Abstract

A vacuum insulated structure (12) includes a first cover member (72) of a stamped unitary sheet defining a perimeter portion (66, 68) positioned at a first planar level (P1) and a reinforcing member formed in the interior sheet extending to a second planar level (P2) spaced axially outward and disposed radially inward of the perimeter portion (66, 68). The vacuum insulated structure (12) also includes a second cover member (74) and a thermal bridge (22) interconnecting the first cover member (72) and the second cover member (74) at the perimeter portions (66, 68) thereof to define an insulating cavity (24) therebetween. The insulating cavity (24) is a sealed cavity (24) having a vacuum drawn therefrom, and the first reinforcing member is configured to reduce deformation of the first cover member (72) in at least an area adjacent the reinforcing member and to define a portion of a path for air flow out of the sealed cavity (24) during a vacuum draw process.
