1. A torch comprising: a tank defining an inside and an outside and adapted to contain a fuel; a fire vessel atop the tank opening on the outside of the tank, the fire vessel defining a fill opening to pass the fuel from the outside of the tank to the inside of the tank; a closing device fitted into the fill opening and including a wick holder and a stopper mounted around at least a portion of the wick holder; a wick in the wick holder that draws fuel from inside the tank to the fire vessel for combustion in the fire vessel outside the tank; an operating device that fits over the fire vessel as a snuffer; and at least one inwardly extending projection extending inwardly from an interior wall of the fill opening; at least one outwardly extending projection extending outwardly from the closing device; wherein the closing device has a lowered, closed position wherein the stopper prevents movement of fuel between the fire vessel and the inside of the tank, and the closing device has a raised, open position wherein the stopper allows movement of fuel between the fire vessel and the inside of the tank; wherein the closing device is rotatable such the at least one inwardly extending projection meshes with the at least one outwardly extending projection to place the closing device in a locked position preventing vertical movement of the closing device from the lowered, closed position to the raised, open position; wherein the closing device is rotatable such that the at least one outwardly extending projection is shifted rotationally with respect to the at least one inwardly extending projection to place the closing device in an unlocked position such that the closing device is movable between the lowered, closed position to the raised, open position and vice versa; wherein the closing device defines at least one recess for receiving a portion of the operating device that moves the closing device rotationally between the open and closed positions.
