Abstract: An energy saving inner door device for inhibiting the loss of cold air from a refrigerator when the refrigerator's outer door is opened, the device including a panel pivotally or hingedly attached to the inside of the refrigerator for closing off the volume of space between two adjacent refrigerator shelves. The panel can be pivoted between an upright position to close off the volume of space between the pair of shelves and thus trap the cold air therebetween, and a lowered position that allows the perishables stored on the lower one of the pair of shelves to be accessed. A latch is provided to hold the panel in the closed position and knobs are provided to facilitate the opening and closing of the panel.
