A microwave pressure cooker including safety interlock mechanisms. A blow vent is provided in the cooker lid, and a lock bar is pivoted to the cooker lid in a position to block the blow vent when the lock bar is resting under its own weight. The free end of the lock bar includes a lock tab with a spline projecting outward. The lock tab extends through a slot at the periphery of the lid. The cooker base include a handle with a cam section ending in a lock wall. The cooker lid is placed on the base in a release position and rotated to a locking position. During this rotation the lock tab rides over the cam section and then falls adjacent the lock wall, thus sealing the blow vent. After cooking the cover is physically prevented from rotating back to the release position by the lock tab abutting the lock wall. The user must physically lift the lock bar which in turn unseals the blow vent to ensure internal pressure is released. The spline may hold the lock bar in the raised position during rotation to the released position.
