I claim the ornamental design for a bottle topper with support legs, as shown and described.
FIG. 1 is a perspective view of the bottle topper with support legs applied to a neck of a bottle with legs of the bottle topper with support legs in a supporting position;
FIG. 2 is a view in front elevation of the bottle topper with support legs applied to a neck of a bottle with the legs in an aligned position;
FIG. 3 is a view in rear elevation of the bottle topper with support legs applied to a neck of a bottle with the legs in an aligned position;
FIG. 4 is a view in front elevation of the bottle topper with support legs;
FIG. 5 is a view in rear elevation of the bottle topper with support legs;
FIG. 6 is a view in left side elevation of the bottle topper with support legs;
FIG. 7 is a view in right side elevation of the bottle topper with support legs;
FIG. 8 is a top plan view of the bottle topper with support legs; and,
FIG. 9 is a bottom plan view of the bottle topper with support legs.
The bottle and the portions of the bottle topper with support legs shown in broken lines are shown for illustrative purposes only and do not form part of the claimed design.
