The ornamental design for a coveredcontainer, substantially as shown and described.
FIG. 1 is a top plan view of a covered container showing my new design;
FIG. 2 is a bottom plan view thereof;
FIG. 3 is a side elevational view, which if rotated 180° results in
an identical view;
FIG. 4 is a side elevational view, taken after rotating the container
90° from its position in FIG. 3, which if rotated an additional
180° results in an identical view.
