Definitions

  • the present invention relates to a novel reconstituted tobacco sheet, related manufacturing methods, and uses thereof.
  • the reconstituted tobacco sheet according to the present invention finds particular application in the manufacture of tobacco cut filler for smoking articles.
  • One of the known methods is to ground tobacco stems to a fine powder and then mix the tobacco stems with tobacco dust, guar gum, and water to form an aqueous slurry.
  • This aqueous slurry may be then cast and dried to form a reconstituted tobacco sheet.
  • this type of reconstituted tobacco sheet has a low tensile strength.
  • a non-tobacco cellulose for example in the form of wood cellulose fibres, is usually added to the slurry as a binder. But, the presence of a non-tobacco ingredient is generally undesirable due to the increase in cost and negative impact on flavour attributed to this ingredient.
  • tobacco materials are mixed in an agitated tank with water to obtain a pulp.
  • the soaking and mixing of the tobacco in the tank with water causes the water soluble components of the tobacco to dissolve into the liquid, creating a tobacco-flavoured liquid or tobacco juice.
  • This tobacco-flavoured liquid subsequently needs to be separated from the non- soluble portion of the tobacco before further processing.
  • the pulp may be compressed or processed using a centrifuge to remove the tobacco-flavoured liquid containing the water-soluble components.
  • the non-water-soluble portion then subsequently undergoes a paper-making process (for example, using a Fourdrinier machine) to form a base web.
  • a Fourdrinier machine typically includes a forming section, a press section and a drying section.
  • the forming section which comprises a plastic fabric mesh conveyor belt often referred to as a "wire" as it was once woven from bronze, the pulp is drained to create a continuous paper web. Subsequently, this wet web is fed onwards to the press section, where the excess water is squeezed out of the web. Finally, the pressed web is conveyed on through a heated drying section.
  • the tobacco-flavoured liquid is also subjected to further processing using an evaporation operation to form a concentrated liquor, which may be added back to the base web in order to at least partly restore flavour to the base web that would otherwise be lost.
  • WO 2009/037304 discloses a smoking article comprising a patch of a material that allows a more free passage of smoke than does the tobacco of the smoking article.
  • the patch may, for example, be arranged underneath the outer wrapper, and may be formed from any material having the appropriate combustion and compositional properties for inclusion in a smoking article and providing the required low-resistance passage for smoke propagation. This provides a preferential low resistance path through the smoking article for the smoke, such that the smoke is delivered more efficiently to the consumer.
  • the provision of an open- structured material in the smoking article is meant to increase the static burn rate of the smoking article.
  • suitable materials for the patch include fibrous sheet materials having a sufficiently open structure, such as a cellulosic sheet material.
  • the patch may comprise corrugated material, such as corrugated paper or cardboard.
  • a tobacco-containing sheet material such as a web of reconstituted tobacco may be used, the web having a structure that is inherently suitable for providing low resistance to the flow of smoke.
  • WO 2009/037304 teaches using reconstituted tobacco as such, not quite as a component of the cut filler forming the tobacco rod of a smoking article, but rather as a further structural element of the smoking article that is either positioned over the tobacco rod before circumscribing the rod with paper wrapper, or adhered to an inner surface of the paper wrapper before winding the paper wrapper around the rod.
  • a corrugated tobacco sheet comprising a corrugated medium comprising a plurality of flutes and having a first and a second side; and at least one liner.
  • a first liner adheres to the first side of the corrugated medium and the corrugated medium and the liner are formed from a web of reconstituted tobacco.
  • a corrugated tobacco sheet comprising a corrugated medium comprising a plurality of flutes and having a first and a second side, the corrugated medium being formed from a web of reconstituted tobacco.
  • a tobacco cut filler comprising portions of one such corrugated tobacco sheet, the portions having a mean cut width from about 0.7 millimetres to about 1 .5 millimetres.
  • a tobacco product comprising one such corrugated tobacco cut filler.
  • a method of manufacturing a corrugated tobacco web comprising providing a first web of reconstituted tobacco; and shaping the first web of reconstituted tobacco into a corrugated configuration with a plurality of flutes to form a corrugated medium having a first side and a second side.
  • web of reconstituted tobacco sheet is used to refer to a web of substantially uniform thickness that may be produced by the rolling or casting of an aqueous slurry or pulp formed from tobacco by-products such as tobacco stems, tobacco stalks, leaf scraps, and tobacco dust produced during the manufacturing process, for example by one of the methods known in the art described above.
  • corrugated is used throughout the present specification to describe a web material, such as a web or sheet of reconstituted tobacco, that has been shaped into folds or parallel and alternating ridges and grooves.
  • the term "flute height” shall be construed as identifying the vertical distance measured from trough to peak in a flute.
  • the term “flute height” shall identify a distance equalling twice the amplitude of the sine function. In other words, it is twice the peak deviation of the sine wave function from zero.
  • the term "flute pitch” shall be construed as identifying the horizontal distance measured between adjacent flute troughs.
  • the term “flute pitch” shall substantially identify the distance between consecutive maxima of the sine wave function.
  • tobacco product or "tobacco products” are used throughout this specification to refer to both combustible smoking articles and to smoking articles in which an aerosol forming substrate, such as tobacco, is heated rather than combusted.
  • Combustible smoking articles such as cigarettes, generally comprise shredded tobacco (usually in cut filler form) surrounded by a paper wrapper forming a tobacco rod.
  • the shredded tobacco can be a single type of tobacco or a blend of two or more types of tobacco.
  • a cigarette is employed by a consumer by lighting one end thereof and burning the shredded tobacco rod. The consumer then receives mainstream smoke by drawing on the opposite end (mouth end or filter end) of the cigarette.
  • the aerosol is generated by heating the aerosol forming 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 forming substrate.
  • volatile compounds are released from the aerosol forming 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.
  • filling power of tobacco cut filler, reference is made throughout this specification to the ability of the tobacco cut filler to form a firm tobacco rod with given moisture content. A high filling power indicates that a lower weight of tobacco is required to produce a tobacco rod than is required with a tobacco of lower filling power.
  • the corrugated tobacco web of the invention is coupled with at least one substantially flat tobacco web.
  • the overall mechanical strength and resilience of the sheet is increased, with respect to existing reconstituted tobacco sheets, whilst preserving a satisfactory level of flexibility.
  • the resulting corrugated tobacco sheet can conveniently be formed into a roll, for example for ease of shipping and transporting.
  • resilience can be further increased.
  • Significant rigidity levels may be achieved, which may be desirable in view of certain mechanical operation that the resulting corrugate tobacco sheet may be subjected to, for example in the manufacturing of smoking articles.
  • the corrugated tobacco sheet of the present invention may be manufactured from a conventional reconstituted tobacco web using manufacturing equipment known from the cardboard industry.
  • different types of reconstituted tobacco webs can be used at once, such as reconstituted leaf web and cast leaf web obtained from different manufacturing methods and therefore having different characteristics.
  • flavour characteristics can also be advantageously tailored.
  • a product that is improved from a mechanical viewpoint and that also satisfies specific taste requirements may conveniently be manufactured.
  • the reconstituted tobacco webs may comprise one or more binders, such as guar gum, or a flavourant composition, or a combination of the two.
  • binders such as guar gum, or a flavourant composition, or a combination of the two.
  • Such flavourant composition might include particles of a sorbent or cellulosic material impregnated with liquid flavourant or particulate material such as herbaceous material, or any combination thereof.
  • Flavourant materials include, but are not limited to, materials that contain natural or synthetic menthol, peppermint, spearmint, coffee, tea, spices (such as cinnamon, clove and ginger), cocoa, vanilla, fruit flavours, chocolate, eucalyptus, geranium, eugenol, agave, juniper, anethole and linalool.
  • flavourant materials may include essential oils, or a mixture of one or more essential oils.
  • An "essential oil” is an oil having the characteristic odour and flavour of the plant from which it is obtained. Suitable essential oils include, but are not limited to, eugenol, peppermint oil and spearmint oil.
  • the flavourant material comprises menthol, eugenol, or a combination of menthol and eugenol.
  • the term “herbaceous material” is used to denote material from an herbaceous plant.
  • An “herbaceous plant” is an aromatic plant, the leaves or other parts of which are used for medicinal, culinary or aromatic purposes and are capable of releasing flavour into smoke produced by a smoking article.
  • Herbaceous material includes herb leaf or other herbaceous material from herbaceous plants including, but not limited to, mints, such as peppermint and spearmint, lemon balm, basil, cinnamon, lemon basil, chive, coriander, lavender, sage, tea, thyme and carvi.
  • mints such as peppermint and spearmint
  • lemon balm basil
  • cinnamon lemon basil
  • chive coriander
