<p>A commercial trash bin is provided with locking arrangements which restrict the use of the trash bin to the authorized user thereof, and still permit the dumping of the trash bins without wasting any extra time by the garbage truck operator. The lids are provided with a special latch which is disabled to permit dumping through gravity action when the trash bin is lifted and inverted and dumped. In one case the mechanism includes a heavy spring which is compressed by the weight of the trash bin, and in another case a gravity operated latch releasing mechanism is employed. In each case, to open the trash bin while it is in the upright orientation, a key-operated release, either in the form of a padlock or a built-in lock mechanism, is used.</p> |
