Definitions

  • the present invention relates to a tobacco unit for use in a making device for smoking articles.
  • the present invention relates to a tobacco unit having a preformed substantially rectangular cross section.
  • Such smoking articles are made using loose, fine-cut tobacco which the consumer rolls into a sheet of paper or inserts into a tube of paper, typically with the aid of a making device.
  • One of the disadvantages of such smoking articles is that smoking articles with variable quality, firmness and resistance to draw are produced, depending on the amount of loose tobacco used by the consumer and the consumer's skill.
  • EP-A-1 ,790,240 describes a continuous tobacco slab which may be used in a making device for smoking articles. Although the tobacco slab itself has a substantially uniform composition, a consumer still needs to handle the tobacco slab and select a suitable amount of the slab for use in a making device. In addition, the separation of the tobacco from the tobacco slab might lead to an undesired degradation of some of the tobacco fibres.
  • a tobacco unit for use in a making device for smoking articles, the tobacco unit comprising: a quantity of shredded tobacco suitable for making one smoking article; and an outer wrapper enveloping the shredded tobacco, the outer wrapper being open at both ends of the tobacco unit; wherein the tobacco unit is longitudinally extending and has a substantially rectangular cross section.
  • the tobacco unit may be arranged for use in a making device for smoking articles.
  • the tobacco of the tobacco unit is removed from the outer wrapper and inserted through an opening into a tobacco pressing chamber in the making device. Then the tobacco may be compressed into a cylindrical form, which may then be inserted into a prefabricated paper tube.
  • the prefabricated paper tube may be a filter-tipped paper tube.
  • the quantity of shredded tobacco in the longitudinally extending tobacco unit is preferably that quantity needed to fill one prefabricated paper tube.
  • the making device may be any manually operable smoking article making device having a tobacco pressing chamber suitable to receive the tobacco of the longitudinally extending tobacco unit, for example, the "Silver Tip" device manufactured by Gizeh Raucher loc GmbH, Germany.
  • the tobacco unit according to the invention has a number of advantages.
  • the tobacco unit produces a smoking article having a consistent and uniform quality, firmness and resistance to draw. Such consistency and uniformity is difficult to achieve by a consumer using loose tobacco.
  • the tobacco unit is convenient for a consumer, since the consumer does not need to handle loose tobacco.
  • the substantially rectangular shape of the longitudinally extending tobacco unit advantageously aligns with the opening of the tobacco pressing chamber in the making device.
  • the substantially rectangular cross section of the longitudinally extending tobacco unit also simplifies the distribution of tobacco in the tobacco pressing chamber of the making device and in a finished smoking article, compared with either loose tobacco or a cylinder, since the tobacco pressing chamber of the making device generally also has a rectangular opening corresponding to the substantially rectangular shape of the tobacco unit.
  • substantially rectangular cross section is used throughout the specification to indicate a cross sectional shape comprising two pairs of substantially parallel edges.
  • the corners of the rectangle may be curved.
  • the corners may have a radius, for example a radius with a length of up to 25% of the length of an edge. This may be, for example, due to resetting forces during production.
  • the substantially rectangular cross section is preferably substantially perpendicular to the longitudinal extent of the tobacco unit.
  • the outer wrapper is open at both ends of the tobacco unit and this refers to the ends (with a substantially rectangular shape) separated by the longitudinal extent of the tobacco unit.
  • the longitudinally extending tobacco unit comprises compressed shredded tobacco.
  • the shredded tobacco may be in cut filler form, for example blended, cased, cut and flavoured tobacco.
  • the strand length and strand width of the shredded tobacco is preferably substantially the same as fine cut used for the manufacture of roll-your-own and make-your- own smoking articles.
  • the term "strand" denotes a strip, shred, filament, rod or other elongate element. Processes and apparatus for producing shreds or strands of tobacco material are known in the art.
  • the length of the shreds or strands of tobacco material is preferably about 50 mm or less when uncurled.
  • the width of the shreds or strands of tobacco material may be between about 0.2 mm and about 0.9 mm.
  • the width of the shreds or strands of tobacco material is between 0.4 and about 0.9 mm, more preferably between about 0.5 mm and about 0.7 mm.
  • the longitudinally extending tobacco unit may comprise tobacco leaf lamina and tobacco leaf stems.
  • the longitudinally extending tobacco unit may comprise expanded tobacco. Expanded tobacco denotes tobacco that has been treated to increase its bulk volume.
  • the longitudinally extending tobacco unit may comprise reconstituted or homogenised tobacco material. Reconstituted or homogenised tobacco material denotes a material formed by agglomerating particulate tobacco.
  • the quantity of shredded tobacco in the longitudinally extending tobacco unit is suitable for making one smoking article.
  • the tobacco unit may comprise any desired quantity of shredded tobacco which is suitable for making one smoking article.
  • the particular quantity will depend, for example, on the size of smoking article to be produced from the tobacco unit. This will depend on the size of the making device for use with the tobacco unit.
  • the making device is arranged to be used with prefabricated paper tubes, which may be filter-tipped paper tubes.
  • the quantity of shredded tobacco in the longitudinally extending tobacco unit will depend on the size of the commercially available prefabricated cigarette paper tubes.

  • density used throughout the specification refers to the tobacco density in the tobacco unit or a continuous tobacco stream. The density can be measured, for example, by the ProScan 2 measuring device available from Hauni, Germany.
  • the average density of the longitudinally extending tobacco unit is calculated as the weight per unit volume of the tobacco unit.
  • the tobacco unit has a density sufficiently high that the shredded tobacco will retain its form (the longitudinally extending shape with a substantially rectangular cross section) when the outer wrapper is removed.
  • the density will be affected by various factors, including but not limited to, the filling capacity of the tobacco in the tobacco unit, the type or types of tobacco in the tobacco unit, the amount of expanded tobacco in the tobacco unit, and the quantity of any other non-tobacco components in the tobacco unit.
  • the density will be affected by how much the tobacco in the tobacco unit has been compressed or compacted.
  • the tobacco unit comprises between about 30% and about 100% of expanded tobacco, more preferably between about 70% and about 100% of expanded tobacco.
  • the average density of the longitudinally extending tobacco unit is the same as or slightly less than the average density of the tobacco in an industrially produced cigarette (which is about 240 mg/cm 3 ).
  • the average density of the longitudinally extending tobacco unit may be 10% lower than the average density of the tobacco in an industrially produced cigarette.
  • the average density of the longitudinally extending tobacco unit may be 20% lower than the average density of the tobacco in an industrially produced cigarette. This is so that, after compression of the tobacco of the tobacco unit, the resulting density is the same as the average density of the tobacco in an industrially produced cigarette.
  • the resulting density may be substantially the same as the average density of the tobacco of an industrially produced cigarette.
  • the length in the longitudinal direction of the tobacco unit is greater than the width or height of the tobacco unit.
  • the longitudinally extending tobacco unit may have any desired length but, preferably, the length of the tobacco unit is substantially equal to the length of the filling opening of the tobacco pressing chamber in the making device. This depends on the desired size of smoking article. In one embodiment in which the making device is arranged to produce conventional sized smoking articles, the length of the tobacco unit is between about 66 mm and about 69 mm. However, for different smoking article lengths, an appropriate length of the tobacco unit may be selected.
  • the smaller dimension of the tobacco unit's substantially rectangular cross section is the width and the larger dimension of the tobacco unit's substantially rectangular cross section is the height. That is, preferably, the height of the tobacco unit is greater than the width of the tobacco unit.
  • the ratio of height: width is 2:1 or less. More preferably, the ratio of height: width is between about 1 .2:1 and about 1 .7:1.
  • the longitudinally extending tobacco unit may have a substantially square cross section.
  • the longitudinally extending tobacco unit may have any desired width and height but, preferably, the width of the tobacco unit is substantially equal to the width of the filling opening of the tobacco pressing chamber in the making device. This depends on the desired size of smoking article. In one embodiment, the width of the tobacco unit is between about 5 mm and about 7 mm, more preferably about 6 mm. Alternatively, the width of the tobacco unit may be up to about 12 mm.
  • the height of the tobacco unit is not necessarily equal to any dimension of the tobacco pressing chamber in the making device.
  • the height of the tobacco unit is greater than the height of the tobacco pressing chamber in the making device.
  • this may allow the shredded tobacco to protrude from the top of the tobacco pressing chamber, when the shredded tobacco unit is positioned in the tobacco pressing chamber. A larger amount of tobacco may thus be incorporated when the tobacco is compressed into a cylinder. Since the width of the tobacco pressing chamber is fixed, such an arrangement is not possible with a tobacco unit having a circular cross section, since the height of the cylinder must equal its width.
  • the average density of the tobacco unit may be slightly less than the average density of the tobacco in an industrially produced cigarette.
  • the tobacco unit is about 69 mm in length, about 5 mm in width and about 10 mm in height.

  • the tobacco density at one or both ends of the longitudinally extending tobacco unit is between about 5% and about 20% higher than the tobacco density in the middle of the longitudinally extending tobacco unit.
  • the dense ends of the longitudinally extending tobacco unit reduce the likelihood of loose tobacco shreds dislodging from the tobacco unit, for example during handling and packing of the tobacco unit. This is advantageous since the outer wrapper is open at both ends of the tobacco unit. In addition, the dense ends may prevent tobacco shreds from escaping from the smoking article after manufacture.
  • the moisture content of the tobacco unit may be between about 14% and about 25% by weight of the tobacco unit.

  • tobacco unit 200 When tobacco unit 200 is used in the making device 100 of Figure 1 , operation is as follows. A consumer firstly removes the outer wrapper 203 from the shredded tobacco 201. Then, the consumer inserts shredded tobacco 201 into the tobacco pressing chamber 107 through opening 109. Since the length 1 19 of the tobacco unit 200 is substantially equal to the length 1 19 of the opening 109, and the width 121 of the tobacco unit 200 is substantially equal to the width 121 of the opening 109, this allows easy insertion of the shredded tobacco 201 into the chamber 107.

  • the height 123 of the tobacco unit 200 is larger than the height of the tobacco pressing chamber 107. Then, when the consumer inserts the shredded tobacco 201 into the tobacco pressing chamber 107, the shredded tobacco 201 protrudes above the opening 109 until lid 103 is closed onto base 101. Thus, a larger amount of tobacco can be incorporated into a finished smoking article. Since the width of the tobacco pressing chamber is fixed, such an arrangement is not possible with a tobacco cylinder, since the height of the cylinder must match its width. Since the tobacco pressing chamber 107 generally has a rectangular opening, use of a substantially rectangular tobacco unit 200 maximises efficiency of the making device.
  • the average density of the tobacco unit 200 is less than the average density of the tobacco of an industrially produced cigarette. This is so that, after the shredded tobacco 201 has been compressed into a cylinder in the tobacco pressing chamber 107, the resulting density is similar to the average density of the tobacco of an industrially produced cigarette.
