ABSTRACT:
A pressure vessel is described which includes a flexible, air permeable, liquid permeable, containment envelope having an interior cavity and an access opening closed by a closure. A flexible, air tight, liquid impervious, inner bladder is provided having an interior cavity and an access opening sealed by a closure. The inner bladder is disposed within the interior cavity of the containment envelope. The containment envelope is dimensionally stable at the maximum intended pressures. The inner bladder in a fully expanded condition is larger than the containment envelope such that internal pressure acts upon the inner bladder to place the inner bladder in compression within the interior cavity of the containment envelope while placing the containment envelope in tension. The pressure vessel, as described, can be made from low cost materials such as a sealable polymer plastic bag and an envelope of spun bonded olefin material.
