Valve assembly for use in dispensing beverage

A valve assembly for a container in which an inner bag is provided for receiving beverage, in particular carbonated beverage, wherein a beverage valve is provided which on a side facing the inner bag is provided with a communication with an inner space of the bag and on the opposite side from said side facing the inner bag is provided with means for operation of the beverage valve by a tapping device in which the container is receivable, wherein the beverage valve, on the opposite side, is surrounded by an upstanding first apron which is gas-tight, while along an outer side of said first apron, at a distance therefrom, a second apron is situated, also gas-tight, while between the first and the second apron a bottom wall with at least one gas passage opening is provided which during use is in communication with a space enclosed between the inner bag and the container surrounding the inner bag, the arrangement being such that during use a collar of a connecting element abuts gas-tightly and liquid-tightly against the second apron, while a dispensing element abuts gas-tightly and liquid-tightly against the first apron, so that between the two aprons a chamber is formed through which during at least part of said use gas under pressure is forced through said at least one gas passage opening, separately from the beverage.
