ABSTRACT:
A polygonal container having a container sides assembly and a separate container bottom assembly, which is adapted for interlocking engagement with the container sides assembly at a lower portion thereof thereby to form the container bottom. The container sides assembly is foldably formed from a unitary blank of relatively rigid but foldable material and has a plurality of generally rectangular side panels hingedly interconnected to form an enclosure defining the sides of the polygonal container. A plurality of lower edge flaps are hingedly connected to the lower edge of the rectangular side panels and are adapted for folding upwardly and inside the enclosure to interlockingly receive corresponding elements of the container bottom assembly. The container bottom assembly is also foldably formed from a unitary blank of relatively rigid but foldable material and has a plurality of generally triangular bottom panels equal in number to the side panels, a plurality of interconnecting webs each web being foldably disposed between a pair of adjacent triangular bottom panels and downwardly therefrom for disposing adjacent bottom panels in abutting relationship at two sides of the triangular bottom panels. The container bottom assembly further includes a plurality of ear members corresponding in number to the number of lower edge flaps on the container side assembly, each of which ear member is hingedly connected to the third side of a triangular bottom panel and downwardly extending therefrom for engagement with the flaps hingedly connected at the bottom portion of the container sides assembly.
