Definitions

  • the present invention relates to a filter for a smoking article having a substantially transparent wrapper, and a method of manufacturing such filters.
  • the present invention also relates to smoking articles incorporating such filters.
  • Filter cigarettes typically comprise a cylindrical rod of tobacco cut filler surrounded by a paper wrapper and a cylindrical filter axially aligned in an abutting end-to-end relationship with the wrapped tobacco rod.
  • the cylindrical filter typically comprises a filtration material circumscribed by a paper plug wrap.
  • the wrapped tobacco rod and the filter are joined by a band of tipping wrapper, normally formed of an opaque paper material that circumscribes the entire length of the filter and an adjacent portion of the wrapped tobacco rod.
  • a number of smoking articles in which an aerosol generating substrate, such as tobacco, is heated rather than combusted have also been proposed in the art.
  • the aerosol is generated by heating the aerosol generating substrate.
  • Known heated smoking articles include, for example, smoking articles in which an aerosol is generated by electrical heating or by the transfer of heat from a combustible fuel element or heat source to an aerosol generating substrate.
  • volatile compounds are released from the aerosol generating substrate by heat transfer from the heat source and entrained in air drawn through the smoking article. As the released compounds cool they condense to form an aerosol that is inhaled by the consumer.
  • smoking articles in which a nicotine-containing aerosol is generated from a tobacco material, tobacco extract, or other nicotine source, without combustion, and in some cases without heating, for example through a chemical reaction.
  • the wrappers of the smoking articles are typically provided such that opposed edges of each wrapper overlap with one another along a longitudinal overlapping region to form a seam.
  • An adhesive such as Polyvinyl alcohol (PVA) or a hot melt adhesive, is used to secure the opposed edges of each wrapper to one another along the seam.
  • PVA Polyvinyl alcohol
  • hot melt adhesive is used to secure the opposed edges of each wrapper to one another along the seam.
  • smoking articles having a wrapper which is at least partially transparent such that a consumer can observe at least a portion of the smoking article through the wrapper.
  • smoking articles have been provided with tipping wrappers formed from a transparent polymeric material.
  • a transparent polymeric tipping wrapper provides a different surface feel compared to traditional paper tipping wrappers, which tends to be disliked by consumers.
  • the seam of the substantially transparent plug wrap is formed using an adhesive, such as PVA or a hot melt adhesive
  • the seam will not be transparent and consequently is visibly discernibly from the remainder of the plug wrap. This is particularly problematic where the substantially transparent plug wrap underlies a tipping paper with a cut-out window, since registration will be required to avoid the seam being placed under the window.
  • a mouthpiece for a smoking article comprising: at least one mouthpiece element; a substantially transparent wrapper wrapped around the at least one mouthpiece element such that first and second opposed edges of the substantially transparent wrapper overlap with each other along a longitudinal overlapping region; and an agent disposed between the first and second opposed edges of substantially transparent in at least a portion of the longitudinal overlapping region; wherein the substantially transparent wrapper comprises an acetate ester of cellulose, and wherein the agent comprises an ester of glycerol.
  • the ester of glycerol of the substantially transparent wrapper is triacetin (also known as glycerol triacetate).
  • the ester of glycerol may be triethyl citrate, as an alternative or in addition to triacetin.
  • a substantially transparent seam can be obtained by using an agent, or bonding agent, comprising an ester of glycerol and a substantially transparent wrapper comprising an acetate ester of cellulose.
  • the ester of glycerol is a substantially transparent agent, and unlike conventional adhesives, interacts with the acetate ester of cellulose in the wrapper, to bond or otherwise weld the overlapping portions in the longitudinal overlapping region directly to one another. This can result in one of the overlapping edges seamlessly transitioning into the other overlapping edge in the overlapping region, rather than there being a distinct joint between the two overlapping edges, as would be the case with a conventional adhesive.
  • a mouthpiece for a smoking article comprising: at least one mouthpiece element; and substantially transparent sheath circumscribing the at least one mouthpiece element, wherein the substantially transparent sheath comprises an acetate ester of cellulose, and wherein the substantially transparent sheath comprises a longitudinally extending portion formed from the interaction of the acetate ester of cellulose with an ester of glycerol.
  • a mouthpiece for a smoking article comprising: at least one mouthpiece element; and substantially transparent sheath circumscribing the at least one mouthpiece element, wherein the substantially transparent sheath comprises an acetate ester of cellulose, and wherein the substantially transparent sheath comprises a longitudinally extending portion having a thickness of about two times the thickness of the remainder of the substantially transparent sheath, as measured in a radial direction of the mouthpiece.
  • substantially transparent is used herein to describe a material which allows at least a sufficient proportion of incident light to pass through it so that it is possible to see through the material.
  • the substantially transparent wrapper allows sufficient light to pass through it such that an underlying mouthpiece segment is visible through the wrapper.
  • the transparency of the substantially transparent wrapper may be evaluated in accordance with ASTM D1003 - 13.
  • the substantially transparent wrapper may be completely transparent.
  • the substantially transparent wrapper may have a lower level of transparency whilst still transmitting sufficient light so that the underlying mouthpiece segment is visible through the substantially transparent wrapper.
  • the substantially transparent wrapper may be tinted or coloured.
  • the acetate ester of cellulose is selected from the group of cellulose acetate, cellulose diacetate and cellulose triacetate. Particularly preferably, the acetate ester of cellulose is cellulose diacetate.
  • the substantially transparent wrapper may be composed of additional compounds in addition to the acetate ester of cellulose.
  • the substantially transparent wrapper consists essentially of an acetate ester of cellulose. This can help to ensure that sufficient acetate ester of cellulose is present at the surface of the substantially transparent wrapper and therefore able to react with the ester of glycerol.
  • the substantially transparent wrapper may comprise one or more layers, with at least one layer comprising an acetate ester of cellulose.
  • the substantially transparent wrapper comprises a polymeric layer, such as a layer of polyvinyl alcohol, disposed between two layers comprising an acetate ester of cellulose, such as cellulose diacetate.
  • the agent is provided in the form of a line extending along the overlapping region.
  • the line has a width of from about 0.1 millimetres to about 5 millimetres, more preferably of from about 0.5 millimetres to about 3 millimetres, even more preferably of from about 1 millimetres to about 2.5 millimetres.
  • the agent is provided in an amount of from about 0.5 milligrams to about 1.5 milligrams.
  • the mouthpiece of smoking articles in accordance with the present invention may comprise a filter including one or more segments of filtration material.
  • the mouthpiece may comprise a single segment of filtration material, or the mouthpiece may comprise a multi-segment filter including two or more segments of filtration material.
  • the filter segments may be of the same construction and materials as each other. Preferably, however, the filter segments have a different construction, and/or contain different filtration material to each other.
  • the mouthpiece comprises two or more segments of filtration material
  • at least two segments of filtration material may be spaced apart to form a cavity therebetween.
  • the cavity may be at least partially filled with a flavourant material.
  • At least one of the filter segments may include a flavourant material. This may be in addition to any flavourant material provided in a cavity when present.
  • the flavourant material is particulate flavourant material.
  • suitable particulate flavourant materials include particles of a sorbent or cellulosic material impregnated with a liquid flavourant.
  • the particulate flavourant material may comprise particles of plant leaf, as described in EP-A-1 ,958,523.
  • flavourant material may include leaf from tobacco, green tea, peppermint, spearmint, laurel, eucalyptus, basil, sage, verbena and tarragon.
  • portions of mint plants may also be used.
  • the term 'mint' refers to plants that belong to the genus Mentha.
  • the plant material may alternatively be in the form of a seed, root, bark and/or flower, such as those typically used as spices.
  • the flavourant material is provided in a capsule which is adapted to release at least a portion of a fluid when the capsule is subjected to external force, such as squeezing, by the consumer.
  • the mouthpiece may also include a particulate material that does not comprise a flavourant, such as beads or granules of a cellulosic material or an adsorbent. This may be in addition to or as an alternative to the particulate flavourant materials described above.
  • adsorbents include activated carbon, carbon beads, active aluminium, zeolites, sepiolites, molecular sieves and silica gel.
  • the filtration material is preferably a plug of fibrous filtration material, such as cellulose acetate tow or paper.
  • a filter plasticiser may be applied to the fibrous filtration material in a conventional manner, by spraying it onto the separated fibres, preferably before applying any particulate material to the filtration material.
  • the mouthpiece may include a variety of different types of filter segments or combinations of filter segments, including those described above as well as other types of filter segments that would be known to the skilled person, such as segments including restrictors and segments that are used for adjusting the resistance to draw (RTD).
  • the substantially transparent wrapper may be a plug wrap surrounding the filter material.
  • any or all of the segments may each be individually wrapped in a segment plug wrap.
  • the segments of the filter may then be subsequently attached to one another in a conventional manner using a substantially transparent wrapper, which forms a combining plug wrap.
  • at least one of the segment plug wraps is preferably transparent in addition to the combining plug wrap being transparent, and in some cases these transparent wrappers are formed from the same material.
  • the present invention advantageously enables the overlapping region to have a transparency that is close to or the same as that of the remainder of the substantially transparent wrapper. Accordingly, preferably, the transparency level of overlapping region of the substantially transparent wrapper is within 10 percent, more preferably 5 percent of the transparency level of the remainder of the substantially transparent wrapper.
  • the transparency level may be evaluated in accordance with ASTM D1003 - 13.
  • the thickness of the substantially transparent wrapper is preferably about 10 micrometers or more.
  • the thickness of the substantially transparent wrapper is preferably about 200 micrometers or less, more preferably about 100 micrometers or less. More preferably, the thickness of the substantially transparent wrapper is between about 25 micrometers and about 75 micrometers.
  • the basis weight of the substantially transparent wrapper is preferably at least about 15 grams per square meter (gsm). More preferably, the basis weight of the substantially transparent wrapper is between about 20 gsm and about 130 gsm.
  • the mouthpiece further comprises a paper wrapper circumscribing at least a portion of the substantially transparent wrapper.
  • a window may be provided in the paper wrapper such that an underlying mouthpiece segment can be viewed through the window and the substantially transparent wrapper. This allows a consumer to view a portion of the mouthpiece underlying the substantially transparent wrapper.
  • the paper wrapper may include a single window or multiple windows as desired. Where the paper wrapper includes multiple windows, they may be identical windows or they may have different sizes or shapes to accommodate different mouthpiece designs.
  • the window may be provided by forming a cut-out in the paper wrapper.
  • the paper wrapper may be formed from a composite material having a band of transparent material which circumscribes at least a portion of the mouthpiece to form a window.
  • the paper wrapper can comprise two bands of paper material which are spaced apart along the length of the mouthpiece to define a gap, the gap forming the window.
  • the window may extend around the entire circumference of the mouthpiece. However, preferably, the window extends around only a portion of the circumference of the mouthpiece.
  • the mouthpiece preferably includes a high basis weight transparent plug wrap underlying the paper wrapper and extending across the window to prevent the mouthpiece from collapsing or breaking at the window during use.
  • the basis weight of the substantially transparent plug wrap can be at least 60 gsm, preferably around 80 gsm.
  • the window preferably overlies at least a portion of the cavity so that a consumer can observe the cavity through the window and the substantially transparent layer.
  • the paper wrapper may include a window which overlies at least a portion of a filter segment which includes a particulate material so that a consumer can observe the particulate material through the window and the substantially transparent layer.
  • the paper wrapper also includes a window overlying a cavity within the mouthpiece, these may be the same window extending over both portions of the mouthpiece or they may be different windows.
