  • Patent number: 8291919
    Abstract: A tobacco product is formed by perforated cigar or shell, the shell comprising a sheet of material with an intermediate sheet, the sheet comprising tobacco leaves and/or homogenized tobacco paper. The cigar or shell is packaged for shipment to an end user or consumer. The cigar or shell remains in the rolled, shaped tube form inside the package. After the cigar or shell is removed from the package, a consumer can fill the cigar or shell with crushed tobacco leaves or other tobacco filler material of a favorite blend, thereby eliminating some steps in the making of a “roll-your-own” tobacco product. A liquid can be added to the cigar or shell to moisturize same. The liquid can include flavoring.

  • Publication number: 20120167902
    Abstract: A smokeless tobacco system includes a container including a plurality of preformed smokeless tobacco products configured to generally retain their shape and integrity. One or more of the preformed smokeless tobacco products are compressed between a lid and a base of the container to hinder movement of the one or more preformed smokeless tobacco products within the container. Each preformed smokeless tobacco product can include a moist smokeless tobacco in combination with a selected binder such that the final product is configured to have material properties providing improved handling, an improved mouth feel, and a satisfying flavor profile. A method of forming and packaging the preformed smokeless tobacco products includes depositing shaped smokeless tobacco bodies into the container and closing the container prior to a relaxation of the shaped smokeless tobacco bodies into preformed smokeless tobacco products.

  • Patent number: 7900639
    Abstract: A reconstituted tobacco material incorporates an exogenous tocopherol or derivative thereof, such as in the amount of at least about 0.1 weight percent. A tobacco blend can be formed by combining reconstituted tobacco material incorporating such an additive with one or more additional tobacco materials, such as burley tobacco, Oriental tobacco, and flue-cured tobacco. A smoking article, such as a cigarette, contains such a reconstituted tobacco, as part of the smokable material, as part of tobacco paper wrapping material, or as part of a reconstituted tobacco-containing filter element. The invention also provides a method of forming reconstituted tobacco material wherein a tocopherol or derivative thereof is added to the tobacco material, either by adding the tocopherol to an aqueous extract or water insoluble pulp formed during the reconstituted tobacco process or by adding the tocopherol to the solid reconstituted tobacco sheet after the aqueous extract and pulp are recombined.
