A pump dispenser and a method of assembling the pump dispenser

摘要

A cover (16) is horizontally pushed toward an inner assembly (52) which is a unit composed of all structural elements except for the cover (16) and mounted on the inner assembly (52). The cover (16) is fixed to the inner assembly (52) at three portions. An engaging projection (16-2) on the inner surface of the ceiling of the cover (16) engages a horizontal engaging groove (42-3) formed in the upper surface of the nozzle base (42) from the right side by pushing the cover (16) toward the inner assembly (52). A horizontal engaging piece (16-3) on the lower end of the cover (16) engages with a space between horizontal engaging piece (16-3) on the lower surface of the cylinder (12) and a horizontal engaging piece (38) formed on the upper surface of the valve housing (14) on the right side. A fitting hole (16-1) is formed in the upper surface of the ceiling of the cover (16) and is mounted on the fitting projection (42-2) in the upper surface of the nozzle base (42) from above. <IMAGE>
