Patent abstract

A mechanism to check fluid flow from a tube or spigot when it is disconnected from a downstream conduit is provided. The mechanism includes a duckbill check valve that has its bills pointed in the upstream direction. To keep the bills apart for the fluid flow to continue, the downstream conduit has to be inserted against the underside of the bills. Once the downstream conduit separates from the valve, the valve closes itself.
