Abstract (en)
[origin: WO9101252A1] The invention concerns a process for filling pressurized-gas packs, as well as the pressurized-gas packs themselves which comprise a casing (1) containing a pressurizing agent and in which is located at least one flexible bag (2) designed to hold the liquid constituting the contents of the pack. The interior of the flexible bag (2) is closed off by a valve (6) located in the region of the mouth (4) of the casing (1). In order to improve the above-mentioned process and the associated pressurized-gas pack, so that not only any pressurizing agent, in particular air, but also commercially available casks can be used and the whole filling operation carried out in a relatively short time and hence with correspondingly less expenditure of resources, it is proposed that the flexible bag (2) is accommodated in the casing (1) in such a way that there is a gap (5) between the edge (3) of the bag opening and the mouth (4) of the casing (1), and the pressurizing agent is introduced through this gap (5). The edge (3) of the bag opening is hermetically closed off together with the mouth (4) of the casing (1) by the valve(6) which is actuated for the interior of the bag (2) to be evacuated and actuated again for the contents to be introduced into the bag (2). The interior of the bag (2) is evacuated by connecting it to a vacuum. The bag (2) is designed as a gusset bag with the gussets facing inwards.
