Abstract: A funnel has a float member which rises when a container is filled to warn the user to halt the pouring of a liquid. The funnel body has a conical funnel portion with three colored circles, of different colors, at separated levels on the cone. The float member, near its top, has color marks which match the color circles on the funnel cone. When the funnel nozzle (neck) is inserted into the container orifice, one of its colored circles will meet the lip of the container. The user fills the container until the same color mark on the float member reaches the top of a sleeve which guides the float member.
