Abstract: A shisha consumable article (101) for use with an external assembly such as a shisha assembly is described. The shisha consumable article includes a housing (110) defining a first compartment (112) and a second compartment (114) being adjacent to the first compartment. The second compartment is adjacent to, and sealed or air impermeable from, the first compartment. A combustible heat source (120) is contained within the first compartment and an aerosol-forming substrate (130) is contained within the second compartment.

Abstract: A shisha device for use with a cartridge containing an aerosol-generating substrate includes a vessel, a receptacle, and an electrical heating element. The cartridge comprises a housing surrounding the aerosol-generating substrate. The vessel defines an interior configured to contain liquid and defines an outlet in communication with the interior of the vessel. The receptacle is configured to receive the cartridge. The heating element is configured to heat the aerosol-generating substrate in the cartridge to generate an aerosol when the cartridge is received by the receptacle. Preferably, the heating element is configured to heat the tobacco substrate to an extent sufficient to generate the aerosol without combusting the aerosol-generating substrate.

Abstract: A shisha device (100) for use with a cartridge (20) containing an aerosol-generating substrate (302) includes a vessel, a receptacle, and an electrical heating element. The cartridge comprises a housing surrounding the aerosol-generating substrate. The vessel defines an interior configured to contain liquid (19) and defines an outlet in communication with the interior of the vessel. The receptacle is configured to receive the cartridge. The heating element is configured to heat the aerosol-generating substrate in the cartridge to generate an aerosol when the cartridge is received by the receptacle. The heating element is configured to heat the tobacco substrate to an extent sufficient to generate the aerosol without combusting the aerosol-generating substrate.

Abstract: 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.

Abstract: There is provided a heat source for a smoking article, including an upstream end and an opposed downstream end, and further including a combustible carbonaceous core and an integral, non-combustible, thermally insulating, peripheral layer. The core extends from the upstream end of the heat source the downstream end of the heat source. The peripheral layer extends from the upstream end of the heat source only part way along the length of the heat source and circumscribes an upstream portion of the core.

Abstract: A smoking article is provided, including a combustible heat source having opposed front and rear faces; an aerosol-forming substrate downstream of the rear face of the heat source; a first heat-conducting element including one or more radially inner layers of heat-conductive material overlying a rear portion of the combustible heat source; and a second heat-conducting element including one or more radially outer layers of heat-conductive material overlying at least a portion of the aerosol-forming substrate, such that the one or more radially outer layers of heat-conductive material do not overlie the one or more radially inner layers of heat-conductive material.

Abstract: An aerosol-generating system includes a liquid-storage portion including a housing configured to store a liquid aerosol-forming substrate. The aerosol-generating system also includes a heater configured to heat liquid aerosol-forming substrate, a vibratable element including a plurality of passages through which the heated liquid aerosol-forming substrate passes to form an aerosol, and an actuator arranged to vibrate the vibratable element to generate the aerosol.

Abstract: A combustible heat source (4) for a smoking article (2) comprises carbon and at least one ignition aid, wherein the ignition aid is present in an amount of at least 20 percent by dry weight of the combustible heat source. The combustible heat source (4) has a first portion and an opposed second portion. At least part (4b) of the combustible heat source (4) between the first portion and the second portion is wrapped in a combustion resistant wrapper (22) that is one or both of heat conducting and substantially oxygen impermeable. Upon ignition of the first portion of the combustible heat source (4), the second portion of the combustible heat source increases in temperature to a first temperature. During subsequent combustion of the combustible heat source (4), the second portion of the combustible heat source (4) maintains a second temperature lower than the first temperature.
