ABSTRACT:
A collapsible air vent closure is disclosed comprising a frame having a frame aperture. A closure is mounted to the frame for pivoting between a closed position and an open position. A movable vent wall having a vent orifice is interposed between the frame and the closure. The vent orifice provides an air flow path to the frame aperture when the closure is in the open position. The closure inhibits the air flow path to the frame aperture when the closure is in the closed position.
