along all or a part of its length but is arranged so that the interfaces between adjacent filter segments are covered by the plug wrap.
  • substantially air impermeable is used in relation to the present invention to describe a sheet material that, when incorporated into the filter, allows less than 10% dilution of the mainstream smoke through the ingress of ambient air into the filter.
  • the substantially air impermeable plug wrap may be non porous and does not include any perforations.
  • the substantially air impermeable plug wrap has an air permeability of less than 200 Coresta units, preferably less than 100 Coresta units, and more preferably less than 20 Coresta units. In some such cases, the substantially air impermeable plug wrap can have a lower limit of 1 Coresta unit.
  • the 'Coresta' unit is the unit of air permeability of a sheet material, which corresponds to the flow of air (cubic centimetres per minute) passing through a 1 square centimetre surface area of the test material at a measuring pressure of 1.00 kPa.
  • the measuring pressure is the difference in pressure between the two faces of the test material during measurement.
  • the units corresponding to the Coresta unit are cubic centimetres per minute per square centimetre (cm 3 min -1 cm -2 ) at 1.00 kPa.
  • a suitable method for determining the air permeability of sheet materials for use in the present invention is described in ISO Standard 2965:2009.
  • a substantially air impermeable plug wrap over the interfaces between the adjacent filter segments ensures that the one or more lines of weakness in the filter wrapper have a minimal effect on the ventilation of the filter. Instead, the required ventilation is provided by the plurality of perforations in the outer wrapper of the tobacco rod.
  • the positioning of the ventilation on the tobacco rod rather than the filter advantageously ensures that the overall level of dilution of the mainstream smoke can be controlled and maintained at a predetermined level, including when one or more filter segments are removed in order to vary the taste level.
  • the ventilation on the tobacco rod is substantially unaffected by the removal of filter segments so that a consistent level of ventilation can be provided for each taste level.
  • the level of ventilation would be significantly affected by the removal of the filter segments and it would generally not be possible to provide a controlled level of ventilation for all of the taste levels.
  • the positioning of the ventilation on the tobacco rod ensures that the carbon monoxide (CO) delivery of smoking articles according to the invention is relatively consistent at each of the different taste levels.
  • the carbon monoxide delivery is therefore substantially unaffected by the removal of one or more filter segments in order to adjust the tar level.
  • the levels of carbon monoxide delivery for each taste level are within about 1 mg of each other, more preferably within about 0.3 mg and more preferably within about 0.1 mg.
  • the level of carbon monoxide delivery is determined when the smoking article is smoked under ISO conditions.
  • the filter wrapper is broken along the one or more lines of weakness at the interface and the underlying substantially air impermeable plug wrap must also be torn or separated along the interface.
  • the substantially air impermeable plug wrap is formed of a sheet material having a low basis weight.
  • the substantially air impermeable plug wrap is formed of a plastic, such as a polylactic acid (PLA) film.
  • the plastic plug wrap may have a basis weight of less than about 70 grams per square metre (gsm), more preferably less than about 40 gsm.
  • the substantially air impermeable plug wrap may alternatively be formed of a paper material having a basis weight of less than about 25 gsm, more preferably less than about 20 gsm.
  • the filter wrapper connecting the filter to the tobacco rod is preferably a tipping wrapper, such as a tipping paper of the type used in conventional smoking articles.
  • the filter wrapper is provided with one or more lines of weakness at the position or positions corresponding to each interface between adjacent filter segments.
  • the one or more lines of weakness when the one or more lines of weakness 'correspond' to a position of one of the interfaces it is meant that the line of weakness is within about 2 mm of the interface. Preferably, the one or more lines of weakness are within about 1 mm of the interface, or more preferably within about 0.5 mm.
  • the one or more lines of weakness are preferably provided at a position corresponding to the space between adjacent filter segments.
  • the one or more lines of weakness are therefore provided within about 2 mm of the space, more preferably within about 1 mm of the space, or more preferably within about 0.5 mm.
  • the one or more lines of weakness in the filter wrapper are formed by one or more circumferential rows of perforations.
  • each line of weakness may be formed by a row of micro laser perforations.
  • each row of perforations comprises between 10 and 20 holes per centimetre, more preferably about 15 holes per centimetre.
  • the filter wrapper for use in smoking articles according to the invention will be pre-perforated prior to being wrapped around the smoking articles.
  • the position of the rows of perforation on the filter wrapper can be controlled so that the position corresponds to the position of the interfaces in the filter. Suitable apparatus and methods for perforating the filter wrapper will be known to the skilled person.
  • the outer wrapper circumscribing the tobacco rod is preferably a paper cigarette wrapper, of the type used in conventional smoking articles.
  • the outer wrapper is provided with a plurality of perforations.
  • the perforations may be provided in one or more rows extending circumferentially around the tobacco rod. Alternatively, the perforations may be uniformly or non-uniformly distributed over an area of the outer wrapper.
  • the outer wrapper for use in smoking articles according to the invention will be pre-perforated prior to being wrapped around the tobacco rod.
  • the outer wrapper comprises a plurality of electrostatic perforations.
  • the outer wrapper has an air permeability that allows at least 20% air dilution through the cigarette rod, more preferably at least 50% and most preferably at least 75%.
  • the outer wrapper may be perforated to provide an air permeability of at least 200 Coresta units, more preferably at least 350 Coresta units.
  • An upper limit for the Coresta units of the outer wrapper may be determined by the required strength and other attributes of the wrapper.
  • the air permeability may be less than 2000 Coresta units, preferably less than 700 Coresta units, or more preferably less than 500 Coresta units.
  • the total ventilation in the smoking article preferably provides air dilution of the mainstream smoke of at least about 20%, more preferably at least about 50% and more preferably at least about 75%.
  • the filter preferably provides less than 10% dilution as a result of the substantially impermeable plug wrap. The majority of the air dilution is therefore provided by the ventilation in the outer wrapper of the tobacco rod.
  • the two or more filter segments of smoking articles according to the invention may take a variety of forms and suitable filter segments will be known to the skilled person.
  • the two or more filter segments may be of the same construction and materials as each other or may have a different construction, or contain different filtration material or additives.
  • the two or more filter segments are each formed of a plug of fibrous filtration material, such as cellulose acetate tow or paper.
  • Each segment may also comprise a plurality of sections, or sub-segments.
  • one or more of the filter segments may comprise two or more sections or sub-segments disposed between the lines of weakness in the filter wrapper.
  • the filter segments may have the same or different filament denier, total denier, or both.
  • the filament denier of the fibrous filtration material of the filter segments may be between about 1.5 and 8.
  • the total denier of the fibrous filtration material of the filter segments may be between about 15,000 and 50,000.
  • the filter segments at the mouth end of the filter have a lower filament denier, or smaller diameter fibres, than the filter segments closer to the tobacco rod.
  • the total denier of the filter segments at the mouth end of the filter is higher than the filter segments closer to the tobacco rod. In this case, the mouth end filter segment has a higher linear density that the upstream segment or segments.
  • the resistance to draw (RTD) of the smoking articles of the present invention will vary depending on the number and length of the filter segments and the taste level selected by the consumer.
  • the RTD of the smoking article with all of the filter segments intact is between about 90 and 130 mm H 2 O.
  • Each of the two or more filter segments contributes to the overall RTD of the smoking article and the filter segments may have the same or different RTD values.
  • each filter segment has an RTD value between about 10 mm H 2 O and 50 mm H 2 O.
  • the RTD of the two or more filter segments increases towards the mouth end of the filter, such that the mouth end filter segment has a higher RTD that the upstream filter segment or segments.
  • the resistance to draw of a smoking article, filter or filter segment refers to the static pressure difference between the two ends of the specimen when it is traversed by an air flow under steady conditions in which the volumetric flow is 17.5 millilitres per second at the output end.
  • the RTD of a specimen can be measured using the method set out in ISO Standard 6565:2002.
