Definitions

  • the present invention relates to a wrapping paper for a smoking article and a smoking article comprising a wrapping paper.
  • US 5,379,788 teaches a cigarette system which has a greater number of puffs than a conventional cigarette of same dimensions and length of tobacco rod, namely at least about 14 puffs.
  • the cigarettes are intended to be partially smoked, extinguished, stored and then resmoked.
  • a filter is attached to the tobacco rod of the cigarette constructed to provide a per-puff delivery profile of tar, nicotine and flavor to the smoker which is approximately the same for both smokings of the cigarette.
  • the greater-than-normal number of puffs is achieved by employing a slower burning tobacco blend, greater tobacco density and/or burn rate retardant paper.
  • US 2011/083,687 A1 discloses a burn rate of a smoking article which is reduced by incorporating into the paper a filler having a median particle size larger than about 2.5 microns and thereby increasing the number of puffs.
  • Japanese Patent No. 2834325 discloses a cigarette in which a cut tobacco density is set at 300 mg/cc or more in order to decrease the combustion rate of the cut tobacco rod, thereby increasing the number of puffs provided by the cigarette.
  • US 2006/0021625 A1 relates to make-your-own cigarettes and packaged kits and components of make-your- own cigarette. It describes a wrapping paper for a smoking article, comprising a base paper, wherein the base paper comprises a fibrous material, a filler material, and burning additives.
  • the problem of the present invention is to provide a wrapping paper that can increase the puff count of a smoking article without changing the tobacco rod length or diameter and without impacting on the TNCO levels of the smoking article.
  • the inventors have found that by providing a wrapping paper with a certain porosity and certain amount of a burning additive it is possible to increase the puff count of the smoking article.
  • a first aspect of the present invention relates to a wrapping paper for a smoking article, comprising a base paper, wherein the base paper comprises a fibrous material, a filler material and one or more burning additives, wherein a paper porosity of the base paper is of 10 to 60 CU, a total amount of burning additive is of 0.1 to 0.7 wt.-% based on the dry weight of the base paper, and a basis weight of the base paper is 20 to 26 g/m 2 .
  • a smoking article comprising a charge of smokable material surrounded by a wrapping paper according to the first aspect of the invention is disclosed.
  • the cigarette 10 has a tobacco rod 11 consisting of a tobacco filler 13 that is wrapped with a wrapping paper 12 of the present invention in the form of a column.
  • An ordinary filter 15 may be attached to the proximal end (namely, the downstream end in the inhaling direction) 11b of the tobacco rod 11 by using a tipping paper 14 according to a conventional method.
  • a plurality of stripe-shaped burn-suppressing regions 122 which are coated as will be explained in the forthcoming description, are formed on one of the surfaces of the base paper 121 that constitutes the wrapping paper 12 of the present invention. These stripe-shaped burn-suppressing regions 122 are formed apart from each other in the circumferential direction of the tobacco rod 11.
  • Non-burn-suppressing regions 123 are formed between the adjacent stripe-shaped burn-suppressing regions 122. Since the regions 123 are constituted by a part of the base paper 121, they can burn in an ordinary smoking state. Therefore, the regions 123 each act as a non-burn-suppressing region.
  • the stripe-shaped burn-suppressing regions 122 each may have a width of 1 to 6 mm in the circumferential direction. The distance between the adjacent burn-suppressing regions 122 may be 2 to 20 mm.
  • a non-burn-suppressing region 124 may be provided to the region covering a distance d from the tip 11a of the base paper 121.
  • FIG. 3 is a schematic perspective view, partly broken away, showing an example of a cigarette that is wrapped with a cigarette paper having annular band-shaped burn-suppressing regions according to another embodiment of the present invention.
  • the cigarette 20 has a similar structure to that of the cigarette 10 shown in FIG. 2 , except for the structure of the burn-suppressing regions in the wrapping paper. Therefore, in FIG. 3 , an identical reference number is assigned to the same element as the constitutional element in FIG. 2 , and the explanation thereof is omitted.
  • annular band-shaped burn-suppressing regions 211 are formed on the base paper 121 of the wrapping paper 21 wrapping the tobacco filler 13, defining burn-suppressing regions. These annular band-shaped burn-suppressing regions 211 are formed apart from each other in the longitudinal direction of the tobacco rod 11.
  • Non-burn-suppressing regions 212 are formed between the adjacent annular band-shaped burn-suppressing regions 211. Since the non-burn-suppressing regions 212 are constituted by a part of the base paper 121, they can burn in an ordinary smoking state. Therefore, the regions 212 each act as non-burn-suppressing region, as the regions 123 in FIG. 2 do.
  • the annular band-shaped burn-suppressing regions 211 each may have a width of 4 to 7 mm in the longitudinal direction. The distance between the adjacent burn-suppressing regions 24 may be 18 to 25 mm.
  • Smoking articles as referred to herein are not particularly limited and can for example be cigarettes, cigarillos or the like. They typically have a generally cylindrical rod shaped configuration and include a charge, roll, or column of smokable material, such as shredded tobacco (e.g. in cut filler form), which is surrounded by a paper wrapper forming a so-called "tobacco rod".
  • a cigarette or cigarillo usually also has a cylindrical filter element aligned in end-to-end relationship with the tobacco rod.
  • the filter element may, for example, comprise a plug of cellulose acetate tow, and the tow is circumscribed by a wrapper material known as "plug wrap".
  • the filter element is attached to one end of the tobacco rod using a circumscribing wrapping material known as "tipping wrapper".
  • the filter element wrapped by the tipping wrapper is known as "mouthpiece element”.
  • wt.-% is to be understood as weight percent, based on the dry weight of the base paper of the wrapping paper, unless explicitly otherwise specified. In the present disclosure, all amounts given in wt.-% in a particular embodiment add up to 100 wt.-%. The weight percent are thereby calculated by dividing the mass of each component by the dry mass of the base paper.
  • TNCO levels as referred to herein stand for tar, nicotine and carbon monoxide levels and can be measured by any suitable method. In the present invention this is done according to ISO 3308:2012.
  • the symbol "CU” herein designates the CORESTA air permeability unit that is commonly used in paper specifications by smoking article designers.
  • the CORESTA air permeability unit is defined as: "the volumetric flow rate of air in cubic centimeters per minute (cm 3 /min) passing through a 1 square centimeter (cm 2 ) sample of substrate at an applied pressure difference of 1 kilo-Pascal (kPa).” and are measured according to ISO 6565:2011.
  • the number of puffs of a smoking article may be measured by any suitable method. In the present invention this is done according to ISO 3308:2012.
  • the present invention relates to a wrapping paper for a smoking article comprising a base paper, wherein the base paper comprises a fibrous material, a filler material and one or more burning additives, wherein a paper porosity of the base paper is of 10 to 60 CU, a total amount of burning additive is of 0.1 to 0.7 wt.-% based on the dry weight of the base paper and a basis weight of the base paper is 20 to 26 g/m 2 .
  • a wrapping paper with such porosity and amount of burning additive it is possible to increase the puff count of the smoking article.
  • the paper porosity of the base paper is 10 to 50 CU, e.g. 15 to 45 CU.

  • the paper porosity of the base paper is 40 to 50 CU, e.g. 43 to 47 CU, e.g. 45 CU. This further increases the puff count of the smoking article.
  • the burning additive is included in the base paper in an amount of 0.2 to 0.6 wt.-%, e.g. 0.3 to 0.5 wt.-% based on the dry weight of the base paper.
  • the total amount of burning additive is in an amount of 0.2 to 0.4 wt.-%, e.g. 0.3 wt.-%, based on the dry weight of the base paper.
  • the total amount of burning additive is in an amount of 0.3 to 0.5 wt.-%, e.g. 0.4 wt.-%, based on the dry weight of the base paper.
  • the total amount of burning additive is in an amount of 0.4 to 0.6 wt.-%, e.g. 0.5 wt.-%, based on the dry weight of the base paper. This further increases the puff count of the smoking article.

  • one or more of the plurality of burn-suppressing regions may be provided on a first surface of the base paper and the remaining of the plurality of burn-suppressing regions may be provided on a second, opposite surface of the base paper.
  • burn-suppressing regions are not further limited and may vary according to the specific requirements of the smoking article.
  • the burn-suppressing regions are in a form of stripes. In one embodiment all stripes are parallel to each other. In another embodiment at least two stripes are non-parallel to each other.
  • These burn-suppressing regions may contain additives that reduce the air diffusivity of the base paper.
  • the additives that may be applied to the wrapper may be any of those used in the art to reduce the ignition propensity of smoking articles.
  • the burn-suppressing regions contain at least one additive that reduces the air diffusivity of the base paper, where the additives are selected from the group consisting of alginates, polyvinyl alcohol, polyvinyl acetates, including partially hydrolysed derivatives and copolymers, modified and unmodified starches, cellulose derivatives, such as carboy-methyl cellulose, ethyl-cellulose and hydroxymethyl-cellulose, and combinations thereof.
  • the one or more additives may further comprise inorganic ions, such as phosphates, mono- or divalent metal salts, silicas and other agents known in the art to modify the burn rate, and combinations thereof.
  • the additives may be applied to the wrapping paper with a liquid carrier, which may be in the form of a solution, suspension, emulsion or a combination thereof.
  • the liquid carrier may be aqueous, non-aqueous or a combination thereof and may contain an emulsifying agent depending on the nature of the additives.
  • a suspension of additive may be applied within an aqueous carrier.
  • the aqueous carrier penetrates the base paper transporting the additive into its matrix. Once the carrier evaporates, the additive is left within the base paper matrix where it can reduce the air diffusivity either before or during the burning of the smoking article.
  • the liquid carrier is allowed to evaporate allowing the wrapping paper to dry and for the additive to set within the matrix of the base paper.
  • the air diffusivity of the burn-suppressing regions is 0.10 to 0.35 cm/s, e.g. 0.15 to 0.35 cm/s, or e.g. 0.10 to 0.30 cm/s, or e.g. 0.15 to 0.30 cm/s, or e.g. 0.15 to 0.25 cm/s, or e.g. 0.20 to 0.30 cm/s, or e.g. 0.20 cm/s to 0.25 cm/s.
  • the ratio of air diffusivity between the burn-suppressing regions and the non-burn-suppressing regions in the wrapping paper is in the range of 5% to 35%, e.g. 10% to 35%, or e.g. 15% to 35%, or e.g. 5% to 30%, or e.g. 10% to 30%, or e.g. 15% to 30%, or e.g. 10% to 25%, or e.g. 15% to 25%.
  • the fibrous material is a cellulosic fibrous material.
  • the present invention further relates to a smoking article comprising a wrapping paper as in the embodiments described above and in which the wrapping paper surrounds a charge, roll or column of smokable material to form a tobacco rod.
  • the burn-suppressing regions are in a form of stripes extending in a longitudinal direction of the tobacco rod and being spaced apart from each other in a circumferential direction of the tobacco rod.
  • the burn-suppressing regions are in a form of round annular bands extending in a circumferential direction of the tobacco rod and being spaced from each other in a longitudinal direction of the tobacco rod.
  • the positive effect of the present invention i.e. the combination of an increased number of puffs without changing the tobacco rod length or diameter is due to the specific combination of a paper porosity of 10 to 60 CU and at least one burning additive in an amount of 0.1 to 0.7 wt.-% as laid out above.
  • Cigarette A Cigarette B Tar 9.8 mg 10.0 mg Nicotine 0.80 mg 0.85 mg CO 9.0 mg 9.3 mg Puff count 6.8 8.1 LIP 100% 94% FASE 30% 8%
  • Two 84 mm low ignition propensity cigarettes were prepared with the same tobacco blend. These cigarettes had both a 57 mm tobacco rod attached to a 27 mm filter by a tipping paper. The filters were cut from the same filter rod and the tipping papers were cut from the same reel. The tobacco rod of cigarette C was wrapped in the prior art wrapping paper from example 1 (paper A), while cigarette D was wrapped in the wrapping paper according to the invention from example 1 (paper B).
