Abstract
Official abstract text for this publication.
A vacuum insulated cabinet structure for refrigerators and the like includes a plurality of vacuum insulated panels. The cabinet structure may include an “O” or “U” structure that is formed by folding a large panel assembly. The panels may comprise side walls that are heat-sealed together around the perimeters of the panels to form air-tight spaces having a vacuum.
First claim
Opening claim text (preview).
