Abstract: A protective and warming bonnet for food having two, preferably, semi-circularly curved braces 1,2 whose ends are connected to hinges (5,6). These braces may be pivoted from 0.degree. to a maximum of 180.degree. in relation to one another. A folding bellows 4 is arranged between the two braces 1,2 such that when pivoted apart, the braces 1,2 form a bellows-like dome. In one embodiment, the protective and warming bonnet has a continuous base 14 in the form of a serving platter on which the braces 1,2 rest during use. A carrying handle 13 of round-steel or a tube is hooked to the hinges 5,6 on the braces 1,2. This carrying handle 13 rests in a notch or a slot at the hinge 5,6 so that it is no longer pivotable in relation to the base while under the pressure resulting from carrying such.
