Abstract
The invention relates to a source chemical container assembly, comprising a metal container functioning as a vacuum chamber and provided with a removable closure, which removable closure seals against the metal container with a metal seal. In order to facilitate easy recharging of the container assembly, compressive force is applied to the metal seal through a tension chain. In a preferred embodiment of the invention the metal seal and the tension chain are provided along a circumference of said metal container. The assembly can comprise an inner container in which the source chemical is contained.
