Abstract
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.
Claims15
A funnel comprising a hollow conical portion having a large, rimmed, mouth end and a small outlet end adapted to receive a fluent material to be dispensed, said funnel including an outlet pipe rigidly secured to the outlet end of said hollow conical portion, said outlet pipe having a longitudinal axis which is at an angle relative to the axis of symmetry of said conical portion, said funnel including a coupling member adapted to be detachably coupled to the fill opening of a container to be filled by said funnel, said coupling member having a passage therethrough receiving said outlet pipe, said funnel being rotatable relative to said coupling member about the longitudinal axis of said outlet pipe so as to permit adjustment of the filling position of said conical funnel portion relative to the container to be filled.
