Abstract
A cover for placement on a container to allow transfer of fluid from the container to a second container comprising a lid having a skirt at its outer edge for liquid-tight attachment to the liquid filled container, a valved region centrally located on the lid, a connector located within the valve portion, and normally closed ports located within the connector. After the second container is attached to the connector the liquid-filled container with the lid attached is inverted and the lid is flexed causing the port to open and the fluid to flow from the first liquid filled container into the second container.
