Abstract:
A container (1) with pressure control device (8, 108, 208, 308, 408, 508) for maintaining a substantially constant, preset pressure in the container, said container (1) being arranged for dispensing a fluid, the pressure control device comprising a first chamber (24, 124, 224, 324, 424, 524) for containing a pressure fluid, a second chamber (60, 160, 260, 360, 460, 560) in which a control pressure prevails and a third chamber (62, 162, 262, 362, 462, 562) which is formed by or communicates with, or is at least partially accommodated in an inner space of the container (1), while between the first chamber (24, 124, 224, 324, 424, 524) and the third chamber (62, 162, 262, 362, 462, 562) there is provided a passage opening (28. 128, 228, 328, 428, 528) accommodating a closing member (40, 140, 240, 340, 440, 540) for closing, during normal use, the passage opening (28. 128, 228, 328, 428, 528) when the pressure in the third chamber (62, 162, 262, 362, 462, 562) is lower than the control pressure, a control means (66, 166, 266, 366, 466, 566) being movable by a displaceable or deformable part (58, 158, 258, 358, 458, 558) of the wall of the second chamber (60, 160, 260, 360, 460, 560) and arranged for displacing the closing member (40, 140, 240, 340, 440, 540) at least partially when the pressure in the third chamber (62, 162, 262, 362, 462, 562) is lower than the control pressure, to enable pressure fluid to flow under pressure from the first chamber (24, 124, 224, 324, 424, 524) to the third chamber (62, 162, 262, 362, 462, 562), biasing means being provided for biasing said closing member to a closed position, characterized in that at least the control member (66) and/or the second chamber (60, 160, 260, 360, 460, 560) are at least partially removable from the first chamber (24, 124, 224, 324, 424, 524) and said biasing means (42, 142, 242, 342, 442, 542) being provided for keeping the closing member (40, 140, 240, 340, 440, 540) in the closed position when at least the control member (66, 166, 266, 366, 466, 566) and/or the second chamber (60, 160, 260, 360, 460, 560) are at least partially removed, such that the first chamber (24, 124, 224, 324, 424, 524) can be filled while the second chamber (60, 160, 260, 360, 460, 560) and/or the control means can be stored and transported separately from the first chamber (24, 124, 224, 324, 424, 524).
