A pressure regulating system for a beverage container system, comprising a first compartment for containing a pressurized, in fluid communication with a surrounding space through at least a gas valve for opening and closing a passage between the first compartment and surrounding space, wherein a gas valve control system is provided, comprising a deformable and/or movable wall or wall part, wherein said deformable and/or movable wall part is operably in contact with said gas valve for opening and/or closing said gas valve, wherein a second compartment is provided at a side of the said deformable and/or movable wall part, said movable and/or deformable wall part forming a wall of said second compartment, wherein the second compartment forms a pressure regulating space and comprises a wall part formed by or comprising at least a gas permeable, liquid tight permeable wall part.

Pressure regulating system for a beverage container and beverage container provided therewith

A pressure control device for controlling a pressure in a beverage container comprises a gas filled pressure control chamber enclosed by a wall of the pressure control device. The wall has an inner surface facing the chamber and an outer surface facing away from the chamber, the inner surface and outer surface defining a thickness of the wall. A scavenger material is provided in the pressure control device for capturing gas that enters, during use, into the pressure control chamber. The scavenger material is distributed over the wall thickness with a predetermined concentration from the inner surface towards the outer surface of the wall such that a rate of gas capture by the scavenger material changes over time.

Beverage dispensing system, beverage container and pressurizing system for use in a beverage dispensing system or container

A pressure regulating system for a beverage container includes a first compartment for containing a pressurized gas. The first compartment is in fluid communication with a surrounding space through a gas valve for opening and closing a passage between the first compartment and surrounding space. A gas valve control system includes a deformable and/or movable wall or wall part, which is in contact with the gas valve for opening and/or closing the gas valve. A second compartment is provided at a side of the deformable and/or movable wall part. The movable and/or deformable wall part forms a wall of said second compartment and the second compartment forms a pressure regulating space and includes a wall part formed by or including at least a gas permeable, liquid tight permeable wall part.

A pressure control device () for medium-containing containers () such as liquid or gas containers, which pressure control device comprises a pressure control chamber () with at least one movable wall part () for operating a mechanism for opening and/or closing a gas supply opening () of a gas holder, while a scavenger () is accommodated in the pressure control chamber. Preferably, the pressure control device is stored at atmospheric conditions before the beverage and the pressure control device are brought into contact.
