Nozzle apparatus and method for dispensing powder coating material

摘要

A nozzle apparatus and method for dispensing powdered material from a container such as a cardboard shipping box. The apparatus has a shaft with a tip in the shape of a slant-cut cylinder which is manually inserted into the container through the container wall and an inner plastic lining of the container. A threaded portion on the shaft in the form of an increasing radius helix thread causes the apparatus to tighten against the wall of the container when the user manually rotates a gripping portion of the apparatus. A passageway extends from the tip to a fitting outside the container which can be connected to a vacuum source such as a powder pump to draw in the powder coating material. The fluidized powder is then carried to a spray gun for powder coating an object. A second passageway may be carried within the shaft and extend from an opening within the container to a fitting outside the container to carry a pressurized gas into the container. The container may be placed on a vibrating tilted platform to agitate the powder coating material.
