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 cooling element comprising a longitudinally extending substrate, the longitudinally extending substrate including an additive in an amount from 3% to 12% by total weight of the substrate, wherein the additive is selected from (i) propylene glycol, (ii) vegetable glycerin, (iii) propylene glycol and vegetable glycerin or (iv) propylene glycol and 2-isopropyl-N,2,3-trimethylbutyramide.

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.Math.10H2O, CH3COONa.Math.3H2O, CaCl2.Math.4H2O, and Na2SO4.Math.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 method for manufacturing a fragrance capsule of tobacco according to an embodiment of this disclosure may comprise: a membrane manufacturing step for manufacturing a membrane of a fragrance capsule by a membrane manufacturing part which manufactures a membrane; a capsule manufacturing step for manufacturing the fragrance capsule using an apparatus for manufacturing a capsule with the membrane manufactured during the membrane manufacturing step and a fragrance liquid to be held in the membrane; and a hardening step for hardening the fragrance capsule.

Disclosed are fibers which contain identification fibers. The identification fibers can comprise one or more chemical markers, or taggants, which may vary among the fibers or be incorporated throughout all of the fibers. The disclosure also relates to the method for making and characterizing the fibers. Characterization of the fibers can include identifying chemical markers and correlating the chemical markers and a taggant chemical marker amounts of at least one of the chemical markers to manufacturer-specific taggants to determine supply chain information. The supply chain information can be used to track the fibers from manufacturing through intermediaries, conversion to final product, and/or the consumer.

Objects of the present invention are to provide a mayenite compound which can induce electron donation reaction, H.sup. donation reaction, deoxygenation reaction, and dehydration reaction; a multifunctional agent which contains the mayenite compound which is not dissolved in a solvent, and which can induce electron donation reaction, H.sup. donation reaction, deoxygenation reaction, and dehydration reaction; and a method for producing a mayenite-compound-containing product. The invention provides a mayenite compound characterized by comprising enclosing electron and H.sup., a multifunctional agent characterized in that the agent contains at least one of the mayenite compound I and a mixture II of the mayenite compound enclosing electron and the mayenite compound enclosing H.sup., and exhibits radical scavenging activity, reducing property, deoxygenation performance, and dehydration performance; and a method for producing a mayenite-compound-containing product containing the aforementioned mayenite compound.

A tip for a smoking article such as a cigar is disclosed. The tip comprises a longitudinally extending element comprising a plurality of bicomponent fibers which define at least one channel extending longitudinally of the element.

An article for use with a smoking device that is configured to be insertable into a chamber defined in the smoking device. The article includes an air-permeable filter member that comprises plant-based material that permits a user to combust a smoking device's contents. Upon combustion of a smoking device's contents, the combustible smoking filter may also combust and be smoked.

There is provided an electronic vapor provision system comprising: a vaporizer for vaporizing liquid for inhalation by a user of the electronic vapor provision system; a power supply comprising a cell or battery for supplying power to the vaporizer; and a filter for filtering vaporized liquid prior to inhalation by the user of the electronic vapor provision system, wherein the filter can partially or completely remove from the vapor one or more aldehydes present in the vapor.

The present invention relates to an elongated smoking article (100) that extends in a longitudinal direction (L). The elongated smoking article (100) comprises a heatable tobacco material (11) and a filter element (20) aligned with the smoking body (10). The filter element (20) has at least one filter portion (30) and at least one hollow section (40), wherein the at least one hollow section (40) is disposed between the smoking body (10) and at least one of the at least one filer portion (30). The filter element (20) is sheathed by a tipping paper (50) together with the smoking body (10). The filter portion (30) comprises a material for reducing unwanted substances from an aerosol and a hollow section (40) has a barrier layer (51) disposed on its inner surface (41) and a carrier layer (52) disposed on the barrier layer (51). The carrier layer (52) contains a volatile additive (80) and the barrier layer (51) is impermeable to the volatile additive (80). The present invention also refers to a hollow section (40) for an elongated smoking article (100) of the invention, the hollow section (40) being spirally wound from a cardboard sheet material (42) comprising a barrier layer (51) disposed on its inner surface (41) and a carrier layer (52) disposed on the barrier layer (51), wherein a volatile additive (80) is contained in the carrier layer (52) and the barrier layer (51) is impermeable to the volatile additive (80).
