Abstract:
1. A method of preparing an aerosol spray container at a point of sale retail location comprising, a) loading a blank can into a can filling machine, where the blank can comprises an internal can volume containing an initial liquid formulation and pre-pressurized with a propellant, the blank can having an adaptor connection; b) selecting an additive liquid; c) withdrawing the additive liquid from a container into a syringe comprising a barrel, a distal end and a proximal end and configured to fit inside a rigid cup of a filling machine, where the syringe has a plunger having an attached piston configured to slidably and sealably fit within the barrel such that proximal sliding movement of the plunger and piston withdraws the additive liquid from the container into the barrel; d) transferring the syringe with the withdrawn additive liquid into the rigid cup positioned in the filling machine; e) connecting an adaptor to the adaptor connection to establish a fluid communication between the additive liquid in the syringe and the internal can volume; and f) injecting the additive liquid into the internal can volume using a drive mechanism located on the can filling machine.
