Abstract

A multi-layer beverage container made is disclosed. An outer layer encloses an inner layer that is configured to shrink or flex to accommodate volume changes of a beverage inside the beverage container caused by a change in temperature of the beverage in the sealed beverage container. The inner layer is not attached to the outer layer through the majority of the beverage container, with attachment zones being located at selected areas of the outer layer. There is a space between the inner layer and the outer layer. A gas introduction system is provided in the space to maintain a desired gas pressure in the space. The set gas pressure allows outer layer to be designed without the need to resist deformation caused by reduced pressure due to changing volumes of the beverage.
