  • Chemical product dispensing independent of drive fluid flow rate
    Patent number: 10392242
    Abstract: A fluid product dispenser is sized to removably receive a product package containing a supply of the fluid product. The product package includes an internally integrated fluid pump, and the dispenser includes a drive unit powered by flow of a fluid. Flow of the fluid powers the drive unit, which in turn drives the pump internal to the product package, resulting in dispensation of the fluid product in a product/fluid ratio that is independent of the fluid flow rate.

  • Retractable nozzle for dosing or dispensing high viscosity materials
    Patent number: 10376917
    Abstract: A retractable nozzle assembly is configured for dosing or dispensing highly viscous materials. The retractable nozzle assembly may be fitted to a delivery device containing a highly viscous chemical product to be dispensed. The retractable nozzle assembly may be actuated by hand, by mechanical action, or by any electromechanical device such as a dispenser. The retractable nozzle assembly includes a first path through a central bore in which the material moves at relatively slower flow rate and a secondary flow path in which the material moves at a relatively faster flow rate. The difference in flow rates at the outlet of the nozzle between the two flow paths helps to eliminate stringing and tailing of the high viscosity chemical product during dispensation.
