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.

A lid for attachment to a container holding a liquid for use with a liquid spraying device, the lid comprising:
- a lid body defining an exterior surface and an interior surface;
- an adapter extending from the exterior surface of the lid body and configured to releasably couple with the liquid spraying device, the adapter defining a liquid conduit extending through the lid body;
- a vent duct defining an vent conduit extending through the lid body, the vent duct including a duct inlet end extending from the exterior surface of the lid body and a duct outlet end extending from the interior surface of the lid body;
- a valve disposed in the vent duct and 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 extending 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;
- and
- a tube coupled to the duct outlet end.

- a container;
- and
- a lid releasably coupled to the container, the lid including:
- a lid body defining an exterior surface and an interior surface;
- an adapter extending from the exterior surface of the lid body and configured to releasably couple with the liquid spraying device, the adapter defining a liquid conduit extending through the lid body;
- a vent duct defining an vent conduit extending through the lid body, the vent duct including a duct inlet end extending from the exterior surface of the lid body and a duct outlet end extending from the interior surface of the lid body;
- a valve disposed in the vent duct and 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 extending 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;
- and
- a tube coupled to the duct outlet end.
