Patent ID: 11013375

Abstract:
A foaming component for use in a foaming liquid dispenser, and an insert arranged so that it may be inserted into a liquid dispenser comprising the foaming component. The foaming component comprises a liquid chamber; an air chamber; a sparging component, which comprises a sparging interface and a foaming region; an exit aperture; and a pumping mechanism. The pumping mechanism is arranged such that it can transfer liquid from the liquid chamber directly to the foaming region, and air from the air chamber to the foaming region, via the sparging interface. The forcing of air through the sparging interface causes bubbles to form in the liquid located in the foaming region, resulting in a foamed mixture for dispensing. The pumping mechanism is then used to transfer the foamed mixture from the sparging component through the exit aperture, wherein the sparging interface is arranged such that at least a portion of the foaming region is positioned in between opposing surfaces of the sparging interface.
