    Abstract: Tobacco is reconstituted to provide a product of tobacco-filler size particles. Particulate tobacco, from 5 to 10 weight percent of starch, up to 10 weight percent binder and water are fed to an extruder, the operating conditions being such that in the sheet form extrudate water flashes off to steam, thus to expand the extrudate. Further, the cross-section of the extrudate when exiting the orifice of the extruder expands to a cross-section greater than that of the orifice of the extruder. After being cooled, the extrudate is cut to particle size. The particles, each of which comprises a cellular interior and a skin at two opposite sides, can be used as or in cigarette filler.

The smoking article contains a plurality of strands that are adhered to one another so as to form passageways between the strands, the passageways extending generally along the longitude of the smoking article. The configuration of the strands and passageways provides sufficient heat transfer area and/or residence time for the smoke drawn by a smoker to cool to an acceptable level.

  • Patent number: 4625737
    Abstract: A substantially cylindrical foamed, extruded, tobacco-containing smoking article and a method of making the article. The article has properties substantially equivalent to a conventional cigarette. It contains from about 5 to about 98 wt. % of particulate tobacco, from 0 to about 60 wt. % of particulate filler, from about 2 to about 40 wt. % of a cellulosic binder selected from among hydroxypropyl cellulose, carboxymethyl cellulose, and its sodium, potassium and ammonium salts, cross-linked carboxymethyl cellulose, and its sodium, potassium and ammonium salts, hydroxyethyl cellulose, ethyl hydroxyethyl cellulose, hydroxypropyl methyl cellulose, methyl cellulose, ethyl cellulose, and mixtures thereof, and from about 5 to about 20 wt. % of water. The article has a density within the range of from about 0.05 to about 1.5 g/cc. The method of making such articles comprises the step of (a) dry blending the tobacco particles having an OV value of from about 3 to about 20% with from 0 to about 60 wt.

  • Patent number: 4617945
    Abstract: Process for flavoring tobacco by mixing dry cut tobacco with one or more micro-encapsulated flavors as well as with an aqueous adhesive solution containing such quantity of water that said quantity may at least be adsorbed for the most part by the tobacco, continuing the mixing operation till a dry or almost dry product is obtained and then, if necessary, subjecting the obtained product to a drying operation respectively reduction operation.

  • Patent number: 4611608
    Abstract: A process for utilizing tobacco dust by affixing it to cut, shredded or otherwise comminuted tobacco, reconstituted tobacco or tobacco substitute by thoroughly mixing tobacco dust, a powdered water soluble hydrocolloid, optionally an organic solvent, the comminuted tobacco, reconstituted tobacco or tobacco substitute, water or an aqueous solution of the hydrocolloid and optionally an additional quantity of the comminuted tobacco, reconstituted tobacco or tobacco substitute and continuing the mixing until a dry or almost dry product is obtained. The water soluble hydrocolloid may partly or completely be replaced by micro-encapsulated flavors, so that flavored tobacco products are obtained.

  • Patent number: 4545392
    Abstract: A smokeless tobacco product is disclosed which contains cut or otherwise comminuted tobacco treated with a particulated gum composition that adheres as a discontinuous coating to the surface of the tobacco. The gum composition provides improved "gathering" characteristics and other benefits when the treated smokeless tobacco product is placed in the mouth of the consumer of such products.

  • Patent number: 4497331
    Abstract: A tobacco product with a high specific volume and particularly suited for use as cigarette or cigar filler produced by laminating together two sheets of reconstituted tobacco sheet under conditions so that the resulting laminate, after shredding, contains shreds in which the plies are only partly adhered and partly separated, whereby a filler having substantially increased filling power is produced as compared with conventional reconstituted tobacco sheet.

  • Patent number: 4489738
    Abstract: This invention concerns the use of specific coatings that are applied to the paper wrapper that encloses the cigarette's smoking medium for limiting in a predictable manner the free burning time of the treated cigarette, or controlling the lapsed time prior to self-extinguishment after being lit and left unattended. The coating materials are generally identified as hydrophylic colloids or aqueous-soluble polymers, that are deposited singly or as mixtures from aqueous media, and are represented by locust bean gum, pectin, sodium carboxymethylcellulose, and guar gum, forming adherent, non-tacky, flexible coatings on the paper housing substrates, and significantly altering the burning characteristic of the resultant cigarettes. Comparable behaviors are obtained, for equivalent weight percentages of the deposited solids, by either precoating the portion of paper wrapper that subsequently encloses the charge of tobacco or by post-treatment of the external surface of the assembled cigarette.

  • Patent number: 4341228
    Abstract: A method for employing tobacco dust in a paper-making process for the preparation of reconstituted tobacco is disclosed. The method for employing the tobacco dust comprises admixing tobacco dust with a bonding material to form a mixture, treating the mixture to form agglomerated particles, admixing the agglomerated particles with a tobacco-parts slurry and then forming the slurry into a sheet by means of a paper-making process, drying and then shredding the resultant reconstituted tobacco sheet. The smoking material obtained by such method is also described.
