Abstract
A knob for a cooking vessel is a whistle which gives an audible signal that cooking temperature has been reached, and has a valve slide for shutting off the whistle. Supporting inside and outside knob parts incorporate halves of a resonance chamber, which makes the knob extremely simple to mold, assemble, clean, and disassemble. The valve slide rests in guides which make it impossible to assemble incorrectly, and overlaid by a knob cover.
