Patent ID: 7231716

Claim:
A method of making a nozzle for delivering a measured quantity of viscous liquid into minute spaces comprising the steps of: a) Placing a small circular tablet of a malleable metal, containing a majority of copper, on a circular die having a cylindrical extended inner wall; b) Advancing a conically shaped mandrel against said tablet and forcing the metal to be drawn down into said die and along said cylindrical extended inner wall; c) Repeating steps a) and b) using progressively smaller-diameter, conically shaped mandrels and progressively smaller diameter circular dies having cylindrical extended inner walls until a nozzle is formed comprising: d) A flared opening defined by a horizontal perimeter and a flare extending inward from said perimeter; e) A cylindrically shaped barrel wall extending from said flare wall downward to a break point defined by a circle parallel to said flare opening and spaced apart therefrom; f) A cone shaped wall extending downward from said circular breakpoint and inward therefrom to a circular exit aperture; or; g) A cone shaped wall extending downward from said circular breakpoint and inward therefrom to a circular exit opening; and, a small-diameter exit tube extending from said circular exit opening to a circular exit aperture.
