A container (1) supplied ready for filling with a liquid product such as beer includes a flexible bag (3) contained within a rigid outer body (2) with an outer space (4) in between, a first valve (6) for closing the bag (3) and a second valve (8) for closing the outer space (4). The first valve (6) is connected to a dip tube (7) which extends into the bag, and the first and second valves are contained within a neck fitting (5). The outer space (4) is pressurised to a first positive pressure relative to ambient atmospheric pressure and the bag (3) contains an oxygen-free gas such as nitrogen at a second positive pressure between the first positive pressure and atmospheric pressure.
A container (1) for filling with a liquid product, e.g. beer, including a flexible bag (3) contained within a rigid outer body (2) with an outer space (4) therebetween, a first valve (6) for closing the bag, and a second valve (8) for closing said outer space, in which the outer space (4) is at a first positive pressure relative to ambient atmospheric pressure, and the flexible bag (3) contains an oxygen-free gas at a second positive pressure between that of the outer space and ambient atmospheric pressure.
A method of preparing a container (1) for filling with a liquid product, e.g. beer, said container having a flexible bag (3) contained within a rigid outer body (2) with an outer space (4) therebetween, a first valve (6) for closing the bag and a second valve (8) for closing said outer space, said method comprising the steps of:
