Abstract
The fill-thru lid of the present invention threadedly engages the opening of a thermally insulated beverage server, such as a coffee pot. The opening provides a mouth for filling or emptying a liquid storage area in the beverage server. The upper surface of the lid provides a funnel opening for adding fluids to the storage area of the beverage server. The funnel opening accesses an interior chamber with a floating ball that rises to permit flow into the storage area for the fluid entering the funnel opening. When pouring from the storage area of the beverage server, the floating ball rises to block access to the passage to the funnel opening, forcing the fluid through an alternate passage leading to the integral spout opening. Further, a vent is provided that also accesses the inner chamber of the lid, resulting in the venting of air through the spout opening when fluids are being added to the storage area through the funnel opening.
