The foodstuff-displaying refrigerator unit comprises a box-like container, having an enclosure upwardly opening through a top mouth. A door aperture is defined about a side wall of the container. A vegetable-supporting platform is freely mounted into the enclosure for vertical movement therethrough. A pallet is supported by a first conveyor, itself resting on the container flooring. Inflatable balloons are provided between the pallet and the platform, for power lifting the platform. An air compressor feeds air into the balloons, and furthermore cools the air within the container enclosure beneath the platform. The top layer of foodstuff supported by the platform can thus be adjusted by the inflatable balloons, to remain substantially about the plane of the top mouth of refrigerator enclosure, to facilitate inspection of and access to the foodstuff independently of the level of progressive attrition of foodstuff from successive foodstuff withdrawal by customers.

A foodstuff-displaying refrigerator unit for use in a grocery store, comprising in combination: (a) a container, having a peripheral side wall member and a bottom flooring, whereby an enclosure is defined, said enclosure upwardly opening through a top mouth; (b) a platform, freely engaged into said enclosure for vertical movement therethrough along said side wall member, said platform defining an overlying loading volume for supporting and circumscribing perishable foodstuff goods in vertically stacked layers; (c) means for power lifting said platform from a lower limit position, proximate said flooring, to an upper limit position, proximate said mouth, said lifting means including an inflatable balloon member, directly engaging the underface of said platform and supported by said flooring, air feed means, for feeding pressurized air into said balloon member for inflating the latter, and control means, for actuating said air feed means upon the volume of said foodstuff goods in said platform loading volume reaching a set threshold level; and (d) cooling means, for continuously cooling the air within said foodstuff loading volume; wherein the level of top layer of said foodstuff goods within said loading volume is adjusted by said control means to remain substantially about the plane of said top mouth of refrigerator enclosure, upon progressive depletion of foodstuff goods due to the picking up of the foodstuff goods by the grocery store customers, so as to maintain ease of inspection of and of access to the foodstuff by the customer.
