  • Pressure vessel
    Patent number: 6817764
    Abstract: An improved pressure vessel comprising a polymer inner bladder inside a containment envelope is provided which is well-suited for transporting hazardous materials therewithin via air transport. The improved pressure vessel features a seal placed over the closure of the containment envelope which has been found to suppress failure of the pressure vessel by creep which occurs as a result of the high internal pressure that the pressure vessel experiences at high altitudes. The seal also serves to indicate whether or not the containment envelope has been tampered with after having been sealed.
