Publication number: 20040173230Abstract: A device for minimizing cigarette sidestream smoke and reducing free-burn rate of a burning cigarette is disclosed. The device comprises a non-combustible tubular element encasing an effective length of a tobacco charge of a cigarette located in the tubular element. The tubular element minimizes sidestream smoke emission from a burning tobacco charge and reduces free-burn rate of such burning tobacco charge to increase the number of puffs from the burning tobacco charge.Type: ApplicationFiled: March 11, 2004Publication date: September 9, 2004Applicant: Rothmans, Benson & Hedges Inc.Inventors: Stanislav M.

Publication number: 20040173231Abstract: A cigarette sidestream smoke treatment material made from a sheet of non-combustible active components provides a porous structure capable of treating sidestream smoke. The treatment material, as used in combination with a cigarette, provides a low sidestream smoke emitting cigarette unit. The material has a porosity which encourages a conventional free-burn rate of a conventional cigarette. The material may comprise a sorbent capable of sorbing components of the sidestream smoke, and an oxygen storage component which releases oxygen at free-burn rate temperatures to ensure that conventional free-burn rate is maintained and to enhance the oxidation treatment of the adsorbed non-aqueous components. Preferably, an oxidation catalyst is included in the material and most desirably the oxygen storage component may also function as the oxidation catalyst. Particularly preferred materials which perform the dual function are oxides of cerium.Type: ApplicationFiled: March 22, 2004Publication date: September 9, 2004Applicant: Rothmans, Benson & Hedges Inc.Inventors: Larry Bowen, Stanislav M.

Publication number: 20040007242Abstract: The invention relates to a low ignition propensity cigarette having a self-extinguishing cigarette wrapper which is capable of self-extinguishing the cigarette. The cigarette wrapper comprises an oxygen storage and donor metal oxide to support and maintain free-burn of the self-extinguishing cigarette while retaining the low ignition propensity property of the self-extinguishing cigarette wrapper. The invention further relates to a low sidestream smoke cigarette having low ignition propensity properties. The wrapper has a composition which reduces sidestream smoke from a burning cigarette and comprises in combination, an oxygen storage and donor metal oxide catalyst and an essentially non-combustible finely divided porous particulate adjunct for the catalyst. The sidestream smoke reducing composition reduces porosity of the wrapper to render the cigarette as self-extinguishable.Type: ApplicationFiled: April 22, 2003Publication date: January 15, 2004Applicant: Rothmans, Benson & Hedges Inc.Inventors: Warren Finlay, Stanislav M.

Publication number: 20030114298Abstract: A process that provides a catalytic rare earth oxide-coated microporous free-flowing bulk particulate wherein the amount of metal oxide coated thereon is high, without jeopardizing the effectiveness of the material. The rare earth metal oxide coated on the outer surface may be in the range of 20 to 70% by weight based on the total equivalent rare earth metal oxide and microporous particulate material content. In particular, a zeolite free-flowing bulk particulate having high loadings of rare earth metal oxide tends to be quite stable. For instance, when the rare earth metal oxide-coated zeolite free-flowing bulk particulate has been heat treated at temperatures less than about 200° C. and then slurried in water, typically, less than 30% by weight of the rare earth metal oxide (based on the total equivalent rare earth metal oxide content) is found to leach into water. This material has been found to have minimal leachability when heat treated above about 400° C.Type: ApplicationFiled: September 13, 2002Publication date: June 19, 2003Applicant: Rothmans, Benson & Hedges Inc.Inventors: James L.

Publication number: 20030069132Abstract: A zirconium metal oxide fibre comprises zirconium oxide and a metal oxide. The fibre is made by adding a metal oxide in a suitable form to a colloidal dispersion of an amorphous zirconium polymer. The mixed colloidal dispersion is subsequently made into a fibre. The fibre may be used as a substitute for glass fibre in the manufacture of paper and paper-like materials. The fibre's thickness is substantially uniform and has a length usually in excess of one micron.Type: ApplicationFiled: September 13, 2002Publication date: April 10, 2003Applicant: Rothmans, Benson & Hedges Inc.Inventor: James L.

Patent number: 6223895Abstract: In accordance with the present invention there is provided a novel cigarette packaging system for “making your own” smokeable cigarettes. The kit is easily opened and allows a smoker to assemble a smokeable cigarette quickly without requiring great effort. The kit is inexpensive, convenient to use and also convenient to carry and store as its compact size is such that it fits in a person's hand, a shirt or coat pocket as well as in a ladies bag or purse. The kit is also advantageous because it is less expensive than tailor made cigarettes, yet is not that much wider than a standard, typical package of cigarettes. The construction of the kit, is such that it keeps the unsmokeable tobacco elements in a separate compartment which serves to help maintain the freshness of the tobacco.Type: GrantFiled: September 24, 1999Date of Patent: May 1, 2001Assignee: Rothmans, Benson & Hedges Inc.Inventors: Larry Bowen, Norman Cohen

Patent number: 5938018Abstract: A re-usable aroma releasant is provided on a package of tobacco product such as cigarettes, pipe tobacco, fine cut tobacco and the like. The aroma releasant is activated to release aroma every time the package is opened. The packages comprises a tobacco product containment portion and a tobacco product containment closure portion. The closure portion is removed from the containment portion to gain access to the tobacco product. The aroma releasant may have a peel seal connecting the containment portion and the closure portion. The peel seal seals the aroma in the substrate reservoir provided on the package. The peel seal is peeled from the substrate reservoir to permit opening of the package and simultaneously releasing aroma from the reservoir. The peel seal reseals the reservoir on closure of the package. A re-usable aroma releasant is provided where every time the smoker opens the package, fresh aroma is released.Type: GrantFiled: April 15, 1998Date of Patent: August 17, 1999Assignee: Rothmans, Benson & Hedges Inc.Inventors: Benedict Keaveney, David R.E.

Device for controlling free-burn rate of and reducing sidestream smoke from a cigarette and the like
Patent number: 5915388Abstract: A device and process for using same is described for controlling free burn rate of a lit cigarette. The device is mountable on a cigarette and is adapted to permit insertion and movement of the cigarette into the device. The device includes a unit which controls rate of air diffusion to reduce supply of oxygen for supporting tobacco combustion by the lit cigarette coal. The structure for controlling rate of air diffusion is non-combustible at combustion temperature of a lit cigarette coal. By use of this device, the number of puffs per cigarette is greatly increased and, depending upon the selected design of the device for controlling free burn rate can reduce sidestream smoke emitted by a lit idle cigarette.Type: GrantFiled: September 3, 1997Date of Patent: June 29, 1999Assignee: Rothmans, Benson & Hedges Inc.Inventors: Larry Bowen, Stanislav M.
