Abstract
Abstract A collapsible compartmented tubular carry-out tray is formed from a cut and scored blank of paperboard and comprises spaced and parallel top and bottom panels hingedly connected to spaced parallel side wall panels to define a tube. Prior to forming of the blank into a tube, the top panel is provided with apertures adapted to receive cups or the like and a single larger aperture for a larger sized article. The formation of said aperture is concomitant with the formation of partition structure extending between the top and bottom panels to give stiffness to the tube in both lateral and longitudinal directions. The partition structure includes a panel member connected to the top panel along a first fold line parallel to the longitudinal axis of the tube. The panel member has a glue flap foldably connected thereto and glued to the bottom panel. The partition structure also includes a second pair of panel members extending perpendicularly to the axis of the tube and perpendicular to the first panel member, this second pair of panel members having flaps lying along the bottom panel and including means for locking the ends of such flaps to the bottom panel. A gusset fold is provided at an end of the second pair of panel members, the gusset fold being folded from a top panel and urging the distal end of each of the second pair of panel members into the locking aperture.
