Torch canister with fastened flame guard
A torch canister with a fuel reservoir has a neck extending from the top of the fuel reservoir defining a wick holder. The torch canister has a flame guard affixed to the neck.
1. A torch canister comprising:
a fuel reservoir having a side wall, a floor, and a top defining an interior volume for containing fuel;
a neck extending from the top of the fuel reservoir and defining a wick holder; and
a flame guard affixed to the neck of the fuel reservoir and extending over the top and laterally beyond the side wall;
wherein the neck defines a threaded connection on an exterior thereof and a non-threaded upright wall portion below the threaded connection that joins to the flame guard;
wherein the flame guard provides a cover that extends over the top and laterally beyond the side wall, and a collar centered in the cover that joins to the neck; and
wherein the collar of the flame guard is plastically deformed to grip the upright wall portion.
2. The torch canister of claim 1 , wherein the top of the fuel reservoir is frustoconical and elevates the neck above the fuel reservoir.
3. The torch canister of claim 2 , wherein the cover is frustoconical and extends downward and away from the neck.
4. The torch canister of claim 3 , wherein the cover and the top of the fuel reservoir are spaced apart.
5. The torch canister of claim 4 , further comprising a wick retained in the wick holder and having a length that extends from a location above the wick holder sufficient to allow burning of liquid fuel from the wick to the floor of the fuel reservoir.
6. The fuel container of claim 5 , further comprising a quantity of torch fuel within the fuel reservoir and a cap affixed to the threaded connection of the neck sealing the neck against fuel leaks without moving the wick.
7. The fuel container of claim 6 , wherein the top of the fuel reservoir and the floor of the fuel reservoir are both roll seamed to the side wall.
8. A torch canister comprising:
a cylindrical fuel reservoir having a top extending upwardly therefrom to a neck; and
a flame guard affixed to the neck and extending radially and downward therefrom beyond the fuel reservoir but spaced apart from the fuel reservoir top
wherein the neck defines:
a wick opening into the fuel reservoir;
a threaded fitting on an exterior top portion thereof; and
a non-threaded upright wall below the threaded fitting whereupon the flame guard is affixed; and
wherein the flame guard has a frustoconical cover extending radially downward from the neck and a collar in a center of the frustoconical cover that affixes the flame guard to the upright wall of the neck.
9. The torch canister of claim 8 , wherein the top of the fuel reservoir is frustoconical and has a steeper downward angle than a downward angle of the cover of the flame guard.
10. The torch canister of claim 9 , wherein the collar of the flame guard is plastically deformed to grip the upright wall of the neck.
11. The torch canister of claim 10 further comprising:
a wick retained in the wick holder in an operational position wherein the wick has a length that extends from a location above the wick holder sufficient to allow burning of liquid fuel from the wick to the floor of the fuel reservoir; and
a quantity of torch fuel within the fuel reservoir and a cap affixed to the threaded connection of the neck sealing the neck against fuel leaks without moving the wick from the operational position.
12. A torch canister comprising:
a fuel reservoir having a frustoconical top with a neck defining an inner wick holder, an outer threaded fitting, and an outer non-threaded upright wall below the outer threaded fitting; and
a flame guard having a frustoconical cover affixed to the non-threaded upright wall extending radially away and downward from the neck beyond the fuel reservoir and terminating in a support rim;
wherein the neck extends through the cover; and
wherein the cover and top are spaced apart.
13. The torch of claim 12 , further comprising a cap that fits onto the neck in such a manner as to seal the neck against fuel leaks while a wick remains at a position in the neck where it is exposed to allow operation of the wick to burn liquid fuel while the wick extends to a bottom floor of the fuel reservoir.
14. The torch canister of claim 13 , wherein flame guard provides a collar at a center of the frustoconical cover, the collar joining to the neck.
15. The torch canister of claim 14 , wherein the collar joins to the neck such that the fuel reservoir is suspended from the flame guard when the flame guard is supported at the support rim by a torch body.
