24 Abstract A valve fitment (3) for a two-chamber compressed gas packaging means with product components in an inner and an outer container (1, 2) for mixing thereof in the outer container (1) before discharge of the mixture has a discharge pipe (6) which is sealingly axially displaceably guided in an opening (17) in a cover (7) of the outer container (1), which is smaller than the outside diameter, for simultaneously piercing a wall portion (5) of the inner container (2), and a valve (11, 14) which is actuable to release the mixture. In order to ensure that discharge cannot take place before the mixing operation, the cover, for coupling the inner container in position, internally carries a coupling means (8) which is disposed around the discharge pipe and which has product through- flow openings (23, 27), wherein the valve can be actuated by displacement of the discharge pipe from the outer limit position in which the valve is closed, by way of an intermediate position in which the wall portion of the inner container is pierced and the valve is still closed, into the other limit position in which the valve is opened.
