Immobilized diluents in a smoking article are provided, wherein diluents can be immobilized through absorption and/or adsorption of the diluents into immobilizing materials, such as sorbents like silica gels. By immobilizing diluents, the diluents can be available for vaporization, while still being protected from migration and/or loss of the diluents in a smoking article.

A bowl for evaporation of a substance for inhalation comprises a cylindrical wall attached to a base. The bowl is made of a colorless single-crystal material selected from the group consisting of: alumina, magnesium-alumina spinel, yttrium-aluminum garnet, and cubic zirconium oxide. The bowl can have any desired color by doping the colorless single-crystal material by a transition metal. The transition metal is selected from a group consisting of: titanium, vanadium, chromium, iron and cobalt. The substance for evaporation can be positioned inside the bowl. In one embodiment, the bowl comprises a tapered cylindrical wall attached to a base. The tapered cylindrical wall can preferably be in shape of a truncated cone to which the base is attached.

Immobilized diluents in a smoking article are provided, wherein diluents can be immobilized through absorption and/or adsorption of the diluents into immobilizing materials, such as sorbents like silica gels. By immobilizing diluents, the diluents can be available for vaporization, while still being protected from migration and/or loss of the diluents in a smoking article.

A component is provided for an aerosol generating system; wherein at least a portion of the exterior of the component includes antimicrobial particles; and wherein the antimicrobial particles include monovalent copper compound particles. By providing the component in this manner, the likelihood of harmful bacteria or viruses being transmitted via the component is reduced.

An inhaler article has an inhaler body comprising a tubular side wall defining an interior and a longitudinal center axis, the interior forming a receptacle for housing an inhalable powder; a mouthpiece element extending along the longitudinal center axis from a distal end to a proximal end, the distal end of the mouthpiece element being received in the interior of the inhaler body. The mouthpiece element includes a tube extending coaxially with the inhaler body and comprising an interior surface having a first diameter; a blocker disposed at the distal end of the mouthpiece element, coaxial with the tube and having a second diameter that is greater than the first diameter; and a collector surface comprising a ring that is coaxial with and disposed proximal to the blocker, the ring defining an inner diameter and an outer diameter.

An active optical cavity laser heating medium includes an active optical cavity heating element in contact with a vaporizable substance. A light beam may be emitted into the active optical cavity heating element from a light source. The active optical cavity may then act as a gain-medium, by enhancing the laser radiation, and as a transducer, by converting the optical radiation into heat. This heat generated by the active optical cavity may then heat the vaporizable substance in an electronic vaporization device. The active optical cavity laser heating medium may also determine the temperature of the active optical cavity.

Aerosol-cooling elements for use with an apparatus for heating smokable material are disclosed. In one example, the element is a rod having a first end and a second end and comprising at least one tube within the rod, with the at least one tube extending between the first end and the second end so as to provide a through hole extending between the first end and the second end of the rod.

A cartridge for a non-burning type flavor inhaler including a flow path forming body having a shape extending along a predetermined direction to form an aerosol flow path, an outer frame having a shape extending along the predetermined direction to accommodate the flow path forming body, a reservoir that is configured to retain an aerosol source, is positioned on the periphery of the flow path forming body in a cross section orthogonal to the predetermined direction and is positioned in a gap between the flow path forming body and the outer frame and an end cap that closes the gap from the downstream side, wherein an outer edge of the end cap contacts an inner wall surface of the outer frame in the cross section orthogonal to the predetermined direction and wherein an inner edge of the end cap is positioned between the outer edge of the flow path forming body and the inner edge of the flow path forming body in the cross section orthogonal to the predetermined direction.

Aerosol-cooling elements for use with an apparatus for heating smokable material are disclosed. In one example, the element is a monolithic rod having first and second ends and has plural through holes extending between the first and second ends. Other arrangements are described.

An aerosol-generating article is provided, including: an aerosol-forming substrate; a combustible heat source; at least one layer of fibre-reinforced aerogel circumscribing at least a portion of a length of the combustible heat source; one or more airflow pathways configured such that air may be drawn along the one or more airflow pathways through the aerosol-generating article and for inhalation by a user; and one or more non-combustible, substantially air-impermeable, barriers disposed between the combustible heat source and the aerosol-forming substrate.
