Abstract
A two-part container has a base and a ring. Latches along the lower part of the ring secure the ring to the base and the container is assembled in an upright position in which a flowable material is charged into the container. To dispense the material, a center outlet is provided in the base and the interior walls of the base are slanted toward the outlet. A cutoff device slides across the opening to control the flow of material through the outlet, and the cutoff device can be blocked into place. Once the container is emptied, the ring can be removed and inverted in its orientation and placed over top of the base for assembling the ring and base in a collapsed position in which the container can be returned to the distributor or distribution center. The container is stackable in both the upright and collapsed positions, and the lid sits over the top of the ring when it is assembled in the upright position and over the bottom of the ring when it is assembled in the collapsed position.
