A smoking article (10) incorporates a mouthpiece (14), the mouthpiece includes an open pore structure converted from an organic gel and a functional material dispersed in the open pore structure, such as aerogel particles (20).

The present disclosure relates to a flavor delivery device and a cartridge that includes such flavor delivery device. The flavor delivery device includes a flavor substrate that can be formed of a porous material, and further including flavor material included within the flavor substrate. The flavor substrate is surrounded by an outer sleeve which is impermeable to the flavor material. The flavor delivery device may be positioned within a cartridge of an aerosol delivery device where the flavor delivery device is located downstream from a reservoir containing an aerosol precursor composition relative to the mouthend of the cartridge.

Smoking article additive-containing member An additive-containing member having first and second regions, the second region comprising a predetermined region having a reduced strength limit relative to the first region so that the predetermined region is caused to break when pressure is applied to the additive-containing member, thereby to release additive, wherein the predetermined region is at a seal between two parts of the additive-containing member.

A method of manufacturing flavorant particles includes melting a food grade wax and a flavorant into a molten wax; solidifying the molten wax; and grinding the solidified molten wax into a plurality of flavorant particles. Another method of manufacturing flavorant particles includes melting a food grade wax and a flavorant into a molten wax, the molten wax having a melting temperature between about 50° C. to about 70° C.; and spray-chilling the molten wax into at least one solid flavorant particle, the solid flavorant particle having a diameter of between about 0.1 mm to about 2.0 mm.

There is provided a filter for a smoking article. The filter comprises a filter segment comprising filter material, and the filter segment has a cross sectional area measured perpendicular to the longitudinal direction of the filter. The filter further comprises a flavour delivery member embedded in the filter segment and surrounded on all sides by the filter material. The flavour delivery member comprises structural material enclosing liquid flavourant for flavouring smoke during smoking of a smoking article provided with the filter, and the flavour delivery member releases at least a portion of the liquid flavourant when the filter is subjected to external force. The cross sectional area of the flavour delivery member measured perpendicular to the longitudinal direction of the filter is about 30% of the cross sectional area of the filter segment or greater.

A disposable inhalation device that releases smoke which is not directly inhaled is provided. The body of the device is in the form of a cylinder formed by a sheath of thin material and is composed of three components that function independently of one another: an inhalation section, organic matter combustion section and a splitting section. The splitting section separates the inhalation section and the organic matter combustion section. Through the side apertures on the body of the inhalation section, the external atmospheric air enters the inhalation section during the inhalation process, where it mixes with the inhalation substance and the person inhales. By combustion of the organic matter together with the sheath of the organic matter combustion section, smoke is not inhaled directly by the inhaler i.e. the person who is inhaling.

A smoking article is provided that includes an aerogel, which can be optionally impregnated with a catalytic metal compound or can optionally be coated with at least one aerosol-forming material and a flavoring agent. The smoking article comprises various segments such as a heat generation segment, an aerosol-generation segment, and a mouth end. The aerogel can be placed near or within any of these segments.

The presence of the aerogel can reduce the concentration of certain gaseous components of mainstream smoke generated during use of a smoking article incorporating a heat generation segment containing a fuel element.

An article for use in a non-combustible aerosol provision system is described. The article includes an aerosol generating material and a mouthpiece connected to the aerosol generating material, the mouthpiece including a first body of material, and a second body of material downstream of the first body. The second body is offset from the first body so as to define a cavity between the first body and the second body. A breakable capsule is disposed in the cavity, and a diameter of the capsule can be less than the length of the cavity and the diameter of the cavity can be greater than the length of the cavity. A method of manufacturing an article is also described.

A smoking article includes a tobacco substrate and a filter segment comprising filtration material axially aligned in an abutting end to end relationship with the tobacco substrate. A hydrophobic plug wrap is disposed about the filtration material. The plug wrap is hydrophobic via hydrophobic groups chemically bonded to the plug wrap.

A filter (11) for a smoking article (10) comprises a first flow path (13) through the filter, a second flow path (14) through the filter, the second flow path being disposed around the first flow path, and a selector (16) for allowing flow selectively through the first and second flow paths.
