A smoking device including a tubular element containing tobacco and a filtering element connected to an end of the tubular element. The filtering element includes at least one breakable flavouring capsule which includes at least one core having at least one lipophilic substance and at least one flavouring agent dispersed or dissolved in the lipophilic substance; at least one breakable coating which coats the core and which has at least one chitosan having a weight average molecular weight (Mw) between 25 kDa and 400 kDa. Preferably, the breakable coating further includes at least one polyhydroxyalkanoate (PHA). The frangible coating that coats the core is able to preserve its hardness, and therefore its breakability, during use by the smoker, i.e. in the presence of humidity and heat that develop from the combustion of tobacco.

An aerosol-generating article includes a charge of aerosol-generating material arranged in a container, wherein the aerosol-generating material is provided in a form of shaped individual elements including a foam-like material. The aerosol-generating article further includes a sealing portion provided to one longitudinal end of the container, and made of an air permeable material and/or having an air permeable structure such that air is capable of flowing therethrough.

The disclosure provides a composition including nanocellulose and at least one active ingredient. Further provided is a fleece material including a nonwoven fabric and nanocellulose. The nanocellulose may be cellulose nanofibrils, nanocrystalline cellulose, or bacterial cellulose.

A cooling cigarette filter and a smoking product are provided. The cooling cigarette filter comprises a cooling section. The cooling section is provided with one or more channels connecting two ends of the cooling section, and an inner surface of each channel is coated with a cooling material. The cooling material comprises an inorganic phase change material and PEG, and the inorganic phase change material comprises at least one of Na2CO3.10H2O, CH3COONa.3H2O, CaCl2.4H2O, and Na2SO4.10H2O. The cooling cigarette filter has the advantages of ensuring the amount of smoke and lowering the temperature of the smoke entering the mouth, especially in the cooling section. Through the combination design of the structure of the cooling stick and the type and amount of the cooling material, the smoke can flow out of a smoke generation section rapidly and smoothly.

A cooling cigarette filter and a cigarette are disclosed. The cooling cigarette filter comprises a cooling section (2). The cooling section (2) comprises a cooling stick (201) formed from paper (5). The cooling stick (201) has one or more holes (202) communicating two ends of the cooling stick. And the surface of the paper (5) is coated with a cooling material. The cooling cigarette filter has the advantages of ensuring the amount of smoke and lowering the temperature of the smoke entering the mouth. Through the combination design of the structure of the cooling stick and the type and amount of the cooling material, the smoke can flow out of a smoke generation section rapidly and smoothly And the temperature of the high-temperature smoke before entering the mouth can be significantly lowered, thereby improving the comfort and satisfaction of smoking.

A filter part (1, 1) for use in an aerosol generating article and a method of manufacturing the filter part (1, 1). The filter part (1, 1) includes an aerosol permeable core (2) within a sleeve (3) formed integrally therearound. The core (2) is shorter than the integrally formed sleeve (3). The method includes conveying a plurality of aerosol permeable cores (2) along a conveying path at a first speed (S1) and forming a sleeve (3) around each core (2) at a second speed (S2). The second speed (S2) is greater than the first speed (S1) to generate a space between consecutive cores (2) within the sleeve (3).

A filter part (1, 1) for use in an aerosol generating article and a method of manufacturing the filter part (1, 1). The filter part (1, 1) includes an aerosol permeable core extrusion (2) surrounded by a sleeve (3) formed of predominantly linear, axially oriented fibres. The method includes forming two or more strips (4a, 4b) into segments surrounding a conveying path, bringing the segments together into a sleeve former (7) to form the sleeve (3) and introducing an aerosol permeable core extrusion (80) between the segments upstream of the sleeve former (7) and bonding the segments together to form a sleeve surrounding the core extrusion (80), thereby forming a filter rod (9). The filter rod (9) is then cut to form the filter part (1, 1).

A smoking article component comprising a viscoelastic material (500).

A smoking article (10) incorporates a liquid release component (20), the liquid release component comprising an inner core of a sustained release liquid delivery material and a frangible outer shell encapsulating the inner core. The liquid delivery material comprises a closed matrix structure comprising a cross-linked polymer matrix defining a plurality of domains; and a liquid composition that is trapped within the domains and is releasable from the closed matrix structure upon compression of the material. The frangible outer coating comprises at least one film-forming polymer and at least one plasticiser.
