The present invention relates to a button for gripping the lid of a culinary item. The button has a base fixed to a bonnet lid to receive a culinary article and to delimit a steam evacuation channel with the bonnet. A locking system integrates a gripping unit to the base, where the unit is rotatively mounted around the base along a rotation axis in an angular steam throttling range delimited by two extreme angular steam throttling positions, so as to block an outlet of the channel based on its position. The base and the gripping unit comprise conjugated fixation units, for allowing fixation with respect to each other by relative axial connection.
