A funnel device for filling containers having either vertically or otherwise oriented filling inlets with fluent material. The device is adapted when in use to be supported by a given container's filling inlet, and is orientable relative to such inlet so as to be capable of receiving and conducting fluent material to such container while a user has free use of both hands. To increase filling speed, the device is provided with a novel venting system which is designed to rapidly vent a large volume of air or gas in a safe manner from a container being filled with the device. Part of the venting system may also be manipulated to form a siphon which can be used to drain excess material from the funnel device in the event the container is overfilled.
