A container, that is usable for dispensing flowable materials, includes angled bottom walls which direct the flowable material to a dispensing opening. A flow cutoff device is supported, for movement between open and closed positions, in a frame assembly which defines the dispensing opening. A shield plate prevents any of the flowable material from being trapped in residual flowable material receiving areas that are adjacent the frame assembly at the outlet opening of the container. Openings are provided in an end rail of the frame assembly and also at the juncture of the end rail with spaced side rails of the frame assembly. These openings provide egress areas for any of the flowable material that might be supported by the side rails and the end rail as the cutoff device is slid along the frame assembly to the flow cutoff position.
