A refrigerated open display case achieves a laminar flow of chilled air over flowers or produce displayed therein, and establishes a laminar flow boundary layer with the warmer ambient air. There is an array of perforations serving as chilled air supply openings on each of the vertical riser walls, so that the chilled air is discharged in a laminar flow. A return air intake grille extends across the cabinet below the front of the lowermost shelf, in an undercut transverse recess. The front part of the lowermost shelf member can have a chamfer or downward slope, so that debris that falls on it drops to the floor in the front of the cabinet, where it can be routinely swept up. The recess below this chamfer can likewise have a slanting lower wall. Inside the cabinet, the coldest air leaving the evaporator coil passes in contact with the underside of the shelf members, so these shelf members are also kept chilled. Vases or flower containers, which can be metal, are positioned in open receptacles in the shelves, with the bottoms of the vases or containers projecting down into the cold air tunnel.

[ I claim:] [9.] Refrigerated open display case for flowers or other merchandise, with laminar flow boundary layer, comprisinga cabinet having a back, sides and an open front display portion the front display portion including a plurality of horizontal shelf members arranged in parallel staggered stair-step fashion, and a plurality of vertical riser walls disposed respectively behind said shelf members and between successive ones of said shelf members; andair cooling means within said cabinet for producing a continuous laminar flow of chilled air over said shelf members, including a return air intake disposed across said cabinet below a front of a lowermost one of said shelf members; chilling means for chilling air that enters said return air intake; a plurality of chilled air supply opening arranged across each of said vertical riser walls for discharging said chilled air in a laminar flow path over said shelves towards said return air intake; and means for moving air from said return air intake through said chilling means to said chilled air supply openings;wherein said return air intake comprises a recess extending transversely below the front of said lowermost shelf member and having an undercut transverse wall, with a return air grille being disposed in said undercut transverse wall; and wherein said lowermost shelf member has a chamfered front portion above said return air intake.
