ABSTRACT:
A waste material handling container for sludges and the like having a liquid tight seal between a container door and its associated opening. The seal comprises a heavily armored resilient element and a cooperating rigid element arranged to engage the unarmored portion of the resilient sealing element through a gap in its armor. The container includes a system for selectively adjusting pressure on the door to apply a substantially uniformly distributed pressure on the resilient sealing element. The latter is formed of natural rubber having good resistance to a wide range of aggressive chemical wastes.
