Patent application number | Description | Published |
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 |
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 |
20080302376 | Smoking article with controlled flavor release - Provided are smoking articles with a controlled flavor release product. The controlled flavor release product includes a first time-release flavorant and a second time-release flavorant. The controlled flavor release product is a film or a lip balm type formulation that is applied to the downstream end of a smoking article. | 12-11-2008 |
20090277465 | FLAVOR CAPSULE FOR ENHANCED FLAVOR DELIVERY IN CIGARETTES - Improved delivery of additive materials to cigarettes is provided through the use of one or more capsules containing additive materials, such as flavor components, in the filter section of a cigarette. The sealed capsule or capsules are subjected to an external force, such as squeezing, by a smoker prior to or during smoking of the cigarette in order to release at least a portion of the additive material from the one or more capsules and expose the additive material to mainstream smoke passing through the filter. The sealed capsules provide a barrier between the additive materials and other cigarettes components, such as sorbents or filter materials, in order to reduce additive material migration into the other cigarette components prior to desired use. | 11-12-2009 |
20110083687 | CIGARETTE FILTER TO REDUCE SMOKE DELIVERIES IN LATER PUFFS - 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. | 04-14-2011 |
20110100388 | SMOKING ARTICLE WITH A RESTRICTOR - A smoking article filter includes a 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. | 05-05-2011 |
20110155154 | Smoking Article with Tobacco Beads - A component of a smoking article having tobacco beads. The tobacco beads can be located in a filter and/or a tobacco rod. The filter can be a multi-component filter, wherein an sorbent (preferably upstream) removes at least one constituent from mainstream tobacco smoke passing through the filter and downstream tobacco beads compensates for taste lost to the sorbent. The tobacco beads optionally include flavorants in addition to tobacco particulates. The tobacco beads can be located within a cavity in the filter or within the tow. This component can comprise additional flavors, which are released into the mainstream smoke under ambient conditions. The tobacco beads optionally include binders such as microcrystalline cellulose or other cellulosic material, which can be formed into a paste with tobacco powder and optionally with additional flavors. The paste can be extruded and spheronized to form the tobacco beads. | 06-30-2011 |
20150027454 | ELECTRONIC SMOKING ARTICLE - An electronic smoking article includes a liquid aerosol formulation, a heater operable to at least partially volatilize the liquid aerosol formulation and form an aerosol and a tubular filter segment downstream of the heater. The tubular filter segment is operable to selectively filter aerosol particles and vapors from the aerosol. | 01-29-2015 |
