ABSTRACT:
The spigot comprises a conduit that communicates with the interior of the container to which the spigot is attached. The conduit communicates with a valve body that comprises a chamber that includes an opening that is selectably opened and closed by a valve element. The valve element may be movable into and out of engagement with a valve seat formed around the opening. The valve element may be biased to the closed position by a spring such as an elastomeric diaphragm. The elastmeric diaphragm may seal the chamber and be exposed such that depressing the diaphragm moves the valve element from the normally closed position to an open position. The valve body may be disposed such that it extends from the first conduit at an angle. The opening in the valve body communicates with a second conduit that extends from the valve body to receive the flow of fluid.
