ABSTRACT:
A barrier aerosol package wherein a product bag is positioned in a container and has the upper portion gathered and sealed to the container curl defining a valve cup receiving opening. A tool is provided for receiving the upper part of the product bag and supporting the bag for the application of a band of adhesive, after which the tool is utilized to collapse the bag while uniformly folding or gathering that part of the bag to which the adhesive has been applied. The tool then applies the collapsed bag to the container and trims the excess bag material, after which the bag is inflated to restore its initial configuration followed by the removal of the tool.
