Paperboard bulk bin

A paperboard blank for a bulk bin, which comprises:

• a plurality of alternating, foldably connected, substantially rectangular, side panels and corner panels;
• each of said side panels having a substantially rectangular flap, foldably connected to an edge thereof;
• each of said corner panels having a four-sided, tapered flap foldably connected to an edge thereof;
• and each of said tapered flaps and said rectangular flaps being foldably connected to a triangular gusset panel disposed between them;
• the included angle in each of said gusset panels between said rectangular flaps and said tapered flaps being equal to about 180.degree. divided by the number of said gusset panels;
• the edge of each of said tapered flaps connected to said corner panels being equal to or greater in length than twice the width of said rectangular flaps times the cosine of [90.degree. minus twice the included angle in said gusset panels between said rectangular and tapered flaps];
• and
• said foldably connected side panels, corner panels, rectangular flaps, tapered flaps and gusset panels being connected along scored, fold lines.

A paperboard construction, comprising:

• a cylinder formed from a plurality of alternating, foldably connected, substantially rectangular, upstanding side panels and corner panels;
• each of said side panels having a substantially rectangular flap foldably connected to the bottom edge thereof;
• each of said corner panels having a four-sided, tapered flap foldably connected to the bottom edge thereof;
• and each of said tapered flaps and said rectangular flaps being foldably connected to a triangular gusset panel, disposed between them;
• said rectangular flaps, tapered flaps and gusset panels being positioned interiorly of said cylinder;
• the included angle in each of said gusset panels between said rectangular flaps and said tapered flaps being equal to about 180.degree. divided by the number of said gusset panels;
• and
• the edge of each of said tapered flaps connected to said corner panels being equal to or greater in length than twice the width of said rectangular flaps times the cosine of [90.degree. minus twice the included angle in said gusset panels between said rectangular and tapered flaps].
