ABSTRACT:
A funnel assembly is provided for transferring material between two containers. The funnel assembly includes a funnel forming a reservoir and a spout of substantially circular cross-section that tapers along a longitudinal axis between an inlet end joined to the funnel and a distal outlet end. The spout includes an inside surface. The funnel assembly also includes a substantially spherical occluding element disposed in the spout. The occluding element has a periphery larger than the outlet end of the spout and smaller than the inlet end. The occluding element includes a resiliently flexible sealing member extending circumferentially therearound for selectively engaging and conforming to the inside surface of the spout at any of a plurality of angular displacements of the occluding element to establish an impervious seal within the spout between the inlet and outlet ends as a result of gravity and material weight acting upon the occluding element.
