) along with the refrigerated propellant are measured into open up containers (commonly chilled). The valve-actuator assembly is then crimped onto the container to sort a strain-tight seal. Through the interval between propellant addition and crimping, adequate volatilization of propellant takes place to displace air in the container. During the “strain-fill” method, the concentrate is put while in the container, and possibly the propellant is compelled stressed through the valve orifice once the valve is sealed, or maybe the propellant is allowed to movement under the valve cap and afterwards the valve assembly is sealed (“beneath-the-cap” filling).
