Definitions

  • the invention relates to a method for producing a tubular tobacco product and a tubular tobacco product and an aerosol-forming stick and an aerosol-generating device.
  • tobacco rod made of tobacco material
  • cigarette paper On the end of the tobacco rod usually a cylindrical filter (in the form of a plug) made of e. g. cellulose acetate with a wrapping made of filter paper (in the form of a plug wrap) is placed.
  • the filter and an edging area of the tobacco rod is wrapped by wrapping made of a special paper, for example of a tipping paper.
  • the tobacco material is made of natural leaf tobacco.
  • the material can be pre-treated or further processed for example by conditioning, stemming/stripping, drying, mixing, saucing, flavouring by spraying on flavouring substances and cutting.
  • final products from tobacco so called byproducts are generated from previous processes such as the threshing line.
  • the by-product generated from previous processes such as the threshing line, primary production and make & pack, can be collected and used in the manufacture of a tobacco sheet very similar to that of natural leaves of tobacco. The sheet is then cut into strips for ease of blending with other tobacco types.
  • the tobacco based components may include the leaf lamina, cut and rolled stem, reconstituted sheet and expanded tobacco.
  • the tobaccos stored in bales are broken up, cut into specific dimensions, and combined with other blend components such as casing and top dressing, and adjustment of the moisture content.
  • American blend cigarettes contain the four types of tobacco mentioned above plus reconstituted or homogenized sheet tobacco. This is made from tobacco dust, fines and particles, and leaf ribs and stems.
  • Reconstituted tobacco or homogenized sheet tobacco is a paper-like sheet approaching the thickness of tobacco laminae. It is made from tobacco dust, fines, and particles, and from ribs and stems.
  • Various additives may be incorporated. In the past, most of these "tobacco by-products" were wasted.
  • HnB products heat-not-burn tobacco products
  • These products use devices where tobacco is not burning. Instead of burning the tobacco, these tobacco products are heated and volatile constituents thereof are aerosolized.
  • the design of these products are manufactured so that they are similar to their combustible counterparts.
  • the tobacco product will be provided within a stick, whereby the stick can be placed within a heating element.
  • a typical HnB product will heat the tobacco placed within a special device to a lower temperature in comparison to temperatures reached within a conventional cigarette.
  • HnB tobacco products can have the form of so called HnB tobacco plugs.
  • HnB tobacco plugs are made of reconstituted tobacco. These are either made as solid cut tobacco plugs (like cigarettes), or tubes made of wrapped recon sheets (one or several layers). Reconstituted tobacco is limited in its absorbability of humectants and limits the product design (looking for a higher humectant content). Rolling sheet tobacco is technically challenging and limited in terms of speed and tobacco sheet characteristics. In this context, the use of extruding technology for producing smokeable devices is known from the state of the art. This approach is often combined with a focus on tobacco material itself.

  • the article preferably has at least one air-permeable plug of readily ignitable material blocking the passage at one or both ends.
  • the tobacco-containing mass may include non-tobacco filler particles, such as carbon or clays, and the plug may contain a flavorant.
  • the articles may be made by shaping a mixture of combustible tobacco material with a volatile liquid, for example a mixture of water and glycerol or propylene glycol, under pressure into a discrete coherent mass, preferably by extrusion, forming a passage through the mass, and drying the mass to a porosity and density such as to substantially occlude gas flow there through but to support combustion when ignited.

  • this document does not disclose a tubular tobacco product comprising at least one hollow bore extending along the longitudinal axis of the tubular tobacco product.
