Patent number: 5183062Abstract: A cigarette includes a longitudinally segmented combustible fuel element, and a substrate carrying tobacco extract and glycerin positioned physically separate from the fuel element. The substrate is a gathered paper-type material, and is positioned in a spaced apart relationship from the fuel element. The fuel element is composed of a carbonaceous material and is extruded in such a manner that when positioned within the cigarette, its extrusion axis is perpendicular to the longitudinal axis of the cigarette. The fuel element includes a burning segment at one end, a base segment at the opposite end, and an isolation segment between the burning and base segments. The fuel element is circumscribed by glass fibers so as to hold the fuel element in place within the cigarette.Type: GrantFiled: April 21, 1992Date of Patent: February 2, 1993Assignee: R. J. Reynolds Tobacco CompanyInventors: Jack F. Clearman, Billy T. Conner

Patent number: 5159942Abstract: Reconstituted tobacco material is provided by extracting tobacco material using water to provide an insoluble portion and an aqueous extract. The insoluble portion is formed into a sheet-like shape. The aqueous extract is blended with a further tobacco extract which is provided by treating Burley tobacco strip with ammonia and steam. The aqueous tobacco extract and further tobacco extract optionally can be heat treated, contacted with a water soluble phosphate salt, and/or contacted with levulinic acid. The aqueous extract and further tobacco extract are combined with the insoluble portion, resulting in a reconstituted tobacco material. The reconstituted tobacco material is blended with other tobacco materials and employed as cut filler in cigarette manufacture.Type: GrantFiled: June 4, 1991Date of Patent: November 3, 1992Assignee: R. J. Reynolds Tobacco CompanyInventors: Paul A. Brinkley, Thomas W. Brown, Jack G. Flinchum, Jr., Thomas A. Perfetti, James S. Thomasson, Harvey J. Young

Patent number: 5156170Abstract: A cigarette includes a longitudinally segmented combustible fuel element, and a substrate carrying tobacco extract and glycerin positioned physically separate from the fuel element. The fuel element is composed of a carbonaceous material and is extruded in such a manner that when positioned within the cigarette, its extrusion axis is perpendicular to the longitudinal axis of the cigarette. The fuel element includes a burning segment at one end, a base segment at the opposite end, and an isolation segment between the burning and base segments. A metal cartridge is radially spaced from the longitudinal outer periphery of the burning segment of the fuel element. A retaining member grasps the base segment of the fuel element and holds the fuel element securely in place within the cigarette.Type: GrantFiled: June 12, 1991Date of Patent: October 20, 1992Assignee: R. J. Reynolds Tobacco CompanyInventors: Jack F. Clearman, Joseph J. Chiou, Darrell D. Williams, William J. Casey, Thomas L. Gentry, William C. Squires

Patent number: 5139140Abstract: A hinged lid cigarette package can have cigarettes removed therefrom as is common for a hinged lid package or as is common for a soft package. The hinged lid package includes a top panel having a stationary portion and a removable portion. Removal of the removable portion exposed a movable flap which can be opened and closed to allow removal of cigarrettes from the package and closure of the package.Type: GrantFiled: June 19, 1991Date of Patent: August 18, 1992Assignee: R. J. Reynolds Tobacco CompanyInventors: Diane S. Burrows, Larry D. Cobler

Patent number: 5129408Abstract: A combustible smokable filler material includes an agglomerated matrix of an inorganic component (e.g., particles of calcium carbonate) and an organic component (e.g., an alginate). The smokable filler material also includes a binding agent, and an aerosol forming material. Tobacco extracts and/or pieces of tobacco laminae can be incorporated into the smokable filler material, and/or the smokable filler material can be blended with tobacco cut filler. Cigarettes are provided by wrapping the smokable filler material in a paper wrapping material. A typical paper wrapping material has a porosity of less than about 5 CORESTA units.Type: GrantFiled: August 15, 1990Date of Patent: July 14, 1992Assignee: R. J. Reynolds Tobacco CompanyInventors: Stephen W. Jakob, Ernest G. Farrier, James L. Resce

Patent number: 5105838Abstract: A cigarette having a circumference of about 25 mm includes a rod of tobacco cut filler having a circumference of about 12.5 mm which is in turn circumscribed by an air permeable insulating material. The tobacco cut filler has a packing density of less than about 400 mg/cm.sup.3. The insulating material comprises a fibrous material (e.g., glass fibers), and has a radial thickness of greater than about 0.25 mm, and often greater than about 0.5 mm. The insulating material is in turn circumscribed by a paper wrapping material having a low air permeability (e.g., less than about 15 CORESTA units). The cigarette includes a filter element at one end. The cigarette yields low levels of visible sidestream smoke.Type: GrantFiled: October 23, 1990Date of Patent: April 21, 1992Assignee: R.J. Reynolds Tobacco CompanyInventors: Jackie L. White, Thomas A. Perfetti

Patent number: 5105836Abstract: A combustible smokable filler material includes an agglomerated matrix filler having an inorganic component (e.g., particles of calcium carbonate) and a carbonaceous component (e.g., calcined molasses). The smokable filler material includes a binding agent and an aerosol forming material. Tobacco extracts and/or pieces of tobacco laminae can be incorporated into the smokable filler material, and/or the smokable filler material can be blended with tobacco cut filler. Cigarettes are provided by wrapping the smokable filler material in a paper wrapping material. A typical paper wrapping material has a porosity of less than about 5 CORESTA units.Type: GrantFiled: August 15, 1990Date of Patent: April 21, 1992Assignee: R. J. Reynolds Tobacco CompanyInventors: Jeffery S. Gentry, Gary R. Shelar, Richard L. Lehman, James L. Resce, Olivia D. Furin, Stephen W. Jakob, William C. Squires

Patent number: 5101839Abstract: A smokable filler material includes an aerosol forming material (e.g., propylene glycol and glycerin) and a binding agent (e.g., ammonium alginate). Tobacco extracts and/or pieces of tobacco laminae can be incorporated into the smokable filler material, and/or the smokable filler material can be blended with tobacco cut filler. The amount of aerosol forming material within the smokable filler material typically is at least about 20 percent, based on the weight of that smokable filler material. Cigarettes are provided by wrapping the smokable filler material in a paper wrapping material. A typical paper wrapping material has a porosity of less than about 5 CORESTA units. Cigarettes cn include two layers of circumscribing paper wrapping materials. Cigarettes also can include filter elements.Type: GrantFiled: August 15, 1990Date of Patent: April 7, 1992Assignee: R. J. Reynolds Tobacco CompanyInventors: Stephen W. Jakob, Michael D. Shannon, Olivia D. Furin, Paul F. Bernasek, Richard L. Blakley, Johnny L. Brooks, Karen M. Womble, Gary R. Shelar, James L. Resce

Patent number: 4889143Abstract: Rods are manufactured by shredding strips of sheet-like reconstituted tobacco material into a plurality of strands of about 1/32 inch width. The strands are gathered into a rod-like shape and circumscribed by paper wrap in order to provide a continuous rod. The continuous rod is severed at regular intervals to provide a plurality of rods of the desired length. The resulting rods have a plurality of substantially longitudinally extending strands provided from shredded sheet-like material. The rods are useful as cigarette rods or in the manufacture of cigarette filter elements.Type: GrantFiled: May 14, 1986Date of Patent: December 26, 1989Assignee: R. J. Reynolds Tobacco CompanyInventors: James W. Pryor, Mark L. Raker, Andrew J. Sensabaugh, Jr., Henry A. Hauser

Patent number: 4474860Abstract: Bimodal latexes having two separate and distinct particle size distributions have high solids content, good high shear rheology and good low shear viscosity. These bimodal latexes, e.g., styrene/butadiene/acrylic acid/itaconic acid latexes are employed in coating paper in conjunction with a mineral filler using a coating device such as a blade coater to yield high quality coatings which can be easily applied.Type: GrantFiled: May 16, 1983Date of Patent: October 2, 1984Assignee: The Dow Chemical CompanyInventors: Ronald L. Van Gilder, Do I. Lee
