ABSTRACT:
The apparatus of this invention is for dispensing two liquids so that the ratio K of the flow rates of the liquids is substantially constant. The apparatus comprises two containers each having a dispensing orifice and an air vent passage having two ends, an inlet end at the outside surface of the container and an outlet end inside the container. In the preferred embodiment, the containers are geometrically proportional in shape with the dispensing or pouring orifices and vent passages all in corresponding locations. The ratio of the cross-sectional areas of the pouring orifices of the two containers is C K.sup.5/6 where C is the ratio of the flow coefficients of the two liquids to be poured. When the containers are placed in the same spatial orientation and each filled to the same proportion of fullness with different liquids and then tilted simultaneously to the same pour angle while maintaining the outlet end of the vent passage at a higher elevation than the pouring orifice for each container, the ratio of the flow rates of the liquids poured from the pouring orifices of the containers is equal to K.
