Definitions

  • the present invention relates to tobacco, and in particular, to tobacco formulations suitable for use in a smokeless manner, and to the handling and use of tobacco that is in a smokeless form.
  • Cigarettes, cigars, little cigars and pipes are popular smoking articles that employ tobacco in various forms.
  • Smoking articles are tobacco products that are used by heating or burning tobacco, and aerosol (e.g., smoke) is inhaled by the smoker.
  • Representative manners or methods that have been proposed for the packaging of tobacco products, including cigarettes and cigars, are set forth in U.S. Pat. Nos. Des 368,221 to Montague ; 1,886,115 to Muller ; 3,371,775 to Butler ; 3,967,730 to Driscoll et al. ; 4,852,734 to Allen et al. ; 5,139,140 to Burrows et al. ; 5,333,729 to Wolfe ; 5,542,529 to Hein, III et al. ; 5,938,018 to Keaveney et al. and 7,014,039 to Henson et al.
  • Tobacco also may be enjoyed in a so-called "smokeless" form.
  • smokeless tobacco products are employed by inserting some form of processed tobacco or tobacco-containing formulation into the mouth of the user.
  • Snuff typically is formulated in "moist" or “dry” forms.
  • snuff products are manufactured in Europe, particularly in Sweden, by or through companies such as Swedish Match AB, Fiedler & Lundgren AB, Gustavus AB, Skandinavisk Tobakskompagni A/S and Rocker Production AB.
  • Snus products available in the U.S.A. are marketed under the tradenames Camel Snus Frost, Camel Snus Original and Camel Snus Spice by R. J. Reynolds Tobacco Company.
  • Representative smokeless tobacco products also are marketed under the tradenames Oliver Twist by House of Oliver Twist A/S; Copenhagen, Skoal, SkoalDry, Rooster, Red Seal, Husky, and Revel by U.S.
  • Exemplary manners for providing various types of tobacco products for distribution to consumers have been proposed in U.S. Pat. No. 3,696,917 to Levi ; PCT WO 2004/095959 to Arnarp et al. and PCT WO 2005/016036 to Bjorkholm .
  • Equipment for packaging tobacco has been commercially available, and representative equipment has been available as FPP 210 Pouch Packer from Schur Flexible Benelux.
  • WO 03/053175 A2 discloses a composition for use in the oral cavity comprising tobacco and/or a tobacco substitute encapsulated in a membrane material comprising one or more membranes at least one of which being water permeable and water-insoluble.
  • WO 96/14763 A1 discloses packed cigarettes characterized that each package contains only one single cigarette.
  • Smokeless tobacco products are packaged for distribution, sale and use in a variety of ways. Chewing tobacco has been packaged in pouches, foil bags and metal containers. Snus types of products have been packaged in tins, "pucks” or “pots” that are manufactured from metal or plastic. In certain circumstances, smokeless tobacco products are refrigerated prior to sale, typically for the purpose of prolonging the freshness and moisture content thereof. For example, smokeless tobacco products, particularly moist tobacco products, can be refrigerated in order to avoid or retard absorption of contaminants that provide an undesirable flavor or odor to the product, avoid or retard the development discoloration or staining of the product, and to avoid or retard the activity of biologically active microorganisms.
  • smokeless tobacco products and typically moist snuff types of products, can be refrigerated to retard the effects of enzymatic and other biological activities, pH changes, oxidation, and other effects that have a tendency to shorten product shelf-life or stability.
  • the present invention relates to a smokeless tobacco product.
  • the product includes a smokeless tobacco composition or formulation.
  • the smokeless tobacco formulation includes particles or pieces of tobacco, and may include other ingredients, such as salts, sweeteners, binders, colorants, pH adjusters, fillers, flavoring agents, disintegration aids, antioxidants, humectants, and preservatives.
  • the moisture content of the particles of the tobacco may vary.
  • Certain smokeless tobacco products have the form of tobacco compositions or formulations that result from casting or otherwise forming a slurry incorporating tobacco material and other components as a film or sheet.
  • Certain smokeless tobacco products have the form of tobacco compositions or formulations that result from pressing, extruding or otherwise forming a mixture incorporating tobacco material and other components into a desired shape.
  • the tobacco formulation can be contained within a container, such as a pouch or bag, such as is the type commonly used for the manufacture of snus types of products (e.g., a sealed, moisture permeable pouch that is sometimes referred to as a "portion").
  • a representative moisture permeable pouch can be composed of a "fleece” type of material.
  • the tobacco formulation is in turn contained within a package.
  • the package is sealed tightly, and is composed of a suitable material, such that the atmospheric conditions within that sealed package are modified and/or controlled; that is, the sealed package can provide a good barrier that inhibits the passage of compositions such as moisture and oxygen therethrough; in addition, the atmosphere within the sealed package can be further modified by introducing a selected gaseous species (e.g., nitrogen, argon, or a mixture thereof) into the package prior to sealing or by drawing a vacuum therein (vacuum sealing).
