  • Patent number: 5890615
    Abstract: The present invention comprises a tamper resistant garbage or waste container having an exterior housing, an interior bin suitable for receiving waste or garbage, with the interior bin further being provided with a pair of pivoting shafts which extend from either side of the interior bin into the interor of the housing, allowing the entire bin to pivot forward when in use. An additional biasing mechanism is secured to the top of the housing which prevents the bin from pivoting forward when unauthorized access is being attempted. A bias spring is further provided which is attached between the backside of the bin and the interior backwall of the housing, allowing the bin to readily and firmly return to its upright position when not in use.
