a bulk bin , multi - sided container includes a bottom portion with tabs that automatically pops into position when the container is erected from the flat state . the container preferably includes a sidewall section having six panels which is attached to a bottom section having six sides with six tabs therein . two of the tabs of the bottom section are attached adhesively to cut - out portions on the bottom inside of two opposing panels of the sidewall section in such a fashion that a portion of the tabs adjacent to the attached tabs lie inside of the multi - sided container when the container is in the flat state . this structure automatically forces the remaining nonattached tabs to pop into proper alignment and position when the extreme edges of the flat sidewalls are squeezed towards each other . a top having a similar structure can be erected quickly and placed on top of the container . the container and its top can be erected in a matter of seconds . even though the remaining tabs are not physically attached to the sidewalls , nevertheless they form very satisfactory bulk bin containers which may be stacked on pallets for storage of bulk materials such as granular plastic resins , and the like .
