## Abstract

A liquid dispensing system comprises a container enclosing a chamber. A flexible bag in the chamber contains a first liquid. First and second conduits are contained in the chamber. The first conduit connects the chamber to an outlet port in the container where the second conduit connects the bag to the first conduit. A supply source introduces a pressurized second liquid into the chamber. The first conduit serves to direct an existing flow of the second liquid from the chamber to the outlet port, with the pressurized second liquid serving to collapse the bag and expel the first liquid contained therein via the second conduit to the first conduit for mixture with the exiting flow of the second liquid. The second conduit lacks flow restrictions, such as metering orifices or the like.

## Claims

### Claim 1

A liquid dispensing system comprising:
a first container (10) enclosing a chamber (12);
a flexible container (18) in said chamber (12);
a first liquid (20) contained in said flexible container (18);

supply means (48) for introducing a pressurized second liquid (50) into said chamber (12), said first conduit (22) serving to direct an exiting flow of said second liquid (50) from said chamber (12) to said outlet port (26), with said pressurized second liquid (50) serving to collapse said flexible container (18) and expel the first liquid (20) contained therein via said second conduit (24) to said first conduit (22) for mixture with the exiting flow of said second liquid (50).

### Claim 2 (depends on 1)

The liquid dispensing system of claim 1 wherein said supply means (48) includes a constant flow valve (52) located externally of said first container (10).

### Claim 3 (depends on 1)

The liquid dispensing system of claim 1, wherein said first check valve (32) prevents a reverse flow of liquid into said chamber (12) or further comprising a second check valve (38) on said second conduit (24) for preventing a reverse flow of liquid into said flexible container (18).

### Claim 4 (depends on 1)

The liquid dispensing system of claim 1 wherein said first conduit (22) includes a metering orifice.

### Claim 5 (depends on 1)

The liquid dispensing system of claim 1 wherein said second conduit (24) comprises a flexible tube (36)

### Claim 6 (depends on 3)

The liquid dispensing system of claim 3 wherein said first and second check valves (32, 38) comprise duckbill valves.

### Claim 7 (depends on 1)
