ABSTRACT:
The invention is directed to an automatic locking mechanism for a dumpster container having a hinged lid. The elements of the locking mechanism comprise an L-shaped or U-shaped securing member which is attached to one or both sidewalls of the container. The securing member pivots over the lid, and is held in place by a securing mechanism. The securing mechanism fixes the L-shaped or U-shaped securing member in a position that inhibits opening of the container lid. The securing mechanism is autonatically operated by the lifting tines of a trash removal vehicle. The L-shaped or U-shaped locking member automatically swings away from the hinged lid by virtue of a counterweight during container dumping operations, and is returned to a locked configuration when the container is replaced and the lifting tines withdrawn.
