Abstract
A manually operable sprayer mountable on a supply container comprises a pump cylinder supporting a cylindrical, rollable pump diaphragm having a closed end coaxial with the cylinder and linearly axially displaceable toward and away from the cylinder by a trigger and pump actuator assembly including a pivotal trigger interconnected with a pump actuator for pivotal displacement of the trigger to be translated into linear axial displacement of the actuator which is connected to the end wall of the pump diaphragm. The component parts are enclosed in a housing defined by a pair of hingedly connected housing members, and a retainer member by which the sprayer is mountable on a supply container by a threaded cap either supports the component parts as a unitary assembly or interengages with the housing to cooperatively support the component parts therewith.
