    Abstract: A dripless liquid dispenser having an inlet for receiving liquid at dispensing pressure and one or more dispensing ports through which the liquid exits from the dispenser. Each port is provided with an individual pressure-actuated valve which opens to pass liquid to the port when liquid is supplied to the dispenser inlet at normal dispensing pressure and closes to block dripping of the liquid from the port when the supply of liquid to the dispenser is Shut off. The preferred dispensing port shutoff valve is an elastic valve sleeve surrounding the communicating passage between the port and dispenser inlet and having an exit end located immediately adjacent the port which normally assumes a constricted configuration wherein the sleeve blocks liquid flow to the port.
