Abstract
A siphon for transferring fluid from a container to either another container at lower elevation or to a disposal area. The siphon includes a tube having an improved one way check valve which valve is inserted into the first container and, by merely shaking the tube up and down, fluid flows by gravity into the second container or disposal area. The valve includes a valve housing having a throughbore with one end of the housing coupled to the tube and the other end mating with an internal movable cup-shaped element to thereby prevent fluid flow past the element when seated in the other end of the valve housing while permitting fluid flow through the valve housing and into the tube when the element moves away from its seating position.
