Patent number: 7677256Abstract: Smokable rods of cigarettes are manufactured using wrapping materials that incorporate at least one fibrous material (e.g., flax fibers, hardwood pulp fibers and/or softwood pulp fibers) at least one filler material (e.g., calcium carbonate in particulate form). The wrapping materials possess multi-layer coatings. The wrapping materials possess coatings in the form of series of spaced apart bands, each band possessing a series of layers. At least one of the coating layers can have a filler material dispersed or suspended within a film-forming material of that layer.Type: GrantFiled: September 13, 2005Date of Patent: March 16, 2010Assignee: R.J.

Publication number: 20090065012Abstract: Cigarettes are manufactured using modified automated cigarette making apparatus. Those cigarettes possess smokable rods having paper wrapping materials having additive materials applied thereto as patterns. The additive material can be applied as a coating formulation in an off-line manner to a continuous paper sheet web that is later used for cigarette manufacture. The additive material can be applied as a coating formulation in an on-line manner to continuous paper web moving through an operating cigarette making machine. The coating formulation is applied to the paper web using roll applicator techniques, ink jet printing techniques or electrostatic precipitation techniques. Liquid coating formulation are curable, and are virtually absent of solvent or liquid carrier. Radiation, such as ultraviolet or electron beam radiation, is used to solidify and fix polymerizable liquid components of the coating formulation that have been applied to the paper web.Type: ApplicationFiled: September 4, 2008Publication date: March 12, 2009Inventors: Pankaj Patel, Charles Ray Ashcraft, John Joseph Tomel, JR., Gregory Alan Holmes, Vernon Brent Barnes, Lloyd Harmon Hancock, James Herbert Ellis, JR., James Ray Hutchens, Gregory Scott Pierce, Don Hayes White

The wrapping materials possess multi-layer coatings. The wrapping materials possess coatings in the form of series of spaced apart bands, each band possessing a series of layers. At least one of the coating layers can have a filler material dispersed or suspended within a film-forming material of that layer. For a representative wrapping material, a pattern of applied to the wire side major surface of the wrapping material substrate as a plurality of layers, and at least one of the layers includes ethylcellulose and calcium carbonate. For that layer, the calcium carbonate is present in an amount greater than the ethylcellulose, on a weight basis.Type: GrantFiled: October 15, 2003Date of Patent: July 3, 2007Assignee: R.J.

Patent number: 6726006Abstract: A flask-shaped package or container for packaging smoking articles, such as cigarettes, has a generally parallelepiped shape with slightly curved front and back body panels. The container comprises a body and a lid integrally molded in one-piece of a plastic material with an open bottom having an internal peripheral shoulder and a base made of a separate plastic/metal foil laminate that is bonded to the shoulder by induction heating a heat-activated adhesive covering the metal foil of the base. The body has a central internal front-to-back stiffening rib and an access opening in its top and front panels with a surrounding ledge to which is adhesively bonded a removable foil closure. After the access opening is closed with the foil closure, cigarettes are inserted into the container body through the open bottom thereof.Type: GrantFiled: June 26, 2001Date of Patent: April 27, 2004Inventors: Douglas Amon Funderburk, Charles Ray Ashcraft, Walter Bohdan, Ellen Strickland Gossett, Nancy Harmon Hawley, Jane Cottrell Henson, William Edward Hazlett, Daniel Klaus Self

Patent number: 5762860Abstract: A method of and an apparatus for cooling or quenching a tube extruded from a water soluble polymer includes a plurality of cooling rings with bores through which the extruded tube passes. A gaseous cooling medium, such as compressed air, is supplied to each cooling ring and is directed immediately downstream of the bore thereof to impinge upon and cool the tubing passing therethrough. The cooling medium is supplied annularly so as to maintain the just-extruded tubing concentric and keep it centered in the bore.Type: GrantFiled: March 21, 1996Date of Patent: June 9, 1998Assignee: R.

Patent number: 5709227Abstract: A degradable smoking article comprises a tobacco rod and a filter component made of a gathered web of moisture disintegrative sheet material wrapped with a moisture disintegrative plug wrap bonded along a longitudinal seam with a water soluble adhesive. A moisture disintegrative tipping paper coated on one side with a water soluble adhesive secures the tobacco, rod and filter component together. The combination of moisture and other natural elements such as sunlight, mechanical abrasion, etc., dissociates the components of the smoking article over a relatively short period of time. Other embodiments of the filter component include a hollow degradable tube and a monolithic extruded starch filter rod.Type: GrantFiled: December 5, 1995Date of Patent: January 20, 1998Assignee: R. J. Reynolds Tobacco CompanyInventors: Barbara Walker Arzonico, Michael Francis Dube, Glenn Edward Creamer, Robert Leslie Oglesby, Charles Ray Ashcraft, Robin Kent Wilson
