Patent number: 7624739Abstract: 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: GrantFiled: November 9, 2005Date of Patent: December 1, 2009Assignee: Rothmans, Benson & Hedges Inc.Inventors: Stanislav M. Snaidr, Larry Bowen, Warren A. Brackmann

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.

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

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.

Patent number: 5752528Abstract: A cigarette extinguishing and storage device is of tubular shape and provided by telescoping elements which define an enclosure in which a lit cigarette is received to extinguish the same and in which the extinguished cigarette is stored until the smoker wishes to relight the same. Charcoal or other suitable deodorant means is provided at the internal surface of the enclosure to absorb condensates from tobacco smoke. The device preferably is made of one or more plies of paper, so as to be disposable.Type: GrantFiled: February 23, 1996Date of Patent: May 19, 1998Assignee: Rothmans, Benson & Hedges Inc.Inventors: George E. Ayres, Gary D. Black, Larry Bowen, Warren A. Brackmann, Benedict Keaveney, John D. Kilpatrick

Patent number: 5709228Abstract: Significant decreases in sidestream smoke production, approximately 30 to 70%, are obtained when compared to a tobacco filler rod wrapped in a conventional cigarette paper by double-wrapping the filler rod, first with a relatively non-porous paper having a Coresta porosity of about 1 to about 10% and then with a conventional cigarette paper.Type: GrantFiled: June 7, 1995Date of Patent: January 20, 1998Assignee: Rothmans, Benson & Hedges, Inc.Inventors: Norman Cohen, Larry Bowen

Patent number: 5699812Abstract: A novel reconstituted tobacco sheet material is provided which is useful in providing a novel smoking product which has a smoking quality closely approximating that of cigarettes having conventional paper wrappers. The reconstituted tobacco sheet is prepared by a paper-making process in which the water-soluble material extracted in the paper-making process is not added back to the sheet, or if added back, to an extent of no more than 20 wt % of the reconstituted tobacco sheet. In the novel smoking product, a tobacco filler rod is enclosed within an outer wrapper, which usually comprises an inner binder layer and an outer wrapper layer, one or both formed of reconstituted tobacco sheet material. When the tobacco filler rod is double-wrapped, the novel smoking product also exhibits a significant reduction in sidestream smoking production in comparison to a conventionally-wrapped cigarette.Type: GrantFiled: June 2, 1995Date of Patent: December 23, 1997Assignee: Rothmans, Benson & Hedges Inc.Inventors: Larry Bowen, George Edward Ayres, Gary Black, Jacques Daoust
