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.

The invention discloses a variable-ventilation filter tip and a cigarette. The filter tip includes a filter element and a coating layer. The coating layer wraps the filter element. The filter element includes a smoke inlet end and a smoke release end. A phase-change ventilation area and a non-phase-change ventilation area are arranged on the coating layer, a plurality of first ventilation holes are arranged in the phase-change ventilation area, and a plurality of second ventilation holes are arranged in the non-phase-change ventilation area. Outside air penetrates through the coating layer through the first ventilation holes and the second ventilation holes to enter a part of the filter element. A part in the filter element close to the smoke inlet end is provided with a starch tube. A phase-change material is filled in the first ventilation hole. A phase-change temperature of the phase-change material ranges from 45° C. to 60° C.

A smoking article has an outer surface and a plurality of frangible microcapsules provided on the outer surface, wherein the microcapsules are capable of being manually ruptured by a consumer to release an odorant encapsulated therein. The smoking article preferably comprises a wrapped tobacco rod; and a filter attached to the wrapped tobacco rod by tipping paper, a mouth end portion of which is “over tipped” with a band or strip of “Peel and Sniff” microcapsules and/or a band or strip of “Scratch and Sniff” microcapsules.

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.

A starch-based cooling material of the invention is prepared by 8.0 to 9.0 parts of a starch, 0.5 to 1.0 part of a phase change material, and 0.5 to 1.0 a part of polyol. The starch-based cooling material of the invention is prepared by coordination of the starch, the phase change material and the polyol, wherein the phase change material has effects of absorbing and storing heat, a temperature of smoke can be significantly reduced, an effect of fast and strong cooling is realized, and a cooling effect can reach 70° C. to 120° C. All the raw materials for preparing are biodegradable materials, and a prepared heat-not-burn cigarette filter stick can be degraded after use, which is environmental friendly, and can be widely used in the field of preparing heat-not-burning cigarette products.

A cellulose acetate particle aggregate, a preparation method therefor and an application thereof, which relate to the field of harm reduction additives in cigarettes. The cellulose acetate particle aggregate includes 49-99.5 wt % of cellulose acetate particles, 0-50 wt % of a second kind of particles, and 0.5-20 wt % of a binder. The preparation method involves selecting cellulose acetate particles and a second kind of particles in a certain ratio, or cellulose acetate particles alone, preparing particle aggregates by using an air fluidized granulation method while adding a binder thereto, and sieving the particle aggregates to obtain a cellulose acetate particle aggregate having a required particle size. The cellulose acetate particle aggregate has a porous structure, an irregular shape, and a rough and uneven surface, which help to improve the efficiency of filtering out particulate matters or one or more harmful ingredients in cigarette smoke.

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.

A gel composition and tobacco industry products including the same The present invention relates to a gel composition comprising a gel formed from a liquid gel precursor and a gas. The present invention also relates to tobacco industry products comprising a gel composition, a method of preparing a gel composition comprising a gas, use of a gel composition comprising trapped gas, and a kit for assembling a tobacco industry product comprising a gel composition.

A flavouring component (43) for a smoking article (50) comprising a rod (33) of flavouring material (17). The flavouring material (17) comprises a carrier material (15) and flavouring particles (14) adhered to the carrier material (15) by means of a binder (13). The flavouring material (17) is formed by passing the carrier material (15) through a mixture (12) comprising the binder (13) and the flavouring particles (14). Also disclosed is a smoking article (50) including such a flavouring component (43), and an apparatus (10) and method for manufacturing such a flavouring component (43).

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.
