First Claim
Patent Images
1. A method for dispensing incompatible liquid products from a dispenser, comprising:
- providing a first and second aspirator each having a diluent inlet port, a plurality of product inlet ports and an outlet port;
aspirating a first liquid product through a product inlet port of the first aspirator;
aspirating a second liquid product incompatible with the first liquid product through a product inlet port of the second aspirator; and
dispensing the first liquid product out an outlet port of the first aspirator and the second liquid product out an outlet port of the second aspirator in separation from the first liquid product.

Abstract
A method and system provides for dispensing incompatible products. Separate aspirator assemblies (12A and 12B) are connected in fluid communication with a single liquid diluent source (54). A first set of liquid products (48A-51A) are drawn through aspirator assembly (12A) and a second set of liquid products (48B-51B) having a product incompatible with the first set are drawn through another aspirator assembly (12B). Incompatible liquid products are thereby dispensed independent of and in separation from one another to an appliance for use.

11. A method for dispensing and preserving the effectiveness of liquid products during dispensing, comprising:
-
providing at least two aspirators each having a diluent inlet port, a plurality of product inlet ports and an outlet port; passing a liquid diluent at a pressure elevated from its source pressure through the diluent inlet port of each aspirator; selectively aspirating a first set of liquid products through the plurality of product inlet ports of the first aspirator separately from a second set of liquid products through the plurality of product inlet ports of the second aspirator; and dispensing at least one of the liquid products of the first set out the outlet port of the first aspirator and at least one of the liquid products of the second set out the outlet port of the second aspirator in separation from each other to preserve the effectiveness of each product. - View Dependent Claims (12, 13, 14)

15. A product dispensing system configured to dispense incompatible liquid products, comprising:
-
a boost pump having a pump inlet for receiving a liquid diluent at a source pressure and a pump outlet for delivering the liquid diluent at an elevated pressure; a first and second aspirator each having a diluent inlet port for receiving the liquid diluent at the elevated pressure, a plurality of product inlet ports for receiving a liquid product and an outlet port for dispensing; a first set of the liquid products connected in liquid communication to the plurality of product inlet ports of the first aspirator for aspirating each liquid product into the first aspirator; a second set of liquid products connected in liquid communication to the plurality of product inlet ports of the second aspirator for aspirating each liquid product into the second aspirator; and at least one product of the second set of liquid products being incompatible with at least one product of the first set of liquid products. - View Dependent Claims (16, 17, 18, 19, 20)
