ABSTRACT:
A funnel assembly which includes an interior funnel and an exterior funnel. When an interior funnel is inserted into the exterior funnel, three equally spaced raised projections prevent contact between the outer surface of the interior funnel and the inner surface of the exterior funnel. This arrangement creates air passages between the two funnels for the venting of displaced air. Consequently, the liquid being poured runs faster into a container, unaffected by the upward movement of the vented air. The interior and exterior funnels are individually, integrally formed and come together as the exterior funnel is snapped into place next to the interior funnel by three wedges protruding on the outside spout of the interior funnel. These wedges are forced against the spout of the exterior funnel and hold the two funnels equidistant to each other.
