ABSTRACT:
A closure means for industrial waste bins of the type which can be inverted and emptied into a waste removal truck. The closure means comprises a hinged frame for connecting to the opening of a bin. The frame includes a fixed lid and a movable lid. The movable lid is displaceable along inclined support guides located on opposite marginal sections of the frame in such a manner that in an open arrangement it overlies the fixed lid and in a closed arrangement it forms a seal between the hinged frame and a marginal upper edge of the fixed lid.
