  • Patent number: 5028196
    Abstract: During a normal waste collection service, an automated loading mechanism is used to empty the contents of a bin into a refuse vehicle. The bin has a closable lid which includes a message on its underside such that the message is displayed when the lid is open. The message indicates that recyclable wastes, such as glass, paper or the like are to be collected in a subsequent collection to the normal waste collection. A lid opening device including a lever arm which operates to automatically open the lid of the bin is employed during an emptying operation so as to display the message. This message indicates to the homeowner that the required recyclable waste can be placed into the bin, and by closing the lid, the collection service is signaled to empty the contents of the bin.
