Abstract
A multiple flavor post-mix beverage dispensing head has a nozzle, a diluent outlet in the nozzle, a plurality of discrete concentrate outlets in the nozzle, a spout under the nozzle, an outlet from the spout for discharge of beverage from the head, and the improvements of a downward facing open concavity in the center of the nozzle and bounded by a downward facing sharp edge forming the lowest part of the nozzle, a convex bottom nozzle surface extending upwardly from the concavity sharp edge, a sharp edged and squared counterbore between the convex bottom nozzle surface and a restrictor bore in each of the concentrate outlets, sharp edges on all surface intersections on the nozzle bottom surface and rounded intersections between all surfaces in the interior of the spout, an included angle between the bottom surface of the nozzle and inner surface of the spout which is divergent toward the centerline of the spout and which turns into the spout outlet, and a toroidal diluent flooding chamber between the nozzle and the spout and outside of the concentrate outlets.
