  • Dispensing a viscous use solution by diluting a less viscous concentrate
    Patent number: 5816446
    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, a liquid diluent conducting path, a liquid concentrate conducting path, and a liquid conducting outlet path. The aspirator has a first inlet port, a second inlet port, and an outlet port. The first inlet port is connected to the liquid diluent conducting path for receiving a stream of the liquid diluent and the second inlet port is connected to the liquid concentrate conducting path for receiving a stream of the liquid concentrate at atmospheric pressure. The liquid conducting outlet is connected to the outlet port for dispensing the use solution from the apparatus. The geometry of the aspirator nozzle and the fluid passageways in the dispenser are adapted to a high viscosity dilute product.
