1. A collapsible bulk bin, fabricated from a foldable material, comprising:
- a plurality of side walls, arranged in the form of a tube and connected to one another along a plurality of parallel-extending fold lines;
a plurality of bottom panels, extending from bottom edge regions of the side walls, with a fold line disposed between each bottom panel and its respective side wall, each bottom panel being pivotable between an unfolded position substantially parallel to its corresponding side wall, and a folded position substantially perpendicular to its corresponding side wall;
a plurality of connector panels, each connector panel being disposed between and emanating, along lines of weakness, from side edge regions of adjacent ones of the plurality of bottom panels;
each connector panel being pivotable between an unfolded position disposed substantially parallel to and coplanar with one of its corresponding adjacent bottom panels, to a folded position disposed in sandwiched orientation between its adjacent bottom panels, each connector panel being operably configured such that upon folding of one of its adjacent bottom panels from its unfolded position to its folded position, the connector panel prompts the other of the adjacent bottom panels from its unfolded position to its folded position, the connector panels providing slotless interconnections between adjacent bottom panels, the slotless interconnections extending from lower end regions of the fold lines which extend between adjacent ones of the side walls, so as to bridge gaps, which may otherwise be formed between adjacent ones of the bottom panels, upon articulation of the bottom panels into their folded positions, toward precluding the creation of gaps at corner regions of a bottom area of the collapsible bulk bin which may prompt failure of the collapsible bulk bin, subsequent to loading thereof.

Abstract
A collapsible bulk bin, formed from a sheet that is folded upon itself to form a tube, having a plurality of bottom panels pivotably connected to respective side walls of the bulk bin. A plurality of connector panels foldably connect adjacent ones of the bottom panels, to provide a slotless bottom configuration to provide reinforcing strength to the bottom, and bottom regions of the side walls of the bulk bin.

8. A blank for forming a collapsible bulk bin, comprising:
-
a substantially rectangular sheet fabricated from a foldable material;
a plurality of side wall panels formed therein and separated from one another by a plurality of parallel-extending lines of weakness, the side wall panels disposed at opposite ends of the sheet having free edges;
a plurality of bottom panels, extending from bottom edge regions of the side wall panels, with a fold line disposed between each bottom panel and its respective side wall panel, the bottom panels disposed at opposite ends of the sheet having free edges;
connector panels disposed between and emanating, along lines of weakness, from side edge regions of adjacent ones of the plurality of bottom panels;
the side wall panels disposed at opposite ends of the sheet being operably configured to be overlapped to form a composite side wall panel, upon folding of the sheet upon itself to form a tube;
the bottom panels disposed at opposite ends of the sheet being operably configured to be overlapped to form a composite side wall panel, upon folding of the sheet upon itself to form a tube, the connector panels providing slotless interconnections between adjacent bottom panels, the slotless interconnections extending from lower end regions of the fold lines which extend between adjacent ones of the side walls so as to bridge gaps, which may otherwise be formed between adjacent ones of the bottom panels, upon articulation of the bottom panels into their folded positions, toward precluding the creation of gaps at corner regions of a bottom area of the collapsible bulk bin which may prompt failure of the collapsible bulk bin, subsequent to loading thereof. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
