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.
