Exemplary power systems for dynamically controlling a dispenser drive motor for dispensing soap, sanitizing or lotion. An exemplary soap, sanitizing or lotion dispenser includes a housing, a receptacle for receiving a container for holding a soap, sanitizing or lotion, a container of soap, sanitizing or lotion and a pump secured to the container. The exemplary soap, sanitizing or lotion dispenser includes a power source, a motor and an actuator that couples the motor to the pump. In addition, the exemplary soap, sanitizing or lotion dispenser includes pulse width modulation circuitry in circuit communication with the power source and the motor. Movement of the actuator one actuation cycle dispenses a dose of soap, sanitizing or lotion. The pulse width modulation circuitry provides a plurality of voltage pulses to the motor to move the actuator one actuation cycle.

Dispensers and dispenser systems for precisely controlled output dosing of soap or sanitizer

Exemplary sanitary soap refilling systems and methods are disclosed herein. An exemplary refill refilling system includes a housing, a pump located within the housing, and a bulk storage tank connector. The bulk storage tank connector having a liquid outlet and an air inlet. A liquid inlet conduit is in fluid communication with the pump the liquid outlet. A refill connector is included. The refill connector has a liquid inlet and an air outlet. The refill connector air outlet and the bulk storage tank connector air inlet are in fluid communication with one another. The refill liquid inlet is in fluid communication with the pump.

Refilling systems, refillable containers and method for refilling containers

A dispenser includes a housing, an inverted container disposed in the housing, a outlet nozzle, a pump, a first check valve, and a second check valve. The pump is disposed between the container and the outlet nozzle. The pump includes a pump inlet a pump outlet, and a pump chamber. The pump chamber is movable between an expanded position and a compressed position. The first check valve is disposed between the pump and the outlet nozzle, and the first check valve has a first cracking pressure. The second check valve is disposed between the first check valve and the outlet nozzle, and the second check valve has a second cracking pressure. The second cracking pressure of the second check valve is greater than the first cracking pressure of the first check valve.

Outlet valve arrangements for enhanced pump efficiency

Exemplary soap, sanitizer and lotion dispensers are disclosed herein. An exemplary dispenser includes a housing; a receptacle for receiving a container; a container of fluid comprising soap, sanitizer or lotion; a pump in fluid communication with the container; a power source; a pump coupled to a motor and pulse width modulation circuitry in circuit communication with the power source and the motor. The pulse width modulation circuitry is initially set to cause a selected dose of fluid to be dispensed at a base speed. A sensor for detecting a parameter indicative of an actual speed of a dispense of the fluid is also included. When the actual speed of the dispense of fluid is less than the base speed or greater than the base speed, the pulse width modulation circuitry adjusts the pulse width to cause the speed of a following dispense of fluid to be closer to the base speed.

Touch-free dispensers

An dispenser includes a housing, a container disposed in the housing for holding a liquid, a nozzle, and a pump. The pump is disposed between the container and the nozzle. The pump includes a pump inlet, a pump outlet, a pump chamber, a first check valve, and a second check valve. The pump inlet is in fluid communication with the container and the pump chamber, and the pump outlet is in fluid communication with the pump chamber and the nozzle. The pump chamber is movable between an expanded position and a compressed position. The first check valve is disposed between the container and the pump, and the first check valve has a first cracking pressure. The second check valve is disposed between the first check valve and the pump, and the second check valve has a second cracking pressure. The first cracking pressure of the first check valve is greater than the second cracking pressure of the second check valve.

Double inlet valve for enhanced pump efficiency

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.

Sequentially activated multi-diaphragm foam pumps, refill units and dispenser systems

A refillable fluid container for a fluid dispenser is provided. The refillable fluid dispenser includes a body, an output port and a dispensing mechanism. The body includes at least one wall that defines a reservoir for storing fluid therein. The output port is in fluid communication with the reservoir. The dispensing mechanism is associated with the output port. The dispensing mechanism is selectively operable between a closed position and an opened position. A fluid dispenser is also provided.

Fluid dispenser and first and second fluid containers for a fluid dispenser

A dispenser having a housing, a container disposed in the housing for holding a liquid, a nozzle, and a pump. The pump includes a pump inlet, a pump outlet, a pump chamber. The pump inlet is in fluid communication with the container and the pump chamber, and the pump outlet is in fluid communication with the pump chamber and the nozzle. The pump chamber is movable between an expanded position and a compressed position. A first check valve is disposed between the container and the pump, and the first check valve has a first cracking pressure. A second check valve is disposed between the first check valve and the pump, and the second check valve has a second cracking pressure. The first cracking pressure of the first check valve is greater than the second cracking pressure of the second check valve.
