Abstract: This invention relates to a liquid dosing device for locating on a container. The device has a chamber with an aperture therein to allow liquid out the chamber. A spout extends through a wall of the chamber and has a first end located toward the top of the chamber and a second end extending beyond the wall of the chamber for locating inside the container. The device also has a valve arrangement which comprises a cap and a holding structure to move the cap between a storage position whereby the cap is held in sealing contact with the first end of the spout and an operative condition whereby the cap is held off the first end of the spout to allow liquid exiting the first end of the spout into the chamber.
