ABSTRACT:
A container consisting of a rigid outer tank having a collapsible bag liner for retaining viscous substances such as grease. A vane shape spacer assembly is disposed inside the bar and secured to the open upper end of the bag to provide a skeletal structure about which the bag can collapse as the grease is being removed to thereby insure more complete evacuation of a filled tank than has heretofore been possible.
