ABSTRACT:
A liquid container comprising a multi-layer container including a wall made up of a main layer and a separate, delaminatable inner layer, a container opening at the top for filling and evacuation and a plurality of air vents extending completely through the main layer and terminating at the inner layer, such that the inner layer delaminates when liquid is evacuated by suction. The inner layer is thicker at the top end of the container and the air vents have a larger size opening at the bottom of the container, both to prevent premature collapse of the top end of the inner layer. The inner layer is also at least partially predelaminated during (or right after) manufacturing to assist ease of delamination during use.
