ABSTRACT:
An air evacuation system is used for lining a container with a flexible liner. The container has a plurality of walls defining a cavity with an open top, and each wall has an interior surface and an exterior surface. The air evacuation system includes a platform for supporting the container in a formed state, wherein the container has the liner in an unseated position within the cavity. A vacuum assembly is coupled to the platform. The vacuum assembly includes a pump in airflow communication with at least one inlet positioned adjacent to the exterior surface of a first container wall. The vacuum assembly is configured to draw air using the at least one inlet from the cavity through the first container wall such that the liner is positioned substantially adjacent to the interior surface of the container in a seated position.
