ABSTRACT:
A fluid containment structure includes a containment vessel having an interior vessel space for fluid containment, and a fluid outlet communicating with the interior vessel space. A flexible bag with opposed side surfaces is disposed within the containment vessel, vented to an external atmosphere outside the containment vessel. A sacrificial bond structure is formed between the side surfaces, and restrains the side surfaces together until a back-pressure within the vessel space exerts sufficient force to break the sacrificial bond structure, allowing air from the external atmosphere to enter the bag and enlarge an interior bag space.
