Abstract
An actuating device for opening and closing a whistling cap of a whistling kettle, wherein the whistling cap is rotatably mounted on the spout by means of a first pivot, comprising an actuating rod which is rotatably mounted on the whistling cap by means of a second pivot, and a spring for continuously biasing the cap into a closed position. The actuating rod has a longitudinal axis which extends in a direction at an obtuse angle .theta. with respect to a line connecting the first and second pivots in the closed position of the whistling cap. The actuating rod can move into a locked position past a dead point at which the longitudinal axis of the rod and the first and second pivots are aligned on a same line when the rod is moved to open the whistling cap.
