Abstract: A method for producing a containing system for a liquid dispenser having a dimensionally stable outer container and a collapsible inner container, in the form of a pouch, arranged within the outer container. The method includes starting from the outer container, at least one layer of a pouch material being applied to an inner wall of the outer container. For this purpose, the pouch material is applied in the form of a liquid or powder to the inner wall, where, after solidifying or fusing, it forms a ply of a wall, of the inner container. The ply detaches from the inner wall of the outer container when the inner container collapses.
