2049021 9010583 PCTABS00002 A double-chambered package with an essentially rigid outer container (1) fitted with an outlet valve (2) for a product in fluid or paste form and an inner container arranged in the outer container (1) for a pressurised gas like compressed air or the like, in which the inner container (3) takes the form of a flexible bag and where the outlet valve (2) includes an outlet tube (17) fitted in a valve body (14) so as to be movable from a closed to an open position and vice versa. To simplify construction, increase reliability and reduce harm to the environment, the inner bag (3) is connected to the outlet valve (2) and can be filled via it with pressurised gas after the outer container (1) has been filled so that, when the outlet valve (2) is opened, the product can be forced out of the outer container (1) through the corresponding expansion of the inner bag (3).
