Definitions

  • the present invention relates to a sheet of smokeable material.
  • Roll your own tobacco products are tobacco products, such as smoking articles, which are prepared by the consumer.
  • WO 2008/056099 A1 (BRITISH AMERICAN TOBACCO CO [GB]; FIEBELKORN RICHARD [GB]) 15 May 2008 ( 2008-05-15 ) describes a roll-your-own smoking article made from a laminate of tobacco and paper.
  • WO 2015/082653 A1 (PHILIP MORRIS PRODUCTS SA [CH]) 11 June 2015 ( 2015-06-11 ) describes rods comprising a co-laminated sheet comprising an aerosol-forming material and a thermally-conductive material.
  • a laminate comprising a layer of tobacco material and a support sheet as defined by claim 1.
  • the tobacco material comprises fibrous material.
  • the fibrous material comprises tobacco.
  • the tobacco material comprises reconstituted tobacco.
  • the support sheet comprises paper.
  • the tobacco material additionally comprises glycerol, polyethylene glycol, and/or propylene glycol.
  • the tobacco material comprises from 12 wt % water to 16 wt % water.
  • the permeable structure is uniform across the entire thickness of the tobacco material.
  • a portion of the support sheet extends beyond an edge of the layer of tobacco material.
  • the portion of the support sheet extending beyond an edge of the layer of tobacco material does not extend along the full length of the layer of tobacco material.
  • a method of manufacturing a laminate according to the first aspect of the invention comprising the steps of preparing a layer of tobacco material having a rough surface and adhering the layer of tobacco material to a support sheet.
  • the layer of tobacco material according to the second aspect of the invention comprises fibrous material.
  • the fibrous material comprises tobacco.
  • a package containing a laminate according to the first aspect of the invention there is provided a package containing a laminate according to the first aspect of the invention.
  • a laminate according to the first aspect of the invention to prepare a smoking article.
  • a smokeable product comprising a laminate according to the first aspect of the invention.
  • Conventional roll your own tobacco products are prepared by the user through the use of loose cut tobacco and rolling paper.
  • the consumer typically measures out cut tobacco, spreading it evenly along the length of the paper, forming a channel with the paper such that the tobacco is contained in the bottom of the channel, manipulating the tobacco by rolling paper between the fingers and thumbs to form a substantially cylindrical rod of tobacco, rolling the paper around the tobacco and sticking a free edge of the paper to the outer surface of the cylindrical article that is produced to form a smokeable cigarette.
  • This method of forming a cigarette requires separate handling of tobacco and papers and results in cigarettes with varying quantities of tobacco. This provides the consumer with an inconsistent smoking experience. In addition, there is also risk of losing tobacco through spillage due to the separate handling of the tobacco and papers.
  • the laminate according to the present invention comprises a layer of tobacco material and a support sheet.
  • the layer of tobacco material comprises a rough surface so as to provide a permeable structure through which air may be drawn when the laminate is rolled or folded into a smoking article.
  • the laminate is rolled or folded at least some of the surface of the layer of tobacco material contacts the support sheet.
  • the presence of the rough surface provides channels either through the tobacco material or between the tobacco material and the adjacent support sheet through which air may be drawn.
  • tobacco material refers to any smokeable material and includes, but is not limited to any part, e.g. leaves, leaf portions, flowers, roots, and stems, of any member of the genus Nicotiana and blends thereof, reconstituted tobacco, tobacco substituents, tobacco derivatives, dried fruits or herbs, and the like.
  • the tobacco material comprises reconstituted tobacco.
  • the layer of tobacco material has a rough surface.
  • the layer of tobacco material has an uneven or irregular surface.
  • the rough surface may be formed when preparing the layer of tobacco material. For example, pressing the layer of tobacco material either longitudinally or laterally may provide a rough surface. For example, strands of tobacco material may be laid onto the paper and compressed, forming an irregular surface.
  • the rough surface may be created by the presence of a fibrous material.
  • larger particles or fibres may be distributed either uniformly or randomly across the surface of the layer of tobacco material to provide a rough surface comprising a series of channels or pathways within the tobacco material through which air may pass. These pathways may be within the layer of tobacco material or they may be formed between the surface of the tobacco layer and an adjacent layer when rolled or folded.
  • relatively larger particles of fibres may be present within the layer of tobacco material. Their greater size prevents the tobacco material from forming a smooth surface and therefore creates a rough surface.
  • the fibrous material may be from a cellulosic source, such as tobacco, reconstituted tobacco (including, for example, so called Fibex), wood or paper, waste lamina, or other sheet material such as smokeable filler material comprising a blend of non-combustible inorganic filler material, a binder, and an aerosol generating means.
  • a cellulosic source such as tobacco, reconstituted tobacco (including, for example, so called Fibex), wood or paper, waste lamina, or other sheet material such as smokeable filler material comprising a blend of non-combustible inorganic filler material, a binder, and an aerosol generating means.
  • the fibrous material comprises a smokeable material, such as cut stems of tobacco.
  • the tobacco material may be flexible in order for the laminate to be rolled or folded without the layer of tobacco material cracking, splintering or in any other way separating from the support sheet.
  • the layer of tobacco material may comprise an additive which enables the layer of tobacco material to be manipulated on the support sheet without breaking.
  • various gums and pectins may be used as a binder when preparing the layer of tobacco material to assist with maintaining the integrity of the layer of tobacco material.
  • Preferred binders are natural pectins, such as fruit, citrus, tobacco pectins, guar gums such as hydroxyethyl guar and hydroxypropyl guar, locust bean gums, such as hydroxyethyl and hydroxypropyl locust bean gum, alginate, starches, such as modified or derivitised starches, celluloses, such as methyl, ethyl, ethylhydroxymethyl and carboxymethyl cellulose, tamarind gum, dextran, pullalon, konjac flour, xanthan gum, and the like.
  • the tobacco material may additionally contain water.
  • the tobacco material may contain from about 5 wt % water to about 20 wt % water.
  • the tobacco material contains from about 12 wt % water to about 16 wt % water.
  • the layer of tobacco material may comprise further additional additives, such as flavours and/or flavourants.
  • flavours and/or flavourants refer to materials which, where local regulations permit, may be used to create a desired taste or aroma in a product for adult consumers.
  • extracts e.g., licorice, hydrangea, Japanese white bark magnolia leaf, chamomile, fenugreek, clove, menthol, cacao, Japanese mint, aniseed, cinnamon, herb, wintergreen, cherry, berry, peach, apple, Drambuie, bourbon, scotch, whiskey, spearmint, peppermint, lavender, cardamon, celery, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, cassia, caraway, cognac, jasmine, ylang-ylang, sage, fennel, piment, ginger, anise, coriander, coffee, or a mint oil from any species of the genus Mentha), flavour enhancers, bitterness receptor site blockers, sensorial receptor site activators or stimulators, sugars and/or sugar substitutes (e.g., sucralose, acesulfam
  • the layer of tobacco material may comprise a humectant, such as glycerol, polyethylene glycol, and propylene glycol.
  • a humectant such as glycerol, polyethylene glycol, and propylene glycol.
  • the rough surface may extend across the entire thickness of the layer of tobacco material.
  • the rough surface provides a minimum resistance no matter how tightly the laminate is rolled or folded.
  • the rolled laminate provides low draw resistance for consumer preference.
  • the pressure drop of the rolled laminate is from about 30 mm WG (Water Gauge) to about 200 mm WG.
  • the pressure drop is from about 95 mm WG to about 155 mm WG.
  • the pressure drop is 0.2 to 1.5 mm WG per mm length of the rolled laminate, preferably 0.5 to 1.0 mm WG per mm.
  • the thickness of the layer of tobacco material is from about 0.5 mm to about 3 mm.
  • the laminate comprises a support sheet.
  • sheet is intended to refer to any material suitable for supporting tobacco and capable of being wrapped around itself.
  • the support sheet may be made from any sheet suitable for circumscribing a tobacco rod of a smoking article.
  • the support sheet may comprise paper. Examples include, but are not limited to, standard wrapping paper as used for roll your own or pre-formed cigarettes and reconstituted tobacco sheets.
  • the material may have a papery texture, or it may feel rough, moist or be otherwise distinguishable from standard papery textures.
  • the support sheet may be a sheet comprising any reconstituted material, including reconstituted tobacco material, or a sheet comprising chalk, or a sheet comprising a blend of inorganic filler material, binder, and aerosol generating means.
  • the layer of tobacco material covers the whole area of the support sheet except for at least one strip which is free of tobacco.
  • the tobacco free strip is located close to or along an edge.
  • at least one of these tobacco-free edges may have an adhesive applied thereto.
  • the laminate is rolled to form a smoking article. When the laminate is rolled the tobacco free area along the edge of the support sheet may be adhered to the outside surface of the smoking article to retain the laminate in a substantially cylindrical configuration.
  • the layer of tobacco material may cover the whole area of the support sheet except a strip located along the longitudinal edge.
  • the laminate may be more easily rolled into a smoking article.
  • a pack is provided containing at least one laminate according to the present invention.
  • a pack may contain numerous laminates which can be rolled or folded into a smoking article.
