Abstract
A cover for closing a divided chemical dispensing container or hopper mounted on agricultural chemical-dispensing equipment. The cover closes the top of the hopper and includes a shim that seats on the divider that divides the interior of the hopper into two compartments of approximately equal size. The hopper cover is removably mounted on the top of the hopper and engages the slotted divider shim seated on the divider, to enclose the granular chemical contents of the hopper. In a preferred embodiment the hopper cover is characterized by a conventional first opening which communicates with one of the hopper compartments designed to contain a toxic chemical such as a granular insecticide. A hinged cover opens on a raised cover lip extending from the hopper cover to access a second cover opening that communicates with the opposite compartment, typically containing a granular, non-toxic fungicide. The hopper cover is fitted with a perimeter seal for sealing the perimeter of the cover on the hopper and with a divider seal for sealing the divider shim and isolating the toxic granules from the non-toxic granules inside the hopper when the hopper cover is placed on the hopper.
