Abstract
An air flow control mechanism for a glass top refrigerator container wherein a flexible actuator is routed from a lateral front slide in a guide slot or track that runs back along one side to a damper or shutter at the rear. Accordingly, a cold air inlet at the rear such as used in a meat keeper or crisper pan is actuated by a lateral front slide without having a mechanical linkage that passes across the middle of the frame thereby obstrucitng the view down into the container. The flexible band is coupled to an operator actuable lateral slide mechanism at the front, and the band at the back is coupled to a shutter which moves laterally in response to the motion of the slide mechanism so as to open and close the rear cold air inlet.
