Abstract
A vent valve, and a vent valve assembly, for a liquid dispensing container, employ a vent disc having small open vent holes in cooperation with an overlying thin flexible flap that covers and closes the vent holes to limit liquid pressure on the holes when the container is upright, yet require little suction pressure to move the flap to draw liquid or vent through the holes. The vent valve can be used in a bottom cap that is attachable to the bottom open end of the container. The vent valve assembly includes such a bottom cap, a sealing member for sealing the bottom cap to the container, and a vent valve. The vent valve and/or bottom cap have an elevated vent disc and a top portion having the thin flexible flap.
