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 knock-down insulated storage and display unit which may be disposable. The refrigeration unit comprises standard components for colling air, an outgoing and a return duct, and a fan for causing the cooled air to be circulated out the outgoing duct through the knock-down unit and back into the return duct. The insulated knock-down unit is separate from but cooperates with the refrigeration unit, and is arranged for storing perishable items on its inside and for displaying printed material associated with the perishable items on its outside walls. The knock-down unit includes insulated outer walls, 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 an air plenum having extending ribs for forcing air to the insulated outer walls of the knock-down unit. The outer walls preferably include inwardly extending ribs for creating channels therebetween through which the air can flow. The knock-down unit may comprise walls and plenums of different sizes to permit different sized systems to be created using the same refrigeration unit.
