A filter segment for use in a filter of a smoking article includes a substrate loaded with at least one smoke-modifying agent. The substrate is located within the body of the filter segment and is formed from filter plug wrap having an air permeability ranging from about 6,000 Coresta units to about 24,000 Coresta units.

There is provided an aerosol-generating article (10) comprising an aerosol-generating substrate (12) and a mouthpiece (14). The mouthpiece (14) comprises at least one segment of filter material (18, 20, 22), a breakable capsule (26) containing an aqueous liquid (32), and a plurality of microencapsulated flavourant particles (38) dispersed within the at least one segment of filter material (22). Each of the microencapsulated flavourant particles (38) comprises a flavourant encapsulated within a shell comprising a water sensitive material, such that the plurality of microencapsulated flavourant particles (38) are adapted to release a flavourant upon contact with the liquid (32) contained within the breakable capsule (26).

A smoking article includes smokable material, a filter downstream of the smokable material, and a breakable capsule (80). The filter is plasma treated or has an increased surface energy relative to standard filter material. The breakable capsule (80) includes a core surrounded by a frangible shell. The core contains a liquid composition comprising a sensory-enhancing agent. The breakable capsule is positioned to cause the liquid composition to contact the filter material (32) when the shell is ruptured.

There is provided an aerosol-generating 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 at least one segment of filter material (18) and a liquid delivery element (22). The liquid delivery element (22) comprises an upstream end and a downstream end, a cavity (28) containing a liquid, and at least one channel (26) extending between the upstream end and the downstream end of the liquid delivery element (22). The liquid delivery element (22) is arranged to deliver the liquid to the at least one segment of filter material (18) when activated by a consumer.

The present invention relates to a tobacco industry product component comprising a wall circumscribing a cavity. A plurality of additive capsules and a plurality of particles are disposed in the cavity. The particles are configured such that, in use, the particles promote breaking of the additive capsules upon the application of an external force to the wall of the tobacco industry product component by a user. The particles may comprise a material having a particle density of at least 1 g/cc. There is also provided a method of manufacturing a tobacco industry product component.

There is provided a flavour system for use in a tobacco industry product. The flavour system comprises lyophilised botanical material, an activator capable of releasing flavourant from the lyophilised botanical material through contact of the activator with the lyophilised botanical material, and a removable barrier preventing contact between the lyophilised botanical material and the activator. The barrier is removable to permit the activator to contact the lyophilised botanical material, thereby to cause release of the flavourant.

A breakable capsule such as a seamless breakable capsule useful in a smoking article or a smokeless tobacco product includes an outer shell formed of a cross-linked agar matrix including at least one filler, and an inner core surrounded by the outer shell which comprises a liquid or gel based composition of a flavorant and/or non-flavorant. The cross-linked agar matrix is reinforced with carboxymethyl cellulose that is dispersed throughout the agar matrix so as to fill empty spaces in the agar matrix and inhibit the composition from passing through the empty spaces of the agar matrix.

According to an exemplary embodiment, provided is an aerosol generation apparatus including: a liquid cartridge comprising a storage unit configured to store an aerosol-generating substrate which is liquid-type and an atomizer configured to generate aerosol by heating the aerosol-generating substrate; a mouth tip located at one end of the aerosol generation apparatus and comprising a filter unit configured to adsorb at least one material included in the generated aerosol; and an aerosol heating unit configured to heat the generated aerosol when the generated aerosol is inhaled by a user through the mouth tip.

Provided are an aerosol generating apparatus including a cigarette insertion portion into which a cigarette is insertable; and a vaporizer configured to heat a liquid composition to generate aerosol and discharge the generated aerosol toward the inserted cigarette such that the generated aerosol passes through the cigarette inserted into the cigarette insertion portion, and a cradle for receiving the aerosol generating apparatus.

Disclosed are an aerosol generating article and an aerosol generating device, wherein the aerosol generating article includes a tobacco rod and a cooling segment configured to cool aerosols generated from the tobacco rod through a tobacco composition.
