Abstract:
A container with pressure control device for maintaining a substantially constant, pre-set pressure in the container, the container being arranged for dispensing a fluid, the pressure control device comprising a first chamber for containing a pressure fluid, in particular a pressure gas, a second chamber in which at least during use a control pressure prevails, and a third chamber which is formed by or is in communication with, at any rate is at least partly included in an inner space of the container, while between the first chamber and the third chamber a passage opening is provided in which a closing member is included for closing the passage opening during normal use when the pressure in the third chamber is higher than the control pressure, while a control means is movable by a displaceable or deformable part of the wall of the second chamber and is arranged for at least partly displacing the closing member when the pressure in the third chamber is lower than the control pressure, such that the pressure fluid can flow under pressure from the first chamber to the third chamber, characterized in that prior to use the control means have been brought into a position in which they are at least functionally uncoupled from the closing member, and the pressure control device is arranged for functionally coupling the control means to the closing member through an activation step prior to use.
