Abstract:
1. An air valve for use with a pouring device for the dosing of liquid from a container, the air valve comprising: (a) an air valve channel and an air vent tube, the air vent tube comprising an air flow inlet opening at one end; (b) a weighted magnetic component comprising a magnet portion and a weighted portion; the weighted magnetic component positioned in the air valve channel; (c) a metal ball positioned at the air inlet opening of the air vent tube; wherein when the air valve is in an upright position, a magnetic force between the metal ball and the weighted magnetic component causes the metal ball to close the air inlet, and wherein when the air valve is tilted to a pouring position, the weighted magnetic component slides away from the metal ball, allowing air to flow into the air inlet.
