Abstract:
A method of forming a deli-style display case comprising:supplying a substantially rectangular sheet metal panel; stitching a metal front piece and a metal rear piece to a corresponding front edge and rear edge of the sheet metal panel and thereby forming a floor panel; suspending the floor panel above a metal subfloor panel, the floor nesting within a receiving surface of the subfloor panel and defining a space therebetween; stitching a first leg panel and a second leg panel to corresponding opposite sides of the subfloor panel; stitching a first interior panel and a second interior panel to the respective sides of the floor panel, the floor panel and each side interior panel joined along a series or overlapping flange edges; stitching an inner top panel along opposite sides of the top panel to a corresponding edge portion of the first side interior panel and the second side interior panel; stitching a first side exterior panel and a second side exterior panel, each exterior side panel defining a plurality of substantially right angle flanges, to corresponding flange members collectively defined by the side interior panel and adjacent leg panel, the first side exterior panel and the second side exterior panel defining a spaced gap opposite the adjacent surface of the respective interior side panel and respective leg panel; securing an exterior top panel opposite the interior top panel, said exterior top panel and said interior top panel defining a spaced gap therebetween, the top panel connected to an upper flange of the first and second exterior panels, wherein the spaced gap between the exterior top panel and the inner top panel is in open communication with the spaced gap defined between the respective interior side panels and respective exterior side panels, which is in further communication with the a spaced gap defined between the respective leg panels and exterior panels which is in further communication with the spaced gap defined between the floor panel and the subfloor panel; injecting a urethane foam into at least one of the defined gaps, the injected foam flowing through and interconnecting the gaps and thereby filling the gaps with a single interconnected foam layer.
