  • Patent number: 4243157
    Abstract: An adjustable pouring dispenser to be placed in the neck of a bottle for dispensing a controlled amount of liquid therefrom is disclosed as including a cylindrical chamber having a closed lower end with an aperture therein to control the rate of descent of a ball in the chamber when the bottle is inverted. Ports in the wall of the chamber allow liquid to flow out of the bottle through a rotatable spout until the ball cuts off flow by coming to rest on a conical seat. The ports are adjustably obstructed thereby controlling the amount of liquid dispensed, by aligning a vane on the spout with one of several indices provided on the body.
