Abstract
Abstract A device for delivering flavor utilizing a flavor carrier in powdered form. A preferred embodiment of the system may resemble a conventional cigarette, and includes an overwrap defining a path of airflow through the device, a chamber containing particulate matter, and a means for entraining the particulate matter in the airflow. The overwrap may be a tube, resembling a conventional cigarette in appearance, feel, and draft. A means for entraining the particulate matter may be an intake flow limiter having a passage therein which causes a thin stream of high-velocity air to impinge upon the particulate matter, entraining it in the airflow. Alternately, the entraining means may be a series of baffles or similar components which produce a turbulent airflow, thus entraining the particulate matter. Output means are also provided for eliminating stoppages and for delivering the airflow, with particulate matter entrained therein, to the user.
