| abstract |
An apparatus for diluting and dispensing a liquid concentrate with a liquid diluent to form a use solution wherein the use solution has a higher viscosity than either the concentrate or the diluent is provided. The apparatus includes an aspirator (12), a liquid diluent conducting means (14), a liquid concentrate conducting means (16), and a liquid conducting outlet means (18). The aspirator has a first inlet port (20), a second inlet port (22), and an outlet port (24). The first inlet port is connected to the liquid diluent conducting means for receiving a stream of the liquid diluent and the second inlet port is connected to the liquid concentrate conducting means for receiving a stream of the liquid concentrate at atmospheric pressure. The liquid conducting outlet means is connected to the outlet port for dispensing the use solution from the apparatus. The geometry of the aspirator nozzle and the fluid passaways in the dispenser are adapted to a high viscosity dilute product. |
