Patent number: 6748955Abstract: 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: February 15, 2002Date of Patent: June 15, 2004Assignee: Rothmans, Benson & Hedges Inc.Inventors: Stanislav M.

Patent number: 6568400Abstract: A dual function water pipe includes a water-holding container and serves as a loose leaf tobacco pipe and as a cigarette smoking device. A bowl surmounts the container and a downspout of the bowl extends into the container an extent sufficient to submerge the free end of the downspout. A hollow adapter having a radial bore that holds the unlit end of a cigarette surmounts the bowl. A smoker applies suction to a smoke tube that draws smoke from the cigarette and the structure of the device causes the smoke to follow a path of travel that constrains the smoke to pass through the water before entering the smoke tube, removing some toxins from the smoke. The smoke tube is positioned one hundred eighty degrees from the cigarette and has a telescopically-extended configuration that positions a flame source a safe distance from a user's face.Type: GrantFiled: February 15, 2002Date of Patent: May 27, 2003Inventors: Steve R. Tinsky, Soji Fujita

Patent number: 6311694Abstract: A smoking article comprises a smoking accessory and a cigarette. The smoking accessory includes a holder and a substantially air-impermeable sleeve which is coupled to a distal portion of the holder and is coaxial therewith. The cigarette is received in the smoking accessory such that a distal end of the cigarette is located substantially flush with a distal end of the sleeve. The cigarette includes a column of tobacco which is shorter than that used in conventional cigarettes, e.g., 20 mm in length or less. An air gap separates an outer surface of the cigarette from the sleeve, and plural openings are formed in the sleeve to supply air to the cigarette. In use, the sleeve restricts the flow of air to the cigarette, thereby slowing combustion and reducing sidestream smoke between puffs.Type: GrantFiled: July 2, 1999Date of Patent: November 6, 2001Assignee: Philip Morris IncorporatedInventors: Walter A. Nichols, John R. Hearn, F. Murphy Sprinkel, Jr., Jay A. Fournier, Jerry F. Whidby

Patent number: 6148826Abstract: A device for smoking combustible materials includes a tubular body member constructed entirely of heat-resistant glass material. The device has an internal bore with an integrally formed venturi that separates the bore into a smoke chamber and a loading chamber. A method of forming the device includes providing a tubular body member constructed entirely from a heat-resistant glass material; forming a constricted passage in a bore of the tubular body member by applying heat to a predetermined location on the tubular body member until the glass material expands into the bore at the predetermined location; and smoothing the outer surface of the tubular body member at the predetermined location.Type: GrantFiled: March 16, 1998Date of Patent: November 21, 2000Inventors: Ronald Boyd Lancaster, Lewis James Danforth

Patent number: 6073633Abstract: The safety smoking pipe includes first and second parts telescopically receivable one within the other and rotatable relative to one another. The first part includes an elongated tube having a screen adjacent one end. The second part includes an elongated tube terminating at its proximal end in a pipe tip and having an axially extending cleaning member terminating in a cleaning head. A packing element is disposed for sliding movement along the cleaning rod. The tobacco materials are charged into the first tube, the tobacco materials adjacent the screen end are lit, and the ash being formed on the interior of the screen extinguishing the tobacco materials after a few puffs. By rotating the parts relative to one another, the cleaning head may clean the ash from the end of the pipe. By shaking the pipe screen end down, the weight repacks the tobacco material in the tube whereby the smoking materials can once again be ignited.Type: GrantFiled: December 18, 1998Date of Patent: June 13, 2000Inventor: Arthur L. Herman

Patent number: 6006757Abstract: A cigarette holder completely encloses the lit end of a cigarette providing purification for both sidestream smoke and mainstream smoke. It has two concentric tubes with the lit cigarette placed in the inner tube and purifying agent placed in the volume between the inner tube and the outer tube. A chimney effect is produced wherein air flows through an air port past the lit cigarette to keep it burning. The sidestream smoke passes through the purifying agent and is discharged into the environment. The filter tip of the lit cigarette extends through a mouthpiece and the smoker exhales smoke through openings in the same mouthpiece. The mainstream smoke passes through the same purifying agent, in a direction opposite to the flow of the sidestream smoke, and is then discharged into the environment.Type: GrantFiled: May 14, 1998Date of Patent: December 28, 1999Inventor: Edward Lichtenberg
-
Patent number: 4788988Abstract: A smoking device is disclosed whereby smoke and other gases of combustion can be diluted with air to a pre-selected mixture before being inhaled by a smoker. This is achieved by the use of a carbureting tube which can introduce a metered amount of air into a smoke chamber and thereby dilute the smoke to any desired concentration. The smoke is drawn into the smoke dilution chamber by a piston moving towards the outlet end of the chamber, and then pumped out of the smoke dilution chamber by reversing the motion of the piston. A water chamber may also be included to permit the smoke and other gases to be cooled prior to entering the smoke dilution chamber.Type: GrantFiled: January 30, 1987Date of Patent: December 6, 1988Inventor: Matthew G. Titus

Patent number: 4687008Abstract: A cigarette is provided having a variable length. A filter or mouthpiece slides within a sleeve attached to the cigarette, or a sleeve attached to the filter or mouthpiece slides over the cigarette. A single band is adhered to one element and a pair of bands is adhered to the other element. The single band is captive between the pair of bands so that the cigarette can be lengthened or shortened within the range allowed by the pair of bands, but the filter or mouthpiece cannot be removed from the cigarette. The variable length mechanism can be made to additionally provide variable dilution or variable flavorant.Type: GrantFiled: April 17, 1986Date of Patent: August 18, 1987Assignee: Philip Morris IncorporatedInventors: Willie G. Houck, Jr., Francis M. Sprinkel, Jr., Reginald W. Newsome, David B. Spruill, Walter A. Nichols
