ABSTRACT:
A resilient closure to be received on a container for a liquid. The closure has a raised periphery that defines a channel to engage on the container to form a seal around the container. There is a valve in the surface of the closure adjacent the raised periphery. The valve is movable between a closed and an open position but tends to remain closed in the absence of an external force. A lever is formed integrally with the closure and is raised above the surface. The lever ends adjacent the valve and the arrangement is such that downward pressure applied to the lever opens the valve to allow liquids to pass from the container. The release of the lever allows the valve to return to the closed position. The valve comprises a slit in the surface of the closure starting at and extending away from an edge of the lever.
