An aerosol-generating article according to an embodiment of the disclosure includes: a tobacco rod having an outer circumferential surface surrounded by a wrapper; a filter rod having an outer circumferential surface surrounded by the wrapper, and including a segment including a structure supporting the wrapper in a transverse direction and at least one channel formed between the wrapper and the structure: and an airflow obstruction configured to obstruct an airflow of aerosol passing through the at least one channel.

An aerosol-generating article having an upstream end and a downstream end is provided, the aerosol-generating article defining a longitudinal direction between the upstream end and the downstream end, the aerosol-generating article including: an aerosol-forming substrate; a tubular element disposed downstream of the aerosol-forming substrate and extending along the longitudinal direction, the tubular element including an air inlet; and a flavour substrate disposed downstream of the air inlet, the flavour substrate including a flavour material configured to be fluid permeable when a temperature of the flavour material is equal to or greater than a permeability transition temperature of the flavour material, and being configured to be substantially fluid impermeable when the temperature of the flavour material is lower than the permeability transition temperature of the flavour material, the flavour material being a gel composition. An aerosol-generating system including the aerosol-generating article and an aerosol-generating device is also provided.

An apparatus can manufacture cigarettes of the type having a frustoconical rolled paper with a proximal end thereof and open at a distal end thereof. A smokable material can be filled within the rolled paper. The apparatus includes an elongated, retractable rod extendable through either the open distal end or the proximal end of the rolled paper. With the retractable rod extended through the open distal end of the rolled paper, the rolled paper may be filled with the smokable material by the apparatus, compacted, and the retractable rod then retracted to leave an air channel through the smokable material in the cigarette. An adhesive may be sprayed on the smokable materials proximate the air channel to maintain the coherence of the air channel.

Articles and related methods and systems for use as or as part of a non-combustible aerosol provision system including an aerosol-generating material having at least one aerosol forming material and a cylindrical body disposed downstream of the aerosol-generating material. The distance (d) between the downstream end of the aerosol-generating material and the upstream end of the cylindrical body is less than about 22 mm. A hollow tubular member can be disposed downstream of the aerosol generating material, the hollow tubular member having one or more ventilation areas,

A sidewall-punctured heated tobacco product (9), comprising a tobacco section (1) and a functional mouthpiece rod section (3). A vapor extraction section (2) is provided between the tobacco section (1) and the functional mouthpiece rod section (3). The tobacco section (1), the vapor extraction section (2), and the functional mouthpiece rod section (3) are wrapped and connected together by means of external wrapping and tipping materials. The vapor extraction section (2) is a cylinder comprising a hollow structure (2-1), and at least one sidewall through hole (2-2) communicated with the hollow structure (2-1) is formed on the sidewall of the cylinder. In use, the tobacco product (9) is inserted into a closed heating smoking set, and during vaping, vapor generated by the tobacco section (1) is mixed, after active migration, with air entering from the sidewall through hole (2-2) to form mainstream vapor. The tobacco product (9) can conveniently adjust the extraction efficiency, dilution rate, and temperature of vapor, thereby improving the organoleptic qualities of the heated tobacco product (9), and can effectively prevent cold air from passing through the tobacco section (1) during a vaping process, thus improving the heating efficiency, and effectively reducing the content of oxygen of the tobacco section (1) to achieve a heat-not-burn purpose. In addition, the tobacco product (9) is simple in structure and easy for industrial production.

An aerosol-generating article (1) comprising: a first element (10) comprising an aerosol-forming substrate (12); and a hollow tubular element (100) disposed downstream of the first element (10). The hollow tubular element (100) comprises: a peripheral portion (110) defining a hollow inner region (120) of the hollow tubular element (100); and a support element (130) formed from a sheet and extending from a first point (131) at the peripheral portion (110) across the hollow inner region (120) to a second point (132) at the peripheral portion (110). The hollow tubular element (100) has an average weight of about 10 milligrams per millimetre length or less.

An aerosol-generating article is provided for producing an inhalable aerosol when heated, the aerosol-generating article including: a hollow cylindrical rod of aerosol-generating substrate; a wrapper circumscribing the hollow cylindrical rod; and a hollow tube extending along a longitudinal axis of the hollow cylindrical rod and defining a central airflow channel of the aerosol-generating article, the hollow tube including a plurality of openings extending through a wall of the hollow tube, such that the aerosol-generating substrate in the hollow cylindrical rod is in fluid communication with the central airflow channel through the plurality of openings, and such that a ratio between a cumulative cross-sectional area of the plurality of openings and a cross-sectional area of the central airflow channel is from about 0.042 to about 0.672.
