Abstract
A method of making a vacuum insulated refrigerator cabinet structure includes thermoforming a first polymer sheet to form a wrapper having a base wall and four sidewalls. The method also includes thermoforming a second polymer sheet to form a liner having a base wall and four sidewalls. Elongated corner stiffeners are adhesively secured to inside corners of the wrapper. A resilient ring is adhesively secured to the wrapper and liner. The resilient ring includes pins that are received in openings of the elongated corner stiffeners. Porous material is disposed in a vacuum cavity between the wrapper and the liner.
