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