A method of filling a fluid dispenser is provided and a method for operating power driven pump in a dispenser is provided.

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 container holds a fluid. The pump is disposed between the container and the outlet nozzle. The pump includes a pump inlet in fluid communication with the container, a pump outlet in fluid communication with the outlet nozzle, and a pump chamber in fluid communication with the pump inlet and the pump outlet. 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.

A foam discharge container is a foam discharge container for discharging foam in response to a pushing operation, and includes a discharge port which is opened in a direction opposite to a pushing direction of the pushing operation and discharges foam, and a pushing portion that keeps the distance between a discharge target body receiving foam and the discharge port constant.

A system and method is provided for dispensing a substance into one of multiple patterns. The system includes a container to hold a substance and a pump in flow communication with the substance. The pump directs the substance from the container to a housing. The housing includes a first removable component with first openings that define a first pattern. The first removable component is in flow communication with the pump. The first removable component is replaceable with a second removable component defining second openings that define a second pattern different from the first pattern. The pump directs the substance through the first openings such that the substance forms a first pattern on a surface positioned proximate to the housing that is based on the first pattern of the first removable component.

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.
