• an inner shell including a front and a rear wall connected by a pair of sidewalls and a bottom panel connecting the bottoms of all walls,
• with the inner bottom panel being smooth and flat and without depressions that might retain contents of the container and make cleaning difficult,

• said bottom inner panel sloping downwardly to the bottom of said front inner wall,
• and dispensing means at the bottom of said front walls for dispensing the contents from the container as it flows downwardly over the smooth inner bottom panel,
• whereby said container forms an integral one-piece double-wall hopper bin for liquid and for powdered material such as abrasives and the like,
• a discharge opening molded in the outer and inner front walls,
• closure means positioned over the discharge opening for opening and closing the discharge opening to dispense the contents of the hopper bin when desired,
• a slide gate,
• a pair of slide tracks mounted one on each side of the discharge opening with the slide gate slidable therein,
• handle and stop means on said gate for grasping the gate to raise and lower it and for acting as a stop when the gate is closed,
