Abstract
A dispensing system is disclosed for use with a liquid dispensing package that includes a container and a system for forcing liquid from the container. The dispensing system directs liquid forced from the container to a defined area such as the eye and comprises a selectively operable nozzle that is mounted with the container to be movable relative thereto between liquid-dispensing and closed positions. The nozzle has an outlet orifice from which liquid is dispensed. An overcap is mounted in fixed relation with the container and defines an opening with which the nozzle orifice is registered when in the liquid-dispensing position. A shield, which directs liquid from the nozzle to the defined area, has an inlet aperture, a coupling arrangement for mounting the shield on the overcap with the inlet aperture registered with the overcap opening, and an outlet aperture remote from the inlet aperture. The construction of the nozzle, overcap and shield and the arrangement for mounting them on the container permits the nozzle to be moved, relative to the container, without moving the shield.
