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 non-antimicrobial cleansing composition is disclosed comprising from about 10.0 wt. % to less than about 40 wt. % of one or more C-Calcohols; about 0.5 wt. % to about 10.0 wt. % of at least one primary surfactant; 0 wt. % to about 10.0 wt. % of at least one secondary surfactant, with the primary and secondary surfactants having an HLB value greater than 8; a pH adjusting agent; and water. The composition does not achieve a microbial kill level greater than 2.0 log.

Alcohol containing non-antimicrobial cleansing composition

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

A low-water cleansing composition is provided that includes 5.0 wt. % to less than 40 wt. % of one or more C-Calcohol, at least 10.0 wt. % of a mixture of two or more surfactants, at least 0.05 wt. % of a pH adjuster; and water, the concentrations being based on a total weight of the low-water cleansing composition.

Alcohol containing low-water cleansing composition

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 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.
