Abstract
A dual ball valve straw lid assembly for a closed container is provided. The dual ball valve straw lid assembly includes one or more of a lid, a liquid ball, a vent ball, and a tube. The lid includes a top and a bottom, and the bottom is configured to attach to the closed container. Each of the liquid and vent balls are pivotably coupled to the lid top and each configured to rotate between open and closed positions. The vent ball is configured to rotate in response to the liquid ball rotates. The tube extends from the lid bottom to within the closed container, and allows liquid in the closed container to be accessed by suction force applied to the liquid ball in the open position. When open, the vent ball allows air to pass between outside and inside the closed container when in the open position.
