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 inhaler article includes a body extending along a longitudinal axis from a mouthpiece end to a distal end and a capsule cavity defined within the body. A mouthpiece air channel extends from the capsule cavity to the mouthpiece end. An end cap is disposed within the distal end and extends to the capsule cavity. The end cap extends from an end cap distal end to an end cap inner end. The end cap includes an air channel extending from the end cap distal end to the end cap inner end. The air channel is non-parallel with the longitudinal axis.

Abstract: A dry powder inhaler for providing pharmaceutically active particles includes a mouthpiece portion removably coupled to a distal end portion. The mouthpiece portion extends between the mouthpiece end and a first mating end. The distal end portion extends between a second mating end and the distal end. A capsule cavity is defined within the first mating end. An airflow element is disposed within the distal end portion and extends a longitudinal length to the capsule cavity. The airflow element includes an airflow channel extending the longitudinal length of the airflow channel and non-parallel with the longitudinal axis, the airflow channel directs inlet air into the capsule cavity, and a resealable membrane configured to reseal when a piercing element is withdrawn from the resealable membrane.

The air inlet region has an air inlet and an Nair 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: A smoking article includes a tobacco substrate and a wrapper disposed about the tobacco substrate. At least an inner or outer surface of the wrapper is hydrophobic via hydrophobic groups chemically bonded to the wrapper. The wrapper has a permeability of at least about 15 CORESTA units.

Abstract: A liquid tobacco composition comprises tobacco dissolved in an ionic liquid. Removal of selected tobacco constituents is aided by dissolving the tobacco in the ionic liquid. The tobacco, having selected constituents removed, may be regenerated from the liquid tobacco composition by separating the tobacco from the ionic liquid.

Abstract: A smoking article (10) incorporates a tobacco substrate including tobacco having a tobacco density of 150 mg/cm3 or less and a hardness of 60% or greater. The tobacco substrate can include a tobacco aerogel (20).

Abstract: A smoking article (10) incorporates a mouthpiece (14), the mouthpiece includes an open pore structure converted from an organic gel and a functional material dispersed in the open pore structure, such as aerogel particles (20).
