Abstract: A container is filled to a predetermined target mass of a free-flowing substance with the help of a device that dispenses measured doses of the substance. The dispensing device has a valve for variably adjusting the mass flow rate of the substance from a reservoir into the container. The dispensing device further includes a device to measure the elapsed time from the beginning of the filling process, a balance for determining the mass of the substance in the container, and a controller unit with a valve control module. The controller unit includes an adjusting module, where a predetermined desired mass flow rate is stored.

An adaptive filter of the controller unit determines the mass flow rate.

Abstract: A dispensing nozzle for a container with a long tapered nozzle body has a narrow tapered dispensing end and a wider base end. A passage for fluid runs from the base end to the dispensing end and through an outlet. The dispensing nozzle has a removable cap that fits over the dispensing nozzle when in the closed position which closes the dispensing nozzle's outlet with a penetrating plug located on the interior of the cap. The cap has a narrow closed end that has the penetrating plug on its interior side and the cap has a wider open end. The cap fits onto the nozzle in a tight fit when closed.
