ABSTRACT:
Mercury is dosed into a fluorescent or similar lamp from a container shaped mostly as an elongated flat plate, inserted lengthwise into the exhaust tube and held in place by a rib in the tube engaging depressions in the center of the plate. To permit easy insertion, the end of the plate opposite the mercury container has a relatively large through hole, leaving a thin resilient wall on each side of the hole so that insertion force is minimized.
