Abstract: A lid assembly for sealingly closing an interior of a container that is configured to receive a liquid substance. The lid assembly has a lid and a collapsible funnel. The lid defines an opening, a hinge, and a sealing element. The sealing element is configured for pivotal movement relative to the hinge about and between an open position and a closed position. The collapsible funnel defines a spout and is operatively coupled to the lid. The collapsible funnel is positioned in a compressed state when the sealing element of the lid is in the closed position. When the sealing element of the lid is moved from the closed position to the open position, the collapsible funnel moves from the compressed state to an expanded state. In the expanded state, the collapsible funnel extends outwardly from the outer surface of the lid relative to the central axis of the opening of the lid. Optionally, the lid assembly can be integrally formed with a body of a liquid container.
