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.

Abstract: A metering device includes a fluid receiving chamber disposed above a container when upright, an opening in the receiving chamber for receiving fluid from the container when inverted, a vent tube connecting the ambient to the container interior, and a volume measuring chamber beneath and connected to the receiving chamber via a relatively large fluid passage. The opening has a predetermined spaced relationship above the measuring volume chamber for dumping fluid in excess of the measured volume back into the upright container and a given spaced relationship with respect to the fluid passage. A fluid deflecting shield surrounds the opening which faces away from the fluid flow when the container is uprighted. The shield, the orientation of the opening, and the given spaced relationship are arranged to divert the fluid flowing from the receiving chamber to the fluid passage around the opening.

Abstract: A spout device is connected to a liquid storage container for metering and dispensing a quantity of liquid during each successive inverting of the device and container. The spout device includes a first chamber which is in fluid communication with the stored liquid by way of a volume controlling valve mechanism to receive via gravity a given volume of the liquid determined by the valve mechanism when the container is inverted into a pouring position from an upright initial position. When the container is returned to the upright position the given volume of liquid in the first chamber flows through a connecting dump and vent conduit into a second chamber situated below the first chamber. When the container is once again tipped into the inverted pouring position the liquid in the second chamber pours through a pour spout into a suitable receiver.
