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.

A blank for a container of fiberboard or the like comprising a tubular body of octagonal horizontal cross-section having eight upstanding wall panels connected together at vertical corners, and a bottom flap arrangement on the body including two inwardly extending horizontally disposed flaps connected at their outer edges to respective opposed wall panels and having their inner edges meeting, said flaps together being of the same cross-sectional area and contour as the tubular body of the container; said blank consisting of a flat sheet of fiberboard material cut, slit and scored to provide eight wall-forming panels including two side wall panels, two end wall panels and four connecting panels, connected hingedly together at laterally spaced, vertically extending score lines; and a bottom flap arrangement hinged on the lower side of said sheet along a common horizontal score line including two form flaps which are connected to said side wall panels, each of said form flaps being of hexagonal form and one-half the area and contour of the octagonal horizontal cross-section of the container body and having an edge hinged to its respective side wall panel and co-extensive therewith, an opposed edge of a length corresponding to the spacing of the end walls in the body of the container and space from the hinged edge a distance which is one-half the spacing of the side walls, in the body of the container and connecting end edges to engage and position the said end and connecting panels, each of said connecting end edges including a straight edge at a right angle to said outer edge of a length equal to one-half the width of an end panel and another edge extending angularly therefrom to said horizontal score line at the adjacent vertical score line; said two side panels having a connecting panel hinged respectively to one edge with an end panel hinged intermediate the two connecting panels at vertical score lines, one of the remaining connecting panels having one edge hinged at a vertical score line to the adjacent side panel to be outermost, the other connecting panel being hinged at vertical score lines intermediate the other end panel and the adjacent side panel so that the end panel is outermost, an attaching flange hinged at a vertical score line to the outermost connecting panel; the bottom flap arrangement consisting of the said form flaps hinged at the horizontal score line to the side panels, an end flap hinged at the horizontal score line to the intermediate end panel, a partial end flap hinged at the horizontal score line to said outermost end panel, and a partial end flap hinged at the horizontal score line to said attaching flange, said intermediate end flap having opposed angled edges extending outwardly from the horizontal hinge score line at adjacent vertical score lines and perpendicularly to the respective angled edges of the adjacent form flaps to provide triangular flaps therebetween which are hinged at the horizontal score line to the adjacent connecting panels, said outermost end flap having one such angular edge perpendicular to the adjacent angled edge of the form flap forming a triangular flap on the adjacent connecting panel, said partial end flap hinged to said attaching flange at said horizontal score line also having an angled edge extending from the adjacent vertical hinge score line and at a right angle to the angled edge of the adjacent form flap to produce a triangular flap hinged at the horizontal score line on the adjacent outermost connecting panel.
