Patent number: 8869805Abstract: Smoking articles having reduced ignition proclivity characteristics are disclosed. Smoking articles include a paper wrapper that is treated with a film-forming composition. The film-forming composition forms treated discrete areas on the wrapper. The treated discrete areas reduce ignition proclivity properties of the smoking article made with the wrapper. The film-forming composition contained a film-forming material blended with a burn promoting agent in the absence of a burn retardant. In one embodiment, for instance, the film-forming composition consists essentially of a film-forming material and a burn promoting agent. Various advantages and benefits are realized by blending a film-forming material with burn promoting agent without also incorporating a burn retardant into the composition.Type: GrantFiled: June 1, 2007Date of Patent: October 28, 2014Assignee: Schweitzer-Mauduit International, Inc.Inventor: Joseph T. Wanna

Patent number: 8151806Abstract: Smoking articles having reduced Hoffmann analytes contained in the mainstream smoke is disclosed. In one embodiment, an alginate composition is applied to a wrapper that is incorporated into a smoking article. The alginate composition causes a significant reduction in at least certain of the Hoffmann analytes that are generated when the smoking article is smoked. The alginate composition may be applied so as to cover a substantial portion of the surface area of the wrapper in one embodiment. In another embodiment, the alginate composition is applied as a single band to the paper wrapper so to cover a substantial portion of the distal end of the smoking article.Type: GrantFiled: February 7, 2005Date of Patent: April 10, 2012Assignee: Schweitzer-Mauduit International, Inc.Inventor: Joseph T.

Patent number: 7308898Abstract: A bandcast tobacco sheet for use in a cigarette includes from about 5 to 15% by weight of wood pulp, from about 15 to 40% by weight of binder and from about 15 to 40% by weight of tobacco. A humectant may be included up to 30% by weight and an additive, such as menthol, may be added to up about 30% by weight. A bandcast tobacco sheet is used in elongated strips along the outer surface of a tobacco rod between the tobacco rod and an inner surface of an outer wrap of cigarette paper.Type: GrantFiled: March 26, 2004Date of Patent: December 18, 2007Assignee: R.J. Reynolds Tobacco CompanyInventors: Luis Monsalud, Jr., Joseph T. Wanna, Douglas R. Hicks

Patent number: 7051739Abstract: A cigarette with burn rate modification is described. The cigarette has a partial double wrap design and incorporates an inner wrap material which extends partially around the interior portion of the outer wrapper of a cigarette. The inner wrap can be a single element or can be a plurality of strips which extend coaxially along the tobacco column and which affect the burn rate of the cigarette. The partial inner wrap material exhibits a low porosity and forms zones of high diffusion and low diffusion along the length of the tobacco rod. These zones may be singular or may be alternating and are coaxial. The low diffusion zones are aligned with the inner wrap material.Type: GrantFiled: January 14, 2003Date of Patent: May 30, 2006Assignee: R.J. Reynolds Tobacco CompanyInventors: Joseph T. Wanna, Douglas R. Hicks

Patent number: 6705325Abstract: A cigarette making machine for manufacturing of a cigarette with burn rate modification is described. The cigarette maker allows for mounting of a special bobbin of material which is different in size and width of a normal wrapper bobbin and feeds both the outer wrap web of material and narrower inner wrap web of material to the garniture. A slitting device may be utilized to cut the inner wrap web of material into a plurality of individual strips which are placed adjacent the outer wrap web of material in the garniture area of the maker. The inner wrap web of material may derive from a transverse wound bobbin in order to store large linear amounts of inner wrap web material.Type: GrantFiled: March 14, 2003Date of Patent: March 16, 2004Assignee: Brown & Williamson Tobacco CorporationInventors: Douglas R.
