| 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 |
| 20080286408 | Encapsulation of a hydrophilic substance in small capsules - Provided is a method of encapsulating a hydrophilic substance with wax. Also provided, is a method of encapsulating honey with an edible wax to create honey capsules. The method includes ejecting a droplet of the hydrophilic substance into a stream of molten wax and allowing the droplet to pass through the molten wax to enter a container of water. The wax capsule forms an oral product that may be placed in the mouth or used in conjunction with other edible or oral products. | 11-20-2008 |
| 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 |
| 20090004337 | Wax capsules containing hydrophilic cores - Provided is a method for cooling wax after coextrusion to create wax capsules. The method includes immersing a concentric nozzle of a coextruder in a container of heated alcohol. The container of heated alcohol sits in a water-ice bath to create a temperature gradient. A core material having a wax coating is extruded through a concentric nozzle to form a capsule. The capsule enters the container of hot alcohol where the wax coating is solidified. In an embodiment, the method is a continuous method including a capsule and solvent transfer system. | 01-01-2009 |
| 20090159091 | Activated carbon from microcrystalline cellulose - A method of forming activated carbon from microcrystalline cellulose comprises converting the microcrystalline cellulose powder into microcrystalline cellulose beads using extrusion and spheronization, carbonizing microcrystalline cellulose to form carbonized microcrystalline cellulose and activating the carbonized microcrystalline cellulose to form activated carbon. The final size of the activated carbon beads, which preferably are of practically spherical shape, can be controlled through the process of making microcrystalline cellulose beads. | 06-25-2009 |
| 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 |
| 20100152040 | Carbon Beads With Multimodal Pore Size Distribution - A method of producing a multi-modal pore distribution activated carbon is provided herein by preparing a solution comprising a polymer precursor, mixing an additional material with the polymer precursor in the solution, cross-linking the polymer precursor with the additional material mixed therein, carbonizing the mixture of the polymer precursor and the additional material, and activating the carbonized mixture to form a multi-modal pore distribution activated carbon. The multi-modal pore distribution activated carbon can include pores less than 20 Å and greater than 30 Å or 500 Å depending upon the sorption properties desired, wherein the pore distribution of the activated carbon can be tailored to provide predetermined kinetics and/or gaseous constituent equilibrium isotherms. | 06-17-2010 |
| 20110100387 | CIGARETTES AND FILTER SUBASSEMBLIES WITH SQUEEZABLE FLAVOR CAPSULE AND METHODS OF MANUFACTURE - 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 capsule or capsules are provided between first and second absorbent members and the 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 and expose the additive material to mainstream smoke passing through the filter. The 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. An outer cover which is impermeable to the fluid within the capsules is provided about the capsule or capsules and the first and second absorbent members. | 05-05-2011 |
| 20110104218 | METHODS AND COMPOSITIONS FOR PRODUCING HYDROGEL CAPSULES COATED FOR LOW PERMEABILITY AND PHYSICAL INTEGRITY - Methods and compositions for producing hydrogel capsules enveloped with at least one coating layer is disclosed. The coating formulations deposited on the surface of the capsules can improve the physical integrity and the water-retention properties of the alginate beads. The coating formulations can be sequentially applied in various combinations to obtain desirable properties, such as improved physical integrity, mechanical strength, and low permeability, that can extend the shelf-life of the capsules when incorporated into various consumer products. | 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 |
