Abstract
A cap for a container such as a gas tank or radiator including a valve built therein. The valve built into the cap works to equalize pressure between that inside the container and the exterior environment. The cap includes a valve subassembly joined with the body of the cap, the valve subassembly functioning to equalize the pressure by allowing ingress or egress of air.
