| 20080216848 | Smoking article filter with annular restrictor and downstream ventilation - A smoking article includes a tobacco rod adapted to produce mainstream smoke, and a filter having an upstream end portion and a downstream end portion. The filter includes a ventilated cavity and a flow restrictor segment having an impermeable insert at least partially surrounded by a tubular segment of an air transmissive material upstream of the cavity. In an embodiment, the tubular segment at least partially defines the cavity. | 09-11-2008 |
| 20080283067 | VARIOUS EMBODIMENTS FOR PRODUCING A TOBACCO ROD WITH A HOLLOW CYLINDRICAL TUBE EXTENDING THERETHROUGH - A method for making cigarettes comprising feeding tubing piece-by-piece to a vertical duct by opening and closing-timing gate operated by cam, accelerating tubing down to the vertical duct, with the help of vertical accelerator belts until the tubing becomes captured into the hopper holder, picking the tubing with an articulate tubing holder located on a transferring drum, lowering to the garniture, and releasing the tubing under the registration lagged-belt. | 11-20-2008 |
| 20090014020 | Smoking article with valve - A smoking article having a cylinder of smoking material, a hollow tube within the cylinder of smoking material, and a filter attached to the cylinder of smoking material. The filter includes an upstream segment containing an aerosol former, a downstream segment containing a sorbent material, and a valve positioned between the upstream segment and the downstream segment. The valve has a first position in which the valve is closed and a second position in which the valve is open and allows the passage of smoke through the filter. | 01-15-2009 |
| 20090165809 | Method and apparatus for dispensing a metered amount of liquid to a porous plug - A dispenser for dispensing a metered amount of liquid into a porous plug includes a casing which has an inlet passage adapted to receive a manually insertable porous plug. A reservoir disposed in the cavity contains the liquid. The reservoir has an outlet which is communicable with the inlet passage. A discharge mechanism disposed in the casing is actuable in response to the insertion of a porous plug into the inlet passage for producing a pressurized air flow which bears against a piston in the reservoir for discharging a metered amount of the liquid from the reservoir into the porous plug. The plug could constitute a filter attached to a tobacco column. | 07-02-2009 |

| 20080216850 | Restrictor attachment for unfiltered smoking article - A smoking article having an unfiltered tobacco rod, a connector attach to the tobacco rod and a mouthpiece. The connector includes a cavity, a transverse partition within the cavity, the transverse partition having at least one orifice, and a plurality of ventilation passages positioned around an outer periphery of the connector. Each of the plurality of ventilation passages includes an inlet and an outlet to provide ventilation to the cavity. The mouthpiece is adapted to attach to a downstream end of the connector. | 09-11-2008 |
| 20080216853 | Smoking article with open ended filter and restrictor - A smoking article includes a tobacco rod adapted to produce mainstream smoke, and a filter having an upstream end and a downstream end, wherein the filter is arranged to receive mainstream smoke at the upstream end. The filter includes a tubular segment open at the downstream end thereof and a flow restrictor contained within the tubular segment. The filter is attached to the tobacco rod with tipping paper and includes an air-admissible ventilating zone at a location between the upstream end and the downstream end of the filter. | 09-11-2008 |
| 20090165935 | FILTER TUBE MAKING - A hollow filter tube is produced with a longitudinal seam and a fixed diameter. In the formation of the hollow tube glue is applied along a longitudinal side edge portion of an endless strip, and the strip is then formed into a tubular shape with an unglued longitudinal edge portion tucked directly under and against the glued side edge portion. The hollow tube is then heated to drive moisture from the glue and size and shape the hollow tube. Ultimately the formed hollow tube is cut into specific lengths. | 07-02-2009 |
