ABSTRACT:
A particle sprayer includes a hollow body divided into an air compartment and a storage compartment for particulate material. The air compartment receives a piston which is manually slideable along the length of the air compartment to create air pressure within the air compartment. An air passageway provides air flow communication between the air compartment and the exterior of the sprayer. A discharge tube extends into the material in the storage compartment at one end and at the other end intersects the air passageway near a restriction in the air passageway defining a venturi opening. Depression of the piston creates increased air flow velocity past the venturi opening and the resultant low pressure area draws material up the discharge tube from the storage compartment to be dispersed in a uniform amount into the air in the air passageway and ejected from the sprayer as a spray.
