| This invention relates to a container such as a railroad car or a truck having bottom hoppers for the discharge of loose bulk cargo which is equally usable for loose bulk cargo or prepackaged stackable cargo. The conversion of the car from a form suitable for packaged cargo to one suitable for bulk cargo is accomplished through the incorporation of self-storing slope sheets or secondary floors for use with loose cargo and the incorporation of hinged covers for use over the hoppers when the car is being used for packaged bulk cargo. The self-storing slope sheets are secured in position against an end wall or adjacent the ceiling during the hauling of packaged cargo and are against an end wall for the hauling of loose cargo. The slope sheets are moved to a position where they form a continuous sloped floor to the hopper during the unloading of the loose bulk cargo sweeping the contents to the hopper. The use of the self-storing slope sheets enables the car to be filled to its entirety when both packaged and loose cargo is being transported.
