I claim the ornamental design for a microwave tray, as shown and described.
FIG. 1 is a top perspective view of a microwave tray, showing my new design.
FIG. 2 is a top plan view of the microwave tray.
FIG. 3 is a front view of the microwave tray.
FIG. 4 is a left side view of the microwave tray, the right side view being a mirror image.
FIG. 5 is a back side view of the microwave tray.
FIG. 6 is a bottom view of the microwave tray; and,
FIG. 7 is a cross-sectional view of the microwave tray, taken along lines 7-7 in FIG. 2.
The sectional view of FIG. 7 is intended to illustrate the nature the shape of ribs formed in the tray. Cross-hatching used to indicate internal portions of the tray in FIG. 7 is not intended to convey any particular material, and the construction of the internal portion of the tray forms no part of the claimed invention.
