A method of making a container for an aerosol, the method comprising:
- providing a first preform for an outer container having an open neck;
- providing a second preform having a neck for a valve cup and having a body for a bag and being integrally joined to the neck;
- disposing the second preform in the first preform;
- simultaneously blow molding the first preform and the second preform to yield an outer container, a bag therein with an integral valve cup proximate the neck of the second preform,
- installing propellant between the bag and the outer container;
- and
- sealing the valve cup to the neck of the outer container so that the propellant is disposed between the bag and the container, the bag being suitable for receiving product in the bag and being dispensable therefrom in response to user actuation of a valve.
