Abstract

A drinking valve assembly includes an inner member with an aperture and an outer member with a movable drinking spout extending from an upper surface of the outer member. The inner member and the outer member of the drinking valve assembly form a channel extending from the aperture to a spout outlet. The outer member has an inner surface that contacts the inner member about the aperture to block flow along the channel with the spout in a first position, the inner surface of the outer member being displaced from the inner member in response to movement of the spout to a second position to enable flow along the channel.
