Abstract
A multi-layer beverage container includes a multi-layer wall having an outer layer, a middle layer, and an inner layer. At least the inner layer is configured to flex inwards to accommodate a change in the sealed internal volume of the beverage container after a hot-filled beverage is filled inside the container and allowed to cool. The outer layer and inner layer delaminate from each other to accommodate this volume change, which allows the outer layer to retain its original shape. The middle layer functions to encourage delamination of the layers with respect to each other. A space corresponding to the volume change of the interior volume of the container is formed between the wall layers.
