Abstract
A dosing spout for mounting on a container has a liquid outlet valve which, at placing of the spout in an electric field, can be actuated by the field for opening of outflow of liquid directly from the container and out through the mouth of the spout, and an air inlet valve which can let air from the surroundings directly into the container as compensation for the quantity of liquid flowing out. The armature of the liquid outlet valve and the armature of the air inlet valve are arranged consecutively in their longitudinal direction of displacement.
