The ornamental design for a bucket, as shown and described.
FIG. 1 is a front elevational view of a bucket showing my new design with the bucket body in an expanded (uncollapsed) configuration with the handle in a raised, vertical orientation;
FIG. 2 is a top plan view thereof;
FIG. 3 is a front elevational view of the bucket, but FIG. 3 shows the bucket body collapsed; and,
FIG. 4 is a front elevational view of the bucket; but FIG. 4 shows the bucket body collapsed with the handle in a lowered position.
FIGS. 1-4 show the handle in either a raised vertical orientation or in a lowered orientation; however, it is to be realized that the handle may be in any orientation between the raised vertical orientation and the lowered orientation.
The undisclosed bottom view is plain and unornamented.
