A dispenser body molded of plastic material includes an upper body portion on which a trigger is swingably pivoted and a vertically extending lower tubular portion. A piston has an L shape and includes an upper folded horizontal portion carried by spaced vertical wall portions of the upper body portion. The piston is vertically disposed in the upper body portion. A nozzle member is mounted on the terminal end of the upper folded horizontal portion. An outlet conduit, communicating with an orifice formed in the nozzle member, is formed in the piston. A cylinder coupled to the trigger is disposed to slide vertically along the piston within the lower tubular portion. The cylinder defines a pump chamber communicating with the outlet conduit. An inlet conduit communicating with the pump chamber is formed in the cylinder. A compression spring, seated in the cylinder at the lower end thereof and abutting on the lower end of the piston at upper end thereof, biases the cylinder to its lower non-operation position.
