Abstract: A device for pouring and measuring a volume of fluid from a container threaded to the device includes a liquid storage chamber disposed above the container when upright. An opening in the storage chamber receives fluid from the container when inverted. A vent tube connects the ambient to the container interior. A volume measuring chamber is disposed beneath and connected to the storage chamber via a fluid passage so that fluid in the storage chamber pours into the measuring chamber through the passage when the container is upright. The opening in the storage chamber connected to the container interior has a predetermined spaced relationship above the measuring volume chamber for dumping liquid in excess of the measured volume back into the upright container. A pour chamber receives the measured volume when the container is inverted for preventing the measured volume fluid from returning to the storage chamber through the fluid passage.
