    摘要: A smoking article comprises a rod of smoking material, wrapped in a wrapper, in which rod the packing density of the smoking material varies continuously along at least a major portion of the overall length of the rod, but is constant across any section, within said portion, in a plane perpendicular to the longitudinal axis. The smoking material may be of homogeneous constitution throughout the rod. Preferably the density decreases continuously along the said portion of the rod in the direction away from the end of the rod to be lit, from which end the said portion may extend to substantially the other end of the rod. There may be between a 5% and a 40% weight difference between the more dense half of the length of the rod and the less dense half thereof. The density at the less dense end of the rod may be in the range of 170 to 240 mg cm.sup.-3 and that at the denser end in the range of 290 to 350 mg cm.sup.-3.

    摘要: A method for obtaining a smoking material additive which is a smoke-aroma precursor comprises the steps of removing surface gum, preferably surface gum only, from Nicotinia plant leaves or flowers and subjecting the gum to a partition or purification process whereby a diterpene fraction constituting the said precursor and a fraction containing undesirable lipids are obtained, the latter fraction being discarded. The gum may be removed by solvent washing, suitably with chloroform. The partition or purification step may be a two-phase solvent partition process, for example using a hexane/aqueous methanol system.

    摘要: A cigarette making machine is provided with a pressure drop measuring unit (1) located at or close to the garniture of the making machine. The pressure drop of a gas stream of constant volume is introduced into the compacted tobacco rod beneath the format finger (2) on the making machine at a point at which that pressure drop measurement correlates with the bound pressure drop of the finished cigarette. The unbound cigarette pressure drop or draw resistance experienced by the smoker can be calculated using the bound tobacco rod pressure drop obtained by correlation with the measured pressure drop across the rod in an algorithim processed by calculation means. The degree of ventilation of the cigarette may also be utilised in the algorithim calculation. Comparator means allows the unbound cigarette pressure drop to be maintained within pre-set limits by varying cigarette parameters which affect the overall unbound cigarette pressure drop.

    摘要: This invention provides a smoking article having reduced sidestream smoke in the inter-puff period. A smoking article according to the invention may have segments of a high level of tobacco-containing material interconnected by segments of low level of tobacco-containing material which are capable of maintaining smoulder in the inter-puff period and re-igniting the segments of a high level of tobacco-containing material in the puff period. Alternatively, a smoking article according to another aspect of the invention may have a lengthwise, axially extending, tobacco-containing fuse portion which sustains smoulder in the inter-puff period when surrounding tobacco material is substantially extinguished and which re-ignites the extinguished material on puffing of the smoking article.

    摘要: This invention relates to methods of increasing the viscosity of a dispersion containing an alginate by subjecting the dispersion to high shear, such as the shear in a laboratory valve homogeniser. The viscosity of the dispersion increases within the range of two fold to five hundred fold.The method of increasing viscosity is useful in tobacco reconstitution or tobacco substitut processes, especially where either low levels of binder are required or improved taste characteristics over cellulosic binders, for example, are important.

    摘要: Apparatus for measuring the stiffness of creases of a packet blank comprises first and second spaced apart guides, on which a flat blank may be supported, and a plunger which is movable between the guides to deform the blank about a crease(s). The plunger brings part of the blank into contact with a bearing surface, and a panel(s) bent relatively of that part rests against force measuring means. The force measuring means provides a signal indicative of the resistance to bending of a crease about which the panel(s) has been bent.

    摘要: A smoking article comprises a wrapped rod of smoking material, a filter element and a tipping wrapper by which the rod and filter element are interattached. The filter element comprises a body of fibrous filtration material and paper wrapper securing the filtration material. Opening means is provided in the paper wrapper extending longitudinally along the filter element and providing at least one ventillation-air distribution space bounded by the tipping wrapper. Ventilation air is permitted to ingress into the space at a first location, whereby air may flow through the space and then to enter the filtration material at a second location spaced longitudinally from the filter element. The smoking article of the invention has a number of advantages and represents an advance in the art in that it makes possible a more direct and better distributed flow of ventilation air into wrapped filter elements of smoking articles containing such elements.

    摘要: A smoking article mouthpiece element comprises a first portion within which a smoke-passage and a ventilation-duct extends from end-to-end of the portion, a downstream end of the duct being spaced from the periphery of the first portion and the wall and the walls of the duct being gas impervious and a second portion disposed at the end of the first portion being in smoke-flow communication with the smoke passage of the first portion, and gas-impervious wall at the end of said second portion closer to the first portion extending inwardly from a first location at the periphery of the element to a second location at the side of the upstream end of the duct further from the first location, the wall bounding a cavity in communication with the duct and segregated from the interior of the second portion. The first and second portions may form respective parts of an integral unit or may be discrete components disposed in end-to-end abutment. The aforesaid wall is suitably part of the second portion.Smoke filtration material may be disposed in the smoke passage and/or in the interior of the second portion. The ventilation-duct, which advantageously extends substantially parallel to the longitudinal axis of the first portion, may be one of a plurality of similar duct or ducts.A smoking article according to the invention may thus comprise a smoking-material rod, a mouthpiece element with a cavity as aforesaid and a wrapper extending about said mouthpiece element and providing for ingress of air to said cavity. The ratio of the velocity of air issuing from the mouth end of said ventilation-duct means to the velocity of smoke issuing from the mouth end of said smoke-passage means being in excess of at least ten, and possibly in excess of twenty when said smoking article is smoked under standard machine-smoking conditions.In detail, a smoking article mouthpiece element may be substantially as hereinbefore described with reference to FIGS. 1, 2 and 3 or FIGS. 4 and 5 or FIGS. 6 and 7 of the drawing.
