Abstract
A dental amalgam dispenser is provided with a housing having an integrally formed funnel to prevent mercury leakage and with a rectangular plastic carriage framework reciprocal within the housing to carry the silver and mercury from separate inlet ports to the funnel for mixing. The carriage includes a pair of rails lying on either side of the inlet and outlet ports to prevent twisting of the carriage within the housing. A mercury reservoir is located atop the housing and is equipped with a micropore filter which prevents the formation of a vacuum in the reservoir chamber. The fineness of the openings in the filter at the same time prevents the passage of mercury therethrough.
