Patent ID: 8210455

Claim:
A thin-walled nozzle for delivering a measured quantity of viscous liquid comprising: a) an opening defined by a perimeter and surrounded by a cylindrically-shaped barrel wall extending from said perimeter downward to a break point defined by a circle coincident to interior of said cylindrically-shaped barrel wall spaced-apart from said opening; b) a means for connecting said cylindrically-shaped barrel wall of said thin-walled nozzle to a reservoir from which said measured quantity of viscous liquid is transferable to said thin-walled nozzle; c) a cone-shaped wall extending downward from said break point defined by a circle and then inward there from to a circular exit opening coincident to inside diameter of said cone-shaped wall; and, d) a straight, small-diameter exit tube, of uniform inside diameter, extending from said circular exit opening to a circular exit aperture of constant inside diameter for dispensing said measured quantity of viscous liquid from said thin-walled nozzle; e) wherein there is a controlled ratio of wall thickness of said small-diameter exit tube in relation to inside diameter of said small-diameter exit tube.
