Abstract
A torch includes a tank adapted to contain a fuel, a firebowl atop the tank defining a fill opening, and an operating device that fits over the firebowl as a snuffer. A closing device may be fitted into the fill opening. The closing device may be movable between a lowered closed position and a raised open position. The closing device defines at least one recess for receiving a portion of an operating device that moves the closing device between the open and closed positions.
