Patent ID: 7997449

Claim:
A fluid delivery system for dispensing two fluids, the fluid delivery system comprising: a first container having a first fluid; a body attached to the first container; a fluid inlet conduit in fluid communication with the first container; a pump for drawing the first fluid through the fluid inlet conduit and into a pump chamber; a fluid discharge conduit downstream of the pump chamber, the fluid discharge conduit being in fluid communication with the pump chamber and a discharge orifice, the pump discharging the first fluid from the pump chamber into the fluid discharge conduit; a second container having a second fluid; and means for delivering the second fluid into the fluid discharge conduit whereby the second fluid mixes with the first fluid when the first fluid is discharged into the fluid discharge conduit such that a mixture of the first fluid and the second fluid is discharged through the discharge orifice, wherein the means for delivering the second fluid into the fluid discharge conduit comprises an aperture in fluid communication with the fluid discharge conduit and a mouth of the second container, and a flow restrictor for selectively sealing off the mouth of the second container, the flow restrictor only restricting flow from the second fluid, wherein the flow restrictor moves between a closed position which seals off the mouth of the second container and an open position in which the second fluid is delivered from the mouth of the second container into the fluid discharge conduit, wherein the flow restrictor is mounted to an outer wall of the body for movement between the closed position and the open position, and wherein the means for delivering the second fluid into the fluid discharge conduit further comprises means for biasing the flow restrictor into the closed position.
