ABSTRACT:
A dirt and bacteria tight connection between a container for chemicals and the suction pipe of a metering pump is disclosed, which may in particular be used for the treatment of drinking water. In this way it is achieved that only degerminated air may enter the interior of the container when sucking metering fluid from the container.
