ABSTRACT:
A pistol-shaped powder delivery device consolidates propellant pulse creation, powder storage, powder aerosolization and aerolsolized powdered delivery in a single device while providing dose, pattern and coverage control of the output spray. The single-hand-held, single-hand-operated device includes a housing having a handle portion that is selectively collapsed to generate a propellant pulse that is conveyed into and through powder stored in a reservoir mounted at an upward angle to the horizontal in a receptacle provided in the housing. Powder in the reservoir is caused to be aerosolized by the propellant pulse whereupon aerosolized powder exits the reservoir through an open end of, and elongate slots provided in the sidewall of, an elongate hollow member extending from an outlet in the receptacle through the stored powdered material into a head space in the reservoir. The outlet is connected a barrel portion for output of the aerosolized powder spray.
