A safety funnel to prevent overfilling of a container being filled. The safety funnel comprises a funnel having a float supported in the funnel spout adapted to close a valve in the funnel spout when the container fill level is reached. A ring magnet is connected to the spout to attract a metallic member attached to the float and guide rod assembly into a valve seating engagement and maintain this relationship when the container is filled. The guide rod is guided within plate-like strainers and has an upper portion extending into the funnel above the spout which may be operated to open the valve to drain excess fluid in the funnel. The entire assemblage is constructed within the spout in protected relation.
