Abstract: An inhaler article includes a body extending along a longitudinal axis from a mouthpiece end to a distal end with an endpiece element at the distal end. A capsule cavity is defined within the body and extends along the longitudinal axis a cavity length. The capsule cavity includes a helical feature on or in an inner surface of the capsule cavity. The helical feature extends along the cavity length. An air inlet region is between the endpiece element and the capsule cavity. The air inlet region has an air inlet and an air passageway extending from the air inlet to the capsule cavity. A porous element defines a downstream end of the capsule cavity. A mouthpiece air channel extends from the capsule cavity, through the porous element to the mouthpiece end.

Abstract: An aerosol-generating article including an aerosol-forming substrate is provided, the aerosol-forming substrate including a sheet including: a fibrous material; one or more nicotine salts; and a binder, the sheet having a binder content of at least 1% by weight on a dry weight basis, the aerosol-forming substrate further including one or more aerosol formers, and the aerosol-forming substrate has an aerosol former content of at least 10 percent by weight on a dry weight basis.

Abstract: An electrically heated smoking system for receiving an aerosol forming substrate includes a heater for heating the substrate to form the aerosol. The heater includes a heating element. The electrically heated smoking system and the heating element are arranged such that, when the aerosol forming substrate is received in the electrically heated smoking system, the heating element extends a distance only partially along the length of the aerosol forming-substrate, and the heating element is positioned towards the downstream end of the aerosol forming substrate.

Abstract: A sheet is provided, including a fibrous material, one or more nicotine salts, and a binder, at least about 20% by weight of the one or more nicotine salts being monoprotic.

Abstract: An aerosol-generating system may include an electrical power supply, an electrical heater connected to the electrical power supply, and a substrate container. The substrate container may define a blind cavity containing an aerosol-forming substrate in the form of a gel that is a solid at room temperature. The electrical heater is external to the substrate container and configured to heat the substrate container to generate a vapor without contacting the aerosol-forming substrate. As result, the possibility of unwanted materials building up on the electrical heater can be reduced, thereby providing a more reliable and consistent performance.
