Valve assembly having a base with an outlet opening for egress of liquid from a container and a vent hole for ingress of air into the container, a valve member movable between open and closed positions relative to the base for controlling passage of liquid through the outlet opening and covering the vent hole when the valve member is in the closed position, and a resiliently deformable sealing member which allows air to pass through the air hole when pressure within the container is less than pressure outside the container.

[ I claim:] [8.] A valve assembly or use with a liquid container, comprising a base, an outlet opening extending through the base for egress of liquid from the container, a tube communicating with the outlet opening and extending from the base into a lower portion of the container, a valve member movable between a close position and two open positions relative to the base for controlling passage of liquid through the outlet opening, the valve member and base including means for closing the outlet opening orifices in the valve member and the base which are aligned to provide communication between the interior of the container and the outlet opening when the valve member is in its first open position so that liquid can flow from the container through the orifices and the outlet opening when the container is in an inverted position, and means preventing communication between the orifices when the valve member is in its second open position but permitting liquid to be drawn through the tube to the outlet opening when the container is in an upright position.
