ABSTRACT:
A slide gate assembly for closure of a discharge opening in a container for bulk material which includes a continuous flexible seal residing in an inverted U-shaped chamber around the perimeter of the discharge opening. This flexible seal has a generally rectangular cross-section with a protruding lip or flap extending inward and downward from the lower inside corner of the seal cross-section. In addition, the seal has compressible ribs in the bottom side for engagement with the upper side of the slide gate. The seal lip or flap provides a squeegee action on the upper side of the slide gate during insertion and removal of the slide gate which insures that the upper surface of the slide gate outside of the seal lip is free of material so that a positive seal between the discharge opening and the slide gate is effected when the upper surface of the slide gate is pressed against the protruding ribs on the bottom side of the seal.
