The invention concerns a valve for distributing two fluids contained in a rigid flask by propulsion means, the first fluid having to be contained in a first flexible pouch, and the second fluid in the flask so as to be isolated from the first fluid before the fluid leaves through the valve, the valve comprising an internal part that, when the valve is placed on the flask, is situated inside said flask, and an external part that, when the valve is placed on said flask, is situated outside the latter, a first passage connecting the inside of the first pouch and the space surrounding the external part of the valve, said first passage being provided with first closure means, a second passage connecting the space intended to receive the second fluid and the space surrounding the external part of the valve, said second passage being provided with second closure means. The valve of the invention is distinguished from those known from the prior art by a second flexible pouch for receiving the second fluid that is fixed to the valve, said second flexible pouch being placed around the first.
