Title: Thermoformed hot drink cup

Abstract: Thermoformed cups, having elements adapted to provide a stable handle, which are nestable in a small space, the handle including a tab extending radially from the brim of the cup and a hinged flange at each side of the tab. To form the handle the flanges are turned down and are retained by shoulders of a recess in the upper surface of the cup. Weight of liquid in the cup causes the flanges to bear against the side of the cup to afford stability in addition to that resulting from retention by said shoulders.
