Patent number: 5240015Abstract: This invention is devised to be a free standing wetted impact barrier for dispensing onto a cigarette. Only when applied on the top mouthpiece of cigarette filter types does it become a part of the filter. More particularly, this invention relates to a wetted impact barrier kit which includes a free standing wetted barrier placed in a container with a dispenser and an instruction sheet on how to use the kit. The wetted impact barrier is dispensed on the top end surface of cigarette filter type mouthpiece, to reduce tar and nicotine of cigarettes (total particular matter), when smoked. This invention is designed only to dispense the wetted impact barrier on the top end surface of a mouthpiece of a cigarette filter The wetted impact barrier helps to eliminate or remove the primary tars and nicotine and certain other volatiles from cigarette smoke.Type: GrantFiled: February 14, 1991Date of Patent: August 31, 1993Inventors: William E.

Patent number: 5191905Abstract: A filter cigarette is provided which has a cigarette section formed by wrapping shredded tobacco in a cigarette paper sheet and a filter section having a filter chip integrally joined to the cigarette section. The filter chip is formed by combining in a bundle at least one absorptive synthetic fiber selected from the group consisting of (1) graft polymer fibers produced from irradiated polypropylene reacted with vapor phase styrene and containing adsorptive functional groups, (2) activated carbon fibers, (3) charged electret fibers, and (4) magnetic plastic fibers and then chopping the combined fiber bundle to a predetermined length. Since the filter section does not contain adsorptive grains or particles (i.e., activated charcoal grains or particles), the integrated cigarette manufacturing plant for such filter cigarettes does not required a process or equipment for preventing the scattering of the adsorptive grains or the collection of such grains when they do escape.Type: GrantFiled: March 12, 1991Date of Patent: March 9, 1993Assignee: Costarica Sogo Kaihatsu Co., Ltd.Inventor: Kenkichi Tsukamoto

Method of fabricating an all-tobacco cigarette controlling tar delivery and an all-tobacco cigarette
Patent number: 5007439Abstract: This invention relates to a method of controlling the "tar" delivery of cigarette smoke and more particularly to the method of controlling "tar" delivery of the non-filter cigarette while maintaining resistance to draw and other parameters of the cigarette at acceptable levels.Type: GrantFiled: November 17, 1987Date of Patent: April 16, 1991Assignee: The American Tobacco CompanyInventor: Richard D. Chumney, Jr. -
Patent number: 4993434Abstract: Methods and apparatus for applying liquid strands containing additives to cigarette rods. Liquid is extruded to form one or more strands that are applied to loose tobacco filler in the chimney section of a conventional cigarette maker. The liquid has a viscosity that prevents it from soaking through the tobacco and contacting the cigarette maker or the cigarette wrapper. Additives to the liquid strands include flavorants, burn inhibitors, and burn accelerators.Type: GrantFiled: June 29, 1989Date of Patent: February 19, 1991Assignee: Philip Morris IncorporatedInventors: Lewis A. Haws, Jose G. Nepomuceno

Patent number: 4993436Abstract: A dispenser comprising a container and a mouthpiece is adapted to deliver a volatilizable liquid orally to the user. A volatilizing chamber is defined between the liquid reservoir in the container and the drawing passage in the mouthpiece through which the user inhales. A permeable fluid barrier separates the liquid in the reservoir from the open pore material which fills the volatilizing chamber and limits the amount of liquid which can be aspirated through the open pore material to the user. A vent passage in parallel with the fluid barrier when uncovered and open allows air to be drawn through the open pore material to volatilize any liquid retained thereon. When covered and closed, the vent passage allows liquid to be aspirated from the reservoir through the permeable fluid barrier, the volatilizing chamber, and the mouth piece and into the user's mouth.Type: GrantFiled: December 21, 1989Date of Patent: February 19, 1991Inventor: Walter L. Bloom, Jr.

Patent number: 4991605Abstract: A container for containing an additive material for modifying the characteristics of a smoking article. The container contains at least two components that are movable between a first position and a second position with respect to each other. In the first position the additive material is hermetically sealed inside the container during storage of the smoking article prior to use. The container is activated by moving the components of the container to the second position to provide air flow pathways through the container so that the additive material can modify the smoking article accordingly. The components may have perforations that are covered by cooperating overlapping portions of the components of the container in the first position and uncovered in the second position. Alternately, the container may include a sealed capsule containing the additive that is punctured by moving the components during activation.Type: GrantFiled: April 24, 1989Date of Patent: February 12, 1991Assignee: Philip Morris IncorporatedInventor: Gus D. Keritsis

Patent number: 4991596Abstract: A smoking article includes a short, combustible, carbonaceous fuel element in a heat exchange relationship with a substrate carrying glycerin, tobacco extract, and a portion of an essential oil gland bearing plant. For example, fragments of cinnamon bark, lovage root, chamomile flowers or cardamon physically separate from the fuel element provide for a controlled release of a flavor profile during use of the smoking article. Heat provided by the burning fuel element acts to release essential oils from the glands to provide a complex flavor and aroma profile. The smoking article is capable of providing the user with many of the pleasures of smoking by heating but not necessarily burning tobacco.Type: GrantFiled: July 11, 1989Date of Patent: February 12, 1991Assignee: R. J. Reynolds Tobacco CompanyInventors: Brian M. Lawrence, Milly M. L. Wong, Thomas A. Perfetti, Thomas L. Gentry, Alvaro Gonzalez-Parra, Jerry W. Lawson, Gary R. Shelar, Gary W. Worrell

Patent number: 4981522Abstract: A flavor source to be used as a thermally releasable flavorant for smoking articles that do not combust tobacco. The material includes tobacco particles, an aerosol precursor that forms an aerosol upon exposure to heat, and a filler material that absorbs and radiates heat to minimize the likelihood that the flavor material will ignite. The material is mixed in an extruder, extruded through a die, and cut into pellets having a substantially uniform shape. The pellets are loaded into a chamber for inclusion in a smoking article as a flavor generator.Type: GrantFiled: July 22, 1988Date of Patent: January 1, 1991Assignee: Philip Morris IncorporatedInventors: Walter A. Nichols, Harry V. Lanzillotti, Richard A. Thesing, Alex S. Gergely, Constance H. Morgan, Bruce E. Waymack, D. Bruce Losee, Jr., John R. Hearn, Johnny L. Miller

Patent number: 4971078Abstract: A filter for a smoking article includes: a flavorant; a hollow fiber made of a thermoplastic, the flavorant dispersed in the thermoplastic; and a filter plug in which the fiber is embedded. Additionally, the hollow fiber may be sheathed with a layer of cellulose acetate.Type: GrantFiled: August 15, 1989Date of Patent: November 20, 1990Assignee: Hoechst Celanese CorporationInventors: Lance J. Deutsch, Cheryl E. Johnson

Patent number: 4967772Abstract: A tobacco smoking article including smoking tobacco held in a container and an alcohol supported by the container. The alcohol has two or more carbon atoms and is capable when the vapor thereof is inhaled by the smoker of inhibiting the selective localization of nitrosamines and metabolites thereof in the smoker's tissues, such as those of the bronchial epithelium. The alcohol is associated with the smoking tobacco such that, when the tobacco is smoked, the vapors of the alcohol are inhaled in the tobacco smoke stream. The alcohol is present in an amount sufficient to inhibit the selective localization but not to produce any toxic side effects in the smoker.Type: GrantFiled: August 13, 1987Date of Patent: November 6, 1990Assignee: C.A. Blockers, Inc.Inventors: William J. Waddell, Carolyn Marlowe, L. Douglas Keeney
