A pressure-release sealing cap for a reservoir includes a rotatable platform with a ramp connected to a rotatable enclosure. A movable plunger is connected to a movable pressure-release member with a guide stud and a valve. The guide stud disposed is on the ramp between first and second reference portions of the ramp, while the sealing cap is installed on the reservoir and the guide stud disposed to rotate on the ramp on rotation of the enclosure to lift the valve, to release the excess pressure while concurrently removing the sealing cap from the reservoir. The pressure-releasing member is actuated indirectly to release excess pressure from the reservoir, in a controlled and gradual manner.
