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.
Claims12
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.

A torch comprising:
- a tank defining a fill hole on a top surface thereof;
- a wick opening in the top of the tank spaced apart from, and non-coaxial to, the fill hole and containing a wick;
- and
- a closing device selectively rotatable around the wick opening;
- wherein the wick opening forms an axle for the selective rotation of the closing device and a point of rotation of the axle is proximate center of the wick opening;
- wherein the closing device is movable while in contact with the top surface of the tank between an open position and a closed position;
- and
- wherein the closing device exposes the fill hole when in the open position and the closing device covers the fill hole when in the closed position.

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 holder situated at least partially within the fill opening;
- 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 provides at least one longitudinal projection that descends into the fire vessel when the operating device is used 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 at least one inwardly extending projection meshes with the at least one outwardly extending projection to selectively retain the closing device in a closed position by preventing vertical movement between the at least one inwardly extending projection and the at least one outwardly extending projection;
- wherein the at least one outwardly extending projection can be shifted rotationally with respect to the at least one inwardly extending projection such that the inwardly extending projection does not inhibit elevation of the outwardly extending projection to move the closing device into an open position;
- wherein the closing device defines at least one recess that receives the at least one longitudinal projection from the operating device allowing the operating device to impart rotational movement to the closing device to move the closing device from the closed position to the open position.
