ABSTRACT:
A method of making a measuring and dispensing apparatus molded in one piece for placement in a neck of a flexible wall container is provided. The apparatus has side walls, a base wall, an open top and an upstanding central member which contains a central bore and side or lateral discharge ports for directing the flow of liquid at an angle offset from the axis of the central upstanding member. The method of making the measuring and dispensing apparatus involves injection molding utilizing upper and lower mold halves in conjunction with a center core pin and retractable orifice pins. The center core pin forms the bore present in the upstanding member of the apparatus and the orifice pins form the lateral discharge ports present in the upstanding member.
