Smoking articles and use thereof for yielding inhalation materials

摘要

The present invention describes articles, such as smoking articles, that can provide an inhalable substance in a form suitable for inhalation by a consumer. The article comprises a cartridge with an inhalable substance medium therein, control housing that includes an electrical energy source and an electrical power source, and a heating member that may be located in either the cartridge or the control housing. The control housing further may include puff-actuated current actuation components and current regulation components.

主权项

1. An article that yields an inhalable substance, the article comprising:
a substantially tubular shaped cartridge body having an engaging end, an opposing mouth end configured to allow passage of the inhalable substance to a consumer, and a wall with an inner surface that defines an interior cartridge body space; a substantially tubular shaped inhalable substance medium positioned within the cartridge body and having a wall with an inner surface and an outer surface so as to define an annular space of a specified volume between the outer surface of the inhalable substance medium wall and the inner surface of the cartridge body wall, the inhalable substance medium having a first end in proximity to the mouth end of the cartridge body and having a second end in proximity to the engaging end of the cartridge body; an electrical heating member that is operatively positioned to provide heat to at least a segment of the inhalable substance medium sufficiently to form a vapor comprising the inhalable substance, the vapor being released from the inhalable substance medium within the annular space; and a control housing having an end for receiving the engaging end of the cartridge body and including an electrical energy source that provides power to the electrical heating member such that when the cartridge body and the control housing are operatively connected, the inhalable substance medium and the electrical heating member align so as to allow for heating of at least a segment of the inhalable substance medium.
