<p>A method of inserting a barrier pack (2), with a perimeter flange (10), into a container (30) to be pressurized. The container to be pressurized includes a base, a side wall, and a dome (95) having a perimeter bead (40), with the perimeter bead of the dome defining an opening having a transverse cross-sectional area which is less than a transverse cross-sectional area defined by the side wall of the container to be pressurized. The method comprising the steps of forming the barrier pack with a transverse dimension which is less than a transverse dimension of the opening of the dome. Inserting the barrier pack, with the transverse dimension less than the transverse dimension of the opening of the dome, through the opening of the dome, without application of force, so that the barrier pack is accommodated within an internal compartment of the container to be pressurized with a flange of the barrier pack supported by an annular bead of the dome. Applying a mounting cup (32), supporting a valve assembly (38), and crimping the mounting cup to the dome. Filling the barrier pack with a product to be dispensed, pressurizing the container and affixing an actuator to a valve stem of the valve assembly.</p> |
