Abstract: A dispensing device for dispensing a pre-measured amount of a liquid or a powdered material from a container. The dispensing device fits inside the container and comprises a lower measuring reservoir, a discharge tube, and an upper compartment. The upper compartment couples the device to the mouth of the container and includes a pressure equalizer. The measuring reservoir is suspended inside the container by the discharge tube and upper compartment so that material can move freely around the measuring reservoir. To dispense a pre-measured amount of material, the container is inverted which causes the material to be captured by the measuring reservoir. To facilitate capturing material, the reservoir includes a number of inlet notches. The reservoir also includes an overflow tube. The function of the overflow tube is to meter the amount of material that is captured by releasing any excess which may accumulate when the container is inverted.
