A pressure control system provided for maintaining a constant predetermined excess pressure in a fluid dispensing container comprises a high-pressure plastic vessel having an inner chamber, and a pressure control device having a valve and mounted on the open end of the high-pressure vessel, whereas a passageway is provided from the inner chamber to the outside, which is controlled by the valve. A piston with a protruding stem is provided in a guide member, whereas between the guide member and the piston a chamber with a gas with a reference pressure smaller than the high pressure is enclosed, and the high pressure vessel is closed by a closure with a central bore of smaller diameter than the diameter of the stem, and the piston end remote from the protruding stem is pressurized by the fluid in the fluid dispensing container.

A novel pressure control system is provided for maintaining a constant predetermined excess pressure in a fluid dispensing container, comprising a high-pressure plastic vessel having an inner chamber, a closed end and an open end, and a pressure control device with a valve, which pressure control device is mounted on the open end of the high-pressure vessel, whereas a passageway is provided from the inner chamber to the outside, which is controlled by the valve, wherein the high-pressure vessel is essentially spherical.

A pressure control device for pressure packaging based on a disc with fluid connection and a collecting basin, with associated closing means. The closing mechanism in the pressure control device is no longer based on a cylinder with a central opening in the separation wall and closing-off of the opening by means of a piston with stem. The proposal is extremely simple, compact and easy to assemble. The use of O-rings is superfluous. A method for manufacturing a pressure control system and a kit of parts for the assembly thereof.

The invention relates to a dispenser container for pressurized fluids, comprising: a metal shell forming at least part of an outer wall of the container, which metal shell at least partly encloses an internal container volume, a partition wall separating internal container volume into a high-pressure chamber and a low-pressure chamber, and a valve mounted into the partition wall in a substantially fluid-tight manner, which valve is configured for a controlled release of fluid from the high-pressure chamber to the low-pressure chamber, wherein the partition wall is at a sealing zone sealed to the metal shell in a substantially fluid-tight manner, and wherein the metal shell delimits at least a part of the high pressure chamber. The invention further relates to a dispenser comprising such a dispenser container and a method for manufacturing such a dispenser container.

Beverage dispensing system, beverage container and pressurizing system for use in a beverage dispensing system or container. Beverage dispensing system 1 comprising a beverage container 2 with a beverage compartment 3 and a pressurizing system 10, wherein the pressurizing system 10 comprises a gas container 11 comprising pressurized gas, a closure 13 closing the gas container 11 and a pressure regulator 12 operative for opening the closure 13 for allowing gas to enter into the beverage compartment 3 from the gas container 11, wherein the pressure regulator 12 comprises a regulating chamber 15 having at least a wall part 17 movable and/or deformable based on pressure in the beverage compartment 3, wherein at least one opening 24 is provided through a wall 18 of the regulating chamber 15 providing for at least part of a gas passage between the regulating chamber 15 and the beverage compartment 3.

Adsorbent materials adsorb large quantities of inert permanent gases and maintain the initial pressure inside aerosol packages throughout the useful life of the packages, thus acting as propellants.
