Abstract
This invention teaches a dispensing container (10) whereby a predetermined quantity of powdery or granular materials can be dispensed for each pouring operation. Such container is partitioned into one volume control chamber (27) and one storage chamber (28) by a guard panel (50). Upon tilting of the container, material flows out through a metered dispensing outlet (30) until a swinging control panel (40), induced by gravity, moves downward to completely block any further outflow. The quantity to be dispensed can be changed by adjusting the opening sizes of the outlet. An additional free-flow outlet (35) provides the user an option to use this container either as a measured pourer or as a free pourer.
