A cartridge containing a self-setting composition, preferably comprising an interactive resin component and a hardener therefor, is formed of a single piece of skin. The skin is folded into tubular form with one side portion overlapping the other, and the margin of the overlying side portion is heat sealed to the underlying side portion, preferably by means of a heat sealable adhesive coated on the skin, which adhesive is not resistant to an ingredient of the interactive component, e.g. styrene. A flap is defined by the underlying side portion, and one interactive component is located on each side of the flap. The flap stops short of the facing wall, and the interactive components meet in the gap and react together to a polymerised interface. A method of making the cartridge is disclosed. |
