Abstract: A smokeless oral tobacco product is provided comprising an insoluble foamed material. The insoluble foamed material is formed by combining a foaming agent, an agent capable of forming chemical cross-linkages and a cross-linking agent. A method of producing a smokeless oral tobacco product comprising an insoluble foamed material is also provided.

Abstract: A filter (3) for a smoking article (1) comprises one or more segments (4a, 4b, 4c) of filtration media and a substantially transparent wrapper (5). The one or more filter segments (4a, 4b, 4c) and the wrapper (5) define a recess or cavity in the filter (3). An anchoring adhesive (7) is provided to secure the one or more filter segments (4a, 4b, 4c) to the wrapper (5). The anchoring adhesive (7) is disposed exclusively between the wrapper (5) and portions of the one or more filter segments (4a, 4b, 4c) other than those corresponding to the recess or cavity.

Abstract: The invention relates to a smoking article incorporating a smoking material comprising three main components, namely a non-combustible inorganic filler, an alginic binder and aerosol generating means. The smoking material is combined with tobacco material, which may be treated with additional humectant, to provide a smoking article that has an aerosol transfer efficiency ratio of greater than 4.0.

Abstract: A smoking article (10) comprises a rod (12) of smokeable material and a filter (14) attached to one end of the rod. The filter comprises an elongate body of filter material (16) wrapped with a transparent plug wrap (18). A first tipping wrapper (20a) overlies the join between the rod and the filter to attach the filter to the rod. At least one additional tipping wrapper (20b) is provided around the filter, spaced from and separate to the first tipping wrapper such that a portion of the transparent plug wrap is exposed between the first and at least one additional tipping wrapper to define a window portion (22) through which the filter material is visible. A method of producing such a smoking article is also disclosed.

Abstract: The invention relates to smokable filler materials and a process for making same, the smokable filler material comprising a foaming agent, an agent capable of forming chemical cross-linkages, and a cross-linking agent. A combination of the foaming agent in the foamed state thereof, the agent capable of forming chemical crosslinkages and the cross-linking agent provides a stabilized, foamed material. The invention also provides a smoking article incorporating the smokable filler material of the invention.

Abstract: This invention relates to a smoking article having a controllable static burn rate by virtue of the particle size of a component of the smoking material thereof. The smoking material comprises a non-combustible inorganic filler, a binder, aerosol generating means, the non-combustible filler comprising a proportion of material having a mean particle size in the range of 500 ?m to 20 ?m.
