ABSTRACT:
A follower plate assembly for industrial drums includes an improved lip seal construction. The follower plate assembly has a projecting ledge to support a circumferential seal. The seal has a U-shaped cross section. The legs of the seal project radially into engagement with the container wall. The crown of the seal engages the follower plate. The ledge prevents axial movement of the seal. A circumferential band in combination with a ring or locking pins retain the seal on the follower plate.
