A dispenser for fluid material comprising a cylindrical container with a metering device disposed therein. The container comprises a dispensing end and a closed end, while the metering device forms a dispensing cavity separated from a storage cavity at the dispensing end of the container and a metering cavity formed at the closed end of the container. Movement of the container to a position with the closed end disposed downwardly and then to a position with the dispensing end disposed downwardly is effective to cause fluid to flow from the storage cavity into the metering cavity and be metered in a desired quantity into the dispensing cavity. |
