  • Publication number: 20050067436
    Abstract: A bottle for dispensing constant liquid is disclosed. Removing a retaining cap from a reservoir and loosening a ring will enable a free rotation of a spout for moving a conduit vertically at a flow regulator as grip means rotates until a top opening of the conduit is flush with a predetermined mark of scale. Fastening the ring and pressing the reservoir will direct liquid to flow upward into a cup through the tube and the conduit until liquid has reached a level higher than the top opening of the conduit. Releasing the pressing will cause liquid above the top opening of the conduit to flow back to the liquid reservoir and store liquid below the top opening of the conduit in the cup. Finally, pressing and turning the reservoir upside down will discharge liquid from the cup.
