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 filter for a smoking article or an aerosol generating product comprising filter material and three capsules comprising additive, the capsules being disposed in sequence in a direction along a longitudinal axis of the filter.

A vapour generating article includes a main body having a first end and a second end opposite the first end, the body arranged to contain a vapour generating material; a filter having a first end arranged as a mouthpiece portion and a second end opposite the first end arranged for attachment to the first end of the main body; an air inlet portion located at the second end of the filter. The air inlet portion includes at least one aperture to allow ambient air to enter the filter. The filter includes an adjuster configured to move relative to air inlet portion to adjust the cross-sectional area of the aperture to alter an airflow through the aperture. The second end of the filter is releasably attachable to the first end of the main body.

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 inhalation device to hold an inhalant-generating component to generate an inhalant to be drawn through the device and inhaled by a user. The device has a body (10) having a first open end (11b) configured to receive an inhalant-generating component and, a second open end (11a) in fluid communication with the first end through which a user may draw inhalant from the inhalant-generating component. The body is configured to receive a flavour delivery component (63) having an organoleptic material to selectively allow or prevent addition of an organoleptic additive into an inhalant stream drawn through the device. The device includes a ventilation control mechanism (15) configured to selectively allow different amounts of ambient air into the body to mix with and dilute the inhalant stream as it is drawn through the device in use.

A smoking article comprises a tobacco rod and a filter connected to the tobacco rod. The filter comprises a first filter segment and a hollow tube segment downstream of the first filter segment. The hollow tube segment defines a cavity at the mouth end of the filter providing an unrestricted flow channel that extends from the downstream end of the first filter segment to the mouth end of the filter. The length of the hollow tube segment is at least about 25 percent of the overall filter length. Further, the smoking article comprises a ventilation zone comprising at least one circumferential row of perforations provided at a location around the first filter segment.

The present invention discloses a product for baking and atomizing, characterized by comprising a baking and atomizing segment and a filter tip segment which are wrapped by common paper, wherein a hollowed segment wrapped by the common paper is disposed between the baking and atomizing segment and the filter tip segment, the baking and atomizing segment is filled with plant fiber adsorbing an atomized object, the filter tip segment is filled with PLA, and a total length of the filter tip segment and the hollowed segment is larger than 30 mm. The product for baking and atomizing has the advantages of low cost and good environmental protection.

The present invention discloses a dual-use cigarette, comprising a suckable material segment and a filter tip segment which are wrapped by roll paper, wherein a hollowed segment surrounded by roll paper is disposed between the suckable material segment and the filter tip segment, and the roll paper of the hollowed segment is provided with a plurality of first capillary pores. The dual-use cigarette has the advantages that cold air cannot be sucked when smoking is started, and the burn of a respiratory mucosa caused by high temperature smoke can be avoided.

A smoking article comprises a tobacco rod and a filter connected to the tobacco rod. The filter comprises a first filter segment and a hollow tube segment downstream of the first filter segment. The hollow tube segment defines a cavity at the mouth end of the filter providing an unrestricted flow channel that extends from the downstream end of the first filter segment to the mouth end of the filter. The length of the hollow tube segment is at least about 25 percent of the overall filter length. Further, the smoking article comprises a ventilation zone comprising at least one circumferential row of perforations provided at a location around the first filter segment.

A backing with corrugations on a first surface. The corrugations are parallel and each has an airspace along an entire longitudinal length. A second surface of the backing includes perforations or scores oriented perpendicularly or parallel to the corrugations. The corrugations or scores are fold lines or frangible tear lines. The airspaces may also include a filter material. The second surface of the backing may be adhered to a corner of a rolling paper on the surface but opposite edge as a gum strip. The corrugations are parallel to the gum strip.
