Improved delivery of additive materials to cigarettes is provided through the use of one or more capsules containing additive materials, such as flavor components, in the filter section of a cigarette. The capsule or capsules are between first and second absorbent members and the capsules are subjected to an external force, such as squeezing, by a smoker prior to or during smoking of the cigarette in order to release at least a portion of the additive material and expose the additive material to mainstream smoke passing through the filter. The capsules provide a barrier between the additive materials and other cigarettes components, such as sorbents or filter materials, in order to reduce additive material migration into the other cigarette components prior to desired use. An outer cover which is impermeable to the fluid within the capsules is provided about the capsule or capsules and the first and second absorbent members.

An electronic smoking article includes a liquid aerosol formulation, a heater operable to at least partially volatilize the liquid aerosol formulation and form an aerosol and a tubular filter segment downstream of the heater. The tubular filter segment is operable to selectively filter aerosol particles and vapors from the aerosol.

A smoking article (10) comprising: an aerosol-generating substrate (12) and a mouthpiece (14) secured to a downstream end of the aerosol-generating substrate (12). The mouthpiece (14) comprises a first segment (24) of elastically deformable material, the first segment (24) having a length in the longitudinal direction of the mouthpiece (14) and a width transverse to its length. The first segment (24) comprises an insert unit access portion comprising at least one slit (60) extending along at least a part of the length of the first segment (14), and extending across at least a part of the width of the first segment (14) to facilitate deformation of the access portion, such that an opening (25) is formable or expandable in the access portion of the first segment (14) upon receiving an insert unit (50).

Tobacco constituent releasing components comprising an agglomerated structure formed from a precursor composition comprising tobacco particles and one or more aerosol forming agents, processes for preparing tobacco constituent releasing components, and various tobacco industry products including the tobacco constituent releasing components.

[Problem] The present invention provides a capsule that is capable of suppressing volatilization of a highly volatile capsule content through the capsule shell and that is breakable.

[Solution] A breakable seamless capsule for a smoking equipment, comprising a content containing an oily ingredient and a capsule shell for encapsulating said content, wherein: the capsule shell contains a polysaccharide; the thickness of the capsule shell is 60 μm or more; the volatilization content (VC) of the content after leaving the content to stand under an environment at a temperature of 25° C. and a relative humidity of 40% for 4 hours is 3.0 wt % or more with respect to the total weight of the encapsulated content; and the crush strength per diameter of the capsule is 3-8 N/mm. In one embodiment, the crush strength per diameter of the capsule is 3.5-8 N/mm. In another embodiment, the capsule shell does not contain gelatin.

A filter for a smoking article or an aerosol generating product comprising a first filter section and a second filter section, the second filter section being located downstream of the first filter section; the first filter section comprising filter material and two or more capsules comprising additive, the capsules being disposed in an axial region proximal a longitudinal axis of the filter and being spaced in sequence in a direction along the axis; the second filter section comprising at least one channel located in an axial region of the second filter section proximal a longitudinal axis of the filter, to facilitate, in use, drawing of an aerosol through the axial region of the first filter section in which the capsules are disposed.

A smoking article includes a filter section including a filter material and at least one capsule including a shell. The capsule includes a liquid contained by the shell in the capsule, which further includes at least one carrier fluid and/or at least one flavored fluid arranged inside the crushable shell. The filter section includes a tobacco product, wherein the tobacco product includes tobacco particles with an average size of 30 μm or less. The tobacco product is arranged inside the filter material, in a plug wrap, in at least one wrapping and/or inside the capsule. A filter section including the tobacco product and a method of manufacturing a smoking article with such a filter section are also provided.

A smoking article includes a smokable material and a filter downstream of the smokable material. The filter comprises a capsule having a core and a breakable shell. The core has a mixture including one or more lipid compounds and one or more humectants. The lipid compounds account for 50% or more of the weight of the mixture. At least one of the one or more humectants is capable of interacting with one or more smoke constituents to reduce the concentration of the one or more smoke constituents in mainstream smoke.

An aerosol-generating amorphous solid comprising an active ingredient, wherein when a sheet of the aerosol-generating amorphous solid having an area of 43.1 mm.sup.2 and area density of 90 g/m.sup.2 is heated to 230° C. for a period of 3 seconds under a 1.1 L/min airflow, at least 50 wt % of the active ingredient is aerosolized.

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.
