Abstract: A metering device for liquids with a container, which has at least one elastically deformable wall section, and with a metering vessel. The container has an outlet with a withdrawal opening which, corresponding to the liquid to be measured out, is so narrow, that liquid emerges only when the deformable wall section is indented. The metering vessel can be connected detachably with the container, so that it surrounds the withdrawal opening during metering process. While the liquid is being measured out and with the container and the metering vessel in the inverted position, there is a liquid-tight connection between the metering vessel and the container. The very narrow withdrawal opening enables liquid to emerge when the derormable wall section of the container is indented, but prevents any flow of liquid after the metering process is completed and the metering vessel is removed.
