ABSTRACT:
An apparatus for dispensing fine particulate matter from a flexible container includes a housing with a first open end and an opposed closed end. A nozzle is attached to the closed end extending into the housing. The nozzle has a passageway extending therethrough and a first end puncturing a wall of the container and enabling the first member to penetrate the container. A pump member is disposed transversely to the nozzle and includes a passageway having a venturi and a venturi throat disposed adjacent a first end. The second end receives a supply of fluid under pressure. A vent is attached to the cover and has one end puncturing and penetrating the wall of the container. Supply of fluid under pressure forms a pressure differential between opposite ends of the container and enables the fine particulate matter to enter the first and second passage for mixing with the fluid.
