Abstract:
A printer and transport assembly (10) comprises a transport conveyor (16) for receiving individual blanks (12) and continuously conveying the blanks (12) in a downstream direction. A digital high speed printer (22) is positioned directly above the transport conveyor (16) downstream from where the blanks (12) are received on the transport conveyor (16) for printing high quality indicia on the dividual blanks as they are continuously conveyed downstream. A blank drying (28) arrangement receives printed blanks from the transport conveyor (16) and moves the blanks (12) in spaced relationship over a course of travel of sufficient length so as to sufficiently dry the printed indicia on the blanks (12). Ultimately, the dried printed blanks may be collected in a stack. Packaging, greeting cards, stickers, labels and coupons, for example, may be printed with the printer and transport assembly (10).
Abstract:
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. The invention also encompasses carbon beads having pores therein comprising a majority of the pores less than about 30A and a micropore volume calculated using Density Functional Theory (DFT) in the range of about 0.2cm3/g to 1.0cm3/g for pores in the range of about 5A to 10A. The invention also encompasses a smoking article filter comprising such activated carbon beads, a method for making such a filter and a method for making a smoking article including such a filter.
Abstract:
A smoking article 10 has a cylinder 20 of smoking material and a central tube 60 within the cylinder of the smoking material wherein heat is convectively transferred with smoke from a lit end of the cylinder of smoking material through the central tube to a mouth end of the cylinder of smoking material in each puff. A filter system 40 is attached to the cylinder of smoking material, and includes a plurality of segments, wherein at least one of the plurality of segments contains flavorant 72 and aerosol forming agents 74 encapsulated in at least one breakable capsule 70.
Abstract:
Provided is a method of encapsulating a hydrophilic substance (20) 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 (20) into a stream of molten wax (25) and allowing the droplet to pass through the molten wax (25) to enter a container of water (30). The wax capsule (35) forms an oral product that may be placed in the mouth or used in conjunction with other edible or oral products.
Abstract:
A smoking article (10) having a cylindrical tube (22) of smokable material (21) having an outer wrapper (30) , a concentric rod (24) of smokable material (21) coaxially positioned within the cylindrical tube (22) of a smokable material (21) , and an inner wrapper (60) separating the cylindrical tube (22) and the concentric rod (24) . A filter (40) attaches to the tobacco rod (20) with an annular film (70) positioned between the filter (40) and the tobacco rod (20) . The annular film (70) increases the resistance-to-draw of the cylindrical tube (22) during smoking.
Abstract:
A method for providing an encapsulated flavorant or chemesthetic agent in a smoking article comprises forming an emulsion comprising: (i) a first aqueous solution, comprising one or more cross-linkable polysaccharides; and (ii) a hydrophobic additive comprising one or more flavorants or chemesthetic agents. The method also comprises extruding the emulsion into a second aqueous solution in the form of an elongated structure, cross-linking at least a portion of the one or more cross-linkable polysaccharides, removing the cross-linked elongated structure from the second aqueous solution, introducing the cross-linked elongated structure into a filter, or into a rod comprising a smoking composition, or both; and forming the filter or the rod of the smoking composition into a smoking article. The method can include a drying step. A smoking article comprising a rod comprising a smokable composition; and one or more cross-linked elongated structures produced by the method of the invention is also disclosed. A smokable material comprising tobacco and one or more cross-linked elongated structures produced by the method of the invention is also disclosed.
Abstract:
A smoking article 10 includes a cylinder 20 of smoking material 21 having at least one hollow tube 60 having a heat conductive wall 68 within the cylinder of smoking material and a filter system attached to the cylinder of smoking material. The filter system 40 includes an adsorbent material 76 therein. The at least one hollow tube extends from within the cylinder of smoking material through the adsorbent material. At least one flavorant material 80 is retained within the at least one hollow tube, and upon exposure to heat from the heat conductive wall of the hollow tube the flavorant material releases a flavorant.
Abstract:
Cigarettes are provided which contain a filtering system (180) and flavorants encapsulated with polyvinyl acetate (150), wherein deactivation of a sorbent by the flavorant is reduced through the encapsulation of the flavorant within the polyvinyl acetate. A preferred flavorant is menthol. The encapsulated flavorants are prepared by mixing at least one flavorant with polyvinyl acetate and a solvent, such as ethanol, and forming the encapsulated flavorants. Methods of making cigarettes and smoking the articles are also provided.
