A pressure vessel having a removable lid for storing objects under pressure is disclosed. The pressure vessel includes a pressure chamber having a smooth walled opening of uniform size against which the removable lid seals with an interference fit. A stop is secured to the pressure vessel and restrains one end of the removable lid from sliding along the smooth wall. At the other end of the lid there is pivotally mounted a locking member which engages under a locking projection fixed to the pressure vessel. A lever arm, pivotally attached to the locking member, uses a levering projection (fixed to the pressure vessel) as a fulcrum to assist in fitting the lid to and removing the lid from the pressure vessel. The pressure vessel is provided with a valve for manually dumping pressure from the pressure chamber and is also provided with a source of pressurized fluid for pressurizing the chamber to a predetermined amount of pressure.

A pressure vessel for storing objects under pressure, said pressure vessel comprising: a pressure chamber having an opening, a removable lid closing said opening, a floating radial pressure seal between said removable lid and said opening, said removable lid floating with respect to said opening and thereby; external restraining means acting between the floating removable lid and the pressure vessel; a valve mounted in said pressure chamber for dumping pressure from said chamber when said chamber is pressurized; and a source of pressurized fluid for pressurizing said chamber to a predetermined amount of pressure, wherein upon said pressure chamber being pressurized said floating removable lid floats within said opening, said pressure causing said lid to clamp against said external restraining means to prevent accidental release of pressure without axially compressing the pressure seal, said lid only being releasable from said clamping upon release of the pressure from the pressur chamber.
