ABSTRACT:
A refrigerated display system for the in-store display of perishable items is disclosed. The display system comprises a reusable refrigeration unit and a disposable insulated storage and display unit. The refrigeration unit comprises a cooling means for cooling air, an outgoing and a return duct, and a fan for causing the cooled air to be circulated out the outgoing duct through the disposable unit and back into the return duct. The disposable insulated unit is separate from but cooperates with the refrigeration unit. The disposable unit is arranged for storing perishable items on its inside and for displaying printed material associated with the perishable items on its outside walls. The disposable unit includes a door through which the perishable items may be loaded and removed, a pair of duct openings corresponding to the ducts of the refrigeration unit, and air diverting means for causing air cooled by and received from the refrigeration unit to circulate before returning to the refrigeration unit via the return duct. The air diverting means preferably comprises an air plenum having extending ribs for forcing air to the insulated outer walls of the disposable unit. The outer walls preferably include inwardly extending ribs for creating channels therebetween through which the air can flow.
