A fluid dispensing valve for controlling the flow of a fluid from a container has a cap, a retainer, and a dispensing valve body. The cap is adapted to engage the container and includes a spout that defines a through-conduit having a top opening, a bottom opening, and an interior spout surface shaped to receive the dispensing valve body. The retainer includes at least one flow aperture and an upwardly extending plug having a plug shoulder. The dispensing valve body is bounded by an exterior surface, an interior surface, a valve perimeter, and a dispensing orifice perimeter. When the dispensing valve body is positioned on the retainer, the dispensing orifice perimeter fits securely around and seals against the upwardly extending plug; and the valve perimeter forms a sealing relationship with the interior spout surface. The retainer engages the spout to seal the dispensing valve body within the spout. |
