The container is formed preferably from three telescoping sleeves, the inner sleeve having at least two sets of adjacent walls with the center wall of each set being provided with a wide flap that extends beyond the sides of the center wall and is formed with a stepped lateral edge on each of its sides. These flaps being foldable into a position substantially perpendicular to the axis of the sleeve and the steps cooperate with edges of walls adjacent the sets to hold the sleeve in its desired cross sectional shape. A second sleeve surrounds the first sleeve and has alternating long and short side wall with long side walls in face to face relationship with the steps or other edges on the flaps. Preferably, a substantially rectangular cross section sleeve surrounds the two inner sleeves and the inner periphery of the rectangular cross section sleeve at its corresponding ends will have a width substantially equal to the width of the wide flaps.
