Abstract

A trigger operated fluid delivery system for dispensing two different fluids. The fluid delivery system includes a first container having a first fluid that dispenses to a fluid discharge orifice via a fluid inlet conduit by a pump and pump chamber. The fluid delivery system includes a second container having a second fluid, with a device for delivering the second fluid into the fluid discharge conduit. The two fluids mix in the fluid discharge conduit prior to dispensation through the discharge orifice.

Claims (30)

1. A fluid delivery system for dispensing two fluids, the fluid delivery system comprising:

a first container having a first fluid;

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 first fluid discharge conduit downstream of the pump chamber, the first 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 first fluid discharge conduit;

a second container having a second fluid; and

means for delivering the second fluid into the first fluid discharge conduit whereby the second fluid mixes with the first fluid when the first fluid is discharged into the first fluid discharge conduit such that a mixture of the first fluid and the second fluid is discharged through the discharge orifice; and

a second fluid discharge conduit downstream of the pump chamber, the second fluid discharge conduit being in fluid communication with the pump chamber and the discharge orifice.

2. The fluid delivery system of claim 1 further comprising:

a flow selector located between the pump chamber and the first fluid discharge conduit and located between the pump chamber and the second fluid discharge conduit, the flow selector having a first position in which the first fluid is delivered from the pump chamber into the first fluid discharge conduit and having a second position in which the first fluid is delivered from the pump chamber into the second fluid discharge conduit.

3. A fluid delivery system for dispensing two fluids, the fluid delivery system comprising:

a first container having a first fluid;

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 first fluid discharge conduit downstream of the pump chamber, the first fluid discharge conduit being in fluid communication with the pump chamber and a first discharge orifice, the pump discharging the first fluid from the pump chamber into the first fluid discharge conduit;

a second container having a second fluid; and

means for delivering the second fluid into the first fluid discharge conduit whereby the second fluid mixes with the first fluid when the first fluid is discharged into the first fluid discharge conduit such that a mixture of the first fluid and the second fluid is discharged through the first discharge orifice; and

a second fluid discharge conduit downstream of the pump chamber, the second fluid discharge conduit being in fluid communication with the pump chamber and a second discharge orifice.

4. The fluid delivery system of claim 3 further comprising:

a flow selector located between the pump chamber and the first fluid discharge conduit and located between tile pump chamber and the second fluid discharge conduit, the flow selector having a first position in which the first fluid is delivered from the pump chamber into the first fluid discharge conduit and having a second position in which the first fluid is delivered from the pump chamber into the second fluid discharge conduit.

5. A fluid delivery system for dispensing two fluids, the fluid delivery system comprising:

a first container having a first fluid;

a fluid inlet conduit in fluid communication with the first container;

a first fluid discharge conduit in fluid communication with the fluid inlet conduit;

a second fluid discharge conduit in fluid communication with the fluid inlet conduit;

a second container having a second fluid;

means for delivering the second fluid into the first fluid discharge conduit; and

means for pumping the first fluid from the first container through the fluid inlet conduit and into the first fluid discharge conduit and into the second fluid discharge conduit whereby the second fluid mixes with the first fluid when the first fluid is pumped into the first fluid discharge conduit such that a mixture of the first fluid and the second fluid can be discharged through a discharge orifice in fluid communication with the first fluid discharge conduit.

6. The fluid delivery system of claim 5 further comprising:

a flow selector located between the fluid inlet conduit and the first fluid discharge conduit and located between the fluid inlet conduit and the second fluid discharge conduit, the flow selector having a first position in which the first fluid is delivered from the fluid inlet conduit into the first fluid discharge conduit and having a second position in which the first fluid is delivered from the fluid inlet conduit into the second fluid discharge conduit.
