Claim:
A bulk material cargo container liner system for disposition within a bulk material cargo container, comprising: a bulk material cargo container liner, for disposition within a bulk material cargo container, for containing bulk cargo material, and having a substantially rectangular parallelepiped structure when erected whereby said bulk material cargo container liner comprises a front wall surface portion, a pair of side wall surface portions, a top wall surface portion, a bottom wall surface portion, a rear wall surface portion, and a longitudinal axial extent as defined along a longitudinal axis extending between said rear wall surface portion and said front wall surface portion; at least one vacuum discharge tube member, for discharging the bulk cargo material which is disposed within said bulk material cargo container liner, disposed internally within said bulk material cargo container liner and having a predetermined longitudinal axial extent so as to extend longitudinally rearwardly from a forward internal position within the vicinity of said front wall surface portion of said bulk material cargo container liner toward a bulk material discharge port which is defined within said rear wall surface portion of said bulk material cargo container liner at an elevational level located above said bottom wall surface portion of said bulk material cargo container liner; and at least one inflatable air bag component, operatively associated with said bulk material cargo container liner for causing the bulk cargo material, disposed within said bulk material cargo container liner, to undergo fluid flow transversely, with respect to said longitudinal axis and said longitudinal axial extent of said bulk material cargo container liner, toward said at least one longitudinally oriented vacuum discharge tube member disposed within said bulk material cargo container liner when said at least one inflatable air bag component is inflated from a relatively deflated state to a relatively inflated state so as to facilitate the evacuation of the bulk cargo material from the interior of said bulk material cargo container liner without requiring the tilting of said bulk material cargo container liner.
