Abstract
Embodiments of the present invention provide a pouring device for a container for the dosing of liquid. The pouring device has an improved air valve system that works via cooperation between a weighted magnetic component and a metal ball in order to control opening and closing of the air valve inlet.
Claims14
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.

A pouring device for a container for the dosing of liquid, the pouring device comprising:
- (a) a spout housing configured to seal an opening of the container;
- (b) a conduit extending through the spout housing for liquid passage through the housing;
- (c) an electrically operated valve disposed within the spout housing for selectively clamping the conduit so that a registerable amount of liquid can be dosed;
- and
- (d) an air valve configured to be secured to the spout housing, the air valve comprising
- (i) an air valve channel and an air vent tube, the air vent tube comprising an air flow inlet opening at one end;
- (ii) a weighted magnetic component comprising a magnet portion and a weighted portion;
- the weighted magnetic component positioned in the air valve channel;
- (iii) 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.
