An enclosure structure including a cabinet having an insulative wall defining an internal space selectively closed by a closure member hingedly mounted to the cabinet. The end of the insulating space in the wall is closed by a cooperating breaker collar, inner liner, and outer shell flange structure arranged to be free of protuberant portions for nonbinding, wiping movement of the closure gasket thereagainst in the selective positioning of the closure member between open and closed positions. In the illustrated embodiment, the shell flange includes a turned distal portion projecting downward with respect to the insulating space and the breaker collar includes a distal connecting portion embracing the turned distal portion of the flange to provide a positive connection of the breaker collar to the shell. The breaker collar is thusly effectively recessed relative to the shell flange to provide for free movement of the closure gasket without binding in moving to and from the closed position of the closure relative to the cabinet.
