A dispenser for dispensing a metered dose of foam or liquid from a reservoir includes means for applying gas pressure either directly or indirectly to a liquid contained in the reservoir for dispensing a liquid or foam through a nozzle. Instead of using a direct pump, the dispenser uses gas pressure inside the dispenser that pushes the liquid out of the reservoir without coming into contact with the reservoir. The dispenser can include a battery operated gas pressure pump and a sensor that senses pressure within the dispenser. In one aspect, an actuator can open a valve for dispensing metered doses of a liquid or foam.

A liquid soap dispenser having a press-type nozzle that dispenses liquid soap from the nozzle by being pressed by hand includes a dispenser body, a nozzle, a pump, and the like. The dispenser body is supported inside an upper storage portion by a lower bracket and an upper bracket. A connecting member connects a vertically moving member and the nozzle. When a user places a hand below the nozzle, a human body detection unit detects the hand, and a control unit causes a motor to rotate in a forward direction and raise the vertically moving member from a lower limit position to an upper limit position; and by raising the nozzle from the lower limit position to the upper limit position via the connecting member, liquid soap is automatically dispensed from the nozzle.

A total-use dispenser for dispensing a fluid product therefrom. A total-use dispenser may have a body forming an enclosure having both a top opening and a bottom outlet and a tapering portion that tapers down toward the bottom outlet and a pump configured in the top opening to dispense the fluid product from the dispenser. The pump may be configured in the top opening to pump air into the rigid body to force fluid product therefrom. The fluid product may be dispensed from a bottom outlet or from a spout coupled with a spout conduit that extends into the squeezable body of the total-use dispenser. The total-use dispenser enables substantially all the fluid product to be dispensed from the enclosure, such as at least 90% by weight, at least 97% by weight and most preferably 99% or more by weight.

A water faucet system including a faucet having a neck comprising a water passageway and liquid soap delivery line, both integrated within the neck assembly. The water faucet system features a streamlined neck assembly that includes a water outlet or spout, located at the distal portion of the neck assembly, and additionally includes a separate soap outlet located at a predetermined location. The soap delivery (soap dispensing) is initiated by a user performing an activation event directed to a sensor system located in the neck assembly. In preferred embodiments, the sensor system utilizes touchless type sensors so to avoid any physical contact with the neck assembly.

A fluid dispenser includes a reservoir for storing a fluid, an outlet port connected with the reservoir by a dispense passage for dispensing fluid stored in the reservoir, an external supply port connected with the reservoir by a supply passage to supply fluid to the reservoir, a supply access valve defining a portion of the supply passage between the external supply port and the reservoir, and a controller in circuit communication with the supply access valve for controller operation of the supply access valve from a closed position to an open position in response to receipt of an authorized supply signal at the controller.

An exemplary foam dispensing system includes a dispenser housing configured to be mounted below a counter, a spout configured to be mounted above a counter, a container supported by the dispenser housing, a pump in fluid communications with the container and configured to be mounted below a counter. The pump includes an air pump portion and a liquid pump portion. The pump also includes a mixing chamber. Liquid pumped from the liquid pump portion is mixed with air pumped from the air pump portion in the mixing chamber. A dispense tube is included that is configured to extend from the mixing chamber below a countertop to one or more mix media located above the countertop proximate an end of the spout. The one or more mix media are located near an end of the spout. An outlet nozzle is also provided and is located downstream of the one or more mix media.

Table top sanitizer dispenser bottle bases are disclosed herein. An exemplary table top sanitizer dispenser bottle base includes a movable upper housing, the upper moveable housing has a floor with an aperture located therein and a peripheral wall. The top sanitizer dispenser bottle includes a lower stationary housing. The upper movable housing is connected to the lower stationary housing and is configured to move linearly upward and downward with respect to lower stationary. One or more biasing members bias the upper movable housing upward. A switch is included and the upper movable housing has an engagement member or surface for actuating the switch upon downward movement of the upper movable housing. At least one of a visual indicator and an audible indicator are also included. Control circuitry is provided for activating the one or more of a visual indicator and audible indicator when the engagement member actuates the switch.

A reservoir assembly for use with a liquid dispenser is provided. The reservoir assembly includes a connecting member housing having a reservoir connecting surface and a switch. The reservoir connecting surface having a first switch contact surface disposed within a first protrusion member. The assembly also includes a container housing for holding a quantity of a liquid product. The container housing configured to be removably attached to the connecting member housing. The container housing includes a main container and a connecting member housing surface. The connecting member housing surface includes a second switch contact surface configured in a first weakened region. After contact of the first switch contact surface and the second switch contact surface, the protrusion member is configured to engage the first weakened region such that the first weakened region breaks away from the connecting member housing surface such that first switch contact surface and second switch contact surface are unable to make contact. Counter-mounted liquid product dispensing apparatuses and systems for monitoring a refill status of a liquid product dispensing apparatus are also provided.

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 dispensing system includes an above-deck nozzle portion, a reservoir for holding fluid, a foam pump, a multi-lumen dispense passage, and a mixing portion. The above-deck nozzle portion has a dispenser outlet and is disposed above a counter. The foam pump is disposed below the counter and includes at least one liquid pump chamber in fluid communication with the reservoir, at least one air pump chamber, and a pump outlet. The multi-lumen dispense passage includes an inlet, an outlet, at least one liquid lumen, and at least two air lumens. The inlet is in fluid communication with the pump outlet, the outlet is in fluid communication with the dispenser outlet, and the at least one liquid lumen and the at least two air lumens are each in fluid communication with the inlet and the outlet of the multi-lumen dispense passage. The mixing portion is disposed between the multi-lumen dispense passage and the dispenser outlet.
