A container cap for attachment to the threaded neck of a container from which a liquid is to be dispensed, which includes a base portion having a circular upper face and a depending skirt, with the skirt being threaded on an interior surface to lockingly engage the container neck. The upper face of the container has a triangular-shaped opening extending therethrough with an integral upstanding pour spout extending around the perimeter of the pour spout. The sidewalls of the pour spout converge toward one edge of the upper face and are joined by a curve of small radius to form a tip, with the other end of the sidewalls being joined by a curve of substantially larger radius. The upper ends of the sidewalls are curved outwardly and have an outwardly extending rib at the tip portion of the pour spout. The geometry of the pour spout provides a container cap from which liquid may be discharged in a smooth flow with no pulsation, with a high degree of controllability while avoiding undesirable dripping of liquid when the container is returned to an upright position.
