A method for the filling of a container with a potable liquid, such as fruit juice, and a filler nozzle for practicing the method. Prior methods for filling containers with potable liquids have often employed a series of nozzles, each discharging a single stream of liquid, falling under the action of gravity, vertically downward through an opening in a nozzle, each nozzle acting in cooperation and being attached to its valve. As the container is filled, both splashing and foaming of the liquid in the container, has often caused problems. According to the method and apparatus of this invention, the potable liquid to be dispensed into a container is directed to the interior surface of the container at a point above its intended fill level. By virtue of this method, foaming and splashing are minimized at each filler nozzle station. Further in accordance with the method and nozzle of this invention, a plurality of annularly spaced passageways are provided in the head of the dispensing nozzle, wherein the ratio of the length to the diameter of each of the passageways is not less than a certain minimum value. With this minimum value, found for many liquids to be four, when the valve to which the nozzle is attached is shut off, capillary attraction of the liquid remaining in the nozzle and within the passageways thereof inhibits further flow of the liquid downwardly into the container, thereby inhibiting problems caused by dripping and drooling.

A filling nozzle particularly adapted to fill containers with potable liquids containing pulp fibers therein, such as fruit juices, the containers having top seal areas and a maximum intended fill level, which is below the top seal area, the nozzle being adapted for mounting on a valve, the valve having a valve seat for closing the valve when it is desired to stop flow through the nozzle, the nozzle including an orifice head having upper and lower surfaces, wherein the orifice head has an imaginary longitudinal axis, the orifice head having a plurality of spaced-apart fluid passageways extending completely through the orifice head, each said passageway being angled such that the stream of liquid flowing therethrough strikes the container at an inside wall portion thereof at a point above said maximum intended fill level of the container, each such passageway having an uppermost part and an exit end, the uppermost part of each said passageway lying in the same plane as the upper surface of said orifice head, said plane being perpendicular to the imaginary longitudinal axis of said orifice head and wherein the spacing between the uppermost portions of said angularly disposed passageways is at least about 1/32 of an inch, whereby a land portion of about 1/32 of an inch is defined between the uppermost portions of said passageways to thereby inhibit the build-up of pulp fibers which may be in said potable liquid flowing through the nozzle, and wherein the angle between the longitudinal axes of the exit end of the passageways and said imaginary longitudinal axis of the nozzle is less than 90°, the ratio of the length of the passageways to their diameter or width having a mimimum value of four, and being such that when the valve is shut off to stop the flow of liquid through the valve and through the nozzle, capillary attraction of the liquid within the passageways is great enough to prevent further flow through the passageways, whereby closing the valve will not only stop fluid flow through the valve, but will also prevent dripping and drooling of the liquid through the passageways of the orifice head, until such time as the valve is again opened and fluid flow through the passageways recommences.
