A refrigerated showcase has a front opening through which a consumer can view and access foodstuffs on display. The foodstuffs are cooled by coolant air introduced through a slanted, perforated, interior panel located near a rear wall of the showcase. An air curtain directed downwardly at the front opening minimizes coolant air loss through the opening. Lips are applied and extended from the edges of vertical sides of the access opening to reduce the loss of coolant air through the air curtain. Thus, relative flows of coolant air and the air curtain are maintained inside the showcase.
