I claim the ornamental design for a fuel burner container, as shown and described.
FIG. 1 is a perspective view of a fuel burner container, showing my new design as seen in-use with a fuel burner and cap;
FIG. 2 is a perspective view thereof, illustrated without the fuel burner and cap;
FIG. 3 is a front elevational view of FIG. 2;
FIG. 4 is a rear elevational view of FIG. 2;
FIG. 5 is a left-side elevational view of FIG. 2, the right-side elevational view being a mirror image thereof;
FIG. 6 is a top plan view of FIG. 2; and,
FIG. 7 is a bottom plan view of FIG. 2.
The broken lines showing a fuel burner and cap in FIG. 1 and bottom features in FIGS. 6 and 7 depict environmental matter and form no part of the claimed design.
