  • Patent number: 9101165
    Abstract: A cigarette includes a tobacco rod in which a tobacco filler containing cut tobacco is wrapped with a cigarette paper, the tobacco rod being constituted by a distal end portion, a proximal end portion and a center portion, and a filter, the proximal end portion being connected to the filter. The distal end portion includes a volatile flavor-containing material incorporated in a gel of a polysaccharide, the center portion includes or does not include the volatile flavor-containing material, the proximal end portion includes or does not include the volatile flavor-containing material, and there is no case where both the center portion and the proximal end portion include the volatile flavor-containing material.

  • Patent number: 6782892
    Abstract: Cut filler compositions, cigarettes, methods for making cigarettes and methods for smoking cigarettes which involve the use of manganese oxide mixtures that include nanoparticle manganese oxide and other nanoparticle additive(s) capable of converting carbon monoxide to carbon dioxide and/or converting nitric oxide to nitrogen. The compositions, articles and methods of the invention can be used to reduce the amount of carbon monoxide and/or nitric oxide present in mainstream smoke reaching the smoker and/or given off in secondhand smoke. The manganese oxide can be co-precipitated with the additive(s), or mechanically mixed with the additive(s) to form the manganese oxide mixture. The manganese oxide may have a lower light-off temperature than the additive, such that during smoking of the cigarette, the heat generated from the oxidation of carbon monoxide by manganese oxide is capable of activating the additive. The additive may include iron oxide (Fe2O3) nanoparticles.

  • Patent number: 6732740
    Abstract: The filler of a cigarette rod has a tubular portion made of shredded tobacco and surrounding at least one row of spherical inserts made of aromatic material or aerosol. The tubular portion is made by feeding tobacco shreds against the underside of the horizontal lower reach of a foraminous conveyor belt advancing beneath a suction chamber to accumulate a first layer of shreds. The inserts are delivered to the underside of the first layer and are attracted thereto by suction. A second layer of shredded tobacco is assembled by showering shreds against the underside of the first layer where the second layer underlies the spherical inserts. The thus obtained filler is draped into a web of wrapping material to form a cigarette rod ready to be subdivided into sections of unit or multiple unit length. The spherical inserts are expelled from a revolving receptacle under the action of centrifugal force to form a row which is conveyed toward the underside of and advances with the first layer.

  • Patent number: 6443160
    Abstract: The invention relates to a method for forming a cigarette rod containing an additive material in a cigarette making machine, in which a continuous tobacco rod is fed along a vacuum conveyor and particles of the additive material are fed to and incorporated along the axis of the cigarette rod by a distributor which comprises a conveyor having a hollow drum with a cylindrical side wall on which there is a plurality of seats designed to house the particles; the drum rotating within a ring-shaped structure and the seats, during rotation of the drum, passing through an ejector unit designed to eject the particles from the seats and incorporate them in the tobacco rod through a feed pipe, so as to control the distribution of the particles of the additive material along the tobacco rod, obtaining a preset positioning of the particles in each cigarette length.

  • Patent number: 5052412
    Abstract: In a method of making lengths of smoking-material rod, particularly cigaret lengths, smoking material and wrapper-web material are each continuously fed to a rod maker operable to wrap and seam-seal the wrapper material about the smoking material to provide smoking material rod which is then fed to a cutter for cutting the rod into lengths. Smoke-modifying agent is applied by spray intermittently to one of the materials during their feeding to the rod maker so that, in each of the lengths, the smoke-modifying agent is distributed over one end zone which is accounted for by a few puffs, in the smoking of the length. The smoke modifying agent is of low volatility and low porosity migration.

  • Patent number: 5012823
    Abstract: A method and apparatus are disclosed for applying foamed material to tobacco, and for drying and setting the foamed material, particularly in connection with the making of cigarettes. The foamed material may be added to the tobacco, for example, in the paper guide section of a cigarette maker, at the garniture mouth or through the short tongue or through both, or at the chimney. Drying and setting can occur in the chimney, on the vacuum belt, or in the garniture, after the material has been applied to the tobacco filler. Drying can be accomplished, for example, by using heated air or microwave radiation. Addition of material to tobacco filler, during the cigarette making process in the form of a foam, results in a cigarette in which the material added is more uniformly distributed.

  • Patent number: 4995405
    Abstract: Aromatized liquid is introduced into the tobacco in the area of the settling path (AS) at a point at which nearly half the final tobacco layer has accumulated. Subsequently, the second half will settle thereon so that the inserted liquid is inside the final tobacco layer (15). Liquid is injected into the tobacco without the use of compressed air, thus excluding crystal formation. The injection rate of liquid is controlled responsive to the operating speed of the cigarette making machine.

  • Patent number: 4967772
    Abstract: A tobacco smoking article including smoking tobacco held in a container and an alcohol supported by the container. The alcohol has two or more carbon atoms and is capable when the vapor thereof is inhaled by the smoker of inhibiting the selective localization of nitrosamines and metabolites thereof in the smoker's tissues, such as those of the bronchial epithelium. The alcohol is associated with the smoking tobacco such that, when the tobacco is smoked, the vapors of the alcohol are inhaled in the tobacco smoke stream. The alcohol is present in an amount sufficient to inhibit the selective localization but not to produce any toxic side effects in the smoker.

  • Patent number: 4966169
    Abstract: A process for manufacturing cigarettes which imposes reduced health risks to the smokers thereof. According to this process redried cut rag tobacco is directly sprayed with one or more pre-selected alcohols which are capable, when the vapors thereof are inhaled by the smoker, of inhibiting or blocking the selective localization of at least one nitrosamine and/or a metabolite thereof in the smoker's tissues such as those of the epithelial lining of his lungs. An example of such an alcohol is cyclohexanol in an ethyl alcohol solution. After the alcohol solution has been sprayed on the tobacco, preferably as it tumbles in the cooler cylinder of the mechanized cigarette making line, and allowed to dry, the tobacco is made or machined in a conventional manner into the final cigarette, either filtered or unfiltered.

  • Patent number: 4913166
    Abstract: In order to provide when smoking a cigarette a substantially uniform concentration of the flavoring substance or substances supplied to the tobacco rod (23) in the form of at least one flavoring substance, the flow of flavoring substance is controlled, in accordance with the invention, periodically between a maximum and a minimum flow. The maximum flow is applied to those parts (36) of the tobacco rod which each include the tip-end of a cigarette, whereas the minimum flow is applied to the opposite end part (37) of the cigarette.

  • Patent number: 4898187
    Abstract: Loss of tobacco from the ends of cigarettes is reduced or prevented by applying foamed adhesive thereto. The foam may in general be blown onto the cigarette ends [(FIGS. 1, 2 and 4)] or may be "printed" onto the cigarette ends [(FIG. 3 and FIGS. 5 and 6)]. The expansion ratio of the foam in preferably at least 10:1, so that very little liquid adhesive is needed to contact a significant area of tobacco. Thus the liquid content of the adhesive may be readily absorbed into the tobacco so as not to create a drying problem. In a preferred example [(FIG. 1)] foam is supplied by a pipe [24] to fill apertures on a disc [20] from which measured quantities of foam are blown by an air jet from a pipe [28.] Suction is applied to the filter ends [108]of the cigarettes via a manifold [18] and flexible seals [12C] to help in drawing the foam into the cigarettes.
