Further, the tobacco rod (12) is circumscribed by a wrapper (13) having an air permeability of less than about 20 Coresta units, the wrapper being made of a transparent regenerated cellulose film, or cellophane.

A non-combustion-heating-type stick comprising: a substrate that includes an aerosol source; a cooling portion that produces an aerosol by cooling a vapor produced by heating the substrate; and a filter portion that is disposed in an area through which the aerosol passes, wherein at least one of the substrate, the cooling portion, and the filter portion contains a porous adsorbent.

A method of manufacturing a compressed rod of web material for the filter rod of an aerosol-generating article, comprising: supplying a feed of web material from a supply apparatus; drawing the web material through a filter rod manufacturing apparatus; introducing a curved ridge into the central portion of the width wise cross-section of the web material as it approaches contact with the interior of a folding funnel, by drawing the web material across a forming surface of a former that contacts a central portion of the web material, in which the forming surface deflects the central portion of the web material from a line extending between where the web material leaves the supply apparatus and the center of an outlet of the folding funnel; and folding the web material in the folding funnel to form a compressed rod of web material.

An aerosol-generating article is provided, including: a rod of aerosol-generating substrate; and a ventilation zone including perforations and being arranged downstream of the rod, the perforations being arranged in a peripheral wall of the ventilation zone, each perforation having a central axis, the aerosol-generating article having a central axis, a smallest distance between the central axis of each perforation and the central axis of the aerosol-generating article being between 3% and 15% of an outer diameter of the aerosol-generating article, a thickness of the peripheral wall of the ventilation zone being between 0.1 millimeter and 2.5 millimeters, and the aerosol-generating article having a ventilation level of at least 20%. An aerosol-generating system including an aerosol-generating device having a cavity configured to receive the aerosol-generating article is also provided. A method for manufacturing an aerosol-generating article is also provided.

A sheath for a smoking article, such as a filter cigarette, including an exterior sheath (5) that provides a ventilation structure which has a reduced possibility of occlusion, and which also prevents a reduction in filter efficacy when the strength of the draw on the smoking article by the consumer is increased, for example in order to overcome the effects of dilution of the smoke flow with ambient air. The sheath may be manufactured as an independent entity and then fitted to prefabricated smoking articles, or alternatively may be constructed as an integral part of the smoking article.

An article for use with a non-combustible aerosol provision device including a mouth end segment to be received in the mouth of a user; an aerosol-generating material configured to generate an aerosol when the article is received in the device and a user draws on the mouth end segment, and a tubular cooling segment having a longitudinal axis and being located between the aerosol-generating material and the mouth end segment through which the aerosol flows towards the mouth end segment. The tubular cooling segment includes a ventilation region through which air is drawn into the tubular cooling segment and the ventilation region is configured such that a swirling flow is generated by air entering the tubular cooling segment through the ventilation region.

Filter for a smoking product, the filter including a first filter segment and a second filter segment, wherein the first filter segment includes a component that is given off into a smoke stream passing through a filter outlet opening, and the second filter segment includes a sorption means that absorbs a component from a smoke stream passing through the filter inlet opening.

A smoking article (10, 30, 40, 50, 70) with variable ventilation comprises a mouthpiece (12) circumscribed by a first wrapper (24) and a second wrapper (25). The first wrapper (24) and the second wrapper (25) are substantially air impermeable and are movable relative to one another between a low ventilation configuration and a high ventilation configuration. The mouthpiece (12) comprises a first airflow pathway (18, 19) through the first wrapper (24) or the second wrapper (25) and a second airflow pathway (26) through the first wrapper (24) or the second wrapper (25). In the low ventilation configuration airflow into the mouthpiece (12) through the first airflow pathway (18, 19) is restricted and airflow into the mouthpiece (12) through the second airflow pathway (26) is substantially unrestricted. In the high ventilation configuration airflow into the mouthpiece (12) through the first airflow pathway (18, 19) and the second airflow pathway (26) is substantially unrestricted.

Provided is a smoking article that allows easy inhaling of a powder at a smoker's own timing, and can suppress powder spill at an unintentional timing such as during production or shipment. The smoking article includes: a tobacco rod containing tobacco; and a filter connected to an end part of the tobacco rod through a tipping paper. The filter includes a powder-containing substance that is a lump of a crude powder containing at least one of a gustatory component and a flavor component, and turns into powder when external force is applied thereon, a cavity in which the powder-containing substance is placed, and a flow path that connects the cavity and a mouthpiece end, allows passage of the powder, and has a smaller inner diameter than an outer diameter of the powder-containing substance.

A tube (10) for temporary affixment to a mouthpiece of a smoking article (80), the tube (10) comprising an open upstream end, an open downstream end, an outer surface, and an inner surface defining a lumen for receiving the mouthpiece of the smoking article, the lumen extending from the open upstream end to the open downstream end; the tube further comprising a first ventilation zone (50) for providing ventilation into the lumen of the tube, the first ventilation zone comprising a first line of perforation holes (52) circumscribing the tube at a location at least 10 mm from the open downstream end of the tube.
