Container with pressure control device for maintaining a substantially constant, preset pressure in the container, said container being arranged fo r dispensing a fluid, the pressure control device comprising a first chamber f or containing a pressure fluid, a second chamber in which a control pressure prevails and a third chamber which is formed by or communicates with, or is at least partially accommodated in an inner space of the container, while betwe en the first chamber and the third chamber there is provided a passage opening accommodating a closing member for closing, during normal use, the passage opening when the pressure in the third chamber is lower than the control pressure, a control means being movable by a displaceable or deformable part of the wall of the second chamber and arranged for displacing the closing member at least partially when the pressure in the third chamber is lower th an the control pressure, to enable pressure fluid to flow under pressure from t he first chamber to the third chamber, at least the control member and/or the second chamber being at least partially removable from the first chamber and biasing means being provided for keeping the closing member in the closed position when at least the control member and/or the second chamber are at least partiallyremoved.
