Liquid fuel burning device

A liquid fuel burner comprising:

• a wick for burning liquid fuel drawn up therethrough by capillarity from a fuel tank,
• the wick being divided into two segments at least one of which is movable to contact and separate from the other, fuel being supplied from one segment to the other during contact and fuel supply being cut off during separation to limit burning period,
• a cap for sealingly enclosing the wick when the burner is not in use,
• means for separating the two segments upon removal of the cap from the wick, and
• an air passage communicating an interior of the fuel tank with external air at least during burning.

A disposable liquid fuel burner comprising:

• a fuel tank constituted as a sealed structure charged with a fiber material and containing, but not refillable with, liquid fuel and having a bottom wall, side walls terminating in an upper perimeter and a top wall spanning the upper perimeter of the side walls and having a portion with a substantially planar surface extending normal to the side walls with spaced first and second openings formed in and extending through the substantially planar surface portion,
• a wick having one end which is a draw-up section inserted in the fuel tank through the first opening in the top wall to contact the fiber material and draw up liquid fuel by capillarity and having another end which is a flame-producing section retained by a wick holder to project from the top of the fuel tank,
• an openable/closable closure cap movable between open and closed positions and attached to the fuel tank in both the open and closed positions, the cap having an internal space and a seal at an open end of the cap surrounding an opening leading to the internal space, the seal engaging the substantially planar surface portion of the top wall in the closed position of the cap to enclose the wick in the internal space and sealing at least the flame-producing section of the wick when the burner is not in use,
• an igniter installed near the flame-producing section of the wick for lighting the flame-producing section, and
• an air passage provided by the second opening capable of communicating an interior and exterior of the fuel tank through a portion apart from fuel passages of the wick, the second opening being closed by the cap from the exterior of the fuel tank when the cap is in the closed position.

A liquid fuel burner comprising:

• a fuel tank for holding liquid fuel and having side walls and an upper wall with a substantially planar surface portion extending normal to the side walls with spaced first and second openings formed in and extending through the substantially planar surface portion;
• a wick extending through the first opening in the upper wall portion and adapted to burn liquid fuel drawn up therethrough,
• an igniter for lighting the wick extending through the upper wall of the fuel tank,
• an air passage provided by the second opening communicating an interior of the fuel tank with external air at least during burning provided at a location apart from fuel passages of the wick,
• a cap for sealing an upper end of the fuel tank from which the wick and the igniter protrude supported for sliding motion in a straight path along a direction of wick protrusion to fit over and cover the upper end of the fuel tank from above at one end of the straight path and being laterally movable away from the upper end of the fuel tank at the other end of the straight path, and
• a seal member interposed at a sealing portion of the cap to engage the substantially planar surface portion when the cap is at said one end of the straight path.
