An apparatus for volumetric metering of small quantities of a product and dispensing them into containers (a) has a metering disk that revolves around a vertical axis and has metering chambers embodied as apertures disposed in groups on a pitch circle. To close the lower opening of the metering chambers, pushers with apertures are displaceably supported on the underside of the metering disk; in the filling position, they close the metering chambers, and in the evacuation position they open them. The pushers are pulled into the filling position by a spring and are pressed into the evacuation position by a controlled stop.
