A button for a utensil lid includes a blocking member disposed against the lid and a handle part supported on the blocking member. A fastening element extends through the lid, holds the handle part and blocking member in place, and has passageways which provide communication from a chamber in the blocking member to the opposite side of the lid. The blocking element has openings providing communication between the chamber and the region outside the blocking member. A collar encircles the blocking member and is supported for limited rotation thereon, the openings in the blocking member being obstructed and free from obstruction when the collar is respectively in first and second positions relative to the blocking member.
