Abstract

A manually actuated pump that dispenses liquid substances in measured quantities from the contents of bottles and containers which is comprised of a handle capable of being axially displaced against the action of a spring, a cylinder having a pump space whose volume is reduced on manual actuation of the handle, a feed tube connected to the cylinder, a piston driven by the handle that displaces the volume in the cylinder, and two valve-closing surfaces for alternately opening and closing the passage leading to the feed tube and the discharge duct contained in the handle so that only a known measured quantity of liquid will be dispensed from the bottle.
