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.

A method for pressurizing an aerosol dispensing system with propellant, which dispensing system includes a flexible inner container having a mouth opening, a rigid outer container having a narrowed neck opening, the inner container positioned within the outer container, a dispensing cap joined to the neck opening of the outer container with the cap in communication with the inner container, and a propellant in the region between the exterior of the inner container and the interior of the outer container to exert pressure on the exterior of the flexible inner container, said method comprising: inserting the flexible inner container within the rigid outer container with the mouth opening of the inner container extending outward through the neck opening of the outer container; said inner container having flexible means extending around said mouth opening; supporting said flexible means on the neck opening of the outer rigid container; placing the dispeNsing cap for the aerosol system in alignment with the neck opening of the outer container; moving the dispensing cap relative to the flexible means on the mouth opening to firmly engage the flexible means with the exterior surface of the dispensing cap; moving the dispensing cap away from the neck opening of the outer container with the flexible means in engagement with the exterior surface of the dispensing cap; injecting propellant through the neck opening of the outer container into the region between the exterior of the inner container and the interior of the outer container; moving the dispensing cap into the neck opening of the outer container; crimping the dispensing cap into firm engagement with the neck opening with the crimping applying a gripping force to the flexible means to fix the position of the flexible means and the inner container through contact of the dispensing cap and the neck opening with the flexible means, and maintaining a space between the neck opening and a portion of the exterior surface of the dispensing cap during said crimping to prevent tearing of the flexible inner container during the crimping operation.
