A round tray and a blank for making the tray. The tray has a bottom panel, a plurality of intermediate panels symetrically disposed about the center of the bottom panel, and a plurality of upstanding panels to form the sides of the tray. The upstanding panels may be tilted slightly outward in a conical shape to cause the diameter of the top of the tray to be slightly larger than the diameter of the bottom of the tray. Alternate ones of the upstanding panels are positioned on the inside of the tray, and their adjacent upstanding panels have circumferentially extending glue flaps which overlap the inner panels. The total number of upstanding panels and the total number of intermediate panels are equal, with each upstanding panel being foldable relative to an intermediate panel immediately below it about a first set of fold or score lines. The intermediate panels, in turn, are folded upward from the horizontal about a second set of fold or score lines. The boundaries of the intermediate panels are each formed by a score line from the first set and a score line from the second set of score lines, the first and second score lines of a particular panel coming together at points on the edges of the intermediate panel and on the edges of the upstanding panels. A point of intersection of the first and second score lines which define the edges of an intermediate panel is also the point of intersection for the first and second score lines of the next adjacent intermediate panel. Those points of intersection are formed on a circle about the center of the base panel but elevated slightly above the plane of the base panel.
