ABSTRACT:
An on/off valve for a liquid-directing funnel having a tapered funnel outlet spout features a substantially spherical occluding element resident in the outlet spout. The diameter of the occluding element is such that the occluding element rests against the wall of the tapered spout close to a funnel outlet to prevent passage of liquid therethrough while minimizing discharge at the funnel outlet when the occluding element shuts off flow from the funnel. The occluding element's position in the outlet spout is determined by a wire-like element protruding from the occluding element out of the funnel outlet, the protruding element extending substantially parallel to the outlet spout axis and then bending to form a transverse arm which contacts a rim of a vessel being filled by the funnel whenever one wishes to start flow therefrom.
