Abstract
Abstract A top enclosure for drinking vessels is disclosed. The enclosure enables young children to drink from the drinking vessel only when handles on opposing sides of the vessel are depressed. If only one handle is depressed, such as if the vessel drops on the floor and rolls over on one handle, then the top enclosure remains closed and fluids cannot run out of the vessel.
