Abstract: Dispensing of particulate matter such as powder via a gaseous stream is facilitated by placing the powder in an amorphous, manipulable pouch through which the gaseous stream flows. Squeezing and manipulating the pouch results in manipulation of the contained powder to control the amount of powder entrained in the gas stream. The pouch is supported with its outlet opening disposed generally downstream of its inlet opening in order to provide a direct, rather than a tortious, flow path through the pouch.
