1. A blank for a round tray comprising:

  • a bottom panel whose boundary is defined by a plurality of points of equal radii, R, from the center of said panel and uniformly distributed circumferentially about said center and by a first set of score lines in the form of arcs of circles, having radii r1, whose centers are positioned outward from said first set of score lines on radii extending from the center of said bottom panel, said score lines of said first set connecting adjacent said points;

    a plurality of intermediate panels between said points and equal in number to said points, the boundary of each said intermediate panel being defined on the bottom by one of said first set of score lines and on the top by a score line from a second set of score lines in the form of arcs of circles, having radii r2, whose centers are positioned inward from said second set of score lines on radii extending from the center of said bottom panel, the score lines of said second set of score lines connecting said adjacent points;

    r1 and r2 being defined by the following equations ##EQU2## wherein n is the number of intermediate panels,b is the elevation angle of each intermediate panel relative to the bottom panel,a is the complementary angle of b; and

    a plurality of wall panels whose boundaries are defined on the bottom by a score line of said second set of score lines.
