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.

A foam dispensing container (100) has a container body (40) that reserves a liquid agent (L); a head part (30) that has an outlet (20), and dispenses the liquid agent (L) delivered from the container body (40) through the outlet (20) into foam; and a pump head part (32) that allows dispensing of a predetermined amount of the foamy liquid agent (foam) through the outlet (20) each time it accepts a user's operation. The outlet (20) is formed with a contiguous geometry narrowed from an intended shape. A foam, dispensed through the outlet (20) as a result of a single or multiple operations of the pump head part (32), is built up into the intended shape in a plan view seen in the dispensing direction.

A foam dispenser includes a housing, a drive motor, and a foam pump. The foam pump includes a pump housing, and a molded multi-chamber diaphragm. The molded multi-chamber diaphragm includes a liquid pump diaphragm having a liquid pump stem and two or more air pump chambers each having an air pump stem. The length of the liquid pump stem is longer than the air pump stem. The foam pump further includes one or more outlet valves, a mixing chamber, an outlet for dispensing foam wherein the outlet is in fluid communication with the foam cartridge; and an actuator for sequentially actuating the liquid pump chamber and the two or more air pump chambers, wherein there is lost motion between the actuator and the liquid pump diaphragm.

An automated flowable material dispenser for dispensing flowable material from a flowable material container is provided. In one embodiment, the dispenser may include a dispenser housing configured to receive the flowable material container therein, a solenoid valve assembly positioned within the dispenser housing, and a biasing member configured to bias the flowable material container toward the solenoid valve assembly and to move the flowable material container from an unactuated configuration to an actuated configuration. The dispenser housing may define a dispensing opening along a bottom end of the dispenser housing and may be configured to move between an open configuration and a closed configuration. The solenoid valve assembly may be positioned above the dispensing opening and configured to control dispensing of the flowable material from the dispenser.
