A collapsible bulk container comprising; a cage having a generally flat and generally rectangular and rigid bottom, rigid side walls and rigid end walls carried by said bottom, said walls being collapsible from a generally upstanding position wherein a bag can be received in said cage between said walls to a knocked down position whereby said walls overlie and extend generally parallel to said bottom, and said bottom being constructed and arranged to underlie, support and carrying the weight of the contents of a bag when full and received in said cage between said upstanding side walls, and a collapsible bag of a flexible material received in said cage and which has a generally rectangular top and a generally rectangular bottom interconnected by generally rectangular side walls, when said bag is full said bottom and side walls of said bag being generally complimentary to and supported by the associated bottom and side and end walls of said cage, said bag comprises a tubular blank of flexible material having a pair of flat overlying panels adapted to form a pair of opposite side walls of the bag and a pair of folded gusset panels extending inwardly between the flat panels from the opposite edges of the flat panels and adapted to form another pair of opposite side walls of said bag, said blank having adjacent its lower end each flat panel and adjacent gusset panel connected together along lines extending diagonally inwardly from the opposite side edges of the panels toward the lower end of the tubular blank, said diagonal lines of connection terminating at their laterally inward ends in spaced apart relation laterally outwardly of the inner folded edges of the gusset panels at points spaced from the lower end of the blank, each flat panel and the adjacent gusset panel also being connected together along a line extending lengthwise of the blank from said points to termination of the diagonal line to the lower end of the blank, each flat panel and the adjacent gusset panel being severed along lines spaced laterally outwardly of and generally co-extensive in length with said lengthwise extending lines of connection to form a discharge spout at the lower end of the bag which when open has a generally rectangular cross section, the portion of the flat panels and gusset panels lying between said diagonal connection lines forming when the blank is open said bottom wall of said bag, and an access opening through said cage and constructed and arranged so that the discharge spout can be extended through said opening to discharge the contents of said bag through said discharge spout.
