A compartmented container, such as an aerosol container, has a plastics pouch (12) attached to a top component such as an aerosol cone (1). The cone is typically formed of steel laminated with polypropylene, and the pouch is attached to the cone by means of a platics/plastics heat-sealed bond using the polypropylene surface layer of the cone. The pouch is attached to the cone (1) at an area away from that used to attach the cone to an aerosol container with a double seam. The cone typically has an annular countersink (4) and the pouch is attached either to the outer countersink wall (5) or the inner countersink wall (6).
