We claim the ornamental design for a travel folder case, as shown and described.
FIG. 1 is a perspective view of the travel folder case in a closed position, in which environmental features of the outer portion of the travel folder case are shown;
FIG. 2 is a perspective view of the travel folder case in an opened position with internal flaps being flipped vertically;
FIG. 3 is a front side view thereof;
FIG. 4 is a rear side view thereof;
FIG. 5 is a right side view thereof;
FIG. 6 is a left side view thereof;
FIG. 7 is a top side view thereof;
FIG. 8 is a bottom side view thereof; and,
FIG. 9 is a perspective view of the front side of the travel folder case, in which the flaps are positioned inside the travel folder case.
Broken lines, such as those representing other internal features and the outer portion of the travel folder case, are for environmental purposes only and form no part of the claimed design. The broken lines shown on the flaps in FIGS. 2 and 7-9 represent stitching and are part of the claimed design. The hexagon openings shown on the flaps in FIGS. 8 and 9 represent a see-through mesh appearance.
