An integral double wall hopper adapted for use in the manufacturing of pharmaceutical tablets comprises an outer shell which forms outer walls, four legs and two runners, and an inner shell which forms inner walls, and has a frustoconical lower portion with a discharge opening molded in the bottom of the frustoconical lower portion. A detachable iris valve is positioned on the discharge opening for opening and closing the discharge opening to dispense the contents of the hopper when desired. The runners allow the tines of a forklift to pick up the hopper from the side without damaging the discharge opening or the detachable iris valve. The hopper includes a cover which has a manway formed therein, a lid for the manway, and a plurality of towers formed on the cover for protecting the manway of a lower stacked hopper and detachable iris of an upper stacked hopper from being damaged by the tines of a forklift when the hoppers are moved. The cover is hinged at one end to allow the hopper to be filled without removing the entire cover. The hopper includes a plurality of recessed thumb and finger holes formed in the walls of the outer shell to make the hopper easy to maneuver without injuring an operator\s hands.
