Abstract: A food storage system mounted in a fresh food compartment of a refrigerator includes an enclosure defined by inner and outer housings, as well as a food receptacle slidably positioned in the inner housing. The inner and outer housings are spaced so as to define a zone therebetween within which air is forced to flow in order to cool the contents of the receptacle. A tunnel insert is positioned in a mullion zone defined between fresh food and freezer liners of the refrigerator, with the tunnel insert being formed with a through hole for directing the flow of cooling air into the food storage system, a channel for directing an exhaust flow of cooling air from the food storage system out of the fresh food compartment within the mullion zone and an enlarged opening defining a return air passage for the overall fresh food compartment. The tunnel insert, within the mullion zone, channels the exhaust air from the food storage system to the return air passage.

Abstract: A refrigerated product storage system incorporates first, second and third vertically spaced storage sections carried by a unitary support frame attached to an inner wall portion of a fresh food compartment door of a refrigerator. In the most preferred form of the invention, the storage system includes an uppermost dairy compartment, an intermediate chill compartment, and a lower, slidable drawer. The chill compartment is provided with a door which is pivotably mounted about a vertical, inboard pivot axis, with the door being formed with a cut-out handle portion adapted to be aligned with a passageway formed in a partition separating freezer and fresh food compartments of the refrigerator. With this construction, a supply of low temperature air is directed from the freezer compartment directly into the chill compartment through the cut-out handle portion. The door of the chill compartment is provided with a latching mechanism, preferably an over-center acting latching mechanism.
