Abstract
A fluid dispensing valve for a liquid container having a pouring spout is formed by an inner sleeve axially connected to the spout of a liquid container. The other end of the inner sleeve is closed and provided with wall outlet ports. An outer sleeve slidably surrounds the closed end portion of the inner sleeve for covering and uncovering the inner sleeve wall ports. The outwardly flared end of a funnel-type tube secured to the periphery of the outer sleeve projects beyond the closed end of the inner sleeve for entering a port of a receiving vessel at its other end portion. The valve is opened by axial force applied to the inner sleeve opposite its closed end which moves relative to the outer sleeve and uncovers the wall ports. Releasing the axial pressure on the inner sleeve allows a spring interposed between a shoulder or the inner sleeve and adjacent end of the outer sleeve to bias the latter toward and cover the inner sleeve ports.
