An automatic foam soap dispenser includes a liquid soap dispenser, an activation unit, and an actuation unit. The liquid soap dispenser includes an outlet, a fluid reservoir for containing liquid soap, and a pump being depressed for dispensing the liquid soap in the fluid reservoir to the outlet. The activation unit includes a sensor for detecting a presence of a user of the liquid soap dispenser, and a motor having a transmission shaft, wherein the motor is activated by the sensor for generating a rotational power to the transmission shaft. The actuation unit includes a pressing member and a linkage system arranged to transmit the rotational power from the motor to a linear movement to the pressing member so as to drive the pressing member to depress the pump.

Exemplary foam-at-a-distance systems include a spout, a container, and a foam generator having a suck-back mechanism located within the spout. The system includes a liquid pump chamber, an air pump chamber, a liquid conduit and an air conduit. The foam generator has a differential bore housing. The differential bore housing has a first portion with a first inside bore and a second portion with a second inside bore, wherein the first inside bore has a smaller diameter than the second inside bore. A piston having a seal extending from the piston that is in contact with the second inside bore is also included. A mixing chamber is located in the large bore. Movement of the seal in an upstream direction provides negative pressure in the second mixing chamber and draws in fluid from the outlet.

A foam dispenser includes a dispensing a mixing chamber for receiving liquid from a liquid source and air from an air source, a conduit, and an agitator downstream of the mixing chamber in the conduit.

An exemplary system for dispensing foam includes a container holding a foamable liquid, a pump, and a suck-back device. The suck back device has a housing having a small bore with first diameter and a large bore with a second diameter; a dual body piston with a first piston that reciprocates in the small bore and a second piston that reciprocates in the large bore; a flow restrictor located proximate the dual body piston, a suck back chamber formed at least in part by the large bore and the second piston, and a foam outlet. The flow restrictor is configured so that fluid flow into the suck back device causes the suck back chamber to compress and when the fluid flow stops, a biasing member causes the suck back chamber to expand and suck back residual foam into the suck back chamber.

A foaming dispenser has a mixing chamber configured to mix a liquid and a gas to foam the liquid, a first liquid passage configured to supply the liquid to the mixing chamber, and a discharge opening configured to discharge the foamed liquid, the mixing chamber includes a plurality of second liquid passages branching and extending from the first liquid passage, a liquid passage meeting where one second liquid passage meets another second liquid passage, a gas passage configured to supply the gas to the liquid flowing from the plurality of second liquid passages to the liquid passage meeting, and a hole that is provided on a downstream side of the gas passage and communicates with the discharge opening.

A fluid dispenser having a pump mechanism that dispenses a dose of fluid when a movable pump member of the pump mechanism is moved between an extended position and a retracted position. A pump engagement body engages with the movable pump member for effecting movement of the movable pump member. A first cam surface and a second cam surface are connected to the pump engagement body, at least one of the first cam surface and the second cam surface comprising an adjustable cam surface whose location relative to the pump engagement body is selectively adjustable. A camming body engages with the first cam surface and the second cam surface to effect movement of the pump engagement body, and a dose adjustment mechanism allows the location of the adjustable cam surface relative to the pump engagement body to be selected.

An organic liquid soap composition; and a foam producing soap product comprising: a) a foamable organic liquid soap composition comprising the anti-microbial active ingredients of: organic shea butter; organic spearmint oil; USDA approved lime oil; organic thyme oil; and organic rosemary extract; and, b) a foam soap dispenser for dispensing the organic liquid soap composition as a premeasured amount of foaming soap, wherein the foam dispenser comprises: a recyclable plastic; a bottom front tab comprising a green color and a label indicating the composition is an organic soap. The organic soap composition may further comprise: glycerin; saponified organic coconut oil; organic olive oil; organic sunflower oil; organic jojoba oil; and organic aloe vera. And the organic soap composition has a shelf-life of about three years, and able to eradicate about 74.6% through 77.6% of the bacterial strain Staphylococcus aureus after at least one minute of direct contact with the composition.
