Publication number: 20150150304Abstract: Tobacco smoking mixtures capable of producing tobacco smoke are provided which reduce the cytotoxicity and/or mutagenicity of the tobacco smoke. The tobacco smoking mixtures include tobacco cut filler and glycerin in an amount effective to reduce cytotoxicity and/or mutagenicity of smoke produced by the tobacco smoking mixture. The tobacco smoking mixtures enable a further reduction in cytotoxicity and/or mutagenicity when glycerin is combined with palladium or salts of calcium and/or magnesium.Type: ApplicationFiled: December 8, 2014Publication date: June 4, 2015Inventors: San Li, Raquel Olegario, Joseph L. Banyasz, Kenneth H. Shafer

Patent number: 8424540Abstract: A smoking article filter includes a valved flow restrictor and a cavity downstream of the flow restrictor. The flow restrictor includes an orifice or flow channel for directing smoke into the cavity. The filter is attached to the tobacco rod with tipping paper and includes an air-admissible ventilating zone at a location downstream of the restrictor. The valved restrictor can be used to isolate a sorbent bearing component of the filter from a flavor bearing component.Type: GrantFiled: October 9, 2009Date of Patent: April 23, 2013Assignee: Philip Morris USA Inc.Inventors: Raquel Olegario, San Li, Roland W.

Publication number: 20110083687Abstract: A smoking article having a tobacco rod adapted to produce mainstream smoke, and a filter having an upstream end portion and a downstream end portion, and wherein the filter is arranged to receive mainstream smoke at the upstream end portion. The filter includes a first filter segment of low particulate efficiency at the upstream end portion; a channeled flow segment adjacent to the first filter segment, the channeled flow segment including a flow channel establishing a substantial portion of a predetermined resistance to draw of the smoking article; a mouthpiece filter segment of low particulate efficiency at the downstream end portion; and a tubular body segment at least partially defining a portion of a cavity between the mouthpiece filter and the channeled flow segment. Tipping paper attaches the filter with the tobacco rod and includes an air-admissible ventilation zone at a location along the tubular body segment.Type: ApplicationFiled: October 9, 2009Publication date: April 14, 2011Applicant: Philip Morris USA Inc.Inventors: Raquel Olegario, San Li, Mike Braunshteyn, Roland W.
