A two-chamber pressurized package has an outer body which encloses an interior space, which can be subjected to pressure, and forms an opening through which an inner body of a material which can fold or be crumpled is inserted, prior to flanging, of the opening, filling of the inner body and fitting of a valve in the region of the orifice, the outer body and inner body are connected to one another in a predetermined region and are then folded over together to form a flanged edge; in this way problems associated with fitting a funnel to the package by hand are overcome. |
