Abstract: A sealable funnel assembly is disclosed which comprises a funnel body with a stem portion and cup portion, the stem portion having a hollow bore formed therethrough. A core member is coaxially disposed within the funnel body and includes an upper handle portion and an enlarged lower sealing portion which fits sealingly inside the bore to temporarily prevent fluid flow through the funnel assembly. Motion of the handle portion of the core member upwardly or downwardly serves to either seal off the funnel assembly from fluid flow therethrough or to allow fluid flow through funnel assembly. The cup portion may have indicia inscribed thereon to aid in using the apparatus as a measuring device.
