A completely enclosed container has two openings or vents. One vent has an internal valve and a pouring spout attached thereto. The other vent has a spring biased safety cap which raises for filling or to vent vapors when the internal pressure exceeds some predetermined level, such as 5 p.s.i. A handle linkage is connected between the two vents so that the pouring valve opens first and the venting safety cap opens second, as the can is tipped. Suitable springs urge the valve, cap, and handle to an automatically closed position when the container is sitting at rest.
