Title: Bottom unloading bulk container

Abstract: A bulk container for bottom unloading having a novel deformable bottom feature. The novel bottom feature comprises a plurality of scorelines being formed on the central portion of the bottom with the scorelines serving to weaken the bottom portion so that it deforms into a generally funnel shape from the weight of the product positioned within the container. The product is then removed from the container through an opening in the deformed bottom with the flow from the container being controlled by a slide plate if flow control is desired by the user of the container.
