Patent ID: 8281958

Claim:
A foaming component for use in association with a foam skin care dispenser and foamable liquid including a plurality of particles having a predetermined average diameter, the foam skin care dispenser having a user activated pump means for concurrently forcing a predetermined ratio of air and the foamable liquid into the foaming component, the foaming component comprising: a microporous air sparging element having an upstream end and a downstream end defining a length thereof; a mixing chamber on one side of the microporous air sparging element and the air sparging element defining a portion of the mixing chamber, the mixing chamber having a cross sectional width that is 1.5 to 8 times the average diameter of the plurality of particles and the mixing chamber having a liquid inlet proximate to the upstream end of the microporous air sparging element; an air chamber on the other side of the microporous air sparging element and the microporous air sparging element defining a portion of the air chamber and the air chamber having an air inlet proximate to the upstream end of the microporous air sparging element; a mixing chamber outlet downstream of the liquid inlet in the mixing chamber whereby on activation of the user activated pump means the foamable liquid is forced into the mixing chamber, and air is forced into the air chamber and through the microporous air sparging element to form a plurality of bubbles in the foamable liquid, and a density of the plurality of bubbles in the foamable liquid increases from the liquid inlet to the mixing chamber outlet to form a foamed liquid.
