ABSTRACT:
A resilient seal that may be removably mounted on the downwardly and inwardly tapering bottom portion of a hopper that defines a discharge opening, to cooperate with a gate in the form of a slide plate that normally closes the discharge opening to prevent moisture or water entering the interior of the hopper through the discharge opening when the gate is in a closed position. When the hopper has a water-tight cover mounted thereon, the resilient seal cooperates with the hopper to define a confined space within the interior thereof that is substantially moisture-proof, and one in which granular material, such as rice that is adversely affected by moisture, may be transported or stored.
