A hand foam pump fabricated entirely from plastic components for dispensing foamable liquids, is provided. The hand foam pump includes an actuator, a closure, a housing, cylinder bores for an air piston and a liquid piston within the housing and an air piston and a liquid piston fixed to a stem, wherein the air and liquid pistons are reciprocally mounted within the cylinder bores, and check valves, among other components. An elastic, dome shaped, plastic return spring is utilized to return the actuator to its rest position after actuation. The plastic return spring is positioned over the closure and below the actuator. The all plastic hand foam pump is suitable for dispensing foamable liquids from a dispenser bottle. Used pumps do not require disassembly to be recycled.

A soap dispensing nozzle structure is mounted to a soap dispenser. The soap dispenser includes a soap bottle. The soap bottle is connected with a conveying member. The conveying member is connected with a dispensing member. The dispensing member has a dispensing opening. The dispensing opening is provided with a joint. The joint is connected with a soap dispensing nozzle. The soap dispensing nozzle includes a nozzle body. The nozzle body has a mounting portion, a body portion, and a reduced portion. The nozzle body has a passage therein. The passage has a pressuring hole. Thereby, through the reduced portion and the pressurizing hole, the force of discharging the liquid soap is strong, and it is not easy to remain excessive residual foam.

Exemplary embodiments of manual dispensers and actuating mechanisms are disclosed herein. An exemplary dispenser includes a housing, a receptacle for receiving a container of fluid and an actuating mechanism for causing fluid to be dispensed from the container. The actuation mechanism has a first pivot arm having a pivot point on a first end and a cam on a second end and a second pivot arm having a pivot point a first end and a curved contact surface on a second end. The actuating mechanism includes a pushbar. One of the first and second pivot members is connected to the pushbar. When the pushbar is pushed inward, the cam is configured to travel along the curved contact surface. Movement of the cam along the curved contact surface moves the engagement mechanism upward and downward in a substantially linear motion when the engagement mechanism is connected to a pump to cause the pump to prime with fluid and dispense the fluid.
