Abstract: Smoke constituent reduction is achieved by resolving from puff-to-puff analysis at which location along a tobacco rod production of a particular smoke constituent is maximized, and locally applying an attenuator at said resolved location to reduce production of the constituent. A remainder of the rod is left untreated so as to minimize impact on taste and burn characteristics of the cigarette. Reduction of the first puff formaldehyde formation is achieved by treating the cigarette tip with salts, using Burley tobacco in the tip, increasing the rod density, ventilation at the tip, and thermal treatment of the tip. Other classes of smoke constituents such as TSNAs (tobacco specific nitrosamines), PAHs (polycyclic aromatic hydrocarbons), etc., in particular the PAHs of naphthalene, phenanthrene, pyrene, flouranthene and benzo(a)pyrene may be reduced with placement of a carbon-based and/or metallic disc at the tip and with practices of the invention herein.

Abstract: The present invention is generally directed to high opacity cigarette wrapping papers. The wrapping paper made according to the present invention contains a mixture of a white pigment and a black pigment. The white pigment, which can be, for instance, calcium carbonate, has a median particle size of from about 0.1 microns to about 0.5 microns, and particularly from about 0.2 microns to about 0.4 microns. It has been discovered that this particular particle size range, which is equal to one-half the wavelength of visible light, greatly increases the opacity, brightness and whiteness of the paper. Small amounts of a black pigment, such as carbon, are then added to further increase the opacity without significantly decreasing the whiteness or brightness of the paper relative to conventional cigarette paper.

Abstract: The present invention is generally directed to low weight cigarette wrapping papers. In particular, the wrapping papers, although having a low basis weight, have an opacity of at least 70% and a tensile strength comparable with conventional papers. Wrapping papers made according to the present invention contain a white pigment having a medium particle size of from 0.1 microns to about 0.5 microns. In one embodiment, a black pigment can also be combined with the white pigment in small amounts.

Abstract: A tobacco product consists of a preportioned tobacco strand (10) surrounded by a preformed tubular cigarette paper wrapper (11; 17). The tobacco strand is formed of individual tobacco fibers which are interconnected to each other by a binding agent to form a dimensionally stable tobacco strand. The binding agent and the fibers are each smokable but the outer surface of the tubular dimensionally stable tobacco strand is air pervious so that the strand as such is not directly smokable. The dimensionally stable strand (10) is inserted into the preformed tubular cigarette paper wrapper (11) to form a smokable cigarette. The one end of the strand is tapered for easier insertion of the strand into the preformed cigarette paper wrapper.

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 foam, results in a cigarette in which the material added is more uniformly distributed.

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.

Abstract: A cigarette substitute is provided which satisfies the smokers psychological and pharmacological need for a cigarette, without exposing him, or others, to the ill-effects associated with inhalation of smoke, tar and other combustion products. This cigarette substitute is a smokeless cigarette designed to satisfy the smokers physical and pharmacological needs of nicotine, without sujecting either the smoker, or others in his immediate vicinity, to exposure to cigarette smoke. It is also intended to satisfy the smoker's psychological needs of having something to occupy the hands and/or mouth and to simulate the act of puffing on a cigarette.

Abstract: A smoking article in the form of a filter cigarette can have adjustable air dilution capabilities. The filter element is movable toward and away from the tobacco rod along the longitudinal axis of the cigarette. Perforations in the tipping material of the cigarette expose the inner region of the cigarette and provide air dilution capabilities when the filter element and tobacco rod are in a spaced apart relationship. When the filter element and the tobacco rod are in a substantially abutting relationship, the perforations in the tipping material overlie a substantially air impermeable region of the tobacco rod thereby providing a low or non air diluted cigarette.

Abstract: A filter for a cigarette includes a porous filter rod circumscribed by a non-porous or air impermeable wrapper, and ventilating air grooves embedded in the wrapped filter rod which extend from one end of the filter rod a preselected distance generally longitudinally thereof. The ends of the grooves are recessed a predetermined distance or depth inwardly of the end of the filter rod and communicate with radially extending open channels formed in the one end of the filter rod. An air permeable tipping material circumscribes the wrapped filter rod which provides a path for ventilating air flow into the grooves. Due to the air impermeable wrapper, the air flowing in the grooves is segregated from the smoke flowing through the filter rod so that ventilating air is the only substance flowing in the grooves.

Abstract: An improved tobacco smoke filter is characterized by an undiluted air passage formed between a smoke-impervious plug wrap and an air-impervious tipping wrap by loosely wrapping the tipping wrap about the plug wrap along a section of the filter extending from its smoke discharge end. In a preferred embodiment, the loose wrapping is effected by reducing the cross-sectional perimeter of the rod and plug wrap along the aforesaid section while keeping the tip of the cross-sectional perimeter substantially constant throughout its length. A raised lip is provided at the smoke discharging end of the rod and plug wrap to define a cigarette holder in the filter. For circumstances where the cross-section of the filter plug becomes too complex for adherence of the tipping paper, heat shrinkable film can be laminated in the tipping paper so that after the entire cigarette is assembled, it can be subjected to heat and cause the tipping paper to shrink to the appropriate size.

Abstract: A filter for tobacco smoke comprises a porous substrate which has a deposit thereon of particles which are crystalline, positively charged at the pH of tobacco smoke, water-insoluble, hydrophobic, and oleophilic to provide a coalescing agent which acts to attract and neutralize the negatively charged particles which are dispersed in tobacco smoke. To increase the effectiveness of the filter, the tobacco has mixed therewith and deposited thereon particles of a water-insoluble, hydrophobic, moisture-laden, negative charge-imparting substance. Cigarettes made with tobacco thus treated furnish a number of advantages without being associated with the filter of the invention.

Abstract: A filter for a cigarette includes a porous filter rod circumscribed by a non-porous wrapper wherein the filter rod with the non-porous wrapper therearound is provided with grooves extending from one end thereof a preselected distance longitudinally therealong.
