An aerosol generating article includes a first portion including an organic acid, a second portion including a nicotine freebase, a third portion including a cooling material, and a fourth portion including a filter material, wherein a nicotine salt is generated through an acid-base reaction of the organic acid and nicotine freebase that are vaporized by heating.

The invention relates to a cigarette filter. In particular, the present invention relates to a new cigarette filter, in which materials of natural origin are used that have not been applied in this special field before. More particularly, the present invention relates to a cigarette filter, which can be used for absorbing the toxic components of cigarette smoke, and lowering the tissue damage triggered by cigarette smoke on the respiratory organs, the cardiovascular system and the mucosa. Especially the present invention relates to a cigarette filter containing alginate.

A method of manufacturing a smoking article including a tube filter includes preparing a smoking material portion, a first tube filter flavored by a first flavoring liquid, and a mouthpiece flavored by a second flavoring liquid; and combining and packaging the smoking material portion, the first tube filter, and the mouthpiece with a wrapper, wherein the preparing comprises applying the first flavoring liquid inside the first tube filter through a hollow of the first tube filter.

An embodiment of the present disclosure provides a method of aging smoking materials for constituting at least a portion of a smoking material portion of a smoking article, the method including preparing an oak barrel and the smoking materials, putting the smoking materials into an inner space of the oak barrel, sealing the oak barrel, and aging the smoking materials.

A filtered smoking article includes an aerosol generation rod, a filter disposed at a downstream end of the aerosol generation rod, and tipping paper wrapped around a downstream end part of the aerosol generation rod and an outer circumferential surface of the filter and connecting the aerosol generation rod and the filter. The tipping paper is paper containing bleached pulp and unbleached pulp, and fibers of the unbleached pulp have a length of 1 mm to 4 mm and a thickness of 20 μm to 70 μm.

A smoking article provides one or more sheets of material that can be rolled to a tube or shell or tube-like shape and then packaged in an unfilled or partially filled condition, one end portion of the tube or shell or tube-like shape being at least partially closed. In one embodiment, multiple sheets are rolled layers that can optionally be wrapped around a form casing (or pre-rolled inside) and then packaged with one end closed or partially closed. In another embodiment, a rod that assists in loading tobacco into the shell cavity is provided. In one embodiment, the plug takes the form of a mouthpiece.

A smoke generation product and a manufacturing method therefor, which relate to the technical field of tobaccos. The smoke generation product comprises a filter tip base body, a second connecting component, and an aroma generation portion. The filter tip base body comprises a first connecting component, and comprises a cooling portion and a filtering portion that are sequentially disposed in a smoking direction. The filtering portion and the cooling portion are connected by means of the first connecting component. A filtering passage and a cooling passage are in mutual communication. The aroma generation portion is connected to the filter tip base body by means of the second connecting portion, and the aroma generation portion is configured to release smoke by means of heating and make the smoke enter the cooling passage.

An article (1) for use in a non-combustible aerosol provision system is provided. The article comprises a rod comprising a column of aerosol-generating material (3) and a mouthpiece (2) at a first end of the column of aerosol-generating material. The column of aerosol generating material is wrapped in a wrapper (4). A component (5) is located within the wrapper at an opposite end of the column of aerosol-generating material to retain the aerosol generating material within the wrapper. A method for manufacturing an article for use in a non-combustible aerosol provision system is also disclosed.

A tobacco rod, an aerosol-generating article including the same, and an aerosol generation device used with the aerosol-generating article are provided. The tobacco rod according to some embodiments of the present disclosure may include a first filter segment, a second filter segment, and a cavity segment which is formed by the first filter segment and the second filter segment and filled with a tobacco material. Here, at least one of the first filter segment and the second filter segment may include a paper material that is grease-resistant or water-resistant. Accordingly, a problem that vapor production is decreased due to moisture absorption from components of smoke can be addressed, and a heat-resistant tobacco rod can be manufactured.

There is provided an aerosol-generating article (10) comprising an aerosol-generating substrate (12) and a filter (14) in axial alignment with the aerosol-generating substrate (12). The filter (14) comprises at least one segment of filtration material formed of one or more sheets of a fibrous paper-like material. The fibrous paper-like material comprises a combination of hydrophobic fibres and hydrophilic fibres such that the fibrous paper-like material has a water contact angle as measured in accordance with TAPPI/ANSI T 558 om-15 greater than 90 degrees. Further, the fibrous paper material has a biodegradability in aqueous medium as tested in accordance with ISO 14851 (2005) of at least 90 percent of the maximum degradation of a cellulose reference item within 56 days of testing. In addition, the hydrophobic fibres comprise hydrophobic viscose fibres.
