Abstract: A lid, for attachment to a container holding a liquid for use with a liquid spraying device, a vent duct defining a vent conduit extending through a lid body from a duct inlet end to a duct outlet end. A valve is disposed in the vent duct and is configured to permit air flow in a first direction, from the duct inlet end to the duct outlet end, while preventing liquid flow in a second direction opposite the first direction. A cap extends over the duct inlet end, the cap including a cap interior surface defining an interior air chamber, communicating with the vent conduit, and at least a first passage, communicating between the interior air chamber and a first cap inlet. A tube is coupled to the duct outlet end and has a tube outlet end fluidly communicating with an interior of the container.

Abstract: A fluid dispensing system may comprise a fluid container configured to contain paint. The fluid container may have a bottom end, an open upper rim, and a sidewall extending between the bottom end and the open upper rim. The fluid dispensing system may further comprise a lid configured to connect to the open upper rim of the fluid container, and the lid may have a connector configured to connect to a paint spray gun. The fluid dispensing system may further comprise a container holder having a cavity configured to receive the fluid container therein. The container holder may have a bottom end, an upper rim, and a sidewall extending between the bottom end and the upper rim. The fluid dispensing system may be configured to dispense the fluid by a gravity feed mechanism.
