Abstract

The container has an outer cylinder (1) which screws over an inner container (13). The inner container has an 'O' ring which fits around and seals the end piston (6). The space above the piston (CV) is under vacuum until pressurised by a charge of gas from the main cylinder. When the pressures are equalised in the cylinder space (CV) the contents may be discharged until the charge is exhausted. A further adjustment of the cylinder position is then necessary until a fresh charge is required. the product and propelling gas are stored in the central cylindrical volume (CL).
