Foaming soap dispensers

A method of dispensing foamed soap, the method comprising:

• drawing liquid soap from a reservoir;
• mixing the liquid soap with air to form aerated soap;
• encouraging the aerated soap into and out of a pumping assembly;
• converting the aerated soap into foamed soap;
• and
• dispensing the foamed soap through a nozzle.

A dispensing device comprising:

• a reservoir configured to store a liquid product;
• a pumping assembly configured to draw the liquid product from the reservoir and to draw air through an air inlet, the liquid product and the air mixing to form an aerated product;
• wherein the pumping assembly comprising a plurality of compartments and a plurality of resilient members, each of the compartments comprising at least one of the resilient members, each of the resilient members being movable between a convex state and a concave state;
• wherein each resilient member extends outward of its respective compartment in the convex state and extends into its respective compartment in the concave state;
• a motor configured to drive an actuation member, the actuation member configured to engage and disengage with the resilient members such that the resilient members are moved between the convex state and the concave state, thereby providing a flow of aerated product into and out of the compartments;
• a foaming unit configured to convert the aerated product into a foamed product;
• and
• a discharge nozzle configured to dispense the foamed product out of the dispensing device.

A reservoir configured to removably engage with a pumping assembly, the reservoir comprising:

• a top comprising an outlet, the outlet comprising a normally-closed valve;
• a bottom;
• a sidewall;
• an inner chamber configured to contain a volume of liquid soap;
• and
• wherein, when the reservoir is engaged with the pumping assembly, a projection of the pumping assembly is received in the valve of the top of the reservoir, thereby opening the valve and allowing liquid soap to flow out of the reservoir.
