Method and apparatus for inserting a flexible inner container within a rigid outer container

Abstract

A method for pressurizing an aerosol dispensing system with propellant in which a flexible inner container is inserted within a rigid outer container. The mouth opening of the inner container, having flexible means thereon, extends outwardly through the neck opening of the outer container with the flexible means supported by the neck opening. A dispensing cap is moved into engagement with the flexible means and the dispensing cap and flexible means are moved away from the neck opening while propellant is then injected through the neck opening into the region between the inner and outer containers. The dispensing cap is moved into the neck opening and crimped into engagement therewith to fix the position of the flexible means and inner container while maintaining a space between the neck opening and a portion of the exterior surface of the dispensing cap during crimping.
