ABSTRACT:
A balloon or airship having a hull of flexible material is provided with a deflation opening in the hull and a rigid frame permanently fastened to the edge of the opening. A ring of flexible sheet material has its peripheral edge removably clamped to the rigid frame. A disc of flexible sheet material larger than the central opening in the ring is fastened by an adhesive to the ring all around the central opening in the ring. A deflation tape sewed to the disc near the edge of the upper half thereof has a central free end to be pulled for peeling the adhesive-held disc from the ring to rapidly deflate the balloon.
