Abstract
Abstract A skeletal frame, configured in cross-section size to the lateral dimensions of an expanded collapsible bag and including bottom frame members for providing vertical support to the collapsible bag, provides structural support for the collapsible bag during fill thereof. Handles attached to the frame translate a lifting force applied thereto through the frame to the bottom and sides of the collapsible bag, regardless of the degree of fill of the collapsible bag.
