  • Patent number: 5971234
    Abstract: A dust dispensing system comprised of a dip tube enclosing a much smaller outlet tube, both tubes fitted to countersunk holes in the plug base. A path for powder and air is created within the wall of a flexible container beginning at the area within the container through the longitudinal vent holes at opposite ends of the dip tube toward the inside center of the dip tube where two air/dust streams collide venting through the inward longitudinal opening of the outlet tube which is disposed at the point of convergence of the colliding streams and then the mixture continues to flow under pressure through the outlet tube and out the exit nozzle each time the container is squeezed. This action is repetitive and fully operational regardless of the device's orientation.
