Abstract
A valve assembly which may be incorporated in a pump and container arrangement so as to permit the dispensing of liquid from the container when the container is in an inverted position as well as when the container is in its normal upright position. The valve assembly is primarily formed by a disc which has formed as part thereof a valve unit. The valve unit, in turn, is provided with a vent passage therethrough which is normally closed in the inverted position of the unit and a liquid passage which is normally closed in the upright position of the valve assembly. The liquid passage is opened by the weight of the liquid within the container on the ball check valve thereof when the container is inverted.
