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.

[ What is claimed is:] [1.] A nozzle apparatus for dispensing powdered material from a container, comprising:a shaft having a tip portion and a securing portion;a first fitting; anda first passageway extending from said tip portion to said first fitting; wherein:said tip portion is adapted to puncture a wall of the container and extend into the container;said apparatus is adapted to be positioned to cause said securing portion to engage said container to secure said apparatus therein; andsaid first fitting is adapted to be coupled to a conveying means to cause said powdered material to be transported through said first passageway from said tip portion to said first fitting;a second passageway which is carried within said shaft, at least in part, and extends into said container, at least in part, when said apparatus is secured in said container; anda second fitting which is fluidly coupled to said second passageway, and which is adapted to be coupled to a pressurized gas source to cause a pressurized gas to be transported into said container via said second passageway. [19.] A method for dispensing powdered material from a container, comprising the steps of:providing a nozzle having a shaft with a tip portion and a securing portion, and a first passageway extending through said nozzle;puncturing a wall of said container using said tip portion;inserting said tip portion into said container, at least in part; andpositioning said nozzle to cause said securing portion to engage said container to secure said nozzle therein; wherein:said nozzle is adapted to be coupled to a conveying means to cause said powdered material to be transported through said first passageway from said tip portion to said conveying means; andsaid nozzle includes a second passageway which is carried within said shaft, at least in part, and extends into said container, at least in part, when said nozzle is secured in said container, said method comprising the further step of:coupling a pressurized gas source to said second passageway to cause pressurized gas to be transported into said container.
