ABSTRACT:
A container of fiberboard or similar material which is supplied in flat knocked-down condition but when set up will be of multi-sided polygonal tubular form to give it increased stacking strength. A bottom flap arrangement includes at least two hinged flaps which, when folded with their inner free edges meeting, provide a form of the complete area and contour of the tubular container body being set up and will guide the side walls thereof into that size and contour as they are positioned around the remaining unhinged edges of such form flaps.
