  • Patent number: 4477247
    Abstract: A liquid fuel burning torch includes a container having a substantially barrel-shaped main portion which defines a chamber accommodating a liquid fuel during use. The top wall of the container has an upwardly upset threaded neck portion on which there is mounted a closing cap having a circumferential wall provided with external and internal threads, the internal threads meshing with the external threads of the neck portion. The closing member also has a transverse wall which has a central aperture for the passage of a wick therethrough. A snuffer cap having a circumferential wall provided with threads meshing with the external threads of the closing member can be fittingly mounted on the closing member so as to extinguish the flame by denying access of oxygen to the wick portion extending outwardly of the closing member. The closing member has an external flange which frictionally engages the top wall of the container around the neck portion upon tightening.
