A mouthpiece for use in an aerosol provision system, the mouthpiece including two or more cylindrical sections circumscribed with a first, inner wrapper and a second, outer wrapper. The first, inner wrapper is a high wet strength wrapper; and the second, outer wrapper can be a porous wrapper.

The invention relates to a smoking article (1) comprising a smoking article rod portion (2) having a recess (13) and a mouthpiece (71, 91, 101) attachable to the smoking article rod portion comprising an elongate cylindrical element (20) arranged to be inserted into the recess by a user. The cylindrical element comprises an outer surface having at least one raised area (73, 103), and the at least one raised area is arranged to engage with an inner surface of the recess to provide a resistance to the movement of the cylindrical element within the recess. The at least one raised area is arranged to provide a lower resistance to movement of the cylindrical element into the recess than out of the recess.

An aerosol-generating article for producing an aerosol upon heating is provided, the article including: a rod of aerosol-generating substrate including an aerosol former, the substrate having an aerosol former content of greater than 10 percent on a dry weight basis; a hollow tubular support element positioned immediately downstream of the rod; and an aerosol-cooling element downstream of the hollow tubular support element, the aerosol-cooling element extending all the way to a downstream end of the article and including a hollow tubular segment arranged immediately downstream of the hollow tubular support element and having a transverse wall at a location between upstream and downstream ends thereof, such that the hollow tubular segment defines a first cavity upstream of the transverse wall and a second cavity downstream of the transverse wall, and the transverse wall including one or more openings establishing a fluid communication between the first and the second cavities.

A flat-shaped tobacco article configured to operate with an aerosol generating device and extending along an article axis between a mouth end and an abutting end includes a mouthpiece portion adjacent to the mouth end and a tobacco portion adjacent to the abutting end, the tobacco portion including a substrate layer extending along the article axis and forming two opposite sides, a wrapper forming an internal surface and arranged around the substrate layer so that its internal surface is in contact with one side of the substrate layer and forms a gap with the other side of the substrate layer, the gap being adapted to receive a heating blade of the aerosol generating device.

A smoking article has a burn portion and a mouth portion. The burn portion includes a smoking rod filled with a smokeable filler material formed almost exclusively of cellulose material. The mouth portion includes either a filter portion with or without an interface or a tip with an interface. The mouth end may include an orthonasal property and the interface may store an additive.

A multi-segment component for an aerosol-generating article is provided, the multi-segment component including: a combustible heat source; an aerosol-forming substrate downstream of the combustible heat source; and a wrapper circumscribing a rear portion of the combustible heat source and at least a front portion of the aerosol-forming substrate, a front portion of the combustible heat source extending beyond the wrapper so that the front portion of the combustible heat source is exposed during use; and an intumescent coating on all or part of the front portion of the combustible heat source, the intumescent coating being configured to form a heat insulating layer on the front portion of the combustible heat source in response to heating by the combustible heat source.

The present invention provides a mouthpiece or filter element (e.g., for a smoking article such as a cigarette, a tobacco heating product, a HNB product) comprising a longitudinally extending (e.g., substantially cylindrical) hollow tube of paper; a filler layer comprising paper filtering material and/or other biodegradable filtering material engaged around the hollow tube along the full (e.g., longitudinal) length of the hollow tube; and a wrapper (e.g., plugwrap) engaged around the filler layer along the full (e.g., longitudinal) length of the filler layer, wherein the hollow tube, the filler layer and the wrapper are the same length.

Disclosed is a cigarette including a tobacco rod, a supporting segment positioned at a downstream end of the tobacco rod, a cooling segment positioned at a downstream end of the supporting segment, and a mouthpiece positioned at a downstream end of the cooling segment. The cigarette according to the present embodiment may include a plurality of air channels formed along a longitudinal direction of the cigarette and the cooling segment having porosity of 50% or less.

A component for an article for use in or as an aerosol provision system, the component including a body of fibrous material and first and second objects circumferentially surrounded by said fibrous material, said first object being different from said second object. Also described is an article including the component, a method of manufacturing a component, and an apparatus configured for manufacturing a component.

Disclosed is an article for use with apparatus for heating smokable material to volatilize at least one component of the smokable material. The article comprises a sheet comprising smokable material, and heating material that is heatable by penetration with a varying magnetic field to heat the smokable material. The sheet may be a planar sheet or a rolled sheet. Also disclosed is a system, comprising the article and apparatus for heating smokable material to volatilize at least one component of the smokable material. The apparatus comprises a heating zone for receiving at least a portion of the article, and a magnetic field generator for generating a varying magnetic field to be used in heating the smokable material when the portion of the article is in the heating zone.
