Abstract: The invention relates to a smoking article (1) having a high proportion of non-combustible, inorganic material and a relatively low level of visible sidestream. The smoking article includes a substantially non-combustible, wrapper (5) which extends along the full length of the smoking material rod and enwraps a combustible fuel source (6) and aerosol generator (7), both of which extend substantially along the length of the smoking material rod. Various suitable fuel source systems and aerosol generating systems are described. The article has a visible burn line which advances along the article and produces an ash which can be removed by the smoker in the normal way.

Abstract: A cigarette is provided with a filter comprising a filter element of water-disintegratable paper. The paper is water swellable and/or the filter element comprises a water swellable agent. Tipping which interattaches the filter to the tobacco rod of the cigarette is anchored by means of water susceptible adhesive. Thus when the cigarette comes into contact with sufficient water, the filter element swells and the tipping opens away from the filter. This facilitates disintegration of the water-disintegratable paper.
Abstract: The invention relates to a method of detecting the particles of a tobacco particle stream in the production of smokable articles by scanning by means of a fine-beam light barrier, the diameter of which is smaller than the dimensions of the tobacco particles, and from the distribution of the dimensions of the tobacco particles determined by darkening of the fine-beam light barrier.

Abstract: A rigid pack of smoking articles is made to have improved shelf life and to be resealable. A barrier material is sealed around the rigid pack. The rigid pack has a potential or actual access aperture extending from a top face into a major face. The barrier material has a line of severance or weakening defining a flap, which is in register with the potential or actual access aperture. Over the flap is a layer which overlaps it on each severable side with a portion having permanently-tacky adhesive. A non-adhered pull tab is preferably provided on the layer. To open the pack the user lifts the flap and if necessary the access aperture. After removal of a smoking article the gap in the barrier layer is reclosed and released by the repositioning of the adhesive layer, carrying with it the flap of barrier material. A machine for assembling the pack is also disclosed.

Abstract: The invention relates to a smokable filler material which attempts to mimic tobacco leaf in its simplest components in order to provide a simpler smoke to the smoker. The smokable filler material comprises aerosol generating means, a substantially non-combustible inorganic filler, a binder and an extract from a flavorful fuel source material. It may also comprise a biopolymer.
Abstract: A smokeable filler material which includes casing material as a fuel material, along with an inorganic filler, a binder and an aerosol generating source. This material has good taste and flavour characteristics and contains relatively little tobacco material.

Abstract: The invention relates to low delivery cigarettes, usually having a mainstream particulate matter delivery of about 9 mg or less. An embodiment has a rod of tobacco material and a filter element. The filter element is an alkali filter material section having a loading level of less than 12% by weight of the section. The characteristics of the cigarettes are arranged so that, when smoked, the alkaline filter material is exposed to an amount of smoke acceptable to achieve an increased perception of smoke impact.

Abstract: A hinge lid cigarette packet has an upper lid and a lower lid. The packet is constructed from a blank which is of a configuration which is symmetrical about the longitudinal centerline thereof. The upper lid is formed, in conventional fashion, of specifically lid panels of the blank, whereas the lower lid is formed of portions of what in a conventional single hinge lid packet are body panels. In order for the second lid to be moved from its closed position on the first opening thereof, front and side panels of the lid are separated at lines of weakening from bounding body panels.
