  • Patent number: 4890760
    Abstract: A trash receptacle including a valve mounted in the bottom thereof for breaking a suction which is created when the trash liner positioned within the receptacle is lifted for the purposes of trash removal. The valve is mounted in the central, raised bottom portion of the container. The central portion forms a recess portion and is surrounded by a periperal portion having radially extending passages. The valve includes a flexible diaphragm the peripheral portion of which remains in sealing engagement with the inside surface of the container and covers the air holes extending from the outside surface to the inside surface of the container. When the liner is lifted, the diaphragm flexes upwardly due to the suction pressure and allows air to flow inwardly to break the suction.
