Abstract
A pressure cooker handle assembly that relieves pressure in the cooker and unlocks the lid by pushing a single button twice. The button includes a tab that directly activates a pressure relief valve to release the pressure and a leg that depresses a stopbar to unlock the lid. Pressing of the button a first time releases the pressure in the cooker, but does not unlock the lid. A latch system prevents the cooker from again building pressure once the button is pressed. When the button is pressed a second time the leg depresses the stopbar to unlock the lid from the cooker.
