  • Patent number: 10080385
    Abstract: A smoking article provides one or more sheets of material that can be rolled and packaged, at least one sheet including cellulose. In one embodiment, cellulose and tobacco sheet material are separately rolled layers that can optionally be wrapped around a form casing (or pre-rolled inside) and then packaged. In another embodiment, the sheet is a laminated sheet of tobacco and cellulose layers that can be optionally wrapped around (or pre-rolled inside) a form casing. These sheets can be filled with custom tobacco to make one or more new cigars for an end user. In another embodiment, a complete cigar filled with tobacco material can be disassembled by an end user to produce tobacco and cellulose sheets, enabling the end user to form two new cigars using his or her own custom tobacco.

  • Patent number: 10028525
    Abstract: A process for reducing the permeability of a paper wrapper used in the construction of a smoking article is disclosed. The paper wrapper is treated with a film-forming composition that forms treated discrete areas on the wrapper. The treated discrete areas have a permeability within a predetermined range sufficient to reduce the ignition proclivity properties of a smoking article made with the wrapper. In accordance with the present invention, the film-forming composition contains a film-forming material. The film-forming material has a relatively low viscosity. In this manner, the film-forming composition can have a relatively high solids content and still be applied to the wrapper using conventional techniques, such as by using a gravure printer.
